Description
Technical Field
[0001] The present application relates to the technical field of household appliances, and particularly to a cooking appliance. Background Art
[0002] Cooking appliances such as induction cookers have the advantages of fast heating, no open flame, safety and convenience, and are increasingly favored and recognized by consumers. When an induction cooker is working, it can use high-frequency alternating current to pass through a coil disk to generate a high-frequency changing magnetic field. The high-frequency changing magnetic field can generate eddy currents at the bottom of a metal cookware placed on the induction cooker to heat the food in the metal cookware.
[0003] The cooking appliance includes a power board. The power board is located inside the housing of the cooking appliance. Functional modules such as an IGBT (Insulated Gate Bipolar Transistor) module, a filter circuit, and a rectifier bridge are provided on the power board. A set of high-power terminals for supplying power to the above functional modules of the power board is also provided on the power board.
[0004] In related technologies, the distance between two high-power terminals is small and they are exposed to the internal environment of the housing. When the cooking appliance is in a humid environment, the water vapor in the humid environment is large and crawlers such as cockroaches are likely to enter the induction cooker. Since water and crawlers are conductive, if the water vapor or crawlers are located between the two high-power terminals, it is easy to form a conductive bridge, which is likely to cause the two high-power terminals to conduct to form a spark or generate high temperature, leading to spontaneous combustion of the power board and the lower housing of the induction cooker. Summary of the Utility Model
[0005] The present application provides a cooking appliance, which can solve the problem that when the cooking appliance is applied to a humid environment, it is easy to cause an electrical connection between two high-power terminals to form a spark or generate high temperature, resulting in a safety hazard.
[0006] The present application provides a cooking appliance, which includes:
[0007] A power board, on which two adjacent high-power terminals are provided;
[0008] An isolation member, at least one of the high-power terminals is provided with the isolation member, the isolation member includes a first insulating board, the isolation member can cover the outer periphery of the high-power terminal, so that the first insulating board is located between the two high-power terminals, and the first insulating board insulates and isolates the two high-power terminals.
[0009] In the cooking utensil provided by the present application, the isolating member can insulate and isolate two adjacent high-voltage terminals through a first insulating plate. Taking a crawler as an example, when the crawler is located between two high-voltage terminals, it is easy for one end of the crawler to contact one of the high-voltage terminals, and the other end of the crawler to contact the other high-voltage terminal, so that the two high-voltage terminals are easily electrically connected through the crawler, resulting in high temperature or sparks. Therefore, in an embodiment of the present application, the two high-voltage terminals can be insulated and isolated by the first insulating plate of the isolating member to reduce the possibility of the crawler directly connecting to the two high-voltage terminals.
[0010] In addition, the isolating member of the embodiment of the present application may have heat insulation properties. By arranging the isolating member to cover the outer periphery of the high-voltage terminal, it can be used to block the heat generated by the high-voltage terminal from diffusing outward along the circumferential direction, thereby reducing the possibility of the heat of the high-voltage terminal being transferred to the side wall of the lower shell, resulting in excessive temperature at the side wall of the lower shell and spontaneous combustion.
[0011] According to an embodiment of the present application, the isolating member is provided with a mounting hole which penetrates along the thickness direction of the power board, the high-voltage terminal can be inserted into the mounting hole, and the isolating member is engaged with the high-voltage terminal.
[0012] In the embodiment of the present application, the through direction of the mounting hole can be the same direction as the thickness direction of the power board. Therefore, the isolating member can be installed on the high-voltage terminal along the thickness direction of the power board. The assembler can match the isolating member with the high-voltage terminal, and then apply a downward pressing force to the isolating member to sleeve the isolating member on the outside of the high-voltage terminal. It is easy to understand that the pressing assembly method is simple to operate and easy to apply force, which is conducive to the rapid installation of the isolating member.
[0013] Furthermore, the isolating piece can be snap-fitted and fixed to the high-voltage terminal, so that during the displacement and transportation of the cooking appliance, the isolating piece is not easily separated from the high-voltage terminal, which may cause the isolating piece to fail.
