[0081] The present application provides a cooking appliance 100.

[0082] Please refer to Figures 1 to 4 In some embodiments of the present application, the cooking appliance 100 comprises:

[0083] An appliance body 10, a cooking space 111 is formed in the appliance body 10, and an air outlet channel 114 communicating with the cooking space 111 is provided;

[0084] A blocking piece 30, the blocking piece 30 is rotatably arranged in the appliance body 10, and at least part of the blocking piece 30 is arranged in the air outlet channel 114; and

[0085] A wind power module 50, the wind power module 50 is arranged in the appliance body 10, and the wind power module 50 can drive airflow to blow to the blocking piece to drive the blocking piece 30 to rotate and change the cross-sectional area of the air outlet channel 114 communicating with the outside with the change of the cooking process.

[0086] The cooking appliance 100 provided in the present application can be an air fryer, an oven or a steam oven, etc. The cooking appliance 100 comprises an appliance main body 10, a barrier 30 and a wind power module 50. The appliance main body 10 is internally formed with a cooking space 111, and is provided with an air outlet channel 114 in communication with the cooking space 111. The cooking space 111 can be used for placing food materials. At least part of the barrier 30 is rotatably arranged in the air outlet channel 114, and changes the conduction area of the air outlet channel 114 when rotated to different positions. Thus, for cooking modes that need to be tenderly roasted or smoked, or other cooking modes that need to keep the moisture of food materials or keep the cooking space 111 from being in communication or less communication with the outside, the barrier 30 can be placed in a position to largely or completely block the air outlet channel 114, so as to slow down or avoid the gas in the cooking space 111 from being discharged outward, so that the food materials are in a cooking environment with relatively high humidity, thereby reducing the loss of moisture in the food materials. In addition, for cooking modes that need to smoke and roast food materials, the barrier 30 can also be placed in a position to largely or completely block the air outlet channel 114, so that the aroma gas in the cooking space 111 is not easily lost, so that the food materials are in an environment with high concentration of aroma gas during the smoking and roasting process, thereby enabling the food materials to better absorb aroma substances and improving the smoking effect. For the cooking mode of crisp roasting, the barrier 30 can be controlled to rotate to a position to largely conduct the air outlet channel 114, so that the water vapor in the cooking space 111 can be discharged outward through the air outlet channel 114, reducing the moisture of the food materials, thereby achieving the cooking effect of crisp roasting.

[0087] In the present application, the rotation of the barrier 30 is driven by the wind power module 50 through air flow. As shown in Figures 8 to 11 , the windward structure of the barrier 30 and the shielding structure for blocking the air outlet channel 114 can be the same structure; as shown in Figure 3 and Figure 4In some embodiments, the cooking process variation includes adaptive speed variation of the wind force module 50 in response to the state of the food during the cooking process.

[0088] In some embodiments, the cooking process variation includes adaptive speed variation of the wind force module 50 in response to the state of the food during the cooking process.

[0089] In some embodiments, the change in the speed of rotation includes transitioning from a high speed of rotation at the beginning of cooking to a low speed of rotation at the end of cooking to finish the food. For example, when adjusting the degree of crispiness / tenderness, at the beginning of cooking, the food releases a large amount of water vapor, which is just discharged through the large area of the air outlet passage 114, leaving the right amount of water vapor to adjust the degree of crispiness / tenderness, and at the end of cooking, the air outlet passage 114 is just closed or reduced in size, leaving the right amount of water vapor to adjust the degree of crispiness / tenderness. For another example, when flavoring, at the beginning of cooking, the food is mainly cooked and the flavoring material is preheated, which requires a large air speed and a large area of the air outlet passage 114, and at the end of cooking, the flavoring material is just settled on the food through a small air speed or zero air speed, and the air outlet passage 114 is just closed or reduced in size to reduce the leakage of the flavoring material, thereby improving the flavoring effect.

[0090] In some embodiments, the change in the speed of rotation includes transitioning from a high speed of rotation at the beginning of cooking to a medium speed of rotation during cooking to cook the food.

[0091] Of course, any change in the speed of rotation of the air force module 50 (including constant) in response to the change in the state of the food during cooking is within the scope of the present application, and is not listed here.

[0092] In some embodiments, the change in the cooking process includes a change in the temperature in the cooking space 111.

[0093] In this way, the cooking process can be linked to the rate of communication between the gas in the cooking space 111 and the outside, providing a better cooking environment for the food.

[0094] Therefore, it can be understood that the technical scheme of the present application is that the air outlet channel 114 communicating with the cooking space 111 is arranged in the cooking appliance 100, and the movable blocking piece 30 is arranged for controlling the cross-sectional area of the air outlet channel 114 that can communicate with the outside world; the blocking piece 30 is rotatably arranged in the air outlet channel 114, and the air force module 50 is arranged in the cooking appliance 100; the air force module 50 can drive the airflow to blow towards the blocking piece 30, for example, to drive the airflow outside the cooking space 111 to blow towards the blocking piece 30, or to drive the airflow inside the cooking space 111 to flow towards the blocking piece 30, both of which can drive the blocking piece 30 to rotate, so as to control the conduction cross-sectional area of the air outlet channel 114. When it is required to tenderly roast or smoke the food or other cooking modes that do not require exhaust or require a small amount of exhaust, the air outlet channel 114 can be closed to a large extent or completely by the blocking piece, at this time, the water vapor, aroma gas or other gas in the cooking space 111 cannot be discharged or discharged slowly from the air outlet channel 114, so that the cooking space 111 can be kept for a long time, so that the food is in an environment with high humidity or high aroma gas concentration, so as to achieve the purpose of keeping moisture and fully absorbing aroma substances. When it is required to crisp the food or other cooking modes that require exhaust, the blocking piece 30 can be located at a position that makes the air outlet 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 air outlet channel 114. In addition, the rotation angle of the blocking piece 30 can be controlled by controlling the air force of the air force module 50, so as to adjust the conduction cross-sectional size of the air outlet channel 114, so as to be suitable for various different cooking modes. That is, the technical scheme of the present application, the cooking appliance 100 can control the position of the blocking piece 30 by controlling the start-stop state and air force of the air force module 50 according to the change of the cooking process and the use requirement of different cooking modes, so as to adjust the opening degree of the air outlet channel 114, enrich the function of the cooking appliance 100, and improve the cooking effect.

