Example 1
As shown in fig. 1, the present embodiment provides a door lock system for a home appliance, which may be a washing machine, a dishwasher, a washing and drying machine, a dryer, etc. The embodiment specifically describes the household appliance door lock system by taking a dishwasher as an example. One working cycle of the dishwasher according to the embodiment includes a washing process, a rinsing process, and a drying process.
The door lock system of the household appliance comprises a door switch 2 for unlocking and locking a body 1 of the household appliance and a door body 4 of the household appliance; the blocking component 3 is electrically connected to a controller of the household appliance and is rotationally connected to the body 1, and in a first preset working process of the household appliance, the blocking component 3 can rotate to one side of the door switch 2 to limit the door switch 2 to rotate to the side where the blocking component 3 is located, and the door switch 2 is locked to enable the body 1 and the door body 4 to keep a locking state.
In the embodiment, the blocking component 3 controlled by the controller to act is arranged to realize automatic locking and unlocking of the door switch 2; the double locking of the door body 4 is achieved by the blocking assembly 3 and the door switch 2. The first preset operation in this embodiment refers to a drying process of the dishwasher. In the stoving in-process of dish washer, lock door switch 2 through blocking subassembly 3 for when external force acts on door switch 2, door switch 2 is because by the locking and unable action, will body 1 with door body 4 keeps locking state, promptly in the stoving in-process of dish washer, the user will be unable to open door body 4 through the mode of conventional unblock door switch 2, has solved the user and has opened the easy problem of being scalded of door body 4 because of the maloperation in the stoving in-process of dish washer.
As shown in fig. 2, the door body 4 is provided with a slot 41, and the door switch 2 includes a door switch body 21 rotatably connected to the body 1, and a door tongue 22 provided at one end of the door switch body 21 and capable of being inserted into or removed from the slot 41. Specifically, the two ends of the door switch 2 are respectively provided with a first arc-shaped groove 24 and a second arc-shaped groove 25, and the body 1 is provided with a first limit post 11 inserted into the first arc-shaped groove 24 and a second limit post 12 inserted into the second arc-shaped groove 25. The rotation angle of the first limiting column 11 is limited by the first arc-shaped groove 24, and the rotation angle of the second limiting column 12 is limited by the second arc-shaped groove 25, so that the limitation of the opening angle of the door body 4 is realized.
The door tongue 22 is inserted into or separated from the slot 41 by the rotation of the door switch 2, so that the door body 4 and the body 1 are locked or unlocked.
As shown in fig. 3 and 4, the door switch 2 further includes a limiting portion 23 disposed at the other end of the door switch body 21, and the blocking component 3 abuts against the limiting portion 23 to limit the rotation of the door switch body 21 in the first preset operation process of the household appliance, so that the door tongue 22 cannot be separated from the slot 41 when an external force acts on the door switch 2.
The blocking assembly 3 comprises a blocking tongue 31 capable of rotating reciprocally relative to the body 1, and a driving piece 32 capable of driving the blocking tongue 31 to rotate reciprocally and connected to the controller; when the blocking tongue 31 rotates to the second preset position, the blocking tongue 31 is pressed against the limiting part 23, so that the door tongue 22 cannot be separated from the slot 41 when an external force acts on the door switch 2; when the blocking tongue 31 rotates to the first preset position, the blocking tongue 31 is separated from the limiting part 23, so that an external force acts on the door switch 2 to unlock and lock the body 1 and the door body 4.
The driving member 32 in this embodiment may be a motor, or may be another member capable of rotating the blocking tongue 31.
The embodiment also provides a method for controlling the door lock of the household appliance, fig. 5 is a flowchart of the method for controlling the door lock of the household appliance according to the embodiment, and the method for controlling the door lock of the household appliance according to the embodiment is specifically described below.
Step one, acquiring the current working process of the household appliance.
Step two, judging whether the current working process of the household appliance is a first preset working process or not.

And thirdly, if the current working process of the household appliance is a first preset working process, the controller locks the door switch 2 of the household appliance, and the body 1 of the household appliance and the door body 4 of the household appliance are kept in a locked state.
That is, the controller controls the driving member 32 to rotate the blocking tongue 31 to the second preset position, and presses the blocking tongue 31 against the limiting portion 23, so that the door tongue 22 cannot be separated from the slot 41 when an external force acts on the door switch 2. The door switch 2 is locked, so that the body 1 and the door body 4 are kept in a locked state.
And step four, if the current working process of the household appliance is not the first preset working process, the controller controls the blocking component to rotate to the first preset position to unlock the door switch 2, and external force acts on the door switch 2 to unlock and lock the body 1 and the door body 4.
The door body 4 is locked only by the door switch 2, and when the door body 4 needs to be opened, the door switch 2 can be acted on by external force to open the door body 4.
In this embodiment, if the dishwasher is provided with a disinfection and sterilization process for disinfecting and sterilizing by ultraviolet rays or ozone, the first preset working process of this embodiment further includes a disinfection and sterilization process, so as to prevent the user from being damaged by ultraviolet radiation or ozone leakage caused by misoperation of opening the door body 4.
Example two
The difference between the present embodiment and the first embodiment is that the household appliance is a washing machine.
If the washing machine does not have a drying function, one duty cycle of the washing machine includes a washing process, a rinsing process, and a dehydrating process. If the washing machine is a pulsator washing machine, the first preset working process includes a dehydration process. If the washing machine is a drum washing machine, the first preset working process includes a washing process, a rinsing process and a dehydrating process.
If the washing machine is a washing machine with a drying function, one working cycle of the washing machine includes a washing process, a rinsing process, a dehydrating process, and a drying process. If the washing machine is a pulsator washing machine, the first preset working process comprises a dehydration process and a drying process. If the washing machine is a drum washing machine, the first preset working process includes a washing process, a rinsing process, a dehydrating process and a drying process.
