<Operation example in dry operation mode>
Next, an operation example of the drying operation mode in the bathroom air conditioner 1 will be described. 9-11 is explanatory drawing which shows the ventilation direction at the time of dry operation mode, and has shown the state by which the bathroom air conditioner 1 was installed in the bathroom 24 demonstrated in FIG. 9 to 11 show a state in which the laundry 41 as the object to be dried is hung on the land pipe 28 in the bathroom 24.

  The bathroom air conditioner 1 has a configuration in which the rotation speed of the fan motor 8 can be switched to the second speed so that the fan unit 3 can obtain two levels of airflow of “strong” and “weak”. Normally, the fan motor 8 is controlled by the control unit 30 so as to obtain a “strong” constant air volume. The fan motor 8 is controlled by the control unit 30 so as to obtain a “weak” air volume smaller than “strong” in another bathing / heating operation mode to be described later.

  The control unit 30 described with reference to FIG. 7 executes the drying operation mode when the drying mode button 38 of the operation unit 31 is pressed. In the dry operation mode, as shown in FIG. 4, the control unit 30 controls the damper motor 32 so that the position of the damper 11 becomes a circulation ventilation position in which ventilation is performed while circulating the air in the bathroom 24. Further, in the drying operation mode, the control unit 30 turns on the heater 5. In the drying operation mode, the fan motor 8 is controlled by the control unit 30 so that, for example, the above-described “strong” air volume is obtained.

  When the fan 7 is rotationally driven by the fan motor 8, the air in the bathroom 24 is sucked from the suction port 10 of the fan unit 3 through the suction port 6 b of the front panel 6. When the position of the damper 11 is the circulation ventilation position, both the circulation air passage 14 from the suction port 10 to the blowout port 12 and the ventilation air passage 15 from the suction port 10 to the exhaust port 13 are formed in the fan unit 3. . For this reason, a part of the air sucked from the suction port 10 passes through the ventilation air passage 15 and the exhaust port 13 and is further exhausted from the exhaust grill 27 to the outside through the exhaust duct 26 shown in FIG.

  In addition, by exhausting the air in the bathroom 24 to the outside, air in the bathroom 23 and the like is sucked from an air intake port 29 a provided in the bathroom door 29.

  A part of the air sucked from the suction port 10 passes through the circulation air passage 14 and is blown out from the blower outlet 12 into the bathroom 24 through the blower outlet 6 a of the front panel 6. Then, when the heater 5 is turned on and the heater 5 is heated, the air passing through the circulation air passage 14 is warmed and hot air blows out from the outlet 12.

  Further, as shown in FIGS. 5A to 5C, the control unit 30 controls the angle of the blades 21 of the louver 17 to change continuously or intermittently, which is indicated by an arrow A in FIG. The blowing direction of the air blown into the bathroom 24 within the range changes continuously or intermittently in a swing (swing) shape. FIG. 10 shows a state in which air is blown from the air outlet 12 toward the laundry 41, and FIG. 11 shows a state in which air is blown from the air outlet 12 in a direction other than the laundry 41. It is.

  When air is blown in the direction of the laundry 41 indicated by the arrow B in FIG. 10, the speed of change in the air blowing direction is slower than when air is blown in the direction other than the direction of the laundry 41 indicated by the arrow C in FIG. 11. That is, in other words, the louver 17 is controlled by the control unit 30 so that the changing speed of the angle of the blade 21 of the louver 17 becomes slow.

  When the blowing direction of the air blown into the bathroom 24 continuously changes in a swing (swinging) shape, when blowing in the direction of the laundry 41 indicated by the arrow B in FIG. The louver 17 is controlled by the control unit 30 so that the rate of change in the angle of the blades 21 of the louver 17 becomes slower than when blowing air in directions other than the direction of the laundry 41 indicated by the arrow C.

  Moreover, when the blowing direction of the air blown into the bathroom 24 changes in a swing (swinging) shape step by step, when blowing in the direction of the laundry 41 indicated by the arrow B in FIG. The louver 17 is controlled by the control unit 30 so that the stop time of the blades 21 of the louver 17 at each stage is longer than when blowing air in directions other than the direction of the laundry 41 indicated by the arrow C of 11.

  When the louver 17 is controlled by the control unit 30 as described above, when air is blown in the direction of the laundry 41 indicated by the arrow B in FIG. 10, the direction other than the direction of the laundry 41 indicated by the arrow C in FIG. Compared with the time of ventilation, the speed of the change in the blowing direction becomes slower.

