Description

Description: TECHNICAL FIELD The present invention relates to a shower head assembly, and more particularly to a water supply means for supplying water from a shower water supply unit,
A shower head connected to an outlet of the water supply means.

BACKGROUND ART Water authorities are constantly striving to maintain an ever-increasing supply of water in response to growing populations and increasing demand for water. One approach adopted is to set a criterion for the maximum amount of water passing through the shower system within a given time, but many shower systems using conventional showerheads exceed the required criterion, I can't achieve it.

Accordingly, it is a first object of the present invention to provide a showerhead assembly which, while reducing the amount of water passing through the showerhead assembly, maintains a relatively high water pressure during shower watering and maintains a wide shower watering range. It is.

If two or more people want to shower together in the same shower area for water saving or other reasons, or in clubs or schools, multiple showerheads are connected to a single water outlet and many people There is also a need for such a shower system when taking a shower. The present invention limits the amount of hot water that can be used each time when a relatively large number of people, such as, for example, a large family or a sports team, need to take a shower past the time when it is likely that hot water will not be available. It is also applicable when it is necessary to save water for showering, and it takes a relatively long time to boil alternative water in the hot water supply unit, and that long delay is inconvenient. You. To date, as far as I know, no shower system satisfies this need.

DISCLOSURE OF THE INVENTION Accordingly, the present invention provides a showerhead assembly comprising a water supply means for supplying water from a shower water supply unit and a showerhead connected to an outlet of the water supply means, wherein the showerhead is provided around the head. A peripheral chamber communicating with the outlet and a pair of walls facing in the thickness direction of the shower head, and communicating between the watering chamber, the peripheral chamber and the watering chamber therebetween. Defining a communication part around the watering chamber; and forming a plurality of watering holes through which water from the watering chamber becomes a small stream to spray water on one of the pair of wall parts; The cross-sectional dimension of the part is smaller than the cross-sectional dimension of the peripheral chamber,
Forming a constricted portion for reducing the amount of water flowing to the water supply means.

Further, the water supply means may be provided with a second constricted portion for reducing the amount of water.

Further, a second outlet may be provided in the water supply means, and a second shower head may be connected to the second outlet. In this case, the second shower head may have substantially the same structure as the shower head. Desirably, it is desirable to provide the water supply means with a valve assembly capable of shutting off water supply to the second shower head.

By forming a constricted portion at the communication part between the peripheral chamber of the shower head and the watering chamber, the amount of water flowing to the water supply means is reduced, but the water pressure in the peripheral chamber is maintained,
Water flows into the watering chamber from the periphery thereof, the water pressure distribution in the watering chamber becomes uniform, and water is sprinkled well from each watering hole.

When multiple showerheads are connected to and supplied from a common water supply, two or more conventional sized showerheads are combined from a common water supply when combined in a single assembly. A relatively strong and continuous stream of water flows from each showerhead compared to when the furthest showerhead chamber contains a fairly small amount of water and produces a relatively low pressure improper stream of water. In the above case where the chamber contains a fairly small amount of water, the water supply from each water hole to the other water supply is rather than the water supply to the conventional showerhead being a relatively strong flow, each being a separate trickle. Adjustments to a relatively small amount, such as falling across the showerhead surface as a single stream, along with watering from the holes, may even result in non-constant flow patterns.

DETAILED DESCRIPTION OF THE DRAWINGS One embodiment of the present invention is described with reference to the accompanying drawings as follows.

That is, FIG. 1 is a top perspective view of an embodiment of the present invention in which a pair of shower heads forming a double shower head connected to a common water supply unit are combined, and FIG. 1
FIG. 3 is a partially cutaway plan view of the showerhead assembly shown in FIG. 3, FIG. 3 is a sectional view taken along line 3-3 of FIG. 2, and FIG. It is one bottom view of.

BEST MODE FOR CARRYING OUT THE INVENTION A double shower head assembly comprising a pair of shower heads 10 and 11 is illustrated with reference to the drawings. The shower head 10 has a peripheral chamber extending around its periphery.
10a, and a sprinkling chamber 10b defined between a pair of wall portions 12a, 12b opposed in the thickness direction of the shower head 10. Water supplied to the sprinkling chamber 10b is supplied to one of the wall portions 12a.
The water is sprayed as a small stream from the plurality of water spray holes 38 formed at the bottom. The shower head 11 is also similar to the shower head 10,
There is provided a peripheral chamber and a watering chamber defined between a pair of walls 13a and 13b opposed in the thickness direction of the shower head 11.

