Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of household appliances, in particular to an air fryer. Background Art
[0002] At present, in the relevant technology, air fryers are widely used for cooking food because of their low-fat advantage; however, when the air fryer is in use, fresh air from the outside will enter the cooking cavity through the air intake duct. However, since the outside air temperature is relatively low, after entering the cooking cavity, it will cause uneven temperature distribution in the cooking cavity. Utility Model Content
[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technologies.
[0004] To this end, a first aspect of the present invention provides an air fryer.
[0005] In view of this, the first aspect of the present invention provides an air fryer, comprising a main body, an air induction assembly, and a first heating element. The main body is provided with a cooking cavity and a heat dissipation cavity. The air induction assembly is disposed in the main body and is provided with a first air duct. The first end of the first air duct is connected to the cooking cavity, and the second end of the first air duct extends outward from the main body. The first air duct is connected to the heat dissipation cavity, so that air outside the air fryer and air inside the heat dissipation cavity can enter the cooking cavity through the first air duct.
[0006] In this technical solution, an air fryer includes a main body, an air induction assembly, and a first heating element. A cooking cavity and a heat dissipation cavity are provided within the main body to facilitate cooking of food through the cooking cavity. The air induction assembly is provided on the main body to facilitate the arrangement of the air induction assembly. The air induction assembly is provided with a first air duct, a first end of the first air duct being connected to the cooking cavity, a second end of the first air duct extending toward the exterior of the main body, and the first air duct being connected to the heat dissipation cavity, so that airflow within the heat dissipation cavity can enter the cooking cavity through the first air duct. Air outside the air fryer and air within the heat dissipation cavity can enter the cooking cavity through the first air duct, thereby allowing the air induction assembly to introduce outside air into the cooking cavity through the first air duct, so that the air fryer can cook food with the introduced air. Since there is hot air in the heat dissipation cavity, the hot air in the heat dissipation cavity enters the cooking cavity through the first air duct, thereby heating the fresh air entering the first air duct, reducing the impact of the fresh air on the temperature within the cooking cavity, and making the temperature within the cooking cavity more uniform.
[0007] In addition, the air fryer in the above technical solution provided by the present invention may also have the following additional technical features:
[0008] In some technical solutions of the present invention, optionally, the first heating component is arranged on a side of the first air duct close to the cooking cavity.
[0009] In this technical solution, the first heating component is disposed within the first air duct to achieve installation and fixation of the first heating component, so that the first heating component can heat the airflow within the first air duct. By disposing the first heating component within the first air duct, the present application allows air outside the air fryer to enter the cooking cavity through the first air duct, so that the air outside the air fryer is heated by the first heating component at the position of the first heating component to form hot air, which can then enter the cooking cavity, thereby heating the fresh air entering the first air duct, reducing the impact of the fresh air on the temperature within the cooking cavity, and making the temperature within the cooking cavity more uniform.
[0010] In some technical solutions of the present invention, optionally, the first heating component is arranged on a side of the first air duct close to the cooking cavity.
[0011] In this technical solution, the first heating component is arranged on a side of the first air duct close to the cooking cavity, so that the first heating component can heat the fresh air at a position close to the cooking cavity, so that the heated fresh air can quickly enter the cooking cavity to compensate for the temperature in the cooking cavity, thereby avoiding the temperature drop of the fresh air after heating due to the long circulation path.
[0012] In some technical solutions of the present invention, a third air duct is optionally provided on a side wall of the first air duct, and the air fryer further includes a first fan blade and a drive assembly. The first fan blade is disposed within the heat dissipation cavity; the drive assembly is connected to the first fan blade; and when the drive assembly rotates the first fan blade, airflow generated by the first fan blade can enter the first air duct through the third air duct, thereby driving outside air through the first air duct and into the cooking cavity.
[0013] In this technical solution, a third air duct is provided on the side wall of the first air duct to realize the arrangement of the third air duct. The first fan blade is provided in the heat dissipation cavity to realize the installation of the first fan blade. The drive assembly is connected to the first fan blade to realize the installation between the drive assembly and the first fan blade, so that the drive assembly drives the first fan blade to rotate. When the drive assembly drives the first fan blade to rotate, the airflow generated by the first fan blade can enter the first air duct through the third air duct, and then drive the outside air into the cooking cavity through the first air duct, thereby realizing that the air outside the air fryer can be introduced into the cooking cavity to cook the ingredients. The present application sets a third air duct on the first air duct. After the gas generated by the driving component driving the first fan blade to rotate enters the air duct through the third air duct, due to the fluid wall attachment effect, this starting airflow is adsorbed on the contour surface of the inner wall of the first air duct. Since the greater the gas flow rate, the lower the pressure, the starting airflow generates a low-pressure area in the center of the cavity of the first air duct, while the external ambient air is a normal pressure area. The pressure difference between the normal pressure area and the low-pressure area will introduce the external air into the first air duct, so that the external air enters the cooking cavity, thereby realizing the guidance of the external air. Compared with the method of setting a fan or air pump near the cooking cavity in the first air duct to extract the external air, the structure of the present application is simpler, and can also reduce the cost of setting up a fan or air pump. There is no need to drive the fan or air pump, thereby reducing the energy consumption of the air fryer.
