| When the control circuit board issued a drainage (or drying) command, the traction motor within the traction motor and anti-reversing electromagnet at the same time work, the motor through the gear group will be wire (or rack) in the tractor, the wire pull The drain valve is drained and the ratchet and the pawl of the clutch assembly having both the washing and drying functions are separated by the mechanical linkage mechanism (while the spin basket lock is released) for the next step of spinning The inner drums are prepared for synchronous rotation (the square wire spring in the ratchet wheel tightens the pulley shaft and inner barrel shaft into one body). Anti-reversing electromagnet charged pull, the linkage mechanism bounce, to ensure that the motor unidirectional rotation will be involved in the wire, and in place when the tractor by the limit switch to stop the motor power, while the electromagnet continue to have electricity Pull, the linkage mechanism to lock the wire to overcome the drainage valve reset spring reverse tension, to maintain the original working condition. When the drainage (drying) process is complete, the control circuit board instructions to power retractor, the anti-reverse mechanism within the release of traction wire in the drainage valve reset spring is pulled out, so that drainage valve closed, linkage The mechanism synchronizes the clutch pawl to engage with the ratchet wheel (the pulley shaft is disengaged from the basket shaft and the clutch is returned to the washing state). |
