  Moreover, in this invention, in order to give such a bathroom heating dryer A the function of a mist sauna, the mist sauna part 31 is incorporated. The mist nozzle 6 of the mist sauna section 31 is disposed in the grill plate 17, and the mist water supply line 7 is communicated with the mist nozzle 6. In this example, the mist nozzle 6 includes a large mist nozzle 6a and a small mist nozzle 6b. The large mist nozzle 6a sprays a relatively large mist of particles at a large flow rate, for example, about 1 liter / min. The small mist nozzle 6b sprays mist with relatively small particles at a small flow rate, and is, for example, about 0.5 liter / min. Mist opening / closing valves 28a, 28b such as electromagnetic valves are provided in front of the mist nozzles 6a, 6b, and mist is selectively generated from the large mist nozzle 6a and the small mist nozzle 6b by opening / closing the mist opening / closing valves 28a, 28b. It comes to be sprayed. In the case of this example, the mist sauna unit 31 is mounted on the bathroom heater / dryer main body 16. In FIG. 2, reference numeral 34 denotes a box containing mist opening / closing valves 28a and 28b.
The mist water supply pipe 7 is supplied with tap water such as tap water, and is provided with a strainer 29 and a water supply opening / closing valve 8 such as an electromagnetic valve in order from the inlet side. The heating hot water pipe 2 is provided with a mist heating pipe 4 in parallel with the hot air heat exchanger 3, and the mist heating pipe 4 is provided in the middle of the mist heating pipe 4. A proportional valve 30 is provided to control the flow of hot water flowing in the water. A mist heat exchanger 12, which is a liquid heat exchanger such as a plate heat exchanger, is disposed between the mist heating pipeline 4 and the mist feed water pipeline 7. The water for mist flowing through the mist feed pipe 7 is heated by the hot water flowing through the mist. A mist drain pipe 9 is branched from the mist feed pipe 7 between the mist heat exchanger 12 and the mist open / close valves 28a, 28b, and water in the mist feed pipe 7 is drained from the mist drain pipe 7. It can be discharged from the road 9 into the bathroom 5 and out of the bathroom 5. The mist drain line 9 is provided with a drain opening / closing valve 10 such as an electromagnetic valve, and a vacuum breaker 33 that prevents negative drainage from flowing back due to negative pressure. Further, a mist hot water thermistor TH1 for detecting the temperature of hot water flowing through the mist water supply pipe 7 is disposed between the mist heat exchanger 12 and the mist open / close valves 28a and 28b.
  When the mist sauna bath is used, the water supply opening / closing valve 8 is opened to supply water to the mist supply pipe 7 and the proportional valve 30 is opened to circulate hot water through the mist heating pipe 4. Thereby, the water flowing through the mist feed pipe 7 is heated by the mist heat exchanger 12, and the hot water flows through the mist feed pipe 7. When the mist open / close valves 28a and 28b are opened in this state, hot water mist is selectively sprayed from the large mist nozzle 6a and the small mist nozzle 6b to perform a mist sauna bath. When the mist is sprayed from the large mist nozzle 6a, a large amount of heat is obtained and a hard mist sauna bath can be obtained, and when the mist is sprayed from the small mist nozzle 6b, a fine mist is sprayed to form a soft mist sauna bath. When the mist sauna bath is performed in this manner, the bathroom heater / dryer A is heated as described above to raise the temperature in the bathroom 5 so that the mist sauna bath can be comfortably performed.
The bathroom heating / drying machine A of the present invention has the above-described structure, but after the bathroom heating / drying machine A is installed in the bathroom 5, a trial operation is performed in accordance with a command from the heat source machine 1 side. . In the case of the present invention, in addition to the trial operation of the bathroom heater / dryer main body 16 side automatically, the mist sauna unit 31 is also automatically trial run, and the trial run is performed according to the flow shown in FIG. A portion indicated by * in FIG. 4 is a portion added for automatic test operation of the mist sauna unit 31. This flow will be described as follows.
