Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and more particularly, to an air fryer. Background Art

[0002] At present, for an air fryer driven by electromagnetic heating, since the fan blade generates heat by itself, the fan blade is generally thick and heavy. Therefore, the inertia of the fan blade is large. After the machine stops or the power is cut off, the fan blade will continue to rotate for a long time, and there may be a situation where a user touches it and gets hurt.

[0003] In the related art, a safety protection cover is added outside the fan blade for shielding. However, dirt such as oil is likely to accumulate inside the safety protection cover, which affects hygiene after long-term use. Summary of the Utility Model

[0004] An embodiment of the utility model aims to solve at least one of the technical problems existing in the prior art.

[0005] For this reason, a first aspect of an embodiment of the utility model provides an air fryer.

[0006] In view of this, according to a first aspect of an embodiment of the utility model, there is provided an air fryer, which includes: a body provided with a cooking cavity; a hot air assembly provided in the body for delivering hot air to the cooking cavity; a protective cover provided in the cooking cavity and covering one side of the hot air assembly facing the cooking cavity, and a ventilation surface is provided on one side of the protective cover facing the hot air assembly, and along the height direction of the body, the ventilation surface faces the hot air assembly; wherein at least a part of the ventilation surface is an inclined surface.

[0007] The air fryer provided by the embodiment of the utility model includes a body, a hot air assembly and a protective cover. Specifically, the body is provided with a cooking cavity, and the hot air assembly can deliver hot air into the cooking cavity, and the hot air circulates in the cooking cavity, thereby heating and cooking the food materials in the cooking cavity.

[0008] It can be understood that the hot air assembly includes blades that can rotate in the cooking cavity to form a hot air circulation in the cooking cavity. When the air fryer stops or the power is cut off, due to inertia, the blades will continue to rotate for a certain period of time, and there is a risk that a user may be injured by accidentally touching the rotating blades.

[0009] The protective cover covers one side of the hot air assembly facing the cooking cavity, that is, shields the hot air assembly that generates hot air, thereby effectively avoiding the problem that a user may be injured by accidentally touching the hot air assembly with a high temperature or the rotating blades during the operation of the air fryer, and improving the safety of using the air fryer.

[0010] It can be understood that during the operation of the air fryer, under the action of the hot air component, the air in the cooking cavity enters the protective cover and then flows out through the protective cover, forming a hot air circulation. During this process, impurities such as oil stains are easily attached to the protective cover, especially on the side of the protective cover facing the hot air component, which is not convenient for cleaning. Bacteria are likely to breed after long-term use, affecting hygiene.

[0011] A ventilation surface is provided on the side of the protective cover facing the hot air component. Along the height direction of the machine body, the ventilation surface is opposite to the hot air component, and at least a part of the ventilation surface is an inclined surface. That is to say, at least a part of the side of the protective cover facing the hot air component is set as an inclined surface, so that after the oil stains entering the protective cover drip onto the ventilation surface, they can flow along the ventilation surface and be discharged. Specifically, the dirt can flow to a position where it is easy to clean, or the dirt flows to the communication port and is discharged, which is beneficial to reducing the accumulation of oil stains on the inner surface of the protective cover, reducing the cleaning difficulty, solving the problem that the inner surface of the protective cover is not easy to clean and is prone to accumulate oil stains, and is prone to breed bacteria after long-term use, improving the cleaning effect of the air fryer, and further improving the user experience.

[0012] Optionally, the ventilation surface is an overall inclined inclined surface. Or, the ventilation surface is an inclined surface formed by protruding outward from the center. Or, the ventilation surface is an inclined surface formed by concave inward from the center. It can be specifically set according to actual needs. As long as the ventilation surface forms an inclined surface with a certain height difference in the height direction of the machine body.

[0013] Optionally, the angle α between the inclined surface and the horizontal plane satisfies 2° ≤ α ≤ 8°. It can be understood that if the angle between the inclined surface and the horizontal plane is too small, that is, α is less than 2°, it is not conducive to the flow of oil stains on the inclined surface. After long-term use, too much oil is likely to accumulate on the ventilation surface, affecting hygiene.

[0014] If the angle between the inclined surface and the horizontal plane is too large, that is, α is greater than 8°, in the case where the ventilation surface is an inclined surface concave inward from the center, the too large angle makes the distance between the ventilation surface and the hot air component too close, and interference is likely to occur during the rotation of the blades of the hot air component, increasing the noise during the operation of the air fryer. In the case where the ventilation surface is an inclined surface protruding outward from the center, the too large angle makes the protective cover too high, resulting in a large space occupied by the protective cover in the cooking cavity, that is, occupying the baking space.