[0095] The present application also provides a cooking appliance 100, wherein the cooking appliance 100 comprises an appliance main body 10, a blocking piece 30 and an air force module 50; the appliance main body 10 is formed with a cooking space 111, and is provided with an air outlet channel 114 communicating with the cooking space 111; the blocking piece 30 is rotatably arranged in the appliance main body 10, and at least part of the blocking piece 30 is arranged in the air outlet channel 114; the air force module 50 is arranged in the appliance main body 10, and the air force module 50 can drive the airflow to blow towards the blocking piece, so as to drive the blocking piece 30 to rotate and change the cross-sectional area of the air outlet channel 114 that communicates with the outside world.

[0096] In this embodiment, the air flow module 50 can drive the air flow to blow towards the blocking piece 30, for example, drive the air flow outside the cooking space 111 to blow towards the blocking piece 30, or drive the air flow inside the cooking space 111 to flow towards the blocking piece 30, both of which can drive the blocking piece 30 to rotate to control the conduction cross-sectional area of the air outlet channel 114. When the food needs to be tenderly roasted or smoked, or other cooking modes that do not require exhaust or require a small amount of exhaust, the air outlet channel 114 can be closed to a large extent or completely by the blocking piece, at this time, the water vapor, aroma gas or other gas in the cooking space 111 cannot or can slowly be discharged from the air outlet channel 114, so that the cooking space 111 can be kept for a long time, and the food can be kept in an environment with high humidity or high aroma gas concentration, so as to achieve the purpose of keeping the food moist and fully absorbing the aroma. When the food needs to be crispy roasted or other cooking modes that require exhaust, the blocking piece 30 can be located at a position that allows the air outlet channel 114 to be opened to a large extent, at this time, the water vapor or other gas in the cooking space 111 can be quickly discharged from the air outlet channel 114. In addition, the rotation angle of the blocking piece 30 can be controlled by controlling the air volume of the air flow module 50, so as to adjust the conduction cross-sectional size of the air outlet channel 114, so as to be suitable for various cooking modes.

[0097] In an embodiment of the present application, the cooking appliance 100 further comprises a flavoring module, which communicates with the cooking space 111 to supply the cooking space 111 with aroma gas; during the flavoring process, the cross-sectional area of the part of the air outlet channel 114 that communicates with the outside is the smallest.

[0098] In this embodiment, the flavoring module is arranged in the cooking appliance 100, which can be a smoking material box or other containing structure, and can be used to place smoking material. The smoking material box communicates with the cooking space 111 to supply the cooking space 111 with aroma gas. The smoking material box can be directly placed in the cooking space 111, or a gas guide pipe or other conduction structure can be arranged between the smoking material box and the cooking space 111 to communicate the smoking material box and the cooking space 111. In addition, the smoking material can be directly ignited and placed in the smoking material box, or a heating structure can be arranged in the flavoring module to heat the smoking material in the smoking material box. Both of which can make the aroma gas generated by the combustion of the smoking material discharged into the cooking space 111. The flavoring module can also be a flow guide structure arranged on the appliance main body 10 and communicating with the cooking space 111, so that the flavoring module can communicate with the aroma gas generating module outside to guide the aroma gas generated outside into the cooking space 111.

[0099] The fragrance imparting module can impart the required fragrance substance to the food material during the cooking process, so that the food material emits the required fragrance, such as a smoked flavor, a fruit flavor or other fragrance. During the process of imparting fragrance by enabling the fragrance imparting module, the blocking piece 30 can largely or completely close the air outlet channel 114, so that the cross-sectional area of the part of the air outlet channel in communication with the outside is minimized, the emission of fragrance gas from the cooking space 111 to the outside can be slowed down, the contact time of the fragrance substance with the food material is increased, more fragrance substance can penetrate into the food material, and therefore the user can have a better fragrance experience when enjoying the food material.

[0100] Please refer to Figure 3 and Figure 4 In an embodiment of the present application, the blocking piece 30 is lapped on the outer wall of the cooking space 111 to shield the air inlet 1315 of the air outlet channel 114.

[0101] In the present embodiment, the blocking piece 30 is arranged at the air inlet 1315 of the air outlet channel 114 to control the opening size of the air inlet 1315. When the cooking space 111 does not need to be exhausted, the shielding part 31 is lapped on the outer wall of the cooking space 111 under the action of gravity and shields the air inlet. The shielding part 31 can be tightly pressed on the outer wall of the cooking space 111 under the action of gravity, which can better shield the air inlet 1315 of the air outlet channel 114 and avoid the problem of serious air leakage due to loosening of the shielding part 31 caused by vibration of the cooking appliance 100 or other factors when the exhaust is not needed. The air inlet 1315 of the air outlet channel 114 can be opened in the top wall 1311 of the cooking space 111, and the shielding part 31 can be pressed on the top wall 1311 of the cooking space 111 under the action of gravity. Alternatively, the air inlet 1315 of the air outlet channel 114 can be opened in the side wall of the cooking space 111, and the rotation axis of the blocking piece 30 is located above the top wall 1311 of the cooking space 111. At this time, the shielding part 31 is tightly pressed on the side wall of the cooking space 111 under the action of gravity to shield the air inlet 1315 of the air outlet channel 114.

