[0072] The utility model provides an air fryer 100.

[0073] Please refer to Figures 1 to 4 In some embodiments of the present application, the air fryer 100 includes:

[0074] A device body 10, wherein a cooking space 111 is formed in the device body 10, and an air flow channel 114 is provided to connect the cooking space 111 with the outside;

[0075] A windshield 30, an end of which is rotatably connected to the device body 10, and at least a portion of the windshield 30 is disposed in the airflow channel 114, and the windshield 30 can change the shielding area of ​​the airflow channel 114 when rotating; and

[0076] The airflow driving component 50 is arranged on the appliance body 10. The airflow driving component 50 can drive the airflow to blow toward the wind shield 30, so as to drive the wind shield 30 to rotate according to the change of the cooking process and adjust the shielding area of ​​the wind shield 30 on the airflow channel 114.

[0077] The air fryer 100 proposed in the present application includes a device body 10, a wind shield 30 and an airflow driving assembly 50. A cooking space 111 is formed in the device body 10, and an airflow channel 114 connected to the cooking space 111 is arranged on the device body 10; the cooking space 111 can be used to place food, at least a part of the wind shield 30 is rotatably arranged in the airflow channel 114, and the conduction area of ​​the airflow channel 114 changes when it is rotated to different positions. In this way, for cooking modes that require tender roasting or smoking and other cooking modes that require maintaining the moisture of ingredients or keeping the cooking space 111 disconnected or less connected to the outside, the wind shield 30 can be placed in a position that largely or completely blocks the airflow channel 114, so as to slow down or prevent the gas in the cooking space 111 from being discharged outward, so that the ingredients are placed in a cooking environment with relatively high humidity, thereby reducing the loss of moisture in the ingredients; in addition, for cooking modes that require smoking ingredients, the wind shield 30 can also be placed in a position that largely or completely blocks the airflow channel 114, so that the aroma gas in the cooking space 111 is not easily lost, so that the ingredients are placed in an aroma gas environment with a high concentration during the smoking process, so that the ingredients can better absorb the aroma substances and improve the smoking effect. For cooking modes such as crispy roasting, the wind shield 30 can be controlled to rotate to a position that makes the airflow channel 114 open to a large extent, so that the water vapor in the cooking space 111 can be discharged outward through the airflow channel 114, reducing the moisture of the ingredients, thereby achieving a crispy roasting cooking effect.

[0078] In the embodiment of the present application, the end of the wind shield 30 is rotatably connected to the device body 10, and the wind shield 30 is driven to rotate by the airflow drive assembly 50 through the airflow. Figures 8 to 11 As shown, the windward structure of the wind shield 30 and the shielding structure for blocking the airflow channel 114 can be the same structure; Figure 3 and Figure 4As shown, the windshield 30 includes a connected windward structure and a shielding structure. In addition, the airflow driving component 50 can be arranged on the inner side of the cooking space 111 to drive the airflow inside the cooking space 111. During this process, part of the airflow in the cooking space 111 will flow to the airflow channel 114 and push the windshield 30 to rotate. In some embodiments, when the airflow driving component 50 is used to drive the airflow inside the cooking space 111, it can also cooperate with the heating component 15 to form a hot air module. The heating component 15 heats the airflow so that the hot air flows in the cooking space 111 and heats all positions of the food uniformly. In some embodiments, the airflow driving component 50 can also be arranged on the outer side of the cooking space 111 to drive the airflow outside the cooking space 111 to blow toward the windshield 30 and drive the windshield 30 to rotate to adjust the conduction degree of the airflow channel 114. In addition, the airflow driving assembly 50 may also include a first fan 51 disposed outside the cooking space 111 and a second fan 53 disposed inside the cooking space 111. The first fan 51 may drive the airflow outside the cooking space 111 to blow toward the wind shield 30, and the second fan 53 may drive the airflow inside the cooking space 111 to flow and blow toward the wind shield 30, so that the wind shield 30 rotates under the action of the airflow outside and inside the cooking space 111. In the embodiment of the present application, the rotation angle of the wind shield 30 may also be controlled by adjusting the wind force of the airflow driving assembly 50, thereby controlling the degree of conduction of the airflow channel 114. In some embodiments, the airflow guided by the first fan 51 has a horizontal speed due to the volute rectification, that is, it can be blown horizontally toward the wind shield 30; and the airflow guided by the second fan 53 circulates internally in the cooking space 111. Due to the effect of the wind guide cover, the circulating airflow caused by the movement of the second fan 53 is parallel or nearly parallel to the wind shield 30 at a position close to the wind shield 30, so the first fan 51 is more suitable for blowing the wind shield 30 to move.

[0079] In some embodiments, the change of the cooking process includes adaptively changing the rotation speed of the airflow driving assembly 50 as the state of the food changes during the cooking process.

[0080] In some embodiments, the change in speed includes: transitioning from a high wind speed at the beginning of cooking to quickly cook the food to a low wind speed for coloring at the end of cooking. For example, when it is necessary to adjust the crispy / tender roasting, at the beginning of cooking, the food will release a large amount of water vapor, and the excessive water vapor will be discharged through the large area of ​​the air flow channel 114, leaving an appropriate amount of water vapor to adjust the degree of crispy / tender roasting. At the end of cooking, the conduction area of ​​the air flow channel 114 is closed or reduced, leaving an appropriate amount of water vapor to adjust the degree of crispy / tender roasting. To give another example, when adding fragrance, at the beginning of cooking, the food is mainly cooked and the fragrance material is preheated, which requires a high wind speed and a large area of ​​the air flow channel 114. At the end of cooking, the fragrance substances are deposited on the food through a low wind speed or zero wind speed, and the conduction area of ​​the air flow channel 114 is closed or reduced to reduce the leakage of the fragrance substances, thereby improving the fragrance effect.

