洗濯機
Document Type and Number:
Japanese Patent JP6640611
Kind Code:
B2
Abstract:
A washing machine which automatically supplies an appropriate amount of detergent and softener to each tank according to the amount of laundry provided. The washing machine comprises: a housing (4); a water tank (17) which is inside the housing and has a rotary drum (20) inside; and a washing treatment liquid automatic charging means (30) for supplying detergent into the water tank. By using a DC brush motor as the supply motor (65) and setting the speed reduction ratio to a gear pump (51) appropriately, it is possible to minimize the 'supply amount variation' which is the difference between the maximum supplied amount and the minimum supplied amount per unit time, within a viscosity range from the softener having the smallest viscosity to the liquid detergent having the highest viscosity.
