[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet for mixing hot water and water, and more particularly to a hot water side by connecting a hot water side flow path to a hot water supply device, which is suitable for use only with a hot water side operating handle. It relates to a hot and cold mixing tap.

[0002]

2. Description of the Related Art The most basic construction of a hot water mixer tap is to connect a water side and a hot water side flow path to a main body thereof, and to a water valve seat and a hot water valve seat located at ends of these flow paths. This is a two-valve system in which the valve body is brought into and out of contact with an external operation handle. In such a hot / water mixer tap, the degree of opening of the valve body with respect to the water valve seat and the hot water valve seat can be changed by operating the water-side and hot-water-side operation handles, and mixed water at the required temperature and flow rate can be obtained.

[0003] A standard type of a two-valve water / water mixer tap is provided with an operating handle for water on the upper surface on the right side and an operating handle for hot water on the left side when the main body is viewed from the front. Many are arranged symmetrically.

On the other hand, hot water is supplied to a hot / water mixer tap in a multi-family house or the like, generally using equipment for supplying hot water of a relatively high temperature from a provided hot water boiler or the like. And when using, set the valve opening of the water side and hot water side,
An operation of obtaining an appropriate mixed water temperature is performed.

[0005] Instead of such a hot water supply system, for example, as described in Japanese Utility Model Application Laid-Open No. 3-69064, a hot water heater connected to a hot and cold water mixing tap itself has a temperature adjusting function so that a hot water supply temperature can be adjusted in advance. Some facilities set the temperature to a suitable temperature and supply water only with the operating handle on the hot water side.

[0006]

However, when the operation handles on the water side and the hot water side are in symmetrical positions, for example, when the face is held down during hair washing or face washing, the handle is operated by groping. , It is easy to mistake the water side and the hot water side.

[0007] In terms of design, the water-side and hot-water-side operation handles are often used as common parts, and most of them have a cylindrical or polygonal cross section. For this reason, when the handle is touched by groping, it is difficult to determine whether the handle is on the water side or on the hot water side, which also causes a mistake in the operation.

Further, in a facility for supplying a suitable temperature of hot water from a water heater, the hot water can be used as it is, so that it is possible to turn the operation handle on the hot water side and not to handle the operation handle on the water side. . However, since the operation handle on the hot water side is generally arranged on the left side of the main body,
There are aspects that are difficult for right-handed people to use.

As described above, in the two-valve hot water mixer tap, the positions and shapes of the operation handles for water and hot water with respect to the main body are likely to be too uniform, and the operation on the water side and the operation on the hot water side are erroneous. Not only that, there is also a tendency for lack of adaptability to, for example, equipment for adjusting the temperature of hot water to an appropriate temperature in a water heater.

A problem to be solved in the present invention is that in a hot and cold water mixing tap having two operation handles for a hot water side and a hot water side, it is easy to operate the hot water side without making a mistake in the water side and the hot water side. And make it safe to use.

[0011]

This invention SUMMARY OF THE INVENTION The water supply passage, the body having a discharge passage of the hot water supply passage and mixed water, for the flow path of hot water and for water to open and close operation from the water supply passage and hot water supply passage A hot-water mixer tap having two operation handles, wherein a hot-water heater connected to the hot-water supply path itself has a temperature adjusting function to set a hot-water supply temperature to an appropriate temperature in advance, and only a hot-water-side operation handle is provided. in the mixing faucet for hot water supply, the operation for the water together with the operating handle for the front Symbol hot water provided on the upper surface of the main body
A handle is provided on a side surface of the main body .

The operation handle for the hot water and the operation for the water
Can Rukoto with different forms of the operating handle for the handle water.

[0014]

[0015]

By providing one of the two operation handles on the upper surface side of the main body, the mutual positional relationship between the operation handles for water or hot water is broken from, for example, a target arrangement around the main body, and each of them becomes independent. It is possible to externally show that the steering wheel has a different function, improve the appeal to the user, and prevent mistaken operation.

If the hot water handle is located on the upper surface side of the main body, it is the most noticeable position for the user and the operation can be easily performed by putting the hand over the user, so that the reliability of the hot water supply operation is improved. I do.

[0017]

When the operation handle is made to be a rotary type and a lever portion is provided on the outer periphery thereof, the operation can be performed by hanging on a fingertip, and handling without slipping can be performed.

[0019]

FIG. 1 is a front view showing an embodiment of a hot and cold water mixing tap according to the present invention, FIG. 2 is a plan view thereof, and FIG. 3 is a longitudinal sectional view taken along line AA of FIG.

In the figure, a water pipe 2a and a water pipe 2b are connected to the back of the main body 1 of the water mixing tap, and these pipes 2a and 2b are connected to water supply and hot water supply pipes in the wall of the building. And fixed to the wall.

A handle 3 for hot water, a handle 4 for hot water, and a switching handle 5 are provided outside the main body 1, respectively, and the switching handle 5 is used to move to a water discharge pipe 6 side and a shower hose 7 side to a shower head (not shown). Can be switched. The water handle 3 is located at the right end of the main body 1, the hot water handle 4 is located at the upper center of the main body 1, and the switching handle 5 is located at the front center of the main body 1. It is offset to the right from the center.

FIG. 4 is a cutaway plan view taken along the line BB of FIG. 1, and FIG. 5 is a longitudinal sectional view taken along the line CC of FIG.

