Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] The utility model provides an air fryer 100.

[0043] Combined with reference Figures 1 to 5 In some embodiments of the present application, the air fryer 100 includes:

[0044] A device body 10, wherein the device body 10 is formed with a cooking space 113 and an air outlet passage 117, wherein the cooking space has an air outlet 135 for communicating with the air outlet passage 117; and

[0045] The sealing structure 30 , at least a portion of the sealing structure 30 shields the air outlet 135 or is separated in the air outlet channel 117 , and at least a portion of the sealing structure 30 can be deformed by heat to open the air outlet 135 or make the air outlet channel 117 conductive.

[0046] The air fryer 100 proposed in the present application can be an air fryer, an oven or a steam oven, etc. The air fryer 100 includes a device body 10 and a sealing structure. A cooking space 113 and an air outlet channel 117 for connecting the cooking space 113 with the external environment are formed in the device body 10. The cooking space 113 has an air outlet for connecting with the air outlet channel 117. The air outlet 135 can be square, circular, elliptical, polygonal or other regular or irregular shapes; the cooking space 113 can be used to place food, and the sealing structure 30 can be shielded at the position of the air outlet 135 to separate the cooking space 113 from the air outlet channel 117. The sealing structure can also be separated in the air outlet channel 117 to make the air outlet channel 117 non-conductive. When the air outlet 135 is blocked by the sealing structure or the air outlet channel 117 is blocked, the gas in the cooking space 113 cannot be quickly discharged from the air outlet channel 117135. In this way, for cooking modes that require tender roasting or smoking or other cooking modes that require keeping the cooking space closed, the discharge of water vapor and aromatic substances in the cooking space 113 can be slowed down or avoided, so that the food is in a cooking environment with relatively high humidity or aroma concentration; the moisture of the food can be maintained or the food can better absorb aromatic substances, thereby improving the smoking effect.

[0047] In addition, in the embodiment of the present application, at least a portion of the sealing structure 30 is set as a thermosensitive deformation structure. At this time, the portion of the thermosensitive deformation structure will be deformed when the thermosensitive temperature is reached, and the air outlet 135 will be opened or the air outlet channel 117 will be connected. At this time, the gas in the cooking space 113 can be discharged outward through the air outlet 135 and the air outlet channel 117; for example, in a cooking mode that requires crispy baking of ingredients, the air outlet 135 and the air outlet channel 117 can be kept open, so that the water vapor discharged and vaporized during the cooking process of the ingredients can be continuously discharged from the cooking space 113, thereby reducing the moisture of the ingredients, thereby achieving a crispy baking cooking effect.

[0048] In this way, when it is necessary to tender-roast or smoke the food or to adopt other cooking modes that do not require exhaust or only require a small amount of exhaust, the heating temperature in the cooking space 113 can be set below the thermistor temperature of the sealing structure 30 or the heating element for controlling the sealing structure 30 is not turned on, so that the sealing structure 30 shields the air outlet 135 or blocks the air outlet channel 117; when it is necessary to crisp the food or to adopt other cooking modes that require exhaust, the heating temperature in the cooking space 113 is set above the thermistor temperature of the sealing structure 30 or the heating element for controlling the sealing structure 30 is turned on to increase the temperature around the sealing structure 30, so that the sealing structure 30 is movable to open the air outlet 135 or connect the air outlet channel 117; and the degree of activity of the sealing structure 30 can also be controlled by the heating temperature in the cooking space 113 or the heating element to adjust the opening size of the air outlet 135 or the degree of conduction of the air outlet channel 117, so as to be suitable for a variety of different cooking modes.

[0049] The sealing structure 30 may be moved in a manner that the volume of the sealing structure 30 is shrunk, or the sealing structure 30 is moved, which is not limited here.