[0014] According to one embodiment of the present application, the isolation member includes an insulating wall, which is arranged on the first insulating plate, and the insulating wall extends along the thickness direction of the power board to exceed the height of the high-voltage terminal.
[0015] When the crawler moves upward along the side wall of the first insulating plate to the top of the first insulating plate, it is easy for the crawler to cross the first insulating plate. At this time, the two ends of the crawler are respectively located on the two high-voltage terminals, and there is a possibility that the crawler conducts the two high-voltage terminals. Therefore, by setting the insulating wall to exceed the height of the high-voltage terminals, it can be difficult for the crawler to cross the insulating wall, thereby reducing the possibility of the above-mentioned problem.
[0016] According to one embodiment of the present application, the isolation member further includes a second insulating plate, and the second insulating plate is arranged opposite to the first insulating plate along the first direction;
[0017] The second insulating plate is provided with the insulating wall, and the insulating wall extends along the thickness direction of the power board, and the insulating wall exceeds the height of the high-voltage terminal.
[0018] The second insulating plate is close to the side wall of the lower shell. Therefore, the insulating wall and the second insulating plate can have a heat-insulating effect, so as to prevent the heat generated by the high-voltage terminal from diffusing circumferentially to the side wall of the lower shell, thereby reducing the possibility of spontaneous combustion caused by the high temperature of the side wall of the lower shell.
[0019] According to one embodiment of the present application, the isolation member further includes a third insulating plate and a fourth insulating plate, and the third insulating plate is arranged opposite to the fourth insulating plate along the second direction;
[0020] The first insulating plate, the second insulating plate, the third insulating plate and the fourth insulating plate are connected and covered on the outer periphery of the high-voltage terminal.
[0021] In the embodiment of the present application, when the isolation piece is provided on one of the high-voltage terminals, the first insulating plate, the third insulating plate, the second insulating plate and the fourth insulating plate can be covered on the periphery of the high-voltage terminal. Therefore, the high-voltage terminal can be insulated to prevent crawlers from easily crawling onto the high-voltage terminal, thereby reducing the possibility of crawlers conducting the two high-voltage terminals.
[0022] According to an embodiment of the present application, the isolation member is provided with an opening penetrating along the thickness direction of the power board, and the opening is arranged on one of the second insulating plate, the third insulating plate and the fourth insulating plate.
[0023] In the embodiment of the present application, when the isolating piece is pressed against the high-voltage terminal and the high-voltage terminal is passed through the small opening end of the mounting hole, the isolating piece is easily deformed. The deformation of the isolating piece can be released through the opening to avoid the possibility that the isolating piece may break, which may lead to the inability to fix the isolating piece to the high-voltage terminal.
[0024] Furthermore, the opening of the isolating member can be used to provide a force point for the disassembly of the isolating member, so as to facilitate the disassembly of the isolating member. Specifically, when disassembling the isolating member, the assembler can insert a finger into the opening, and then pry the isolating member apart along the circumference of the strong current terminal, thereby realizing the disassembly of the isolating member.
[0025] According to an embodiment of the present application, the inner walls opposite to each other of the first insulating plate and the second insulating plate are provided with a clamping portion, and the high-voltage terminal is provided with a clamping space corresponding to the clamping portion, and at least part of the clamping portion is located in the clamping space.
[0026] In the embodiment of the present application, the engaging portion is located in the engaging space of the high-voltage terminal, so that the engaging portion is not easily separated from the high-voltage terminal, thereby fixing the isolating member.
[0027] According to an embodiment of the present application, the inner walls of the first insulating plate and the second insulating plate are provided with first limiting portions, and the high-voltage terminal is located between the two first limiting portions to limit the isolating member in the first direction.
[0028] And / or, the inner walls of the third insulating plate and the fourth insulating plate are provided with second limiting portions, and the high-voltage terminal is located between the two second limiting portions to limit the isolating member in the second direction.
