[Structure] An amount of air corresponding to the opening of an air suction amount adjusting valve 9 is sucked from an air suction pipe 8 into a suction chamber 5, and bubble mixed water is jetted from a diff user 6 toward a member to be cleaned 10 to be cleaned. By colliding the cleaning water and the bubbles against the body 10, the foreign matter adhering to the body to be cleaned 10 is peeled off by the synergistic effect of the impact force when the cleaning water collides and the impact force when the bubbles burst. Remove and wash.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bubble mixing / cleaning nozzle for spraying water mixed with bubbles for cleaning.

[0002]

2. Description of the Related Art Hitherto, a means for cleaning a body to be cleaned by injecting cleaning water with high pressure has been well known. In this type of conventional cleaning means, foreign matter adhering to the cleaning body is peeled off and removed only by the impact force generated when the cleaning water collides with the cleaning body. Therefore, a cleaning water supply source capable of injecting cleaning water at a considerably high pressure is required, and although the cleaning facility becomes large and the initial cost and running cost are high, it is actually excellent. It has the drawback that cleaning cannot be expected.

[0003]

The problem to be solved is that in the conventional cleaning means, the foreign matter adhering to the object to be cleaned is separated and removed only by the impact force when the cleaning water collides with the object to be cleaned. However, even though the cleaning equipment becomes large and the initial cost and the running cost increase, it is practically impossible to expect excellent cleaning.

[0004]

According to the present invention, there is provided a throttle unit having an inlet connected to a washing water supply source, a suction chamber having the throttle unit inserted therein, and a diff user connected to the front side of the suction chamber.
An air suction pipe branch-connected to the suction chamber, wherein an air suction amount adjusting valve is provided in the air suction pipe, and the impact force at the time of collision of washing water and the case where bubbles burst Through the synergistic effect with the impact force, the purpose of achieving excellent cleaning by peeling and removing foreign matter adhering to the object to be cleaned was achieved.

[0005]

According to the present invention, the cleaning water supplied from the cleaning water supply source to the inlet is squeezed by the squeezing portion to convert its pressure energy into velocity energy and jetted at high speed in the direction of the diff user. While passing through the diff user, the pressure is recovered and jetted toward the object to be cleaned. The pressure of the suction chamber becomes low because the wash water moves at high speed inside the suction chamber. Therefore, by opening the air suction amount adjustment valve, the air of the amount corresponding to the opening is sucked into the suction chamber from the air suction pipe, and the air-water mixed fluid, that is, the air-bubble mixed water is moved toward the diff user at high speed. It is jetted, and while passing through the diff user, the pressure is recovered and jetted toward the object to be cleaned. As a result, the cleaning water and the bubbles collide with the object to be cleaned, and the particles are attached to the object to be cleaned by the synergistic effect of the impact force when the cleaning water collides and the impact force when the bubbles burst. Performs excellent cleaning by peeling and removing foreign matter. On the other hand, as the opening degree of the air intake amount adjustment valve increases and the air intake amount increases, the proportion of bubbles in the bubble mixed water increases, and the occupancy rate of bubbles on the cross section of the diff user increases. The water occupancy on the passage cross section is reduced corresponding to the increase in the air bubble occupancy rate, the flow velocity of water can be increased, the cleaning power can be increased, and the amount of water required for exhibiting the same cleaning power can be reduced. .

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing an embodiment of the present invention.
In this figure, a bubble mixing and cleaning nozzle 1 includes a throttle portion 4 having an inlet 2 connected to a pump 3, a suction chamber 5 having the throttle portion 4 inserted therein, and a differential user 6 connected to the front side of the suction chamber 5. An air suction pipe 8 is branched and connected to the suction chamber 5, and an air suction amount adjusting valve 9 is provided in the air suction pipe 8.

With such a configuration, the cleaning water supplied from the pump 3 to the inlet 2 of the bubble mixing cleaning nozzle 1 is throttled by the throttle unit 4 to convert its pressure energy into velocity energy and diffract it. It is injected at high speed in the direction of the user 6, and while passing through the differential user 6, the pressure is recovered and the object 10 to be cleaned is injected. The pressure of the suction chamber 5 becomes low as the cleaning water moves at high speed inside the suction chamber 5. Therefore, by opening the air suction amount adjusting valve 9, the amount of air corresponding to the opening degree is sucked into the suction chamber 5 from the air suction pipe 8, and the air-water mixed fluid, that is, the air-bubble mixed water is transferred to the differential user 6. Will be injected at high speed in the direction of, and while passing through the differential user 6, the pressure will be recovered and injected toward the article to be cleaned 10.

As a result, the cleaning water and the bubbles collide with the object to be cleaned 10, and the object to be cleaned 10 is synergized by the impact force at the time of collision of the cleaning water and the impact force when the bubbles burst. Excellent cleaning can be performed by peeling and removing foreign matter adhering to the.

The opening degree of the air intake amount adjusting valve 9 becomes large,
As the air suction amount increases, the proportion of bubbles in the bubble-mixed water increases, and the occupancy rate of bubbles on the passage cross section of the diff user 6 increases, which corresponds to the increase of bubble occupancy rate on the passage cross section. The occupancy rate of water becomes smaller, the flow velocity of water can be increased, the cleaning power can be increased, and the amount of water required for exhibiting the same cleaning power can be reduced.

On the other hand, the air suction amount adjusting valve 9 is controlled to be fully open / closed or to be controlled to an intermediate opening degree to change the air suction amount and intermittently change the cleaning power for the object 10 to be cleaned. The effect can also be increased. Since the cleaning effect is increased by opening / closing the air suction amount adjusting valve 9 as described above, the air suction amount adjusting valve 9 can be controlled with a small operating force. That is, the air suction amount adjusting valve 9 can be controlled with a small operating force as compared with a means for intermittently changing the washing force by opening / closing the water amount adjusting valve to change the flow rate of the washing water. it can. Therefore, since a valve with good response can be used, fine control is possible. It is also possible to suppress the occurrence of water hammer.

[0011]

As described above, according to the present invention, the foreign matter adhering to the object to be cleaned is separated and removed by the synergistic effect of the impact force at the time of washing water collision and the impact force at the time of bubble burst. Therefore, it is possible to exert an excellent cleaning effect as compared with the conventional cleaning that depends only on the impact force at the time of collision of the cleaning water, and it is possible to reduce the amount of water required for exhibiting the same cleaning force. Therefore, large-scale cleaning equipment with high initial cost and running cost is unnecessary.
