Description

An air fryer

[0001] The present application claims priority to the Chinese patent application No. 202421524103.3, filed on June 28, 2024, and entitled "An air fryer", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of household appliances, and more particularly to an air fryer. BACKGROUND

[0003] With the pursuit of diversification and high efficiency of cooking by consumers, air fryers with two or even multiple independent or semi-independent cooking chambers are becoming increasingly popular. Each cooking chamber is equipped with an independent heating assembly to achieve the simultaneous or asynchronous heating of different food materials, thereby improving the cooking efficiency and achieving cooking flexibility.

[0004] However, in order to meet the design requirement of the overall compactness of the air fryer, multiple heating assemblies are often arranged in a relatively compact space or share part of the structure. When multiple heating assemblies work simultaneously for a long time, the hot air currents generated by each of them tend to converge in the area between them, causing local high temperature. In addition, the hot air currents may cause cross-talk. For example, the hot air current on one side affects the other side through the shell gap or the heat conduction of the internal structure, which destroys the preset hot air current path of the side, resulting in a decrease in the efficiency of the hot air current and affecting the cooking effect. SUMMARY

[0043] The present application will be further described in detail below with reference to the accompanying drawings.

[0044] Please refer to FIG. 1 to FIG. 3, the air fryer provided by the embodiments of the present application comprises a shell 100, one side of which is provided with a taking and placing opening 140. The air fryer further comprises an oven cavity shell 200 arranged in the shell 100, which defines an open cooking chamber 230. The cooking chamber 230 is in communication with the taking and placing opening 140 and the size of the opening thereof is adapted to the taking and placing opening 140. For example, the opening of the cooking chamber 230 coincides with the taking and placing opening 140. The cooking chamber 230 is used to accommodate a cooking container 500, for example, a draw-out cooking container 500. The cooking container 500 is placed in or taken out of the cooking chamber 230 through the taking and placing opening. The air fryer is further provided with an air guide shell 321 arranged in the shell 100. The air guide shell 321 is arranged in the upper half of the shell 100. The inner side of the air guide shell 321 is provided with a fan assembly 323, which rapidly blows the air heated by the heating element into the cooking container 500, forming a high-flow circulating hot air flow in the cooking container 500.

[0045] In some embodiments, the air fryer is equipped with two or even multiple cooking containers 500. The multiple cooking containers 500 are detachably arranged in the cooking chamber 230. The accompanying drawings take the air fryer equipped with two cooking containers 500 as an example to illustrate the technical solutions of the present application. Preferably, the two or even multiple cooking containers 500 are independent of each other. Correspondingly, two or even multiple fan assemblies 323 are arranged in the air guide shell 321. Preferably, the number of the cooking containers 500 is equal to the number of the fan assemblies 323. When each cooking container 500 is placed in the cooking chamber 230, the upper side of each cooking container 500 is provided with a corresponding fan assembly 323. The fan assembly 323 can form a hot air circulation path acting on its corresponding cooking container 500 from top to bottom when it is running. A partition plate 330 is arranged between adjacent fan assemblies 323. The partition plate 330 divides the working space of the adjacent fan assemblies 323 into independent parts.

[0046] In some embodiments, as shown in FIG. 8, the top of the air guide housing 321 is provided with an air inlet 3211. The bottom of the air guide housing 321 is provided with an air outlet 3212. The partition plate 330 is arranged between adjacent fan assemblies 323 and separates the working space of each fan assembly 323 into independent cavities. Preferably, the bottom of the partition plate 330 is lower than the air inlet 3211.

[0047] When the air fryer is working, the fan assembly 323 operates to cause the air outside the air guide housing 321 to flow into the air guide housing 321 through the air inlet 3211 and to flow out of the air guide housing 321 through the air outlet 3212. Since the partition plate 330 separates the working space of each fan assembly 323 from each other and the bottom of the partition plate 330 is lower than the air inlet 3211, each fan assembly 323 can form an independent air flow loop in its corresponding isolated cavity during operation. Thus, each fan assembly 323 can effectively drive the hot air flow inside its cavity and timely guide the hot air accumulated inside the housing 100 to the outside. In this way, the hot air flow discharged by adjacent fan assemblies 323 can be prevented from being superimposed on each other to cause local high temperature. Further, since the partition plate 330 completely separates the working space of the fan assemblies 323, the hot air flow discharged by the fan assemblies 323 is forced to be guided to circulate in the corresponding cooking container 500, effectively avoiding the hot air flow to diffuse disorderly in the cavity or enter the non-target cooking container, improving the thermal efficiency and avoiding uneven cooking effect.

