Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, and in particular to an air fryer. Background Art

[0002] The hot air mechanism in the air fryer will generate a lot of heat during the cooking process. If this heat is not discharged in time, the air fryer may overheat and be damaged.

[0003] In related technologies, the heat generated by the hot air mechanism is mostly discharged to the outside of the air fryer through a heat dissipation cavity. However, the temperature of the air flow discharged from the heat dissipation cavity is relatively high, which can easily burn the user, resulting in technical problems of poor safety and reliability of the air fryer.

[0004] Therefore, how to overcome the above-mentioned technical defects has become a technical problem that needs to be solved urgently. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0006] Therefore, the utility model proposes an air fryer.

[0007] In view of this, the air fryer provided by the present invention includes: a main body, which includes a cooking cavity and a heat dissipation cavity, and the heat dissipation cavity is connected to the space outside the main body; a hot air component, which is provided in the main body, and the hot air component is used to blow high-temperature airflow into the cooking cavity, and the heat dissipation cavity is used to conduct heat of the hot air component to the outside of the main body; an air induced component, which is provided in the main body, and the air induced component includes an air duct, at least part of which is connected to the space outside the main body and the heat dissipation cavity.

[0008] 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.

[0009] The air fryer also includes a hot air component, which is installed in the main body and is at least partially located outside the cooking cavity. The hot air component can blow high-temperature air into the cooking cavity. 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.

[0010] The main body also includes a heat dissipation cavity, located opposite the hot air assembly. An outlet is provided on the main body, connecting the heat dissipation cavity to the exterior of the main body. During cooking, the heat dissipation cavity directs heat generated by the hot air assembly to the exterior of the main body through airflow, providing continuous heat dissipation for the hot air assembly, keeping it within a safe temperature range and preventing overheating and damage.

[0011] However, because the airflow discharged from the heat dissipation chamber carries a large amount of heat, the temperature of the gas discharged from the outlet is too high. When users operate the air fryer, they are easily scalded by the high-temperature gas discharged from the heat dissipation chamber, which poses a safety hazard to the air fryer.

[0012] In this regard, the air fryer is further provided with an air induction component, which includes an air duct, at least a part of which is connected to the space outside the body and the heat dissipation cavity.

[0013] During operation, the gas flowing in the heat dissipation cavity forms a heat dissipation airflow in the heat dissipation cavity. Based on the characteristics of the fluid medium, during the flow of the fluid medium, the pressure in the area with a high flow rate is relatively low. Due to the existence of the heat dissipation airflow, the pressure in the heat dissipation cavity is relatively low compared to the pressure of the external environment of the body. Under the action of the pressure difference, the external gas is pressed into the air duct, and an external air flow is formed in the air duct. The external air flow flows from the air duct to the heat dissipation cavity, and the external air flow enters the heat dissipation cavity and merges into the heat dissipation airflow, so that the heat dissipation cavity can 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 to avoid users being scalded by the heat dissipation airflow discharged from the heat dissipation cavity, thereby eliminating the safety hazard of air fryers easily scalding users and solving the technical problems existing in related technologies. This achieves the technical effect of optimizing the structure of the air fryer and improving the safety and reliability of the air fryer.

[0014] In addition, the air fryer provided by the present invention may also have the following additional technical features:

[0015] In some technical solutions of the present invention, specifically, the air duct only connects the space outside the body and the heat dissipation cavity.

[0016] In this technical solution, the air duct only connects the space outside the main body and the heat dissipation cavity, and is not connected to the cooking cavity. In this case, the air duct can pressurize external gas into the air duct under the action of the pressure difference, specifically forming an external air flow in the air duct, which flows from the air duct to the heat dissipation cavity. After entering the heat dissipation cavity, the external air flow merges into the heat dissipation air flow, allowing the heat dissipation cavity to continuously introduce external air during operation, thereby using the external air to reduce the temperature of the heat dissipation air flow discharged from the heat dissipation cavity to prevent users from being scalded by the heat dissipation air flow discharged from the heat dissipation cavity, thereby eliminating the safety hazard of air fryers easily scalding users and solving the technical problems existing in related technologies. This achieves the technical effect of optimizing the structure of the air fryer and improving the safety and reliability of the air fryer.

[0017] In some technical solutions of the present invention, specifically, at least part of the air duct is connected to the space outside the body and the heat dissipation cavity, and at least part of the air duct is connected to the space outside the body and the cooking cavity.

[0018] In this technical solution, a part of the air duct is connected to the space outside the body and the heat dissipation cavity, and another part of the air duct is connected to the space outside the body and the cooking cavity.

[0019] On this basis, the gas flowing in the cooking cavity forms an internal circulation airflow in the cooking cavity. Based on the characteristics of the fluid medium, during the flow of the fluid medium, the pressure in the area with a high flow rate is relatively low. Due to the existence of the internal circulation airflow, the pressure in the cooking cavity is lower than the pressure of the external environment of the body. Under the action of the pressure difference, the external gas is pressed into the air duct, and an external air flow is formed in the air duct. The external air flow flows from the air duct to the cooking cavity, and the external air flow enters the cooking cavity and merges into the internal circulation airflow, so that the cooking cavity can continuously introduce external air during operation. Therefore, the humidity, oxygen content and other cooking parameters in the cooking cavity are adjusted with the help of external air to meet the cooking requirements of specific foods. This thereby achieves the technical effect of optimizing the structure of the air fryer, improving the quality of the cooked food, and enhancing the user experience.

