[0030] Please refer to Figures 1 to 4 The present application first provides a disc body telescopic structure, including equipment main body 10, door body 20 and disc body 30, one side of equipment main body 10 is provided with cooking cavity 11, door body 20 is hinged with equipment main body 10 and is used for opening or closing cooking cavity 11, disc body telescopic structure further includes linkage structure 40, linkage structure 40 includes guide rail 41, sliding frame 42 and first connecting rod 43, guide rail 41 is fixed to the inner wall of cooking cavity 11 and is towards the opening of cooking cavity 11, sliding frame 42 is slidably connected to guide rail 41, and first connecting rod 43 is hinged with sliding frame 42 and door body 20 at both ends respectively, disc body 30 is connected with sliding frame 42, so as to drive disc body 30 to extend or retract cooking cavity 11 through the opening and closing of door body 20.
[0031] In the present application, the disc body 30 is arranged on the sliding frame 42, and the door body 20 and the sliding frame 42 are connected through the first connecting rod 43, so that during the opening or closing process of the door body 20, the sliding frame 42 and the disc body 30 can be driven to extend or retract along the guide rail 41 through the first connecting rod 43, so that the user does not need to manually take out the disc body 30 from the cooking cavity 11, but only needs to directly take the food from the automatically extended disc body 30, which is more convenient for the user to use, and can reduce the possibility of scalding caused by the user accidentally touching the inner wall of the cooking cavity 11.
[0032] Specifically, the disc body 30 can be fixed with the sliding frame 42, or can be connected to the sliding frame 42 in other ways, as long as it can move together with the sliding frame 42, which is not limited further herein.
[0033] Preferably, the guide rail 41 is a multi-stage guide rail to increase the extension length of the sliding frame 42.
[0034] More preferably, the guide rail 41 is a three-stage guide rail.
[0035] Please refer to Figure 3 and Figure 4 In some embodiments, the linkage structure 40 further includes a gear 44, a rack 45, a rotating shaft 46, and a second connecting rod 47. The rack 45 is parallel to the guide rail 41 and is also fixed to the inner wall of the cooking cavity 11. The gear 44 is engaged with the rack 45. The rotating shaft 46 is rotationally connected with the sliding frame 42, and both ends of the rotating shaft 46 are fixed with the gear 44 and the second connecting rod 47, respectively. The second connecting rod 47 is also hingedly connected with the disc body 30.

Of course, in other embodiments, corresponding limiting members can also be provided to limit the movement trajectory of the disc body 30, as long as the disc body 30 can be further extended and retracted by the second connecting rod 47. The present application does not exemplify one by one.
[0041] Please refer to Figure 1 and Figure 2 As shown in the drawings, in some embodiments, the guide rail 41 is inclined downward near the opening end of the cooking cavity 11, so that the weight of the disc body 30 can assist it to extend outward, thereby reducing the pulling force required by the user during opening the door body 20, and facilitating the user operation.
[0042] Please refer to Figure 1 As shown in the drawings, in some embodiments, the disc body 30 is fixed with a U-shaped limiting plate 31, and the opening of the limiting plate 31 faces the opening of the cooking cavity 11. The limiting plate 31 is used to limit and position the position of the baking tray or steaming tray placed on the disc body 30, so as to further improve the convenience of the user to take and place the baking tray or steaming tray.
[0043] Please refer to Figure 5 As shown in the drawings, in some embodiments, the disc body extension structure further comprises an electric push rod 12 fixed to the equipment main body 10, and the extension end of the electric push rod 12 is hinged to the door body 20. By extending and retracting the electric push rod 12, the opening and closing of the door body 20 can be controlled and the disc body 30 can be extended or retracted, without the need for the user to manually open and close the door body 20, thereby further improving the convenience of the user to open and close the door body 20.
