    STOVE FAN OR HOOD, MODULAR COOKER ARRANGEMENT AND METHOD AND ARRANGEMENT FOR OPTIONAL CONNECTION OF THE COOKER TO THE STOVE FAN OR - TO THE COUPLE
    FIELD OF THE INVENTION The invention relates to cooker hoods. In particular, the invention relates to how a cooker hood can be connected to a cooker hood or hood as an optional accessory, as required.
    BACKGROUND OF THE INVENTION A stove guard is a device having sensors with which it measures and detects events in the area of the stove. The cooker guard is a safety device whose function is to react to excessive temperatures and / or other exceptional situations detected by the sensors in a way that aims to reduce or prevent the danger posed by the situation. For example, the stove guard can cut off electricity or other driving power from the stove, trigger the fire extinguisher and / or give an alarm, on the basis of which the user is able to intervene in the course of the threatening situation. The minimum functionalities required for a cooker guard are defined Europe-wide in standard EN 50615. N furniture placement = ta. However, since a cooker fan or hood is often installed above or otherwise in the immediate vicinity of the cooker, it has been found that it would be relatively practical to install at least a portion of the cooker hood with sensors in connection with a cooker hood or hood. For the purposes of this text, a cooker hood means
    with an electric motor equipped with a blower for actively guiding the coils coming from the stove in the desired direction, such as through a flue or through a filter back to the room air. A cooker hood is a device or piece of furniture that tends to passively control the cooker hoods, without a motorized fan. For the sake of brevity, this description will henceforth refer only to a cooker hood, although the term also means a cooker hood, where applicable.
    Manufacturers of range hoods have the same problem as other manufacturers of appliances whose equipment and features may differ depending on the needs. If all cooker hoods were fitted with a built-in cooker hood, the appliance would probably become too expensive for applications where a cooker hood function is not required. If, on the other hand, the manufacturer of cooker hoods separately produces basic models without a cooker hood and more versatile models with a cooker hood, managing the versions of the models to be produced and distributed with their orders, storage and transport is easily twofold.
    SUMMARY OF THE INVENTION It is an object of the present invention to provide a solution by which a manufacturer of cooker hoods = 30 can facilitate the logistics of manufacture and distribution in a situation where some - but only part - of the cooker hoods to be manufactured are equipped with a cooker guard. It is also an object of the invention that it makes it possible, if necessary, to install sludge foam foams, if necessary, in retrofit N 35 objects in which there was initially no such N. In addition, it is an object of the invention to utilize the components of flame fans and cooker guards sensibly so as to avoid unnecessary duplication of structures and solutions.
    The objects of the invention are achieved by providing the cooker hood with a prefabricated installation place to which the cooker hood can be connected as a separate module, and by protecting said installation place in the event that no cooker hood is installed.
    According to a first aspect of the invention, there is provided a modular cooker arrangement having a cooker unit and parts comprising at least an outer shell and a plurality of at least partially interconnected electronic components within the outer shell for arranging the cooker unit to perform cooker functions such as measuring the condition of - comparing the values and / or their development with the decision conditions and giving an alarm and / or switching off the hob in response to an exceptional situation indicated by the comparison.
    The outer shell defines at least a mechanical connection to the master device so that the cooker hood unit can be connected at least mechanically as part of the operating environment of the cooker, such as a cooker hood or hood above or in the immediate vicinity of the cooker.
    The outer shell defines a power supply interface for receiving operating power to the stove guard unit via the master device, and / or the stove guard unit comprises a location for an internal drive power source such as one or more batteries or batteries.
    S 30 According to another aspect, there is provided a modular cooker hood arrangement having a = cooker hood or hood and a prefabricated mounting location for a cooker hood unit for connecting a cooker hood unit as a separate module to a cooker hood or S 35 hood.
    The cooker hood or hood then has N protection arrangements to protect the prefabricated installation site from the ambient conditions of the cooker area and the appropriate
    in a situation where no cooker guard unit is connected to the prefabricated installation site.
    According to an embodiment, the prefabricated installation site includes a drive electrical connector for supplying electrical energy to the liquefaction unit to be installed at the installation site. This has the advantage that versatile functions can be built into the liquefaction unit without having to worry about how much power is used for them.