[0020] In some technical solutions of the present invention, specifically, the air duct includes: a first air duct, the first end of the first air duct is connected to the space outside the main body, and the second end of the first air duct is connected to the cooking cavity; a second air duct, the first end of the second air duct is connected to the first air duct, and the second end of the second air duct is connected to the heat dissipation cavity.

[0021] In this technical solution, the air duct includes a first air duct and a second air duct. The first end of the first air duct communicates with the space outside the main body, and the second end of the first air duct communicates with the cooking cavity. Air flow from the outside can flow into the cooking cavity through the first air duct to adjust the temperature, humidity, and oxygen content within the cooking cavity. The second air duct is connected to the first air duct in parallel, with the first end of the second air duct communicating with the first air duct, and the second end of the second air duct communicating with the heat dissipation cavity. The air flow from the outside that flows in through the first end of the first air duct is split at the intersection of the first and second air ducts, with one portion flowing into the cooking cavity and the other portion flowing into the heat dissipation cavity. This reduces the temperature of the heat dissipation airflow within the heat dissipation cavity while meeting the requirements for regulating the environmental parameters within the cooking cavity, thereby achieving a balanced practicality and safety of the air fryer.

[0022] By setting up a second air duct connected to the first air duct, the structural complexity of the air duct can be reduced. On the one hand, the cost of the air induced component can be reduced, and on the other hand, convenient conditions can be provided for the miniaturization and lightweight design of the air fryer.

[0023] In some technical solutions of the present invention, specifically, the air duct also includes: a third air duct, the third air duct is located in the cooking cavity, the first end and the second end of the third air duct are both connected to the cooking cavity, and the second end of the first air duct is connected to the third air duct.

[0024] In this technical solution, the air duct also includes a third air duct, the first end of which communicates with the cooking cavity, and the second end of which also communicates with the cooking cavity. The second end of the first air duct communicates with the middle section of the third air duct, and the first end of the first air duct extends toward the outer surface of the main body and ultimately communicates with the space outside the main body. In other words, the third air duct connects two different areas within the cooking cavity, while the first air duct connects the cooking cavity and the exterior of the air fryer.

[0025] During operation, gas flowing within the cooking cavity flows into the third duct from one of its first and second ends and ultimately flows out of the third duct from the other end, forming an internal circulation airflow within the third duct. Due to the characteristics of the fluid medium, during flow, the pressure in areas with high flow velocity is lower. Due to the presence of the internal circulation airflow, the pressure within the second duct is lower than the pressure of the environment outside the main body. Due to the pressure difference, external gas is forced into the first duct, forming an external airflow within the first duct. The external airflow flows from the second end of the first duct to the first end of the first duct. After entering the third duct, the external airflow merges with the internal circulation airflow and ultimately flows into the cooking cavity, allowing the cooking cavity 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 the cooking cavity to meet the cooking requirements of specific foods.

[0026] Compared with the solution in which the second end of the first air duct is directly connected to the cooking cavity, the internal circulating airflow can be accelerated inside the third air duct, thereby increasing the pressure difference between the third air duct and the external environment, so as to increase the introduction rate of the air flow introduced from the outside, and thereby improve the regulation effect of the temperature, humidity and oxygen content in the cooking cavity.

[0027] In some technical solutions of the present invention, specifically, the flow area of ​​the second end of the first air duct is larger than the flow area of ​​the first end of the third air duct, and / or the flow area of ​​the second end of the first air duct is larger than the flow area of ​​the second end of the third air duct.

[0028] In this technical solution, the flow area of ​​the second end of the first air duct is the third area, and the flow area of ​​the first end and / or the second end of the third air duct is the fourth area, wherein the third area is smaller than the fourth area.

[0029] By limiting the size relationship between the third area and the fourth area, the air flow introduced from the outside can accelerate the internal circulation air flow in the third air duct when it merges into the third air duct, so as to increase the circulation rate of the internal circulation air flow and the merging rate of the air flow introduced from the outside, thereby improving the regulating effect of the air flow introduced from the outside on the temperature, humidity and oxygen content in the cooking cavity.

[0030] In some technical solutions of the present invention, specifically, the main body also includes a heat dissipation channel, the heat dissipation channel is at least partially located in the heat dissipation cavity, and a heat dissipation fan is provided in the heat dissipation cavity; the heat dissipation channel includes an inlet and an outlet, both the inlet and the outlet are connected to the heat dissipation cavity, and the air duct is connected to the heat dissipation channel.

[0031] In this technical solution, a heat dissipation channel is also provided in the main body, and the heat dissipation channel is at least partially located in the heat dissipation cavity. The inlet and outlet of the heat dissipation channel are connected to the heat dissipation cavity, and the air duct is connected to the heat dissipation channel. The air flow introduced from the outside can be merged into the heat dissipation channel under the action of the pressure difference.

[0032] On this basis, a cooling fan is provided in the heat dissipation cavity. The rotating cooling fan can drive the gas flow in the heat dissipation cavity, thereby increasing the flow rate of the heat dissipation airflow. The high-speed heat dissipation airflow enters the heat dissipation channel from the inlet and flows out of the heat dissipation channel from the outlet.