[0081] In some embodiments, the change in rotation speed includes: transitioning from a high wind speed for dehumidification (such as frozen food) at the beginning of cooking to a medium wind speed for cooking during the cooking process.

[0082] Of course, any adaptive rotational speed change (including constant) of the airflow drive assembly 50 as the state of the food changes during the cooking process is within the protection scope of the present application and is not listed here one by one.

[0083] In some embodiments, the change in the cooking process includes a change in the temperature within the cooking space 111 .

[0084] With such an arrangement, the cooking process can be linked with the rate at which the gas in the cooking space 111 communicates with the outside world, thereby providing a better cooking environment for food.

[0085] Therefore, it can be understood that the technical solution of the present application is to set an air flow channel 114 connected to the cooking space 111 in the air fryer 100, and set a movable wind shield 30 for controlling the cross-sectional area of ​​the air flow channel 114 that can be connected to the outside world; the wind shield 30 is rotatably set in the air flow channel 114, and an air flow driving component 50 is set in the air fryer 100; the air flow driving component 50 can drive the air flow to blow toward the wind shield 30, for example, drive the air flow outside the cooking space 111 to blow toward the wind shield 30, and can also drive the air flow inside the cooking space 111 to flow toward the wind shield 30, and can drive the wind shield 30 to rotate to adjust the shielding area of ​​the air flow channel 114 by the wind shield 30, thereby controlling the conductive cross-sectional area of ​​the air flow channel 114. When it is necessary to tender-roast or smoke the food or other cooking modes that do not require exhaust or require a small amount of exhaust, the airflow channel 114 can be largely or completely closed by the wind shield. At this time, the water vapor, aroma gas or other gas in the cooking space 111 cannot be discharged from the airflow channel 114 or is discharged slowly, so that the food can be retained in the cooking space 111 for a long time, so that the food is in an environment with high humidity or high concentration of aroma gas, which can achieve the purpose of moisturizing and fully absorbing aroma substances. When it is necessary to crisp roast the food or adopt other cooking modes that require exhaust, the wind shield 30 can be placed in a position that makes the airflow channel 114 open to a large extent. At this time, the water vapor or other gas in the cooking space 111 can be quickly discharged from the airflow channel 114. In addition, the wind force of the airflow drive component 50 can be controlled to control the rotation angle of the wind shield 30, thereby adjusting the conduction cross-sectional size of the airflow channel 114 to adapt to a variety of different cooking modes. That is, according to the technical solution of the present application, the air fryer 100 can control the position of the wind shield 30 by controlling the start and stop states of the airflow drive assembly 50 and the wind force according to changes in the cooking process and the usage requirements of different cooking modes, thereby adjusting the opening degree of the airflow channel 114, enriching the functions of the air fryer 100 and improving the cooking effect.

[0086] The present application also proposes an air fryer 100, wherein the air fryer 100 includes an appliance body 10, a wind shield 30 and an airflow driving assembly 50; a cooking space 111 is formed in the appliance body 10, and an airflow channel 114 connected to the cooking space 111 is opened; an end of the wind shield 30 is rotatably connected to the appliance body 10, and at least a portion of the wind shield 30 is arranged in the airflow channel 114; the airflow driving assembly 50 is arranged in the appliance body 10, and the airflow driving assembly 50 can drive the airflow to blow toward the wind shield, so as to drive the wind shield 30 to rotate and change the cross-sectional area of ​​the airflow channel 114 connected to the outside world.

[0087] In this embodiment, the airflow driving component 50 can drive the airflow to blow toward the windshield 30, for example, drive the airflow outside the cooking space 111 to blow toward the windshield 30, or drive the airflow inside the cooking space 111 to flow toward the windshield 30, and can drive the windshield 30 to rotate to control the conduction cross-sectional area of ​​the airflow channel 114. When the food needs to be tender-roasted or smoked, or other cooking modes that do not require exhaust or require a small amount of exhaust, the airflow channel 114 can be largely or completely closed by the windshield. At this time, the water vapor, aroma gas or other gas in the cooking space 111 cannot be discharged from the airflow channel 114 or is discharged slowly, so that the food can be retained in the cooking space 111 for a long time, so that the food is in an environment with high humidity or high aroma gas concentration, which serves the purpose of moisturizing and fully absorbing aroma substances. When the food needs to be crispy roasted or other cooking modes that require exhaust are adopted, the windshield 30 can be placed in a position where the airflow channel 114 is largely open, and the water vapor or other gas in the cooking space 111 can be quickly discharged from the airflow channel 114. In addition, the wind force of the airflow driving assembly 50 can be controlled to control the rotation angle of the wind shield 30, thereby adjusting the conduction cross-sectional size of the airflow channel 114 to adapt to a variety of different cooking modes.

[0088] In one embodiment of the present application, the air fryer 100 also includes a fragrance module, which is connected to the cooking space 111 to supply aroma gas to the cooking space 111; during the fragrance process, the airflow driving assembly 50 stops moving, and the cross-sectional area of ​​the airflow channel 114 that is connected to the outside is minimized.

[0089] 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 111, and supply aroma gas to the cooking space 111; wherein, the smoke material box can be directly placed in the cooking space 111, or a conducting structure such as an air duct can be provided between the smoke material box and the cooking space 111 to connect the smoke material box and the cooking space 111. 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 111. The fragrance module can also be a flow guide structure, which is provided on the appliance body 10 and connected with the cooking space 111, 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 111.

[0090] 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 to perform aroma assignment, the airflow driving component stops moving, so that the wind shield 30 can largely or completely close the airflow channel 114, so that the cross-sectional area of ​​the part of the airflow channel connected to the outside is minimized, which can slow down the emission of aroma gases from the cooking space 111, 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.

