The present invention relates to a water supply system and a water supply control method of a water purifier, in particular, when the contaminated water is backwashed, the performance of the filter is not only degraded, but also when the contaminated water remaining on the water purifier or pipeline is washed. The present invention relates to a water supply system and a water supply control method of a water washing machine for preventing reflowing and damaging cloth. As shown in FIG. 1 and FIG. 2, a one-touch (O / T One Touch) hose l3 and an inlet hose 6 connected to the water cock 14 are provided. One end of the water inlet hose 6 is connected to the water purifier 1, the other end of the water purifier 6 connected to the inlet hose 6 is connected to a water supply hose 8, and the inlet hose (6) and the water supply hose (8) are each branched and connected to the backwash hose (7), and branched again between the branch point of the inlet hose (6) and the backwash hose (7) and the water purifier (1) to drain hose. (9) is connected. In addition to this, a solenoid valve 1 (2) is provided between the backwash hose 7 and the drain hose 9 on the inlet hose 6, and the backwash hose 7 on the water supply hose 8 is provided. The solenoid valve 2 (3) is provided in the rear stage, and the solenoid valve 3 (4) is installed on the backwash hose 7 and the solenoid valve 4 (5) is installed on the drain hose 9.

Looking at the conventional technology configured as described above are as follows.

Conventional water supply methods can be roughly divided into general washing and purified water washing.

First of all, when looking at the water supply period during general washing, only the solenoid valve 3 (4) and solenoid valve 2 (3) is turned on while the solenoid valve 1 (2) and the solenoid valve 4 (5) are turned off. Accordingly, when the one-touch hose 13 connected to the water cock 14 is opened and the water supplied is introduced into the backwash hose 7, the water is again shown in FIG. 1 through the water supply hose 8. Water is supplied to the washing tank 11.

In other words, this is to supply water into the washing tank 11 that flows through the tap without immediately purifying the water through the water purifier 1,

Second, in the case of water washing, as shown in FIGS. 1 and 2, unlike the general washing, the solenoid valves 1, 2 (2) (3) are turned on and the solenoid valves 3, 4, (4) ( When 5) is turned off and the water enters through the water cock 14 and the one-touch hose 13, water is supplied from the water supply hose 6 to the water purifier 1. Accordingly, the water is purified in the water purifier 1 for a predetermined time, and the purified water is supplied to the washing tank 11 of the washing machine through the water supply hose 8.

The water supply method at the time of water washing as in the above operation will be described below with reference to the flowchart shown in FIG. 3.

When washing water, turn on the solenoid valves 1, 2 (2) and (3), supply water to the water purifier (1), check if a certain time (t) has elapsed. If so, then the water level of the water supplied into the washing tank 11 is sensed.

When the detected water level is above the set level, the solenoid valves 1, 2 (2) and (3) are turned off, and the solenoid valves 3, 4 and (4) and (5) are turned on so as to enter the intake hose (6). Water entering the water purifier (1) through (7) is passed back to the drain hose (9) while the water purifier (1) to backwash.

In such backwashing, the solenoid valves 3, 4, and (4) (5) are turned off and closed after the set time to terminate the water supply.

However, in this conventional technique, since the condition of the water to be supplied is not known in advance, water purification should always be performed in areas where water quality is concerned, so the life of the water purifier is shortened, and the backwash is always performed after a certain amount of water supply. When the contaminated water enters, the inside of the water purifier is contaminated and affects the life, and when the water is rinsed again, the laundry is recontaminated by some contaminants remaining in the inside of the water purifier and on the water supply line, and the life and performance of the water purifier For this, there was a big problem that the user has to manually select the water purification and general washing according to the water quality and the possibility of inflow of contaminated water.

Therefore, in order to solve the conventional problems, the present invention is equipped with a water quality sensor on the water supply line to change the water channel according to the water quality of the water to be used only when the water purifier is needed so that the efficient use of safety washing and water purifier Invented a system and a water supply control method of the water supply of the water washing machine to increase the height, it will be described in detail below with reference to the accompanying drawings.

4 is a system configuration diagram of the water supply washing machine of the present invention, which connects the one-touch (O / T One Touch) hose 13 and the intake hose 6 connected to the water cock 14, as shown therein. One end of the inlet hose 6 is connected to the water purifier 1, the other end of the water purifier 6 connected to the inlet hose 6 is connected to the water supply hose 8, the inlet hose (6) And the water supply hose (8) are branched and connected to the backwash hose (7), and the water quality sensor (10) is attached between the one-touch hose (13) and the backwash hose (7) branch point of the inlet hose (6). And branched again between the branching point of the inlet hose 6 and the backwashing hose 7 and the water purifier 1 to connect the drain hose 9 to the backwashing hose 7 on the inlet hose 6. A solenoid valve 1 (2) is installed between the branch and the drain hose (9) branch point, and a solenoid valve 2 (3) is installed after the backwash hose (7) branch point on the water supply hose (8). Constitute by installing the solenoid valve 3 on the hose (7) (4), the drain hose 9, the solenoid on the valve 4 (5).

The turbidity detection step of detecting turbidity of the water quality while draining the water supplied in the flow chart shown in FIG. 5 with respect to the operation and effect of the present invention configured as described above, and the turbidity detected by the turbidity detection stage is less than the set turbidity The water supply step of supplying water to the set water level through the backwash hose and the water supply step of supplying water to the water level through the water purifier when the turbidity detected in the turbidity detection step is higher than the set water turbidity are as follows.

