Abstract

The outer cylinder (9) has an outer layer cover (9a) provided with a waterway component (50). Tap water is supplied from the water supply unit to the water channel member (50). In addition, the side water spray port (50b1) that indirectly sprays water to the outer peripheral edge of the balance ring (8c) of the washing and dehydrating cylinder (8) is formed on the water channel member (50), and a water spray port (50b1) is formed on the balance ring (8c) in addition. ) on the side of the upper side of the water spray on the bottom side of the water outlet (50a1). The tap water sprayed on the outer peripheral portion of the balance ring (8c) is scattered to the inner peripheral surface (9s) of the outer cylinder (9) due to the centrifugal force when the washing and dehydrating tub (8) rotates. The running water that hits the inner peripheral surface (9s) flows down the inner peripheral surface (9s) due to the effect of gravity.

Description

technical field [0001] The present invention relates to a washing machine having a function capable of cleaning a drum. Background technique [0002] Among the washing machines (washing dryers), there are washing machines (washing dryers) that can set a program for washing the drum that is different from the washing operation because dirt adheres to the inner tub and the outer tub. However, in the program aimed at cleaning the cartridge, chemicals for cleaning are required, and the user is required to select a cartridge cleaning program, etc., making the cleaning operation complicated. [0003] Therefore, as another method of cleaning the drum of a washing machine (washing dryer), the following technology has been proposed: installing an air bubble spraying device at the bottom of the outer drum to inject air bubbles to the dirt while water is accumulated in the outer drum, thereby Stain removal (refer to Patent Document 1). [0004] prior art literature [0005] patent d...