[0091] Please refer to Figure 3 and Figure 4 In one embodiment of the present application, the wind shield 30 is overlapped with the outer wall of the cooking space 111 to shield the air inlet 1315 of the air flow channel 114.

[0092] In this embodiment, the wind shield 30 is disposed at the air inlet 1315 of the air flow channel 114 to control the opening size of the air inlet 1315. When the cooking space 111 does not need to be vented, the shielding portion 31 overlaps the outer wall of the cooking space 111 under the action of gravity and shields the air inlet; the shielding portion 31 can be pressed tightly against the outer wall of the cooking space 111 under the action of gravity to better shield the air inlet 1315 of the air flow channel 114, thereby avoiding serious air leakage caused by the loosening of the shielding portion 31 due to vibration of the air fryer 100 or other factors when exhaust is not required. Among them, the air inlet 1315 of the air flow channel 114 can be opened on the top wall 1311 of the cooking space 111, and the shielding portion 31 can be pressed on the top wall 1311 of the cooking space 111 under the action of gravity; or the air inlet 1315 of the air flow channel 114 can be opened on the side wall of the cooking space 111, and the rotation axis of the wind shield 30 is located above the top wall 1311 of the cooking space 111. At this time, the shielding portion 31 is pressed against the side wall of the cooking space 111 under the action of gravity to shield the air inlet 1315 of the air flow channel 114.

[0093] Please refer to Figure 3 and Figure 4 In one embodiment of the present application, the hinge position between the wind shield 30 and the appliance body 10 is staggered with the air inlet 1315 in the horizontal direction and is located above the cooking space 111.

[0094] In this embodiment, the windshield 30 is used to shield the air inlet 1315 connecting the cooking space 111 and the air flow channel 114, and the air inlet 1315 is located on the side wall of the cooking space 111. In this embodiment, the rotating part 33 at one end of the windshield 30 is located above the cooking space 11, and is staggered with the air inlet 1315 in the horizontal direction. It can be understood that when an object is in a free hanging state, its center of gravity will naturally fall below the hanging point; that is, the windshield 30 will have a tendency to rotate close to the bottom of the rotating part 33 under the action of gravity, and because the bottom of the rotating part 33 of the windshield 30 in the embodiment of the present application is blocked by the structure forming the cooking space 111, the windshield 30 will press the wall surface with the air inlet 1315 of the air flow channel 114 under the action of gravity, so that when the air inlet 1315 does not need to be opened, it can better shield the air inlet 1315. It should be noted that the horizontal direction here refers to the direction from the front wall surface to the rear wall surface.

[0095] Please refer to Figure 3 and Figure 4 In one embodiment of the present application, the wind shield 30 includes a shielding portion 31 and a windward portion 32 connected to each other, the shielding portion 31 is separated from the airflow channel 114, and the airflow driving component 50 includes a first fan 51 arranged outside the cooking space 111, and the first fan 51 can drive the airflow to blow toward the windward portion 32 and cause the wind shield 30 to rotate.

[0096] In this embodiment, the wind shield 30 includes a shielding portion 31 and a windward portion 32, and a first fan 51 located outside the cooking space 111 is provided as an airflow driving component 50. The first fan 51 can drive the external airflow of the cooking space 111 to blow toward the windward portion 32. When the airflow driven by the first fan 51 is large and the wind force is sufficient to overcome the gravity and other resistances of the wind shield 30 itself, the airflow driven by the first fan 51 can drive the wind shield 30 to rotate, thereby allowing the shielding portion 31 to move away from the airflow channel 114 and open the airflow channel 114.

[0097] Among them, the rotation axis of the wind shield 30 can be located at the end of the windward portion 32 away from the shielding portion 31, or the rotation axis of the wind shield 30 can be located at the end of the shielding portion 31 away from the windward portion 32. When the first fan 51 drives the airflow to blow toward the windward surface, the wind shield 30 can be rotated to adjust the inclination angle of the shielding portion 31 in the airflow channel 114, so as to adjust the size of the conducting cross-section of the airflow channel 114.

[0098] In some embodiments, the rotation axis of the wind shield 30 can also be located between the windward portion 33 and the shielding portion 31. At this time, when the windward portion is acted upon by wind force to rotate the wind shield 30, the shielding portion 31 can rotate toward the inside of the cooking space 111 to open the air inlet 1315 of the airflow channel 114.

[0099] Please refer to Figure 3 and Figure 4 In one embodiment of the present application, one end of the windward portion 32 away from the shielding portion 31 is rotatably connected to the device body 10 .

[0100] In this embodiment, the rotating part 33 of the windshield 30 is arranged at one end of the windward part 32 away from the shielding part 31. The rotating part 33 may be a rotating shaft, or may be provided with a rotating shaft hole for passing the rotating shaft. Of course, the windshield 30 may also be rotatably connected to the appliance body 10 through an articulated structure such as a hinge, which is not limited here. The windward part 32 is arranged between the shielding part 31 and the rotating part 33, so that the windward part 32 is conveniently protruded from the cooking space 111, thereby preventing the windward part 32 from being blocked by the structure forming the cooking space 111, and allowing the windward part 32 to be driven by the external airflow driven by the airflow driving component 50.

[0101] Please refer to Figure 3 and Figure 4 In one embodiment of the present application, the windward portion 32 and the shielding portion 31 are arranged at an obtuse angle along the counterclockwise direction.

[0102] In the embodiment of the present application, the shielding portion 31 of the wind shield 30 can be used to shield the air inlet 1315 connecting the cooking space 11 and the air flow channel 114, and the air inlet 1315 is located on the side wall of the cooking space 111. In the present embodiment, the wind shield 30 is a bent structure, so that the angle α formed between the windward portion 32 and the shielding portion 31 is an obtuse angle, that is, 90°<α<180°; and the end of the windward portion 32 away from the shielding portion 31 is rotatably connected to the appliance body 10, so that the windward portion 32 is deflected from the shielding portion 31 to the side close to the air flow channel 114, so that the shielding portion 31 has a tendency to move closer to the air inlet 1315 of the air flow channel 114 under the action of gravity, so that the shielding portion 31 can press the wall surface where the air inlet 1315 of the air flow channel 114 is opened.

