The ion generator 16 is an example of an ion generating means, and the ion emission surface is exposed in the blowing air path formed by the fan case 11. The ion generator 16 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.

  As a result, the ion generator 16 generates approximately the same number of positive ions and negative ions in conjunction with the rotation of the fan motor 9, thereby supplying approximately the same number of positive ions and negative ions to the bathroom 51. It is possible to remove mold floating bacteria and suppress the occurrence of mold and the like.

In addition, before fixing each unit, the blowout duct 5, the suction duct 6 and the exhaust duct 22 are connected to each suction port or exhaust port on the back surface of the ceiling, and after completing the connection, each unit is connected to each part. You may make it fix. Moreover, as an installation form of each unit, an anchor bolt or the like may be used to hang it on the back of the ceiling (under the upper floor: concrete slab). In this example, the circulation blowing grill 7 and the circulation / ventilation suction grill 8b are arranged in a line. Furthermore, a cover member is attached to a portion of the ceiling surface of the dressing room 52 where the circulation blow grill 7 and the circulation / ventilation suction grill 8b are not installed, and is configured to be substantially flush with the ceiling panel 52b. .

  As described above, according to the method of installing the bathroom air conditioner 100, the bathroom air conditioner capable of performing the air conditioning operation by setting the heating operation mode, the cool air operation mode, or the ventilation operation mode of the bathroom 51 and the dressing room 52 simultaneously or individually. The device 100 can be assembled. Moreover, the blower body 2, the outlet unit 3, and the suction port units 4a and 4b can be constructed from the inspection ports 55a and 55b. Accordingly, the bathroom air conditioner 100 can be easily installed in an assembly (unit bath) type bathroom or the like.

  In addition, the circulation / ventilation suction grill 8a, which is thinner and narrower than the conventional method, is exposed to the bathroom 51, and the circulation blowout grill 7 and the circulation / ventilation suction grill 8b are exposed to the dressing room 52 on the ceiling surface. Just do it. Therefore, it is possible to give the user a refreshing feeling on the ceiling surface. Compared with the case where a conventional central heating system is applied, the air conditioning system can be simplified and the operating cost can be reduced.

  FIG. 7 is a functional block diagram illustrating an example of a control system of the bathroom air conditioner 100.

  The bathroom air conditioner 100 illustrated in FIG. 7 includes a control unit 61 that controls the blower body 2 and the outlet unit 3. The control unit 61 constitutes an example of a control unit, and includes a CPU, a memory, and the like. The control unit 61 is connected to the fan motor 9 and the ion generator 16 that constitute the blower body 2, and to the heater 25, the damper motor 27, the human sensor 46, and the louver motor 49 that constitute the air outlet unit 3. The

  An operation unit 62 constituting an example of a setting unit is connected to the control unit 61, and the control unit 61 is operated to set an operation operation mode. The control unit 61 executes, for example, a heating operation mode, a cool air operation mode, a drying operation mode, and a ventilation operation mode according to a program stored in a memory or the like (not shown). These operation modes are selected by a user such as a bather operating the operation unit 62, and the control unit 61 performs the fan motor 9, the ion generator 16, the heater 25 according to a program for executing the selected operation mode. And controls the damper motor 27 and the like.

  The operation unit 62 is a remote control device that is independent of the bathroom air conditioner body. For example, the operation unit 62 is attached to a wall surface of a bathroom (not shown) adjacent to the bathroom 51 and mounted on the blower body 2 and the like. Connected with electrical cable. In this example, the operation unit 62 is provided with a heating button and a movable louver button (not shown). An operation signal S62 generated by pressing these operation buttons is output to the control unit 61.

  The control unit 61 generates various control signals S9, S16, S25, S27, S49, and S56 based on the entrance detection signal S46 from the human sensor 46 and the operation signal S62 from the operation unit 62, and the blower body 2 and The air outlet unit 3 is controlled. For example, the control unit 61 generates a motor control signal S9 for the blower main body 2 based on the room detection signal S46, the operation signal S62, and the like, and outputs the motor control signal S9 to the fan motor 9 to execute fan control. To do. The fan motor 9 inputs the motor control signal S9 and drives the fan 10. In addition, the control unit 61 generates an ion control signal S16 based on the operation signal S62 for the blower main body 2, and outputs the ion control signal S16 to the ion generator 16 to execute ion generation control. The ion generator 16 receives the ion control signal S16 and generates ions.

