It is preferable that the upper cover 11 has a structure capable of ensuring water tightness in order to prevent the spinal cord from flowing out of the washing tub 10 due to the flow of the washing water by the washing water spouting means described later.

Although not shown in the drawing, the lid 11 is preferably provided with a closure means for ensuring a closed state of the lid 11 during a cleaning operation.

Other details of the upper cover will be described later.

Further, a discharge port 12 for discharging suspended particles is further formed on the upper portion of the washing tank 10.

The discharge port 12 may be provided on one side of the upper portion of the washing tub 10, or may be formed on the upper side of the washing tub 10 depending on the shape of the washing tub.

The discharge port (12) serves to discharge foam, oil, or other foreign matter floating on the wash water when the wash object (C) is washed, together with the wash water.

That is, bubbles generated in the course of cleaning the cleaning object C by the cleaning apparatus according to the present invention, oil or foreign matter separated and separated from the object C to be cleaned float up to the top of the cleaning water, Flows to the outside of the washing tank by the spraying means and is automatically discharged and discharged through the discharge port (12)

It is not necessary to remove or collect the foreign substances generated during washing through a separate operation, and the degree of contamination of the washing water in the washing tub 10 during washing is reduced, and the sewage drained when the washing water is drained is blocked by the foreign substance none.

Further, the discharge port (12) is further provided with a purifying means, such as a filtering net, for filtering foreign substances adhered to the cleaning object (C), so that the clean water discharged together with the foreign matter is purified to discharge only clean clean water to the drain. Can be reduced.

The bubble forming means can be made in various ways,

As shown in FIG. 1, the bubble forming means includes a pressurizing pump 31 and a bubble nozzle 32, and may be connected to a second pipe 33.

The bubble forming means is configured to discharge the washing water through the pressurizing pump 31 and to form microbubbles through the structural design of the bubble nozzle 32 or to prevent the microbubbles from being formed between the pressurizing pump 31 and the bubble nozzle 32 A bubble forming member (not shown) may be provided in the washing water to discharge microbubbles into the discharged washing water.

The color of micro bubbles is suddenly fine bubbles splashing continuously, and it shrinks and disappears in the water, and at the same time it rises at a very slow speed, and the shock wave including the ultrasonic wave of 40Khz has a speed of 400 km per hour, It provides various effects while generating high temperature (about 5,500 degrees).

The microbubbles are able to maximize the cleaning effect by removing various kinds of agricultural chemicals contained in fruits and vegetables, foreign materials such as tableware and clothes by the shock wave including sterilization effect and strong ultrasonic waves.

Preferably, the bubble forming means forms and discharges bubbles by using the washing water of the washing tank 10.

To this end, the bubble forming means of the present invention includes a suction pipe 34 for sucking the washing water of the washing tank 10 and supplying the washing water to the pressurizing pump 31, a water supply pipe 34 for supplying the washing water from the washing water supply source to the pressure pump 31 And piping,

The pressurizing pump 31 may further include a valve member (not shown) for selectively introducing the wash water supplied from the suction pipe or the wash water supply source.

The suction pipe (34) forms a suction port on one side of the washing tub (10) to suck the washing water during washing.

The washing water in the washing tank 10 is sucked into the bubbles to reduce the burden of an increase in the cleaning cost due to the use of water and the contaminated washing water is circulated so as to be floated together with the microbubbles to be discharged through the discharge port 12 So that the degree of contamination of the cleaning tank 10 can be reduced.

Then, the circulation of the washing water through the suction pipe 34 allows the washing water to be continuously sprayed by the washing water spraying means.

That is, as described above, the washing water is discharged through the discharge port 12, so that the washing tub 10 can maintain a constant water level. However, when the washing water is continuously discharged, the discharge capacity of the discharge port 12 may be exceeded, The water level in the water tank 10 may become difficult to adjust.

However, according to the present invention, the above-described cleaning water is sucked into the bubbles to aid in the above-described function of adjusting the level of the discharge port, and foreign matter contained in the cleaning water is floated together with the microbubbles to be discharged to the discharge unit. .

Furthermore, in the washing machine according to the present invention, it is also possible that the bubble forming means receives the washing water from the main pipe directly connected to the washing water supply source to form the micro bubble.

More preferably, the water level control in the cleaning tank 10 and the degree of contamination of the washing water are adjusted by making the supply of the washing water to the bubble forming means described above selectively from the washing water or the washing water supply source in the washing tank 10.

