Problems solved by technology
The button 1 and the release lever 2 are two parts. When the button 1 is pressed, the push rod 3 is in contact with the release lever 2. Due to the pressure of the pressure spring 4, the release lever 2 will also press the button 1 to make the button bounce back. Sometimes there is interference between button 1 and the control panel, which will cause poor rebound of button 1

Embodiment Construction
[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0024] The operating principle of the microwave oven of the present invention is the same as the prior art, and the prior art can be referred to, so it will not be described again. The difference between the present invention and the prior art is that the door switch structure of the microwave oven is different, and is described in detail below:
[0025] Such as Figure 3-7 As shown, the door switch of the microwave oven of the present invention includes a button 11, a push rod 13, a release rod 15 and a spring 14. The button 11, the push rod 13 and the release rod 15 are integrally formed, and the release rod 15 is connected to the control panel through the upper rotating shaft 17 18 connections, the torsion spring 14 that controls the switch of the button 11 is sleeved on the rotating shaft 17. One end of the torsion strut at both ends of the...

The invention discloses a door switch of a microwave oven, comprising a button, a pushing rod, a releasing rod and a spring; the button, the pushing rod and the releasing rod are integrated; the releasing rod is connected with a control panel by a rotating shaft above the releasing rod; and a torque spring for controlling a button switch is sleeved on the rotating shaft. As the button, the pushing rod and the releasing rod are integrated, the door switch can thoroughly and effectively prevent poor rebound of the button; and when the button is pressed, the button and the control panel are not contacted, and the button is not interfered in advance and does not cause poor rebound. After the button is pressed and the door is opened, the door is rebounded by the torque spring linked between the releasing rod and the control panel. In the whole process, the button does not interfere with the control panel, thus solving the problem that the rebound of the button is poor.
Description
technical field [0001] The invention relates to a microwave oven, in particular to a door switch for a microwave oven which solves the problem of poor key rebound. Background technique [0002] A microwave oven is a device that uses electric current to generate microwaves and irradiates the microwaves in food to heat the food. It can heat the surface and inside of the food at the same time, and can quickly cook a variety of foods. [0003] In order for the microwave oven to cook food in various cooking methods, the output power needs to be adjusted according to the user's requirements. As an output power adjustment device, a knob is usually used. [0004] Such as figure 1 As shown, the microwave oven 1 of the conventional art has a cuboid shape, and its top surface and the appearance of the left and right sides are formed by the casing 10 . [0005] A barbecue cavity 20 is formed inside the shell 10, which occupies most of the space and is used for accommodating food. Th...