[0102] Please refer to Figure 3 and Figure 4 In an embodiment of the present application, the blocking piece 30 includes a shielding part 31 and a windward part 32 connected thereto, and the wind force module 50 includes a first fan 51 arranged outside the cooking space 111. The first fan 51 can drive the airflow to blow towards the windward part 32 and rotate the blocking piece 30.

[0103] In this embodiment, the barrier 30 includes the shielding part 31 and the windward part 32, and a first fan 51 outside the cooking space 111 is provided as the wind power module 50. The first fan 51 can drive the airflow outside the cooking space 111 to blow towards the windward part 32. When the airflow driven by the first fan 51 is large enough to overcome the gravity and other resistance of the barrier 30, the airflow driven by the first fan 51 can drive the barrier 30 to rotate, so as to open the air outlet channel 114 by moving the shielding part 31 away from the air outlet channel 114.

[0104] In this embodiment, the surface of the shielding part 31 facing the air inlet of the air outlet channel 114 is defined as the shielding surface, and the surface of the windward part 32 facing the airflow is defined as the windward surface. The rotation axis of the barrier 30 can be located between the windward part 32 and the shielding part 31, and the windward surface of the windward part 32 and the shielding surface of the shielding part 31 face in opposite directions. Alternatively, the windward part 32 and the shielding part 31 can be located on the same side of the rotation axis. For example, the rotation axis of the barrier 30 can be located on the side of the windward part 32 away from the shielding part 31, or the rotation axis of the barrier 30 can be located on the side of the shielding part 31 away from the windward part 32. In this case, the windward surface of the windward part 32 and the shielding surface of the shielding part 31 face in the same direction. In this way, the barrier 30 can be driven to rotate by the airflow driven by the first fan 51 to adjust the inclination angle of the shielding part 31 in the air outlet channel 114, so as to adjust the size of the conduction cross section of the air outlet channel 114.

[0105] Please refer to Figure 12 and Figure 13 In some embodiments of the present application, the rotation axis of the barrier 30 is located between the windward part 33 and the shielding part 31. In this case, when the windward part 33 is driven to rotate by the wind force, the shielding part 31 can be rotated towards the inside of the cooking space 111 to open the air inlet 1315 of the air outlet channel 114.

[0106] In an embodiment of the present application, the end of the shielding part 31 away from the windward part 32 is rotationally connected to the appliance body 10. In this case, the windward part 32 can be located below the shielding part 31 when the barrier 30 naturally falls under the action of gravity without being driven by the airflow. Alternatively, a torsional spring or other elastic member can be provided to make the windward part 32 located above the shielding part 31 under the condition that the barrier 30 is not driven by the airflow. The first fan 51 can be arranged above the cooking space 111.

[0107] Please refer to Figure 3 and Figure 4 In an embodiment of the present application, the end of the windward part 32 away from the shielding part 31 is rotationally connected to the appliance body 10.

[0108] In the embodiment, the rotating part 33 of the blocking piece 30 is arranged at one end of the windward part 32 away from the shielding part 31, and the rotating part 33 can be a rotating shaft, or can be provided with a rotating shaft hole for passing the rotating shaft, or can be rotatably connected between the blocking piece 30 and the appliance body 10 through a hinge structure, which is not limited herein. The windward part 32 is arranged between the shielding part 31 and the rotating part 33, so as to be arranged outward of the cooking space 111, thereby avoiding being shielded by the structure forming the cooking space 111, and enabling the windward part 32 to be driven by the external airflow driven by the wind power module 50.

[0109] Please refer to Figure 3 and Figure 4 In an embodiment of the present application, the windward part 32 and the shielding part 31 are arranged at an obtuse angle in the counterclockwise direction.

[0110] In the embodiment, the shielding part 31 of the blocking piece 30 can be used to shield the air inlet 1315 connecting the cooking space 111 and the air outlet channel 114, and the air inlet 1315 is located on the side wall of the cooking space 111. In the embodiment, the blocking piece 30 is a bent structure, so that the included angle α between the windward part 32 and the shielding part 31 is an obtuse angle, i.e. 90° < α < 180°; and one end of the windward part 32 away from the shielding part 31 is rotatably connected with the appliance body 10. In this way, the windward part 32 is inclined to the side close to the air outlet channel 114 from the shielding part 31, so that the shielding part 31 has a tendency to move close to the air inlet 1315 of the air outlet channel 114 under the action of gravity, and the shielding part 31 can press the wall surface provided with the air inlet 1315 of the air outlet channel 114.

[0111] Please refer to Figure 3 and Figure 4 In an embodiment of the present application, the included angle α between the windward part 32 and the shielding part 31 satisfies 135° ≤ α < 180°.

[0112] In the embodiment, the included angle α between the windward part 32 and the shielding part 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, the shielding part 31 can be pressed against the region where the air outlet channel 114 is located under the action of gravity, and the included angle between the shielding part 31 and the windward part 32 is not too small, so that the component force for driving the windward part 32 to move in the airflow blowing to the windward part 32 when the shielding part 31 shields the air outlet channel 114 is not too small, and the blocking piece 30 is difficult to be driven to rotate.

[0113] Please refer to Figure 3 and Figure 4In an embodiment of the present application, the hinge position of the windward part 32 and the utensil body 10 is horizontally offset from the blocking part 31, and is located above the cooking space 111.

