Gradually rotate around. When the water tank 18 becomes horizontal and the limit switch B65 is activated, the rotation motor 49 is stopped. At this time, the guide pulley A60 moves due to the tension of the wire 58 and releases the limit switch A64. In the drying process, the rotating clutch 50 is released and only the blower fan 47 is driven by the rotating motor 49. At the same time, the rotating tub 25 starts rotating at a predetermined rotational speed by the drying motor 37 via the belt B39, causing the clothes inside the rotating tub 25 to roll. At this time, the shutter 72 is in the open state (the seventh
The drying air heated by the heater 67 is blown into the rotating tank 25 to dry the clothes. The heater 67 is provided near the opening at the top of the water tank 18, and the heated drying air is immediately blown into the rotating tank 25, so that very efficient drying can be achieved. Next, when the drying process is finished, the rotating tank 25 is stopped, the rotating clutch 50 is engaged, and the rotating motor 49 rotates in the opposite direction to send out the wire 58 wound around the winding pulley 55. When the water tank 18 becomes vertical, the tension of the wire 58 becomes weaker and the guide pulley A60 is returned to its original position by the spring A62, operating the limit switch A64 and stopping the rotation motor 49. As mentioned above, a series of steps from washing to drying are performed.

The drying air heated by the heater is immediately blown into the water tank, and there is little heat loss (high drying efficiency can be obtained, and the drying air is kept open during the drying process. Since the heater is equipped with a shutter that is closed during the washing, rinsing, and spin-drying processes, bubbles from water and detergent do not come into contact with the heater, resulting in extremely high reliability and safety. be.