[0014] In some technical solutions of the present invention, optionally, the air induction component is provided with a second air duct, one end of the second air duct is connected to the heat dissipation cavity, and the other end of the second air duct is connected to the first air duct through a third air duct.
[0015] In this technical solution, the air induced component is provided with a second air duct, one end of the second air duct is connected to the heat dissipation cavity, and the other end of the second air duct is connected to the first air duct through the third air duct, so as to realize the arrangement of the second air duct, so that the airflow generated when the first fan blade is working can flow to the third air duct through the second air duct, thereby allowing the airflow to flow into the first air duct through the third air duct, and then guide the outside air.

[0017] In this technical solution, one end of the second air duct connected to the heat dissipation cavity is the air inlet of the second air duct, so as to realize the arrangement of the air inlet, so that the first fan blade can blow the airflow to the air inlet of the second air duct when rotating, thereby providing airflow for the second air duct, allowing the airflow to flow into the first air duct, and then guiding the outside air.
[0018] In some technical solutions of the present invention, the air induction assembly optionally includes a first duct and a second duct. The first duct is located at the top of the cooking cavity and is provided with a first air duct. The first end of the second duct is connected to the first duct, the second end of the second duct extends toward the first fan blade, and the second duct is provided with a second air duct.
[0019] In this technical solution, the air induction component includes a first pipe and a second pipe. The first pipe is located at the top of the cooking cavity to realize the arrangement of the first pipe. The first pipe is provided with a first air duct so that the first air duct can pass the introduced airflow into the air fryer through the top of the cooking cavity. The first end of the second pipe is connected to the first pipe, and the second end of the second pipe extends toward the first fan blade to realize the arrangement of the second pipe. A second air duct is provided in the second pipe to realize the arrangement of the second air duct so that the airflow generated when the first fan blade is working can flow through the second air duct to the third air duct, so that the airflow flows through the third air duct into the first air duct, thereby guiding the air from the outside.

[0021] In this technical solution, the third air duct is arranged on the wall of the first pipe and around the first air duct, so that the airflow passing through the third air duct can enter the first air duct, and then drive the outside air into the cooking cavity through the gas in the first air duct.
[0022] In some technical solutions of the present invention, optionally, the first pipeline is provided with a pressurization chamber, which is arranged along the third air duct and communicated with the second air duct.
[0023] In this technical solution, the first duct is provided with a boost chamber, which is arranged along the third air duct and communicates with the second air duct. This arrangement allows the airflow from the second air duct to enter the first air duct through the boost chamber and the third air duct. By providing the boost chamber, the boost chamber can pressurize and accelerate the starting airflow entering the boost chamber, further reducing the pressure in the low-pressure area at the center of the first air duct cavity, thereby increasing the pressure difference between the low-pressure area and the air outside the air fryer, thereby ensuring that the air outside the air fryer can smoothly enter the cooking chamber.
[0024] In some technical solutions of the present invention, optionally, the boost chamber extends in a ring shape, and the minimum cross-sectional area of the third air duct is smaller than the cross-sectional area of the second air duct, so that the pressure of the gas entering the boost chamber is increased.

This arrangement of the third air duct allows the starting airflow in the boost chamber to enter the first air duct through the third air duct. The cross-sectional area of the third air duct decreases from the second end to the first end of the third air duct, so that the starting airflow gradually increases in velocity as it flows from the boost chamber to the first air duct in the third air duct. Once the starting airflow enters the first air duct through the third air duct, it further reduces the pressure in the low-pressure zone at the center of the cavity of the first air duct, thereby increasing the pressure difference between the low-pressure zone and the air outside the air fryer, thereby ensuring that the air outside the air fryer can smoothly enter the cooking chamber.

[0031] In this technical solution, the air fryer also includes an air scoop and a cover plate. The cover plate is connected to the main body and is located at the top of the cooking cavity to enable installation and fixation of the cover plate, so that the cover plate can shield the cooking cavity to facilitate protection of the cooking cavity. The air scoop is connected to the cover plate and is located on the side of the cover plate away from the cooking cavity to enable installation and fixation of the air scoop. An air scoop cavity is enclosed between the air scoop and the cover plate. The drive assembly is mounted on the air scoop, and the output shaft of the drive assembly extends into the air scoop cavity to enable installation of the drive assembly.

