Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and particularly relates 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. Function 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 function 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, there is a large amount of water vapor in the humid environment and crawlers such as cockroaches can easily 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 can easily cause the two high-power terminals to conduct electricity 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 electrical connection between two high-power terminals to form a spark or generate high temperature, resulting in potential safety hazards.

[0006] The present application provides a cooking appliance, which includes:

[0007] A power board, on which two high-power terminals are provided;

[0008] An insulating and heat-insulating member, which includes a first isolation board. The first isolation board is located between the two high-power terminals and insulates and isolates the two high-power terminals.

[0009] For the cooking appliance provided by the present application, the insulating and heat-insulating member can be made of a non-conductive material with an insulating effect. Therefore, the insulating and heat-insulating member can insulate and isolate two adjacent high-power terminals through the first isolation board.

[0010] 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, the possibility of the crawler directly connecting the two high-voltage terminals can be reduced by insulating and isolating the two high-voltage terminals through the first isolation plate.

[0011] In addition, the insulating and heat-insulating member of the embodiment of the present application can have heat insulation properties. The first isolation plate is located between the two strong electric terminals and can be used to block the heat generated by a single strong electric terminal, thereby reducing the possibility of spontaneous combustion caused by the heat concentration of the two strong electric terminals.

[0012] According to an embodiment of the present application, the insulating and heat-insulating member further comprises a second insulating plate. The second insulating plate is located on a side of the power board away from the high-voltage terminal, and at least a portion of the power board is located between the first insulating plate and the second insulating plate.

[0013] In the embodiment of the present application, along the thickness direction of the power board, the first isolation plate and the second isolation plate can clamp at least a portion of the power board so that the insulating and heat-insulating component can be fixed on the power board.

[0014] Furthermore, since at least part of the power board is located between the first isolation plate and the second isolation plate, the second isolation plate can be located between the high-voltage terminal of the power board and the lower cover along the thickness direction of the power board. Since the insulating heat-insulating member has heat-insulating properties, the second isolation plate also has heat-insulating properties. When the insulating heat-insulating member is installed on the power board, and the power board is installed on the lower cover, the second isolation plate can also be used to block the heat generated by the high-voltage terminal from being transferred toward the lower cover, thereby reducing the possibility of spontaneous combustion of the lower cover.

[0015] According to an embodiment of the present application, the insulating and heat-insulating member further comprises a connecting plate, one end of which is connected to the first insulating plate, and the other end of which is connected to the second insulating plate.

[0016] The connecting plate can be used to connect the first isolation plate and the second isolation plate to form an integral structure, thereby improving the structural strength of the insulating and heat-insulating component.

[0017] Furthermore, the insulating thermal insulation member can be limited along the first direction by the connecting plate and the power board. During the process of installing the insulating thermal insulation member on the power board, the insulating thermal insulation member and the power board move relative to each other along the first direction. When the power board abuts against the connecting plate, the first isolation plate can be located between the two high-voltage terminals to insulate and isolate the two high-voltage terminals through the first isolation plate. Therefore, it is easy to understand that the connecting plate can be used to prevent the power board from continuing to move relative to the insulating thermal insulation member, so as to avoid the phenomenon that the first isolation plate is misaligned due to the continued movement of the power board, and the two high-voltage terminals are electrically connected.

[0018] According to an embodiment of the present application, the insulating and heat-insulating member further includes at least one pressing portion, the pressing portion protrudes from the connecting plate, the pressing portion extends toward the power supply board, and the pressing portion abuts against one side surface of the power supply board.

[0019] By abutting the pressing portion against the power supply board, the pressing portion and one side surface of the power supply board can have an interaction force. Therefore, it is necessary to overcome the friction force between the pressing portion and the power supply board to separate the insulating and heat-insulating member from the power supply board, which is beneficial to improving the connection reliability between the insulating and heat-insulating member and the power supply board and avoiding the phenomenon that the insulating and heat-insulating member becomes loose or falls off, resulting in insulation and heat insulation failure.

[0020] According to an embodiment of the present application, one of the pressing portions is disposed at an end of the first isolation board facing the power supply board.

