Air fryer

Abstract

An air fryer (100), relating to the technical field of cooking devices. The air fryer (100) comprises: a body (110), wherein the body (110) comprises a cooking cavity (1102); and an air guide assembly (120), arranged on the body (110), wherein the air guide assembly (120) comprises an air duct (121), and the air duct (121) communicates the cooking cavity (1102) with a space outside the body (110). On the basis of the characteristic of a fluid medium, in the flow process of the fluid medium, the pressure of a region where a flow rate is large is small, and due to the presence of internal circulating airflow, the pressure inside the cooking cavity (1102) is smaller than the pressure of the external environment of the body (110). Under the action of the pressure difference, external air is pressed into the air duct (121), and airflow introduced from the outside is formed in the air duct (121), so that the cooking cavity (1102) can continuously introduce external air during operation. Therefore, cooking parameters, such as humidity and oxygen content, of the interior of the cooking cavity (1102) can be adjusted by means of external air so as to meet the cooking requirements of a specific food, thereby overcoming the technical defects in the prior art that the cooking parameters such as humidity and oxygen content cannot be adjusted, the cooking requirements of food cannot be met, and the quality of a finished food is poor.

Description

air fryer

[0001] This application claims priority to the Chinese patent applications filed with the China Patent Office on December 15, 2023, with application number "202311731836.4", and with application number "202411455447.8" filed with the China Patent Office on October 17, 2024, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of cooking equipment, and in particular to an air fryer. Background Art

[0003] In the related art, the cooking environment inside the cooking device is a closed environment, and food is cooked into finished food in the closed environment.

[0004] However, in the actual cooking process, since the internal and external airflow cannot be exchanged, cooking parameters such as humidity and oxygen content in the closed environment cannot be adjusted, resulting in technical defects in the cooking equipment that cannot meet food cooking needs and the quality of the finished food is poor.

[0005] Therefore, how to overcome the above-mentioned technical defects has become a technical problem that needs to be solved urgently.

[0006] Application Contents

[0007] This application aims to solve at least one of the technical problems existing in the prior art or related art.

[0008] To this end, the present application proposes an air fryer.

[0009] In view of this, the present application provides an air fryer, which includes: a main body, which includes a cooking cavity; an air induced draft component, which is arranged in the main body, and the air induced draft component includes an air duct, which connects the cooking cavity and the space outside the main body.

[0010] The present application defines an air fryer, which includes a body, which is a frame structure of the air fryer and is used to position, protect, and support other working structures of the air fryer. The body is formed with a cooking cavity, in which food is placed and processed into finished food.

[0011] The air fryer also includes an air induction assembly disposed within the main body. The air induction assembly includes an air duct, a first end of which communicates with the cooking cavity, and a second end of which extends toward the outer surface of the main body and ultimately communicates with the space outside the main body. The air duct is at least partially located outside the cooking cavity. During operation, gas flowing within the cooking cavity forms an internal circulation airflow. Due to the characteristics of a fluid medium, areas of high flow velocity experience lower pressure. Due to the presence of the internal circulation airflow, the pressure within the cooking cavity is lower than the pressure outside the main body. Due to the pressure differential, external gas is forced into the air duct, forming an external air flow within the duct. The external air flow flows from the second end of the air duct to the first end of the air duct. After entering the cooking cavity, the external air flow merges with the internal circulation airflow, allowing the cooking cavity to continuously draw in external air during operation. This utilizes external air to adjust cooking parameters such as humidity and oxygen content within the cooking cavity to meet specific food cooking requirements, addressing technical deficiencies in related art, such as the inability to adjust cooking parameters such as humidity and oxygen content, resulting in poor food quality.

DETAILED DESCRIPTION

[0072] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application 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 in the absence of conflict.

[0073] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0074] The following describes an air fryer according to some embodiments of the present application with reference to Figures 1 to 27.

[0075] As shown in Figures 1 and 2, an embodiment of the present application proposes an air fryer 100, which includes: a main body 110, which includes a cooking cavity 1102; an air induced draft component 120, which is arranged on the main body 110, and the air induced draft component 120 includes an air duct, which connects the cooking cavity and the space outside the main body.

[0076] In some embodiments, an air fryer 100 includes a body 110, wherein the body 110 includes a cooking cavity 1102; an air induction assembly 120 disposed on the body 110, wherein the air induction assembly 120 includes a first air duct 1202 and a second air duct 1204; the second air duct 1204 is located within the cooking cavity 1102, and both a first end and a second end of the second air duct 1204 are in communication with the cooking cavity 1102; the first air duct 1202 is at least partially located outside the cooking cavity 1102, a first end of the first air duct 1202 is in communication with the second air duct 1204, and a second end of the first air duct 1202 is in communication with the exterior of the body 110. This application defines an air fryer 100, which includes a body 110, which serves as a frame structure of the air fryer 100 and is used to position, protect, and support other working structures of the air fryer 100. A cooking cavity 1102 is formed in the body 110 . Food materials are placed in the cooking cavity 1102 and processed into finished food in the cooking cavity 1102 .

[0077] During operation, due to the characteristics of the fluid medium, areas with high flow rates experience lower pressure. Due to the presence of the internally circulating airflow, the location where the air duct connects to cooking cavity 1102 experiences a lower pressure than the environment outside main body 110. This pressure differential forces external air into the duct, creating a new airflow within the duct. This new airflow merges with the internally circulating airflow and ultimately flows into cooking cavity 1102, allowing cooking cavity 1102 to continuously draw in external air during operation. This external air is then used to adjust cooking parameters such as humidity and oxygen content within cooking cavity 1102 to meet the cooking requirements of specific foods, resolving technical deficiencies in related technologies that result in an inability to adjust cooking parameters such as humidity and oxygen content, resulting in poor quality of the finished food.

[0078] Specifically, the air duct accelerates the speed at which outside air enters the cooking cavity 1102, improving the efficiency of outside air participation in the cooking cavity 1102. This increases the amount of aldehydes that characterize food aroma by approximately 20%, enhancing the food's fragrance and reducing the amount of harmful substances produced during the cooking process (acrylamide or heterocyclic amines by approximately 30%). The air fryer 100 also includes an air induction assembly 120 disposed within the body 110. The air induction assembly 120 includes a first air duct 1202 and a second air duct 1204. The first end of the second air duct 1204 communicates with the cooking cavity 1102, and the second end of the second air duct 1204 also communicates with the cooking cavity 1102. The second air duct 1204 is disposed within the cooking cavity 1102. The first end of the first air duct 1202 is connected to the middle section of the second air duct 1204, and the second end of the first air duct 1202 extends toward the outer surface of the main body 110 and is finally connected to the space outside the main body 110, wherein the first air duct 1202 is at least partially located outside the cooking cavity 1102, and when the second air duct 1204 is tightly fitted to the inner wall of the cooking cavity 1102, the first air duct 1202 is located as a whole outside the cooking cavity 1102, and when the second air duct 1204 is away from the inner wall of the cooking cavity 1102, part of the first air duct 1202 extends into the interior of the cooking cavity 1102 and is connected to the second air duct 1204, and the remaining part of the first air duct 1202 is located outside the cooking cavity 1102 and extends toward the outer surface of the main body 110. That is, the air induced component 120 consists of two air ducts, the first air duct 1202 and the second air duct 1204. The second air duct 1204 connects two different areas in the cooking cavity 1102, and the first air duct 1202 connects the cooking cavity 1102 and the outside of the air fryer 100.

[0079] During operation, gas flowing within cooking cavity 1102 flows into second duct 1204 from one of its first and second ends and ultimately exits second duct 1204 from the other end, forming an internal circulation airflow within second duct 1204. Due to the characteristics of a fluid medium, areas with high flow velocity experience lower pressure during flow. Due to the presence of the internal circulation airflow, the pressure within the second duct is lower than the pressure outside body 110. This pressure differential forces external gas into first duct 1202, forming an external airflow within first duct 1202. The external airflow flows from the second end of first duct 1202 to the first end of first duct 1202. After entering second duct 1204, the external airflow merges with the internal circulation airflow and ultimately flows into cooking cavity 1102, enabling continuous intake of external air into cooking cavity 1102 during operation. Thus, cooking parameters such as humidity and oxygen content in the cooking cavity 1102 are adjusted with the help of external air to meet the cooking requirements of specific food, thereby solving the technical defects in related technologies such as the inability to adjust cooking parameters such as humidity and oxygen content, which cannot meet food cooking requirements and result in poor quality of finished food.

[0080] 1 to 16 , arrow a shows the flow direction of the air flow introduced from the outside, and arrow b shows the flow direction of the internal circulating air flow.

[0081] As shown in Figures 2 and 3, in some embodiments of the present application, optionally, the main body 110 also includes an external air introduction port 1106, which is connected to the cooking cavity 1102, and the air induced component 120 includes: a first pipe 122, which is provided on the main body 110, and the first pipe 122 encloses a first air duct 1202; the first end of the first pipe 122 is connected to the external air introduction port 1106, or the first pipe 122 is passed through the external air introduction port 1106.

[0082] In this embodiment, the structure of the air induction assembly 120 is defined. Specifically, the air induction assembly 120 includes a first duct 122 connected to the main body 110. An external air inlet 1106 is defined on the inner wall of the cooking cavity 1102. When the second air duct 1204 is tightly attached to the inner wall of the cooking cavity 1102, the first end of the first duct 122 abuts against the external air inlet 1106. Specifically, an annular boss can be provided on the first end of the first duct 122 to abut against the outer wall of the cooking cavity 1102.

