Problems solved by technology

In these special working scenarios, due to the problem that the locking force of the dishwasher door lock is not strong, if the user misoperates, it is easy to pull the dishwasher door; Out of curiosity or naughtiness, open the dishwasher door, causing burns and other safety issues
[0004] At present, some manufacturers are trying to solve the above problems, but the current technical solutions cannot perform operations such as opening the door and putting it in during the working process of the dishwasher. If the door is forced to open in the locked state, the parts will be damaged and the door lock will become invalid.
And this solution makes the force value required when opening and closing the door will be increased when the dishwasher is not working, which will have a negative impact on user experience
That is, the current technical solutions cannot balance security and convenience
Second, it is also necessary to consider the situation of sudden power failure in the locked state: after a sudden power failure, the door lock will remain locked and will not be automatically released. In actual use, it is necessary to wait for the power to be restored. Sliding the door will cause damage to the door lock and other parts
Third, the lock status signal feedback is not considered

Embodiment 1

[0039] Such as figure 1 with 2 As shown, a safety door lock, a latch arm 11 is arranged inside the door lock, and the door lock also includes a limit block 16 and a driving assembly 12 . The limiting block 16 is located outside the latch arm 11 , and the driving assembly 12 is used to drive the limiting block 16 . When the dishwasher is in a state with general safety requirements, the dishwasher door can be opened at any time. Such as figure 1 As shown, after the dishwasher door is closed, the safety door lock is in an unlocked state, the limit block 16 keeps a distance from the latch arm 11, and the latch arm 11 moves freely. At this time, it is only necessary to overcome the latch arm 11 and the latch to open the dishwasher door Resistance among the first 10, customer experience is good. When the dishwasher is in a state with high safety requirements (such as high-temperature washing), such as figure 2 As shown, after the dishwasher door is closed, the safety door lock i...

Embodiment 2

[0050] In the first embodiment, a safety door lock in which the latch arm is divided into two latch arms is exemplified, but the situation that the latch arm is a single latch arm is also relatively common. Figure 5 If the dishwasher door is not closed, image 3 with Figure 4 After the dishwasher door is closed, the safety door lock is unlocked and the safety door lock is locked. exist Figure 4 Among them, one end of the latch arm 21 is connected to the wall of the safety door lock by an elastic member, and the other end is hinged in the safety door lock. The latch head 20 is hooked by the latch arm 21, and the dishwasher door is in a closed state. The limit block 26 is against the latch arm 21, and the safety door lock is in a locked state.

Embodiment 3

[0052] Such as Image 6 with 7 As shown, on the basis of the first embodiment, the limiting blocks are set as the first limiting block 361 and the second limiting block 362 . One end of the second limiting block 362 is hinged, or fixedly connected, or pressed against one side of the latch arm 31 by an elastic component. The first limiting block 361 is located outside the other end of the second limiting block 362 , and may also be located on the upper left or upper side of the other end of the second limiting block 362 . When the safety door lock is in the unlocked state, the first limit block 361 keeps a distance from the second limit block 362, and the latch arm 31 moves freely; when the door lock is in the locked state, the first limit block 361 Close to or against the second limiting block 362 , the latch arm is restricted from moving freely by the second limiting block 362 .

Abstract

The invention discloses a safety door lock and a dish washing machine with the safety door lock. A latch arm, a limiting block and a driving assembly are arranged in the door lock. The limiting block is located on the outer side of the latch arm, and the driving assembly is used for driving the limiting block. When the door lock is in a non-locking state, a distance is kept between the limiting block and the latch arm, and the latch arm freely moves; and when the door lock is in a locked state, the limiting block is close to or abuts against the latch arm to limit free movement of the latch arm. The safety door lock can ensure that household appliances (such as a dish-washing machine) are in a safe state that the door is not easy to open when necessary, and meanwhile, ensures that the good door opening and closing experience of customers is not influenced. If the safety door lock is in a locked state, even if the door needs to be opened under special conditions (such as power failure in emergency), the door of the dish-washing machine can be forcibly opened without damaging the door lock. In addition, the safety door lock and the dish washing machine with the safety door lock can feed back the locking state of the safety door lock.

Description

technical field [0001] The invention belongs to the technical field of dishwashers, in particular to a safety door lock and a dishwasher with a safety door lock. Background technique [0002] During the working process of the dishwasher, the bolt and the door lock are generally used to close the door. The bolt and the door lock are respectively installed on the door and the main body of the dishwasher. The door lock has a latch arm, and an elastic mechanism (such as torsion spring, compression spring, extension spring) directly or indirectly acting on the latch arm. During the door closing process, the bolt head collides with the latch arm, pushing it away from the current position, during which the elastic force is overcome, and finally the door is closed; the door opening process is similar to the door closing process. Since the bolt and the door lock cooperate with each other, a certain force needs to be applied to the door when the dishwasher opens and closes the door....