[0021] In the embodiment of the present application, when the insulating and heat-insulating member is fixed to the power supply board, the pressing portion always maintains the acting force of abutting against one side surface of the power supply board. Therefore, the pressing portion needs to have good strength. One of the pressing portions is connected to the first isolation board and is also connected to the connecting plate, which can be used to provide support for the pressing portion and reduce the possibility of the pressing portion cracking due to interaction with the power supply board.

[0022] According to an embodiment of the present application, along the thickness direction of the power supply board, a support portion protrudes from one side of the second isolation board facing the power supply board, and the support portion abuts against the other side surface of the power supply board.

[0023] When the insulating and heat-insulating member is installed on the power supply board, the pressing portion of the insulating and heat-insulating member can abut against the upper surface of the power supply board, and the support portion of the insulating and heat-insulating member can abut against the lower surface of the power supply board, so that the insulating and heat-insulating member can be fixed on the power supply board, and the insulating and heat-insulating member is not easily separated from the power supply board.

[0024] According to an embodiment of the present application, at least one of the pressing portion and the support portion is provided with an inclined guiding surface facing the power supply board.

[0025] Taking the pressing portion provided with an inclined guiding surface as an example, during the process of installing the insulating and heat-insulating member on the power supply board, the inclined guiding surface of the pressing portion can facilitate the installation of the insulating and heat-insulating member on the power supply board. And during the process of inserting the insulating and heat-insulating member onto the power supply board, the friction force between the power supply board and the inclined guiding surface can gradually increase, so that the insulating and heat-insulating member and the power supply board can be in interference fit, and the insulating and heat-insulating member is not easily detached from the power supply board.

[0026] According to an embodiment of the present application, along the first direction, the connecting plate is disposed at an end of the second isolation board, and at least a part of the first isolation board is connected to the connecting plate to form an integral insulating and heat-insulating member.

[0027] The first partition board, the second partition board, and the connecting board are connected and form an integral insulating and heat-insulating member. On the one hand, the overall strength of the insulating and heat-insulating member can be improved, thereby increasing the service life of the insulating and heat-insulating member. On the other hand, the first partition board, the second partition board, and the connecting board do not need to be assembled separately, which is beneficial to improving the assembly efficiency.

[0028] According to an embodiment of the present application, along the thickness direction of the power supply board, the height of the first partition board is greater than the height of any strong electrical terminal.

[0029] By setting the height of the first partition board to be greater than the height of the strong electrical terminal, it is difficult for the crawler to cross the first partition board, thereby reducing the possibility that the crawler connects two strong electrical terminals, resulting in high temperature and sparks, and further causing the cooking appliance to burn.

[0030] According to an embodiment of the present application, it further includes a lower cover. The power supply board is arranged on the lower cover, and the power supply board is close to the side wall of the lower cover. The insulating and heat-insulating member further includes a third partition board. Along the second direction, the third partition board is located between the strong electrical terminal and the side wall.

[0031] The heat generated by the strong electrical terminal is blocked from being transferred in the direction of the side wall by the third partition board.

[0032] 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 these technical features of the 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 manner.

[0051] Through the above - mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions 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 implementation manners

[0052] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying 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 embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0053] 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 operation. 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 field forces. The magnetic field lines 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.

[0054] The cooking appliance includes a power board and a lower cover. The power board is arranged on the lower cover. Among them, function modules such as an IGBT (Insulated Gate Bipolar Transistor) module, a filter circuit, and a rectifier bridge are arranged on the power board. The power board is also provided with a main power terminal for supplying power to the above function modules of the power board.

[0055] In the related art, the distance between the two main 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 pests such as cockroaches are likely to enter the induction cooker. Since water and pests are conductive, if the water vapor or pests are located between the two main power terminals, it is easy to form a conductive bridge, which may easily cause the two main power terminals to conduct, forming a spark or generating high temperature, leading to spontaneous combustion of the power board and the housing of the induction cooker.

[0056] 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 an insulating and heat-insulating member. The insulating and heat-insulating member may include a first partition plate. When the insulating and heat-insulating member is slidably mounted on the power supply board, the first partition plate may be located between two strong electrical terminals. Therefore, the first partition plate can be used for insulating and isolating the two strong electrical terminals, avoiding conduction between the two strong electrical terminals to form a spark or generate high temperature, which is beneficial to reducing the possibility of natural phenomena occurring in the induction cooker.