[0083] When the second air duct 1204 is away from the inner wall of the cooking cavity 1102, the first end of the first air duct 1202 is inserted into the cooking cavity 1102 through the external air inlet 1106 and communicates with the second air duct 1204 in the cooking cavity 1102. In this case, the external air inlet 1106 can position the first pipe 122, preventing the first pipe 122 from loosening, misalignment, or even falling off.

[0084] Specifically, the first pipe 122 is arranged at the top of the cooking cavity 1102 . The first pipe 122 extends from top to bottom. Air flow introduced from the outside is poured into the cooking cavity 1102 along the first pipe 122 extending longitudinally.

[0085] As shown in Figures 7 and 8, in some embodiments of the present application, optionally, the air induction component 120 also includes: a second pipe 126, which is disposed in the cooking cavity 1102 and communicates with the first pipe 122, and the second pipe 126 encloses a second air duct 1204.

[0086] In this embodiment, the air induction assembly 120 further includes a second duct 126 disposed within the cooking cavity 1102 and spaced apart from the inner wall of the cooking cavity 1102. The first end of the first duct 122 extends into the cooking cavity 1102 through an air inlet 1106 and communicates with the middle section of the second duct 126. The first duct 122 provides positioning and support for the second duct 126. A bracket connecting the inner wall of the cooking cavity 1102 and the second duct 126 can also be provided to position and support the second duct 126.

[0087] By integrating an independent second duct 126 within cooking cavity 1102, second air duct 1204 can be brought closer to an area within cooking cavity 1102 with higher flow rates. This increases the velocity of the internally circulating airflow within second air duct 1204, correspondingly reducing the pressure within second air duct 1204 and increasing the pressure differential between second air duct 1204 and the external environment. This increased internal and external pressure differential increases the velocity of the airflow introduced into cooking cavity 1102, thereby increasing the air intake rate into cooking cavity 1102 and improving the oxygen content or humidity regulation within cooking cavity 1102. This optimizes the structure of induced draft assembly 120, increases the air intake rate of induced draft assembly 120, broadens the functional coverage of air fryer 100, and improves the quality of cooked food.

[0088] As shown in Figures 4, 5 and 6, in some embodiments of the present application, optionally, the air induced assembly 120 also includes: an air duct plate 124 connected to the body 110, and the air duct plate 124 and the inner wall of the cooking cavity 1102 enclose a second air duct 1204.

[0089] In this embodiment, the air induction assembly 120 further includes an air duct plate 124, which is disposed within the cooking cavity 1102 and connected to the inner wall of the cooking cavity 1102. After the air duct plate 124 is assembled, the air duct plate 124 and the inner wall of the cooking cavity 1102 together enclose a second air duct 1204. Furthermore, the air duct plate 124 blocks the external air intake 1106 on the inner wall of the cooking cavity 1102, ensuring that the external air exhausted from the first duct 122 can flow into the second air duct 1204.

[0090] By providing air duct plate 124, the inner wall of cooking cavity 1102 can be effectively utilized, thereby simplifying the structure of air induction assembly 120 and reducing the cost of air induction assembly 120. Furthermore, assembly can be completed by simply fixing air duct plate 124 to the inner wall of cooking cavity 1102, eliminating the need for independent positioning and support structures, thereby reducing the difficulty of assembling air induction assembly 120.

[0091] As shown in FIG. 4 , FIG. 5 and FIG. 6 , in some embodiments of the present application, optionally, the inner wall of the cooking cavity 1102 includes a planar area 1104 , and the air duct plate 124 and the planar area 1104 enclose a second air duct 1204 .

[0092] In this embodiment, the inner wall of cooking cavity 1102 includes a flat area 1104 and a curved area. Specifically, a portion of flat area 1104 is located at the top of cooking cavity 1102, while another portion of flat area 1104 is located around the sides of cooking cavity 1102. The curved area transitionally connects the flat areas 1104 to enclose cooking cavity 1102.

[0093] On this basis, the air duct plate 124 is connected to the flat area 1104. Compared to connecting the air duct plate 124 to the curved area, connecting the air duct plate 124 to the flat area 1104 can improve the fit between the air duct plate 124 and the inner wall of the cooking cavity 1102, thereby reducing the difficulty of sealing between the air duct plate 124 and the inner wall of the cooking cavity 1102, and preventing the gas in the second air duct 1204 from leaking through the gap between the air duct plate 124 and the inner wall of the cooking cavity 1102, thereby ensuring the strength of the internal circulating airflow and the pressure difference between the inside and outside.

[0094] At the same time, connecting the air duct plate 124 with the planar area 1104 is also beneficial to simplifying the structure of the air duct plate 124 , thereby reducing the process complexity and processing cost of the air duct plate 124 .

[0095] In addition, by enclosing the second air duct 1204 within the plane area 1104 , the resistance of the second air duct 1204 to the internal circulation airflow is reduced, thereby further increasing the flow rate of the internal circulation airflow and increasing the internal and external pressure difference.

[0096] As shown in FIG. 3 and FIG. 5 , in some embodiments of the present application, optionally, a portion of the air duct plate 124 is bent in a direction away from the inner wall of the cooking cavity 1102 .

[0097] In this embodiment, a portion of the air duct plate 124 is curved, bending away from the inner wall of the cooking cavity 1102 to expand the volume of the second flow channel enclosed between the air duct plate 124 and the inner wall of the cooking cavity 1102, thereby ensuring the flow rate of the internal circulating airflow. The remaining portion of the air duct plate 124 is shaped to match the shape of the inner wall of the cooking cavity 1102. When the air duct plate 124 is positioned on a flat surface area 1104 of the inner wall of the cooking cavity 1102, this portion of the air duct plate 124 is a flat plate. When the air duct plate 124 is positioned on a curved surface area of ​​the inner wall of the cooking cavity 1102, this portion of the air duct plate 124 is a curved plate to ensure that it conforms to the inner wall of the cooking cavity 1102 and avoid a gap connecting the second air duct 1204 and the cooking cavity 1102. This ensures the effective introduction of external air and enhances the ability to regulate the internal environment of the cooking cavity 1102.

[0098] As shown in Figure 7, in some embodiments of the present application, optionally, on the second air duct 1204, the area connected to the first end of the first air duct 1202 is the connecting area 1206, the flow area of ​​the first end of the second air duct 1204 is larger than the flow area of ​​the connecting area 1206, and / or the flow area of ​​the second end of the second air duct 1204 is larger than the flow area of ​​the connecting area 1206.

[0099] In this embodiment, the area within second air duct 1204 where it intersects with first air duct 1202 is defined as connection area 1206. Air introduced from the outside flows through the first end of first air duct 1202 and into connection area 1206. Based on this, the flow area at the first end of second air duct 1204 is S1, the flow area at the second end of second air duct 1204 is S2, and the flow area of ​​connection area 1206 is S3. S1, S2, and S3 must satisfy the following conditions: S3 < S1, and / or S3 < S2.

[0100] Specifically, when the direction of gas flow in the cooking cavity 1102 is relatively stable and the internal circulating airflow can be guaranteed to enter the second air duct 1204 from the first end, it is sufficient to satisfy S3 < S1. Correspondingly, when the internal circulating airflow can be guaranteed to enter the second air duct 1204 from the second end, it is sufficient to satisfy S3 < S2. When the direction of gas flow in the cooking cavity 1102 is unstable and the inflow end of the internal circulating airflow cannot be guaranteed, both S3 < S1 and S3 < S2 must be satisfied. The connecting area 1206 has a certain extension length, that is, the connecting area 1206 includes multiple S3s, and all of the multiple S3s must meet the above conditions.

[0101] By limiting the aforementioned flow area relationship, the internal circulating airflow will pass through at least one section with a reduced flow area in its flow direction. Based on the principle of fluid continuity, the internal circulating airflow increases in velocity when it reaches the connected area 1206 with a smaller flow area. This correspondingly reduces the pressure in the connected area 1206, and increases the pressure difference between the connected area 1206 and the external environment. This increased internal and external pressure difference increases the velocity of the airflow introduced from the outside, thereby increasing the air intake rate into the cooking cavity 1102 and improving the oxygen content or humidity regulation within the cooking cavity 1102. This results in the technical benefits of optimizing the structure of the induced draft assembly 120, increasing the air intake rate of the induced draft assembly 120, broadening the functional coverage of the air fryer 100, and improving the quality of the cooked food.

[0102] As shown in Figure 7, in some embodiments of the present application, optionally, the flow area of ​​the second air duct 1204 gradually decreases in the direction from the first end of the second air duct 1204 to the connecting area 1206; the flow area of ​​the second air duct 1204 gradually decreases in the direction from the second end of the second air duct 1204 to the connecting area 1206.

[0103] In this embodiment, the shape of second air duct 1204 is defined. Specifically, the flow area of ​​second air duct 1204 gradually decreases from the first end of second air duct 1204 to the connection area 1206, forming an air duct with a gradually decreasing cross-sectional area between the first end of second air duct 1204 and the connection area 1206. After the gas within cooking cavity 1102 enters second air duct 1204 from the first end, the gradually decreasing flow area continuously accelerates the airflow, increasing the flow rate of the internal circulating airflow in the connection area 1206, thereby reducing the pressure in the connection area 1206 and increasing the pressure difference between the connection area 1206 and the external environment.