[0048] In some embodiments, the number of air guide housings 321 is equal to the number of cooking containers 500, i.e., each cooking container 500 is provided with a corresponding air guide housing 321. The fan assembly 323 is arranged in its corresponding air guide housing 321 and located above its corresponding cooking container 500 to drive the hot air flow to circulate in the cooking container 500 during heating, thereby achieving a fast and uniform heating effect. Further, in order to avoid the interference of hot air flow between adjacent air guide housings 321 or the superposition of hot air flow in the area between the air guide housings 321 to cause local high temperature, the partition plate 330 is arranged between adjacent air guide housings 321. The partition plate 330 separates the working space of adjacent air guide housings 321 into independent hot air circulation flow channels. In this way, multiple fan assemblies 323 can work independently of each other, each driving the hot air flow in the corresponding air guide housing 321 to circulate, effectively preventing the hot air flow from being superimposed or stacked, further avoiding the risk of local high temperature caused by heat concentration, and improving the overall safety and working reliability of the air fryer.

[0049] In some embodiments, referring to FIGS. 2 and 3, the air fryer comprises two air guide housings 321. The two air guide housings 321 are spaced apart along the width direction of the housing 100 and separated by a partition 330. The partition 330 separates the respective working spaces of the two air guide housings 321 into two independent cavities within the housing 100. Meanwhile, each of the two air guide housings 321 is provided with a fan assembly 323. When the cooking containers 500 are placed in the cooking chamber 230, each of the cooking containers 500 is directly above a corresponding air guide housing 321, so that the fan assembly 323 can form a hot air circulation path acting on the corresponding cooking container 500 from top to bottom when the fan assembly 323 is in operation.

[0050] During the operation of the air fryer, the fan assembly 323 draws air outside the corresponding air guide housing 321 and drives the airflow into the cooking container 500 directly below the air guide housing 321, thereby driving the internal hot air circulation in the cavity. Due to the provision of the partition 330, each fan assembly 323 basically only affects the hot air flow in the corresponding cavity during operation, without causing interference or convergence of the hot air flow between the two fan assemblies 323, thereby achieving independent and efficient hot air driving.

[0051] In some embodiments, referring to FIG. 2, the top of the partition 330 is higher than the air inlet 3211, so that the partition 330 not only isolates the working spaces of the fan assemblies 323 in different air guide housings 321 from each other, but also forms a physical barrier for the hot air flow in the air inlet path.

[0052] During the operation of the air fryer, the fan assembly 323 drives the air outside the air guide housing 321 into the air guide housing 321 through the air inlet 3211 and flows into the corresponding cooking container 500, thereby forming a hot air circulation path. The top of the partition 330 is higher than the air inlet 3211, which can effectively prevent the air flow of one air guide housing 321 from entering another air guide housing 321 from above the air inlet 3211, thereby avoiding back suction of the hot air flow. Thus, the partition 330 not only separates each fan assembly 323 in a respective independent cavity, but also establishes a clear physical boundary in the air inlet path, so that each fan assembly 323 can more stably and effectively drive the hot air flow in the corresponding cavity.

[0053] In some embodiments, the capacities of the plurality of cooking containers 500 are the same. The plane where the partition 330 is located is vertically arranged with the plane where the air inlet 3211 is located. In this way, the air inlet 3211 is directed towards the top of the housing 100. The partition 330 uniformly separates each air guide housing 321 into an independent cavity. The plurality of air guide housings 321 are equally spaced apart along the width direction inside the housing 100.

[0054] In other embodiments, the plurality of cooking containers 500 have different capacities, and the partition plate 330 can also be inclined. That is, the partition plate 330 can be arranged as needed.

