    MULTIPLE CAVITIES OVEN FUNDAMENTALS OF THE INVENTION [001] The present invention relates to food preparation ovens and, in particular, to a multizone oven that provides air dispensing close to heated air directly through the shelves. [002] Convection ovens can improve the cooking speed by dispersing stagnant air that can provide an insulating blanket around the food in an oven. Such ovens typically provide a blower that blows heated air through an opening in the wall of the cooking cavity, the opening positioned in a way to increase air turbulence in order to provide uniform cooking.
    [003] A drawback of convection shafts is that different volumes of food, as well as different food loading arrangements, can radically change the airflow pattern and consequently the cooking process. This may require a chef to develop extensive experience of how to load and operate the oven when different types of food items, different volumes of food or different placement of food in the cooking cavity are used.
    [004] Higher cooking speeds and more consistent cooking can often be achieved by reducing the length of the path between heated air and food, for example, dispensing heat through an arrangement of horizontally dispersed openings positioned directly above and / or below of the food, thereby increasing the surface area of food that is directly contacted by the heat dispensed. This close air dispensing can improve cooking uniformity in a variety of different food heating patterns and for different types of food. In this regard, the short air delivery distance provides more predictable, treatable airflow patterns. Ordinary furnaces of this type provide a set of airflow openings

    2/30 up and down in opposition to the upper and lower walls of the oven cavity.
    [005] It would be desirable to provide we were using this nearby air dispensing that could simultaneously cook a variety of different foods at different temperatures. Air furnaces near two cavities are relatively simple to build by simply stacking two single cavity ovens one on top of the other. Unfortunately, additional cavities can excessively increase the height of the oven or reduce the cooking volume due to the substantial space between cavities required for insulation between the cavities and for the pressure chambers required for air dispensing.
    SUMMARY OF THE INVENTION [006] The present invention provides a compact multizone oven using close air dispensing, enabled by the use of extremely low profile separators between the cavities. The present inventors realized that absolute isolation between the cavities is not required and that substantial leakage can be managed by controlling the active feedback of the cavity temperature and correctly managing the cavity loading, among other techniques. In addition, an innovative air distribution plate design operates with relatively thin pressure chambers. By radically reducing the thickness of the separation between the different cavities, three- and four-zone sections can be easily obtained while still satisfying the desired ergonomic height restrictions.
    [007] Specifically then, at least one embodiment of the invention provides a multi-cavity oven having a housing defining an interior cooking volume surrounded by insulated external walls and at least one door that can open and close to provide access to the interior cooking volume . A set of shelves subdivides the volume

    3/30 cooking in cooking cavities, the shelves providing separate upper and lower air channels, each going from the respective air intakes to the respective airflow openings directed upwards and airflow openings directed downwards. Each cavity provides a separate blower that circulates air from the cavity to a lower air channel on a shelf above the cavity and an upper air channel on the shelf below the cavity, and each cavity provides a separate heater and a thermal sensor placed in the circulated air. after airflow openings, but before the heater. A controller receives a control setpoint and a signal from the thermal sensor to control the heater.
    [008] And so a feature of at least one embodiment of the invention is to provide a multi-zone air oven nearby in which the cavity shelves alone separate the oven cavities thereby greatly reducing the height of the oven and increasing the volume of usable cooking.
    [009] In this respect, the shelves may have a vertical thickness of less than 76.2 millimeters (three inches) or preferably less than 50.8 millimeters (two inches) measured between a greater extension of the airflow openings of the air channels. upper air and the lower extension of the air flow openings of the lower air channels, and / or the upper and lower air channels of each shelf may have an average separation of less than 25.4 millimeters (one inch) or preferably less than 12.7 millimeters (half an inch). Alternatively or additionally, the effective resistance between the upper and lower channels can be less than half the wall of the external oven.
    [0010] And thus a feature of at least one embodiment of the invention to accommodate greater heat leakage between the cavities in order to maximize the cooking volume while reducing the height of a multizone oven with air dispensing
    Petition 870190087795, of 09/06/2019, p. 9/47 next. This design can be contrasted by conventional science that requires standard oven wall grade insulation between cavities that operate at different temperatures. Furthermore, the inventors realized that it is possible to build an operable air distribution plate system using relatively narrow shelf channels.
    [0011] The controller can operate to control the air velocity through the channel to prevent a gain or loss of the air temperature of the air that passes through the channel, from the entrance to the air current openings caused by thermal transfer with air channel. adjacent air, more than -15 degrees Celsius (five degrees Fahrenheit).
    [0012] It is thus a feature of at least one modality of the invention to manage the heat transfer between cavities between values that can be actively compensated by the temperature controls independent of the cavities.
    [0013] The shelves can be removably replaceable from the inside cooking volume.
    [0014] And thus a feature of at least one embodiment of the invention is to provide a multizone oven having compact partitions that allow prompt useful removal for cleaning or changing cavity sizes.
    [0015] The shelves may consist of a separately removable lower pressure chamber that provides lower air channels and a separately removable upper pressure chamber that provides upper air channels, at least one pressure chamber providing a barrier wall that separates the upper and lower air channels.