[0050] Therefore, it can be understood that the technical solution of the present application is to set an air outlet channel 117 connected to the cooking space 113 in the air fryer 100, and set a sealing structure 30 for shielding the air outlet 135 between the cooking space 113 and the air outlet channel 117 or to be separated in the air outlet channel 117. At least part of the sealing structure 30 can be activated to control the opening and closing state of the air outlet 135 of the cooking space 113 or the conduction state of the air outlet channel 117 when the thermosensitive temperature is reached. A heating element can also be separately provided to control the shape of the sealing structure 30. When it is necessary to tender-roast or smoke the food or adopt other cooking modes that do not require exhaust, the temperature around the sealing structure 30 can be controlled to be below the thermosensitive temperature, and the sealing structure 30 will not move, so that the sealing structure 30 is in a state of shielding the air outlet 135 or blocking the air outlet channel 117. At this time, the water vapor, aroma gas or other gas in the cooking space 113 cannot be discharged through the air outlet 135 and the air outlet channel 117, and can be retained in the cooking space 113 for a long time, so that the moisture of the food is not easy to lose in an environment with high humidity or high concentration of aroma gas, or the food is in an environment of aroma gas for a long time to absorb aroma substances. When it is necessary to crisp roast the food or adopt other cooking modes that require exhaust, the temperature around the sealing structure 30 can be raised to the thermosensitive temperature of the sealing structure 30, and the sealing structure 30 can be moved to open the air outlet 135 or conduct the air outlet channel 117135, and the water vapor or other gas in the cooking space 113 can be discharged outward through the air outlet 135 and the air outlet channel 117. In addition, the temperature around the sealing structure 30 can be controlled to control the activity of the sealing structure 30, so that the opening size of the air outlet 135 or the degree of conduction of the air outlet channel 117 can be adjusted to be suitable for a variety of different cooking modes. That is, the technical solution of the present application uses a deformable sealing structure 30 to adjust the conduction state between the cooking space 113 and the outside world, so that the air fryer 100 can meet the use requirements of a variety of cooking modes, enriching the functions of the air fryer 100.

[0051] Please refer to Figures 2 to 5 , the sealing structure 30 comprises:

[0052] A sealing member 31, wherein the sealing member 31 is movably disposed on the device body 10, and at least a portion of the sealing member 31 covers the air outlet 135 or is separated in the air outlet channel 117; and

[0053] The thermal deformation element 33 is disposed on the device body 10 and can be deformed by heat to drive the sealing member 31 to move to open the air outlet 135 or make the air outlet channel 117 conductive.

[0054] In this embodiment, the sealing structure 30 is composed of a sealing member 31 and a thermo-sensitive deformable element 33. The sealing member 31 is used to shield the air outlet 135 or block the air outlet channel 117, and the sealing member 31 is movable and can be driven and controlled by the thermo-sensitive deformable element 33. At least part of the structure of the thermo-sensitive deformable element 33 can be made of a shape memory alloy, such as a nickel-titanium-based shape memory alloy, a copper-based shape memory alloy, or an iron-based shape memory alloy; so that the thermo-sensitive deformable element 33 has the ability to deform under heat; the thermo-sensitive deformable material has a deformation temperature under heat, and only when the temperature around the thermo-sensitive deformable element 33 reaches the deformation temperature of the thermo-sensitive deformable element 33, the thermo-sensitive deformable element 33 will deform and drive the sealing member 31 to move; when the deformation temperature is not reached, the thermo-sensitive deformable element 33 maintains a normal shape and will not drive the sealing member 31 to move. The thermo-sensitive deformation element 33 may sense the temperature in the cooking space 113, for example, the thermo-sensitive deformation element 33 may be arranged in the air outlet channel 117135 or the cooking space 113; or a heating element may be arranged in the air fryer 100 to control the deformation state of the thermo-sensitive deformation element 33. In the embodiment of the present application, the movable distance of the sealing member 31 may be controlled by adjusting the temperature around the thermo-sensitive deformation element 33, thereby controlling the opening degree of the air outlet 135 or the conduction degree of the air outlet channel 117. The deformation mode of the thermo-sensitive deformation element 33 may be volume expansion or contraction, length extension or shortening, or folding or stretching of the shape in the following embodiments, etc., which is not limited here. The sealing member 31 may be rotatable so that the sealing member 31 moves away from the air outlet 135 or is misaligned with the air outlet 135 when rotating, thereby opening the air outlet 135; or the sealing member 31 may be rotated and tilted relative to the cross-section of the air outlet channel 117 to make the air outlet channel 117 conductive; the sealing member 31 may also be translatably arranged, by which the sealing member 31 is moved away from the air outlet 135 or is misaligned with the air outlet 135, thereby opening the air outlet 135.