[0104] Specifically, the flow area of ​​second air duct 1204 gradually decreases in the direction from the second end of second air duct 1204 to connecting region 1206, thereby forming an air duct with a gradually decreasing cross-sectional area between the second end of second air duct 1204 and connecting region 1206. After the gas in cooking cavity 1102 enters second air duct 1204 from the second end, the gradually decreasing flow area continuously accelerates the airflow, thereby increasing the flow rate of the internal circulating airflow in connecting region 1206, thereby reducing the pressure in connecting region 1206 and increasing the pressure difference between connecting region 1206 and the external environment.

[0105] By increasing the internal and external pressure difference, the velocity of the air flow from the outside is increased, thereby increasing the air intake rate into the cooking cavity 1102 and improving the ability of the induced draft assembly 120 to regulate the oxygen content or humidity within the cooking cavity 1102. This results in the technical effect of optimizing the structure of the induced draft assembly 120, increasing the air intake rate of the induced draft assembly 120, broadening the functional coverage of the air fryer 100, and improving the quality of the cooked food.

[0106] As shown in FIG. 7 , in some embodiments of the present application, optionally, the flow area of ​​the second end of the first air duct 1202 is larger than the flow area of ​​the first end of the first air duct 1202 .

[0107] In this embodiment, the flow area at the second end of the first air duct 1202 is S4, that is, the cross-sectional area of ​​the inlet of the first air duct 1202 is S4. Correspondingly, the flow area at the first end of the first air duct 1202 is S5, that is, the cross-sectional area of ​​the outlet of the first air duct 1202 is S5. S4 and S5 must satisfy the following condition: S4>S5.

[0108] By limiting the aforementioned flow area relationship, the airflow introduced from the outside will pass through at least one section with a reduced flow area in its flow direction. Based on the principle of fluid continuity, the flow velocity of the airflow from the outside will increase when it reaches the section with a reduced flow area, thereby increasing the air introduction rate into cooking cavity 1102 and improving the regulation of the oxygen content or humidity within cooking cavity 1102. This resolves the technical drawbacks of low ventilation efficiency and poor food quality in related technologies. This further optimizes the structure of induced draft assembly 120, increases the air intake rate of induced draft assembly 120, expands the functional coverage of air fryer 100, and improves the quality of cooked food.

[0109] As shown in FIG. 7 , in some embodiments of the present application, optionally, the flow area of ​​the first air duct 1202 gradually decreases in a direction from the second end of the first air duct 1202 to the first end of the first air duct 1202 .

[0110] In this embodiment, the shape of the first air duct 1202 is defined. Specifically, the flow area of ​​the first air duct 1202 gradually decreases in the direction from the second end of the first air duct 1202 to the first end of the first air duct 1202, thereby forming a first air duct 1202 with a gradually decreasing cross-sectional area. That is, the cross-sectional area of ​​the first air duct 1202 gradually decreases in the flow direction of the air flow introduced from the outside. After the gas in the external environment is pressed into the first air duct 1202 by the pressure difference, the gradually decreasing flow area can provide continuous acceleration for the air flow introduced from the outside, thereby increasing the flow rate of the air flow introduced from the outside in the first air duct 1202.

[0111] This increases the air intake rate into the cooking cavity 1102 and the ability of the draft assembly 120 to regulate the oxygen content or humidity within the cooking cavity 1102. This optimizes the structure of the draft assembly 120, increases the air intake rate of the draft assembly 120, broadens the functional scope of the air fryer 100, and improves the quality of cooked food.

[0112] As shown in Figures 8, 11 and 14, in some embodiments of the present application, optionally, the air fryer 100 also includes: a flow regulating component 170, connected to the air induced component 120, and the flow regulating component 170 is used to regulate the flow of the first air duct 1202 and / or the second air duct 1204.

[0113] Furthermore, the air fryer 100 further includes a flow regulating assembly 170 connected to the air induction assembly 120. The air fryer 100 can adjust the flow rate in the first air duct 1202 and / or the second air duct 1204 by controlling the operating state of the flow regulating assembly 170. Specifically, when a closed cooking environment is required, the flow regulating assembly 170 is controlled to close the first air duct 1202 and / or the second air duct 1204 to block the internal circulation airflow within the first air duct 1202 and / or the second air duct 1204, thereby stopping the introduction of external air. When the introduction of external air is required, the flow regulating assembly 170 is controlled to open the first air duct 1202 and / or the second air duct 1204 to enable internal circulation airflow within the second air duct 1204, thereby introducing external air into the cooking cavity 1102 by creating a pressure difference between the inside and the outside. The opening of the second air duct 1204 can be adjusted by controlling the flow regulating component 170 to adjust the flow rate and flow of the internal circulation airflow in the second air duct 1204 to correspondingly adjust the amount of external air introduced and the introduction rate of external air.

[0114] Thus, by providing the flow regulating assembly 170, the air fryer 100 can control the flow regulating assembly 170 to turn the ventilation process on and off, and adjust the ventilation rate, thereby ensuring that the current external air introduction rate is adapted to the cooking process and that parameters such as the humidity and oxygen content within the cooking chamber 1102 meet cooking requirements. This optimizes the structure of the air fryer 100, enhances the practicality and controllability of the air fryer 100, improves the quality of the cooked food, and enhances the user experience.

[0115] As shown in Figures 8, 9 and 10, in some embodiments of the present application, optionally, the flow regulating assembly 170 includes: a first driving member 172, which is provided in the air induced assembly 120; a first valve plate 174, which is connected to the first driving member 172, and the first driving member 172 is used to drive the first valve plate 174 to move; wherein, the first valve plate 174 includes a first position and a second position, when the first valve plate 174 is in the first position, the first valve plate 174 blocks the second air duct 1204; when the first valve plate 174 is in the second position, the first valve plate 174 opens the second air duct 1204.

[0116] In this embodiment, the structure of the flow regulating assembly 170 is defined. Specifically, the flow regulating assembly 170 includes a first driving member 172 and a first valve disc 174. The first valve disc 174 is disposed at the openings at both ends of the second air duct 1204 and is movable relative to the second air duct 1204. The first driving member 172 is fixed to the flow regulating assembly 170 or the body 110 and is connected to the first valve disc 174. When the first driving member 172 is activated, it can drive the first valve disc 174 to move between a first position and a second position.

[0117] When the first actuator 172 drives the first valve disc 174 to the first position, the first valve disc 174 covers the first or second end of the second air duct 1204, blocking the internal circulation airflow within the second air duct 1204 and thereby disabling the external air intake function. When the first actuator 172 drives the first valve disc 174 to the second position, the first valve disc 174 is offset from the first or second end of the second air duct 1204, eliminating the impact of the first valve disc 174 on the internal circulation airflow and ensuring smooth flow of the internal circulation airflow. This allows the introduction of external airflow via the internal and external pressure differential. Furthermore, when the first valve disc 174 moves between the first and second positions, a portion of the port of the second air duct 1204 is blocked by the first valve disc 174, while the remaining portion is open. This allows the port of the second air duct 1204 to be opened, thereby adjusting the flow rate and velocity of the internal circulation airflow. This ensures that the current external air intake rate is compatible with the cooking process and that parameters such as the humidity and oxygen content within the cooking chamber 1102 meet cooking requirements.

[0118] This solves the technical defects of the related art, such as the uncontrollable ventilation process and the inability to guarantee food quality. Furthermore, the structure of the air fryer 100 is optimized, the practicality and controllability of the air fryer 100 are improved, the quality of the cooked food is improved, and the user experience is enhanced.

[0119] As shown in Figures 11, 12, 13 and 14, in some embodiments of the present application, optionally, the flow regulating assembly 170 includes: a second driving member 176, which is provided in the air induced assembly 120; a second valve plate 178, which is connected to the second driving member 176, and the second driving member 176 is used to drive the second valve plate 178 to move; wherein, the second valve plate 178 includes a third position and a fourth position, when the second valve plate 178 is in the third position, the second valve plate 178 blocks the first air duct 1202; when the second valve plate 178 is in the fourth position, the second valve plate 178 opens the first air duct 1202.

[0120] In this embodiment, the structure of the flow regulating assembly 170 is defined. Specifically, the flow regulating assembly 170 includes a second driving member 176 and a second valve disc 178. The second valve disc 178 is disposed at the openings at both ends of the first air duct 1202 and is movable relative to the first air duct 1202. The second driving member 176 is fixed to the flow regulating assembly 170 or the body 110 and is connected to the second valve disc 178. When the second driving member 176 is activated, it can drive the second valve disc 178 to move between a third position and a fourth position.

[0121] When the second driving member 176 drives the second valve disc 178 to move to the third position, the second valve disc 178 can cover the first end or the second end of the first air duct 1202, thereby blocking the flow of external air into the first air duct 1202, thereby turning off the external air intake function. When the second driving member 176 drives the second valve disc 178 to move to the fourth position, the second valve disc 178 is offset from the first end or the second end of the first air duct 1202, eliminating the impact of the second valve disc 178 on the flow of external air, ensuring the smooth flow of external air, and thus introducing the external air flow through the internal and external pressure difference. On this basis, if the second valve plate 178 moves to between the third position and the fourth position, part of the area of ​​the port of the first air duct 1202 is blocked by the second valve plate 178, and the remaining area is opened, thereby realizing the opening adjustment of the port of the first air duct 1202, so as to specifically adjust the flow rate and flow rate of the air flow introduced from the outside, ensure that the current external air introduction rate can adapt to the cooking process, and ensure that the humidity value, oxygen content and other parameters in the cooking cavity 1102 can meet the cooking requirements.

