Abstract: The present application relates to a door lock and a control circuit thereof. The door lock includes a switch means, a switch driving means capable of opening the switch means, and a driving slider. The driving slider is capable of driving the switch driving means. The driving slider is capable of being driven by a door hook. The switch driving means (that is, a swing lever) and a lock pin are capable of jointly controlling opening of the switch means. The switch driving means (that is, the swing lever) is driven by a mechanical structure (that is, the driving slider), and the lock pin can be driven by an electronic signal and a circuit structure (for example, a second current loop), thereby improving the sensitivity and reliability in disconnecting the power supply under abnormal working conditions.

Abstract: A door lock comprises an electromagnet (410), a latch shaft (320), a crank device (430) and the like. The crank device (430) is connected with the latch shaft (320) and driven by the electromagnet (410) to transform the linear motion of the electromagnet (410) into the rotary motion of the latch shaft (320). When the electromagnet (410) pushes or pulls the crank device (430), a latch head (202) rotates around an axis so that it can move to a locked position or an unlocked position. The door lock (200) of the present invention can transform the linear motion of the electromagnet (410) into the rotary motion of the latch head (202), so that the latch head (202) can be conveniently installed on the lateral surface rather than at an end of the door lock (200). The door lock (200) can be advantageously installed in the middle gap of a front panel (102) along an edge of a control panel of the washing machine (100) to lock the upper cover (101) from the middle part.

Abstract: A door lock and an electrical appliance using the door lock. The door lock comprises: a switch housing; a pen core-like mechanism disposed in the switch housing; a control needle (state means) passing out of the pen core-like mechanism; and a manual unlocking pull rod mechanism. The manual unlocking pull rod mechanism is capable of moving towards the control needle and coming into contact therewith. The position of the control needle (state means) indicates the switch state of the door lock, such that when the door lock is in an unlocked position, further pulling of the manual unlocking pull rod mechanism has no effect on the door lock switch mechanism.

Abstract: The present application provides a door lock, comprising a main sliding block, the main sliding block being able to move to and fro between a locked position and a released position along a first direction (length direction), and the main sliding block being able to lock the door lock when at the locked position, and the main sliding block being able to release the door lock when at the released position; and an indicating sliding block, the indicating sliding block being able to move to and fro between a closed position and an open position along the first direction (length direction) when the main sliding block moves to and fro between the locked position and the released position along the first direction (length direction), wherein the closed position and the open position of the indicating sliding block are used for indicating whether the door lock is in a locked state or in a released state. The door lock of the present application can make the output state of a door lock state indicating apparatus stable.

Abstract: A lock, a lid lock and a locking mechanism are provided. The lock includes a base, and a driving mechanism, a connecting mechanism and a locking mechanism which are provided on the base. The base is buckled to a housing. The connecting mechanism has a first end connected to the driving mechanism, and a second end thereof connected to the locking mechanism. The locking mechanism is rotatably connected to the base to perform a locking operation or an unlocking operation. A return spring is sleeved on the locking mechanism, one end of the return spring is connected to the housing, and the other end to the locking portion of the locking mechanism. The locking mechanism is connected to a control system. In the unlocking operation, the control system determines that the locking portion is disconnected to the return spring according to the locking portion in an unfolded position relative to the base, and determines that the locking mechanism is connected to the return spring according to the locking mechanism in a retracted position relative to the base.
