    CULINARY PREPARATION APPARATUS The present invention relates generally to culinary preparation apparatus, and in particular culinary preparation apparatus arranged to heat and automatically work food to be prepared previously placed in a work tank by a user. Typically, the invention relates to a food processor comprising a tank in which the user places ingredients, to then close it with a lid, and the food processor then automatically prepares a dish ready to be eaten, by heating and working the ingredients of the work tank.
    Household robots are known in the prior art, such as that presented in document WO2014 / 026866 A1. On the other hand, the culinary preparation appliance disclosed in this document is complex because it includes a cover which can be blocked on the work tank by longitudinal shafts anchored in a vertical return of the culinary preparation appliance. Consequently, it is necessary to provide a complex and robust chassis (which therefore forms a swan neck), which is expensive and bulky. Consequently, access to the work tank is limited by these lateral blocking members, and the ergonomics of use are limited. Finally, the control of the locking members requires the operation of a geared motor, which is long and can cause waiting on the part of the user.
    An object of the present invention is to respond to the drawbacks of the prior art mentioned above and in particular, first of all, to provide a food preparation appliance (a food processor) with a simple and easy structure use. In addition, the invention provides a
    - 2 process for controlling the culinary preparation device which limits waiting times, while guaranteeing the safety of the user, even if hot food is in the tank.
    For this, a first aspect of the invention relates to a cooking preparation apparatus comprising:
    - a housing,
    - a tank mounted on the housing and arranged to receive food to be prepared,
    - at least one mobile working member arranged in the tank and arranged to work the food received in the tank,
    - a motor arranged in the housing and arranged to set in motion the mobile working member,
    - a removable cover giving the tank a closed state in which the tank is closed by the cover,
    - means for locking the cover on the tank,
    - the cover being arranged to be moved when the tank is in its closed state between:
    - an unlocked position on the tank, in which the cover is released from the locking means, and
    - a locked position on the tank, in which the cover cooperates with the locking means, characterized:
    in that the culinary preparation appliance comprises means for securing the locking of the lid, said means for securing the locking comprising:
    - at least one movable blocking member between a first position in which the movement of the cover from the locked position to the unlocked position is authorized, and a second position in which the blocking member hinders the movement of the cover from the locked position to the
    - 3 unlocked position,
    - a gear motor to move the locking member between the first position and the second position.
    The food preparation appliance according to the above implementation remains simple, since the locked (closed) position of the cover is secured by a blocking member which prevents any relative movement between the tank and the cover, which is likely to allow removal of the cover. The cover cannot be operated to open the tank, and the locking member is a simple member to move, without effort to exert on the cover (since the latter is already coupled and locked with the tank). In summary, during use, the cover is first placed on the tank by the user to close it (the cover is in the unlocked position), then, with the tank still closed, the cover is moved by the user to go into the locked position, and it can then be blocked in this position by the locking securing means (the locking member).
    In other words, the invention relates to a cooking preparation apparatus comprising:
    - a housing,
    - a tank mounted on the housing and arranged to receive food to be prepared,
    - at least one mobile working member arranged in the tank and arranged to work the food received in the tank,
    - a motor arranged in the housing and arranged to set in motion the mobile working member,
    - a removable cover arranged to close the tank,
    - means for locking the cover on the tank,
    - the cover being arranged to be moved, when the tank is closed, between:
    - an unlocked position on the tank, in which the cover is released from the locking means, and
    - a locked position on the tank, in which the cover is locked on the tank by the locking means, characterized:
    in that the culinary preparation appliance comprises means for securing the locking of the lid, said means for securing the locking comprising:
    - at least one movable blocking member between a first position in which the blocking member is released from the cover in the locked position, and a second position in which the blocking member is engaged with the cover in the locked position,
    - a gear motor to move the locking member between the first position and the second position.
    Advantageously, the means for locking the cover on the tank are of the bayonet type. Such locking means are practical and allow a locking action simultaneously with the movement of the cover towards the locked position. It should be noted that the locking means are distinct from the locking securing means. In particular, the cover is moved from its unlocked position to the position locked by the user, to be locked there by a locking member (a bayonet for example). Then only the blocking member of the locking securing means cooperates or engages with the cover to block it. In other words, the blocking member is not part of the locking means.
