Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to, for example, a water supply for an automatic faucet in which a spout body is provided on the upper surface of a washbasin and a faucet valve body is provided below the washbasin. The present invention relates to a pipe connection structure.

[Conventional technology]

Recently, automatic faucets that automatically discharge and stop water by the function of sensors have come to be widely used in public facilities that frequently use hot water or water. In such an automatic faucet, for example, as shown in FIGS. 4 and 5, the spout body 1 is installed upright on the washbasin 2, and the faucet valve body 3 is installed below the washbasin 2. In many cases, the spout body 1 and the faucet valve body 3 are installed separately. This is the faucet valve main body 3 to the upper surface side of the washbasin 2.
This is because, if such an arrangement is made, the number of protrusions increases, the appearance becomes poor, the dust and the like easily adhere, and the cleaning becomes difficult.

By the way, in the conventional automatic faucet shown in FIGS. 4 and 5, the faucet valve body 3 is of a type including a hot and cold water mixing faucet 4 and an electromagnetic valve portion 5. Faucet valve body 3
The water discharge main body 1 and the water discharge main body 1 are connected by a water supply supply pipe 6 using a copper pipe.

Thus, such an automatic faucet does not require the user to directly touch the faucet metal fitting itself, and the sensor is embedded in a portion such as the spout 7 of the spout body 1 or a wall surface. All you have to do is extend it. The sensor turns on (opens) a valve (not shown) of the electromagnetic valve unit 5 by detecting the hand of the user. As a result, hot water adjusted to a desired temperature by the hot and cold water mixing faucet 4 will be supplied from the water supply supply pipe 6 to the water outlet 7 through the electromagnetic valve,
Water is automatically discharged. When the user pulls out the hand from this water discharge state, the sensor now turns the electromagnetic valve off (closes it) and automatically shuts off the water.

[Problems to be solved by the device]

However, in the conventional automatic faucet, the spout body 1 and the faucet valve body 3 are connected by a water supply supply pipe 6 made of a copper pipe. Therefore, it is necessary to braze the connection, and it is necessary to bend and form the supply pipe 6 into a predetermined shape in advance according to the route of piping. Further, there is also a drawback that assembly with other parts cannot be performed unless the dimensional accuracy of the bent supply pipe 6 is increased.
As a result, the whole connection work is extremely complicated and time-consuming.

[Means for Solving the Problems]

SUMMARY OF THE INVENTION The present invention has been made by improving and removing the above problem in view of the conventional problems described above, and is intended to provide a water supply pipe connection structure for an automatic faucet, which has excellent workability and does not require strict dimensional accuracy. .

The feature of the means adopted by the present invention to solve the above-mentioned problem is that the faucet valve body and the spout body are installed separately from each other in the automatic faucet. By making the main body separable, the outlet of the faucet valve main body and the water outlet of the water outlet main body are connected by a water supply pipe made of a flexible resin tube inserted through the inside of the water outlet main body. is there.

[Action]

In the present invention, the spout body is separable, and the resin tube inserted through the spout body serves as a passage for hot water, which facilitates the manufacture and assembly of the spout body. Further, the outlet of the faucet valve body and the water outlet of the water outlet body are connected by a flexible resin tube. Therefore, the resin tube can be freely arranged at the time of connection, and the arrangement work can be freely performed even in the water discharge port main body. In addition, the connection can be made with a band member that is widely used, which is extremely easy.

〔Example〕

The structure of the present invention will be described below with reference to the embodiments shown in the drawings.

