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 because of their low-fat advantage in cooking food. However, when the air fryer is in use, external air needs to be introduced into the cooking cavity through an air inlet channel so that the air fryer can cook the food. Usually, a fan or air pump is set in the air inlet channel to draw external air into the cooking cavity. However, the method of setting a fan or air pump in the air inlet channel makes the structure of the air fryer complicated. 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, a first fan blade, and a drive assembly. The main body is provided with a cooking cavity and a heat dissipation cavity; the air induction assembly is disposed on the main body, and 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; the first fan blade is disposed within the heat dissipation cavity; and the drive assembly is connected to the first fan blade. 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, thereby driving outside air into the cooking cavity through the first air duct.

[0006] In this technical solution, an air fryer includes a main body, an air induction assembly, a first fan blade, and a drive assembly. A cooking cavity and a heat dissipation cavity are provided within the main body to facilitate cooking of food in the cooking cavity. The air induction assembly is disposed within the main body to facilitate placement of the air induction assembly. The air induction assembly is provided with a first air duct, a first end of the first air duct communicating with the cooking cavity, and a second end of the first air duct extending toward the exterior of the main body. This allows the air induction assembly to draw outside air into the cooking cavity through the first air duct, allowing the air in the air fryer to cook food using the introduced air. The first air duct communicates with the heat dissipation cavity to facilitate placement of the first air duct. The first fan blade is disposed within the heat dissipation cavity to facilitate mounting of the first fan blade. The drive assembly is connected to the first fan blade to facilitate mounting therebetween, allowing the drive assembly to drive the first fan blade to rotate. When the drive assembly drives the first fan blade to rotate, air generated by the first fan blade can enter the first air duct, thereby driving outside air through the first air duct into the cooking cavity, thereby allowing air outside the air fryer to be drawn into the cooking cavity to cook food. In the present application, the first air duct is connected with the heat dissipation cavity, and the gas generated by the driving component driving the first fan blade to rotate enters the first air duct from the heat dissipation cavity. 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.

[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 air fryer further includes a humidifying component, at least a portion of which is disposed in the first air duct or communicated with the first air duct.

[0009] In this technical solution, the air fryer further includes a humidifying assembly, at least a portion of which is disposed within or communicates with the first air duct, thereby enabling installation and fixation of the humidifying assembly. By disposing the humidifying assembly within the first air duct or communicating with the first air duct, the humidifying assembly can humidify the air passing through the first air duct during the cooking process, allowing the humidified air to diffuse after entering the cooking chamber, providing an appropriate amount of moisture to the food, preventing the food from being carried away too much moisture by the air during cooking, thereby preventing the food from having a dry taste, and improving the edible quality of the food.

[0010] 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, and the second end of the second duct extends toward the air guide cavity where the first fan blade is located. The second duct is provided with a second air duct that is connected to the first air duct.

[0011] 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 to the air guide cavity where the first fan blade is located to realize the arrangement of the second pipe. A second air duct is provided in the second pipe, and the second air duct is connected to the first air duct to realize the arrangement of the second air duct, so that the airflow generated when the first fan blade is working can flow into the first air duct through the second air duct, thereby guiding the air from the outside.

[0012] In some technical solutions of the present invention, optionally, one end of the second air duct communicating with the heat dissipation cavity is an air inlet of the second air duct, and at least part of the air inlet faces the radial direction of the first fan blade.

[0013] 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.

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.

[0018] In some technical solutions of the present invention, optionally, the first end of the third air duct is connected to the first air duct, the second end of the third air duct is connected to the boost chamber, and the cross-sectional area of ​​the third air duct decreases from the second end of the third air duct to the first end of the third air duct.

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. As the starting airflow flows from the boost chamber to the first air duct in the third air duct, the flow rate of the starting airflow gradually increases. When the starting airflow enters the first air duct, the pressure in the low-pressure area at the center of the cavity of the first air duct is further reduced, 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 air fryer further includes a cover plate, which is connected to the body and is located at the top of the cooking cavity; the drive assembly and the first fan blade are arranged on a side of the cover plate away from the cooking cavity.

