Abstract

A wave-wheel washer applicable for frequency conversion technology comprises an inner barrel, an outer barrel and a wave wheel in the inner and outer barrel, a dewatering shaft connected with the inner barrel and a main body of the washer with a clutch having a drainage dragger. The washer is characterized in that the washer comprises additionally a frequency conversion motor, and the clutch is a synchronous clutch, the washing shaft is a cylindrical part whose upper end and lower part are square. In the upper and lower casing of the clutch, from down to up sequentially are a dewatering friction plate assembly fixed on the washing shaft, movable friction plates fixed respectively on the upper and lower part of the slide sleeve of the dewatering shaft, a pressure spring and an adjusting nut looped on the dewatering shaft; the washing friction plate assembly fixed on the joining site of the upper and lower casing is put against the bottom of the slide sleeve together with the roller on the shift fork assembly connected with the drainage dragger. The invention can realize the optimal combination of different washing, rinsing and dewatering, so as to save power, water, wash clean, achieve low wear and high dewatering rate, and the invention has greatly simplified the manufacturing process and reduced the cost.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and more specifically relates to a pulsator washing machine suitable for frequency conversion technology. Background technique [0002] The rotation speed of the washing machine is only more than 100 revolutions per minute during washing, but as high as hundreds or even thousands of revolutions during dehydration. Therefore, the pulsator type washing machine often uses a gear box (reduction clutch) to decelerate, but its structure is complex and costly. Loud noise and low efficiency; almost all current pulsator washing machines use single-phase AC asynchronous motors as power sources. Although single-phase AC asynchronous motors are simple in structure and low in cost, their efficiency is low and speed regulation is inconvenient. [0003] Since there is still no good solution to the speed regulation of single-phase AC asynchronous motors, the stepless regulation of motor speed can be rea...