To this end, the present invention is characterized in that the pressurizing pump is provided with a valve member capable of selecting wash water, and a water level sensor (not shown) is provided on one side of the upper side and the lower side of the wash tank 10, Or,

And a microcomputer (not shown) capable of controlling the time, so that the supply of wash water to the bubble forming means is selectively performed according to the type and amount of the cleaning object C, Or the wash water selective supply time can be sufficiently predicted and reproduced by those skilled in the art.

The environmentally-friendly microbubble washing machine according to the present invention includes washing water ejecting means for washing the object to be cleaned by the washing water which flows by discharging the washing water supplied from the washing water supply source.

It goes without saying that the wash water supply source can be utilized not only in the conventional commercial water supply but also as a water tank or a separate wash water supply unit provided on the site using the washing machine of the present invention.

The expression of washing the cleaning object C with the flowing wash water means that the wash water is flowed and circulated to wash the flowing object water (running water).

According to the Korea Food and Drug Administration, it is easy to remove foreign substances including fine pesticides such as residual pesticides and viruses by simple washing of the surface smooth fruits, but it is more sensitive than the case of lettuce, , It is possible to ensure a more reliable cleaning force than to wash the flowing water.

As a result of the Korea Food & Drug Administration (KFDA), when the surface was not bent, such as blueberry, 94.5% of the immersion water and 99.6% of the flowing water were cleaned,

In case of irregular surface such as lettuce, it was proved that washing by draining water is cleaner by measuring the washing rate of 45.1% in dipping water washing and 82.8% in flowing water washing,

The present invention can perform secondary washing and sterilization through microbubbles by using the cleaning and blowing means and the bubble forming means described above, thereby making it possible to ensure the washing of the cleaning object C more intensively.

For this purpose, the washing water jetting means includes an upper jet nozzle 24 for jetting water toward the object to be cleaned from the upper part of the washing water surface contained in the washing tank, and a lower jet nozzle 24 provided on the lower surface of the washing bath body for flowing the washing water in the washing tank, And a nozzle (25).

The washing water jetting means includes a first pipe (22) connecting the upper jet nozzle and the lower jet nozzle,

The first pipe is connected to a main pipe (21) connected to a washing water supply source.

The piping has a flow path shape in which the washing water flows into the upper and lower spray nozzles 24 and 25 and is directly sprayed.

A control valve (not shown) may be further provided at the connection between the first pipe 22 and the main pipe 21 to control the supply of the washing water to the upper spray nozzle 24 and the lower spray nozzle 25 In addition,

A typical example of the control valve may be a "T" -shaped valve.

The upper lid 11 is connected to the washing tank through a hinge so as to be opened and closed. The upper lid nozzle is coupled to the lower surface of the upper lid through a fixing part. The upper spray nozzle 24 is connected to the washing water supply source And a first flexible pipe which is flexible.

That is, since the upper spray nozzle 24 is coupled to the lower surface of the upper cover through the fixing portion, the first pipe may be broken due to the opening and closing of the upper cover. Therefore, It is preferable that the first washing water supply part 22a of the second water supply pipe 22 is connected by a flexible pipe.

The flexible pipe may be a general hose made of a synthetic fiber such as rubber or a multi-section folding hose.

The first washing water supply unit 22a may be exposed or embedded in the lower surface of the upper cover.

1, the upper spray nozzle 24 is provided on the lower surface of the upper lid 11 and is formed higher than the wash water level of the washing tank 10,

Or the length of the fixed portion of the upper spray nozzle 24 may be adjusted to allow the upper spray nozzle 24 to be immersed in the wash water when the wash water is full after the upper cover 11 is closed.

When the upper spraying nozzle 24 is submerged in the washing water, the washing water is sprayed in the washing water, so that the washing water flows more strongly.

In addition, a length adjusting means is provided on the fixing part according to the type and amount of the cleaning object, so that the user can adjust the upper cleaning nozzle according to the cleaning environment.

1, the lower spray nozzle 25 is connected to the first pipe 22 connected to the main pipe 21 and is formed in the form of a tube having a plurality of wash water spray holes 25A. have. At this time, the second washing water supply part 22b of the first pipe 22 connecting the control valve and the lower spray nozzle 25 is formed of a pipe fixed to the washing tub body. This is because the second washing water supplying portion 22b is not displaced unlike the first washing water supplying portion 22a.
The lower spray nozzle 25, which is in the form of a tubular body, is provided along the circumference of the lower surface of the washing tub body to discharge washing water.

