[0070] Below, the air fryer 100 provided according to some embodiments of the present application will be described with reference to Figures 1 to 9

[0071] In an embodiment according to the present application, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , an air fryer 100 is proposed, which comprises: an appliance body 110; a pot body 120, which is removably arranged in the appliance body 110, the pot body 120 being provided with a cooking cavity 121; a hot air assembly 150, which is arranged in the appliance body 110 and is used for delivering hot air to the cooking cavity 121; and a heating element 130, which is arranged in the appliance body 110 and is located outside the pot body 120, the heating element 130 and the hot air assembly 150 being located at different sides of the cooking cavity 121 respectively, at least a part of the heating element 130 being capable of moving relative to the appliance body 110 to approach or move away from the cooking cavity 121.

[0073] Since the hot air assembly 150 can input hot air into the cooking cavity 121, the hot air can circulate and flow in the cooking cavity 121, and at the same time, the heating element 130 can assist in heating the cooking cavity 121, thereby facilitating the acceleration of the cooking speed of the food materials and the shortening of the cooking time. It can be understood that after the food materials are cooked, the pot body 120 is taken out of the appliance body 110 to facilitate the taking out of the cooked food materials.​

[0074] The hot air assembly 150 and the heating element 130 are respectively located at different sides of the cooking cavity 121, i.e., heat the cooking cavity 121 at different positions, which is beneficial to improve the uniformity of the heating of the food in the cooking cavity 121 and improve the cooking effect of the air fryer 100.

Since the heating member 130 is connected with the second transmission member 143, the second transmission member 143 can drive the heating member 130 to move when moving, so as to make the heating member 130 close to or away from the cooking cavity 121.

[0088] Specifically, when the air fryer 100 starts the multi-heat source cooking mode, under the driving of the driving member 141, the first transmission member 142 drives the second transmission member 143 to move relative to the third transmission member 144 to close to the cooking cavity 121, so as to shorten the distance between the heating member 130 and the cooking cavity 121, make the cooking cavity 121 close to the auxiliary heat source, and ensure the auxiliary heating effect of the heating member 130 on the cooking cavity 121.

[0089] When the cooking is completed, under the driving of the driving member 141, the first transmission member 142 drives the second transmission member 143 to move relative to the third transmission member 144 in a reverse direction to move away from the cooking cavity 121, so as to increase the distance between the heating member 130 and the pot body 120, and avoid contact and scratching between the pot body 120 and the heating member 130 during the process of taking and placing the pot body 120.

A part of the heating member 130 is located in the recess 147 through the through hole 146, and the part of the heating member 130 is connected to the movable body 145, realizing fixation of the heating member 130 on the second transmission member 143.

[0096]

[0097] ​​​The groove wall of the recess 147 is provided with a first matching part 148, and a second matching part 149 is arranged on the side of the movable body 145 away from the recess 147, that is, the first matching part 148 and the second matching part 149 are arranged on the inner and outer sides of the movable body 145 respectively, which is beneficial to improve the space utilization of the movable body 145 and reduce the occupied space of the driving device 140 in the appliance body 110.

[0098] Optionally, the third transmission member 144 is provided with a channel, the channel is in communication with the recess 147, and part of the heating member 130 extends into the channel.

[0099] In some embodiments, the first transmission member 142 comprises a worm, and the second matching part 149 comprises a turbine; and / or the first matching part 148 comprises a first thread, and the third transmission member 144 comprises a second thread.

[0100] In this embodiment, the first transmission member 142 comprises a worm, and the second matching part 149 comprises a turbine, that is, the first transmission member 142 and the second transmission member 143 realize power transmission through the transmission mode of the turbine and the worm, which is beneficial to ensure the smooth and reliable transmission process, and further ensure the smooth operation of the heating member 130.

[0101] The first matching part 148 comprises a first thread, and the third transmission member 144 comprises a second thread, that is, the second transmission member 143 and the third transmission member 144 are in threaded cooperation. Specifically, under the driving of the driving member 141, the worm drives the movable body 145 to rotate through cooperation with the turbine, and since the third transmission member 144 is fixed on the appliance body 110 and the third transmission member 144 is in threaded cooperation with the movable body 145, the movable body 145 can be lifted relative to the pot body 120 to approach or move away from the pot body 120.

