[0041] The present utility model provides an air fryer 100.

[0042] Please refer to Figures 1 to 3 , in some embodiments of the present application, the air fryer 100 includes:

[0043] An appliance main body 10, in which a cooking space 111 is formed, and an air outlet passage 181 communicating with the cooking space 111 is provided;

[0044] A sealing member 30, which is disposed on the appliance main body 10 and closes the air outlet passage 181, and can change the size of the part of the air outlet passage 181 communicating with the outside. The surface of the sealing member 30 facing away from the air outlet passage 181 forms an attached wall surface 31; and

[0045] A first fan 50, which is disposed on the appliance main body 10 and is located outside the cooking space 111. The first fan 50 can guide the air flow to flow through the attached wall surface 31 and cause the sealing member 30 to flip away from the air outlet passage 181 to open the air outlet passage 181.

[0046] The air fryer 100 proposed in this application includes an appliance main body 10, a sealing member 30, and a first fan 50. A cooking space 111 is formed inside the appliance main body 10, and an air outlet passage 181 communicating with the cooking space 111 is provided on the appliance main body 10. The cooking space 111 can be used to place food materials. Under normal conditions, the air outlet passage 181 is closed or nearly closed by the sealing member 30. The sealing member 181 can be disposed in the air outlet passage 181, or can be disposed at the air outlet 1315 where the cooking space 111 communicates with the air outlet passage 181, or can also be disposed at the outlet end of the air outlet passage 181. When the air outlet passage 181 is opened, part of the gas in the cooking space 111 can be discharged outward. The first fan 50 is disposed outside the cooking space 111 and can drive the air flow to flow through the wall-attached surface 31 of the sealing member 30 facing away from the air outlet passage 181. When the air flow passes through the sealing member 30, due to the wall-attached effect, the air flow will flow close to the wall-attached surface 31 of the sealing member 30. During this process, it is equivalent to the sealing member 30 providing an adsorption force to the air flow, and the air flow will also exert a reaction force on the sealing member 30 to adsorb the sealing member 30, causing the sealing member 30 to flip away from the cooking space 111 and the side opposite to the air flow direction to open the air outlet passage 181. When the first fan 50 is closed or rotates at a low speed, the sealing member 30 is not affected by the adsorption force, so it can be reset under the action of gravity or other reset members can be provided to reset the sealing member 30 to close the air outlet passage 181. Among them, a diversion air duct 171 can be provided at the position where the sealing member 30 deflects, or the wall-attached surface 31 of the sealing member 30 can be set as a convex structure, so that the air flow can turn at the position of the sealing member 30 to increase the adsorption force on the sealing member 30.

[0047] In this way, when it is necessary to tenderly roast or flavor the food materials and adopt other cooking modes that do not require exhaust, the first fan 50 can be not turned on or the rotation speed of the first fan 50 can be reduced to make the sealing member 30 close the air outlet passage 181. When it is necessary to crisply roast the food materials or adopt other cooking modes that require exhaust, the first fan 50 can be turned on to make the sealing member 30 rotate to open the air outlet passage 181. And the rotation speed of the first fan 50 can also be controlled to control the air flow velocity and flow rate, and the rotation angle of the sealing member 30 can be controlled to adjust the opening size of the air outlet passage 181 to be applicable to a variety of different cooking modes.

[0048] In the embodiment of this application, both the first fan 50 and the sealing member 30 can be disposed outside the appliance main body 10; or a cooking space 111 and a diversion air duct 171 that are isolated from each other can be formed in the appliance main body 10, and the first fan 50 can be installed inside the appliance main body 10 to protect the first fan 50, the sealing member 30, etc.

