Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mixed faucet facility, and more particularly to a mixed faucet facility capable of discharging hot water whose temperature has been adjusted to an appropriate temperature even when only hot water is discharged.

[0002]

2. Description of the Related Art In the case of a conventional single-lever type mixed faucet or a two-handle type mixed faucet attached to a washbasin, for example, when the hot water side is fully opened and only hot water is discharged, 60
Hot water above ℃ is discharged.

Therefore, for example, in a facility used by the elderly, when the hot water side is fully opened and only hot water is discharged, hot water that has been preliminarily adjusted to an appropriate temperature of about 35 to 45 ° C. can be discharged to prevent burns. There was a demand for safe use of the mixed faucet.

Conventionally, a mixed faucet facility as shown in FIGS. 3 and 4 has been used to realize this.
In the mixed faucet equipment shown in FIG. 3, the temperature control part 21 is attached and fixed to the rear wall of the washbasin 2 while being supported by both the hot water supply pipe 7 and the water supply pipe 8A via a pair of crank legs 22. ing.

On the other hand, in the mixed faucet equipment shown in FIG. 4, the temperature control part 24 is attached and fixed to the wall on the rear side of the washbasin 2 while being supported by the hot water supply pipe 7 via the pipe connection part 25.

[0006]

However, in the case of the conventional mixed faucet equipment, since it is necessary to fix the temperature control part by both the hot water source pipe 7 and the hot water source pipe 8A, or only the hot water source pipe 7. There is a restriction that the mounting position of the temperature control unit is near the hot water supply pipe 7 or the water supply pipe 8A. When there is a temperature control part near the hot water supply pipe 7, when the temperature is adjusted in a place under the basin 2 which is difficult to see, the pipe connection part 25 of the hot water supply pipe 7 is mistakenly used.
There was a risk of getting burned by touching the crank legs 22.
Also, if the temperature control unit main body is made of a metal material, the surface temperature becomes hot, and there is a possibility of accidentally touching the metal surface and getting burned when adjusting the temperature in a place under the washbasin 2 that is difficult to see. there were.

Further, in any of the mixed faucet equipment, the temperature control part is supported by both the hot water supply source pipe 7 and the water supply source pipe 8A or only the hot water supply source pipe 7 via the crank leg 22 or the pipe connection part 25. Since the basin 2 is attached and fixed to the rear wall of the basin 2 in this state, the projection of the wall toward the front side becomes large, and it may be difficult to secure a large space under the basin.

[0008]

Therefore, the present invention has been devised in order to solve the above problems in the present invention. According to the first aspect of the invention, hot water is mixed with hot water in the temperature control unit to supply the temperature-controlled water having an appropriate temperature in advance to the hot water inlet of the mixing tap, and the hot water side of the mixing tap is fully opened to remove only hot water. In the mixed faucet equipment configured so that hot water does not come out when water is spouted, a casing having a temperature control part is fixed to a wall on the rear side of the mixed faucet equipment. Attach the casing to an arbitrary position that does not interfere with drainage pipes, water stopcocks, water taps with branches, etc. below the washbasin, and fix the temperature control part to the casing to supply water to the casing. Since the main pipe and the water supply pipe can be arranged regardless of the positions, it is possible to easily cope with the case where the temperature control unit is added to the existing mixing faucet. In addition, since the temperature control unit can be arranged at a position away from the hot water supply pipe, it is possible to prevent accidental burns when touching the pipe connection portion of the hot water supply pipe when adjusting the temperature. Furthermore, since the casing is attached to the wall on the rear side of the washbasin, there is an advantage that the projection of the wall to the front side can be suppressed and a large space can be secured.

According to a second aspect of the present invention, in the mixed faucet facility according to the first aspect, the temperature control section main body is formed of resin. By forming the temperature control unit body with resin instead of the conventional metal material, it is possible to avoid the surface temperature of the temperature control unit body from rising, so when performing temperature control etc. under the washbasin it is difficult to see. Even if you accidentally touch the temperature control unit body, you can prevent burns. In addition, since the temperature control part main body is made of resin, the weight can be reduced, and the temperature control part can be easily supported on the wall.