When the trial operation switch of the heat source device 1 is turned on, a heating trial operation start signal is output, the heating lamp “strong” blinks, and the heating trial operation is started. At this time, the heating on / off valve 22, the water supply on / off valve 8, the drain on / off valve 10, and the proportional valve 30 are opened, and water is supplied to the heating hot water pipe 3 and filled with water, and the water supply pipe 7 is filled with water. When the mist water supply pipe 7 is filled with water, since the drain opening / closing valve 10 is opened, the air in the mist water supply pipe 7 is removed and the mist water supply pipe 7 is quickly filled with water. That is, the water can be filled much more quickly than when the mist opening / closing valves 28a and 28b are opened and filled. When a predetermined time (for example, 3 minutes) elapses from the start of water filling, the drain opening / closing valve 10 is closed because the air in the mist water supply pipe 7 has escaped and the water has been filled. The water filling end signal is issued and level change of the heat source unit 1 side may turn without.
  When the water filling end signal is detected, the circulation fan 21a is turned on, the mist opening / closing valves 28a and 28b are opened, and the temperature of the bathroom 5 is measured by the bathroom temperature thermistor TH3. Then, it is determined whether the temperature of the bathroom 5 has risen by, for example, 3K before a predetermined time (for example, 9 minutes 30 seconds) elapses. At this time, the temperature of hot water flowing through the heating hot water pipe 2 is measured by the heating hot water thermistor TH2, and the temperature of mist hot water in the mist water supply pipe 7 is measured by the mist hot water thermistor TH1, and the predetermined time (for example, Within 9 minutes and 30 seconds), it is determined whether the temperature of the hot water in the hot water pipe 2 for heating has become, for example, 40 ° C or higher, or whether the temperature of the hot water for mist in the mist water supply pipe 7 has become, for example, 40 ° C or higher. . The temperature of the bathroom 5 does not rise 3K within a predetermined time, the temperature of the hot water in the heating hot water pipe 2 does not exceed 40 ° C., or the temperature of the hot water for mist in the water supply pipe 7 for mist is 40 ° C. If not, the trial run determination is NG, an abnormality is displayed, the automatic trial run becomes abnormal, and the operation is stopped. On the other hand, the temperature of the bathroom 5 rises by 3K within a predetermined time, the temperature of the hot water in the heating hot water conduit 2 becomes 40 ° C. or higher, and the temperature of the mist hot water in the mist water supply conduit 7 becomes 40 ° C. or higher. At that time, the test run determination is OK, the test run result is transmitted to the heat source unit 1, the heating on-off valve 22, the water supply on-off valve 8, the mist on-off valves 28a and 28b, the proportional valve 30 are closed, and the circulation fan 21a is When it is turned off and a test run end signal is issued, the heating lamp “strong” is turned off and the test run ends.
  In the above example, the mist open / close valves 28a and 28b made of electromagnetic valves are provided as close as possible to the mist nozzles 6a and 6b, so that water and air can be removed by the intrusion of air from the mist nozzles 6a and 6b when the mist sauna is not used. In the example shown in FIG. 5, the mist opening / closing valves 28 a and 28 b are separated from the mist nozzles 6 a and 6 b and are provided at positions close to the mist heat exchanger 12. As a result, valves such as the mist opening / closing valves 28a and 28b, the proportional valve 30, the water supply opening / closing valve 8, and the drainage opening / closing valve 10 are concentrated on the mist heat exchanger 12, so that assembly of wiring and the like is performed. It becomes easy to do. In the case of this example, in this state, air replacement in the pipe between the mist opening / closing valves 28a, 28b and the mist nozzles 6a, 6b due to air intrusion from the mist nozzles 6a, 6b and water contamination occur, but this is prevented. Therefore, check valves 32a and 32b are provided in the vicinity of the mist nozzles 6a and 6b. The check valves 32a and 32b are normally closed, and are opened only when a predetermined or higher water pressure is applied from the water supply pipe 7 for mist. When the check valves 32a and 32b are provided in this way, the mist sauna is closed when the mist sauna is not used, and air does not flow in. As a result, the distance between the mist nozzles 6a, 6b and the mist opening / closing valves 28a, 28b can be increased, wiring and assembly can be facilitated, and hygienic effects (contaminated water is not sprayed) can be obtained. In the case of the bathroom heating / drying machine A having such a structure, the bathroom heating / drying machine A may be water-filled as follows when the bathroom heating / drying machine A is installed and trial run is performed. That is, when water is filled in the mist water supply pipe 7, water is injected while the water supply on / off valve 8 and the drain on / off valve 10 are opened and the air is removed. At this time, if the mist on / off valves 28a and 28b are also opened, Water filling can be smoothly performed before the valves 32a and 32b.