[0049] Therefore, it can be understood that in the technical solution of the present utility model, an air outlet passage 181 communicating with the cooking space 111 is provided in the air fryer 100, and a movable sealing member 30 is provided to control the opening and closing state of the air outlet passage 181; the sealing member 30 is rotatably arranged, and a first fan 50 is provided. The first fan 50 can guide the air flow to blow through the wall-attached surface 31 of the sealing member 30 facing away from the cooking space 111. Due to the wall-attached effect, the air flow generates friction with the wall-attached surface 31 of the sealing member 30 and moves along the wall-attached surface 31. At this time, the sealing member 30 will apply a deflecting force to the air flow, and the air flow will also apply a reverse deflecting force to the sealing member 30, thereby driving the sealing member 30 to rotate away from the cooking space 111 to open the air outlet passage 181. With such a setting, when it is necessary to tenderly roast or flavor the food ingredients and adopt other cooking modes that do not require exhaust, the first fan 50 can be not turned on or the rotation speed of the first fan 50 can be reduced to make the sealing member 30 close the air outlet passage 181; when it is necessary to crispy roast the food ingredients or adopt other cooking modes that require exhaust, the first fan 50 can be turned on to make the sealing member 30 rotate to open the air outlet passage 181; and the air flow velocity and flow rate can also be controlled by controlling the rotation speed of the first fan 50, and the rotation angle of the sealing member 30 can be controlled to adjust the opening size of the air outlet passage 181 to be applicable to a variety of different cooking modes. That is to say, the technical solution of the present application can control the position of the sealing member 30 by controlling the start-stop state and rotation speed of the first fan 50, thereby adjusting the opening and closing state of the air outlet passage 181, so that the air fryer 100 can meet the usage requirements of a variety of cooking modes and enrich the functions of the air fryer 100.

[0050] Please refer to Figures 1 to 3 , in some embodiments of the present application, a diversion air duct 171 is formed in the appliance main body 10, and an air outlet 115 communicating with the diversion air duct 171 is provided. Part of the diversion air duct 171 is located on the side of the sealing member 30 facing away from the air outlet passage 181. The sealing member 30 is arranged between the diversion air duct 171 and the air outlet duct 181, the wall-attached surface 31 faces the diversion air duct 171, and the sealing member 30 can be turned over to the side of the diversion air duct 171;

[0051] The first fan 50 is arranged at the inlet end of the diversion air duct 171.

[0052] In this embodiment, a diversion air duct 171 is formed inside the appliance main body 10 and is located outside the cooking space 111. An air outlet 115 communicating with the external environment and the diversion air duct 171 is provided on the appliance main body 10. The diversion air duct 171 passes through the sealing member 30. With such a setting, since the sealing member 30 is located in the diversion air duct 171, the sealing member 30 can be flipped to one side of the diversion air duct 171 to open the air outlet passage 181. In some embodiments, the air outlet passage 181 can be communicated with the diversion air duct 171 when the sealing member 30 opens the air outlet passage 181, so that the gas discharged from the cooking space 111 can be discharged outwards along with the air flow in the diversion air duct 171 through the diversion air duct 171 and the air outlet 115.

[0053] Please refer to Figure 1 , in some embodiments of the present application, the appliance main body 10 includes a housing 11, an inner cover 13 and a heating module 15. The housing 11 is provided with an air outlet 115;

[0054] The inner cover 13 is disposed inside the housing 11. A receiving space 113 is formed above the inner cover 13, and a diversion structure 17 is provided. The diversion structure 17 and the inner cover 13 enclose a diversion air duct. The first fan 50 is disposed in the receiving space 113;

[0055] A cooking space 111 is formed below the inner cover 13. An air outlet passage 181 is formed between the inner cover 13 and the housing 11. The inner cover 13 is provided with an air outlet 1315 communicating the cooking space 111 and the air outlet passage 181. The heating module 15 is disposed in the cooking space 111 and is used to heat the cooking space 111.

