Description

Technical Field

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

[0002] Currently, when an air fryer is in operation, the fan in the cooking chamber drives air through the heating element, allowing the high-temperature air to circulate within the cooking chamber to cook the ingredients. During the cooking process, the high-temperature air evaporates the moisture carried by the ingredients. Once the moisture enters the cooking chamber, it increases the humidity of the air inside the cooking chamber, thereby affecting the air frying effect.

[0003] In the related art, in order to reduce the air humidity in the cooking cavity, an exhaust port connected to the cooking cavity is provided. Under the action of pressure, the gas in the cooking cavity carries a certain amount of water vapor and is discharged from the cooking cavity through the exhaust port. However, due to the small pressure difference between the cooking cavity and the outside, the exhaust volume of the cooking cavity is small, and the efficiency of the air fryer in discharging water vapor is low, resulting in poor cooking effect on the ingredients. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] To this end, one aspect of the present invention proposes an air fryer, which includes a main body and an air induced draft assembly, the main body is provided with a cooking cavity and an exhaust port, and the exhaust port is connected to the cooking cavity; the air induced draft assembly is arranged on the main body, and the air induced draft assembly is provided with a first air duct, the first end of the first air duct is connected to the cooking cavity, and the second end of the first air duct extends to the outside of the main body; wherein, the gas in the cooking cavity can be discharged from the cooking cavity through the exhaust port, and the gas outside the air fryer can enter the cooking cavity through the first air duct.

[0006] The air fryer proposed in the utility model comprises a body and an air induction assembly, wherein the body is provided with a cooking cavity for preventing food from being heated and cooking, and an exhaust port is provided on the body, the exhaust port being connected to the cooking cavity for exhausting water vapor generated during cooking from the cooking cavity.

[0007] The air induction assembly is integrated with the main body and is provided with a first air duct. The first end of the first air duct is connected to the cooking cavity, and the second end of the first air duct extends outside the main body. The first air duct not only allows gases (including water vapor, oil smoke, etc.) in the cooking cavity to be discharged through the exhaust port, but also allows fresh air outside the air fryer to enter the cooking cavity through the first air duct.

[0008] In conventional air fryers, as cooking progresses, moisture and air are continuously exhausted from the cooking chamber. If fresh air is not replenished promptly, the pressure within the chamber will decrease, creating a vacuum-like state. This can seriously affect the further exhaust of moisture and cooking efficiency. The present invention utilizes an air induction assembly and a first air duct to achieve an air intake function. Gas within the cooking chamber can be exhausted from the cooking chamber through the exhaust port, while gas from outside the air fryer can enter the cooking chamber through the first air duct. This allows for continuous intake of external air into the cooking chamber, which is promptly replenished with fresh air, maintaining a stable pressure and effectively preventing the vacuum phenomenon. This allows the air fryer to efficiently exhaust moisture.

[0009] Continuous fresh air replenishment not only maintains sufficient oxygen in the cooking chamber, helping to evenly heat and cook food quickly, but also ensures that moisture is promptly removed during the cooking process, preventing condensation on the food surface that affects taste and appearance. The air circulation driven by the induced draft assembly, combined with the intake and exhaust design of the first air duct, forms a highly efficient air exchange system, resulting in more even heat distribution within the cooking chamber, shortened cooking time, and improved food taste.

[0010] The present application discharges water vapor through the exhaust port. The timely discharge of water vapor helps to maintain a dry environment in the cooking cavity. The dry environment helps to form a crispy crust on the surface of the food, thereby improving the crispy baking effect.

[0011] As air is exhausted through the exhaust port, the pressure inside the cooking chamber decreases, allowing outside air to flow in smoothly. Fresh air from outside the air fryer enters the cooking chamber through the first air duct. The removal of moisture and the intake of outside air improve air circulation within the cooking chamber, preventing air pollution and odor accumulation. This continuous exchange of fresh air with the air inside the cooking chamber removes harmful gases and odors generated during cooking, improving the taste and quality of cooked food.

[0012] During the cooking process, aldehydes in food are important components that characterize the aroma of the food. This application can promote the generation and accumulation of aldehydes by optimizing the cooking environment, that is, keeping the cooking cavity dry and introducing air. Specifically, it can increase the aldehydes in food by 20%, thereby significantly improving the aroma of the food.

[0013] During the cooking process, ingredients may produce harmful substances such as acrylamide and heterocyclic amines. By introducing air, the generation of these harmful substances can be reduced. Specifically, the generation of harmful substances such as acrylamide and heterocyclic amines can be reduced by 30%, thereby reducing the potential harm of food to the human body. In summary, the air fryer proposed by the utility model allows the cooking chamber to be replenished with air in a timely manner through the air induction component and the first air duct, effectively solving the problem of poor exhaust caused by the reduced pressure in the cooking chamber in the late stage of cooking in traditional air fryers. It not only improves cooking efficiency, but also ensures the taste and nutritional value of food, reduces the potential harm of food to the human body, and brings users a better cooking experience.

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

[0015] In some technical solutions of the present invention, the air fryer optionally further includes: a first fan blade, a first drive assembly, and an airflow adjustment component. The first fan blade is disposed within the cooking cavity; the first drive assembly is connected to the first fan blade; and the airflow adjustment component is located on one side of the exhaust port and is arranged obliquely relative to the inner wall of the cooking cavity. When the first drive assembly drives the first fan blade to rotate, airflow is generated within the cooking cavity, and the airflow adjustment component is capable of adjusting the flow direction and flow rate of at least part of the airflow so that at least part of the airflow flows out of the cooking cavity through the exhaust port.

[0016] In this technical solution, the air fryer further includes a first fan blade, a first drive assembly, and an airflow regulating component. The first fan blade is disposed in the cooking cavity, and the first drive assembly is connected to the first fan blade and is capable of driving the first fan blade to rotate, thereby forming an airflow in the cooking cavity to move water vapor.

[0017] The airflow regulating component is located on one side of the exhaust port and is arranged obliquely relative to the inner wall of the cooking cavity. When the first driving assembly drives the first fan blade to rotate, airflow can be generated in the cooking cavity. The airflow regulating component can adjust the flow direction and flow rate of at least part of the airflow so that at least part of the airflow flows out of the cooking cavity through the exhaust port.

[0018] When the air fryer is operating, the high-temperature airflow evaporates moisture from the ingredients as they cook in the cooking chamber. This moisture then enters the cooking chamber, increasing the humidity within the chamber. The drive assembly rotates the first fan blade, creating a flow of air. At least a portion of this airflow is blocked by the airflow regulating component upon reaching it. This airflow is then directed directly toward the exhaust port, thereby increasing the rate at which moisture is discharged from the cooking chamber.

[0019] The airflow regulating component can guide the airflow within the cooking chamber to the exhaust port, where it is then discharged from the cooking chamber. After the gas is discharged from the cooking chamber, the air pressure inside the cooking chamber is lower than the ambient air pressure, allowing air to flow more smoothly into the cooking chamber. This allows for the continuous exchange of fresh air with the air inside the cooking chamber, promoting the formation and accumulation of aldehydes. Specifically, it can increase aldehyde levels in food by 20%, significantly enhancing the aroma of the food. The airflow regulating component guides the smooth outflow of gas from the cooking chamber, allowing the outside air to flow smoothly into the cooking chamber after the pressure inside the cooking chamber is reduced. This air exchange can reduce the formation of harmful substances, specifically, by 30% for harmful substances such as acrylamide and heterocyclic amines, thereby reducing the potential harm of food to the human body.

[0020] The airflow regulating component guides the airflow to be discharged in time, which helps to maintain a dry environment in the cooking cavity. The dry environment helps to form a crispy crust on the surface of the food and improves the crispy baking effect.

[0021] During the cooking process, the humidity in the cooking cavity will change as the food is heated and the water evaporates. The air flow rate is changed by changing the flow area through the air flow adjustment component, thereby improving the cooking effect.

[0022] The airflow control component not only controls the direction and volume of airflow but also regulates temperature. Specifically, the hot air in the cooking cavity is guided by the airflow control component, allowing the hot air to escape and cool air from the outside environment to enter the cooking cavity. The flow of hot and cold air adjusts the temperature within the cooking cavity to meet adaptability needs, such as cooling the food at the end of cooking or fine-tuning the temperature mid-cooking, for optimal cooking results.

[0023] Specifically, when cooking is nearly complete, the airflow regulating component is adjusted to increase the exhaust speed of the hot airflow in the cooking cavity, thereby rapidly cooling the food, which helps prevent overcooking of the food and maintains its taste and color.