[0057] 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.

[0058] See Figures 1 to 5 As shown, the cooking appliance 100 in the embodiments of the present application may include a power supply board 120 and an insulating and heat-insulating member 130.

[0059] The power supply board 120 is provided with strong electrical terminals 121. The strong electrical terminals 121 can be used to connect the power cord. The power cord is electrically connected to the strong electrical terminals 121 to supply power to the power supply board 120. During the operation of the cooking appliance 100, a large amount of heat is easily generated at the strong electrical terminals 121.

[0060] The insulating and heat-insulating member 130 may include a first partition plate 131. The first partition plate 131 is located between two strong electrical terminals 121. The first partition plate 131 can insulate and isolate the two strong electrical terminals 121.

[0061] In the embodiments of the present application, the insulating and heat-insulating member 130 may be made of a non-conductive material with an insulating effect. Therefore, the insulating and heat-insulating member 130 can insulate and isolate two adjacent strong electrical terminals 121 through the first partition plate 131.

[0062] Specifically, taking a crawler as an example, when the crawler is located between two strong electrical terminals 121, it is easy to have a phenomenon that one end of the crawler contacts one of the strong electrical terminals 121 and the other end of the crawler contacts the other strong electrical terminal 121, so that it is easy to electrically connect the two strong electrical terminals 121 through the crawler, resulting in high temperature or spark formation. Therefore, insulating and isolating the two strong electrical terminals 121 through the first partition plate 131 can reduce the possibility of the crawler directly connecting the two strong electrical terminals 121.

[0063] In addition, the insulating and heat-insulating member 130 in the embodiments of the present application may have heat insulation. The first partition plate 131 is located between two strong electrical terminals 121 and can be used to block the heat generated by a single strong electrical terminal 121, reducing the concentration of heat of the two strong electrical terminals 121 and the possibility of spontaneous combustion.

[0064] In some examples, the material of the spacer 130 can be, but is not limited to, PP (Polypropylene).

[0065] In some implementable ways, referring to Figure 4 and Figure 5 as shown, the thermal insulation member 130 may further include a second spacer plate 132. The second spacer plate 132 may be located on a side of the power supply board 120 away from the high-voltage terminal 121. At least a part of the power supply board 120 may be located between the first spacer plate 131 and the second spacer plate 132.

[0066] In the embodiments of the present application, along the thickness direction of the power supply board 120, the first spacer plate 131 and the second spacer plate 132 may clamp at least a part of the power supply board 120, so that the thermal insulation member 130 can be fixed on the power supply board 120.

[0067] Moreover, since at least a part of the power supply board 120 is located between the first spacer plate 131 and the second spacer plate 132, therefore, along the thickness direction Z of the power supply board 120, the second spacer plate 132 may be located between the high-voltage terminal 121 of the power supply board 120 and the lower cover 110. Since the thermal insulation member 130 has heat insulation property, the second spacer plate 132 also has heat insulation property. When the thermal insulation member 130 is installed on the power supply board 120 and the power supply board 120 is installed on the lower cover 110, the second spacer plate 132 can also be used to block the heat generated by the high-voltage terminal 121 from being transmitted in the direction of the lower cover 110, reducing the possibility of spontaneous combustion of the lower cover 110.

[0068] In some implementable ways, referring to Figure 4 and Figure 5 as shown, the thermal insulation member 130 may further include a connecting plate 133. One end of the connecting plate 133 may be connected to the first spacer plate 131, and the other end of the connecting plate 133 may be connected to the second spacer plate 132.

[0069] In the embodiments of the present application, the connecting plate 133 can be used to connect the first spacer plate 131 and the second spacer plate 132 to form an integral structure, thereby improving the structural strength of the thermal insulation member 130.

[0070] Moreover, the insulation and heat insulation member 130 can be limited along the first direction X by the connection plate 133 with respect to the power supply board 120. During the installation of the insulation and heat insulation member 130 on the power supply board 120, the insulation and heat insulation member 130 and the power supply board 120 move relative to each other along the first direction X. When the power supply board 120 abuts against the connection plate 133, the first partition plate 131 can be located between the two high-voltage terminals 121 to insulate and isolate the two high-voltage terminals 121 through the first partition plate 131. Therefore, it is easy to understand that the connection plate 133 can be used to block the continuous movement of the power supply board 120 relative to the insulation and heat insulation member 130 to avoid the phenomenon that the first partition plate 131 is displaced due to the continuous movement of the power supply board 120 and the two high-voltage terminals 121 are electrically connected.

