The washing machine enters a certain mode selected by the user and puts the laundry in the washing tank. The amount is detected and the detected amount of water is introduced through the valve. At the same time, the detergent inlet is activated and the detergent in the inlet is discharged to the washing tank in a fixed amount with water. Afterwards, after washing for a certain time, the washed dirty water is discharged through the drain pipe, and then the water is introduced again and undergoes several rinsing cycles. When the set number of rinses is completed and the water is completely discharged, all steps for washing are completed while dehydrating while strongly rotating the washing tank.

However, the conventional fully automatic washing machine is configured to automatically control all steps of washing, rinsing, and dehydration, but when the rinsed laundry is rinsed, there is no device for adding the fabric softener. . The direct addition of the fabric softener acted as a factor causing the environmental pollution because the user did not recognize the quantity correctly, and the addition of the fabric softener should be carried out in the rinsing step, but it is often inadvertently omitted. It was.

Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to provide an automatic feeding device for the fabric softener of the washing machine to automatically put a quantity of softener together with the inflow of water at the time of rinsing the cloth. .

The present invention devised to achieve the above object is provided with a valve connected to the faucet and pipe in the upper portion of the outer cylinder to control the water to be introduced into the washing tank, the close position of the valve is a detergent with the inflow of water during washing In the washing machine provided with a separate detergent inlet to be introduced,
