JPH05337285A - Lint collector for washing machine - Google Patents

Abstract

PURPOSE:To provide the improved lint collector for washing machine which eliminates the trouble of considerably lowering lint correction efficiency caused by sticking cloth under washing to a liquid sucking port and blocking this port and of considerably decreasing the quantity of sucked washing liquid at the time of lint collection, and which prevents the lint collection efficiency from being lowered even at a low water level in the case of washing a small quantity of laundry. CONSTITUTION:The washing liquid is sucked from a liquid sucking port 23 provided at the bottom part of a washing vessel and passed through a filter 33 incorporated into a stirring blade 14, and a passage is provided for moving the washing liquid passed through the filter 33 to the outer peripheral part of the stirring blade 14 and discharging it after lint contained in the washing liquid is collected into the filter 33.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lint collecting device for a washing machine.

[0002]

2. Description of the Related Art Conventionally, as a technique of this kind, Japanese Patent Laid-Open No.
As shown in Japanese Patent No. 28799, there is provided a filter located at the center of the stirring blade and opening upward.
In addition, a dish-shaped filter is provided at the bottom of the washing tub upstream of the liquid suction port, and the back wing of the stirring blade pumps the washing liquid from above and below the stirring blade to remove lint in the washing liquid. It has been proposed that the above-mentioned filter is used to collect.

Further, as disclosed in Japanese Patent Application Laid-Open No. 60-72598, a filter is attached to a central tower portion of a tall stirring blade, and washing is performed from above the stirring blade central tower portion. At the same time as sucking the liquid and passing it through the filter built in the stirring blade, the lint contained in the washing liquid is collected in the filter, and the washing liquid passing through the filter is put on the outer peripheral portion of the stirring blade. A device having a path for moving and discharging has also been proposed.

[0004]

However, JP-A-56-
According to the configuration described in Japanese Patent No. 28799, when the washing liquid is sucked from above, the cloth being washed is sucked at the same time,
In addition to sticking to the liquid suction port and blocking it, the amount of laundry liquid suctioned is greatly reduced, and the lint collection efficiency is greatly reduced.
When the washing liquid is sucked from below, it is difficult to clean the filter when it is clogged because the filter is installed outside the bottom of the washing tub.

According to the structure disclosed in Japanese Patent Laid-Open No. 60-72598, a filter is attached to the central tower portion of the tall stirring blade, and washing is performed from above the stirring blade central tower portion. Since the liquid is sucked in, there is a problem that the lint collection efficiency is lowered or becomes impossible in some cases at a low water level when washing a small amount.

The object of the present invention is to collect the lint during the washing process by sticking the cloth being washed to the liquid suction port and blocking the liquid suction port. An object of the present invention is to provide an improved lint collection device for a washing machine, which eliminates the problem of a large decrease and does not reduce the lint collection efficiency even at a low water level when washing a small amount.

[0007]

The object is to wash a washing liquid in a lint-collecting device of a washing machine in which a filter is detachably attached in a stirring blade and the washing liquid is circulated by a pump action of a back blade. The liquid sucked through the liquid suction port provided at the bottom of the tank is passed through the filter built in the stirring blade, and at the same time, the lint contained in the washing liquid is collected in the filter, and then the washing liquid passed through the filter. Is provided to the outer peripheral portion of the stirring blade, and the discharge path is provided.

[0008]

In the above-mentioned structure, the washing liquid is pumped by the back blade to be fed into the filter incorporated in the stirring blade through the liquid suction port provided at the bottom of the washing tub, and then the stirring blade It moves to the outer peripheral portion and is discharged.
