Abstract

A washing machine (50) in which, at the start of a washing operation, a control unit (25) determines a first water quantity of washing water and a detergent quantity, in accordance with a quantity of laundry detected by a clothing quantity detecting unit, generates a high-concentration detergent solution using a second water quantity, less than the first water quantity, of washing water, supplies the high-concentration detergent solution to a foam-generating unit (16), and executes an impregnation step of introducing the foam generated by the foam-generating unit (16) into a rotating drum and causing the foam to be impregnated into the laundry. Further, the control unit (25) is configured in such a way that if the quantity of laundry detected by the clothing quantity detecting unit is greater than a prescribed quantity, the control unit (25) sets the second water quantity to be greater than a prescribed water quantity.

Description

technical field [0001] The invention relates to a washing machine for washing laundry and the like. Background technique [0002] In the conventional washing machine, it is considered to dissolve the detergent in a small amount of water and to infiltrate the detergent solution with a concentration higher than that of the washing water in the washing process into the laundry in advance, thereby utilizing The chemical cleaning power of the detergent that acts on the dirt to improve the cleaning efficiency (for example, refer to Patent Document 1). In the washing machine described in Patent Document 1, the detergent concentration of the detergent solution permeating the laundry is set to be 5 to 30 times the detergent concentration of the washing water. [0003] In addition, it is conceivable that a detergent solution obtained by dissolving detergent in water becomes foam and adheres to and permeates laundry in the rotary drum (for example, refer to Patent Document 2). The dr...
