Description

Technical Field

[0001] The present invention relates to the technical field of heating, and in particular, to an electromagnetic heating component and an electromagnetic heating device. Background Art

[0002] Electromagnetic heating has become a relatively mature heating technology at the present stage, and it is widely applied to electromagnetic heating devices such as induction cookers.

[0003] Among them, the working principle of the electromagnetic heating coil is as Figure 1 shown. After the electromagnetic heating coil is powered on, it will form a magnetic field provider with one end being the N pole and the other end being the S pole by itself. The magnetic force lines emitted from the N pole will pass through space and return to the S pole, thus forming a magnetic field. When the cookware is located in the magnetic field formed by the electromagnetic heating coil, eddy currents can be generated in the cookware itself, thereby generating heat. In order to enable the cookware to have a larger heating area and reduce the influence of the magnetic field on the interior of the device, it is necessary to make the magnetic force lines emitted from the N pole rise upward, and the magnetic force lines of the S pole are inhibited from rising upward, that is, the rising height of the magnetic force lines emitted from the N pole should be higher than the rising height of the magnetic force lines returning to the S pole.

[0004] As Figure 2 and Figure 3 shown, when the electromagnetic heating coil is actually used, the electromagnetic heating coil 202' needs to be assembled onto the bracket 204', and the bracket 204' is fixed to the base 206' by screws to achieve heating of the cookware 208'.

[0005] Among them, the magnetic field generated by the electromagnetic heating coil has a heating distance, and this heating distance is positively correlated with the rising height of the magnetic force lines emitted from the N pole. As Figure 2 known, the electromagnetic heating coil 202' is divided into two concentrically arranged coils. Although the two concentrically arranged coils can increase the rising height of the magnetic force lines emitted from the N pole, the increase is limited and can be ignored. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0007] To this end, the first aspect of the present invention is to provide an electromagnetic heating component.

[0008] The second aspect of the present invention is to provide an electromagnetic heating device.

[0009] In view of this, according to the first aspect of the present invention, the present invention provides an electromagnetic heating component, including: a bracket; a first electromagnetic heating coil provided on the bracket; M second electromagnetic heating coils provided on the bracket and distributed at intervals along the circumferential direction of the first electromagnetic heating coil, with the first end of each second electromagnetic heating coil close to the first electromagnetic heating coil and the second end of each second electromagnetic heating coil far from the first electromagnetic heating coil, where M is a positive integer; wherein, the first end and the second end are the two ends in the direction of the wire lamination of the second electromagnetic heating coil.

[0010] The technical solution of the present invention proposes an electromagnetic heating component. In the above electromagnetic heating component, the N pole formed by the energized second electromagnetic heating coil will be close to the N pole formed by the energized first electromagnetic heating coil. In the case where the N poles are close to each other, the two will form a repulsive force. Under the action of the above repulsive force, the magnetic lines of force around the N pole of the first electromagnetic heating coil and the magnetic lines of force around the N pole of the second electromagnetic heating coil will rise. The rising magnetic lines of force will form a closed curve with the S pole of the second electromagnetic heating coil.

[0011] In this process, compared with the related technical solutions, it is possible to increase the rising distance of the magnetic lines of force, thereby increasing the heating distance. At the same time, the magnetic lines of force formed by the N pole of the second electromagnetic heating coil also rise synchronously. Therefore, compared with the related technical solutions, the electromagnetic heating component proposed by the present invention can also increase the magnetic field intensity and the coverage range of the magnetic field, so that the sides of more cookware are also within the coverage range of the magnetic field. On this basis, the area where eddy currents appear in the cookware also increases synchronously, realizing three-dimensional heating of the food materials, thereby improving the heating effect. It improves the probability of the situation that the cookware stops heating due to being far from the first electromagnetic heating coil in the scenario of flipping the pan. Since the first end of the second electromagnetic heating coil is close to the first electromagnetic heating coil, the second end of the second electromagnetic heating coil is far from the first electromagnetic heating coil, and the M second electromagnetic heating coils are distributed at intervals along the circumferential direction of the first electromagnetic heating coil. Therefore, the second electromagnetic heating coil and the first electromagnetic heating coil will form an installation state with one vertical and one horizontal.

