Description

Technical Field

[0001] This utility model relates to the field of air fryers, specifically an air fryer heat dissipation structure and a double-layer air fryer. Background Technology

[0002] An air fryer is a kitchen appliance that heats and frys food by heating air and using a fan to create hot airflow. In existing technology, an air fryer includes a main body and a frying pot body installed inside the main body. A fan device is installed above the inner pot, comprising a hot air fan that blows air into the inner pot to create a hot airflow for heating and frying, and a cooling fan that blows air into the main body and drives the airflow through air inlets and outlets on the outer shell of the main body to exchange heat with the outside of the main body for cooling.

[0003] The air fryer body consists of a control panel and the fryer itself. The fryer is used to hold food in the inner pot, while the control panel covers the open side of the inner pot of the body. When the air fryer is cooking, the surface temperature is lowered because the body has a heat dissipation function. However, the control panel of the fryer body does not have a heat dissipation structure. Therefore, as the fryer body heats up continuously, the heat is transferred to the control panel, causing the surface temperature to rise to a point where it is too hot to touch. This makes it difficult for users to remove the air fryer body after cooking and also increases the risk of burns from touching the control panel. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a heat dissipation structure for an air fryer and a double-layer air fryer.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An air fryer cooling structure includes an inner liner disposed within the main body, with an opening on the side of the main body for inserting the air fryer body into the inner liner. Above the opening is a control panel compartment formed by a horizontal protrusion of the main body. The air fryer body includes a panel and an air fryer. After the air fryer is inserted into the inner liner, its panel closes the opening, and the top of the panel is joined to the bottom of the control panel compartment. The main body has a cavity for accommodating a fan device and electronic control components, located above the inner liner. The electronic control components are disposed within the control panel compartment. The fan device is disposed at the top of the inner liner and includes a cooling fan and a hot air fan. The machine body is equipped with an air inlet and a heat dissipation exhaust outlet. The heat dissipation fan blows air from outside the machine body into the receiving cavity through the air inlet and out through the heat dissipation exhaust outlet, carrying away the heat inside the receiving cavity. The hot air fan circulates air into the inner liner, forming a circulating hot airflow. The bottom of the control panel compartment is equipped with a top ventilation opening that communicates with the receiving cavity. The panel of the fryer body is equipped with a ventilation channel I. The top of the panel is equipped with an air inlet I that connects to the top ventilation opening, so that the ventilation channel I communicates with the receiving cavity. The side of the panel that connects to the fryer is equipped with an air outlet, so that the ventilation channel I communicates with the inner liner.

[0007] The air outlet is located on the lower side of the panel, near the bottom of the fryer.

[0008] The panel includes a front cover and a frame. The back of the frame is provided with a mounting base for connecting the fryer. The front cover covers the front of the frame, and the ventilation channel I is formed between the front cover and the frame. The air inlet I is located at the top of the frame, and the air outlet is located at the back of the frame.

[0009] The frame has a viewing window in the middle, the fryer has a viewing window on the side wall corresponding to the viewing window, the front cover is made of a light-transmitting material, and the air outlet is located below the viewing window.

[0010] The bottom of the panel is also provided with an air inlet II that connects to the outside and ventilation channel I.

[0011] The cross-sectional area of ​​the air inlet II is larger than the cross-sectional area of ​​the air outlet.

[0012] The body extends to the bottom of the opening to form a support platform. After the fryer body is inserted into the opening, the panel is placed on the support platform. The support platform is also provided with a through bottom ventilation port corresponding to the air inlet II.

[0013] A double-layer air fryer includes a body with upper and lower fryer bodies. The inner liner of the body is divided into an upper cooking chamber and a lower cooking chamber. The upper and lower cooking chambers have openings on the same side for inserting the upper and lower fryer bodies into each other. The upper cooking chamber and the upper fryer body adopt the above-mentioned air fryer heat dissipation structure. The bottom of the panel of the upper fryer body is provided with an air inlet II. The lower panel of the lower fryer body is provided with a ventilation channel II and a connecting port I at the top that connects to the air inlet II. A connecting port II at the bottom connects to the outside, so that the ventilation channel II connects to the ventilation channel I in the panel of the upper fryer body and connects to the outside atmosphere.

[0014] The beneficial effects of this utility model are as follows: The panel of the fryer body of this utility model is provided with a ventilation channel I, which is connected to the housing cavity inside the body with a cooling fan through the air inlet I at the top. The cooling fan creates suction between the housing cavity and the ventilation channel I, which removes the heat inside the panel. At the same time, the ventilation channel I is connected to the inner liner through the air outlet. The circulating airflow generated in the inner liner by the hot air fan also creates suction between the ventilation channel I and the panel, further removing the heat inside the panel. The surface temperature of the panel is quickly reduced through the dual suction air path, solving the problem of overheating of the panel of the existing fryer body. Attached Figure Description