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0061] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0062] Refer to the following Figures 1 to 5 An air fryer 100 according to some embodiments of the present invention is described.
[0063] like Figure 1 and Figure 2 As shown, Figure 1 FIG1 shows one of the structural schematic diagrams of an air fryer 100 according to an embodiment of the present invention; Figure 2 A schematic structural diagram of an air induction assembly 106 according to an embodiment of the present invention is shown. In one embodiment of the present invention, an air fryer 100 is provided, comprising a body 102, an air induction assembly 106, and a first heating element 138. A cooking cavity 104 and a heat dissipation cavity 112 are provided within the body 102. The air induction assembly 106 is disposed within the body 102 and is provided with a first air duct 110. A first end of the first air duct 110 communicates with the cooking cavity 104, and a second end of the first air duct 110 extends toward the exterior of the body 102. The first air duct 110 communicates with the heat dissipation cavity 112. Air outside the air fryer 100 and air within the heat dissipation cavity 112 can enter the cooking cavity 104 through the first air duct 110.
[0064] In this embodiment, the air fryer 100 includes a body 102, an air induction assembly 106, and a first heating element 138. A cooking cavity 104 and a heat dissipation cavity 112 are provided within the body 102 to facilitate cooking of food in the cooking cavity 104. The air induction assembly 106 is disposed within the body 102 to facilitate the arrangement of the air induction assembly 106. The air induction assembly 106 is provided with a first air duct 110. A first end of the first air duct 110 communicates with the cooking cavity 104, and a second end of the first air duct 110 extends toward the exterior of the body 102. The first air duct 110 communicates with the heat dissipation cavity 112, allowing airflow within the heat dissipation cavity 112 to enter the cooking cavity 104 through the first air duct 110. Air outside the air fryer 100 and air within the heat dissipation cavity 112 can enter the cooking cavity 104 through the first air duct 110, allowing the air induction assembly 106 to introduce outside air into the cooking cavity 104 through the first air duct 110, so that the air fryer 100 can cook the food with the introduced air. Since there is hot air in the heat dissipation cavity 112, the hot air in the heat dissipation cavity 112 enters the cooking cavity 104 through the first air duct 110, thereby heating the fresh air entering the first air duct 110, reducing the impact of the fresh air on the temperature within the cooking cavity 104, and making the temperature within the cooking cavity 104 more uniform.
[0065] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0066] The first heating component 138 is disposed in the first air duct 110 .
[0067] In this embodiment, the first heating component 138 is disposed within the first air duct 110 to achieve installation and fixation of the first heating component 138 so that the first heating component 138 can heat the airflow within the first air duct 110. By disposing the first heating component 138 within the first air duct 110, the air outside the air fryer 100 can enter the cooking cavity 104 through the first air duct 110. As a result, the air outside the air fryer 100 is heated by the first heating component 138 at the location of the first heating component 138 to form hot air, which can then enter the cooking cavity 104. This heats the fresh air entering the first air duct 110, reduces the impact of the fresh air on the temperature within the cooking cavity 104, and makes the temperature within the cooking cavity 104 more uniform.
[0068] Specifically, by setting the first heating component 138 in the first air duct 110, the fresh air outside the air fryer 100 is heated to hot air before entering the cooking cavity 104, and the temperature of the food is compensated. Figure 3 As shown, Figure 3The figure shows the temperature of the bottom of the cooking cavity 104 without fresh air temperature compensation according to an embodiment of the present invention. Without fresh air temperature compensation, the fresh air entering the cooking cavity 104 affects the temperature inside the cooking cavity 104, forming a hot end area and a cold end area in the cooking cavity 104. Figure 4 As shown, Figure 4 A temperature diagram of the bottom of the cooking cavity 104 with fresh air temperature compensation according to an embodiment of the present invention is shown; by arranging a first heating component 138 in the first air duct 110, the hot air entering the cooking cavity 104 in the first air duct 110 can compensate for the fresh air temperature at the cold end of the cooking cavity 104, thereby increasing the temperature of the cold end area to improve the temperature uniformity in the cooking cavity 104.
