Abstract

PURPOSE:To peel an adhered washed object off a rotary tank and enable the object to be efficiently dried by rotating a pulsator for a fixed time when the washed object is shifted to a drying process. CONSTITUTION:A pulsator 36 is connected to a driving shaft 37 with a mechanism section 38, and is rotated by the power of a washing motor 40 in a fixed mode. After that, a rotary tank 35 is connected to the driving shaft 37 with the mechanism section 38 in the same manner as that of the pulsator 36, and is rotated at a high speed, and a dehydrating process is executed. In this case, the oscillation of the rotary tank 35 is transmitted to two pairs of suspensions 49 from a water tank 32 via a bearing 48, and is attenuated. When the dehydrating process comes to an end, then a controller 65 is worked, and the pulsator 36 is rotated for a fixed time. By the rotation, a washed object fitted firmly on the internal wall of the rotary tank 35 is partially hooked to a projected section 36a set on the pulsator 36, and is pulled by the rotational force of the pulsator 36, and is peeled off the internal wall of the rotary tank 35. In this state, the controller 65 is worked, and intermittent operation for rotating the rotary tank 35 forward or reversely for a fixed time is performed, and hot air flows to a circulating ventilation flue, and the washed object is dried.

By the counterclockwise rotation of the pinion gear 11 attached to the rack gear 12, the rack gear 12 is moved and the drum shaft 4 is set in a horizontal position to perform the drying process in the horizontal position as shown in FIG. In the drying process, the rotary drum 3 rotates, the laundry is lifted and dropped, and hot air is circulated. Therefore, the laundry items are dried through this drying process.

Problems to be Solved by the Invention However, with such a configuration, when the spin-drying process is finished, the laundry items in the rotating drum 3 adhere to the inner wall of the rotating drum 3 due to the centrifugal force during the spin-drying process, causing Even when the rotary drum 3 begins to rotate in order to agitate the laundry when the drum 3 shifts to a horizontal state and moves to the drying process, the laundry does not separate from the inner wall and remains attached. By this,
The hot air circulating in the rotating drum 3 cannot sufficiently exchange heat with the laundry items, and the laundry items remain wet for a long time without drying.

Therefore, the first object of the present invention is to use a simple structure to separate the adhered laundry items from the rotating tub and to efficiently dry the laundry items. A second object of the present invention is to provide a means for easily peeling off laundry items by controlling the rotation of a rotating tub.

The pulley 62 attached to the output shaft 58 has its other end attached to the water tank 32 and rotates by winding the wire 59! It turns around 1146 and becomes horizontal. In this state, the control device 65 operates and performs intermittent operation in which the rotating tub 35 is rotated forward and backward for a certain period of time, so that the laundry items stuck to the inner wall of the rotating tub 35 are peeled off from the inner wall of the rotating tub 35 by their own weight and rotated. As the tank 35 rotates, it is transferred and diffused. In this state, hot air flows through the air circulation path to dry the laundry items. When drying is completed, the rotating tub 35 returns to the vertical position and is ready for the next washing.

EFFECTS OF THE INVENTION As described above, the washer/dryer of the present invention allows the convex portions of the pulsator to easily peel off the laundry that adheres to the inner wall of the rotating tank at the end of the spin-drying process by rotating the pulsator for a certain period of time. It is something that can be done.

In addition, by keeping the water tank horizontal and rotating the rotary tank intermittently for a certain period of time, the laundry items that have adhered to the inner wall of the rotary tank are peeled off from the inner wall of the rotary tank due to their own weight, transferred and dispersed as the rotary tank rotates, and are transferred into the two-rotation tank. By efficiently exchanging heat with the circulating hot air, it is possible to dry the laundry in a short time.