[0024] The utility model blocks at least part of the airflow through the airflow regulating component, so that the airflow flows out of the cooking cavity through the exhaust port, and guides the flow of the airflow in the cooking cavity. It is not necessary to rely on forming a large pressure difference between the cooking cavity and the outside world to discharge a large amount of water vapor from the cooking cavity, thereby increasing the rate at which water vapor is discharged from the cooking cavity, adjusting the humidity in the cooking cavity, and improving the taste of cooked ingredients.

[0025] In some technical solutions of the present invention, optionally, the airflow adjustment component can rotate relative to the inner wall of the cooking cavity.

[0026] In this technical solution, the airflow adjustment component is capable of rotating relative to the inner wall of the cooking chamber, thereby adjusting the exhaust volume. Specifically, within the cooking chamber, air is stirred by the first fan blade to flow. The airflow adjustment component is located on one side of the exhaust port and is arranged at an angle relative to the inner wall of the cooking chamber. Some air strikes the airflow adjustment component and is directed toward the exhaust port, while the remaining air not obstructed by the airflow adjustment component remains in the cooking chamber and participates in cooking. By enabling the airflow adjustment component to rotate relative to the inner wall of the cooking chamber, the amount of air striking the airflow adjustment component can be varied, thereby achieving efficient and convenient adjustment of the exhaust volume.

[0027] The airflow regulating component can rotate relative to the inner wall of the cooking cavity to achieve efficient and convenient adjustment of the exhaust volume, thereby adjusting the exhaust volume while also adjusting the air intake volume of the first air duct. Specifically, when the airflow regulating component rotates to a position with a larger angle relative to the exhaust port, the exhaust volume of the exhaust port increases, thereby increasing the pressure difference between the pressure in the cooking cavity and the pressure outside the air fryer. Under the action of the larger pressure difference, the air intake volume of the first air duct also increases, thereby adjusting the air intake volume of the first air duct. Conversely, when the airflow regulating component rotates to a position with a smaller angle relative to the exhaust port, the exhaust volume of the exhaust port decreases, thereby decreasing the pressure difference between the pressure in the cooking cavity and the pressure outside the air fryer. Under the action of the smaller pressure difference, the air intake volume of the first air duct also decreases, thereby adjusting the air intake volume of the first air duct.

[0028] During the cooking process, the humidity in the cooking cavity will change as the food is heated and the water evaporates. By rotating the airflow regulating component, the flow area is changed, thereby changing the air flow rate.

[0029] Specifically, when the humidity in the cooking cavity is too high, the airflow adjustment component will rotate to increase the flow area, thereby increasing the air flow rate, helping to discharge excess water vapor in the cooking cavity and reduce the humidity level.

[0030] When the humidity is too low, the airflow adjustment component will rotate to reduce the circulation area and reduce the air flow, thereby maintaining the humidity in the cooking cavity.

[0031] The airflow regulating component in this application adjusts the air flow rate out of the cooking cavity, changing the pressure within the cooking cavity, allowing outside air to enter the cooking cavity smoothly. This improves the air quality within the cooking cavity. By precisely regulating the humidity within the cooking cavity and the air flow rate, the airflow regulating component helps reduce the amount of harmful substances generated in food during the cooking process.

[0032] Specifically, high humidity and an oxygen-deficient environment are favorable conditions for the production of harmful substances such as acrylamide. By reducing the humidity in the cooking cavity and increasing the air intake flow rate, the oxygen content and humidity distribution in the cooking cavity can be improved, thereby reducing the generation of harmful substances such as acrylamide.

[0033] Heterocyclic amines are another harmful substance produced during high-temperature cooking. By adjusting the humidity and air intake in the cooking chamber, the cooking temperature can be controlled and the generation of heterocyclic amines can be reduced.

[0034] In some technical solutions of the present invention, optionally, the air fryer further includes a connecting rod and a knob, wherein the first end of the connecting rod is connected to the airflow regulating component; and the knob is connected to the second end of the connecting rod.

[0035] In this technical solution, the air fryer further comprises a connecting rod and a knob, which constitute a component for adjusting the angle of the airflow regulating component relative to the inner wall of the cooking cavity.

[0036] The first end of the connecting rod is connected to the airflow adjustment component, and the knob is connected to the second end of the connecting rod. By applying force to the knob to rotate the knob, the knob can control the connecting rod, and then adjust the position of the airflow adjustment component, so as to conveniently adjust the angle of the airflow adjustment component relative to the inner wall of the cooking cavity, so that the user can conveniently control the exhaust volume during the cooking process through manual control, thereby adjusting the cooking effect of the ingredients.

[0037] In some technical solutions of the present invention, optionally, the knob is arranged on the top of the body and exposed from the body.

[0038] In this technical solution, the knob is set at the top of the main body and exposed to the main body, so that the user can intuitively see the knob and operate it easily. The main function of the knob is to control the movement of the connecting rod, and then adjust the rotation angle of the airflow adjustment component connected to the connecting rod to achieve exhaust volume adjustment.

[0039] In some technical solutions of the present invention, optionally, the air fryer further includes a second driving assembly, which is connected to the airflow regulating component and can drive the airflow regulating component to rotate relative to the inner wall of the cooking cavity.

[0040] In this technical solution, the air fryer also includes a second drive assembly, which is connected to the airflow adjustment component. The air fryer is provided with a second drive assembly, which is connected to the airflow adjustment component and can drive the airflow adjustment component to rotate relative to the inner wall of the cooking cavity, providing users with a more convenient and accurate exhaust volume adjustment method.

[0041] In some technical solutions of the present invention, optionally, the air fryer also includes a humidity detection component and a control component, the humidity detection component can detect the humidity in the cooking cavity; the control component is arranged in the main body, electrically connected to the second drive component, and electrically connected to the humidity detection component, and the control component can control the second drive component to drive the airflow adjustment component to rotate according to the humidity in the cooking cavity.

[0042] In this technical solution, the air fryer also includes a humidity detection component and a control component. The humidity detection component is installed in the cooking cavity of the air fryer and is used to detect the humidity level in the cooking cavity in real time.

[0043] The control assembly is housed within the main body and is electrically connected to the second drive assembly and the humidity detection component. The control assembly controls the second drive assembly to rotate the airflow control component based on the humidity within the cooking chamber. When the air fryer begins operation, the humidity detection component begins detecting the humidity level within the cooking chamber. The control assembly reads the data transmitted by the humidity detection component and compares it with a preset humidity threshold. Based on the comparison between the humidity data and the threshold, the control assembly sends a command to the second drive assembly to control the rotation of the airflow control component. This design allows the air fryer to more intelligently adjust the humidity within the cooking chamber during cooking, thereby improving the cooking quality of the ingredients.

[0044] In some technical solutions of the present invention, optionally, in the movement direction of the airflow in the cooking cavity, the first side of the airflow adjustment component is located on the leeward side of the exhaust port, and the second side of the airflow adjustment component extends toward the upwind side of the exhaust port.

[0045] In this technical solution, the airflow regulating component is positioned based on the direction of airflow within the cooking cavity. Specifically, the first side of the airflow regulating component is located downwind of the exhaust port, while the second side of the airflow regulating component extends upwind of the exhaust port. When the air fryer is operating, hot air circulates within the cooking cavity, typically being heated from the bottom or sides and blown toward the food, where it then rises and passes over the food surface before being exhausted through the exhaust port. In this design, the first side of the airflow regulating component is located near the exhaust port, while the second side faces the source of the air.

[0046] The airflow adjustment component is located in the airflow path and can effectively control the direction and speed of the airflow. By adjusting the angle of the airflow adjustment component, users can more precisely control the efficiency of water vapor discharge in the cooking chamber, thereby achieving more ideal cooking results.

[0047] In some technical solutions of the present invention, optionally, a second air duct is provided in the cooking cavity. The second air duct is located at the second end of the first air duct, extends along the flow direction of the airflow in the cooking cavity, and is connected to the first air duct.

[0048] In this technical solution, a second air duct is provided in the cooking cavity. The second air duct is located at the second end of the first air duct, extends along the airflow direction in the cooking cavity, and communicates with the first air duct. The second air duct is a flow channel inside the cooking cavity for guiding airflow.

[0049] When the air fryer is operating, the air inside the cooking chamber is heated and circulated. Due to the design of the cooking chamber's internal flow channel, the air flow velocity increases within the second duct. According to Bernoulli's principle, where the flow velocity increases, the pressure decreases. This decrease in pressure creates a pressure difference with the outside air. Because the outside air pressure is higher, the air is forced from the first duct into the second duct, and ultimately into the cooking chamber.

