Description

Technical Field

[0001] The utility model generally relates to cooking preparation appliances, household cooking preparation appliances, in particular to household cooking preparation appliances equipped with movable working parts (shredders, rotary cutters). During the movement of the movable working parts, users must be prohibited from contacting the movable working parts. Background Art

[0002] Some cooking preparation appliances are known in the prior art. It is known that in these cooking preparation appliances, a bowl supported by a housing is arranged, and a movable working part is placed in the bowl so that the movable working part is driven by a motor to move in the bowl, and generally a removable lid is arranged to keep the bowl in a closed state. During the closed state, the movable working part is driven to move. On the other hand, the lid generally has a large surface and blocks the user's view of the ongoing operation. A display can be provided, such as on the appliances disclosed in documents CN204839070 or CN205458228, but the ergonomics or visibility may not be sufficient to provide a satisfactory user experience.

[0003] Document EP2557970 discloses a cooking preparation appliance that includes a wireless power supply device configured to supply power to electrical devices embedded in the lid. However, this document contemplates selecting an operating program from a plurality of operating programs by rotating the ring of the bowl relative to the base. Such a device only allows for the selection of a very limited number of operating programs. Summary of the Utility Model

[0004] The object of the utility model is to overcome the drawbacks of the above-mentioned prior art documents. In particular, first, a cooking preparation appliance is provided, which includes a bowl supported by a housing, a movable working part in the bowl driven by a motor to move, and a removable lid for closing the bowl. Compared with known appliances, the cooking preparation appliance has improved ergonomics and user experience.

[0005] To this end, a first aspect of the utility model relates to a cooking preparation appliance, which includes:

[0006] - A housing,

[0007] - A bowl, which is supported by the housing and configured to receive food to be prepared,

[0008] - At least one movable working part, which is arranged in the bowl and configured to process the food received in the bowl,

[0009] - A motor, which is accommodated in the housing and configured to move the movable working part,

[0010] - A lid, which is mounted to be removable relative to the bowl body and configured to be in a closed position, in which the bowl body is closed by the lid,

[0011] - At least one electrical device, which is embedded in the lid,

[0012] Characterized in that the cooking preparation appliance includes a wireless power supply device, which is arranged to supply power to the electrical device embedded in the lid.

[0013] According to the above embodiments, the cooking preparation appliance includes an electrical device embedded or integrated in the lid. The electrical device can be a simple indicator light (such as a light-emitting diode), or a more complex device, such as an actuator, a motor, a sensor, a liquid crystal display, a light-emitting diode display, or even a touch screen. Therefore, additional functions are embedded in the lid. This enriches the provided services by increasing the possibilities of recipes, and also improves ergonomics through the information that can be directly displayed on the lid, which is usually the part that is most easily seen by the user, in order to notify the user of such cooking or preparation parameters or steps. In addition, the cooking preparation appliance includes a wireless power supply device (i.e., usually an electromagnetic wave power supply device), so that there is no need for physical electrical contact or wires or plugs or traces between the lid and the rest of the cooking preparation appliance. The lid maintains the appearance of an independent object, which can be installed, disassembled, cleaned or processed without any specific precautions.

[0014] The cooking preparation appliance may include a heating device arranged to heat the bowl body. In particular, the heating device can be supported by a housing or by the bowl body.

[0015] The electrical device can include a measuring device, such as a sensor, for example a temperature sensor or a pressure sensor. Ultrasonic sensors, infrared sensors, laser distance sensors, etc. can also be envisaged.

[0016] The electrical device can include a display device.

[0017] The display device can be arranged to display the cooking temperature setting value.

[0018] The cooking preparation appliance may include a bowl body temperature detector, and the display device is arranged to display the temperature of the bowl body.

[0019] The cooking preparation appliance may include an information storage device arranged to store information of at least one cooking preparation program, and the display device is arranged to display information related to cooking preparation, such as cooking preparation time and / or preparation steps.

[0020] The cooking preparation appliance may include means for locking the lid in the closed position, and the display device is arranged to display information related to the lid locking.

[0021] The cooking preparation appliance may include means for locking the lid in the closed position, and a display device configured to display information related to the locking of the lid.