    [0016] It is thus a feature of at least one embodiment of the invention to reduce the weight and volume of the shelf by allowing it to be separated into different pressure chambers. Another objective of the invention is to provide a pressure chamber component that can be used
    Petition 870190087795, of 09/06/2019, p. 10/47
    5/30 both for the shelves and also for the top and bottom of the cooking volume where only individual airflow directions are required. [0017] The inner cooking volume can provide inwardly extending shelf supports that support the lower pressure chamber, and the upper pressure chamber can directly support the lower pressure chamber to be supported by it.
    [0018] And so a feature of at least one embodiment of the invention is to minimize the shelf height by ensuring a fair support of the pressure chamber simplified by the direct support.
    [0019] Each pressure chamber can provide an air distribution plate that holds the airflow openings and an opposite barrier wall together with the air distribution plate defining the channel, and the air distribution plate and wall barrier can be user separable components.
    [0020] It is thus a feature of at least one embodiment of the invention to provide pressure chambers (and shelves) with interior air channels that are, however, easily cleaned by separating the pressure chambers and channel components.
    [0021] The upper and lower pressure chambers can provide different air distribution plates providing a different configuration of openings.
    [0022] And thus a feature of at least one embodiment of the invention allows adaptation of the air distribution plate openings to the air flow within the shelves to provide uniform cooking.
    [0023] The oven can include a collector that communicates between each blower and two channels to provide greater air flow through an upper channel of the lower pressure chamber than to the corresponding lower channel of the upper pressure chamber that flanks a cavity.
    Petition 870190087795, of 09/06/2019, p. 11/47
    6/30 [0024] It is thus a characteristic of at least one modality of the invention to manage airflow ratios through the action of the collector to optimize cooking performance while simplifying the construction of the shelves and minimizing their thickness. The multi-cavity oven can provide a single pressure chamber at the top and bottom of the inner cooking volume providing an upper surface of the uppermost cavity and a lower surface of the lowermost cavity.
    [0025] And so a feature of at least one embodiment of the invention employs the design of the pressure chamber to provide the airflow openings downwards and the airflow openings upwards without requiring a shelf. complete or a new part.
    [0026] The multi-cavity oven may include at least one rack that can be positioned on an upper surface of at least one shelf, the rack supported by the shelf to be stationary with respect to the shelf in spaced relation to the air currents directed upwards.
    [0027] And so a feature of at least one embodiment of the invention provides a simple method of ensuring that the airflow out of the lower airflow openings is unobstructed by the food placed on the shelf, as can be a problem with the stationary positioning of the rack.
    [0028] The temperature probe can be positioned on an oven wall that communicates with the cavity through intake slits to be upstream of the cavity heater and downstream of the air currents.
    [0029] It is thus a feature of at least one embodiment of the invention to place the temperature probe in such a way as to allow compensation for heat transfer between different temperature cavities. In the manner thus positioned (as opposed to being directly
    Petition 870190087795, of 09/06/2019, p. 12/47
    7/30 downstream of the heater and upstream of the air currents), the temperature sensor can provide guidance regarding the sensing and compensation of heat transfer between cavities.
    [0030] The multi-cavity oven may additionally include a compliant seal positioned between the inner surface of at least one door and a front edge of the shelf to block airflow beyond the shelf between adjacent cavities.
    [0031] And so a feature of at least one embodiment of the invention is to minimize the air flow between the cavities, such an air flow potentially resulting in undesirable heat transfer, as well as potential flavor transfer.
    [0032] An upper wall of the lower air channel of each shelf can tilt down from the air inlet and a lower wall of the upper air channel of each shelf can tilt up from the air inlet to provide a gap of air between the upper and lower channels as much as possible with reduced air flow through the channels as it moves away from the air intakes.
    [0033] It is thus a feature of at least one embodiment of the invention to increase the insulation space between the shelves when the thickness of the shelf channel can be reduced due to the reduced flow of air towards its tip.
    [0034] The controller can communicate with a display that guides the user in loading food into cavities not currently used for cooking food based on the temperatures of the cavities currently used for cooking food.
    [0035] It is thus a feature of at least one modality of the invention to manage the "intelligent" loading of the oven to minimize the temperature flow between the cavities and thus the heat transfer.
    Petition 870190087795, of 09/06/2019, p. 13/47
    8/30 [0036] The multi-cavity oven can provide at least three cavities, and a separation between the upper wall of the inner cooking volume and a lower wall of the inner cooking volume can be less than 635 millimeters (25 inches). Each cooking cavity can be at least 127 millimeters (five inches) high between a bottom surface of the upper shelf airflow openings on a top surface of the lower shelf airflow openings.
    [0037] And so a feature of at least one embodiment of the invention is to provide a multizone oven using nearby air dispensing having a compact height for better ergonomic use.
    [0038] In one embodiment, the set of shelves that subdivide the cooking volume in cooking cavities can provide separate upper and lower air channels divided by at least one inner barrier wall and the barrier wall and jet plate can intercommunicate mechanically by means of a floating support adapted to resist warping of the shelf with variations in the thermal expansion of the barrier wall and the jet plate.
