The present invention relates to a water supply control method of a fully automatic washing machine, and more particularly, it is possible to shorten the water supply time during washing by using a fully automatic washing machine in a high water pressure zone.

In the conventional fully automatic washing machine, as shown in FIGS. 1 and 2, the first gas flow path 17, which is a supply path for ozone gas, is a silicone hose in the ozone gas generator 10a installed on the top of the tub 2a. The second gas passage 18, which is a supply passage of the raw material gas including oxygen gas, is connected to each other so that the ozone gas generator 10a is connected to the first gas passage 17 from the raw material gas introduced through the second gas passage 18. Acts to generate ozone gas, and flows from the first gas passage 17 to the ozone gas generator 10a in the first gas passage 17 between the ozone gas generator 10a and the gas-liquid mixing passage 19. A check valve 11a is provided to stop the flow of water and to pass the ozone gas from the ozone gas generator 10a, and the ozone gas generated by the ozone gas generator 10a is transferred from the ozone gas generator 10a. It is supplied to the gas-liquid mixing path 19 through the first gas passage 17.

In addition, the gas-liquid mixing passage 19 communicating with the first gas passage 17 and the water supply passage 20 is provided with an orifice 21 at both ends to form a negative pressure state of the gas-liquid mixing passage 19. The ozone gas flowing into the gas-liquid mixing passage 29 through the gas flow passage 17 is mixed with water in the gas-liquid mixing passage 19.

However, such a conventional fully automatic washing machine is not provided with a structural device capable of removing ozone gas that has not occurred in the tub 2a due to ozone hydration. In particular, the generated ozone gas and ozone water are introduced from the upper part of the washing machine. Due to the free fall, the amount of unnecessary ozone gas is increased, so the washing machine user is in a safe state and cannot perform efficient washing work. There were many problems such as not to generate ozone water.

The present invention is to solve the above-mentioned problems, the present invention is built into the automatic washing machine water supply time compensation program to prevent water supply errors caused by the longer water supply time when washing in the low-pressure highlands, etc. to greatly increase the overall washing time It is an object of the present invention to provide a water supply control method of a fully automatic washing machine that can be shortened.

In order to achieve the above object, the present invention provides a first step of supplying water by setting a minimum water level, a water level, and a water supply error limit time; The second step of determining whether the water level has been reached; and if the lowest water level has not been reached in the second step, the water supply error is displayed and terminated. If it reaches, the water supply time is reached until the set water level is reached, and the water supply time when the water level is reached is reached. A third step of memory, a third step of proceeding washing, draining, and intermittent dewatering strokes when water supply is completed in the second and third steps; and a rinsing stroke until the compensated water supply time is compensated by compensating the memorized water supply time. The fifth step of resupplying water and the level of the water resupplied in the fifth step is lower than the water level set in the first step. If it is not determined that the water supply time is reached, the water supply is extended for a certain time from the stored water supply time, and if the water supply time is not reached, the sixth step of displaying and terminating the water supply error is reached. A water supply control method for a fully automatic washing machine comprising a seventh step of performing a rinsing stroke, draining, and dehydration.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 3 to 6.

In the automatic washing machine, a box 3 having a built-in water supply and ozone generating function is integrally installed at the top of the top cover 2 on the main body 1 and detachably installed. One side of the box 3 has cooling water for cooling. An ozone gas generator (5) having a pipe (4) built therein to generate ozone gas is mounted. On the other side of the box (3), a water filter (6) for purifying the water supplied therein is built in the bottom of the box (3). A water purification tank 10 is formed in which a connection pipe 9 communicating with the first valve 8 on the top cover 2 protrudes in and out through the first discharge hole 7. The cap 11 is inserted in the upper part of the connecting pipe 9 so that a proper space is maintained for the fluid to flow.

In the upper part of the box 3, a gas-liquid mixer 12 for mixing the water and the suctioned ozone gas during water supply is installed, and the ozone gas that is not dissolved but separated from the water in the upper center of the purified water dissolution tank 10 is installed. A catalytic filter 13 for reducing oxygen gas is installed, and a water supply port 14 is installed at an upper side of the box 3.

In addition, a water supply valve 16, which is a two-way valve that is in communication with the water inlet 14 and selectively opened and closed to supply water to the tub 15 in the main body 1, is installed at one upper side of the box 13. On the one end of the outlet 16 is branched by the Y-connector 17 and the second valve 19 on the top cover 2 through the water purification tank 10 and the second discharge hole 18 below the box 3. The other side of the water supply valve 16 is connected to one side of the gas-liquid mixer 12 via the water cooling tube 4 of the ozone gas generator 5, and the other side of the gas-liquid mixer 12 is a water purification tank. Communicating with the upper one side of (10).