[0069] Specifically, there are multiple first air ducts 110 and multiple first heating components 138. By setting multiple first air ducts 110 and multiple first heating components 138, the cooking cavity 104 can be temperature compensated. Taking the square barrel-shaped air fryer 100 as an example, under normal circumstances, there will be a corner cold end at the corner position of the cooking cavity 104. At this time, the first air duct 110 and the first heating component 138 are arranged above it. Before the outside air enters the cooking cavity 104, it will pass through the first heating component 138, and the passing fresh air will be heated to achieve the function of temperature compensation of the cold end of the cooking cavity 104. The cold end of the cooking cavity 104 can be effectively compensated for the temperature, and the uniformity of the cooking cavity 104 can be improved.
[0070] Specifically, in Figure 2 , arrows C and I represent the flow direction of the external air of the air fryer 100 in the first air duct 110 .
[0071] Specifically, in Figure 2 In the figure, the area pointed by arrow E is the low-pressure area, and the area pointed by arrow F is the normal-pressure area.
[0072] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0073] like Figure 1 As shown, the first heating component 138 is disposed on a side of the first air duct 110 close to the cooking cavity 104 .
[0074] In this embodiment, the first heating component 138 is arranged on a side of the first air duct 110 close to the cooking cavity 104, so that the first heating component 138 can heat the fresh air at a position close to the cooking cavity 104, so that the heated fresh air can quickly enter the cooking cavity 104 to compensate for the temperature in the cooking cavity 104, thereby avoiding the temperature drop of the fresh air due to the long circulation path after heating.
[0075] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0076] like Figure 1 and Figure 2 As shown, a third air duct 116 is provided on the sidewall of the first air duct 110. The air fryer 100 further includes a first fan blade 124 and a drive assembly 126. The first fan blade 124 is disposed within the heat dissipation cavity 112; the drive assembly 126 is connected to the first fan blade 124. When the drive assembly 126 drives the first fan blade 124 to rotate, the airflow generated by the first fan blade 124 can enter the first air duct 110 through the third air duct 116, thereby driving the outside air through the first air duct 110 and into the cooking cavity 104.
[0077] In this embodiment, a third air duct 116 is provided on the side wall of the first air duct 110 to realize the arrangement of the third air duct 116. The first fan blade 124 is provided in the heat dissipation cavity 112 to realize the installation of the first fan blade 124. The driving assembly 126 is connected to the first fan blade 124 to realize the installation between the driving assembly 126 and the first fan blade 124, so that the driving assembly 126 drives the first fan blade 124 to rotate. When the driving assembly 126 drives the first fan blade 124 to rotate, the airflow generated by the first fan blade 124 can enter the first air duct 110 through the third air duct 116, and then drive the outside air into the cooking cavity 104 through the first air duct 110, thereby realizing that the air outside the air fryer 100 can be introduced into the cooking cavity 104 to cook the ingredients. In the present application, a third air duct 116 is set on the first air duct 110. After the gas generated by the driving component 126 driving the first fan blade 124 to rotate enters the air duct through the third air duct 116, due to the fluid wall adhesion effect, this starting airflow is adsorbed on the contour surface of the inner wall of the first air duct 110. Since the greater the gas flow rate, the lower the pressure, the starting airflow generates a low-pressure area in the center of the cavity of the first air duct 110, while the external ambient air is a normal pressure area. The pressure difference between the normal pressure area and the low pressure area will introduce the external air into the first air duct 110, so that the external air enters the cooking cavity 104, thereby achieving the guidance of the external air. Compared with the method of setting a fan or air pump near the cooking cavity 104 in the first air duct 110 to extract the external air, the structure of the present application is simpler, and can also reduce the cost of setting up a fan or air pump. There is no need to drive the fan or air pump, thereby reducing the energy consumption of the air fryer 100.
[0078] Specifically, in Figure 2 , arrows D and H indicate the flow directions of the airflow generated by the first blades 124 .
[0079] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0080] The air induction assembly 106 is provided with a second air duct 122 . One end of the second air duct 122 is communicated with the heat dissipation cavity 112 , and the other end of the second air duct 122 is communicated with the first air duct 110 through the third air duct 116 .
[0081] In this embodiment, the air induced component 106 is provided with a second air duct 122, one end of the second air duct 122 is connected to the heat dissipation cavity 112, and the other end of the second air duct 122 is connected to the first air duct 110 through the third air duct 116, so as to realize the arrangement of the second air duct 122, so that the airflow generated when the first fan blade 124 is working can flow through the second air duct 122 to the third air duct 116, so that the airflow flows through the third air duct 116 to the first air duct 110, and then guides the external air.
[0082] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0083] like Figure 1 and Figure 2 As shown, one end of the second air duct 122 communicating with the heat dissipation cavity 112 is an air inlet 168 of the second air duct 122 , and at least a portion of the air inlet 168 faces the radial direction of the first fan blade 124 .
