Detailed Description

The utility model is further described below with reference to the accompanying drawings.

The IH multi-winding multi-directional heating device comprises a bottom shell 3 and an upper cover 4, wherein the upper cover 4 is covered on the bottom shell 3, a lower coil disc 1 and a tray 5 for being heated by the lower coil disc 1 are arranged in the bottom shell 3, the lower coil disc 1 is arranged on the lower side of the tray 5, an upper coil disc 2 and an inner cover 6 for being heated by the upper coil disc 2 are arranged in the upper cover 4, the upper coil disc 2 is arranged on the upper side of the inner cover 6, the inner cover 6 and the tray 5 enclose a cooking cavity 100 for containing food 99, and the bottom shell 3 is hinged with the upper cover 4, so that the upper cover 4 can be opened to enable the inner cover 6 to be separated from the tray 5, and the cooking cavity 100 can be opened, as shown in fig. 4. The upper coil disc 2 and the lower coil disc 1 may be connected in series or in parallel. The upper side of the inner cover 6 and the outer bottom of the dish 5 can be respectively provided with temperature probes correspondingly.

In the opened state shown in fig. 4, food 99 (for example, steak) is put into the dish 5, and then the upper cover 4 is closed, as shown in fig. 5 and 6, the lower coil disk 1 is energized to generate a high-frequency alternating magnetic field, so that the bottom of the dish 5 generates induced eddy current to generate heat, and similarly, the upper coil disk 2 is energized to generate a high-frequency alternating magnetic field, so that the inner cover 6 generates induced eddy current to generate heat, as shown in fig. 6, so that the inner cover 6 heats the upper surface of the food 99, that is, the inner cover 6 emits heat downwards to heat the food 99, and the bottom of the dish 5 emits heat upwards to heat the lower surface of the food 99, more specifically, when the steak has a certain thickness, the inner cover 6 can be abutted against the upper surface of the steak, and the bottom surface of the steak can be abutted against the bottom of the dish 5. Since the heating device of the present utility model has both upward and downward heating directions, the dish 5 and the inner cover 6 are seen as a single heated device which is heated in both directions, which is advantageous in reducing heat loss and improving heating efficiency as compared with the prior art. Taking the cooking steak as an example, the upper face and the lower face of the steak are heated simultaneously, so that the steak can be uniformly heated, the need of turning the steak to heat is avoided, the cooking time is reduced, and the operation is more single, time-saving and labor-saving; the upper side of the steak is heated and weakened rapidly after the steak is turned over, but because the heat below the steak is transferred upwards, the upper side of the steak is still heated (only weakened much) when the lower side of the steak is heated, and the heated time of the upper part of the steak comprises a high-temperature heating period and a relatively low-temperature heating period, so that the actual heated time of the steak is controlled to have larger uncertainty. Because the upper cover 4 is hinged with the bottom shell 3, the cooking cavity 100 is conveniently opened, so that food 99 can be conveniently taken and placed, and when the upper cover 4 is opened, the upper cover 4 is still connected with the bottom shell 3, so that a user is prevented from needing to find another place to place the upper cover 4, and the operation of closing the upper cover 4 is also simple and convenient. When the upper cover 4 is in a closed state, the upper cover 4 and the bottom shell 3 form a heat insulation structure, so that heat generated by the dish 5 and the inner cover 6 is prevented from escaping to the outside easily.

Further, as shown in fig. 2 and 3, the bottom shell 3 is formed with a bottom shell ear frame 31 at an upper portion thereof, that is, the bottom shell ear frame 31 is protruded outwardly, the upper cover 4 is formed with an upper cover ear frame 41 at a lower portion thereof, and the bottom shell ear frame 31 is connected with the upper cover ear frame 41 through a pin, so that the hinge structure is simple and reliable.

Further, as shown in fig. 2, the inner bottom surface of the dish 5 is formed with the protruding points 501 for contacting the food 99, and the protruding points 501 are distributed on the inner bottom surface of the dish 5, so that the food 99 can be supported by the protruding points 501, thereby avoiding the lower surface of the food 99 from being burnt easily.

Further, as shown in fig. 3 and 4, a lower bump 601 for contacting the food 99 is formed on the lower surface of the inner lid 6, and in the case of cooking steak, the bump 501 contacts the lower surface of the food 99, and the lower bump 601 contacts the upper surface of the food 99, so that the situation that the food 99 is burnt easily due to the overlarge contact area between the steak and the lower surface of the inner lid 6 and the inner bottom surface of the dish 5 is avoided.

As shown in fig. 4, for example, the dish 5, the inner lid 6, the bottom case 3 and the upper lid 4 are all circular.

In some embodiments, as shown in fig. 7 and 8, the tray 5 is a rectangular tray, that is, in a top view, the tray 5 is rectangular, the left side of the tray 5 is provided with a left coil tray 7, the right side of the tray 5 is provided with a right coil tray 8, the front side of the tray 5 is provided with a front coil tray 9, the rear side of the tray 5 is provided with a rear coil tray 10, and the left coil tray 7, the right coil tray 8, the front coil tray 9 and the rear coil tray 10 are all disposed in the bottom case 3. The left coil panel 7, the right coil panel 8, the front coil panel 9 and the rear coil panel 10 are respectively used for heating four side surfaces of the dish 5, and are combined with the lower coil panel 1 and the upper coil panel 2, so that six surfaces of a heating device formed by the dish 5 and the inner cover 6 are heated, the heating effect is further achieved in all directions of food 99, the food 99 is uniformly heated, and the cooking efficiency is further improved. As shown in fig. 9, the form of the rear winding 1001 of the rear coil panel 10 is schematically shown by way of example.

In some embodiments, as shown in fig. 10, the trays 5 are arranged in a horizontal plane, for example, the number of trays 5 is set to four, and the four trays 5 are abutted against each other, that is, the trays 5 are arranged in the longitudinal direction and the lateral direction, respectively. In the present embodiment, the left coil disc 7, the right coil disc 8, the front coil disc 9 and the rear coil disc 10 are provided in the bottom case 3, and the disc 5 is located in a section surrounded by the left coil disc 7, the right coil disc 8, the front coil disc 9 and the rear coil disc 10. So that different foods 99 can be placed in each tray 5, and the taste of the different foods 99 is prevented from being affected by the separation of the trays 5. The left coil panel 7, the right coil panel 8, the front coil panel 9 and the rear coil panel 10 can still heat the food 99 placed in each tray 5 in four directions, namely front, back, left and right, by the heat conduction of the air, the food 99 and the tray 5. The lower coil disc 1, the upper coil disc 2, the left coil disc 7, the right coil disc 8, the front coil disc 9 and the rear coil disc 10 are respectively provided with corresponding windings.

1. The multi-surface heating has the advantages of less heat energy loss, sufficient heating quantity, higher heating efficiency and reduced waiting time.

2. When the device works, the plurality of coil windings are used for respectively heating different surfaces of the heated device, so that the device can be heated simultaneously, independently or alternately and circularly; to ensure uniform heating or to meet individual heating requirements.

3. When the heating appliance needs multi-surface heating, the appliance does not need to be turned over, so that the operation is more simple, time-saving and labor-saving.

4. Under the condition that a plurality of heating appliances (namely a plurality of trays 5 shown in fig. 10) are arranged, the heat which is not absorbed by the tray 5 close to the winding can be supplemented and absorbed by other heating appliances, so that the energy waste is reduced, and the energy conservation and the efficiency are improved.
