[0012] When the fan assembly is in operation, air from the external environment enters the first heat dissipation channel and / or the second heat dissipation channel through the air inlet and is discharged from the air outlet.

[0013] According to some embodiments of the present invention, a first thermal insulation gap is provided between the first thermal insulation board and the enclosure.

[0014] According to some embodiments of the present invention, the distance between the first heat insulation board and the enclosure board is set between 4 mm and 12 mm.

[0015] According to some embodiments of the present invention, the distance between the first heat insulation board and the enclosure is smaller than the distance between the first heat insulation board and the outer shell.

[0016] According to some embodiments of the present invention, edges of the first heat insulation board and / or the enclosure are provided with flanges, and the flanges seal the first heat insulation board and the enclosure.

[0017] According to some embodiments of the present invention, the air fryer includes a mounting bracket supporting the heating element, and an edge of the mounting bracket is fixedly arranged on the flange.

[0018] According to some embodiments of the present invention, the first heat insulation plate is a metal plate.

[0019] According to some embodiments of the present invention, the first heat insulation board is a galvanized board, or the side of the first heat insulation board close to the enclosure is configured as a high-gloss surface.

[0021] According to some embodiments of the present invention, the distance between the second thermal insulation board and the container partition is set between 4 mm and 12 mm.

[0022] According to some embodiments of the present invention, the distance between the second thermal insulation board and the container partition is smaller than the distance between the second thermal insulation board and the container panel.

[0023] According to some embodiments of the present invention, the upper and lower edges of the container partition are folded outward to form a fourth flange, the upper and lower edges of the second thermal insulation board are respectively fitted with the fourth flanges on the upper and lower sides, and the left and right edges of the second thermal insulation board are folded inward to form a fifth flange, and the fifth flange is fitted with the outer side of the container partition.

[0024] According to some embodiments of the present invention, the second heat insulation plate is a stainless metal plate.

[0025] According to some embodiments of the present invention, a side of the second heat insulation board close to the container partition is configured as a high-gloss surface.

[0026] It can be seen from the above technical solutions that the embodiments of the present application have the following advantages: when the heat dissipation gas passes through the first heat dissipation channel, it promptly takes away the heat in the first heat dissipation channel, thereby reducing the heat radiation to the outer shell, thereby preventing the temperature of the outer shell from being too high and causing burns to the user. At the same time, the first heat insulation plate is arranged on the outside of the enclosure, and the first heat dissipation channel is formed between the outer shell and the first heat insulation plate. With such an arrangement, the first heat insulation plate can effectively reduce the heat in the cooking chamber from being radiated to the outer shell, thereby further preventing the temperature of the outer shell from being too high and causing burns to the customer. In addition, the first heat insulation plate is wrapped around the outside of the enclosure, and the first heat insulation plate can effectively reduce the heat dissipated from the enclosure, thereby having a heat-insulating effect on the temperature of the cooking chamber. In this way, during the cooking process of the food in the cooking container, the cooking chamber has a sufficiently high heating temperature, thereby ensuring the cooking effect of the air fryer on the food.

[0027] Similarly, when the heat dissipating gas passes through the second heat dissipation channel, it promptly removes the heat in the second heat dissipation channel, thereby reducing the heat radiation to the container panel, thereby preventing the container panel from being too hot and causing burns to the user. At the same time, the second heat insulation plate is arranged on the outside of the container partition, and the second heat dissipation channel is formed between the container panel and the second heat insulation plate. With this arrangement, the second heat insulation plate can effectively reduce the heat in the cooking chamber from being radiated to the container panel, thereby further preventing the container panel from being too hot and causing burns to the customer. In addition, the second heat insulation plate is wrapped around the outside of the container partition, and the second heat insulation plate can effectively reduce the heat dissipated from the container partition, thereby having a heat-insulating effect on the temperature of the cooking chamber. In this way, during the cooking process of the food in the cooking container, the cooking chamber has a sufficiently high heating temperature, thereby ensuring the cooking effect of the air fryer on the food.

