At the bottom of tank a, a natural circulation heat exchanger is installed in a tilted manner to allow natural circulation, and water is supplied from the bottom of hot water tank a.
Hot water was tapped from the top of the hot water tank d. In this configuration, 1. Since the heat exchange method is a natural circulation method, even if the temperature in the hot water storage tank drops if a large flow rate continues for a long time, an instantaneous temperature rise cannot be expected. Cold water may come out after using a large amount of hot water, such as when boiling hot water.2 A natural circulation heat exchanger is installed at the bottom of the hot water tank, so when Burner C is not burning, There is a large loss due to heat radiation. 3. Because the capacity of the hot water storage tank cannot be reduced in order to cope with the hot water supply load, a lot of heat is radiated from the surface of the hot water storage tank and the installation space is large. It had such problems.
発明の目的

給湯機のみで出湯するという作用を有する。With this configuration, when the hot water temperature of the instantaneous hot water heater rises to SP, the high temperature hot water of the hot water storage type water heater is supplied through the connected circuit, and when the hot water temperature of the instantaneous hot water heater rises to 7, the circuit is switched to the bypass circuit. This has the effect of bypassing the hot water storage type water heater and dispensing hot water only with the instantaneous water heater.

状態とな−・でいる。Here, the operation of the control valve 14 is determined by the outlet water temperature Ta of the instantaneous hot water heater.
If Ta is T3 or more, the bypass circuit and the instantaneous hot water heater are connected to each other to bypass the hot water storage water heater. A circuit A is constructed in which the instantaneous hot water heater and the hot water storage type hot water heater 8 are connected in series by communicating with each other. Hot water temperature (outlet temperature) of type water heater T
a, T1 and T2 are lower, so the three-way valve is in the circuit state.

れる。<t1 to t2>, Ta starts to rise when hot water supply starts from 1 to 1, but since there is no water at T2, the three-way valve continues to be in the circuit state. Therefore, the temperature of the hot water heated by the hot water supply device is the hot water temperature Tb of the hot water storage type water heater, and the hot water is discharged at T4. <t
2>, the three-way valve switches to circuit B because Ta reaches T3. Therefore, the hot water storage type water heater is bypassed, and the hot water output temperature of the water heater becomes Ta, and hot water starts to be directly tapped from the instantaneous water heater.0<t2~t3>i, j:, Since Ta is greater than or equal to T3. Continue circuit B. <t3-t4>
T
At o<t4> when a starts to decrease, the three-way valve switches to circuit A because Ta becomes t2. From then on, this state continues intermittently until hot water supply starts.The hot water storage tank used here compensates for the delay in the rise of hot water temperature in instant water heaters, and the rise time of instantaneous water heaters is generally short. , the capacity of the hot water tank can be made very small. Therefore, the heat radiation loss from the surface of the hot water storage tank is small and energy is saved.In addition to the effects of the present invention, the water heater of the present invention provides the following effects.
１、給湯開始時に瞬間式給湯機と貯湯式給湯器どを直列

Since the hot water storage type water heater is bypassed when the hot water temperature of the instantaneous type hot water heater rises, the hot water storage capacity of the hot water storage type water heater can be made smaller. ), the heat radiation loss from the surface of the hot water tank will be reduced. Also, the installation space can be reduced.
