Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water supply apparatus and a hot water mixing apparatus provided at the end of a water supply apparatus.

2. Description of the Related Art Conventionally, there is a hot and cold water mixing apparatus of this type as shown in FIG.

In FIG. 5, hot water and water supplied through the hot water pipe 1 and the water pipe 2 are introduced into the mixing stopper main body 7 through the connection tubes 3 and 4 and the water supply connection port 5 and the hot water supply connection port 6. The mixing stopper body 7 is provided with a temperature control knob 8. Further, the mixing tap body 7 is provided with a shower hoe 9, a discharge pipe 10, a shower hose 9 and a flow passage switching knob 11 to the discharge pipe 10. The discharge pipe 10 is provided so as to be rotatable left and right around the mounting portion 12.

Problems to be Solved by the Invention However, the configuration as described above has the following problems.

(1) The mixing tap body 7 is attached to the bathroom wall through the connecting tubes 3 and 4, and since the connecting tubes 3 and 4 are located behind the entire mixing tap 7, the mixing tap body 7 is a wall surface. If it is an obstacle, and the user accidentally falls over, the user hits the body or the head on the mixing stopper 7 with the tip of the discharge pipe 10 protruding from the mixing stopper main body 7, I was often injured.

(2) Since the discharge pipe 10 can only rotate to the left and right, the discharge position in the front-back direction could not be adjusted.

(3) The hot and cold water mixing tap 7 has a shower hose 9 and a discharge pipe.
Bathtub that does not have a switching function in 2 places with 10 13
When supplying hot water and water individually to the bathtub, a hot and cold water mixing tap 14 for bathtub and individual hot water and water pipes as shown in FIG.
It requires 1 and 2 plumbing work, which is very expensive.

The present invention solves the above problems, and an object of the present invention is to provide a hot and cold water mixing apparatus which is less dangerous and has a high degree of freedom in the discharge direction and shape.

Means for Solving the Problems In order to solve the above problems, a hot and cold water mixing apparatus of the present invention includes a valve box having a water supply connection port, a hot water supply connection port, and three or more water discharge connection ports, and the valve. It has a switching valve for switching the water discharge to the three or more water discharge connection ports located in the box, and a hot water mixing valve for changing the water discharge temperature, and the water supply connection port is located on the lower side of the valve box on the lateral side. And, the hot water supply connection port is located on the surface facing the water supply connection port, and one of the three or more water discharge connection ports is located on the front surface of the valve box, and the water discharge connection port is
The structure is located on the upper surface of the valve box.

Operation With the above configuration, the hot and cold water mixing device can be installed on the outer wall of the bathroom and the apron of the bathroom, and only the discharge pipe is exposed to the inside of the bathroom.

Example Hereinafter, one example of the present invention will be described with reference to the accompanying drawings. The same components as those of the conventional example are designated by the same reference numerals,
Detailed description thereof will be omitted. 1 and 2,
The hot water and water supplied via the hot water pipe 1 and the water pipe 2 are
It is introduced into the valve box 15 through the water supply connection port 5 and the hot water supply connection port 6 located on the lower side of the side. The introduced water and hot water is a valve box
The mixture is introduced into the hot and cold water mixing section 17 through a strainer 16 which is detachably provided on the bottom surface of 15 and mixed at an appropriate temperature by a mixing valve 18. The mixed hot and cold water is switched to the bathtub path 20 or the washing / shower path 21 by the first switching valve 19. The hot and cold water switched to the bathtub path 20 is discharged through the bathtub water discharge connection port 22 and the bathtub pipe 23.

Further, the hot water switched to the washing place / shower route 21 is switched to the washing place route 25 and the shower route 25 by the second switching valve 24 and discharged through the washing place water discharge connection port 27, or the shower water discharge connection port 28, and the shower pipe 29. To be done.

The mixing valve 18 and the first and second switching valves 19 and 24 are each driven by a driving motor 30. The drive control of the motor 30 is separately controlled by signals from a control unit and an operation unit (not shown).

FIGS. 3 and 4 show an example of installation of the hot and cold water mixing apparatus of the present invention. FIG. 3 shows the installation in the apron 32 of the bathroom 31, and FIG. b) is shown in side view of installation. FIG. 4 shows an example of installation on the outer wall 33 of the bathroom 31, where (a) is a schematic configuration diagram and (b) is a side view of installation.

As shown in the figure, only the washroom spout 34, the bathtub spout 35, and the shower spout 36 are exposed in the bathroom 31, so that the space in the bathroom 31 can be effectively used and the body and head of the hot and cold water mixing device 36 can be used. No more hitting the part and getting injured. Further, since the hot water pipe portion is not exposed in the bathroom 31, there is no risk of burns.

As shown in FIGS. 2 and 4, the water supply connection port 5 and the hot water supply connection line 6 are located on the lower side of the valve box 15, and the bathtub water discharge connection port 22 and the shower water discharge connection port 28 are front, rear, left and right of the valve box 15. Since it is installed on the upper surface of the valve box 15 with a certain interval in the direction, it is easy to connect the piping, and the depth of the valve box 15 can be small, and the water discharge piping for the bathtub and the shower 2
Since 3, 29 have the same configuration as each other, it is possible to connect the water discharge pipe 23 to the shower side and the water discharge pipe 29 to the bathtub side, which increases the degree of freedom of installation of the hot and cold water mixing device.

Further, since the strainer 16 is detachably provided in the lower portion of the valve box 15, the strainer 16 can be easily cleaned. In particular, when the hot and cold water mixing device is in the apron 32 in the bathroom 31, the strainer 16 can be cleaned without removing the apron 32. In addition, since each spout can be selected and provided in a place where it is desired to be used, usability is improved.

Effects of the Invention As described above, the hot and cold water mixing apparatus of the present invention has the pipe connections to the hot and cold water mixing apparatus at the lower left and right and above, so the depth dimension of the hot and cold water mixing apparatus can be reduced and space can be saved. It is also possible to install the device inside the apron of the bathroom or inside the outer wall of the bathroom.
