AI Technical Summary
Technical Problem
Existing washing machines do not effectively enhance detergency beyond the use of fine bubbles to penetrate deep into laundry fibers.
Method used
A vertical washing machine design with a control unit that rotates the washing tub in one direction at a low water level to generate centrifugal force for deeper bubble penetration, alternates rotor blade directions for agitation, and includes a water supply unit for fine bubble generation and detergent mixing.
Benefits of technology
Enhances cleaning power by deeper bubble penetration and surfactant foam generation, reducing splashing and improving laundry cleaning efficiency.

Abstract
We offer a top-loading washing machine that enhances cleaning power. [Solution] The vertical washing machine comprises an outer tub 3, a washing tub 4, a rotor blade 5, water supply units 14, 40, 60, a drive unit 6, and a control unit 21. The control unit 21 performs a tub rotation process in which the washing tub 4 is continuously rotated in the same direction while water containing fine bubbles is accumulated in the washing tub 4 and the outer tub 3 to a tub rotation water level lower than a predetermined wash setting water level W. After the tub rotation process, the control unit 21 performs a stirring process in which the rotor blade 5 is driven to rotate in the forward and reverse directions alternately at predetermined time intervals while water containing fine bubbles is accumulated in the washing tub 4 and the outer tub 3 to a predetermined wash setting water level W.
