[0042] Please refer to Figures 1 to 3 , a cooking appliance in one embodiment includes a cooking structure 10, the cooking structure 10 includes a handle 300, a lid 200, a support frame 100 and a heating assembly 400. The heating assembly 400 is provided with a heating cavity 412. The support frame 100 is detachably installed on the side wall of the heating cavity 412. The lid 200 is provided with a receiving cavity 210 and a first insertion hole 222 communicating with the receiving cavity 210. The lid 200 is detachably covered on the support frame 100 through the receiving cavity 210. The handle 300 is rotatably inserted into the first insertion hole 222. The heating assembly 400 further includes a heating element 430. The steam generated by the heating element 430 heats the food on the support frame 100. Specifically, the cooking appliance further includes a heating box. When in use, the food is placed in the heating box, and then the heating box is placed on the support frame 100 for heating.

[0043] The handle 300 has a first state and a second state. Please refer to Figure 3 , when the handle 300 is in the first state, the handle 300 rotates to be locked and cooperated with the support frame 100; when the handle 300 is in the second state, the handle 300 rotates to be separated from the support frame 100. Thus, when the food is heated, rotate the handle 300 to make the handle 300 in the first state. At this time, the handle 300 and the support frame 100 are locked and cooperated. Lift the handle 300 to lift the lid 200 and the support frame 100 together to remove the support frame 100 from the heating assembly 400, thereby avoiding certain burns caused by the user directly taking the support frame 100 by hand; when the support frame 100 is removed, the handle 300 can be rotated to make the handle 300 in the second state. At this time, the handle 300 rotates to be separated from the support frame 100, and then the lid 200 and the support frame 100 can be separated to remove the food on the support frame 100.

[0044] In the foregoing embodiment, the handle 300 rotates to be locked and cooperated with the support frame 100 means that the handle 300 is limited and cooperated with the support frame 100 in the direction opposite to the gravity of the support frame 100, so that the handle 300 can lift the support frame 100. It does not mean that the handle 300 and the support frame 100 must be completely fixed. In this embodiment, when the handle 300 is rotated in the opposite direction, the handle 300 and the support frame 100 can be separated.

[0045] Please refer to Figure 4 , in one of the embodiments, one end of the handle 300 is limited and cooperated with the lid 200 to prevent the handle 300 from falling off along the first insertion hole 222; specifically, one end of the handle 300 is provided with a rotating portion 310, and the cross-sectional area of the rotating portion 310 is larger than the cross-sectional area of the first insertion hole 222 so that the rotating portion 310 is limited and cooperated with the side wall of the lid 200. Optionally, the rotating portion 310 is in a long strip shape, which is convenient for the user to hold.

[0046] Further, in order to prevent the rotating part 310 from rotating excessively during rotation, making it difficult to lock and fit the handle 300 with the support frame 100 or the heating component 400, please refer to Figure 5 , in one embodiment, the cover body 200 is provided with a first limiting protrusion 224 and a second limiting protrusion 226 arranged at intervals. The rotating part 310 is limited and cooperated with the first limiting protrusion 224 and the second limiting protrusion 226 so that the rotating part 310 can rotate between the first limiting protrusion 224 and the second limiting protrusion 226.

[0047] Optionally, please refer to Figure 5 , the cover body 200 further includes a third mounting post 220. The third mounting post 220 is provided with a first insertion hole 222. The first limiting protrusion 224 and the second limiting protrusion 226 are arranged at the opening edge of the first insertion hole 222 in the third mounting post 220.

[0048] Further, please refer to Figure 4 and Figure 6 , the support frame 100 is provided with a second insertion hole 112. The other end of the handle 300 passes through the first insertion hole 222 and is rotatably inserted into the second insertion hole 112. At this time, part of the heating component 400 extends into the second insertion hole 112.

[0049] Please refer to Figure 4 , the handle 300 further has a third state. When the handle 300 is in the third state, the other end of the handle 300 is locked and cooperated with the heating component 400 so that the cover body 200 is locked and cooperated with the heating component 400 through the handle 300; at this time, by rotating the handle 300, the handle 300 is locked with the heating component 400. Since the handle 300 is limited and cooperated with the cover body 200, therefore, the cover body 200 and the heating component 400 are fixed through the handle 300. In this way, the assembly of the cooking appliance is completed.

[0050] After heating is completed, rotate the handle 300 to make the handle 300 in the first state. The handle 300 is separated from the heating component 400 and the handle 300 is locked and cooperated with the support frame 100. In this way, not only can the support frame 100 be separated from the heating component 400, but also the support frame 100 and the cover body 200 can continue to be in a locked state. Lifting the handle 300 can lift the cover body 200 and the support frame 100 together to remove the support frame 100 from the heating component 400, thereby avoiding certain burns caused by the user directly taking the support frame 100 by hand.