[0055] In some embodiments, the partition plate 330 is connected to the inner side of the shell 100. In this way, the partition plate 330 can be stably installed in the shell 100. The partition plate 330 separates each air guide housing 321 into a separate cavity, so as to reduce or avoid the existence of hot air flow between adjacent cavities. Therefore, the fan assemblies 323 on the inner side of each air guide housing 321 can work independently of each other, each driving the hot air flow in the corresponding air guide housing 321 to circulate, effectively preventing the hot air flow from flowing or superimposing, further avoiding the risk of local high temperature caused by heat concentration, improving the overall safety and working reliability of the air fryer. At the same time, each fan assembly 323 can preferably drive the hot air flow in the corresponding cavity, so as to timely take out the air flow on the inner side of the shell 100 and exhaust to the outside of the air fryer, thereby avoiding the risk of scalding the user due to the high temperature of the shell 100.

[0056] In some embodiments, the partition plate 330 is integrally arranged with the shell 100. In this way, the air fryer is more convenient to assemble. The partition plate 330 divides the working space of adjacent fan assemblies 323 into independent parts, and each fan assembly 323 can form a hot air circulation path acting from top to bottom on its corresponding cooking container 500 when running.

[0057] Of course, the partition plate 330 is assembled and connected with the shell 100, that is, the partition plate 330 and the shell 100 are two independent components, each component has a simple structure and is easy to manufacture.

[0058] Referring to FIGS. 3 and 5, the shell 100 is provided with air inlets 112 and air outlets 135. In some embodiments, the number of air outlets 135 is equal to the number of air guide housings 321. Each air guide housing 321 is arranged on the inner side of the shell 100, and the air inlet 3211 of each air guide housing 321 is in communication with the corresponding air inlet 112, and the air outlet 3212 of each air guide housing 321 is in communication with the corresponding air outlet 135.

[0059] During the working process of the air fryer, the fan assemblies 323 operate to introduce air outside the housing 100 into the housing 100 through the air inlets 112. After being heated by the heating elements in the housing 100, the air flow enters the inside of the air guide housings 321 through the air inlets 3211 and flows into the corresponding cooking containers 500, thereby forming a hot air circulation path, and finally being discharged from the air outlets 135. It can be understood that the partition plates 330 separate the air guide housings 321 into different cavities. In this way, on the one hand, the fan assemblies 323 can work independently of each other, each driving the hot air circulation in the corresponding air guide housing 321, effectively preventing the hot air from flowing together or superimposing, further avoiding the risk of local high temperature caused by heat concentration, and improving the overall safety and working reliability of the air fryer. On the other hand, the fan assemblies 323 can preferably drive the hot air in the corresponding cavities, so that the air in the external environment can quickly enter the housing 100 from the air inlets 112 and be discharged to the outside of the air fryer from the air outlets 135 under the action of the fan assemblies 323, thereby quickly cooling the housing 100 and avoiding scalding of the user due to the high temperature of the housing 100.

[0060] Further, referring to FIGS. 2 to 4, the air fryer further comprises a mounting bracket 310. The mounting bracket 310 is horizontally fixedly arranged at the top of the oven cavity housing 200 and forms the upper heat dissipation cavity 134 with the top of the housing 100. The air inlets 112 and the air outlets 135 are in communication with the upper heat dissipation cavity 134. The air guide housings 321 are arranged on the mounting bracket 310 and located in the upper heat dissipation cavity 134. The bottom of the partition plate 330 is connected with the mounting bracket 310, and the top of the partition plate 330 is connected with the inner side of the housing 100. The partition plate 330 is located between adjacent air guide housings 321 so that the air guide housings 321 are located in different cavities in the upper heat dissipation cavity 134. It can be understood that the partition plate 330 is connected with the air guide housings 321 and the mounting bracket 310 through the mounting bracket 310. In this way, the partition plate 330 separates the upper heat dissipation cavity 134 into multiple independent cavities for mounting the air guide housings 321. Therefore, the fan assemblies 323 in adjacent air guide housings 321 can work independently of each other, each driving the hot air circulation in the corresponding air guide housing 321, effectively preventing the hot air from flowing together or superimposing, further avoiding the risk of local high temperature caused by heat concentration, and improving the overall safety and working reliability of the air fryer. At the same time, the fan assemblies 323 can preferably drive the air flow in the corresponding cavities, so that the air in the external environment can quickly enter the housing 100 from the air inlets 112 and be discharged to the outside of the air fryer from the air outlets 135 under the action of the fan assemblies 323, thereby quickly cooling the housing 100 to avoid scalding of the user due to the high temperature of the housing 100.

