Description
Technical Field
[0001] The utility model relates to the field of small household appliances, in particular to a cooking appliance. Background Art
[0002] A cooking appliance is an appliance that heats a cooking pot through a heating element. Since the heating element has a relatively high temperature during operation, usually up to 300 °C at the highest. For control components such as a power connector or an electronic control board, their heat resistance is relatively low.
[0003] The heat of the heating element is relatively easy to enter the installation position of the power connector or the electronic control board, which easily causes the temperature of the control component to exceed the standard, thereby bringing safety problems. Usually, a reflective cover and mica sheets are used for heat insulation. However, due to the presence of many avoidance holes or wire passing holes on both the reflective cover and the mica sheets, there is still a problem of poor heat insulation effect, resulting in safety issues. Summary of the Utility Model
[0004] In view of this, it is necessary to provide a cooking appliance to improve the heat insulation effect in view of the above problems.
[0005] The utility model provides a cooking appliance, including a base assembly and a cooking pot. The cooking pot is placed on the base assembly. The base assembly includes: a heating element; a control component, the control component including a power connector and / or an electronic control board; and a housing assembly, including a bottom case, a heat insulation rib, and an annular support frame. The support frame is arranged on the upper edge of the bottom case and forms an assembly space with the bottom case. The heat insulation rib is arranged on the bottom wall of the bottom case and / or the lower surface of the support frame, and divides the assembly space into an assembly cavity and a heat insulation cavity that is annularly arranged outside the assembly cavity. The control component is arranged in the heat insulation cavity.
[0006] In the above cooking appliance, the heating element and the control component are respectively arranged in the assembly cavity and the heat insulation cavity. Most of the heat generated by the heating element during operation will gather in the assembly cavity, and the heat insulation rib can play a role in heat insulation, reducing the heat flowing from the assembly cavity to the heat insulation cavity, so that the temperature in the heat insulation cavity is not easy to rise, avoiding the temperature of the control component exceeding the standard and causing damage to the control component, ensuring that the power connector and the electronic control board located in the heat insulation cavity can be used normally, thereby ensuring the safety of the cooking appliance during use.
[0007] In one embodiment, the heat insulation rib includes a first heat insulation rib, and the first heat insulation rib protrudes upward from the bottom wall of the bottom case.
[0008] With this arrangement, the heat in the assembly cavity can only enter the heat insulation cavity through the gap between the end of the first heat insulation rib away from the bottom wall of the bottom case and the support frame, thereby reducing the heat flowing from the assembly cavity to the heat insulation cavity and lowering the temperature of the control component.
[0009] In one embodiment, the support frame includes a support portion and an extension portion that extends obliquely from the support portion toward the assembly cavity. The support portion is connected to the upper edge of the bottom case, and a second heat insulation rib is provided on one side of the extension portion facing the bottom wall of the bottom case.
[0010] With such an arrangement, the heat in the assembly cavity can only enter the heat insulation cavity through the gap between the end of the second heat insulation rib away from the extension portion and the bottom wall of the bottom case, thereby reducing the heat flowing from the assembly cavity toward the heat insulation cavity and lowering the temperature of the control component.
[0011] In one embodiment, the support frame includes a support portion and an extension portion that extends obliquely from the support portion toward the assembly cavity. The support portion is connected to the upper edge of the bottom case, and a second heat insulation rib is provided on one side of the extension portion facing the bottom wall of the bottom case. The first heat insulation rib and the second heat insulation rib are partially overlapped in the vertical direction and spaced apart in the horizontal direction.
[0012] With such an arrangement, the first heat insulation rib and the second heat insulation rib form multi-layer heat insulation. The heat in the assembly cavity needs to turn at the end of the first heat insulation rib away from the bottom wall of the bottom case and the end of the second heat insulation rib away from the extension portion before it can flow into the heat insulation cavity, thereby extending the heat dissipation path for the heat generated by the heating element to reach the control component and enhancing the heat insulation effect.