[0103] Please refer to Figure 3 and Figure 4 In one embodiment of the present application, the angle α between the windward portion 32 and the shielding portion 31 satisfies 135°≤α<180°.

[0104] In the present embodiment, the angle α formed between the windward portion 32 and the shielding portion 31 is 135°≤α<180°; wherein, α can be 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, 175° or any value between 135° and 180°; at this time, it can not only satisfy that the shielding portion 31 can press the area where the airflow channel 114 is located under the action of gravity, but also avoid that the angle between the shielding portion 31 and the windward portion 32 is too small, resulting in a small component of the airflow blowing toward the windward portion 32 when the shielding portion 31 blocks the airflow channel 114 for driving the windward portion 32 to move, making it difficult to drive the windshield member 30 to rotate.

[0105] In one embodiment of the present application, one end of the shielding portion 31 away from the windward portion 32 is rotatably connected to the appliance body 10. The windward portion 32 can be located below the shielding portion 31 when the wind shielding member 30 is naturally drooped without being driven by the airflow; or an elastic member such as a torsion spring can be provided to enable the windward portion 32 of the wind shielding member 30 to be located above the shielding portion 31 without being driven by the airflow, and the first fan 51 can be provided above the cooking space 111.

[0106] Combined with reference Figures 1 to 4 In one embodiment of the present application, a guide air duct 171 is formed in the appliance body 10, and the guide air duct 171 is located outside the cooking space 111. The appliance body 10 is provided with an air outlet 115 connected to the guide air duct 171, and the first fan 51 is arranged at the inlet end of the guide air duct 171; the windward portion 32 faces the guide air duct 171.

[0107] In this embodiment, a guide air duct 171 is formed in the appliance body 10. Such a configuration can be used to guide the airflow driven by the first fan 51 to fully flow to the windward portion 32 and then flow out from the air outlet 115, so as to avoid the airflow driven by the first fan 51 from escaping, which requires the first fan 51 to rotate at a higher speed in order to drive the wind shield 30 to rotate. In addition, the configuration of the guide air duct 171 can also make the setting position of the first fan 51 more flexible, without the need to directly align it with the windward portion 32, thereby improving the flexibility of the structural configuration. In some embodiments, the first fan 51 can be used as a heat dissipation fan in the air fryer 100, and is used to dissipate heat for circuit devices such as circuit boards in the air fryer 100, or for drive modules 70 such as motors in the following embodiments; the first fan 51 drives the airflow to flow through the structure that needs to be dissipated, and the airflow can take away the heat and discharge it to the outside from the air outlet 115.

[0108] Combined with reference Figures 1 to 4In one embodiment of the present application, the appliance body 10 includes a shell 11 and an air guide cover 13, the shell 11 is provided with an air outlet 115 of the air flow channel 114; the air guide cover 13 is separated inside the shell 11, and a accommodating space 113 is formed above the air guide cover 13, and a guide structure 17 is provided, the guide structure 17 and the air guide cover 13 are enclosed to form the guide air duct 171, and the first fan 51 is arranged in the accommodating space 113; the cooking space 111 is formed below the air guide cover 13, and the air guide cover 13 is provided with an air inlet 1315 of the air flow channel 114.

[0109] In the embodiment of the present application, the orientation is described based on the direction in which the air fryer 100 is normally used and placed, and the orientations such as top and bottom are defined based on this. In the present embodiment, the appliance body 10 includes a housing 11 and an air guide cover 13. An installation space is formed in the housing 11. The air guide cover 13 is separated in the installation space, so that the installation space is divided into a receiving space 113 located above the air guide cover 13 and a cooking space 111 located below the air guide cover 13. A guide structure 17 is also provided in the receiving space 113. The guide structure 17 and at least part of the surface of the air guide cover 13 facing away from the cooking space 111 are enclosed to form a guide air duct 171. The guide structure 17 can be a baffle, a cylinder or other structures. An air inlet 1315 connecting the cooking space 111 and the air flow channel 114 is provided on the air guide cover 13. An air outlet 115 connecting the air flow channel 114 is provided on the housing 11. A first fan 51 is provided in the receiving space 113 to drive the air flow into the guide air duct 171. Such an arrangement enables the first fan 51, the wind shield 30, the heating assembly 15 and other structures in the air fryer 100 to be accommodated in the housing 11, so as to protect the various components and make the air fryer 100 look neat.

[0110] It should be noted that, in the present embodiment, the first fan 51 is arranged in the accommodating space 113, and needs to drive the airflow to blow into the guide air duct 171. At this time, an air guide port connected to the accommodating space 113 can be opened on the outer shell 11, or the upper shell of the outer shell 11 can be a splicing structure formed by at least two parts, and the splicing position of the two parts is a non-sealed connection with an air inlet gap, so that the external airflow can enter the accommodating space 113 and flow into the guide air duct 171 under the drive of the first fan 51.

[0111] Among them, the utensil body 10 may also include a storage basket 19 for placing food, and an opening connected to the cooking space 111 below the air guide cover 13 is opened on the side wall of the outer shell 11, and the storage basket 19 is inserted into the opening; the utensil body 10 can also be set to a flip structure, so that the outer shell 11 includes a pot body and a cover body, a cooking space 111 is formed in the pot body, the cover body covers the top opening of the pot body, and the air guide cover 13 is covered on the surface of the cover body facing the pot body opening, and is enclosed with the cover body to form a accommodating cavity.