[0056] In the embodiment of the present application, the orientation when the air fryer 100 is used and placed normally is described, and orientations such as above and below are defined accordingly. In this embodiment, the appliance main body 10 includes a housing 11 and an inner cover 13. An installation space is formed inside the housing 11, and the inner cover 13 is horizontally partitioned in the installation space, so that the installation space is divided into a placement space 113 above the inner cover 13 and a cooking space 111 below the inner cover 13. A flow guiding structure 17 is further provided in the placement space 113. The flow guiding structure 17 and at least part of the surface of the inner cover 13 facing away from the cooking space 111 enclose a flow guiding air duct 171. The flow guiding structure 17 can be a baffle, a cylinder or other structures. An air outlet 1315 communicating with the cooking space 111 is opened on the inner cover 13. An air outlet passage 181 located outside the cooking space 111 and communicating with the air outlet 1315 is formed between the inner cover 13 and the housing 11. The housing 11 is provided with an air outlet 115 communicating with the flow guiding air duct 171, and the first fan 50 is arranged in the placement space 113 to drive air flow into the flow guiding space. With such a setting, the structures such as the first fan 50, the sealing member 30 and the heating module 15 in the air fryer 100 are all accommodated in the housing 11 to protect each component, and the appearance of the air fryer 100 is kept tidy.

[0057] It should be noted that in this embodiment, the first fan 50 is arranged in the placement space 113 and needs to drive air flow into the flow guiding air duct 171. At this time, an air guiding port communicating with the placement space 113 can be opened on the housing 11, or the upper shell of the housing 11 can be a splicing structure formed by at least two components, and there is a non-sealed connection and an air inlet gap between the splicing positions of the two components, so that the external air flow can enter the placement space 113 under the drive of the first fan 50 and flow into the flow guiding air duct 171.

[0058] Among them, the appliance main body 10 may further include a storage basket 19 for placing food. An opening communicating with the cooking space 111 below the inner cover 13 is opened on the side wall of the housing 11, and the storage basket 19 is inserted into the opening; the appliance main body 10 can also be set as a flip structure, so that the housing 11 includes a pot body and a lid body. A cooking space 111 is formed in the pot body, the lid body covers the top opening of the pot body, and the inner cover 13 covers the surface of the lid body facing the pot body opening and encloses a placement cavity with the lid body.

[0059] In this embodiment, the heating module 15 is arranged in the cooking space 111, and can be set as a heating wire, electromagnetic heating, a hot air assembly, infrared heating, microwave heating or other heating structures, which is not limited herein.

[0060] In some embodiments, the first fan 51 has a horizontal velocity due to volute rectification, that is, a velocity towards the sealing member 30, while the second fan 53 performs an internal circulation within the cooking space 111. Due to the effect of the inner cover 13, the circulation flow path caused by the movement of the second fan 53 has a velocity parallel or nearly parallel to that at the position close to the sealing member 30. Therefore, it is more suitable for the first fan 51 to blow the sealing member 30 to move.

[0061] Please refer to Figure 2 and Figure 3 , in some embodiments of the present application, the diversion air duct 171 deflects at least at the position of the sealing member 30 and forms a first air duct 1711 and a second air duct 1713 that are connected. The first fan 50 is located at the inlet end of the first air duct 1711;

[0062] The second air duct 1713 passes through the sealing member 30, and the sealing member 30 can be flipped towards the first air duct 1711 side to connect the air outlet channel 181 with the second air duct 1713.

[0063] In this embodiment, the diversion air duct 171 is a zigzag flow path and deflects at least at the position of the sealing member 30. The first air duct 1711 and the second air duct 1713 of the diversion air duct 171 can be set as two connected straight air ducts, or the first air duct 1711 and the second air duct 1713 can be arc-shaped air ducts or other shapes; it can also be that the entire diversion air duct 171 is set as an arc-shaped air duct or set as a combination of multiple air ducts.

[0064] And making the diversion air duct 171 deflect at the position of the sealing member 30 means changing the flow direction of the air flow guided by the first fan 50 at the position of the sealing member 30. At this time, it is equivalent to the attachment wall surface 31 needing to exert a greater adsorption force on the air flow to change the air flow direction, that is, increasing the interaction force between the air flow and the sealing member 30, making it easier to open the sealing member 30, and there is no need to excessively increase the rotation speed of the first fan 50 in order to increase the air flow rate and velocity.

