Open door 9 with the clothing cylinder 3 of packing into.Then, the washing powder of scheduled volume is packed into washing powder box (not shown).By opening water supply hole, with washings and the washing powder wash bucket 2 of packing into.Then washings are sent in the space that forms between cylinder 3 and cylinder 3 and the wash bucket 2, until predetermined altitude.
Through behind the said process, make the heater energising that is installed in wash bucket 2 bottoms, thereby washings are heated to predetermined temperature.
Starter motor 6 then, and wherein the moment of torsion of motor 6 is passed to cylinder 3 by drum shaft 4 and bearing 5, thus swing roller 3.When motor 6 was direct linkage type, motor 6 was arranged in the wash bucket rear side.When motor 6 was the belt transmission type, it was usually placed in wash bucket bottom in the casing.
When cylinder 3 rotations, the lifter (not shown) makes the clothing in the cylinder 3 rise when rolling, descend.At this moment, the hot washings in the cylinder 3 flow along the inner periphery of cylinder 3, thus moistening equably laundry.
After the laundry change is wet, the beginning washing operation.The advantage that such tumbling-box washing machine has is, because the increase of frictional force between clothing and cylinder that lifter causes can improve detersive efficiency.Same because warm water has activated washing powder, also improved efficient.
After wash cycle was finished, the washings in the wash bucket 2 were discharged by scupper hose 12 by draining pump 13.Then, the clear water of scheduled volume injects wash bucket 2 by water supply hole, then cylinder 3 rotation preset times.Thereby such operation repeats repeatedly to carry out rinse cycle.
After rinse cycle was finished, the washings that rinse cycle is used drained into the outside by pump 13.Cylinder 3 rotates once more carrying out dewatering cycle then, thereby the water in will doing washing is deviate from.
