Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lint capturing device that effectively captures lint generated from laundry items during washing and rinsing in a washing machine. A filter for capturing lint is arranged at the suction port of the pump to capture lint, and the water jet from the discharge port of the pump supplements the rotational movement of the laundry object in the washing tank by the pulsator. The purpose is to provide an effective cleaning function.

Conventionally known lint capture devices for washing machines use the water flow of a pulsator in the washing tank to capture lint by inserting a lint capture net into the washing tank. If there are a lot of objects, problems such as the water flow weakening and the lint capture performance decreasing, the net sometimes coming off, or turning over and catching the lint, or the lint redispersing into the cleaning solution. there were.

There was also a system that installed a lint-capturing filter at the overflow port to capture lint while overflowing, but this only captures the lint in the cleaning solution being discharged, and does not remove the lint in the cleaning tank. It is less effective in reducing the concentration of ants, especially those that adhere to laundry items.

Furthermore, in recent years, overflow drains have become an uneconomical means of saving water,
This method has the disadvantage that the lint capture effect is further reduced.Also, blades corresponding to the runners of the pump are formed on the back of the pulsator, and by rotating simultaneously with the pulsator, the circulating water flow is improved. A method was also considered in which a filter was placed in the circulating flow path and the lint was captured by this filter, but in order to increase the circulating water flow with this method, it was necessary to increase the pulsator rotation speed. This creates a paradox in which the laundry to be washed is rubbed more forcefully by the pulsator, accelerating damage and increasing the generation of lint. This method had the disadvantage that it was not possible to increase the circulating water flow, and there was a limit to the amount of lint that could be captured.

There was also a washing machine with a washing method called jet water flow type, but this type of washing machine generally has a circulation pump installed outside the washing tank, and the washing liquid is sucked in from inside the washing tank through a hose or pipe and circulated. The discharge port of the pump is guided into a part of the cleaning tank and the nozzle jets water into the cleaning tank to form a cleaning water stream, which has nothing to do with capturing lint. The drawback is that this method cannot be applied to the cleaning method in which the cleaning method is reversed.

The present invention solves the drawbacks of the jet water type washing machine and effectively captures lint by disposing a circulating water pump in the washing tank to generate water discharge in two directions. Even in the case of an automatic reversal type, the circulating water flow is always in the same direction as the water flow generated by the pulsator.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a lint capturing device according to the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional view of a washing machine equipped with a lint capture device according to an embodiment, and FIG. 2 is a sectional view taken along line A-A in FIG. 1. In the figure, 1 is an outer tank; 2 is a cleaning tank, and 3 is a pulsator.

4 is a motor, and 5 is a motor pulley.The rotation of the motor 4 is transmitted through a belt to a pulsator pulley 6 at a reduced speed, and then through a waterproof bearing 7 to the pulsator 3, and from this pulsator pulley 6 through a belt to a pump pulley 8. The increased rotation speed is transmitted, and the runner 10 is rotated via the waterproof bearing 9.

This runner 1 has two discharge ports, a discharge port 11a and a discharge port 11b, along the inner circumferential wall of the cleaning tank 2, and a pump case 11 which has a suction port 11c above.
It constitutes a pump that generates a circulating water flow within the cleaning tank 2. Then, the pulsator 3 and the runner 10 rotate in the same direction. Reference numeral 12 indicates a filter for capturing lint disposed to cover the suction roll LC. Reference numeral 13 indicates a filter for capturing lint to prevent the lint captured by the filter 12 from touching the laundry and dispersing into the washing tank 2 again. 12, and the part surrounded by this isolation filter 13 and the cleaning tank 2 is the lint capturing chamber 14.

The lint capturing filter 12 and the isolation filter 13 may be integrally molded or may be formed from separate members.
It shall be removable so that it is suitable for use. In the above configuration, during the washing operation of this washing machine,
When the pulsator 3 rotates in an automatic reversing manner, for example, when the pulsator 3 rotates in the B direction, the circulation pump water flow is discharged from the discharge port 11a in the B' direction, and when the pulsator 3 rotates in the B direction, the pulsator 3 rotates in the B direction.
During direction rotation, the circulation pump water flow is from the discharge port 11b to C.
In other words, the circulation pump water flow is always discharged in a direction that supports the pulsator water flow.

Here, the pump pulley 8 may receive immediate rotational transmission from the motor pulley 5, and the circulation pump is driven by a dedicated pump motor (not shown) separately from the motor 4.
It goes without saying that even if this dedicated pump motor is controlled to rotate automatically in reverse using the same program as the motor 4, the same effects as in the above embodiment can be achieved.

As described above, according to the present invention, the rotation speed of the circulation pump runner can be increased without being restricted by the rotation speed of the pulsator as in the past, so it is possible to set a large amount of circulating water. Therefore, the lint capturing performance can be improved. Furthermore, the circulating water flow of the pump can always be set in the same direction as the automatically reversed water flow of the pulsator, resulting in an improved cleaning effect and other great effects not seen in the past.