In addition, between the upper center of the gas-liquid mixer 12 and one side of the upper portion of the ozone gas generator 5, a check valve 20 and a third valve 21 for air are provided, and the upper portion of the water purification tank 10 A fourth valve 22 is installed between the lower portions of the catalyst filter 13, and a cover 23 that is opened and closed at the time of filter replacement and troubleshooting is hingedly coupled to the upper portion of the box 3.

Then, water is supplied by setting the minimum water level (Hm) and the water level (H level) and the water supply error limit time (tm), and if the water level is not reached during the water supply error limit time (tm), the current water level is Judging whether the minimum water level (Hm) has been reached, and if the minimum water level is not reached, the water supply error is displayed and terminated. To memory.

When the water supply is completed, proceed with washing, draining and intermittent dehydration, and compensates the memorized water supply time to refill water for the rinsing stroke until the water supply time is compensated, and the water supply level is one level below the set water level If it does not reach the determined water supply time, the water supply is extended for a certain time from the memorized water supply time. If the water supply time is not reached, the water supply error is displayed and terminated. And exit.

In the present invention thus constructed, as shown in FIGS. 3 to 6, first, the desired water level (H level) and minimum water level (Hm), water supply error limit time (tm) are set, and all conditions are initialized. (1S) Water supply is started. At this time, water is supplied with the new water purification function and ozone generating function turned on.

Then, the water supply time t ₁ is counted (2S), the current water level is compared with the set water level (3S), and the counted water supply time and the water supply error limit time tm are compared and controlled (4S).

That is, when the current water level is above the set water level (H water level ≤ H), the water supply is completed (5S), and when the current water level is lower than the set water level (H water level> H), until the water supply error time limit (tm) is reached. If the water supply is not completed even after the limited water supply time (tm), check whether the current water supply level is above the minimum water supply level (6S) .If the water supply level is below the minimum water supply level (Hm> H), the water supply error is displayed and finished. (7S)

And, if the minimum water level or higher (Hm≤H) when the water supply continues until a water level is set in this way water supply error threshold time (tm) past the water supply is complete, the memory haedunda the water supply time (t _i) at that time (8S).

When the water supply is completed (5S), the water supply is stopped and at the same time the water and ozone generating function is turned off, washing and draining intermittent dehydration (9S) (9S), and the water is supplied again to proceed with the rinsing cycle. At the same time, the water supply time is counted while operating the purified water and ozone generating function (10S).

Here, if a memory to compensate for the water supply time to an arbitrary value (11S), compensation method is m minute filling time (t _{i) i} ≤l ≤t min, t _k = t _i -x min, n min ≤t _{If i ≤} m, t _k = t _i -y minutes and if t _{i ≤} n, t _k = t _i -z minutes (l>m> n, x>y> z).

In other words, when a 50-minute filling time (t _i) as one example ≤t _i ≤60 minutes t _k = t _i -10 min, 40 min ≤t _i ≤50 minutes if t _k = t _i -7 min, t _i ≤ 40 minutes, t _k = t _1i -5 minutes to compensate.

Using the compensated water supply time t _{k as} the reference value at the time of rewatering in the rinsing stroke, the water supply is continued until the water supply time t becomes more than the compensated water supply time t _k (12S), and the water supply time When (t) is equal to or greater than the compensated water supply time t _k , the water level is sensed, and it is checked whether or not the water level is reached one level lower than the set water level (13S).

If the current water level reaches one level lower than the set water level, complete the water supply, turn off the purified water and ozone generation function (14S), and proceed to the rinse cycle according to the selected number of times to drain and dehydrate to finish the washing. (15S).

And, if the current water level is less than one level lower than the set water level, the water supply is continuously supplied for an additional time (a minute) by adding a predetermined time (a minute) to the stored water supply time t _i (16S). The water is continuously supplied so that the current level reaches the low level, and if it does not reach the next level, the water supply error is displayed and terminated (17S).

As described above, the present invention is to measure the water supply time during washing in the region of long water supply time, such as low pressure high ground with a fully automatic washing machine to compensate for the water supply error and delayed water supply time during rinsing administration, thereby preventing the occurrence of water supply error It is a very useful invention that greatly improves the efficiency and reliability of the product because it can greatly reduce the overall washing time by performing a smooth water supply.