[0012] When the first electromagnetic heating coil is energized, an N pole can be formed at one end of the first electromagnetic heating coil and an S pole at the other end. After the second electromagnetic heating coil is energized, it will also form a magnet with one end as the N pole and the other end as the S pole, achieving the effect of increasing the rising distance of the magnetic lines of force as described above.

[0013] In some technical solutions, the direction of the wire lamination of the first electromagnetic heating coil can be understood as that in the axial direction of the winding of the first electromagnetic heating coil, the definition of the direction of the wire lamination of the second electromagnetic heating coil is the same as that of the first electromagnetic heating coil, and details will not be elaborated here.

[0014] In some technical solutions, the direction in which the wire layers of the first electromagnetic heating coil are stacked can be understood as the direction from the S pole to the N pole of the first electromagnetic heating coil. Similarly, the definition of the direction in which the wire layers of the second electromagnetic heating coil are stacked is the same as that of the first electromagnetic heating coil, and will not be elaborated here.

[0015] In addition, the electromagnetic heating assembly proposed by the present invention also has the following additional technical features.

[0016] In some technical solutions, the bracket includes: an installation barrel for accommodating the first electromagnetic heating coil, and the axis of the installation barrel is parallel to the direction in which the wires of the first electromagnetic heating coil are stacked; M installation parts are distributed at intervals along the circumferential direction of the installation barrel and correspond one-to-one to the M second electromagnetic heating coils, and the second electromagnetic heating coils are sleeved on the installation parts.

[0017] In this technical solution, by providing the installation barrel, the first electromagnetic heating coil can be directly assembled into the installation barrel to reduce the assembly difficulty of the first electromagnetic heating coil, and the provided installation parts facilitate directly winding the second electromagnetic heating coil on the installation parts. During this process, since the relative position relationship between the installation barrel and the installation parts is fixed, the assembly difficulty of the first electromagnetic heating coil and the second electromagnetic heating coil can be reduced, and the assembly efficiency can be improved.

[0018] In some technical solutions, optionally, the connection line between the first end and the second end of the installation part corresponds to the first connection direction, and the position on the installation barrel connected to the first end of the installation part has a first radial direction; wherein, the angle between the first connection direction and the first radial direction is greater than or equal to 0°.

[0019] In this technical solution, the angle between the first connection direction and the first radial direction being greater than or equal to 0° can be understood as the angle between the first connection direction and the first radial direction being equal to 0° or the angle between the first connection direction and the first radial direction being greater than 0°.

[0020] Among them, the first radial direction can be understood as the connection line direction between the axis of the installation barrel and the position on the installation barrel connected to the first end of the installation part.

[0021] Specifically, when the angle between the first connection direction and the first radial direction is equal to 0°, it can be understood that the first connection direction coincides with the first radial direction. In this case, both the first end and the second end of the installation part are located in the first radial direction. In this case, there is a large space for winding during the process of winding the second electromagnetic heating coil on the installation part. Therefore, the winding difficulty can be reduced.

[0022] In the above technical solution, when the angle between the first connection direction and the first radial direction is greater than 0°, compared with the case where the angle between the first connection direction and the first radial direction is equal to 0°, the distance between the second end of the mounting portion and the axial center position of the mounting barrel is smaller. In this case, the volume of the bracket can be reduced to lower the overall size of the electromagnetic heating assembly.

[0023] In addition, in the above technical solution, without reducing the number of turns of the second electromagnetic heating coil winding, the volume of the bracket can be reduced to ensure the heating power of the electromagnetic heating assembly.

[0024] In addition, since the relative posture between the mounting portion and the mounting barrel has changed, the magnetic field distribution state formed by the second electromagnetic heating coil wound around the mounting portion has also changed, causing the magnetic lines of force emitted from the N pole of the first electromagnetic heating coil to deflect and return to the S pole of the second electromagnetic heating coil. In this case, the heat flow of the cookware located in the magnetic field can be changed, improving the cooking effect during the cooking process.

[0025] In some technical solutions, optionally, the angle between the first connection direction and the first radial direction is less than or equal to 45°.

[0026] In some technical solutions, optionally, at least a part of the mounting portion is bent circumferentially along the mounting barrel from the first end to the second end of the mounting portion.