[0084] In this embodiment, one end of the second air duct 122 communicating with the heat dissipation cavity 112 is the air inlet 168 of the second air duct 122, and one end of the second air duct 122 communicating with the heat dissipation cavity 112 is the air inlet 168 of the second air duct 122, so as to realize the arrangement of the air inlet 168, so that the first fan blade 124 can blow the air flow toward the air inlet 168 of the second air duct 122 when rotating, thereby providing air flow for the second air duct 122, so that the air flow flows into the first air duct 110, and then guides the air from the outside.
[0085] Specifically, in Figure 1 , arrow J indicates the radial direction of the first blade 124 .
[0086] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0087] like Figure 1 and Figure 2 As shown, the air induction assembly 106 includes a first duct 108 and a second duct 120. The first duct 108 is located at the top of the cooking cavity 104 and is provided with a first air duct 110. The first end of the second duct 120 is connected to the first duct 108, and the second end of the second duct 120 extends toward the first fan blade 124. The second duct 120 is provided with a second air duct 122.
[0088] In this embodiment, the air induction assembly 106 includes a first duct 108 and a second duct 120. The first duct 108 is located at the top of the cooking cavity 104 to facilitate the arrangement of the first duct 108. The first duct 108 is provided with a first air duct 110, so that the first air duct 110 can pass the introduced airflow through the top of the cooking cavity 104 into the air fryer 100. The first end of the second duct 120 is connected to the first duct 108, and the second end of the second duct 120 extends toward the first fan blade 124 to facilitate the arrangement of the second duct 120. The second duct 120 is provided with a second air duct 122 to facilitate the arrangement of the second air duct 122. The airflow generated by the operation of the first fan blade 124 can flow through the second air duct 122 to the third air duct 116, thereby allowing the airflow to flow through the third air duct 116 into the first air duct 110, thereby guiding the external air.
[0089] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0090] like Figure 1 and Figure 2 As shown, the third air duct 116 is provided on the wall of the first duct 108 and is arranged around the first air duct 110;
[0091] In this embodiment, the third air duct 116 is arranged on the wall of the first pipe 108 and is arranged around the first air duct 110 so that the airflow passing through the third air duct 116 can enter the first air duct 110, thereby driving the external air into the cooking cavity 104 through the gas in the first air duct 110.
[0092] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0093] like Figure 1 and Figure 2 As shown, the first duct 108 is provided with a pressurizing chamber 114 , which is arranged along the third air duct 116 and communicates with the second air duct 122 .
[0094] In this embodiment, the first duct 108 is provided with a pressurizing chamber 114, which is arranged along the third air duct 116 and communicates with the second air duct 122. This arrangement of the pressurizing chamber 114 allows the airflow from the second air duct 122 to enter the first air duct 110 through the pressurizing chamber and the third air duct 116. The provision of the pressurizing chamber 114 allows the pressurizing chamber 114 to pressurize and accelerate the starting airflow entering the pressurizing chamber 114, further reducing the pressure in the low-pressure area at the center of the first air duct 110, thereby increasing the pressure difference between the low-pressure area and the air outside the air fryer 100, thereby ensuring that the air outside the air fryer 100 can smoothly enter the cooking chamber 104.
[0095] Furthermore, the second air duct 122 is a fresh air starting duct, and the first fan blade 124 is a heat dissipation air moving device. The fresh air starting duct connects the fresh air duct and the heat dissipation air moving device. The heat dissipation air moving device drives the air into the fresh air starting duct, and after passing through the boost chamber 114 of the fresh air starting duct, it is blown into the fresh air duct through the third air duct 116 of the fresh air duct. After the heat dissipation air passes through the third air duct 116 at high speed, due to the fluid wall attachment effect, this starting airflow is adsorbed on the contour surface of the inner wall of the fresh air duct. The greater the gas flow rate, the lower the pressure. The starting airflow generates a low-pressure area in the center of the fresh air channel cavity, and the external ambient air is a normal pressure area. The pressure difference will press the external air into the fresh air duct, and then enter the cooking cavity 104.
[0096] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0097] The boost chamber 114 extends in an annular shape, and the minimum cross-sectional area of the third air duct 116 is smaller than the cross-sectional area of the second air duct 122 , so that the pressure of the gas entering the boost chamber 114 is increased.
[0098] In this embodiment, the boost chamber 114 extends in a ring shape to realize the arrangement of the boost chamber 114. The minimum cross-sectional area of the cross section of the third air duct 116 is smaller than the cross-sectional area of the cross section of the second air duct 122, so that the pressure of the gas entering the boost chamber 114 is increased, so that the boost chamber 114 can pressurize and speed up the starting airflow entering the boost chamber 114.