[0055] Please refer to Figure 6 and Figure 7 In some embodiments of the present application, the sealing member 31 is rotatably disposed on the device body 10 .

[0056] In this embodiment, the sealing member 31 is rotatably disposed on the appliance body 10; wherein, when the sealing member 31 is used to cover the air outlet 135, the sealing member 31 can be rotated toward the inside of the cooking space 113, or can be rotated toward the outside of the cooking space 113 to open the air outlet 135; when the sealing member 31 is separated from the air outlet channel 117, the sealing member can be rotated along the air flow direction in the air outlet channel 117 to make the air outlet channel 117 conductive. When the thermo-sensitive deformable element 33 is deformed by heat, it drives the sealing member 31 to rotate; taking the thermo-sensitive deformable element 33 driving the sealing member 31 to rotate toward the outside of the cooking space 113 as an example, the thermo-sensitive deformable element 33 may be arranged inside the cooking space 113, and push the sealing member 31 toward the outside of the air outlet 135 by stretching, stretching or expanding, thereby opening the air outlet 135; or the thermo-sensitive deformable element 33 may be arranged outside the cooking space 113, and pull the sealing member 31 toward the outside of the air outlet 135 by retraction or other deformation, thereby opening the air outlet 135. It is understandable that if the sealing member 31 opens the air outlet 135 by rotating toward the inside of the cooking space 113, it may also be that the thermo-sensitive deformable element 33 pushes or pulls the sealing member 31 to rotate, which is not described in detail here.

[0057] Please refer to Figure 6 and Figure 7 In some embodiments of the present application, the sealing member 31 covers the air outlet 135, and the thermal deformation element 33 is disposed in the air outlet 135. When the thermal deformation element 33 is deformed by heat, it pushes the sealing member 31 to rotate toward the outside of the air outlet 135.

[0058] In this embodiment, the thermo-sensitive deformation element 33 is arranged inside the air outlet 135, so that when the air outlet 135 is deformed by heat, the sealing member 31 can be pushed to the outside of the air outlet 135 to open the air outlet 135. In this way, the deformation state of the thermo-sensitive deformation element 33 can be controlled by the temperature in the cooking space 113. By making the heating temperature in the cooking space 113 different in different cooking modes, whether the thermo-sensitive deformation element 33 is deformed and the degree of deformation can be directly controlled according to different cooking modes; it is possible to deform the thermo-sensitive deformation element 33 without additionally setting a heating element. Among them, the thermo-sensitive deformation element 33 can be arranged at any position of the edge of the air outlet 135, or the thermo-sensitive deformation element 33 can be arranged at at least two positions of the edge of the air outlet 135; for example, taking the air outlet 135 as a square, the thermo-sensitive deformation element 33 can be arranged at any side of the air outlet 135, or the thermo-sensitive deformation element 33 can be arranged at at least two sides, or at least two thermo-sensitive deformation elements 33 can be arranged at any side, which is not limited here.

[0059] Combined with reference Figures 2 to 5 In some embodiments of the present application, the thermal deformation element 33 includes:

[0060] A connecting portion 331 having a first end and a second end spaced apart from each other, wherein the first end is connected to the device body 10; and

[0061] The pushing portion 333 is connected to the second end and folded at the connecting portion 331 . The pushing portion 333 can extend outward from the air outlet 135 under heating conditions to push the sealing member 31 .

