The ion generator 44 is an example of an ion generating means, and an ion emission surface is exposed to a circulation air passage 43a formed by setting the damper 40 to a circulation position or a circulation ventilation position.

The ion generator 44 generates both positive ions and negative ions or negative ions. The principle of generation of positive ions and negative ions is that a corona discharge is caused by boosting and applying an AC voltage taken from a household AC power source or the like between a pair of electrodes opposed so as to interpose a dielectric, Oxygen or water in the air is ionized by receiving energy by ionization, and H ⁺ (H ₂ O) _m (m is an arbitrary natural number) and O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number). The main ions are emitted.

These H ⁺ (H ₂ O) _m and O ₂ ⁻ (H ₂ O) _n adhere to the surface of the floating bacteria and chemically react to generate H ₂ O ₂ or .OH as an active species. Since H ₂ O ₂ or .OH exhibits very strong activity, they can surround and remove airborne bacteria. Here, .OH is one kind of active species, and represents radical OH.

  Accordingly, in association with the operation of the fan unit 32, approximately the same number of positive ions and negative ions are generated, and air containing approximately the same number of positive ions and negative ions is blown, thereby allowing floating bacteria contained in the circulating air to It is possible to remove both floating bacteria in the air of the bathroom 101 shown in FIG.

When the impeller 35 is driven to rotate, the air A in the bathroom 101 is sucked from the suction port 38 of the fan unit 32 through the suction grill 45 of the front panel 26.

  When the position of the damper 40 is the circulation position shown in FIG. 6A, the circulation air passage 43a from the suction port 38 to the blowout port 41 is formed in the fan part 32, so that the air A sucked from the suction port 38 Is blown out into the bathroom 101 through the circulation air passage 43a from the outlet 41 through the outlet grill 46 of the front panel 26.

  Since the heater part 33 is arrange | positioned at the blower outlet 41 of the circulation air path 43a, when the heater part 33 is driven, the air which passes along the circulation air path 43a is warmed, and the warm air HA blows off from the blowing grill 46a.

  Thus, when the fan motor 36 is rotationally driven with the damper 40 as a circulation position, when the heater unit 33 is driven, the hot air HA is blown out into the bathroom 101 while circulating the air in the bathroom 101. .

<Operation example of mist mode of this embodiment>
FIG. 12 is a flowchart showing an example of the embodiment of the mist mode executed in the bathroom air-conditioning system 1A of the present embodiment. Next, each drawing shows the flow of processing when the mist mode is executed of the present embodiment. The description will be given with reference.

  Step SA1: A bather or the like presses the mist operation selection button 71 of the mist operation unit 5 installed in the bathroom 101 or humidifies and heats the bathroom 101 or the main operation unit 6 installed in the washroom 102. The heating operation selection button 81 is pressed a predetermined number of times to select the mist mode.

  Step SA2: When the mist operation selection button 71 of the mist operation unit 5 is pressed, the mist control unit 71 of the mist generating device 2 determines that the mist mode is selected, and the mist operation lamp 75 of the mist operation unit 5 blinks. In addition, a mist operation command is transmitted to the main control unit 8 of the bathroom air conditioner 3.

  Here, in the state where the mist operation lamp 75 is blinking in the mist operation unit 5, the operation in the mist mode is started, but in order to increase the temperature of the bathroom 101, the mist operation lamp 75 is in a standby state without ejecting mist. This is notified to a bather or the like in the bathroom 101.

  Step SA3: When receiving the mist operation command from the mist control unit 7, the main control unit 8 determines that the mist mode is selected, and blinks the mist operation lamp 81a of the main operation unit 6.

  Here, in the state where the mist operation lamp 81a is blinking in the main operation unit 6, the operation in the mist mode is started, but the mist operation lamp 81a is in a standby state without ejecting mist in order to raise the temperature of the bathroom 101. This is notified to the user before bathing outside the bathroom 101.

  When the mist mode is selected by pressing the heating operation selection button 81 of the main operation unit 6, the main control unit 8 determines that the mist mode is selected and transmits a mist operation command to the mist control unit 7. . When receiving the mist operation command from the main control unit 8, the mist control unit 7 determines that the mist mode has been selected and causes the mist operation lamp 75 to blink, and returns the mist operation command to the main control unit 8. And the main control part 8 will blink the mist operation lamp 81a, if the reply of the mist operation command from the mist control part 7 is received.