[0099] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0100] like Figure 2As shown, the first end of the third air duct 116 is connected to the first air duct 110 , the second end of the third air duct 116 is connected to the boost chamber 114 , and the cross-sectional area of the third air duct 116 decreases from the second end to the first end of the third air duct 116 .
[0101] In this embodiment, a first end of the third air duct 116 is connected to the first air duct 110, and a second end of the third air duct 116 is connected to the pressurization chamber 114. This arrangement of the third air duct 116 allows the starting airflow within the pressurization chamber 114 to enter the first air duct 110 through the third air duct 116. The cross-sectional area of the third air duct 116 decreases from the second end to the first end of the third air duct 116. This causes the starting airflow to gradually increase in velocity as it flows from the pressurization chamber 114 to the first air duct 110 through the third air duct 116. Once the starting airflow enters the first air duct 110 through the third air duct 116, it further reduces the pressure in the low-pressure region at the center of the first air duct 110, thereby increasing the pressure difference between the low-pressure region and the air outside the air fryer 100. This ensures that air outside the air fryer 100 can smoothly enter the cooking chamber 104.
[0102] Specifically, the third air duct 116 is a volute.
[0103] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0104] like Figure 1 and Figure 2 As shown, the third air duct 116 is arranged obliquely relative to the axis of the first air duct 110 , and the third air duct 116 extends from the second end of the third air duct 116 to the first end of the third air duct 116 toward the cooking cavity 104 .
[0105] In this embodiment, the third air duct 116 is arranged obliquely relative to the axis of the first air duct 110, and the third air duct 116 extends from the second end of the third air duct 116 to the first end of the third air duct 116 toward the cooking cavity 104, so as to realize the arrangement of the third air duct 116, so that after the starting airflow in the third air duct 116 flows into the first air duct 110 through the third air duct 116, the starting airflow can flow in the first air duct 110 toward the cooking cavity 104, thereby guiding the flow of the starting airflow, improving the wall attachment effect of the starting airflow in the first air duct 110, and then increasing the volume of the low-pressure area, thereby increasing the air intake of the external air of the air fryer 100.
[0106] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0107] like Figure 1 As shown, the air fryer 100 further includes an air scoop 132 and a cover plate 130. The cover plate 130 is connected to the body 102 and is located at the top of the cooking cavity 104. This allows the cover plate 130 to be installed and fixed, so that the cover plate 130 can shield the cooking cavity 104 to protect the cooking cavity 104. The air scoop 132 is connected to the cover plate 130 and is located on the side of the cover plate 130 away from the cooking cavity 104. An air scoop cavity 134 is defined between the air scoop 132 and the cover plate 130. The drive assembly 126 is mounted on the air scoop 132, and the output shaft 128 of the drive assembly 126 extends into the air scoop cavity 134. The first fan blade 124 is located in the air scoop cavity 134 and is connected to the output shaft 128 of the drive assembly 126. The second end of the second duct 120 is connected to the air scoop 132, and the second air duct 122 is in communication with the air scoop cavity 134.
[0108] In this embodiment, the air fryer 100 further includes an air scoop 132, which is connected to the cover plate 130 and is located on a side of the cover plate 130 away from the cooking chamber 104, thereby facilitating the installation and fixation of the air scoop 132. An air scoop cavity 134 is defined between the air scoop 132 and the cover plate 130. The drive assembly 126 is mounted on the air scoop 132, and the output shaft 128 of the drive assembly 126 extends into the air scoop cavity 134, thereby facilitating the installation of the drive assembly 126. The first fan blade 124 is located within the air scoop cavity 134 and is connected to the output shaft 128 of the drive assembly 126, allowing the first fan blade 124 to rotate within the air scoop cavity 134. The second end of the second duct 120 is connected to the air scoop 132, thereby facilitating the installation and fixation of the second duct 120. The second air duct 122 is connected to the air guide cavity 134, so that the starting airflow generated by the first fan blade 124 can enter the second air duct 122 through the air guide cavity 134. By providing the air guide cover 132, the air guide cover 132 can guide the airflow, thereby guiding the airflow generated by the first fan blade 124 to the second air duct 122.
[0109] Specifically, the driving assembly 126 and the first fan blade 124 are disposed on a side of the cover 130 away from the cooking cavity 104 to achieve installation and fixation of the driving assembly 126 and the first fan blade 124 .
[0110] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0111] like Figure 1As shown, the output shaft 128 of the drive assembly 126 extends to the side of the cover plate 130 near the cooking cavity 104. The air fryer 100 also includes a second fan blade 136 and a second heating element 140. The second fan blade 136 is connected to the output shaft 128 of the drive assembly 126 and is located on the side of the cover plate 130 near the cooking cavity 104. The second heating element 140 is mounted on the cover plate 130 and is arranged along the axial direction of the drive assembly 126 together with the second fan blade 136.