[0015] By limiting the angle between the inclined surface and the horizontal plane to between 2° and 8°, it is possible to reduce the accumulation of oil stains on the ventilation surface while reducing the space occupied by the protective cover in the cooking cavity, improving the user experience.

[0016] In addition, the air fryer provided according to the above technical solution of the present invention further has the following additional technical features:

[0017] In some technical solutions, optionally, the ventilation surface includes a first end and a second end. The second end is disposed closer to the central axis of the hot air component than the first end. Along the height direction of the body, the first end is higher than the second end; the protective cover is provided with a communication port that communicates the ventilation surface and the cooking cavity, and the communication port is disposed close to the second end.

[0018] In this technical solution, it is defined that the ventilation surface includes a first end and a second end. The second end is disposed closer to the central axis of the hot air component than the first end. That is to say, the second end is close to the central position of the ventilation surface, and the first end is close to the edge position of the ventilation surface. Along the height direction of the body, the first end is higher than the second end. That is to say, the central position of the protective cover is low and the edge position is high, so that the ventilation surface is formed into an inclined surface.

That is to say, the communication port is close to the center of the ventilation surface and is located at a low position. The communication port communicates the cooking cavity and the ventilation surface. That is to say, after the oil stains and the like sucked into the protective cover drip onto the inclined surface, they can flow along the inclined surface to the communication port and be discharged outside the protective cover through the communication port, further reducing the accumulation of oil stains in the protective cover, reducing the cleaning difficulty of the protective cover, and improving the cleaning effect of the protective cover.

[0020] It can be understood that the oil stains in the protective cover are discharged into the cooking cavity through the communication port.

When the protective cover is removed, the oil stains collected in the oil storage structure are centrally cleaned, which is beneficial to reducing the cleaning difficulty and improving the cleaning effect of the protective cover.

[0027] Moreover, since the oil storage structure separates the ventilation surface and the communication port, it can prevent the oil stains on the ventilation surface from entering the cooking cavity through the communication port and contaminating the food materials. At this time, the communication port is used for ventilation, which is beneficial to strengthening the air flow circulation in the cooking cavity and thus improving the cooking effect.

[0028] In some technical solutions, optionally, the oil storage structure is arranged around the communication port.

That is to say, the second end is close to the central position of the ventilation surface, and the first end is close to the edge position of the ventilation surface. Along the height direction of the machine body, the first end is lower than the second end.

When the protective cover is removed, it is convenient to clean the oil stains and improve the cleaning effect.

[0043] Moreover, when the protective cover includes a communication port, since the oil baffle separates the ventilation surface and the communication port, it can also prevent the oil stains on the ventilation surface from entering the cooking cavity through the communication port and contaminating the food materials. At this time, the communication port is used for ventilation, which is beneficial to strengthening the air flow circulation in the cooking cavity and then improving the cooking effect.

[0049] A plurality of first ventilation openings are arranged on the first cover body. Specifically, along the height direction of the machine body, each first ventilation opening penetrates through the first cover body. That is to say, each first ventilation opening communicates the ventilation surface and the cooking cavity, so that the air in the cooking cavity can enter the protective cover through the plurality of first ventilation openings.

Specifically, when the electromagnetic component is powered on, at least part of the blade with magnetic conductivity can generate heat, thereby heating the surrounding air. At the same time, driven by the motor, the blade rotates in the cooking cavity and takes away the heat to form a hot air flow, dissipating the heat generated by the blade.

[0066] Specifically, when the electromagnetic component is powered on, it can generate an alternating magnetic field. Under the action of the alternating magnetic field, the magnetic conductive blades will generate heat. Through the interaction between the electromagnetic component and the magnetic conductive blades, the temperature of the blades can rise rapidly within a short time. At the same time, when the blades rotate, hot air currents are quickly generated in the cooking cavity.

Detailed implementation manners

[0079] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0080] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0081] The following refers to Figures 1 to 8 to describe the air fryer 100 provided according to some embodiments of the present invention.

[0082] In an embodiment according to the present application, as Figure 1 , Figure 2 and Figure 3 shown, an air fryer 100 is proposed. The air fryer 100 includes: a body 110, the body 110 is provided with a cooking cavity 111; a hot air assembly 120, arranged in the body 110, for delivering hot air to the cooking cavity 111; a protective cover 130, arranged in the cooking cavity 111 and covering the side of the hot air assembly 120 facing the cooking cavity 111. The side of the protective cover 130 facing the hot air assembly 120 is provided with a ventilation surface 131. Along the height direction of the body 110, the ventilation surface 131 faces the hot air assembly 120; wherein, at least a part of the ventilation surface 131 is an inclined surface.