    According to one embodiment, the protection arrangement has an electrical protection section for protecting the drive electrical connector from unauthorized access. This has the advantage that the appliance is safe to use even when the cooker hood unit is not installed in the cooker hood or hood.
    According to one embodiment, the electrical protection portion comprises a cover or plug covering, removable or movable covering said drive electrical connector. This has the advantage that the appliance is safe to use even when no cooker guard unit is installed in the cooker hood or hood, and nevertheless the installation of the cooker watch unit and the supply of operating electricity to it is straightforward.
    According to an embodiment of the hood, the cooker hood or hood has an arrangement for applying a mains voltage equal to the operating electrical connector to which the hob fan or hood is arranged to be connected for N uses. This has the advantage that the electrical structure of the cooker-N fan or hood can be considered very simple and the electrical interface from it to the N-cooker unit is in accordance with well-known standards. > According to one embodiment, the cooker unit has a power supply connection and a voltage reducer connected thereto for producing a voltage lower than the mains voltage for at least some of the electronic components of the cooker unit received by said cooker unit via said power supply interface. This has the advantage that in the design of the cooker watch unit it is only necessary to set very loose requirements for the electrical interface between it and the master device 5. In addition, the stove guard unit can produce exactly the voltage levels that are needed.
    According to an embodiment of the hood, the cooker hood or hood has a voltage reducer for applying a voltage lower than the mains voltage to the drive electrical connector to which the cooker hood or hood is arranged to be connected for use. This has the advantage that the electronic interface can be easily made to comply with electrical safety regulations.
    According to one embodiment, the voltage reducer is arranged to produce a voltage lower than the mains voltage also for operating at least one electrically driven part included in the cooker hood or hood. This has the advantage that the same voltage reducer can be used for two different purposes, thus saving on component and manufacturing costs.
    According to an embodiment, the prefabricated mounting location is in the form of a recess for receiving a cooker unit to be connected to it completely inside the outer surface delimiting the flame fan or dome. This has the advantage that it is more difficult for an unauthorized person to remove or damage the cooker unit.
    According to an embodiment, the prefabricated S 30 installation site and / or cooker unit includes a Q communication connector for establishing a communication connection between a cooker hood or hood or a corresponding host device and a cooker unit connected thereto. © This has the advantage that the devices can use the information 35 held by each other and, for example, take advantage of each other's user interface features.
    According to one embodiment, the modular cooker arrangement comprises a cooker unit and a cooker hood or hood, the cooker unit being arranged directly or indirectly compatible with a prefabricated installation location in the cooker hood or hood.
    This has the advantage that a natural installation location is available for the cooker unit.
    In addition, the modular arrangement makes it possible to manufacture and sell appliances separately, regardless of where all their applications require a combination of them and where, for example, a mere cooker fan or hood without cooker watch functions is sufficient.
    According to one embodiment, the arrangement includes a mounting frame for fitting the cooker guard unit to a prefabricated mounting location, wherein the cooker guard unit is arranged to be compatible with the mounting frame and the mounting frame is arranged to be compatible with the prefabricated mounting location.
    This has the advantage that the cooker guard unit can be oriented in the best way, regardless of where its installation location is in relation to the area of the cooker to be monitored.
    According to one embodiment, the fitting of the mounting frame to the prefabricated installation site and / or the fitting of the stove guard unit to the mounting frame is interchangeable in at least two different ways so as to result in different orientations of the stove guard unit from the cooker hood or hood.
    This has the advantage of S 30 that only a small number of mechanical parts can be used to make a number of different attachments suitable for different situations. > According to one embodiment, the cooker unit has sensors and a processor connected thereto, the processor 35 being arranged to identify the type of stove in the vicinity of the cooker unit on the basis of the measurement information provided by the sensors.
    This has the advantage that the cooker unit can be easily retrofitted to many different environments and can automatically operate in a suitable manner. According to one embodiment, the processor is arranged to detect, based on the operation of the cooker hood or hood or similar host device, a break in the mains voltage to the cooker hood or hood or a corresponding host device and to prevent at least a temporary heating of the cooker within the range. This has the advantage that the hob does not accidentally start to heat up again after a power failure in a situation where the user is not present.