[0071] In some examples, the lower cover 110 has a connected bottom wall 111 and side wall 112. The bottom wall 111 and the side wall 112 of the lower cover 110 can enclose a space for accommodating at least a part of the power supply board 120. The power supply board 120 can be disposed on the bottom wall 111, and the power supply board 120 is close to the side wall 112. A limiting rib 1111 can be provided on the bottom wall 111, and the limiting rib 1111 is used to limit the power supply board 120 along the first direction X. The high-voltage terminals 121 can be located at one end of the power supply board 120 close to the limiting rib 1111. Along the first direction X of the power supply board 120, the connection plate 133 can be located between the high-voltage terminals 121 and the limiting rib 1111.

[0072] Since the limiting rib 1111 is provided on the bottom wall 111 and the limiting rib 1111 can also be a part of the lower cover 110, therefore, the connection plate 133 can be used to block the heat of the high-voltage terminals 121 from being transferred in the direction of the limiting rib 1111, thereby reducing the possibility of spontaneous combustion of the lower cover 110 caused by the over-high temperature of the limiting rib 1111.

[0073] In some examples, see Figure 7 and Figure 8 As shown, a limiting protrusion 1112 can also be provided on the bottom wall 111. The limiting rib 1111, the side wall 112 and the limiting protrusion 1112 can form a space matching the second partition plate 132 to limit the second partition plate 132 along the first direction X and the second direction Y, thereby realizing the limitation of the power supply board 120 by limiting the second partition plate 132.

[0074] In some realizable ways, see Figure 4 and Figure 5 As shown, the insulation and heat insulation member 130 of the embodiment of the present application can further include at least one pressing portion 135. The pressing portion 135 can protrude from the connection plate 133. The pressing portion 135 can extend towards the power supply board 120. The pressing portion 135 can be used to abut against one side surface of the power supply board 120.

[0075] In the embodiments of the present application, by pressing against the power supply board 120 with the pressing portion 135, there can be an interaction force between the pressing portion 135 and one side surface of the power supply board 120. Therefore, it is necessary to overcome the frictional force between the pressing portion 135 and the power supply board 120 to separate the insulation and heat insulation member 130 from the power supply board 120, which is beneficial to improving the connection reliability between the insulation and heat insulation member 130 and the power supply board 120, and avoiding the phenomenon of insulation and heat insulation failure caused by loosening or falling off of the insulation and heat insulation member 130.

[0076] In some realizable ways, a slideway 130a for at least part of the power supply board 120 to slide into can be formed between the second isolation board 132 and the pressing portion 135. The insulation and heat insulation member 130 can be fixed on the power supply board 120 by a sliding connection method, so as to provide a simple and convenient installation method for the insulation and heat insulation member 130.

[0077] In some examples, see Figure 2 、 Figure 4 and Figure 5 As shown, the power supply board 120 is fixed on the lower cover 110. Before the power supply board 120 and the insulation and heat insulation member 130 are installed on the lower cover 110, the insulation and heat insulation member 130 can be first fixed on the power supply board 120, and then the insulation and heat insulation member 130 and the power supply board 120 form an integral body and are installed on the lower cover 110.

[0078] In some examples, see Figure 4 As shown, along the first direction X, one end of the slideway 130a has an opening. The power supply board 120 can slide into the slideway 130a through the opening. The connecting plate 133 can be located at the other end of the slideway 130a.

[0079] In some realizable ways, one of the pressing portions 135 can be arranged at the end of the first isolation board 131 facing the power supply board 120.

[0080] In the embodiments of the present application, when the insulation and heat insulation member 130 is fixed on the power supply board 120, the pressing portion 135 always maintains the acting force against one side surface of the power supply board 120. Therefore, the pressing portion 135 needs to have good strength. One of the pressing portions 135 is connected to the first isolation board 131, and this pressing portion 135 is also connected to the connecting plate 133, which can be used to provide support for the pressing portion 135 and reduce the possibility of the pressing portion 135 breaking due to the interaction with the power supply board 120.

