  The circulation fan unit 12 includes a multi-blade impeller 14 whose rotation axis is in the vertical direction, a circulation fan motor 15 that rotationally drives the impeller 14, and a circulation fan case 16 that forms an air passage.

  In the circulation fan case 16, a lower surface along the axial direction of the impeller 14 is opened to form a circulation fan suction port 17. Further, the circulation fan case 16 is formed with a blowout air passage 18 along a tangential direction of the impeller 14, and a lower surface communicating with the blowout air passage 18 is opened to form a circulation fan blowout port 19.

  In the circulation fan unit 12, when the impeller 14 is rotationally driven by the circulation fan motor 15, air is sucked from the circulation fan suction port 17, and the air sucked from the circulation fan suction port 17 passes through the blowing air passage 18. Then, the air is blown out from the circulation fan outlet 19.

  The air conditioning unit 11 includes a heater 20 h in the circulation fan unit 12. For example, a PTC heater is used as the heater 20h, and the heater 20h is attached to the blowout air passage 18 in the vicinity of the circulation fan outlet 19.

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.

  Thus, when the impeller 14 is driven to rotate and the ion generator 20 i generates approximately the same number of positive ions and negative ions, air containing approximately the same number of positive ions and negative ions blows out from the circulation fan outlet 19.

  The air sucked from the circulation fan inlet 17 flows to the circulation fan outlet 19 through the blowout air passage 18. When the heater 20 h is energized, the air passing through the blowout air passage 18 is heated, and hot air blows out into the bathroom 51 from the blowout grill 32 b of the front panel 32. Thereby, warm air is applied to the laundry hung on the land pipe 55.

  When the impeller 21 of the ventilation fan unit 13 rotates, the ventilation fan of the ventilation fan unit 13 passes from the suction grille 32a of the front panel 32 through the ventilation suction channel 30b formed by the ventilation channel forming member 30. Air in the bathroom 51 is sucked into the suction port 24.

  The air sucked from the ventilation fan suction port 24 flows to the exhaust port 26 through the exhaust air passage 25. Then, the air is exhausted to the outside through the outdoor grill 4 from the exhaust duct 3 connected to the exhaust duct joint 28a.

  Thus, by executing the drying operation mode, the hot air is applied to the laundry hung on the land pipe 55 while the steam and moisture in the bathroom 51 are discharged, and the laundry can be dried in a short time. it can.

  Here, the drying operation mode includes a standard mode and a silent mode. When the silent mode is selected, the impellers of the circulation fan unit 12 and the ventilation fan unit 13 are set so that the circulation air volume and the ventilation air volume are smaller than those in the standard mode. The number of revolutions is controlled.

  In the drying operation mode, the sterilization mode by supplying ions may be linked. Alternatively, the electric louver 33 may be swung within a predetermined range so as to blow out warm air over a wide range.

  When the circulation fan motor 15 is driven, the air in the bathroom 51 is sucked into the circulation fan suction port 17 from the suction port grill 32 a of the front panel 32 by rotating the impeller 14 of the circulation fan unit 12.

  The air sucked from the circulation fan inlet 17 flows to the circulation fan outlet 19 through the blowout air passage 18. In the cool air operation mode, since the heater 20h is not energized, wind (cool air) corresponding to the temperature in the bathroom 51 blows out from the outlet grill 32b of the front panel 32.

  In addition, when the ventilation fan motor 22 is driven, the impeller 21 of the ventilation fan unit 13 rotates, so that the air in the bathroom 51 is sucked into the ventilation fan suction port 24 from the suction grille 32a of the front panel 32. .

  The air sucked from the ventilation fan suction port 24 flows to the exhaust port 26 through the exhaust air passage 25. Then, the air is exhausted to the outside through the outdoor grill 4 from the exhaust duct 3 connected to the exhaust duct joint 28a.

  Thus, by executing the cool air operation mode, the cool air is blown into the bathroom 51 while ventilating the air in the bathroom 51, and the air conditioner 1A can be used as a fan in the summer.

(5) Setting mode When the setting button 43a is pressed on the operation unit 41A, the control unit 71 determines that the setting mode is selected.