    DETAILED DESCRIPTION OF THE INVENTION Figures 1 and 2 show the hob 101 and its operating environment, which in this example includes a cooker hood 102 mounted above the hob 101. The hob fans are often mounted directly above the hob, such as installing the cooker hood on the ceiling, on the side of the hob area or on the same table top as the hob. In the latter installation method, the cooker hood may comprise a rising part which rises from the table level to a certain height, for example behind the hob, in order to suck the rises rising from the hob into the filter located behind the hob. In the case of Figures 1 and 2, a modular cooker guard arrangement is used, which will be described in more detail below. It includes a cooker hood unit O 103 which can be installed as part of the cooker hood 102. N With this in mind, the cooker hood 102 has a pre-arranged mounting location 104 for the cooker hood unit 103 N to be connected , it D can perform various stove guard operations as required. For example, it can measure the state of the stove 101 and / or N around it, describe the state it measures as parameter values, and compare these parameter values and / or their development with certain decision conditions. If such a comparison is found to indicate an exceptional situation, the cooker guard unit 103 may give an alarm and / or switch off or limit the operating power of the cooker 101. In these functions, it can be assisted by other units belonging to the same modular cooker guard arrangement, such as a switch unit (not shown in Figures 1 and 2) which is mounted on the hotplate drive connection and is wired or wirelessly controlled by the liquor guard unit 103. . The hob guard unit 103 can also utilize the functions of the hob 101 and / or the hob fan 102, for example, so that the hob is switched off by directly controlling the unit in the hob 101 itself, which is responsible for the internal distribution of operating power.
    The dashed lines 201 and 202 in Fig. 2 show the primary field of view of the cooker unit, i.e. the area in which the cooker unit is most advantageous to measure the condition of the cooker 101 and / or its surroundings. The limits of the primary field of view may be determined by the structure of the cooker unit. In addition to or instead of this, it is possible to construct the cooker unit so that the limits of its primary field of view can be adjusted, for example by orienting the sensors belonging to the cooker unit and / or by moving the optical stops which set the limits of the field of view.
    Fig. 3 shows in more detail an exemplary cooker guard unit 301 and its prefabricated S 30 mounting location 302 in the host device 303, which may be N, for example a cooker hood. In particular, the outer shell of the cooker guard unit 301 is shown in Figure 3, which is a structure that protects and supports other parts of the cooker guard unit 301. © Inside the outer shell there are a number of at least partially interconnected electronic components with which the stove guard unit 301 is made to perform stove guard functions as described above.
    The outer shell of the cooker guard unit 301 defines at least a mechanical connection to the master device 303. Its purpose is thus to connect the cooker guard unit 301 at least mechanically to the operating environment of the cooker, such as a cooker hood above or in the immediate vicinity of the cooker. In the embodiment of Figure 3, the outer shell of the cooker guard unit 301 also defines an electricity supply interface 2304 for receiving operating electricity to the cooker guard unit 301 via the host device 303. In this embodiment, the external shape of the power supply connection 304 is a plug embedded in the outer shell of the cooker guard unit 301, which abuts the mating piece 305 in the prefabricated mounting location 302 when the cooker guard unit 301 is installed. In addition to or instead of the power supply connection 304, the cooker guard unit 301 may have a space 306 for an internal power source such as one or more accumulators or batteries. The use of an internal drive electrical appliance has many advantages, such as the fact that the cooker unit is completely independent of whether it receives electricity from the master appliance or not. Another advantage is that the drive electrical unit and its prefabricated installation site do not necessarily need to be designed and constructed at all, so that the structure becomes simpler and cheaper to implement and the installation of the cooker guard unit in place becomes very straightforward at best. On the other hand, the use of the internal N drive electrical appliance is also associated with fewer N advantageous features, such as the need to change the battery S 30 or recharge the battery and the more limited amount of available electrical energy Q, which in turn can lead to limitations in vin perform.