[0028] It should be noted that if the enclosure is used to enclose two cooking chambers, then when the first insulation board is applied to the outside of the enclosure, the first insulation board simultaneously insulates both cooking chambers, thereby ensuring that both cooking chambers maintain a relatively high temperature during the cooking process, thereby ensuring the cooking effect of the dual cooking container of the air fryer. Furthermore, if both cooking containers are provided with the second insulation board, the two cooking containers can effectively ensure that each cooking chamber has a good insulation effect, thereby ensuring that both cooking chambers maintain a relatively high temperature during the cooking process, thereby ensuring the cooking effect of the dual cooking container of the air fryer.

Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0044] The present invention will be further described in detail below with reference to the accompanying drawings.

[0045] See also Figures 1 to 3, an air fryer provided by an embodiment of the present invention includes an outer shell 100, a cavity shell 200, a cooking container 300, a first heat insulation plate 400 and / or a second heat insulation plate 500, wherein the outer shell 100 is provided with a take-out opening 140, and the outer shell 100 is provided with an air inlet 111 and an air outlet 121 communicating with the external environment; the cavity shell 200 includes a bottom plate 210 and a surrounding plate 220 arranged on the inner side of the outer shell 100, wherein the surrounding plate 220 is connected to the bottom plate 210 to enclose two or more cooking chambers 230, and the take-out opening 140 is connected to each cooking chamber 230; there are two or more cooking containers 300, that is, the number is equal to the number of cooking chambers 230, and the container body 310 of each cooking container 300 is placed in each cooking chamber 230 respectively to be able to cook the food in the container body 310. Each cooking container 300 includes a container body 310, a container partition 320, and a container panel 330. The container body 310 is used to be placed in the cooking chamber 230. The container partition 320 is disposed on the outside of the container body 310 and is used to close the access opening 140. The container panel 330 is disposed on the outside of the container partition 320. More specifically, the container panel 330 is disposed on the side of the container partition 320 away from the container body 310. A handle 340 is disposed on the outside of the container panel 330. The container panel 330 is disposed on the upper portion of the inner side of the housing 100, that is, corresponding to the top of the cooking chamber 230. The number of the container panels 330 is the same as that of the cooking containers 300, and is corresponding to the top of each cooking container 300. The first heat insulation plate 400 is arranged on the outside of the enclosure 220 and forms a first heat dissipation channel 130 between it and the side of the shell 100; and / or, the second heat insulation plate 500 is arranged on the outside of the container partition 320 and forms a second heat dissipation channel 331 between it and the container panel 330.

[0046] Each of the cooking containers 300 is provided with a fan assembly 620, and a heating element 630 is provided on the side of the fan assembly 620 facing the cooking container 300. For ease of understanding, the combination of the fan assembly 620 and the heating element 630 can be understood as a burner device 600. Therefore, a burner device 600 is correspondingly provided on the top of each cooking container 300.

[0047] When the fan assembly 620 is in operation, air from the external environment enters the first heat dissipation channel 130 and / or the second heat dissipation channel 331 through the air inlet, passes through the fan assembly 620, and is discharged from the air outlet 121. Furthermore, the fan assembly 620 causes part of the airflow to pass through the heating element 630 and enter the cooking container 300 to cook the food in the cooking container 300.

[0048] Also, according to actual needs, the air fryer may be provided with only the first insulation plate 400, or may be provided with only the second insulation plate 500. Of course, the air fryer can be provided with both the first insulation plate 400 and the second insulation plate 500, and this application is not limited to this.

[0049] During use, as the cooling gas passes through the first heat dissipation channel 130, it promptly removes heat from the first heat dissipation channel 130, thereby reducing heat radiation to the housing 100 and preventing the housing 100 from overheating and causing burns to the user. Furthermore, the first heat shield 400 is disposed outside the enclosure 220, with the first heat dissipation channel 130 formed between the housing 100 and the first heat shield 400. This arrangement effectively reduces the amount of heat from the cooking chamber 230 that radiates to the housing 100, further preventing the housing 100 from overheating and causing burns to the user. Furthermore, the first heat shield 400 wraps around the enclosure 220, effectively reducing heat dissipation from the enclosure 220 and maintaining a warm cooking chamber 230. This ensures that the food in the cooking container 300 remains heated to a sufficiently high temperature during cooking, ensuring the air fryer's cooking efficiency.

