The present invention relates to an ozone sterilizing washing machine which can be washed while sterilizing laundry using ozone water, and in particular, by increasing the concentration of ozone water to improve sterilization effect, and mixing the gaseous ozone with the wash water, the remaining ozone gas is used as a catalyst. The present invention relates to an ozone sterilizing washing machine that decomposes into clean air and releases it into the atmosphere.

1 shows a conventional ozone sterilizing washing machine, referring to the conventional ozone sterilizing washing machine, a washing tank 1, an agitator 2 for mixing water and laundry in the washing tank 1, and the agitator 2 ), A water supply port 4 for supplying water in the washing tank 1, a drain port 5 for draining the water supplied water, and a water drain path of the water drained to the drain port 5. To drain the water coming out of the drain valve (6), the overflow drain port (7) in the washing tank (1), the drain valve (6) and the overflow drain port (7). A hose (8), a gas-liquid mixer (9) for mixing and supplying washing water and ozone gas to the water inlet (4), a water supply valve (10) for supplying the washing water to the gas-liquid mixer (9), and the gas-liquid A circulation valve 11 for controlling a circulation path for increasing the concentration of ozone water passing through the mixer 9, and A circulation pump 12 for circulating ozone water passing through the circulation valve 11, a check valve 13 for controlling a supply path of ozone gas supplied to the gas-liquid mixer 9, and ozone to the check valve 13. An ozone generator 14 for generating and supplying a gas, a negative pressure switch 15 for supplying air to the ozone generator 14, and a gas for filtering the air in the atmosphere and supplying the negative pressure switch 15 to the negative pressure switch 15. It is comprised with the filter 16, and is a washing machine which sterilizes laundry using ozone water.

2 is a view showing the configuration of the gas-liquid mixer 9, the water supply guide 17 connected to the water supply valve 10 and the circulation valve 11 side, and the drainage guide 18 connected to the water supply port 4 side. It is connected to both ends of the gas-liquid mixer 9, a water inlet 9A is formed on the water supply guide 17 side, and a water drain 9B is formed on the drain guide 9B side, while maintaining the diameter of 9A9B, The gas inlet 9C into which ozone gas flows is formed in the structure, and it is a device which mixes gas and a liquid using Bernoulli theorem.

The operation of the conventional ozone sterilizing washing machine configured as described above is as follows.

When the washing machine is turned on and water is supplied, the water supply valve 10 is turned on while the drain valve 6 is turned off, and the water is washed through the water supply valve 10, the gas-liquid mixer 9, and the water inlet 4. (1) The water is supplied to the inside, in the case of normal washing (when not washing the ozone water), the circulation valve 11 is turned off, the circulation pump 12 does not operate, and the ozone generator 14 also does not operate.

However, when ozone washing is desired, the ozone generator 14 operates, and the ozone generator 14 receives ozone from the air filtered through the gas filter 16 through the negative pressure switch 15 to generate ozone. The generated ozone gas is supplied to the gas-liquid mixer 9 through the check valve 13.

The gas-liquid mixer 9 is a device for mixing gas (ozone gas) and liquid (washed water) using Bernoulli's theorem as shown in FIG. 2, wherein the diameter of the inlet 9A is smaller than that of the drain 9B. Therefore, a negative pressure is formed at the drain port 9B side, and the gas introduced into the gas inlet 9C is mixed with the wash water introduced into the water inlet 9A through the water supply guide 17, and ozone water is washed through the drain guide 18. (1) It is supplied with water.

When the water supply proceeds and maintains a constant water level, the water supply valve 10 is turned off to stop the water supply. Since the ozone water supplied into the washing tank 1 is low in concentration, the ozone water is subjected to the following ozone water concentration process to increase the ozone concentration. .

That is, the circulation valve 10 is turned on so that the circulation pump 12 operates so that the ozone water in the washing tank 1 discharges the drain 5, the circulation pump 12, the circulation valve 11, the gas-liquid mixer 9, and the water supply port. (4) The ozone concentration increases each time the gas-liquid mixer 9 passes through the washing tank 1.

As described above, after the ozone water is produced and the concentration is increased, the agitator 2 is driven by the driving of the motor 3, and various processes such as washing, rinsing, and dehydration are performed. And the drain hose (8).

However, the conventional ozone sterilizing washing machine as described above has the following problems.