[0027] In this technical solution, at least a part of the mounting portion is in a bent state, making the distance between the second end of the mounting portion and the axial center position of the mounting barrel further reduced. In this case, the volume of the bracket can be further reduced to lower the overall size of the electromagnetic heating assembly.

[0028] In some technical solutions, the bent part of the mounting portion can be close to the first end of the mounting portion. In this case, the magnetic field strength at the N pole position of the second electromagnetic heating coil can be enhanced, thereby increasing the distance and number of magnetic lines of force rising.

[0029] In some technical solutions, optionally, the mounting barrel and the M mounting portions are of an integral structure.

[0030] In this technical solution, when the mounting barrel and the M mounting portions are of an integral structure, the number of accessories of the electromagnetic heating assembly can be reduced to lower the manufacturing difficulty of the bracket.

[0031] In addition, when the mounting barrel and the M mounting portions are of an integral structure, the relative position relationship between the first electromagnetic heating coil and the second electromagnetic heating coil can be maintained, thereby ensuring the heating effect.

[0032] In some technical solutions, optionally, the bracket further includes a first fixing portion, the first fixing portion is disposed at the second ends of N of the M mounting portions, and the first fixing portion is used to fix the bracket to the seat body; wherein, N is a positive integer less than or equal to M.

[0033] In this technical solution, by providing the first fixing portion, the bracket can be fixed to the seat body by using the first fixing portion, so as to prevent the bracket from shaking on the seat body after the electromagnetic heating assembly is assembled to the seat body, which affects the stability of the electromagnetic heating assembly.

[0034] In the above technical solution, when M is equal to N, the first fixing portion is provided at the second end of each mounting portion. In this case, the bracket and the seat body can be reliably fixed.

[0035] In the above technical solution, when N is less than M, the number of the first fixing portions provided can be selected according to actual use needs, thereby improving the assembly efficiency.

[0036] In the above technical solution, by disposing the first fixing portion at the second end of the mounting portion, the first fixing portion can be more dispersedly distributed, so as to enhance the fixing strength between the bracket and the seat body, and make the bracket and the seat body be reliably fixed.

[0037] In some technical solutions, optionally, the first electromagnetic heating coil is one of a spiral coil and a concentric circle coil; and / or the second electromagnetic heating coil is one of a spiral coil and a concentric circle coil.

[0038] In this technical solution, by defining the first electromagnetic heating coil and the second electromagnetic heating coil as a spiral coil or a concentric circle coil, the magnetic field strength of the electromagnetic heating assembly can be increased by increasing the number of coils, and then the heating power can be increased.

[0039] According to the second aspect of the present invention, the present invention provides an electromagnetic heating device, including: the electromagnetic heating assembly as described in any one of the above.

[0040] In some technical solutions, optionally, it further includes: a panel; a seat body, an accommodation cavity is formed between the seat body and the panel, and the electromagnetic heating assembly is disposed in the accommodation cavity.

[0041] In this technical solution, by providing the panel and the seat body, the panel and the seat body are used to enclose and form an accommodation cavity for accommodating the electromagnetic heating assembly, and then the electromagnetic heating assembly is assembled into the cavity of the accommodation cavity, so as to prevent the electromagnetic heating assembly from being directly exposed for use, thereby eliminating the safety hazards of the electromagnetic heating device and ensuring the use safety of the electromagnetic heating device.

[0042] In some technical solutions, optionally, the panel can be understood as a support for placing cookware, and its forms in different types of electromagnetic heating devices are different.

[0043] Exemplarily, in the case where the electromagnetic heating device is an induction cooker, the panel can be made of ceramic glass.

[0044] Exemplarily, in the case where the electromagnetic heating devices are a rice cooker and an electric pressure cooker, the panel can be a support, where the support can be understood as a structure for accommodating cookware.

[0045] In some technical solutions, optionally, the base body is further provided with: a second fixing part; in the case where the bracket in the electromagnetic heating assembly includes a first fixing part, the second fixing part cooperates with the first fixing part to fix the bracket on the base body.

[0046] In this technical solution, by providing the second fixing part on the base body, so that the second fixing part can cooperate with the first fixing part, and further fix the bracket in the electromagnetic heating assembly on the base body.

[0047] In some technical solutions, optionally, the electromagnetic heating device includes one of the following: an induction cooker, an electric stove, a rice cooker, and an electric pressure cooker.

