DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the amount of hot water [6] that uses a heating device that controls the amount of heating based on a deviation signal between the set temperature of a temperature setting device and the hot water temperature detected by one temperature detector. be.

A conventional water heater is constructed as shown in FIG. That is, in FIG. 1, 1 indicates a heat source, and this heat source 1 is composed of a hot water storage tank 3 which is insulated with a heat insulating material 2, and a heat exchanger 4 installed inside the hot water storage tank 3. A heat medium feed pipe 6 is connected to the heat exchanger 4 from the collector 6 via a circulation pump 7, and a return pipe 8 is also connected to the heat exchanger 4. Reference numeral 9 indicates a controller, and signals from a high-temperature side sensor 10 provided in the collector 6 and a low-temperature side sensor 11 provided below the hot water storage tank 3 are input to the controller 9 to control the circulating bonozo 7. I'm doing j. From the negative part of the hot water storage tank 3, a hot water supply pipe 12 is connected.
It is distributed to the bathtub 16 via a water heater 13 and a water heater 14 which are heating devices. This'+reL
A flow control valve 16 is arranged at the tip of x4,
The flow rate control valve 16 is composed of a main body 17 and an integrated flow rate setting dial 18. When the user sets this integrated flow rate setting dial 18 to the second setting immediately after hot water is supplied, the main body 1
The valve inside the main body 17 is set to 1" in an open state. When hot water is supplied in this state, the water wheel inside the main body 17 rotates,
This rotation rotates the integrated flow rate setting dial 18 via the gear), and when the set amount of hot water is supplied, the FII
The structure is such that the valve inside the body 17 opens and the hot water supply is stopped. (Not shown) Next, to explain the internal configuration of the water heater 13, 19 indicates the combustion amount of the burner 20,
＃、、1 Detects the humidity at the outlet of the temperature setting device 21 and the heat exchanger 22.
It is controlled by the I''i controller 24.

26 indicates a city water faucet to the bathtub 15, and 26 indicates a pressure reducing valve 2.
7 is a water supply pipe provided, and is piped to the lower part of the hot water storage tank 3.

To explain the operation of the conventional example configured in this way, during the daytime, heat is stored in the hot water storage tank 3 by the collector 5 via the heat exchanger 4.
00e, and when heating hot water at 40°C with heat stored at 30°C due to rainy weather, set the ridge, temperature setting device 21, and integrated flow rate setting dial 18 to 4.
By setting 00G and 1701, the bathtub 15
Hot water heated to a caloric temperature by a water heater 13 is supplied to the water heater 13.
When the amount of hot water supplied reaches the set flow rate, the flow meter control valve 16 is activated and the hot water supply is stopped.

However, it was sunny on Moe 1 and 2001 was used after 6000 was stored in 3001 hot water storage tank 3, and the remaining 60°
There are times when the water temperature is 100β at C and the remaining water temperature is 2004 due to rainy weather.

In such a case, set the temperature setting device 21 and the integrated flow rate setting dial 18 to 40°C1 and 170e, respectively.
When the faucet 14 is opened, since the hot water tank 3 is at a high temperature of 114 degrees, the bathtub 15 is filled with 600C/111 water.
00/Hot water is supplied, then 4o 0CK with water heater 13
When the fJ〃a hot water is supplied 704, the flow rate control valve 16 is activated and the hot water is dispensed. However, in this case, compared to the set value, 20°C × 100
The amount of heat for 4 minutes is equivalent to 1 extra hot water supply, so when actually using the bathtub 15, it is necessary to open the phantom 5, the snake 1125, supply water, and turn the inside of the bathtub 15 after 400 e. Therefore, depending on the size of the bathtub, the bathtub may overflow when the faucet 26 is opened and water is supplied, and energy obtained from solar heat is used for the bathtub, which is contrary to energy conservation.

The present invention solves the conventional drawbacks such as: Even when the temperature of hot water supplied from the heat source side changes midway through,
The bathtub should only be supplied with hot water that is suitable for bathing.