  Further, the control unit 61 generates a heater control signal S25 based on the operation signal S62 for the outlet unit 3, and outputs the heater control signal S25 to the heater 25 to execute the heater control. The heater 25 inputs the heater control signal S25 and heats the heater. Further, the control unit 61 generates a damper control signal S27 based on the operation signal S62, and outputs the damper control signal S27 to the damper motor 27 to execute damper motor control. The damper motor 27 inputs the damper control signal S27 and drives the circulation damper 26.

  The controller 61 generates a louver control signal S49 based on the operation signal S62, and outputs the louver control signal S49 to the louver motor 49 to execute louver motor control. The louver motor 49 inputs the louver control signal S49 and drives the rectifying plate 48. The controller 61 generates a damper control signal S56 based on the operation signal S62, and outputs the damper control signal S56 to the damper motor 56 'to execute damper opening / closing control. The damper motor 56 'inputs the damper control signal S56 and drives the damper. Thereby, the heating operation mode, the cool air operation mode, or the ventilation operation mode is set, and the two rooms of the bathroom 51 and the dressing room 52 can be executed simultaneously or individually.

  Note that the human sensor 46 is not necessarily provided. Further, it may be a lighting switch such as the bathroom 51 or the dressing room 52, and this signal may be used as the entrance detection signal S46. The blowing direction of warm air, cool air, etc. can be controlled by the electric louver 47 based on the entrance detection signal S46 from the human sensor 46.

  Then, the operation example of the bathroom air conditioner 100 as an Example is demonstrated. 8 to 11 are conceptual diagrams showing operation examples in each operation mode. In this embodiment, the air conditioner is applied to a sanitary space such as a bathroom and a dressing room, and the operation mode is divided into four modes: heating, cool breeze, drying and ventilation. In this example, the description will be divided into four cases.

<Heating operation mode>
8A to 8C are conceptual diagrams illustrating an operation example in the heating operation mode of the bathroom air conditioner 100 as the first embodiment. The heating operation mode is further divided into three cases: swing (reciprocating movement of the louver 48), bathroom, and dressing room. Table 1 summarizes the three heating operation modes.

  In the heating operation mode, since the circulation damper 26 is in the circulation position in the air outlet unit 3, the air outlet case 17 communicates with the circulation air outlet 24 from the circulation / ventilation inlet 20 connected to the air outlet duct 5. A circulation air passage 28a is formed.

[Swing heating operation mode]
In this example, the door 58 of the entrance / exit of the bathroom 51 shown in FIG. 8A is opened. On the premise of this, when the swing heating operation mode is set by the operation unit 62 shown in FIG. 7, the blower main body 2 sucks the air II of the bathroom 51 through the suction port unit 4a and also through the suction port unit 4b. The air II of the dressing room 52 is sucked in, and the hot air I is alternately blown out to the bathroom 51 and the dressing room 52 using the swing function of the blowout unit 3.

  For example, when the swing heating operation mode is selected by the operation of the operation unit 62, the control unit 61 of the bathroom air conditioner 100 outputs the damper control signal S27, drives the damper motor 27 of the outlet unit 3, and the circulation damper. 26 is closed to the circulating position. Further, the control unit 61 outputs a damper control signal S56 to the damper motor 56 'to execute damper opening / closing control. In the electric damper 56, the damper motor 56 'inputs the damper control signal S56 and opens the damper.

  Then, the control unit 61 outputs a motor control signal S9 to drive the fan motor 9 of the blower main body 2 to rotate the fan 10 in “setting 1: strong operation” and output a heater control signal S25 to blow the fan. The heater 25 of the outlet unit 3 is driven.

  At this time, in the blower body 2, when the fan 10 rotates, the air II is sucked from the fan suction port 11 a of the fan case 11. The air II in the bathroom 51 sucked into the blower main body 2 is blown out from the fan outlet 11 b of the fan case 11 to the outlet unit 3. In the air outlet unit 3, the air II sent into the unit is blown out from the circulation air outlet grill 7 into the bathroom 51 and the dressing room 52 through the circulation air passage 28a.

  Since the heater 25 arranged at the circulation outlet 24 in front of the circulation outlet grill 7 is energized and heated, the air II passing through the circulation outlet 24 is warmed and blown out of the circulation outlet grill 7. . Moreover, since the electric louver part 47 is arrange | positioned at the circulation blowing grill 7, the control part 61 operates this. For example, the control unit 61 outputs a louver control signal S49 to the louver motor 49 to execute louver motor control. The louver motor 49 inputs the louver control signal S49 and drives the rectifying plate 48. Due to the rotational force of the louver motor 49, the rectifying plate 48 is swung left and right with the shaft 48a as a fulcrum. In the following operation mode, this operation is also performed at the initial setting.