[0081] In some realizable ways, see Figure 5 and Figure 6 As shown, along the thickness direction Z of the power supply board 120, a support portion 136 is convexly provided on the side of the second isolation board 132 facing the power supply board 120. The support portion 136 can abut against the other side surface of the power supply board 120 along the thickness direction Z.

[0082] In the embodiments of the present application, when the insulation and heat insulation member 130 is installed on the power supply board 120, the pressing portion 135 of the insulation and heat insulation member 130 can abut against the upper surface of the power supply board 120, and the supporting portion 136 of the insulation and heat insulation member 130 can abut against the lower surface of the power supply board 120, so that the insulation and heat insulation member 130 can be fixed on the power supply board 120, and the insulation and heat insulation member 130 is not easily separated from the power supply board 120.

[0083] Wherein, the supporting portion 136 can protrude from the surface of the second isolation plate 132 facing the power supply board 120, so that there is a gap between the lower surface of the power supply board 120 and the second isolation plate 132. The lower surface of the power supply board 120 and the second isolation plate 132 do not fit together, so as to avoid interference between the contacts on the power supply board 120 and the second isolation plate 132.

[0084] In some implementable ways, referring to Figure 5 As shown, at least one of the pressing portion 135 and the supporting portion 136 can be provided with an inclined guiding surface 130b facing the power supply board 120.

[0085] In the embodiments of the present application, taking the pressing portion 135 provided with the inclined guiding surface 130b as an example, the lower surface of the pressing portion 135 gradually slopes upward from the end close to the connecting plate 133 to the end away from the connecting plate 133 to form the inclined guiding surface 130b. During the process of installing the insulation and heat insulation member 130 on the power supply board 120, the inclined guiding surface 130b of the pressing portion 135 can facilitate the alignment of the sliding track 130a of the insulation and heat insulation member 130 with the power supply board 120. Moreover, during the process of the power supply board 120 sliding in the sliding track 130a of the insulation and heat insulation member 130, the frictional force between the power supply board 120 and the inclined guiding surface 130b can gradually increase, so that an interference fit can be achieved between the insulation and heat insulation member 130 and the power supply board 120, and the insulation and heat insulation member 130 is not easily detached from the power supply board 120.

[0086] In some examples, the structures and sizes of the multiple supporting portions 136 can be but are not limited to one type, and the structures and sizes of the multiple pressing portions 135 can also be but are not limited to one type. The connection stability between the insulation and heat insulation member 130 and the power supply board 120 can be improved through the mutual cooperation of the multiple pressing portions 135 and the supporting portions 136. For example, along the first direction X, both ends of one of the supporting portions 136 can be flush with both ends of the second isolation plate 132 to have a larger contact area with the power supply board 120.

[0087] In the embodiments of the present application, the first partition plate 131, the second partition plate 132, and the connecting plate 133 are connected to form an integral insulating and heat-insulating member 130. On the one hand, the overall strength of the insulating and heat-insulating member 130 can be improved, thereby improving the service life of the insulating and heat-insulating member 130. On the other hand, the first partition plate 131, the second partition plate 132, and the connecting plate 133 do not need to be assembled separately, which is conducive to improving the assembly efficiency.

[0088] Wherein, when the insulating and heat-insulating member 130 is installed on the power supply board 120, the first partition plate 131 can achieve insulation isolation and heat insulation between the two insulating terminals 121. The second partition plate 132 can be used to block the heat of the two insulating terminals 121 from being transferred in the direction of the bottom wall 111 of the lower cover 110. The connecting plate 133 can be used to block the heat of the two insulating terminals 121 from being transferred in the direction of the limiting rib 1111 of the lower cover 110.

[0089] In some examples, the pressing portion 135 can be disposed on the surface of the connecting plate 133 facing the power supply board 120, and at least a part of the supporting portion 136 can be connected to the connecting plate 133.

[0090] In some implementable ways, see Figure 3 and Figure 6 As shown, along the thickness direction Z of the power supply board 120, the height of the first partition plate 131 can be greater than the height of any high-voltage terminal 121.

