Abstract

PURPOSE: To improve washing performance and to reduce a washing water amount relating to washing liquid by forming a plurality of intakes opened in a rotating direction on the bottom surface of an agitation blade provided with a tower-like body on a center part, utilizing a dynamic pressure generated by rotation and performing washing while sprinkling the washing liquid to cloths from the upper part of the tower-like body. CONSTITUTION: When the cloths and a detergent are fed, the water of about 3-8 times of cloth weight is supplied and the agitation blade 11 is turned, when the rotating direction is on a left side viewing from the lower side of the agitation blade 11, the washing liquid is taken into the agitation blade 11 from the intake 37, passing through a room 17 and a communicating path 15 to push up a check valve 20, passing through a water well part 36 and discharged from a sprinkling port 19 in an outer peripheral direction further, and washing is performed while impregnating the cloths with sufficient washing liquid. Also, at the time of the inverse rotation of the agitation blade 11, the check valve 20 is closed, the state of retaining the washing liquid inside the water well part 36 is maintained and preparation is performed for the time of normal rotation capable of water intake from the intake port 37. At the time of shifting to a dehydrating operation, the water inside the water well part 36 is discharged from the sprinkling port 19 to the outside by the up spread taper of an inner wall and the centrifugal force of the agitation blade 11 rotated at the same speed as a washing tank 8.