[0083] The air fryer 100 provided by the embodiment of the present invention includes a body 110, a hot air assembly 120 and a protective cover 130. Specifically, the body 110 is provided with a cooking cavity 111, the hot air assembly 120 can deliver hot air into the cooking cavity 111, and the hot air circulates in the cooking cavity 111, thereby heating and cooking the food in the cooking cavity 111.

[0084] It can be understood that the hot air component 120 includes blades 122 which can rotate within the cooking cavity 111 to form a hot air circulation within the cooking cavity 111. When the air fryer 100 stops or is powered off, due to inertia, the blades 122 will continue to rotate for a certain period of time, and there is a risk that the user may accidentally touch the rotating blades 122 and get their hands injured.

[0085] The protective cover 130 is disposed on the side of the hot air component 120 facing the cooking cavity 111, that is, it shields the hot air component 120 that generates hot air, thereby effectively preventing the user from getting their hands injured during the operation of the air fryer 100 due to accidentally touching the hot air component 120 with a relatively high temperature or the rotating blades 122, and improving the safety of using the air fryer 100.

[0086] It can be understood that during the operation of the air fryer 100, under the action of the hot air component 120, the air in the cooking cavity 111 enters the protective cover 130 and then flows out through the protective cover 130 to form a hot air circulation. During this process, impurities such as oil stains are easily attached to the protective cover 130, especially on the side surface of the protective cover 130 facing the hot air component 120, which is not convenient for cleaning, and bacteria are likely to breed after long-term use, affecting hygiene.

[0087] A ventilation surface 131 is provided on the side of the protective cover 130 facing the hot air component 120. Along the height direction of the machine body 110, the ventilation surface 131 is opposite to the hot air component 120, and at least a part of the ventilation surface 131 is an inclined surface. That is to say, at least a part of the side surface of the protective cover 130 facing the hot air component 120 is set as an inclined surface, so that after the oil stains entering the protective cover 130 drop onto the ventilation surface 131, they can flow out along the ventilation surface 131. Specifically, the dirt can flow to a position where it is easy to clean, or the dirt flows to the communication port 132 and is discharged, which is beneficial to reducing the accumulation of oil stains on the inner surface of the protective cover 130, reducing the cleaning difficulty, solving the problem that the inner surface of the protective cover 130 is not easy to clean and is prone to accumulate oil stains, and is likely to breed bacteria after long-term use, improving the cleaning effect of the air fryer 100, and further improving the user experience.

[0088] Optionally, the ventilation surface 131 is an overall inclined surface. Or, the ventilation surface 131 is an inclined surface formed by protruding outward from the center. Or, the ventilation surface 131 is an inclined surface formed by concave inward from the center. It can be specifically set according to actual needs. As long as the ventilation surface 131 forms an inclined surface with a certain height difference in the height direction of the machine body 110.

[0089] As Figure 3 shown, in some embodiments, optionally, the angle α between the inclined surface and the horizontal plane satisfies 2° ≤ α ≤ 8°.

[0090] In this embodiment, the value range of the inclination angle of the inclined surface is defined. Specifically, the included angle between the inclined surface and the horizontal plane is between 2° and 8°.

[0091] It can be understood that if the included angle between the inclined surface and the horizontal plane is too small, that is, α is less than 2°, it is not conducive to the flow of oil stains on the inclined surface. After long-term use, too much oil is likely to accumulate on the ventilation surface 131, affecting hygiene.

[0092] If the included angle between the inclined surface and the horizontal plane is too large, that is, α is greater than 8°, in the case where the ventilation surface 131 is an inclined surface that is concave inward with the center as the center, the too large included angle makes the distance between the ventilation surface 131 and the hot air component 120 too close, and interference is likely to occur during the rotation of the blades 122 of the hot air component 120, increasing the noise during the operation of the air fryer 100. In the case where the ventilation surface 131 is an inclined surface that is convex outward with the center as the center, the too large included angle makes the protective cover 130 too high, resulting in a large space occupied by the protective cover 130 in the cooking cavity 111, that is, occupying the baking space.

[0093] By limiting the included angle between the inclined surface and the horizontal plane to be between 2° and 8°, it is possible to reduce the accumulation of oil stains on the ventilation surface 131 while reducing the space occupied by the protective cover 130 in the cooking cavity 111, improving the user experience.

[0094] Such as Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, optionally, the ventilation surface 131 includes a first end 133 and a second end 134. The second end 134 is arranged closer to the central axis of the hot air component 120 than the first end 133. Along the height direction of the body 110, the first end 133 is higher than the second end 134; the protective cover 130 is provided with a communication port 132, and the communication port 132 communicates the ventilation surface 131 and the cooking cavity 111, and the communication port 132 is arranged close to the second end 134.