[0050] The draft control element significantly enhances air flow within the cooking chamber, ensuring even heating of ingredients and improving cooking results. The natural pressure differential draws in outside air, eliminating the need for additional energy consumption and delivering high energy efficiency.

[0051] In some technical solutions of the present invention, optionally, the air fryer further includes an air duct plate, which is connected to the main body, and the air duct plate and the inner wall of the main body form a second air duct; or the air fryer further includes a second pipe, and the second pipe is provided with a second air duct.

[0052] In this technical solution, on the one hand, the air fryer also includes an air duct plate, which is connected to the main body. The air duct plate and the inner wall of the main body form a second air duct to guide and control the flow path of air in the cooking cavity during the cooking process.

[0053] On the other hand, the air fryer also includes a second pipe, which is provided with a second air duct for guiding and controlling the flow of air during the cooking process. The second pipe is directly integrated into the body of the air fryer, making the structure more compact.

[0054] In some technical solutions of the present invention, optionally, an air outlet end of the second air duct faces the airflow regulating component.

[0055] In this technical solution, the outlet end of the second air duct faces the airflow control component, and the airflow from the second air duct first encounters the airflow control component. The amount of air discharged from the cooking cavity can be controlled by adjusting the rotation angle of the airflow control component. This design can be flexibly adjusted to meet different cooking needs to achieve the best cooking effect.

[0056] In some technical solutions of the present invention, optionally, the air fryer further includes a first heating component, and the first heating component is arranged in the first air duct or the second air duct.

[0057] In this technical solution, the air fryer also includes a first heating component, which is an important component of the air fryer and is used to increase the intake air temperature. Specifically, the first heating component is arranged in the first air duct or the second air duct.

[0058] The first heating component is arranged in the air intake system of the air fryer, that is, the first heating component is arranged in the first air duct, or the first heating component is arranged in the second air duct to ensure that the air can be effectively heated when passing through.

[0059] The main function of the first heating component is to increase the temperature of the intake air. When the air fryer starts working, fresh air will pass through the first air duct and the second air duct. During this process, the first heating component will heat the air to raise its temperature to a range suitable for cooking. This heating process helps ensure that the ingredients can be heated evenly, thereby achieving better cooking results.

[0060] In addition, the first heating component is arranged in the first air duct or the second air duct, so that the first heating component can also generate heat radiation to the cooking cavity, thereby improving the cooking effect of the air fryer.

[0061] In some technical solutions of the present invention, optionally, the cross-sectional area of ​​the second air duct decreases from both ends of the second air duct toward the position where the first air duct is located.

[0062] In this technical solution, the shape of the second air duct is limited, and the cross-sectional area of ​​the second air duct decreases from both ends of the second air duct to the position of the first air duct, which helps to accelerate the airflow and increase the air intake.

[0063] According to Bernoulli's principle, when a fluid (such as air) flows through a pipe, if the cross-sectional area of ​​the pipe gradually decreases, the fluid's velocity will increase while the pressure will decrease. This is because when a fluid passes through a pipe with a smaller cross-sectional area, due to the law of conservation of volume, the flow velocity must increase to maintain the same flow rate. This increase in flow velocity causes a decrease in pressure because when kinetic energy increases, potential energy (in this case, pressure) is converted into kinetic energy. As the cross-sectional area of ​​the second air duct gradually decreases, the hot air in the cooking chamber is accelerated as it passes through the second duct. This accelerated airflow helps to better stir and circulate the air in the cooking chamber, ensuring more even heating of the ingredients.

[0064] As the cross-sectional area of ​​the second air duct gradually decreases and the airflow velocity increases, a negative pressure area is created at the entrance of the second air duct (where air enters). This negative pressure area draws more outside air into the second air duct, increasing the air intake. This replenishes the hot air consumed during cooking and maintains a stable temperature within the cooking chamber. Furthermore, the incoming air removes cooking fumes and odors, maintaining a fresh cooking environment.

[0065] In some technical solutions of the present invention, optionally, the air fryer also includes a fan assembly, which is arranged at the second end of the first air duct and exposed to the main body. The fan assembly includes a second fan blade, and the gas flow in the first air duct can drive the second fan blade to rotate.

[0066] In this technical solution, the air fryer further includes a fan assembly. The fan assembly is arranged at the second end of the first air duct and exposed to the body. The fan assembly includes a second fan blade, and the gas flow in the first air duct can drive the second fan blade to rotate.

[0067] The fan assembly is disposed at the second end of the first air duct and is exposed from the main body. Exposing the fan assembly from the main body allows visualization of the internal operation of the fan assembly, allowing the user to observe the rotation of the second fan blade through the exposed fan assembly, thereby determining the air intake status of the cooking chamber. The exposed fan assembly is provided with a light-transmitting cover, allowing intuitive observation of the rotation of the second fan blade within, thereby improving the cooking effect and enhancing the user experience.

[0068] The specific position of the second fan blade can be placed outside the main body, or the second fan blade can be set inside the main body, or a portion of the second fan blade can be set outside the main body and the other portion can be set inside the main body. The setting position of the second fan blade only needs to facilitate the user to observe the rotation of the second fan blade. The fan portion of the second fan blade can be selected with a color with high color differentiation, making it easier for the user to observe the rotation of the second fan blade and providing better feedback to the user on the working status of the air fryer.

[0069] In some technical solutions of the present invention, the fan assembly optionally further includes a base and a limit assembly. The limit assembly is disposed on the base; the second fan blade is disposed on the upper side of the limit assembly and is connected to the limit assembly. The limit assembly restricts the second fan blade from moving toward the limit assembly, and the second fan blade is capable of rotating relative to the limit assembly.

[0070] In this technical solution, the fan assembly also includes a base and a limiting assembly. The limiting assembly is arranged on the base, and the base can provide support for the limiting assembly. At the same time, the base is provided to facilitate the installation of the second fan blade and the limiting assembly. The second fan blade is arranged on the upper side of the limiting assembly and is connected to the limiting assembly. The limiting assembly limits the second fan blade from moving in the direction of the limiting assembly, and the second fan blade can rotate relative to the limiting assembly. The second fan blade is arranged on the upper side of the limiting assembly and is connected to the limiting assembly. The limiting assembly limits the second fan blade from moving in the direction of the limiting assembly, and the second fan blade can rotate relative to the limiting assembly. By setting the limiting assembly to limit the second fan blade, the second fan blade can be prevented from falling off. At the same time, setting the limiting assembly can reduce the contact area of ​​the second fan blade's rotation, thereby reducing friction. When the gas flows through the second fan blade, the rotation effect of the second fan blade can be improved, making it easier for the user to observe the rotation of the second fan blade, enhancing the user's experience, and reducing friction can reduce the wear of the second fan blade, thereby extending the product life.

[0071] In some technical solutions of the present invention, the limiting assembly optionally includes a first matching portion and a first limiting portion. The first limiting portion matches the first matching portion; one of the base body and the second fan blade is connected to the first matching portion; and the other of the base body and the second fan blade is connected to the first limiting portion.

[0072] In this technical solution, the limiting assembly includes a first matching portion and a first limiting portion. The first limiting portion cooperates with the first matching portion to achieve installation between the first limiting portion and the first matching portion. The seat body and one of the second fan blades are connected to the first matching portion. By setting the first matching portion and the first limiting portion to limit the position of the second fan blade, the stability of the second fan blade can be improved and the second fan blade can be prevented from falling off. At the same time, the first limiting portion can be set to contact the second fan blade, while the first matching portion is not in contact with the second fan blade. At the same time, the first matching portion can be set to contact the second fan blade, while the first limiting portion is not in contact with the second fan blade, thereby reducing the contact area between the second fan blade and the first limiting portion and the first matching portion when the second fan blade rotates and reducing friction resistance.

[0073] In some technical solutions of the present invention, optionally, a first gap is provided between the first matching portion and the first limiting portion, and the first gap is arranged circumferentially around the first matching portion.

[0074] In this technical solution, there is a first gap between the first matching part and the first limiting part, and the first gap is arranged circumferentially around the first matching part, reducing the friction between the circumferential side wall of the first matching part and the first limiting part, thereby reducing the resistance of the second fan blade during rotation and improving the smoothness of the second fan blade during rotation.

[0075] In some technical solutions of the present invention, optionally, the fan assembly further includes a cover body, which is disposed on the base body, and the cover body and the base body enclose an installation cavity.

[0076] In this technical solution, the fan assembly also includes a cover body, which is arranged on the base body. The cover body and the base body enclose an installation cavity. The installation cavity can provide space for the installation of the second fan blade and facilitate the production and installation of the second fan blade. The cover body can protect the second fan blade in the installation cavity.