[0013] In one embodiment, the overlapping length of the second heat insulation rib and the first heat insulation rib in the vertical direction satisfies 0.5 mm to 40 mm.
[0014] With such an arrangement, the heat dissipation path for the heat generated by the heating element to reach the control component is extended as much as possible without increasing the size of the base assembly.
[0015] In one embodiment, the first heat insulation rib is located outside the second heat insulation rib, or the second heat insulation rib is located outside the first heat insulation rib.
[0016] With such an arrangement, the control component can be disposed in the area near the bottom wall of the bottom case and the side of the first heat insulation rib away from the heating element, or the control component can be disposed in the area near the extension portion and the side of the second heat insulation rib away from the heating element.
[0017] In one embodiment, heat dissipation holes and a heat insulation convex ring are provided on the bottom wall of the bottom case. The heat insulation convex ring is located in the assembly cavity. The housing assembly further includes a first heat insulation member. The first heat insulation member is located between the bottom wall of the bottom case and the heating element and is disposed on the heat insulation convex ring. The first heat insulation member, the heat insulation convex ring, and the bottom wall of the bottom case form a heat insulation space.
[0018] With such an arrangement, the first heat insulation member can reduce the downward conduction of the heat generated by the heating member during operation, and the heat insulation space can reduce the convection of hot and cold air, thereby reducing heat loss and improving the cooking effect; the heat in the heat insulation space can be dissipated through the heat dissipation holes, and the condensed water can also be discharged through the heat dissipation holes in a timely manner.
[0019] In one embodiment, it further includes a square heat insulation area, which is surrounded by a front side wall, a left side wall, a rear side wall and a right side wall connected end to end in sequence. The front side wall is arranged outside the heat insulation convex ring, or the front side wall coincides with at least one of the heat insulation ribs. A first wire passing hole is provided on the left side wall or the right side wall, and the rear side wall coincides with the side wall of the bottom case, or the rear side wall is arranged inside the side wall of the bottom case.
[0020] With such an arrangement, multiple layers of isolation are formed between the inside of the heat insulation area and the heating member through the heat insulation convex ring, the heat insulation ribs and the side walls of the heat insulation area. Except for the position where the first wire passing hole is opened, other positions of the heat insulation area are isolated from the heat insulation cavity and the assembly cavity, thereby reducing the heat flowing from the assembly cavity to the heat insulation area and lowering the temperature in the heat insulation area.
[0021] In one embodiment, the power connector or the electronic control board is arranged in the heat insulation area, and the connecting wire of the power connector or the electronic control board passes through the first wire passing hole and is arranged in the heat insulation cavity.
[0022] With such an arrangement, while ensuring that the power connector and the electronic control board can be normally electrically connected to the components arranged in the heat insulation cavity and the assembly cavity, the isolation effect on the power connector and the electronic control board is improved, and the working environment temperature and the self-temperature of the power connector and the electronic control board are reduced.
[0023] In one embodiment, the housing assembly further includes a second heat insulation member, which is arranged on the bottom wall of the bottom case, within the area surrounded by the heat insulation convex ring, and below the first heat insulation member.
[0024] With such an arrangement, the first heat insulation member and the second heat insulation member form multiple layers of heat insulation, improving the heat insulation effect on the bottom case. Description of the Drawings

Detailed implementation manners
[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

When a component is considered to be "arranged on" another component, it can be directly arranged on the other component or there may be an intermediate component at the same time. When a component is considered to be "fixed to" another component, it can be directly fixed to the other component or there may be an intermediate component at the same time.
[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the specification of this utility model are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.
[0038] Cooking appliances such as electric hot pots that heat the pot body through heating elements have relatively high temperatures during operation, usually reaching up to 300 °C. For control components such as power connectors or electronic control boards, their heat resistance is relatively low. The heat of the heating element easily enters the installation positions of the power connector or the electronic control board, easily causing the temperature of the control component to exceed the standard, resulting in damage to the control component and further causing safety problems. In the prior art, heat insulation is usually achieved through a reflector and mica sheet. However, due to the presence of many avoidance holes or wire passing holes on both the reflector and the mica sheet, there are still problems with poor heat insulation and safety.