  The angle at which the louver 17 moves in a swing (swing) shape, as indicated by arrows A, B, and C in FIGS. 9 to 10, is set as follows, for example. A user or a contractor uses the louver setting button 25 of the operation unit 31 to set the position of the land pipe 28 in the bathroom 24 in the bathroom air conditioner 1 as a reference position. Based on the angle with respect to the set reference position, the louver 17 operates in a swing (swing) shape for a predetermined angle set in advance.

  Further, the angle at which the louver 17 moves in a swing (swing) shape indicated by arrows A, B and C in FIGS. 9 to 10 is directly applied to the bathroom air conditioner 1 by the louver setting button 25 of the operation unit 31. The louver 17 may be set to swing (swing) based on the set angles.

  As described above, the louver 17 is controlled by the control unit 30 and the blowing direction of the air blown into the bathroom 24 changes in a swing (swing) shape, so that it is heated by the heater 5 in the dry operation mode. Air is applied to a wide area of the laundry 41. Thereby, the laundry 41 whole can be dried efficiently.

  Further, the air heated by the heater 5 is blown to a wide range in the bathroom 24, and the air in the bathroom 24 is circulated. Thereby, the wall surface in the bathroom 24 can be dried and the drying of the location where the warm air of the laundry 41 does not directly hit can be promoted, and the entire laundry 41 can be further efficiently dried.

  Further, the air heated by the heater 5 is blown for a longer time in the direction of the laundry 41 shown in FIG. 10 than in the direction other than the laundry 41 shown in FIG. 11. Thereby, the laundry 41 can be dried more efficiently.

  Furthermore, a part of the air in the bathroom 24 is exhausted to the outside, and the air in the bathroom 24 is ventilated by taking in the air from the air intake port 29a. Drying of the product can be promoted.

<Operation example of heating operation mode>
Next, an operation example of the heating operation mode in the bathroom air conditioner 1 will be described. The heating operation mode in the bathroom air conditioner 1 includes a preheating operation mode and a bathing heating operation mode. The preliminary heating operation mode is an example of a pre-bath heating operation mode, and the bath heating operation mode is an example of a heating operation mode during bathing.

  First, an operation example in the preliminary heating operation mode will be described. FIG. 12 is an explanatory diagram showing an example of air blowing in the preheating operation mode, and shows a state where the bathroom air conditioner 1 is installed in the bathroom 24 described in FIG.

  The control unit 30 described with reference to FIG. 7 executes the preheating operation mode when the preheating mode button 34 of the operation unit 31 is pressed. In the preheating operation mode, as shown in FIG. 1, the control unit 30 controls the damper motor 32 so that the position of the damper 11 becomes a circulation position for circulating the air in the bathroom 24. Further, in the preliminary heating operation mode, the control unit 30 turns on the heater 5. In the preliminary heating operation mode, the fan motor 8 is controlled by the control unit 30 so that, for example, the above-described “strong” air volume is obtained.

  When the fan 7 is rotationally driven by the fan motor 8, the air in the bathroom 24 is sucked from the suction port 10 of the fan unit 3 through the suction port 6 b of the front panel 6. When the position of the damper 11 is the circulation position, a circulation air passage 14 from the suction port 10 to the outlet 12 is formed in the fan unit 3. For this reason, the air sucked from the suction port 10 passes through the circulation air passage 14 and is blown out from the blower outlet 12 into the bathroom 24 through the blower outlet 6 a of the front panel 6. Then, when the heater 5 is turned on and the heater 5 is heated, the air passing through the circulation air passage 14 is warmed and hot air blows out from the outlet 12.

  In the preheating operation mode, the angle of the blades 21 of the louver 17 is controlled by the control unit 30 as shown in FIG. Therefore, in the preheating operation mode, as shown in FIG. 12, the air heated by the heater 5 is blown out toward the floor of the washing place 24 b in the bathroom 24.

  Thereby, in the preheating operation mode, the inside of the bathroom 24 can be heated while circulating the air in the bathroom 24, and the temperature of the washing place 24b can be raised.

  Next, an operation example in the bathing heating operation mode will be described. FIG. 13 is an explanatory view showing an example of air blowing in the bathing heating operation mode, and shows a state where the bathroom air conditioner 1 is installed in the bathroom 24 described in FIG.

  The control part 30 demonstrated in FIG. 7 will perform bathing heating operation mode, if the bathing heating mode button 35 of the operation part 31 is pushed. In the bathing heating operation mode, as shown in FIG. 1, the control unit 30 controls the damper motor 32 so that the position of the damper 11 is a circulation position for circulating the air in the bathroom 24. Further, in the bathing / heating operation mode, the control unit 30 turns on the heater 5. In the bath heating operation mode, for example, the fan motor 8 is controlled by the control unit 30 so as to obtain the above-described “strong” air volume.