[0065] Please refer to Figures 1 to 3 , in some embodiments of the present application, the inner cover 13 includes a cover shell 131 and a flanging 133. The cover shell 131 protrudes towards the accommodation space 113 side and includes a top wall 1311 and a peripheral edge 1313 arranged around the top wall 1311. The flanging 133 extends from the lower edge of the peripheral edge 1313 towards the outside of the cover shell 131;

[0066] The diversion air duct 171 forms a first air duct 1711 above the top wall 1311 and a second air duct 1713 on the side of the peripheral edge 1313. The air outlet 1315 is opened on the peripheral edge. The sealing member 30 is arranged between the air outlet 1315 and the second air duct 1713, and the first fan 50 is arranged on the top wall 1311.

[0067] In this embodiment, the inner cover 13 is provided with a locally convex structure, including a housing 131 convex towards the accommodation space 113 and a flange 133 connected to the housing 131. The housing includes a top wall 1311 and a surrounding edge 1313 disposed around the top wall 1311. The flange 133 extends outward from the lower edge of the surrounding edge 1313 to the outside of the housing 131. The space formed inside the housing 131 can be used to install structures such as the heating module 15. Among them, the diversion air duct 171 includes a first air duct 1711 above the top wall 1311 and a second air duct 1713 on the side of the surrounding edge 1313. The first fan 50 is disposed on the top wall 1311 such that the air outlet of the first fan 50 faces the inlet end of the first air duct 1711. At the same time, the surrounding edge 1313 is provided with an air outlet 1315 communicating with the cooking space 111. At this time, the second air duct 1713 is located outside the air outlet 1315. The sealing member 30 can be directly shielded at the position of the air outlet 1315 and abutted against the surrounding edge 1313 to close the cooking space 111, or an air outlet channel 171 can be constructed by a wind guiding seat 17 outside the air outlet 1315 as in the following embodiment. A wind guiding seat 18 can be provided outside the air outlet 1315 as in the following embodiment. At this time, the sealing member 30 is used to close the opening of the air outlet channel 181 formed by enclosing the wind guiding seat 18 and the surrounding edge 1313 to prevent the cooking space 111 from exhausting air. One end of the sealing member 30 close to the first air duct 1711 is rotatably connected to the diversion structure 17 or the inner cover 13. Thus, when it is necessary to exhaust the cooking space 111, one end of the sealing member 30 away from the first air duct 1711 flips to the side of the first air duct 1711 to communicate the air outlet channel 181 with the second air duct 1713.

[0068] Please refer to Figure 2 and Figure 3 As shown in, in some embodiments of the present application, the appliance main body 10 further includes a wind guiding seat 18. The wind guiding seat 18 is disposed in the second air duct 1713 and surrounds the outside of the air outlet 1315 to enclose an air outlet channel 181 with the surrounding edge 133. The top of the air outlet channel 181 has an opening, and the sealing member 30 can abut against the wind guiding seat 18 to close the air outlet channel 181.

[0069] In this embodiment, the appliance main body 10 further includes a wind guiding base 18. The wind guiding base 18 surrounds the outside of a part of the perimeter 133 provided with the air outlet 1315, and forms an air outlet channel 181 with the perimeter 133. With such a setting, the air outlet channel 181 is communicated with the air outlet 1315, and the top of the air outlet channel 181 is open. At this time, the sealing member 30 can abut against the wind guiding base 18 to close the opening of the air outlet channel 181 formed by the wind guiding base 18 and the perimeter 133. And when in the closed state, the sealing member 30 is lifted by the wind guiding base 18, and the angle between the attached wall surface 31 and the first air duct 1711 can also be made less than 90°. This avoids the situation where there is only a small amount of air flow or no air flow passing through the sealing member 30 when the perimeter 133 is completely perpendicular to the first air duct 1711, ensuring that the sealing member 30 can be lifted under the attached wall action of the air flow so that the air outlet channel 181 is communicated with the diversion air duct 171, so that the gas in the cooking space 111 can be discharged outwards through the air outlet channel 181 and the diversion air duct 171.