[0077] In some technical solutions of the present invention, the fan assembly optionally further includes a second mating portion and a second limiting portion. The second limiting portion is mated with the second mating portion; one of the cover and the second blade is connected to the second mating portion; and the other of the cover and the second blade is connected to the second limiting portion.

[0078] In this technical solution, the fan assembly also includes a second matching portion and a second limiting portion. The second limiting portion cooperates with the second matching portion to achieve installation between the second limiting portion and the second matching portion. The second limiting portion cooperates with the second matching portion; the cover body and one of the second fan blades are connected to the second matching portion; the cover body and the other of the second fan blades are connected to the second limiting portion. By setting the second matching portion and the second limiting portion to limit the position of the second fan blade, the stability of the second fan blade can be improved and the second fan blade can be prevented from falling off. At the same time, the second limiting portion can be set to contact the second fan blade while the second matching portion does not contact the second fan blade. At the same time, the second matching portion can be set to contact the second fan blade while the second limiting portion does not contact the second fan blade, thereby reducing the contact area between the second fan blade and the second limiting portion and the second matching portion when the second fan blade rotates, thereby reducing frictional resistance.

[0079] In some technical solutions of the present invention, optionally, the air fryer further includes a second heating component, which is disposed in the cooking cavity and arranged axially with the first fan blade along the first driving assembly.

[0080] In this technical solution, the air fryer also includes a second heating component, which is specifically arranged in the cooking cavity. The second heating component is mainly used to heat the air in the cooking cavity, thereby achieving cooking of the food in the cooking cavity.

[0081] The second heating element is placed in the cooking cavity and arranged along the axial direction of the first drive assembly with the first fan blade. This layout helps to ensure that heat can be evenly distributed in the cooking cavity, thereby preventing uneven heating of the food.

[0082] The first fan blade is typically driven by a first drive assembly (such as a motor) to create a circulation of hot air within the cooking cavity. When the second heating element is activated, it heats the surrounding air, which is then blown by the first fan blade to create a circulation. This collaborative approach helps evenly distribute heat to every corner of the cooking cavity.

DETAILED DESCRIPTION

[0093] 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.

[0094] 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.

[0095] Refer to the following Figures 1 to 6 An air fryer 100 according to some embodiments of the present invention is described.

[0096] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments of the present invention, an air fryer 100 is proposed, which includes a main body 102 and an air induced component 136. The main body 102 is provided with a cooking cavity 104 and an exhaust port 110, and the exhaust port 110 is connected to the cooking cavity 104; the air induced component 136 is arranged on the main body 102, and the air induced component 136 is provided with a first air duct 138. The first end 166 of the first air duct 138 is connected to the cooking cavity 104, and the second end 168 of the first air duct 138 extends to the outside of the main body 102; wherein, the gas in the cooking cavity 104 can be discharged from the cooking cavity 104 through the exhaust port 110, and the gas outside the air fryer 100 can enter the cooking cavity 104 through the first air duct 138.

[0097] The air fryer 100 of the present invention includes a main body 102 and an air induction assembly 136. The main body 102 is provided with a cooking cavity 104 for storing and cooking food. The main body 102 is also provided with an exhaust port 110, which is connected to the cooking cavity 104 and is used to exhaust water vapor generated during the cooking process from the cooking cavity 104.

[0098] The air induction assembly 136 is integrated with the main body 102 and is provided with a first air duct 138. A first end 166 of the first air duct 138 is in communication with the cooking cavity 104, and a second end 168 of the first air duct 138 extends outside the main body 102. The first air duct 138 not only allows gas (including water vapor, oil smoke, etc.) within the cooking cavity 104 to be discharged through the exhaust port 110, but also allows fresh air outside the air fryer 100 to enter the cooking cavity 104 through the first air duct 138.

[0099] In related art air fryers, as cooking progresses, moisture and air in the cooking chamber are continuously exhausted. If fresh air is not replenished in a timely manner, the pressure in the chamber will decrease, forming a vacuum-like state, which will seriously affect the further exhaust of moisture and cooking efficiency. The present invention implements an air intake function through the air induction component 136 and the first air duct 138. Gas in the cooking chamber 104 can be discharged from the cooking chamber 104 through the exhaust port 110, and gas outside the air fryer 100 can enter the cooking chamber 104 through the first air duct 138. External air can continuously enter the cooking chamber 104, and fresh air is replenished in the cooking chamber 104 in a timely manner, maintaining a stable pressure, effectively avoiding the occurrence of a vacuum phenomenon, and the air fryer 100 has a high efficiency in exhausting moisture.

[0100] Continuous fresh air replenishment not only maintains sufficient oxygen within cooking chamber 104, ensuring even heating and rapid cooking of food, but also ensures that moisture is promptly removed during the cooking process, preventing condensation on the food surface that affects its taste and appearance. The air circulation driven by induced draft assembly 136, combined with the intake and exhaust design of first air duct 138, forms a highly efficient air exchange system, resulting in more even heat distribution within cooking chamber 104, shortened cooking time, and improved food taste.

[0101] The present application discharges water vapor through the exhaust port 110. The timely discharge of water vapor helps to maintain a dry environment in the cooking cavity 104. The dry environment helps to form a crispy crust on the surface of the food, thereby improving the crispy baking effect.

[0102] As air is exhausted through exhaust port 110, the pressure within cooking cavity 104 decreases, allowing outside air to enter smoothly. Fresh air from outside the air fryer 100 enters cooking cavity 104 through first air duct 138. The removal of moisture and the entry of outside air facilitate air circulation within cooking cavity 104, preventing air pollution and the accumulation of odors. The continuous exchange of fresh air with the air within cooking cavity 104 removes harmful gases and odors generated during cooking, improving the taste and quality of cooked food.

[0103] During the cooking process, aldehydes in food are important components that characterize the aroma of the food. This application optimizes the cooking environment, that is, keeps the cooking cavity 104 dry and introduces air, which can promote the generation and accumulation of aldehydes. Specifically, the aldehydes in food can be increased by 20%, thereby significantly improving the aroma of the food.

[0104] During the cooking process, ingredients may produce harmful substances such as acrylamide and heterocyclic amines. By introducing air, the production of these harmful substances can be reduced. Specifically, the production of harmful substances such as acrylamide and heterocyclic amines can be reduced by 30%, thereby reducing the potential harm of food to the human body. In summary, the air fryer 100 proposed by the present invention allows the cooking chamber 104 to be replenished with air in a timely manner through the air induction component 136 and the first air duct 138. This effectively solves the problem of poor exhaust caused by the reduced pressure in the cooking chamber 104 in the late stage of cooking in traditional air fryers 100. This not only improves cooking efficiency, but also ensures the taste and nutritional value of the food, providing users with a better cooking experience.

[0105] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the air fryer 100 optionally further includes: a first fan blade 116, a first drive assembly 118, and an airflow adjustment component 120. The first fan blade 116 is disposed in the cooking cavity 104; the first drive assembly 118 is connected to the first fan blade 116; the airflow adjustment component 120 is located on one side of the exhaust port 110 and is arranged obliquely relative to the inner wall of the cooking cavity 104; wherein, when the first drive assembly 118 drives the first fan blade 116 to rotate, airflow can be generated in the cooking cavity 104, and the airflow adjustment component 120 can adjust the flow direction and flow rate of at least part of the airflow, so that at least part of the airflow flows out of the cooking cavity 104 through the exhaust port 110.

[0106] In this embodiment, the air fryer 100 further includes a first fan blade 116, a first drive assembly 118, and an airflow regulating component 120. The first fan blade 116 is disposed within the cooking cavity 104, and the first drive assembly 118 is connected to the first fan blade 116. The first drive assembly 118 can drive the first fan blade 116 to rotate, thereby forming an airflow within the cooking cavity 104 and moving water vapor.

[0107] The airflow adjustment component 120 is located on one side of the exhaust port 110 and is arranged at an angle relative to the inner wall of the cooking cavity 104. When the first drive component 118 drives the first fan blade 116 to rotate, airflow can be generated in the cooking cavity 104, and at least part of the airflow can be blocked by the airflow adjustment component 120 and flow out of the cooking cavity 104 through the exhaust port 110.

[0108] When the air fryer 100 is in operation, the high-temperature airflow evaporates the moisture carried by the food while it is being cooked in the cooking chamber 104. The moisture in the food, upon entering the cooking chamber 104, increases the humidity of the air within the cooking chamber 104. The first drive assembly 118 drives the first fan blades 116 to rotate, forming an airflow. At least a portion of the airflow is blocked by the airflow regulating component 120 upon reaching the airflow regulating component 120. The airflow regulating component 120 then directly guides the moisture vapor toward the exhaust port 110. This allows a large amount of moisture vapor to be discharged from the cooking chamber 104 through the guide, without creating a significant pressure difference between the cooking chamber 104 and the outside world, thereby increasing the rate at which moisture vapor is discharged from the cooking chamber 104 overall.