[0033] By increasing the air flow rate within the heat dissipation channel using a cooling fan, the pressure difference between the space outside the main body and the heat dissipation channel can be increased, thereby increasing the introduction rate of external air flow, and further enhancing the heat dissipation effect of the external air flow on the heat dissipation cavity, thereby preventing users from being burned by the heat dissipation airflow discharged from the heat dissipation cavity. This eliminates the safety hazard of air fryers easily burning users and solves the technical problems existing in related technologies. This further achieves the technical effect of optimizing the air fryer structure and improving the safety and reliability of the air fryer.

[0034] During operation, the heat generated by the hot air assembly first diffuses into the heat dissipation cavity, then flows along with the heat dissipation airflow into the heat dissipation channel, ultimately channeling it out of the main body. This heat dissipation channel allows for concentrated heat dissipation within the heat dissipation cavity, reducing the high-temperature area on the main body's housing while also increasing the rate of heat dissipation through the smaller heat dissipation channels.

[0035] On this basis, the second end of the second air duct is connected to the heat dissipation channel, or the second end of the fourth air duct is connected to the heat dissipation channel. The heat dissipation airflow will continue to absorb heat while flowing in the heat dissipation cavity. If the second end of the second air duct or the second end of the fourth air duct is connected to the heat dissipation cavity outside the heat dissipation channel, the airflow introduced from the outside will also absorb heat and heat up before entering the heat dissipation channel, resulting in the cooling effect of the airflow introduced from the outside on the heat dissipation airflow that is finally discharged being affected. In this regard, by connecting the second end of the second air duct or the second end of the fourth air duct to the heat dissipation channel, the airflow introduced from the outside can be merged into the heat dissipation airflow just before the heat dissipation airflow is about to be discharged from the main body, thereby enhancing the cooling effect of the airflow introduced from the outside on the heat dissipation airflow and reducing the temperature of the heat dissipation airflow discharged from the outlet, thereby achieving the technical effect of optimizing the structure of the air induction component and improving the safety of the air fryer.

[0036] In some technical solutions of the present invention, specifically, the flow area of ​​the communicating end between the air duct and the heat dissipation channel is smaller than the flow area of ​​the inlet.

[0037] In this technical solution, the flow area of ​​the second end of the second air duct is the first area, or the flow area of ​​the second end of the fourth air duct is the first area, and the flow area of ​​the inlet of the heat dissipation channel is the second area, wherein the first area is smaller than the second area.

[0038] By limiting the size relationship between the first area and the second area, the air flow introduced from the outside can accelerate the heat dissipation airflow in the heat dissipation channel when it merges into the heat dissipation channel, so as to increase the discharge rate of the heat dissipation airflow, thereby improving the heat dissipation effect of the heat dissipation cavity and the heat dissipation duct on the hot air component on the one hand, and reducing the temperature of the discharged heat dissipation airflow on the other hand, thereby achieving the technical effect of improving the safety and reliability of the air fryer.

[0039] In some technical solutions of the present invention, specifically, the heat dissipation fan includes an air outlet side and an air return side; the inlet of the heat dissipation channel is located on the air outlet side of the heat dissipation fan, and the extension direction of the heat dissipation channel is consistent with the air outlet direction of the heat dissipation fan.

[0040] In this technical solution, the heat dissipation fan includes an air outlet side and an air return side. The heat dissipation fan can be a centrifugal fan. The air outlet side is located on the peripheral side of the centrifugal fan, and the return side is located on the side facing the centrifugal fan.

[0041] The inlet of the heat dissipation channel is arranged on the peripheral side of the centrifugal fan, so that the heat dissipation airflow blown by the centrifugal fan can smoothly enter the heat dissipation channel, ensuring a sufficiently large pressure difference between the heat dissipation channel and the external space of the body.

[0042] On this basis, the heat dissipation channel extends around the centrifugal fan along the circumferential direction of the centrifugal fan. By extending the heat dissipation channel along the circumference of the centrifugal fan, the extension direction of the heat dissipation channel can be made consistent with the flow direction of the heat dissipation airflow blown out by the centrifugal fan, thereby reducing the resistance of the heat dissipation channel to the heat dissipation airflow, increasing the gas flow rate in the heat dissipation channel, and then increasing the introduction rate of air flow introduced from the outside by increasing the pressure difference between the heat dissipation channel and the external space of the main body.

[0043] Correspondingly, the heat dissipation fan may also be an axial flow fan, with the air outlet side located on the side facing the axial flow fan and the air return side located on the side facing away from the axial flow fan.

[0044] The inlet of the heat dissipation channel is arranged on the side facing the axial flow fan, so that the heat dissipation airflow blown by the axial flow fan can smoothly enter the heat dissipation channel, ensuring a sufficiently large pressure difference between the heat dissipation channel and the external space of the body.

[0045] On this basis, the heat dissipation channel extends along the axial direction of the axial fan on the side facing the axial fan, so that the extension direction of the heat dissipation channel is consistent with the flow direction of the heat dissipation airflow blown out by the axial fan, thereby reducing the resistance of the heat dissipation channel to the heat dissipation airflow, increasing the gas flow rate in the heat dissipation channel, and then increasing the introduction rate of air flow introduced from the outside by increasing the pressure difference between the heat dissipation channel and the external space of the main body.