[0070] In some embodiments of the present application, the air outlet 115 extends along the height direction of the air fryer 100. One end of the first air duct 1711 away from the first fan 50 extends to the side wall of the housing 11 and is communicated with the air outlet 115. One side of the second air duct 1713 facing away from the perimeter 1313 is communicated with the air outlet 115.

[0071] In the embodiment of the present application, taking the orientation when the air fryer 100 is in normal use as an example for description. Among them, the first air duct 1711 is located above the second air duct 1713 along the height direction of the air fryer 100. The air outlet 115 extends along the height direction of the air fryer 100 and is located at the height positions of the first air duct 1711 and the second air duct 1713. And one end of the first air duct 1711 away from the first fan 50 extends to the position of the air outlet 115 to be communicated with the blowing port, and one side of the second air duct 1713 facing away from the perimeter 1313 of the inner cover 13 is also communicated with the air outlet 115. With such a setting, the size of the air outlet 115 is increased and the air outlet efficiency is improved. In addition, when the sealing member 30 rotates towards the first air duct 1711 under the action of the air flow, the communication area between the first air duct 1711 and the second air duct 1713 will also decrease, and the first air duct 1711 is also communicated with the air outlet 115, so that part of the air flow can be directly discharged from the first air duct 1711 to the air outlet 115 under the guidance of the sealing member 30, avoiding the situation that the air flow above the sealing member 30 cannot be discharged in time, resulting in the sealing member 30 being pressed towards the second air duct 1713 side and affecting the opening area of the air outlet channel 181.

[0072] Please refer to Figure 1, in some embodiments of the present application, the heating module 15 includes a second fan 151 and a heating element 153. The second fan 151 can drive external air flow into the cooking space 111, and the heating element 153 can heat the air flow entering the cooking space 111.

[0073] In this embodiment, the heating module 15 in the cooking space 111 is a hot air assembly, including a second fan 151 and a heating element 153. At this time, a communication port can be opened on the lower side wall of the outer shell 11, or an air vent can be opened in the inner cover 13, so that the second fan 151 can drive external air flow into the cooking space 111. The heating element 153 can be a heating wire, a heating coil or other heating structures. The heating element 153 can be arranged on the blades of the second fan 151, or at the air inlet or the air outlet of the second fan 151 to heat the air flow driven by the second fan 151 to form hot air. The hot air flowing in the cooking space 111 can transfer heat to the food ingredients to cook the food ingredients, and the circulating flow of the hot air makes the food ingredients evenly heated everywhere. In addition, during the cooking process, the hot air can also provide a certain thrust to the sealing member 30. It should be noted that when it is not necessary to open the air outlet channel 181, the rotation speed of the second fan 151 can be adjusted to be small to prevent the air flow driven by the second fan 151 from blowing open the sealing member 30. When it is necessary to open the air outlet channel 181, increase the rotation speed of the second fan 151 to assist in opening the sealing member 30. Or, the rotation speed of the second fan 151 can always be relatively small. At this time, the thrust provided by the hot air is weak and can only assist in opening the air outlet channel 181 when it is needed. When it is not necessary to open the air outlet channel 181, the thrust of the hot air on the sealing member 30 will not cause the sealing member 30 to open or only open a certain gap.

[0074] It should be noted that in this embodiment, two sets of driving members can be respectively provided to drive the first fan 50 and the second fan 151, or as in the following embodiment, a driving device can be provided to drive the first fan 50 and the second fan 151 at the same time, which is not limited herein.

[0075] Please refer to Figure 1 , in some embodiments of the present application, the inner cover 13 is provided with an air vent. The second fan 151 is arranged below the inner cover 13, and the air inlet of the second fan 151 is arranged facing the air vent. The heating element 153 is arranged below the inner cover 13.