    [0039] And so a feature of at least one embodiment of the invention allows for extremely thin shelves without the risk of disruptive warping caused by oven temperatures. This is particularly important when the jet sheet and barrier walls are of different lengths caused by the intentional inclination of one or the other.
    [0040] In at least one embodiment of the invention, the blowers can communicate with the shelves through a bifurcated collector that provides extended transition sections of smoothly varied cross-section reducing a height of the transition section from an entrance to an exit in no less that 50 percent.
    Petition 870190087795, of 09/06/2019, p. 14/47
    9/30 [0041] It is thus a feature of at least one embodiment of the invention to provide resistance to high airflow and low airflow with extremely narrow high aspect ratio shelf inlets. The introduction of the transition section allows these narrow shelves to receive air with minimized air resistance.
    [0042] The transition sections can simultaneously provide a smoothly varied cross section that increases the width of the transition section from entry to exit by at least 50 percent. It is thus a feature of at least one embodiment of the invention to minimize speed changes in the air flow that could cause turbulence by minimizing variation in the cross-sectional area to the maximum possible.
    [0043] These particular objectives and advantages may apply to only certain modalities that fit the claims, and thus do not define the scope of the invention.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0045] Referring now to Fig. 1, an air dispensing furnace close to multiple zones 10 can provide a housing 12 having vertical insulated external side walls 14a and 14b and a vertical insulated external rear wall 14c which extends between and which joins generally isolated horizontal upper external walls 14d and 14e. The resulting cooking volume 16 is opened at the front and this opening can be covered by hinged door 18 when door 18 is in a closed position, or accessible through hinged door 18 when door 18 is in an open position as it is in general understood in the art. Housing 12 can
    Petition 870190087795, of 09/06/2019, p. 16/47
    11/30 be supported on one or more legs 21 extending downwardly from a base surface of the base wall 14e.
    [0046] Cooking volume 16 can be divided into multiple cooking cavities 20a-d. Although four cooking cavities are shown, the invention contemplates a range of 2 to 6 cooking cavities 20 in vertical spaced separation. Each cooking cavity 20 is separated by a thin shelf 22a-c with shelf 22a separating cavities 20a and 20b, shelf 22b separating cavities 20b and 20c and shelf 22c separating cavities 20b and 20d.
    [0047] Referring also to Fig. 2, each shelf 22 comprises a generally upper and lower rectangular pressure chamber separated 24a and 24b which adjust horizontally in the cooking volume 16. When the shelf 22 is installed, a lower edge the pressure chamber 24b can be supported on rails 26 which extend inwardly from the inner surface of the walls 14a and 14b and the upper pressure chamber 24a can be supported directly over the lower pressure chamber 24b for reduced total height.
    [0048] Each pressure chamber 24 provides an air distribution plate that extends horizontally outside 28 having a set of airflow openings 30 distributed over its area to provide substantially uniform airflow through them. The air distribution plate 28 can be substantially flat and can have one or more reinforcement ribs 29 affixed along its internal surfaces to prevent thermal warping of the opposite edges of the slit-like airflow openings 30 in the air distribution plate 28 as will be described below. The reinforcement ribs 29 can be relatively thin, measured along the length of the airflow openings 30, for example, less than 3.18 mm (1/8 inch) or less than 1.59 mm (1/16 inch) to minimize air interruption through the airflow openings 30.
    Petition 870190087795, of 09/06/2019, p. 17/47
    12/30 [0049] Air enters the side walls of each of the pressure chambers 24a and 24b at the air inlets 32a and 32b, respectively. These air intakes 32 can be as small as 38.1 millimeters (1 1/2 inches) in height and preferably less than 25.4 millimeters (1 inch) in height. From the air inlets 32a and 32b, the air then passes through a horizontally extending channel 34 defined by an internal surface of the air distribution plates 28 and the internal surface of a barrier wall 36 opposite the air distribution plate 28 around the channel 34. The barrier wall 36 has a maximum separation of the air distribution plate 28 at the air inlet 32 and then curves inward towards the air distribution plate 28 as the air conducted in channel 34 escapes. through the airflow openings 30 and lower channel height is required. This slope into the barrier walls 34 for each of the pressure chambers 24a and 24b together provides an additional isolation zone 38 between the barrier walls 36 of the upper and lower pressure chambers 24a and 24b, respectively, minimizing the height of shelf, but maximizing the insulation value. The average separation of the barrier walls 36 can be approximately 25.4 millimeters (one inch) ranging from contact between the barrier walls to nearly 50.8 millimeters (2 inches) of separation. The invention contemplates an average separation of at least 6.35 millimeters (one quarter of an inch) and preferably at least 25.4 millimeters (one inch).