  Step SA4: When starting the operation in the mist mode, the main control unit 8 of the bathroom air conditioner 3 controls the bathroom air conditioner 3 to perform the heating operation. That is, the main control unit 8 controls the fan motor 36 so that the fan air volume becomes “strong”, for example, and energizes the heater unit 33. Further, the damper motor 40b is controlled to bring the damper 40 into the circulating position shown in FIG.

  Thereby, the bathroom air conditioner 3 blows the hot air HA into the bathroom 101 from the blowing grill 46 of the front panel 26 while circulating the air in the bathroom 101. In the bathroom air conditioner 3, since an electric heater such as a PTC heater is used as the heater unit 33, the time from the start of energization until the heater unit 33 is heated to a predetermined temperature is short, and the hot air HA The rise time until blowing out is short. Further, since the fan air volume is set to “strong”, the amount of hot air HA blown out increases.

  Therefore, in the mist mode, the temperature in the bathroom 101 can be raised to a temperature suitable for mist ejection in a short time.

  In addition, in order to notify that the bathroom air conditioner 3 is performing the heating operation, the main control unit 8 transmits a predetermined command to the main operation unit 6 and the mist control unit 7, and the strong heating operation lamp of the main operation unit 6 is transmitted. 81b is turned on, and the strong heating operation lamp 76a of the mist operation unit 5 is turned on.

  Step SA5: The main controller 8 of the bathroom air conditioner 3 detects the temperature TH1 in the bathroom 101 by the temperature detection sensor 31 in order to detect that the inside of the bathroom 101 is in a predetermined state when the operation in the mist mode is started. To do. In this processing step, it is determined whether or not the temperature TH1 in the bathroom 101 has reached a predetermined mist ejection start temperature (for example, 30 ° C.) suitable for mist ejection.

  Step SA6: When the main controller 8 of the bathroom air conditioner 3 determines that the temperature TH1 in the bathroom 101 has become equal to or higher than the mist ejection start temperature (for example, 30 ° C.) in Step SA5 described above, the mist controller of the mist generator 2 The operation permission command is transmitted to 7. When receiving the operation permission command from the main control unit 8, the mist control unit 7 controls the mist generating device 2 to perform the drain operation.

  FIG. 13 is a flowchart showing an example of the drainage operation, and the flow of the drainage operation performed before mist ejection will be described.

  Step SB1: The mist control unit 7 of the mist generator 2 opens the hot water supply switching electromagnetic valve 19a of the valve unit 2B.

  Step SB2: The mist control unit 7 of the mist generator 2 opens the drainage switching electromagnetic valve 19c of the valve unit 2B. Thereby, the hot water HW supplied from the hot water supply device 4 is drained from the drain pipe 15c. At this time, the supply switching electromagnetic valve 19b is closed, and mist is not ejected from the nozzle unit 2A.

  Step SB3: When the mist control unit 7 of the mist generating device 2 starts the drain operation, the water temperature detection sensor 20 detects the water temperature TH2 of the hot water HW supplied from the hot water supply device 4.

  In this example, it is detected whether the water temperature TH2 of the hot water HW supplied from the hot water supply device 4 has reached a predetermined mist ejection suitable temperature (for example, 30 ° C.) suitable for mist ejection, and the water temperature TH2 is suitable for mist ejection. When the temperature reaches 30 ° C. (for example, 30 ° C.), it is determined that the water temperature is suitable for mist ejection, and the processes after step SA7 in the flowchart shown in FIG. 12 are performed.

  Here, in the mist mode, heating of the bathroom 101 is started by the bathroom air conditioner 3, and after the temperature TH1 in the bathroom 101 reaches a predetermined temperature, the drain operation is started by the mist generating device 2, whereby the amount of discharged water Can be reduced.