[0048] The additional aspects and advantages of the present invention will be partly given in the following description, partly will become obvious from the following description, or be understood through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0068] In order to more clearly understand the above aspects, features, and advantages of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0069] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0070] In an embodiment of the present application, as Figure 4 shown, an electromagnetic heating assembly is provided, including: a bracket 402; a first electromagnetic heating coil 404 disposed on the bracket 402; M second electromagnetic heating coils 406 disposed on the bracket 402, spaced apart along the circumferential direction of the first electromagnetic heating coil 404, a first end 4062 of each second electromagnetic heating coil 406 being close to the first electromagnetic heating coil 404, and a second end 4064 of each second electromagnetic heating coil 406 being far from the first electromagnetic heating coil 404, where M is a positive integer; wherein, the first end 4062 and the second end 4064 are two ends in the direction of the wire lamination of the second electromagnetic heating coil 406.

[0071] An embodiment of the present invention provides an electromagnetic heating assembly. In the above electromagnetic heating assembly, as Figure 5 and Figure 6 shown, the N pole formed by the energized second electromagnetic heating coil 406 will be close to the N pole formed by the energized first electromagnetic heating coil 404. When the N poles are close to each other, a repulsive force will be formed between them. Under the action of the above repulsive force, the magnetic field lines around the N pole of the first electromagnetic heating coil 404 and the magnetic field lines around the N pole of the second electromagnetic heating coil 406 will rise. After rising, the magnetic field lines will form a closed curve with the S pole of the second electromagnetic heating coil 406.

[0072] During this process, compared with related embodiments, the rising distance of the magnetic field lines can be increased, thereby increasing the heating distance. At the same time, the magnetic field lines formed by the N pole of the second electromagnetic heating coil 406 also rise synchronously. Therefore, compared with related embodiments, the electromagnetic heating assembly proposed by the present invention can also increase the magnetic field intensity and the coverage range of the magnetic field, so that the sides of more cookware are also within the coverage range of the magnetic field. On this basis, the area where eddy currents appear in the cookware also increases synchronously, realizing three-dimensional heating of the ingredients, thereby improving the heating effect. The probability of the situation where the cookware 500 stops heating due to being far from the first electromagnetic heating coil 404 in the scenario of flipping the pan is improved.

[0073] Since the first end 4062 of the second electromagnetic heating coil 406 is close to the first electromagnetic heating coil 404, the second end 4064 of the second electromagnetic heating coil 406 is far from the first electromagnetic heating coil 404, and the M second electromagnetic heating coils 406 are distributed at intervals along the circumferential direction of the first electromagnetic heating coil 404. Therefore, the second electromagnetic heating coil 406 will form a vertically installed state and a horizontally installed state with the first electromagnetic heating coil 404.

[0074] When the first electromagnetic heating coil 404 is powered on, an N pole can be formed at one end of the first electromagnetic heating coil 404, and an S pole can be formed at the other end. After the second electromagnetic heating coil 406 is powered on, a magnet with an N pole at one end and an S pole at the other end will also be formed, achieving the effect of increasing the upward distance of the magnetic field lines as described above.

[0075] Specifically, the first electromagnetic heating coil 404 and the second electromagnetic coil proposed in the present invention utilize the Halbach principle, thereby increasing the heating distance.

[0076] Among them, as Figure 7 shown, when multiple magnetic bodies are arranged in the manner shown in Figure 7 , the magnetic field lines above the magnetic bodies rise, while the magnetic field lines below the magnetic bodies quickly form closed curves. Based on this, as Figure 8 shown, if the cookware is within the range of the magnetic field lines above the magnetic bodies, the cookware can generate an eddy current effect under the action of the magnetic field.

[0077] Specifically, as Figure 9 shown, after a cookware 500 is set above the first electromagnetic heating coil 404 and the second electromagnetic heating coil 406 shown in Figure 5 , the cookware can generate an eddy current effect under the action of the magnetic field, thereby achieving heating.

[0078] In some embodiments, the direction of the wire lamination of the first electromagnetic heating coil 404 can be understood as that in the axial direction of the winding of the first electromagnetic heating coil 404, the direction of the wire lamination of the second electromagnetic heating coil 406 is defined in the same way as that of the first electromagnetic heating coil 404, which will not be elaborated here.