1 to 3 relate to an embodiment of the present invention. FIG. 1 is a front view showing the entire automatic faucet 10, FIG. 2 is a side view of the same, and FIG. 3 is a spout body. FIG. 11 is a vertical sectional view of 11. As shown in these drawings, the spout body 11 includes a washbasin 12
It is mounted and fixed on the upper surface side of. A water faucet valve body 13 is provided below the washbasin 12. The faucet valve body 13 includes a hot and cold water mixing faucet 14 and an electromagnetic valve portion 15, and in this respect, it is the same as the conventional case. Thus, in this embodiment, as clearly shown in FIG.
The spout body 11 is vertically separable, that is, it is composed of two parts, an upper half 11a and a lower half 11b.
It is united by 30,31. A hollow portion 11c is formed inside the spout body 11, and a silicone tube 18 inserted through the hollow portion 11c allows a spout attached to the outlet of the electromagnetic valve portion 15 and the tip of the spout body 11. The water spout 17 is connected. This silicon tube 18 has flexibility and heat resistance.

As described above, in this embodiment, since the connection between the outlet of the electromagnetic valve portion 15 and the water outlet portion 17 of the water outlet main body 11 is made by the silicon tube 18, a clip for normal piping is used. Connection work can be performed using 19 or a band member (not shown), and since brazing is not necessary, it is extremely simple. Further, since the silicon tube 18 is flexible, it is possible to freely arrange the silicon tube 18 while avoiding interference with other members. In particular, as shown in FIG. 3, the interior space of the spout body 11 is extremely narrow and often interferes with other members. It is easy to make a detour or to change the direction a little to avoid this. In short, since it is not necessary to connect with a copper pipe as in the conventional case, it is not necessary to bend and braze the copper pipe into a predetermined shape or to braze, and the whole pipe connecting work is extremely simple.

By the way, in the automatic faucet 10 of this embodiment, an ultrasonic sensor 21 for detecting the hand of the user is provided in the vicinity of the spout 17 of the spout body 11. This ultrasonic sensor
The output of the receiver 21 on the side of the receiver is connected to the electromagnetic valve unit 15 as shown by the chain line in FIG. 1 to control ON / OFF of the electromagnetic valve. Therefore, when the user extends his / her hand below the spout body 11, the ultrasonic sensor 21 detects this and turns on (opens) the electromagnetic valve.
Therefore, the hot water adjusted to the desired temperature by the hot and cold water mixing faucet 14 is discharged from the silicon tube 18 through the water discharge port 17. This state is maintained while the ultrasonic sensor 21 detects the hand of the user. When the user pulls out the hand from this state of use, the ultrasonic sensor 21 detects this and turns off the electromagnetic valve to bring it into a water-stop state. In this embodiment, since the spout body 11 is separable, even when the ultrasonic sensor 21 is attached to the tip of the spout body 11 as shown in the figure, the output signal is transmitted to the electromagnetic valve section 15. Since the conducting wire 22 for doing so can be easily inserted through the inside of the water outlet main body 11, there is an advantage that the wiring work becomes very simple.

By the way, the present invention is not limited to the above-described embodiments, but can be appropriately modified. For example, the silicon tube 18 may be a tube made of resin such as nylon or polypropylene. The resin tube may be at least flexible. It is desirable to have heat resistance. Also, the automatic faucet 10
In this embodiment, hot water adjusted to a desired temperature is discharged by the hot and cold water mixing faucet 14, but it goes without saying that the hot and cold water mixing faucet 14 may not be provided.

[Effect of device]

As described above, in the present invention, the flexible resin tube is used to connect the outflow port of the water faucet valve body and the water outlet part of the water spout body. Can be freely arranged by detouring or changing the direction in order to avoid interference with other members. Therefore, unlike the case of using a conventional copper pipe, a troublesome work such as bending and forming into a predetermined shape or brazing is unnecessary, and the pipe connecting work is extremely simple. In addition, since the water discharge port main body is separable and the configuration in which the hot and cold water passage is formed by the resin tube inserted through the inside is adopted, strictness is not required in the molding dimensions and the assembly dimensions, and therefore, , Facilitating the manufacture and assembly of the spout body.
Furthermore, even during maintenance, it is convenient because the attachment / detachment and piping can be easily performed.