[0091] When the cooking appliance 100 is in a humid environment, it is easy for crawlers such as cockroaches to enter the cooking appliance 100. Since the crawlers are conductors, when a crawler climbs to the top of one of the high-voltage terminals 121, it is easy for the crawler to span to the other high-voltage terminal 121. At this time, both ends of the crawler are located on the two high-voltage terminals 121 respectively, and it is easy for the crawler to conduct the two high-voltage terminals 121. Therefore, by setting the height of the first partition plate 131 to be greater than the height of the high-voltage terminal 121, the crawler is not easy to cross the first partition plate 131, thereby reducing the possibility that the crawler connects the two high-voltage terminals 121, resulting in high temperature and sparks, and further causing the cooking appliance 100 to burn.

[0092] In some implementable ways, see Figure 7 and Figure 8 As shown, along the second direction Y, the power supply board 120 can be close to the side wall 112 of the lower cover 110. The insulating and heat-insulating member 130 can further include a third partition plate 134. The third partition plate 134 can be located between the high-voltage terminal 121 and the side wall 112.

[0093] In the embodiments of the present application, the insulating and heat-insulating member 130 can block the heat generated by the high-voltage terminal 121 from being transferred in the direction of the side wall 112 through the third partition plate 134.

[0094] In some examples, when the power supply board 120 is installed on the lower cover 110, the high-voltage terminal 121 can be close to one of the side walls 112. For example, along the first direction X, the high-voltage terminal 121 is close to the limiting rib 1111, and along the second direction Y, the high-voltage terminal 121 is close to one of the side walls 112. At this time, since the insulation and heat insulation member 130 is installed on the power supply board 120, when the power supply board 120 is installed on the lower cover 110, the third partition plate 134 can be located between the high-voltage terminal 121 and the side wall 112, so that the third partition plate 134 can block at least part of the heat generated by the high-voltage terminal 121 from being transferred to the side wall 112.

[0095] In some examples, when the connecting plate 133 is close to the middle area of the cooking appliance 100, along the thickness direction Z of the power supply board 120, the height of the connecting plate 133 can be less than the height of the third partition plate 134, so as to avoid the connecting plate 133 occupying a large height space inside the cooking appliance 100 and affecting the layout of other components inside the cooking appliance 100.

[0096] Therefore, in the embodiments of the present application, the insulation and heat insulation member 130 can block the heat from being transferred to the lower cover 110 from multiple angles of the high-voltage terminal 121, including blocking the heat from being transferred circumferentially outward from the high-voltage terminal 121 to the side wall 112, and can also include blocking the heat from being transferred downward from the bottom of the high-voltage terminal 121 to the bottom wall 111, thereby being beneficial to reducing the possibility that the lower cover 110 reaches its own ignition point due to excessive heat and causing spontaneous combustion of the lower cover 110.

[0097] In some feasible ways, refer to Figure 5 and Figure 8 As shown, a convex structure 130c can be provided on the side of the third partition plate 134 facing away from the power supply board 120 for abutting against the side wall 112. The convex structure 130c can be used to prevent the third partition plate 134 from directly contacting the side wall 112, so that the heat of the third partition plate 134 is not easily directly transferred to the side wall 112, which is beneficial to reducing the heat transfer of the third partition plate 134 to the side wall 112, thereby reducing the possibility of spontaneous combustion of the lower cover 110.

[0098] Similarly, a convex structure 130c can be provided on the side of the connecting plate 133 facing away from the power supply board 120 for abutting against the limiting rib 1111. The convex structure 130c can be used to prevent the connecting plate 133 from directly contacting the limiting rib 1111, so that the heat of the connecting plate 133 is not easily directly transferred to the limiting rib 1111, which is beneficial to reducing the heat transfer of the connecting plate 133 to the limiting rib 1111, thereby reducing the possibility of spontaneous combustion of the lower cover 110.

[0099] In some feasible ways, refer to Figure 1As shown, the cooking appliance 100 may further include a coil plate 140, a panel 150, and an upper cover 160. The upper cover 160 and the lower cover 110 may be connected to each other. The panel 150 may be disposed on the upper cover 160 for supporting a cooking pot. The coil plate 140 is located in the space between the panel 150 and the lower cover 110.