[0114] In the present embodiment, the blocking part 31 of the barrier 30 is used to shield the air inlet 1315 that communicates the cooking space 111 and the air outlet passage 114, and the air inlet 1315 is located on the side wall of the cooking space 111. In the present embodiment, the rotating part 33 located at the end of the windward part 32 away from the blocking part 31 is located above the cooking space 111. It can be understood that the center of gravity of an object in a free hanging state will naturally fall below the hanging point. That is, the blocking part 31 will have a tendency to rotate close to the lower side of the rotating part 33 under the action of gravity. However, in the present embodiment, the lower side of the rotating part 33 of the barrier 30 is shielded by the structure forming the cooking space 111, so that the blocking part 31 will press the wall surface on which the air inlet 1315 of the air outlet passage 114 is opened under the action of gravity, thereby better shielding the air inlet 1315 when the air inlet 1315 is not opened. It should be noted that the horizontal direction herein refers to the direction from the front wall to the back wall.

[0115] For reference Figures 1 to 4 In an embodiment of the present application, a guide air duct 171 is formed in the utensil body 10, the guide air duct 171 is located outside the cooking space 111, the utensil body 10 is provided with an air outlet 115 that communicates with the guide air duct 171, and the first fan 51 is arranged at the inlet end of the guide air duct 171; the windward part 32 faces the guide air duct 171.

[0116] In the present embodiment, the guide air duct 171 is formed in the utensil body 10. In this way, the airflow driven by the first fan 51 can be guided to flow to the windward part 32 and then flow out from the air outlet 115, thereby avoiding the escape of the airflow driven by the first fan 51, which requires the first fan 51 to rotate at a higher speed to drive the barrier 30 to rotate. In addition, the arrangement position of the first fan 51 can be more flexible by the arrangement of the guide air duct 171, without the need to be directly aligned with the windward part 32, thereby improving the flexibility of the structure arrangement. In some embodiments, the first fan 51 can be used as a cooling fan in the cooking utensil 100, for cooling circuit devices such as circuit boards or the driving module 70 such as a motor in the following embodiments; the first fan 51 drives the airflow to flow through the structure that needs to be cooled, and the airflow can carry away heat and be discharged to the outside from the air outlet 115.

[0117] For reference Figures 1 to 4In an embodiment of the present application, the appliance body 10 comprises a shell 11 and an inner cover 13, the shell 11 is provided with an air outlet 115 of an air outlet channel 114; the inner cover 13 is arranged in the inner part of the shell 11, the upper part of the inner cover 13 forms a containing space 113, and is provided with a flow guide structure 17, the flow guide structure 17 and the inner cover 13 form a flow guide air duct 171, and the first fan 51 is arranged in the containing space 113; the lower part of the inner cover 13 forms a cooking space 111, and the inner cover 13 is provided with an air inlet 1315 of the air outlet channel 114.

[0118] In an embodiment of the present application, the appliance body 10 comprises a shell 11 and an inner cover 13, the shell 11 is provided with an air outlet 115 of an air outlet channel 114; the inner cover 13 is arranged in the inner part of the shell 11, the upper part of the inner cover 13 forms a containing space 113, and is provided with a flow guide structure 17, the flow guide structure 17 and the inner cover 13 form a flow guide air duct 171, and the first fan 51 is arranged in the containing space 113; the lower part of the inner cover 13 forms a cooking space 111, and the inner cover 13 is provided with an air inlet 1315 of the air outlet channel 114.

[0119] It should be noted that in the present embodiment, the first fan 51 is arranged in the containing space 113 and needs to drive air flow to blow into the flow guide air duct 171, at this time, an air guide opening can be formed on the shell 11 to communicate with the containing space 113, or the upper part of the shell 11 can be a spliced structure formed by at least two parts, and the spliced position between the two parts is a non-sealed connection with an air inlet gap, so that external air flow can enter the containing space 113 under the driving of the first fan 51 and flow into the flow guide air duct 171.

[0120] In the present embodiment, the appliance body 10 can further comprise a food placing basket 19, an opening is formed on the side wall of the shell 11 to communicate with the cooking space 111 below the inner cover 13, and the placing basket 19 is inserted into the opening; the appliance body 10 can also be provided as a flip cover structure, so that the shell 11 comprises a pot body and a cover body, the pot body is formed with a cooking space 111, the cover body is arranged on the top opening of the pot body, the inner cover 13 is arranged on the surface of the cover body facing the opening of the pot body, and the inner cover 13 and the cover body form a containing cavity.

[0121] In combination with the aboveFigures 1 to 4 In one embodiment 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 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 air outlet channel 114 is opened at the surrounding edge 1313. At least a portion of the guide air duct 171 is located above the top wall 1311 and the air outlet channel 114.

[0122] In the embodiment of the present application, the orientation of the cooking appliance 100 during normal use and placement is used as an example for description. In this embodiment, the inner cover 13 is configured as a partially raised structure, comprising a housing 131 protruding toward one side of the accommodating space 113 and a flange 133 connected to the housing 131. The housing 131 includes a top wall 1311 and a surrounding edge 1313 extending from the bottom edge of the surrounding edge 1313 toward the outside of the housing 131. The space formed within the housing 131 can be used to mount structures such as the heating module 15. The air outlet channel 114 is opened on the surrounding edge 1313, and the guide air duct 171 is located above the top wall 1311 and the air outlet channel 114. At this time, the blocking member 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 the air outlet channel 114 needs to be opened, the first fan 51 can be made to blow toward the windward portion 32 to rotate the blocking member 30, thereby causing the shielding portion 31 to be misaligned with the air outlet channel 114; when the air outlet channel 114 does not need to be opened, the shielding portion 31 will naturally fall down under the action of gravity to shield the air outlet channel 114, and there is no need for the wind module 50 to blow the shielding portion 31 toward the air outlet channel 114, thereby improving ease of use.

[0123] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the wind module 50 also includes a second fan 53 provided in the cooking space 111. The second fan 53 can drive the air flow inside the cooking space 111 so that part of the airflow flows to the air outlet channel 114. The barrier 30 can rotate under the push of the external airflow and the internal airflow of the cooking space 111.

