Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water spouting adapter and a shower head installed in, for example, a bathroom, which can be reformed so as to improve the operation of discharging water to the shower head as compared with the existing one. Regarding

[0002]

2. Description of the Related Art For example, a hot water supply and shower facility provided in a bathroom is generally capable of supplying hot water by a discharge pipe to a wall-fixed hot and cold water mixing tap and shower by a shower head connected to this hot and cold water mixing tap by a hose. Is. There is also a shower-specific facility in which a hot and cold water mixing plug is provided in the wall, and a pipe connected to the plug is exposed to the wall surface and a shower head is connected to the pipe.

[0003]

In a hot and cold water mixing valve having a shower head, in addition to an on-off valve that can switch the flow path between the water discharge pipe side and the shower head side and can adjust the flow rate,
The simplest structure is to provide a temperature control valve that changes the mixing ratio of water and hot water.

In such a hot and cold water mixing valve, for example, even when the flow rate is set to an appropriate amount when using a shower, when the shower is temporarily interrupted and then the shower is taken again, the operation procedure is to open the on-off valve once and then open it. Become. For this reason, even if an appropriate amount is set at the beginning when used, the valve opening of the on-off valve shifts when used again, and this must be readjusted, which is not preferable in terms of usability.

Further, even in a hot and cold water mixing tap for a shower built into a wall, the operability is the same because the temperature setting is necessary every time it is used.

In order to improve the operability of such a hot and cold water mixing tap facility, the existing hot and cold water mixing tap must be replaced with a multifunctional one. However, replacement of the hot and cold water mixing tap is not preferable from the viewpoint of cost, and there is a problem in meeting demand.

The problem to be solved in the present invention is to provide an adapter for a water spouting device which can be used more easily in a facility such as a shower by utilizing an existing hot and cold water mixing tap as it is.

[0008]

The present invention is an adapter incorporated in a flow path between a faucet main body connected to a water supply and / or hot water supply source and a water discharger connected downstream thereof.
It is characterized by comprising an electromagnetic valve that opens and closes a flow path to the water discharger, a controller that controls the opening and closing operation of the electromagnetic valve, and an operation switch that opens and closes the electromagnetic valve.

A battery may be used as the power source for the electromagnetic valve and controller.

[0010]

For example, in an existing facility of a faucet body of a hot and cold water mixing faucet and a shower head connected to the faucet body, by providing an adapter between the faucet body and the shower head, the faucet can be operated only by operating the operation switch. Water and hot water can be supplied from the main body to the shower head. In this case, even when suspending the shower, only the operation on the adapter side is required, so the setting of the flow rate on the faucet body side does not change, and the supply to the shower head at the initially set flow rate is maintained. .

Further, by using a battery as a power source, it can be installed in the bathroom or the like at the time of remodeling without a facility such as an outlet.

FIG. 1 is a perspective view showing an example in which the water spout adapter of the present invention is used for connecting a hot and cold water mixing tap installed in a bathroom and a shower head, and FIG. 2 is a perspective view showing the hot and cold water mixing tap and the adapter. FIG. 3 is a right side view of the hot and cold water mixing valve shown with the internal structure of the adapter.

In the figure, a faucet body 1 for mixing hot and cold water is fixed to a wall by connecting a flow path to the water supply pipe and hot water supply pipe provided in the wall by means of a water supply leg pipe 1a and a hot water supply leg pipe 1b on the back thereof. Has been done. And from this faucet body 1 to the hose 3
The shower head 2 is connected to the hanger 2a and can be used by hanging it on the hanger 2a.

These faucet body 1 and shower head 2
Are all existing equipment, and before reforming by the adapter of the present invention, existing equipment in which the hose 2a is connected to the connection cylinder 1c at the back of the faucet body 1 as in the case of the conventional hot and cold water mixing tap with shower. And Then, by incorporating the adapter 5 between the connecting cylinder 1c and the hose 2a, reforming is performed for the purpose of improving the hot water supply operation to the shower head 2.

Various hot and cold water mixing taps have been conventionally used, but in the example shown in the figure, an on-off valve and a thermostat mixing function for switching the flow passages on the water discharge pipe 1d side and the shower head 2 side and for adjusting the flow rate are used. The front opening and closing handle 1e and the temperature adjusting handle 1f are provided at the right end.

FIG. 4 is a plan view schematically showing the outline of the structure of the internal flow passage in the faucet body 1. The flow passage on the side communicating with the water supply leg pipe 1a and the hot water supply leg pipe 1b flows on one axis. Valve elements 4a and 4b whose path area can be changed are connected to the temperature control handle 1f. These valve elements 4a and 4b are housed in a mixing chamber 4c in which water and hot water are mixed. In addition, a cylindrical opening / closing valve seat 4 is provided at a position that crosses the mixing chamber 4c.
d is provided, and the valve element 4e, which is alternately seated on both axial end surfaces of the opening / closing valve seat 4d, is connected to the opening / closing handle 1e.
The valve element 4e can be brought into contact with and separated from the valve seat surfaces at both ends of the on-off valve seat 4d, and one valve seat surface is connected to the base end of the flow path to the water discharge pipe 1d side and the other valve seat surface is connected to the connecting cylinder 1c. The base end of the flow path to the side.