[0095] In this embodiment, it is defined that the ventilation surface 131 includes a first end 133 and a second end 134. The second end 134 is arranged closer to the central axis of the hot air component 120 than the first end 133. That is to say, the second end 134 is close to the center position of the ventilation surface 131, and the first end 133 is close to the edge position of the ventilation surface 131. Along the height direction of the body 110, the first end 133 is higher than the second end 134. That is to say, the center position of the protective cover 130 is low and the edge position is high, so that the ventilation surface 131 is formed into an inclined surface.

[0096] The protective cover 130 is also provided with a communication port 132, which is arranged close to the second end 134. That is to say, the communication port 132 is arranged close to the center of the ventilation surface 131 and is located at a lower position. The communication port 132 communicates the cooking cavity 111 and the ventilation surface 131. That is to say, after the oil stains and the like sucked into the protective cover 130 drip onto the inclined surface, they can flow along the inclined surface to the communication port 132 and be discharged outside the protective cover 130 through the communication port 132, further reducing the accumulation of oil stains in the protective cover 130, reducing the cleaning difficulty of the protective cover 130, and improving the cleaning effect of the protective cover 130.

[0097] It can be understood that the oil stains in the protective cover 130 are discharged into the cooking cavity 111 through the communication port 132. Compared with the accumulation of oil stains in the protective cover 130, the oil stains discharged into the cooking cavity 111 are convenient for the user to clean, improving the effect of the air fryer 100.

[0098] The communication port 132 is arranged close to the second end 134. That is to say, the communication port 132 is arranged at a relatively lower position, so that the oil stains flowing on the inclined surface can be discharged through the communication port 132, further reducing the accumulation of oil stains.

[0099] Moreover, since the communication port 132 communicates the cooking cavity 111 and the ventilation surface 131, the communication port 132 can promote the air flow while discharging the oil stains, improving the cooking effect.

[0100] Such as Figure 1 and Figure 3 As shown, in some embodiments, optionally, the communication port 132 is arranged at the second end 134.

[0101] In this embodiment, it is defined that the communication port 132 is arranged at the second end 134, that is, the communication port 132 is arranged at a lower position, which can further facilitate the oil stains flowing on the inclined surface to be quickly discharged through the communication port 132, reduce the accumulation of oil stains on the inner side of the protective cover 130, improve the cleaning effect of the air fryer 100, and improve the user experience.

[0102] Such as Figure 4 and Figure 5 As shown, in some embodiments, optionally, the air fryer 100 further includes an oil storage structure 160, and the oil storage structure 160 is arranged in the protective cover 130. The oil storage structure 160 can separate the ventilation surface 131 and the communication port 132.

[0103] In this embodiment, it is defined that the air fryer 100 further includes an oil storage structure 160. Specifically, the oil storage structure 160 is arranged on the protective cover 130. Specifically, the oil storage structure 160 is arranged on the ventilation surface 131, and the oil storage structure 160 can separate the ventilation surface 131 and the communication port 132. It can be understood that the oil storage structure 160 can collect oil stains. That is to say, the oil stains entering the protective cover 130 drip onto the ventilation surface 131 and flow to the oil storage structure 160 for collection on the inclined ventilation surface 131. When the protective cover 130 is removed, the oil stains collected in the oil storage structure 160 are cleaned intensively, which is beneficial to reducing the cleaning difficulty and improving the cleaning effect of the protective cover 130.

[0104] Moreover, since the oil storage structure 160 separates the ventilation surface 131 and the communication port 132, the oil stains on the ventilation surface 131 can be prevented from entering the cooking cavity 111 through the communication port 132 to contaminate the food materials. At this time, the communication port 132 is used for ventilation, which is beneficial to strengthening the air flow circulation in the cooking cavity 111 and thus improving the cooking effect.

[0105] As Figure 5 and Figure 6 shown, in some embodiments, optionally, the oil storage structure 160 is arranged around the communication port 132.

[0106] In this embodiment, it is defined that the oil storage structure 160 is arranged around the communication port 132, that is, the oil stains are collected on the periphery of the communication port 132, which is further convenient for cleaning the protective cover 130 and improves the cleaning effect.

[0107] In some embodiments, optionally, the ventilation surface 131 includes a first end 133 and a second end 134. The second end 134 is arranged closer to the central axis of the hot air component 120 than the first end 133.