    S 35 The advantages and disadvantages of a power supply connection such as that shown in Fig. 3 are largely inverse to those of the internal drive electrical equipment described above. The structure becomes somewhat more expensive and complicated to manufacture, and the installation of the cooker unit must take into account the correct fit of the power supply connection at the prefabricated installation site 302. On the other hand, operating electricity can possibly regulating on / off and other switches are. A master device such as a cooker hood is typically permanently connected to the mains, even if its own functions are sometimes switched off. The continuous power consumption of the electronics of the cooker guard unit 301 can typically be made so small that it can utilize the virtually unlimited operating electricity available, for example to make measurements continuously or more frequently, which would only be possible occasionally or less frequently in battery operation. If the cooker guard unit 301 has both a power supply connection 304 and a place 306 for an internal power supply, it can take advantage of both solutions. For example, it can continue to operate with an internal power supply even when no electricity is available via the power supply interface 304, for example due to a power failure or an installation in progress. If the internal power supply is a battery, the cooker guard unit 301 can charge the battery whenever necessary when electricity is available via the power supply connection 304 N.
    Fig. 4 shows in block diagram form a master device 401 and a hotplate unit 402 according to an N embodiments. 401, but in accordance with the principle of modularity, it is not
    for this purpose: if there is no need for cooker watch functions in any operating environment, another module extending the functions of the host device 401, such as an additional light source, a communication module or a camera, can be connected to the module interface 403 to easily share its achievements.
    The host device 401 shown in Figure 4 has a protection arrangement 404 to protect the prefabricated installation site (i.e., the module connection 403) in the area of the stove from environmental conditions and unauthorized access in a situation where no cooker guard unit 402 or other expansion module is connected. The need for a shielding arrangement 404 can be due to a number of reasons. First, it should be noted that environmental conditions in the stove area can often inherently include, for example, grease mist and / or other airborne contaminants that tend to contaminate the surfaces with which they come into contact. Thus, at least one purpose of the shield arrangement 404 may be to protect the prefabricated installation site from contamination. It may include a cover plate that covers the entire module connection 403 when nothing is installed therein. If necessary, the cover plate can be shaped to fit so well with the other design of the host device 401 that the average user may not even notice that the device he is using is “missing”. N Second, if the prefabricated installation site N includes a drive electrical connector 405 for supplying electrical energy S 30 to a cooker guard unit 402 or other function and expansion module to be installed at the prefabricated installation site, electrical safety> must be considered. The shield arrangement 404 may have an electrical shield to protect the drive electrical connector from unauthorized access. In this case, at least one of the purposes of the protection arrangement 404 N may be to prevent unauthorized access, even accidentally, to electrically conductive parts which could have a harmful or dangerous voltage. The electrical shield portion may include, for example, a cover or plug that, in its protective position, covers the drive electrical connector 405 and is removable and / or movable so that it is not (at least unreasonably) in the way when the cooker unit 402 is properly installed. Figure 4 further shows the mechanical attachment 406 as part of the module connection 403 and the corresponding mechanical connection to the master device 407 defined by the outer shell of the cooker guard unit 402. The mechanical attachment 406 at the module connection 403 and the is to keep the cooker guard unit 402 in place and in the correct position when it is connected to the module connection 403. holes. Glue or a sticker can also be used for fastening.
    According to a preferred embodiment, the prefabricated mounting location in the host device 401 is in the form of a recess for receiving a cooker unit to be connected thereto completely inside the outer surface delimiting the cooker hood or hood. From such N so-called. The tamper-proof solution has the advantage that it makes it less likely that any unauthorized person will try to remove the cooker unit. With a view to such attachment, the mechanical connection 407 of the cooker unit 402 may be such that most of the visible surfaces S35 of the outer shell of the cooker unit are shaped and / or finished more simply than is generally required of surfaces visible to the user. If the cooker guard unit 402 is
    the attempt to install in the recess so that most of its surfaces are invisible in any case, there is no need to invest much in the aesthetic design or finishing of these surfaces.
    This can help keep the manufacturing cost of the cooker guard unit 402 reasonable.
    Figure 4 shows the power supply connection 408 as part of the connection 409 of the cooker guard unit 402 to the master device.
    If such an electricity supply interface 408 exists, it can, of course, be used to receive drive electricity to the cooker guard unit 402 via the master device 401.
    The operating electricity is then used to implement the cooker guard functions 410.
