Description

[Detailed Description of the Invention] This invention relates to a shower/rectifier that can be attached to a gas instantaneous water heater, a water tap, a hot water supply pipe, or the tip of a water supply pipe to serve both as a shower and a rectifier tube.

Various types of shower rectifiers as described above have been proposed in the past. For example, there are shower tubes that are rotatably installed at the lower end of the hot water supply pipe, and can be switched between the shower state and the rectification state by rotating the shower tube by hand, but both hands are required to rotate the shower tube. It is.

Also, although there is no need to rotate the shower tube, some shower tubes can be switched by alternately pressing push buttons that protrude from the front and back of the shower tube. However, this type of shower has problems in that it is cumbersome to operate and the operating force is heavy because push buttons protruding from the front and rear sides of the shower tube must be pressed alternately.

This idea aims to solve the problems of conventional shower rectifiers as mentioned above.
By operating the seesaw-type pushbutton exposed on the outside of the shower tube, the valve lever inside the shower tube rotates, and the valve at the tip of the lever alternately opens and closes the two valve ports inside the shower tube, allowing the shower to enter or exit the shower mode. It can be switched to a rectifying state.

The details of this invention will be explained below based on an embodiment shown in the accompanying drawings.

The partition wall 10 is provided with a shower valve port 23 and a flow regulating valve port 24 which are alternately opened and closed by a valve body 22, and a rubber valve seat 25 is attached to the valve ports 23 and 24. .

The seesaw type button 17 is shaped such that one of its outer sides protrudes from the outer periphery of the shower tube 8 to close either the valve port 23 or 24 of the valve body 22 at the end of the valve lever 15.

Reference numeral 28 denotes a shower nozzle plate having a large number of small holes 27, and the female screw on the inside of its peripheral wall 29 is screwed into the male screw on the outer periphery of the lower part of the shower cylinder 8 to fix it.
At this time, the ring packing 30 is placed on the peripheral wall 29.

As shown in FIG. 1, the upper end opening 33 of the water diversion elbow 32 is connected and fixed to the cylindrical part 31 provided integrally at the lower part of the rectifying valve port 24, and the lower end opening 34 is aligned concentrically with the shower cylinder 8. At the same time, this elbow 32
A disk 35 coaxial with the lower end opening 34 is provided on the outer periphery, and a male thread is formed on the outer periphery.

Reference numeral 37 in FIGS. 1 and 5 is a rectifying tube, and a female thread provided on a large diameter portion 38 at the upper end of the rectifying tube is screwed into a male thread of the disk 35 to fix it. The lower end discharge port 39 of the flow straightening tube 37 passes through the central opening of the shower nozzle plate 28 and projects downward.

Reference numeral 40 denotes an inner cylinder fitted into the rectifying cylinder 37, whose upper end is enlarged and provided with a plurality of protrusions 41 on the outside as shown in FIG. 5, leaving an appropriate gap outside the opening 34. It is worshiped. The lower end of this inner cylinder 40 has a small diameter and is concentrically fitted within the discharge port 39 of the straightening cylinder 37 with an appropriate gap.

Further, a thin-walled cylinder 42 is fitted on the lower side of the lower end of the inner cylinder 40, and a plurality of protrusions 43 provided on the outside of this cylinder 42 are brought into contact with the inner periphery of the lower end of the rectifying cylinder 37.
0 has a radial rectifier plate 4 as shown in Figure 4.
Fix 4.

In the above configuration, FIGS. 1 and 2 show a state in which the valve lever 15 is on the shower side. At this time, since the valve body 22 closes the valve port 24, water or hot water from the hot water supply pipe 1 flows into the upper chamber 11, and then flows into the lower chamber 12 through the open valve port 23. It is discharged as a shower from a large number of small holes 27 in the shower nozzle plate 28 at the lower end.

Further, when the protruding side of the button 17 shown in the solid line in FIG. 2 is pressed, the button 17 rotates together with the valve lever 15 as shown in chain lines in FIG.
3 is closed, and the valve port 24 is opened.

Therefore, water or hot water flowing from the hot water supply pipe 1 flows from the upper chamber 11 through the valve port 24 into the water diversion elbow 32, and flows into the inner cylinder 40 from the lower end opening 34 thereof.

The water or hot water that has flowed into the inner cylinder 40 is rectified by the rectifier plate 44 and discharged downward. At this time, if the temperature of the hot water is high, the separated steam will rise and reach the inner cylinder 40.
Since the hot water is discharged from the upper end through the discharge port 39 through the gap between the inner cylinder 40 and the straightening cylinder 37, the steam and water are completely separated and the hot water can be safely discharged. However, the configuration of this rectifying section is free.

Further, the valve body is not limited to the spherical shape as in the embodiment, but may be of any shape similar to a hemispherical shape or a sphere.

As mentioned above, this idea divides the interior of the shower cylinder into an upper chamber and a lower chamber by a partition wall, and this partition wall has a shower valve port that communicates the upper and lower chambers, and the upper chamber communicates with the rectifier cylinder. A seesaw-style button is fitted into the recessed button mounting part provided on a part of the peripheral wall of the shower tube, and the vertical shaft integrated with the button is inserted into the through hole at the top of the mounting part. A valve lever in the upper chamber is integrally provided at the upper end of this vertical shaft, and the end of this valve lever has a spherical or Since it is equipped with a similar movable valve body and a spring that presses the valve body against the valve opening, the shower tube can be opened by simply operating the seesaw-type button exposed on a part of the outer periphery of the shower tube with one hand. The valve lever inside moves, allowing you to freely perform shower discharge and rectified discharge.

Also, the operating force is light and the seesaw-style buttons don't stick out too much, making it easy to carry on your body. Furthermore, the valve body is spherical or close to this shape and is pushed downward by a spring.
When the valve port is closed, a portion of the valve body fits into the valve port and is fixed, so that the valve can be switched reliably.