  In the setting mode, setting of operation setting information such as ventilation air volume, presence / absence of operation of the electric louver 33, time for delaying stoppage of the ventilation operation called toilet delay, and the like is performed.

  Here, in the operation setting information, setting items (factors) whose setting values can be changed according to the operation mode are different. In this example, control is performed according to the operation mode being executed when the setting button 43a is pressed. The unit 71 determines a setting item whose setting value can be changed.

  In the setting mode, an alphabet indicating a setting item whose setting value can be changed is displayed at the hour position H of the display unit 46 for displaying the time, and a setting code, a setting item and a setting code are setting values of the setting item at the minute position M. The colon C that separates the characters blinks at a predetermined timing, for example, 1 Hz (1/2 Duty), and becomes the setting mode of the operation setting information in the selected operation mode.

  Table 1 below shows setting items whose setting values can be changed in each operation mode, and Table 2 shows setting codes and parameters.

  As shown in Tables 1 and 2, for example, in the dry operation mode, the presence / absence of interlocking of the sterilization mode of the setting item J and the switching of the wind direction by the electric louver 33 of the setting item P can be set.

  In the setting item J, whether or not ions are generated can be selected as shown in Table 2. In the setting item P, for example, as shown in Table 2, when the electric louver 33 is fixed, swinged, or fixed, an arbitrary fixed position is selected from a plurality of fixed positions according to the operation mode and the position selected by the user. Can be set. Note that the swing range may be set when the electric louver 33 is swung. Further, it is possible to perform an initial setting in which the blowing direction is the direction of the land re-pipe 55 in accordance with the direction in which the air conditioning unit 11 is installed.

  In the cool breeze operation mode and the heating operation mode, switching of the wind direction by the electric louver 33 of the setting item P can be set.

  In the ventilation operation mode, whether or not ions are generated by the sterilization mode of the setting item J, the air volume of the 24-hour ventilation of the setting item A, the delay time when the toilet ventilation is stopped of the setting item d, and the 24-hour ventilation of the setting item F The operation mode can be set.

  In the setting item A, for example, the air volume can be set according to the floor area of the house from a plurality of air volumes shown in Table 2. In the setting item d, for example, from among a plurality of times shown in Table 2, it is possible to select a time for delaying the stop by continuing ventilation when leaving the toilet.

  Furthermore, in the setting item F, as a 24-hour ventilation operation mode, the standard 24-hour ventilation air volume (for example, 0.5 times / hour of the house ventilation target volume) and the 24-hour ventilation air volume are reduced in winter. The winter mode (for example, 0.4 times / hour of the volume to be ventilated in the house) can be selected.

  The setting items shown in Table 1 and Table 2 are examples, and the present invention is not limited to this.

  When the setting button 43a is pressed after shifting to the setting mode, the control unit 71 switches the setting items whose setting values can be changed in the operation setting information in order from the left side shown in Table 1, and displays the display unit 46. The alphabet specifying the selected setting item is displayed at the hour position H.

  Thereby, using the setting button 43a, it is possible to shift to the setting mode and select a setting item for changing the setting value.

  In the setting mode, when the up / down button 44 of the operation unit 41A is pressed, the control unit 71 sequentially switches the setting codes shown in Table 2 according to the selected setting item, and displays the amount of the display unit 46. The selected setting code is displayed at the position M.

  Thus, the set value can be changed using the up / down button 44 used for setting the timer.

  In the setting mode, when the determination button 43 b is pressed, the control unit 71 determines the setting value selected by the setting button 43 a and changed by the up / down button 44. In order to confirm the user who has changed the setting value, the alphabet and setting code of the determined setting item are displayed on the display unit 46 for a predetermined time, for example, 10 seconds, and then the normal display is restored.

  Thereby, the user can recognize reliably that the content of the changed setting and the setting were changed.

  The switched setting value is stored in the memory 71a, and the control unit 71 reads the corresponding setting value from the memory 71a from the memory 71a according to the operation mode, and executes the selected operation mode. The set value is stored even when a reset button (not shown) is pressed or a power failure occurs.

  The present invention is applied to a bathroom air conditioner that is installed in a bathroom and has functions of ventilating the bathroom and other rooms outside the bathroom and heating the bathroom.