  Thereby, in the swing heating operation mode, while the air II inside the bathroom 51 and the dressing room 52 is circulated, the hot air I is alternately blown out to the bathroom 51 and the dressing room 52 to simultaneously heat the bathroom 51 and the dressing room 52. The temperature of the bathroom 51 and the dressing room 52 can be raised. The hot air I blown out into the bathroom 51 and the dressing room 52 is sucked from the suction port units 4a and 4b as the fan 10 rotates. The air 51 in the bathroom 51 and the dressing room 52 sucked in here is sent to the outlet unit 3 through the outlet duct 5 and circulates.

[Bathroom heating operation mode]
Also in this example, the door 58 of the entrance / exit of the bathroom 51 shown in FIG. 8B is opened. On the premise of this, when the bathroom heating operation mode is set by the operation unit 62 shown in FIG. 7, the blower main body 2 sucks the air II of the bathroom 51 through the suction port unit 4a and also through the suction port unit 4b. The air II in the dressing room 52 is sucked in, and the hot air I is blown out toward the bathroom 51 using the swing function of the outlet unit 3.

  For example, when the bathroom heating operation mode is selected by the operation of the operation unit 62, the control unit 61 of the bathroom air conditioner 100 outputs the damper control signal S27, drives the damper motor 27 of the outlet unit 3, and the circulation damper. 26 is closed to the circulating position. In the electric louver unit 47, after setting the bathroom heating operation mode, the control unit 61 outputs a louver control signal S49 to the louver motor 49 to execute louver motor control. The louver motor 49 inputs the louver control signal S49 and drives the rectifying plate 48. In this example, since the louver motor 49 is rotationally driven in the direction of arrow b shown in FIG. 5A, the rectifying plate 48 rotates in the direction of arrow b around the shaft 48a. As a result, the rectifying plate 48 changes its posture in the direction of the bathroom 51 shown in FIG.

  Then, the motor control signal S9 is output to drive the fan motor 9 of the blower main body 2, and the fan 10 is rotated in “setting 1: strong operation”, and the heater control signal S25 is output to output the air outlet unit 3. The heater 25 is driven. At this time, in the blower body 2, when the fan 10 rotates, the air II is sucked from the suction port units 4 a and 4 b into the fan suction port 11 a of the fan case 11. The air II in the bathroom 51 and the dressing room 52 sucked into the blower body 2 is blown out from the fan outlet 11 b of the fan case 11 to the outlet unit 3. In the blowout unit 3, the air II sent into the unit is blown out from the circulation blowout grill 7 toward the bathroom 51 through the circulation air passage 28 a.

  Thereby, in the bathroom heating operation mode, the hot air I can be blown out in the direction of the bathroom 51 while circulating the air II inside the bathroom 51 and the dressing room 52, and the bathroom 51 can be preferentially heated. The temperature of 51 can be raised. The hot air I blown into the bathroom 51 is sucked in from the suction port units 4a and 4b as the fan 10 rotates. The air II in the bathroom 51 sucked in here is sent to the outlet unit 3 through the outlet duct 5 and circulates.

[Dressing room heating operation mode]
In this example, the door 58 of the entrance / exit of the bathroom 51 shown in FIG. 8C is closed. On the premise of this, when the dressing room heating operation mode is set by the operation unit 62 shown in FIG. 7, the blower main body 2 sucks the air II of the dressing room 52 through the suction port unit 4b, The warm air I is blown out toward the dressing room (main room) 52 using the swing function 3.

  For example, when the dressing room heating operation mode is selected by the operation of the operation unit 62, the control unit 61 of the bathroom air conditioner 100 outputs a damper control signal S27, drives the damper motor 27 of the outlet unit 3, and circulates. The damper 26 is closed to the circulating position. In the electric louver unit 47, after setting the dressing room heating operation mode, the control unit 61 outputs a louver control signal S49 to the louver motor 49 to execute louver motor control. The louver motor 49 inputs the louver control signal S49 and drives the rectifying plate 48. In this example, since the louver motor 49 is rotationally driven in the direction of arrow a shown in FIG. 5A, the rectifying plate 48 rotates in the direction of arrow a with the shaft 48a as a fulcrum. As a result, the rectifying plate 48 changes its posture in the direction of the dressing room 52 shown in FIG.