    However, it should be remembered that, as described above, the modular cooker arrangement may also be one in which the cooker unit 402 does not have an external power supply connection 408 and / or the host device 401 does not have an operating electrical connector 405, but the cooker unit 402 has battery.
    The host device 401 is typically a mains-operated device, where the mains voltage refers to a single-phase AC voltage or the like of 230 volts or 120 volts (rms) provided by a power distribution network in conventional households or cooking plants.
    Figure 4 shows how the internal power distribution unit 411 of the host device 401 receives the mains voltage and distributes the operating electricity to both the host device's own electrical functions 412 and the operating electrical terminal 405. Based on this, there are several alternative embodiments. In the following, examples will be described with reference to Figures 5 and 6. S 35 In the embodiment of Figure 5, it is assumed that N master devices (such as a cooker hood) have a voltage reducer 501 for a voltage lower than the mains voltage.
    to conduct a connection to said drive electrical connector to which the host device is arranged to be connected for use. Thus, in this embodiment, the cooker guard unit mounted on the module interface receives a substantially lower voltage from the master device than what the master device receives from the electricity distribution network. Electrical safety regulations typically require that the mains electrical connection of the host device include protective components 502, such as fuses, surge protectors, and interference filters. According to the principle shown in Fig. 5, the mains voltage coming through the protective components 502 can be applied to the mains-operated parts of the host device on the one hand and to the voltage reducer 501 on the other hand, which produces one or more voltage levels lower than the mains voltage. The voltage reducer 501 may be arranged to produce one or more voltage levels lower than the mains voltage also for internal use of the master device, i.e. for operating at least one electrically operated part included in the host device but operating at a lower voltage level than the mains voltage. Such lower voltage components inside the host device may be, for example, electronic units, LED lights or the like. In any case, if the master device has a voltage reducer 501 for such needs, one of the lower N voltage levels it produces can be fed to the operating electrical terminal 405 of the module connection, whereby the supply of operating power to the cooker unit is handled .
    > In this specification, "low voltage" means a voltage which is not dangerously high for a person S 35. Definitions of safe low voltage can be found in standards, the best known of which is the SELV standard EN 60335.
    of those Safery Extra Low Voltage, although the letter S has been claimed to also mean the word Separated.
    The advantage of applying a voltage of at most SELV level to the drive electrical terminal 405 is that it is easier to meet the structural and functional requirements of the electrical safety regulations for the module connection 403 of the host device 401 than if a higher voltage is applied to the drive electrical terminal 405.
    Figure 6 shows an alternative embodiment in which the host device has an arrangement for supplying a mains voltage equal to the operating electrical connector to which the host device is arranged to be connected for use.
    Thus, in this embodiment, the cooker guard unit mounted on the module connection receives substantially the same voltage from the master device as it would receive directly from the electricity distribution network.
    The mains electrical connection of the host device may still include protective components 502, but they do not significantly change the voltage level for the needs of the internal parts of the host device as well as the needs of the cooker unit.
    The host device for this purpose can be, for example, a very simple cooker hood representing the most advantageous product range of its manufacturer, which itself does not have any electric parts other than an incandescent lamp, in which case its manufacturer has no motivation to build a voltage reducer.
    Electrical safety regulations may require that there are N protective components 601 on the side of the cooker unit as well. to produce a voltage lower than the mains voltage for at least S35 of the electronic components N of the cooker unit received by the cooker unit via said power supply interface.
    The various conversions between the mains voltage and the voltage levels required by the electronic components are known per se and their detailed implementation is not necessary.
    here.
    Mechanical attachment and transmission of operating electricity are not necessarily the only ways in which the connection between the master and the cooker unit can be utilized.
    Figure 7 shows an embodiment in which both the prefabricated installation site (i.e. module module 403) in the host device and the liquor guard unit include a communication connector 701, 702 for establishing a communication connection between the host device and the cooker guard unit connected thereto.
    Of course, it is also conceivable for embodiments in which this connector is only present in one of the devices - data transfer is then not possible, but either of the devices may itself be initially equipped for a more versatile function than what it is ultimately capable of when installed under conditions.
    The communication connector 701 or 702 may be its own connector based on electrically conductive contact, or it may consist of one or more pins in the same physical connector, which is also used to supply operating power to the cooker unit.