[0112] Combined with reference Figures 1 to 4 In one embodiment of the present application, the air guide cover 13 includes a cover shell 131 and a flange 133, the cover shell 131 protrudes toward one side of the accommodating space 113, 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, the air inlet 1315 of the airflow channel 114 is opened at the surrounding edge 1313, and at least part of the guide air duct 171 is located above the top wall 1311 and the airflow channel 114.

[0113] 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 air guide cover 13 is configured as a partially raised structure, including a cover shell 131 raised to one side of the accommodating space 113 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 heating component 15. The airflow channel 114 is opened on the surrounding edge 1313, and the guide air duct 171 is located above the top wall 1311 and the airflow channel 114. At this time, the wind shield 30 extends roughly in the height direction, so that the shielding portion 31 is located on the side of the surrounding edge 1313, and the windward portion 32 is arranged higher than the shielding portion 31 and is located in the guide air duct 171; with such a configuration, when it is necessary to open the airflow channel 114, the first fan 51 can be made to blow toward the windward portion 32 to rotate the wind shield 30, thereby causing the shielding portion 31 to be misaligned with the airflow channel 114; when there is no need to open the airflow channel 114, the shielding portion 31 will naturally fall down under the action of gravity to shield the airflow channel 114, and there is no need for the airflow driving assembly 50 to blow the shielding portion 31 toward the airflow channel 114, thereby improving ease of use.

[0114] Please refer to Figure 1 and Figure 2In some embodiments of the present application, the airflow driving assembly 50 also includes a second fan 53 disposed in the cooking space 111, and the second fan 53 can drive the air flow inside the cooking space 111 so that part of the airflow flows to the airflow channel 114, and the wind shield 30 can rotate under the impetus of the external airflow and the internal airflow of the cooking space 111.

[0115] In this embodiment, the airflow driving assembly 50 includes a first fan 51 and a second fan 53. The first fan 51 can drive the external airflow of the cooking space 111 to flow toward the wind shield 30, thereby driving the wind shield 30 to rotate to open the airflow channel 114. The first fan 51 can directly drive the airflow to blow from the side of the shielding portion 31 toward the shielding portion 31 to drive the shielding portion 31 to rotate, or the surface of the shielding portion 31 away from the airflow channel 114 can be set as an inclined surface, so that the first fan 51 blows the airflow toward the inclined surface, and the airflow will generate a component force along the rotation direction of the shielding portion 31 to push the shielding portion 31 to rotate. Of course, in the following embodiment, a windward portion 32 can be set on the wind shield 30, so that the first fan 51 blows the airflow toward the windward portion 32 to drive the wind shield 30 to rotate.

[0116] The second fan 53 can drive the air in the cooking space 111 to flow. It can be understood that when there is airflow inside the cooking space 111, part of the airflow will flow to the airflow channel 114, so that a thrust can be applied to the shielding portion 31 located at the position of the airflow channel 114, and the thrust can also be used to assist in driving the wind shield 30 to rotate to open the airflow channel 114.

[0117] In this embodiment, the wind shield 30 can be turned on when the first fan 51 and the second fan 53 are driven at the same time. If two motors are provided to drive the first fan 51 and the second fan 53 respectively, the control of whether the wind shield 30 is turned on or off can be to increase or decrease the rotation speed of the first fan 51 and the second fan 53 at the same time, or to adjust the rotation speed of one of the fans, so as to adjust the thrust of the wind shield 30; or, the rotation of the wind shield 30 can be controlled by controlling the start and stop of the first fan 51 and the second fan 53. For example, when only internal hot air heating is required and the air flow channel 114 does not need to be opened, only the second fan 53 can be opened; when internal hot air heating is required and the air flow channel 114 needs to be opened, the first fan 51 and the second fan 53 can be opened at the same time. In addition, the wind shield 30 can be driven to rotate only by the first fan 51 or the second fan 53. For example, only the first fan 51 or the second fan 53 is opened to drive the wind shield 30 to rotate and open the air flow channel 114. The opening size of the air flow channel 114 can be achieved by controlling the rotation speed of the first fan 51 and the second fan 53. In some embodiments, such as in an air fryer, the first fan 51 and the second fan 53 are connected to the drive shaft of the same motor. In this case, the opening size of the airflow channel 114 is controlled by simultaneously increasing or decreasing the rotation speeds of the first fan 51 and the second fan 53.

[0118] In some embodiments of the present application, the diameter of the first fan 51 is greater than the diameter of the second fan 53. Since the second fan 53 is arranged in the cooking space 111, its diameter will be limited by the cooking space 111, while the diameter of the first fan 51 is not limited in this way. In this way, when the first fan 51 and the second fan 53 rotate at the same torque and speed, the wind force generated by the first fan 51 is greater than the wind force generated by the second fan 53, and the rotation of the wind shield 30 is mainly driven by the first fan 51. That is, the wind in the heat dissipation duct can not only dissipate heat for the appliance body 10, but also blow the wind shield 30 to adjust the gas flow in the cooking space 111, simplifying the structure and improving the user experience.

[0119] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the appliance body 10 also includes a driving module 70, which is disposed on the outer side of the top of the cooking space 111, and the driving shaft 71 of the driving module 70 passes through the top wall 1311 of the cooking space 111, and the first fan 51 and the second fan 53 are both sleeved on the driving shaft 71 of the driving module 70.