  Then, the motor control signal S9 is output to drive the fan motor 9 of the blower main body 2, and the fan 10 is rotated in “setting 1: strong operation”, and the heater control signal S25 is output to output the air outlet unit 3. The heater 25 is driven. At this time, in the blower body 2, when the fan 10 rotates, the air II is sucked from the suction port unit 4 b into the fan suction port 11 a of the fan case 11. The air II in the dressing room 52 sucked into the blower main body 2 is blown out from the fan outlet 11 b of the fan case 11 to the outlet unit 3. In the blowout unit 3, the air II sent into the unit is blown out from the circulation blowout grill 7 to the dressing room 52 through the circulation air passage 28a.

  Thereby, in the dressing room heating operation mode, while the air II inside the dressing room 52 is circulated, the warm air I can be blown out to the dressing room 52 and the dressing room 52 can be heated exclusively. Can be raised. The hot air I blown out to the dressing room 52 is sucked from the inlet unit 4b as the fan 10 rotates. The air II in the dressing room 52 sucked in here is sent to the outlet unit 3 through the outlet duct 5 and circulates.

<Cool wind driving mode>
[Swing cool wind driving mode]
9A to 9C are conceptual diagrams showing an operation example in the cool breeze operation mode. The cool breeze operation mode is further divided into three cases: swing, bathroom and dressing room. Table 2 summarizes the three cool breeze operation modes.

  In the cool air operation mode, since the circulation damper 26 is located between the circulation position and the ventilation position in the air outlet unit 3, both the air circulation path 28 a and the exhaust air air path 28 b are formed in the air outlet case 17. Yes. The electric damper 56 is in a closed state, and the suction of the air II in the bathroom 51 through the suction port unit 4a is stopped.

[Swing cool wind driving mode]
In this example, the door 58 of the entrance / exit of the bathroom 51 shown in FIG. 9A is opened. On the premise of this, when the swing cool wind operation mode is set by the operation unit 62 shown in FIG. 7, the blower main body 2 sucks in the air II of the dressing room 52 through the suction port unit 4b, and the blowout unit 3 The cool air III is alternately blown out to the bathroom 51 and the dressing room 52 by using the swing function.

  For example, when the swing cool air operation mode is selected by the operation in the operation unit 62, the control unit 61 of the bathroom air conditioner 100 outputs the damper control signal S27, drives the damper motor 27 of the outlet unit 3, and the circulation damper. 26 is closed to the circulating position. Further, the control unit 61 outputs a damper control signal S56 to the damper motor 56 'of the electric damper 56 to execute damper opening / closing control. In the electric damper 56, the damper motor 56 'inputs the damper control signal S56 and closes the damper.

  And the motor control signal S9 is output, the fan motor 9 of the air blower main body 2 is driven, and the fan 10 is rotated by "setting 1: strong operation". In this mode, the heater 25 of the outlet unit 3 is not driven. At this time, in the blower body 2, when the fan 10 rotates, the air II is sucked from the fan suction port 11 a of the fan case 11. The air II in the dressing room 52 sucked into the blower main body 2 is blown out from the fan outlet 11 b of the fan case 11 to the outlet unit 3. In the air outlet unit 3, the air II sent into the unit is alternately blown out from the circulation air outlet grill 7 into the bathroom 51 and the dressing room 52 through the circulation air passage 28a.

  For example, in the circulation blow-out grill 7, the louver motor 49 operates based on the louver control signal S49 input from the control unit 61. The louver motor 49 inputs the louver control signal S49 and drives the rectifying plate 48. Due to the rotational force of the louver motor 49, the rectifying plate 48 is swung left and right with the shaft 48a as a fulcrum.

  Thus, in the swing cool wind operation mode, while the air II inside the bathroom 51 and the dressing room 52 is circulated, the cool air III is alternately blown out to the bathroom 51 and the dressing room 52, and the bathroom 51 and the dressing room 52 are simultaneously heated. A cool breeze can be blown by blowing air without energizing 25, and the current temperatures of the bathroom 51 and the dressing room 52 can be maintained. The cool breeze III blown out to the bathroom 51 and the dressing room 52 is sucked from the inlet unit 4b as the fan 10 rotates. The air II in the dressing room 52 sucked in here is sent to the outlet unit 3 through the outlet duct 5 and circulates.

[Bathroom cool breeze operation mode]
Also in this example, the door 58 of the entrance / exit of the bathroom 51 shown in FIG. 9B is opened. On the premise of this, when the bathroom cool breeze operation mode is set by the operation unit 62 shown in FIG. 7, the blower main body 2 sucks the air II of the dressing room 52 through the suction port unit 4b, and the air outlet unit 3 The cool air III is blown out in the direction of the bathroom 51 using the swing function.