    The communication terminal 701 or 702 may also exist only conceptually (but not physically) as its own N terminal, for example in an embodiment in which the data to be transmitted is modulated as a higher frequency signal on the drive electricity, whereby both the data N and the drive current run exactly the same. = along the roads.
    The communication connector 701 or 702 may also be a non-contact connector, such as an inductive or capacitive communication connection or other short range S 35 wireless communication arrangement.
    The communication connector may exist and may also be used in embodiments where
    the unit does not receive drive power from the master device but operates on an internal drive power unit.
    Thus, an embodiment can be presented in which the cooker unit and the master device have mutually compatible means for implementing a communication interface between them, even if they do not have any arrangement for supplying operating electricity from the master device to the cooker unit.
    If the possibility of data transfer between the cooker unit and the master device exists, it can be utilized in many ways.
    One example is one in which the user interface of the master device is utilized to operate the cooker guard unit.
    For example, assume that the master is a cooker hood and that the cooker guard unit is mounted at the rear of its lower surface, close to the rear wall.
    If, in such a solution, the user would have to reach out every time he presses a button on the cooker unit when, for example, he wants to acknowledge an alarm or otherwise control the operation of the cooker unit, the user could find this inconvenient.
    For small users or those with limited mobility, reaching out to use the cooker hood's own user interface could even be impossible.
    It would be considerably more convenient if the user could make the necessary button presses or other operating operations with the cooker hood's own switches on the front edge of the cooker hood.
    Also, if the cooker hood has a display, the cooker unit N could use it to present information to the user S30, instead of the user having to bend under the cooker hood to see the information on the cooker unit's own display.
    Solutions of this type can be implemented by placing a cooker hood and a cooker guard unit mounted thereon to communicate over a communication interface in a manner for which it is possible for a person skilled in the art to find a suitable practical implementation without further elaboration.
    Figure 8 shows some options for locating the prefabricated installation location of the stove guard unit 103 in the cooker hood 102. The prefabricated mounting position 801 near the front edge of the cooker hood 102 is advantageous in that operation of the cooker easily accessible to the user.
    Even if a communication connection is established between the cooker hood unit and the cooker hood and the user can take advantage of the cooker hood user interface, this location may be advantageous because the construction of connections does not require very long wires within the cooker hood 102 structures.
    On the other hand, many cooker hoods are shaped so that their visible parts closest to the user are as small and scattered as possible, making it difficult to find enough space at the front of the cooker hood, at least for installation in a recess unit 103 completely inside the cooker hood.
    Prefabricated installation location 80 in the middle of the cooker hood 102 it is advantageous in that the field of view of the cooker unit placed therein is relatively easy to cover the entire monitored area on and around the stove.
    N In this case, the differences in distances between the sensors of the cooker unit N and the nearest and farthest point S 30 of the monitored area are also relatively small, which can be useful in making the cooker unit operate = as reliably as possible. are small.
    However, in the middle of the cooker hood S 35 there is often a rather large filter area, from which it can be difficult to find a good place for a prefabricated installation site.
    This location is particularly difficult
    in the case of cooker hoods with a part which can be pulled out from the front edge, because the possibilities of the cooker guard unit to see the area to be monitored undisturbed can vary greatly depending on whether the part in question is pushed in or pulled out.
    A prefabricated installation location 803 at or near the rear edge of the cooker hood is advantageous in that it is often quite easy to find sufficient space in that area to install the cooker guard unit. However, this installation site is associated with the potentially difficult accessibility during use already described above. Of particular importance to the location of the prefabricated installation site may be its design so that the cooker guard unit can be oriented in the best possible direction towards the area it is required to monitor. Figure 9 shows two examples in which the prefabricated mounting location 801 near the front edge of the cooker hood 102 is shaped to orient the cooker unit to be mounted thereon somewhat away from the user (assuming the user's normal position in the area immediately in front of the cooker). Correspondingly, the prefabricated mounting location 803 located at or near the rear edge of the cooker hood is shaped to orient the stove guard unit to be mounted thereon somewhat toward the user. In both examples, it is assumed that the field of view of a cooker unit mounted in a recess N with a substantially rectangular cross-section N extends from the open side of the recess S 30 in a direction whose center line N is perpendicular to the bottom of the recess.