[0108] In this embodiment, it is defined that the ventilation surface 131 includes a first end 133 and a second end 134. The second end 134 is arranged closer to the central axis of the hot air component 120 than the first end 133. That is to say, the second end 134 is close to the center position of the ventilation surface 131, and the first end 133 is close to the edge position of the ventilation surface 131. Along the height direction of the machine body 110, the first end 133 is higher than the second end 134. That is to say, the center position of the protective cover 130 is low and the edge position is high, so that the ventilation surface 131 is formed into an inclined surface.

[0109] The oil storage structure 160 is disposed on the ventilation surface 131 and is disposed near the second end 134. That is to say, the oil storage structure 160 is disposed at a lower position on the ventilation surface 131 to collect oil stains. When the protective cover 130 is removed, the oil stains collected in the oil storage structure 160 can be centrally cleaned, which is beneficial to reducing the cleaning difficulty and improving the cleaning effect of the protective cover 130.

[0110] As Figure 7 and Figure 8 shown, in some embodiments, optionally, the ventilation surface 131 includes a first end 133 and a second end 134. The second end 134 is disposed closer to the central axis of the hot air component 120 than the first end 133. Along the height direction of the machine body 110, the first end 133 is lower than the second end 134; the protective cover 130 is provided with a communication port 132, and the communication port 132 communicates the ventilation surface 131 and the cooking cavity 111, and the communication port 132 is disposed near the first end 133.

That is to say, the second end 134 is close to the central position of the ventilation surface 131, and the first end 133 is close to the edge position of the ventilation surface 131. Along the height direction of the machine body 110, the first end 133 is lower than the second end 134. That is to say, the central position of the protective cover 130 is high and the edge position is low, so that the ventilation surface 131 is formed as an inclined surface.

[0112] The protective cover 130 is further provided with a communication port 132, and the communication port 132 is disposed near the first end 133. That is to say, the communication port 132 is close to the edge of the ventilation surface 131 and is located at a low position. The communication port 132 communicates the cooking cavity 111 and the ventilation surface 131. That is to say, after the oil stains and the like sucked into the protective cover 130 drip on the inclined surface, they can flow along the inclined surface to the communication port 132 and be discharged out of the protective cover 130 through the communication port 132, further reducing the accumulation of oil stains in the protective cover 130, reducing the cleaning difficulty of the protective cover 130, and improving the cleaning effect of the protective cover 130.

[0113] It can be understood that the oil stains in the protective cover 130 are discharged into the cooking cavity 111 through the communication port 132. Compared with the accumulation of oil stains in the protective cover 130, the oil stains discharged into the cooking cavity 111 are convenient for the user to clean, and the cleaning effect of the air fryer 100 is improved.

[0114] In addition, since the communication port 132 is located at a lower position, it is convenient for the oil stains flowing on the inclined surface to be discharged through the communication port 132, further reducing the accumulation of oil stains. Moreover, since the communication port 132 connects the cooking cavity 111 and the ventilation surface 131, the communication port 132 can promote the flow of air while discharging the oil stains, improving the cooking effect.

[0115] In some embodiments, optionally, the ventilation surface 131 includes a first end 133 and a second end 134. The second end 134 is disposed closer to the central axis of the hot air component 120 than the first end 133.

The air fryer 100 further includes an oil storage structure 160, and the oil storage structure 160 is disposed on the ventilation surface 131 and is disposed close to the first end 133.

[0116] In this embodiment, it is defined that the ventilation surface 131 includes a first end 133 and a second end 134. The second end 134 is disposed closer to the central axis of the hot air component 120 than the first end 133. That is to say, the second end 134 is close to the center position of the ventilation surface 131, and the first end 133 is close to the edge position of the ventilation surface 131. Along the height direction of the body 110, the first end 133 is lower than the second end 134. That is to say, the center position of the protective cover 130 is high and the edge position is low, so that the ventilation surface 131 is formed as an inclined surface.

[0117] The oil storage structure 160 is disposed on the ventilation surface 131, and the oil storage structure 160 is disposed close to the first end 133. That is to say, the oil storage structure 160 is disposed at a lower position on the ventilation surface 131 to collect the oil stains. When the protective cover 130 is removed, the oil stains collected in the oil storage structure 160 are centrally cleaned, which is beneficial to reducing the cleaning difficulty and improving the cleaning effect of the protective cover 130.

[0119] In this embodiment, it is defined that the oil storage structure 160 includes an oil retaining rib 161. Specifically, the oil retaining rib 161 protrudes and extends on the ventilation surface 131. That is to say, the oil storage structure 160 is a rib protruding on the ventilation surface 131, so as to be able to collect the oil stains flowing on the ventilation surface 131. When the protective cover 130 is removed, it is convenient to clean the oil stains and improve the cleaning effect.