[0120] In this embodiment, the appliance body 10 further includes a driving module 70, which is disposed in the accommodating space 113. The driving module 70 may be a driving motor, and the output shaft of the driving motor is used as the driving shaft 71. The driving module 70 may also be a combination of a driving motor and a transmission mechanism, and the transmission mechanism may be a worm gear transmission mechanism, a rack and pinion transmission mechanism, a gear transmission mechanism, a belt transmission mechanism, or a combination of at least two sets of transmission mechanisms. The output end of the transmission structure is set as an output shaft. The output shaft of the driving module 70 is inserted into the vent of the air guide cover 13, and the first fan 51 located above the cooking space 111 and the second fan 53 located below the top wall 1311 of the cooking space 111 are both sleeved on the output shaft, and the output shaft can be driven by the driving device to rotate, thereby driving the first fan 51 and the second fan 53 to rotate. With such a configuration, when the airflow channel 114 does not need to be opened, the first fan 51 and the second fan 53 both operate at a relatively low speed, and there is not enough airflow to blow toward the wind shield 30 to rotate and open the wind shield 30; when the airflow channel 114 needs to be opened, the speeds of the first fan 51 and the second fan 53 can be increased, so that the wind shield 30 is opened under the thrust of the external airflow and the internal airflow. In addition, with such a configuration, the airflow driven by the first fan 51 can also dissipate heat for the drive module 70, so as to take away the heat generated by the continuous opening of the drive module 70 during the operation of the air fryer 100 and dissipate it outward through the guide air duct 171.

[0121] The first fan 51 and the second fan 53 are both mounted on the driving shaft 71 of the driving module 70, so that the first fan 51 and the second fan 53 can be started and stopped synchronously, so that the cooking module can dissipate heat in time; and the number of driving modules 70 in the air fryer 100 is reduced, simplifying the internal structure of the air fryer 100.

[0122] In this embodiment, the first fan 51 may be configured as a vortex fan, and the second fan 53 may be configured as an axial flow fan.

[0123] Please refer to Figure 1 and Figure 2 In one embodiment of the present application, the airflow driving component 50 includes a second fan 53 disposed in the cooking space 111 , and the second fan 53 can drive the airflow in the cooking space 111 to flow and make part of the airflow flow to the airflow channel 114 .

[0124] In this embodiment, the part of the wind shield 30 used to shield the air flow channel 114 is defined as the shielding portion 31, and the air flow driving assembly 50 further includes a second fan 53 disposed in the cooking space 111, wherein the cooking space 111 may be a closed space, and the second fan 53 may drive the air inside the cooking space 111 to circulate. Alternatively, the cooking space 111 may be a non-enclosed space, for example, a vent is provided on the side wall of the cooking space 111, or a gap is provided between the structures enclosing the cooking space 111, so that the second fan 53 may drive the external air flow to flow into the cooking space 111 and flow in the cooking space 111. It can be understood that when there is air flow inside the cooking space 111, part of the air flow will flow to the air flow channel 114, so that a thrust can be applied to the shielding portion 31 located in the air flow channel 114; when the speed of the second fan 53 is high so that the air flow to the air flow channel 114 has sufficient wind force, the wind shield 30 may be driven to rotate to open the air flow channel 114.

[0125] In some embodiments, the second fan 53 is a part of the hot air module, and the heating assembly 15 in the cooking space 111 is provided with at least one heating element 151 located in the cooking space 111, wherein at least one of the heating elements 151 is provided in the air inlet direction or the air outlet direction of the second fan 53, and can heat the airflow driven by the second fan 53. The second fan 53 needs to be turned on to form hot air during the cooking process; at this time, when it is not necessary to open the airflow channel 114, the speed of the second fan 53 can be reduced to prevent the airflow driven by the second fan 53 from blowing the wind shield 30 open; when it is necessary to open the airflow channel 114, the speed of the second fan 53 is increased to play the role of opening the wind shield 30. Alternatively, in some embodiments, the airflow drive assembly 50 further includes a first fan 51 provided outside the cooking space 111, so that the airflow driven by the second fan 53 and flowing to the airflow channel 114 only plays an auxiliary role, and the wind shield 30 can be driven to rotate only when the first fan 51 is turned on at the same time.

[0126] The heating element 151 is combined with the second fan 53 to form a hot air module; on the one hand, the heating element 151 is located in the cooking space 111, and can directly heat the food in the cooking space 111, reducing the heat transfer path, thereby reducing heat loss. The heating element 151 can be set as a heating wire, a heating coil, electromagnetic heating, a hot air component, infrared heating, microwave heating or other heating structures, and one heating structure can be set, or at least two heating structures can be set. In addition, the heating element 151 is set in the wind inlet direction or the wind outlet direction of the second fan 53. For example, the heating element 151 can be set on the fan blade of the second fan 53, or it can be set at the air inlet of the second fan 53 or the air outlet of the second fan 53 to heat the airflow driven by the second fan 53 to form hot air. The hot air flows in the cooking space 111, so that the heat can be transferred to the food to cook the food, and the hot air circulates so that the food is heated evenly everywhere.

[0127] It should be noted that, in the embodiment of the present application, the heating assembly 15 of the air fryer 100 may further include other heating elements 151, such as a heating element 151 arranged at the bottom of the cooking space 111, or a heating element 151 arranged on the side wall of the cooking space 111, etc., so as to improve the heating efficiency of the food inside the cooking space 111, and make the upper and lower surfaces or the surrounding sides of the food evenly heated, thereby improving the cooking effect.

[0128] Please refer to Figure 5 and Figure 6 In one embodiment of the present application, at least one rib 34 is protrudingly provided on at least one side surface of the wind shield 30 .

[0129] In the present embodiment, the state in which the wind shield 30 shields the air inlet 1315 of the air flow channel 114 is used for explanation; ribs 34 are provided on at least one side surface of the wind shield 30, and the ribs 34 can be provided on the surface opposite to the air inlet 1315, or on the surface away from the air inlet 1315; only one rib 34 can be provided, or at least two ribs 34 can be provided. When at least two ribs 34 are provided, the ribs 34 can be arranged in the same direction, or some of the ribs 34 can be arranged crosswise; due to the provision of the ribs 34, the wind shield 30 is not easy to bend and deform in the extension direction of the ribs 34, thereby improving the structural strength and stability of the wind shield 30.

