Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a hot and cold water device that can switch between a cold water production function and a hot water production function.

BACKGROUND TECHNOLOGY As shown in FIG. 2, a conventional cold/hot water system of this type includes a refrigeration cycle 5 including a compressor 1, a condenser 2, a capillary 3, and an evaporator 4. It was wrapped around the outer periphery and fixed. A water supply pipe 8 was provided on the upper side plate 7 of the tank 6, and a water outlet pipe 9 was similarly provided extending from the upper side plate 7 to near the lower side plate 10. A heater 11 for producing hot water was provided near the lower plate 10. When the refrigeration cycle 5 operates, the water that enters the tank 6 from the water supply pipe 5 is cooled by the evaporator 4 and becomes cold water, and on the other hand, when the electric heater 11 operates, it is heated and becomes hot water. Ta.

Problems to be Solved by the Invention However, in the above configuration, when hot water is produced by the electric heater 11, the heated hot water has a low specific gravity and rises to become hot water from the upper part of the tank 6. However, when hot water is taken out, the water outlet pipe 9 is taken out from the lower part of the tank 6, so there is a problem in that hot water cannot be taken out.

The present invention solves such conventional problems,
The purpose is to efficiently take out cold water while maintaining temperature stratification when cold water is created in the same tank, and to take out hot water efficiently while maintaining temperature stratification when hot water is created.

Means for Solving the Problems In order to solve the above-mentioned problems, the cold/hot water device of the present invention provides a distribution channel that switches between a water supply pipe and a water outlet pipe, and between a water pipe and a faucet pipe when producing cold water and when producing hot water. It is equipped with a switching valve.

Effects According to the present invention, with the above-described configuration, when hot water is produced, by switching the distribution channel switching valve to the hot water side, the water pipe is connected to the outlet pipe, the faucet pipe is connected to the water supply pipe, and the hot water accumulated in the upper part of the tank is connected to the water supply pipe. The water flows from the water supply pipe to the faucet pipe, allowing for efficient hot water dispensing while maintaining temperature stratification.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings. Note that the same parts as in FIG. 2 are given the same numbers.

In FIG. 1, reference numeral 12 denotes a distribution channel switching valve to which a water pipe 13, a water outlet pipe 14, a water supply pipe 8, and a water outlet pipe 9 are connected.

In the above configuration, when hot water is being produced, the water pipe 13 and the water outlet pipe 9 are connected by switching the distribution channel switching valve 12, and the supply water flows into the tank 6 from below. Further, the water supply pipe 8 is connected to the end pipe 14 and flows out from above the tank 6 . In addition, when making cold water, by switching the distribution channel switching valve 12, the water pipe 13 and the water supply pipe 8, and the water outlet pipe 9 and the faucet pipe 14 are connected, and the supply water flows from the upper part of the tank 6 and the lower part of the tank 6. flows out from Therefore, there is an effect that both cold water and hot water can be extracted efficiently by maintaining temperature stratification both when creating cold water and when creating hot water.

Effects of the Invention As described above, according to the cold/hot water device of the present invention,
A distribution channel switching valve is installed, and when creating cold water, connect the water pipe and the water supply pipe, and the water outlet pipe and the faucet pipe, so that the water flows in from the top of the tank and flows out from the bottom of the tank, and when creating hot water, the water pipe and the water pipe, The water supply pipe and faucet pipe are connected, and the water flows in from the bottom of the tank and flows out from the top of the tank, which solves the problem of not being able to maintain temperature stratification when creating hot water and causing low-temperature water to come out instead of hot water. This has the advantage of being able to maintain temperature stratification during the production of hot water and allowing for efficient extraction.