[0046] In some technical solutions of the present invention, specifically, the air induced component also includes: a fan, located on the side of the air duct facing the outside of the air fryer, and the airflow of the air duct can drive the fan to rotate; a cover body, arranged opposite to the fan, and the cover body is a light-transmitting cover.

[0047] In this technical solution, the air flow introduced from the outside that is pressed in by the pressure difference between the inside and the outside can drive the fan to rotate. The faster the flow rate of the air flow introduced from the outside, the faster the rotation speed of the fan. The user can observe the status of the internal fan through the air inlet on the cover. Afterwards, the air flow introduced from the outside enters the cooking cavity through the through hole, the first air duct and the second air duct to meet the air supply demand of the cooking cavity, or the air flow introduced from the outside enters the heat dissipation cavity through the fourth air duct.

[0048] By setting up an observable fan, the externalization effect of the incoming air flow can be achieved, so that the user can judge whether there is an air flow introduced from the outside by observing whether the fan is rotating, and judge the intensity of the air flow introduced from the outside by observing the speed of the fan, providing convenient conditions for the user to control the air fryer.

[0049] In addition, users can also judge the flow rate of air introduced from the outside by the fan speed, and further adjust the flow rate or flow rate through the temperature control valve according to personal needs to obtain a better cooking experience.

[0050] By providing a light-transmitting cover, the user can observe the status of the fan inside the cover through the cover, thereby improving the externalization effect of the fan on the air flow introduced from the outside and reducing the difficulty for the user to observe the fan.

[0051] Specifically, the cover can be made of materials such as glass and plastic.

DETAILED DESCRIPTION

[0061] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0062] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0063] Refer to the following Figures 1 to 5 An air fryer according to some embodiments of the present invention is described.

[0064] like Figure 1 and Figure 2As shown, one embodiment of the present invention provides an air fryer 100, which includes: a main body 110, including a cooking cavity 1102 and a heat dissipation cavity 1104, and the heat dissipation cavity 1104 is connected to the space outside the main body 110; a hot air component 130, which is provided on the main body 110, and the hot air component 130 is used to blow high-temperature air flow into the cooking cavity 1102, and the heat dissipation cavity 1104 is used to export the heat of the hot air component 130 to the outside of the main body 110; an air induced component 120, which is provided on the main body 110, and the air induced component 120 includes an air duct 122, and at least part of the air duct 122 is connected to the space outside the main body 110 and the heat dissipation cavity 1104.

[0065] The present application defines an air fryer 100, which includes a body 110. The body 110 is a frame structure of the air fryer 100, which 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, and food is placed in the cooking cavity 1102 and processed into finished food.

[0066] The air fryer 100 also includes a hot air component 130, which is installed in the body 110 and is at least partially located outside the cooking cavity 1102. The hot air component 130 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.

[0067] A heat dissipation cavity 1104 is also formed within the body 110. This cavity 1104 is positioned opposite the hot air assembly 130 and has an outlet. This outlet connects the heat dissipation cavity 1104 to the space outside the body 110. During cooking, the heat dissipation cavity 1104 directs the heat generated by the hot air assembly 130 to the exterior of the body 110 via airflow, providing continuous heat dissipation for the hot air assembly 130, keeping it within a safe temperature range and preventing overheating and damage.

[0068] However, because the airflow discharged from the heat dissipation cavity 1104 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 1104, resulting in a safety hazard for the air fryer 100.

[0069] In this regard, the air fryer 100 is further provided with an air induction component 120 , which includes an air duct 122 , at least a portion of which is connected to the space outside the body 110 and the heat dissipation cavity 1104 .

[0070] During operation, the gas flowing in the heat dissipation cavity 1104 forms a heat dissipation airflow ( Figure 4 Arrows d and e in the middle represent heat dissipation airflow. Based on the characteristics of the fluid medium, during the flow of the fluid medium, the pressure in the area with a high flow rate is relatively low. Due to the presence of the heat dissipation airflow, the pressure in the heat dissipation cavity 1104 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 122, and an external air flow is formed in the air duct 122. The external air flow flows from the air duct 122 to the heat dissipation cavity 1104. After entering the heat dissipation cavity 1104, the external air flow merges into the heat dissipation airflow, allowing the heat dissipation cavity 1104 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 1104, thereby preventing users from being scalded by the heat dissipation airflow discharged from the heat dissipation cavity 1104, thereby eliminating the safety hazard of the air fryer 100 easily scalding users and solving the technical problems existing in the related art. This further achieves the technical effect of optimizing the structure of the air fryer 100 and improving the safety and reliability of the air fryer 100.

[0071] like Figure 5 As shown, in some embodiments of the present invention, specifically, the air duct 122 only connects the space outside the body 110 and the heat dissipation cavity 1104 .

[0072] In this technical solution, the air duct 122 only connects the space outside the body 110 and the heat dissipation cavity 1104, and is not connected to the cooking cavity 1102. In this case, the air duct 122 can be used to compress external air into the air duct 122 due to the pressure difference. Specifically, an external air flow is formed within the air duct 122. The external air flow flows from the air duct 122 to the heat dissipation cavity 1104. After entering the heat dissipation cavity 1104, the external air flow merges with the heat dissipation air flow, allowing the heat dissipation cavity 1104 to continuously draw in external air during operation. The external air is then used to lower the temperature of the heat dissipation air flow discharged from the heat dissipation cavity 1104, thereby preventing users from being scalded by the heat dissipation air flow discharged from the heat dissipation cavity 1104. This eliminates the safety hazard of the air fryer 100 that can easily cause burns to users and solves the technical problems existing in the related art. This further achieves the technical effect of optimizing the structure of the air fryer 100 and improving the safety and reliability of the air fryer 100.

