Abstract

PURPOSE:To enable washing to be efficiently performed and enable washing and drying to be continuously performed by arranging a mechanism for rotating a rotary drum and a mechanism for performing the reciprocating motion of a pair of push plates, and a hot air feeding mechanism for feeding hot air into the rotary drum. CONSTITUTION:The washing and detergent are contained into a rotary drum 12 and water from a feed water pipe 6 is also contained, and a motor 24 is rotated to start washing. In the meantime, when a gear 46A is rotated, the reciprocating motion of push plates 16, 18 is performed in the counter direction, and the washing is rotated. At the same time, it is washed to be rubbed with the push plates 16, 18. After completion of washing working, the rotary drum 12 and the push plates 16, 18 are worked, and at the same time, detergent water is drained, and the water is fed from the pipe 6, and rinsing is performed. When the rinsing is performed, then the motor 24 is rotated in the counter direction. In this case, the driving voltage of the motor 24 is heightened, and dehydration is performed by a centrifugal force due to the high speed rotation of the rotary drum 12. When the dehydration is completed, the driving voltage of the motor 24 is lowered, and the rotational speed of the rotary drum 12 is also lowered. Hot air is fed into the rotary drum 12 from a heater 54 via a pipe 56, and drying is performed.

Since holes are also made in both bottom surfaces of the rotating drum 12, the hot air escapes from the rotating drum 12 to the outside, but it may also be reflected on the wall surface of the water receiving tank 4 and enter the rotating drum 12 again.

The water receiver J44 is made of stainless steel plate or iron plate because it is loaded with weight. The rotating drum 12 is made of heat-resistant plastic so that it can withstand hot air during drying. Examples of heat-resistant plastics include polyvinyl chloride, polyvinylidene chloride, and fluororesin.

Next, the operation of this embodiment will be explained.

Open M62, open the lid 58 at the entrance/exit of the rotary drum 12, put the laundry and detergent in, close the lid 58, and close the lid 62 as well. Add an appropriate amount of water from the water supply vibro, and
Rotate in one direction to start washing. The motor 24 can rotate in both directions, and depending on the direction of rotation during the washing operation, the gears 34A, 46A, 48A rotate with the rotating shaft to transmit rotational force, and the gears 36B, 38B rotate with respect to the respective shafts. Rotates and does not transmit rotational force.

During washing operation, gears 28 and 30 to gear 34A.

The rotational force of the motor is transmitted from the gear 42 to the gear 44 via 46A and 48A, and the 5-rotation drum 2 rotates.

On the other hand, as the gear 46A rotates, the push plate 16.1

8, drain the detergent water and supply water from the vibro to perform rinsing.

When the rinsing is finished, the motor 24 is temporarily stopped with the push plates 16, 18 furthest from each other;
rotates in the opposite direction. At this time, gears 36B and 38B rotate with their respective shafts, and gears 34A and 48A rotate with respect to their respective shafts and do not transmit one rotational force. The rotational force of the motor rotates the rotary drum 12 through the gears 28.30, 36B, 38B and the gear 42.44. The opening voltage of the motor 24 is increased so that the rotational speed of the rotating drum at this time is higher than that during the washing operation. Since the gear 46A does not rotate at this time, the push plate 1
6.18 does not work. Dewatering is performed by centrifugal force due to the high speed rotation of the rotary tram 12.

When dehydration is completed, the driving voltage of the motor 24 is lowered to reduce the rotational speed of the rotary drum 2 while keeping the rotational direction of the motor 24 in the same direction as during dehydration, and the heater 54 is
Hot air is supplied from the shaft 2O through the pipe 56 into the rotary drum 12 through the push plates 16 and 18, thereby performing drying.

(Effects of the Invention) In the present invention, the rotating drum containing the laundry is rotated and the push plate is moved back and forth within the rotating drum so that the laundry can also be washed, thereby improving washing efficiency. , laundry can be done in a short time.