[0050] Similarly, as the cooling air passes through the second heat dissipation channel 331, it promptly removes heat from the second heat dissipation channel 331, thereby reducing the amount of heat radiated onto the container panel 330 and preventing the container panel 330 from overheating and potentially causing burns to the user. Furthermore, the second heat shield 500 is positioned outside the container partition 320, with the second heat shield 331 formed between the container panel 330 and the second heat shield 500. This arrangement effectively reduces the amount of heat radiated from the cooking chamber 230 onto the container panel 330, further preventing the container panel 330 from overheating and potentially causing burns to the user. Furthermore, the second heat shield 500 wraps around the container partition 320, effectively reducing the amount of heat dissipated from the container partition 320 and thus maintaining a warm cooking chamber 230. This ensures that the food in the cooking container 300 remains heated to a sufficiently high temperature during cooking, ensuring optimal cooking performance.

[0051] It should be noted that if the enclosure 220 is used to enclose two cooking chambers 230, then when the first insulation board 400 is applied to the outside of the enclosure 220, the first insulation board 400 simultaneously insulates both cooking chambers 230, thereby ensuring that both cooking chambers 230 maintain a relatively high temperature during the cooking process, thereby ensuring the cooking effect of the air fryer dual cooking container 300. Furthermore, if both cooking containers 300 are provided with the second insulation board 500, the two cooking containers 300 can effectively ensure that each cooking chamber 230 has a good insulation effect, thereby ensuring that both cooking chambers 230 maintain a relatively high temperature during the cooking process, thereby ensuring the cooking effect of the air fryer dual cooking container 300.

[0052] In some embodiments, reference Figure 2 and Figure 3 The inner side of the first heat insulating plate 400 and the outer side of the enclosure 220 are spaced apart from each other, thereby forming a first insulation gap between the inner side of the first heat insulating plate 400 and the outer side of the enclosure 220. Of course, the inner side of the first heat insulating plate 400 and the outer side of the enclosure 220 can also be arranged to fit together.

[0053] It will be appreciated that a first thermal insulation gap is formed between the first thermal insulation plate 400 and the enclosure 220. This first thermal insulation gap effectively retains heat dissipated from the enclosure 220, thereby reducing the amount of heat dissipated from the first thermal insulation plate 400 to the first heat dissipation channel 130. Furthermore, the heat retained by the first thermal insulation gap effectively reduces the amount of heat dissipated from the enclosure 220, thereby insulating the cooking chamber 230 and maintaining a suitable cooking temperature within the cooking chamber 230.

[0054] In some embodiments, the spacing between the first heat shield 400 and the enclosure 220 is set between 4 mm and 12 mm. For example, the spacing between the first heat shield 400 and the enclosure 220 is set to 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, etc. It is understood that the spacing between the first heat shield 400 and the enclosure 220 is set to at least 4 mm. This allows for a first thermal insulation gap of sufficient spacing to be formed between the first heat shield 400 and the enclosure 220. This first thermal insulation gap can effectively retain heat dissipated by the enclosure 220, thereby reducing the heat dissipated by the enclosure 220 and ensuring the cooking temperature of the cooking chamber 230. Furthermore, the spacing between the enclosure 220 and the housing 100 is subject to dimensional requirements during design. Typically, the spacing between the two should not exceed 25 mm. In this application, the spacing between the first heat shield 400 and the enclosure 220 should not exceed 12 mm. This provides a sufficient spacing between the side of the housing 100 and the first heat shield 400, thereby forming a first heat dissipation channel 130 of sufficient spacing. Therefore, a sufficient amount of cooling air can pass through the first heat dissipation channel 130, thereby ensuring that the heat in the first heat dissipation channel 130 can be taken out in time, thereby preventing the temperature of the housing 100 from being too high and scalding the user.

