弁１２を給湯開始位置へ開ける。In the hot water supply system II shown in FIG. 8, a flow rate detection means 3 and a human water temperature detection means 4 are attached to the water supply pipe 2 to detect the amount of water supply II and the temperature of incoming water. 5 is a heat exchanger HA alr, and a hot water temperature detection means 6 is attached to the outlet side to detect the outlet hot water temperature.
7 is a gas pipe, and a proportional valve 8 is installed in the middle to linearly vary the gas amount. 9 is a burner. 10 is a mixing valve to which the outlet side pipe of the heat exchanger 5 and the water supply pipe 2 are connected. The mixing valve 10 has a mixing valve 12 attached to the outlet pipe 1l of the heat exchanger 5 and the water supply pipe 2, and is energized by a driving means 13. The pipes merge downstream of the mixing valve 12 to form a mixing pipe 14, and a mixing water temperature detection means 15 and a mixing flow rate detection stage 16 are installed midway. Mixing pipe l
There is a switching valve 17 at the terminal further downstream of the switch 18.
Or switch the flow path to shower 19. 20 is a control unit which receives operation signals from the operation stage 21 and controls the water heater l. Next, we will explain the operation of Yokoi in the conventional example. When it is desired to drain water from the shower head 1B or the shower 19, the operating means 21 operates the set temperature of the heat exchanger 5 outlet, the set temperature of the kissing valve 10, the hot water supply slip setting, and each switch for starting hot water supply, and sends the information to the control unit 20. The control unit 20 energizes the drive stage 13 to open the mixing valve 12 to the hot water supply starting position.

湯される。When the proportional valve 8 is opened, the flow rate detection means 3 detects the water condition, so the control section 20 opens the proportional valve 8 and starts combustion in the burner 9. The hot water heated by the heat exchanger 5 is sent to the mixing valve IO via the outlet pipe 1l. Also, the control unit 20 controls the amount of gas from the proportional valve 8 so that the outlet hot water temperature reaches the set temperature! Section II1 and adjust the combustion amount. The mixing valve 10 adjusts the mixing ratio so that water from the water supply pipe 2 and hot water from the outlet pipe 1l are mixed and the water temperature reaches a set temperature. That is, the mixed water temperature is detected at the mixed water detection stage 15,
The mixing ratio is adjusted through 13 drive stages to correct the deviation from the set temperature! Section III. The r1 mixed hot water further passes through a mixing pipe l4 and is discharged from a shower l8 or a shower l9.

。Problems to be Solved by the Invention However, in such a water heater, when the set temperature at the outlet of the heat exchanger 5 is high and the temperature of the water supplied from the water supply pipe 2 increases, the mixing valve 10 adjusts the mixing ratio in a direction that reduces the amount of hot water. (The fire extinguishing flow rate is the limit flow rate when stopping combustion to prevent boiling.)

い。Is the amount of hot water supplied to the mixing valve 10 extinguishing? When the temperature drops below the beak and combustion stops, the set temperature at the outlet of the heat exchanger 5 is adjusted downward. However, the settings have been changed and water is supplied to the pumping valve lO until combustion starts again, so when using a shower lO, etc., you are suddenly exposed to low-temperature water and feel uncomfortable. In addition, until the combustion starts again and the hot water reaches the new set temperature, the hot water level fluctuates greatly, and the user feels that the hot water temperature gets hotter or colder, making it inconvenient to use.

Find the temperature deviation from the detected temperature at the aRs5 outlet and the set temperature. 28 is a flow rate determination means that determines whether the supply agitation is greater than or equal to the extinguishing fluid. 29 is P! The incineration calculation means detects that the amount of water supplied from the flow rate determination means 28 to the heat exchanger 5 is greater than the extinguishing flow rate {When No. 3 is input, the optimum combustion rate is determined from the obtained temperature deviation signal. An energizing output is provided to a heating source 31 such as a proportional valve 8 or a heat source drive stage 30 (for example, a fan or an igniter). Numeral 32 is a hot water temperature setting adjustment means that determines the initial thermal energy from the supply line, the supply freezing point, and the set temperature, and when a signal that has decreased to near the extinguishing flow rate is input from the flow rate determining means 28, the set temperature is adjusted to the maximum XI!

める。As the temperature of the supplied water gradually increases as summer approaches, the mixing ratio to the amount of water in the hot water mound decreases and becomes close to the extinguishing flow rate. First, in this case, calculate the total thermal energy from the supplied IR amount and the difference between the set temperature and the human water temperature. Next, from the relationship between the flow rate and the set temperature that give the same amount of energy, a set temperature is selected that is within the range above the extinguishing flow rate and that achieves the set value of the hot water made in the mixing stage 22. The obtained set temperature is input to the deviation calculating means 27 and the water temperature is set from 1,000 steps 26 {1^
The deviation is determined by giving priority to the above, and the combustion amount is determined based on this deviation.

向上している。The hot water heated by the above-mentioned operation is mixed with water by the mixing means 22, and the hot water is adjusted to a set temperature and supplied from the shower 18 or the shower 19. The supply water temperature changes depending on the season, but as it gradually rises, the mixing ratio of the amount of hot water to the amount of water decreases. Therefore, when the supplied hot water reaches near the extinguishing flow rate, the total energy of the supplied hot water is first calculated from the difference between the set temperature and the incoming water temperature and the supplied flow rate. Then, based on the relationship between the supplied amount of energy and the set temperature, an optimal set temperature is selected that is equal to or higher than the extinguishing flow rate and achieves the hot water temperature setting {1α in the mixing means 22. After that, supply the water to the new set temperature. By doing this, even if the supplied water temperature fluctuates, you can freely change the set temperature of the heating 'tA3l without causing the fire to go out, so that you can always continue to use hot water at a more stable temperature of your preference than in the shower 19. Effects of the Invention As described above, when the inventive water inlet fan is detected by the hot water temperature detection means and the water supply flow rate reaches near the extinguishing flow rate, the total energy is calculated from the set temperature, human water temperature, and water supply flow rate. By adjusting the temperature setting to the optimum temperature using the hot water setting adjustment means based on the relationship between the set temperature and the water supply flow rate, a vortex can be constantly supplied without extinguishing the water, and hot water at a stable temperature can always be used, eliminating discomfort caused by fluctuations in hot water temperature. User-friendliness has been improved without the need for