[0062] In this embodiment, the thermo-sensitive deformation element 33 includes a connecting portion 331 and a pushing portion 333, wherein the connecting portion 331 has a first end and a second end spaced apart along its length direction, the first end of the connecting portion 331 is connected to the appliance body 10, and the second end of the connecting portion 331 is extended to the air outlet 135, the pushing portion 333 is connected to the second end of the connecting portion 331, and can be folded on the connecting portion 331, when the deformation temperature is reached, the pushing portion 333 can be unfolded from the connecting portion 331 to the outside of the air outlet 135 and extend out of the air outlet 135, thereby pushing the sealing member 31 outward to open the air outlet 135. When cooking is completed or the temperature in the cooking space 113 drops below the deformation temperature, the pushing portion 333 retracts to the inside of the air outlet 135 and folds to the connecting portion 331, and the sealing member 31 is not affected by the outward thrust of the pushing portion 333, so that the sealing member 31 can be reset to a position shielding the air outlet 135. Among them, the resetting of the sealing member 31 can be achieved by setting a spring or other resetting structure; or the sealing member 31 can be connected to the pushing portion 333 so that it can be reset following the pushing portion 333 when the pushing portion 333 retracts; or the sealing member 31 can be made to fall back under the action of gravity to cover the air outlet 135.

[0063] Combined with reference Figures 8 to 10 In some embodiments of the present application, the thermal deformation element 33 further includes a connecting rod 335 , both ends of which are respectively connected to the edges of the air outlet 135 , and the first end is connected to the connecting rod 335 .

[0064] It can be understood that the thermo-sensitive deformation element 33 is made of a thermo-sensitive deformation material such as a memory alloy, and needs to be installed and fixed on the appliance body 10. In this embodiment, the thermo-sensitive deformation element 33 includes a connecting rod 335, a connecting portion 331, and a pushing portion 333. The connecting rod 335 is fixed in the air outlet 135, and the two ends of the connecting rod 335 are respectively connected to the edges of the air outlet 135. For example, in the above embodiment, the air outlet 135 includes an air outlet body 1351 and an avoidance gap 1353. The connecting rod 335 can be set in the avoidance gap 1353 of the air outlet 135, and the two ends of the connecting rod 335 are respectively connected to the two side edges of the avoidance gap 1353. The first end of the connecting portion 331 is fixedly connected to the connecting rod 335, and the second end of the connecting portion 331 is connected to the pushing portion 333. The connecting portion 331 may be connected to the middle of the connecting rod 335 or to any position between the two ends of the connecting rod 335. In addition, the connecting rod 335 and the connecting portion 331 may be integrally formed and made of a thermosensitive deformable material, or the connecting rod 335 may be made of other materials and then fixedly connected or detachably connected to the connecting portion 331. The thermosensitive deformable element 33 is connected to the device body 10 through the connecting rod 335. Compared with only connecting the first end of the connecting portion 331 to the device body 10, the number of connection positions between the thermosensitive deformable element 33 and the device body 10 is increased, and the connection strength can be improved.

[0065] Please refer to Figure 3 In some embodiments of the present application, the air outlet 135 has two side edges spaced apart along the central axis direction thereof, and the connecting portion 331 is spaced apart from the outer side edge of the air outlet 135 ; when the pushing portion 333 is folded relative to the connecting portion 331 , the pushing portion 333 is located on the inner side of the air outlet 135 .

[0066] In this embodiment, the surrounding wall that encloses the cooking space 113 has a certain wall thickness, so that the air outlet 135 opened on the surrounding wall of the cooking space 113 has a certain depth in the direction of the central axis of the air outlet 135. At this time, the air outlet 135 has an inner side edge close to the inner side of the cooking space 113 and an outer side edge located on the outer wall of the cooking space 113. The thermosensitive deformation element 33 is arranged on the inner side of the air outlet 135, so that the connecting portion 331 of the thermosensitive deformation element 33 is spaced apart from the outer side of the air outlet 135. At this time, the area between the connecting portion 331 and the outer wall surface of the cooking space 113 forms a folding area. When there is no need to open the air outlet 135 to make the pushing portion 333 folded on the connecting portion 331, the pushing portion 333 is located in the folding area, so that the pushing portion 333 does not exceed the outer wall surface of the cooking space 113 in the folded state, ensuring that the sealing member 31 can be close to the outer wall surface of the cooking space 113, thereby better shielding the air outlet 135, avoiding air leakage problems, and improving the sealing performance of the sealing member 31 in shielding the air outlet 135.

[0067] Please refer to Figure 4 In some embodiments of the present application, the thermal deformation element 33 is arranged on a side of the air outlet 135 away from the rotation axis of the sealing member 31 .