[0051] Please refer to Figure 4 and Figure 7, in one embodiment, the heating component 400 is provided with a third insertion hole 422. The other end of the handle 300 extends into the second insertion hole 112 and the third insertion hole 422 at the same time. The other end of the handle 300 is provided with a first locking portion 340 and a second locking portion 350 that are spaced apart along the length direction of the handle 300. The inner wall of the second insertion hole 112 is provided with a third locking portion 1122 for locking and cooperating with the first locking portion 340. The inner wall of the third insertion hole 422 is provided with a fourth locking portion 4222 for locking and cooperating with the second locking portion 350. The third locking portion 1122 and the fourth locking portion 4222 are arranged in a staggered manner. Among them, the purpose of the staggered arrangement of the third locking portion 1122 and the fourth locking portion 4222 is that when the handle 300 rotates, the locking can be switched between the third locking portion 1122 and the fourth locking portion 4222.

[0052] Specifically, please refer to Figure 4 , when the handle 300 is in the third state, the second locking portion 350 is locked and cooperated with the fourth locking portion 4222, and the first locking portion 340 is separated from the third locking portion 1122. At this time, the cover body 200 can be fixed to the heating component 400 through the handle 300, thereby realizing the assembly of the cooking appliance.

[0053] Please refer to Figure 3 , when the handle 300 is in the first state, the second locking portion 350 is separated from the fourth locking portion 4222, and the first locking portion 340 is locked and cooperated with the third locking portion 1122. At this time, either the support frame 100 is separated from the heating component 400, or the support frame 100 and the cover body 200 can continue to maintain the locked state.

[0054] Optionally, the first locking portion 340 is a first hook, the second locking portion 350 is a second hook, the third locking portion 1122 is a third hook, and the fourth locking portion 4222 is a fourth hook.

[0055] Please refer to 3 and Figure 4 , in order to facilitate the installation between the support frame 100 and the heating, in one embodiment, the support frame 100 includes a first mounting post 110. The first mounting post 110 is provided with a second insertion hole 112. The heating component 400 is provided with a heating cavity 412. The heating component 400 further includes a second mounting post 420. One end of the second mounting post 420 is fixedly arranged on the inner wall of the heating cavity 412. The second mounting post 420 is provided with a third insertion hole 422. The inner wall of the heating cavity 412 is provided with a connecting portion 4122 for detachably connecting with the support frame 100.

[0056] During assembly, first detachably connect the support frame 100 and the connecting portion 4122. Among them, there are various ways of detachable connection, such as snap connection or lap joint; please refer to Figure 4 and Figure 7, in this embodiment, the connecting portion 4122 is a lapping step formed at the opening of the heating cavity 412. During installation, the support frame 100 can be lapped on the lapping step to support the support frame 100.

[0057] When the support frame 100 is detachably connected to the connecting portion 4122, the other end of the second mounting post 420 extends into the second insertion hole 112. In order to enable the handle 300 to switch and lock between the support frame 100 and the heating assembly 400 when lifted and inserted into the third insertion hole 422, please refer to Figure 4 , in this embodiment, the height of the third locking portion 1122 relative to the bottom wall of the heating cavity 412 is higher than the height of the end of the other end of the second mounting post 420 relative to the bottom wall of the heating cavity 412. At this time, the first locking portion 340 and the second locking portion 350 are spaced apart along the length direction of the handle 300 (such as Figure 8 the double-arrow direction in), the first locking portion 340 can correspond to the third locking portion 1122 in height, and the second locking portion 350 can exactly correspond to the fourth locking portion 4222 in height.

[0058] Optionally, please refer to Figure 4 , the portion of the second mounting post 420 located at the insertion port of the third insertion hole 422 is bent toward the insertion direction of the third insertion hole 422 to form a fourth hook, and the second hook corresponding to the fourth hook has a bending direction exactly opposite to that of the fourth hook. Similarly, the portion of the first mounting post 110 located at the insertion port of the second insertion hole 112 is bent toward the insertion direction of the second insertion hole 112 to form a third hook, and the first hook corresponding to the third hook has a bending direction exactly opposite to that of the third hook.

[0059] When food is placed on the support frame 100, it will exert pressure on the support frame 100 under the action of gravity. In order to prevent the support frame 100 from falling off into the heating cavity 412 under the action of pressure, please refer to Figure 8 , in one embodiment, a support portion 1124 is further provided on the inner wall of the second insertion hole 112. The support portion 1124 and the third locking portion 1122 are spaced apart along the circumferential direction of the second insertion hole 112, and an insertion gap 1126 is formed between the support portion 1124 and the third locking portion 1122. The first locking portion 340 can rotate below the support portion 1124 and the third locking portion 1122 by passing through the insertion gap 1126.