[0112] In this embodiment, the output shaft 128 of the drive assembly 126 extends to the side of the cover plate 130 near the cooking chamber 104 to facilitate the arrangement of the output shaft 128 of the drive assembly 126. The air fryer 100 also includes a second fan blade 136 and a second heating element 140. The second fan blade 136 is connected to the output shaft 128 of the drive assembly 126 and is located on the side of the cover plate 130 near the cooking chamber 104 to facilitate the installation of the second fan blade 136. The drive assembly 126 can drive the second fan blade 136 to rotate, so that the first fan blade 124 and the second fan blade 136 can share the same drive assembly 126. The second heating element 140 is mounted on the cover plate 130 and is arranged along the axial direction of the drive assembly 126 with the second fan blade 136 to facilitate the installation and fixation of the second heating element 140. By providing the second heating component 140 and the second fan blade 136, the second heating component 140 can heat the air. When the second fan blade 136 rotates, the hot air generated by the second heating component 140 can be quickly circulated into the cooking cavity 104, so that the temperature in the cooking cavity 104 can be evenly distributed, ensuring that the food in the cooking cavity 104 is heated evenly. Moreover, when the second fan blade 136 rotates, the hot air can also flow quickly and evenly around the food, so that the food quickly reaches a high temperature state, thereby achieving cooking of the food.
[0113] Specifically, in Figure 1 , arrow B indicates the axial direction of the drive assembly 126 .
[0114] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0115] like Figure 3 As shown, the cooking cavity 104 includes a first area 170 and a second area 172 . When the air fryer cooks food, the temperature of the first area 170 is lower than the temperature of the second area 172 . The first end of the first air duct 110 faces the first area 170 .
[0116] In this embodiment, the cooking cavity 104 includes a first area 170 and a second area 172. When the air fryer cooks food, the temperature of the first area 170 is lower than that of the second area 172; the first end of the first air duct 110 faces the first area 170, so that the hot air entering the cooking cavity 104 from the first air duct 110 can compensate for the fresh air temperature of the cold end in the cooking cavity 104, thereby increasing the temperature of the cold end area to improve the temperature uniformity in the cooking cavity 104.
[0117] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0118] There are multiple first areas 170 and multiple second areas 172, and the multiple first areas 170 and multiple second areas 172 are arranged alternately; there are multiple air induced components 106, and the first air ducts 110 of the multiple air induced components 106 are arranged corresponding to the multiple first areas 170 respectively.
[0119] In this embodiment, there are multiple first regions 170 and multiple second regions 172, and the multiple first regions 170 and the multiple second regions 172 are arranged alternately to achieve a configuration of multiple first regions 170 and multiple second regions 172. There are multiple air induction assemblies 106, and the first air ducts 110 of the multiple air induction assemblies 106 are arranged corresponding to the multiple first regions 170, respectively, to achieve an arrangement of the air induction assemblies 106 such that the multiple air induction assemblies 106 can simultaneously provide fresh air temperature compensation to the multiple first regions 170, thereby increasing the temperature of the cold end region and improving temperature uniformity within the cooking cavity 104.
[0120] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0121] like Figure 1 and Figure 5 As shown, Figure 5 for Figure 1 The air fryer 100 is a partial schematic diagram of a portion A according to an embodiment of the present invention. The air fryer 100 further includes a fan assembly 146 , which is disposed at the second end of the first air duct 110 and exposed to the body 102 . The fan assembly 146 includes third blades 148 . The flow of gas within the first air duct 110 can drive the third blades 148 to rotate.
[0122] In this embodiment, the air fryer 100 further includes a fan assembly 146. The fan assembly 146 is disposed at the second end of the first air duct 110 and is exposed to the body 102. The fan assembly 146 includes a third blade 148. The gas flow in the first air duct 110 can drive the third blade 148 to rotate. The fan assembly 146 is disposed at the second end of the first air duct 110 and is exposed to the body 102. The fan assembly 146 being exposed to the body 102 can visualize the internal operation of the fan assembly 146. The user can observe the rotation of the third blade 148 through the exposed fan assembly 146, thereby judging the air intake status of the cooking cavity 104. The exposed fan assembly 146 is provided with a light-transmissive cover 160, which allows the user to intuitively observe the rotation of the third blade 148 inside, thereby improving the cooking effect of the food and enhancing the user experience.