[0029] In the embodiment of the present application, the first limiting portion can be used to restrict the displacement of the isolating member relative to the high-voltage terminal in the first direction, so as to avoid the displacement of the cooking appliance and the offset of the isolating member relative to the high-voltage terminal during transportation, and the collision between the isolating member and the high-voltage terminal to generate abnormal noise.
[0030] The second limiting portion can be used to restrict the displacement of the isolating member relative to the high-voltage terminal in the second direction, so as to avoid the offset of the isolating member relative to the high-voltage terminal during displacement and transportation, and the collision between the isolating member and the high-voltage terminal to generate abnormal noise.
[0031] According to an embodiment of the present application, the cooking appliance includes a first heat insulation member, the first heat insulation member is located on the side of the power supply board facing away from the high-voltage terminal, and the first heat insulation member corresponds to the high-voltage terminal.
[0032] In the embodiment of the present application, the isolating member can have a heat insulation effect. The isolating member sleeved on the outside of the high-voltage terminal can be used to reduce the possibility that the heat generated by the high-voltage terminal diffuses circumferentially outward to the side wall of the lower housing, resulting in the side wall of the lower housing having too high a temperature and catching fire spontaneously.
[0033] According to an embodiment of the present application, a heating module is provided on the power supply board, the cooking appliance includes a second heat insulation member, and at least a part of the second heat insulation member is located on the side of the power supply board facing away from the high-voltage terminal, and the power supply board corresponds to the heating module.
[0034] In the embodiment of the present application, the heating module may refer to a functional module such as an IGBT module. Therefore, a second heat insulation member can be provided in the area corresponding to the IGBT module below the power supply board to block the possibility that the heat generated by the heating module diffuses downward to the bottom wall of the lower housing.
[0035] In addition to the technical problems solved by the embodiments of the present utility model described above, the technical features constituting the technical solutions, and the beneficial effects brought by the technical features of these technical solutions, other technical problems that can be solved by the cooking appliance provided by the embodiments of the present utility model, other technical features included in the technical solutions, and the beneficial effects brought by these technical features will be further described in detail in the specific implementation manners.

These drawings and the written description are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of the Specific Embodiment
[0056] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present application. On the contrary, they are only examples of the devices and methods consistent with some aspects of the present application as detailed in the appended claims. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts fall within the scope of protection of the present application.
[0057] Cooking appliances such as induction cookers are commonly used heating devices and can be used with cookware. Taking the heating device as an induction cooker as an example, the heating device may include a panel, a housing, and a coil disk. The panel and the housing can enclose a relatively airtight cavity for shielding the live components such as the internal power board, control board, and coil disk during the working process. Among them, the control board is electrically connected to the coil disk to control the opening and closing of the coil disk through the control board. When working, high - frequency current passing through the coil disk can generate countless closed magnetic force fields. The magnetic lines of force cutting the cookware can generate countless small eddy currents, causing the cookware placed on the panel to heat up. When in use, the cookware is placed on the panel of the heating device. The cooking appliance can be used to cook the ingredients in the pot.
[0058] The cooking appliance includes a power supply board. The power supply board is located inside the housing of the cooking appliance. Functional modules such as an IGBT (Insulated Gate Bipolar Transistor) module, a filter circuit, and a rectifier bridge are provided on the power supply board. A set of high-voltage terminals for supplying power to the above-mentioned functional modules of the power supply board are also provided on the power supply board.
[0059] In the related art, the distance between two high-voltage terminals is small and they are exposed to the internal environment of the housing. When the cooking appliance is in a humid environment, there is a large amount of water vapor in the humid environment and it is easy for crawlers such as cockroaches to enter the induction cooker. Since water and crawlers are conductive, if water vapor or crawlers are located between the two high-voltage terminals, it is easy to form a conductive bridge, which can easily cause the two high-voltage terminals to conduct, forming a spark or generating high temperature, leading to spontaneous combustion of the power supply board and the lower housing of the induction cooker.
