Regarding a hot water mixer faucet equipped with.

[Conventional technology]

Conventionally, hot and cold water mixing faucets have, for example, one in which a flow path is formed in a cast body, and a valve unit containing a built-in valve element, and a pedestal and a cover that cover the top and bottom surfaces of this valve unit are integrated. There is a composition.

FIG. 6 is an exploded perspective view showing the installation of a conventional valve unit and a pedestal. At the bottom of the valve unit 1, a connecting pipe 2 for water supply and a connecting pipe 3 for hot water supply are connected to the water supply source and the hot water supply source, respectively. ing. At the lower ends of the water supply connecting pipe 2 and the hot water supply connecting pipe 3, leg pipes 4 and 5 for connecting to a water supply pipe and a hot water supply pipe (not shown), which are piped below the installation surface, are extended downward, respectively. Fixed.

A pedestal 10 for fixedly supporting the valve unit 1 that integrates the connecting pipes 2 and 3 for water supply and hot water supply includes:
Attachment ports 11 and 12 are provided through which the leg pipes 4 and 5 are inserted to position the valve unit 1 at a predetermined position. The opening shape of the mounting port 11 is similar to that of the leg pipe 4,
The valve unit 1 has a rectangular shape that matches the substantially regular square flanges 6 and 7 at the upper end of the valve 5, and the posture and position of the valve unit 1 with respect to the pedestal 10 are determined by the flanges 6 and 7 and the mounting port 1.
The structure is obtained by the fitting relationship with 1 and 12.

[Problem that the invention attempts to solve]

By the way, the positional relationship between the water and hot water supply connecting pipes 2 and 3 connected to the valve unit 1 and the respective leg pipes 4 and 5 is symmetrical with respect to the center of the valve unit 1, as shown in Fig. 7a. This is normal. In this case, for example, if you try to use the water supply connecting pipe 2 on the right side of Figure a for the hot water supply side, both the connecting pipes 2, 3
The hot water supply connecting pipe 3 does not point in the direction of the valve unit 1, as shown in FIG. 7b, unless the axis of the valve unit 1 forms a 45 degree angle with the longitudinal center line of the valve unit 1. Therefore, it is necessary to manufacture connecting pipes for water supply and hot water supply as separate parts, respectively.

Moreover, when the shapes of the parts are different in this way, two types of jigs are required for supplying water to the pedestal 10 and for assembling and fixing the connecting pipes 2 and 3 for hot water supply.

In this way, depending on the opening shape of the mounting ports 11, 12 of the pedestal 10 and the positional relationship between the ports 11, 12 and the valve unit 1, the left and right water supply and hot water supply connecting pipes 2,
3 cannot be shared with each other. Therefore, there are difficulties in terms of cost and management due to the increase in the number of parts, and the use of different jigs for assembly work has an undesirable effect on productivity improvement.

This invention was devised in view of the above-mentioned problems, and its purpose is to reduce the number of parts and improve productivity by sharing the connecting pipes for water supply and hot water supply. do.

The hot water mixer faucet in this embodiment is of a single lever type in which the mixing ratio and flow rate of hot water and water are adjusted by a lever handle A provided at the upper end.

The valve unit 1 contains two ceramic valve plates that operate in conjunction with the lever handle A to open and close the flow paths of hot water and water from the water supply connecting pipe 2 and the hot water supply connecting pipe 3. The valve unit 1 is integrated with the valve unit 1 and is configured to supply mixed water from a water spout B located at the front end.

The valve unit 1 is fixed to a pedestal 10, and its upper surface is covered by a cover 20 connected to the pedestal 10 by screws 21.