[0022] According to one embodiment, the wireless power supply device may be an inductive wireless power supply device and may include:

[0023] - A transmitter,

[0024] - A receiver, which is provided in the removable lid. The transmitter and the receiver are typically two complementary parts of an inductive charger, each particularly including an inductor or a coil.

[0025] According to one embodiment, the lid may be configured to reach the closed position by a closing movement, and the receiver may be provided in the lid to reach the coupling position facing the transmitter at the end of the closing movement. The coupling position is the position where the transmitter and the receiver face each other and can interact to supply power to the electrical device. In other words, the coupling position is the position where the magnetic field generated by the transmitter will induce a current in the receiver by induction.

[0026] According to one embodiment, when the lid is in the closed position, the transmitter may be configured to detect that the receiver is in the coupling position. It may be arranged to detect the reaction current in the transmitter generated by the magnetic field induced in the receiver.

[0027] According to one embodiment, the cooking preparation appliance may be configured to send a message indicating that the lid is closed when it detects that the receiver is in the coupling position. Since the coupling position is the result of the closed position of the lid, the detection of the coupling position can be used to inform the user that the lid is in the closed position. For example, an indicator of a specific color on the lid may be lit.

[0028] According to one embodiment, the cooking preparation appliance may be configured to allow the motor to drive the movable working part only when it detects that the receiver is in the coupling position. Since the coupling position is the result of the closed position of the lid, the detection of the coupling position can be used to infer that the lid is in the closed position, which means that the appliance can be used with the movement of the movable working part. This embodiment can be used as a redundant safety feature of another safety device of the appliance.

[0029] According to one embodiment, when the lid is in the closed position, the transmitter may be provided at a distance less than 8 mm from the receiver, preferably less than 5 mm, and very preferably less than 4 mm.

[0030] According to one embodiment, the transmitter may be integrally mounted with the bowl body.

[0031] According to one embodiment, the transmitter may be integrally mounted with the housing.

[0032] According to one embodiment, the transmitter may be disposed in the interior space of the bowl or the housing. Thus, it is invisible to the user.

Ergonomics and user experience are improved.

[0039] According to one embodiment, the electrical device includes a display device, and the cooking preparation appliance may include means for locking the lid in the closed position, and the display device may be configured to display information related to the locking of the lid. Ergonomics and user experience are improved.

[0040] According to one embodiment, the electrical device includes a display device, and the cooking preparation appliance may include means for locking and fixing the lid in the closed position, and the display device may be configured to display information related to the locking and fixing of the lid. Ergonomics and user experience are improved.

[0041] According to one embodiment, the bowl may be mounted removably relative to the housing.

[0042] According to one embodiment, the cooking preparation appliance may include a lid mounting interface, which includes:

[0043] - At least one bayonet mount, which is mounted on one of the lid or the bowl,

[0044] -At least one is configured to receive the reverse form of the bayonet mount, which is mounted on the other of the lid or the bowl body.

[0045] According to one embodiment, the electrical device may include a measuring device, such as a sensor, for example, a temperature sensor. Pressure sensors, ultrasonic sensors, infrared sensors, laser distance sensors, etc. are also conceivable.

[0046] According to one embodiment, the electrical device includes an actuator, such as an electric motor. The actuator or motor housed in the lid can be used for blenders, fans, ingredient dispensers, vacuum pumps, etc. Different types of technologies can be envisaged to achieve motorization: electric motors, micromotors, servo motors, geared motors, electromagnets, etc.

[0047] According to one embodiment, the wireless power supply device may include a switch actuated by the lid and configured to close the power supply circuit (transmitter side or receiver side) of the wireless power supply device only when the lid is in the closed position.

[0048] According to one embodiment, the cooking preparation appliance may include a control unit configured to start a transmitter excitation sequence at regular intervals to measure the reaction current in the transmitter, and the control unit may be configured to allow the operating cycle of the movable working part only when the induced current exceeds a predetermined threshold.

[0049] According to this embodiment, the cooking preparation appliance checks at regular intervals whether the receiver integrated with the lid is still at an appropriate distance from the transmitter, which indicates the closed position. Thus, it can be provided that if the receiver is detected to be too far from the transmitter (in which case the reaction current will be very low or even zero), the appliance is stopped.

