Hereinafter, with reference to the drawings will be outlined the home sterilizing apparatus disclosed herein. The household sterilization washing apparatus with reference to the drawings is an electrolysis unit 200 which increases the amount of dissolved gas while generating sterilization ions by electrolyzing water in the accommodating part 100 and the accommodating part 100 in which water and washing objects are accommodated, The control unit 400 controls the operation of the ultrasonic generator 300 and the electrolysis unit 200 and the ultrasonic generator 300 to reduce the amount of dissolved gas while generating ultrasonic waves into the receiving unit 100, the ultrasonic cleaning proceeds. Including, the control unit 400 includes a concentration maintaining process (S100) for controlling the concentration of the dissolved gas by stopping at least one operation of the electrolysis unit 200 or the ultrasonic generator 300. Of course, you can get it working again after stopping.

The stopping time of the electrolysis unit 200 or the ultrasonic generator 300 of the dissolved gas holding process (S100) is at least 20% of each time the electrolysis unit 200 or the ultrasonic generator 300 operates. That is 200% of the time.

The controller 400 may optionally further include an environmental composition process S200 for increasing the concentration of dissolved gas by operating the electrolysis unit 200 before the dissolved gas maintenance process S100.

Receiving unit 100 is composed of a conventional container that can hold water. Receiving unit 100 may be composed of a non-conductive material. On the other hand, it may further include a channel plate formed with one or more holes to be inserted into the container. Receptacle 100 is to accommodate the water and the object to be cleaned. Cleaning objects contained in the receiving part 100 are fruits and vegetables, grains, tableware, and the like.

The electrolysis unit 200 is composed of a conventional electrolysis device composed of an electrode. The electrolysis unit 200 is connected to the control unit 400 to be described below. The electrolysis unit 200 is installed inside the accommodation unit 100. The electrolysis unit 200 may be installed on the inner bottom of the accommodation unit 100. The electrolysis unit 200 electrolyzes the water contained in the accommodation unit 100 to generate hydroxyl groups by chemical reaction of oxygen-based active species including a large amount of hydroxide ions. The hydroxyl group can sterilize various bacteria and viruses. Meanwhile, the electrolysis unit 200 separates water into oxygen and hydrogen to electrolyze the water inside to generate gas (gas) such as oxygen or hydrogen while generating germicidal ions, and is discharged to the outside while floating on the water surface. In addition, some gases may dissolve in water to increase the concentration of dissolved gases. Furthermore, the electrolysis unit 200 may further increase the concentration of dissolved gas by lowering the mass of water by electrolyzing the water.

The ultrasonic wave generator 300 is composed of a conventional ultrasonic apparatus. The ultrasonic wave generation unit 300 is installed on the inner surface of the accommodation unit 100 to provide ultrasonic waves into the accommodation unit 100. As another example, the ultrasound generating unit 300 may be provided with a receiving unit 100 outside. The ultrasonic wave generator 300 induces a cavitation phenomenon through ultrasonic waves to perform ultrasonic cleaning. On the other hand, the gas or gas component dissolved in the solution is called dissolved gas, the dissolved gas is moved to the water surface by the cavitation phenomenon by the ultrasonic generator 300 can lower the concentration of the dissolved gas.

The control unit 400 is composed of a conventional PCB board or computer. The controller 400 is connected to the electrolysis unit 200 and the ultrasonic wave generation unit 300 to control the operation. The control unit 400 according to an embodiment includes a concentration maintaining process (S100) of controlling at least one operation of the electrolytic unit 200 or the ultrasonic wave generator 300 to control the concentration of the dissolved gas. Concentration maintenance process (S100) is to adjust the concentration of the gas (gas) dissolved in water or fluid and liquid accommodated in the receiving portion 100, that is, the amount of dissolved gas.

In general, ultrasonic cleaning is performed to clean a cleaning object by cavitation by ultrasonic waves. Cavitation is a phenomenon in which a cavity is formed and destroyed in a fluid according to a change in pressure applied to the fluid through ultrasonic vibration. Say In the process of generating the cavity, when the pressure of the fluid is lower than the saturated vapor pressure by the ultrasonic waves applied to the fluid, a part of the fluid is vaporized to generate a cavity in the fluid. Thereafter, the generated cavity is exploded by applying a positive pressure above the surface tension of the fluid to the cavity by the ultrasonic waves applied to the fluid.