[0060] Based on the above technical problems, the applicant has improved the structure of the existing cooking appliance. In the embodiments of the present application, the cooking appliance may be provided with a separator. The separator can be used to insulate and isolate the two high-voltage terminals. The first insulating plate of the separator can separate the two high-voltage terminals, so that in a humid environment, the first insulating plate can be used to block water vapor or crawlers to prevent water vapor or crawlers from connecting the two high-voltage terminals as a conductor, thus reducing the possibility of forming a spark or generating high temperature and causing the cooking appliance to catch fire.
[0061] The cooking appliance 100 provided by the present application will be described below with reference to the accompanying drawings and in combination with specific embodiments.
[0062] See Figures 1 to 7 As shown, the cooking appliance 100 of the embodiments of the present application may include a power supply board 120 and at least one separator 130.
[0063] Two adjacent high-voltage terminals 121 may be provided on the power supply board 120. Among them, the high-voltage terminal 121 can be used to connect the power cord. The power cord is electrically connected to the high-voltage terminal 121 to supply power to the power supply board 120.
[0064] At least one high-voltage terminal 121 is provided with a separator 130. The separator 130 may include a first insulating plate 134. The separator 130 can be wrapped around the outer periphery of the high-voltage terminal 121, so that the first insulating plate 134 is located between the two high-voltage terminals 121. The first insulating plate 134 can insulate and isolate the two high-voltage terminals 121.
[0065] In the embodiments of the present application, the separator 130 is made of a non-conductive material with an insulating effect. The separator 130 can insulate and isolate two adjacent high-voltage terminals 121 through the first insulating plate 134.
[0066] Specifically, taking the crawler as an example, when the crawler is located between two high-voltage terminals 121, it is easy for one end of the crawler to contact one of the high-voltage terminals 121, and the other end of the crawler to contact the other high-voltage terminal 121, thus easily electrically connecting the two high-voltage terminals 121 through the crawler, resulting in high temperature or spark formation. Therefore, in the embodiments of the present application, the two high-voltage terminals 121 can be insulated and separated by the first insulating plate 134 of the spacer 130 to reduce the possibility of the crawler directly connecting the two high-voltage terminals 121.
[0067] In addition, the spacer 130 of the embodiments of the present application can have heat insulation properties. By arranging the spacer 130 to cover the outer periphery of the high-voltage terminal 121, it can be used to block the heat generated by the high-voltage terminal 121 from diffusing outward in the circumferential direction, thereby reducing the possibility that the heat of the high-voltage terminal 121 is transferred to the side wall 111 of the lower housing 110, resulting in spontaneous combustion due to excessive temperature at the side wall 111 of the lower housing 110.
[0068] In some examples, the material of the spacer 130 can be, but is not limited to, PP (Polypropylene).
[0069] For the convenience of description, when the cooking appliance 100 is placed on a horizontal workbench, the first direction X and the second direction Y of the embodiments of the present application can refer to two directions in the horizontal direction, and the thickness direction Z of the power supply board 120 can be the vertical direction.
[0070] In some examples, two adjacent high-voltage terminals 121 can be arranged at intervals along the first direction X. Along the first direction X, the orthographic projections of two adjacent high-voltage terminals 121 can both be located inside the orthographic projection of the first insulating plate 134. In other words, along the second direction Y, the size of the first insulating plate 134 is larger than the size of the high-voltage terminal 121, and along the thickness direction Z of the power supply board 120, the size of the first insulating plate 134 is larger than the size of the high-voltage terminal 121, so that the two high-voltage terminals 121 can be insulated and separated by the first insulating plate 134.
[0071] In some implementable ways, as shown in Figure 2 the spacer 130 can be provided with a mounting hole 130a penetrating along the thickness direction Z of the power supply board 120. The high-voltage terminal 121 can pass through the mounting hole 130a. The spacer 130 is snap-fitted to the high-voltage terminal 121.
