When the sensor does not detect the second water level, it is configured to perform a hot water operation to the water storage tank. In addition, the above-mentioned “selectively branched” refers to a state in which one or both of them can be selected as an actual distribution route in a state where the heating pipe is branched and connected to the mist circuit and the heating circuit. Say.

In such a configuration, the mist can be generated at a low pressure without using a pressurizing pump by dropping hot water onto the mist plate to cause splashing. Also, the hot water that falls is collected in the water storage tank,

Next, the internal structure of the hot water supply / heating unit 4 will be described for reference. FIG. 2 is a diagram showing the internal structure of the hot water supply / room heater 4. In the figure, a heat exchanger 402 for heating and a heat exchanger 403 for hot water supply are provided in a gas combustion chamber 401.
, And a heating burner 404 and a hot water supply burner 405 are provided correspondingly. The heating water outgoing pipe 408 on the heating side is connected to the heating pipe 2 of FIG.
Numerals 9 are respectively connected to the return pipes 3 in FIG. The combustion of the heating burner 404 and the hot water supply burner 405 is controlled by a burner controller 420. In order to perform the heating operation, first, when the operation switch is turned on in a state where water is higher than the level (L level) of the water level sensor 406 in the make-up water tank 416, the circulation pump 407 is operated, and the heating heat exchanger 402 is operated.

When the fire is completed, the flame rod 414 detects this and the combustion lamp 419 is turned on to stop the spark. Thereafter, the thermistor 415 detects the temperature of the hot water according to the heating load, and the temperature of the heating water is automatically changed. When the load is reduced, the heating valve 413 is opened and closed to perform on / off control of combustion. The operation of the circulation pump 407 is continued even when the combustion is off. When the heating operation switch is turned off, the safety valve 412 and the heating valve 413 are closed, the flame of the heating burner 404 is extinguished, the combustion lamp 419 is extinguished, and the fan 410 and the circulation pump 407 are stopped. When the water in the make-up water tank 416 becomes lower than the detection level (L level) of the water level sensor 406, the make-up water solenoid valve 417 connected to the discharge side of the make-up water valve 421 opens, and the level of the water level sensor 418 ( H level). Other members on the hot water supply side include a water governor 422 and a water amount sensor 42.

It should be noted that since a heating-only machine can be used instead of the above hot water supply / heating machine 4, the internal structure of the heating-only machine will be described for reference. FIG. 3 is a diagram showing the internal structure of the heating-only machine 4A. In the figure,
In the gas combustion chamber 401, a heat exchanger 402 and a burner 4 are provided.
04 is provided. The heating water outgoing pipe 408 is connected to the heating pipe 2 in FIG. 1, and the heating water return pipe 409 is connected to the return pipe 3 in FIG. The combustion of the burner 404 is controlled by a burner controller 420. To perform the heating operation, first, the water level sensor 406 is provided to the makeup water tank 416.
When the operation switch is turned on in a state where there is water at or above the level, the circulating pump 407 is operated, and the mist heater 1 from the heating water outgoing pipe 408 through the heat exchanger 402 (FIG. 1)
And a circulation circuit returning to the heating water return pipe 409 is formed. Next, the fan 410 is driven, and the ignition plug 411 is turned on.
At the same time as starting spark, the original gas solenoid valve 431 and the heating gas solenoid valve 432 are opened, gas is supplied through the gas governor 433 and the burner 404 is ignited. When the fire is completed, the flame rod 434 detects this and the combustion lamp 419 is turned on to stop the spark. Thereafter, the thermistor 415 detects the temperature of the hot water according to the heating load, and the temperature of the heating water is automatically changed. When the load is reduced, the original gas solenoid valve 431 and the heating gas solenoid valve 432
Are opened and closed to perform on / off control of combustion. The operation of the circulation pump 407 is continued even when the combustion is off. When the heating operation switch is turned off, the original gas solenoid valve 43
1 and the heating gas solenoid valve 432 are closed and the burner 404 is closed.
Is extinguished, the combustion lamp 419 turns off, and the fan 41
0 and the circulation pump 407 are stopped. If the water in the makeup water tank 416 becomes lower than the detection level of the water level sensor 406, combustion is not performed unless water is manually injected until the water level becomes higher than the detection level again.

Next, the operation of the bathroom mist heating system configured as described above will be described. First, the heating operation will be described. In FIG. 1, when performing the heating operation, the operation switch provided on the main remote controller 6 or the dedicated remote controller 10 is pressed, and then the heating operation switch of the dedicated remote controller 10 is turned on. As a result, the hot water supply / room heater 4 (or the heating apparatus 4A, the same applies hereinafter) performs the heating operation. At this time, the three-way valve 102 is at the first valve position, and the solenoid valve 113 is closed. Therefore, the heating pipe 2
The hot water for heating supplied to the bathroom mist heater 1 through the heating branch pipe 112 is radiated by the heat exchanger 106, passes through the return pipe 3, and returns to the hot water supply heater 4 in a circulation circuit (heating circuit). Form. When the circulation circuit is formed in this manner, since the return hot water temperature is higher than the tap water temperature, the amount of heat for reheating can be reduced, and the thermal efficiency is good.