[0109] The airflow regulating component 120 can guide the airflow within the cooking cavity 104 to the exhaust port 110, which then allows the air to exit the cooking cavity 104 through the exhaust port 110. After the air within the cooking cavity 104 is exhausted, the air pressure within the cooking cavity 104 is lower than the ambient air pressure, allowing air to flow more smoothly into the cooking cavity 104. This exhaust of air from the cooking cavity 104 and the smooth entry of outside air ensures a continuous exchange of fresh air with the air within the cooking cavity 104, promoting the formation and accumulation of aldehydes. Specifically, it can increase the aldehyde content in food by 20%, significantly enhancing the food aroma. The airflow regulating component 120 guides the smooth exit of the cooking cavity 104, allowing outside air to enter the cooking cavity 104 smoothly after the pressure within the cooking cavity 104 is reduced. This air exchange can reduce the formation of harmful substances, specifically, by 30% reducing harmful substances such as acrylamide and heterocyclic amines, thereby reducing the potential harm of food to the human body.

[0110] The airflow regulating component 120 guides the airflow to be discharged in time, which helps to maintain a dry environment in the cooking cavity 104. The dry environment helps to form a crispy crust on the surface of the food, thereby improving the crispy baking effect.

[0111] During the cooking process, the humidity in the cooking cavity 104 will change as the food is heated and the water evaporates. The air flow regulating component 120 changes the flow area, thereby changing the air flow rate and improving the cooking effect.

[0112] The airflow control component 120 not only controls the direction and flow of air but also regulates temperature. Specifically, the hot air within the cooking cavity 104 is directed by the airflow control component 120, allowing the hot air to be discharged while allowing cool air from the outside environment to enter the cooking cavity 104. The flow of hot and cool air adjusts the temperature within the cooking cavity 104 to meet adaptability needs, such as cooling the food at the end of cooking or fine-tuning the temperature mid-cooking, to achieve better cooking results.

[0113] Specifically, when cooking is nearing completion, the airflow regulating member 120 is adjusted to increase the rate at which hot air is discharged from the cooking cavity 104, thereby rapidly cooling the food. This helps prevent overcooking of the food and preserves its texture and color. The present invention uses the airflow regulating member 120 to block at least part of the airflow, allowing it to flow out of the cooking cavity 104 through the exhaust port 110. This directs the flow of air within the cooking cavity 104, thereby increasing the rate at which moisture is discharged from the cooking cavity 104 and regulating the humidity within the cooking cavity 104, resulting in a better texture for the cooked food.

[0114] Specifically, the airflow adjustment component 120 includes a baffle or a guide plate.

[0115] Specifically, one end of the baffle is connected to the inner wall of the cooking cavity 104 , and the other end of the baffle extends toward the middle of the cooking cavity 104 and is located on one side of the exhaust port 110 .

[0116] like Figure 1 and Figure 3 As shown, in some embodiments of the present invention, optionally, the airflow adjustment component 120 can rotate relative to the inner wall of the cooking cavity 104 .

[0117] In this embodiment, the airflow adjustment component 120 is rotatable relative to the inner wall of the cooking cavity 104, thereby adjusting the exhaust volume. Specifically, within the cooking cavity 104, air is stirred and flowed by the first fan blade 116. The airflow adjustment component 120 is located on one side of the exhaust port 110 and is arranged at an angle relative to the inner wall of the cooking cavity 104. Some air strikes the deflector plate and is diverted toward the exhaust port 110, while the remaining air, unobstructed by the diversion, remains in the cooking cavity 104 and participates in cooking. The ability of the airflow adjustment component 120 to rotate relative to the inner wall of the cooking cavity 104 varies the amount of air striking the airflow adjustment component 120, achieving efficient adjustment of the exhaust volume.

[0118] Specifically, the airflow adjustment component 120 is rotated relative to the inner wall of the cooking cavity 104. When the angle between the airflow adjustment component 120 and the inner wall of the cooking cavity 104 is larger, the airflow adjustment component 120 has a better air blocking effect, and more air can be allowed to hit the airflow adjustment component 120, thereby achieving an increase in the exhaust volume.

[0119] The airflow adjustment component 120 is rotated relative to the inner wall of the cooking cavity 104, the angle between the airflow adjustment component 120 and the inner wall of the cooking cavity 104 becomes smaller, the contact area between the airflow adjustment component 120 and the flowing air becomes smaller, and less air hits the airflow adjustment component 120 and is directed to the exhaust port 110, thereby achieving a reduction adjustment of the exhaust volume.

[0120] The airflow adjustment member 120 can rotate relative to the inner wall of the cooking cavity 104, enabling efficient and convenient adjustment of the exhaust volume. This allows for simultaneous adjustment of the air intake volume of the first air duct 138. Specifically, when the airflow adjustment member 120 rotates to a position with a larger angle relative to the exhaust port 110, the exhaust volume of the exhaust port 110 increases, thereby increasing the pressure difference between the pressure inside the cooking cavity 104 and the pressure outside the air fryer 100. Due to this larger pressure difference, the air intake volume of the first air duct 138 also increases, thereby adjusting the air intake volume of the first air duct 138. Conversely, when the airflow adjustment member 120 rotates to a position with a smaller angle relative to the exhaust port 110, the exhaust volume of the exhaust port 110 decreases, thereby decreasing the pressure difference between the pressure inside the cooking cavity 104 and the pressure outside the air fryer 100. Due to this smaller pressure difference, the air intake volume of the first air duct 138 also decreases, thereby adjusting the air intake volume of the first air duct 138.

[0121] During the cooking process, the humidity in the cooking cavity 104 changes as the food is heated and the water evaporates. The airflow regulating component 120 rotates to change the flow area, thereby changing the air flow rate.

[0122] Specifically, when the humidity in the cooking cavity 104 is too high, the airflow adjustment component 120 will rotate to increase the flow area, thereby increasing the air flow rate, which helps to discharge excess water vapor in the cooking cavity 104 and reduce the humidity level.

[0123] When the humidity is too low, the airflow adjustment component 120 will rotate to reduce the flow area and reduce the air flow rate, thereby maintaining the humidity in the cooking cavity 104.

[0124] In the present application, the airflow regulating component 120 adjusts the air flow rate out of the cooking cavity 104, changes the pressure within the cooking cavity 104, and allows outside air to smoothly enter the cooking cavity 104. This improves the air quality within the cooking cavity 104. By precisely regulating the humidity and air flow rate within the cooking cavity 104, the airflow regulating component 120 helps reduce the amount of harmful substances generated in food during the cooking process.

[0125] Specifically, high humidity and an oxygen-deficient environment are favorable conditions for the production of harmful substances such as acrylamide. By reducing the humidity in the cooking cavity 104 and increasing the air intake flow rate, the oxygen content and humidity distribution in the cooking cavity 104 can be improved, thereby reducing the amount of harmful substances such as acrylamide generated.

[0126] Heterocyclic amines are another type of harmful substance produced during high-temperature cooking. By adjusting the humidity and air intake in the cooking cavity 104, the cooking temperature can be controlled and the generation of heterocyclic amines can be reduced.

[0127] Specifically, the airflow adjustment component 120 is generally made of a high-temperature-resistant and corrosion-resistant material to ensure stability and durability during the cooking process.

[0128] like Figure 1 and Figure 3 As shown, in some embodiments of the present invention, optionally, the air fryer 100 further includes a connecting rod 126 and a knob 128 , wherein the first end 170 of the connecting rod is connected to the airflow adjustment component 120 ; and the knob 128 is connected to the second end 172 of the connecting rod.

[0129] In this embodiment, the air fryer 100 further includes a connecting rod 126 and a knob 128 , which form a component for adjusting the angle of the airflow adjustment component 120 relative to the inner wall of the cooking cavity 104 .

[0130] The first end 170 of the connecting rod is connected to the airflow adjustment component 120, and the knob 128 is connected to the second end 172 of the connecting rod. By applying force to the knob 128 to rotate the knob 128, the knob 128 can control the connecting rod 126, and then adjust the position of the airflow adjustment component 120, so as to conveniently adjust the angle of the airflow adjustment component 120 relative to the inner wall of the cooking cavity 104, so that the user can conveniently control the exhaust volume during the cooking process through manual control, thereby adjusting the cooking effect of the ingredients.