[0079] In some embodiments, the direction of the wire lamination of the first electromagnetic heating coil 404 can be understood as the direction from the S pole to the N pole of the first electromagnetic heating coil 404. Similarly, the direction of the wire lamination of the second electromagnetic heating coil 406 is defined in the same way as that of the first electromagnetic heating coil 404, which will not be elaborated here.

[0080] In some embodiments, optionally, the support 402 includes: a mounting barrel 4022 for accommodating the first electromagnetic heating coil 404, the axial direction of the mounting barrel 4022 being parallel to the direction of wire lamination of the first electromagnetic heating coil 404; M mounting portions 4024 spaced circumferentially along the mounting barrel 4022, corresponding one-to-one to the M second electromagnetic heating coils 406, and the second electromagnetic heating coils 406 being sleeved on the mounting portions 4024.

[0081] In this embodiment, by providing the mounting barrel 4022, the first electromagnetic heating coil 404 can be directly assembled into the mounting barrel 4022 to reduce the assembly difficulty of the first electromagnetic heating coil 404, and the provided mounting portions 4024 facilitate directly winding the second electromagnetic heating coil 406 on the mounting portions 4024. In this process, since the relative positional relationship between the mounting barrel 4022 and the mounting portions 4024 is fixed, the assembly difficulty of the first electromagnetic heating coil 404 and the second electromagnetic heating coil 406 can be reduced, and the assembly efficiency can be improved.

[0082] In some embodiments, optionally, as Figure 10 shown, the connection line between the first end and the second end of the mounting portion 4024 corresponds to the first connection direction, and the position on the mounting barrel 4022 connected to the first end of the mounting portion 4024 has a first radial direction; wherein, the angle A between the first connection direction and the first radial direction is greater than or equal to 0°.

[0083] In this embodiment, the angle A between the first connection direction and the first radial direction is greater than or equal to 0°, which can be understood as that the angle A between the first connection direction and the first radial direction is equal to 0° or the angle A between the first connection direction and the first radial direction is greater than 0°.

[0084] Among them, the first radial direction can be understood as the connection line direction between the axis of the mounting barrel 4022 and the position on the mounting barrel 4022 connected to the first end of the mounting portion 4024.

[0085] Specifically, when the angle A between the first connection direction and the first radial direction is equal to 0°, it can be understood that the first connection direction coincides with the first radial direction. In this case, both the first end and the second end of the mounting portion 4024 are located in the first radial direction. In this case, there is a relatively large space for winding during the process of winding the second electromagnetic heating coil 406 on the mounting portion 4024. Therefore, the winding difficulty can be reduced.

[0086] In the above embodiments, when the angle A between the first connection direction and the first radial direction is greater than 0°, the distance between the second end of the mounting portion 4024 and the axial center position of the mounting barrel 4022 is smaller than that when the angle A between the first connection direction and the first radial direction is equal to 0°. In this case, the volume of the bracket 402 can be reduced to lower the overall size of the electromagnetic heating assembly.

[0087] In addition, in the above embodiments, without reducing the number of turns of the second electromagnetic heating coil 406, the volume of the bracket 402 can be reduced to ensure the heating power of the electromagnetic heating assembly.

[0088] In addition, since the relative posture between the mounting portion 4024 and the mounting barrel 4022 has changed, the magnetic field distribution state formed by the second electromagnetic heating coil 406 wound around the mounting portion 4024 has also changed, causing the magnetic force lines emitted from the N pole of the first electromagnetic heating coil 404 to deflect and then return to the S pole of the second electromagnetic heating coil 406. In this case, the heat flow of the cookware 500 located in the magnetic field can be changed, improving the cooking effect during the cooking process.

[0089] In some embodiments, optionally, the angle between the first connection direction and the first radial direction is less than or equal to 45°.

[0090] In some embodiments, optionally, at least a part of the mounting portion 4024 is bent along the circumferential direction of the mounting barrel 4022 from the first end to the second end of the mounting portion 4024.

[0091] In this embodiment, at least a part of the mounting portion 4024 is in a bent state, so that the distance between the second end of the mounting portion 4024 and the axial center position of the mounting barrel 4022 is further reduced. In this case, the volume of the bracket 402 can be further reduced to lower the overall size of the electromagnetic heating assembly.