In such a flow channel structure, the opening / closing handle 1
The flow path to the water discharge pipe 1d side or the connection cylinder 1c side can be switched by the operation of e. Therefore, the adapter 5 connected to the connection tube 1c communicates with the mixing chamber 1c while the flow path on the side of the water discharge pipe 1d is closed, and hot water can be supplied to the shower head 2.

The adapter 5 is a housing 5a in which an electromagnetic valve unit 6 driven by a battery is incorporated. The valve unit 6 uses a latching solenoid, and is provided with a solenoid 6a and a valve unit 6b capable of opening and closing a flow path by the solenoid 6a.

The valve unit 6b is connected to the connecting pipe 6c from its peripheral surface.
Is protruded from an opening 5b opened on the front surface of the housing 5a, and a cap nut 6d is connected and fixed by connecting a flow path to the connection cylinder 1c of the faucet body 1. Further, at the lower end of the valve unit 6b and downstream of the on-off valve portion, a connecting seat 6e that projects from the lower end of the housing 5a and connects the base end of the hose 3
Equipped with.

A controller 7 is provided inside the housing 5a.
Equipped with a battery box 6f for accommodating a battery (not shown) and a valve unit 6 by a push button type operation switch 8 provided on the surface of the housing 5a.
To operate. The controller 7 controls the valve unit 6b of the valve unit 6 to open when the operation switch 8 is pressed once, and to close the valve unit 6b when pressed again.

To install the adapter 5 between the existing faucet body 1 and the shower head 2, the connection pipe 6c of the valve unit 6 is connected to the connection pipe 1c of the faucet body 1 by the cap nut 6d.
And connecting the hose 3 to the connection seat 6e.

In the hot and cold water mixing tap and shower equipment in which the adapter 5 is thus incorporated, the operation switch 8 should be pressed during the period in which the open / close handle 1e is operated to connect the mixing chamber 4c to the connecting cylinder 1c side. Shower head 2
It can be stopped by showering with water from the shower.

When the shower head 2 is used, its flow rate is determined by the valve opening between the opening / closing valve seat 4d and the valve element 4e by the opening / closing handle 1e. For this reason, for example, in the case where the shower is used again after being temporarily interrupted while taking an appropriate amount, it is convenient to use the opening / closing handle 1e to stop the water discharge in the existing equipment and then set again. With such an operation, it is difficult to immediately adjust the amount of water discharge that is close to the appropriate amount when the water was first used.

On the other hand, by providing the adapter 5, the operation switch 8 is used when the shower is temporarily suspended.
Press to stop water, and press again to start water discharge. Further, since the opening / closing handle 1e is not touched by this operation, the same shower sprinkling amount as that before the interruption can be obtained. Therefore, not only the simple operation of pressing the operation switch 8 but also the setting of the flow rate is not affected, and the usability is significantly improved.

FIG. 5 is a perspective view showing a shower facility in which the adapter 5 is mounted on a wall, and FIG. 6 is a vertical sectional view showing a connection structure of the adapter 5 and piping in this example.

In this example, the faucet body 9 of the hot and cold water mixing faucet is embedded in the wall, and the surface thereof is provided with a handle 9a capable of both temperature setting and flow channel setting. A variety of such hot and cold water mixing plugs are known as conventional wall-embedded plugs. The mixed water supply pipe 9b connected to the faucet body 9 is buried in the wall and the adapter 5 is installed. It is an existing facility in which the flow path to the shower head 10 with the hanger 10a is connected so as to face the wall surface side at a part, and this is reformed by the adapter 5.

Valve unit 6 accommodated in adapter 5
Is installed in the reverse direction of the previous example, and its connecting pipe 6
c is arranged so as to project from the opening 5c on the back of the adapter 5, and the opening 5b on the front side is closed by a decorative cover 5d. If the lower end and the upper end of the valve unit 6 can be rotated coaxially with each other, the connection pipe 6c can be easily distributed to the back side.

Since the connecting pipe 6c is connected to the supply pipe 9b in the wall, a nipple socket-shaped joint 11 is connected to the supply pipe 9b as shown in FIG. Then, the connection pipe 6c is connected to the joint 11 by the cap nut 6d, and the hose 10b of the shower head 10 is connected to the connection seat 6e at the lower end.

It should be noted that it is preferable to provide a cover 5e for concealing the connection portion with the supply pipe 9b on the back side of the adapter 5 and on both left and right ends thereof.

Even when the wall-fixable adapter 5 is used, it is possible to operate the water discharge and the water stoppage from the shower head 10 only by pushing the operation switch 8, and the setting of the flow rate after the temporary interruption can be performed first. It becomes unnecessary like the example of.

Further, the adapter 5 can be used both for fixing to the back surface of the faucet body 1 and for fixing it to the wall by simply changing the posture of the valve unit 6 incorporated therein, which is effective as a general-purpose product.

In the embodiment, the adapter for supplying water and hot water to the shower head is used, but it is needless to say that the present invention can be applied to other equipment having various spouts connected to existing faucets.

[0033]

According to the present invention, by newly installing an adapter between the existing faucet body and the water discharger downstream thereof, the setting of the flow rate of water supply / hot water supply from the faucet body does not change. It can be supplied and stopped by an adapter.
Therefore, for example, usability can be obtained without the trouble of adjusting the flow rate by the opening / closing valve on the faucet body side, etc., and the remodeling in which the function of the existing product is further enhanced is realized.
