Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that embodiments of the invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring embodiments of the present invention.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art.

Hereinafter, a cooking appliance according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings. It can be understood, according to the utility model discloses a cooking utensil can be for electric rice cooker, electric pressure cooker or other cooking utensil, and according to the utility model discloses a cooking utensil except having the function of cooking rice, can also have various functions such as cooking congee, a kind of deep pot hot water, fried dish.

Fig. 1 shows a schematic structural view of a cooking appliance 1 according to a preferred embodiment of the present invention, which mainly includes two parts of a pot body 10 and a heating platform 20 which are separately arranged. The pot body 10 may have a cooking function identical to one or more of cooking appliances such as an electric rice cooker, an electric pressure cooker, an induction cooker, an electric kettle, an electric tea boiler, and the like. The heating stage 20 is provided with a heating means (not shown in fig. 1) to heat the pot body 10.

As shown in fig. 1, the pot body 10 may have a rounded rectangular parallelepiped shape in which the inner pot 12 is disposed. In one embodiment, the pot body 10 has a cylindrical inner pot receiving portion (not shown) therein, and the inner pot 12 can be freely put into or taken out of the inner pot receiving portion to facilitate cleaning of the inner pot 12. The inner pot 12 is generally made of a metal material and has a circular opening on an upper surface for containing a material to be heated, such as rice, soup, etc. Of course, the inner pot 12 may be fixedly provided in the pot body 10 so as not to be removable. The pot body 10 is further provided with a lid body 11. The cover 11 may have a shape substantially corresponding to the pot body 10. The lid body 11 is pivotally connected to the pot body 10 in an openable and closable manner for covering the pot body 10. When the cover 11 is closed on the pot body 10, it covers the inner pot 12 and forms a cooking space with the inner pot 12. Of course, in other embodiments, an open cooking space may be formed in the pot body without providing the lid.

As shown in fig. 2, the heating device 21 is disposed within the heating platform 20. Other components such as a control device 23 are also disposed within the heating platform 20. Thus, by providing the parts in the two portions of the pot body 10 and the heating stage 20, respectively, it is possible to make each portion have a small volume and a small weight. The user only needs to move the pot body 10 after finishing cooking without moving the heating stage 20 together. Therefore, according to the utility model discloses a cooking utensil has light nimble characteristics. Further, it is also possible to provide the heating platform 20 to be adapted to the pot bodies 10 having different cooking functions, reducing the number of cooking appliances in the home.

Since the cooking appliance 1 is constructed in a separate body, the distance interval between the heating means 21 and the inner pot 12 is large. In order to ensure the heating efficiency, the heating device 21 may be configured as an electromagnetic induction heating device. Therefore, in the following description, the heating device 21 may also be referred to as an electromagnetic induction heating device 21. Specifically, the electromagnetic induction heating device 21 may be configured in the form of a coil disk. Accordingly, the inner pan 12 may be configured to be at least partially fabricated from a magnetically conductive heating material. For example, the inner pan 12 may be constructed as a pan wall with an iron base layer, or may have a pan wall of a non-magnetically conductive heating material with a magnetically conductive layer disposed on the pan wall. When cooking is needed, the pot body 10 is placed on the heating platform 20, the electromagnetic induction heating device 21 is powered on and generates a magnetic field, the inner pot 12 generates vortex under the action of the magnetic field, and the food or water in the inner pot 12 is heated by the heat generated by the vortex.

In addition, a metal pan for an induction cooker can also be heated using the heating platform 20 according to the present invention. Due to the different structure of the metal pan and the pot body 10, the heating pattern is different accordingly. Accordingly, different cooking modes for different pots are stored in the control device 23 of the heating platform 20. Therefore, when placing the pan on heating platform 20, need discern the type of pan, then select corresponding culinary art mode according to the recognition result and heat.

As shown in fig. 2, according to the cooking device 1 of the present invention, the magnetic field generating device 13 is disposed in the pot body 10, and accordingly, the magnetic detecting device 22 is disposed in the heating platform 20. The magnetic detection device 22 is electrically connected to the control device 23. When the pot body 10 is placed on the heating stage 20, the magnetic detection means 22 detects the magnetic field generated by the magnetic field generation means 13, and then sends a detection signal to the control means 23. The control means 23 judges that the pot placed on the heating platform 20 at this time is the pot body 10 according to the detection signal, thereby controlling the heating platform 20 to operate in a heating mode suitable for the pot body 10. It will be appreciated that after the heating platform 20 is powered up, if the control means 23 does not receive the detection signal, the control means 23 may default to controlling the heating platform 20 to operate in a heating mode suitable for a metal pan.