    [0050] A peripheral wall 40 of each pressure chamber 24 surrounds the air distribution plate 28 and the barrier wall 36 to capture air inside the channel 34 in all directions, except through the inlets 32 and the air current openings. air 30. The peripheral wall 40 also provides flaps that extend horizontally inward 43 that can support a wire rack 45 at a separation of approximately 6.35 millimeters (1/4 inch) and at least 3.17
    Petition 870190087795, of 09/06/2019, p. 18/47
    13/30 millimeters (1/8 inch) above the upper extension of the air distribution plate 28 of the upper pressure chamber 24a. In one embodiment, the wire rack 45 can be supported more than 25.4 millimeters (one inch) above the air distribution plate 28 and desirably more than 38.1 millimeters (1.5 inches) above the air distribution plate air both by using a special wire rack 45 and by extension flaps 43 (not shown). In this way, a cooking sheet or pan placed over the shelf 22 rests on the wire rack 45 and does not block the airflow openings 30. In a preferred embodiment, a separation 44 (shown in Figs. 1 and 4) between the upper extension of the airflow openings 30 of the air distribution plate 28 of the upper pressure chamber 24a and the lower extension of the airflow openings 30 of the air distribution plate 28 of the lower pressure chamber 24b will be less than 101.6 millimeters (four inches), preferably less than 76.2 millimeters (three inches) and desirably less than 50.8 millimeters (two inches) providing an extremely compact shelf that maximizes cavity space and minimizes overall height. The cavities 20 (shown in Figs. 1 and 4) will have a nominal height 42 between 101.6 mm and 228.6 mm (four and nine inches) and preferably 127 mm (five inches) or more defined by the distance between distribution plates of air 28 that delimit the upper and lower extension of cavity 20. In a non-limiting example, each cavity can add a height of about 177.8 millimeters (seven inches) to the oven so that three cavities can have a height of no more than 584.2 millimeters (23 inches) or at least no more than 635 millimeters (25 inches), and four cavities can have a nominal height of 762 millimeters (30 inches) and no more than 889 millimeters (35 inches).
    [0051] In general, shelves 22 can be constructed entirely of stainless steel for durability and ease of cleaning, and although
    Petition 870190087795, of 09/06/2019, p. 19/47
    14/30 invention contemplates that thin insulating materials can also be incorporated in the shelves 22, in some embodiments, the invention contemplates that no non-metallic shelf construction material is required. Barrier walls 36 can be maintained within each pressure chamber 24 with a "floating support" allowing sliding of barrier walls 36 with respect to other structures of pressure chambers 24, for example, creating a sliding fit between these enlarged components by a natural flexing of the metal of the barrier walls 36 providing a slight pressure between the barrier walls 36 and the ribs 29 and ferrules extending into the peripheral walls 40. In this way, extremely thin pressure chambers 24 can be developed without warping at high temperature preventing warping forces produced by the barrier walls 36 in the pressure chambers 24 as it is relieved by sliding. This sliding feature can be extended to allow the barrier walls 36 to be removed horizontally through the inlets 32 to eliminate any closed bubbles for easy cleaning of the pressure chambers 24 when removed from the oven 10. Other “floating supports” are contemplated by invention including those providing flexible or spring loaded support that allows relative expansion and contraction rates different from the wide area air distribution plate 28 and barrier walls 36 to prevent warping and distortion of either, or both, or the pressure chamber 24 as it can be particularly critical for extremely thin shelves 22 and pressure chambers 24 at higher temperatures such as above 135 ° C (275 degrees Fahrenheit).
    [0052] Referring now to Fig. 7, each of the cavities 20 can be associated with a temperature sensor 41 that communicates with a controller 47, for example, being a microcontroller having one or more processors 48 that execute programs and that communicate with a
    Petition 870190087795, of 09/06/2019, p. 20/47
    15/30 associated memory 49, maintaining an operational program 51 and several recipe programs 76 as will be discussed in more detail below. Temperature sensors 41 can be thermistors, resistive temperature sensors or the like.
    [0053] Each cavity 20 can also be associated with an airflow system 50 comprising a heater system, blower motor controller and variable speed motor so that controller 47 can independently control the flow of air flowing through of each cavity 20 through a continuous range and can control the temperature of that air in a continuous range of temperatures. The heater system can be, for example, an electric resistance heater such as a "lime" rod controlled by a solid state relay or it can be a heat exchanger for an electrically controllable gas burner system. [0054] Optionally, each cavity 20 can have an electrically controllable valve 52 that communicates with a common water supply 54 (both supplied by a self-contained water source and an external pipe) so that moisture can be introduced into the cavity by a signal to controllable valve 52 from controller 47 to allow independent humidity control according to a cooking program. Mechanisms for introducing controlled humidity into an oven cavity 20 suitable for the present invention are described, for example, in US patents 9,375,021, 7,307,244, 7,282,674 and 6,188,045 assigned to the applicant for this application and by thereby incorporated by reference.
    [0055] Controller 47 can also receive a signal from a door lock sensor 56 (such as a limit switch or proximity switch) and can provide input and output from an oven user via a user interface 58 such such as a touch screen, graphic display, membrane switch or the like as is well known in the art. A data connector 60 can communicate with controller 47 to
    Petition 870190087795, of 09/06/2019, p. 21/47
    16/30 allows you to easily load cooking programs 76 over the Internet or transfer from a portable storage device or the like.