[0124] In this embodiment, the wind module 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 toward the barrier 30, thereby driving the barrier 30 to rotate and open the air outlet channel 114. The first fan 51 can directly drive the airflow from the side of the shielding portion 31 toward the shielding portion 31, thereby driving the shielding portion 31 to rotate. Alternatively, the surface of the shielding portion 31 facing away from the air outlet channel 114 can be configured as an inclined surface, so that the first fan 51 blows the airflow toward the inclined surface. In this case, the airflow generates a component force along the direction of rotation of the shielding portion 31, thereby driving the shielding portion 31 to rotate. Of course, in the following embodiment, a windward portion 32 can also be provided on the barrier 30, so that the first fan 51 blows the airflow toward the windward portion 32, thereby driving the barrier 30 to rotate.

[0125] The second fan 53 can drive external airflow into the cooking space 111 and flow within the cooking space 111. It is understood that when airflow exists within the cooking space 111, part of the airflow will flow toward the air outlet passage 114, thereby applying a thrust to the shielding portion 31 located at the air outlet passage 114. This thrust can also be used to assist in driving the blocking member 30 to rotate to open the air outlet passage 114.

[0126] In this embodiment, the barrier 30 can be rotated and opened when the first fan 51 and the second fan 53 are driven simultaneously. If two motors are provided to drive the first fan 51 and the second fan 53 respectively, the control of whether the barrier 30 is opened or closed can be achieved by simultaneously increasing or decreasing the speed of the first fan 51 and the second fan 53, or by adjusting the speed of one of the fans to adjust the thrust exerted on the barrier 30. Alternatively, the rotation of the barrier 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 outlet channel 114 does not need to be opened, only the second fan 53 can be turned on. When internal hot air heating is required and the air outlet channel 114 needs to be opened, both the first fan 51 and the second fan 53 can be turned on simultaneously. In addition, the barrier 30 can be rotated by only the first fan 51 or the second fan 53. For example, only the first fan 51 or the second fan 53 can be turned on to drive the barrier 30 to rotate and open the air outlet channel 114. The opening size of the air outlet channel 114 can be controlled by controlling the rotational speeds 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 air outlet channel 114 is controlled by simultaneously increasing or decreasing the rotational speeds of the first fan 51 and the second fan 53.

[0127] 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 is limited by the cooking space 111, while the diameter of the first fan 51 is not limited. In this way, when the first fan 51 and the second fan 53 rotate at the same torque and speed, the wind power generated by the first fan 51 is greater than the wind power generated by the second fan 53, and the rotation of the barrier 30 is mainly driven by the first fan 51. Among them, the first fan 51 can be used as a heat dissipation fan to dissipate heat for the cooking appliance 100, so as to avoid overheating of the device outside the cooking space 111 during cooking. At this time, the airflow in the heat dissipation air duct can not only dissipate heat for the appliance body 10, but also blow the barrier 30 to adjust the gas flow in the cooking space 111, which simplifies the structure and improves the user experience.

[0128] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the appliance body 10 further comprises a driving module 70, the driving module 70 is arranged outside the top of the cooking space 111, the driving shaft 71 of the driving module 70 penetrates 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.

[0129] In the present embodiment, the appliance body 10 further comprises a driving module 70, the driving module 70 is arranged in the accommodating space 113, the driving module 70 can be a driving motor, and the output shaft of the driving motor is used as the driving shaft 71; the driving module 70 can also be a combination of a driving motor and a transmission mechanism, and the transmission mechanism can be a worm gear transmission mechanism, a gear and rack transmission mechanism, a gear transmission mechanism, a belt transmission mechanism or a combination of at least two transmission mechanisms; the output end of the transmission structure is arranged as an output shaft. The output shaft of the driving module 70 penetrates the air inlet of the inner 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. The output shaft can be driven to rotate by the driving device, thereby driving the first fan 51 and the second fan 53 to rotate. In this way, when the air outlet channel 114 does not need to be opened, the first fan 51 and the second fan 53 both operate at a lower speed, and there is not enough airflow to blow the barrier 30 to rotate and open; when the air outlet channel 114 needs to be opened, the speed of the first fan 51 and the second fan 53 can be increased, so that the barrier 30 is opened under the thrust of the external airflow and the internal airflow. In addition, the airflow driven by the first fan 51 can also dissipate heat for the driving module 70, so as to carry away the heat generated by the continuous opening of the driving module 70 during the operation of the cooking appliance 100 and dissipate it outward through the airflow guide duct 171.

[0130] The first fan 51 and the second fan 53 are sleeved 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 be cooled in time; and the number of the driving modules 70 arranged in the cooking appliance 100 is reduced, and the internal structure of the cooking appliance 100 is simplified.

[0131] In the embodiment, the first fan 51 can be a vortex fan, the second fan 53 can be an axial fan, and the fan blades of the first fan 51 and the second fan 53 are arranged in opposite directions.

[0132] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, the air force module 50 includes the second fan 53 arranged in the cooking space 111, the second fan 53 can drive the air flow in the cooking space 111, and part of the air flow flows to the air outlet channel 114.

[0133] In the embodiment, the part of the blocking member 30 used to shield the air outlet channel 114 is defined as the shielding part 31, and the air force module 50 further includes the second fan 53 arranged in the cooking space 111, wherein the cooking space 111 can be a closed space, and the second fan 53 can drive the air in the cooking space 111 to circulate and flow. The cooking space 111 can also be a non-enclosed space, for example, a vent is arranged on the side wall of the cooking space 111, or there is a gap between the structures surrounding the cooking space 111, so that the second fan 53 can 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 in the cooking space 111, part of the air flow will flow to the air outlet channel 114, so as to apply a pushing force to the shielding part 31 in the air outlet channel 114; when the rotating speed of the second fan 53 is large enough to make the air flow to the air outlet channel 114 have sufficient air force, the blocking member 30 can be driven to rotate to open the air outlet channel 114.