Inside the main body 1, there are provided a water supply chamber 1a communicating with the water leg pipe 2a, a hot water supply chamber communicating with the hot water leg pipe 2b, and a mixing chamber 1c communicating with the flow path to the water discharge pipe 6 or the hose 7 side. Are provided.

As shown in FIGS. 4 and 5, the water supply chamber 1a has a flow path having a rectangular cross section opened to the back side of the main body 1, and a valve hole 1d is formed in a wall facing the water handle 3 side, and the periphery thereof is opened. Is formed with a water valve seat 1e. Then, the water handle 3 connects the spindle 3a to the main body 1 so as to be movable in the axial direction by screw connection, and enables the valve body 3b provided at the tip of the spindle 3a to be connected to and separated from the water valve seat 1e. Thus, by the turning operation of the water handle 3, the flow rate of water flowing from the water supply chamber 1a to the mixing chamber 1c is set according to the valve opening between the valve body 3b and the water valve seat 1e.

In FIG. 5, a valve hole 1f for hot water is formed in a partition wall between the hot water supply chamber 1b and the mixing chamber 1c, and the upper surface thereof is formed as a hot water valve seat 1g. A drop-top valve 4 provided at the lower end of a spindle 4a which is screwed to the main body 1 and is movable in the axial direction.
b can be moved toward and away from the hot spring valve seat 1g. This allows
By rotating the hot water handle 4, the flow rate of hot water toward the mixing chamber 1c can be set similarly to the water side.

When the hot water supply chamber 1b is connected to an external water heater or the like, the hot water supply pressure becomes lower than that of the water supply side.
For this reason, there is a possibility that a backflow from the mixing chamber 1c to the hot water supply chamber 1b may occur. However, the backflow is prevented by dropping the valve body 4b and making it possible to maintain the closed valve by its weight to make it possible to close the valve. be able to. For this reason, compared with the case where a check valve is separately provided, the water flow resistance is also reduced.

In FIG. 3, the spindle 5a of the switching handle 5 is connected to the main body 1 by screw connection, and the valve body 5b provided at the tip thereof is located in the mixing chamber 1c. Then, the first valve seat 1h with which the valve element 5b comes and goes.
And a second valve seat 1i are provided at the start of the flow path of the connection flow path 1j between the water discharge pipe 6 and the connection pipe 7a to the shower hose 7 side, respectively. In the illustrated state, the valve element 5b is seated on the second valve seat 1i to close the flow path to the shower hose 7 side, and the mixed water is supplied to the water discharge pipe 6 side. When the switching handle 5 is turned to move the spindle 5 to the right in the figure, the first
The valve seat 1h is closed by the valve element 5b, and switching to water discharge from the shower side is performed.

The water handle 3 and the switching handle 5 have a substantially common cylindrical outer shell shape, and their axes are in a horizontal posture. Then, lever portions 3c, 5c protruding in the radial direction are provided on the peripheral surfaces of the handles 3, 5,
These levers 3c and 5c can be operated with a fingertip.

On the other hand, the hot water handle 4 is also columnar in shape in common with the water and switching handles 3, 5, but the hot water handle 4 has a triangular lever portion as shown in FIG. 4c is protruded and is different in appearance from the other handles 3,5. At the tip of the lever 4c, hemispherical points 4d are provided on both left and right sides as shown in FIGS. 2 and 4, so that a fingertip can be easily put on.

In the above configuration, the water handle 3 for determining the opening / closing of the flow path of water and the flow rate thereof is located at the right end of the main body 1 and its rotation axis is in the horizontal direction. The hot water handle 4 has a vertical rotation axis at the center of the upper surface of the main body 1. For this reason, since not only the directions of the water and hot water handles 3 and 4 but also the directions in which they are turned are completely different, there is no possibility that the water side and the hot water side will be mistaken even when groping.

Further, since the switching handle 5 is located at the center of the front of the main body 1 and its rotation axis is horizontal, the turning direction is different between the switching handles 5 and the handles 3 and 4 for hot water and hot water. Therefore, the operation of the switching handle 5 is not mistaken for the handles 3 and 4 for water or hot water.

As described above, since each of the handles 3 to 5 has a three-dimensional arrangement in which the axes around which the handles 3 to 5 form orthogonal space coordinates,
Once you learn how to use it, you can easily handle it without erroneous operation. In particular, since the shape difference between the hot water handle 4 and the other handles 3 and 5 is apparent due to the lever portion 4c and the point 4d, there is no confusion when the hot water supply operation is performed.

Here, as described in the section of the prior art, in a facility in which a hot water supply device is incorporated in a hot water supply pipe so that hot water which has been heated to an appropriate temperature in advance by the hot water supply device can be supplied to the main body 1.
The water handle 3 is rarely used, and the hot water handle 4
And only the switching handle 5 is operated. In this case, since the main body 1 of the hot and cold water mixing tap is usually mounted at a position where the line of sight of a user can be poured from above, the upper surface of the main body 1 is most noticeable, and the handle 4 for hot water provided here is used. Is convenient. In particular, as compared with the case where the handle for hot water is conventionally located on the left side of the main body, the hot water handle 4 which is located at the center of the main body 1 and has a different direction and shape from the water and switching handles 3, 5 By providing, it is possible to handle easily without erroneous operation.

According to the first aspect of the present invention, since one of the operation handles is provided on the upper surface side of the main body, it is easy to distinguish it from the other operation handle, and the operation handle on the upper surface side is frequently used. If so, the usability is improved.

Also, by dropping the valve body to make it a top type,
To prevent backflow.
The water flow resistance can be reduced as compared with the case where it is provided .
