Problems solved by technology

[0005] Further, if the thickened pot body is too thick, the heat stored by itself is not conducive to the cooling of the heating pot after stopping or low-power heating, and it is difficult to control the temperature; and after the heating is used, the heavy heating pot is not easy to heat in a short time It emits heat and the pot body is hot, so it is inconvenient to take and clean
[0006] Furthermore, the power of the existing IH electromagnetic heating is generally too large, and most of the power exceeds the traditional heating methods of similar products with the same performance, such as heating plate

Embodiment approach 1

[0042] Implementation method 1: if figure 1 , figure 2 As shown, the coil 20 is placed under the bottom of the thin-walled heating pot 10 , and the bracket 30 connects and fixes the coil 20 and the thin-walled heating pot 10 together.

[0043] Further, the maximum diameter of the coil 20 is smaller than the maximum outer diameter of the bottom of the thin-walled heating pot 10 , and the minimum diameter of the coil 20 is greater than 0.001 times the maximum outer diameter of the bottom of the thin-walled heating pot 10 .

[0044] Furthermore, when the coil 20 generates an alternating magnetic field, the bottom of the thin-walled heating pot 10 corresponding to the coil will generate current to generate self-heating, and this self-heating area is related to the size of the coil, such as Figure 5 As shown, the highest temperature region is larger than the largest diameter A of the coil 20 and smaller than the smallest diameter B of the coil 20 .

[0045] Furthermore, during ...

Embodiment approach 2

[0050] Implementation method 2: if image 3 , Figure 4 As shown, the coil 20 is not only placed under the bottom of the thin-walled heating pot 10, but also placed outside the vertical wall of the thin-walled heating pot 10, and the bracket 30 connects and fixes the coil 20 and the thin-walled heating pot 10 together.

[0051] Further, the coil 20 on the outside of the vertical wall of the thin-walled heating pot 10 and the coil 20 at the bottom of the thin-walled heating pot 10 generate an alternating magnetic field to heat the thin-walled heating pot 10 to achieve the effect of implementing method 1. The outermost layer of the vertical wall of 10 is as Figure 6 A high-temperature region is generated as shown in middle E, and the heat of this part is transferred to the inner wall of the thin-walled heating pot 10 through the thin wall of the thin-walled heating pot 10 for heating food materials.

[0052] Further, there are many thin-walled heating pots 10 in Embodiment 2 ...

Embodiment approach 3

[0054] Implementation method 3: if Figure 7 As shown, the coil 20 is wound in the shape of a spring, and its effect is the same as that of Embodiment 1.

Abstract

An electromagnetic heating structure for rapid heating and cooling of a thin-wall pot body is characterized by mainly comprising a thin-wall heating pot and a coil placed below the bottom of the thin-wall heating pot, wherein the maximum size of the coil is smaller than the size of the bottom of the thin-wall heating pot. The thin-wall heating pot is beneficial to realizing rapid heating and cooling control of an electromagnetic heating thin-wall heating pot, the coil with the maximum size smaller than the size of the pot bottom at the pot bottom of the thin-wall heating pot is beneficial to controlling the highest-temperature area generated when the thin-wall heating pot is electromagnetically heated at the pot bottom, and food materials can be more efficiently heated.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an electromagnetic heating structure for rapid heating and cooling of a thin-walled pot. Background technique [0002] Existing heating equipment for IH automatic cooking machines and IH rice cookers, the coils are arranged according to the shape of the heating pot, not only the coils are arranged at the bottom of the heating pot, but also the coils are arranged outside the vertical wall of the heating pot. [0003] Furthermore, when the coil generates an alternating magnetic field, the heating pot body generates current and self-heats, and the outermost surface of the heating pot body has the largest current, the most heat, and the highest temperature, that is, the outermost layer of the heating pot surrounded by the coil is The highest temperature of electromagnetic induction self-heating; however, the temperature at the bottom of the pot, which is mainly used to h...