[0055] Furthermore, the spacing between the first heat shield 400 and the container panel 330 is set between 8 mm and 20 mm. For example, the spacing between the first heat shield 400 and the outer shell 100 is set to 8 mm, 14 mm, 16 mm, 20 mm, etc. It is understood that the spacing between the first heat shield 400 and the outer shell 100 is set to at least 8 mm, and there is a sufficient spacing between the side of the outer shell 100 and the first heat shield 400, thereby forming a first heat dissipation channel 130 with sufficient spacing. Therefore, the first heat dissipation channel 130 can pass a sufficient amount of cooling air, ensuring that heat in the first heat shield 130 is promptly dissipated, thereby preventing the outer shell 100 from overheating and causing burns to the user. Furthermore, the spacing between the first heat shield 400 and the outer shell 100 must not exceed 20 mm. This configuration allows the outer shell 100 and the first heat shield 400 to be assembled more compactly, thereby ensuring that the air fryer is not too large and making the air fryer more convenient to use.

[0056] The spacing between the first heat shield 400 and the enclosure 220 is smaller than the spacing between the first heat shield 400 and the container panel 330. It is understood that the spacing between the enclosure 220 and the housing 100 is subject to dimensional requirements during design, typically not exceeding 25 mm. The spacing between the first heat shield 400 and the enclosure 220 is smaller than the spacing between the first heat shield 400 and the container panel 330. Accordingly, there is a sufficient spacing between the side of the housing 100 and the first heat shield 400 to form a first heat dissipation channel 130 with sufficient spacing. Therefore, a sufficient amount of cooling air can pass through the first heat dissipation channel 130, ensuring that heat within the first heat dissipation channel 130 is promptly dissipated, thereby preventing the housing 100 from overheating and causing burns to the user.

[0057] The better the sealing effect of the first insulation gap, the better the insulation effect of the first insulation cavity. Therefore, in some embodiments, the edges of the first insulation board 400 and / or the enclosure 220 are provided with flanges, and the flanges seal the first insulation board 400 and the enclosure 220.

[0058] In one possible embodiment, referring to Figure 4 and Figure 5 The edge of the first heat insulating plate 400 is folded inward to form a first flange 410, and the edge of the enclosure 220 is folded outward to form a second flange 221. The first flange 410 and the second flange 221 are arranged in abutting relationship to form a closed first heat-insulating gap. For example, the upper and lower edges of the first heat insulating plate 400 both have inward-folded first flanges 410, and the upper and lower edges of the enclosure 220 both have outward-folded first flanges 410. The upper and lower first flanges 410 and the second flange 221 are in abutting relationship. As a result, the upper and lower edges of the first heat insulating plate 400 are sealed to the enclosure 220, thereby ensuring a relatively closed first heat-insulating gap is formed between the first heat insulating plate 400 and the enclosure 220, thereby effectively insulating the cooking chamber 230.

[0059] In other possible embodiments, the edge of the first insulation board 400 is folded inwardly to form a first flange 410, which is affixed to the outer sidewall of the enclosure 220. Thus, the first insulation board 400 is sealed and connected to the enclosure 220 to form a closed first insulation gap. Alternatively, the edge of the enclosure 220 is folded outwardly to form a second flange 221, which is affixed to the inner sidewall of the first insulation board 400. Thus, the first insulation board 400 is sealed and connected to the enclosure 220 to form a closed first insulation gap.

[0060] Furthermore, the first flange 410 is provided with a first connection hole (not shown), and the second flange 221 is provided with a second connection hole (not shown). Locking members (not shown) are inserted through and fixed to the first and second connection holes. The locking members can be screws or rivets, etc. This arrangement firmly secures the first heat sink to the outside of the enclosure 220. Furthermore, the locking members ensure that the first flange 410 and the second flange 221 fit tightly together, thereby ensuring the sealing of the first insulation gap.

