Drum-type washing machine

Abstract

The invention relates to a drumble washing machine, which provides a reliable and inexpensive structure of a balance adjusting balancer which eliminates vibration caused by the uneven distribution of laundry in spin-drying. The balancer 20 is attached to the rear part of a rear board 6d of a drum 6, which has a plurality of water storing chambers that are respectively divided by radial partitioning walls in the circumference of a main shaft 7 and respectively provided with an opening for a water flow at an inner peripheral side. A nozzle 30 for pouring water into each storing chamber is arranged in the rear side surface part of an outer tub 3. After the whole water storing chambers are filled with water injected from the nozzle 30, a part of water is discharged by the temporary reduction of the rotary speed of the drum 6 in response to an eccentric load by the uneven distribution of the laundry so that balance is adjusted. The balancer 20 is made of a member obtained by joining two members by thermal melt-sticking, which are divided on a plane being orthogonally crossed with an axis. A double wall structure is adopted in the partitioning walls to be a joining part and an outer peripheral wall so as to prevent the fall of an abutment piece in the case of thermal melt-sticking and also to prevent a break owing to a force which is received from the stored water in the case of centrifugal dehydration.

Description

technical field [0001] The present invention relates to a drum type washing machine having a drum rotating around a horizontal axis or an inclined axis. Most common drum-type washing machines can continuously perform the work from washing to drying, but here, the drum-type washing machine may not have a drying process. Background technique [0002] The drum-type washing machine has a structure in which a cylindrical cage-shaped drum is freely rotatable around a horizontal axis or an inclined axis. During the dehydration operation, the drum containing the wet laundry is rotated at high speed to remove the Moisture flies around and is removed. One of the major problems in such centrifugal dehydration is that when the laundry is not uniformly distributed on the inner peripheral wall of the drum, when the drum is rotated at a high speed, due to the imbalance of the mass distribution around the rotating shaft, the drum or the shaft supports the The outer tank of the drum and th...

Problems solved by technology

One of the major problems in such centrifugal dehydration is that when the laundry is not uniformly distributed on the inner peripheral wall of the drum, when the drum is rotated at a high speed, due to the imbalance of the mass distribution around the rotating shaft, the drum or the shaft supports the Abnormal vibration of the outer tank of the drum and the outer case will cause a large noise, or a large load will act on the bearing or the main shaft itself, which will become the cause of the failure.