    Advantageously, the cover is arranged to be moved between the unlocked position and the locked position in a rotational movement relative to the tank. In other words, the cover is mounted on the tank in a pivot connection.
    Advantageously, the tank is removably mounted on the housing and the housing comprises a bearing surface arranged to receive the tank.
    Advantageously, the tank has a handle and the blocking member extends out of the handle when the blocking member occupies the second position. In particular, the blocking member is protruding from the handle only when the blocking member occupies the second position. In the first position, the locking member is advantageously erased relative to the handle, which allows the cover to simply move from the unlocked position to the locked position.
    According to an advantageous embodiment, the blocking member is carried by a rod arranged to be moved by the gearmotor in a translational movement between the first position and the second position, preferably in a sliding connection. In other words, the rod is sliding. In particular, the movement of the rod is substantially parallel to the axis of the movement of rotation of the cover (this axis can also be an axis of symmetry of the tank, and it is vertical, when the food preparation appliance rests on a horizontal plane). In other words, the rod has a blocking portion forming the blocking member. The locking member is therefore perpendicular to a tangential direction of the rotational movement to unlock / remove the cover, which provides effective locking security. Alternatively, the blocking member could in particular be pivotally mounted relative to the tank or relative to the housing. According to an advantageous embodiment, the blocking member is formed by the rod.
    Advantageously then, the gearmotor is coupled to the rod to move the locking member between the first position and the second position. If desired, the gearmotor can in particular be coupled
    - 6 to the rod through a control arm. Alternatively, a transmission device can be arranged between the gearmotor and the rod.
    Advantageously also, the rod is carried by the tank.
    The tank therefore forms a sub-assembly which embeds the rod.
    Advantageously also, the rod is associated with elastic return means arranged to move the rod towards the first position from the second position. The food preparation appliance therefore includes elastic return means, such as a spring to ensure or facilitate the return to the first position of the rod.
    Advantageously also, the tank carries a side cover extending from the bearing surface to an upper part of the tank and the rod is housed mainly between the tank and the side cover.
    Advantageously also, the tank has a handle and the rod locking portion extends out of the handle when the rod occupies the second position. In particular, the rod is protruding from the handle only when it is in second position. In the first position, the rod is obliterated relative to the handle, which allows the cover to simply pass from the unlocked position to the locked position.
    Alternatively, the rod is mounted in slide connection on the housing.
    Advantageously, the blocking member is a male index finger, and the cover comprises a female shape arranged to receive the male index finger.
    Advantageously, the gearmotor is arranged in the housing. Advantageously also, the geared motor comprises a control arm. Advantageously then, the control arm comprises at least one end of travel stop intended to come into abutment with the housing in order to define the first position of the blocking member and / or the second position of the blocking member. If desired the control arm can
    - 7 comprise a first end of travel stop intended to come into abutment with the housing in order to define the first position of the locking member, and a second end of travel stop intended to come into abutment with the housing in order to define the second position of the locking member.
    Advantageously, the gearmotor is arranged to move the locking member from the second position to the first position.
    Advantageously, the mobile working member is a mixer, or a kneader, or a mixer, or a cutting member, or a chopper, or comprises at least one mixing blade, or comprises at least one knife. Typically, such a mobile working member is mobile in rotation inside the tank.
    Advantageously, the culinary preparation device comprises means for detecting the position and / or presence of the tank and / or the cover. This makes it possible to guarantee that the locking of the lid will not be launched until the culinary preparation appliance has recognized that the bowl and the lid are present and coupled together.
    Advantageously, the culinary preparation apparatus comprises heating means arranged to provide cooking heat to the food received in the tank.
    Advantageously, the gearmotor is arranged in the housing.
    Advantageously, the mobile working member is removable.