[0061] In a further embodiment, referring to Figures 4 to 6 The air fryer includes a mounting bracket 700. A third flange 710 is provided on the edge of the mounting bracket 700. The third flange 710 is fixedly disposed between the first flange 410 and / or the second flange 221. For example, the third flange 710 is fixedly disposed between the first flange 410 and the second flange 221 to improve the sealing between the first flange 410 and the second flange 221. Furthermore, a locking member is provided through and fixed to the first flange 410, the second flange 221, and the third flange 710, thereby horizontally securing the mounting bracket 700 to the top of the enclosure 220. The mounting bracket 700 is used to mount two burner assemblies 600. The two burner assemblies 600 are respectively disposed at the tops of the two cooking chambers 230. The burner assemblies 600 provide hot air flow to the cooking chambers 230 and exhaust heat from the interior of the housing 100.

[0062] In some embodiments, reference Figure 2 and Figure 3 , the first heat insulation board 400 is roughly U-shaped. Specifically, the enclosure 220 is usually set to a U-shape, and the two ends of the first heat insulation board 400 extend to the left and right sides of the access opening 140 respectively. In the present application, the first heat insulation board 400 is roughly U-shaped. When the first heat insulation board 400 is applied to the outside of the enclosure 220, the two ends of the first heat insulation board 400 also extend to the left and right sides of the access opening 140. As a result, the first heat insulation board 400 can be fully wrapped around the outside of the enclosure 220, thereby having a good heat preservation effect on the cooking chamber 230, thereby ensuring the cooking effect of the air fryer double cooking container 300.

[0063] In some embodiments, the first heat insulation board 400 can be a metal board, for example, a galvanized board, which has good heat insulation effect and low cost. Of course, the first heat insulation board 400 can also be other heat insulation boards with high temperature resistance and heat preservation effect.

[0064] In one possible embodiment, the first heat insulation board 400 is a metal board, and the side of the first heat insulation board 400 close to the enclosure 220 is configured as a high-gloss surface. The high-gloss surface is a relatively smooth surface, which can be a characteristic of the material of the first heat insulation board 400 itself, or it can be a high-gloss surface formed by polishing the first heat insulation board 400. It is understandable that, by setting the high-gloss surface of the first heat insulation board 400, during the cooking process, when the high-gloss surface of the first heat insulation board 400 receives heat emitted by the enclosure 220, it can effectively radiate part of the heat back to the enclosure 220, thereby reducing the heat dissipation to the first heat dissipation channel 130, further improving the thermal insulation effect of the first heat insulation board 400.

[0065] In some embodiments, reference Figures 2 to 4 The bottom plate 210 is spaced apart from the bottom of the housing 100, forming a lower heat dissipation cavity 110 therebetween. An air inlet 111 is provided at the bottom of the housing 100, communicating with the lower heat dissipation cavity 110. The air fryer further includes two burner devices 600, each disposed at the top of the cooking chamber 230. An upper heat dissipation cavity 120 is formed between the burner cavity assembly and the top of the housing 100. An air outlet 121 is provided at the rear side of the top of the housing 100, with the exhaust port of the burner device 600 facing toward the outlet 121. The lower cavity communicates with the upper cavity via the first heat dissipation channel 130 and / or the second heat dissipation channel 331. Thus, heat dissipation gas can flow from the lower heat dissipation cavity 110 to the upper heat dissipation cavity 120 through the first heat dissipation channel 130 and / or the second heat dissipation channel 331.

[0066] Each fan assembly 620 includes a cooling fan 621 and a heating fan 622, mounted on the aforementioned mounting bracket 700. An air inlet is provided at the top of the housing 100 to communicate with the upper heat dissipation chamber 120, and an exhaust outlet is provided on the side of the housing 100. The cooling fan 621 and the heating fan 622 are mounted on the inner side of the housing 100. The cooling fan 621 directs cooling air from the air inlet to the exhaust outlet, thereby discharging the heat dissipated air outside the housing 100 through the air outlet 121. A heating element 630 is mounted on the side of the heating fan 622 facing the cooking container 300. The heating fan 622 is used to provide a circulating hot air flow to the cooking chamber 230 to cook the food in the cooking container 300.

