In addition, it is more preferable that heaters are respectively provided in the branch pipes.

Therefore, according to the present invention, it becomes possible to wash laundry with excellent washing efficiency and to dry it directly in the washing machine without moving the laundry.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the pulsator type dry washing machine according to the present invention will be described.

Referring to Figure 1, when describing the pulsator type dry washing machine according to the present invention.

First, the components for the washing function for washing laundry will be described as follows.

An inner tub 3 for storing the washing water is installed in the washing machine case 1, and an inner tub 5 in which a plurality of through holes 5a are formed is rotatably installed in the tub 3. The pulsator 7 is rotatably installed in the inside of (5). And the inner tank 5 and the pulsator 7 are rotated by the drive means 9 provided in the bottom face of the outer tank 3.

On the other hand, the upper part of the case 1 is provided with a water supply valve 10 for supplying water for washing and rinsing, the water supply valve 10 is a water supply duct (not shown) for supplying water to the inner tank (5) Connected. A drain duct 11 for discharging the dirty laundry water after the completion of washing to the outside of the washing machine is connected to the bottom of the outer tub 3, and a drain valve 13 is installed at a predetermined position of the drain duct 11. .

Next, the components for drying the laundry will be described.

Between the outer tub 3 and the case 1, a circulation duct 20 for supplying heated air for drying the laundry to the inner tub 5 is installed. That is, the lower end of the circulation duct 20 is connected to the lower end of the outer tank 3, the upper end is located near the upper portion of the inner tank (5).

Of course, a predetermined position of the circulation duct 20 is provided with a heater 15 for heating the air and a blowing fan 22 for forcibly circulating the air. Here, it is preferable that the heater 15 is provided in front of the blowing fan 22 (the discharge port direction of the circulation duct).

On the other hand, the air discharged from the discharge port of the circulation duct 20 to dry the clothes in the inner tank 5 and discharged again to the circulation duct 20 is in a humid state. Therefore, when the air in such a humid state is circulated as it is, the drying efficiency is lowered. Therefore, the moisture contained in the air must be removed during the air circulation.
