Of course, the driving device 500 of this embodiment is not limited to a device outputting linear reciprocating motion, but may also be a device outputting torque, for example, the output shaft of the motor directly drives the transmission arm 400 to rotate, but this structure needs to fixedly connect the output shaft of the motor with the transmission arm 400, which increases the assembly difficulty.

The elastic pushing device 600 of the present embodiment includes a rod 610 and a third elastic member 620, wherein the rod 610 has a first end 611 and a second end 612 opposite to each other, and the third elastic member 620 is sleeved on the rod 610; accordingly, the case 200 of the present embodiment is provided with a first mounting portion 220 and a second mounting portion 230 which are oppositely arranged, the first mounting portion 220 and the second mounting portion 230 can be both structures having plate-shaped members as shown in the figure, and the first mounting portion 220 of the present embodiment is provided with a first mounting hole, and the second mounting portion 230 is provided with a second mounting hole.

The first end 611 of the rod body 610 of this embodiment is inserted into the first mounting hole, and when the door body 100 is closed, the first end 611 abuts against the door body 100; the second end 612 is inserted into the second mounting hole, and the rod body 610 of this embodiment can slide back and forth in one direction (e.g., horizontal direction in the figure) by inserting the first end 611 into the first mounting hole and inserting the second end 612 into the second mounting hole.

In this embodiment, one end of the third elastic element 620 is in limit fit with the rod 610 or the first mounting portion 220, and the other end is in limit fit with the second mounting portion 230. Preferably, between the first end 611 and the second end 612 of the rod 610 of the embodiment, the rod 610 is provided with a limiting portion 613; one end of the third elastic element 620 is in limit fit with the limit portion 613, which not only facilitates the limit of the third elastic element 620, but also facilitates the installation of the whole elastic pushing device 600.

Through the above structure, when the door body 100 is closed, the door body 100 pushes the rod body 610, so that the third elastic member 620 can be compressed under the limit of the limit portion 613 and the second mounting portion 230 to generate elastic potential energy, and when the door body 100 is opened, the elastic potential energy of the third elastic member 620 is released to further push the door body 100 to be opened.

As a preferred embodiment of the present embodiment, the second mounting portion 230 of the present embodiment is mounted with a switch structure 900, the switch structure 900 may be a micro switch, or may be another inductive switch, such as a reed switch, and the switch structure 900 is connected to an operating circuit (not shown) of the cooking apparatus and is used for opening and closing the operating circuit, and the operating circuit is used for opening and closing a heating device (not shown) and a driving device 500 of the cooking apparatus.

When the door body 100 of the present embodiment is closed, the second end 612 opens the switch structure 900, the working circuit is switched on, and the heating device of the cooking apparatus can be turned on through the working circuit to perform heating operation; when the door body 100 of this embodiment is opened, the switch structure 900 is closed, and the working circuit is closed, so that the cooking device is prevented from being still in a heating state when the body is opened, and the device performance is prevented from being influenced and potential safety hazards are prevented from being generated.

The following describes a specific operation of the door opening and closing mechanism of the present embodiment:

referring to fig. 1 and 2, at this time, the door body 100 of this embodiment is in a closed state, the door hook 300 is in a limit fit with the limit seat 210, the door body 100 cannot be opened, the push rod of the driving device 500 is in a contracted state and abuts against the first transmission end 410 of the transmission arm 400, the third elastic member 620 of the elastic pushing device 600 is compressed under the action of the door body 100, the first end 611 of the rod body 610 abuts against the door body 100, the micro switch is opened at the second end 612, the micro switch feeds back a signal to the working circuit, and because the key on the control panel of the cooking device is not started, the working circuit does not supply power to the push rod motor at this time, but the heating device can be opened to perform cooking work.

Referring to fig. 3 and 4, when the door needs to be opened, the power supply of the operating circuit and the driving device 500 is switched on through the button on the control panel of the cooking apparatus, the push rod of the driving device 500 pushes the driving arm 400 to rotate, and the second driving end 420 of the driving arm 400 pushes the door hook 300 to rotate, so that the door hook 300 is disengaged from the limit fit with the limit seat 210.

Further, as shown in fig. 5 and 6, since the limit fit between the door hook 300 and the limit seat 210 is released, the door body 100 has no limitation on the rod body 610 of the elastic pushing device 600, the elastic force of the third elastic member 620 compressed by the door body 100 is released, and then the rod body 610 is driven to push the door body 100 to open, so as to complete the door opening operation, and the door body 100 is opened to the state shown in the figure. At this time, the second end 612 of the rod 610 leaves the micro switch, the micro switch is turned off to work, meanwhile, the micro switch feeds back information to the working circuit, the working circuit cuts off the power supply of the heating device, and the cooking device is in a shutdown state and cannot be started to work, so that the safety is ensured.

And in the process that the door body 100 is opened, the first elastic member 700 and the second elastic member 800 of this embodiment are all stretched, after the door body 100 is opened, the first elastic member 700 drives the door hook 300 to reset to the first state, the second elastic member 800 drives the transmission arm 400 to restore to the state when the door body 100 is closed, and then when the door body 100 is rotated to the closed state by opening, the hook portion 310 of the door hook 300 of this embodiment can slide into the limit position along the guide surface 213 of the limit seat 210, and then the closing locking of the door body 100 is completed.

In summary, according to the door opening mechanism provided in this embodiment, the door opening button may be disposed on the cooking device, and the door opening button operates the driving device 500, so that the door body 100 is opened under the combined action of the driving device 500, the transmission arm 400, the door hook 300, and the elastic pushing device 600, thereby realizing the automation of door opening; not only is convenient for the door opening operation, but also does not need to be provided with door opening structures such as a handle and the like, thereby reducing the occupation of the kitchen space.