[0076] In this embodiment, an air vent communicating the accommodation space 113 and the cooking space 111 is formed in the inner cover 13, and the second fan 151 is arranged below the inner cover 13 with the air inlet of the second fan 151 facing the air vent. At this time, an air guide port communicating the accommodation space 113 can be formed in the upper part of the outer shell 11, or the upper shell of the outer shell 11 can be a splicing structure formed by at least two components, and there is an air inlet gap at the non-sealed connection between the splicing positions of the two components, so that the external air flow can enter the cooking space 111 through the accommodation space 113 and the air vent under the drive of the second fan 151, and be heated by the heating element 153 and flow in the cooking space 111 to heat the food ingredients. The second fan 151 can be an axial flow fan and blow downward, and the air outlet channel 181 and the sealing member 30 are generally arranged at the top position of the cooking space 111, which can reduce the air flow driven by the second fan 151 flowing into the cooking space 111 from blowing towards the sealing member 30, and prevent the sealing member 30 from being blown open by the air flow in the cooking space 111 when the air outlet channel 181 does not need to be opened, so as to avoid being unable to select the cooking mode.

[0077] Please refer to Figure 1 , in some embodiments of the present application, the appliance main body 10 further includes a drive module 70. The drive module 70 is arranged in the accommodation space 113, and the output shaft of the drive module 70 penetrates through the air vent. Both the first fan 50 and the second fan 151 are sleeved on the drive shaft 71 of the drive module 70.

[0078] In this embodiment, the appliance body 10 further includes a driving module 70. The driving module 70 is disposed in the accommodating space 113. The driving module 70 can be a driving motor, and the output shaft of the driving motor is used as the driving shaft 71. The driving module 70 can also be a combination of a driving motor and a transmission mechanism. The transmission mechanism can be a worm and gear transmission mechanism, a rack and pinion transmission mechanism, a gear transmission mechanism, a belt transmission mechanism, or a combination of at least two transmission mechanisms. The output end of the transmission structure is set as the output shaft. The output shaft of the driving module 70 is passed through the ventilation port of the inner cover 13, and the first fan 50 located above the inner cover 13 and the second fan 151 located below the inner cover 13 are both sleeved on the output shaft. The output shaft can be driven by the driving device to rotate, so as to drive the first fan 50 and the second fan 151 to rotate. With such a setting, when the air outlet channel 181 does not need to be opened, both the first fan 50 and the second fan 151 operate at a relatively low speed, and there is not enough air flow passing through the sealing member 30 to cause the sealing member 30 to rotate and open under the wall attachment effect, nor will there be too much hot air blowing open the sealing member 30. When the air outlet channel 181 needs to be opened, the rotation speeds of the first fan 50 and the second fan 151 can be increased, so that the sealing member 30 is opened under the action of the external air flow attraction and the internal hot air thrust. In addition, with this setting structure, the air flow driven by the first fan 50 can also dissipate heat from the driving module 70, so as to take away the heat generated by continuously turning on the driving module 70 during the operation of the air fryer 100 and dissipate it outward through the diversion air duct 171.

[0079] Both the first fan 50 and the second fan 151 are sleeved on the driving shaft 71 of the driving module 70, so that the first fan 50 and the second fan 151 can start and stop synchronously, enabling the cooking module to dissipate heat in a timely manner; and the number of driving modules 70 provided in the air fryer 100 is reduced, simplifying the internal structure of the air fryer 100.

[0080] In this embodiment, the first fan 50 can be set as a vortex blower, the second fan 151 can be set as an axial flow fan, and the fan blades of the first fan 50 and the second fan 151 are arranged back to back.

[0081] In an embodiment of the present application, the included angle α between the extending direction of a part of the diversion air duct 171 located at the wall attachment surface 31 and the normal line of the wall attachment surface 31 satisfies 60° ≤ α ≤ 120°.

