The ventilation fan 127 is operated by driving the ventilation fan motor so that the room air can be ventilated by sucking indoor air from the ventilation intake port 122 and exhausting it from the exhaust port 124 to the outside.

  The bathroom heating / ventilating apparatus 101 with a mist function is controlled by a built-in controller 145. The controller 145 is connected to the remote controller 146 through a signal line 151, and is connected to the heating heat source machine 112 through a signal line 152. In this embodiment, the controller 145 is built in the main unit 111. The remote controller 146 remotely operates the bathroom heating / ventilation apparatus 101 with a mist function, and includes a heating / ventilation operation switch 148, a mist operation switch 149, and a power switch 150. The controller 145 has a built-in timer (clock) for measuring the elapsed time from the end of the sterilization process.

  FIG. 4 is a functional block diagram showing an electrical configuration around the controller 145 in the bathroom heating / ventilating apparatus 101 with a mist function. The controller 145 performs microcomputer control of the bathroom heating / ventilation apparatus 101 with a mist function in accordance with a program for operation processing stored in a memory such as ROM or EEPROM. That is, as shown in FIG. 4, the controller 145 receives signals from the heating / ventilation operation switch 148, the mist operation switch 149, the temperature sensor 139, and the power switch 150, and in accordance with the signals, the heating heat source unit 112, the heating water Ventilation and heating (drying) in the bathroom by controlling the supply valve 140, the diversion valve 141, the mist water amount adjustment valve 142, the mist injection valve 143, the sterilization heater 138, the hot air blower 126, and the ventilation blower 127 The mist injection and the mist water supply pipe 135 are sterilized.

  FIG. 5 is a flowchart showing the mist operation of the bathroom heating / ventilating apparatus 101 with a mist function by the controller 145. Hereinafter, the operation from the operation start to the operation end of the mist operation of the bathroom heating / ventilation apparatus 101 with a mist function will be described with reference to FIG. While the operation of the bathroom heating ventilator 101 with mist function is stopped, the heating heat source unit 112, the hot air blower 126, and the ventilation blower 127 are stopped, and the heating water supply valve 140, the diversion valve 141, and the mist water amount adjustment are stopped. Both the valve 142 and the mist injection valve 143 are closed. In addition, it is assumed that no current flows through the sterilization heater 138 and the heater is not heated.

  When the power switch 150 of the remote controller 146 is pressed to turn on the power, the bathroom heating / ventilating apparatus 101 with a mist function starts operation according to the flowchart of FIG. First, when the power switch 150 is turned on, the controller 145 confirms the elapsed time from the previous sterilization process (step S1), and if the predetermined time T1 or more has elapsed (in the case of Yes in step S2), the sterilization The heater 138 is turned on and heating of the water staying in the mist water supply pipe 135 is started (step S3). At this time, the temperature sensor 139 monitors the temperature of the water staying in the mist water supply pipe 135. When the temperature of the water staying in the mist water supply pipe 135 reaches a predetermined temperature and settles (step S4), the temperature is maintained for a predetermined time to perform sterilization. The sterilization treatment with the sterilization heater 138 is preferably performed at a rate of about 70 ° C. to 80 ° C. for several minutes at a rate of about once a day. When the predetermined time T2 elapses (step S5), the sterilization heater 138 is turned off (step S6), and the process returns to step S1 again to enter a standby state. In this standby state, a predetermined time T1 from the previous sterilization process and whether the mist operation switch 149 is turned on are monitored (step S7). If the mist operation switch 149 is not turned on within the predetermined time T1, the operations shown in steps S3 to S6 are performed again to perform the sterilization process.

  On the other hand, when the mist operation switch 149 is pressed and turned on and a mist operation start command is sent from the remote controller 146 to the controller 145, the heating heat source unit 112 starts operating (step S8) and the water diversion valve 141 is opened. (Step S9), water circulates between the heating heat source unit 112 and the mist water heat exchange 136. When the mist water heat exchanger 136 reaches a temperature sufficient for heating the water in the mist water supply pipe 135, the mist water amount adjustment valve 142 and the injection valve 143 are opened (steps S10 and S11). Accordingly, water flows into the mist water supply pipe 135 from the clean water, and mist-shaped hot water is injected from the mist water injection nozzle 134 into the bathroom.

  When the mist operation switch 149 is pressed again to turn off and a mist operation stop command is sent from the remote controller 146 to the controller 145 (step S12), the mist water amount adjustment valve 142 and the injection valve 143 are closed (steps S13 and S14). The heating heat source machine 112 is also stopped (step S15), the water diverter valve 141 is also closed (step S16), and the mist operation is ended (step S17). When the mist operation ends, the process returns to step S1 and enters a standby state.

  Next, the operation from the start to the end of the heating / ventilation operation of the bathroom heating / ventilating apparatus 101 with a mist function will be described with reference to FIG. FIG. 6 is a flowchart showing the heating / ventilating operation of the bathroom heating / ventilating apparatus 101 with a mist function by the controller 145.

  First, when the heating / ventilation operation switch 148 of the remote controller 146 is pressed and turned on, the bathroom heating / ventilation apparatus 101 with a mist function starts the heating / ventilation operation according to the flowchart of FIG. 6. First, when the heating / ventilation operation switch 148 is turned on, the heating heat source unit 112 starts operating (step S21), and the hot air fan 126 and the ventilation fan 127 also start operating (steps S22 and S23). Further, the heating water supply valve 140 is opened (step S24), and hot water is supplied from the hot water outlet pipe 131 to the heating heat exchanger 125. Therefore, the air in the bathroom sucked into the circulation chamber 114 from the circulation intake port 121 is heated by the heating heat exchanger 125 and then blown out into the room as warm air from the discharge port 123. Further, the air in the bathroom sucked from the ventilation inlet 122 is exhausted from the exhaust outlet 124 to the outside. When the heating / ventilation operation switch 148 is pressed again to be turned off and a heating / ventilation operation stop command is sent from the remote controller 146 to the controller 145 (step S25), the heating heat source unit 112 stops operating (step S26), and the heating water is supplied. The supply valve 140 is closed (step S27). Further, the operation of the hot air blower 126 and the ventilation blower 127 is also stopped (steps S28 and S29), and the heating and ventilation operation is ended (step S30).

  As described above, the water staying between the mist water injection nozzle 134 and the mist water heat exchanger 136 can be heated by the sterilization heater 138 to kill Legionella and other germs. Therefore, it is not necessary to separately provide a pipe for draining the water being used, and the piping can be simplified.

  In the heating / ventilation operation, indoor heating and drying and ventilation may be individually performed. That is, in the heating and ventilation operation, if the ventilation fan is not operated, only indoor heating can be performed. Conversely, if only the ventilation fan is operated, only indoor ventilation can be performed. Further, the mist operation and the heating / ventilation / drying operation may be performed simultaneously. If it does so, moisture can be replenished, heating the inside of a bathroom, and indoor drying can be prevented.

  In the bathroom heating and ventilating apparatus 101 with a mist function, the mist injection direction and the size of water droplets can be changed by replacing the mist water injection nozzle 134 with a different shape. Further, if the mist water injection nozzle 134 is moved by a motor or the like, the mist can be uniformly injected into the bathroom.