[0102] As shown in FIGS. Figure 1 and Figure 2 In some embodiments, the appliance body 110 comprises a machine body 111 and a base 113, wherein the hot air assembly 150 is arranged in the machine body 111, the pot body 120 is arranged in the machine body 111 in a removable manner, the base 113 is arranged at the bottom of the machine body 111, the heating member 130 and the driving device 140 are arranged in the base 113, and the driving device 140 can drive at least part of the heating member 130 to move along the height direction of the machine body 111 to approach or move away from the pot body 120.

[0103] In this embodiment, the utensil body 110 is defined to include the body 111 and the base 113, specifically, the hot air assembly 150 is arranged on the body 111, and the heating element 130 and the driving device 140 are arranged on the base 113, since the base 113 is located at the bottom of the body 111, that is, the heating element 130 is located at the bottom of the pot body 120, and the driving device 140 can drive at least part of the heating element 130 to perform the lifting movement.

[0104] Specifically, when the air fryer 100 starts the multi-heat source cooking mode, under the driving of the driving device 140, at least part of the heating element 130 rises to be close to the cooking cavity 121, thereby shortening the distance between the heating element 130 and the cooking cavity 121, and making the cooking cavity 121 close to the auxiliary heat source, so as to ensure the auxiliary heating effect of the heating element 130 on the cooking cavity 121.

[0105] When the cooking is completed, under the driving of the driving device 140, at least part of the heating element 130 descends to be away from the cooking cavity 121, thereby increasing the distance between the heating element 130 and the pot body 120, and avoiding the contact and scratching of the pot body 120 and the heating element 130 during the process of taking and placing the pot body 120.

[0106] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , in some embodiments, optionally, the base 113 includes the seat body 114 and the heat insulation element 115, wherein the heat insulation element 115 is arranged on the seat body 114 and located between the seat body 114 and the pot body 120, the heat insulation element 115 and the seat body 114 enclose the heat insulation cavity 116, the driving device 140 is arranged in the heat insulation cavity 116, and the heating element 130 is arranged on the side of the heat insulation element 115 away from the heat insulation cavity 116.

[0107] In this embodiment, the base 113 is defined to include the seat body 114 and the heat insulation element 115, specifically, the heat insulation element 115 is arranged on the seat body 114, and the heat insulation element 115 is located between the seat body 114 and the pot body 120.

[0108] Since the driving device 140 is arranged in the heat insulation cavity 116, that is, the driving device 140 and the heating element 130 are isolated by the heat insulation element 115, thereby being able to reduce the heat generated by the heating element 130 and the heat in the cooking cavity 121 from being transferred to the driving device 140 on the premise of realizing the lifting movement of the heating element 130, which is conducive to ensuring the service life of the driving device 140, and further ensuring the smooth progress of the cooking process of the air fryer 100.

[0109] Optionally, the heat insulation member 115 is provided with a through hole in communication with the heat insulation cavity 116, and a portion of the heating member 130 passes through the through hole and is connected with the driving device 140.

[0110] As shown in FIGS. 1, 2 and 3, in some embodiments, the body 111 is provided with a receiving cavity 112, and the pot body 120 is removably arranged in the receiving cavity 112. The heat insulation member 115 is provided with a movable slot 117 away from one side of the seat body 114, and the movable slot 117 is in communication with the receiving cavity 112. The heating member 130 is movably arranged in the movable slot 117. Figure 1 、 Figure 3 and Figure 4 As shown in FIGS. 1, 2 and 3, in some embodiments, the body 111 is provided with a receiving cavity 112, and the pot body 120 is removably arranged in the receiving cavity 112. The heat insulation member 115 is provided with a movable slot 117 away from one side of the seat body 114, and the movable slot 117 is in communication with the receiving cavity 112. The heating member 130 is movably arranged in the movable slot 117.

[0111] In this embodiment, the body 111 is further provided with a receiving cavity 112, and specifically, the pot body 120 is removably arranged in the receiving cavity 112. The heat insulation member 115 is provided with a movable slot 117 away from one side of the seat body 114, and the movable slot 117 is in communication with the receiving cavity 112. Optionally, at least a portion of the heat insulation member 115 is recessed away from the cooking cavity 121 to form the movable slot 117. Since the heating member 130 is movably arranged in the movable slot 117, that is, under the driving of the driving device 140, the heating member 130 can perform lifting movement in the movable slot 117 to approach or move away from the cooking cavity 121.

[0112] By providing the movable slot 117, the problem that the overall height of the air fryer 100 is relatively high due to the arrangement of the movable heating member 130 can be solved while ensuring that the heating member 130 has a space for movement in the height direction, that is, the size of the overall machine in the height direction of the appliance body 110 can be reduced, thereby reducing the volume of the overall machine in the height direction and reducing the occupied space of the air fryer 100.

