Specifically, the stopper elastic member 31 is an elastic member, which is a part of the door lock device 3, fixed to the side wall of the body 1, and is capable of providing a stable locking force in place. The arm 32 is a member fixed to the lower end of the side of the door panel 1, and is also a part of the door lock device 3, and the arm 32 rotates together with the door panel 1 to be switchable between a first position 4 and a second position 5, and the position of the arm 32 determines the state of the door panel 1, i.e., the open or closed state. When the door panel 1 is in the open state, the swivel arm 32 is in the first position 4, at which time the interior of the dishwasher is conveniently accessible and the user can place or remove dishes and utensils. When the user closes the door panel 1, the door panel 1 starts to rotate and the rotation arm 32 follows its movement, the rotation of the door panel 1 causing the rotation arm 32 to rotate from the first position 4 to the second position 5. With the door panel 1 in the closed position and the swivel arm 32 in the second position 5, the limit spring 31 acts as a lock that provides sufficient spring force to hold the door panel 1 closed and prevent accidental opening of the door panel 1 during dishwashing.

In commercial kitchens, dishwashers are subjected to a number of dish and ware washing tasks, the structure and working principle of which make them suitable for high-intensity use in commercial kitchens. When in use, the tableware and the utensils to be cleaned are well arranged so as to be quickly put into the machine body 1. The door panel 1 is opened, the rotating arm 32 is located at the first position 4, tableware and vessels are placed in the machine body 1, the door panel 1 is closed, the door panel 1 is ensured to be in a closed state, and the rotating arm 32 is located at the second position 5. The dishwasher is started to automatically complete the washing cycle. After the washing is completed, the door panel 1 is unlocked, and a user can open the door panel 1 and take out the washed tableware and ware for further processing and use.

In addition, when the door panel 1 of the dishwasher is in the closed state, the rotating arm 32 is located at the second position 5, and the limiting elastic member 31 is locked, the locking mechanism is designed to ensure that the door panel 1 is firmly locked in the closed state, and simultaneously can be easily unlocked when the door panel 1 needs to be opened, the limiting elastic member 31 may be a member with elasticity, such as a spring or other material capable of providing a certain elastic force, when the door panel 1 is closed, the limiting elastic member 31 is compressed or deformed and locks the door panel 1 in the closed position by the elastic force thereof, when the door panel 1 is opened, a user only needs to lightly dial the door panel 1, the elastic force of the limiting elastic member 31 can unlock and allow the door panel 1 to be transferred from the closed state to the open state, and the design can reduce the force required to be applied by the user when the door panel 1 is opened, thereby providing a more relaxed and convenient user experience. The cooperation of setting up spacing elastic component 31 and rocking arm 32 simultaneously ensures that door plant 1 provides better compactness when closing, and door plant 1 keeps firmly locking under the closed condition to avoid unexpected opening, improve dish washer's security. Through the synergism of the rotating arm 32 and the limiting elastic piece 31, a user can open only by lightly poking the door plate 1, and the design can reduce the force required to be applied when the user opens the door plate 1, so that a user experience which is easier and more convenient is provided.

In the design of the dish washer, when the door plate 1 is in an open state, the rotating arm 32 is located on a plane of the side edge of the side wall of the machine body 1, namely the first position 4, when the door plate 1 is closed, the rotating arm 32 can rotate to a plane of the bottom edge of the side wall of the machine body 1, namely the second position 5, at the moment, the locking state of the rotating arm 32 and the limiting elastic piece 31 can ensure that the door plate 1 is tightly closed, good sealing performance is provided, and the plane of the first position 4 and the plane of the second position 5 are perpendicular to each other.