In this embodiment of the present invention, the water is connected to a water supply section provided on an adjacent wall and is combined with a pivot joint 15 on the wall in the same manner as in a conventional shower head, so that the arrangement angle of the shower head is vertical. Water is supplied to the shower heads 10 and 11 via a water supply passage 14 which can be adjusted in the direction. The water supply channel 14 communicates with the inside of the water distribution / valve housing 16,
The water distribution / valve housing 16 includes a coaxial branch 17 extending to one end thereof and supported in close engagement with a closure member 18 threaded to the end. Further, the branch passage 17 is formed by connecting the inside of the housing to a water supply chamber 21 communicating with the water supply passage 14, a water distribution chamber 22 for one shower head 10, and a valve chamber connected to another shower head 11. Insert the partition walls 19 and 20 which are separated from each other by a distance of 23. The water distribution chamber 22 has an outlet 24 for sending water inside the showerhead 10, while the valve chamber 23 has an outlet 25 for sending water inside the other showerhead 11. The fork 17
Has a pair of diametrically aligned holes 26 through which water in the water supply chamber 21 flows to the branch 17. The fork further has a pair of diametrically aligned holes 27 communicating with the interior of the water distribution chamber 22 for the showerhead 10, and is thus a conventional hot and cold tap coupled with the shower device. Depending on what feeds the water supply channel 14, the water supply chamber 21, the hole 26, the branch 17 (which narrows the water flow) and the hole 27
It is clear that water is supplied to the shower head 10 via the water distribution chamber 22 and the outlet 24.

One end of the branch 17 that passes through the septum 20 and reaches the valve chamber 23 opens into the valve chamber 23 and forms a valve seat for cooperation with the valve assembly 28. The valve assembly 28 includes the housing
16 comprising a box 29 screwed into the cooperating end of said box 29;
Spindle threaded on the outer periphery operated by handle 36 in cooperation with axial bore threaded on the inner periphery through
30 passes through it. The inner end of the spindle 30 reaches a valve support member 31, which has at its inner end an axial blind hole 32 for receiving a handle 33 of a check valve 34 provided with a water stop washer 35. The check valve 34 is adapted to close the end of the branch 17 when the water pressure downstream of the valve chamber 23 exceeds the feed pressure.
Is axially movable to automatically move axially toward a valve seat formed at one end of the shaft. In the position of the valve 34 shown in FIG. 2, the water is guided to the valve chamber 23 through the branch 17 that narrows the water flow, and then supplied to the shower head 11 through the outlet 25. When the check valve is completely closed, the check washer 35 of the check valve 34 is seated on a valve seat provided at one end of the branch passage 17, and the valve chamber 23 is closed.
To prevent the shower head 11 from being supplied with water. In such a situation, only the showerhead 10 is operable. By gradually pulling the check valve 34 away from the valve seat, a large amount of water is gradually introduced into the valve chamber 23 and supplied to the shower head 11.

Each showerhead 10, 11 is connected to a respective outlet 24, 25 in a respective peripheral chamber. In this case, the shower heads 10 and 11 may be rotatably connected to the outlets 24 and 25 in order to allow the angle adjustment of the shower heads 10 and 11.

Between the pair of walls 12a and 12b of the shower head 10,
The watering chamber 10b and a communication portion 10c around the watering chamber 10b that connects the peripheral chamber 10a and the watering chamber 10b are further defined. The cross-sectional dimension of the communication part 10c is smaller than the cross-sectional dimension of the peripheral chamber 10a. In the shower head 11, a communication part similar to that of the shower head 10 is defined between the pair of walls 13a and 13b.

As shown in FIG. 4, the shower head spouts 38 are continuously arranged in an arc and a total of 62 spouts at each shower spout, usually a conventional shower spout having 133 spouts. In comparison, there are a total of 124 watering holes.

As described above, when a single shower head is provided in connection with the present invention, or when only the shower head 10 of the present embodiment of the present invention is operated, the inside of the peripheral chamber 10a of the shower head 10 is provided. The water can be conserved due to the narrowing of the communication portion 10c, which causes the water pressure to rise, and the water flow to sprinkle remains relatively strong. When water is supplied to the second shower head 11 in the case of the preferred embodiment of the present invention when the valve assembly 28 is opened, excessive water pressure of the shower head 10 causes water to flow out of the shower head 11 and both shower heads Sufficient shower pressure is achieved at 10,11.