The heating component is installed on the cover plate and is arranged axially with the second fan blade along the drive assembly to achieve the installation and fixation of the heating component. By providing the heating component and the second fan blade, the heating component can heat the air. When the second fan blade rotates, the hot air generated by the heating component can be quickly circulated into the cooking chamber, so that the temperature in the cooking chamber can be evenly distributed, ensuring that the food in the cooking chamber is heated evenly, and when the second fan blade 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.

DETAILED DESCRIPTION

[0055] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0056] 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.

[0057] Refer to the following Figures 1 to 5 An air fryer 100 according to some embodiments of the present invention is described.

[0058] 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 2The present invention provides an air fryer 100, comprising a main body 102, an air induced component 106, a first fan blade 124, and a drive component 126. The main body 102 is provided with a cooking cavity 104 and a heat dissipation cavity 112. The air induced component 106 is provided on the main body 102 and is provided with a first air duct 110. The first end of the first air duct 110 is connected to the cooking cavity 104, and the second end of the first air duct 110 extends to the outside of the main body 102, and the first air duct 110 is connected to the heat dissipation cavity 112. The first fan blade 124 is provided in the main body 102. The drive component 126 is connected to the first fan blade 124. When the drive component 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, thereby driving the outside air into the cooking cavity 104 through the first air duct 110.

[0059] In this embodiment, the air fryer 100 includes a body 102, an air induction assembly 106, a first fan blade 124, and a drive assembly 126. The body 102 is provided with a cooking cavity 104 and a heat dissipation cavity 112, so that food can be cooked through the cooking cavity 104. The air induction assembly 106 is disposed within the body 102 to facilitate the placement 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. This allows the air induction assembly 106 to draw outside air into the cooking cavity 104 through the first air duct 110, so that the air induction assembly 106 can cook food using the introduced air. The first air duct 110 communicates with the heat dissipation cavity 112 to facilitate the placement of the first air duct 110. The first fan blade 124 is disposed within the heat dissipation cavity 112 to facilitate the installation of the first fan blade 124. The drive assembly 126 is connected to the first fan blade 124 to achieve the installation between the drive assembly 126 and the first fan blade 124, so that the drive assembly 126 drives the first fan blade 124 to rotate. 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, and then drive the outside air into the cooking cavity 104 through the first air duct 110, so that the air outside the air fryer 100 can be introduced into the cooking cavity 104 to cook the food. In the present application, the first air duct 110 is connected to the heat dissipation cavity 112, and the driving component 126 drives the first fan blade 124 to rotate to generate gas. After the gas enters the first air duct 110 from the heat dissipation cavity 112, 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 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 in the first air duct 110 near the cooking cavity 104 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.

[0060] Specifically, the first duct 108 is a fresh air introduction channel, so that external air can be introduced into the cooking cavity 104.

[0061] Specifically, in Figure 2 In the figure, arrows C and I represent the flow direction of the external air of the air fryer 100 in the first air duct 110, and arrows D and H represent the flow direction of the airflow generated by the first fan blade 124.

[0062] 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.

[0063] 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.

[0064] like Figure 3 and Figure 4 As shown, Figure 3 FIG2 shows a second structural diagram of an air fryer 100 according to an embodiment of the present invention; Figure 4 The second structural schematic diagram of the air induction component 106 according to an embodiment of the present invention is shown; the air fryer 100 also includes a humidifying component 140, at least part of the humidifying component 140 is arranged in the first air duct 110 or communicated with the first air duct 110.