Figure 4a is an exploded perspective view of the water supply and hot water supply connecting pipes 2 and 3 (hereinafter referred to as "connecting pipes 2 and 3") and leg pipes 4 and 5, and Figure 4b is a plan view after assembly. It is a diagram. The connecting pipes 2 and 3 are bent pipes whose upper end portions are connected to the valve unit 1 and whose lower end portions are connected to the leg pipes 4 and 5, and whose axes are parallel to each other. Further, the leg pipes 4 and 5 have regular hexagonal flanges 6 and 7 formed at their upper ends, and a male screw 8 for connection to a water supply pipe and a hot water supply pipe (not shown) is provided on the outer periphery of the lower part.

To assemble the connecting pipes 2, 3 and leg pipes 4, 5, insert the lower ends of the connecting pipes 2, 3 from the upper ends of the leg pipes 4, 5,
After positioning, fix by soldering.
The connecting pipes 2 and 3 are positioned relative to the leg pipes 4 and 5 so as to have the relationship shown in FIG. 4b. In other words,
The axes of the connecting pipes 2 and 3 are regular hexagonal flanges 6,
The positional relationship is such that the center of any one side of 7 is perpendicular to that side. With this assembly, the flanges 6 and 7 become symmetrical with respect to the axes of the connecting pipes 2 and 3. In addition to this positional relationship, the flanges 6 and 7 can be made bilaterally symmetrical with respect to the axis by arranging the connecting pipes 2 and 3 so that their axes are the same as the diagonal lines of the flanges 6 and 7.

The connecting pipes 2 and 3 connected in the above manner are connected to the valve unit 1 at an angle α that is symmetrical with respect to the longitudinal center line of the valve unit 1, as shown in FIG. .

The mounting holes 11 and 12 have a circular shape with a diameter that allows the male threads 8 of the leg tubes 4 and 5 to be inserted therethrough. Then, the tongue piece 13 that receives the three sides of the hexagonal flanges 6 and 7 is raised up, and the flanges 6 and 7 are positioned by this tongue piece 13, thereby connecting the connecting pipes 2 and 7.
The attitude of the unit 1 toward the unit 1 is set to a predetermined attitude.

The tongue pieces 13 are used to restrain and position the three sides of the hexagonal flanges 6 and 7, and the axes of the connecting pipes 2 and 3 pass through the centers of the mounting openings 11 and 12, and these tongues The pieces 13 are arranged symmetrically about the axis.

The above valve unit 1, pedestal 20 and cover 20
The assembly is done in the following manner.

First, connect the connecting pipe 2 to the valve unit 1 in the manner described above.

Here, the flanges 5 and 6 of the leg pipes 4 and 5 connected to the connecting pipes 2 and 3 are regular hexagonal shapes that are symmetrical to the axes of the connecting pipes 2 and 3, so the connecting pipes 2 and 5 on the water supply side and the hot water supply side, 3 can be shared with each other.

In other words, as is clear from FIG. Furthermore, the flanges 5 and 6 on the water supply side and the hot water supply side are symmetrical with respect to the longitudinal center line of the valve unit 1. Therefore,
The connecting pipe 2 on the water supply side can be used as is for the hot water supply side,
As a result, the connecting pipes 2 and 3 with leg pipes 4 and 5 connected to the valve unit 1 can be provided in one piece.

Furthermore, in the case described in the conventional example, the connecting pipe 2,
3 and the leg pipes 4 and 5 required different jigs for the water supply side and the hot water supply side, but by making them into the same parts, it can be manufactured using only one jig.

[Effect of idea]

As explained above, in the hot water mixing faucet of the present invention, the flange shape of the leg pipe of the connecting pipe that supplies water to the valve unit and the mounting opening shape of the pedestal that receives this flange are aligned with the axis of the connecting pipe. It is symmetrical. Therefore, even if the angle between the longitudinal centerline of the valve unit and the axis of the connecting pipe is not 45 degrees, the flange and the mounting port can maintain a symmetrical relationship with respect to the centerline of the valve unit. As a result, the connecting pipe and the leg pipe are one common member that can be used for piping on the water supply side and the hot water supply side, making it possible to reduce the number of parts and improve productivity.