[0130] Please refer to Figure 5 In one embodiment of the present application, at least one of the ribs 34 extends along the length direction of the wind shield 30;

[0131] And / or, at least one of the ribs 34 extends along the width direction of the wind shielding member 30 .

[0132] In this embodiment, the direction perpendicular to the rotation axis of the windshield 30 is the length direction of the windshield 30, and the direction parallel to the rotation axis of the windshield 30 is the width direction of the windshield 30. Among them, at least one rib 34 can be extended along the length direction of the windshield 30. In this case, the rib 34 improves the structural strength of the windshield 30 in the length direction, so that the windshield 30 is not easy to bend and deform in the length direction. In some embodiments, the windshield 30 includes a windward portion 32 and a shielding portion 31 arranged at an angle. In this case, the length direction of the windshield 30 is also the arrangement direction of the windward portion 32 and the shielding portion 31. The provision of the rib 34 can improve the stability of the angle formed by the windward portion 32 and the shielding portion 31.

[0133] In some embodiments, at least one rib 34 may be extended in the width direction of the windshield 30, so that the windshield 30 is not easily bent or deformed in the width direction, ensuring that the windshield 30 can be close to the outer wall of the cooking space 111, so as to be close to and shield the airflow channel 114, and achieve a better sealing effect. When the windshield 30 is provided with at least two ribs 34, two of the ribs 34 may be extended along the length direction and the width direction of the windshield 30, respectively, to improve the overall structural strength of the windshield 30 and maintain the stability of the structural form of the windshield 30. It should be noted that when the windshield 30 is provided with at least two ribs 34, one of the ribs 34 may be extended along the length direction or the width direction of the windshield 30, and the extension direction of the other ribs 34 is not limited.

[0134] In addition, the ribs 34 can be extended to the edge or adjacent to the edge of the wind shield 30, and can be made to abut against the outer wall of the cooking space 111. Thus, due to the provision of the ribs 34, an air leakage gap 35 connecting the wind shield 30 and the outer wall of the cooking space 111 can be provided. This provision can prevent the cooking space 111 from being completely closed when the wind shield 30 blocks the air flow channel 114, thereby causing the wind shield 30 to be difficult to be driven open due to the negative pressure inside the cooking space 111.

[0135] In some embodiments, there is at least one first air permeable portion on the windshield 30 or between the windshield 30 and the outer wall of the cooking space 111, and the first air permeable portion is used to connect the cooking space 111 with the outside atmosphere. In this embodiment, the first air permeable portion can be a structure such as an air leakage hole 36 or a notch 37 opened on the windshield 30. At this time, if the windshield 30 is separated between the airflow channels 114 or covers the air inlet 1315 of the airflow channel 114, the first air permeable portion can play a role in pressure relief, avoiding the generation of negative pressure in the space on one side of the windshield 30 facing the cooking space 111, which makes it difficult for the windshield 30 to be driven by the airflow. In some embodiments, if the windshield 30 can abut against the outer wall of the cooking space 111 to cover the air inlet 1315 of the airflow channel 114, an abutting portion can be provided on at least one of the surface of the windshield 30 and the outer wall of the cooking space 111, so that a partial area of ​​the windshield 30 is spaced from the outer wall of the cooking space 111 to form an air leakage gap 35, or the windshield 30 does not completely cover the air inlet 1315 so that a space is provided between one side edge of the windshield and the edge of the air inlet 1315 to form an air leakage gap 35. Such a setting can also play a role in pressure relief, avoiding the cooking space 111 from being completely closed when the windshield 30 covers the airflow channel 114, thereby causing the windshield 30 to be difficult to be driven to open due to the negative pressure inside the cooking space 111.

[0136] In some embodiments, there is at least one second air permeable portion between the wind shield 30 and the outer wall of the cooking space 111, and the second air permeable portion is used to connect the cooking space 111 with the outside atmosphere.

[0137] In this embodiment, the wind shield 30 can be in contact with the outer wall of the cooking space 111 to cover the air inlet 1315 of the air flow channel 114. The second air permeable portion is located between the wind shield 30 and the outer wall of the cooking space 111. An abutment portion may be provided on at least one of the surface of the wind shield 30 and the outer wall of the cooking space 111, so that a partial area of ​​the wind shield 30 is spaced apart from the outer wall of the cooking space 111 to form an air leakage gap 35. Alternatively, an air leakage groove may be provided on the surface of the wind shield 30 or the outer wall of the cooking space. With such a configuration, the second air permeable portion can be used to relieve pressure, thereby preventing the cooking space 111 from being completely closed when the wind shield 30 blocks the air flow channel 114, thereby causing the wind shield 30 to be difficult to be driven open due to the negative pressure inside the cooking space 111.

[0138] Please refer to Figure 6 and Figure 7 In one embodiment of the present application, the second air permeable portion includes an air leakage gap 35;

[0139] And / or, the wind shield 30 is provided with an air leakage hole 36 .

[0140] In the present embodiment, an air leakage gap 35 connecting to the cooking space 111 can be provided between the wind shield 30 and the edge of the air inlet 1315 of the air flow channel 114 as a second air permeable portion, or an air leakage hole 36 connecting to the cooking space 111 can be provided on the wind shield 30 as a second air permeable portion; such an arrangement can avoid the cooking space 111 being completely closed when the wind shield 30 blocks the air flow channel 114, thereby causing the wind shield 30 to be difficult to be driven open due to the negative pressure inside the cooking space 111.

