ある。(Problems to be Solved by the Invention) However, the only known methods have been proposed to solve the disadvantages of a pair of forced air on/off type combustors. First of all, I have never seen a combustor where one is an on/off type and the other is a combustor that burns in proportion to the hot water temperature, especially when one of the first and second combustors is on/off. This is a controlled type combustor, in which the other combustor changes the combustion amount in proportion to the hot water temperature from a small capacity, which is smaller than the combustion amount of the first combustor, to a large capacity, which is larger than the combustion amount of the first combustor. When a combustor is used in which the air flow rate can be changed in accordance with the amount of combustion, there is a disadvantage that combustion becomes unstable due to the influence of the other combustor, especially when the capacity of the proportionally controlled combustor is small.

It has a built-in second combustor, and the exhaust from both combustors is performed through a common exhaust stack, and the first combustor is configured as an on/off type combustor, and the second combustor A combustor whose combustion amount changes in proportion to the temperature of the load from a small capacity with a combustion amount smaller than the combustion amount of the first combustor to a large capacity which is larger than the combustion amount of the first combustor, and the air volume of the fan changes in accordance with the combustion amount. In the configuration, the fan rotation speed when the second combustor burns at a small capacity while the first combustor fan is operating is:
The air volume of the fan of the second combustor is increased by the amount suppressed by the blowing pressure of the fan of the first combustor.

hrThe combustion amount of the second combustor is from 7000kcal/hr
If it is possible to adjust up to 30000kcal/hr,
The first combustor achieves proper combustion with an air volume of about 30 m 3 /hr, while the second combustor achieves proper combustion with an air volume of about 20 m 3 /hr.

い。 The control circuit B of the second combustor 2 includes an auxiliary switch 15 that opens and closes in conjunction with the additional heating switch 5, a hot water supply switch 16 that closes when a hot water supply or drop button parallel to this is pressed, and a second Coil 17a of the electromagnetic proportional valve 17 interposed in the gas supply path of the combustor 2
, a motor 2d-1 of the fan 2d, and a resistor 1
8, 19, a thermistor 20 that detects the hot water temperature as a load, and a variable resistor 2 that sets the hot water temperature.
1, resistors 18, 19 and thermistor 20
A bridge is constructed with a variable resistor 21 and a variable resistor 21 to detect the difference between the bath temperature and the set temperature in the form of a potential difference between connection points C and D, and the potential difference, that is, the voltage is amplified by arithmetic amplifiers 22 and 23. Applying the output signal to the base of the transistor 24 intervening in the coil 17a of the electromagnetic proportional valve 17, applying a current to the coil 17a according to the voltage applied to the base,
The output signal is further amplified by an amplifier 26 and an amplifier 27 with a variable resistor 25 that can set the degree of amplification, and the output signal is applied to the motor 2d of the fan 2d.
In addition to the base of the transistor 28 inserted at the base of the transistor 2d-1, a current corresponding to the voltage applied to the base can be applied to the motor 2d-1. In the control circuit B, 16a is a switch that opens and closes in conjunction with the hot water supply switch 16 interposed in the coil 17a of the electromagnetic proportional valve 17, 29 is a variable resistor for setting the voltage of the operational amplifier 26, In the slow ignition circuit 30, when combustion in the second combustor 2 is detected in the flame rod 31, the transistor 32 becomes conductive and the output signal from the operational amplifier 33 is switched to low. , the transistor 2
It loses the output signal added to the base of 4.
This is not particularly different from what is conventionally known.

The transistor 13 intervened in the motor 1d-1 of
In addition to the base, the fan 1d was always operated while the second combustor 2 was in operation.
次に本装置の作動を説明する。 Next, the operation of this device will be explained.

するのを防ぐ。 When closing the switch 16 to fill the hot water now,
After slow ignition with the output from the slow ignition circuit 30, a voltage is applied to the coil 17a according to the output signal from the operational amplifiers 22 and 23 depending on the temperature of the hot water.
A current flows in accordance with this, opens and closes the proportional valve 17 in accordance with the current value, and the motor 2d-1 of the fan 2d also rotates at a corresponding rotation speed, and the second combustor 3 enters the operating state. Furthermore, the motor 1d-1 of the fan 1d also starts rotating in response to the output signal from the control circuit B, thereby preventing the exhaust gas from the second combustor 2 from flowing into the first combustor 1 side.
しかしこの第１燃焼器１のフアン１ｄの回転数
即ちこれに比例する風量は第６図に示すごとく常
に一定の例えば30m3／hrである。 However, the rotational speed of the fan 1d of the first combustor 1, that is, the air volume proportional to this rotational speed is always constant, for example, 30 m 3 /hr, as shown in FIG.

m 3 /hr to 60m 3 /hr, especially when the second combustor 2 is burning at a low capacity, it would normally be affected by the wind pressure from the first combustion fan 1d, as shown in Figure 4. As shown by the solid line, even though the engine is rotating at a predetermined number of revolutions, this may not be achieved, resulting in poor combustion.

路Ｂからの出力により回転し続ける。 In this case, by adjusting the degree of amplification, that is, the slope of the variable resistor 25 that can set the degree of amplification provided in the amplification device 26, as shown by the dotted line in FIG. The rotation speed of the second combustor 2 is changed by the blowing pressure of the fan 1d of the first combustor 1.
This inconvenience can be solved by increasing the air volume of the fan 2d by the amount that can be suppressed.Especially in the case where the hot water obtained from the second combustor 2 is used for hot water supply for showering or other purposes, the hot water output due to changes in combustion can be eliminated. It is possible to obtain hot water at a desired temperature without changing the temperature, thereby improving the feeling of use. Furthermore, when closing the reheating switches 5 and 15 for reheating, the control circuit A is activated, and the first combustor 1 is controlled to be turned on and off by the control circuit A as shown in FIG.
During this time, the fan 2d of the second combustor 2 also continues to rotate due to the output from the second control circuit B.

では、実質的にあまり影響がない。 Incidentally, when the second combustor 2 burns at high capacity,
The air volume of the fan 2d of the second combustor 2 is the same as that of the first combustor 1.
According to this, the air volume increases from that of fan 1d.
It is thought that the air volume of the fan 2d influences that of the first combustor 1, but compared to a combustor that is proportionally controlled, a combustor that is ON/OFF controlled has a wider stable combustion range, and is less affected. Even if there is a change in the combustion and the temperature of the outlet water changes as a result of this, in the case where the first combustor 1 is used for reheating as shown in the figure, there is substantially no effect.

して成る。 In addition, in FIG. 1, the outlet 2e of the heat exchanger 2b of the second combustor 2 is connected to a pipe 35 that connects to the bathtub 34.
The pipe line 35 has a check valve 37, a three-way valve 38, a pump 39, and a water flow switch 40 interposed therein. When the bath push button provided on the remote control is pressed, the solenoid valve 41 provided at the outlet 2e opens, the three-way valve 38 switches, and the pop 39 operates to close the pipe. The structure is such that hot water is filled through a channel 35, and when a certain amount of hot water is filled, a water pressure sensor 42 provided in the bathtub 34 is activated.
operates to stop the pump 39, close the electromagnetic valve 41, and switch the three-way valve 38. When the electromagnetic valve 41 is closed and the water flow switch 43 provided in the second combustor 2 is turned off, the second combustor 2 is also deactivated and the hot water filling operation is completed.