On the other hand, when the amount of dissolved gas in the fluid increases the concentration of dissolved gas dissolved gas may serve to promote the cavitation phenomenon. In this case, when the dissolved gas amount is less than the dissolved saturation degree, which is the solubility limit of the gas in the fluid, the cavitation may be increased to improve the washing power utilizing the cavitation phenomenon. However, when the amount of dissolved gas is higher than the dissolved saturation degree, the dissolved gas existing above the dissolved saturation degree is changed into gas bubbles, and the dissolved gas converted into gas bubbles acts as an allowance to inhibit the cavitation phenomenon by absorbing ultrasonic waves. Therefore, the cavitation phenomenon is accelerated when ultrasonic wave is applied to the fluid with dissolved gas below the dissolved gas compared with the case where ultrasonic wave is applied to the fluid from which the dissolved gas is removed to cause the cavitation phenomenon. When ultrasonic waves are applied to the fluid in which the dissolved gas is present, it can be understood that the gas bubbles formed in the fluid by the bubbles having the dissolved saturation degree absorb the ultrasonic waves, thereby reducing the cavitation phenomenon.

Accordingly, the concentration of the dissolved gas may be maintained at an appropriate level through the concentration maintaining process (S100) of the controller 400 to maintain the washing efficiency at an appropriate level. When the concentration of dissolved gas is increased by the gas (gas) generated through the electrolysis unit 200, the operation of the electrolysis unit 200 is stopped and only the ultrasonic wave generation unit 300 is operated, so that the washing efficiency is lowered. To prevent them. In addition, the concentration of the dissolved gas may be lowered to allow the dissolved gas to be discharged out of the water through cavitation by ultrasonic waves. That is, by controlling the operation of the electrolysis unit 200 and the ultrasonic wave generation unit 300 through the concentration maintaining process (S100) is configured to complement each other to maintain an appropriate level of cleaning efficiency. Further sterilization power can also be maintained at an appropriate level.

Experiment results disclosed in FIG. 2 are provided with the electrolysis unit 300 and the accommodation unit 100 under the same conditions as the ultrasonic wave generation unit 200 under the same conditions, and the same weight in the state in which the same water is filled in the accommodation unit 100. After spreading the aluminum foil in water, the results of the ultrasonic and electrolysis by conditions are shown. As shown in the experimental results shown in FIG. 2, the weight of the aluminum foil reduced by only operating the ultrasonic wave was 0.0076g, while the weight of the aluminum foil reduced by simultaneously operating the ultrasonic wave and the electrolysis was confirmed to be high as 0.0168g. In particular, it is confirmed that the weight of the aluminum foil is reduced to 0.0409 g when the ultrasonic waves are continuously operated and the electrolysis is interrupted. That is, rather than simply operating the same ultrasonic and electrolysis, it can be seen that by selectively stopping the ultrasonic wave generation unit 300 or the electrolysis unit 200 can be expected to increase the cleaning efficiency.

This concentration maintenance process (S100) can maintain the amount of dissolved gas of the water used for washing, it can be used for a long time without grinding the water used for a long time electrolysis. By maintaining the dissolved gas concentration by the electrolysis unit 200 through the dissolved gas holding process (S100), and by lowering the concentration of the dissolved gas by the ultrasonic generator 300, the concentration of the dissolved gas is always constant. Is maintained so that there is an effect that can maintain a constant cavitation cleaning efficiency by the ultrasonic wave.

For example, the time at which the electrolysis unit 200 or the ultrasonic generator 300 of the dissolved gas holding process S100 is stopped is at least one of each time the electrolysis unit 200 or the ultrasonic generator 300 operates. And from 20% to 200% of time.

The control unit 400 according to another embodiment further operates the electrolysis unit 200 prior to the above-described dissolved gas maintenance process S100 to further increase the concentration of the dissolved gas in advance to create an environmental process S200. Include. Environmental composition process (S200) is to increase the amount of dissolved gas dissolved in the water in the natural state so that the cavitation phenomenon can be easily expressed by the ultrasonic wave of the ultrasonic generator 300 which is operated for the first time. In the environmental composition process (S200), the ultrasonic cleaning is performed at least in a state where the amount of dissolved gas is filled up to the dissolved saturation degree, so that the variation in the efficiency of ultrasonic cleaning can be narrowed, thereby making the ultrasonic cleaning quality even.

From the above, various embodiments of the present disclosure have been described for purposes of illustration, and it will be understood that various modifications are possible without departing from the scope and spirit of the present disclosure. And the various embodiments disclosed are not intended to limit the present disclosure, the true spirit and scope will be presented from the following claims.