[0050] According to one embodiment, the electrical device includes a lighting device configured to warn the user. Description of the Drawings

[0051] Other features and advantages of the present invention will become more apparent by reading the following detailed description of embodiments of the present invention given by way of non-limiting examples and illustrated by the drawings:

[0052] Figure 1 A general perspective view of a cooking preparation appliance is shown, which particularly includes a housing, a bowl body supported by the housing, and a lid for closing the bowl body;

[0053] Figure 2 Shows Figure 1 An exploded view of the cooking preparation appliance at the bowl body and the lid, for particularly showing the wireless power supply device between the bowl body and the lid;

[0054] Figure 3 ShowsFigure 1 Partial cross-sectional view of a cooking preparation appliance at a wireless power supply device, for showing a part of the bowl and the lid. Detailed description of the preferred embodiments

[0055] Figure 1 A cooking preparation appliance is shown, which includes:

[0056] - A housing 10, which has a front panel 12 forming a human-machine interface 13.

[0057] - A bowl 20, which is supported by the housing 10, is equipped with a handle 21 extended by a lateral extension 22, and is arranged to receive the food to be prepared.

[0058] - At least one movable working part (not visible), which is arranged in the bowl 20 and is arranged to process the food received in the bowl.

[0059] - A motor (not visible), which is accommodated in the housing 10 and is arranged to move the movable working part.

[0060] - A lid 30, which is mounted to be removable relative to the bowl 20 and is configured to be in a closed position, in which the bowl 20 is closed by the lid 30, as Figure 1 shown.

[0061] - At least one electrical device, which is embedded on the lid 30, here in particular a display device 32.

[0062] The bowl 20 can generally be removable relative to the housing 10 for cleaning and additional storage. A quarter-turn type coupler with a bayonet can be envisaged, but other types of mounting are also possible (clamping, locking by a clamp, threaded connection, etc.). In particular, a resistive heating device can be arranged in the bowl or at its bottom.

[0063] The lid 30 can generally also be removable relative to the bowl 20 for cleaning and additional storage. A quarter-turn type coupler with a bayonet can be envisaged, but other types of mounting are also possible (clamping, locking by a clamp, threaded connection, etc.). The lid 30 further includes a lateral projection 31, which faces the handle 21 of the bowl 20 when the lid 30 is in Figure 1 the closed position. Figure 2 As can be clearly seen in, the lid 30 is independent of the housing 10. In other words, there is no direct connection between the cooking preparation appliance between the lid 30 and the housing 10.

[0064] If necessary, devices for locking the bowl 20 to the housing 10 and / or devices for locking and fixing the bowl 20 to the housing 10 can be arranged in the housing 10 and / or in the bowl 20.

[0065] Similarly or alternatively, means for locking the lid 30 to the bowl 20 and / or means for locking the lid 30 in a fixed position on the bowl 20 can be arranged in the housing 10 and / or in the bowl 20 (in particular at the lateral extension 22), especially during the use of a rotating movable working part and / or during or after heating that may cause boiling or overflow.

[0066] The movable working part can generally be removable relative to the bowl 20 so that it can be replaced, cleaned and stored separately according to the preparation to be carried out. Specific forms for chopping, cutting, slicing, kneading, mixing, blending, etc. can be provided. A drive can be envisaged at the bottom of the bowl, the drive having a convex-concave connector with a ball or elastic plunger for effectively holding it in place.

[0067] The drive motor is generally housed in the housing 10 below the bowl 20. For example, a reduction motor or a direct drive motor can be used.

[0068] The cooking preparation appliance is also provided with an electrical or electronic control unit for regulating the drive motor and / or the locking means and / or the electrical components of the lid 30.

[0069] A storage unit can be provided to store instructions, cooking steps or even complete cooking recipes so that the control unit can appropriately regulate the cooking preparation appliance according to commands received via the man-machine interface 13.

[0070] As described above, the lid 30 is removable relative to the bowl 20 and includes electrical components. Therefore, the electrical components require a current supply, and based on the fact that the lid 30 is completely removable relative to the cooking preparation appliance and the bowl 20, a current supply compatible with such removal must be arranged.

