The present invention is to attach the light emitting element and the light receiving element to the inlet of the drain pipe to detect the contamination of the wash water to wash the contaminated water and foreign matter adhered to the wall of the drain pipe during the rinsing administration, in particular the clean tube before the rinsing operation in the washing stroke ( The present invention relates to a method for washing foreign substances in a washing machine drain pipe so that more accurate contamination can be detected during rinsing by directly supplying water to a variable side through a clean tube) to wash the drainage side and discharge the washed water outward.

In general, the washing machine has a water supply valve 13 for adjusting the amount of water supplied to the washing tank through the water supply pipe 6 as shown in FIG. 1, and a number for controlling the washing tank in the washing tank to drain through the drain pipe 3. The valve 2, the pulsator 11 for mixing the wash water and the laundry during washing and rinsing, and the pulsator 11 for rotating the washing and rinsing under the power of the motor 10 generating power. And a belt 9 for rotating the inner washing tank 7 and the pulsator 11 at the same time when the drain valve 2 is turned on, and a belt for transmitting the power of the motor 10 to the clutch 9. (12) and the light emitting element (4) and the light receiving element (5) attached to the drainage side to detect the turbidity of the wash water, and the bubbles attached to the wall of the drainage dilution or contaminated water remaining in the drainage side during water supply Connected between the water supply pipe (6) and the drain pipe (3) to clean the dirt, Is composed of the cleaners tube (Clean tube) (1).

In the washing machine having such a configuration, light incident on the light receiving element 5 in accordance with the turbidity of the wash water when the washing light emits a predetermined amount of infrared rays from the light emitting element 4 and passes through the drain pipe 3. As the voltage of the light receiving element 5 is changed as the value is adjusted, the contamination level of the wash water is determined as the data of the light receiving element 5, and the washing time and the left and right inversion time of the pulsator 11 are adjusted to wash. To complete and enter the rinse stroke.

After the washing process is completed and during the rinsing cycle, the inside of the washing tank and the dirty washing water are first turned on by driving the drain valve 2 to be discharged to the outside, and then the inner washing tank 7 is rotated to dehydrate the laundry and dewater through the drain pipe 3. Drain one wash water.

After the dehydration operation during such rinsing, as the drain valve 2 is turned off and the water supply valve 13 is turned on, a part of the water supplied when the washing water is supplied into the washing tank through the water supply valve 6 is a clean tube (1). Flow into the drain pipe (3) to dilute the contaminated water remaining in the drain pipe (3) or to wash off any bubbles or dirt adhering to the wall of the drain pipe (3).

Referring to the operation again based on FIG. 2, after the washing process, the washing water is drained and the motor 10 is turned on to dehydrate the laundry, and after the dehydration is completed, the motor 10 and the drain valve 2 are removed. Turn off then supply water.

After the water is supplied as in the above operation, the rinsing cycle is entered.

However, after performing such a dehydration operation in the conventional rinsing stroke, when the drain valve is turned off, the water supply valve is turned on, and water is supplied to the washing tank through the water supply valve 6, a part of the water to be supplied is a clean tube (clean). It flows into the drain pipe through the tube and removes the bubbles and dirt adhering to the wall of the drain pipe, but as the drain valve is turned off during water supply, the bubbles and dirt are diluted but not completely discharged to the outside. This becomes impossible, and it takes a considerable time to push the contaminated water inside the drain pipe in the direction of the washing tank by the water entering through the clean tube, thus making it difficult to proceed with the correct rinsing stroke.

In order to solve such a conventional difficulty, the present invention is to perform the water supply operation for a predetermined time while the drain valve is open after dehydration during the rinsing administration process so that the water supplied through the clean tube washes the drain pipe wall and the washed water. Invented to clean the foreign matter in the washing machine drain pipe to enable more accurate detection of the laundry consignment during the rinsing by discharging to the outside, described below with reference to the accompanying drawings.

The structure of the washing machine in the present invention is the same as the configuration described on the basis of FIG. 1 and the operation will be described with reference to FIG.

After the washing stroke is completed, the drain valve 2 is turned on and then washed to discharge the dirty laundry water to the outside. When the drainage is completed, the motor 10 is driven while the drain valve 2 is on. 9) The pulsator 11 and the internal washing tank 7 rotate together to rotate, thereby performing dehydration operation. After dehydration is completed for a predetermined time, the motor 10 is turned off to complete the dehydration operation of the internal washing tank 7 after a predetermined time. Wait for inertia rotation time.

When the inertia rotation of the predetermined time is over, the drain valve 2 remains on and the water supply valve 13 is turned on to start supplying water. The water is supplied to the internal washing tank 7 through the water supply pipe 6 and at the same time. Part of the water flows into the drain pipe through the cland tube (1).

At this time, the water entering the drain pipe (3) washes off foreign matters such as when lapping on the wall of the drain pipe (3) and soap bubbles and is discharged to the outside. After this operation is performed for about 10 seconds, the drain valve 2 is turned off and water supply for rinsing operation is performed.

Referring to the method of removing foreign substances as described above based on FIG. 3 again, a part of the water supplied to the internal washing tank 7 by supplying water with the drain valve turned on without turning off the drain valve immediately after dehydration during the rinsing operation Initial turbidity data when detecting turbidity of wash water by using light emitting device and light receiving device when re-water is supplied by washing the wall of drain pipe by flowing directly through drain tube through drain tube. It can be used as basic data to detect washing water when rinsing.

As described in detail above, the present invention performs a water supply operation in a state in which a drain valve is opened after dehydration during a rinsing operation so that a part of the water supplied flows directly into a drain pipe through a clean tube, and the water drains the wall of the drain pipe. By washing and immediately discharging to the outside, washing water turbidity detection is more accurately detected during subsequent rinsing.

Claims (1)

The first step of checking whether dehydration is completed after the washing process and the draining process during the rinsing operation, and when the dehydration is completed in the first step, water is supplied for a predetermined period of time through the clean tube while the drain valve is opened. Washing and draining the washed water to the outside, and after the second step of the drainage valve, the third step to continue the rinsing process after the water supply is performed in the washing machine drainage pipe, characterized in that How to clean foreign objects.