[0134] In some embodiments, the second fan 53 is part of a hot air module, and the heating module 15 in the cooking space 111 is provided with at least one heating element 151 located in the cooking space 111, wherein the at least one heating element 151 is arranged in the air inlet direction or the air outlet direction of the second fan 53 and can heat the air flow driven by the second fan 53, and the second fan 53 needs to be turned on to form hot air during cooking; at this time, the speed of the second fan 53 can be reduced without opening the air outlet channel 114, so as to avoid that the air flow driven by the second fan 53 blows open the blocking piece 30; the speed of the second fan 53 is increased when the air outlet channel 114 needs to be opened, so as to open the blocking piece 30. Alternatively, in some embodiments, the air force module 50 further includes the first fan 51 arranged outside the cooking space 111, so that the air flow driven by the second fan 53 and flowing to the air outlet channel 114 only plays an auxiliary role, and the blocking piece 30 needs to be driven when the first fan 51 is turned on at the same time.

[0135] The heating element 151 and the second fan 53 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 and thus reducing heat loss. The heating element 151 can be arranged as a heating wire, a heating coil, electromagnetic heating, a hot air assembly, infrared heating, microwave heating or other heating structures, and one or at least two heating structures can be arranged. In addition, the heating element 151 is arranged in the air inlet direction or the air outlet direction of the second fan 53, for example, the heating element 151 can be arranged on the fan blade of the second fan 53, or arranged at the air inlet of the second fan 53 or the air outlet of the second fan 53, so as to heat the air flow driven by the second fan 53 to form hot air. The hot air flowing in the cooking space 111 can transfer heat to the food to cook the food, and the circulating flow of the hot air makes the food evenly heated.

[0136] It should be noted that in the embodiments of the present application, the heating module 15 of the cooking appliance 100 can 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 at the side wall of the cooking space 111, so as to improve the heating efficiency of the food in the cooking space 111 and make the upper and lower surfaces or the circumferential side of the food evenly heated, thereby improving the cooking effect.

[0137] Please refer to Figure 5 and Figure 6 In an embodiment of the present application, at least one side surface of the blocking piece 30 is provided with at least one rib 34.

[0138] In the embodiment, the barrier 30 shields the air inlet 1315 of the air outlet passage 114; at least one side surface of the barrier 30 is provided with the rib 34, which can be arranged on the surface opposite to the air inlet 1315 or on the surface away from the air inlet 1315; the rib 34 can be arranged in one row or at least two rows; when the rib 34 is arranged in at least two rows, the ribs 34 can be arranged in the same direction or some of the ribs 34 can be arranged in a cross manner; due to the arrangement of the rib 34, the barrier 30 is not easy to bend and deform in the extension direction of the rib 34, thereby improving the structural strength and stability of the barrier 30.

[0139] Please refer to Figure 5 In an embodiment of the present application, at least one rib 34 extends along the length direction of the barrier 30.

[0140] And / or, at least one rib 34 extends along the width direction of the barrier 30.

[0141] In the embodiment, the length direction of the barrier 30 is the direction perpendicular to the rotation axis of the barrier 30, and the width direction of the barrier 30 is the direction parallel to the rotation axis of the barrier 30. At least one rib 34 can extend along the length direction of the barrier 30, at this time, the rib 34 improves the structural strength of the barrier 30 in the length direction, so that the barrier 30 is not easy to bend and deform in the length direction. In some embodiments, the barrier 30 includes the windward part 32 and the shielding part 31 arranged at an angle, at this time, the length direction of the barrier 30 is also the arrangement direction of the windward part 32 and the shielding part 31, and the arrangement of the rib 34 can improve the stability of the angle between the windward part 32 and the shielding part 31.

[0142] In some embodiments, at least one rib 34 can also extend along the width direction of the barrier 30, so that the barrier 30 is not easy to bend and deform in the width direction, and the barrier 30 can be tightly attached to the outer wall of the cooking space 111 to tightly attach and shield the air outlet passage 114, thereby achieving a better sealing effect. When the barrier 30 is provided with at least two ribs 34, two of the ribs 34 can extend along the length direction and the width direction of the barrier 30, respectively, thereby improving the overall structural strength of the barrier 30 and keeping the structural form of the barrier 30 stable. It should be noted that when the barrier 30 is provided with at least two ribs 34, one of the ribs 34 can extend along the length direction or the width direction of the barrier 30, and the extension direction of the other rib 34 is not limited.

[0143] In addition, the rib 34 can extend to the edge of the barrier 30 or near the edge, and the rib 34 can abut the outer wall of the cooking space 111. In this way, due to the arrangement of the rib 34, there is a gas leakage gap 35 between the barrier 30 and the outer wall of the cooking space 111, which communicates with the cooking space 111. In this way, the barrier 30 can avoid completely closing the cooking space 111 when the air outlet channel 114 is blocked, so that the barrier 30 is difficult to be driven to open under the action of the negative pressure inside the cooking space 111.

