In FIG. 2, the washing machine of the illustrated configuration is, for example, a so-called forced circulation washing machine that circulates the washing water in the tub 4 to the upper side of the tub 4, and laundry is introduced into the cabinet: 1. The basket 3 is rotatably provided, and the tub 4 for storing the wash water outside the basket 3 is provided coaxially. A stirrer 5 is installed inside the basket 3 to invert and rotate by the driving device 6 to generate water flow in the wash water, and a door for opening and closing the basket 3 in the upper part of the cabinet 1. : 2) is installed.

A drain hose 8 for draining the wash water to the drain port 4a of the tub 4 is connected to the drain hose 8. The drain hose 8 opens and closes the drain hose 8 in response to a signal from the controller. ) Is provided. The wash water circulation hose 10 is connected to the drain hose 8 between the tub 4 and the drain valve 9, and the water in the tub 4 is connected to the wash water circulation hose 10. 10 is provided with a washing water circulation pump 11 forcibly circulated to the upper end side thereof.

Meanwhile, according to a feature of the present invention, a lower retainer 12 is installed at the lower side of the tub 4 and connected to the drain hole 4a and the induction hose 14 of the tub 4, and the lower retainer 12 is drained. The inlet side of the hose 8 and the wash water circulation hose 10 are respectively connected. The wash water circulation hose 10 is connected to the upper part of the lower retainer 12, the drain hose 8 is connected to the lower part of the lower retainer 12, and the induction hose 14 is connected to its intermediate position. . In addition, the lower retainer 12 is provided with a filter 13 for collecting lint or foreign matter contained in the circulating wash water, which is preferably located at the inlet side of the wash water circulation hose 10. By being positioned above (14), the reentry of the lint into the basket 3 is blocked.

The filter 13 may be configured in various forms. Preferably, as shown in FIG. 3, the filter 13 may have a plurality of fine flow path holes 13a so as to easily collect and remove lint and the like in the wash water. It is composed of hemispherical shape and arranged convexly downward. Such a filter 13 may be formed by, for example, molding a synthetic resin or the like.

On the other hand, the upper retainer 15 for storing the wash water as necessary in the wash water circulation hose 10 above or below the wash water circulation pump 11, for example, above the wash water circulation pump 11. A retainer valve 16 is installed in the wash water circulation hose 10 to the inlet side of the upper retainer 15 to control the circulation of the wash water in response to a signal from the controller. The remaining reference numeral 7 is a water supply port for supplying washing water into the tub 4.

Operation of the washing machine lint removal device according to the present invention configured as described above is as follows.

First, when laundry and detergent are put into the basket 3 and the washing machine is operated, washing water is supplied into the basket 3 through the water inlet 7, and then the stirrer 5 is reversed by the driving device 6. As a result, water is generated in the wash water, and the washing proceeds by applying an impact to the laundry. At this time, lint or foreign matter generated from the laundry is generated.

On the other hand, when washing is started, the drain valve 9 is closed by a signal from the controller, and the retainer valve 16 in the wash water circulation hose 10 is opened. At the same time, the wash water circulation pump 11 is operated so that the wash water in the tub 4 is forcedly circulated to the upper end of the tub 4 through the wash water circulation hose 10 through the induction hose 14 and the lower retainer 12. Will be. Accordingly, the lint in the wash water generated in the tub 4 flows into the lower retainer 12 along with the circulated wash water, which is collected by the filter 13 in the lower retainer 12 and is purely washed. Tens of thousands of water is introduced into the tub 4 again through the circulation hose 10.

By this operation, lint or foreign matter generated during the washing is surely collected in the filter 13 of the lower retainer 12, thereby improving the washing efficiency in the basket (3).

Meanwhile, when the washing is completed, the washing water circulation pump 11 is stopped and the retainer valve 16 is closed in response to a signal from the controller, thereby storing a part of the washing water in the upper retainer 15. The drain valve 9 is then opened to drain the water in the tub 4. Then, the wash water passes through the lower retainer 12 through the induction hose 14, and the lint and the like collected in the filter 13 are firstly removed by the flow rate and pressure of the wash water being drained. When the next drainage is finished, the retainer valve 16 is opened by the control unit, whereby the wash water stored in the upper retainer 15 is dropped into the lower retainer 12 through the wash water circulation hose 10 to filter ( The lint collected in 13) is removed secondarily.

Therefore, it is possible to reliably collect lint and the like compared to the conventional art, and after the washing is completed, the user can remove lint and the like automatically collected by the drainage of the wash water without directly cleaning the lint collecting filter.

As described above, according to the present invention, it is possible to reliably collect and remove lint and foreign substances generated during washing without having to clean the filter separately after the completion of washing, and separate filter washing water besides washing water It becomes unnecessary. Therefore, the present invention can greatly improve the convenience and washing efficiency of the washing machine, as well as having a very useful advantage of reducing the amount of washing water used.