[0072] In the embodiment of the present application, the through direction of the mounting hole 130a may be the same as the thickness direction Z of the power supply board 120. Therefore, the spacer 130 can be mounted on the high-voltage terminal 121 along the thickness direction Z of the power supply board 120. The assembler can align the spacer 130 with the high-voltage terminal 121, and then apply a downward pressing force to the spacer 130 to sleave the spacer 130 outside the high-voltage terminal 121. It is easy to understand that the pressing assembly method is simple to operate and convenient for applying force, which is beneficial to the rapid installation of the spacer 130.
[0073] Moreover, the spacer 130 can be snap-fitted and fixed to the high-voltage terminal 121, so that during the displacement, transportation, etc. of the cooking appliance 100, the spacer 130 is not easily detached from the high-voltage terminal 121, resulting in the failure of the spacer 130.
[0074] It is easy to understand that after the spacer 130 falls off, it is easy to collide with the structures on the power supply board 120. On the one hand, it is easy to damage other structures on the power supply board 120, affecting the service performance and service life of the power supply board 120. On the other hand, it is easy to generate abnormal noises, affecting the user experience.
[0075] In some implementable ways, referring to Figure 2 and Figure 3 as shown, the spacer 130 may include an insulating wall 138. The insulating wall 138 may be disposed on the first insulating plate 134. The insulating plate may extend along the thickness direction Z of the power supply board 120 to exceed the height of the high-voltage terminal 121.
[0076] When the crawler moves upward along the side wall of the first insulating plate 134 to the top of the first insulating plate 134, it is easy for the crawler to straddle the first insulating plate 134. At this time, the two ends of the crawler are respectively located on the two high-voltage terminals 121, and there is a possibility that the crawler conducts the two high-voltage terminals 121. Therefore, by setting the height of the insulating wall 138 to exceed the height of the high-voltage terminal 121, it is not easy for the crawler to cross the insulating wall 138, thereby reducing the possibility of the above problems.
[0077] In some examples, among the two high-voltage terminals 121, the spacer 130 may be disposed on one of the high-voltage terminals 121, or each high-voltage terminal 121 may be provided with a spacer 130, which is not limited in this embodiment.
[0078] In some implementable ways, referring to Figure 2 and Figure 3As shown, the spacer 130 of the embodiment of the present application may further include a second insulating plate 136. The second insulating plate 136 is disposed opposite to the first insulating plate 134 along the first direction X. Wherein, the second insulating plate 136 may be provided with an insulating wall 138. The insulating wall 138 may extend along the thickness direction Z of the power supply board 120. The insulating wall 138 may exceed the height of the high-voltage terminal 121.
[0079] In the embodiment of the present application, the second insulating plate 136 is disposed opposite to the first insulating plate 134 along the first direction X, and the first insulating plate 134 is located between the two high-voltage terminals 121. At this time, the second insulating plate 136 is close to the side wall 111 of the lower housing 110. Therefore, the insulating wall 138 and the second insulating plate 136 can play a heat insulation role to block the circumferential diffusion of the heat generated by the high-voltage terminal 121 to the side wall 111 of the lower housing 110, and reduce the possibility of spontaneous combustion caused by the high temperature of the side wall 111 of the lower housing 110.
[0080] In some examples, when the spacer 130 is installed incorrectly so that the second insulating plate 136 is located between the two high-voltage terminals 121, since the second insulating plate 136 is also provided with an insulating wall 138, therefore, the second insulating plate 136 and the insulating wall 138 can play a role in insulating and isolating the two high-voltage terminals 121. Specifically, the insulating wall 138 on the second insulating plate 136 can reduce the possibility that a crawling insect crosses the second insulating plate 136 and causes the crawling insect to connect the two high-voltage terminals 121.
[0081] In some implementable ways, refer to Figures 4 to 7 As shown, the spacer 130 of the embodiment of the present application may further include a third insulating plate 135 and a fourth insulating plate 137. The third insulating plate 135 and the fourth insulating plate 137 may be disposed opposite to each other along the second direction Y. Wherein, the first insulating plate 134, the second insulating plate 136, the third insulating plate 135 and the fourth insulating plate 137 are connected and cover the outer periphery of the high-voltage terminal 121.