[0120] Moreover, when the protective cover 130 includes the communication port 132, since the oil baffle rib 161 separates the ventilation surface 131 and the communication port 132, it can also prevent the oil stain on the ventilation surface 131 from entering the cooking cavity 111 through the communication port 132 to contaminate the food materials. At this time, the communication port 132 is used for ventilation, which is beneficial to strengthening the air flow circulation in the cooking cavity 111, thereby improving the cooking effect.

[0121] Optionally, the oil baffle rib 161 is an annular rib, and the communication port 132 is arranged in the annular area surrounded by the annular rib, that is, the oil baffle rib 161 is arranged around the communication port 132.

When the protective cover 130 is removed, it is convenient to clean the oil stain, improving the cleaning effect.

[0124] Optionally, the oil sump 162 is an annular groove, and the communication port 132 is arranged in the annular area surrounded by the annular groove, that is, the oil sump 162 is located on the outer periphery of the communication port 132.

[0125] As Figure 1 、 Figure 2 and Figure 3 shown, in some embodiments, optionally, the protective cover 130 includes a first cover body 135. Along the height direction of the machine body 110, the first cover body 135 is opposite to the hot air assembly 120, and one side surface of the first cover body 135 facing the hot air assembly 120 includes a ventilation surface 131; wherein, the first cover body 135 is provided with a plurality of first ventilation openings 140, and along the height direction of the machine body 110, each first ventilation opening 140 penetrates through the first cover body 135.

[0126] In this embodiment, it is defined that the protective cover 130 includes a first cover body 135. Specifically, along the height direction of the machine body 110, the first cover body 135 is opposite to the hot air assembly 120, and one side surface of the first cover body 135 facing the hot air assembly 120 includes a ventilation surface 131. It can be understood that the communication port 132 is arranged on the first cover body 135.

[0127] A plurality of first ventilation openings 140 are provided on the first cover body 135. Specifically, along the height direction of the machine body 110, each first ventilation opening 140 penetrates through the first cover body 135. That is to say, each first ventilation opening 140 communicates the ventilation surface 131 and the cooking cavity 111, so that the air in the cooking cavity 111 can enter the protective cover 130 through the plurality of first ventilation openings 140. Under the action of the hot air assembly 120, the formed hot air flow flows out of the protective cover 130 to form a hot air circulation.

[0128] In addition, when the oil stains sucked into the protective cover 130 flow on the ventilation surface 131, they can also be discharged out of the protective cover 130 through the plurality of first ventilation openings 140, realizing the rapid discharge of oil stains, further reducing the accumulation of oil stains in the protective cover 130, facilitating the user to clean the discharged oil stains, and thus improving the cleaning effect of the air fryer 100.

[0129] Optionally, the plurality of first ventilation openings 140 are arranged around the outer periphery of the communication port 132, and the plurality of first ventilation openings 140 are arranged at intervals.

[0130] Such as Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, optionally, the protective cover 130 further includes a second cover body 136. One end of the second cover body 136 is connected to the machine body 110, and the other end of the second cover body 136 is connected to the first cover body 135.

[0133] A plurality of second ventilation openings 150 are provided on the second housing 136. Specifically, each second ventilation opening 150 communicates with the protection cavity 137 and the cooking cavity 111. It can be understood that the air in the cooking cavity 111 enters the protection cavity 137 through the plurality of first ventilation openings 140 on the bottom of the first housing 135 of the protective cover 130. Under the action of the hot air assembly 120, the formed hot air flows out through the plurality of second ventilation openings 150 into the cooking cavity 111, forming a hot air circulation to realize the heating and cooking of the food ingredients in the cooking cavity 111.

[0134] Optionally, the first housing 135 and the second housing 136 are of an integral structure. It can be understood that the integral structure has good mechanical properties, so the connection strength between the first housing 135 and the second housing 136 can be improved. In addition, the integral structure is also beneficial to the processing and production of the protective cover 130, reducing the manufacturing difficulty of the protective cover 130, and further reducing the production cost of the air fryer 100.

[0135] Such as Figure 2 As shown, in some embodiments, optionally, the protective cover 130 further includes a connecting portion 138. The connecting portion 138 is provided on the second housing 136 and is located outside the protection cavity 137. The second housing 136 is connected to the body 110 through the connecting portion 138.

[0136] In this embodiment, it is defined that the protective cover 130 further includes a connecting portion 138. Specifically, the connecting portion 138 is provided on the second housing 136. Specifically, the second housing 136 is connected to the body 110 through the connecting portion 138, so as to realize the fixed installation of the protective cover 130.