[0123] Furthermore, the fan assembly 146 may be exposed outside the body 102 in a specific manner: the third fan blade 148 may be placed outside the body 102, the third fan blade 148 may be disposed inside the body 102, or a portion of the third fan blade 148 may be disposed outside the body 102 and another portion of the third fan blade 148 may be disposed inside the body 102. The placement of the third fan blade 148 only needs to facilitate the user's observation of the rotation of the third fan blade 148. The fan portion of the third fan blade 148 may be selected in a color with high color differentiation, making it easier for the user to observe the rotation of the third fan blade 148 and providing better feedback to the user on the operating status of the air fryer 100.
[0124] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0125] like Figure 5 As shown, fan assembly 146 further includes a base 150 and a stop assembly 152. Stop assembly 152 is disposed on base 150; third blade 148 is disposed on the upper side of stop assembly 152 and connected to stop assembly 152. Stop assembly 152 restricts movement of third blade 148 toward stop assembly 152, and third blade 148 is capable of rotating relative to stop assembly 152.
[0126] In this embodiment, the fan assembly 146 also includes a base 150 and a limiting assembly 152. The limiting assembly 152 is arranged on the base 150, and the base 150 can provide support for the limiting assembly 152. At the same time, the provision of the base 150 can facilitate the installation of the third fan blade 148 and the limiting assembly 152. The third fan blade 148 is arranged on the upper side of the limiting assembly 152 and is connected to the limiting assembly 152. The limiting assembly 152 limits the movement of the third fan blade 148 in the direction of the limiting assembly 152, and the third fan blade 148 can rotate relative to the limiting assembly 152. The third fan blade 148 is arranged on the upper side of the limiting assembly 152 and is connected to the limiting assembly 152. The limiting assembly 152 limits the movement of the third fan blade 148 in the direction of the limiting assembly 152, and the third fan blade 148 can rotate relative to the limiting assembly 152. By setting the limiting component 152 to limit the third fan blade 148, the third fan blade 148 can be prevented from falling off. At the same time, setting the limiting component 152 can reduce the contact area of the third fan blade 148 during rotation, thereby reducing friction. When the gas flows through the third fan blade 148, the rotation effect of the third fan blade 148 can be improved, which makes it easier for the user to observe the rotation of the third fan blade 148 and enhance the user experience. At the same time, reducing friction can reduce the wear of the third fan blade 148, thereby extending the product life.
[0127] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0128] like Figure 5 As shown, the limiting assembly 152 includes a first matching portion 154 and a first limiting portion 156. The first limiting portion 156 matches the first matching portion 154; one of the base 150 and the third fan blade 148 is connected to the first matching portion 154; and the other of the base 150 and the third fan blade 148 is connected to the first limiting portion 156.
[0129] In this embodiment, the limiting assembly 152 includes a first matching portion 154 and a first limiting portion 156.

The installation cavity 166 can provide space for the installation of the third fan blade 148, and at the same time facilitate the production and installation of the third fan blade 148. The cover body 160 can protect the third fan blade 148 in the installation cavity 166.
[0138] Specifically, the cover 160 and the base 150 are connected by threads to improve the installation stability between the cover 160 and the base 150 .
[0139] Specifically, the cover 160 and the base 150 are connected by a buckling method to improve the installation stability between the cover 160 and the base 150 .
[0140] Specifically, when the cover plate 130 and the base body 150 clamp and limit the third fan blade 148 , the third fan blade 148 can rotate relative to the limiting assembly 152 .
[0141] This embodiment provides an air fryer 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.
[0142] like Figure 5 As shown, the fan assembly 146 further includes a second mating portion 162 and a second limiting portion 164. The second limiting portion 164 is mated with the second mating portion 162; one of the cover 160 and the third fan blade 148 is connected to the second mating portion 162; and the other of the cover 160 and the third fan blade 148 is connected to the second limiting portion 164.
[0143] In this embodiment, fan assembly 146 further includes a second mating portion 162 and a second limiting portion 164. Second limiting portion 164 mates with second mating portion 162 to facilitate installation between second limiting portion 164 and second mating portion 162.

By setting the second matching portion 162 and the second limiting portion 164 to limit the position of the third fan blade 148, the stability of the third fan blade 148 can be improved to prevent the third fan blade 148 from falling off. At the same time, the second limiting portion 164 can be set to contact the third fan blade 148, while the second matching portion 162 is not in contact with the third fan blade 148. At the same time, the second matching portion 162 can be set to contact the third fan blade 148, while the second limiting portion 164 is not in contact with the third fan blade 148, thereby reducing the contact area between the third fan blade 148 and the second limiting portion 164 and the second matching portion 162 when rotating, thereby reducing friction resistance.
