Description

Technical Field

[0001] The utility model relates to the technical field related to dishwashers, in particular to a buckled self-locking door cover. Background Art

[0002] Dishwashers are kitchen helpers in homes and businesses. They are devices used to automatically wash bowls, chopsticks, plates, dishes, knives, forks and other tableware to help people reduce the burden of housework.

[0003] The door opening and closing structure of the top-opening tabletop dishwashers on the market generally uses a combination of upper and lower magnets, relying on the principle of opposite magnets attracting each other to lock the door body. Opening the door body depends on people to overcome the magnetic force of the magnets to open the door cover. Since the magnetic force of each set of magnets cannot be completely consistent, and the N / S magnets are prone to magnetic force transfer after a long period of attraction, the door opening and closing feel is inconsistent, giving you a poor user experience. In addition, since the dishwasher is heated and washed inside, the internal cavity is subjected to excessive heat pressure. If the door opening force is set too small, the door body will easily be blown open by hot air; if the door opening force is set too large, it will make it difficult for users to open the door.

[0004] In summary, a snap-on self-locking door cover is needed that is easy to open and will not be automatically opened by hot air. Utility Model Content

[0005] The utility model aims to overcome the shortcomings in the prior art that if the door opening force of a dishwasher is set too low, the door body is easily opened by hot air; if the door opening force is set too high, it makes it difficult for the user to open the door. The utility model provides a snap-on self-locking door cover which is easy to open and will not be automatically opened by hot air.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A snap-on self-locking door cover comprises a lower body and an upper door cover, wherein a lock cavity is provided at the bottom of the upper door cover, a lock buckle through hole is provided on the bottom surface of the lock cavity, a lock buckle matching the lock buckle through hole is fixed at the upper end of the lower body, a lock tongue is installed in the lock cavity, one end of the lock tongue is engaged with the lock buckle, and the other end of the lock tongue is placed on the outer surface of the upper door cover.

[0008] When the upper door cover is placed on the upper end of the lower body, the lock catch passes through the lock catch through hole into the lock cavity and automatically engages with one end of the lock tongue, thereby locking the upper door cover. This has a simple structure, is easy to close, and the hot steam from washing cannot easily open the door, which is highly reliable. When the upper door cover needs to be opened, the user can move the other end of the lock tongue, thereby driving the entire lock tongue to move, separating one end of the lock tongue from the lock catch, thereby unlocking the upper door cover. This has a simple structure and is easy to open. The positioning and coordination of the lock block through hole and the lock catch guides the assembly between the upper door cover and the lower body, allowing the user to accurately place the upper door cover on the upper end of the lower body, thereby improving the convenience of closing the door.

[0009] Preferably, a bolt frame is fixed inside the lock cavity, and the bolt includes a rotating column, which is mounted on the bolt frame and rotatably connected thereto. A lock rod and a detent rod are provided on the rotating column, one end of the lock rod is fixed to the side wall of the rotating column, and the other end of the lock rod is engaged with a lock catch. One end of the detent rod is fixed to the side wall of the rotating column. The outer surface of the upper door cover is provided with a detent rod hole communicating with the lock cavity, and the other end of the detent rod is placed in the detent rod hole and movably connected thereto. When it is necessary to open the upper door cover, the user can detent the detent rod at the detent rod hole, thereby driving the lock rod on the rotating column to swing, so that the other end of the lock rod is separated from the lock catch, thereby unlocking the upper door cover. The structure is simple and the operation is convenient.

[0010] Preferably, the shift lever, the rotating column and the locking lever are designed as an integrated injection molding, which is convenient for processing.

[0011] Preferably, the upper door cover is provided with a handle groove on the outer side wall, the lever hole being located in the upper end wall of the handle groove. The lock rod and the lever are both L-shaped and are disposed on opposite sides of the rotating column. The other ends of the lock rod and the lever are both located below the rotating column. The other end of the lock rod is positioned between the rotating column and the lock catch through-hole. A buckle body 1 is fixed to the other end of the lock rod, and the buckle body 1 is located on the side of the lock rod near the lock catch through-hole. A buckle body 2 is fixed to the lock catch, matching the buckle body 1. The other end of the lock rod engages with the lock catch through the cooperation of the buckle bodies 1 and 2. The handle groove design facilitates user access to the upper door cover. When removing the upper door cover, since the other end of the lever is located in the upper end wall of the handle groove, the user can use a finger to push the other end of the lever upward, thereby causing the lock rod on the rotating column to swing downward, causing the buckle body 1 on the other end of the lock rod to flip downward and disengage from the buckle body 2 on the lock catch, thereby unlocking the upper door cover and allowing it to be easily lifted. The structure is simple and easy to operate.

[0012] Preferably, the locking rod and the first buckle body, and the locking buckle and the second buckle body are all integrated by injection molding, which is convenient for processing.

[0013] Preferably, a spring frame is fixed within the lock cavity, and a lever return spring is mounted on the spring frame. The lever return spring is located above the lever, with the top end of the lever return spring connected to the spring frame, and the bottom end of the lever return spring connected to the lever. The other end of the lever is pressed against the lever hole by the elastic force of the lever return spring, preventing the lock bolt from separating from the lock catch due to accidental rotation, thereby improving the stability of the locking connection. The lever return spring also automatically resets the entire lock bolt.

[0014] The beneficial effects of the utility model are: simple structure, convenient door opening and closing, the door will not be automatically opened by hot air, good reliability, convenience for users to take off the door cover, and improved locking stability. BRIEF DESCRIPTION OF THE DRAWINGS