[0092] In some embodiments, the bent part on the mounting portion 4024 can be close to the first end of the mounting portion 4024. In this case, the magnetic field strength at the N pole position of the second electromagnetic heating coil 406 can be enhanced, thereby increasing the distance and number of the magnetic force lines rising upward.

[0093] In some embodiments, optionally, the mounting barrel 4022 and the M mounting portions 4024 are of an integral structure.

[0094] In this embodiment, when the mounting barrel 4022 and the M mounting portions 4024 are of an integral structure, the number of accessories of the electromagnetic heating assembly can be reduced to lower the manufacturing difficulty of the bracket 402.

[0095] In addition, when the installation barrel 4022 and the M installation parts 4024 are of an integral structure, the relative positional relationship between the first electromagnetic heating coil 404 and the second electromagnetic heating coil 406 can be maintained, thereby ensuring the heating effect.

[0096] In some embodiments, optionally, as Figure 10 shown, the bracket 402 further includes a first fixing part 408, the first fixing part 408 is arranged at the second ends of N installation parts 4024 among the M installation parts 4024, and the first fixing part 408 is used to fix the bracket 402 on the seat body 700; wherein, N is a positive integer less than or equal to M.

[0097] In this embodiment, by providing the first fixing part 408, the bracket 402 can be fixed on the seat body 700 by using the first fixing part 408, so as to prevent the electromagnetic heating component from shaking on the seat body after being assembled to the seat body, which affects the stability of the electromagnetic heating component.

[0098] In the above embodiment, when M is equal to N, the first fixing part 408 is arranged at the second end of each installation part 4024. In this case, the bracket 402 and the seat body can be reliably fixed.

[0099] In the above embodiment, when N is less than M, the number of the first fixing parts 408 can be selected according to actual usage needs, thereby improving the assembly efficiency.

[0100] In the above embodiment, by arranging the first fixing part 408 at the second end of the installation part 4024, the first fixing part 408 can be more dispersedly distributed, so as to enhance the fixing strength between the bracket 402 and the seat body, and make the bracket 402 and the seat body be reliably fixed.

[0101] In some embodiments, optionally, the first electromagnetic heating coil 404 is one of a spiral coil and a concentric circle coil; and / or the second electromagnetic heating coil 406 is one of a spiral coil and a concentric circle coil.

[0102] In this embodiment, by defining the first electromagnetic heating coil 404 and the second electromagnetic heating coil 406 as spiral coils or concentric circle coils, the magnetic field intensity of the electromagnetic heating component can be increased by increasing the number of coils, and then the heating power can be increased.

[0103] In one of the embodiments, as Figure 11 、 Figure 12 、 Figure 13 and Figure 14 shown, the present invention provides an electromagnetic heating device, including: an electromagnetic heating component as described in any one of the above.

[0104] In some embodiments, optionally, it further includes: a panel 600; a base 700, an accommodation cavity 800 is formed between the base 700 and the panel 600, and an electromagnetic heating assembly is disposed in the accommodation cavity 800.

[0105] In this embodiment, by providing the panel 600 and the base 700, the accommodation cavity 800 for accommodating the electromagnetic heating assembly is formed by enclosing with the panel 600 and the base 700, and then the electromagnetic heating assembly is assembled into the accommodation cavity 800, so as to avoid the direct exposure of the electromagnetic heating assembly for use, thereby eliminating the safety hazards of the electromagnetic heating device and ensuring the safe use of the electromagnetic heating device.

[0106] In some embodiments, optionally, the panel 600 can be understood as a support for placing the cookware 500, and its manifestation forms are different in different types of electromagnetic heating devices.

[0107] Exemplarily, when the electromagnetic heating device is an induction cooker, the panel 600 can be a ceramic glass.

[0108] Exemplarily, when the electromagnetic heating devices are a rice cooker and an electric pressure cooker, the panel 600 can be a support, where the support can be understood as a structure for accommodating the cookware 500.

[0109] In some embodiments, optionally, the base 700 is further provided with: a second fixing portion 702; when the bracket 402 in the electromagnetic heating assembly includes a first fixing portion 408, the second fixing portion 702 cooperates with the first fixing portion 408 to fix the bracket 402 on the base 700.