[0061] In some embodiments, the partition 330 is integrally arranged with the mounting bracket 310, so that the air fryer is convenient to assemble. The partition 330 divides the working space of the adjacent fan assemblies 323 into independent parts, and due to the arrangement of the partition 330, each fan assembly 323 basically only affects the hot air flow in the corresponding cavity when working, and does not cause interference or convergence of the hot air flow between the two fan assemblies 323, thereby realizing independent and efficient hot air driving.

[0062] Of course, the partition 330 is assembled and connected with the shell 100, that is, the partition 330 is a component independent of the mounting bracket 310 and the shell, and each component structure is simple and convenient to manufacture.

[0063] In some embodiments, referring to FIGS. 2-5, the shell 100 includes a lower shell 110, a side shell 120, and an upper shell 130. The lower end of the side shell 120 is connected with the lower shell 110, and the upper end of the side shell 120 is connected with the upper shell 130. The side shell 120 is arranged in a substantially U shape, so that the side shell 120 forms a taking and placing opening 140 on one side thereof. Meanwhile, the oven cavity shell 200 includes a bottom plate 210 and a surrounding plate 220. The bottom plate 210 is arranged at the upper side of the lower shell 110 with a spacing therebetween to form a lower heat dissipation cavity 111. The bottom of the lower shell 110 is provided with an air inlet 112 which is in communication with the lower heat dissipation cavity 111. The surrounding plate 220 is arranged in a substantially U shape, and the surrounding plate 220 is arranged at the inner side of the side shell 120 with a spacing therebetween. The lower edge of the surrounding plate 220 is connected with the edge of the bottom plate 210, and the two are surrounded to form two cooking chambers 230 which are in communication with the taking and placing opening 140 on the side shell. The outer side of the surrounding plate 220 and the inner side of the side shell 120 form a U-shaped heat dissipation channel 121, and the lower end of the heat dissipation channel 121 is in communication with the lower heat dissipation cavity 111. The mounting bracket 310 is fixedly assembled at the top of the surrounding plate 220, and the mounting bracket 310 and the upper shell 130 form the above-mentioned upper heat dissipation cavity 134. Two air guide shells 321 are assembled and connected to the mounting bracket 310 and located at the inner side of the upper shell 130. The upper end of the heat dissipation channel 121 is in communication with the upper heat dissipation cavity 134. Meanwhile, the rear side of the upper shell 130 is provided with an air outlet 135, and the air outlet port 3212 (see FIG. 8) of the air guide shell 321 is arranged towards the air outlet 135.

[0064] Due to the arrangement of the partition plate 330, each fan assembly 323 only affects the hot air flow in the corresponding cavity during rotation, without causing interference or convergence of the hot air flow between the two fan assemblies 323, thereby achieving independent and efficient hot air driving. When the fan assembly 323 is working, the hot air flow flows from the air inlet 112 into the lower heat dissipation cavity 111 to prevent local high temperature of the lower shell 110, thereby avoiding scalding of the user by the lower shell 110. Then, the hot air flow flows from the lower heat dissipation cavity 111 into the heat dissipation channel 121, and from the upper port of the heat dissipation channel 121 into the upper heat dissipation cavity 134. Among them, when the hot air flow passes through the heat dissipation channel 121, the hot air flow prevents the side shell 120 from being heated to a high temperature to avoid scalding of the user by the side shell 120. Finally, after the hot air flow flows into the upper heat dissipation cavity 134, the hot air flow flows from the upper heat dissipation cavity 134 into the inner side of the air guide shell 321, and the fan assembly 323 discharges the hot air flow from the air outlet 3212 of the fan assembly 323, thereby being discharged from the air outlet 135 of the upper shell 130 to the outside of the upper shell 130. Among them, when the hot air flow passes through the upper heat dissipation cavity 134, the hot air flow prevents the upper shell 130 from being heated to a high temperature to avoid scalding of the user by the side shell 120.