[0073] like Figure 2 As shown, in some technical solutions of the present invention, specifically, at least part of the air duct 122 connects the space outside the body 110 and the heat dissipation cavity 1104 , and at least part of the air duct 122 connects the space outside the body 110 and the cooking cavity 1102 .

[0074] In this technical solution, a partial area of ​​the air duct 122 communicates with the space outside the body 110 and the heat dissipation cavity 1104 , and another partial area of ​​the air duct 122 communicates with the space outside the body 110 and the cooking cavity 1102 .

[0075] On this basis, the gas flowing in the cooking cavity 1102 forms an internal circulation airflow in the cooking cavity 1102 ( Figure 3 Arrows b and c in the middle indicate the internal circulation airflow. Based on the characteristics of the fluid medium, during the flow of the fluid medium, the pressure in the area with a high flow rate is relatively low. Due to the existence of the internal circulation airflow, the pressure in the cooking cavity 1102 is relatively low compared to the pressure of the external environment of the body 110. Under the action of the pressure difference, the external gas is pressed into the air duct 122, and an external air flow is formed in the air duct 122 ( Figure 2 、 Figure 3 、 Figure 4 and Figure 5 Arrow a in the figure indicates the flow of external air. This air flows from air duct 122 into cooking cavity 1102. Once inside cooking cavity 1102, it joins the internal circulating airflow, 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. This optimizes the structure of air fryer 100, improves the quality of cooked food, and enhances the user experience.

[0076] like Figure 2 As shown, in some embodiments of the present invention, specifically, the air duct 122 includes: a first air duct 1222, the first end of the first air duct 1222 is connected to the space outside the main body 110, and the second end of the first air duct 1222 is connected to the cooking cavity 1102; a second air duct 1224, the first end of the second air duct 1224 is connected to the first air duct 1222, and the second end of the second air duct 1224 is connected to the heat dissipation cavity 1104.

[0077] In this embodiment, the air duct 122 includes a first air duct 1222 and a second air duct 1224. The first end of the first air duct 1222 is connected to the space outside the main body 110, and the second end of the first air duct 1222 is connected to the cooking cavity 1102. The air flow introduced from the outside can be merged into the cooking cavity 1102 through the first air duct 1222 to adjust the temperature, humidity and oxygen content in the cooking cavity 1102. The second air duct 1224 is connected to the first air duct 1222, and the first end of the second air duct 1224 is connected to the first air duct 1222, and the second end of the second air duct 1224 is connected to the heat dissipation cavity 1104. The external air flow flowing in from the first end of the first air duct 1222 is split at the intersection area of ​​the first air duct 1222 and the second air duct 1224, with one part flowing to the cooking cavity 1102 and the other part flowing to the heat dissipation cavity 1104, thereby reducing the temperature value of the heat dissipation airflow in the heat dissipation cavity 1104 on the basis of meeting the environmental parameter adjustment requirements in the cooking cavity 1102, so that the air fryer 100 takes into account both practicality and safety.

[0078] By providing a second air duct 1224 connected to the first air duct 1222, the structural complexity of the air duct 122 can be reduced. On the one hand, the cost of the air induced component 120 can be reduced, and on the other hand, convenient conditions can be provided for the miniaturization and lightweight design of the air fryer 100.

[0079] like Figure 5 As shown, in some technical solutions of the present invention, specifically, the air duct 122 includes: a fourth air duct 1228 , a first end of the fourth air duct 1228 is connected to the space outside the body 110 , and a second end of the fourth air duct 1228 is connected to the heat dissipation cavity 1104 .

[0080] In this technical solution, the air duct 122 is only connected to the heat dissipation cavity 1104 and is not connected to the cooking cavity 1102 .

[0081] Specifically, the first end of the fourth air duct 1228 is connected to the space outside the main body 110, and the second end of the fourth air duct 1228 is connected to the heat dissipation cavity 1104. The air flow introduced from the outside can be merged into the heat dissipation cavity 1104 through the fourth air duct 1228, thereby reducing the temperature value of the heat dissipation air flow in the heat dissipation cavity 1104, so that the air fryer 100 takes into account both practicality and safety.

[0082] like Figure 1 As shown, in some embodiments of the present invention, specifically, the main body 110 also includes a heat dissipation channel 1106, which is at least partially located in the heat dissipation cavity 1104, and a heat dissipation fan is provided in the heat dissipation cavity; the heat dissipation channel 1106 includes an inlet and an outlet, both of which are connected to the heat dissipation cavity, and the air duct 122 is connected to the heat dissipation channel 1106.

[0083] In this embodiment, a heat dissipation channel 1106 is also provided in the main body 110. The heat dissipation channel 1106 is at least partially located in the heat dissipation cavity 1104. The inlet and outlet of the heat dissipation channel 1106 are both connected to the heat dissipation cavity 1104. The air duct 122 is connected to the heat dissipation channel 1106. The air flow introduced from the outside can be merged into the heat dissipation channel 1106 under the action of the pressure difference.

