Description

[Detailed Description of the Invention] The present invention relates to a shower device that is devised so that it can be easily used by being attached to a household instantaneous water heater or water faucet.

For example, a shower device used in a home bathroom is usually installed by installing piping from a water heater into the bathroom, and connecting a hose on the shower nozzle side to a faucet attached to this piping.

Therefore, it is not a good idea from a profit standpoint to provide a water heater for a shower system separate from that for a bathtub, and showers are not currently used in ordinary households without a bathroom.

In view of the above points, the present invention makes it possible to easily install a shower system without the need for special piping work by using an instantaneous water heater installed in the kitchen of a general household, and it can also be attached to a water faucet. In other words, the present invention is intended to provide a shower device configured to be fully usable as a garden water sprinkler, and embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an embodiment in which this shower device is connected to a general household instantaneous water heater, and shows the leak outlet pipe 2 of the instantaneous water heater 1.
An automatic on-off valve device body 3 is connected to the automatic on-off valve device body 3, and this automatic on-off valve device body is attached with a flow path switching valve device as described later.
A hose 6 of a shower device body 5 with a manual on-off valve device is connected to one side of the flow path via a connection valve device body 4, and the hot water supplied from the instantaneous water heater 1 is directed to the shower device body 5 side. It is configured so that it can be sent out at any time.

Next, details of each of the above components except for the instantaneous water heater 1 will be explained.

As shown in FIG. 2, the automatic opening/closing valve device body 3 has a liquid inlet 12 on the upper side of a main body 11 and a liquid outlet 13 on the lower side, and has a valve seat inside which is opened and closed by a spherical valve body 14. It is partitioned into two chambers, an upper chamber 16 and a lower chamber 17, with 15 as a boundary.

A working chamber 18 is connected to the outer side of the upper chamber 16, and a pressure receiving body (piston) 20 placed under the bias of a spring 19 is slidably provided in the working chamber 18.

The tip of the actuating rod 21 protruding from the pressure-receiving actuating body 20 is connected to the upper chamber 1.
6, and is normally in the forward position together with the pressure-receiving actuating body 20, pressing the valve body 14 against the spring 22,
is opened to allow communication between the upper chamber 16 and the lower chamber 17.

Further, the operating chamber 18 and the lower chamber 17 are connected through a communication port 23, and when the liquid pressure on the liquid discharge passage side including the lower chamber 17 increases abnormally when water flows out, the pressure receiving actuating body 20 is activated by the spring 19. The actuating rod 21 is moved backward against the valve body 14.
When the pressure is released, the valve seat 15 can be closed by the valve body 14 as shown in FIG.

Further, a branch port 24 is provided on the side wall of the lower chamber 17 facing above the liquid outlet 13, and a switching valve 25 that can open and close the liquid outlet 13 is provided in the lower chamber 17.
5 is placed on a valve seat 27 connected to the liquid outlet 13 under the bias of a spring 26.

The shaft portion 25a of the switching valve 25 passes through the liquid outlet 13 and connects to the main body 1.
1, and its tip abuts on an operating shaft 28 rotatably mounted horizontally on the main body 11, and when the operating shaft 28 is rotated with a knob 29, a circumferential direction provided on the circumferential surface of the shaft 28 is rotated. The switching valve 25 is raised and lowered by the inclined groove 28a and the spring 26, and the liquid outlet 13 can be opened and closed.

A connecting cylindrical portion 30 is connected to the branch port 24 so as to protrude from the main body 11. Inside the connecting cylindrical portion 30, a valve seat 31 is normally closed under the bias of a spring 32. A spherical valve body 33 placed in is movably accommodated.

Further, a connector 34 to which a rubber hose 6 extending from a shower device body 5, which will be described later, is connected can be freely fitted to and removed from the connecting cylinder part 30, and as shown in FIG. When fitted, the valve body 33 separates from the valve seat 31 against the spring 32 and opens the liquid passage port 35.
It constitutes a connection valve device body 4 that can open the liquid passage port 35 when the two are fitted together.

That is, the press rod 36 is housed in the connector 34 so as to be movable along the axial direction, and the base 37 of the press rod 36 is inserted into the connector 34.
The receiver fixed therein is positioned between the part 38 and the partition plate 39, and the pressing rod 36 is normally moved to the right in FIG.
is in contact with.

When the connector 34 is fitted onto the connecting cylindrical portion 30, the tip of the pressing rod 36 comes into contact with the valve body 33, and the pressing rod 36 retreats until the base portion 37 comes into contact with the receiving portion 38, and at that position. Since the tip of the pressing rod 36 presses the valve body 33 in the opposite direction, the valve body 33 moves away from the valve seat 31 against the force of the spring 32 and is held in the open position as shown in FIG.