  For example, when the bathroom cool air operation mode is selected by the operation in the operation unit 62, the control unit 61 of the bathroom air conditioner 100 outputs the damper control signal S27, drives the damper motor 27 of the outlet unit 3, and the circulation damper. 26 is closed to the circulating position. In the electric louver unit 47, after setting the bathroom cool breeze operation mode, the control unit 61 outputs a louver control signal S49 to the louver motor 49 to execute louver motor control. The louver motor 49 inputs the louver control signal S49 and drives the rectifying plate 48. In this example, since the louver motor 49 is rotationally driven in the direction of arrow b shown in FIG. 5A, the rectifying plate 48 rotates in the direction of arrow b around the shaft 48a. As a result, the rectifying plate 48 changes its posture in the direction of the bathroom 51 shown in FIG.

  And the motor control signal S9 is output, the fan motor 9 of the air blower main body 2 is driven, and the fan 10 is rotated by "setting 1: strong operation". In this example, the heater 25 of the outlet unit 3 is not driven. At this time, in the blower body 2, when the fan 10 rotates, the air II is sucked from the suction port unit 4 b into the fan suction port 11 a of the fan case 11. The air II in the dressing room 52 sucked into the blower main body 2 is blown out from the fan outlet 11 b of the fan case 11 to the outlet unit 3. In the blowout unit 3, the air II sent into the unit is blown out from the circulation blowout grill 7 toward the bathroom 51 through the circulation air passage 28 a.

  Thereby, in the bathroom cool breeze operation mode, while circulating the air II inside the bathroom 51 and the dressing room 52, the cool breeze III is blown out in the direction of the bathroom 51, and the bathroom 51 can be focused on a cool breeze environment. The current temperature of the bathroom 51 can be maintained at the temperature of the dressing room 52. The cool breeze III blown out into the bathroom 51 is sucked in from the inlet unit 4 b by the rotation of the fan 10, and the air II in the dressing room 52 sucked in here is sent into the outlet unit 3 through the outlet duct 5. Circulate.

[Changing room cool breeze operation mode]
In this example, the door 58 of the entrance / exit of the bathroom 51 shown in FIG. 9C is closed. On the premise of this, when the dressing room cool breeze operation mode is set by the operation unit 62 shown in FIG. 7, the blower main body 2 sucks the air II of the dressing room 52 through the suction port unit 4b, and the air outlet unit The cool air III is blown out toward the dressing room 52 using the swing function 3.

  For example, the control unit 61 of the bathroom air conditioner 100 outputs a damper control signal S27 and drives the damper motor 27 of the outlet unit 3 to circulate when the dressing room cool breeze operation mode is selected by the operation in the operation unit 62. The damper 26 is closed to the circulating position. In the electric louver unit 47, after setting the dressing room cool breeze operation mode, the control unit 61 outputs a louver control signal S49 to the louver motor 49 to execute louver motor control. The louver motor 49 inputs the louver control signal S49 and drives the rectifying plate 48. In this example, since the louver motor 49 is rotationally driven in the direction of arrow a shown in FIG. 5A, the rectifying plate 48 rotates in the direction of arrow a with the shaft 48a as a fulcrum. As a result, the rectifying plate 48 changes its posture in the direction of the dressing room 52 shown in FIG.

  And the motor control signal S9 is output, the fan motor 9 of the air blower main body 2 is driven, and the fan 10 is rotated by "setting 1: strong operation". The heater 25 of the outlet unit 3 is not driven. At this time, in the blower body 2, when the fan 10 rotates, the air II is sucked from the suction port unit 4 b into the fan suction port 11 a of the fan case 11. The air II in the dressing room 52 sucked into the blower main body 2 is blown out from the fan outlet 11 b of the fan case 11 to the outlet unit 3. In the blowout unit 3, the air II sent into the unit is blown out from the circulation blowout grill 7 to the dressing room 52 through the circulation air passage 28a.

  Thereby, in the dressing room cool wind driving mode, while the air II inside the dressing room 52 is circulated, the cool wind III can be blown out to the dressing room 52, and the dressing room 52 can be exclusively used as a cool wind environment. Temperature current can be maintained. In the cool breeze III blown out to the dressing room 52, the air II in the dressing room 52 sucked from the suction port unit 4b by the rotation of the fan 10 is sent to the blowout unit 3 through the blowout duct 5 and circulates. Further, a part of the air II sent to the outlet unit 3 passes through the exhaust air passage 28b and is discharged to the outside from the exhaust duct 22. Furthermore, the air II in the bathroom 51 is discharged to the outside, so that the air II is sucked into the dressing room 52 from an air inlet provided in a bathroom door (not shown) or the like.