[0144] In some embodiments, at least a first air permeable part is provided on the barrier 30 or between the barrier 30 and the outer wall of the cooking space 111, and the first air permeable part is used to communicate the cooking space 111 with the outside atmosphere. In this embodiment, the first air permeable part can be a gas leakage hole 36, a gap 37 or the like structure provided on the barrier 30. In this case, when the barrier 30 is arranged between the air outlet channels 114 or covers the air inlet 1315 of the air outlet channel 114, the first air permeable part can play a role of pressure relief, avoiding the negative pressure on the side of the barrier 30 facing the cooking space 111, which makes it difficult to drive the barrier 30 by the airflow. In some embodiments, if the barrier 30 can abut the outer wall of the cooking space 111 to cover the air inlet 1315 of the air outlet channel 114, at least one of the surface of the barrier 30 and the outer wall of the cooking space 111 can be provided with an abutting part, so that the barrier 30 and the outer wall of the cooking space 111 are spaced apart to form a gas leakage gap 35. In addition, the barrier 30 can not completely cover the air inlet, so that the edge of the barrier 30 and the edge of the air inlet 1315 are spaced apart to form a gas leakage gap 35. In this way, the same pressure relief effect can be achieved, avoiding the cooking space 111 being completely closed when the barrier 30 blocks the air outlet channel 114, so that the barrier 30 is difficult to be driven to open under the action of the negative pressure inside the cooking space 111.

[0145] In some embodiments, at least a second air permeable part is provided between the barrier 30 and the outer wall of the cooking space 111, and the second air permeable part is used to communicate the cooking space 111 with the outside atmosphere.

[0146] In the embodiment, the blocking piece 30 can abut against the outer wall of the cooking space 111 to cover the air inlet 1315 of the air outlet channel 114, and the second air permeable part is located between the blocking piece 30 and the outer wall of the cooking space 111. At least one of the surface of the blocking piece 30 and the outer wall of the cooking space 111 can be provided with an abutting part, so that part of the blocking piece 30 is spaced apart from the outer wall of the cooking space 111 to form the air leakage gap 35, or the surface of the blocking piece 30 or the outer wall of the cooking space can be recessed to form an air leakage groove. In this way, the second air permeable part can play a role in pressure relief, so that the blocking piece 30 is not completely closed by the cooking space 111 when the air outlet channel 114 is covered, thereby avoiding the blocking piece 30 being difficult to be driven to open due to the negative pressure inside the cooking space 111.

[0147] Please refer to Figure 6 and Figure 7 In an embodiment of the present application, the second air permeable part includes an air leakage gap 35.

[0148] And / or, the blocking piece 30 is provided with an air leakage hole 36.

[0149] In the embodiment, the blocking piece 30 and the edge of the air inlet 1315 of the air outlet channel 114 can have an air leakage gap 35 that communicates with the cooking space 111 as the second air permeable part, or the blocking piece 30 can be provided with an air leakage hole 36 that communicates with the cooking space 111 as the second air permeable part. In this way, the blocking piece 30 can be prevented from completely closing the cooking space 111 when covering the air outlet channel 114, thereby avoiding the blocking piece 30 being difficult to be driven to open due to the negative pressure inside the cooking space 111.

[0150] In some embodiments of the present application, the surface of the blocking piece 30 facing the outer wall of the cooking space 111 is provided with at least one abutting part, and the abutting part abuts against the outer wall of the cooking space 111 to form an air leakage gap 35 between the blocking piece 30 and the outer wall of the cooking space 111. Specifically, a part of the surface of the blocking piece 30 facing the air outlet channel 114 can be provided with a protruding rib, a protruding block or other abutting parts, so that the abutting parts abut against the outer wall of the cooking space 111. In this way, an air leakage gap 35 can be formed between the edge of the air outlet channel 114 and the blocking piece 30 when the blocking piece 30 covers the air outlet channel 114.

[0151] In some embodiments of the present application, the surface of the blocking piece 30 facing the air inlet 1315 is provided with an air leakage groove. The air leakage groove can be formed by subtractive machining on the surface of the blocking piece 30, or the surface of the blocking piece 30 facing the air inlet 1315 can be recessed to form an air leakage groove on the other surface, and the other surface of the blocking piece 30 is provided with a rib 34 or other structures.

[0152] In some embodiments, the surface of the blocking piece 30 towards the air inlet 1315 is provided with at least one abutting portion, which abuts against the outer wall of the cooking space 111, so that the blocking piece 30 and the outer wall of the cooking space 111 have an air leakage gap 35 therebetween. The abutting portion can be a rib 34 or a protrusion, and when the abutting portion abuts against the outer wall of the cooking space 111, the position without the abutting portion forms the air leakage gap 35 with the outer wall of the cooking space 111, so that the blocking piece 30 is not affected by the negative pressure inside the cooking space 111 and is easy to be driven to open.

[0153] In some embodiments of the present application, the outer wall of the cooking space 111 is provided with an air leakage groove towards the blocking piece 30.

[0154] In some embodiments of the present application, the outer wall of the cooking space 111 is provided with an air leakage groove towards the blocking piece 30.

[0155] In some embodiments of the present application, the outer wall of the cooking space 111 is provided with an air leakage groove towards the blocking piece 30.

[0156] Please refer to Figure 5 and Figure 7 , the edge of the blocking piece 30 is provided with a notch 37. In this way, the blocking piece 30 is more easily blown and rotated, avoiding the need to increase the power of the air blower 50 due to the excessive weight of the blocking piece 30, thereby avoiding larger noise and reducing energy consumption. The notch 37 can be provided on one side of the blocking piece 30, or notches 37 can be provided on both sides of the blocking piece 30 to balance the mass of the blocking piece 30. In addition, the notch 37 can also achieve the air permeation function, avoiding the blocking piece 30 being difficult to be driven to open due to the effect of the negative pressure inside the cooking space 111.

[0157] Please refer to Figures 8 to 11 In some embodiments of the present application, the air outlet channel 114 has oppositely arranged upper and lower side walls, one end of the blocking piece 30 is rotatably connected to the upper side wall, and the distance between the blocking piece 30 and the lower side wall changes when the blocking piece 30 rotates.