    A second aspect of the invention relates to a method for controlling a culinary preparation appliance comprising:
    - a housing,
    - a tank mounted on the housing and arranged to receive food to be prepared,
    - at least one mobile working member arranged in the tank and arranged to work the food received in the tank,
    - a motor arranged in the housing and arranged to set in motion the mobile working member according to several working speeds,
    - a removable cover giving the tank a closed state in which the tank is closed by the cover,
    - means for locking the cover on the tank,
    - the cover being arranged to be moved when the tank is in its closed state between:
    - an unlocked position on the tank, in which the cover is released from the locking means, and
    - a locked position on the tank, in which the cover cooperates with the locking means,
    heating means arranged to supply cooking heat to the food received in the tank,
    means for securing the locking of the cover in the locked position, the control method comprising the steps consisting in:
    - automatically actuate the locking securing means when the culinary preparation appliance is started, so as to block the cover in the locked position,
    - activate the locking securing means so as to unlock the cover:
    • simultaneously with a shutdown of the culinary preparation appliance, if a measured temperature of the pan or of the food to be prepared is lower than a predetermined temperature or if a set temperature used before the shutdown of the culinary preparation appliance is lower than a predetermined temperature or if the working speed used before stopping the food preparation appliance is lower than a predetermined speed,
    - 9 • at the end of a rest timer counted down from a stop of the culinary preparation appliance, if a temperature of the tank or of the food to be prepared is higher than the predetermined temperature, and if the speed of work used before stopping the food preparation appliance is greater than a predetermined speed.
    The above method, with the lifting of the securing of the lid locking performed only after the rest time delay if the food is hot and has been vigorously stirred, allows to secure the use. Indeed, the enclosure remains closed and the cover blocked in the locked position if there is a risk of overflow or boiling, after significant heating / stirring. The rest of the time, the cover can be removed immediately after stopping, which limits unnecessary waiting times (because below the predetermined temperature or the predetermined speed, there is no risk of overflow or untimely boiling).
    Advantageously, the temperature of the tank or of the food to be prepared is measured or estimated before or simultaneously at the end of the preparation of the food. In other words, the temperature of the pan or the food to be prepared is estimated or measured at least during the last moments of preparation (in the last minute or in the last thirty seconds or during the last stage of the preparation program cooking) to know whether or not to secure the locking of the cover after the mobile working member and / or the heating means have stopped. The device can include a temperature probe, or take into account the temperature set point used during the cooking preparation program.
    Regarding the working speed, the device can measure or estimate it before or simultaneously at the end of food preparation. In other words, the working speed is estimated or measured at
    - 10 min during the last moments of preparation (in the last minute or in the last thirty seconds or during the last stage of the culinary preparation program) to know whether or not to lock the lid locking after stopping of the mobile working member and / or of the heating means. The device can include an encoder, or take into account the working speed setpoint used during the culinary preparation program. However, the temperature of the pan or the food to be prepared and the working speed are not necessarily estimated or measured at the same time, nor simultaneously.
    A variant of the second aspect of the invention relates to a method for controlling a culinary preparation appliance comprising:
    - a housing,
    - a tank mounted on the housing and arranged to receive food to be prepared,
    - at least one mobile working member arranged in the tank and arranged to work the food received in the tank,
    - a motor arranged in the housing and arranged to set in motion the mobile working member according to several working speeds,
    - a removable cover giving the tank a closed state in which the tank is closed by the cover,
    - means for locking the cover on the tank,
    - the cover being arranged to be moved when the tank is in its closed state between:
    - an unlocked position on the tank, in which the cover is released from the locking means, and
    - a locked position on the tank, in which the cover cooperates with the locking means,
    heating means arranged to supply cooking heat to the food received in the tank,
    means for securing the locking of the cover in the locked position, the control method comprising the steps consisting in:
    - conditionally actuate the locking security means when starting the food preparation appliance, or after starting the food preparation appliance, so as to lock the cover in the locked position, only if a temperature measured from the pan or the food to be prepared is higher than a predetermined temperature or if a set temperature used before stopping the culinary preparation appliance is higher than a predetermined temperature, and if the working speed used is higher than a predetermined speed,
    - actuate the locking security means so as to unlock the cover at the end of a rest time counted from a stop of the food preparation appliance, if the locking security means have been previously actuated so as to lock the cover in the locked position.
    The method according to the above implementation secures the use: the securing of the locked position of the cover is only activated if the food will be strongly heated and stirred during the preparation to come, and it will not be then released only at the end of the rest timer. In all other cases, the cover is not locked in the locked position.