Ozone gas, due to its characteristics, requires a certain time to dissolve in water in the gas state, and the time depends on the shape of the ozone gas when it comes in contact with water, and the smaller the particle size is, the more advantageous. The conventional ozone sterilizing washing machine does not have sufficient mixing time because the ozone water mixed in the gas-liquid mixer 9 is directly supplied into the washing tank 1, and thus ozone gas that is not mixed with water is supplied into the washing tank 1. Therefore, the ozone gas is directly released into the atmosphere to act as a harmful component to the human body, there is a problem that the ozone water circulation process must be further proceeded to increase the concentration of ozone water.

The present invention is to mix the ozone gas and water to pass through the dissolution tube to extend the mixing time of the ozone gas and water in the step before the water supply to the washing tank through the water inlet, the concentration of ozone water is not dissolved through the dissolution tube The ozone gas is separated through the gas-liquid separator to separate the ozone gas from the ozone water, and the separated ozone water is supplied into the washing tank, and the separated ozone gas is made into clean air through a catalyst and released into the atmosphere. Of course, an object of the present invention is to provide an ozone sterilizing washing machine capable of preventing the release of undissolved ozone gas.

Figure 3 shows the ozone sterilizing washing machine configuration of the present invention for achieving the above object.

Referring to FIG. 3, the ozone sterilizing washing machine of the present invention includes a washing tank 21, a stirrer 22 for mixing water and laundry in the washing tank 21, and a motor 23 for driving the stirrer 22. And a clutch 24 for controlling the power of the motor 23 to be transmitted to the stirrer 22, a drain valve 25 and a drain hose 26 for draining the water in the washing tank 21, and washing A water supply valve 27 for supplying and controlling water, a gas-liquid mixer 28 for mixing ozone gas with water passing through the water supply valve 27, an ozone generator 29 for generating ozone gas, and the ozone generator ( 29) a dehumidifier (30) for removing moisture from air in the air and supplying air, an air valve (31) for supplying and controlling the ozone gas generated from the ozone generator (29) to the gas-liquid mixer (28), When passing through the ozone water for a time sufficient to dissolve the ozone gas mixed in the gas-liquid mixer 28 in water The separation pipe 32, the ozone water passed through the dissolution pipe 32 and the remaining ozone gas is separated, and the ozone water is supplied to the washing tank 21, the gas-liquid separator 33 for separating and discharging the ozone gas, and the gas liquid A catalyst filter 34 for purifying ozone gas separated from the separator 33 and releasing it into the atmosphere, and a detergent container 35 for mixing detergent with ozone water separated from the gas-liquid separator 33 and supplying the detergent to the washing tank 21. It is composed.

Operation of the ozone sterilizing washing machine of the present invention configured as described above will be described below with reference to FIG.

When the washing machine is turned on in order to wash the ozone and the water supply proceeds, the water supply valve 27 is turned on, the ozone generator 29 is operated, and the air valve 31 is turned on.

Water passing through the water supply valve 27 is supplied to the gas-liquid mixer 28, and the ozone generator 29 receives ozone from the clean air dehumidified through the dehumidifier 30 to generate ozone, and the generated ozone gas is air. It is supplied to the gas-liquid mixer 28 via the valve 31.

The gas-liquid mixer 28 is a mixing equipment of gas (ozone gas) and liquid (water) using Bernoulli's theorem. The gas-liquid mixer 28 mixes ozone gas supplied through the air valve 31 and water supplied through the water supply valve 27. Ozone water is produced, and this ozone water is supplied to the dissolution pipe 32.

The dissolution tube 32 is formed as a spiral tube of a close form as an example.

Therefore, while passing through this spiral dissolution tube 32, the ozone gas is dissolved with sufficient time to dissolve in water to produce a high concentration of ozone water, which is supplied to the gas-liquid separator 33.

The gas liquid separator 33 separates gas and liquid.

That is, the ozone gas and the ozone water which are not dissolved in water while passing through the dissolution pipe 32 are separated from each other. The liquid and the gas are completely separated by using the difference in the specific gravity of the ozone gas as the liquid and the ozone gas as the gas.

As the separated ozone gas is released into the atmosphere as it is harmful to the human body, the ozone gas is converted into clean air through the catalytic filter 34 and released into the atmosphere, and the separated ozone water passes through the detergent container 35 together with the detergent. It is supplied into the washing tank 21.

