[0003] The cooking pot is an important component of the automatic cooking machine, but the existing cooking pot still has the following disadvantages:

[0004] (1) Existing cooking pots are generally heated by electric heating tubes. After electric heating, the electric heating tubes themselves generate heat, and then transfer the heat to the metal surface. The heating area is related to the winding diameter of the heating disk.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (1) This application adopts electromagnetic heating to replace the electric heating tube heating method, optimizes the hollow structure of the electromagnetic heating plate to design a hollow electromagnetic heating plate, and designs the empty distance between the bottom of the round pot liner and the hollow electromagnetic heating plate to ensure the power of the electromagnetic eddy current effect (8-15KW), thereby realizing the concentrated heating of the electromagnetic heating cooking pot.

[0020] (2) The electromagnetic heating plate is a high-temperature resistant plastic part made of PPT material. It is formed by injection molding and has a downwardly concave spherical curved surface. By designing three concentric rings on the electromagnetic heating plate and connecting the three concentric rings together through a radiation connecting piece, a connection structure with a certain strength is formed, which can meet the strength required for coil winding. More importantly, by designing a large area of ​​hollow positions between the various components, it can provide space for heat dissipation for the working coil, enhance the heat dissipation effect, and further improve the electromagnetic eddy current effect.

[0021] (3) The present application makes reasonable use of the space of the hollow electromagnetic heating plate, designs the installation position of the magnetic strip at the bottom of the radiation connecting plate, and effectively accommodates the magnetic core by designing the magnet limit plate and the magnetic strip receiving groove.

[0022] (4) The coil winding method of the present application is multiple.

Each group of coils is independently controlled to be energized or not, and the power of different coils is controlled to achieve control of different gears.

[0023] (5) The heat-insulating bracket of the present application is a heat-insulating quartz sheet, which can effectively prevent heat conduction between the inner tank and the heating plate, thereby increasing the service life of the heating plate.

[0024] (6) In order to enable the entire round pot inner shell to quickly provide the overall temperature, due to the large thermal conductivity of iron, the round pot inner shell is preferably made of an iron pot. The hollow electromagnetic heating plate has high efficiency and is prone to cause local overheating of the iron pot.

DETAILED DESCRIPTION

[0034] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0035] Example 1

[0036] like Figure 1-6 As shown, a high-energy-efficiency electromagnetic heating cooking pot 100 includes a round pot inner liner 2 for cooking, a round pot outer cover 1 for mounting the round pot inner liner 2, and a hollow electromagnetic heating plate 3 for providing heat to the round pot inner liner 2; the round pot inner liner 2 is mounted in the round pot outer cover 1, the hollow electromagnetic heating plate 3 is located below the round pot inner liner 2, a heat insulation bracket 4 is provided at the bottom of the round pot inner liner 2, one end of the heat insulation bracket 4 is fixedly connected to the bottom of the round pot inner liner 2, and the other end is fixedly connected to the hollow electromagnetic heating plate 3, and the empty distance between the bottom of the round pot inner liner 2 and the hollow electromagnetic heating plate 3 is 8-12mm.

[0037] The present application adopts electromagnetic heating to replace the electric heating tube heating method, optimizes the hollow structure of the electromagnetic heating plate to design a hollow electromagnetic heating plate, and designs the empty distance between the bottom of the round pot liner 2 and the hollow electromagnetic heating plate 3 to ensure the power (8-15KW) of the electromagnetic eddy current effect, thereby realizing the concentrated heating of the electromagnetic heating cooking pot. In addition, the hollow electromagnetic heating plate design is conducive to the heat dissipation of the heating plate, maintains the effective diffusion of heat in the cooking pot, is conducive to the automatic control of the temperature of the pot body, and improves the service life of the electromagnetic heating plate. After the cooking pot is powered on, the current passes through the coil wound on the electromagnetic heating plate, generates a changing magnetic field, and generates eddy currents. The round pot liner induces the magnetic field, generates a large amount of heat, and realizes electromagnetic heating.

[0038] As a further preferred embodiment, the hollow electromagnetic heating plate 3 includes a bottom inner ring 31, a middle connecting ring 32, a top outer ring 33, and a radiating connecting piece 34; the bottom inner ring 31, the middle connecting ring 32, and the top outer ring 33 are concentrically arranged at different levels in sequence, and the radiating connecting piece 34 is centered at the center of the bottom inner ring 31 and is radially distributed between the top outer ring 33 and the bottom inner ring 31; an umbrella-shaped hollow position 35 is formed between the bottom inner ring 31, the middle connecting ring 32, the top outer ring 33, and the radiating connecting piece 34. The electromagnetic heating plate is a high-temperature resistant plastic part made of PPT material. Through injection molding, it is in the shape of a spherical curved surface that is concave downward. By designing three concentric rings on the electromagnetic heating plate and connecting the three concentric rings together through the radiating connecting piece 34, a connection structure with a certain strength is formed, which can meet the strength required for coil winding. More importantly, by designing a large area of ​​hollow positions between the components, it can provide heat dissipation space for the coil in operation, enhance the heat dissipation effect, and further improve the electromagnetic eddy current effect.