[0158] In this embodiment, the air outlet channel 114 has an upper side wall and a lower side wall arranged opposite along the height direction, and the upper end of the blocking piece 30 is rotationally connected to the upper side wall. When the blocking piece 30 freely falls, the blocking piece 30 is spaced apart from the lower side wall. In addition, the lower side wall gradually extends towards the upper side wall along the air outlet direction of the air outlet channel 114. In this way, when the blocking piece 30 rotates in the air outlet channel 114, the distance between the blocking piece 30 and the lower side wall changes, thereby changing the size of the conduction cross section of the air outlet channel 114. At this time, the position of the blocking piece 30 can be controlled according to different cooking requirements by controlling the start-stop state and the wind power of the wind power module 50.

[0159] In some embodiments, at least part of the lower side wall gradually inclines upward along the extension direction of the air outlet channel 114, and one end of the blocking piece 30 is rotationally connected to the upper side wall. In this way, when the blocking piece 30 rotates, the distance between the blocking piece 30 and the lower side wall will change accordingly. The structure is simple. In addition, as the wind power of the wind power module 50 increases, the distance between the blocking piece 30 and the lower side wall will first decrease and then increase, so that the cross-sectional area of the opened air outlet channel 114 will first decrease and then increase. Therefore, the wind power of the wind power module 50 can be controlled according to actual cooking requirements. For example, if a cooking mode with small wind speed and air permeability is required, the wind power module 50 can be operated at a low gear. For a cooking mode requiring medium wind power and reducing the conduction area of the air outlet channel 114, the wind power module 50 can be operated at a medium gear to rotate the blocking piece 30 by a preset angle and reduce the conduction area of the air outlet channel 114. When high wind power is required for baking and the exhaust effect needs to be improved, the wind power module 50 can be operated at a high gear to blow air at a high speed to drive the blocking piece 30 to rotate at a large angle and increase the conduction area of the air outlet channel 114, thereby improving the exhaust effect.

[0160] The present application also provides a cooking appliance 100, which comprises:

[0161] an appliance main body 10, in which a cooking space 111 is formed, and which is provided with an air outlet channel 114 communicating with the cooking space 111 and the outside;

[0162] a blocking piece 30 movably arranged in the appliance main body 10, at least part of which is arranged in the air outlet channel 114; and

[0163] a wind power module 50 arranged in the appliance main body 10, which can drive air flow to blow towards the blocking piece 30 to move the blocking piece 30 and change the cross-sectional area of the part of the air outlet channel 114 communicating with the outside.

[0164] In the embodiment, the cooking appliance 100 is provided with an air outlet channel 114 communicating with the cooking space 111, and a movable barrier 30 is arranged to control the cross-sectional area of the air outlet channel 114 that can communicate with the outside. The movement mode of the barrier 30 can be rotation, translation, or a combination of rotation and translation, which is not limited herein.

[0165] Meanwhile, the cooking appliance 100 is provided with a wind power module 50. The wind power module 50 can drive airflow to blow against the barrier 30 to drive the barrier to move, for example, to drive airflow outside the cooking space 111 to blow against the barrier 30, or to drive airflow inside the cooking space 111 to flow to the barrier 30, both of which can drive the barrier 30 to move, thereby controlling the conduction cross-sectional area of the air outlet channel 114.

[0166] In this way, when the food needs to be tenderly roasted or smoked, or other cooking modes that do not require exhaust or require a small amount of exhaust, the air outlet channel 114 can be closed to a large extent or completely by the barrier, at which time the water vapor, aroma gas or other gas in the cooking space 111 cannot be discharged or discharged slowly from the air outlet channel 114, so as to keep the cooking space 111 for a long time, so that the food is in an environment with high humidity or high aroma gas concentration, thereby achieving the purpose of moisture retention and sufficient absorption of aroma substances. When the food needs to be crispy roasted or other cooking modes that require exhaust, the barrier 30 can be located at a position that allows the air outlet channel 114 to be opened to a large extent, at which time the water vapor or other gas in the cooking space 111 can be quickly discharged from the air outlet channel 114. In addition, the size of the wind power of the wind power module 50 can be controlled to control the moving distance or rotation angle of the barrier 30, so as to adjust the conduction cross-sectional size of the air outlet channel 114 to adapt to various different cooking modes. That is, the technical solution of the present application can control the position of the barrier 30 by controlling the start-stop state and the wind power of the wind power module 50 according to the change of the cooking process and the use requirements of different cooking modes, so as to adjust the opening degree of the air outlet channel 114, enrich the functions of the cooking appliance 100, and improve the cooking effect.

[0167] In some embodiments, the wind power module 50 includes a first fan 51 arranged outside the cooking space 111 and a second fan 53 arranged inside the cooking space 111, and the first fan 51 can drive airflow to move the barrier 30.

[0168] In this embodiment, the air flow module 50 includes a first fan 51 and a second fan 53. The first fan 51 can drive the air flow outside the cooking space 111 to the blocking piece 30, so as to drive the blocking piece 30 to move to change the conduction area of the air outlet channel 114. The second fan 53 is arranged in the cooking space 111 and can form a hot air module in cooperation with the heating module 15. The heating module 15 heats the air flow, so that the hot air flows in the cooking space 111 to uniformly heat the food materials at different positions. In some embodiments, when there is air flow inside the cooking space 111, part of the air flow will flow to the air outlet channel 114, so as to apply a pushing force to the shielding part 31 located at the air outlet channel 114. The pushing force can also be used to assist in driving the blocking piece 30 to rotate to open the air outlet channel 114.

[0169] In some embodiments, the first fan 51 can be used as a heat dissipation fan to dissipate heat for the cooking appliance 100, so as to avoid overheating of the devices outside the cooking space 111 during cooking. At this time, the air in the heat dissipation air duct can not only dissipate heat for the appliance body 10, but also blow the blocking piece 30 to adjust the air flow in the cooking space 111, which simplifies the structure and improves the user experience.

[0170] The above description is only the preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made according to the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