[0082] In the embodiment of the present application, when the spacer 130 is disposed on one of the high-voltage terminals 121, the first insulating plate 134, the second insulating plate 136, the third insulating plate 135 and the fourth insulating plate 137 can cover the outer periphery of the high-voltage terminal 121. Therefore, insulation treatment can be performed on the high-voltage terminal 121, so that it is not easy for crawling insects to climb onto the high-voltage terminal 121, thereby reducing the possibility that the crawling insects conduct the two high-voltage terminals 121.
[0083] In some examples, refer to Figure 2 and Figure 5 As shown, the first insulating plate 134, the third insulating plate 135, the second insulating plate 136 and the fourth insulating plate 137 may enclose to form an installation hole 130a through which the high-voltage terminal 121 can pass.
[0084] In some possible implementations, see Figure 2 and Figure 5 As shown, the isolation member 130 of the embodiment of the present application is provided with an opening 130 b along the thickness direction Z of the power board 120 , and one of the second insulating plate 136 , the third insulating plate 135 and the fourth insulating plate 137 is provided with an opening 130 b .
[0085] During the process of the isolating member 130 being pressed against the high-voltage terminal 121, when the high-voltage terminal 121 is inserted into the small opening 130b of the mounting hole 130a, the isolating member 130 is easily deformed. The deformation of the isolating member 130 can be released through the opening 130b to avoid the possibility that the isolating member 130 breaks and the isolating member 130 cannot be fixed to the high-voltage terminal 121.
[0086] Furthermore, the opening 130b of the isolating member 130 can be used to provide a force application point for the disassembly of the isolating member 130, so as to facilitate the disassembly of the isolating member 130. Specifically, when disassembling the isolating member 130, the assembler can insert a finger into the opening 130b, and then break the isolating member 130 apart along the circumference of the strong electric terminal 121, thereby realizing the disassembly of the isolating member 130.
[0087] It should be noted that, since the first insulating plate 134 is located between the two high-voltage terminals 121 , the opening 130 b is not easily disposed on the first insulating plate 134 to avoid the possibility of water vapor or insects connecting the two high-voltage terminals 121 .
[0088] In some possible implementations, see Figures 2 to 7 As shown, the inner walls of the first insulating plate 134 and the second insulating plate 136 of the present embodiment are both provided with a clamping portion 131. The strong current terminal 121 is provided with a clamping space 121a corresponding to the clamping portion 131, and at least part of the clamping portion 131 is located in the clamping space 121a.
[0089] In the embodiment of the present application, the engaging portion 131 is located in the engaging space 121 a of the high-voltage terminal 121 , so that the engaging portion 131 is not easily separated from the high-voltage terminal 121 , thereby fixing the isolation member 130 .
[0090] In some examples, the engaging portion 131 may be provided with an inclined guide surface 131a. When the isolating member 130 is installed downwardly on the strong electric terminal 121, the inclined guide surface 131a of the isolating member 130 cooperates with the strong electric terminal 121 to guide the engaging portion 131 into the engaging space 121a of the strong electric terminal 121.
[0091] In some examples, the high-voltage terminal 121 may include a horizontally arranged limiting plate 1211. When the engaging portion 131 is located in the engaging space 121a of the high-voltage terminal 121, the limiting plate 1211 can block the movement of the engaging portion 131 away from the power supply board 120, so as to realize the limiting of the spacer 130 and the high-voltage terminal 121 along the thickness direction Z of the power supply board 120.
[0092] In some implementable ways, referring to Figure 2 , Figure 5 and Figure 7 As shown, the inner walls of the first insulating plate 134 and the second insulating plate 136 of the embodiment of the present application may be provided with first limiting portions 132. The high-voltage terminal 121 may be located between the two first limiting portions 132 to limit the spacer 130 in the first direction X.
[0093] In the embodiment of the present application, the first limiting portion 132 can be used to restrict the spacer 130 from generating displacement relative to the high-voltage terminal 121 in the first direction X, so as to avoid the spacer 130 shifting relative to the high-voltage terminal 121 during the shifting and transportation of the cooking appliance 100, and to prevent the spacer 130 and the high-voltage terminal 121 from colliding with each other to generate abnormal noises.