[0067] During specific use, under the action of the cooling fan 621, cooling air flows from the air inlet 111 into the lower cooling chamber 110. From the lower cooling chamber 110, the cooling air flows toward the first cooling channel 130 and the second cooling channel 331, and then flows through the first cooling channel 130 and the second cooling channel 331 to the upper cooling chamber 120. The cooling air flows into the housing 100 through the air inlet and is discharged toward the air outlet 121 through the air outlet. Thus, the cooling air is discharged from the air outlet 121 to the outside of the housing 100. It is understood that the cooling air, as it passes through the lower cooling chamber 110, the first cooling channel 130, the second cooling channel 331, and the upper cooling chamber 120, promptly removes heat from the inside of the housing 100 and the container panel 330, preventing burns to the user from the housing 100 and the container panel 330.

[0068] Furthermore, an upwardly protruding air guide ring 640 is provided at the top of the air inlet. After the heat dissipation gas enters the upper heat dissipation cavity 120, the heat dissipation gas needs to flow into the air guide ring 640 through the upper port of the air guide ring 640, and then flow along the air guide ring 640 to the air inlet, thereby flowing into the inner side of the.

[0069] The air guide ring 640 is integrally provided, or the air guide ring 640 is connected to the assembly.

[0070] It can be understood that through the setting of the air guide ring 640, after the heat dissipation gas enters the upper heat dissipation cavity 120, the heat dissipation gas needs to adhere to the inner surface of the top of the shell 100 and flow toward the upper port of the air guide ring 640, thereby ensuring that the heat dissipation gas can fully remove the heat from the inner top of the shell 100.

[0071] In some embodiments, reference Figure 3 and Figure 7 The inner side of the second thermal insulation board 500 is spaced apart from the outer side of the container partition 320, thereby forming a second thermal insulation gap between the inner side of the second thermal insulation board 500 and the outer side of the container partition 320. Of course, the inner side of the second thermal insulation board 500 and the outer side of the container partition 320 can also be arranged to fit together.

[0072] It will be appreciated that a second thermal insulation gap is formed between the second thermal insulation plate 500 and the container partition 320. This second thermal insulation gap effectively retains heat dissipated from the container partition 320, thereby reducing the amount of heat dissipated through the second thermal insulation plate 500 to the second heat dissipation channel 331. Furthermore, the heat retained by the second thermal insulation gap effectively reduces the amount of heat dissipated from the container partition 320, thereby insulating the cooking chamber 230 and maintaining a suitable cooking temperature within the cooking chamber 230.

[0073] In some embodiments, the distance between the second thermal insulation plate 500 and the container partition 320 is set between 4 mm and 12 mm. For example, the distance between the second thermal insulation plate 500 and the container partition 320 is set to 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, etc. It is understood that the distance between the second thermal insulation plate 500 and the container partition 320 is set to at least 4 mm. A second thermal insulation gap with sufficient distance can be formed between the second thermal insulation plate 500 and the container partition 320. The second thermal insulation gap can effectively retain the heat dissipated by the container partition 320, thereby reducing the heat dissipated by the container partition 320 and ensuring the cooking temperature of the cooking chamber 230. Furthermore, the spacing between the container partition 320 and the container panel 330 is subject to dimensional requirements during design. Typically, the spacing between the two should not exceed 25 mm. In this application, the spacing between the second heat shield 500 and the container partition 320 should not exceed 12 mm. This arrangement creates a sufficiently large gap between the side of the container panel 330 and the second heat shield 500, thereby forming a second heat dissipation channel 331 with sufficient spacing. Therefore, a sufficient amount of cooling air can pass through the second heat dissipation channel 331, ensuring that heat in the second heat dissipation channel 331 is promptly dissipated, thereby preventing the container panel 330 from overheating and causing burns to the user.