[0122] This solves the technical defects of the related art, such as the uncontrollable ventilation process and the inability to guarantee food quality. Furthermore, the structure of the air fryer 100 is optimized, the practicality and controllability of the air fryer 100 are improved, the quality of the cooked food is improved, and the user experience is enhanced.

[0123] As shown in Figure 1, in some embodiments of the present application, optionally, the air fryer 100 also includes: an inner pot 130, which is arranged in the cooking cavity 1102, and the inner pot 130 includes a accommodating cavity and an opening; a fan 140, which is arranged in the main body 110 and is opposite to the opening of the inner pot 130, and the second air duct 1204 is located on the peripheral side of the fan 140.

[0124] In this embodiment, the air fryer 100 also includes an inner pot 130 and a fan 140. The inner pot 130 is removably mounted within the cooking chamber 1102. In the case of the air fryer 100, the inner pot 130 is a removable frying tub. Ingredients are placed in the inner pot 130 and cooked into finished food. The inner pot 130 provides convenient access to food, optimizing the user experience.

[0125] By providing fan 140, air can be supplied to the ingredients in inner pot 130, thereby producing finished food with a quality and taste that meets user requirements. Furthermore, fan 140 can accelerate the internal circulating airflow within second air duct 1204, thereby increasing the pressure difference between second air duct 1204 and the external environment by increasing the flow rate of the internal circulating airflow. This increased pressure difference between the internal and external environments increases the flow rate of the airflow introduced from the outside, thereby increasing the air introduction rate into cooking cavity 1102 and improving the effect of regulating the oxygen content or humidity within cooking cavity 1102. This, in turn, optimizes the structure of induced draft assembly 120, increases the air intake rate of induced draft assembly 120, broadens the functional coverage of air fryer 100, and improves the quality of cooked food.

[0126] As shown in Figures 1 and 4, in some embodiments of the present application, optionally, the fan 140 includes: a motor 142, connected to the body 110; fan blades 144, connected to the motor 142, and the motor 142 is used to drive the fan blades 144 to rotate; wherein the second air duct 1204 extends on a circle with the rotating shaft 1642 of the fan blade 144 as the axis.

[0127] In this embodiment, fan 140 includes blades 144 located within cooking cavity 1102 and facing the opening of inner pot 130. When fan 140 is turned on, the rotating front sides of blades 144 generate a first airflow that pours into inner pot 130. Simultaneously, the rotating sides of blades 144 generate a spiral airflow that flows along the sidewalls of cooking cavity 1102. This spiral airflow actively flows into second air duct 1204, cooperating with first air duct 1202 to draw in outside air.

[0128] On this basis, the second air duct 1204 is arranged around the fan blade 144, and the second air duct 1204 extends on a circle with the rotating shaft 1642 of the fan blade 144 as the axis, or the air outlet side of the fan blade faces the air inlet end of the second air duct 1204, or the air return side of the fan blade faces the air inlet end of the second air duct 1204, so that the extension direction of the second air duct 1204 matches the flow direction of the spiral airflow around the fan blade 144, thereby reducing the resistance of the second air duct 1204 to the internal circulating airflow, thereby increasing the flow rate of the internal circulating airflow in the second air duct 1204 and reducing the pressure in the second air duct 1204, thereby improving the effect of introducing air from the outside by increasing the pressure difference between the inside and the outside. Ultimately, the technical effect of optimizing the structure of the air induction component 120, increasing the air intake rate of the air induction component 120, broadening the functional coverage of the air fryer 100, and improving the quality of the cooked food is achieved.

[0129] As shown in Figure 15, in some embodiments of the present application, optionally, the direction perpendicular to the cross-section of the first end of the second air duct 1204 is a first direction, and the angle between the first direction and the tangential direction of the fan blade 144 is a first angle; the direction perpendicular to the cross-section of the second end of the second air duct 1204 is a second direction, and the angle between the second direction and the tangential direction of the fan blade 144 is a second angle; the range of the first angle is: greater than or equal to 0°, and less than 30°; and / or the range of the second angle is: greater than or equal to 0°, and less than 30°.

[0130] In FIG15 , arrow c shows the tangential direction of the blade 144 , and α is the first angle or the second angle.

[0131] In this embodiment, second air duct 1204 is arranged around blade 144. The opening of the first end of second air duct 1204 is oriented in a first direction, and the opening of the second end of second air duct 1204 is oriented in a second direction. The angle between the first direction and the tangential direction of blade 144 is the first angle, and the angle between the second direction and the tangential direction of blade 144 is the second angle.

[0132] During operation of the air fryer 100, if the fan blades 144 rotate only in a single rotational direction, the rotational direction of the second internal circulating airflow generated thereby is fixed and consistent with the rotational direction of the fan blades 144. The second internal circulating airflow flows into the second air duct 1204 from one of the first end and the second end of the second air duct 1204 and flows out of the air duct from the other of the first end and the second end. Specifically, if the second internal circulating airflow flows into the second air duct 1204 from the first end, the first angle must be greater than or equal to 0° and less than 30°. If the second internal circulating airflow flows into the second air duct 1204 from the second end, the second angle must be greater than or equal to 0° and less than 30°.

[0133] Correspondingly, during operation of the air fryer 100, if the fan blades 144 can rotate forward or reverse, the rotational direction of the second internal circulating airflow generated thereby is not fixed. The second internal circulating airflow may enter the second air duct 1204 from the first end or from the second end. To this end, the first angle must be greater than or equal to 0° and less than 30°, and the second angle must be greater than or equal to 0° and less than 30°.

[0134] Because the instantaneous flow direction of the second internal circulating airflow generated by the rotation of blades 144 is consistent with the tangential direction of blades 144, the first angle and the second angle can reflect the angle between the air flow direction and the orientation of the entrance of second air duct 1204. By limiting this angle to a range greater than or equal to 0° and less than 30°, it is ensured that at least a portion of the entrance of second air duct 1204 is exposed to the movement trajectory of the second internal circulating airflow, ensuring that a portion of the second internal circulating airflow can directly enter the second air duct 1204 without changing its flow direction.

[0135] Compared to a solution where the second internally circulating airflow is redirected before entering the second air duct 1204, introducing the second internally circulating airflow directly into the second air duct 1204 can increase the flow rate and velocity of the airflow in the second air duct 1204. This increased flow rate can correspondingly reduce the pressure in the second air duct 1204, thereby increasing the pressure difference between the second air duct 1204 and the external environment. This increased internal and external pressure difference increases the velocity of the airflow introduced from the outside, thereby increasing the air intake rate into the cooking cavity 1102 and improving the oxygen content or humidity regulation within the cooking cavity 1102. This optimizes the structure of the air induction assembly 120, increases the air intake rate of the air induction assembly 120, expands the functional coverage of the air fryer 100, and improves the quality of the cooked food.

[0136] Specifically, if the first angle and the second angle simultaneously meet the condition of being greater than or equal to 0° and less than 30°, it can ensure that at least a portion of the area in the outlet of the second air duct 1204 is exposed to the original movement trajectory of the second internal circulation airflow, ensuring that part of the second internal circulation airflow can pass through the second air duct 1204 without changing the flow direction, so as to reduce the resistance of the second internal circulation airflow in the second air duct 1204, further reduce the pressure in the second air duct 1204, and increase the pressure difference between the inside and outside.

[0137] Specifically, the first angle can be selected to be 0°, that is, the direction of the opening of the first end is consistent with the tangent direction of the fan blade 144, so as to maximize the flow rate and flow of the gas entering the second air duct 1204.

[0138] Specifically, the second angle can be selected to be 0°, that is, the direction of the opening of the first end is consistent with the tangent direction of the fan blade 144, so as to maximize the flow rate and flow of the gas entering the second air duct 1204.

[0139] As shown in FIG. 1 , in some embodiments of the present application, optionally, the air fryer 100 further includes: a heating component 150 , which is disposed on the body 110 and located between the fan 140 and the inner pot 130 .

[0140] In this embodiment, the air fryer 100 further includes a heating assembly 150 disposed within the cooking cavity 1102 and positioned between the fan 140 and the inner pot 130. When activated, the heating assembly 150 heats the first airflow directed toward the inner pot 130 and / or the blades 144 of the fan 140, thereby heating the first airflow to a high temperature. This high temperature airflow then toasts the outer surface of the food, resulting in a golden, crispy crust. This improves the quality of the cooked food and enhances the user experience.

[0141] Specifically, the heating component 150 includes a heating pipe, which is coiled and avoids the front area of ​​the fan 140 to prevent the heating component 150 from affecting the flow of the first airflow.

[0142] The heating component 150 also includes an electromagnetic heating element, which can generate an electric field when turned on. The magnetic fan blades 144 are heated up under the action of the electric field to directly blow out a first airflow with a higher temperature.

[0143] In some embodiments of the present application, the air fryer 100 further includes a fan 164, which is disposed in the first air duct 1202. The airflow flowing into the first air duct 1202 can drive the fan 164 to rotate. By providing a visible fan 164, the incoming airflow can be externalized, allowing the user to determine whether there is an external airflow by observing whether the fan 164 is rotating, and to determine the strength of the external airflow by observing the rotation speed of the fan 164, thereby providing convenient conditions for the user to control the air fryer 100.