    Advantageously, the temperature of the tank or of the food to be prepared is measured or estimated before or simultaneously at the end of the preparation of the food. In other words, the temperature of the pan or the food to be prepared is estimated or measured at least during the last moments of preparation (in the last minute or in the
    - last 12 30 seconds or during the last stage of the culinary preparation program) to know whether or not to lock the lid locking. The device can include a temperature probe, or take into account the temperature set point used during the cooking preparation program. It is also possible to initiate conditional locking on the basis of the temperature provided for in a future cycle, even before the tank or the food is at this temperature.
    Regarding the working speed, the device can measure or estimate it before or simultaneously at the end of food preparation. In other words, the working speed is estimated or measured at least during the last moments of preparation (in the last minute or in the last thirty seconds or during the last stage of the culinary preparation program) to know if it is necessary to secure or not the locking of the cover. The device can include an encoder, or take into account the working speed setpoint used during the culinary preparation program. It is also possible to initiate conditional locking on the basis of the working speed provided for in a future cycle, even before the mobile working member is put into rotation. However, the temperature of the pan or the food to be prepared and the working speed are not necessarily estimated or measured at the same time, nor simultaneously.
    Advantageously, the duration of the rest time delay is greater than or equal to 5 seconds, and preferably greater than or equal to 10 seconds.
    Advantageously, the predetermined temperature is less than or equal to 60 ° C and preferably less than or equal to 50 ° C, and the predetermined speed corresponds to a speed of rotation of the mobile working member less than or equal to 250 revolutions / min, and preferably less than or equal to 160 revolutions / min.
    Advantageously, the working speed is a set speed to be imposed on the mobile working member during the preset operating program, or the working speed is a measured speed of the mobile working member, at using an encoder for example.
    Advantageously, stopping the food preparation appliance is a stop of the movement of the mobile working member and / or a stop of the heating of the tank.
    Advantageously, the control method comprises, after the start of the culinary preparation apparatus, at least one step consisting in heating the food to be worked and at least one step consisting in working the food to be prepared with the movable member of work.
    Advantageously, the control method comprises, after the start of the culinary preparation apparatus, at least one step consisting of mixing, or kneading, or beating, or cutting, or chopping the food to be prepared.
    Typically, for a food preparation appliance such as that which is the subject of the invention, a speed of rotation of the mobile working member is in a range from 0 to 300 revolutions / min (or revolutions / minute, or min ' 1 ) for example, and preferably between 0 and 200 revolutions / min. Advantageously, the predetermined speed is for example a speed which is in the range of [70% -100%] and preferably [80% 100%] of the maximum speed of the total speed range indicated above. In other words, the locking of the cover is secured for any speed greater than for example 160 rpm and preferably for any speed greater than 250 rpm, if the temperature is greater than 50 ° C or 60 ° C, this which makes it possible to prevent any opening of the working enclosure if a risk of boiling or overflowing is present, even after stopping the engine driving the mobile working member.
    Other features and advantages of the present invention will appear more clearly on reading the detailed description
    - 14 which follows of an embodiment of the invention given by way of nonlimiting example and illustrated by the appended drawings, in which:
    Figure 1 shows an exploded perspective view of a food preparation apparatus according to the present invention comprising a housing, a tank and a cover;
    2 shows a partial section of the food preparation appliance illustrated in FIG. 1, in which the tank is not shown, to show a rod forming part of means for securing a locking of the cover of the appliance for culinary preparation, said rod occupying a first position;
    Figure 3 shows the partial section of Figure 2, with said rod occupying a second position;
    Figures 4a and 4b show a perspective view of a geared motor forming part of the securing means;
    FIG. 5 represents a perspective view of part of the food preparation appliance.
    Figure 1 shows a food preparation appliance with a housing 40, removably receiving a tank 10 which can contain a mobile working member 30 and be closed by a cover 20. The mobile working member 30, here a cutting tool is placed in the tank 10, and is then coupled with a motor located in the housing 40, to be driven in rotation, once the tank 10 is closed with the cover 20.
    The tank 10 has two side covers 11 forming two opposite lateral extensions which go up along the tank 10, and which end in two handles 12 at the top of the tank 10, and each comprising a slot 13 The cover 20 is designed to be mounted on the tank 10 in a rotational movement (a pivot connection is provided), in order to engage a male part of the cover 20 in the slots 13, passing from an unlocked position to a position
    - 15 locked in which the cover 20 is in the final position on the food preparation appliance. This locking system is for example a bayonet lock.
