BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic structural diagram of Embodiment 1 of the door-opening structure of the present utility model;

[0014] Figure 2 It is a schematic structural diagram of Embodiment 2 of the door-opening structure of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] In order to deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings. The embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

[0016] Embodiment 1

[0017] Please refer to the attached Figure 1 , the present utility model provides a door-opening structure for a steam oven, including a cabinet shell 1, an inner container 2 and a door 3. The inner container 2 is fixed inside the cabinet shell 1. The door 3 is connected to the cabinet shell and is used to open or close the front open end of the inner container. The lower part of the door is rotatably connected to the lower end of the cabinet shell through a door hinge member. A driving motor 4, a cam 5, a door-opening rod body 6 and a rod body guiding bracket 7 are arranged inside the cabinet shell 1. The rod body guiding bracket is arranged on the side wall of the inner container. The door-opening rod body 6 is slidably connected to the guiding bracket. The cam 5 is located behind the door-opening rod body and is used to drive the door-opening rod body to move forward. The driving motor 4 is used to drive the cam to rotate. The door-opening rod body is used to open the door. Specifically, the driving motor drives the cam to rotate. When the cam rotates, it gradually pushes the door-opening rod body upward, thereby opening the door and liberating the user's hands.

[0018] A motor bracket 8 is arranged behind the inner container 2. The driving motor is installed on the motor bracket. Usually, a fan and a heating tube are arranged on the back of the inner container of the micro steam oven. Arranging the driving motor and the motor bracket at this position can make full use of the idle space.

[0019] A force-bearing seat 9 is arranged at the rear end of the door-opening rod body 6. The force-bearing seat is installed on the door-opening rod body through screws. The force-bearing seat can indirectly increase the force-bearing area of the door-opening rod body, making it easier for the cam to contact and push the door-opening rod body.

[0020] The front end of the door-opening rod body 6 extends to be close to the inner side of the box door 3. When the cam pushes the door-opening rod body forward, the box door can be directly pushed open. Preferably, a spring member 10 is sleeved on the front end of the door-opening rod body 6. The spring member abuts against the box shell and the door-opening rod body respectively. After the cam pushes the door-opening rod body forward to the maximum, the cam will gradually disengage from the door-opening rod body. After the door-opening rod body loses the acting force of the cam, under the action of the spring member, it will move backward, so as to realize the "retraction" of the door-opening rod body.

[0021] Embodiment 2

[0022] The difference between Embodiment 2 and Embodiment 1 is that the door-opening rod body does not directly push open the lower box door. Specifically as follows: Refer to the attached Figure 2 , a door hook 11 for keeping the box door in a closed state is provided at the upper end of the box shell 1. The door hook is rotatably connected to the box shell. A rotatable transmission rod 12 is provided in front of the box shell where the door-opening rod body is located. One end of the transmission rod is connected to the door hook, and the front end of the door-opening rod body 6 abuts against the other end of the transmission rod 12. Specifically, the cam drives the door-opening rod body to move forward, and the door-opening rod body pushes the transmission rod forward. Under the principle of leverage, the end of the transmission rod connected to the door hook will swing backward, thereby driving the door hook to rotate and making the door hook disengage from the box door, and the box door opens under gravity.

[0023] A tension spring 13 is connected to the guiding bracket, and the tension spring is connected to the other end. After the cam pushes the door-opening rod body forward to the maximum, the cam will gradually disengage from the door-opening rod body. After the door-opening rod body loses the acting force of the cam, under the pulling force of the tension spring, the end of the transmission rod connected to the tension spring swings backward, and at the same time pushes the door-opening rod body back to its original position, while the end of the transmission rod body connected to the door hook swings forward and resets the door hook.

[0024] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. Any equivalent modifications or changes made by those of ordinary skill in the art according to the disclosure of the present invention shall be included in the protection scope recorded in the claims.