[0113] As shown in FIGS. 1, 2 and 3, in some embodiments, the body 111 is provided with a receiving cavity 112, and the pot body 120 is removably arranged in the receiving cavity 112. The heat insulation member 115 is provided with a movable slot 117 away from one side of the seat body 114, and the movable slot 117 is in communication with the receiving cavity 112. The heating member 130 is movably arranged in the movable slot 117. Figure 1 Optionally, along the height direction of the appliance body 110, the hot air assembly 150 and the heating member 130 are respectively located on opposite sides of the cooking cavity 121. Specifically, the hot air assembly 150 is located at the top of the cooking cavity 121, and the heating member 130 is located at the bottom of the cooking cavity 121. Alternatively, the hot air assembly 150 is located at the bottom of the cooking cavity 121, and the heating member 130 is located at the top of the cooking cavity 121. The specific arrangement can be made according to actual needs. Since the hot air assembly 150 and the heating member 130 are respectively located on the two sides of the cooking cavity 121 in the height direction, that is, the cooking cavity 121 is heated at different positions, the uniformity of the heating of the food materials in the cooking cavity 121 can be improved, and the cooking effect of the air fryer 100 can be improved. At the same time, since multiple heat sources heat the cooking cavity 121 at the same time, the cooking speed of the food materials can be accelerated, and the cooking time can be shortened.

[0114] In some embodiments, the heating element 130 is optionally movable between a first position and a second position, the first position being closer to the cooking cavity 121 than the second position; based on the heating element 130 being located at the first position, the heating element 130 is rotatable relative to the appliance body 110.

[0115] In this embodiment, when the heating element 130 is raised from the second position to the first position to allow the cooking cavity 121 to be close to the bottom heat source for auxiliary heating, the heating element 130 is rotatable at the first position, thereby significantly improving the situation that the heating element 130 heats unevenly on the bottom of the pot body 120 due to the distance between the heating element 130 and the pot body 120 being too close, improving the uniformity of heating of the food in the cooking cavity 121 while improving the cooking heat efficiency, thereby facilitating the improvement of the cooking effect.

[0116] Optionally, when the driving device 140 drives the heating element 130 to rise from the second position to the first position, the driving device 140 can also drive the heating element 130 to rotate at the first position, that is, one driving device 140 is used to realize the lifting and rotating movements of the heating element 130. Alternatively, the air fryer 100 further comprises a driving assembly, which drives the heating element 130 to rotate at the first position when the driving device 140 drives the heating element 130 to rise from the second position to the first position. The specific setting can be made according to the actual needs.

[0117] Optionally, when the heating element 130 is raised to the first position, since the third transmission member 144 is threadedly connected with the second transmission member 143, by controlling the forward and reverse rotation of the motor (driving member 141), the small-range rotating movement of the heating element 130 can be realized to improve the uniformity of heating of the cooking cavity 121.

[0118] Optionally, the thread connection can be replaced by thread and guide column connection, that is, the third transmission member 144 comprises a guide groove in the shape of a thread, and a guide column is arranged on the inner wall of the movable body 145, the guide column is inserted into the guide groove and is movable in the guide groove to allow the movable body 145 to rise or fall, so that when the heating element 130 is raised to the first position, the large-range rotating movement of the heating element 130 can be realized.

[0119] In a specific embodiment, it can be understood that in the traditional pull-out air frying, the lower heat source is arranged in a stationary state. In order to balance the production cost and manufacturing tolerance of parts and achieve a better user experience, the current heat pipe has an installation distance of about 10 mm from the bottom of the frying barrel, which is relatively large, resulting in that the auxiliary heating effect of the bottom heat pipe is not obvious.

[0120] Specifically, in the working process, the heat pipe (heating element 130) is fixedly installed on the rotating base (second transmission element 143) and is assembled with the power component (driving element 141 and first transmission element 142). After the frying barrel (pot body 120) is in place, the cooking program is started, and the program drives the power component to rotate and lift the heat pipe, and finally keeps it at a close distance from the bottom of the frying barrel, and continuously rotates under the control of the program. When the cooking is completed, the power component is controlled again through the program to slowly lower the heat pipe. Then the frying barrel can be pulled out. The cooking process lifts the heat pipe to improve the heat efficiency, and the rotating heat pipe improves the uniformity.