Therefore, by opening the liquid passage port 35, hot water from the automatic opening/closing valve device body 3 side is transferred to the branch port 24, the liquid passage port 35, and the pressing rod 36.
It can be sent to the shower device body 5 side through a passage 41 such as a slot formed in the shower device itself and a hose 6.

Note that a means is adopted for connecting the connecting cylinder portion 30 and the connector 34 by a one-touch operation.

That is, a shallow dish-shaped recess 42 is provided on the circumferential surface near the root of the connecting cylinder 30, and a hole 44 for accommodating a ball 43 is provided in a portion corresponding to the recess 42 on the connector 34 side. A part of the ball 43 accommodated in the accommodation hole 44 can be freely locked in the recess 42.

Then, the ball 4 is placed in the housing portion 45 formed in the connector 34.
3 is slidably provided, and this presser 46 is placed under the bias of a spring 47, so that a part of the ball 43 can normally protrude to the inner surface of the connector 34. .

Further, a knob 48 protruding outward from the connector 34 is connected to the pusher 46, and when the pusher 46 releases the pressure on the ball 43 by operating the knob 48, the ball 43 moves toward the inside of the accommodating portion 45. Since it can be moved slightly, the connector 34 can be easily removed from the connecting tube portion 30.

49 is a long hole for sliding the knob 48, and 50 is a tightening nut for connecting the hose 6 to the connector 34.

Next, the shower device body 5 connected to the tip of the hose 6 will be explained. As shown in FIGS. 1 and 4, the shower device body 5 is separated from the nozzle part 51 and the valve cylinder 51a, and both They are joined together using screw means or the like.

An on-off valve 54 and a check valve 55, both of which are placed under the bias of springs 52 and 53, are provided in the valve number cylinder 51a, and the shaft portion 56 of the on-off valve 54 passes through a valve seat 57. , its tip abuts on an operating shaft 58 rotatably suspended horizontally on the valve container cylinder 51a, and when the operating shaft 58 is rotated with a knob 59, the shaft 58
a circumferential inclined groove 60 provided on the circumferential surface of the spring 52;
As a result, the on-off valve 54 moves toward and away from the valve seat 57, and the liquid discharge port 61 can be opened and closed.

Further, the check valve 55 is moved away from the valve seat 62 against the spring 53 in response to hydraulic pressure from the hose 6 side, so that the valve number cylinder 51a can communicate with the hose 6 side.

In addition, 63 is a guide part of the on-off valve 54 having a liquid passage gap 63a such as a slot, 64 is a guide part of the check valve 55 having a similar liquid passage gap 64a, and 65 in FIG. 1 is the nozzle part 51. This is a shower plate installed at the tip of the shower plate.

Since the present invention is as described above, in the case of the illustrated embodiment, when hot water is supplied from the instantaneous water heater 1, the hot water passes through the automatic opening/closing valve device body 3 and the connection valve device body 4 to the shower device body 5 side. and is discharged from the shower plate 65 of the nozzle section 51.

In this case, the switching valve 25 of the automatic on-off valve device body 3 is operated by the operation shaft 2.
8 is pressed onto the valve seat 27, and the hot water flows only to the shower device body 5 through the branch port 24.

During this liquid discharge, if the liquid pressure on the liquid discharge path side rises unreasonably due to, for example, stepping on the hose 6, the valve element 14 of the automatic on-off valve device body 3 will automatically move to the valve seat 15, as described above. This completely prevents accidents such as the hose 6 bursting due to the supply of hot water to the liquid discharge path being stopped.

When the shower is not used, the operating shaft 58 of the shower device body 5 is operated, and the valve seat 54 is opened and closed by the spring 52.
7 to close the liquid discharge port 61, and on the other hand, operate the operation shaft 28 of the switching valve 25 of the automatic opening/closing valve device body 3 to release the liquid discharge port 13 from the valve seat 27. It becomes possible to use the instantaneous water heater 1 in the same way as in a normal case.

Furthermore, since the shower device body 5 is provided with a check valve 55, it is possible to completely eliminate the inconvenience of sewage flowing in from the nozzle portion 51 side.

As described above, the present invention allows the shower device to be easily connected to an instantaneous water heater, water faucet, etc. without the need for special piping work using iron pipes, making it possible to use it safely and conveniently. The connection of the shower device body to the automatic opening/closing valve device body has the advantage in handling that it can be easily and quickly connected by a one-touch operation between the connecting tube and the connector, and its practical value is extremely great.

In addition, when using this shower device attached to an instantaneous water heater, it is desirable to provide a relief valve (not shown) in the middle of the leak outlet pipe for safety.