[0022] Reference Figures 1 to 3An air fryer cooling structure includes an inner liner 2 housed within a body 1. The body 1 has an opening on its side for inserting the fryer body into the inner liner 2. Above the opening is a control panel compartment 13 formed by a horizontal protrusion of the body 1. The fryer body includes a panel 31 and a fryer 32. After the fryer 32 is inserted into the inner liner 2, its panel 31 closes the opening, and the top of the panel 31 engages with the bottom of the control panel compartment 13. The body 1 has a cavity 14 for housing a fan device 4 and an electronic control component 5, located above the inner liner 2. The electronic control component 5 is housed within the control panel compartment 13, and its operation panel is located on the side or top of the control panel compartment 13. The fan device 4 is located on the top of the inner liner 2 and includes a cooling fan 41 and a hot air fan 42. The main body 1 is equipped with an air inlet and a heat dissipation exhaust vent 12. A cooling fan 41 blows air from outside the main body 1 into the receiving cavity 14 through the air inlet and out through the heat dissipation exhaust vent 12, carrying away the heat inside the receiving cavity 14. A hot air fan 42 circulates air into the inner liner 2, forming a circulating hot airflow. The bottom of the control panel compartment 13 is equipped with a top ventilation vent 15 that communicates with the receiving cavity 14. The panel 31 of the fryer body is equipped with a ventilation channel I 33. The top of the panel 31 is equipped with an air inlet I 34 that connects to the top ventilation vent 15, so that the ventilation channel I 33 communicates with the receiving cavity 14. The cooling fan 41 circulates air, causing the receiving cavity 14 to generate suction relative to the ventilation channel I 33, carrying away the heat inside the panel 31. At the same time, an air outlet 35 is provided on the side of the panel 31 that connects to the fryer 32, so that the ventilation channel I 33 communicates with the inner liner 2. The circulating airflow generated in the inner liner 2 by the hot air fan 42 also generates suction relative to the ventilation channel I 33, further carrying away the heat inside the panel 31. By using a dual-suction air path to quickly reduce the surface temperature of panel 31, the problem of overheating of the fryer body panel in existing technology is solved.

[0023] As a preferred embodiment of this utility model, the air outlet 35 is arranged below the side of the panel 31 near the bottom of the fryer 32, so that the ventilation channel I 33 is connected to the inner pot 2 near the bottom of the inner pot 2, which reduces the interference with the air intake I 34 at the top and the suction airflow of the receiving cavity 14, effectively improves the airflow and enhances the heat dissipation effect.

[0024] like Figure 1 As shown, in order to enhance the airflow of panel 31 and thus improve the heat dissipation effect, panel 31 is also provided with an air inlet II 36 at the bottom, which connects the outside and the ventilation channel I 33. Through the suction brought by the air outlet 35, a large amount of cold air from the outside is drawn in from the air inlet II 36. The cross-sectional area of ​​the air inlet II 36 is preferably larger than the cross-sectional area of ​​the air outlet 35, so that the top ventilation vent 15 can also draw in cold air from the outside from the bottom, allowing the air entering from the outside to circulate throughout the entire ventilation channel I 33, further improving the heat dissipation effect.

[0025] Preferably, when the above-mentioned fryer body is applied to a common single-layer air fryer, in order to ensure the installation stability of the fryer body, the body 1 extends to the bottom of the opening to form a support platform 16. After the fryer body is inserted into the opening, the panel 31 is placed on the support platform 16. The support platform 16 is also provided with a through bottom ventilation port 17 corresponding to the air inlet II 36, so that the air inlet II 36 can be connected to the outside.

[0026] like Figure 2 , Figure 3 As shown, this is the first embodiment of the fryer body. The specific structure of the panel 31 mainly includes a front cover 311 and a frame 312. The back side of the frame 312 is provided with a mounting seat 313 for connecting the fryer 32. The front cover 311 covers the front side of the frame 312. A ventilation channel I 33 is formed between the front cover 311 and the frame 312. The air inlet I 34 is located at the top of the frame 312, and the air outlet 35 is located on the back side of the frame 312.

[0027] like Figure 4 , Figure 5 As shown, this is the second embodiment of the air fryer body. A viewing window 314 can be provided in the middle of the frame 312. A viewing window 321 corresponding to the viewing window 314 is provided on the side wall of the air fryer 32. The front cover 311 is made of a light-transmitting material, so that the food inside the air fryer can be observed from the outside when the air fryer is working. The air outlet 35 is located below the viewing window 314.

[0028] The above-mentioned heat dissipation structure can be widely used in different types of air fryers, such as Figure 1 The single-layer air fryer shown is more suitable for applications such as... Figure 6 In a double-layered air fryer, the dual-layer arrangement allows for better heat dissipation. For example... Figure 1As shown, the double-layer air fryer includes a body 1 with upper and lower fryer bodies. The inner liner 2 inside the body 1 is divided into an upper cooking chamber 21 and a lower cooking chamber 22. The upper cooking chamber 21 and the lower cooking chamber 22 have openings on the same side for inserting the upper fryer body 3 and the lower fryer body 30 into the chamber. The upper cooking chamber 21 and the upper fryer body 3 adopt the aforementioned air fryer heat dissipation structure. In order to achieve heat dissipation of the lower panel 301 of the lower fryer body 30 through the aforementioned air fryer heat dissipation structure, the panel 31 of the upper fryer body 3 also has an air inlet II 36 at the bottom. The lower panel 301 of the lower fryer body 30 has a ventilation channel II 303 and a connecting port I 304 at the top that connects to the air inlet II 36. It also has a connecting port II 305 at the bottom that connects to the outside. II303 connects to the ventilation channel I33 inside the panel of the upper fryer body 3 and to the outside atmosphere. When the upper cooking cavity 21 is working, the suction force generated by the hot air circulation in the upper cooking cavity 21 on the ventilation channel I33 inside the panel 31 of the upper fryer body 3 also acts on the ventilation channel II303 connected to the ventilation channel I33. The cold air from the outside atmosphere enters the ventilation channel II303 from the connecting port II305 at the bottom of the lower panel 301, flows through the entire ventilation channel II303, and then enters the ventilation channel I33 through the connecting port I304 and enters the upper cooking cavity 21. At this time, the lower panel 301 of the lower fryer body 30 can also be cooled down well. The panel parts of both the upper fryer body 3 and the lower fryer body 30 can reduce the possibility of burns from touching the panel.