    In other words, the cover 20 in the unlocked position closes the tank 10, and can be removed therefrom freely, but can no longer be lifted from the tank 10 once it has been moved to the locked position, which provides safety in use when the mobile working member 30 is rotating in the tank 10. The bayonet locking means mentioned above can be elastic, that is to say that the user mounting the cover causes the notch to pass a notch so that a flexible tab of the bayonet locking means forms an obstacle to turning back during use. When the preparation is finished, the user by turning the cover 20 in the opposite direction unlocks the bayonet locking means by forcing it to pass the notch again, and can remove the cover 20 by completing the pivoting.
    The culinary preparation apparatus can also include heating means for heating and / or cooking food to be prepared. It is typically a heating resistor placed in the housing 40, on the housing 40, on the tank 10, or in the latter.
    Typically, food to be prepared is placed in the tank 10 with the mobile working member 30, the cover 20 is presented on the tank 10 to close it, then the cover 20 is pivoted to go from the unlocked position to the locked position, and a predetermined preparation program is selected by the user on a control panel 44 of the housing 40. The culinary preparation apparatus may include detection means (presence sensors) which indicate that the tank 10 is in place, and that the cover 20 is in the locked position, before starting the preparation, by heating and / or working the food to be prepared.
    - 16 During this preparation, a speed of rotation of the mobile working member 30 can be imposed in a speed range from 0 to 300 revolutions / min (300 min ' 1 ), in stages, variably or constant. The motor located in the housing 40 is advantageously associated with a reduction gear. The heating means can be chosen to impose on the food to be prepared a temperature of up to 130 ° C. for example.
    Depending on the program selected, and in particular when a risk of hot product overflow is identified, it must be possible to block the cover 20 in the locked position, even if the cover 20 is already locked in the locked position by the means of lock described above.
    Consequently, the culinary preparation device according to the present invention comprises means for securing the locking of the cover 20 in the locked position, highlighted in Figures 2 and 3 which are a partial section of the preparation device culinary along the axis AA of Figure 1.
    The locking securing means include in particular a rod 52 housed in one of the side covers 11 of the tank 10, and a geared motor 51 comprising a control arm 51a, in order to slide the rod 52 relative to the housing 40 and to the tank 10. In the present case, the rod 52 is mounted in slide connection on the tank 10. However, it is possible, as an alternative, to make the rod 52 integral with the housing 40.
    In Figures 1 and 2, the rod 52 is flush with the upper surface of the handle 12, it does not exceed it. The rod 52 is in a first position in which the cover 20 closing the tank 10 can be freely pivoted relative to the tank 10. The locking security means are said to be deactivated.
    - 17 In Figure 3, the rod 52 has been moved upward by the gear motor 51, which makes it protrude by a height d relative to the handle 12, to penetrate the end portion (a portion blocking or engagement) of the rod 52 forming a blocking member 53 in a female form of the cover 20, in order to block the only degree of freedom (rotation) of the cover 20, which is therefore blocked in the locked position. The user cannot pivot the cover 20 to remove it from the tank 10 as long as the rod 52 is in the second position, the locking member 53 impeding the movement of the cover 20. The locking securing means are said to be activated .
    The first position and the second position of the rod 52 forming the locking member 53 may in particular be defined by one or more end stops of the control arm 51a of the geared motor 51, provided for example to come into abutment in the housing 40. As an alternative, it is possible to provide at least one mechanical stop between the rod 52 on the one hand, and the housing 40 or the tank 10 or one of the side covers 11, on the other hand, so as not to exert efforts on the cover 20 in the locked position. However, if the cover 20 is improperly locked and the geared motor 51 still launched, the rod 52 will come into abutment on the cover 20 which is incorrectly positioned.
    In order to return the rod 52 to the first position, it is again necessary to control the gear motor 51 so that the gear motor lowers the control arm 51a, and one can provide a return spring to facilitate the return to position of the rod 52.
    In more detail, Figures 4a and 4b show a view from two points of view of the gear motor 51, which comprises the control arm 51a which comprises a rack 51b, and an electrical connector 51e. The control arm 51a forms a rack and pinion connection with the geared motor 51, and is guided in a sliding connection
    - 18 by the plastic box of the gearmotor 51. The assembly is then compact, and the control arm 51a has two stops 51c and 51 d which are each arranged to come into abutment with a portion of the case 40 to ensure an end stop for the system. The stop 51c provides the upper end of travel stop (rod 52 in second position) and the stop 51 d provides the low end of travel stop (rod 52 in its first position).