[0144] In some embodiments, the air fryer 100 further includes a transparent cover 162, which is disposed on the body 110 and opposite to the fan 164. In other words, the transparent cover 162 can not only play a role in waterproofing and dustproofing, but also play a role in displaying the fan 164.

[0145] As shown in Figures 16, 17, 18 and 19, in some embodiments of the present application, optionally, the air fryer 100 also includes: a base 160, which is provided on the main body 110; a cover 162, which covers the base 160, and the base 160 and the cover 162 enclose an installation cavity 1602, and the installation cavity 1602 is connected to the second end of the first air duct 1202; a fan 164, which is provided in the installation cavity 1602, and the airflow flowing into the first air duct 1202 can drive the fan 164 to rotate.

[0146] In this embodiment, the air fryer 100 further includes a base 160, a lid 162, and a fan 164. The base 160 is embedded in the outer surface of the body 110, with a portion of the base 160 exposed outside the body 110. A through hole is provided at the bottom of the base 160, which communicates with the second end of the first air duct 1202. The fan 164 is rotatably connected to the base 160. The lid 162 is fitted over the base 160. After the lid 162 is assembled, the lid 162 and the base 160 enclose an installation cavity 1602, which communicates with the first air duct 1202 via the through hole. The lid 162 is also provided with a second air inlet 1622, which communicates with the installation cavity 1602. During the cooking process, the air flow introduced from the outside, which is pressed in by the pressure difference between the inside and the outside, first enters the installation cavity 1602 through the second air inlet 1622 and flows toward the through hole. During this process, the air flow introduced from the outside can drive the fan 164 to rotate. The faster the flow rate of the air flow introduced from the outside, the faster the rotation speed of the fan 164. The user can observe the status of the internal fan 164 through the air inlet on the cover 162. Afterwards, the air flow introduced from the outside enters the cooking cavity 1102 through the through hole, the first air duct 1202 and the second air duct 1204 to meet the air supply needs of the cooking cavity 1102.

[0147] By providing a visible fan 164, the incoming airflow can be externalized. This allows the user to determine the presence of external airflow by observing the rotation of fan 164, and to determine the strength of the external airflow by observing the rotation speed of fan 164, providing convenient control over the air fryer 100. Furthermore, compared to solutions that use an air volume sensor to detect the incoming airflow, the proposed externalized fan 164 solution can reduce the structural complexity and production cost of the air fryer 100 while still meeting the requirements for incoming airflow feedback. Furthermore, the rotating fan 164 can enhance the enjoyment of the air fryer 100, further improving the user experience.

[0148] In some embodiments of the present application, optionally, the cover 162 is a light-transmitting cover.

[0149] In this embodiment, the cover 162 is made of a light-transmitting material to produce a light-transmitting cover.

[0150] By providing a translucent cover, the user can observe the status of the fan 164 inside the cover 162 through the cover 162, thereby improving the externalization effect of the fan 164 on the air flow introduced from the outside and reducing the difficulty for the user to observe the fan 164.

[0151] Specifically, the cover 162 can be made of materials such as glass and plastic.

[0152] As shown in Figures 16 and 19, in some embodiments of the present application, optionally, the air fryer 100 also includes: a base 160, which is provided on the main body 110; a cover 162, which covers the base 160; the base 160 includes a first air inlet 1604, and the cover 162 includes a second air inlet 1622; the cover 162 can move relative to the base 160; wherein, when the cover 162 is in the fifth position, the second air inlet 1622 is opposite to the first air inlet 1604; when the cover 162 is in the sixth position, the second air inlet 1622 and the first air inlet 1604 are staggered, and the cover 162 blocks the first air inlet 1604.

[0153] In this embodiment, the base 160 is embedded in the outer surface of the body 110, so that the base 160 is partially exposed outside the body 110. A cavity is formed inside the base 160. A through hole is provided at the bottom of the base 160 to connect to the cavity. The through hole is connected to the second end of the first air duct 1202. The base 160 is also provided with a first air inlet 1604 to connect to the cavity, and the first air inlet 1604 is clear of the through hole at the bottom of the base 160. The cover 162 is connected to the base 160 and can move relative to the base 160. The cover 162 is provided with a second air inlet 1622 that extends through the cover 162. After the cover 162 is assembled, the cover 162 covers the cavity.

[0154] The cover 162, which is movable relative to the base 160, has a fifth position and a sixth position. When the cover 162 is moved to the fifth position, the first air inlet 1604 and the second air inlet 1622 are aligned, allowing the cavity to communicate with the outside environment through the first and second air inlets 1604, 1622. In this position, external air is forced into the cavity due to the pressure difference between the inside and outside. It then flows through the through-holes into the first air duct 1202, forming an external air flow within the first air duct 1202. Ultimately, the external air flow enters the cooking cavity 1102, thereby activating the external air intake function. When the cover 162 is moved to the sixth position, the second air inlet 1622 is offset from the first air inlet 1604. The cover 162 blocks the first air inlet 1604, preventing external air from entering the first air inlet 1604 and effectively closing the first air inlet 1604, thereby disabling the external air intake function. In addition, the position of the cover 162 can be adjusted to block a portion of the first air inlet 1604 to adjust the opening of the first air inlet 1604, thereby adjusting the rate of introduction of air from the outside.

[0155] Thus, by providing base 160 and lid 162, the user can actively control the start and stop of the outside air intake function by operating lid 162. Specifically, first air inlet 1604 can be closed when a closed cooking environment is desired, and opened when the internal environment of cooking cavity 1102 needs to be adjusted. Furthermore, after the outside air intake function is activated, the outside air intake rate can be controlled to ensure that the current outside air intake rate is adapted to the cooking process and that parameters such as humidity and oxygen content within cooking cavity 1102 meet cooking requirements. This optimizes the structure of air fryer 100, enhances the practicality and controllability of air fryer 100, improves the quality of cooked food, and enhances the user experience.

[0156] As shown in Figure 16, in some embodiments of the present application, optionally, the seat body 160 is connected to the second end of the first air duct 1202, the seat body 160 is at least partially located on the outside of the main body 110, and the first air inlet 1604 is located on the peripheral side wall of the seat body 160; the cover body 162 is rotatably connected to the seat body 160, and the second air inlet 1622 is located on the peripheral side of the seat body 160.

[0157] In this embodiment, the seat body 160 is installed at a predetermined position on the main body 110. After the assembly of the seat body 160 is completed, at least part of the seat body 160 is located on the outside of the main body 110, so as to reduce the difficulty of assembling the cover body 162 and operating the cover body 162, and provide convenient conditions for the user to control the function of introducing air from the outside.

[0158] On this basis, the first air inlet 1604 is set on the peripheral side wall of the base body 160, and the first air inlet 1604 extends in the radial direction of the first base body 160. After the first air inlet 1604 is opened, the external air flows from the four sides of the base body 160 to the cavity inside the base body 160.

[0159] On this basis, a circumferential opening is formed on the side surface of the cover 162 to form a second air inlet 1622. The cover 162 is rotatable. When the second air inlet 1622 of the cover 162 is rotated to a fifth position, offset from the first air inlet 1604 and opposite the side wall of the base 160, the first air inlet 1604 is closed and the air inlet assembly 120 is closed. When the second air inlet 1622 of the cover 162 is rotated to overlap at least a portion of the first air inlet 1604, the first air inlet 1604 is opened and the air inlet assembly 120 is turned on. The amount of air introduced from the outside can be controlled by rotating the cover 162.

[0160] Under this structure, external air is gathered from the periphery of the cavity toward the center. The fan 164 arranged in the cavity rotates axially under force. By forming the above-mentioned airflow, the force uniformity applied to the fan 164 in all directions can be improved, thereby preventing problems such as fan 164 getting stuck or misaligned. This further improves the rotation stability of the fan 164, reduces the failure rate of the fan 164, and improves the reliability of the external air introduction function.

[0161] In some embodiments of the present application, optionally, the base body 160 is connected to the second end of the first air duct 1202, the base body 160 is located on the inner side of the main body 110, and the first air inlet 1604 is located on the upper side wall of the base body 160; the switch member is rotatably connected to the base body 160, and the second air inlet 1622 is located on the upper side of the base body 160.

[0162] As shown in Figure 17, in some embodiments of the present application, optionally, the fan 164 includes a rotating shaft 1642 and a plurality of blades 1645, the rotating shaft 1642 is connected to the base 160, and the plurality of blades 1645 are arranged along the circumference of the rotating shaft 1642; wherein the number of the plurality of blades 1645 is less than or equal to three.

[0163] In this embodiment, fan 164 includes a rotating shaft 1642 and a plurality of blades 1645. Rotating shaft 1642 is connected to base 160, and blades 1645 are arranged circumferentially along rotating shaft 1642. Rotating shaft 1642 is connected to base 160, thereby supporting the rotation of fan 164. When air fryer 100 is in operation, the flow of air within mounting cavity 1602 and first air duct 1202 drives fan 164 to rotate along rotating shaft 1642.

[0164] Specifically, the rotating shaft 1642 can be rotatably connected to the cover body 162 , and the rotating shaft 1642 can also be rotatably connected between the cover body 162 and the base body 160 through an extended support component to enhance the rotation effect of the fan 164 .

[0165] Furthermore, a groove can be provided on the rotating shaft 1642 to be connected with the support components extending from the cover body 162 and the base body 160 in a nested manner, leaving a gap at the connection to reduce the contact area between the rotating shaft 1642 and the support components, thereby reducing the friction resistance when the fan 164 rotates and improving the rotation efficiency of the fan 164.

