Drum type washing machine

Abstract

The invention provides a drum type washing machine equipped with a displacement detecting means for detecting the displacement of a water tub with accuracy so as to cause neither abnormal vibration nor abnormal noise by the vibration of the water tub holding a rotating drum, due to the unbalance or the like of a washing. A water tub unit 7 is supported in a position closer to the front face side than the center-of-gravity position by a vibration control damper. The water tub unit 7 is disposed in a swingable manner in a washing machine casing 6, and a displacement sensor 36 is disposed on the back face side rather than the vibration control damper 70 and on or near a hanging line from the center-of-gravity position of the water tub unit 7. Since the displacement of the water tub unit 7 is accurately detected by the displacement sensor 36, operation control causing neither abnormal vibration nor abnormal noise can be performed.

Description

technical field

[0001] The invention relates to a drum type washing machine which completes various operation processes such as washing, rinsing and dehydration by driving a rotary drum containing laundry to rotate. Background technique

[0002] In the front-loading washing machine, since the rotating drum is installed in the tub so that its axis of rotation is in the horizontal direction or the front part is tilted up from the horizontal direction, if the rotating drum is loaded with laundry and then rotated, washing Things and water will be partial to the lower part, and it is easy to vibrate. In particular, when the rotating drum is rotated at a high speed for dehydration, the rotating drum contains laundry that has just completed the washing operation and still contains water, and the type, texture, or shape of the laundry is very different. The laundry is easily gathered / biased to one side in the rotating drum during the rotation of the operation. When the laundry is ...