<Dry operation mode>
The dry operation mode is further divided into three cases: swing, bathroom and dressing room. Table 3 summarizes the three drying operation modes. In this example, the dressing room drying operation mode will be described.

In the drying operation mode, since the circulation damper 26 is located between the ventilation position and the circulation position in the outlet unit 3, both the circulation air passage 28 a and the exhaust air passage 28 b are formed in the air outlet case 17. The electric damper 56 is in a closed state, and the suction of the air II in the bathroom 51 through the suction port unit 4a is stopped.
[Dressing room drying operation mode]
FIG. 10 is a conceptual diagram showing an operation example in the dressing room drying operation mode. In this example, the door 58 of the entrance / exit of the bathroom 51 shown in FIG. 10 is closed. On the premise of this, when the dressing room drying operation mode is set by the operation unit 62 shown in FIG. 7, the blower main body 2 sucks the air II of the dressing room 52 through the suction port unit 4b, The warm air I is blown out toward the dressing room 52 using the swing function 3.

  For example, when the dressing room drying operation mode is selected by the operation of the operation unit 62, the control unit 61 of the bathroom air conditioner 100 outputs the damper control signal S27, drives the damper motor 27 of the outlet unit 3, and circulates. The damper 26 is semi-closed (half-opened) so as to be between the ventilation position and the circulation position. In the electric louver unit 47, after setting the dressing room drying operation mode, the control unit 61 outputs a louver control signal S49 to the louver motor 49 to execute louver motor control. The louver motor 49 inputs the louver control signal S49 and drives the rectifying plate 48. In this example, since the louver motor 49 is rotationally driven in the direction of arrow a shown in FIG. 5A, the rectifying plate 48 rotates in the direction of arrow a with the shaft 48a as a fulcrum. As a result, the rectifying plate 48 changes its posture in the direction of the dressing room 52 shown in FIG.

  Then, the motor control signal S9 is output to drive the fan motor 9 of the blower body 2 to rotate the fan 10, and the heater control signal S25 is output to drive the heater 25 of the outlet unit 3. At this time, in the blower main body 2, when the fan 10 rotates in “setting 1: strong operation”, the air II is sucked from the suction port unit 4 b into the fan suction port 11 a of the fan case 11. The air II in the dressing room 52 sucked into the blower main body 2 is blown out from the fan outlet 11 b of the fan case 11 to the outlet unit 3. In the blowout unit 3, the air II sent into the unit is blown out from the circulation blowout grill 7 to the dressing room 52 through the circulation air passage 28a.

  As a result, in the dressing room drying operation mode, while the air II inside the dressing room 52 is circulated, the warm air I is blown out to the dressing room 52 so that the dressing room 52 can be made exclusively like a drying room. The temperature at the point 52 can be raised. The hot air I blown out to the dressing room 52 is sucked from the inlet unit 4b as the fan 10 rotates. The air II in the dressing room 52 sucked in here is sent to the outlet unit 3 through the outlet duct 5 and circulates.

  Further, a part of the air II sent to the outlet unit 3 passes through the exhaust air passage 28b and is discharged to the outside from the exhaust duct 22. Further, the air II in the dressing room 52 is discharged to the outside, so that the air II is sucked into the dressing room from an air inlet (louver) provided in a dressing room door or the like (not shown). Thereby, in the drying operation mode, the hot air I can be blown into the dressing room 52, and the laundry hung on a clothes drying member such as a land pipe (not shown) can be dried. In addition, since a part of the air II in the dressing room 52 is exhausted to the outside and is ventilated, moisture and the like can be discharged to promote the drying of the laundry.

<Ventilation mode>
11A and 11B are conceptual diagrams illustrating an operation example in the ventilation operation mode. The ventilation operation mode is divided into three cases: normal ventilation, 24-hour ventilation, and clean ventilation. Clean ventilation is further divided into three parts: swing, bathroom and dressing room. Table 4 summarizes the five ventilation modes. In this example, normal ventilation, 24-hour ventilation, and clean ventilation operation modes will be described.

  In the ventilation operation mode, since the circulation damper 26 is in the ventilation position in the outlet unit 3, an exhaust air passage 28 b is formed in the outlet case 17. The electric damper 56 is in an open state, and the air II in the bathroom 51 is sucked through the suction port unit 4a.

