The hinge motor 56 is a speed reducing motor, the speed reducing motor is fixed on the side wall of the hinge shell 51, and a driving main shaft of the speed reducing motor penetrates through the hinge shell 51 to enter the shell and is connected with the driving gear 55.

The electric driving hinge 5 is only arranged on one side of the hinge of the box door 6 and used as main power, the hinge on the other side is an unpowered hinge 561, and the electric driving hinge 5 and the unpowered hinge 561 are connected into a whole through a connecting plate 9.

The electric telescopic device 8 comprises a telescopic rack 81 fixed on the electric driving hinge 5 and a telescopic driving motor 82 fixed in the accommodating cavity 3, and a telescopic gear 83 meshed with the telescopic rack 81 is mounted on a main shaft of the telescopic driving motor 82.

The telescopic driving motor 82 is a speed reducing motor, and the telescopic rack 81 is fixed on the connecting plate 9.

The telescopic driving motor 82 is provided with a telescopic travel switch 84.

The accommodating cavity is also internally provided with a position locking device 7, and the position locking device 7 comprises a bolt 71 arranged on the connecting plate 9 and a lock body 72 arranged in the accommodating cavity;

the lock tongue 71 comprises a connecting seat 712 and a lock tongue plate 711, and the lock tongue plate 711 is provided with a third locking hole 713;

the lock body 72 comprises a lock support 721, a lock block 722 is installed in the lock support 721 in a swinging and hinged mode, the lock block 722 is arranged in a disc shape, a lock catch plate 723 and a buffer plate 724 are arranged on the outer circle of the lock block 722 and protrude out of the outline of the lock block, the lock catch plate 723 is buckled with a third lock hole 713 of the lock tongue 71 in a hanging mode or separated to achieve locking or unlocking, and a reset torsion spring 725 is arranged between the lock block 722 and the lock support 721;

The position locking devices 7 are provided with two sets and symmetrically arranged in the accommodating cavity.

The working principle is as follows: the oven door in the present case is opened and closed electrically, as shown in fig. 10, when a user needs to open the door, the hinge motor drives the driving gear to rotate, so as to drive the rack 54 to move, and the rotation of the motor is converted into the linear motion of the rack. When the rack moves, the pull arm 53 is inevitably driven to move back and forth, so that the trigger can be driven to rotate around a hinged point with the hinge shell by utilizing the movement of the pull arm, and the electric opening and closing of the oven door are realized. Consequently, compare with the manual switching chamber door of tradition, the oven door in this case can realize electronic opening and shutting, when the user needs the switching oven, need not manual operation, only need through operate corresponding electrical system can, when promoting operation science and technology and feel, the risk of hot gas scald when having avoided the oven to open.

As shown in fig. 8, when the oven door is completely opened, the oven door hiding function is activated, and the retractable driving motor 82 is rotated to engage with the retractable rack 81 through the retractable gear 83 installed on the main shaft thereof. Thereby driving the telescopic rack 81 to move, and when the telescopic rack 81 moves, the electric driving hinge 5 is driven to slide along the path of the guide rail 4 under the action of the guide rail 4, so as to drive the opened box door 6 to slide in the accommodating cavity 3. When the box door is finally wholly or partially hidden in the accommodating cavity, the front clearance or occupied space of the oven is reduced, and the operation of a user is facilitated. Thereby also preventing the user from being burned by the residual heat of the oven door.

In order to prevent the oven door from being opened or closed and prevent the oven hinge from moving backwards to cause failure in opening and closing the oven door, a position locking device is further arranged in the accommodating cavity and comprises a lock tongue 71 arranged on the connecting plate 7 and a lock body 72 arranged in the accommodating cavity; when the oven door slides out of the accommodating cavity, the lock tongue 71 moves towards the lock body to force the lock tongue piece to be inserted into the lock body, so that the lock catch plate 723 is buckled with the third lock hole 713 of the lock tongue 71 to realize locking, and the relative position of the oven hinge and the accommodating cavity is locked. After the lock is closed, the control system controls the solenoid valve to work, so that the valve core 727 of the solenoid valve 726 penetrates between the locking plate 723 and the buffer plate 724, and the rotation of the lock block 722 is locked. When the electric control system is not unlocked, even if external force pulls the door, the door hinge is locked and cannot move, so that the problem that the door cannot be closed or is difficult to close due to the fact that the oven hinge slides is avoided.

And when needs hide the chamber door, electric control system removes the locking of solenoid valve, and flexible driving motor reversal, through flexible rack drive chamber door after outwards moving to the initial point position, compare with traditional oven, the oven door in this case can realize electric switch, and electronic flexible hiding, when convenience of customers operates, promotes the security that operation science and technology felt and oven when using, so can extensively use widely.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