[0082] In the embodiments of the present application, the diversion air duct 171 is provided to guide the flow of the air current driven by the first fan 50; that is, the extension direction of the diversion air duct 171 is the flow direction of the air current, and the included angle α between the extension direction of the diversion air duct 171 at the position of the wall-attached surface 31 and the normal direction of the wall-attached surface 31 satisfies 60° ≤ α ≤ 120°, where α can take values of 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120° or any value between 60° and 120°; with such a setting, a relatively obvious wall-attached phenomenon occurs when the air current flows through the sealing member 30, and the suction force exerted by the air current on the sealing member 30 is relatively large, which is convenient for rotating the sealing member 30 to open the air outlet channel 181.

[0083] In some embodiments of the present application, the wall-attached surface 31 protrudes in a direction away from the air outlet channel 181.

[0084] In this embodiment, the wall-attached surface 31 protrudes in a direction away from the air outlet channel 181. With such a setting, when the air current flows towards the sealing member 30, it will flow along the protruding wall-attached surface 31 under the action of wall attachment, which can be regarded as the wall-attached surface 31 needs to exert a greater attractive force on the air current to change the flow direction of the air current; at this time, the reaction force exerted by the air current on the sealing member 30 is also greater, which is more conducive to driving the sealing member 30 to rotate to open the air outlet channel 181. In this embodiment, the wall-attached surface 31 can be a protruding folded surface, or a cylindrical surface, a spherical surface, and other regular or irregular protruding surfaces.

[0085] In some embodiments of the present application, the wall-attached surface 31 is an arc surface.

[0086] In this embodiment, the wall-attached surface 31 is a protruding arc surface. With such a setting, the resistance suffered by the air current during the process of flowing through the wall-attached surface 31 can be reduced, so that the air current flows more smoothly along the wall-attached surface 31, and the air current is prevented from exerting a force on the sealing member 30 towards the side of the air outlet channel 181.

[0087] Please refer to Figures 1 to 3 , in some embodiments of the present application, the wall-attached surface 31 is a plane.

[0088] In this embodiment, the wall-attached surface 31 is a plane. With such a setting, when the air current flows through the wall-attached surface 31, the directions of the forces exerted on the sealing member 30 at different positions of the wall-attached surface 31 are substantially the same, that is, the forces on each part of the sealing member 30 are substantially consistent, which is conducive to driving the sealing member 30 to rotate.

[0089] In an embodiment of the present application, there is a leakage gap between the sealing member 30 and the opening edge of the air outlet channel 181;

[0090] and / or, the sealing member 30 is provided with leakage holes.

[0091] In this embodiment, an air leakage gap communicating with the air outlet passage 181 may be provided between the sealing member 30 and the opening edge of the air outlet passage 181, or air leakage holes communicating with the air outlet passage 181 may be formed in the sealing member 30. With such arrangements, it can be avoided that the cooking space 111 is completely sealed when the sealing member 30 covers the air outlet passage 181, so that the sealing member 30 is difficult to be driven to open by the first fan 50 due to the negative pressure inside the cooking space 111.

[0092] Among them, the method of providing an air leakage gap between the sealing member 30 and the opening edge of the air outlet passage 181 can be as follows. When the sealing member 30 is located outside the cooking space 111 and covers the air outlet passage 181 by being placed on the outer wall of the cooking space 111, convex ribs, convex blocks or other convex structures may be protruded on a partial area of the surface of the sealing member 30 facing the air outlet passage 181, so that the convex structures abut against the outer wall of the cooking space 111; or convex structures may be protruded on the outer wall of the cooking space 111 to abut against the sealing member 30. In both cases, an air leakage gap can be formed between the opening edge of the air outlet passage 181 and the sealing member 30 when the sealing member 30 covers the air outlet passage 181. When the sealing member 30 is located in the air outlet passage 181 when covering the air outlet passage 181, the size of the sealing member 30 may be slightly smaller than that of the air outlet passage 181, or an air leakage gap may be formed between the edge of the air outlet passage 181 and the sealing member 30 when the sealing member 30 covers the air outlet passage 181.

