Abstract

PROBLEM TO BE SOLVED: To improve the operability of a lever in a single lever type mixing faucet, in which a mixing valve is installed at the front end of a rotatable water discharge pipe. SOLUTION: A water discharge pipe 1 consisting of an upstanding section 2 disposed in upright in approximately the vertical direction from a counter A and an extending section 3 extended in approximately the horizontal direction from the upper section of the upstanding section 2 is mounted rotatably around a vertical axis P, and a mixing valve 4 capable of adjusting the temperature and flow rate of cold and hot water discharged from a water discharge opening 5 formed to an underside by a single lever 6 is set up at the front end of the extending section 3. The temperature of cold and how water is adjusted by rotating the lever 6 left and right in the periphery of the axis Q of the extending section of the water discharge opening 1 at that time, and the flow rate is controlled by upward and downward operation. Accordingly, the temperature of cold and hot water can conveniently by adjusted by a single hand without the accompanying turn of the lever and the water discharge pipe as seen in conventional devices, and operavility can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mixing faucet having a single lever type mixing valve at the tip of a water discharge pipe attached to a sink or a sink.

[0002]

2. Description of the Related Art Conventionally, a mixing valve is provided at the tip of a water discharge pipe provided on a counter of a sink or a washstand, and the temperature and flow rate of hot and cold water can be adjusted by operating a single lever. FIG. 1 of the official gazette (FIG. 4 of the present application) is available. Briefly describing FIG. 4, the mixing faucet is a rotatable rising portion 21 that rises from near the sink.
An extension portion 22 that extends obliquely forward from an upper portion of the rising portion 21; a single-lever-type hot / cold water mixing valve 23 provided at a tip of the extending portion 22;
And a water outlet 24 provided on a lower surface of the water mixing valve 23. The lever 25 extending horizontally on the upper surface of the hot and cold water mixing valve 23 is rotated up and down to perform water discharge from the water outlet 24 and flow rate adjustment. When the lever 25 is rotated to the left, the water discharge temperature increases, and when the lever 25 is rotated to the right, the water discharge temperature decreases.

[0003] Therefore, since the extending portion 22 extends forward from the upper portion of the rising portion 21, the space below the extending portion 22 is large, so that a large pot or tableware is washed under the extending portion 22. And the water mixing valve 23 is provided at the end of the extension portion 22, so that the lever 25 of the water mixing valve 23 is close to the user, so that the lever 25 does not need to be extended so much. Easy to do.

[0004] However, the rising part of the mixing faucet is rotatable around the vertical axis E, while the lever operation for adjusting the temperature of the hot and cold water is also performed horizontally around the vertical axis F of the mixing valve. When the lever is rotated, the rising part also rotates together, so if you do not support the rising part with the other hand, you can not rotate the lever only left and right, unless you use both hands It was inconvenient because the temperature could not be adjusted.

SUMMARY OF THE INVENTION An object of the present invention is to improve the operability of a lever in a single lever type mixing faucet in which a mixing valve is mounted at the tip of a swivelable water discharge pipe.

[0006]

According to the present invention, there is provided a water discharge pipe comprising a rising portion which stands substantially vertically from a counter, and an extending portion which extends substantially horizontally from an upper part of the rising portion, around a vertical axis. A single-lever mixing faucet equipped with a mixing valve capable of adjusting, with a single lever, the temperature and flow rate of hot and cold water discharged from a spout provided on the lower surface at the end of the extension portion. In the above, the lever adjusts the temperature of the hot and cold water by rotating left and right around the axis of the extension of the water discharge pipe, and adjusts the flow rate by operating up and down.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. As shown in FIG. 1, the single-lever type mixing faucet A of the present invention is such that a water discharge pipe 1 rising from a counter B of a sink or a basin can be swiveled around a vertical axis P, and stands substantially vertically from the counter B. Rising part 2
And an extended portion 3 formed by gently bending the upper portion of the rising portion 2 in a substantially horizontal direction and extending.
A mixing valve 4 for adjusting the flow rate and temperature of hot water and a water outlet 5 disposed on the lower surface of the mixing valve 4 for supplying hot water adjusted by the mixing valve 4 are provided.

Such a single lever type mixing faucet A
Is a mixing valve for adjusting water discharge, water stoppage, flow rate and temperature in a wide range because the position of water discharge from the water discharge port 5 can be arbitrarily adjusted because the water discharge pipe 1 can be turned left and right. Since the pipe 4 is provided at the end of the water discharge pipe 1, the lever 6 of the mixing valve 4 can be operated without extending the hand to the vicinity of the counter B, and the operability is good and extremely convenient.

A water supply pipe and a hot water supply pipe (not shown) communicating with a water supply source and a hot water supply source are inserted into the water discharge pipe 1, and a valve chamber 7 of the mixing valve 4 has a water supply pipe and a hot water supply pipe. In the valve chamber 7, a fixed plate 8 and a movable plate 9 made of ceramics or resin are superposed and housed, and the movable plate 9 is connected to the lever 6 via a handle shaft 10,
When the lever 6 is moved upward from the water stoppage state shown in FIG.
1 and 2, the temperature of the hot water decreases when the lever 6 is turned to the right around the extension portion axis Q as shown in FIGS. 1 and 2, and the temperature of the hot water decreases when the lever 6 is turned to the left. Get higher.

In the present invention, the temperature is adjusted by rotating the lever of the mixing valve provided at the tip of the water discharge pipe to the left and right. In this case, the lever rotates around the axis of the extension portion. Therefore, when the lever is operated, the action is performed in a direction different from the rotation of the water discharge pipe with respect to the vertical axis. Therefore, even if the lever is rotated left and right, the water discharge pipe does not rotate in the same direction.

Although the embodiment of the present invention has been described above, the present invention can be configured in other forms. For example, in the present invention, water is discharged by moving the lever upward from the water stop state. May be moved downward from the water stop state to discharge water, and the lever may be attached upward instead of downward as in the present invention. Further, the water discharge pipe may change the inclination angle of the extending portion with respect to the rising portion.

[0012]

According to the present invention, a water discharge pipe comprising a rising portion which stands substantially vertically from the counter and an extending portion which extends substantially horizontally from the upper portion of the rising portion is rotatable about a vertical axis. A single lever type mixing faucet equipped with a mixing valve capable of adjusting the temperature and flow rate of hot and cold water discharged from a water discharge port provided on a lower surface at a tip of the extension portion, Adjusts the temperature of hot and cold water by rotating left and right around the extension axis of the water discharge pipe, and adjusts the flow rate by operating up and down, so that the lever and water discharge pipe do not rotate together as in the past, The temperature of hot and cold water can be adjusted favorably with one hand, and operability can be improved.
