[0038] Compared with the prior art, the above one or more technical solutions in the turntable 200 mechanism of the cooking appliance provided by the embodiment of the utility model have at least one of the following technical effects:

[0039] When in use, the turntable 200 is firmly mounted on the rotating frame 100 through the first clamping piece 310 and the second clamping piece 320. When the turntable 200 is driven by the rotating ring to rotate, the turntable 200 rotates smoothly without displacement and has a stable structure.

[0040] Further, one of the first clamping member 310 and the second clamping member 320 is a clamping slot, and the other is a clamping block.

[0043] In a specific embodiment, the support frame 120 is provided with three, and the three support frames 120 are evenly distributed in an annular manner on the rotating shaft 110, and the structure is stable. Of course, in other embodiments, the support frame 120 can also be provided with more than three, which can be determined according to actual production needs.

[0044] In another embodiment, the support frame 120 includes a support rod 121. One end of the support rod 121 is connected to the rotating shaft 110, and the support rod 121 is used to support the bottom of the turntable 200, so that the turntable 200 is stably mounted on the rotating frame 100. The other end of the support rod 121 extends a connecting rod 122 downward, and an end of the connecting rod 122 away from the support rod 121 extends a mounting rod 123 outward, and a gap is provided between the mounting rod 123 and the turntable 200. At least one rolling element 130 is rotatably provided at one end of the mounting rod 123 away from the connecting rod 122. The mounting rod 123 is located lower than the support rod 121, and provides space for the rolling element 130 to be mounted, so that the middle part of the turntable 200 is supported on the plurality of support rods 121 and the surrounding of the turntable 200 is in contact with the peripheral wall of the rolling element 130, thereby stably supporting the turntable 200, so that the cooking items can be stably placed on the turntable 200.

At the same time, the strength of the support rod 121 is enhanced by the first reinforcing rib 124, so that the structural strength of the support frame 120 is high and not easy to be deformed or damaged.

[0046] Furthermore, a second reinforcing rib 125 is provided in the middle of the lower end of the support rod 121 along its length direction, one end of the second reinforcing rib 125 extends to the connecting rod 122 and the mounting rod 123 in sequence and is connected to the lower ends of the connecting rod 122 and the mounting rod 123, the other end of the second reinforcing rib 125 is connected to two first reinforcing ribs 124 located on both sides thereof, thereby improving the strength of the second reinforcing rib 125, and at the same time, the strength of the support rod 121, the connecting rod 122 and the mounting rod 123 is enhanced by the second reinforcing rib 125, and combined with the first reinforcing rib 124, the structural strength of the support frame 120 is further improved, and the structure is firm and not easy to be damaged.

[0047] In another embodiment, the end of the support frame 120 away from the rotating shaft 110 is provided with a mounting shaft 126, and the rolling member 130 is a roller, and the wheel hole of the roller is rotatably provided with the mounting shaft 126. When the support frame 120 drives the turntable 200 to rotate, the roller rolls on the bottom of the cooking cavity 410, so that the support frame 120 moves smoothly and stably.

[0048] Furthermore, a limiting portion 127 is convexly provided at one end of the mounting shaft 126 away from the support frame 120. The limiting portion 127 is cylindrical, and the larger end of the limiting portion 127 is adjacent to the mounting shaft 126 and is larger than the wheel hole of the roller (rolling member 130). A slot 128 extending to the mounting shaft 126 is provided at the end of the limiting portion 127. The slot 128 divides the limiting portion 127 and the mounting shaft 126 into two halves. External force squeezes the two halves of the limiting portion 127 to elastically bend toward the slot 128 (inside) and become smaller, so that the wheel hole of the roller can pass through the limiting portion 127 and be installed on the mounting shaft 126, which is convenient for installing the roller. After the two halves of the limiting portion 127 are released from squeezing, the two halves of the limiting portion 127 elastically reset to the outside and become larger. The limiting portion 127 limits the roller to prevent the roller from falling off the mounting shaft 126, and the structure is reliable.

[0049] In another embodiment of the present invention, a cooking appliance (eg, a microwave oven, etc.) is provided, comprising a housing 400, a motor 420, and the above-mentioned turntable 200 mechanism of the cooking appliance.
