駄や洗浄性能の劣下という問題がある。Conventional Structure and Problems Conventionally, in a processing agent loading device for a washing machine, a detergent container is used to store detergent for one wash in order to automatically dispense detergent as a processing agent into a washing tub at a predetermined interval. There is a type of washing machine that allows the liquid to be placed inside the washing machine and injected into the washing tub at predetermined intervals. However, with this type of product, it is necessary to measure the detergent and put it into the detergent container every time you wash the clothes.
The work was not convenient. In addition, the detergent container can store several doses of detergent, and an on-off valve and a flow control valve are provided in the path leading the detergent from the detergent container to the washing tub, and the flow control valve is opened in conjunction with the water in the washing tub. There is one that automatically dispenses detergent by changing the degree of detergent and opening the on-off valve at a predetermined timing for a predetermined period of time. However, with this type of device, even if the opening degree of the flow rate control valve is changed in accordance with the amount of water in the washing tub, the resistance of the control valve changes depending on the viscosity of the detergent and the amount of liquid stored in the detergent container. As a result, the amount of detergent that passes within a certain period of time varies, resulting in excess or deficiency of the washing liquid in the washing tub, leading to problems such as wasted detergent and deterioration of cleaning performance.