[0166] In this embodiment, fan 164 in mounting cavity 1602 includes multiple blades 1645. These blades 1645 are arranged circumferentially around rotational shaft 1642, thereby increasing the efficiency of fan 164 in converting wind energy into kinetic energy. The number of blades 1645 being three or fewer reduces the weight of fan 164, thereby increasing its rotational efficiency.

[0167] Furthermore, a material with low density can be used to make the blades 144 of the fan 164, which can increase the wind receiving area of ​​the blades 144 while reducing the weight of the fan 164, thereby improving the working efficiency of the fan 164 and making the fan 164 rotate more obviously under the action of gas flow.

[0168] As shown in Figure 18, in some embodiments of the present application, optionally, the air fryer 100 further includes: a limiting component 232, the fan 164 is arranged on the upper side of the limiting component 232, and is connected to the limiting component 232. The limiting component 232 limits the movement of the fan 164 in the direction of the limiting component 232, and the fan 164 can rotate relative to the limiting component 232.

[0169] The fan 164 is disposed on the upper side of the limit assembly 232 and is connected to the limit assembly 232. The limit assembly 232 limits the movement of the fan 164 in the direction of the limit assembly 232, and the fan 164 can rotate relative to the base 160. The fan 164 in the fan 164 assembly is disposed on the upper side of the limit assembly 232. By providing the limit assembly 232 to limit the fan 164, it can be prevented from falling off. At the same time, the provision of the limit assembly 232 can reduce the contact area between the fan 164 and the rotating fan 164 during rotation, thereby reducing friction. When air flows through the fan 164, the rotation effect of the fan 164 can be improved, making it easier for the user to observe the rotation of the fan 164 and improving the user experience. At the same time, reducing friction can reduce wear on the fan 164, thereby extending the life of the product.

[0170] As shown in Figure 18, in some embodiments of the present application, optionally, the limiting assembly 232 also includes: a first matching portion 240, the first matching portion 240 is connected to one of the seat body 160 and the fan 164, a first limiting portion 2324, the first limiting portion 2324 is connected to the other of the seat body 160 and the fan 164, and the first limiting portion 2324 is matched with the first matching portion 240.

[0171] In this technical solution, the fan 164 assembly further includes a first mating portion 240 and a first limiting portion 2324. The first mating portion 240 is connected to one of the base 160 and the fan 164, and the first limiting portion 2324 is connected to the other of the base 160 and the fan 164. The first limiting portion 2324 mates with the first mating portion 240. By providing the first mating portion 240 and the first limiting portion 2324 to limit the position of the fan 164, the stability of the fan 164 can be improved, and the fan 164 can be prevented from falling off.

[0172] In some embodiments, there is a gap between the first matching portion 240 and the circumferential side of the first limiting portion 2324, so the friction resistance is small, thereby reducing the rotation resistance of the fan.

[0173] As shown in FIG. 18 , in some embodiments of the present application, optionally, the first limiting portion 2324 is provided with a first groove 234 , and the first matching portion 240 is embedded in the first groove 234 .

[0174] For example, the fan has a first limiting portion 2324 , that is, the fan is provided with a first groove 234 , and the base has a first matching portion 240 , which is a protruding structure embedded in the first groove 234 .

[0175] In this technical solution, the first limiting portion 2324 is provided with a first groove 234, and the first matching portion 240 is embedded in the first groove 234. By arranging the first matching portion 240 to be embedded in the first groove 234, the contact area between the first limiting portion 2324 and the first matching portion 240 can be reduced when the fan 164 rotates, thereby reducing the frictional resistance experienced by the first limiting portion 2324 during rotation.

[0176] As shown in Figure 18, in some embodiments of the present application, optionally, the limiting assembly 232 also includes: a second matching portion 250, the second matching portion 250 is connected to one of the cover body 162 and the fan 164; a second limiting portion 2322, the second limiting portion 2322 is connected to the other of the cover body 162 and the fan 164, and the second limiting portion 2322 cooperates with the second matching portion 250.

[0177] In this technical solution, the fan 164 assembly also includes a second matching portion 250 and a second limiting portion 2322, the second matching portion 250 is connected to one of the cover body 162 and the fan 164; the second limiting portion 2322 is connected to the other of the cover body 162 and the fan 164, and the second limiting portion 2322 cooperates with the second matching portion 250. By setting the second matching portion 250 and the second limiting portion 2322 to limit the position of the fan 164, the stability of the fan 164 can be improved and the fan 164 can be prevented from falling off.

[0178] In some embodiments, there is a gap between the second matching portion 250 and the second limiting portion 2322 along the axial direction and the circumferential side, so the friction resistance is small, thereby reducing the rotation resistance of the fan.

[0179] As shown in FIG. 18 , in some embodiments of the present application, optionally, the second limiting portion 2322 is provided with a second groove 236 extending along the axial direction, and the second matching portion 250 is embedded in the second groove 236 .

[0180] In this technical solution, by arranging the second matching portion 250 to be embedded in the second groove 236, the contact area between the second limiting portion 2322 and the second matching portion 250 can be reduced when the fan 164 rotates, thereby reducing the friction resistance encountered by the second limiting portion 2322 during rotation.

[0181] For example, the fan 164 has a second limiting portion 2322 , that is, the fan 164 is provided with a second groove 236 , and the cover 162 has a second matching portion 250 , which is a protrusion embedded in the second groove 236 .

[0182] As shown in Figures 20, 21, 22 and 24, an embodiment of the present application proposes an air fryer 100, which includes: a main body 110, which includes a cooking cavity 1102; an air induced draft component 120, which is provided on the main body 110, and the air induced draft component 120 includes an air duct 121, which connects the cooking cavity 1102 and the space outside the main body 110; a liquid delivery component 180, which is connected to the air duct 121, and the liquid delivery component 180 is used to deliver water mist into the air duct 121.

[0183] In FIG20 , arrow b shows the flow direction of the internal circulating air flow, and arrow d shows the flow direction of the air flow introduced from the outside.

[0184] The present application defines an air fryer 100, which includes a liquid delivery component 180. The liquid delivery component 180 is arranged on the main body 110 and is connected to the air induced component 120. The liquid delivery component 180 can produce water mist during operation and discharge the water mist into the air duct 121. Thereafter, the water mist enters the cooking cavity 1102 along with the air flow introduced from the outside. The cooking cavity 1102 is humidified with the help of the air flow introduced from the outside and the water mist, so that the humidity value in the cooking cavity 1102 can meet the cooking requirements of the food.

[0185] Thus, by providing the air induced component 120 and the liquid delivery component 180, the air fryer 100 can adjust the humidity and oxygen content within the cooking cavity 1102 by means of the air induced component 120 and the liquid delivery component 180, ensuring that the humidity and oxygen content within the cooking cavity 1102 meet cooking requirements. This resolves the technical shortcomings of the related art and further achieves the technical effect of optimizing the structure of the air fryer 100, improving the practicality and controllability of the air fryer 100, enhancing the quality of the cooked food, and improving the user experience.

[0186] Specifically, the air duct 121 speeds up the speed at which outside air enters the cooking cavity 1102, improves the efficiency of outside air participation in the cooking cavity 1102, increases the aldehyde substances that characterize the aroma of food, enhances the aroma of food, and reduces the amount of harmful substances such as acrylamide or heterocyclic amines generated during the cooking process.

[0187] As shown in Figures 21 and 22, in some embodiments of the present application, optionally, the liquid delivery component 180 also includes: a water tank 186, which is used to store liquid; a water supply component 188, which connects the water tank 186 and the atomizer 182, and the water supply component 188 is used to deliver liquid to the atomizer 182.

[0188] In this embodiment, the liquid delivery assembly 180 further includes a water tank 186 and a water supply component 188. The water tank 186 is connected to the body 110 and is used to store liquid. The water supply component 188 connects the water tank 186 and the atomizer 182. The water supply component 188 can deliver the liquid in the water tank 186 to the atomizer 182 to meet the water supply demand of the atomizer 182.

[0189] It can be seen that by providing the water tank 186 and the water supply component 188, the automatic water supply of the atomizer 182 can be achieved, so that the atomizer 182 can continuously produce water mist to the air duct 121 through the liquid transported by the water supply component 188, thereby achieving the technical effect of improving the degree of automation of the air fryer 100 and improving the practicality of the air fryer 100.

[0190] As shown in Figures 20, 21 and 22, in some embodiments of the present application, optionally, the conveying component includes: an atomizer 182, the atomizer 182 is used to generate water mist; an atomizing tube 184, the first end of the atomizing tube 184 is connected to the atomizer 182, and the second end of the atomizing tube 184 is connected to the air duct 121.

[0191] In this embodiment, the conveying component is capable of conveying water mist into the air duct 121 .

[0192] On this basis, the conveying component includes an atomizer 182 and an atomizing tube 184. The atomizer 182 can turn moisture into tiny water mist molecules through high-frequency vibration. The first end of the atomizing tube 184 is connected to the output end of the atomizer 182, and the second end of the atomizing tube 184 is connected to the air duct 121. After the atomizer 182 is powered on, the atomizing tube 184 can convey the water mist produced by the atomizer 182 into the air duct 121.