[0084] On this basis, a cooling fan is provided in the heat dissipation cavity 1104. The rotating cooling fan can drive the gas flow in the heat dissipation cavity 1104, thereby increasing the flow rate of the heat dissipation airflow. The high-speed heat dissipation airflow enters the heat dissipation channel 1106 from the inlet and flows out of the heat dissipation channel 1106 from the outlet.

[0085] By increasing the air flow rate within the heat dissipation channel 1106 through the heat dissipation fan, the pressure difference between the space outside the body 110 and the heat dissipation channel 1106 can be increased, thereby increasing the introduction rate of the external air flow, and further enhancing the heat dissipation effect of the external air flow on the heat dissipation cavity 1104, thereby preventing the user from being scalded by the heat dissipation airflow discharged from the heat dissipation cavity 1104. This eliminates the safety hazard of the air fryer 100 easily scalding the user and solves the technical problems existing in the related art. This further achieves the technical effect of optimizing the structure of the air fryer 100 and improving the safety and reliability of the air fryer 100.

[0086] During operation, the heat generated by the hot air assembly 130 first diffuses into the heat dissipation cavity 1104, then enters the heat dissipation channel 1106 along with the heat dissipation airflow, and is ultimately guided out of the body 110 through the heat dissipation channel 1106. The provision of the heat dissipation channel 1106 allows the heat in the heat dissipation cavity 1104 to be discharged in a centralized manner. This not only reduces the area of ​​the high-temperature region on the outer shell of the body 110, but also increases the exhaust rate of the heat dissipation airflow through the heat dissipation channel 1106, which has a smaller flow area.

[0087] On this basis, the second end of the second air duct 1224 is connected to the heat dissipation channel 1106, or the second end of the fourth air duct 1228 is connected to the heat dissipation channel 1106. The heat dissipation airflow will continue to absorb heat while flowing in the heat dissipation cavity 1104. If the second end of the second air duct 1224 or the second end of the fourth air duct 1228 is connected to the heat dissipation cavity 1104 outside the heat dissipation channel 1106, the external airflow will also absorb heat and increase in temperature before entering the heat dissipation channel 1106, resulting in the cooling effect of the external airflow on the heat dissipation airflow that is ultimately discharged being affected. In this regard, by connecting the second end of the second air duct 1224 or the second end of the fourth air duct 1228 to the heat dissipation channel 1106, the external airflow can be merged into the heat dissipation airflow just before the heat dissipation airflow is about to be discharged from the main body 110, thereby enhancing the cooling effect of the external airflow on the heat dissipation airflow and reducing the temperature of the heat dissipation airflow discharged from the outlet, thereby achieving the technical effect of optimizing the structure of the air induction component 120 and improving the safety of the air fryer 100.

[0088] In some embodiments of the present invention, specifically, the cooling fan includes an air outlet side and an air return side; the inlet of the cooling channel 1106 is located on the air outlet side of the cooling fan, and the extension direction of the cooling channel 1106 is consistent with the air outlet direction of the cooling fan.

[0089] In this technical solution, the heat dissipation fan includes an air outlet side and an air return side. The heat dissipation fan can be a centrifugal fan. The air outlet side is located on the peripheral side of the centrifugal fan, and the return side is located on the side facing the centrifugal fan.

[0090] The inlet of the heat dissipation channel 1106 is arranged on the peripheral side of the centrifugal fan, so that the heat dissipation airflow blown by the centrifugal fan can smoothly enter the heat dissipation channel 1106, ensuring a sufficiently large pressure difference between the heat dissipation channel 1106 and the external space of the body 110.

[0091] On this basis, the heat dissipation channel 1106 extends along the circumferential direction of the centrifugal fan around the centrifugal fan. By extending the heat dissipation duct 122 along the circumference of the centrifugal fan, the extension direction of the heat dissipation duct 122 can be made consistent with the flow direction of the heat dissipation airflow blown out by the centrifugal fan, thereby reducing the resistance of the heat dissipation duct 122 to the heat dissipation airflow, increasing the gas flow rate in the heat dissipation duct 122, and then increasing the pressure difference between the heat dissipation duct 122 and the external space of the main body 110 to increase the introduction rate of the airflow introduced from the outside.

[0092] Correspondingly, the heat dissipation fan may also be an axial flow fan, with the air outlet side located on the side facing the axial flow fan and the air return side located on the side facing away from the axial flow fan.

[0093] The inlet of the heat dissipation channel 1106 is arranged on the side facing the axial flow fan, so that the heat dissipation airflow blown by the axial flow fan can smoothly enter the heat dissipation channel 1106, ensuring that there is a sufficiently large pressure difference between the heat dissipation channel 1106 and the external space of the body 110.

[0094] On this basis, the heat dissipation channel 1106 extends along the axial direction of the axial fan on the side facing the axial fan, so that the extension direction of the heat dissipation duct 122 is consistent with the flow direction of the heat dissipation airflow blown out by the axial fan, thereby reducing the resistance of the heat dissipation duct 122 to the heat dissipation airflow, increasing the gas flow rate in the heat dissipation duct 122, and then increasing the introduction rate of the air flow introduced from the outside by increasing the pressure difference between the heat dissipation duct 122 and the external space of the main body 110.

[0095] In some embodiments of the present invention, specifically, the flow area of ​​the connecting end of the air duct 122 and the heat dissipation channel 1106 is smaller than the flow area of ​​the inlet; the connecting end of the air duct 122 and the heat dissipation channel 1106 is located on the side of the heat dissipation cavity 1104 facing away from the cooking cavity 1102.

