Abstract

PURPOSE:To supply hot-water into a bathtub at all times even after using hot- water at a washing place by a method wherein the hot-water supplier is constituted of a hot-water supplying machine, a mixing valve and a mixing cock and the water discharging port of the mixing cock is attached pivotably so as to be located at the side of the bathtub at all times and capable of being returned automatically. CONSTITUTION:The hot-water supplier M is consisting of the hot-water supplying machine A, the mixing valve B and the mixing cock C. The hot-water supplying machine A is communicated with the mixing cock C through a water feeding pipeline 17 and a hot-water supplying pipeline 16 while the mixing valve B is provided on the way of both pipelines. A water discharging pipe 18 is provided pivotably and a torsion spring (f) is attached so as to be wound around the base end of the pipe 18 which the water discharging pipe 18 is energized toward the side of the bathtub at all time to locate the water discharging cock at the side of the bathtub. When the water discharging pipe 9 is used at the side of the washing place, it is pivoted by hand toward the side of the washing place and, after using, it is returned to and located at the side of the bathtub by the spring by releasing the hand from the pipe 18.

Description

[Detailed description of the invention] (Industrial application field) This application relates to an invention of a water heater.

(Conventional technology and its problems) Conventional water heaters supply mixed water according to a preset set temperature, or manually rotate the water valve or hot water valve of a mixer faucet to produce any mixed water. When installing these in a bathroom, etc., install two separate mixing faucets for each.
i! I used it once.

Therefore, there was a problem in that it not only took time and effort to arrange the mixing taps, but also increased costs.

Therefore, it is conceivable to supply a set constant-temperature hot water and mixed water by manual operation of a water valve and a hot water valve through a single mixing faucet.

However, if the spout pipe of the mixing faucet is made rotatable so that it can be used for both the bathtub and the wash area, after the spout pipe is used toward the wash area, it is not returned to the bathtub side and is left in the same state so that it can be used from outside. If hot water is automatically supplied based on a command, there is a risk that the hot water will not be supplied into the bathtub and hot water, fuel, etc. will be wasted.

(Technical Problem to be Solved by the Invention) The technical problem to be solved by the present invention is to supply hot water using a single mixer faucet that supplies fixed-temperature hot water, a water valve, and mixed water by manual operation of the hot water valve. To provide a device in which hot water is always supplied to a bathtub side even after a rotatable bathtub and a water spout pipe serving as a washing area are used on the washing area side.

(Technical means for achieving the technical problem) The technical means of the present invention for achieving the above technical problem consists of a water heater, a mixing valve, and a mixing faucet, and the mixing valve is a water heater and a water heater. The mixing faucet is equipped with a water valve, a hot water valve, and a mixing flow path, and connects the primary side of these water valves to the secondary side of the water supply source. On the side, the primary side of the hot water valve is connected to the water heater, and the mixing flow path is connected to the secondary side of the mixing valve, and the water discharge pipe of the mixing faucet is rotatably attached and always located on the bathtub side. , and to enable automatic recovery.

(Function) Set tl by external command! When the temperature is set, the constant temperature hot water set by the command is mixed by the mixing valve and water is discharged from the water discharge pipe.

Further, by manually rotating the water valve and the hot water valve of the mixing faucet, mixed hot water at a desired temperature is mixed in the mixing channel and water is discharged from the water spouting pipe.

When the water spout pipe is used on the washing area side, the water spout pipe is rotated by hand, and when the hand is released after use, the water spout pipe automatically returns to the bathtub side and is always located on the bathtub side.

(Effect of the invention) Since the present invention is constructed as described above, it has the following effects.

■ Even if the spout pipe is used in the washing area, it will automatically return to the bathtub side after use, and since it is always located on the bathtub side, even if hot water is automatically supplied by an external command, hot water will still be supplied to the bathtub.
It is possible to prevent wasteful use of air purification, fuel, etc.

■ There is no need to separately arrange a mixer faucet that supplies fixed-temperature water according to a preset temperature, a water valve for the mixer faucet, and a mixer faucet that supplies any mixed water by manually rotating one valve. , constant temperature hot water set with one mixer faucet and water valve,
Mixed water can be supplied by manual operation of the hot water valve, so there is no need for time and effort for distribution, and it is also economically inexpensive.