[0093] In an embodiment of the present application, the air fryer 100 further includes a flavoring module, which is communicated with the cooking space 111 to supply flavor gas to the cooking space 111.

[0094] In this embodiment, a flavoring module is provided in the air fryer 100. The flavoring module may be a containing structure such as a smoking material box, which can be used to place smoking materials. The smoking material box is communicated with the cooking space 111 to supply flavor gas to the cooking space 111. Among them, the smoking material box can be directly placed in the cooking space 111, or a conduction structure such as an air duct may be provided between the smoking material box and the cooking space 111 to communicate the smoking material box and the cooking space 111. In addition, the smoking material can be directly lit and placed in the smoking material box, or a heating structure may be provided in the flavoring module to heat the smoking material in the smoking material box. In both cases, the flavor gas generated by the combustion of the smoking material can be discharged into the cooking space 111. The flavoring module may also be only a diversion structure, which is provided on the appliance main body 10 and communicated with the cooking space 111, so that the flavoring module can be communicated with an external flavor gas generation module to introduce the externally generated flavor gas into the cooking space 111.

[0095] The setting of the flavoring module can impart the required flavor substances to the ingredients during the cooking process, enabling the ingredients to emit the required flavors, such as smoky flavors, fruity flavors, or other flavors. When the flavoring module is enabled for flavoring, the first fan 50 stops moving, causing the sealing member 30 to block the air outlet passage 181 as much as possible, so that the cross-section of the air outlet passage 181 communicating with the outside is minimized, thereby slowing down the emission of the flavor gas from the cooking space 111, increasing the contact time between the flavor substances and the ingredients, and enabling more flavor substances to penetrate into the ingredients, so that users can have a better flavor experience when enjoying the ingredients.

[0096] In some embodiments, the first fan 50 can drive the air flow blocking member 30 to drive the blocking member 30 to rotate and change the cross-sectional area of the air outlet passage 181 communicating with the outside as the cooking process changes.

[0097] In some embodiments, the change in the cooking process includes the adaptive change in the rotational speed of the first fan 50 as the state of the food changes during cooking.

[0098] In some embodiments, the change in rotational speed includes; transitioning from a high wind speed at the start of cooking to quickly cook the food to a low wind speed for coloring near the end of cooking. For example, when adjusting crispy roasting / tender roasting, at the beginning of cooking, the food releases a large amount of water vapor, which is just discharged through the large-area conduction of the air outlet passage 181 to leave an appropriate amount of water vapor to adjust the degree of crispy roasting / tender roasting. Near the end of cooking, the conduction area of the air outlet passage 181 is just closed or reduced to leave an appropriate amount of water vapor to adjust the degree of crispy roasting / tender roasting. Another example, during flavoring, at the beginning of cooking, mainly cooking the food and preheating the flavoring materials, a high wind speed and a large-area conduction of the air outlet passage 181 are required. Near the end of cooking, the flavor substances are just allowed to settle on the food through a low wind speed or zero wind speed, and the conduction area of the air outlet passage 181 is closed or reduced to reduce the leakage of flavor substances, improving the flavoring effect.

[0099] In some embodiments, the change in rotational speed includes; transitioning from a high wind speed at the start of cooking to dehumidify (such as frozen products) to a medium wind speed during cooking to cook the food.

[0100] Of course, any adaptive change in the rotational speed of the first fan 50 as the state of the food changes during cooking (including remaining constant) is within the scope of protection of this application, and will not be listed one by one here.

[0101] In some embodiments, the change in the cooking process includes the change in the temperature in the cooking space 111.

[0102] With such a setting, the rate of connection between the cooking process and the gas in the cooking space 111 and the outside can be linked to provide a better cooking environment for the food.

[0103] The above are only the preferred embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
