BACKGROUND OF THE INVENTION
The present invention relates to a faucet device for an automatic faucet equipped with an automatic sensor or touch switch used in a kitchen or a washroom.
[0002]
[Prior art]
When installing an automatic sensor or touch switch near the spout, it is necessary to provide a water passage and a signal line inside the faucet, and the spout can be rotated on the horizontal plane with the base as a reference. When trying to do so, it is necessary to pass the signal line through the rotating part, and thus the structure becomes complicated.
For example, in the faucet device shown in Japanese Utility Model Laid-Open No. 3-86159, a pipe member and a spout inner pipe fixed to a faucet main body in a watertight and rotatable manner are watertightly fixed, and the inner pipe is connected with a spout outer pipe having an irregular shape. The signal line was passed through the gap between the double pipes. This signal line was passed to the bottom of the counter through a hole provided in the faucet body. Furthermore, a decorative cover was used to hide the holes and signal lines.
Moreover, in the faucet device shown in Japanese Utility Model Publication No. 3-125862, the signal line is passed through the spout water passage, and the spout pipe is constituted only by the water passage portion.
[0003]
[Problems to be solved by the invention]
However, the conventional faucet device has the following problems.
In the faucet device shown in Japanese Utility Model Publication No. 3-86159, the inner pipe receives strength, so it has to be made of a highly rigid material, for example, metal, and the outer pipe is an external part, so it requires external quality. . For this reason, plating or the like has to be used, and both the inner pipe and the outer pipe are expensive. Further, since the inner tube and the outer tube are in contact with each other, when hot water is passed through the inner tube, the heat is also transmitted to the outer tube, which may cause burns. Furthermore, since the inner pipe is rigid, it is easily affected by the shape of the spout.
Further, in the faucet device shown in Japanese Utility Model Publication No. 3-125862, since the signal line is passed through the water passage portion, at least two signal line penetration portions exist in the water passage portion, and a waterproof structure must be taken. In addition, since the signal line comes into contact with water, when it is used for drinking water or the like, elution of components from the signal line has to be taken into account, which causes a problem in safety.
Furthermore, since the spout tube is only a water passage portion, when hot water is passed through, the spout itself becomes hot and may cause burns.
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a water faucet device that is provided with a heat insulating structure in a spout, enhances the waterproofness of a signal line, and is easy to assemble.
[0004]

And the front side has a second pipe connected to the water discharger joint and the base side is connected to the main body joint in a watertight state. In addition, spout says the pipe part containing the water outlet provided in the front side of the faucet body.
Since the faucet device according to the present invention has a double pipe structure of the first pipe member and the second pipe member, it is possible to make it difficult to transfer heat by providing an air layer in the gap therebetween, for example, As a result, the outer first tube is not heated by hot water or hot water passing through the second tube.
[0005]
Here, the faucet main body part has a spout insertion port for inserting the base part of the spout on the upper part, and a connecting part provided at the base side end part of the main body part joint and communicating with the second pipe member. A spout connection port to be connected to is provided with a certain distance on the same axis. Thereby, a spout difference was included port and spout connection port on the same axis, since it is provided having a predetermined distance, the spout is easily rotated, it is possible to reduce the lateral play .
Moreover, the part in which the spout insertion port is formed may be a separate part, and the faucet body may be an assembly structure. If it is a separate part, the spout base can be inserted into the spout insertion port, the signal line can be connected, and then the spout can be connected to the spout connection port.
Here, a notch portion that communicates between the first tube material and the second tube material may be provided in the fitting portion of the faucet body portion at the side portion of the body portion joint. By doing in this way, a signal wire can be directly passed through the interior of the faucet main body portion without going out of the faucet device from between the first tube material and the second tube material.
[0006]
The second pipe member may be rotatably connected to at least one of the main body joint and the water discharger joint. By doing so, even if the second pipe is twisted during assembly, it can be easily restored.
Furthermore, it is preferable that the second tube material is a flexible tube. When a flexible tube is used, insertion into the first tube material is easy, and the shape of the first tube material needs less consideration of the shape of the second tube material, so that the degree of freedom is increased.
The spout body joint and the faucet body may be provided with stopper means for regulating the rotation angle of the spout. If a stopper for restricting the rotation angle is provided, the internal signal line can be prevented from being caught.