    Figure 5 shows a partial perspective view of a part of the food preparation appliance, where we see the gear motor 51 arranged in the housing 40, with the upper part of the control arm 51a which is flush with the housing 40 Thus, when the user couples the tank 10 (with the rod 52 housed in the lateral extension 11) on the housing 40, the rod 52 finds itself facing the control arm 51a, ready to be pushed upwards. the cover 20 must be secured.
    As mentioned above, the locking in the locked position of the cover 20 is only carried out if a risk of overflow of hot product is identified. In particular, the food preparation appliance according to the present invention can implement a control method in which the means for securing the locking of the cover in the locked position are only controlled if a speed of rotation of the mobile working member is greater than a predetermined speed, and if the temperature of the food to be prepared is greater than a predetermined temperature.
    According to a first variant of this method, provision can be made to systematically actuate the locking securing means, so as to always block the cover 20 in the locked position, and hold it during a rest time delay (at least five seconds, and preferably at least eight or ten seconds) the locking securing means activated after stopping, only if during
    - 19 preparation cycle, the speed of rotation of the mobile working member is (or has been) greater than a predetermined speed, and if the temperature of the food to be prepared is (or has been) greater than a predetermined temperature. The user must then wait for the end of the rest time delay before being able to open the cover 20. If these two conditions have not been met simultaneously, the deactivation of the locking security means is simultaneous with the stopping of the food preparation appliance and the user can immediately open the cover 20.
    In other words, according to this variant, the blocking of the cover 20 in the locked position is systematic, and the unlocking is carried out either immediately or simultaneously with the stopping of the culinary preparation appliance if there is no risk of overflow. is identified, or delayed if a risk of overflow is identified (predetermined temperature exceeded and predetermined speed exceeded). In other words, the locking security means are deactivated conditionally.
    According to a second variant of this process, it is possible to block the cover 20 in the locked position only if the two conditions are programmed (that is to say at the start of the food preparation appliance, for example simultaneously at the start of the movement of the mobile working member or even after, but before the speed exceeds the predetermined speed and the temperature exceeds the predetermined temperature), or as soon as these two conditions are measured by the food preparation appliance ( during the program). It is then possible to keep the locking securing means activated during all subsequent use of the culinary preparation appliance, and during a rest time delay (at least five seconds, and preferably at least eight or ten seconds), after complete stop. of the mobile working member and / or of the heating. Thus opening the cover 20 is impossible only when a risk of overflow exists.
    In other words, according to this variant, the locking securing means are activated at startup or during use only if it is planned or measured to exceed the predetermined speed and the predetermined temperature during of the next cycle, and the blocking is maintained for a short time even after the culinary preparation appliance has completely stopped. Provision may be made on the control panel 44 to inform the user whether the opening is possible or not. In other words, the locking securing means are activated conditionally.
    The culinary preparation apparatus therefore comprises a control unit and means for measuring or acquiring the temperature, and means for measuring or acquiring the speed of the mobile working member 30.
    One can use the temperature of the heating means, the temperature of the tank 10, or the temperature of the food to be prepared located in the tank 10. The predetermined temperature can be 50 ° C or preferably 60 ° C.
    With regard to the speed of the mobile working member 30, one can choose to consider that it is necessary to activate the means for securing the locking (if the predetermined temperature is exceeded), as soon as a speed range is chosen or measured (for example the last stage of several pre-programmed speed stages), or as soon as the speed chosen or measured exceeds a particular value, for example 160 rpm or more preferably 250 rpm.
    Thus by blocking the cover 20 in the locked position during the rest time delay, after stopping the stirring and heating of the food, as soon as the speed exceeds the predetermined speed simultaneously with exceeding the predetermined temperature, the opening is impossible as long as there is a risk of accidental overflow and / or boiling.
    - It will be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the various embodiments of the invention described in the present description without departing from the scope of the invention. In particular, reference is made to a male engagement portion of the stem, which engages in a female form of the cover 20, but provision can be made for a movable female engagement portion of the stem, which comes couple with a male index finger of the cover 20.