[0094] In some implementable ways, referring to Figure 2 , Figure 5 and Figure 7 As shown, the inner walls of the third insulating plate 135 and the fourth insulating plate 137 are provided with second limiting portions 133, and the high-voltage terminal 121 is located between the two second limiting portions 133 to limit the spacer 130 in the second direction Y.
[0095] In the embodiment of the present application, the second limiting portion 133 can be used to restrict the spacer 130 from generating displacement relative to the high-voltage terminal 121 in the second direction Y, so as to avoid the spacer 130 shifting relative to the high-voltage terminal 121 during the shifting and transportation, and to prevent the spacer 130 and the high-voltage terminal 121 from colliding with each other to generate abnormal noises.
[0096] In some implementable ways, referring to Figure 1 As shown, the cooking appliance 100 may include a first heat insulation member 140. The first heat insulation member 140 may be located on the side of the power supply board 120 facing away from the high-voltage terminal 121. Among them, the first heat insulation member 140 corresponds to the high-voltage terminal 121.
[0097] In the embodiment of the present application, the spacer 130 can have a heat insulation effect. The spacer 130 sleeved outside the high-voltage terminal 121 can be used to reduce the possibility that the heat generated by the high-voltage terminal 121 diffuses circumferentially outward to the side wall 111 of the lower housing 110, resulting in the side wall 111 of the lower housing 110 having too high a temperature and catching fire spontaneously.
[0098] In the embodiment of the present application, during the operation of the cooking appliance 100, the high-voltage terminal 121 is likely to generate a large amount of heat. Therefore, by providing the first heat insulation member 140, it can be used to block the heat generated at the high-voltage terminal 121 from diffusing downward to the bottom wall 112 of the lower housing 110, reducing the possibility of spontaneous combustion due to the high temperature of the bottom wall 112 of the lower housing 110.
[0099] In some implementable ways, as shown in Figure 1 a heat generating module is provided on the power supply board 120. The cooking appliance 100 may include a second heat insulation member 150. At least a part of the second heat insulation member 150 may be located on the side of the power supply board 120 facing away from the high-voltage terminal 121, corresponding to the heat generating module on the power supply board 120.
[0100] In the embodiment of the present application, the heat generating module may refer to a functional module such as an IGBT module. Therefore, a second heat insulation member 150 may be provided in the area corresponding to the IGBT module below the power supply board 120 to block the heat generated by the heat generating module from diffusing downward to the bottom wall 112 of the lower housing 110.
[0101] In some examples, the first heat insulation member 140 and at least a part of the second heat insulation member 150 are located between the power supply board 120 and the lower housing 110. Therefore, by locking the power supply board 120 to the lower housing 110, the first heat insulation member 140 and at least a part of the second heat insulation member 150 can be pressed between the power supply board 120 and the lower housing 110, thus eliminating the need to set up other structures to fix the first heat insulation member 140 and the second heat insulation member 150, which is beneficial to reducing the assembly difficulty and improving the assembly efficiency.
[0102] In some examples, the second heat insulation member 150 may include a first plate body 151 and a second plate body 152. The first plate body 151 may be located between the power supply board 120 and the lower housing 110. The second plate body 152 may be a vertical plate. When the second heat insulation member 150 is fixed between the power supply board 120 and the lower housing 110, the second plate body 152 may be located between the heat generating module and the side wall 111 of the lower housing 110 to block the heat of the heat generating module from diffusing to the side wall 111 of the lower housing 110.
[0103] In some examples, the first heat insulation member 140 and the second heat insulation member 150 may be, but are not limited to, mica sheets.
[0104] In some implementable ways, the cooking appliance 100 may further include a coil disk 160, a panel 170, and an upper housing 180. The upper housing 180 and the lower housing 110 may be connected to each other. The panel 170 may be disposed on the upper housing 180 to support the cookware. The coil disk 160 is located in the space between the panel 170 and the lower housing 110.