  Step SA7: When the mist control unit 7 of the mist generating device 2 determines that the water temperature TH2 of the hot water HW supplied from the hot water supply device 4 in the drainage operation described above has become equal to or higher than a predetermined mist ejection compatible temperature (for example, 30 ° C.) The mist operation lamp 75 of the mist operation unit 5 is switched from blinking to lighting, and a buzzer is sounded.

  Here, in the state where the mist operation lamp 75 is lit in the mist operation unit 5, the mist operation is notified to a bather or the like in the bathroom 101 that the mist is ejected in the mist mode. The lamp 75 serves as first state notification means.

  In addition, not only the notification by the lamp but before the mist is blown, the buzzer is sounded to prompt the user to leave the room when the user is in the bathroom 101 while wearing clothes.

  Step SA8: The mist control unit 7 of the mist generating device 2 ejects mist, so that the hot water switching electromagnetic valve 19a of the valve unit 2B is opened, the drain switching electromagnetic valve 19c is closed, and the supply switching electromagnetic valve 19b is opened. open. Thereby, the hot water HW of the predetermined temperature supplied from the hot water supply device 4 is supplied to the nozzle unit 2A, and the mist M is ejected by the nozzle unit 2A.

  Step SA9: The main control unit 8 of the bathroom air conditioner 3 detects that the interior of the bathroom 101 is in a predetermined state after transmitting an operation permission command to the mist control unit 7 of the mist generating device 2 in Step SA6 described above. Therefore, the temperature TH1 in the bathroom 101 is detected by the temperature detection sensor 31. In this processing step, the temperature TH1 in the bathroom 101 is higher than the mist ejection start temperature (for example, 30 ° C.), which is the predetermined room temperature described above, which is a condition for starting mist ejection, and is a predetermined bathing suitable temperature (for bathing) ( For example, it is determined whether or not the temperature has reached 35 ° C.

  Step SA10: When the main control unit 8 of the bathroom air conditioner 3 determines that the temperature TH1 in the bathroom 101 is equal to or higher than the bathing suitability temperature (for example, 35 ° C.) in Step SA9 described above, the mist operation lamp of the main operation unit 6 81a is switched from blinking to lighting.

  Here, in the state where the mist operation lamp 81a is lit in the main operation unit 6, the inside of the bathroom 101 is in a predetermined middle temperature and high humidity mist sauna state, and it is outside the bathroom 101 that it is suitable for bathing. The user before bathing is informed, and the mist operation lamp 81a is the second state informing means.

  In step SA5 shown in FIG. 12, the temperature in the bathroom 101 is detected by the temperature detection sensor 31 and the state in the bathroom 101 is determined. However, the time is measured by a timer, and the bathroom 101 is measured when a predetermined time elapses. It may be determined whether or not the state becomes a state suitable for mist ejection.

  Moreover, you may make it judge the state in the bathroom 101 combining the detection of the room temperature by the temperature detection sensor 31, and the measurement of the elapsed time by a timer.

  Furthermore, it may be determined whether or not the inside of the bathroom 101 is in a state suitable for mist ejection by other means such as a humidity sensor.

  Also in step SA9 shown in FIG. 12, the time may be measured by a timer, and it may be determined that the interior of the bathroom 101 is a mist sauna environment suitable for bathing when a predetermined time elapses. The combination of the detection of the room temperature by 31 and the measurement of the elapsed time by the timer, or other means such as a humidity sensor may be used to determine that the state is suitable for bathing.

  As described above, in the bathroom air-conditioning system 1A of the present embodiment, after the operation in the mist mode is started, the bathroom 101 is in a mist sauna state and suitable for bathing. Since the main operation unit 6 installed in 102 notifies the user before bathing or the like, it is possible to grasp that the inside of the bathroom 101 is in a comfortable state while outside the bathroom.

  Accordingly, it is possible to prevent the bather from entering the room before the inside of the bathroom 101 is sufficiently warmed and feeling cold.

  When the mist operation unit 5 installed in the bathroom 101 is operated to start the operation in the mist mode, the bathroom 101 is first heated by the bathroom air conditioner 3 to raise the temperature in the bathroom 101, and then the mist. Since the mist is ejected by the generator 2, the mist is not ejected before the inside of the bathroom 101 is sufficiently warmed, and it is possible to prevent the cold from being felt.