    [0056] One or more of the cavities 20 may also include a smoker 61, for example, providing a compartment that may contain wood chips or the like to be heated by an electrical element controlled by the controller 47 through corresponding solid state relays. The construction of a smoker 61 suitable for the present invention is described, for example, in US patents 7,755,005, 7,317,173 and 7,157,668, each assigned to the depositor of the present invention and hereby incorporated by reference.
    [0057] Referring now to Figs. 3 and 4, the thermal resistance of each shelf 22 will be substantially less than that required to provide thermal insulation for each oven cavity 20 and equal to the insulation between the cooking volume 16 and the kitchen, as provided by the insulation values in the walls 14. For example, walls 14 may have 25.4 millimeters (one inch) of fiberglass mat with a reflective aluminum foil that provides a thermal resistance R value of 3 to 4 (25.4 millimeters material ( one inch) having a K value of approximately 0.04W / mK). Conversely, it is estimated that the effective thermal resistance between the upper and lower channels when separated by an average 25.4 mm (one inch) air gap has an R value of approximately 1 (25.4 mm material [one inch] having a K value of approximately 1.44). In this way, the effective thermal resistance between the upper and lower channels will be less than half that through the outer walls of the oven.
    14. This is the opposite of the existing practice of a multi-cavity oven to make the thermal resistance between the cavities of the oven substantially equal to that between the cavities and the kitchen.
    [0058] Shelves of lower value R 22 provide greater use of the oven cavity and, considerably, height of the oven ergonomically
    Petition 870190087795, of 09/06/2019, p. 22/47
    17/30 improved when multiple cavities are desired and offer an improved ability to remove shelves 22 for cleaning or changing cavity size. However, shelves with a lower R-value provide significant heat transfer between cavities 46, as opposed to normal levels of thermal transfer 46 'insulating the insulation of walls 14. For example, with air at 204.4 ° C (400 degrees Fahrenheit) moving through an upper pressure chamber 24a, the still air from the adjacent lower pressure chamber 24 from an unused cavity 20 below the lower pressure chamber 24 will approach asymptotically temperatures above 148.9 ° C (300 degrees Fahrenheit ) without activating the heater of the unused cavity 20.
    [0059] The present inventors realized that such greater heat transfer can be accommodated through a combination of one or more of: (1) managing cavity temperatures to minimize temperature differences between cavities; (2) ensuring sufficient airflow through the shelves to minimize absolute temperature gain in the air as it passes through the shelves; (3) displacing heat gain and heat loss through separate independent feedback control systems for each cavity; (4) manage airflow to increase thermal resistance for unused cavities; and (5) maximize the separation between air flows on a shelf through the above-described inclined barrier walls. With respect to (2) the problems associated with forced air in increasing heat transfer through low R value shelves can in fact be exploited, as will be described, to manage this heat transfer effectively.
    [0060] Referring now to Fig. 4, as discussed earlier, the airflow system 50 from each cavity 20 (indicated in general by dotted separation lines) may include a separate blower 62 independently controlled by a speed motor variable and
    Petition 870190087795, of 09/06/2019, p. 23/47
    18/30 motor drive 64. Blower 62 may be, for example, a squirrel cage blower and the motor a synchronous DC motor driven by a solid state motor controller of a type known in the art. The use of separate blowers 62 allows total segregation of air flows within each cavity 20. The use of a separate motor and motor drive 64 allows independent air speed control in each cavity 20. [0061] The air flow system air 50 may also include a heater unit 66 and the air from each blower 62 may pass through a heater unit 66 to be received by a bifurcated collector 68 that separates the heated air stream into an upper air stream 70 and stream lower airflow 74. The upper airflow 70 passes into channel 34 (shown in Fig. 2) of a lower pressure chamber 24b of an upper shelf 22 defining an upper wall of cavity 20 and then exits channel 34 as a set of downwardly directed air currents 72a from each of the airflow openings 30 (shown in Fig. 2) distributed in the lower area of the pressure chamber 24b. The lower airflow 74 passes into the upper channel 34 of the upper pressure chamber 24a of a lower shelf 22 defining a lower wall of the cavity 20 to exit channel 34 as a set of upwardly directed air currents 72b from each one of the airflow openings 30 (shown in Fig. 2) distributed in the upper area of the pressure chamber 24a.
    [0062] The bifurcated collector 68 can be designed to provide greater airflow in the upper airflow 70 than the airflow of the lower airflow 74, for example, by restrictions or orientation of the branches of the bifurcated collector 68 with respect to to the natural cyclical flow of the blower. In one example, air can be divided so that 53 to 60 percent of the heated air is allocated to the bottom rack that sends air upward, and 40 to 57 percent of the heated air is allocated to the upper pressure chamber that pulls down as described in US patent application 15 / 016,093
    Petition 870190087795, of 09/06/2019, p. 24/47
    19/30 above.
