As shown in FIG. 11, a conventional shower device is provided with a large number of pressure water jet holes 53 of small diameter on a shower discharge surface 52 provided in a shower main body 51, and a large number of filamentous water streams 54 jetted from the holes. By colliding with the cleaning surface 12,
The adhered dirt is removed or dissolved and washed.

Therefore, most of the detergency depends on the striking force of the filamentous water stream 54 and the amount of water, so that a high pressure and a large amount of pressure water are required to obtain a sufficient detergency, and the effect of saving water is expected. Can not.

EXAMPLE A first example of the present invention will be described below. In FIG. 1, 1 is a shower main body, 2 is an ejector mechanism, 3
Is an injection nozzle, 4 is an air suction part, and 5 is a gas-liquid mixing pipe. Here, the inner diameter of the gas-liquid mixing pipe 5 is larger than the nozzle diameter of the injection nozzle 3, and the gas-liquid mixing pipe 5 is arranged substantially coaxially via the air suction portion 4.

Further, 6 is a discharge port, 7 is a shower discharge surface, and the discharge port 6 is open to the shower discharge surface 7. 8
Is an annular protrusion, and protrudes from the shower discharge surface 7 so as to surround the discharge port 6.

Reference numeral 9 denotes a leading edge of the annular protrusion, which further protrudes from the discharge port 6. 10 is an air intake hole, 1
Reference numeral 1 is a jet nozzle support plate, and 12 is a surface to be cleaned.

When pressure water is supplied in the above-mentioned structure, the water flow injected into the air suction portion 4 by the injection nozzle 3 passes through the gas-liquid mixing pipe 5 having a larger inner diameter as shown in FIG. However, since the filamentous water stream 13 containing no bubbles is discharged, the filamentous water stream 13 can be used in almost the same manner as the conventional shower apparatus, although it is thicker and smaller in number than the conventional shower apparatus.

From this state, the shower main body 1 is attached to the surface to be cleaned 1
2 to bring the distal end edge 9 of the annular protrusion into contact with the surface 12 to be cleaned, whereby the filamentous water stream 1 discharged as shown in FIG.
3 starts to be stored in the pseudo cleaning tank 14 formed by the surface to be cleaned 12, the inner wall of the annular protruding portion 8 and the shower discharge surface 7, and starts to accumulate from the time when the stored water surface 15 reaches the position where the discharge port 6 is blocked. Mixing of the liquids starts, and as shown in FIG. 4, the gas-liquid mixed fluid 16 is instantly generated in the entire pseudo cleaning tank 14 as a strong vortex flow.

Thus, with respect to the surface to be cleaned 12 forming the bottom surface of the pseudo cleaning tank 14, the striking force by the direct impact of the gas-liquid mixed fluid 16 discharged from the discharge port 6 and the stirring force by the strong vortex flow, Furthermore, ultrasonic vibrations generated when the mixed air bubbles are decomposed are added to act as a strong cleaning power.

After that, the gas-liquid mixed fluid 16 temporarily retained in the pseudo cleaning tank 14 passes through the gap between the abutting portion between the tip end edge 9 of the annular protrusion and the surface 12 to be cleaned together with the separated or dissolved dirt component. Is discharged.

At this time, if the tip end edge 9 of the annular protrusion is made of an elastic material such as silicon rubber, the gas-liquid mixed fluid 16
This is convenient because the discharge pressure can be used to appropriately open the gap between the surface to be cleaned 12 and discharge.

Further, by making the annular protrusion 8 detachable, the annular protrusion 8 can be replaced and used depending on the object to be cleaned, which improves convenience.

In addition, by supplying ozone, a detergent, an abrasive or the like to the air suction port 10, further improvement of the cleaning power can be expected.

Here, a description will be given of the mechanism in which gas-liquid mixing is started in an instant. Generally, when a high-speed water stream is injected into the atmosphere, a negative pressure is generated between the surface of the high-speed water stream and the atmosphere. However, when the tip end edge 9 of the annular protrusion and the surface 12 to be cleaned are sufficiently separated, the discharge port 6 And the atmosphere are communicated with each other, the negative pressure in the gas-liquid mixing pipe 5 is released, the air and the water flow are separated, and the same filamentous water flow 13 as in the conventional shower device is discharged.