[0071] For this purpose, it is proposed to arrange a wireless power supply device 40 between the bowl 20 and the lid 30, as Figure 2 and Figure 3 shown. Such a wireless power supply device 40 has no connection or mechanical or physical contactors between the bowl 20 and the lid 30. In other words, the wireless power supply device 40 has no contact traces or connection pads that would ensure physical continuity or material contact between a first power supply circuit on the bowl 20 side and a second power supply circuit on the lid 30 side.

[0072] Generally speaking, the wireless power supply device 40 can operate according to the principles of electromagnetism to generate a current in a receiving coil (integrated with the lid 30) and a variable magnetic field formed by a transmitting coil (integrated with the bowl 20).

[0073] According to the present disclosure and as Figure 2 andFigure 3 As shown, the wireless power supply device 40 includes a transmitter 41 integrated with the bowl body 20 and a receiver 42 embedded in the lid 30. Generally, both the transmitter 41 and the receiver 42 include coils to allow wireless power supply to the lid 30.

[0074] Specifically, the transmitter 41 is housed in a shield forming the handle 21, and the handle 21 is located in an extended portion of the laterally extending portion 22. Thus, the transmitter 41 is invisible to the user and protected from any liquid splashes or mechanical damage.

[0075] The receiver 42 itself is housed in a lateral protrusion 31 of the lid 30, behind a closing plate 34 that defines an internal space in the lateral protrusion 31. Like the transmitter 41, the receiver 42 housed in the enclosed space is protected from splashes or mechanical damage that typically occur during the use, manipulation, or cleaning of the components of the cooking preparation appliance.

[0076] The display device 32, which is provided here in the form of a strip extending around the perimeter of the lid 30, may include light-emitting diodes, a liquid crystal display, a light-emitting diode display, or even a touch screen. It can display all kinds of information for the user, that is, for example, information about the status of the cooking preparation appliance, its locking, its ability to start or not start a preparation cycle, the type of movable working tool installed or required, whether the cycle is in progress and / or its progress stage, the set cooking temperature or the temperature of the bowl body 20, etc.

[0077] For example, the electrical devices embedded in the lid 30 may include lighting devices configured to warn the user. In particular, flashing and / or color-changing lighting devices can be envisioned.

[0078] In addition, as Figure 2 shown, the electrical devices may include a motor 33 embedded in the lid 30, which can be used for one or more functions: moving a fan, a ventilation flap, a stirrer, a vacuum pump, etc. All these possibilities increase the usage variants and options for enriching the user experience.

[0079] Sensors can also be arranged in the electrical devices of the lid 30, such as temperature sensors, liquid level sensors, filling sensors, etc. Measurements can also be made directly in the working or cooking space closed by the lid 30.

[0080] Finally, the electrical devices embedded in the lid 30 may include a battery for autonomously powering other embedded electrical appliances, even if the lid 30 is removed, or if a current peak is required.

[0081] Figure 3A cross-sectional view of the lateral protrusion 31 of the lid 30 and the handle 21 of the bowl body 20 is shown. The transmitter 41 is thus accommodated in a closed space below the wall of the handle 21. The receiver 42 is also accommodated in a closed space defined by the outer wall of the lid 30 and the closed plate 34.

[0082] As Figure 3 shown, when the lid 30 is in the closed position, the distance between the transmitter 41 and the receiver 42 is less than 8 mm, preferably 5 mm, and very preferably 4 mm. Thus, the magnetic coupling between the transmitter 41 and the receiver 42 can effectively generate a current in the receiver 42.

[0083] The transmitter 41 can also be arranged to regularly initiate an excitation cycle to check whether the receiver is properly positioned, which indicates that the lid is in the closed position. In fact, if there is a certain level of reverse reaction current in the transmitter 41 after excitation, this indicates that the lid 30 is actually in the closed position because the receiver 42 is completely within the specified distance from the transmitter 41.

[0084] In short, providing electrical devices in the lid 30 allows the functions of the cooking preparation appliance to be increased and enriched. However, due to the wireless power supply device 40, the structure of the cooking preparation appliance remains simple. The wireless power supply device 40 can ensure the current supply to the electrical devices embedded in the lid 30 without adding any special procedures or specific external components exposed to the user's view or external damage.

[0085] It should be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the various embodiments of the present invention described in this specification without departing from the scope of the present invention.