[0068] In this embodiment, the thermosensitive deformation element 33 is arranged on a side away from the rotation axis of the sealing member 31, which means that the distance between the force-bearing position of the sealing member 31 and the rotation axis of the sealing member 31 is extended as much as possible, that is, the lever arm is extended. When the lever arm is longer, the force required to push the sealing member 31 to rotate is smaller, so that the thermosensitive deformation element 33 can more easily push the sealing member 31 open to open the air outlet 135.

[0069] Please refer to Figure 8 In some embodiments of the present application, the air outlet 135 includes an air outlet body 1351 and an avoidance gap 1353 arranged at the edge of the air outlet body 1351 , and the thermal deformation element 33 is arranged in the avoidance gap 1353 .

[0070] In the embodiment of the present application, the purpose of setting the air outlet 135 connected to the cooking space 113 is to discharge the water vapor or other gases in the cooking space 113, so as to achieve cooking modes such as crispy baking. In this embodiment, the air outlet 135 includes an air outlet body 1351 and an avoidance gap 1353 opened at the edge of the air outlet body 1351, and the thermal deformation element 33 is located in the avoidance gap 1353; such a setting can not only increase the air outlet area of ​​the cooking space 113 through the avoidance gap 1353, but also avoid the setting of the thermal deformation element 33 to block the air outlet 135, so as to ensure that when the gas in the cooking space 113 is discharged, the gas can be quickly discharged from the air outlet 135 to ensure the cooking effect. Among them, the opening width of the avoidance gap 1353 can be smaller than the opening width of the air outlet main body 1351. At this time, the air outlet 135 can clearly distinguish the air outlet main body 1351 and the avoidance gap 1353; it can also be that the opening width of the avoidance gap 1353 is roughly the same as the opening width of the air outlet main body 1351. In this way, there is no obvious boundary between the air outlet main body 1351 and the avoidance gap 1353, which is equivalent to increasing the opening size of the original air outlet 135, and the area where the thermal deformation element 33 is provided can be regarded as the avoidance gap 1353.

[0071] In some embodiments of the present application, the sealing member 31 is provided on the appliance body 10 in a translational manner. The translational direction of the sealing member 31 may be a direction away from or close to the air outlet 135, so that the air outlet 135 is opened when the sealing member 31 is away from the air outlet 135. The sealing member 31 may also be translated on the outer wall surface of the cooking space 113, so that the sealing member 31 can be misaligned with the air outlet 135 and the air outlet 135 is opened. When the sealing member 31 is translated to move away from or close to the air outlet 135, the arrangement of the thermally-sensitive deformable element 33 may refer to the aforementioned embodiment of rotating the sealing member 31 to move away from the air outlet 135, and will not be described in detail here. When the sealing member 31 is translated along the outer wall surface of the cooking space 113, a pushing portion 333 as in the aforementioned embodiment may be provided, and the extension and retraction and folding directions of the pushing portion 333 are substantially the same as the translation direction of the sealing member 31; or, the thermosensitive deformation element 33 may be provided in the air outlet 135, and the pushing portion 333 may be extended outwardly of the air outlet 135 as described above, and at the same time, the surface of the sealing member 31 facing the air outlet 135 may be provided as an inclined surface, and when the pushing portion 333 extends outwardly and pushes the sealing member 31, the pushing portion 333 is abutted against the inclined surface, and at this time, the thrust applied to the sealing member 31 by the pushing portion 333 will separate a component force along the translation direction of the sealing member 31, thereby pushing the sealing member 31 to translate.

[0072] In some embodiments of the present application, the sealing member 31 is rotatably and translationally arranged on the device body 10. In this embodiment, if the sealing member 31 is both rotatably and translationally arranged on the device body 10, two thermo-sensitive deformation elements 33 may be arranged to respectively control the translation and rotation of the sealing member 31, and the deformation temperatures of the two thermo-sensitive deformation elements 33 may be different; or the same thermo-sensitive deformation element 33 may have a deformation mode in two different temperature ranges, so that when the temperature around the thermo-sensitive deformation element 33 reaches different temperature ranges, the sealing member 31 is driven to rotate or translate respectively; or when the thermo-sensitive deformation element 33 is deformed, the sealing member 31 is driven to rotate and translate at the same time.