In one embodiment, the magnetic field generating means 13 may be constructed as a magnet of a material that is readily available. The magnetic detection device 22 may be configured as a reed switch, and can generate an on-off state change (for example, from on to off or from off to on) under the action of the magnetic field generation device 13. The state change of the on-off state is a detection signal, and the control device 23 judges whether the pot body 10 is placed on the heating platform 20 according to the state change of the reed switch. In order to guarantee the sensitivity that magnetism detection device 22 detected magnetic field generation device 13, according to the utility model discloses, when a kind of deep pot body 10 was placed on heating platform 20, set up distance D between magnetic field generation device 13 and the magnetism detection device 22 and be less than or equal to 20 mm. For example, in various embodiments, 5mm, 7mm, 15mm, etc. may be selected. Preferably, the distance D between the two may be in the range of 2-10mm to further ensure the sensitivity of the detection.

Preferably, the magnetic field generating means 13 may be provided near the bottom of the pot body 10. While within the heating stage 20, the magnetic detection device 22 may preferably be disposed near the top of the heating stage 20. Further, when the pot body 10 is placed on the heating stage 20, the magnetic field generating means 13 and the magnetic detecting means 22 may be at least partially overlapped as viewed in the up-down direction. In this way, the magnetic field generating device 13 can be kept at a short distance from the magnetic detecting device 22.

In addition, when the heating device 21 is an electromagnetic induction heating device, the electromagnetic induction heating device and the magnetic detection device 22 may be disposed at a relatively long distance in order to avoid interference of the magnetic field generated by the electromagnetic induction heating device with the magnetic detection device 22. For example, the magnetic detection device 22 is located outside the electromagnetic induction heating device as viewed in the up-down direction, and the two do not overlap at all. And a magnetic shielding structure capable of shielding the magnetic field, for example, a magnetic shielding sheet constructed of an aluminum plate, may be further disposed between the electromagnetic induction heating device and the magnetic detection device 22 to prevent the magnetic detection device 22 from being in the magnetic field generated by the electromagnetic induction heating device and causing a false detection.

Generally, when the pot body 10 is placed on the heating platform 20, the inner pot 12 can be completely overlapped with the electromagnetic induction heating means as viewed in the up-down direction. That is, the inner pan 12 is completely located within the range of action of the magnetic field generated by the electromagnetic induction heating device to ensure the heating efficiency. However, the magnetic field generating device 13 and the magnetic detecting device 22 need to avoid interference of the magnetic field generated by the electromagnetic induction heating device. Preferably, the position of the magnetic detection device 22 is set properly so that the electromagnetic induction heating device does not overlap the magnetic detection device 22 at all when viewed in the up-down direction in the heating stage 20. That is, the magnetic detection device 22 is located outside the range of action of the magnetic field of the electromagnetic induction heating device acting on the inner pan 12. In the cooker body 10, the position of the magnetic field generating device 13 is reasonably arranged, so that the inner pot 12 and the magnetic field generating device 13 are not overlapped completely when viewed along the up-down direction, thereby avoiding the magnetic field of the electromagnetic induction heating device acting on the inner pot 12 from interfering with the magnetic field of the magnetic field generating device 13.

It can be understood, according to the utility model discloses, can also set up controlling means and magnetism detection device at a kind of deep pot internal, and set up magnetic field generating device in heating platform. Meanwhile, an independent control device is arranged in the heating platform. Therefore, when the cooker body is placed on the heating platform, the magnetic detection device in the cooker body detects the magnetic field and sends a detection signal to the control device in the cooker body, so that the cooker body is judged to be placed on the heating platform. The control device within the pot body may further communicate with the heating platform to send an electrical signal to the control device within the heating platform. At the moment, the cooking process can be flexibly controlled by the control device in the cooker body or the control device in the heating platform according to the requirement. And when the control device in the heating platform does not receive the electric signal, the default is that the pan on the heating platform is a pan, so that the default heating platform works in the mode of an induction cooker.

In this embodiment, the arrangement of the magnetic detection means in the pot body may be similar to that of the above-described embodiment, and the arrangement of the magnetic field generation means in the heating stage may be similar to that of the above-described embodiment.