[0141] In some embodiments of the present application, at least one abutting portion is convexly provided on the surface of the wind shield 30 facing the outer wall of the cooking space 111, and the abutting portion abuts against the outer wall of the cooking space 111, so that there is an air leakage gap 35 between the wind shield 30 and the outer wall of the cooking space 111. Specifically, a convex rib, a bump or other abutting portion may be convexly provided on a partial area of ​​the surface of the wind shield 30 facing the air flow channel 114, so that the abutting portion abuts against the outer wall of the cooking space 111; thereby, when the wind shield 30 shields the air flow channel 114, an air leakage gap 35 may be formed between the edge of the air flow channel 114 and the wind shield 30.

[0142] In some embodiments of the present application, an air leakage groove is provided on the surface of the wind shield 30 facing the air inlet 1315; wherein, the air leakage groove can be formed directly on the surface of the wind shield 30 by means of subtractive processing or the like, or the surface of the wind shield 30 facing the air inlet 1315 of the air flow channel 114 can be concavely provided on the surface on the other side to form an air leakage groove, and correspondingly, a convex structure such as ribs 34 is formed on the other side surface of the wind shield 30.

[0143] In some embodiments, at least one abutting portion is convexly provided on the surface of the wind shield 30 facing the air inlet 1315, and the abutting portion abuts against the outer wall of the cooking space 111, so that there is an air leakage gap 35 between the wind shield 30 and the outer wall of the cooking space 111. The abutting portion may be a rib 34 or a convex point, etc. When the abutting portion abuts against the outer wall of the cooking space 111, the position where the abutting portion is not provided forms an air leakage gap 35 with the outer wall of the cooking space 111, so as to prevent the wind shield 30 from being difficult to be driven to open due to the negative pressure inside the cooking space 111.

[0144] In some embodiments of the present application, an air leakage groove is provided on the surface of the outer wall of the cooking space 111 facing the wind shield 30;

[0145] And / or, at least one abutment portion is protruded from a surface of the outer wall of the cooking space 111 facing the wind shield 30 , and the abutment portion abuts against the wind shield 30 to form an air leakage gap between the wind shield 30 and the outer wall of the cooking space 111 .

[0146] In this embodiment, the second air permeable portion is formed between the wind shield 30 and the outer wall of the cooking space 111 by forming a gas leakage groove on the outer wall of the cooking space 111, which is connected to the air inlet 1315. When the wind shield 30 is covered on the air inlet 1315, a passage for connecting the cooking space 111 with the atmosphere is formed at the position of the gas leakage groove. In addition, abutting portions such as ribs 34 and bosses may be convexly provided on the outer wall of the cooking space 111, and when the wind shield 30 is covered on the air inlet 1315, it abuts against the abutting portion of the outer wall of the cooking space 111, thereby forming a gas leakage gap 35 connected to the air inlet 1315 around the abutting portion. In this way, the pressure relief effect can be achieved, ensuring that the wind shield 30 will not be difficult to be driven to open due to the negative pressure inside the cooking space 111.

[0147] Please refer to Figure 5 and Figure 7 , a notch 37 is provided at the edge of the wind shield 30. This arrangement can make the wind shield 30 easier to be blown and rotated, avoid the wind shield 30 being too heavy and causing the need to increase the power of the airflow drive component 50, thereby avoiding loud noise and reducing energy consumption. Among them, the notch 37 can be provided only on one side of the wind shield 30, or the notches 37 can be provided on both sides of the wind shield 30 that are opposite to each other, so that the mass of the wind shield 30 is balanced. In addition, the notch 37 can also realize the ventilation function, avoiding the wind shield 30 from being difficult to be driven to open due to the negative pressure inside the cooking space 111.

[0148] Please refer to Figures 8 to 11 In some embodiments of the present application, the airflow channel 114 has an upper side wall and a lower side wall that are arranged opposite to each other, and the end of the wind shield 30 is rotatably connected to the upper side wall, and the distance between the wind shield 30 and the lower side wall changes when the wind shield 30 rotates.

[0149] In this embodiment, the airflow channel 114 has an upper side wall and a lower side wall that are relatively arranged in the height direction. At this time, the upper end of the wind shield 30 is rotatably connected to the upper side wall; when the wind shield 30 hangs freely, the wind shield 30 and the lower side wall are spaced apart; in addition, the lower side wall gradually extends toward the upper side wall along the air outlet direction of the airflow channel 114; in this way, when the wind shield 30 rotates in the airflow channel 114, the distance between the wind shield 30 and the lower side wall changes, thereby changing the size of the conductive cross-section of the airflow channel 114. At this time, the position of the wind shield 30 can be controlled by controlling the start and stop state and wind force of the airflow drive component 50 according to different cooking needs.

[0150] In some embodiments, at least a portion of the lower side wall gradually tilts upward along the extension direction of the airflow channel 114, and the end of the wind shield 30 is rotatably connected to the upper side wall. In this arrangement, when the wind shield 30 rotates, the distance between the wind shield 30 and the lower side wall will change accordingly, and the structure is simple. And as the wind force of the airflow driving assembly 50 increases, there will be a trend that the distance between the wind shield 30 and the lower side wall first decreases and then increases, so that the cross-sectional area of ​​the open airflow channel 114 first decreases and then increases; therefore, the wind force of the airflow driving assembly 50 can be controlled according to actual cooking needs. For example, if a lower wind speed is required for baking and a cooking mode is required for ventilation, the airflow driving assembly 50 can be operated at a lower gear; for some cooking modes that require medium wind force for baking and need to reduce the conduction area of ​​the airflow channel 114, the airflow driving assembly 50 can be operated at a medium gear to rotate the wind shield 30 by a preset angle to reduce the conduction area of ​​the airflow channel 114; when baking is required at a higher wind force and the exhaust effect needs to be improved, the airflow driving assembly 50 can be operated at a higher gear, and the airflow with a higher wind speed drives the wind shield 30 to rotate at a larger angle to increase the conduction area of ​​the airflow channel 114, thereby improving the exhaust effect.

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.