    > The correct orientation of the cooker guard unit can also be © arranged so that - instead of the direct S 35 compatibility discussed above - the cooker guard unit is arranged to be indirectly compatible with the prefabricated installation site. Indirect compatibility
    it appears that the cooker guard unit can be matched to the prefabricated installation site by means of some kind of matching part. Figures 10 and 11 show an illustrative example of this. In the embodiment shown in these figures, the cooker guard unit 103 has a rectangular cross-section. If the prefabricated installation location in the master device such as the cooker hood 102 is already in the correct direction as the installation location 1001 in Fig. 10, the cooker guard unit 103 may be arranged to be directly compatible with the preconfigured installation location. Compatibility here means mechanical compatibility, for example, so that pushing the cooker guard unit deep enough into the recess serving as a prefabricated installation site causes the mechanical connection means in the cooker guard unit to engage the mechanical attachment at the installation site. In the embodiment of Figure 10, the second possible prefabricated mounting location 1002 is in itself parallel to the first, but is located so far at the rear edge of the cooker hood that the field of view of the straight-down watch unit mounted as such would be overweighted at the rear of the hob. The arrangement includes a separate mounting frame 1003 for fitting the cooker guard unit 103 to this rear prefabricated mounting location 1002. The cooker guard unit 103 is arranged to be compatible with the mounting frame N 1003 and the mounting frame 1003 is arranged to be compatible with the prefabricated mounting location N 1002.
    = By using the mounting frame, it is possible to implement even versatile options for orienting the cooker unit ©. Looking at Fig. 10, it is conceivable that S 35 right at the front edge of the cooker hood (i.e., N on the right side of the side view of the cooker hood) could have a prefabricated installation location where the cooker guard unit would be most preferably directed away from the user in the same way as at installation location 801 in Fig. 9. However, this installation location could in itself be directed straight downwards in the same way as the prefabricated installation locations 1001 and 1002. Turning the mounting frame 1003 upside down compared to the position now shown in Fig. 10 would be a sufficient operation for the cooker hood be properly targeted.
    The principle described above can be generalized by characterizing that the fitting of the mounting frame to the prefabricated installation site and / or the fitting of the cooker unit to the mounting frame can be interchanged in at least two different ways so that different ways lead to towards the slurry.
    Figure 12 shows in block diagram form the parts of a cooker unit according to a preferred embodiment, which provide the actual cooker functions.
    The cooker guard unit according to the embodiment of Fig. 12 has sensors 1201 and a processor 1202 connected thereto.
    In practice, N can be implemented in many different ways.
    One example is one in which the sensors 1201 include a sensor that registers N electromagnetic fields.
    Induction hob operation = based on electromagnetic fields that induce> an electric current to the bottom of the cookware, which heats the bottom of the cookware due to the resistance it faces.
    The electromagnetic fields in question are so strong N and so characteristic of their behavior (and also of the simultaneous
    that they can be detected and identified by a sensor included in the liquefaction unit that registers electromagnetic fields.
    In this way, the cooker guard unit can at least identify whether the cooker in its vicinity is an induction cooker or not.
    A similar detection can be made with a microphone, because the use of an induction hob produces a very characteristic, humming sound.
    If the sensors 1201 include a microphone and the processor 1202 is programmed to properly analyze the sound it records, it can detect the presence of an induction hob based on this.
    Another example of identifying the type of stove based on the measurement information provided by the sensors is the use of radiation receivers operating in different wavelength ranges.
    The difference between using a cast iron and a ceramic hob is that the ceramic hob produces easily perceptible visible light at the red end of the spectrum, especially when the switched on ceramic hob does not have a cooking vessel but the cooker unit has a direct line of sight to the hob.
    If the cooker unit has optical sensors operating in suitable wavelength ranges, it can distinguish between ceramic and cast iron stove on this basis.
    Identifying the type of cooker is useful, for example, in a situation where simple cooker hoods have been previously marketed which do not have any cooker guard functions but which nevertheless have N prefabricated mounting locations for the cooker guard unit to be connected as a separate module to the cooker.
    N users who have purchased such a cooker hood may later want to diversify their kitchen and improve the fire safety of their home by purchasing a cooker guard.