[0137] The connecting portion 138 is located outside the protection cavity 137, avoiding occupying the space inside the protection cavity 137 and avoiding the problem of interference between the connecting portion 138 and the blades 122 of the hot air assembly 120 inside the protection cavity 137.

[0138] Optionally, the connecting portion 138 and the second housing 136 are of an integral structure. Or the connecting portion 138, the second housing 136 and the first housing 135 are of an integral structure.

[0139] Such as Figure 2 As shown, in some embodiments, optionally, the connecting portion 138 includes a plurality of fixing ears 139. The plurality of fixing ears 139 are spaced apart, and each fixing ear 139 is connected to the body 110.

[0140] In this embodiment, it is defined that the connecting portion 138 includes a plurality of fixing ears 139. Specifically, the plurality of fixing ears 139 are spaced apart, and each fixing ear 139 is connected to the body 110, so as to improve the assembly stability between the protective cover 130 and the body 110.

[0141] Optionally, a part of the second cover 136 is bent away from the protection cavity 137 to form a plurality of fixing ears 139.

[0142] As Figure 1 shown, in some embodiments, optionally, the body 110 includes a pot body 112 and a reflector 113. Among them, the pot body 112 is provided with a cooking cavity 111, the hot air assembly 120 is arranged on the pot body 112, the reflector 113 is arranged in the cooking cavity 111 and is connected to the pot body 112; the protective cover 130 is connected to the pot body 112 or the reflector 113.

[0143] In this embodiment, it is defined that the body 110 includes a pot body 112 and a reflector 113. Specifically, the pot body 112 is provided with a cooking cavity 111, and the hot air assembly 120 is arranged on the pot body 112.

[0144] The reflector 113 is arranged in the cooking cavity 111, and the reflector 113 is connected to the pot body 112. It can be understood that by arranging the reflector 113 in the cooking cavity 111, the heat radiation in the cooking cavity 111 can be improved, thereby improving the heating efficiency of the air fryer 100.

[0145] The protective cover 130 is connected to the reflector 113 to realize the fixed installation of the protective cover 130. Alternatively, the protective cover 130 is connected to the pot body 112 to realize the fixed installation of the protective cover 130. Specifically, it can be set according to actual needs.

[0146] In some embodiments, optionally, the protective cover 130 and the reflector 113 are of an integral structure.

[0147] In this embodiment, it can be understood that the integral structure has good mechanical properties. Therefore, the connection strength between the protective cover 130 and the reflector 113 can be improved, and the assembly stability can be improved.

[0148] Moreover, the integral structure is also convenient for mass production, thereby reducing the manufacturing difficulty of the protective cover 130 and the reflector 113, improving the production efficiency, and being beneficial to reducing the production cost of the air fryer 100.

[0149] It can be understood that when the protective cover 130 and the reflector 113 are of an integral structure, the protective cover 130 can be fixedly installed by screwing the reflector 113 through and connecting it to the pot body 112.

[0150] As Figure 1As shown, in some embodiments, optionally, the hot air assembly 120 includes a motor 121, a blade 122, and an electromagnetic component 123. Among them, the motor 121 is disposed on the body 110, the blade 122 is disposed in the cooking cavity 111 and is connected to the motor 121. The protective cover 130 covers the side of the blade 122 facing the cooking cavity 111. The electromagnetic component 123 is disposed on the body 110 and is opposite to the blade 122. When the electromagnetic component 123 is powered on, at least a part of the blade 122 can generate heat.

[0151] In this embodiment, it is defined that the hot air assembly 120 includes a motor 121, a blade 122, and an electromagnetic component 123. Specifically, the motor 121 is disposed on the body 110, and the motor 121 is connected to the blade 122. That is to say, driven by the motor 121, the blade 122 rotates in the cooking cavity 111.

[0152] It can be understood that when the air fryer 100 stops or is powered off, due to inertia, the blade 122 will continue to rotate for a certain period of time, and there is a risk that the user may be injured by accidentally touching the rotating blade 122.

[0153] The protective cover 130 covers the side of the blade 122 facing the cooking cavity 111, thereby blocking the blade 122 and effectively avoiding the problem that the user may be injured by accidentally touching the blade 122 with a relatively high temperature or the rotating blade 122 during the operation of the air fryer 100, improving the safety of using the air fryer 100.

[0154] The electromagnetic component 123 is opposite to the blade 122, and when the electromagnetic component 123 is powered on, at least a part of the blade 122 can generate heat. That is to say, at least a part of the blade 122 has magnetic permeability. Specifically, when the electromagnetic component 123 is powered on, at least a part of the blade 122 with magnetic permeability can generate heat, thereby heating the surrounding air. At the same time, driven by the motor 121, the blade 122 rotates in the cooking cavity 111 and takes away the heat to form a hot air flow, dissipating the heat generated by the blade 122.