[0039] To solve the above problems, as Figures 1 to 9 shown, this utility model provides a cooking appliance that can improve the heat insulation effect and reduce potential safety hazards.
[0040] As Figures 1 to 3 shown, specifically, the cooking appliance includes a base assembly 100 and a pot body 200. The pot body 200 is placed on the base assembly 100. The base assembly 100 includes a heating element 10, a control component 20, and a housing assembly 30. Among them: The control component 20 includes a power connector 21 and an electronic control board 22. The housing assembly 30 includes a bottom shell 34, a heat insulation rib 33, and an annular support frame 35. The support frame 35 is provided on the upper edge of the bottom shell 34 and forms an assembly space with the bottom shell 34. The heat insulation rib 33 is provided on at least one of the bottom wall of the bottom shell 34 and the lower surface of the support frame 35, and divides the assembly space into an assembly cavity 31 and a heat insulation cavity 32 that is annularly arranged outside the assembly cavity 31. The heating element 10 is provided in the assembly cavity 31; the control component 20 is provided in the heat insulation cavity 32.
[0041] In the cooking appliance provided by this utility model, the heating element 10 and the control component 20 are respectively provided in the assembly cavity 31 and the heat insulation cavity 32. Most of the heat generated by the heating element 10 during operation will gather in the assembly cavity 31, and the heat insulation rib 33 can play a role in heat insulation, reducing the heat flowing from the assembly cavity 31 to the heat insulation cavity 32, making it difficult for the temperature in the heat insulation cavity 32 to rise, avoiding the temperature of the control component 20 exceeding the standard and causing damage to the control component 20, and ensuring that the power connector 21 and the electronic control board 22 located in the heat insulation cavity 32 can be used normally, thereby ensuring the safety of the use of this cooking appliance.
[0042] Of course, the control component 20 may also only include a power connector 21 or only include an electronic control board 22 as needed.
[0043] As Figure 2 As shown, the bottom case 34 includes a bottom wall and an annular side wall connected to the bottom wall. The bottom wall and the side wall can be integrally formed for easy production and processing, or they can be separately provided and fixedly connected by welding, screws, snap connections, etc. to ensure the stability and reliability of the bottom case 34.
[0044] As Figure 2 and Figure 4 As shown, heat dissipation holes 341 and heat insulation convex rings 342 are provided on the bottom wall of the bottom case 34. The heat insulation convex ring 342 is located in the assembly cavity 31; the housing assembly 30 further includes a heat insulation member 37. The heat insulation member 37 includes a first heat insulation member 371. The first heat insulation member 371 is located between the bottom wall of the bottom case 34 and the heating member 10 and is disposed on the heat insulation convex ring 342. The first heat insulation member 371, the heat insulation convex ring 342, and the bottom wall of the bottom case 34 form a heat insulation space 38. The heat insulation convex ring 342 can further isolate the heating member 10 and the control component 20, and the first heat insulation member 371 can isolate the heating member 10 and the bottom case 34, reducing the heat generated by the heating member 10 during operation from conducting downward, and preventing the cables in the heat insulation space 38 from contacting the high-temperature heating member 10 and being damaged. Moreover, the heat insulation space 38 can reduce the convection of hot and cold air, thereby reducing heat loss, improving the cooking effect, and also preventing the temperature of the bottom case 34 from being too high to affect the user experience or damage the tabletop. The heat in the heat insulation space 38 can be dissipated through the heat dissipation holes 341 to further prevent the temperature of the bottom case 34 from rising; when condensed water is generated in the housing assembly 30, the condensed water can also be discharged through the heat dissipation holes 341 in time, preventing the condensed water from remaining in the housing assembly 30 and affecting the normal use of the components in the housing assembly 30.