[0193] Among them, there is an externally introduced air flow in the air duct 121 flowing to the cooking cavity 1102. After the water mist is discharged into the air duct 121 through the atomizing tube 184, it is driven by the externally introduced air flow to flow toward the cooking cavity 1102, thereby simultaneously transporting the externally introduced air flow and water mist into the cooking cavity 1102. The externally introduced air flow can increase the oxygen content in the cooking cavity 1102 and reduce the temperature in the cooking cavity 1102. On the one hand, the water mist can increase the humidity in the cooking cavity 1102, and on the other hand, it can directly moisten the food in the cooking cavity 1102, thereby ensuring that the environment in the cooking cavity 1102 meets the cooking requirements, thereby achieving the technical effect of improving the quality of the cooked food.

[0194] In some embodiments of the present application, optionally, the water vapor includes steam, and the conveying component includes: a steam generator, the steam generator is connected to the air duct 121, and the steam generator is used to generate steam.

[0195] In this embodiment, the conveying component is capable of conveying steam into the air duct 121 .

[0196] On this basis, the delivery component includes a steam generator, which is connected to the water supply component 188. The water supply component 188 is used to supply water to the steam generator. During operation, the steam generator can heat the liquid delivered by the water supply component 188 into steam and deliver the heated steam to the air duct 121.

[0197] Among them, there is an externally introduced air flow in the air duct 121 flowing to the cooking cavity 1102. After the steam is discharged into the air duct 121 through the atomization tube, it is driven by the externally introduced air flow to flow toward the cooking cavity 1102, thereby simultaneously transporting the externally introduced air flow and steam into the cooking cavity 1102. The externally introduced air flow can increase the oxygen content in the cooking cavity 1102 and reduce the temperature in the cooking cavity 1102. On the one hand, the steam can increase the humidity in the cooking cavity 1102, and on the other hand, it can directly moisten the food in the cooking cavity 1102, thereby ensuring that the environment in the cooking cavity 1102 meets the cooking requirements, thereby achieving the technical effect of improving the quality of the cooked food.

[0198] As shown in Figure 21, in some embodiments of the present application, optionally, the water supply component 188 includes: a first capillary structure 1882, the first end of the first capillary structure 1882 is connected to the delivery component, the second end of the first capillary structure 1882 is configured to contact the liquid in the water tank 186, and the first capillary structure 1882 is used to deliver liquid to the atomizer 182 through capillary phenomenon; wherein, the first capillary structure 1882 includes a cotton strip and / or a capillary tube.

[0199] In this embodiment, the water supply component 188 includes a first capillary structure 1882 , a first end of which is connected to the atomizer 182 or the steam generator, and a second end of which is inserted into the water tank 186 and keeps contact with the liquid in the water tank 186 .

[0200] During operation, the first capillary structure 1882 can slowly and continuously transport the liquid in the water tank 186 to the atomizer 182 or the steam generator through capillary phenomenon, so that the atomizer 182 can continuously produce water mist into the air duct 121, or the steam generator can continuously produce steam into the air duct 121.

[0201] Compared with the active water supply solution, the first capillary structure 1882 has the advantages of low complexity and low failure rate, and setting the first capillary structure 1882 to supply water to the conveying component is conducive to reducing the cost of the air fryer 100, thereby improving the market competitiveness of the air fryer 100.

[0202] Specifically, the first capillary structure 1882 includes a tampon and / or a capillary tube. The tampon can generate a capillary phenomenon through tiny pores inside the tampon, and the capillary tube can achieve a capillary phenomenon through a narrow and long passage inside the capillary tube.

[0203] As shown in FIG. 22 , in some embodiments of the present application, optionally, the water supply component 188 includes: a water supply pipe 1884 , connecting the water tank 186 and the conveying component; and a pump body 1886 , provided on the water supply pipe 1884 .

[0204] In this embodiment, the water supply component 188 includes a water supply pipe 1884 and a pump body 1886. One end of the water supply pipe 1884 is connected to the water tank 186, and the second end of the water supply pipe 1884 is connected to the atomizer 182 or the steam generator. The pump body 1886 is arranged on the water supply pipe 1884. The pump body 1886 is used to drive the liquid in the water supply pipe 1884 to flow toward the atomizer 182 or the steam generator, thereby realizing automatic water supply to the atomizer 182 or the steam generator.

[0205] Compared with the passive water supply solution, the pump body 1886 can turn on and off the delivery components by switching the start and stop states. The pump body 1886 can also adjust the water vapor production rate by controlling the opening, thereby achieving the technical effect of improving the controllability of the water vapor production process and improving the degree of automation of the air fryer 100.

[0206] As shown in Figures 21 and 22, in some embodiments of the present application, optionally, the water tank 186 includes a first cavity 1862 and a second cavity 1864, and the first cavity 1862 and the second cavity 1864 are connected; the atomizer 182 and the water supply component 188 are arranged in the first cavity 1862, and the first end of the atomizing tube 184 is connected to the first cavity 1862.

[0207] In this embodiment, a first cavity 1862 and a second cavity 1864 are provided in the water tank 186, and the bottoms of the first cavity 1862 and the second cavity 1864 are connected by a through hole, wherein the first cavity 1862 is used to accommodate the atomizer 182 and the water supply component 188, water mist is generated in the first cavity 1862, and the atomizing tube 184 is connected to the first cavity 1862, and the produced water mist enters the atomizing tube 184 from the first cavity 1862.

[0208] The second cavity 1864 is used to store liquid. When the first capillary structure 1882 is used to supply water to the atomizer 182, the second end of the first capillary structure 1882 is close to the bottom wall of the first cavity 1862. After the liquid enters the first cavity 1862 under the connection effect, it can contact the first capillary structure 1882 and be transferred upward to the atomizer 182 through capillary action.

[0209] When water is supplied by the water supply pipe 1884 and the water pump, the first end of the water supply pipe 1884 is connected to the through hole between the first cavity 1862 and the second cavity 1864 , and the pump body 1886 draws the liquid in the second cavity 1864 into the atomizer 182 through the water supply pipe 1884 .

[0210] By arranging the atomizer 182 and the water supply component 188 in the water tank 186, a hidden design of the atomizer 182 and the water supply component 188 can be achieved. On the one hand, the exposed atomizer 182 and the water supply component 188 are avoided from causing an abrupt feeling. On the other hand, the atomizer 182 and the water supply component 188 are protected by the water tank 186, thereby achieving the technical effect of optimizing the structure of the liquid delivery component 180, improving the reliability of the liquid delivery component 180, and reducing the failure rate of the liquid delivery component 180.

[0211] As shown in FIG. 20 , FIG. 21 and FIG. 22 , in some embodiments of the present application, optionally, the water tank 186 further includes an air inlet 1866 , which is located on the periphery of the water tank 186 and communicates with the first cavity 1862 ;

[0212] In this embodiment, an air inlet 1866 is also provided on the water tank 186, which connects the first cavity 1862 and the external space. The air inlet 1866 can introduce external air into the first cavity 1862. The atomizer 182 converts the liquid into fine water mist molecules through high-frequency vibration and mixes it with the air to form water mist.

[0213] Specifically, the air inlet 1866 is provided on the peripheral side of the water tank 186 , and there are multiple air inlets 1866 , which are evenly distributed to ensure that the first cavity 1862 where the atomizer 182 is located is in communication with the atmosphere.

[0214] As shown in FIG. 20 , in some embodiments of the present application, optionally, the water tank 186 further includes a water inlet 1868 , which is located at the top of the water tank 186 , and is connected to the second cavity 1864 .

[0215] In this embodiment, the water tank 186 further includes a water inlet 1868 , which is disposed at the top of the water tank 186 and communicates with the second cavity 1864 . The second cavity 1864 can be replenished with liquid through the water inlet 1868 .

[0216] Specifically, the water inlet 1868 can be connected to an external water source through a water pipe to achieve automatic water replenishment of the water tank 186 . The user can also achieve active water replenishment of the water tank 186 by pouring liquid into the water inlet 1868 .

[0217] As shown in Figure 23, in some embodiments of the present application, optionally, the air duct 121 includes a first air duct 1202 and a second air duct 1204, the first end and the second end of the second air duct 1204 are both connected to the cooking cavity 1102, the first end of the first air duct 1202 is connected to the second air duct 1204, and the second end of the first air duct 1202 is connected to the outside of the main body 110; the liquid delivery component 180 is connected to the first air duct 1202 and / or the second air duct 1204.

[0218] In FIG23 , arrow a shows the air flow introduced from the outside, and arrow b shows the internal circulating air flow. The air flow introduced from the outside and the water mist are mixed in the area pointed by arrow d.

[0219] The liquid delivery assembly 180 is in communication with at least one of the first air duct 1202 and the second air duct 1204 via a water supply component, thereby delivering water vapor to the first air duct 1202 and / or the second air duct 1204 .

[0220] Specifically, the air induced component 120 includes: a first pipe, which is arranged in the main body 110, and the first pipe encloses a first air duct 1202; the first end of the first pipe is connected to the space outside the main body 110; a second pipe, which is arranged in the cooking cavity 1102 and is connected to the first pipe, and the second pipe encloses a second air duct 1204.

[0221] In this embodiment, the structure of the air induction assembly 120 is defined. Specifically, the air induction assembly 120 includes a first duct connected to the main body 110. An external air inlet is defined on the inner wall of the cooking cavity 1102. When the second air duct 1204 is tightly attached to the inner wall of the cooking cavity 1102, the first end of the first duct abuts against the external air inlet. Specifically, an annular boss can be provided on the first end of the first duct to abut against the outer wall of the cooking cavity 1102.

