Field of the Invention The present invention relates to a boiler in which water supplied at a predetermined pressure is adjusted by a pressure reducing valve interposed on a water source side and boiled into hot water of a predetermined temperature, and the hot water is supplied from a hot water supply unit to a supply unit. The present invention relates to a hot and cold water supply system for a water heater.

Description of the Related Art In general, in a hot water supply system, a hot water supply / water supply pipe line is provided between a hot water supply unit in which a water heater is installed and a hot water supply place provided as a supply unit such as a bathroom or a washroom. The hot water supplied by the water heater is supplied through this pipe line so that hot water can be collected from each of the hot water supply locations.

水手段として不可欠な減圧弁が設けられている。In addition, as a means for supplying water to the water heater and hot water supply, when a hot water supply faucet provided at an end of a piping at a hot water supply location is opened, water is supplied from a water source into a tank of the water heater. A so-called stop-push-up type in which hot water boiled in this tank is pushed up and hot water is collected is adopted. In addition, the water supply pipe that serves as the water source for the tank is indispensable as a low-pressure water supply means that reduces the water supply pressure when the water source is tap water to a constant pressure and prevents the high water pressure from the water supply from being applied to the tank. A simple pressure reducing valve is provided.

用するような場合に火傷の危険性がある。[0005] On the other hand, a hot tap water boiled by a water heater is taken immediately below a hot water tap provided at the hot water supply location, and mixed with hot water at a desired temperature by mixing water with the hot water. It is common to employ a well-known hot-water mixer tap that is manually adjusted so that it can be varied according to its intended use. In such a case, a water supply path is also necessary at the hot water supply place, but if tap water is introduced and supplied directly below the hot water mixer tap using the existing pipe, if the tap water pressure as a water source fluctuates, Since there is no means for absorbing and adjusting this, the set mixing balance between the supplied tap water and the high-temperature hot water supplied from the tank is disrupted, and the temperature of the hot water to be collected is suddenly changed. There is a danger of burns when hot water is supplied from the tap to the shower.

もに配管設置される。In order to prevent such a problem and to eliminate other problems caused by a sudden change in hot water temperature, the water supplied from a water source commonly used with a water heater in a hot water supply unit separated from a hot water supply location is adjusted to a predetermined water pressure. The secondary water supply channel of the pressure reducing valve is branched and used as a water source on the supply unit side, and between the hot water supply unit side and the supply unit side, a water supply pipeline is installed along with the hot water supply pipeline from the water heater. You.

もなる。As described above, conventionally, since at least two pipe lines are required between a hot water supply unit and a hot water supply place serving as a supply unit, high-temperature hot water and water are both used. The flow or stop is always performed in a state in which the pipe is always filled, and loss of heat energy radiated from the hot water supply pipe in which the high-temperature hot water flows is liable to occur. In particular,
If the distance between the hot water supply unit and the supply unit is long, the amount of hot water remaining in the pipe line due to the hot water supply is large, so that the boiling water in the tank is wastefully consumed.

する）の温度差が生じる。This phenomenon is the biggest drawback of the first push-up type. For example, when hot water is supplied from a water heater and mixed hot water at a temperature (approximately 43 ° C.) suitable for bathing is collected using the above hot water mixer tap or the like. Hot water (85 ° C.) heated to a high temperature is always used as hot water supplied from a water heater. Then, the hot water and the tap water supplied from the water source are mixed and adjusted at an appropriate ratio, so that the hot water is supplied to the bathtub, which is a hot water supply place, only as appropriate hot water. The hot water, which has always been heated to a high temperature, flows directly in relation to the hot water supply operation regardless of the final hot water temperature, and after the hot water supply operation has been completed, Also, since the hot water extruded from the tank is left as it is, a temperature difference of about 50 to 70 ° C. (varies depending on the season) is generated between the hot water and the outside air temperature around the pipeline including immediately after the remaining. .

路が長い程無駄が生じるというものであった。Although the heat-supply pipe line is provided with a heat-insulating pipe as a measure for preventing heat dissipation, heat energy dissipation from this portion cannot be ignored due to the large temperature difference from the outside air. If the interval between the hot water and the next hot water is long and the time is long, the heat energy will be dissipated as long as the free time is enough. All of the hot water will be wasted, and even if you try to obtain hot water at room temperature (outside temperature) or more at the time of the subsequent hot water collection, the hot water from the tank will not be discharged unless the above residue is discharged from the piping. The energy dissipation loss of the hot water is such that the higher the boiling temperature of the water heater and the longer the hot water supply piping, the more waste occurs.

To provide a hot water supply system capable of supplying hot water or water at a desired temperature to a place, and minimizing wasteful consumption of hot water supplied from a water heater and energy of the hot water as much as possible.