[0131] Specifically, the user can drive the connecting rod 126 to move by rotating the knob 128. The knob 128 and the second end 172 of the connecting rod are usually connected by a gear mechanism or a threaded mechanism. When the user rotates the knob 128, these mechanisms will convert the rotational motion of the knob 128 into linear motion of the connecting rod 126, thereby driving the airflow adjustment component 120 to rotate relative to the inner wall of the cooking cavity 104.

[0132] The exhaust volume of the air fryer 100 significantly impacts cooking results. Proper exhaust volume ensures even heat distribution throughout the cooking process, achieving optimal cooking results. To adjust the exhaust volume of the air fryer 100, the user simply rotates knob 128. As knob 128 rotates, connecting rod 126 correspondingly drives airflow adjustment component 120 to rotate relative to the inner wall of cooking cavity 104. When knob 128 is rotated in one direction, the angle of airflow adjustment component 120 relative to the inner wall of cooking cavity 104 increases, increasing the airflow directed to exhaust port 110. This ensures smooth airflow, ensures adequate heating of the ingredients, and prevents moisture accumulation within cooking cavity 104. When knob 128 is rotated in the other direction, the angle of airflow adjustment component 120 relative to the inner wall of cooking cavity 104 decreases, reducing exhaust volume and preventing excessive drying or burning of the ingredients.

[0133] The angle of the airflow adjustment component 120 is manually adjusted through the knob 128 and the connecting rod 126, so that the user can make adjustments quickly and accurately according to the current cooking status.

[0134] like Figure 1 As shown, in some embodiments of the present invention, optionally, the knob 128 is disposed on the top of the body 102 and exposed from the body 102 .

[0135] In this embodiment, the knob 128 is set at the top of the main body 102 and is exposed to the main body 102, so that the user can intuitively see the knob 128 and operate it easily. The main function of the knob 128 is to control the movement of the connecting rod 126, and then adjust the rotation angle of the airflow adjustment component 120 connected to the connecting rod 126 to achieve the adjustment of the exhaust volume.

[0136] Specifically, the knob 128 is completely exposed on the top of the body 102 of the air fryer 100 , which makes it easy for the user to intuitively see the knob 128 and also makes it easy for the user to operate the knob 128 .

[0137] Specifically, the surface of the knob 128 is provided with scale lines or marks, and the scale lines and marks can help the user know the current adjustment degree.

[0138] Furthermore, in order to more intuitively display the current exhaust volume, an indicator light or display screen is set next to the knob 128. For example, when the knob 128 is adjusted to different positions, the indicator light can display different colors or brightness, or the display screen can display the specific exhaust volume value.

[0139] Specifically, in order to ensure safe use, a locking mechanism or a protective cover can be provided on the knob 128. When the user is not using the air fryer 100, the knob 128 can be locked or covered with a protective cover to prevent misoperation or children from touching it.

[0140] Specifically, the knob 128 is made of wear-resistant and high-temperature resistant materials to ensure that it will not be damaged or deformed during long-term use.

[0141] The air fryer 100 proposed in the present invention is provided with an air flow regulating component 120 on one side of the exhaust port 110. The air flow regulating component 120 can change its position state. Different position states of the air flow regulating component 120 determine the efficiency of extracting water vapor. The adjustment method can be manual. The present invention uses a connecting rod 126 and a knob 128. By rotating the knob 128, the angle of the air flow regulating component 120 is changed, thereby changing the position state.

[0142] like Figure 6As shown, in some embodiments of the present invention, optionally, the air fryer 100 further includes a second driving assembly 130 , which is connected to the airflow regulating component 120 and can drive the airflow regulating component 120 to rotate relative to the inner wall of the cooking cavity 104 .

[0143] In this technical solution, the air fryer 100 also includes a second drive assembly 130, which is connected to the airflow adjustment component 120. The air fryer 100 is provided with a second drive assembly 130, which is connected to the airflow adjustment component 120 and can drive the airflow adjustment component 120 to rotate relative to the inner wall of the cooking cavity 104, providing users with a more convenient and accurate exhaust volume adjustment method.

[0144] Specifically, the second drive component 130 is an electric drive device, such as a motor and a transmission structure. The second drive component 130 can receive instructions from a control panel or an intelligent control system, thereby accurately controlling the rotation angle of the airflow adjustment component 120. The air fryer 100 can adjust the exhaust volume to meet the needs of different ingredients and cooking modes.

[0145] like Figure 6 As shown, in some embodiments of the present invention, optionally, the air fryer 100 further includes a humidity detection component 132 and a control component 134. The humidity detection component 132 can detect the humidity in the cooking cavity 104; the control component 134 is disposed in the body 102, electrically connected to the second drive component 130, and electrically connected to the humidity detection component 132. The control component 134 can control the second drive component 130 to drive the airflow adjustment component 120 to rotate according to the humidity in the cooking cavity 104.

[0146] In this embodiment, the air fryer 100 further includes a humidity detection component 132 and a control assembly 134 . The humidity detection component 132 is installed in the cooking cavity 104 of the air fryer 100 for detecting the humidity level in the cooking cavity 104 in real time.

[0147] Specifically, the humidity detection component 132 includes a capacitive humidity sensor or a resistive humidity sensor.

[0148] The control assembly 134 is disposed within the main body 102 and is electrically connected to the second drive assembly 130 and the humidity detection component 132. The control assembly 134 controls the second drive assembly 130 to rotate the airflow control component 120 based on the humidity within the cooking cavity 104. When the air fryer 100 begins operation, the humidity detection component 132 begins detecting the humidity level within the cooking cavity 104. The control assembly 134 reads the data transmitted by the humidity detection component 132 and compares it with a preset humidity threshold. Based on the comparison result of the humidity data with the threshold, the control assembly 134 sends a command to the second drive assembly 130 to control the rotation of the airflow control component 120.

[0149] If the humidity is too high, the control assembly 134 controls the second drive assembly 130 to rotate the airflow adjustment member 120 to a larger angle position to increase air circulation within the cooking cavity 104, thereby reducing the humidity. Conversely, if the humidity is too low, the control assembly 134 may command the airflow adjustment member 120 to rotate to a smaller angle position to maintain the humidity within the cooking cavity 104.

[0150] Such a design allows the air fryer 100 to more intelligently adjust the humidity in the cooking cavity 104 during the cooking process, thereby improving the cooking effect of the ingredients.

[0151] like Figure 4 As shown, in some embodiments of the present invention, optionally, the direction of movement of the airflow in the cooking cavity 104 (eg Figure 4 In the direction indicated by the arrow D in the middle), the first side 122 of the airflow adjustment component 120 is located at the leeward side of the exhaust port 110, and the second side 124 of the airflow adjustment component 120 extends toward the upwind side of the exhaust port 110.

[0152] In this embodiment, the present application positions the airflow regulating member 120 based on the direction of airflow within the cooking cavity 104. Specifically, the first side 122 of the airflow regulating member 120 is located downwind of the exhaust port 110, and the second side 124 of the airflow regulating member 120 extends upwind of the exhaust port 110. When the air fryer 100 is in operation, hot air circulates within the cooking cavity 104, typically being heated from the bottom or sides and blown toward the food, then rising and passing over the surface of the food before being exhausted through the exhaust port 110. In this design, the first side 122 of the airflow regulating member 120 is located near the exhaust port 110, while the second side 124 faces the source of the hot air.

[0153] The airflow regulating member 120 is located on the airflow path, and it can effectively control the flow direction and speed of the airflow. By adjusting the angle of the airflow regulating member 120, the user can more accurately control the humidity in the cooking cavity 104, thereby achieving a more ideal cooking effect.

[0154] When the airflow regulating member 120 is located at the downwind side of the exhaust port 110 , it can prevent hot air from being discharged through the exhaust port 110 too quickly, thereby ensuring that sufficient heat and humidity are maintained in the cooking cavity 104 .

[0155] By adjusting the position and angle of the airflow regulating component 120 , the hot air can be distributed more evenly in the cooking cavity 104 , thereby ensuring that all parts of the food can be adequately heated and cooked.

[0156] like Figure 2 As shown, in some embodiments of the present invention, optionally, a second air duct 106 is provided in the cooking cavity 104 , and the second air duct 106 is located at the second end of the first air duct 138 , extends along the flow direction of the airflow in the cooking cavity 104 , and is connected to the first air duct 138 .

[0157] In this embodiment,

[0158] The cooking cavity 104 is provided with a second air duct 106, which is located at the second end of the first air duct 138 and extends along the air flow direction in the cooking cavity 104 and communicates with the first air duct 138. The second air duct 106 is a flow channel design inside the cooking cavity 104 for guiding air flow.