When water for washing starts, first, solenoid valves 1, 4 (2) and (5) are turned on, and the water supplied through the water cock (14) is bypassed for a predetermined time from the inlet hose (6) to the drain hose (9). The water turbidity is checked with the water quality sensor 10 installed on the inlet hose 6 while being bypassed for a predetermined time.

If the turbidity of the water checked in the above procedure is suitable for washing, turn off the solenoid valves 1, 4 (2) and (5), turn on the solenoid valves 2, 3 (3) and (4) and immediately enter the inlet hose (6). Water is supplied directly to the washing tank 11 via the backwash hose 7 and the water supply hose 8.

When the water is supplied to the washing tank 11 and the water level in the washing tank 11 is sensed and the water level is higher than the set water level, the water quality sensor 10 sets the turbidity value of the water supplied to zero. Then, the water supply is completed by turning off the solenoid valves 2, 3 (3) and (4). If the water level is lower than the set water level, water is supplied while continuously checking the turbidity of the water and the water level in the washing tank as described above.

If the turbidity of the water is above the set turbidity, the solenoid valve 4 (5) is turned off, and the solenoid valve 2 (3) purifies the water supplied to the water purifier 1 through the water inlet hose 6 for a predetermined time. The turbidity of the water at this time is sensed while supplying the water to the washing tank (11).

When the turbidity of the water is less than or equal to the set turbidity, the solenoid valve 1 (2) is turned off and the solenoid valve 3 (4) is turned on to purify the water supplied to the water purifier 1 through the inlet hose 6 for a predetermined time. While supplying this purified water to the washing tank 11, the turbidity of the water at this time is sensed. When the turbidity of the water is less than the set turbidity, the solenoid valve 1 (2) is turned off and the solenoid valve 3 (4) is turned on so that the water supplied is supplied directly to the washing tank 11 without passing through the water purifier 1 at that time. Detect it.

If the water level is higher than the set water level, set the turbidity to zero and turn off the solenoid valve 2 (3) and turn on the solenoid valve 4 (5). In (6), the water purifier (l) is washed backward from the rear end via the backwash hose (7), and the solenoid valve (3), (4), ( Turn off 5) to finish watering.

If the water level is below the set level, turbidity check and water level detection using the water quality sensor (10) are repeated and water supply is performed. Turn off (3) and finish the water supply without backwashing and turbidity zero setting.

Looking at the water supply control method as described above with reference to Figure 5 as follows.

When water is supplied, the solenoid valves 1, 4 (2) and (5) are turned on and the solenoid valves 2 and 3 (3) and (4) are turned off to drain the water supplied through the water cock for a predetermined time and the water quality sensor (10). As the first turbidity detection step of checking and detecting the turbidity of water, and if the turbidity of water is less than or equal to the set turbidity in the first turbidity detection step, the solenoid valves 1, 4 (2) and (5) are off solenoid valves 2 and 3 (3) ( 4) turns on the water supply to the washing tank 11, the first water level detection step of detecting the water level of the water supplied water, and if the water level in the washing tank 11 in the first water level detection step is higher than the set water level solenoid valve 2,3 (3) (4) is turned off to terminate the water supply, and if it is below the set water level, the flow proceeds to the first water supply step proceeding to the first turbidity detection step.

In the first turbidity detection step, if the turbidity of the water is equal to or greater than the set turbidity, the solenoid valve 4 (5) is turned off and purified through the water purifier 1, and then the solenoid valve 2 (3) is turned on to provide turbidity of water supplied to the washing tank 11. When the turbidity of the water in the second turbidity detection step and the second turbidity detection step is below the set turbidity, the solenoid valve 1 (2) is turned off solenoid valves 3, (4) is turned on to supply water to the washing tank (11) The second water level detection step for detecting the water level at that time, and if the water level in the second water level detection step is higher than the set water level, the turbidity at this time is set and then the solenoid valve 2 (3) is the off solenoid valve 4 (5) After washing the water in reverse after the water purifier 1 supplied for a predetermined time, the solenoid valve 3, 4 (4) (5) is turned off to proceed to the second water supply stage to complete the water supply.

Then, if the water level is lower than the set water level in the second water level detection step, water supply is continuously supplied to the turbidity detection and water level detection. If the water level is continuously set in the second turbidity water detection step, the solenoid valve 1, 2 ( 2) (3) is turned off and the water supply end step is completed.

Therefore, you can always wash with clean water and extend the life of the water purifier.

As described in detail above, the present invention is equipped with a water quality sensor on the water inlet hose connected to the cock cock discharged out for a predetermined time for the water to be initially supplied, then detect the turbidity of the water with the water quality sensor, the turbidity is set below the turbidity If the water is immediately supplied to the washing tank so that washing is possible, and if the turbidity is higher than the set turbidity, the water is purified through the water purifier and the water is supplied to the washing tank so that it can always be washed with clean water, and the water purifier can be used most efficiently. By backwashing only with clean water, the life of the water purifier can be extended and the turbidity value is always reset at the last stage of washing while the water quality is clean, thereby preventing the water quality reading error due to contamination of the sensor part.
