In this way, at the initial stage, the The plurality of second heating devices 22 on the side of the installation cavity 11 all work to heat the side of the pot 200. Since the pot 200 contains food, the food passes through the plurality of second heating devices. 22 When the sides of the pot 200 are heated, the sides of the pot 200 below the food liquid level will heat up slowly, while the sides of the pot 200 above the food liquid level will heat up quickly. The temperature sensor senses the temperature of different areas on the side of the pot body 200, so that the position of the food liquid level can be accurately determined, and the second heating device 22 is controlled to operate at and below the food liquid level, while the second heating device 22 is controlled above the food liquid level. Part of the second heating device 22 stops working. The operation is simple and the control is precise. Since the temperature sensor is an existing technology, it will not be described in detail here.

For example, one edge of the cover 5 is rotatably installed on the base 1, so that the cover 5 can be rotated around the opening. This side edge is flipped to open and close the opening of the mounting cavity 11 . Alternatively, the middle part of the cover 5 can be rotatably mounted on the base 1 through a rotating shaft, so that the cover 5 can rotate around the rotating shaft to open and close the opening of the installation cavity 11 . Alternatively, the cover 5 can move in translation relative to the base 1 , specifically sliding translation or rolling translation, to achieve the purpose of opening and closing the opening of the installation cavity 11 . When the pot 200 is placed in the installation cavity 11 and the cover 5 moves to close the installation cavity 11 , that is, when the opening of the pot 200 is closed, the lid 5 and the pot The open ends of the body 200 are sealed and fit together to form a substantially closed cooking cavity a (refer to FIG. 6 ) (for example, a steam overflow hole may be reserved) to facilitate food cooking.

Therefore, when the base 1 is fixed on any platform, the cover 5 can be placed on the base according to actual needs. 1, for example, it is provided on the top side, any side or even the bottom side of the base 1. However, for ease of understanding, in the embodiments of the present application, the heating base 100 is installed in the up and down direction, that is, in the vertical direction, and the base 1 and the cover 5 are arranged in sequence from bottom to top. The description is given as an example in which the opening of the installation cavity 11 and the opening of the pot body 200 are both facing upward.

In specific applications, the heat conduction plate 232 can be a straight plate-like structure, matching the shape and size of the opening of the pot body 200, so as to just cover the opening of the pot body 200; of course, In other embodiments, at least one side of the heat conduction plate 232 that faces the opening of the installation cavity 11 may be configured in an arc shape with a certain curvature, for example, gradually from the edge of the heat conduction plate 232 to the center of the heat conduction plate 232 . It protrudes toward the base 1 , or extends from the edge of the heat conduction plate 232 to the center of the heat conduction plate 232 in a direction gradually away from the base 1 . Alternatively, the heat conduction plate 232 can be configured in a concave shape, with a plate-shaped main body and a plate-like body.

Specifically, there are many ways to realize that the heat conduction plate 232 is detachably installed in the installation groove 51. For example, the heat conduction plate 232 and the inner wall surface of the installation groove 51 are connected through a buckle structure or a thread. structure, magnetic structure, etc. to achieve detachable connection. Specifically, referring to Figure 3, in the embodiment of the present application, a snap-in groove 511 is formed on the inner wall of the installation slot 51, and the snap-in slot 511 is used for the heat conduction The disk 232 is clamped, so it is easy to process, saves costs, and is simple to operate.

In order to prevent the steam generated during the cooking process from contacting the first induction coil plate 231 and causing the first induction coil plate 231 to rust, the third heating device 23 also includes a sealing ring c, and the sealing ring c is provided on the clamping joint. Between the groove 511 and the heat conduction disk 232, the sealing ring c seals the gap between the snap groove 511 and the heat conduction disk 232, thereby preventing steam from entering into contact with the first induction coil disk 231 and causing the The first induction coil disk 231 is corroded and poses a safety hazard.

Further, the third heating device 23 also includes an insulating partition 233 , which is provided between the first induction coil disk 231 and the heat conduction disk 232 and is connected to the inner wall of the installation slot 51 . , set in this way, the first induction coil disk 231 and the thermal conductive disk 232 are separated by the insulating partition 233. When the thermal conductive disk 232 needs to be repaired, replaced, disassembled and cleaned, the insulating partition 233 can play a good role in isolating and protecting at least the first induction coil disk 231 to prevent the disassembly and assembly process of the heat conduction disk 232 from affecting the use of the first induction coil disk 231 or causing harm to the user.

There are many ways to connect the insulating partition 233 to the inner wall of the installation slot 51 . Specifically, the insulating partition 233 can be directly connected to the inner wall of the installation groove 51 , for example, installed in the installation groove 51 by, for example, welding, screwing, snapping, adhesion or adsorption. on the side wall.

The through hole 52 penetrates the cover 5 , and the through hole 52 can realize material exchange inside and outside the pot body 200 , for example, discharge the steam generated during the cooking process in the pot body 200 to the outside of the pot body 200 , or transfer the pot body 200 to the outside of the pot body 200 . Things outside the body 200 such as food materials are put into the pot body 200 . Therefore, according to the actual needs of cooking, the through hole 52 can be used as a communication hole 52, such as a steam overflow hole in the pot body 200, a feeding hole for materials (such as food ingredients, seasonings, water, etc.), a heat dissipation hole, a pressure relief hole, etc. Kong et al.

Of course, since the through hole 52 communicates with the internal and external environments of the pot body 200, in one embodiment, when the cover 5 also includes functional components, the through hole 52 can also be used as an installation location for the functional components. hole or escape hole.

In one embodiment, the thermometer b is provided at the blind hole 53 . Since the blind hole 53 is semi-closed, it can accumulate more high-temperature steam and prevent the high-temperature steam from flowing outside the pot body 200 . Therefore, disposing the thermometer b at the blind hole 53 has a better and more accurate measurement effect for sensing the temperature changes in the cooking cavity a during the cooking process. Furthermore, the blind hole 53 can be arranged as close to the center of the cover as possible.

Condensed water forms on the side of the inner cavity of the pot body 200 . By setting the inductance of the first induction coil disk 231 to be greater than the inductance of the second induction coil disk, in the energized state, the operating power of the first induction coil disk 231 is greater than the operation power of the second induction coil disk. Power, the first induction coil disk 231 can heat the top of the inner cavity of the pot body 200 to the required temperature more quickly than the second induction coil disk. In addition, because when the lid 5 covers the opening of the pot 200, the lid 5 abuts the upper end of the pot 200, when the first induction coil disk 231 is compared with the second When the induction coil plate is heated to the required temperature faster, the heat can be conducted to the side of the inner cavity of the pot 200 through the contact between the cover 5 and the upper end of the pot 200, assisting the The second induction coil plate heats the side of the inner cavity of the pot body 200 to achieve a better heating effect. Of course, in other embodiments, the inductance of the second induction coil disk can also be set to be greater than the inductance of the first induction coil disk 231 to enhance the heating power of the side of the inner cavity of the pot body 200 so that the pot body The food in the inner cavity of 200 is fully and evenly heated in all directions, which will not be described here.