[0065] It should be noted that the partition plate 330 divides the upper heat dissipation cavity 134 into two cavities, and the two air guide shells 321 are respectively located in the two cavities, and correspondingly, the fan assembly 323 respectively acts on the hot air flow in different spaces when the fan assembly 323 is running. In this way, during rotation of the fan assembly 323, the fan assembly 323 can drive the flow of hot air in the corresponding cavity, thereby the flow of hot air in the heat dissipation channel 121 can be driven, so that the hot air in the heat dissipation channel 121 can be brought into the upper heat dissipation cavity 134 in time, and discharged to the outside of the upper shell 130 by the fan assembly 323. As can be seen, through the arrangement of the partition plate 330, the flow of hot air in the heat dissipation channel 121 is effectively accelerated, so that the hot air in the heat dissipation channel 121 can timely take away the heat in the heat dissipation channel 121, thereby effectively avoiding scalding of the customer due to high temperature of the side shell 120.

[0066] Further, the upper shell 130 includes a contraction portion 131, an extension portion 132, and a cover plate portion 133. The contraction portion 131 and the extension portion 132 are both annular shells. The lower end of the contraction portion 131 is connected to the upper end of the side shell 120. The extension portion 132 is connected to the upper end of the contraction portion 131. The cover plate portion 133 is connected to the upper end of the extension portion 132. The air outlet 135 is arranged on the rear side of the contraction portion 131 and the extension portion 132. The contraction portion 131 is arranged inwardly, or in other words, the cross section of the contraction portion 131 is reduced. The cross section of the extension portion 132 is effectively reduced relative to the cross section of the side shell 120.

[0067] It can be understood that the cross section of the upper shell 130 is arranged in shrinkage relative to the cross section of the side shell 120, and the upper heat dissipation cavity 134 of the upper shell 130 is effectively lowered. Correspondingly, the size of the two cavities is effectively reduced, so that the fan assembly 323 can more effectively drive the hot air flow in the heat dissipation channel 121 and the upper heat dissipation cavity 134 during rotation, so as to timely discharge the heat in the heat dissipation channel 121 and the upper heat dissipation cavity 134 to the outside of the upper shell 130.

[0068] In some embodiments, the air fryer further comprises an inner lining frame 400 arranged inside the upper shell 130, used for mounting the control panel 430 and the circuit board 440.

The supporting plate 420 is fixedly arranged on the inner side of the inner lining ring 410, the supporting plate 420 has a first supporting plate portion 421 and a second supporting plate portion 422, and the second supporting plate portion 422 is arranged lower than the first supporting plate portion 421, the control panel 430 is arranged on the first supporting plate portion 421, and the circuit board 440 is arranged on the second supporting plate portion 422. It can be understood that the inner lining ring 410 of the inner lining frame 400 is fixedly arranged on the inner side of the extension portion 132, which can enhance the strength of the upper shell 130. In addition, the inner side of the inner lining frame 400 is provided with the supporting plate 420, which can be used for mounting the circuit board 440 and the control panel 430. Therefore, the inner lining frame 400 facilitates the installation of the control panel 430 and the circuit board 440.

[0069] In some embodiments, the partition plate 330 is integrally arranged with the inner lining. In this way, the air fryer is more convenient to assemble, and the partition plate 330 divides the working space of the adjacent fan assemblies 323 into independent parts, and each fan assembly 323 can form a hot air circulation path acting on the corresponding cooking container 500 from top to bottom when operating.

[0070] Of course, the partition plate 330 is assembled with the inner lining, that is, the partition plate 330 and the inner lining are two independent components, and each component has a simple structure and is convenient to manufacture.

[0071] In some embodiments, referring to FIG. 2, FIG. 3 and FIG. 6, the upper edge of the partition plate 330 is provided with a first accommodation gap 333 for accommodating the first supporting plate 420, so as to accommodate the circuit board 440 and / or the control panel 430 of the air fryer. Specifically, the first accommodation gap 333 is provided with a first gap portion 3331 and a second gap portion 3332, the second gap portion 3332 is arranged lower than the first gap portion 3331, the first gap portion 3331 is used for accommodating the first supporting plate portion 421, so as to accommodate the control panel 430, and the second gap portion 3332 is used for accommodating the second supporting plate portion 422, so as to accommodate the circuit board 440.

[0072] It can be understood that, by arranging the first accommodation gap 333, the control panel 430 and the circuit board 440 can be arranged at a lower position, so as to further compress the space of the upper heat dissipation cavity 134. Therefore, the fan assembly 323 can more effectively drive the hot air flow in the heat dissipation channel 121 and the upper heat dissipation cavity 134 during rotation, so as to timely discharge the heat in the heat dissipation channel 121 and the upper heat dissipation cavity 134 to the outside of the upper shell 130.