[0039] As a further preferred solution, the two sides of the bottom of each radiant connecting piece 34 extend downward and then bend to form a magnet limiting piece 36, and the magnet limiting pieces 36 on both sides enclose a magnetic strip receiving groove 37, and a magnetic core (not shown) is installed in the magnetic strip receiving groove 37. The present application reasonably utilizes the space of the hollow electromagnetic heating plate 3, designs the magnetic strip installation position at the bottom of the radiant connecting piece 34, and effectively accommodates the magnetic core by designing the magnet limiting piece 36 and the magnetic strip receiving groove 37.

[0040] As a further preferred embodiment, the upper surfaces of the bottom inner ring 31, the middle connecting ring 32, and the radiating connecting piece 34 are all provided with concentrically arranged annular winding limit plates 38, and an electromagnetic coil (not shown) is installed in the annular winding limit plate. Preferably, a first group of electromagnetic coils is wound inside the bottom inner ring 31, a second group of electromagnetic coils is wound between the middle connecting ring 32 and the bottom inner ring 31, and a third group of electromagnetic coils is wound between the top outer ring 33 and the middle connecting ring 32. Each group of coils is independently controlled to be energized or not, and the power of different coils is controlled to achieve control of different gears. Each group of coils can be composed of a layer of coils, or at least two layers of coils can be stacked, which is used to increase the power of the hollow electromagnetic heating plate 3 to meet the needs of high-power cooking.

[0041] As a further preferred solution, a plurality of wire holes 39 are provided on the hollow electromagnetic heating plate 3 .

[0042] As a further preferred solution, the number of the heat-insulating brackets 4 is multiple, and they are evenly distributed on the bottom periphery of the round pot inner pot 2; each heat-insulating bracket 4 includes an upright connection portion 41, an inclined portion 42 extending outwardly from the upper end of the upright connection portion, and a horizontal portion 43 extending outwardly from the lower end of the upright connection portion, and the inclined portion, the upright connection portion, and the horizontal portion are integrally formed, the inclined portion is fixedly connected to the round pot inner pot 2, and the horizontal portion is fixedly connected to the hollow electromagnetic heating plate 3. The heat-insulating bracket 4 of the present application is a heat-insulating quartz sheet, which can effectively prevent heat conduction between the inner pot and the heating plate, and improve the service life of the heating plate.

[0043] As a further preferred solution, the high-efficiency electromagnetic heating cooking pot 100 further includes a heat-insulating sponge 5 disposed between the round pot liner 2 and the hollow electromagnetic heating plate 3. In order to enable the entire round pot liner 2 to quickly provide the overall temperature, the round pot liner 2 is preferably an iron pot due to the large thermal conductivity of iron. The hollow electromagnetic heating plate 3 has high efficiency and is prone to local overheating of the iron pot. However, in order to prevent the round pot liner 2 from overheating and reversely affecting the working efficiency of the hollow electromagnetic heating plate 3, a heat-insulating sponge is disposed between the round pot liner 2 and the hollow electromagnetic heating plate 3, which can effectively protect the round pot liner 2 and the hollow electromagnetic heating plate 3.

[0044] As a further preferred embodiment, the high-efficiency electromagnetic heating frying pan 100 also includes a cooling fan 6. The side walls of the round pot inner pot 2 and the round pot outer cover 1 are arranged to form a heat dissipation space; the cooling fan is installed at the bottom of the round pot outer cover 1. During the frying process, since the wire coil and the inner pot are installed in a closed space surrounded by the pot body, the heat generated during the frying process accumulates in the inner cavity and is difficult to discharge, which affects the control of the pot body temperature. At the same time, if it works for a long time, the high temperature will also cause the aging of the wire coil. Based on this, the present application further optimizes the heat dissipation structure of the frying pan so that the heat accumulated in the inner cavity can be discharged from the frying pan. This solution accelerates the heat circulation in the enclosed space by designing a cooling fan in the bottom of the pot.

[0045] As a further preferred solution, the round pot cover 1 includes a pot body cover 11 and a pot bottom cover 12 detachably connected to the bottom of the pot body cover 11; the heat dissipation fan is installed at the bottom of the pot bottom cover 12, the bottom surface of the pot bottom cover 12 is provided with a first heat dissipation hole 121, and the upper edge of the pot bottom cover 12 is provided with a second heat dissipation hole 122; the pot body cover 11 is provided with a third heat dissipation hole 111. This solution then designs a variety of heat dissipation holes in the round pot cover 1, each of which is in contact with external air, and can guide the heat in the enclosed space to the outside of the cooking pot through three heat dissipation channels.

[0047] like Figure 7 As shown, a cooking machine 200 includes the high-efficiency electromagnetic heating cooking pot 100 as described in Example 1, as Figure 1-6 The cooking machine also has all the structural advantages of the high-efficiency electromagnetic heating cooking pot in embodiment 1.

[0048] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