[0065] In this embodiment, the air fryer 100 further includes a humidifying assembly 140, at least a portion of which is disposed within or in communication with the first air duct 110, thereby enabling installation and fixation of the humidifying assembly 140. By disposing the humidifying assembly 140 within the first air duct 110 or by communicating with the first air duct 110, the humidifying assembly 140 can humidify the air passing through the first air duct 110 during the cooking process. This allows for water humidification at the outset of cooking, eliminating the need for heated liquid water during the cooking process. Furthermore, the Venturi effect draws in water vapor, preventing water mist molecules from being directly injected into the cooking chamber 104. Air-driven inlet distribution is more uniform than with fixed nozzles, providing an appropriate amount of moisture to the food, preventing excessive moisture from being carried away by the air during cooking, thereby preventing the food from having a dry taste and improving the quality of the food.

[0066] Specifically, the Venturi effect describes the increase in flow velocity when a confined fluid passes through a narrowing flow path.

[0067] Specifically, in Figure 4 In the figure, arrows C and I represent the flow direction of the external air of the air fryer 100 in the first air duct 110, and arrows D and H represent the flow direction of the airflow generated by the first fan blade 124.

[0068] Specifically, in Figure 4 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.

[0069] 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.

[0070] like Figure 2As 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 to the air guide cavity 134 where the first fan blade 124 is located. The second duct 120 is provided with a second air duct 122, which is connected to the first air duct 110.

[0071] 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 to the air guide cavity 134 where the first fan blades 124 are located to facilitate the arrangement of the second duct 120. The second duct 120 is provided with a second air duct 122, which is connected to the first air duct 110 to facilitate the arrangement of the second air duct 122. The airflow generated by the first fan blades 124 when in operation can flow through the second air duct 122 into the first air duct 110, thereby guiding the external air.

[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 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 .

[0074] 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.

[0075] Specifically, in Figure 1 , arrow J indicates the radial direction of the first blade 124 .

[0076] 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.

[0077] like Figure 1 and Figure 2 As shown, the first duct 108 is provided with a third air duct 116 , and the third air duct 116 is arranged around the first air duct 110 .

[0078] In this embodiment, the first pipe 108 is provided with a third air duct 116, and the third air duct 116 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, and then drive the external air into the cooking cavity 104 through the gas in the first air duct 110.

[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] 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 .

[0081] 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.

[0082] 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 opening of the third air duct 116 of the fresh air duct. After the heat dissipation air passes through the opening of 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.

[0083] 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.

[0084] like Figure 1 and Figure 2 As 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 of the third air duct 116 to the first end of the third air duct 116.

[0085] 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 allows the startup 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 startup 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 startup airflow enters the first air duct 110, 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 the air outside the air fryer 100 can smoothly enter the cooking chamber 104.

[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 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 .

[0088] 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.

[0089] Specifically, the third air duct 116 is a volute.

[0090] 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.

[0091] like Figure 1 and Figure 2 As shown, the cross-sectional area of ​​the first air duct 110 decreases from the end away from the cooking cavity 104 to the third air duct 116 ; the cross-sectional area of ​​the first air duct 110 decreases from the end close to the cooking cavity 104 to the third air duct 116 .

[0092] In this embodiment, the cross-sectional area of ​​the first air duct 110 decreases from the end away from the cooking cavity 104 to the third air duct 116; the cross-sectional area of ​​the first air duct 110 decreases from the end close to the cooking cavity 104 to the third air duct 116, so that the cross-sectional area of ​​the first air duct 110 at the third air duct 116 is the smallest, thereby accelerating the flow rate of the gas at the third air duct 116, and then increasing the pressure difference between the low-pressure area and the outside of the air fryer 100, to ensure that the gas outside the air fryer 100 continuously flows into the cooking cavity 104 through the first air duct 110.

[0093] 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.

[0094] like Figure 1 As shown, the air fryer 100 further includes a cover 130 , which is connected to the body 102 and is located at the top of the cooking cavity 104 ; the drive assembly 126 and the first fan blade 124 are arranged on a side of the cover 130 away from the cooking cavity 104 .