[0096] In this embodiment, the flow area of ​​the second end of the second air duct 1224 is the first area, or the flow area of ​​the second end of the fourth air duct 1228 is the first area, and the flow area of ​​the inlet of the heat dissipation channel 1106 is the second area, wherein the first area is smaller than the second area.

[0097] By limiting the size relationship between the first area and the second area, the air flow introduced from the outside can accelerate the heat dissipation airflow in the heat dissipation channel 1106 when it merges into the heat dissipation channel 1106, so as to increase the discharge rate of the heat dissipation airflow, thereby, on the one hand, improving the heat dissipation effect of the heat dissipation cavity 1104 and the heat dissipation air duct 122 on the hot air component 130, and on the other hand, reducing the temperature of the discharged heat dissipation airflow, thereby achieving the technical effect of improving the safety and reliability of the air fryer 100.

[0098] In some embodiments of the present invention, specifically, in the flow direction of the heat dissipation channel 1106 , the distance between the connecting end of the air duct 122 and the heat dissipation channel 1106 and the inlet is greater than the distance between the connecting end of the air duct 122 and the heat dissipation channel 1106 and the outlet.

[0099] In this embodiment, the heat dissipation airflow flows from the inlet of the heat dissipation channel 1106 to the outlet of the heat dissipation channel 1106. In the flow direction of the heat dissipation airflow, the flow distance between the second end of the second air duct 1224 and the inlet is the first distance, or the flow distance between the second end of the fourth air duct 1228 and the inlet is the first distance, the flow distance between the second end of the second air duct 1224 and the outlet is the second distance, or the flow distance between the second end of the fourth air duct 1228 and the outlet is the second distance, wherein the first distance is greater than the second distance.

[0100] By limiting the above-mentioned distance relationship, the confluence position of the air flow introduced from the outside can be made close to the outlet of the heat dissipation channel 1106. After the air flow introduced from the outside merges into the heat dissipation channel 1106, it will also absorb the heat in the heat dissipation cavity 1104. Shortening the distance between the confluence position and the outlet can reduce the amount of heat absorbed by the air flow introduced from the outside after it merges, thereby reducing the temperature of the heat dissipation airflow discharged from the outlet of the heat dissipation channel 1106, reducing the possibility of the user being scalded by the heat dissipation airflow, and thus achieving the technical effect of improving the safety of the air fryer 100.

[0101] Specifically, the heat dissipation channel 1106 includes an exhaust cover, the outlet of the heat dissipation channel 1106 is set on the exhaust cover, and the second end of the second air duct 1224 is connected to the exhaust cover so that the confluence area of ​​the air flow introduced from the outside is close to the outlet.

[0102] On this basis, the connecting end of the air duct 122 and the heat dissipation channel 1106 is located on the side of the heat dissipation cavity 1104 facing away from the cooking cavity 1102. By setting the connecting end of the air duct 122 and the heat dissipation channel 1106 away from the cooking cavity 1102, the heat in the cooking cavity 1102 can be prevented from affecting the heat dissipation effect of the air flow introduced from the outside on the heat dissipation cavity 1104, and the temperature of the heat dissipation airflow discharged from the outlet of the heat dissipation channel 1106 can be reduced.

[0103] like Figure 3 As shown, in some embodiments of the present invention, specifically, the air duct 122 also includes: a third air duct 1226, the third air duct 1226 is located in the cooking cavity 1102, the first end and the second end of the third air duct 1226 are both connected to the cooking cavity 1102, and the second end of the first air duct 1222 is connected to the third air duct 1226.

[0104] In this embodiment, the air duct 122 further includes a third air duct 1226. The first end of the third air duct 1226 communicates with the cooking cavity 1102, and the second end of the third air duct 1226 also communicates with the cooking cavity 1102. The second end of the first air duct 1222 communicates with the middle section of the third air duct 1226. The first end of the first air duct 1222 extends toward the outer surface of the body 110 and ultimately communicates with the space outside the body 110. In other words, the third air duct 1226 connects two different areas within the cooking cavity 1102, while the first air duct 1222 connects the cooking cavity 1102 and the outside of the air fryer 100.

[0105] During operation, gas flowing within cooking cavity 1102 flows into third duct 1226 from one of its first and second ends, and ultimately exits third duct 1226 from the other end, forming an internal circulation airflow within third duct 1226. 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 flow channel is lower than the pressure outside the main body 110. This pressure differential forces external gas into first duct 1222, forming an external airflow within first duct 1222. The external airflow flows from the second end of first duct 1222 to the first end of first duct 1222. After entering third duct 1226, the external airflow merges with the internal circulation airflow and ultimately flows into cooking cavity 1102, allowing cooking cavity 1102 to continuously draw in external air 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.

[0106] Compared with the solution in which the second end of the first air duct 1222 is directly connected to the cooking cavity 1102, the internal circulating airflow can be accelerated inside the third air duct 1226, thereby increasing the pressure difference between the third air duct 1226 and the external environment, so as to increase the introduction rate of the air flow introduced from the outside, and thereby improve the regulation effect of the temperature value, humidity value and oxygen content in the cooking cavity 1102.