[0060] Optionally, the support portion 1124 can be a support protrusion.

[0061] Please refer to Figure 4, when the handle 300 is in the third state, the second locking portion 350 and the fourth locking portion 4222 are in locking cooperation. The first locking portion 340 rotates to directly below the support portion 1124 and at least part of the orthographic projection of the first locking portion 340 falls on the support portion 1124. In this way, there is a certain limiting cooperation between the support portion 1124 and the first locking portion 340, and the first locking portion 340 can play a role in supporting the support frame 100.

[0062] In one embodiment, please refer to Figure 4 and Figure 8 , the handle 300 is provided with a channel 370 penetrating the side wall of the handle 300. When the second locking portion 350 and the fourth locking portion 4222 are in locking cooperation, the channel 370 communicates with the third insertion hole 422. The heating assembly 400 further includes a heating element 430, a heating housing 410 and a mounting housing 440. The heating housing 410 is provided with a heating cavity 412, and the mounting housing 440 is provided with a mounting cavity 442. The heating housing 410 is disposed in the mounting cavity 442, the heating element 430 is disposed in the mounting cavity 442, the heating housing 410 is provided with a drain port 414, the third insertion hole 422 communicates with the drain port 414, the heating end of the heating element 430 is located below the drain port 414 and the drain port 414 faces the heating end of the heating element 430. The handle 300 is provided with a channel 370 penetrating the side wall of the handle 300. When the second locking portion 350 and the fourth locking portion 4222 are in locking cooperation, the channel 370 communicates with the third insertion hole 422. In this way, water can be directly poured into the third insertion hole 422 along the channel 370 and directly conveyed to the heating end of the heating element 430 through the drain port 414, improving the heating efficiency.

[0063] Further, please refer to Figure 1 , the cooking appliance further includes a switch member 500. The switch member 500 is disposed at the water injection port of the channel 370. When water needs to be injected into the channel 370, the switch member 500 is opened; when the water injection is completed, the switch member 500 needs to be closed. Optionally, the switch member 500 can be a snap-fastening valve. Pressing the switch member 500 opens the switch member 500, and pressing the switch member 500 again closes it. The switch member 500 can be a valve in the prior art as long as it can control the opening and closing of the water injection port, and will not be elaborated here one by one. In addition, a first exhaust gap 510 is formed between the switch member 500 and the side wall of the water injection port, and steam generated when heating food can be discharged along the first exhaust gap 510.

[0064] Please refer to Figure 4 and Figure 8, in one embodiment, the handle 300 includes a first section 320 and a second section 330 connected to the first section 320. A channel 370 runs through the first section 320 and the second section 330. The first section 320 is inserted into the first insertion hole 222, and at least a part of the second section 330 is inserted into the third insertion hole 422. The cross-sectional area of the part of the channel 370 located in the second section 330 gradually decreases along the flow direction of the channel 370. In this way, the part of the channel 370 located in the second section 330 can play a guiding role to facilitate the water to be guided to the heating end of the heating element 430.

[0065] During the cooking process, a large amount of high-temperature steam will be generated. In order to prevent the high-temperature steam from discharging along the gap between the handle 300 and the first insertion hole 222 and scalding the user, please refer to Figure 4 , in one embodiment, the cooking structure 10 further includes a seal 600. The seal 600 is disposed between the inner wall of the first insertion hole 222 and the handle 300. In this way, the steam generated during the heating process cannot discharge along the gap between the inner wall of the first insertion hole 222 and the handle 300.

[0066] Furthermore, please refer to Figure 4 , the cover 200 further includes a blocking protrusion 230. The blocking protrusion 230 is fixedly provided on the inner wall of the first insertion hole 222. The blocking protrusion 230 is disposed in the middle of the first insertion hole 222. The seal 600 is disposed between the blocking protrusion 230 and the handle 300. When the cover 200 covers the support frame 100, a second exhaust gap 228 is formed by the spaced arrangement between the third mounting post 220 and the first mounting post 110. In this way, the steam between the support frame 100 and the cover 200 can be discharged along the second exhaust gap 228 into the second insertion hole 112, and then discharged along the gap between the handle 300 and the third insertion hole 422 into the third insertion hole 422 and then discharged along the first exhaust gap 510.

[0067] In order to fix the seal 600, on the basis of the foregoing implementation, please refer to Figure 4 and Figure 8 , in this embodiment, a third limiting protrusion 360 is formed on the outer wall of the handle 300.