    [0063] Significantly, the location of the blower outlet 62 is located approximately in the middle of the shelves 22 so that each leg of the collector can provide an aerodynamic reducer / expander 65 approximately 120.6 millimeters (4.75 inches) and at least 76.2 millimeters (three inches) in length to gradually reduce the height of the blower outlet area 62 to the extremely narrow inlet 32 of the pressure chambers 24 and expand its width in the much wider pressure chambers 24. Without this reducer / expander 65, an extremely high air resistance would be generated in an attempt to force air into extremely high aspect ratio pressure chambers 24 in such a way as to resist effective air conduction. For example, each collector 68 can receive air in an area having a height of approximately 101.6 millimeters (four inches) that will be divided into two branches of 50.8 millimeters (2 inches) in height and then smoothly reduced to the high area approximately 25.4 millimeters (one inch) from each pressure chamber
    24. At the same time, the large area of approximately 105.4 millimeters (4.15 inches) in which air is received by the collector 68 can be expanded to the full width of the shelf (approximately 381 millimeters (15 inches) and at least 355 , 6 millimeters (14 inches) through an expander that transitions smoothly Importantly, 90-degree turns to create significant turbulence and counter-resistance are avoided and the change in air speed through the reducer / expander 65 is minimized. the walls of each reducer / expander 65 can be constructed from flat sheets of sheet metal for simplified fabrication and reduced air turbulence.
    [0064] This arrangement of blowers, airflow systems 50 and bifurcated collector 68 is duplicated for each cavity 20. In the uppermost cavity 20a only a single lower pressure chamber 24b is provided at the top of that cavity 20a and in the lower cavity bottom 20d only a single camera
    Petition 870190087795, of 09/06/2019, p. 25/47
    Upper pressure 24a is provided, each being effectively half of the shelf 22.
    [0065] A first element of the active isolation process of the present invention can be understood by considering a cooking program 76 maintained in the memory 49 of the controller 47; cooking program 76 requires a certain time for a Ti cooking cavity control temperature. Initially, the upper air stream dispensed to cavity 20b, for example, can be heated by heater unit 66 to a Ti control temperature through a feedback control structure in which the air temperature in cavity 20b is sensed by sensor 41. A difference between the control temperature Ti and the temperature measured by temperature sensor 41 provides a control signal that controls the heater unit 66, for example, by pulse width modulation. In this control strategy, when the temperature of cavity 20b sensed by sensor 41 rises above the control temperature Ti, heater unit 66 will be deactivated, and, conversely, when the temperature of cavity 20b sensed by sensor 41 falls below the temperature command Τι, the heater can be activated by controller 47. It is noticed that this is a simplified description of feedback control that can provide more sophisticated proportional / integral / derivative control mechanisms as is understood in the additionally modified technique as will be discussed Next.
    [0066] Now consider introducing food into the adjacent upper cavity 20a to cook at a temperature substantially above the control temperature Τι. Heating of cavity 20a results in heat leakage 46 from the upper pressure chamber 24a of the upper shelf 22 to the lower pressure chamber 24b where it heats the airflow 70 to a higher temperature than desired, resulting in air flowing out of the currents of air 72a at a temperature Τι + ΔΤ. The temperature of this air then
    Petition 870190087795, of 09/06/2019, p. 26/47
    21/30 will be sensed by the thermal sensor 41 resulting in a deactivation of the heater unit 66 until the upper airflow 70 of the collector 68 effectively reaches a temperature of Τι-ΔΤ. This cold air at Τι-ΔΤ will then enter channel 34 and an amount ΔΤ will be heated by the heat of leakage. The result is that the draft air 72a will be raised exactly to the desired regulated temperature Ti despite the heat leak.
    [0067] The ability to implement this "active insulation" using a feedback control system requires that the AT component be kept relatively small so that it does not adversely affect the cooking process before a correction can be made. In this regard, the invention employs the movement of air through channel 34 (such that it could otherwise exacerbate the effects of heat leakage between pressure chambers 24) to ensure sufficient airflow velocity through channel 34 of the chamber lower pressure 24b at all times in order to restrict the AT value to a predetermined value that can be easily compensated for by controlling the heater unit 66. Keeping the AT value small by ensuring a certain air speed and thus reduced dwell time of air inside channel 34, the effects of heat leakage can be greatly mitigated.
    [0068] Definitions of the feedback control parameters, for example, in a proportional / integral / derivative controller, can be adjusted using the controller's regulated temperature “knowledge” to estimate heat leakage and adjust the control loop parameters ( integral, proportional and derivative terms) appropriately to ensure proper control loop accuracy. In this way, for example, controller 47 can predict additional thermal loads from leaks by knowing the control temperature profile of adjacent cavities by introducing feed terms ahead between cavities.
    Petition 870190087795, of 09/06/2019, p. 27/47
    22/30
    In addition, or alternatively, each program 76 can be modified according to the knowledge maintained in controller 47 with respect to the temperatures of adjacent cavities.
    [0069] The implementation of the aforementioned active insulation is further complicated by the heat leak 46 through the lower shelf of cavity 20b which, like the heat leak 46 on the upper shelf 22, can be in any direction. Thus, controller 47 has to accommodate the net effect of heat leakage through the upper and lower shelves 22 associated with a given cavity 20. The use of a single properly positioned sensor 41 can automatically implement a control strategy based on a weighted airflow temperature 72a and 72b when compared to the Ti control temperature. Alternatively, multiple sensors 41 can be used to measure airflow temperatures 72a and 72b separately, and signals can be weighted, for example, allowing air currents 72b run somewhere colder or more than the desired cooking temperature.
