When the dish washer is in a drying program, the fixed-angle automatic door opening mechanism operates, firstly, the door pushing mechanism 1 automatically pushes the door body 20 open, the door body 20 can rotate relative to the door frame 10 due to self weight and drives the hinge support 2 to rotate relative to the sliding block 3, meanwhile, the hinge support 2 drives the sliding block 3 to slide downwards, the sliding block 3 drives the supporting rod 42 to move downwards, and due to the fact that a gap is formed between the elastic piece 43 and the supporting block 41, the elastic piece 43 does not generate damping force at the moment, the door body 20 can be quickly opened, and the preset angle alpha is gradually opened. In this process, the slider 3 drives the support rod 42 and the elastic member 43 to move downwards, and when the door body 20 is opened a certain angle (less than a preset angle α), the bottom end of the elastic member 43 is attached to the support block 41, the numerical value of the gap is zero at this moment, and the elastic member 43 is about to be compressed at this moment, when the door body 20 is opened the preset angle α, the elastic member 43 is compressed and has a certain damping force, the damping force can balance the dead weight of the door body 20, so as to prevent the door body 20 from continuing to rotate, and the opening angle of the door body 20 is constant. With the above configuration, the constant angle is formed by the self-weight opening of the door 20, and therefore, the angle is sufficiently large, and the drying effect can be improved and the power consumption can be reduced.

When a user needs to completely open the door body 20 to take out the cleaned tableware, the user can apply force to the door body 20 to enable the door body 20 to continue rotating, the supporting rod 42 continues to be driven by the sliding block 3 to move downwards at the moment, the elastic piece 43 is compressed, and the force is applied by the user, so that the damping force generated by the elastic piece 43 can be overcome, and the door body 20 is opened.

The rest of the structure of this embodiment is the same as that of the first embodiment, and is not described again.