[0073] In some embodiments, referring to FIG. 2 and FIG. 6, the edge of the partition plate 330 is provided with a surrounding edge 331, so that the edge of the partition plate 330 is arranged in close contact with the inner side of the mounting bracket 310 and the outer shell 100 through the surrounding edge 331. It can be understood that, the edge of the partition plate 330 is arranged in close contact with the upper surface of the mounting bracket 310 and the inner wall of the outer shell 100 through the surrounding edge 331, so as to ensure the sealing of the connection of the partition plate 330, and thus the independence of the two cavities is ensured, so that the fan assembly 323 can more effectively drive the hot air flow in the heat dissipation channel 121 and the upper heat dissipation cavity 134 during rotation.

[0074] In some embodiments, the partition plate 330 is provided with reinforcing ribs 332 on both sides, and the two ends of the reinforcing ribs 332 are connected with the surrounding edge 331. For example, the reinforcing ribs 332 are vertically arranged, the lower end of the reinforcing ribs 332 is connected with the lower surrounding edge 331, and the upper end of the reinforcing ribs 332 is connected with the upper surrounding edge 331. It can be understood that, by arranging the reinforcing ribs 332, the reinforcing ribs 332 improve the strength of the partition plate 330, so as to ensure the sealing of the connection of the partition plate 330, and thus the independence of the two cavities is ensured.

[0075] In some embodiments, a mounting base 322 is arranged at the position of the air inlet 3211, the mounting base 322 comprises a mounting portion 3221 and an extension leg 3222 connected to each other, the mounting portion 3221 is located at the air inlet 3211, the extension leg 3222 is connected to the top of the air guide shell 321, and the base of the fan assembly 323 is assembled and connected to the mounting portion 3221. For the convenience of understanding, the air guide shell 321, the mounting base 322, and the fan assembly 323 can be understood as the burner 320 of the air fryer, and the partition plate 330 is used to separate each burner 320 in different cavities for work to achieve better air exhaust effect.

[0076] Further, the air guide ring 340 protruding upward is arranged at the position of the air inlet 3211, the air guide ring 340 is arranged at the side of the air inlet 3211, that is, the lower end of the air guide ring 340 is in communication with the air inlet 3211 of the air guide shell 321. Among them, the lower edge of the air guide ring 340 is provided with a third accommodation gap 342, and the extension leg 3222 can pass through the third accommodation gap 342 to be connected to the top of the air guide shell 321.

[0077] Among them, the air guide ring 340 and the upper shell 130 are independent components. Of course, according to the needs, the two can also be integrated.

[0078] It can be understood that the air guide ring 340 is arranged at the position of the air inlet 3211, so that the hot air flow in the heat dissipation channel 121 can flow along the inner wall of the upper shell 130 after flowing into the upper heat dissipation cavity 134, so as to flow into the air guide ring 340 from the upper end of the air guide ring 340, and flow into the air guide shell 321 from the air inlet 3211. Therefore, the hot air flow can effectively take away the heat accumulated in the upper heat dissipation cavity 134, so as to avoid the upper shell 130 being heated to a high temperature.

[0079] Moreover, the lower edge of the air guide ring 340 is provided with a third accommodation gap 342 for the extension leg 3222, so that the mounting base 322 can be conveniently assembled on the top of the air guide shell 321.

[0080] In addition, the air guide ring 340 is located inside the extension portion 132, and the cross section of the extension portion 132 is smaller than that of the side shell 120, so that the extension portion 132 further ensures the hot air flow to flow along the inner wall of the upper shell 130, thereby effectively taking away the heat in the upper shell 130.

[0081] Further, the end portion of the air guide ring 340 away from the air inlet 3211 is provided with a second accommodation gap 341 for accommodating the second supporting plate portion 422, thereby accommodating the circuit board 440 of the air fryer. It can be understood that, through the arrangement of the second accommodation gap 341, the circuit board 440 can be arranged at a lower position, thereby further compressing the space of the upper heat dissipation cavity 134. Therefore, the fan assembly 323 can more effectively drive the hot air flow in the heat dissipation channel 121 and the upper heat dissipation cavity 134 during rotation, thereby timely discharging the heat in the heat dissipation channel 121 and the upper heat dissipation cavity 134 to the outside of the upper shell 130.