Although the lower spray nozzle is shown as being exposed toward the lower inner surface of the washing tub 10 for the sake of convenience of explanation, it is preferable that the lower spray nozzle is depressed on the lower surface of the body of the washing tank 10 so that only the spray holes 25A are exposed It is also possible.

The upper spray nozzle 24 may also be formed in the form of a tube like the lower spray nozzle 25.

As shown in FIG. 2, the washing water in the washing tub flows by the pressure of the washing water discharged through the upper spray nozzle and the lower spray nozzle, and vortex or turbulence is induced,

Such vortex or turbulence acts like a flowing water, so that foreign substances and pesticides existing on the surface of the cleaning object C can be cleanly cleaned.

Although not shown in the drawings, the upper and lower spray nozzles 24 and 25 are constituted by propeller type nozzles as needed, and the spray nozzles can be swiveled as the washing water is sprayed from the ends of the propeller type tubular bodies And may be configured to make vortex or turbulent generation intensity stronger.

That is, the jetting nozzles are twisted in a spiral form, or the jetting nozzles are configured to rotate with the pressure of the jetted water discharged from the jetting water jetting hole as a thrust, thereby generating stronger vortices and turbulence, It is also possible to maximize the cleaning action by the water.

Further, the jet nozzle of the propeller type is provided with a separate motor so as to be rotated by the power, and turbulence can be generated by varying the forward and reverse directions in the rotational direction.

The present invention can be designed by introducing a micro bubble forming structure into the pressurizing pump in order to maximize the bubble forming effect of the bubble forming means and enable bubble formation and discharge through simple structure to reduce the manufacturing cost .

3, the pressurizing pump 31 includes an inlet 31A through which the washing water flows, a mixing portion 31B that mixes the microbubbles with the introduced washing water, and a mixing portion 31B that mixes the mixed washing water with the washing tub 10, And a discharging portion 31C for supplying the discharging portion 31C.

The mixing portion 31B includes an impeller 31D having a mixing blade and an air suction pipe 31D adjacent to the inlet 31A and sucking air toward the rotational direction of the impeller 31D And the discharge unit includes a mixing pipe 31C for circulating the purified water mixed with the air by the rotation of the impeller 31E to pressurize the air mixed with the microbubbles to generate microbubbles.

Due to the rotation of the impeller 31E, a vacuum lower than the atmospheric pressure is formed in the mixing portion 31B, so that the outside air is sucked, and the air and the washing water can be mixed.

In the conventional pump, cavitation occurs in the pump when the air is sucked in the liquid because the air intake port is sucked in the direction of the central axis of the impeller. As a result, noise and vibration occur together with the inability to suction the fluid.

The pressurizing pump 31 of the present invention solves the above problem by sucking air in the direction of conveyance of the washing water and the direction of rotation of the impeller 31E and prevents the mixed washing water from flowing through the narrow impeller 31E section after rotation through the impeller 31D And the mixed air is converted into a micro bubble to discharge the washing water mixed with the micro bubble.

The washing water mixed with the microbubbles flows back into the washing tank 10 through the discharge pipe and the washing water containing the inflow microbubble and the washing water circulating and circulating by the above- The cleaning effect of the washing machine according to the present invention can be maximized.

The impeller 31E of the pressurizing pump 31 is rotated at a speed of 1500 rpm or more to convert the air sucked into micro bubbles of 50 mu m or less to be mixed and dispersed evenly in the washing water, And then attached to a foreign substance such as fine contaminants floating in the washing tank 10 and floated in the washing tank 10 like a foreign object to remove the foreign substance from the outlet 12 .

The pressurizing pump 31 according to the present invention maximizes the floatation effect of fine contaminants while cleaning and sterilizing foreign matter such as fine contaminants with a small amount of air by mixing the microbubbles. Therefore, compared with the conventional ultrasonic washing machine, So that fine contaminants can be easily separated from the object C to be cleaned.

Further, the air suction pipe 31E of the pressurizing pump 31 may further include an air flow rate controller (not shown). It is possible to more easily prevent cavitation in the pump by controlling the amount of air to be sucked by 5 to 10% of the weight of the washing water sent out by the pressurizing pump 31 through the air flow rate controller.

While the present invention has been described with reference to the accompanying drawings, it is to be understood that the invention is not limited thereto. Various modifications, alterations, and permutations of the present invention may be made by those skilled in the art. Should be construed as falling within the scope of protection of the present invention.