[0095] In this embodiment, the air fryer 100 further includes a cover 130. The cover 130 is connected to the body 102 and is located at the top of the cooking cavity 104. This allows the cover 130 to be installed and secured, shielding the cooking cavity 104 and protecting it. The drive assembly 126 and the first fan blade 124 are disposed on a side of the cover 130 away from the cooking cavity 104, allowing the drive assembly 126 and the first fan blade 124 to be installed and secured.

[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] like Figure 1As shown, the air fryer 100 also includes an air guide cover 132, which is connected to the cover 130 and is located on the side of the cover 130 away from the cooking cavity 104, and an air guide cavity 134 is enclosed between the air guide cover 132 and the cover 130; the driving component 126 is installed on the air guide cover 132, and the output shaft 128 of the driving component 126 extends into the air guide cavity 134; the first fan blade 124 is located in the air guide cavity 134 and is connected to the output shaft 128 of the driving component 126; the second end of the second pipe 120 is connected to the air guide cover 132, and the second air duct 122 is connected to the air guide cavity 134.

[0098] 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.

[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 1 As shown, the output shaft 128 of the drive assembly 126 extends to the side of the cover 130 near the cooking cavity 104. The air fryer 100 also includes a second fan blade 136 and a heating element 138. 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 130 near the cooking cavity 104. The heating element 138 is mounted on the cover 130 and is arranged along the axial direction of the drive assembly 126 together with the second fan blade 136.

[0101] 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 further includes a second fan blade 136 and a heating element 138. 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 heating element 138 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 heating element 138. By providing the heating component 138 and the second fan blade 136, the heating component 138 can heat the air. When the second fan blade 136 rotates, the hot air generated by the heating component 138 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.

[0102] Specifically, in Figure 1 , arrow B indicates the axial direction of the drive assembly 126 .

[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 3 and Figure 4 As shown, the humidifying assembly 140 includes a liquid storage component 142 and a humidifying component 144. The liquid storage component 142 is disposed in the body 102; the first end of the humidifying component 144 is disposed in the first air duct 110 or communicates with the first air duct 110, and the second end of the humidifying component 144 extends into the liquid storage component 142.

[0105] In this embodiment, the humidifying assembly 140 includes a liquid storage component 142 and a humidifying component 144. The liquid storage component 142 is disposed within the main body 102 to facilitate installation and fixation. A first end of the humidifying component 144 is disposed within or communicates with the first air duct 110, and a second end of the humidifying component 144 extends into the liquid storage component 142 to facilitate installation and fixation of the humidifying component 144. This allows the liquid in the liquid storage component 142 to humidify the airflow within the first air duct 110 through the humidifying component 144. Furthermore, the provision of the liquid storage component 142 allows the liquid storage component 142 to continuously humidify the airflow within the first air duct 110 during operation of the air fryer 100.

[0106] Specifically, in Figure 3 In FIG. 1 , arrow K indicates the flow direction of the liquid in the liquid storage part 142 in the humidifying part 144 .

[0107] 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.

[0108] The humidifying member 144 is a capillary tube, a sponge or a textile.

[0109] In this embodiment, the humidifying component 144 is a capillary tube, a sponge or a textile. The capillary tube, the sponge or the textile has good water absorption and moisturizing capabilities, so that it can absorb liquid from the liquid storage component 142 to humidify the airflow in the first air duct 110. The structure of the capillary tube, the sponge or the textile is simple and easy to install, disassemble and maintain.

[0110] Specifically, the humidifying component 144 is a capillary tube.

[0111] Specifically, the humidifying member 144 is a sponge.

[0112] Specifically, the humidifying component 144 is textile.

[0113] Specifically, the liquid is water, the humidifying component 144 is a water supply structure, the liquid storage component 142 is a water storage structure, the water supply structure is a capillary tube, a sponge or a textile, and the water storage structure is connected to the first air duct 110 through the water supply structure. Water moves to the first air duct 110 through the capillary tube, sponge or textile. The outside air is humidified when passing through the capillary tube, sponge or textile, and the humidified air enters the cooking cavity 104 to heat the food.

