BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 attached herewith is a view showing the entirety of the household sterilizing and cleaning apparatus disclosed in the present specification. FIG. 2 is a graph showing an experiment result of measuring cleaning efficiency according to selective operation of an ultrasonic wave and electrolytic apparatus under the same condition. FIG.

Hereinafter, the household sterilizing and cleaning apparatus disclosed in this specification will be described with reference to the drawings. The household sterilizing and cleaning apparatus according to the present invention includes an electrolytic unit 200 for electrolyzing water in a receptacle 100 for accommodating water and a subject to be cleaned and for increasing the amount of dissolved gas while generating sterilizing ions, A controller 400 for controlling the operation of the ultrasonic generator 300 and the electrolysis unit 200 and the ultrasonic generator 300 to generate ultrasonic waves into the receptacle 100 and to reduce the amount of dissolved gas while performing ultrasonic cleaning; The control unit 400 includes a concentration maintaining process S100 for stopping at least one of the electrolysis unit 200 and the ultrasonic generator 300 to control the concentration of the dissolved gas. Of course, it can work again after stopping.

The stopping time of the electrolysis unit 200 or the ultrasonic generator 300 in the dissolved gas maintaining process S100 may be at least 20% or more of each time of the operation of the electrolytic unit 200 or the ultrasonic generator 300 200% of the time.

The control unit 400 may further include an environment creating step S200 for increasing the concentration of the dissolved gas by operating the electrolysis unit 200 before the dissolved gas holding step S100

The receptacle 100 is constructed of a conventional container capable of storing water. The receiving portion 100 may be made of a nonconductive material. On the other hand, it may further include a mouthpiece having at least one hole formed therein. The receptacle 100 accommodates water and contains objects to be cleaned. The objects to be cleaned in the receptacle 100 are fruits, vegetables, cereals, tableware, and the like.

The electrolytic unit 200 is constituted by a conventional electrolytic apparatus composed of electrodes. The electrolysis unit 200 is connected to the control unit 400, which will be described below. The electrolytic part 200 is installed inside the housing part 100. The electrolytic part 200 may be installed on the inner bottom of the receiving part 100. The electrolysis unit 200 electrolyzes the water contained in the storage unit 100 to generate a hydroxyl group by a chemical reaction of oxygen-containing active species including a large amount of hydroxide ions. The hydroxyl group can sterilize various bacteria and viruses. On the other hand, the electrolytic unit 200 separates water into oxygen and hydrogen, and electrolyzes the water in the electrolytic unit 200 to generate gas (gas) such as oxygen or hydrogen while generating sterilizing ions, , Some of the gas can be dissolved in water to increase the concentration of dissolved gas. Further, the electrolysis unit 200 can electrolyze water to lower the mass of water, thereby further increasing the concentration of dissolved gas.

The ultrasonic wave generator 300 is constituted by a conventional ultrasonic wave device. The ultrasonic wave generator 300 is installed on the inner surface of the receiver 100 to provide ultrasonic waves into the receiver 100. The ultrasonic wave generator 300 may be installed outside the receiver 100 as another example. The ultrasonic wave generator 300 induces a cavitation phenomenon through an ultrasonic wave to perform ultrasonic cleaning. On the other hand, the gas or gas component dissolved in the solution is referred to as dissolved gas. The cavitation phenomenon caused by the ultrasonic wave generator 300 moves the dissolved gas above the water surface to lower the concentration of dissolved gas.

The controller 400 includes a conventional PCB substrate or a computer. The control unit 400 is connected to the electrolysis unit 200 and the ultrasonic generator 300 to control the operation. The control unit 400 according to an exemplary embodiment includes a concentration maintaining process S100 for stopping at least one of the operation of the electrolysis unit 200 and the ultrasonic generator 300 to control the concentration of the dissolved gas. The concentration holding process S100 is to adjust the concentration of the dissolved gas or water or fluid and the gas (gas) contained in the container 100, that is, the amount of dissolved gas.

Conventional ultrasonic cleaning is to clean the object to be cleaned by cavitation phenomenon by ultrasonic waves. Cavitation phenomenon is a phenomenon in which a cavity is created and destroyed in a fluid according to a change in pressure applied to the fluid through ultrasonic vibration . When the fluid pressure is lower than the saturated vapor pressure due to the ultrasonic waves applied to the fluid, a part of the fluid is vaporized and a cavity is formed in the fluid. Thereafter, the generated cavity explodes as the positive pressure higher than the surface tension of the fluid is applied to the cavity due to the ultrasonic waves applied to the fluid and contracted.