[0045] As Figure 4 As shown, the heat insulation convex ring 342 can be convexly provided upward from the bottom wall of the bottom case 34, or can be convexly provided downward from the support frame 35; alternatively, the heat insulation convex ring 342 can also be connected to other components such as the heat insulation member 37, as long as it can form a heat insulation space 38 with the heat insulation member 37 and the bottom wall of the bottom case 34. The embodiments of the present invention do not make specific limitations here.
[0046] Moreover, the heat-insulating convex ring 342 can be the circular structure shown in the figure, or can be structures with regular or irregular shapes such as triangles, squares, ellipses, etc. Along the radial direction of the heat-insulating convex ring 342, the wall thickness of the heat-insulating convex ring 342 satisfies 0.5 mm to 5 mm, such as any value between 0.5 mm and 5 mm like 0.5 mm, 0.6 mm, 1 mm... 4 mm, 5 mm, etc., so as to avoid occupying too much space inside the housing assembly 30 while ensuring the heat-insulating effect. The number of the heat-insulating convex rings 342 can be 1, 2, 3, 4 or more. Multiple heat-insulating convex rings 342 can be concentrically arranged, and the sizes gradually increase from the inside to the outside to achieve multi-layer heat insulation, so as to enhance the heat-insulating effect on the bottom shell 34 and the control assembly 20.
[0047] As Figure 2 and Figure 4 shown, the housing assembly 30 further includes a reflector 39 located in the assembly cavity 31. The heating element 10 is arranged on the reflector 39. The heat-insulating member 37 further includes a second heat-insulating member 372. The second heat-insulating member 372 is arranged on the bottom wall of the bottom shell 34, within the enclosed area of the heat-insulating convex ring 342, and below the first heat-insulating member 371. The reflector 39 is used to reflect the heat radiated downward by the heating element 10 toward the cookware 200 to reduce heat loss and improve the cooking effect. The second heat-insulating member 372 can enhance the heat-insulating effect on the bottom shell 34. Moreover, the reflector 39, the first heat-insulating member 371, and the second heat-insulating member 372 form multi-layer heat insulation, which can enhance the heat-insulating effect on the bottom shell 34.
[0048] As Figure 2 , Figure 7 and Figure 9 shown, a plurality of terminal blocks 11 are arranged on the heating element 10. The first heat-insulating member 371 is provided with a plurality of first avoidance holes 3711 arranged in one-to-one correspondence with the terminal blocks 11. The reflector 39 is provided with a plurality of second avoidance holes 391 arranged in one-to-one correspondence with the plurality of first avoidance holes 3711, avoiding the first avoidance holes 3711 and the second avoidance holes 391 occupying too much area on the first heat-insulating member 371 and the reflector 39 to reduce heat transfer downward. The cables on components such as the power connector 21 and the electronic control board 22 can enter the heat-insulating space 38 and sequentially pass through the corresponding first avoidance holes 3711 and second avoidance holes 391 and then be electrically connected to the terminal blocks 11. The second heat-insulating member 372 can be set as a complete heat-insulating plate to prevent the heat generated by the heating element 10 during operation from affecting the bottom shell 34 through the second avoidance holes 391 and the first avoidance holes 3711.
[0049] As Figure 4 and Figure 6As shown, the first heat insulation member 371 and the second heat insulation member 372 can be made of heat insulation materials such as mica sheets or heat insulation cotton. Among them, the first heat insulation member 371 is preferably a mica sheet and is fixed to the reflector 39 by being crimped by other components or by means of screws, buckles, etc.; the second heat insulation member 372 is preferably heat insulation cotton and is fixed to the bottom wall of the bottom shell 34 by being crimped by other components or by means of back glue, screws, buckles, etc. The thickness of the first heat insulation member 371 is less than or equal to the thickness of the second heat insulation member 372. Specifically, the thickness of the first heat insulation member 371 satisfies 0.2 mm to 0.8 mm, such as any value between 0.2 mm and 0.8 mm like 0.2 mm, 0.3 mm... 0.7 mm, 0.8 mm, etc.; the thickness of the second heat insulation member 372 satisfies 0.5 mm to 8 mm, such as any value between 0.5 mm and 8 mm like 0.5 mm, 0.6 mm, 1 mm... 7 mm, 8 mm, etc.
