Detailed Description
Fig. 1 shows a cooking preparation appliance, comprising:
A housing 10 with a front panel 12 forming a human-machine interface 13,
A bowl 20, supported by the casing 10, equipped with a handle 21 elongated by a lateral extension 22 and arranged to receive the food to be prepared,
At least one movable working member (not visible) arranged in the bowl 20 and provided for processing food received in the bowl,
A motor (not visible) housed in the housing 10 and arranged to move the movable working member,
A lid 30 mounted to be removable with respect to the bowl 20 and configured to be in a closed position in which the bowl 20 is closed by the lid 30, as shown in figure 1,
At least one electrical device embedded on the cover 30, here in particular the display device 32.
The bowl 20 may generally be removable relative to the housing 10 for cleaning and additional storage. A quarter-turn (typequartdetour) coupling with bayonet is conceivable, but other types of mounting are also possible (clamping, locking by means of clamps, screwing, etc.). In particular, a resistance heating device can be arranged in the bowl or at its bottom.
The lid 30 may also be generally removable with respect to the bowl 20 for cleaning and additional storage. A quarter-turn coupling with bayonet is conceivable, but other types of mounting are also possible (clamping, locking by means of clamps, screwing, etc.). The lid 30 further includes a lateral projection 31, which lateral projection 31 faces the handle 21 of the bowl 20 when the lid 30 is in the closed position of fig. 1. As best seen in fig. 2, the cover 30 is independent of the housing 10. In other words, the cooking preparation appliance does not have any direct coupling between the cover 30 and the housing 10.
If desired, means for locking the bowl 20 to the housing 10 and/or means for locking the bowl 20 to the housing 10 may be arranged in the housing 10 and/or in the bowl 20.
As such or alternatively, means for locking the lid 30 to the bowl 20 and/or means for locking the lid 30 to the bowl 20 may be arranged in the housing 10 and/or in the bowl 20 (especially at the lateral extension 22), especially during use of the rotating movable working part and/or during or after heating which may cause boiling or spillage.
The movable working member may generally be removable with respect to the bowl 20 so that it may be replaced, cleaned and otherwise stored depending on the preparation to be performed. Specific forms for chopping, cutting, slicing, kneading, mixing, blending, etc. may be provided. A driver at the bottom of the bowl with a male-female coupling with a ball or resilient plunger for effective retention in place is contemplated.
The drive motor is typically housed in the housing 10 below the bowl, for example, a gear motor or a direct drive motor may be used.
The cooking preparation appliance is further 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.
A memory unit may be provided to store instructions, cooking steps or even complete cooking recipes, to enable the control unit to appropriately regulate the cooking preparation appliance according to commands received via the human-machine interface 13.
As described above, the lid 30 is removable with respect to the bowl 20 and includes electrical components. Therefore, the electrical device requires a current supply, and based on the fact that the lid 30 is completely detachable with respect to the cooking preparation appliance and the bowl 20, a current supply compatible with such detachment must be arranged.
For this purpose, it is proposed to arrange a wireless power supply device 40 between the bowl 20 and the lid 30, as shown in fig. 2 and 3. Such a wireless power unit 40 has no connection or mechanical or physical contact between the bowl 20 and the lid 30. In other words, the wireless power unit 40 has no contact traces or connection pads that would ensure physical continuity or material contact between the first power circuit on the bowl 20 side and the second power circuit on the lid 30 side.
In general, the wireless power unit 40 may operate according to electromagnetic principles to generate a current in a receiving coil (integral with the lid 30) and a variable magnetic field formed by a transmitting coil (integral with the bowl 20).
In accordance with the present disclosure and as shown in fig. 2 and 3, the wireless power unit 40 includes a transmitter 41 integral with the bowl 20 and a receiver 42 embedded on the lid 30. Typically, both the transmitter 41 and the receiver 42 include coils to allow wireless powering of the cover 30.
Specifically, the emitter 41 is housed in a shield forming the handle 21, the handle 21 being located in an extension of the lateral extension 22. Thus, the emitter 41 is not visible to the user and is protected from any liquid splatter or mechanical damage.
The receptacle 42 is itself housed in the lateral projection 31 of the cover 30, behind the closing plate 34, the closing plate 34 defining an internal space in the lateral projection 31. As with the emitter 41, the receiver 42 housed in the enclosed space is protected from splatter or mechanical damage that typically occurs during use, handling or cleaning of the components of the cooking preparation.
The display device 32, here provided in the form of a strip extending over the periphery of the cover 30, may comprise a light emitting diode, a liquid crystal display, a light emitting diode display or even a touch screen. All kinds of information can be displayed for the user, that is to say, for example, information about the state of the cooking preparation appliance, its locking, its ability to start or not start the preparation cycle, the type of movable working tool installed or required, whether the cycle is in progress and/or its stage of progression, the set cooking temperature or the temperature of the bowl 20, etc.
For example, the electrical device embedded on the cover 30 may include a lighting device configured to alert a user. In particular, flashing and/or color changing light emitting devices are conceivable.
Further, as shown in FIG. 2, the electrical device may include a motor 33 embedded in the cover 30 that may be used for one or more functions such as moving a fan, vent valve, agitator, vacuum pump, etc. All these possibilities add usage variants and options for enriching the user experience.
It is also possible to arrange sensors, such as temperature sensors, level sensors, filling sensors, etc., in the electrical components of the cover 30. The measurement can also be performed directly in the working or cooking space closed by the cover 30.
Finally, the electrical devices embedded in the cover 30 may include batteries for autonomously powering other embedded electrical appliances, even if the cover 30 is disassembled, or if current peaks are required.
Fig. 3 shows a cross-sectional view of the lateral projection 31 of the lid 30 and the handle 21 of the bowl 20. The emitter 41 is thus housed in an enclosed space below the wall of the handle 21. The receptacle 42 is also housed in the enclosed space defined by the outer wall of the lid 30 and by the closure plate 34.
As shown in fig. 3, the distance between the emitter 41 and the receiver 42 is less than 8mm, preferably 5mm, very preferably 4mm, when the lid 30 is in the closed position. Thus, the magnetic coupling between the transmitter 41 and the receiver 42 can effectively generate a current in the receiver 42.
It may also be arranged that an excitation cycle is regularly initiated in the transmitter 41 to check if the receiver is well in place, which indicates that the cover is in the closed position. In fact, if there is a certain level of reverse reaction current in the emitter 41 after excitation, this indicates that the lid 30 is actually in the closed position, since the receiver 42 is completely within a prescribed distance from the emitter 41.
In short, providing electrical devices in the cover 30 allows for increased and enriched functionality of the cooking preparation appliance. However, since the structure of the cooking preparation appliance is kept simple by the wireless power supply apparatus 40, the wireless power supply apparatus 40 can ensure the supply of electric current to the electric devices embedded in the cover 30 without increasing any special procedure or specific external parts exposed to the user's view or external damage.
It will be understood that various modifications and/or improvements obvious to those skilled in the art may be made to the various embodiments of the utility model described in the present specification without departing from the scope of the utility model.
