Working principle of door lock switch of drum washing machine.(Washing Machine Switch)
The automatic delay door lock is composed of PTC, bimetallic sheet, plastic pin, movable plate, etc. The bimetallic sheet is clamped with the plastic pin.
When the door lock is not powered on, the plastic pin is not inserted into the slot of the movable plate, and the movable plate is not locked. The door can be opened and closed freely.
When the door is closed, the hook on the door pushes the movable plate to the right, and the hook is hooked on the shell of the washing machine.
When the washing machine is powered on, the computer board energizes the L and N ports of the time-delay door lock, PTC generates heat, and the bimetallic sheet is driven by the hot belt. The plastic pin is inserted into the slot of the movable plate to lock the movable plate. At the same time, the bimetallic sheet is connected to port C.
At this time, the movable plate is locked, and the hook on the door cannot move the movable plate to the left, so the door cannot be opened.
After the PLC is powered off, there will be residual heat, and the door cannot be opened at this time. After about 2 minutes, it is no longer hot. The bimetallic sheet is reset, the movable plate is unlocked, and the door can be opened. Micro time delay Switch Electronic Door Lock Door Switch
If the door is not closed and the door lock is powered on first, the plastic pin is butted by the movable plate. Although the bimetallic sheet has been heated, it cannot move. Therefore, port C is not connected, and the computer board will detect that port C has no power and generate an alarm. As soon as the door closed, it was connected.Micro delay door switch lock
The door lock can only be unlocked after cooling for more than 1 minute. Therefore, after washing, the washing machine will display that there is still 1 minute left. This 1 minute is used to cool the door lock. When the display reaches 0 minute and the washing is over, open the door immediately and open the door normally.