[0050] Moreover, the distance between the first heat insulation member 371 and the second heat insulation member 372 satisfies 2 mm to 80 mm, such as any value between 2 mm and 80 mm like 2 mm, 3 mm, 4 mm... 79 mm, 80 mm, etc., and is preferably 6 mm to 22 mm, so as to avoid increasing the overall thickness of the housing assembly 30 while ensuring the heat insulation effect of the heat insulation space 38.
[0051] As Figure 5 shown, in one embodiment, the heat insulation rib 33 includes a first heat insulation rib 331 which protrudes upward from the bottom wall of the bottom shell 34. The first heat insulation rib 331 enables the heat in the assembly cavity 31 to enter the heat insulation cavity 32 only through the gap between one end of the first heat insulation rib 331 away from the bottom wall of the bottom shell 34 and the support frame 35, so that the size of the communication port between the assembly cavity 31 and the heat insulation cavity 32 is small, and the first heat insulation rib 331 also isolates and absorbs part of the heat, thereby being able to reduce the heat flowing from the assembly cavity 31 towards the heat insulation cavity 32, lower the temperature of the control assembly 20, avoid the temperature of the control assembly 20 rising and being damaged, and ensure the safety of the cooking appliance during use and the normal service life of the cooking appliance.
[0052] As Figure 5As shown, in another embodiment, the support frame 35 includes a support portion 351 and an extension portion 352 that extends obliquely from the support portion 351 toward the assembly cavity 31. The support portion 351 is connected to the upper edge of the bottom case 34. A second heat insulation rib 332 is provided on the side of the extension portion 352 facing the bottom wall of the bottom case 34. The second heat insulation rib 332 enables the heat in the assembly cavity 31 to enter the heat insulation cavity 32 only through the gap between the end of the second heat insulation rib 332 away from the extension portion 352 and the bottom wall of the bottom case 34, making the size of the communication port between the assembly cavity 31 and the heat insulation cavity 32 smaller. Moreover, the second heat insulation rib 332 can also isolate and absorb part of the heat, thereby reducing the heat flowing from the assembly cavity 31 toward the heat insulation cavity 32, lowering the temperature of the control assembly 20, preventing the temperature of the control assembly 20 from rising and being damaged, and ensuring the safety of the cooking appliance during use and the normal service life of the cooking appliance.
[0053] The second heat insulation rib 332 can also be separated from the outer wall of the heat insulation cavity 32. The second heat insulation rib 332 is located above the top wall, and part of the heat insulation cavity 32 is located on the side of the second heat insulation rib 332 away from the heating element 10; alternatively, the second heat insulation rib 332 is located on the side of the heat insulation cavity 32 close to the heating element 10, that is, the heat insulation cavity 32 is completely located on the side of the second heat insulation rib 332 away from the heating element 10.
[0054] As Figure 5 As shown, in another embodiment, the heat insulation rib 33 includes both a first heat insulation rib 331 and a second heat insulation rib 332. Among them, the first heat insulation rib 331 protrudes upward from the bottom wall of the bottom case 34, and a second heat insulation rib 332 is provided on the side of the extension portion 352 facing the bottom wall of the bottom case 34. The first heat insulation rib 331 and the second heat insulation rib 332 are partially overlapped in the vertical direction and arranged at intervals in the horizontal direction. The first heat insulation rib 331 and the second heat insulation rib 332 are arranged at intervals in the horizontal direction to form multi-layer heat insulation, and the heat in the assembly cavity 31 needs to turn at the end of the first heat insulation rib 331 away from the bottom wall of the bottom case 34 and the end of the second heat insulation rib 332 away from the extension portion 352 before it can flow into the heat insulation cavity 32, extending the path between the assembly cavity 31 and the heat insulation cavity 32, thereby extending the heat dissipation path for the heat generated by the heating element 10 to be transferred to the control assembly 20 and enhancing the heat insulation effect on control components 20 such as the power connector 21 and the electronic control board 22.