On the other hand, the leading edge 9 of the annular protrusion and the surface 12 to be cleaned
The discharged filamentous water flow 13 starts to be stored by contacting the above, and when the stored water surface 15 reaches the position where the discharge port 6 is blocked, the communication between the atmosphere and the discharge port 6 is cut off, and the gas-liquid mixing pipe A large negative pressure is generated within 5 in an instant.

Due to this negative pressure, the water flow is divided into fine particles, and air is sucked into the spaces between the fine particles to be discharged as a gas-liquid mixed fluid 16.

As a matter of course, when the distance between the leading edge 9 of the annular protrusion and the surface 12 to be cleaned is gradually increased from this state, the gas-liquid Mixing ceases and turns into a filamentous stream.

Next, a second embodiment of the present invention will be described below. 5, 17 is a drainage passage, to discharge the discharged water was peeled or dissolved dirt components finishing cleaning operations, it is possible to arbitrarily set the position and drainage direction, it is possible to limit the drainage path, usability Is improved.

[0041] Incidentally, another can be set also discharge water passing path, such as in FIG. 6, also in mere outdoor air communicating drilling, can exhibit the same effect.

Next, a third embodiment of the present invention will be described below. In FIG. 7, reference numeral 18 denotes an annular protrusion formed of a water-permeable material such as sponge, which is configured to allow drainage through this water-permeable material. Therefore, while draining from the outer wall surface of the water-permeable annular protruding portion 18, the leading edge 9 of the annular protruding portion 9 is discharged.
The surface 12 to be cleaned can be rubbed by means of this, and a further cleaning effect can be expected, and it is suitable for a shower device for bath, face washing or car washing.

Next, a fourth embodiment of the present invention will be described below. In FIG. 8, reference numeral 19 designates a dense brush-shaped annular protrusion, which is drained from the outer wall surface of the brush-shaped annular protrusion 19 as in the case of the third embodiment, and is cleaned by the annular protrusion tip edge 9. The surface 12 can be rubbed, and even with this configuration, a further cleaning effect can be expected, and it is also suitable for a shower device for car washing, a jet water jet type oral cleaning toothbrush, and the like.

Further, a fifth embodiment of the present invention will be described below. In FIG. 9, 20 is a small diameter pressure water injection hole,
The shower discharge surface 7 is opened together with the discharge port 6. Reference numeral 21 denotes an air suction pipe, one end of which is opened to the air suction portion 4 and the other end of which is opened to the outside air. With the above configuration, the pressure water is supplied to both the injection nozzle 3 and the pressure water injection hole 20 of the ejector mechanism 2, and the gas-liquid mixed fluid 16 is supplied from the shower discharge surface 7.
The filamentous water stream 13 is discharged into the pseudo cleaning tank 14.

When the distance between the front edge 9 of the annular protrusion and the surface 12 to be cleaned is increased from this state, the gas-liquid mixed fluid 16 discharged from the gas-liquid mixing pipe 5 is transformed into a filamentous water flow, and the pressure water is jetted. Since it is mixed with the filamentous water stream 13 ejected from the hole 20, it can be used by a user who has become a conventional shower device without feeling uncomfortable.

Finally, a sixth embodiment of the present invention will be described below. In FIG. 10, 22 is a pressure water supply path switching mechanism, and an example of a ball valve 23 is described as an example of the switching mechanism.

At the position of the ball valve 23 in the figure, the pressure water is supplied only to the injection nozzle 3 of the ejector mechanism 2,
Only the gas-liquid mixed fluid 16 is discharged into the pseudo cleaning tank 14. On the other hand, when the ball valve 23 is moved to the position A in the figure, it is supplied only to the pressure water ejection hole 20,
Can be used as a conventional shower device. Further, when the ball valve 23 is moved to the position B in the figure, the pressure water is supplied to both the injection nozzle 3 and the pressure water injection hole 20 of the ejector mechanism 2, which is the same as the fifth embodiment. It becomes a state. Therefore, the functions of the conventional shower device and the shower device of the present invention can be appropriately switched according to the preference of the user, and usability and convenience are improved.

Although the present specification mainly describes a shower device used at home, it goes without saying that the present invention can also be applied to an industrial shower device used in a factory or the like.