<Normal ventilation mode>
In this example, the door 58 of the entrance / exit of the bathroom 51 shown to FIG. 11A is opened. On the premise of this, when the ventilation operation mode is set by the operation unit 62 shown in FIG. 7, the blower main body 2 sucks the air II of the bathroom 51 through the suction port unit 4a and also through the suction port unit 4b. The air II in the dressing room 52 is sucked and exhausted to the outside through the outlet unit 3 and the ventilation duct 22.

  For example, when the normal ventilation operation mode is selected by the operation in the operation unit 62, the control unit 61 of the bathroom air conditioner 100 outputs the damper control signal S27 and drives the damper motor 27 of the outlet unit 3. The circulation damper 26 is set to the ventilation position. The controller 61 outputs a motor control signal S9 to the fan motor 10 of the blower main body 2 to execute fan control. The fan motor 9 inputs the motor control signal S9 and drives the fan 10.

  And the fan motor 9 of the air blower main body 2 is driven, and the fan 10 is rotated by "setting 2: medium operation". In the ventilation operation mode, the heater 25 of the outlet unit 3 is not driven. When the fan 10 rotates in the blower body 2, the air II is sucked from the fan suction port 11 a of the fan case 11. As described above, since the fan suction port 11a communicates with the suction port unit 4a and the suction port unit 4b of the dressing room 52 through the suction duct 6, the air blower main body 2 circulates and ventilates the suction port unit 4a. From the suction grill 8a, the air II in the bathroom 51 is sucked into the blower main body 2 through the suction duct 6, and the air II in the dressing room 52 is drawn from the circulation / ventilation suction grill 8b of the suction port unit 4b. The air is sucked into the blower main body 2 via.

  The air II in the bathroom 51 and the dressing room 52 sucked into the blower body 2 is blown out from the fan outlet 11 b of the fan case 11. As described above, the air blower main body 2 has the air outlet 11b in communication with the air outlet unit 3 through the air outlet duct 5, and therefore the air 51 in the bathroom 51 and the dressing room 52 sucked in from the air inlet unit 4. Is sent to the outlet unit 3 through the outlet duct 5.

  In the ventilation operation mode, since the circulation damper 26 is in the ventilation position in the outlet unit 3, the ventilation case 17 communicates with the ventilation outlet 21 from the circulation / ventilation inlet 20 connected to the outlet duct 5. An exhaust air passage 28b is formed.

  Thereby, the air II sent into the blower outlet unit 3 passes the exhaust air path 28b, and is discharged | emitted from the exhaust duct 22 to the outdoors. Further, the air II in the bathroom 51 is discharged to the outside, so that the air II in the dressing room 52 is sucked from an air intake port provided in a door or the like of the dressing room 52 (not shown). Accordingly, in the ventilation operation mode, steam in the bathroom 51 and moisture in the dressing room 52 are discharged to suppress condensation and the like, thereby suppressing generation of mold.

<24 hour ventilation mode>
Also in this example, the door 58 of the entrance / exit of the bathroom 51 is opened as shown in FIG. 11A. On the premise of this, when the 24-hour ventilation operation mode is set by the operation unit 62 shown in FIG. 7, the air blower main body 2 sucks the air II of the bathroom 51 through the suction port unit 4a, and also the suction port unit. The air II in the dressing room 52 is sucked in through 4 b and exhausted to the outside through the outlet unit 3 and the ventilation duct 22.

  The difference from the normal ventilation operation mode is that the fan motor 9 of the blower main body 2 is driven by “setting 3: weak operation” to rotate the fan 10. In this way, the ventilation operation can be executed all day. Others are the same as those in the normal ventilation operation mode, and the description thereof is omitted.

<Clean ventilation operation mode>
In this example, the door 58 of the entrance / exit of the bathroom 51 shown in FIG. 11B is opened. On the premise of this, when the clean ventilation operation mode is set by the operation unit 62 shown in FIG. 7, the blower main body 2 sucks the air II of the bathroom 51 through the suction port unit 4a and also uses the suction port unit 4b. The air II in the dressing room 52 is sucked in through the air outlet and part thereof is exhausted to the outside through the air outlet unit 3 and the ventilation duct 22. When the clean ventilation operation mode is set, the electric louver unit 47 swings the rectifying plate 48 left and right with the shaft 48a as a fulcrum by the rotational force of the louver motor 49. The air outlet unit 3 is configured to blow out the air IV including the positive ions and the negative ions to the bathroom 51 and the dressing room 52 using the swing function and the ion generation function.