[0055] As Figure 5As shown, the overlapping length L in the vertical direction between the second heat insulation rib 332 and the first heat insulation rib 331 satisfies 0.5 mm to 40 mm. For example, any value between 0.5 mm and 40 mm such as 0.5 mm, 0.6 mm, 1 mm, 2 mm... 39 mm, 40 mm, etc. It can be understood that the longer the overlapping length L of the first heat insulation rib 331 and the second heat insulation rib 332 in the vertical direction, the longer the heat dissipation path for the heat generated by the heating element 10 to be transferred to the control assembly 20, and thus the less heat flows from the assembly cavity 31 into the heat insulation cavity 32. L ≤ 40 mm to avoid the dimensions of the first heat insulation rib 331 and the second heat insulation rib 332 in the vertical direction from being too large and increasing the size of the base assembly 100, and at the same time ensure that the cable of the heating element 10 can pass through the gap between the first heat insulation rib 331 and the second heat insulation rib 33 and enter the heat insulation cavity 32.
[0056] Among them, it can be that the first heat insulation rib 331 is located outside the second heat insulation rib 332. The control assembly 20 is preferably arranged in the area near the bottom wall of the bottom shell 34 and on the side of the first heat insulation rib 331 away from the heating element 10. The heat in the assembly cavity 31 needs to turn at the second heat insulation rib 332 and the first heat insulation rib 331 in sequence before it can enter the heat insulation cavity 32. Or it can be that the second heat insulation rib 332 is located outside the first heat insulation rib 331. The control assembly 20 is preferably arranged in the area near the extension part 352 and on the side of the second heat insulation rib 332 away from the heating element 10. The heat generated by the heating element 10 needs to turn at the first heat insulation rib 331 and the second heat insulation rib 332 in sequence before it can enter the heat insulation cavity 32.
[0057] Moreover, the thicknesses of both the first heat insulation rib 331 and the second heat insulation rib 332 satisfy 0.5 mm to 5 mm. For example, any value between 0.5 mm and 5 mm such as 0.5 mm, 0.6 mm, 1 mm... 4 mm, 5 mm, etc. While ensuring the heat insulation effect, it avoids occupying too much space inside the housing assembly 30.
[0058] As Figure 5 、 Figure 6 and Figure 8 shown, the base assembly 100 further includes a square heat insulation area 40. The heat insulation area 40 is surrounded by a front side wall, a left side wall, a rear side wall, and a right side wall that are connected end to end in sequence. A first wire passing hole 41 is provided on the left side wall or the right side wall. The front side wall and the rear side wall are parallel to the heat insulation rib 33 or parallel to the tangent of the heat insulation rib 33, and the left side wall and the right side wall are perpendicular to the heat insulation rib 33.
[0059] In the illustrated embodiment, the front sidewall is disposed outside the heat insulation convex ring 342, and the rear sidewall coincides with the sidewall of the bottom case 34. That is, the heat insulation area 40 is separately provided with a front sidewall and uses the sidewall of the bottom case 34 as the rear sidewall. Among them, both the first heat insulation rib 331 and the second heat insulation rib 332 are connected to the top wall, left sidewall, and right sidewall of the heat insulation area 40 to prevent the heat in the assembly cavity 31 from flowing into the heat insulation cavity 32 through the gap between the first heat insulation rib 331 and the heat insulation area 40 and the gap between the second heat insulation rib 332 and the heat insulation cavity 32. A multi-layer isolation is formed between the inside of the heat insulation area 40 and the heating element 10 through the heat insulation convex ring 342, the first heat insulation rib 331, the second heat insulation rib 332, and the respective sidewalls of the heat insulation area 40. And except for the position where the first wire passing hole 41 is opened, other positions of the heat insulation area 40 are isolated from the heat insulation cavity 32 and the assembly cavity 31, so as to further reduce the heat flowing from the assembly cavity 31 to the heat insulation area 40, lower the temperature in the heat insulation area 40, and ensure the heat insulation effect.
