Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a hot water supply system that is capable of dispensing hot water at a desired temperature to a plurality of locations.

(Prior Art) In recent years, even ordinary households have come to be equipped with heat source devices and have piping installed in multiple locations to supply hot water.

Such a hot water supply system, for example, as shown in Figure 3, is one in which hot water supply pipes are connected to four locations from one heat source device, the hot water temperature is set at one of the locations, and hot water is supplied at each location. In addition, as shown in Figure 4, one heat source is connected to hot water supply piping to four locations, and each location is equipped with a mixing tap for adjusting the hot water temperature, so that hot water at the desired temperature can be obtained from each location. I can give an example of what has been done.

However, among the hot water supply systems mentioned above,
Once the hot water supply temperature is set at one location, hot water at that temperature is also dispensed at other locations, making it difficult to obtain hot water at the desired temperature.

On the other hand, according to ■, even if it is possible to obtain hot water with different temperatures at each location, a mixing faucet is required at each location, and additional plumbing work is required for the water supply pipes, which increases the cost. It will take a while.

Therefore, in order to solve the above-mentioned problems, a thermomixing valve has been devised as shown in FIGS. 5 and 6 instead of a mixing tap for adjusting the temperature of hot water. This thermomixing valve has the function of dispensing hot water at a desired temperature by adjusting the mixing ratio of hot water and cold water in advance, and also uses a thermal expansion member to detect fluctuations in the hot water after mixing. , the mixing ratio of hot water and cold water is automatically adjusted to suppress such fluctuations.

(Problem to be solved by the invention) However, even if the above-mentioned thermomixing valve is applied, - When the valve is stopped and then opened again, the thermal expansion member cannot follow the temperature, and the temperature instantaneously becomes higher than the set temperature. Hot water and cold water will be dispensed (see Figure 5).

Furthermore, if the heat source device is an instantaneous type, the cold water caused by the ignition delay will upset the balance of the hot water mixing ratio of the thermomixing valve, causing the water temperature to fluctuate (see Figure 6).

The present invention has been made in view of these problems, and allows hot water at a stable temperature to be supplied to multiple locations by adjusting the temperature to the desired temperature, while simplifying piping work. The purpose is to provide a possible hot water system.

(Means for Solving the Problems) In order to solve the above problems, the present invention connects a hot water and cold water mixing section to a heat source device via a water pipe and a hot water pipe, and the mixing section includes a plurality of hot water and cold water mixing sections. A hot water mixing means is provided, and a water pipe and a hot water pipe are branch-connected to the hot water mixing means, and each of the hot water mixing means adjusts the mixing ratio of hot water and cold water to produce hot water at a desired temperature. It is equipped with a remote control means for obtaining the information.

(Function) Hot water from the heat source reaches the mixing section via hot water piping,
Introduced into hot water mixing means. The hot water mixing means is dedicated to each hot water supply location, and the mixing ratio of hot water and cold water is adjusted at each hot water supply location in order to obtain desired hot water.

Therefore, hot water at a desired temperature is supplied to each hot water supply point. At this time, as the mixed hot water flows from the hot water mixing means through the hot water piping leading to each hot water supply point, the hot water becomes more evenly mixed, and hot water with a substantially constant temperature can be obtained. Moreover, since only the hot water piping needs to be installed to the hot water supply location, the piping work is simplified.

(Example) Next, a hot water supply system according to the present invention will be described below by giving one example and referring to the attached drawings.

In FIG. 1, reference numerals ] indicate a hot water supply system, and this hot water supply system 1 is constructed by connecting a hot water and cold water mixing section 5 to a heat source 2 via a water pipe 3 and a hot water pipe 4.

As shown in FIG. 2, the mixing section 5 includes a plurality of hot water mixing means, that is, thermomixing valves 6a and 6b.
, 6c, and 6d are arranged, and a water pipe 3 and a hot water pipe 4 are branch-connected to these thermomixing valves 6a to 6d.

The thermomixing valves 6a to 6d are formed with water introduction lowers a to 7d for introducing water from the water pipe 3, hot water inlets 8a to 8d for introducing hot water from the heat source device 2 from the hot water pipe 4, and hot water inlets 9a to 6d. 9d is formed. In addition, thermo mixing valves 6a to 6
d is equipped with a hot water mixing adjustment mechanism] Oa or lod for setting and adjusting the mixing ratio of hot water and cold water in advance, and a thermal expansion member (for example, a wax member) not shown.

A to IOd are readjusted.

Next, hot water supply pipes 11a, llb, llc, and 11d are installed to supply mixed hot water from the hot water ports 9a to 9d of the thermomixing valves 6a to 6d to the hot water supply locations. In addition, at each hot water supply point, a hot water mixing adjustment mechanism 10 of the thermomixing valves 6a to 6d is provided.

a, +2b, +2c, and 12d are arranged, and by operating the remote control means 12a to +26, the hot water mixing adjustment mechanisms 10a to 1ocl are operated to adjust the mixing ratio of hot water and cold water to a desired value. You can get hot water at the same temperature as the hot water.

The hot water supply system 1 according to the present invention is configured as described above, and its operation will be explained next.

Hot water from the heat source device 2 reaches the mixing section 5 via the hot water pipe 4, and is introduced into the thermomixing valves 6a to 6d. The thermomixing valves 6a to 6d are operated by the hot water mixing adjustment mechanism 10 by operating any one of the remote control means 12a to 12d at the hot water supply point.
By operating either a or lod, the mixing ratio of hot water and cold water is adjusted in advance to obtain hot water at a desired temperature. Therefore, the hot water is mixed into hot water at the thermomixing valves 6a to 6d based on the set mixing ratio, and the hot water is connected to each hot water supply point by a hot water pipe.
Hot water at a desired temperature is supplied via 1a to lid. At that time, the thermo-mixing valves 6a to 6d
Even if there is a fluctuation in the mixed hot water, the mixing ratio is automatically adjusted by the thermal expansion member to suppress the fluctuation, and the hot water supply pipes 11a to lld leading to each hot water supply point are
As the hot water flows through the mixed hot water, the mixing of the hot water and cold water is further promoted, resulting in mixed hot water having a substantially constant hot water temperature with suppressed hot water temperature fluctuations.

In addition, as mentioned above, the hot water supply system 1 according to the present invention
Since only the hot water supply pipes 11a to lid are connected to each hot water supply point, there is no need to provide water piping as in the conventional case, and the piping work can be simplified.
