DRUM-TYPE WASHING MACHINE
Document Type and Number:
Japanese Patent JPH1176680
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress a vibration at the time of starting dehydration and to reduce the vibration at the time of high speed normal rotation by constituting a drum-type washing machine by means of a balancer ring mounted on the front side of a rotary drum or the rear side outer peripheral part of it, a tube for pouring a fluid into it and a valve for controlling the pouring of the fluid. SOLUTION: The fluid is poured into the balancer ring 21 at an optional timing by closing/opening a water supply valve 23 and the vibration at the time of high speed normal dehydrating rotation is reduced without increasing a transition vibration at the time of starting by executing pouring at the time of starting a dehydrating process especially. Besides, as the fluid to be used in a fluid balancer device, water is adopted. Therefore, special consideration for a water supply source or a drain destination is not required, also the valve being the same as the one for controlling washing water or cooling water for dehydration is used concerning the water supply valve and the water supply system of the balancer device is realized at a low cost. The symbol 22 indicates a water supply pipe for pouring water into the balancer ring 21, the symbol 23 indicates a water supply valve for controlling water pouring and the symbol 24 indicates a water obtaining tube.