[0155] In detail, when the electromagnetic component 123 is powered on, it can generate an alternating magnetic field. Under the action of the alternating magnetic field, the blade 122 with magnetic permeability will generate heat. Through the interaction between the electromagnetic component 123 and the blade 122 with magnetic permeability, the temperature of the blade 122 can rise rapidly in a short time. At the same time, when the blade 122 rotates, a hot air flow is quickly generated in the cooking cavity 111.

[0156] Optionally, the body 110 is further provided with a heat dissipation cavity, an air inlet, and an air outlet. Among them, any one of the air inlet and the air outlet is communicated with the heat dissipation cavity, and the electromagnetic component 123 and the motor 121 are both located in the heat dissipation cavity.

[0157] It can be understood that during the operation of the air fryer 100, the electromagnetic component 123 and the motor 121 will generate heat. If heat dissipation is not carried out in a timely manner, it is easy to cause faults in the electromagnetic component 123 and the motor 121, reduce the service life of the electromagnetic component 123 and the motor 121, and increase the maintenance cost of the air fryer 100.

[0158] The electromagnetic component 123 and the motor 121 are located in the heat dissipation cavity. Air or air flow enters the heat dissipation cavity from the air inlet and can flow out through the air outlet. During this process, the heat on the surfaces of the electromagnetic component 123 and the motor 121 is carried away, thereby dissipating heat from the electromagnetic component 123 and the motor 121, reducing the probability of faults in the electromagnetic component 123 and the motor 121, extending the service life of the air fryer 100, and reducing the maintenance cost of the air fryer 100.

[0159] Optionally, the air fryer 100 further includes a power supply board, which is electrically connected to the electromagnetic component 123 and the motor 121. The power supply board is located in the heat dissipation cavity. That is to say, air or air flow enters the heat dissipation cavity from the air inlet and can flow out through the air outlet. During this process, in addition to carrying away the heat on the surfaces of the electromagnetic component 123 and the motor 121, it can also carry away the heat on the surface of the power supply board, thereby dissipating heat from the power supply board, reducing the probability of faults in the power supply board, ensuring the service life of the power supply board, and reducing the maintenance cost of the air fryer 100.

[0160] Optionally, the air fryer 100 further includes a cooling fan, which is arranged on the body 110 and is communicated with the air inlet.

[0161] Optionally, the heat dissipation cavity includes a first chamber and a second chamber. Specifically, the first chamber is communicated with the air inlet and the air outlet. The electromagnetic component 123 is located in the first chamber. That is to say, air or air flow enters and can flow out through the air outlet. During this process, the heat on the surface of the electromagnetic component 123 is carried away, thereby dissipating heat from the electromagnetic component 123 and reducing the probability of faults in the electromagnetic component 123.

[0162] The second chamber is communicated with the air inlet and the air outlet. The motor 121 and the power supply board are located in the second chamber. That is to say, air or air flow enters and can flow out through the air outlet. During this process, the heat on the surfaces of the motor 121 and the power supply board is carried away, thereby dissipating heat from the motor 121 and the power supply board and reducing the probability of faults in the motor 121 and the power supply board.

[0163] It can be understood that during the operation of the air fryer 100, the heat generated by the electromagnetic component 123 during operation is higher than the heat generated by other electronic control components (the motor 121 and the power supply board) during operation.

[0164] By placing the electromagnetic component 123 and other electronic control components (motor 121 and power board) in two different chambers for heat dissipation, it is possible to effectively avoid the problem of excessive temperature rise of other electronic control components (motor 121 and power board) caused by the high heat generated by the electromagnetic component 123 during operation, thereby affecting the heat dissipation of the motor 121 and the power board, thereby ensuring effective heat dissipation of the motor 121 and the power board, further reducing the probability of failure of the electronic control components, and thereby reducing the maintenance cost of the air fryer 100.

[0165] Optionally, the air fryer 100 also includes a heat insulation plate, which is arranged between the electromagnetic component 123 and the blades 122. That is to say, a high-temperature resistant heat insulation plate is arranged between the electromagnetic component 123 and the blades 122, which can effectively reduce the heat generated by the blades 122 from being transferred to the electromagnetic component 123, avoid the problem of excessive temperature rise of the electromagnetic component 123 due to the heat generated by the blades 122 being transferred to the electromagnetic component 123, extend the service life of the electromagnetic component 123, and ensure the stable operation of the air fryer 100.

[0166] Optionally, the heat insulation board includes a microcrystalline board or glass.