[0159] When the air fryer 100 is in operation, the air in the cooking cavity 104 is heated and circulated. Due to the design of the internal flow channel of the cooking cavity 104, that is, the second air duct 106, the air flow velocity in the second air duct 106 increases. According to Bernoulli's principle, the pressure decreases where the flow velocity increases.

[0160] When the pressure inside cooking cavity 104 drops, a pressure difference forms with the outside air. Due to the high pressure of the outside air, air is forced through first air duct 138 into second air duct 106, and ultimately into cooking cavity 104. The design of air induction assembly 136 significantly enhances air flow within cooking cavity 104, ensuring more even heating of ingredients and improving cooking results. Introducing outside air through a natural pressure difference eliminates the need for additional energy consumption, resulting in energy-saving and high efficiency.

[0161] Specifically, if Figure 2 As shown, hot air enters the second air duct 106 and air enters the first air duct 138 , and is discharged from the air outlet 108 after mixing.

[0162] like Figure 3As shown, when the air fryer 100 is in operation, cooking air (flow rate Q0) enters the cooking chamber 104, that is, enters the second air duct 106. The high-speed body flow causes a pressure difference with the outside air, causing the outside air (flow rate Q1) to be pressed into the second air duct 106. The air flow rate output from the outlet of the second air duct 106 is Q0+Q1. After being rectified by the second air duct 106, the streamline of the outlet of the second air duct 106 flows out at a substantially perpendicular angle to the outlet. Part of the air output from the second air duct 106 (air carrying water vapor) The air that hits the air flow regulating component 120 is guided out (flow rate Q2), and the remaining air that is not blocked by the air flow regulating component 120 (the air entering the cooking cavity) (flow rate Q3) continues to participate in cooking in the cooking cavity 104 (flow conservation equation: Q0+Q1=Q2+Q3). ​​By changing the position angle of the air flow regulating component 120, the amount (Q2) of air (air carrying water vapor) that hits the air flow regulating component 120 can be changed. The more it hits, the more air is discharged from the exhaust port 110.

[0163] As for water vapor, a large amount of water vapor is generated during the cooking process of ingredients in the cooking cavity 104, causing the water vapor concentration in the cooking cavity 104 to be significantly higher than that in the outside air. When air (flow rate Q1) enters, the water vapor diffuses from the high-concentration air in the cooking cavity 104 to the low-concentration air (or a mixture of dry air and moist air). When the cooking air is discharged from the cooking cavity 104 through the airflow adjustment component 120, the discharged air is mixed with air with a high water vapor concentration. From the perspective of the entire cooking cavity 104, the incoming air (flow rate Q1) is dry, and the discharged air (air carrying water vapor) (flow rate Q2) is moist. Therefore, the moisture in the cooking cavity 104 is continuously discharged and reduced, ultimately achieving a drying effect.

[0164] The conventional air fryer 100 with a guide plate will be affected by the internal pressure of the cooking chamber 104 when draining water vapor, and the effect will be greatly weakened in the later stage of cooking (the water vapor removal process will take away air, and it cannot be drawn into a "vacuum" without air replenishment, and eventually the water vapor removal will stop). The utility model solves the problem of no exhaust in the later stage similar to "vacuum". The air intake function continuously brings fresh oxygen content to the cooking chamber 104, improves the cooking effect, and continuously replenishes the exhausted air, so that the entire cooking process can efficiently remove water vapor without the "vacuum" phenomenon; in addition, by adjusting the angle of the guide plate, the speed of water vapor removal can be selected; (increase oxygen concentration + water vapor removal option).

[0165] like Figure 3 As shown, in some embodiments of the present invention, optionally, the air fryer 100 further includes an air duct plate 112, which is connected to the main body 102, and the air duct plate 112 and the inner wall of the main body 102 form a second air duct 106; or the air fryer 100 further includes a second pipe 114, and the second pipe 114 is provided with a second air duct 106.

[0166] In this embodiment, on the one hand, the air fryer 100 further includes an air duct plate 112, which is connected to the main body 102. The air duct plate 112 and the inner wall of the main body 102 enclose a second air duct 106 to guide and control the flow path of air in the cooking cavity 104 during the cooking process.

[0167] On the other hand, the air fryer 100 further includes a second conduit 114, which is provided with a second air duct 106 for guiding and controlling the flow of air during the cooking process. The second conduit 114 is directly integrated into the body 102 of the air fryer 100, making the structure more compact.

[0168] like Figure 2 and Figure 4 As shown, in some embodiments of the present invention, optionally, the air outlet end 108 of the second air duct 106 faces the airflow adjustment component 120 .

[0169] In this embodiment, the air outlet end 108 of the second air duct 106 faces the air flow regulating member 120. The airflow from the second air duct 106 first encounters the air flow regulating member 120. The amount of air exhausted from the cooking cavity 104 can be controlled by adjusting the rotation angle of the air flow regulating member 120. This design can be flexibly adjusted to meet different cooking needs to achieve the best cooking effect.

[0170] like Figure 1 、 Figure 2 and Figure 4 As shown, in some embodiments of the present invention, optionally, the air fryer 100 further includes a first heating component 140 , and the first heating component 140 is disposed in the first air duct 138 or the second air duct 106 .

[0171] In this embodiment, the air fryer 100 further includes a first heating component 140 , which is an important component of the air fryer 100 and is used to increase the intake air temperature. Specifically, the first heating component 140 is disposed in the first air duct 138 or the second air duct 106 .

[0172] The first heating component 140 is disposed in the air intake system of the air fryer 100 , that is, the first heating component 140 is disposed in the first air duct 138 , or the first heating component 140 is disposed in the second air duct 106 , to ensure that the air can be effectively heated when passing through.

[0173] The main function of the first heating component 140 is to increase the temperature of the intake air. When the air fryer 100 starts working, fresh air will pass through the first air duct 138 and the second air duct 106. During this process, the first heating component 140 will heat the air to a temperature suitable for cooking. This heating process helps to ensure that the ingredients can be heated evenly, thereby achieving better cooking results.

[0174] In addition, the first heating component 140 is disposed in the first air duct 138 or the second air duct 106 , so that the first heating component 140 can generate heat radiation to the cooking cavity 104 , thereby improving the cooking effect of the air fryer 100 .

[0175] Specifically, the first heating element 140 is an electric heater. When current passes through the electric heater, the electric heater generates heat, which is transferred to the air in contact with the electric heater, thereby increasing the temperature of the air. In this way, heat can be continuously provided to the air to ensure that the air temperature is suitable.

[0176] like Figure 2 As shown, in some embodiments of the present invention, optionally, the cross-sectional area of ​​the second air duct 106 decreases from both ends of the second air duct 106 toward the location of the first air duct 138 .

[0177] In this embodiment, the shape of the second air duct 106 is limited, and the cross-sectional area of ​​the second air duct 106 decreases from both ends of the second air duct 106 to the position of the first air duct 138, which helps to accelerate the airflow and increase the intake volume of the intake air.

[0178] According to Bernoulli's principle, when a fluid (such as air) flows in a pipe, if the cross-sectional area of ​​the pipe gradually decreases, the velocity of the fluid will increase, while the pressure will decrease. This is because when a fluid passes through a pipe with a smaller cross-sectional area, due to the law of conservation of volume, the flow rate must increase to maintain the flow rate constant. This increase in flow rate causes the pressure to decrease because when kinetic energy increases, potential energy (in this case, pressure) is converted into kinetic energy. When the cross-sectional area of ​​the second air duct 106 gradually decreases, the hot air in the cooking cavity 104 will be accelerated when passing through the second air duct 106. This accelerated airflow helps to better stir and circulate the air in the cooking cavity 104, ensuring that the food is heated more evenly.

[0179] As the cross-sectional area of ​​second air duct 106 gradually decreases and the airflow velocity increases, a negative pressure area is created at the entrance of second air duct 106 (i.e., where air enters). This negative pressure area draws more outside air into second air duct 106, thereby increasing the air intake. This replenishes the hot air consumed during cooking and maintains a stable temperature within cooking cavity 104. Furthermore, the incoming air removes cooking fumes and odors, maintaining a fresh cooking environment.

[0180] like Figure 1 and Figure 5 As shown, in some embodiments of the present invention, optionally, the air fryer 100 further includes a fan assembly 142, which is disposed at the second end of the first air duct 138 and exposed to the body 102, and the fan assembly 142 includes a second fan blade 144, and the gas flow in the first air duct 138 can drive the second fan blade 144 to rotate.