    [0070] In this regard, it is important that the sensors 41 are placed after the openings and before the heater unit 66. Referring now to Fig. 6, generally a return air passage 80 can be provided on either side left or right of the cavity 20 and / or at the rear of the cavity 20 providing a return air path back to the blower 62 after the air exits through the airflow openings of the air distribution plate 30. The asymmetry in the flow of air by introducing air into the inlets 32 at one end of each shelf 22 and the extraction of air, for example, from the side of the cavity 20 and its rear wall through the return air passage 80 can be compensated by grading the size of the openings airflow 30, for example, to generally increase in size further away from return air hole 82 (from Fig. 4) and return air passage 80 and decrease
    Petition 870190087795, of 09/06/2019, p. 28/47
    23/30 of the hole sizes when moving away from the air inlets 32 as shown to establish a two-dimensional gradient indicated by the arrows 84. In one embodiment, the temperature sensor 41 can be placed in this return air passage 80 to be protected against damage, but monitor excess heat introduced into the air by adjacent cavities.
    [0071] Referring now to Figs. 1 and 5, when a single door 18 is used in oven 10, it can be divided into a set of glass panels 92 separated from each other within a structure having horizontal separating mullions 94 generally aligned with a front edge of each shelf 22. Glass panels 92 can provide at least one layer of insulating air (two separate spaces can be produced using an additional glass panel 92, not shown) that is vertically continuous to allow convection air flow through openings in the base of the door and out of the openings in the top of the door (none shown) to preserve a temperature on the outer surface of the front glass panel 92 for safety. For this purpose, the aisles 94 can provide an air-free passage upwards between the glass panels 92. A malleable gasket or compliant sealing flange 95 can be affixed to the inner surface of the aisles 94 to fill the gap between the front edge of the shelf 22 and the door when door 18 is closed, reducing the flow of air or moisture between cavities 20.
    [0072] Referring now to Figs. 4, 7 and 8, as noted, memory 49 of controller 47 may contain a series of cooking programs 76 (recipes) each providing cooking programs 76 describing cooking parameters as a function of time. Programs 76 can include a humidity program 100, a temperature program 102, and a blower speed program 104. A program similar to humidity program 100 (not shown) can control a smoker characteristic. The blower speed program 104 may include a
    Petition 870190087795, of 09/06/2019, p. 29/47
    24/30 average blower speed 104a (indicated by the dotted line) having an overlapped blower float function 104b, for example, by increasing and decreasing the blower speed in order to break stagnant air patterns in the airflow openings 30 such as what can contribute to uneven heating. By fluctuating the blower speed of the blowers 62, hot spots in the food when the food is stationary with respect to the airflow openings 30 can be further reduced by eliminating the need for transfer systems or rotating platforms on which the food is placed to prevent localized burning of the food, as opposed to a desired uniform cooking.
    [0073] This program information is accessible by controller 47 for all cavities 20 and can be used to accommodate the thermal interaction between cavities 20 (as discussed) and to instruct the user regarding the optimal loading of oven 10. More generally , the program information is used by controller 47 to allow complex changes in temperature, humidity and airflow during cooking adapted to particular recipes. In this regard, the user can identify a recipe, for example, and the cooking of a certain food item in this recipe can be linked to a program developed for that food item without the need for the user to directly program the actual program.
    [0074] Referring now to Fig. 9, the airflow openings 30 in the air distribution plate 28 can provide a series of holes 106 of varying size as discussed in general with respect to Fig. 6 joined by slots 108 Airflow openings 30, comprising both holes 106 and slots 108, create a slit shape that extends the entire width or depth of the furnace (or diagonally between sidewalls of the furnace) as described in the US patent application. 15 / 224,319 referenced above. Overall, a width 110 of the slits 108 will be less than 1.27 millimeter
    Petition 870190087795, of 09/06/2019, p. 30/47
    25/30 (0.05 inch) and preferably less than 2.54 millimeters (0.1 inch) to reduce pressure loss in channel 34 which could result from a high slit area. The holes 106 are much larger than the slot 108 and can be circular and can have a diameter ranging from 7.62 to 15.24 millimeters (0.3 inches to 0.6 inches) to provide air currents that help guide the air of the slits 108 while also minimizing loss of air pressure. Slit lengths can vary between 25.4 to 50.8 millimeters (1 to 2 inches) and are preferably approximately 40.64 millimeters (1.6 inches). The air distribution plate 28 is a thin sheet of metal, for example, stainless steel, less than 3.17 mm (1/8 inch) thick and typically less than 1.59 mm (1/16 inch), as it can be easily formed using laser cutting techniques.
    [0075] Referring now to Fig. 10, the compact shelf arrangement of the present invention is facilitated by the use of a control program that helps to allocate different cooking recipes to the appropriate cavities 20. In this regard, the interface of User 58 can provide graphical indications, for example, by providing an icon 114a-c associated with each of the wells 20a-of arranged vertically in a similar manner to the wells 20. Any particular cooking program 76 that is implemented by a well can be identified , for example, by a recipe tag name 116.