  For example, in the clean ventilation operation mode, when the clean ventilation operation mode is selected by the operation of the operation unit 62, the control unit 61 outputs the damper control signal S27, drives the damper motor 27 of the outlet unit 3, and the circulation damper. 26 is in a half-open state, and the damper is placed between the ventilation position and the circulation position. Further, the control unit 61 outputs a damper control signal S56 to the damper motor 56 'to execute damper opening / closing control. In the electric damper 56, the damper motor 56 'inputs the damper control signal S56 and opens the damper.

  Then, the motor control signal S9 is output to drive the fan motor 9 of the blower main body 2 to rotate the fan 10 in “setting 1: strong operation” and to drive the ion generator 16. At this time, the control unit 61 outputs an ion control signal S16 to the ion generator 16 to execute ion generation control. The ion generator 16 receives the ion control signal S16 and generates both positive ions and negative ions. Even in the clean ventilation operation mode, the heater 25 of the outlet unit 3 is not driven.

  When the fan 10 rotates in the blower main body 2, the electric damper 56 is in an open state, so that the air II in the bathroom 51 passes through the suction duct 6 from the circulation / ventilation suction grill 8 a of the suction port unit 4 a. It is sucked into the blower body 2. Further, air II in the dressing room 52 is sucked into the blower main body 2 through the suction duct 6 from the circulation / ventilation suction grille 8b of the suction port unit 4b. The air 51 in the bathroom 51 and the dressing room 52 sucked into the blower main body 2 is sent into the outlet unit 3 through the outlet duct 5.

  In the clean ventilation operation mode, since the circulation damper 26 is in the circulation ventilation position in the outlet unit 3, both the circulation air path 28a and the exhaust air path 28b are formed in the air outlet case 17. Thereby, a part of the air II sent into the blowout unit 3 is blown out from the circulation blowout grill 7 into the bathroom 51 through the circulation air passage 28a. And since both the positive ion and the negative ion are supplied to the air II sent into the blower outlet unit 3 by the ion generator 16, the bathroom 51 and the dressing room 52 contain substantially the same number of positive ions and negative ions. Air IV is blown out.

  Further, a part of the air II sent to the outlet unit 3 passes through the exhaust air passage 28b and is discharged to the outside from the exhaust duct 22. Furthermore, the air II in the bathroom 51 is discharged to the outside, so that the air II is sucked into the dressing room 52 from an air intake port provided in the dressing room 52 (not shown).

  Thus, in the clean ventilation operation mode, while ventilating the bathroom 51 and the dressing room 52, the substantially the same number of positive ions and negative ions are generated in conjunction with the operation of the fan unit 32, and approximately the same number of positive ions and negative ions are generated. By blowing air IV containing ions, it is possible to remove both the floating bacteria contained in the circulating air II and the floating bacteria in the air of the bathroom 101 shown in FIG. . In addition, since the air IV containing both positive ions and negative ions is blown out into the dressing room 52 where the clothes and the like are hung, the growth of mold bacteria in the clothes and the like can be prevented.

  Thus, according to the bathroom air conditioner 100 as the first embodiment, the blower main body 2 installed on the back surface of the ceiling of the bathroom 51 or the dressing room 52 is on the back surface of the ceiling panel of the bathroom 51 and the dressing room 52. The suction port units 4a and 4b are connected to each other through the suction duct 6 and are connected to the blowout port unit 3 through the blowout duct 5 so as to circulate and blow the air II. The inlet units 4a and 4b perform intake and circulation ventilation based on operation operation modes such as heating, cool breeze, drying, and ventilation, and the outlet unit 3 blows out hot air I or cool breeze III.

  Accordingly, the two rooms of the bathroom 51 and the dressing room 52 can be air-conditioned by setting the heating operation mode, the cool air operation mode, the ventilation operation mode, etc. simultaneously or individually. Thereby, sanitary spaces, such as the bathroom 51 and the dressing room 52, can be maintained in a comfortable environment.

  In this embodiment, the first room is the bathroom 51 and the second room is the dressing room 52, but the first room may be the dressing room 52 and the second room may be the bathroom 51. The bathroom 51 here includes a shower room without a bathtub, and the dressing room 52 includes a washroom. By using the present invention, these sanitary spaces can be maintained in a comfortable environment. Of course, the operation operation mode is not limited to the heating operation mode, the cool air operation mode, the ventilation operation mode, or the like.

  The present invention is extremely suitable when applied to a bathroom or a bathroom ventilation drying heater that is installed in a sanitary space such as a dressing room, a shower room, and a washroom, and performs ventilation, ventilation, cool air, and the like of these spaces.
