On one hand, the installation structure of the door curtain is stable in the state that the door curtain shields the central window, and on the other hand, the door curtain can move more smoothly to enable the central window to be converted into an opening state from the shielded state.

The driving device is a driving motor and is arranged in a left-right mode, idler wheels are respectively installed on output shafts of the driving motors, outer side faces of the lower ends of the left vertical beam and the right vertical beam are respectively inwards recessed to form installation grooves used for installing the corresponding idler wheels, the installation grooves are respectively communicated with the corresponding installation grooves, and wheel faces of the idler wheels are respectively contacted with corresponding positions of the inner surface of the door curtain in a state that a central window of the door frame is shielded. When each driving motor rotates, each roller rotates synchronously, so that the door curtain is driven to move along each mounting groove, opening and closing of the central window are achieved, and automatic opening and closing of the door body are achieved.

Furthermore, the door curtain is made of a high-temperature-resistant and heat-insulating flexible material. Thereby can promote the thermal-insulated effect of heat preservation of door curtain, avoid the culinary art in-process external surface temperature rise too high of door, also can prolong the life of door curtain simultaneously, and then the life of the extension door body.

The technical solution adopted to further solve the fourth technical problem is as follows: an oven is characterized in that the oven is provided with the door body structure of the baking cooking device.

Compared with the prior art, the utility model has the advantages that: the door body comprises a door frame, a door curtain and a driving device, the door curtain can move back and forth along an installation groove formed in the door frame under the driving of the driving device to open or shield a central window of the door frame, so that the opening and closing of the door body are realized.

Firstly, under the state that the door curtain 32 shields the central window 310, the door curtain 32 is two layers arranged in front and at the back, so that the door body 3 can play a better role of heat preservation and heat insulation for the inner container 2 of the oven, secondly, the design of the inverted U-shaped mounting groove 34 can enable the door curtain 32 to move along each mounting groove 34 more stably, and further guarantee the reliability of the opening and closing control of the central window 310. The upper beam 311 of the door frame 31 has a hollow structure that vertically penetrates along the longitudinal direction thereof, and the top end of the door curtain 32 is accommodated in the upper beam 311 along the longitudinal direction of the top end in a state where the center window 310 of the door frame 31 is covered. On the one hand, the design through hollow out construction can reduce the weight of a body 3, reduce the manufacturing cost of a body 3, and on the other hand, the inner chamber of entablature 311 can play limiting displacement to the top of door curtain 32 to enable the installation of door curtain 32 in door frame 31 more firm.

Further, the lower beam 312 of the door frame 31 is formed with a stopper groove 37 penetrating in the longitudinal direction and communicating with each mounting groove 34, and the rear end of the door curtain 32 is fitted in the stopper groove 37 along the longitudinal direction. The consequence that the door curtain 32 can not be reset because the door curtain can slide out of the mounting groove 34 in the process of moving along each mounting groove 34 is avoided. Preferably, the rear end edge of the door curtain 32 is always exposed to the rear side of the door body 3 in the longitudinal direction thereof. On one hand, the door curtain 32 can be better prevented from sliding out of the mounting groove 34 in the moving process, and on the other hand, the door curtain 32 is convenient to disassemble and assemble. In this embodiment, the lower beam 312 of the door frame 31 is a hollow structure penetrating vertically along the length direction thereof, and the weight of the door body 3 can be reduced and the production cost of the door body 3 can be reduced by the design of the hollow structure.

In addition, the lower ends of the mounting grooves 34 are respectively communicated with the inner cavity of the lower cross member 312, and in a state where the central window 310 of the door frame 31 is shielded, the lower end of the front portion of the door curtain 32 extends vertically and the front surface of the lower end is attached to the front surface of the inner cavity of the lower cross member 312. On one hand, the mounting structure of the door curtain 32 is stable in the state that the door curtain 32 shields the central window 310, and on the other hand, the door curtain 32 can be moved more smoothly to rapidly switch the central window 310 from the shielded state to the open state.

In this embodiment, the driving devices 33 are two driving motors, and each driving motor has an output shaft on which a roller 36 is mounted, the outer side surfaces of the lower ends of the left vertical beam 313 and the right vertical beam 314 are recessed inward to form mounting grooves 35 for mounting the corresponding rollers 36, the mounting grooves 34 are communicated with the corresponding mounting grooves 35, and the wheel surfaces of the rollers 36 are in contact with the corresponding positions on the inner surface of the door curtain 32 when the central window 310 of the door frame 31 is shielded. When the driving motors rotate, the rollers 36 rotate synchronously, so as to drive the door curtain 32 to move along the mounting grooves 34, and further open and close the central window 310, namely, automatically open and close the door body 3.

In this embodiment, in the initial state, the door curtain 32 shields the central window 310 of the door frame 31 (i.e. the door body is closed), and when each driving motor rotates clockwise, each roller 36 rotates clockwise to drive the door curtain 32 to move backward along each mounting groove 34, and the central window 310 is opened (i.e. the door body 3 is opened). When the driving motors rotate counterclockwise, the rollers 36 rotate counterclockwise to drive the door curtain 32 to move forward along the mounting slots 34 until the central window 310 is covered again.