[0181] In this embodiment, the air fryer 100 further includes a fan assembly 142. The fan assembly 142 is disposed at the second end of the first air duct 138 and is exposed to the body 102. The fan assembly 142 includes second blades 144. The gas flow in the first air duct 138 can drive the second blades 144 to rotate.

[0182] Specifically, Figure 5 For Figure 1 A partial enlarged view after planing at point A.

[0183] The fan assembly 142 is disposed at the second end of the first air duct 138 and is exposed from the body 102. Exposing the fan assembly 142 from the body 102 allows visualization of the internal operation of the fan assembly 142. The user can observe the rotation of the second fan blades 144 through the exposed fan assembly 142, thereby determining the air intake status of the cooking cavity 104. The exposed fan assembly 142 is provided with a light-transmissive cover 156, allowing intuitive observation of the rotation of the second fan blades 144, thereby improving the cooking effect of the ingredients and enhancing the user experience.

[0184] Furthermore, the fan assembly 142 may be exposed outside the body 102 in a specific manner: the second fan blades 144 may be placed outside the body 102, the second fan blades 144 may be arranged inside the body 102, or a portion of the second fan blades 144 may be arranged outside the body 102 and another portion of the second fan blades 144 may be arranged inside the body 102. The second fan blades 144 may be positioned so as to facilitate the user's observation of the rotation of the second fan blades 144. The fan blade portion of the second fan blades 144 may be selected in a color with high color differentiation, making it easier for the user to observe the rotation of the second fan blades 144 and providing better feedback to the user on the operating status of the air fryer 100.

[0185] like Figure 1 and Figure 5As shown, in some embodiments of the present invention, the fan assembly 142 optionally further includes a base 146 and a stop assembly 148. The stop assembly 148 is disposed on the base 146; the second fan blade 144 is disposed on the upper side of the stop assembly 148 and is connected to the stop assembly 148. The stop assembly 148 restricts the second fan blade 144 from moving toward the stop assembly 148, and the second fan blade 144 can rotate relative to the stop assembly 148.

[0186] In this embodiment, the fan assembly 142 also includes a base 146 and a limiting assembly 148. The limiting assembly 148 is arranged on the base 146, and the base 146 can provide support for the limiting assembly 148. At the same time, the base 146 is provided to facilitate the installation of the second fan blade 144 and the limiting assembly 148. The second fan blade 144 is arranged on the upper side of the limiting assembly 148 and is connected to the limiting assembly 148. The limiting assembly 148 limits the second fan blade 144 from moving in the direction of the limiting assembly 148, and the second fan blade 144 can rotate relative to the limiting assembly 148. The second fan blade 144 is arranged on the upper side of the limiting assembly 148 and is connected to the limiting assembly 148. The limiting assembly 148 limits the second fan blade 144 from moving in the direction of the limiting assembly 148, and the second fan blade 144 can rotate relative to the limiting assembly 148. By setting the limiting component 148 to limit the second fan blade 144, the second fan blade 144 can be prevented from falling off. At the same time, setting the limiting component 148 can reduce the contact area of ​​the second fan blade 144 during rotation, thereby reducing friction. When the gas flows through the second fan blade 144, the rotation effect of the second fan blade 144 can be improved, which makes it easier for the user to observe the rotation of the second fan blade 144 and enhance the user experience. At the same time, reducing friction can reduce the wear of the second fan blade 144, thereby extending the product life.

[0187] like Figure 1 and Figure 5 As shown, in some embodiments of the present invention, the limiting assembly 148 optionally includes a first matching portion 150 and a first limiting portion 152. The first limiting portion 152 matches the first matching portion 150; one of the base 146 and the second blade 144 is connected to the first matching portion 150; and the other of the base 146 and the second blade 144 is connected to the first limiting portion 152.

[0188] In this embodiment, the limiting assembly 148 includes a first matching portion 150 and a first limiting portion 152. The first limiting portion 152 cooperates with the first matching portion 150 to achieve installation between the first limiting portion 152 and the first matching portion 150. The seat 146 and one of the second fan blades 144 are connected to the first matching portion 150. By setting the first matching portion 150 and the first limiting portion 152 to limit the position of the second fan blade 144, the stability of the second fan blade 144 can be improved and the second fan blade 144 can be prevented from falling off. At the same time, the first limiting portion 152 can be set to contact the second fan blade 144, while the first matching portion 150 is not in contact with the second fan blade 144. At the same time, the first matching portion 150 can be set to contact the second fan blade 144, while the first limiting portion 152 is not in contact with the second fan blade 144, thereby reducing the contact area between the second fan blade 144 and the first limiting portion 152 and the first matching portion 150 when the second fan blade 144 rotates, thereby reducing friction resistance.

[0189] like Figure 1 and Figure 5 As shown, in some embodiments of the present invention, optionally, a first gap 154 ​​is provided between the first matching portion 150 and the first limiting portion 152 , and the first gap 154 ​​is arranged around the circumference of the first matching portion 150 .

[0190] In this embodiment, a first gap 154 ​​is defined between the first matching portion 150 and the first limiting portion 152, and the first gap 154 ​​surrounds the circumference of the first matching portion 150 (eg, Figure 5 The arrangement is arranged in the direction shown by B in the figure to reduce the friction between the circumferential side wall of the first matching portion 150 and the first limiting portion 152, thereby reducing the resistance of the second fan blade 144 during rotation and improving the smoothness of the second fan blade 144 during rotation.

[0191] like Figure 1 and Figure 5 As shown, in some embodiments of the present invention, optionally, the fan assembly 142 further includes a cover 156 , which is disposed on the base 146 , and the cover 156 and the base 146 enclose a mounting cavity 158 .

[0192] In this embodiment, the fan assembly 142 also includes a cover body 156, which is covered on the base body 146. The cover body 156 and the base body 146 enclose an installation cavity 158. The installation cavity 158 can provide space for the installation of the second fan blade 144, and at the same time facilitate the production and installation of the second fan blade 144. The cover body 156 can protect the second fan blade 144 in the installation cavity 158.

[0193] like Figure 1 and Figure 5As shown, in some embodiments of the present invention, the fan assembly 142 optionally further includes a second mating portion 160 and a second limiting portion 162. The second limiting portion 162 is mated with the second mating portion 160; one of the cover 156 and the second fan blade 144 is connected to the second mating portion 160; and the other of the cover 156 and the second fan blade 144 is connected to the second limiting portion 162.

[0194] In this embodiment, the fan assembly 142 further includes a second mating portion 160 and a second limiting portion 162. The second limiting portion 162 mates with the second mating portion 160 to achieve installation between the second limiting portion 162 and the second mating portion 160. The second limiting portion 162 mates with the second mating portion 160; one of the cover 156 and the second blade 144 is connected to the second mating portion 160; and the other of the cover 156 and the second blade 144 is connected to the second limiting portion 162. By setting the second matching portion 160 and the second limiting portion 162 to limit the position of the second fan blade 144, the stability of the second fan blade 144 can be improved to prevent the second fan blade 144 from falling off. At the same time, the second limiting portion 162 can be set to contact the second fan blade 144, while the second matching portion 160 is not in contact with the second fan blade 144. At the same time, the second matching portion 160 can be set to contact the second fan blade 144, while the second limiting portion 162 is not in contact with the second fan blade 144, thereby reducing the contact area between the second fan blade 144 and the second limiting portion 162 and the second matching portion 160 when the second fan blade 144 rotates, thereby reducing friction resistance.

[0195] like Figure 1 and Figure 5 As shown, in some embodiments of the present invention, optionally, the air fryer 100 further includes a second heating component 164, which is disposed in the cooking cavity 104 and is arranged along the axial direction of the first drive assembly 118 ( Figure 1 Arrange in the direction shown by C).

[0196] In this embodiment, the air fryer 100 further includes a second heating component 164 , which is specifically disposed in the cooking cavity 104 . The second heating component 164 is mainly used to heat the air in the cooking cavity 104 , thereby achieving cooking of the food in the cooking cavity 104 .

[0197] The second heating element 164 is placed in the cooking cavity 104 and arranged along the axial direction of the first driving assembly 118 with the first fan blade 116. Such a layout helps to ensure that heat can be evenly distributed in the cooking cavity 104, thereby preventing uneven heating of the food.

[0198] First fan blades 116 are typically driven by a first drive assembly 118 (e.g., a motor) to create a circulation of heated air within cooking cavity 104. When second heating element 164 is in operation, it heats the surrounding air, which is then blown by first fan blades 116, creating a circulation. This coordinated operation helps evenly distribute heat to every corner of cooking cavity 104.