[0074] Furthermore, the spacing between the second heat shield 500 and the container panel 330 is set between 8 mm and 20 mm. For example, the spacing between the second heat shield 500 and the container panel 330 is set to 8 mm, 14 mm, 16 mm, 20 mm, etc. It is understood that the spacing between the second heat shield 500 and the container panel 330 is set to at least 8 mm, and there is a sufficient spacing between the side of the container panel 330 and the second heat shield 500, thereby forming a second heat dissipation channel 331 with sufficient spacing. Therefore, the second heat dissipation channel 331 can pass a sufficient amount of cooling air, ensuring that heat in the second heat dissipation channel 331 is promptly dissipated, thereby preventing the container panel 330 from overheating and causing burns to the user. Furthermore, the spacing between the second heat shield 500 and the container panel 330 must not exceed 20 mm. This configuration allows the container panel 330 and the second heat shield 500 to be assembled more compactly, ensuring that the air fryer is not too large, making the air fryer more convenient to use.

[0075] The spacing between the second thermal insulation plate 500 and the container partition 320 is smaller than the spacing between the second thermal insulation plate 500 and the container panel 330. It is understood that the spacing between the container partition 320 and the container panel 330 is subject to dimensional requirements during design, typically not exceeding 25 mm. The spacing between the second thermal insulation plate 500 and the container partition 320 is smaller than the spacing between the second thermal insulation plate 500 and the container panel 330. Accordingly, there is a sufficient spacing between the side of the container panel 330 and the second thermal insulation plate 500, thereby forming a second heat dissipation channel 331 with sufficient spacing. Therefore, a sufficient amount of cooling air can pass through the second heat dissipation channel 331, ensuring that heat in the second heat dissipation channel 331 is promptly dissipated, thereby preventing the container panel 330 from overheating and causing burns to the user.

[0076] The better the sealing effect of the second insulation gap is, the better the insulation effect of the second insulation cavity is. Therefore, in one possible embodiment, referring to Figure 7 and Figure 8 The upper and lower edges of the container partition 320 are folded outward to form fourth flanges 321. The lower fourth flange 321 is connected to the lower edge of the container panel 330, and the upper fourth flange 321 is connected to the upper edge of the container panel 330. The upper and lower fourth flanges 321 define ventilation openings: a lower ventilation opening 3211 and an upper ventilation opening 3212. The lower ventilation opening 3211 communicates with the lower heat dissipation chamber 110, while the upper ventilation opening 3212 communicates with the upper heat dissipation chamber 120. As a result, cooling air from the lower heat dissipation chamber 110 can flow to the upper heat dissipation chamber 120 through the second heat dissipation channel 331. At the same time, the upper and lower edges of the second insulation plate 500 are respectively fitted with the fourth flanges 321 arranged on the upper and lower sides, and the left and right edges of the second insulation plate 500 are folded inward with a fifth flange 510, and the fifth flange 510 is fitted with the outer side of the container partition 320. Thus, the edge of the second insulation plate 500 is sealed and connected to the container partition 320, thereby ensuring that the second insulation gap has better sealing properties, and further ensuring that the second insulation cavity has a better insulation effect on the cooking chamber 230.

[0077] In some embodiments, the second heat shield 500 may be a stainless metal plate, for example, a stainless iron plate or a stainless steel plate, which has good heat insulation effect, low cost, and will not rust after cleaning. Of course, the second heat shield 500 may also be other heat shields that are resistant to high temperatures and have heat preservation effects.

[0078] In one possible embodiment, the second insulation plate 500 is a metal plate, and the side of the second insulation plate 500 proximal to the container partition 320 is configured as a high-gloss surface. The high-gloss surface is a relatively smooth surface that can be a characteristic of the material of the first insulation plate 400 itself, or it can be a high-gloss surface formed by polishing the first insulation plate 400. It is understood that the high-gloss surface of the second insulation plate 500 allows the high-gloss surface of the second insulation plate 500 to effectively radiate some of the heat emitted by the container partition 320 back to the container partition 320 during the cooking process, thereby reducing the amount of heat dissipated to the second heat dissipation channel 331 and further improving the thermal insulation effect of the second insulation plate 500.