[0073] In one embodiment of the present application, at least part of the sealing structure 30 is a thermosensitive deformable structure, and the thermosensitive deformable material is deformed by heat to drive the sealing structure 30 to move, thereby changing the conductive area between the air outlet 135 or the air outlet channel 117 and the outside world. Different from the combined structure of the sealing member 31 and the thermosensitive deformable element 33 in the aforementioned embodiment, in this embodiment, the sealing structure 30 is roughly an integral structure, and at least part of the sealing structure 30 is made of thermosensitive deformable material to form a thermosensitive deformable structure. Of course, the sealing structure 30 can be made of thermosensitive deformable material as a whole; in this way, when the sealing structure 30 reaches the thermosensitive temperature, the thermosensitive deformable structure will deform to cause the entire sealing structure 30 to move, thereby changing the opening size of the air outlet 135 or changing the conductive area between the air outlet channel 117 and the outside world.

[0074] In an embodiment of the present application, the appliance body 10 includes a hot air module 15 , and the hot air module 15 is disposed in the cooking space 113 .

[0075] The air fryer 100 further includes a hot air module 15 disposed in the cooking space 113. The hot air module 15 generally includes a fan 151 and a heating element 153. The heating element 153 can be disposed on the blades of the fan 151, or on the air inlet or air outlet of the fan 151, so that the heating element 153 can heat the airflow driven by the fan 151, thereby causing the hot air to flow and circulate in the cooking space 113. Cooking by hot air circulation heating can heat the surface of the food evenly, and the temperature of each position in the cooking space 113 is also relatively consistent. In this way, when the heat-sensitive deformation element 33 is deformed by sensing the temperature in the cooking space 113, the opening and closing state of the air outlet 135 can be better controlled based on the cooking temperature and mode, thereby improving the cooking effect. In addition, when the sealing member 31 needs to be opened outward, the hot air driven by the hot air module 15 can also play an auxiliary role in pushing the sealing member 31, so as to facilitate opening the sealing member 31.

[0076] Please refer to Figure 1 In some embodiments of the present application, the appliance body 10 includes an outer shell 11 and an inner cover 13. The inner cover 13 is arranged inside the outer shell 11, and the inner space of the outer shell 11 is divided into a accommodating space 111 and the cooking space 113. The inner cover 13 is provided with the air outlet 135, and the outer shell 11 is provided with an air outlet 115 connected to the accommodating space 111.

[0077] In this embodiment, the appliance body 10 includes an outer shell 11 and an inner cover 13. In this embodiment, the appliance body 10 includes an outer shell 11 and an inner cover 13. An installation space is formed in the outer shell 11, and the inner cover 13 is separated in the installation space, so that the installation space is divided into an accommodating space 111 and a cooking space 113. The accommodating space 111 can be used to install electronic components such as circuit boards or a driving component for driving the fan 151 of the hot air module 15 to rotate and a heat dissipation fan 151 for dissipating heat from the driving component. The inner cover 13 is provided with an air outlet 135 connecting the accommodating space 111 and the cooking space 113, and the outer shell 11 is provided with an air outlet 115 connecting the cooking space 113, so that the gas discharged from the cooking space 113 through the air outlet 135 can be discharged outward through the accommodating space 111 and the air outlet 115. When a heat dissipation fan 151 is provided in the accommodating space 111, the airflow driven by the heat dissipation fan 151 can also be discharged from the air outlet 115 to improve the heat dissipation efficiency. At this time, the sealing member 31 and the heat-sensitive deformation element 33 are both accommodated in the outer shell 11, which can protect each component and make the air fryer 100 look neat.

