The conventional washing and drying machines are:
In the dehydration process before shifting to the drying process, the laundry is strongly pressed against the inner wall surface of the washing and dewatering tub by receiving a large centrifugal force, so even if the amount of laundry is small or the amount of laundry is large. In case of high dispersion in the height direction of the washing and spin-drying tub, the laundry located at the bottom of the washing and spin-drying tub,
In some cases, the rotor did not come into contact with the outer peripheral edge. In such a state, when the process shifts to the next drying and drying process, the laundry is not scraped off from the inner wall of the washing and dewatering tub due to the rotating operation of the rotary wing, and sticks to the inner wall of the washing and dewatering tub. The process proceeds in this state.

Since the rotation speed of the washing and dewatering tub is 300 rpm and the centrifugal force is small, the laundry only contacts the inner wall surface of the washing and dewatering tub lightly and is stacked. There is an advantage that hot air enters the area near the wall of the washing and dewatering tub and the drying speed is high, but since there is no effect of centrifugal dewatering, all the moisture contained in the laundry is vaporized with the hot air. As a result, there is a problem that the energy efficiency is not good and the drying time is long.

Furthermore, if the number of rotations of the washing and dewatering tub is set to be large and the centrifugal force generated by this rotation is increased,
The moisture contained in the laundry is removed from the laundry by centrifugal dehydration at the beginning of drying, but the effect of centrifugal dehydration disappears over time,
It comes into contact with warm air while sticking to the inner wall of the washing and dewatering tub. Even with such a drying method, the surface of the laundry that is in direct contact with the warm air evaporates and the drying proceeds.However, since the centrifugal force is large, the laundry is pressed strongly against the inner wall surface of the washing and dewatering tub to form a laminated state. There has been a problem that the finished quality of the laundry is poor, such as wrinkles on the articles and uneven drying.

Although the operating state of the rotary wing 19 is shown in a rectangular shape, the present invention is not limited to this.
The rotation state at the time of stop (at the time of inertial rotation) naturally changes with time. The timing of alternately switching between the washing and dewatering tub 15 and the rotary wings 19 can be set as appropriate, such as driving the rotary wings 19 after the washing and dewatering tub 15 is completely stopped. Further, one rectangular shape of the rotary wing 19 includes the operation timing chart of forward / reverse rotation shown in FIG.

High-speed rotary drying of the washing and dewatering tub 15
3, the centrifugal dewatering effect, which depends on the conditions of centrifugal dehydration such as the number of revolutions of the washing and dewatering tub 15 and the wall shape, gradually decreases with time, and the centrifugal dehydration effect evaporates and diffuses water due to warm air. The time until the drying speed becomes lower than the drying speed is experimentally obtained and set. Alternatively, the high-speed rotation of the washing and dewatering tub 15 is switched to the low-speed rotation based on the information that it is determined that the water droplets of the centrifugal dehydration do not hit the outer tub 2 or that it is determined that the water droplets have disappeared at the drain port.
