Description

BACKGROUND OF THE INVENTION 1. 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 is a hot and cold water mixing apparatus of this type as shown in FIG.

FIG. 5 shows a conventional hot and cold water mixing apparatus. The hot water and water supplied through the hot water pipe 1 and the water pipe 2 are connected to the connecting tube 3,
It is introduced into the mixing stopper body 7 via the water supply connection port 5 and the hot water supply connection port 6 via 4. The mixing stopper body 7 is provided with a temperature control knob 8 and a hot water discharge amount setting knob 9. Also the mixing stopper body 7
Is a knob for switching the flow path to the shower hose 10 and the discharge pipe 11.
Twelve are provided. The discharge pipe 11 is provided so as to be rotatable left and right around the mounting portion 13.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the above-described configuration, the temperature adjusting knob 8, the hot water amount setting knob 9, the flow path switching knob 12 between the shower hose 10 and the discharge pipe 11, which are provided in the mixing stopper body 7, The attachment portion 13 of the discharge pipe 11 or the like causes an abnormal phenomenon such as water leakage due to deterioration of packing or malfunction when it is used for many years, and needs to be repaired / replaced. However, since the mixer tap body 7 is directly connected to the hot water supply connection port 5 and the hot water supply connection port 6 from the hot water pipe 1 and the water pipe 2 via the connection tubes 3 and 4, when the supply of hot water is interrupted, It cannot be shut off unless the home water source valve (not shown) is closed.
Therefore, while finding an anomaly and requesting a repair company to spend on repair / replacement, there was a problem that hot water could not be used and no housework such as bath, cooking, and laundry could be performed.

The present invention is to solve the above problems,
Provided is a hot and cold water mixing device that can use hot and cold water even if the mixing stopper body becomes unusable due to some abnormality.

Means for Solving the Problems To solve the above problems, the hot and cold water mixing device of the present invention is
A hot water / water mixing faucet having a water supply connection port, a hot water supply connection port, and a discharge water connection port, and a flow path switching valve separately provided on the primary side of the water supply connection port and the hot water supply connection port, respectively. A valve is used to switch between hot water supply and hot water supply to the hot and cold water mixing faucet side flow path and the bypass side flow path that directly flows to the water discharge pipe.

Operation With the above configuration, when the hot and cold water mixing faucet becomes unusable due to some abnormality, hot water can be used by operating the flow path switching valve and switching the water supply and hot water supply paths to the bypass side flow path. it can.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings. The same components as those in the conventional example are designated by the same reference numerals, and detailed description thereof will be omitted. In FIG. 1 and FIG. 2, hot water is introduced into the flow passage switching valve 14 from the hot water pipe 1 and the water pipe 2, respectively, and water is stopped by operating the flow passage switching handle 15 (state of FIG. 2 (a)). , Or hot and cold water mixing faucet 16 side flow path 17
(State of FIG. 2 (b)), or water side bypass flow path 18 ・
It is switched to the hot water bypass passage 19 (state of FIG. 2 (c)).

During normal use, the hot water flow path is switched to the hot and cold water mixing faucet 16 side by setting the flow path switching valve 14 to the state shown in FIG. 2 (b). The switched hot and cold water is introduced into the hot and cold water mixed tap 16 through the hot water supply connection port 5 and the hot water supply connection port 6. Although not shown, the introduced hot and cold water is mixed at an appropriate temperature by the mixing valve of the hot and cold water mixing section in the hot and cold water mixing faucet 16 and is introduced into the special four-way nipple 21 through the water discharge connection port 20 with a check function and through the water discharge pipe 22. Spout
26 (see FIG. 3 (a)).

When the hot and cold water mixing faucet 16 becomes unusable due to some abnormality, the water can be stopped by setting the flow path switching valve 14 to the state shown in FIG. 2 (a). Therefore, the water can be easily stopped in the bathroom, and the other cases will not be adversely affected.

Further, when hot water is desired to be used even in an abnormal condition, the hot water flow path is switched to the water / hot water bypass flow paths 18, 19 by setting the flow path switching valve 14 to the state shown in FIG. 2 (c). By doing so, hot water flows into the water and hot water bypass passages 18 and 19 and is introduced into the special four-way nipples 21 and supplied from the water discharge port 26 through the water discharge pipe 22. At that time, by changing the opening / closing degree of the flow path switching handle 15, it is possible to change the amount of hot water flowing in the water and hot water bypass passages 18, 19.

As a result, the mixing ratio of hot and cold water is changed in the special four-way nipple 21, and the hot water is supplied at an appropriate temperature without impairing the usability of hot water.

In addition, from the water and hot water bypass passages 18, 19
Backflow to 6 is prevented by the water discharge connection port 20 with a check function.

3 and 4 each show an example of installation of the hot and cold water mixing apparatus of the present invention, and FIG. 3 (a) shows a state in which the hot and cold water mixing apparatus of the present invention is installed in the apron 24 of the bathroom 23. It is a perspective view shown, (b) is the same side view. FIG. 4 (a) is a perspective view showing a state where the hot and cold water mixing apparatus of the present invention is installed on the outer wall 25 of the bathroom 23, and FIG. 4 (b) is a side view of the same. Since the flow path switching valve 14 is used in an emergency, the flow path switching valve 14 is installed so that it is not easily noticed, and if it is installed inside the apron 24 of the bathroom 23 so that it can be easily operated in the event of an abnormality,
The flow path switching handle 15 is seen in the lower part of the inside of 24.

Further, when the outer wall 25 of the bathroom 23 is installed, only the flow path switching handle 15 is seen inside the bathroom 23.

In this way, it can be simply installed without going inside or outside the bathroom 23, so that it has an effect of being unobtrusive and being easy to operate in the case of an abnormality.

Effects of the Invention As described above, according to the hot and cold water mixing apparatus of the present invention, the following effects can be obtained.

(1) Even if the hot and cold water mixing faucet becomes unusable due to some abnormality, the water and hot water can be used without problems in the kitchen as well as in the bathroom.

(2) Even if water leaks from the main body of the hot and cold water mixing faucet or the pipe connection port, or if there is a poor water stoppage, the water can be stopped easily without adversely affecting other places.