[0078] In the embodiment of the present application, the orientation of the air fryer 100 in normal use and placement is used as an example to explain the orientation, and the orientations such as top and bottom are defined based on this. Among them, the inner cover 13 can be separated from the outer shell 11, so that the accommodating space 111 is located above the inner cover 13, and the cooking space 113 is located below the inner cover 13. At this time, the air outlet 135 can be opened on the top surface of the inner cover 13, or in the following embodiment, the inner cover 13 is set as a partially raised structure, and the air outlet 135 is opened on the side wall of the inner cover 13. In this way, when the air outlet 135 does not need to be opened, the sealing member 31 can be made to hang down under the action of gravity to cover the air outlet 135.

[0079] Among them, the utensil body 10 may also include a storage basket 17 for placing food, and an opening connected to the cooking space 113 is opened on the side wall of the outer shell 11, and the storage basket 17 is inserted into the opening; the utensil body 10 can also be set to a flip-cover structure, so that the outer shell 11 includes a pot body and a cover body, and a cooking space 113 is formed in the pot body. The cover body covers the top opening of the pot body, and the inner cover 13 is covered on the surface of the cover body facing the opening of the pot body, and is enclosed with the cover body to form a accommodating cavity.

[0080] Please refer to Figure 2 and Figure 4 In some embodiments of the present application, the inner cover 13 includes a cover shell 131 and a flange 133, the cover shell 131 protrudes toward one side of the accommodating space 111, and includes a top wall 1311 and a surrounding edge 1313 arranged around the top wall 1311, the flange 133 extends from the lower edge of the surrounding edge 1313 to the outside of the cover shell 131, and the air outlet 135 is opened on the surrounding edge 1313.

[0081] In the embodiment of the present application, the orientation of the air fryer 100 in normal use and placement is used as an example for orientation description. In the embodiment, the inner cover 13 is configured as a partially raised structure, including a cover shell 131 raised to one side of the accommodating space 111 and a flange 133 connected to the cover shell 131, the cover shell 131 includes a top wall 1311 and a surrounding edge 1313 arranged around the top wall 1311, the flange 133 extends from the lower edge of the surrounding edge 1313 to the outside of the cover shell 131, and the space formed in the cover shell 131 can be used to install structures such as the hot air module 15. The air outlet 135 is provided on the surrounding edge 1313. At this time, the sealing member 31 extends roughly in the height direction, and may also extend obliquely. When the air outlet 135 needs to be opened, the thermal deformation element 33 can drive the sealing member 31 to move to open the air outlet 135. When the air outlet 135 does not need to be opened, the sealing member 31 will naturally fall down under the action of gravity to cover the air outlet 135, thereby improving the convenience of use.

[0082] In an embodiment of the present application, the air fryer 100 further includes a fragrance module, which is communicated with the cooking space 113 to supply aroma gas to the cooking space 113 .

[0083] In this embodiment, a fragrance module is provided in the air fryer 100. The fragrance module can be a containing structure such as a smoke material box, which can be used to place smoke materials, connect the smoke material box with the cooking space 113, and supply aroma gas to the cooking space 113; wherein the smoke material box can be directly placed in the cooking space 113, or a conducting structure such as an air duct can be provided between the smoke material box and the cooking space 113 to connect the smoke material box and the cooking space 113. In addition, the smoke material can be directly ignited and placed in the smoke material box, or a heating structure can be provided in the fragrance module to heat the smoke material in the smoke material box; both can make the aroma gas generated by the combustion of the smoke material discharged into the cooking space 113. The fragrance module can also be only a guide structure, which is provided on the appliance body 10 and connected with the cooking space 113, so that the fragrance module can be connected with the external aroma gas generating module to introduce the aroma gas generated outside into the cooking space 113.

[0084] The setting of the aroma module can impart the desired aroma substances to the ingredients during the cooking process, so that the ingredients can emit the desired aroma, such as smoky, fruity or other aromas. When the aroma module is activated for aroma, the sealing structure 30 is used to block the air outlet channel 117 or shield the air outlet 135 as much as possible, so that the cross-section of the air outlet channel 117 connecting with the outside is minimized or the opening area of ​​the air outlet 135 is minimized, so as to slow down the emission of aroma gases from the cooking space 113 to the outside, increase the contact time between the aroma substances and the ingredients, and allow more aroma substances to penetrate into the ingredients, so that users can have a better aroma experience when enjoying the ingredients.

[0085] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