When the supply of ozone water into the washing tank 21 is completed, the washing motor 23 is driven to drive the stirrer 22 through the clutch 24, and the overall process of washing, rinsing, and dehydration is performed, and the drain valve 25 ) Is properly turned on to discharge the contaminated water in the washing tank 21 to the drain hose 26.

4 shows an embodiment of the gas-liquid mixer 28.

The gas-liquid mixer 28 satisfies the relationship between the inlet 28A through which the water is supplied and the outlet 28B through which the ozone gas is mixed with the water have a diameter of 28A28B, and ozone gas is introduced at a position past the inlet 28A. An air guide 28C is mounted.

Inside the air guide 28C, there is a gas inlet 28D, which is a path through which ozone gas is supplied, and a ball 28E for opening and closing the gas inlet 28D by a pressure difference is provided. A ball guide 28F on which 28E is seated is configured in a direction opposite to the gas inlet 28D.

Referring to the operation of the gas-liquid mixer 28 configured as described above, when ozone gas flows into the gas inlet 28D, the ball 28E is pushed toward the ball guide 28F as shown in FIG. 5A, and the gas-liquid mixer When water supply of (28) is stopped, as shown in (b), the ball 28E closes the gas inlet 28E to prevent the backflow of water to the ozone generator 29 side.

That is, due to the difference between the gas pressure and the hydraulic pressure, the ball 28E operates to introduce ozone gas into the gas inlet 28D, and the introduced ozone gas is supplied into the gas-liquid mixer 28 to the water supplied to the inlet 28A. The mixed ozone water is discharged to the outlet 28B, and when the water supply is stopped, the ball 28E closes the gas inlet 28D by water pressure to prevent the water from entering the ozone generator 29 side. will be.

6 (a) and 6 (b) show the structure and operation of the first embodiment of the gas-liquid separator 33 of the present invention described above.

As shown in FIG. 6, the gas-liquid separator 33 of the present invention has an inlet 33A through which ozone gas and ozone water are introduced, and an outlet 33B through which the introduced ozone gas and ozone water are separated by gas-liquid separation and discharged. The gas inflow prevention guide 33C which prevents outflow of ozone gas to the exit 33B side when the water level line is formed at low water pressure is formed.

The ozone water and undissolved ozone gas supplied from the gas-liquid separator 33 having the above-described configuration to the inlet 33A are naturally separated by the difference in the specific gravity of the gaseous ozone gas and the liquid ozone water, and especially at high water pressure. As shown in Fig. 6A, a water level line is formed and discharged to the catalyst filter 34 side of ozone gas, and the ozone water flows out to the outlet 33B side and is supplied to the washing tank.

At the time of low water pressure, the height of the gas inflow prevention guide 33C is formed as high as a predetermined height H than the upper end of the aperture of the outlet 33B as shown in FIG. 6 (b). The discharge to the outlet 33B side can be discharged beyond 33C), but the discharge to the outlet 33B side is supported.

7 (a) and 7 (b) are views showing the configuration and operation of the second embodiment of the gas-liquid separator 33 of the present invention.

As shown in FIG. 7, the gas-liquid separator 33 of the present invention is located in a direction in which the inlet 33A and the outlet 33B face each other, and separates ozone water and undissolved ozone gas supplied to the inlet 33A from each other. Thus, a separator 33E having a plurality of ozone water passage holes 33D through which only ozone water passes is provided between the inlet 33A and the outlet 33B.

In the gas-liquid separator 33 having such a configuration, the ozone water and the undissolved ozone gas introduced into the inlet 33A strike the separation plate 33E, so that the ozone gas rises upward and is discharged to the catalyst filter 34, and the ozone water is the separation plate. It passes through the ozone water passage hole 33D formed below the 33E and is discharged to the outlet 33B side. In this embodiment, the ozone gas is prevented from being discharged to the outlet 33B by the ozone gas inflow guide 33C. do.

As described above, according to the present invention, since the concentration of the formed ozone water mixed in the gas-liquid mixer 28 is sufficiently dissolved through the dissolution pipe 32, the ozone concentration can be increased. Since only air, such as oxygen and nitrogen, separated from the gas-liquid separator 33 and passed through the catalyst filter 34 is discharged into the atmosphere, it is possible to prevent harmful environments caused by ozone, and does not affect the environment. There is an effect that the circulating process for this can be excluded.