    If a flame guard unit such as that described above is subsequently obtained and brought into a pleasant operating environment, it will in principle have no information about the type of stove.
    It would
    however, it is advantageous to be able to identify the type of stove with at least the accuracy of whether it is an induction hob or not, because some stove guard functions are most conveniently performed differently for induction hobs than others.
    In addition to identifying the stove type, other processes that processor 1202 is programmed to perform include, in the embodiment of Figure 12 - processing of measurement data; for example, filtering measurement data and converting it into measured parameter values = responding to commands; starting or stopping various processes or adapting their operation according to the commands given by the user - generating indications; processing the information from the measurement data produced by the sensors alone into, for example, situation data describing the most probable event detected on the stove and / or the most probable value of a measured quantity - measures of alarm situations; for example, issuing an alarm in response to a status report that something in the controlled area is hotter than it should be - adapting to conditions; for example, adjusting alarm limits or otherwise adjusting one's own actions based on how the user has responded to previously issued alarms - power supply control; detecting whether or not N is supplied with mains voltage by the cooker hood or other similar N master.
    As an example of the latter operation, the processor 1202 may be arranged to detect the operation of the cooker hood or similar host device and to detect possible interruptions in the mains voltage received by the cooker fan or the corresponding host device from the electricity distribution network.
    In response to the end of the detected interruption, the processor 1202 may be arranged to prevent
    heating the stove under the influence of the side guard unit at least temporarily. This is based on the idea that the electric stove may have been on at the beginning of the power failure and its operating switches may be mechanical so that at the end of the power failure they reconnect the corresponding hobs to the same power set at the start of the power failure. This should be prevented, as it is not at all certain whether the user will be in front of the stove or even in the whole apartment at the end of the power failure.
    A preferred way to monitor the continuity of the mains voltage (and possibly to implement other types of data transmission between the host device and the liquefaction unit) is shown in Figures 13 and 14.
    As shown in Fig. 13, the prefabricated installation location in the master device is a recess 1301, through a part of which the mains cable 1302 of the host device passes.
    1304. They are connected to the processor of the cooker guard unit, which is able to deduce on the basis of the measurement information provided by the current sensors 1304 when current is flowing at the mains voltage connection of the master device and when it is not, or even how much current is flowing in it.
    The form of data transmission other than controlling the continuity of the mains voltage can be served, for example, by the embodiment N of Figures 13 and 14, in which a host device wishing to communicate some information to the cooker unit is programmed to modulate that information into a higher frequency component. = run for a while at its mains voltage connection. The current sensors 1304 of the flame unit> detect the higher frequency component in question and its variations, from which the processor can read the desired information. N The cooker guard unit itself can detect a power failure even without the system shown in Figures 13 and 14.
    lyä. As an example, a situation can be considered in which the cooker unit receives all its operating electricity from the master device. In this case, the power failure also switches off the cooker guard unit, even if it would normally remain in at least some kind of standby mode, even when the user has switched off the master device. The processor of the cooker guard unit can be programmed so that whenever it starts from complete malfunction, it requires the user to press a button or other acknowledgment before allowing any part of the cooker to heat up.
    In the embodiment of Figure 12, the slag unit further has a user interface connected to the processor 1202, consisting of switches 1203 and indicators 1204, and a memory 1205 in use by the processor, which may store program executed by the processor 1202 and which the processor 1202 may also use to temporarily or permanently store data. to fly. Furthermore, the cooker guard unit has a communication module connected to the processor 1206, via which the processor 1202 can communicate with, for example, a switch unit controlling the stove's power supply and / or a user's portable terminal such as a smartphone. the cooker guard unit is installed in the master device in a place where the switches N 1203 and / or the indicator lights 1204 are awkward. Various modifications, extensions, and combinations of features may be made to the exemplary embodiments described by N F without departing from the scope of the claims set forth below. One example of such a change is the supply of drive electricity from the master device S35 to the cooker unit wirelessly, for example by means of the same N-type inductive energy transfer commonly used in electric toothbrushes. Since
    no galvanic connection is required for the transmission of electrical energy, the protection of the operating electrical connector in the host device is also simple: it can be continuously covered by a protective, insulating layer of material.
