The hot water is further heated by an auxiliary heating device 3 and then sent to a hot water supply pipe 4. Therefore, if the hot water user does not need high-temperature hot water, the hot water sent from the auxiliary heating device 3 and the water from the water supply pipe 1 are mixed at the hot water supply port at the end of the hot water supply pipe 4. I had to use it. Therefore, in conventional hot water systems, unless high-temperature hot water is used, the high-temperature hot water is heated by the auxiliary heating device 3 and then cooled with water from the water supply pipe 1. This has disadvantages in that a large amount of energy is wasted in the device 3, and it takes time and effort to adjust the desired temperature of the hot water.

する。<Purpose of the Invention> The present invention has been made in view of the above circumstances, and by appropriately mixing hot water or water from the heat storage tank with hot water using a three-way switching valve and a mixing valve, the hot water supply temperature can be adjusted. It is an object of the present invention to provide a hot water supply system that can freely adjust energy consumption and prevent wasted energy in an auxiliary heating device. The hot water from the heated heat storage tank is supplied to the hot water supply piping via the mixing valve, and the hot water from the heat storage tank is switched between the high temperature hot water from the auxiliary heating device and the water from the water supply pipe by a three-way switching valve and sent to the mixing valve. and a three-way switching valve control means for switching the three-way switching valve by comparing the set temperature and the heat storage temperature, and adjusting the mixing flow rate of the mixing valve by comparing the hot water supply temperature and the set temperature. A mixing valve control means is provided.

給湯温度センサによって検出される。The set temperature is the temperature of hot water desired by the user when supplying hot water and set by operating the hot water supply temperature setting means. The heat storage temperature is the temperature of hot water in the heat storage tank, and is detected by the heat storage temperature sensor. Hot water temperature is the temperature of hot water in the hot water piping,

れるように制御を行う。Specifically, the three-way switching valve control means switches the three-way switching valve to the auxiliary heating device side when the set temperature is higher than the heat storage temperature, so that hot water from the auxiliary heating device is sent to the mixing valve, and controls the setting. When the temperature is lower than the heat storage temperature, the three-way switching valve is switched to the water supply pipe side and water from the water supply pipe is controlled to be sent to the mixing valve.

高温の湯の流星を増加させるように混合弁を制御する。The mixing valve control means controls the hot water supply temperature so that it approaches the set temperature, but the operation is reversed depending on the switching state of the three-way switching valve. Specifically, when the three-way switching valve is switched to the auxiliary heating device side and the hot water supply temperature is higher than the set temperature, the flow rate of hot water from the heat storage tank is increased,
When the hot water supply temperature is lower than the set temperature, the mixing valve is controlled to increase the flow of hot water from the three-way switching valve.

加させるように混合弁を制御する。When the three-way switching valve is switched to the water supply pipe side, contrary to the above, when the hot water temperature is higher than the set temperature, the flow rate of water from the three-way switching valve is increased, and the hot water/temperature is increased. When the temperature is lower than the set temperature, the mixing valve is controlled to increase the flow rate of hot water from the heat storage tank.

御によって設定温度に近づくように調整される。When the hot water supply system of the present invention is configured as described above, when the set temperature is higher than the heat storage temperature, the hot water from the heat storage tank is mixed with hot water from the auxiliary heating device for hot water supply, and the hot water supply temperature is set at a mixed temperature. The temperature is adjusted to approach the set temperature by controlling the mixing flow rate using a valve. In addition, if the set temperature is lower than the heat storage temperature, hot water from the heat storage tank is mixed with water from the water supply pipe to supply hot water, and the hot water temperature is adjusted to approach the set temperature by controlling the mixing flow rate with the mixing valve. be done.

管路１３が設けられている。Unlike hot water storage type water heaters, instantaneous water heaters have the disadvantage that if the flow rate of hot water decreases below a certain level, combustion will stop and they will no longer be able to supply high-temperature hot water. Therefore, when this instantaneous water heater is used as the auxiliary heating device 3 in the first embodiment, when the set temperature is slightly higher than the heat storage temperature, the mixing valve 8 allows the auxiliary heating device 3 to Since the flow rate of the hot water is suppressed and combustion in the instantaneous water heater is stopped, it has sometimes become impossible to raise the hot water temperature to the set temperature.

Therefore, if the flow rate of the bypass pipe 13 is adjusted using the throttle valve 14 so that it is equal to or higher than the minimum supply flow rate of the instantaneous water heater, which is the auxiliary heating device 3, hot water can be constantly supplied. This makes it possible to eliminate the inconvenience of the hot water supply temperature being lower than the desired set temperature.

The three-way switching valve is set by comparing the set temperature set by the user's operation with the hot water temperature setting means and the heat storage temperature, which is the temperature of the hot water in the heat storage tank. , a three-way switching valve control means that switches to the auxiliary heating device side when the set temperature is higher, and switches to the water supply pipe side when the set temperature is lower; Mixing valve control means for appropriately mixing hot water from the heat storage tank with high temperature hot water or water from the three-way switching valve using a mixing valve based on comparison with the temperature, and adjusting the mixing flow rate so that the hot water supply temperature approaches the set temperature. A hot water supply system characterized by the following: （２）前記三方切換弁からの高温の湯または水の一部を
混合弁を介さずに給湯配管に送り込むことができるバイ
パス管路を設けた特許請求の範囲第１項記載の給湯シス
テム。(2) The hot water supply system according to claim 1, further comprising a bypass pipe line through which hot water or a portion of the water from the three-way switching valve can be sent to the hot water supply piping without going through the mixing valve.
