Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a hot water supply device and a hot water mixing device provided at a terminal of the water supply device.

2. Description of the Related Art Conventionally, there has been a hot water mixing device 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 faucet main body 7 through the connecting pipes 3 and 4, and through the water supply connection port 5 and the hot water supply connection port 6. The mixing faucet main body 7 is provided with a temperature control knob 8. The mixing faucet body 7 also includes a shower hose 9, a discharge pipe 10, and a shower hose 9.
and a flow path switching knob 11 to the discharge pipe 1°. The discharge pipe 1o is mounted so as to be rotatable left and right around a mounting portion 12.

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

(1) The mixing faucet main body 7 is attached to the bathroom wall via the connecting pipes 3 and 4, and since the connecting pipes 3 and 4 are located at the rear of the mixing faucet main body 7, the mixing faucet main body 7 is attached to the wall surface. If the user accidentally falls over, the user may hit his/her body or head with the mixing tap body 7 or the tip of the discharge pipe 1o protruding from the mixing tap body 7, causing injury. There was a lot to do.

(2) Since the discharge pipe 1o could only be rotated left and right, the discharge position could not be adjusted in the front-back direction.

(3) The hot water mixing faucet 7 has a shower hose 9 and a discharge pipe 1.
Bathtub 1 has only two switching functions, bathtub 1 and 0.
If hot water and cold water are to be supplied separately to the bathtubs 3 and 3, a bathtub mixer faucet 14 as shown in Fig. 6 and separate piping work for the hot water and water pipes 1 and 2 are required, which is extremely expensive. becomes.

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

Means for Solving the Problems In order to solve the above problems, the hot water mixing device of the present invention has the following features:
The valve box includes a water supply connection port, a hot water supply connection port, and a plurality of water discharge connection ports, a switching valve that switches water discharge to the plurality of water discharge connection ports, and a hot water mixing valve that changes the temperature of the discharge water. and the water supply connection port is located at the lower side of the valve box, the hot water supply connection port is located opposite to the water supply connection port, and one of the plurality of water discharge connection ports is located at the front of the valve box, The water spout connection port is located on the top surface of the valve box.

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

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. Note that the same components as those in the conventional example are given the same reference numerals, and detailed explanation thereof will be omitted. Figure 1.

In FIG. 2, hot water and water are supplied through the hot water pipe 1 and the water pipe 2 through the water supply connection port 6 located at the lower side of the valve box 15.
and is introduced into the valve box 15 via the hot water supply connection port 6. The introduced water and hot water are introduced into the hot water mixing section 17 through a strainer 16 that is detachably provided on the bottom of the valve box 16, and the mixing valve 1
8 to mix at an appropriate temperature. The mixed hot water is switched to the bathtub path 2o or the washing area/shower path 21 by the first switching valve 19. The hot water switched to the bathtub path 20 is sent to the bathtub water outlet connection port 22. Bathtub piping 2
Water is discharged after 3 steps.

In addition, the hot water switched to the washing area/shower path 21 is transferred to the washing area path 2i and the shower path 2 by the second switching valve 24.
θ and the washing area water spout connection port 27 or the shower water spout connection port 28. Water is discharged through the shower pipe 29.

The mixing valve 18 and the first and second switching valves 19.24 are each driven by a driving motor 30. motor 3
The drive control of o is performed by signals from a separate control section and an operation section (not shown).

3 and 4 show a general installation example of the hot water mixing device of the present invention, and FIG. 3 shows one installed inside the apron 32 of a bathroom 31. )) shows the installation side view. FIG. 4 shows an example in which the device is installed on an outer wall 33 of a bathroom 31, where (,) shows a schematic configuration diagram of the installation, and (b) shows a side view of the installation.

As shown in the figure, the bathroom 31 includes a washing area spout 34°, a bathtub spout 36. Since only the shower spout 36 is exposed, the space in the bathroom 31 can be used effectively, and the body or head will not be injured by hitting the hot water mixing device 36. Furthermore, since the hot water piping is not exposed inside the bathroom 31, there is no fear of burns.

Also, water supply connection port 5. The hot water supply connection port 6 is located at the lower side of the valve box 16, and the bathtub water outlet connection port 22. Shower water connection port 2
8 is provided on the top surface of the valve box 16, making it easy to connect the pipes, and the depth of the valve box 16 can be small, and the water discharge pipes 23 and 29 of the bathtub and shower have the same configuration. Shower pipe 23 to shower 1111
It is also possible to pipe the water discharge pipe 29 to the bathtub side, increasing the degree of freedom in installing the hot water mixing device.

Furthermore, since the strainer 16 is detachably provided at the bottom of the valve box 16, the strainer 16 can be easily cleaned.

In particular, when the hot water mixing device is located inside the apron 32 in the bathroom 31, the strainer 16 can be cleaned without removing the apron 32 each time. In addition, each spout can be selectively provided in a desired location and as desired, improving usability.

Effects of the Invention As described above, in the hot water mixing device of the present invention, the piping connections to the hot water mixing device are located on the left, right and upper sides of the lower part, so the depth dimension of the hot water mixing device is reduced and space saving can be achieved. It is also possible to install the device inside the bathroom apron or inside the exterior wall of the bathroom.