    [0076] In a first case, if no other cavities 20 are being used, the user can enter a new desired recipe (associated with a program 76) in process block 118. For example, the user can indicate a desire to cook bacon slices having a peak cooking temperature of 232.2 ° C (450 degrees Fahrenheit). Using one or more of the peak and average temperature of the identified program 76, an operating program 51 of controller 47 will recommend one or more of the four cavities 20 to the user for placing the desired sliced food item
    Petition 870190087795, of 09/06/2019, p. 31/47
    26/30 bacon. Making this recommendation, operational program 51, in the absence of other item cooking programs, operates to place high temperature recipes in the highest cavities 20 to take advantage of natural temperature gradients established by convective effects, thereby saving power and improving compatibility between possible additional recipes. In one embodiment, programs 76 having an average or peak temperature above 190.55 ° C (375 degrees Fahrenheit) are preferably placed on top or two upper cavities 20a and 20b and this recommendation is imposed by a graying on the user interface 58 of icons 114 for lower cavities 20c and 20d. In contrast, program 76 having an average and peak temperature of less than 162.8 ° C (325 degrees Fahrenheit) is preferably placed in the two bottom or lower cavities 20c and 20d.
    [0077] In a second case, where food is already being cooked, operational program 51 makes cavity loading recommendations based on programs 76 of the food currently being cooked and the new food to be cooked in process block 120. Operational program 51 then recommends a cavity 20 for the new food needed to ensure that the difference in temperature between two adjacent cavities does not exceed the maximum practical temperature difference with the shelves 22 using active insulation. For example, the maximum temperature difference can be 10 ° C (50 degrees Fahrenheit) or another predetermined value, for example, 32.2 ° C (90 degrees Fahrenheit), depending on the characteristics of the oven, and operating program 51 can review each cavity 20 to test whether this maximum temperature difference would be exceeded and, if so, gray these cavities, preventing the user from using them for the new recipe. That way, for example, if bacon slices are being cooked in cavity 20b at 218.3 ° C (425 degrees Fahrenheit) and the new food has to be cooked
    Petition 870190087795, of 09/06/2019, p. 32/47 / 30 cooking temperature of 162.8 ° C (325 degrees Fahrenheit), operating program 51 will require the user to select cavity 20d separated from cavity 20b by cavity 20c. Specifically adjacent icons 114a and 114c can be grayed out as indicated by the block that process 122 to indicate that these cavities 20 are not available and control so that these cavities 20 can be blocked from the user. Instead, a lower cavity 114d is identified for a low temperature cheese pie recipe providing sufficient thermal insulation between cavities associated with the cheese pie.
    [0078] Conversely, if the program temperatures of the new recipe are within the required temperature difference required from adjacent cavities 20, the new food item is placed in a cavity closest to the currently cooking item in order to reduce the use of energy by reducing the temperature difference across the partitioning shelf and thereby transferring heat through the partitioning shelf.
    [0079] Once the appropriate cavity is selected, the user can then press a start button (implemented in user interface 58) detected by decision block 124. As part of this process, the user can confirm that he is using the cavity location recommended by control program 51 in decision block 126. After this confirmation, cooking starts as indicated by process block 128. Failure to confirm the correct cavity provides an error message to the user in process block 130 and allows re-entry of required revenue data.
    [0080] During the cooking process of process block 128, the control system controls the heater, blower, humidity, and smoker as provided by the cooking programs 76 of Fig. 8.
    [0081] When port 18 is opened, for example, and is detected by
    Petition 870190087795, of 09/06/2019, p. 33/47
    28/30 sensor 56, the speed of blowers 62 can be moderated to reduce air leakage through the open door. For example, blowers 62 can be operated at a low level, but a level sufficient for the suction force of the return air in general to prevent heated air from escaping through the open door, and programs 76 can be interrupted to take into account the lost cooking time. As noted here, at all times during cooking food in adjacent cavities 20, a predetermined minimum air flow is provided through channels 34 on shelves 22 to prevent overheating of the air flowing through channels 34 as it could not easily be corrected or compensated using the temperature control system. This air flow can be selected, for example, to ensure that less than an increase of -15 ° C (5 degrees Fahrenheit) in the temperature of the air flowing through the air channel 34 on the basis of knowledge of the surrounding air temperature in the adjacent air channel.
    [0082] Referring again to Fig. 10, the invention contemplates that a complex program for multiple foods cooked at different temperatures having different programs 76 can be fed into control program 51 in process block 118. In this case, program 51 you can have an overview of the entire cooking process for better cooking control. Program 51 can make use of the same compatibility rules described above and knowledge of cooking times to fully program start times and food cavity locations to provide both compatibility of cooking temperatures and simultaneous or programmed ending of each food item. Because the scheduled start times for cooking each food item are known, more sophisticated matching of cavities with recipes can be done by looking not at peak or average cooking temperatures throughout the cooking process, but instead , only
    Petition 870190087795, of 09/06/2019, p. 34/47
    29/30 peak or average cooking temperatures during the period of overlap of the two cavities.