Further, since the solenoid valve 113 is closed, so-called air leakage (inhalation of air) from the empty water storage tank 105 does not occur. Generally, a pump for a heating circuit (circulation pump 407 in FIGS. 2 and 3)
However, since there is no power to suck out the sucked air by itself and circulate hot water, there is a problem that the pump runs idle when air is generated, but such a problem is caused by closing the solenoid valve 113. Can be avoided.

On the other hand, the motor 10 in the bathroom mist heater 1
When the fan 8 is driven and the fan 107 is operated, the hot air that has taken heat from the surface of the heat exchanger 106 generates gallery 101.
c is sent out into the bathroom, so that the bathroom is heated.
Further, since the relative humidity is lowered by heating, the bathroom is dried. The air temperature in the bathroom is detected by the thermistor 114, and when the temperature reaches the set temperature, the heating operation is stopped. When the heating operation switch is turned off in the dedicated remote controller 10, the heating operation is stopped.

Next, the mist operation will be described. When performing the mist operation, after pressing the operation switch provided on the main remote controller 6 or the dedicated remote controller 10, the mist operation switch provided on the dedicated remote controller 10 or the bath remote controller 8 is pressed. At this time, the three-way valve 102 is at the second valve position, and the heating pipe 2 is in communication with the mist branch pipe 111. H level water level sensor 109 for water storage tank 105
Outputs an ON signal when the water level in the water storage tank 105 is lower than a predetermined water level. In an initial state where there is no water in the water storage tank 105, the H level water level sensor 10
9 outputs an ON signal. The hot water supply / heating unit 4 uses the H
Receiving the ON signal of the level water level sensor 109, the hot water operation is started. As a result, the same operation as the hot water operation for the bathtub is performed. However, it is not the bathtub but the water storage tank 105 that performs hot water.

When the water level of the water storage tank 105 reaches the set water level by the hot water operation, the H level water level sensor 10
9 outputs an OFF signal, and in response to this, the hot water supply / room heater 4 stops the hot water operation.

When the hot water supply operation to the water storage tank 105 is completed, the hot water supply / room heater 4 and the bathroom mist heater 1 start the mist operation. At this time, the motor 108 in the bathroom mist heater 1 is driven, and the fan 107 blows air. When the solenoid valve 113 is opened, the water storage tank 10 is opened.
5 communicates with the return pipe 3. When the mist operation is started, hot water flows from the heating pipe 2 to the mist branch pipe 111 via the three-way valve 102. The hot water flowing through the mist branch pipe 111 is poured from the shower head 103 to the mist plate 104, falls into the lower mist plate 104 one after another, and is finally collected in the water storage tank 105. In this manner, the hot water that is poured down onto the plurality of mist plates 104 and splashes and falls is filled with mist and steam, and is blown from the back side to the mist and steam. Is released from the gallery 101c into the bathroom. Thus, the bathroom is in the state of a mist sauna. The dropped hot water is collected in the water storage tank 105, forms a circulation circuit (mist circuit) that returns to the hot water supply / room heater 4 through the return pipe 3 via the solenoid valve 113 from the drain port 105a. When the circulation circuit is formed in this manner, since the return hot water temperature is higher than the tap water temperature, the amount of heat for reheating can be reduced, and the thermal efficiency is good.

During the mist operation, water is lost as mist or steam. Therefore, not all hot water supplied from the shower head 103 in the mist circuit is collected in the water storage tank 105, and the amount of hot water returned from the return pipe 3 is slightly smaller than the amount of hot water supplied from the heating pipe 2. Less. As a result, the water level in the water storage tank 105 gradually decreases as the mist operation time elapses. Then, when the water level falls to a predetermined L level water level, the detection signal of the L level water level sensor 110 is turned off, and the hot water supply / heater 4 receiving this stops the mist operation and starts the hot water operation to the water storage tank 105 again. Then, the water level of the water storage tank 105 is restored to a predetermined level. When the water level rises and the H level water level sensor 109 outputs an ON signal, the mist operation is started again.

When the mist operation switch is turned off in the dedicated remote controller 10 or the bath remote controller 8, a mist operation stop command is issued to the hot water supply / room heater 4. As a result, the mist operation stops.

Next, the combined operation of mist and heating will be described. For example, during the above-mentioned mist operation (water storage tank 10
The hot water to 5 has been completed. 3), when the heating operation switch is pressed, the three-way valve 102 is switched to the third valve position, and the heating pipe 2 communicates with not only the mist branch pipe 111 but also the heating branch pipe 112. As a result, hot water is supplied to the heating branch pipe 112 and the same operation as the above-described heating operation is performed, so that the mist can be put on warm air and discharged to the bathroom. In addition, when the mist operation switch is pressed during the heating operation, the heating operation is temporarily stopped, the hot water operation to the water storage tank 105 is performed, and then the mist operation and the heating operation are started.

In the above embodiment, the three-way valve 102 is used for switching between the mist circuit and the heating circuit. However, the same operation can be performed even if electromagnetic valves are provided in the mist branch pipe 111 and the heating branch pipe 112 instead. Can be performed.