[0222] When the second air duct 1204 is away from the inner wall of the cooking cavity 1102, the first end of the first air duct 1202 is inserted into the cooking cavity 1102 through the external air inlet and communicates with the second air duct 1204 in the cooking cavity 1102. In this case, the external air inlet can position the first duct, preventing the first duct from becoming loose, misaligned, or even falling off.

[0223] Specifically, the first pipe is arranged at the top of the cooking cavity 1102 , and the first pipe extends from top to bottom. Air flow introduced from the outside is poured into the cooking cavity 1102 along the first pipe extending longitudinally.

[0224] Air induction assembly 120 also includes a second duct, which is disposed within cooking cavity 1102 and spaced apart from the inner wall of cooking cavity 1102. The first end of the first duct extends from an external air inlet into cooking cavity 1102 and communicates with the middle section of the second duct. The first duct provides positioning and support for the second duct, and a bracket connecting the inner wall of cooking cavity 1102 and the second duct can be provided to position and support the second duct.

[0225] As shown in Figures 20 and 23, in some embodiments of the present application, optionally, the air fryer 100 also includes: an inner pot 130, which is arranged in the cooking cavity 1102, and the inner pot 130 includes a accommodating cavity and an opening; a motor 142, which is connected to the body 110; and fan blades 144, which are connected to the motor 142, and the motor 142 is used to drive the fan blades 144 to rotate and form an internal circulating airflow.

[0226] As shown in Figure 27, in some technical solutions of the present application, optionally, the air fryer 100 also includes: a temperature control valve, which is arranged in the air induced component 120, and the temperature control valve can operate according to the temperature in the cooking cavity 1102 and / or the air duct 121, and adjust the flow of the air duct 121 through the action.

[0227] In FIG27 , arrow a shows the flow direction of the air flow introduced from the outside, arrow b shows the flow direction of the internal circulation air flow, and arrow d shows the outflow direction of the air flow introduced from the outside and the internal circulation air flow.

[0228] The air fryer 100 also includes a temperature control valve, which is connected to the air induced component 120. The temperature control valve can perform an action according to the temperature of the cooking cavity 1102 and / or perform an action according to the temperature in the air duct 121 to adjust the flow of the air duct 121 through the action. Specifically, the temperature control valve can control the switching state of the air duct 121 corresponding to the temperature value.

[0229] Specifically, when the air fryer 100 is in standby mode or in the initial stage of the cooking process, the temperature in the cooking cavity 1102 and / or the flow channel is relatively low, and the temperature control valve remains closed within the relatively low temperature range. At this time, the cooking cavity 1102 cannot introduce external airflow and moisture via the draft assembly 120. During the cooking process, the temperature and humidity in the cooking cavity 1102 and / or the flow channel gradually increase, while the oxygen content gradually decreases. When the temperature rises to a higher temperature range, the humidity in the cooking cavity 1102 is correspondingly within the higher humidity range, and the oxygen content is relatively low. At this point, the temperature control valve can operate in response to the rising temperature, thereby opening the flow channel, allowing the cooking cavity 1102 to introduce external airflow via the draft assembly 120, thereby timely adjusting the temperature, humidity, and oxygen content within the cooking cavity 1102.

[0230] At the same time, the temperature control valve can not only control the opening and closing of the air duct 121, but also control the opening degree of the air duct 121, so as to accurately control the flow rate of the fresh air flow during the process of introducing external fresh air flow.

[0231] It can be seen that by setting the temperature control valve, the air fryer 100 can control the timing of introducing external airflow through the temperature control valve, on the one hand, ensuring that the humidity value, oxygen content and other parameters in the cooking cavity 1102 can meet the cooking requirements, and on the other hand, preventing dust and mosquitoes from entering the cooking cavity 1102 through the air duct 121 when the air fryer 100 is on standby, thereby optimizing the structure of the air fryer 100, improving the practicality and controllability of the air fryer 100, improving the quality of cooked food, and enhancing the user experience.

[0232] As shown in Figures 20, 25 and 26, in some technical solutions of the present application, optionally, the main body 110 also includes a heat dissipation cavity 1105, and the air fryer 100 also includes: a hot air component 141, which is provided on the main body 110, and the hot air component 141 is used to blow high-temperature airflow to the cooking cavity 1102, and the heat dissipation cavity 1105 is used to export the heat of the hot air component 141 to the outside of the main body 110; the air duct 121 connects the space outside the main body 110, the cooking cavity 1102 and the heat dissipation cavity 1105, or the air duct 121 connects the space outside the main body 110 and the heat dissipation cavity 1105.

[0233] In FIG. 25 and FIG. 26 , arrow a shows the flow direction of the air flow introduced from the outside.

[0234] The air fryer 100 also includes a hot air component 141, which is installed in the body 110 and is at least partially located outside the cooking cavity 1102. The hot air component 141 can blow high-temperature air into the cooking cavity 1102. The surface of the food is rapidly heated after contacting the high-temperature air flow, forming a crispy and golden shell on the outside of the food, thereby improving the taste and quality of the food.

[0235] A heat dissipation cavity 1105 is also formed within the body 110. This cavity 1105 is positioned opposite the hot air assembly 141 and has an outlet. This outlet connects the heat dissipation cavity 1105 to the exterior of the body 110. During cooking, the heat dissipation cavity 1105 directs the heat generated by the hot air assembly 141 to the exterior of the body 110 via airflow, providing continuous heat dissipation for the hot air assembly 141. This keeps the hot air assembly 141 within a safe temperature range and prevents overheating and damage.

[0236] However, because the airflow discharged from the heat dissipation cavity 1105 carries a large amount of heat, the temperature of the gas discharged from the outlet is too high. When the user operates the air fryer 100, the user may be easily scalded by the high-temperature gas discharged from the heat dissipation cavity 1105, resulting in a safety hazard for the air fryer 100.

[0237] In this regard, the air fryer 100 is further provided with an air induced component 120, which connects the space outside the body 110, the cooking cavity 1102 and the heat dissipation cavity 1105, or connects the space outside the body 110 and the heat dissipation cavity 1105.

[0238] During operation, the gas flowing within the heat dissipation cavity 1105 forms a heat dissipation airflow within the heat dissipation cavity 1105. Due to the characteristics of the fluid medium, the pressure in areas with high flow velocity during the flow of the fluid medium is relatively low. Due to the presence of the heat dissipation airflow, the pressure within the heat dissipation cavity 1105 is relatively low compared to the pressure of the environment outside the body 110. Under the action of the pressure difference, the external gas is pressed into the air duct 121, forming an external air flow within the air duct 121. The external air flow flows from the air duct 121 to the heat dissipation cavity 1105. After entering the heat dissipation cavity 1105, the external air flow merges with the heat dissipation airflow, allowing the heat dissipation cavity 1105 to continuously introduce external air during operation, thereby using the external air to reduce the temperature of the heat dissipation airflow discharged from the heat dissipation cavity 1105, thereby preventing users from being scalded by the heat dissipation airflow discharged from the heat dissipation cavity 1105. This eliminates the safety hazard of the air fryer 100 easily scalding the user, achieving the technical effect of optimizing the structure of the air fryer 100 and improving the safety and reliability of the air fryer 100.

[0239] On this basis, the gas flowing within cooking cavity 1102 forms an internal circulating airflow within cooking cavity 1102. Due to the characteristics of a fluid medium, areas with high flow rates experience lower pressure. Due to the internal circulating airflow, the pressure within cooking cavity 1102 is lower than the pressure outside body 110. Due to this pressure differential, external gas, carrying moisture output by induced draft assembly 120, is forced into air duct 121, forming an external airflow within air duct 121. This external airflow flows from air duct 121 into cooking cavity 1102, where it merges with the internal circulating airflow. This allows cooking cavity 1102 to continuously draw in external air and moisture during operation. This external airflow is used to adjust cooking parameters such as humidity and oxygen content within cooking cavity 1102 to meet the cooking requirements of specific foods. This optimizes the structure of air fryer 100, improves the quality of cooked food, and enhances the user experience.

[0240] In some technical solutions of the present application, optionally, the liquid delivery component 130 includes: a second capillary structure, the first end of the second capillary structure is located in the air duct 121, the second end of the second capillary structure is configured to contact the liquid in the water tank 186, and the second capillary structure is used to deliver water vapor to the air duct 121 through capillary phenomenon.

[0241] In this technical solution, the water supply component 188 includes a second capillary structure, a first end of the second capillary structure is arranged in the air duct 121 , and a second end of the second capillary structure is inserted into the water tank 186 and keeps contact with the liquid in the water tank 186 .

[0242] During operation, the second capillary structure can slowly and continuously transport the liquid in the water tank 186 to the air duct 121 through the capillary phenomenon, so as to form a continuous flow of water vapor in the air duct 121.

[0243] Compared with the active water supply solution, the second capillary structure has the advantages of low complexity and low failure rate. Setting the second capillary structure to provide water vapor for the air duct 121 is beneficial to reducing the cost of the air fryer 100, thereby improving the market competitiveness of the air fryer 100.

[0244] Specifically, the second capillary structure includes a tampon and / or a capillary tube. The tampon can generate capillary phenomenon through tiny pores inside the tampon, and the capillary tube can achieve capillary phenomenon through a narrow and long passage inside the capillary tube.
