種方式の集合住宅用セントラル給湯装置が提案さ
れている。 Generally, in housing complexes such as apartments and condominiums, it is more advantageous in terms of installation space and exhaust gas treatment to install a hot water supply system in one place and adopt a centralized hot water supply system, rather than installing a water heater in each dwelling unit. For this reason, various types of central water heaters for apartment buildings have been proposed.

えなかつた。 However, as shown in FIG. 3, a conventional central water heater of this type is equipped with a water heater 1 equipped with a plurality of instantaneous water heaters in parallel and a large heat exchanger 2. The hot water is circulated through the heat exchanger 2 via the circulation pipe 3, and this hot water is heat exchanged with the water supplied into the heat exchanger 2.
Hot water for hot water supply is produced indoors. In addition, in such a central hot water supply system, a temperature detector is disposed in the circulation pipe 3, and a heat exchanger using hot water supplied from the heat exchanger 2 according to a temperature change of the circulating hot water in the circulation pipe 3 is installed. 2 is detected, and the number of operating instantaneous water heaters of the water heating device 1 is sequentially increased or decreased in accordance with this load fluctuation, thereby increasing or decreasing the amount of circulating hot water. Therefore, in conventional central water heaters of this type, heat loss is large because hot water is constantly circulated, and a large heat exchanger is required in addition to each instantaneous water heater, which increases equipment costs. I had no choice but to colander.

The purpose of this invention is to eliminate the need for large heat exchangers, suppress heat loss, reduce running costs, and reduce equipment costs.

0aを参照)。 In the water heater A configured in this manner, the hot water storage tank 20 is filled with hot water within the set temperature range, the water level of the hot water is at L1 , and each of the solenoid valves 12a to 12c, 35a is closed. Each instantaneous water heater 10a-10c is in a non-operating state. In this state, the hot water tap 41a of each dwelling unit H 1 and H 2
When at least one of ~41d and 42a~42d is opened, hot water in the hot water storage tank 20 flows into the hot water pump 33.
Hot water is supplied to each dwelling unit H 1 and H 2 by a, and the amount of hot water in the hot water storage tank 20 changes depending on the amount of hot water used.
Water level fluctuates. When the water level of hot water in the hot water storage tank 20 falls and reaches L2 , the level switch 21
detects this and opens the first solenoid valve 12a. As a result, water is supplied to the heat exchanger section 11 of the first instantaneous water heater 10a, and at the same time, the first instantaneous water heater 10a is activated, and hot water at a predetermined temperature flows from the first instantaneous water heater 10a into the hot water storage tank 20. will be replenished. When the amount of hot water supplied is greater than the amount of hot water used, the water level in the hot water storage tank 20 rises and reaches L1 . When the water level reaches L 1 , the level switch 21 detects this and the first
The solenoid valve 12a is closed to deactivate the first instantaneous water heater 10a, and further supply of hot water is stopped. That is, when the amount of hot water used is less than the amount of hot water supplied by the first instantaneous water heater 10a, the first instantaneous water heater 1
Only 0a repeatedly operates and deactivates (Fig. 2 1

図10a,10bを参照)。 When the amount of hot water used exceeds the amount of hot water supplied to the first instantaneous water heater 10a, the level of hot water in the hot water storage tank 20 further decreases and reaches L3 . When the water level reaches L3 , the level switch 21 detects this and opens the second solenoid valve 12b. As a result, water is also supplied to the heat exchanger section 11 of the second instantaneous water heater 10b, and the second instantaneous water heater 10b also operates, and hot water at a predetermined temperature is supplied from the first and second instantaneous water heaters 10a and 10b. The hot water storage tank 20 is replenished. Both instantaneous water heaters 10a,
When the amount of hot water supplied from 10b is greater than the amount of hot water used, the water level in the hot water storage tank 20 rises to L 2
reach. When the water level reaches L2 , the level switch 21 detects this and closes the second electromagnetic valve 12b to deactivate the second instantaneous water heater 10b. That is, the amount of hot water used is less than the hot water supply amount of both instantaneous water heaters 10a and 10b, and the first instantaneous water heater 10a
If the supply amount of hot water is larger than the amount of hot water supplied, only the second instantaneous water heater 10b repeatedly operates and deactivates while the first instantaneous water heater 10a remains in operation (the second

When the amount of hot water supplied is greater than that of hot water a and 10b, the third instantaneous water heater 10c also operates and the three instantaneous water heaters 10
Hot water is replenished from a to 10c, and only the third instantaneous water heater 10c repeatedly operates and deactivates between water levels L3 to L4 (Fig. 2 10a, 10b, 10c).

の温水は常時設定温度範囲内に保持される。 On the other hand, when all the instantaneous water heaters 10a to 10c continue to be inactive and the temperature of the hot water in the hot water storage tank 20 gradually decreases due to heat radiation and reaches the lower limit of the set temperature range, the thermostat 23 is turned off. This is detected and the solenoid valve 35a is opened. As a result, the hot water in the hot water storage tank 20 is circulated through the heat exchanger section 11 of the first instantaneous water heater 10a by the hot water supply pump 33a, and the first instantaneous water heater 10a is operated. Therefore, the hot water in the hot water storage tank 20 is circulated and heated by the first instantaneous water heater 10a, and when it reaches the upper limit of the set temperature range, the thermostat 23 detects this, closes the solenoid valve 35a, and closes the solenoid valve 35a. 1 instant water heater 10a
deactivate. Thereby, the hot water in the hot water storage tank 20 is always maintained within the set temperature range.

内に保持することができる。 In this way, in the hot water supply device A, the load fluctuation of the hot water supply device due to the use of hot water is handled by the hot water storage tank 20.
This is done based on the hot water level within the tank, that is, the amount of hot water used, so it is possible to eliminate the hot water circulation that was conventionally performed all the time to detect load fluctuations, and it is possible to significantly reduce heat loss. It is possible to omit the large heat exchanger that was used for each instantaneous water heater. Furthermore, according to the water heater A, even if the instantaneous water heaters 10a to 10c are inactive for a long time, the hot water in the hot water storage tank 20 is circulated for a short period of time to operate one instantaneous water heater. By only operating for a short time, the hot water in the hot water storage tank 20 can be maintained within the set temperature range at all times.