[0060] Of course, in other embodiments, the front sidewall can also coincide with at least one heat insulation rib 33, that is, use at least one heat insulation rib 33 as the front sidewall of the heat insulation area 40; or the rear sidewall can also be disposed inside the sidewall of the bottom case 34, that is, the heat insulation area 40 is separately provided with a rear sidewall.
[0061] As Figure 5 shown, since the power connector 21 and the electronic control board 22 have relatively high requirements for the working environment temperature, the power connector 21 or the electronic control board 22 is arranged in the heat insulation area 40, and the connecting wires of the power connector 21 or the electronic control board 22 pass through the first wire passing hole 41 and are arranged in the heat insulation cavity 32. Thus, while ensuring that the power connector 21 and the electronic control board 22 can be normally electrically connected to the components arranged in the heat insulation cavity 32 and the assembly cavity 31, the isolation effect on the power connector 21 and the electronic control board 22 is improved, and the working environment temperature and the self-temperature of the power connector 21 and the electronic control board 22 are reduced.
[0062] Among them, the first wire passing hole 41 is preferably arranged between the sidewall of the bottom case 34 and the heat insulation rib 33. The first heat insulation rib 331 and the second heat insulation rib 332 can isolate the heating element 10 and the first wire passing hole 41, and reduce the heat generated by the heating element 10 from entering the heat insulation area 40 through the first wire passing hole 41. At the same time, the first heat insulation rib 331 can also prevent the condensed water in the housing assembly 30 from entering the heat insulation area 40 through the first wire passing hole 41 and causing damage to the power connector 21 and the electronic control board 22.
[0063] As Figure 5As shown, the housing assembly 30 may further include a shielding rib 36 provided on the bottom case 34. The shielding rib 36 is located in front of the first wire passing hole 41 to at least partially shield the first wire passing hole 41. The shielding rib 36 can squeeze the cable passing through the first wire passing hole 41 to reduce the opening size of the first wire passing hole 41, thereby further reducing the heat entering the heat insulation area 40 through the first wire passing hole 41.
[0064] Further, heat insulation cotton (not shown in the figure) is provided on the inner wall or outer wall of the heat insulation area 40. The thickness of the heat insulation cotton satisfies 0.3 mm to 8 mm, such as any value between 0.3 mm and 8 mm, such as 0.3 mm, 0.4 mm, 1 mm... 7 mm, 8 mm, etc. The heat insulation cotton can further improve the heat insulation effect of the heat insulation area 40. The heat insulation cotton can be fixed to the inner wall or outer wall of the heat insulation area 40 by being crimped by other components or by means of back glue, screws, buckles, etc. Moreover, the heat insulation cotton can cover the first wire passing hole 41 to reduce the heat entering the heat insulation area 40 through the first wire passing hole 41.
[0065] Further, a through hole (not shown in the figure) may be opened at the bottom of the heat insulation area 40. The heat in the heat insulation area 40 can be dissipated through the through hole, further preventing the temperature of the power connector 21 and the electronic control board 22 from rising; when condensate is generated in the heat insulation area 40, the condensate can also be discharged in time through the through hole, preventing the condensate from remaining in the heat insulation area 40 and affecting the normal use of the power connector 21 and the electronic control board 22.
[0066] As Figure 1 shown, the cooking appliance can be set as an electric hot pot, an electric steamer, an electric stew pot, a rice cooker, etc., which are appliances that heat the pot body 200 through the heating element 10 of the base assembly 100. The embodiments of the present utility model are not specifically limited herein.
[0067] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0068] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