[0107] In some embodiments of the present invention, specifically, the flow area of ​​the second end of the first air duct 1222 is greater than the flow area of ​​the first end of the third air duct 1226, and / or the flow area of ​​the second end of the first air duct 1222 is greater than the flow area of ​​the second end of the third air duct 1226.

[0108] In this embodiment, the flow area of ​​the second end of the first air duct 1222 is a third area, and the flow area of ​​the first end and / or the second end of the third air duct 1226 is a fourth area, wherein the third area is smaller than the fourth area.

[0109] By limiting the size relationship between the third area and the fourth area mentioned above, the air flow introduced from the outside can accelerate the internal circulation air flow in the third air duct 1226 when it merges into the third air duct 1226, so as to increase the circulation rate of the internal circulation air flow and the merging rate of the air flow introduced from the outside, thereby improving the regulating effect of the air flow introduced from the outside on the temperature value, humidity value and oxygen content in the cooking cavity 1102.

[0110] like Figure 2As shown, in some embodiments of the present invention, specifically, the air fryer 100 further includes: a flow regulating component 140 connected to the air duct 122 , and the flow regulating component 140 is used to regulate the flow of the first air duct 1222 and / or the second air duct 1224 .

[0111] In this embodiment, the air fryer 100 further includes a flow regulating assembly 140 connected to the air induction assembly 120. The air fryer 100 can adjust the flow rate in the air duct 122 by controlling the operating state of the flow regulating assembly 140. Specifically, when the current cooking needs require a closed cooking environment, the flow regulating assembly 140 is controlled to close the first air duct 1222 to block the airflow within the first air duct 1222, thereby eliminating the pressure difference between the inside and outside of the duct and stopping the introduction of external air. When the current cooking needs require the introduction of external air, the flow regulating assembly 140 is controlled to open the first air duct 1222, thereby creating a pressure difference between the inside and outside of the duct and introducing external air into the cooking cavity 1102. The flow regulating assembly 140 can be controlled to adjust the opening of the air duct 122 to adjust the flow rate and flow of the internal circulating airflow within the cooking cavity 1102, thereby correspondingly adjusting the amount of external air introduced and the rate of external air introduction.

[0112] It can be seen that by setting the flow regulating component 140, the air fryer 100 can control the flow regulating component 140 to switch the ventilation process on and off, and adjust the ventilation rate, to ensure that the current external air introduction rate can adapt to the cooking process, and to ensure that the humidity value, oxygen content and other parameters in the cooking cavity 1102 can meet the cooking requirements, thereby optimizing the structure of the air fryer 100, improving the practicality and controllability of the air fryer 100, improving the quality of the cooked food, and improving the user experience.

[0113] Specifically, the flow regulating component 140 can also independently control the flow of the second air duct 1224. For example, when the air fryer 100 is in the keep-warm state or standby state, the hot air component 130 no longer produces heat. At this time, closing the second air duct 1224 can stop the introduction of external air flow into the heat dissipation cavity 1104.

[0114] like Figure 2 As shown, in some embodiments of the present invention, specifically, the flow regulating component 140 is disposed in the first air duct 1222 , and the flow regulating component 140 is located between the first end of the first air duct 1222 and the first end of the second air duct 1224 .

[0115] In this embodiment, the flow regulating component 140 is disposed in the first air duct 1222 , and the flow regulating component 140 is located between the first end of the first air duct 1222 and the first end of the second air duct 1224 .

[0116] When the air fryer 100 is in standby mode or performing a keep-warm process, the flow regulating assembly 140 controls the first air duct 1222 to close, thereby preventing external air from entering the first air duct 1222 and the second air duct 1224. When the air fryer 100 begins heating food, the flow regulating assembly 140 controls the first air duct 1222 to open, allowing external air to enter the first air duct 1222 and then be diverted to the cooking chamber 1102 and the heat dissipation chamber 1104.

[0117] It can be seen that by setting the flow regulating component 140 between the first end of the first air duct 1222 and the intersection area of ​​the second air duct 1224 and the first air duct 1222, the flow regulating component 140 can synchronously control the flow of the first air duct 1222 and the second air duct 1224, which is beneficial to reducing the cost and electrical control complexity of the air fryer 100.

[0118] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, optionally, the air fryer 100 further includes: a base 160, which is disposed on the main body 110; a cover 162, which covers the base 160, and the cover 162 includes an air inlet 1622. 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 air duct 122; a fan 164, which is disposed in the installation cavity 1602, and the airflow flowing into the air duct 122 can drive the fan 164 to rotate.

[0119] In this embodiment, the air fryer 100 further includes a base 160, a cover 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 1222. The fan 164 is rotatably connected to the base 160. The cover 162 is attached to the base 160. After the cover 162 is assembled, the cover 162 and the base 160 enclose an installation cavity 1602. The installation cavity 1602 communicates with the first air duct 1222 via the through hole. The cover 162 also has an air inlet 1622, which communicates with the installation cavity 1602 or introduces air into the heat dissipation cavity 1104 through the fourth air duct 1228.

[0120] 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 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 1222 and the second air duct 1224 to meet the air supply needs of the cooking cavity 1102.

[0121] 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.

[0122] In some embodiments of the present invention, optionally, the cover 162 is a light-transmitting cover.

[0123] In this embodiment, the cover 162 is made of a light-transmitting material to produce a light-transmitting cover.

[0124] 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.

[0125] Specifically, the cover 162 can be made of materials such as glass and plastic.