On the other hand, when the amount of dissolved gas in the fluid increases and the concentration of dissolved gas increases, the dissolved gas can play a role of promoting the cavitation phenomenon. In this case, when the dissolved gas amount is equal to or lower than the solubility saturation which is the solubility limit of the gas relative to the fluid, the cavitation can be increased to improve the cleaning ability utilizing the cavitation phenomenon. However, when the amount of dissolved gas is higher than the saturation of dissolved gas, the dissolved gas existing above the dissolved saturation is converted into gas bubbles, and the dissolved gas changed into gas bubbles absorbs ultrasound and acts as an adversary to inhibit the cavitation phenomenon. Therefore, cavitation phenomenon is accelerated when ultrasonic waves are applied to a fluid having dissolved gas below the dissolved gas saturation degree of the dissolved gas compared with the case where ultrasonic waves are applied to the fluid from which the dissolved gas has been removed to cause the cavitation phenomenon. However, When the ultrasonic wave is applied to the fluid in which the dissolved gas exists, it is understood that the gas bubbles formed in the fluid by the bubbles having the degree of solubility saturate absorb the ultrasonic waves and the cavitation phenomenon deteriorates.

Accordingly, the amount of dissolved gas can be maintained at an appropriate level through the concentration maintaining process (S100) of the controller 400, thereby maintaining the cleaning efficiency at an appropriate level. When the concentration of the dissolved gas is raised by the gas (gas) generated through the electrolysis unit 200, the operation of the electrolysis unit 200 is stopped and only the ultrasonic generator 300 is operated, ≪ / RTI > The concentration of the dissolved gas can be lowered so that the dissolved gas is discharged out of the water surface through the cavitation phenomenon by the ultrasonic wave. That is, the operation of the electrolysis unit 200 and the ultrasonic generator 300 is controlled through the concentration maintaining process S100 so that the cleaning efficiency can be complemented to maintain an appropriate level. Furthermore, the sterilizing power can be maintained at an appropriate level.

2, the electrolysis unit 300 and the accommodating unit 100 are provided with the same conditions as those of the ultrasonic generator 200 under the same conditions. When the same water is filled in the accommodating unit 100, After spreading the aluminum foil in water, it shows the result of running ultrasonic wave and electrolysis conditionally. As shown in the experimental results shown in FIG. 2, it is confirmed that the weight of the aluminum foil decreased by operating only the ultrasonic wave was 0.0076g, while the weight of the aluminum foil decreased by ultrasonic wave and electrolysis simultaneously was as 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 wave is continuously operated and the electrolysis is interrupted. That is, it can be seen that the increase in the cleaning efficiency can be expected by selectively stopping the ultrasonic wave generator 300 or the electrolysis unit 200, rather than simply operating the ultrasonic wave and the electrolysis in the same manner.

This concentration holding process (S100) can maintain the dissolved gas amount of the water used for washing at an appropriate level, so that it can be used for a long time without splitting the electrolyzed water for a long time. The concentration of the dissolved gas by the electrolysis unit 200 is increased through the dissolved gas holding process S100 and the concentration of the dissolved gas is lowered by the ultrasonic wave generator 300 so that the concentration of the dissolved gas is always constant So that the cavitation cleaning efficiency by the ultrasonic wave can be maintained constant.

For example, the stop time of the electrolysis unit 200 or the ultrasonic generator 300 in the dissolved gas holding process S100 may be at least the time during which the electrolysis unit 200 or the ultrasonic generator 300 operates 20% to 200% of the time.

The control unit 400 according to another embodiment may further include an environmental composition step S200 for increasing the concentration of the dissolved gas by activating the electrolysis unit 200 before the dissolved gas maintaining process S100 described above . The environmental composition process (S200) increases the amount of dissolved gas dissolved in the water in the natural state so that the cavitation phenomenon can be easily manifested by the ultrasonic wave of the ultrasonic generator 300 which is operated first. In this environment forming process (S200), the fluctuation of the efficiency of ultrasonic cleaning can be narrowed by making at least the ultrasonic cleaning from the state where the dissolved gas amount is filled up to the dissolved saturation degree, so that the ultrasonic cleaning quality can be made even.

From the foregoing it will be appreciated that various embodiments of the present disclosure have been described for purposes of illustration and that there are many possible variations without departing from the scope and spirit of this disclosure. And that the various embodiments disclosed are not to be construed as limiting the scope of the disclosed subject matter, but true ideas and scope will be set forth in the following claims.