[0114] Specifically, the liquid storage component 142 is a water tank.

[0115] Specifically, the first fan blade 124 is a heat dissipation fan blade, and the airflow generated by the first fan blade 124 passes through the second air duct 122 and is ejected from the third air duct 116 at high speed. Due to the wall adhesion effect of the fluid, the ejected gas is adsorbed on the inner wall contour surface of the first air duct 110. 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, and the external ambient air is a normal pressure area. The pressure difference will press the external air into the first air duct 110, and then into the cooking cavity 104; before the air enters the cooking cavity 104, it will pass through the humidifying component 144, and the moisture in the humidifying component 144 is taken away by the air, and the humidified air enters the cooking cavity 104 to achieve humidification of the food.

[0116] 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.

[0117] like Figure 1 and Figure 5 As shown, Figure 5 for Figure 1 The air fryer 100 is a partial schematic diagram at point A according to an embodiment of the present invention; the air fryer 100 also includes a fan assembly 146, which is arranged at the second end of the first air duct 110 and exposed to the body 102. The fan assembly 146 includes a third fan blade 148, and the gas flow in the first air duct 110 can drive the third fan blade 148 to rotate.

[0118] 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.

[0119] 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.

[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 5As 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] In this embodiment, the limiting assembly 152 includes a first matching portion 154 and a first limiting portion 156. The first limiting portion 156 cooperates with the first matching portion 154 to achieve installation between the first limiting portion 156 and the first matching portion 154. One of the base 150 and the third fan blade 148 is connected to the first matching portion 154. By setting the first matching portion 154 and the first limiting portion 156 to limit the position of the third fan blade 148, the stability of the third fan blade 148 can be improved and the third fan blade 148 can be prevented from falling off. At the same time, the first limiting portion 156 can be set to contact the third fan blade 148, while the first matching portion 154 and the third fan blade 148 do not contact. At the same time, the first matching portion 154 can be set to contact the third fan blade 148, while the first limiting portion 156 and the third fan blade 148 do not contact. In addition, the first matching portion 154 can be set to contact the third fan blade 148, while the first limiting portion 156 and the third fan blade 148 do not contact. In this way, the contact area between the third fan blade 148 and the first limiting portion 156 and the first matching portion 154 when the third fan blade 148 rotates is reduced, thereby reducing friction resistance.

[0126] 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.

[0127] like Figure 5 As shown, a first gap 158 is defined between the first matching portion 154 and the first limiting portion 156 , and the first gap 158 is arranged around the circumference of the first matching portion 154 .

[0128] In this embodiment, there is a first gap 158 between the first matching portion 154 and the first limiting portion 156, and the first gap 158 is arranged circumferentially around the first matching portion 154, reducing the friction between the circumferential side wall of the first matching portion 154 and the first limiting portion 156, thereby reducing the resistance of the third fan blade 148 during rotation and improving the smoothness of the rotation of the third fan blade 148.

[0129] Furthermore, in the axial direction of the first matching portion 154 , the first matching portion 154 contacts the first limiting portion 156 .

[0130] Specifically, in Figure 5 , arrow G indicates the circumferential direction of the first mating portion 154 .

[0131] 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.

[0132] like Figure 5 As shown, the fan assembly 146 further includes a cover 160 . The cover 160 is disposed on the base 150 . The cover 160 and the base 150 define a mounting cavity 166 .

[0133] In this embodiment, the fan assembly 146 also includes a cover body 160, which is arranged on the base body 150. The cover body 160 and the base body 150 enclose an installation cavity 166. 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.

[0134] 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 .

[0135] 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 .

[0136] 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 .

[0137] 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.

[0138] 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.

[0139] 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. Second limiting portion 164 mates with second mating portion 162; one of cover 160 and third fan blade 148 is connected to second mating portion 162; and the other of cover 160 and third fan blade 148 is connected to second limiting portion 164. 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.
