<Installation example of bathroom air conditioner>
FIG. 8 is a configuration diagram illustrating an installation example of the bathroom air conditioner 1 according to the present embodiment. The bathroom air conditioner 1 is installed on the ceiling of the bathroom 31. The ceiling panel of the bathroom 31 is formed with an opening for receiving the main body case 4 of the bathroom air conditioner 1 described in FIG. 1 and the like, and the bathroom air conditioner 1 is suspended from the ceiling so that the front panel 17 is exposed. It is attached in the form of being lowered or fixed to the ceiling panel.

  The operation unit 22 shown in FIG. 7 and the like is attached to the wall surface of the bathroom dressing room 32 adjacent to the bathroom 31, and is connected to the bathroom air conditioner 1 by a cable, for example.

  In the bathroom air conditioner 1 attached to the ceiling of the bathroom 31, the intake duct 33 is connected to the intake duct connection unit 15. The air intake duct 33 is connected to an air intake grill 33 a attached to the ceiling of the bathroom undressing place 32, and is configured such that the bathroom air conditioner 1 can intake air from the bathroom undressing place 32 and the like.

  In addition, a bathroom door 34 is provided at the entrance of the bathroom 31, and an air intake 34 (Garari) 34 a is provided at the bathroom door 34, so that the air from the washroom 32 and the like can be taken into the bathroom 31.

  Further, in the bathroom air conditioner 1 attached to the ceiling of the bathroom 31, the exhaust duct 35 is connected to the exhaust duct connection portion 16. The exhaust duct 35 is connected to an exhaust grill 35a attached to an outer wall 36 of a building (not shown), and the air in the bathroom 31 and the like sucked from the bathroom suction grill 17b of the bathroom air conditioner 1 and the intake grill 33a and the intake duct 33. The air that has been sucked into the bathroom undressing room 32 and the like can be exhausted to the outside via the exhaust duct 35.

  Since the bathroom air conditioner 1 also has a function of drying laundry or the like, the bathroom 31 includes a land re-pipe 37 for hanging the laundry or the like.

  The bathroom air conditioner 1 switches the direction in which the wind spreads by operating the wind direction switching louver 7 shown in FIG. 1 or the like according to the operation mode to be executed, according to the operation mode to be executed.

  Here, when the wind blown out from the bathroom blowing grill 17a of the bathroom air conditioner 1 directly hits a bather who comes out of the bathtub 31a and is in the washing place 31b, cold air may be felt.

  For this reason, the wind direction switching louver 7 is set so that the air blowing direction from the bathroom blowing grill 17a is the washing area 31b direction in the preheating mode in which the bathroom 31 itself is warmed before bathing, and the direction of the land re-pipe 37 in the other operation modes. It may be switched by the operation.

<Operation example of wind direction switching louver>
FIG. 9 is an explanatory diagram showing an operation example of the wind direction switching louver 7. First, the operation of the wind direction switching louver 7 of the bathroom air conditioner 1 of the present embodiment will be described. In the wind direction switching louver 7, as shown in FIG. 9A, the first opening 8 a faces downward when the second opening 8 b of the air passage forming body 8 faces the outlet 5 b. One rectifying plate group 9L is inclined in a direction in which the lower end faces outward. The other rectifying plate group 9R is inclined in the direction opposite to that of the one rectifying plate group 9L, and the lower end faces outward.

  Thereby, the air blown from the outlet 5b by the operation of the circulation fan 2 flows according to the direction of the inclination of the rectifying plate 9, so that the air path is expanded. Therefore, wind blows out from the bathroom blowing grill 17a of the bathroom air conditioner 1 over a wide range. Thus, the blowing direction of the air for blowing the wind over a wide range from the bathroom blowing grill 17a is referred to as wide.

  From the state shown in FIG. 9 (a), the air passage forming body 8 is rotated 180 degrees about the shaft 10 by the louver motor 11, and the first opening of the air passage forming body 8 is shown in FIG. 9 (b). Assuming that the portion 8a faces the air outlet 5b, the second opening portion 8b faces downward, and thus one rectifying plate group 9L is inclined in a direction in which the lower end faces inward. The other rectifying plate group 9R is inclined in the opposite direction to the one rectifying plate group 9L, and the lower end faces inward.

  Thereby, the air blown out from the blower outlet 5b by the operation of the circulation fan 2 flows according to the direction of the inclination of the rectifying plate 9, thereby narrowing the air path. Therefore, wind blows out from the bathroom blowing grill 17a of the bathroom air conditioner 1 to a narrow range. Thus, the blowing direction of the air for blowing wind from the bathroom blowing grill 17a to a narrow range is called a spot.

  In the bathroom air conditioner 1 of the present embodiment, it is possible to switch the range in which the wind spreads by switching the direction in which the air is blown by the rotation operation of the air passage forming body 8 without changing the angle of each rectifying plate 9.

  Thereby, a mechanism for operating the individual rectifying plates 9 is not necessary, and the range in which the wind spreads can be switched with a simple configuration.

<Example of operation of bathroom air conditioner of this embodiment>
Next, operation | movement of the bathroom air conditioner 1 of this Embodiment is demonstrated with reference to each figure. FIG. 10 shows a combination pattern of the operation mode of the bathroom air conditioner 1 and the operation of each part. In addition, what is shown in FIG. 9 as an operation mode of the bathroom air conditioner 1 is an example.

  In the table of FIG. 10, whether or not the circulation fan motor 2b and the ventilation fan motor 3b shown in FIG. In addition, the air blowing direction by the wind direction switching louver 7 is set so as to be selectable from the wide or spot direction, and further from the washing area 31b direction or the land re-pipe 37 direction shown in FIG.

  In addition, the heater 12 is also set to be selectable between operation and non-operation for each operation mode.

  When the heating mode button 24 is pressed on the operation unit 22 shown in FIG. 7, the control unit 21 determines that the heating operation mode is selected, and first executes the preliminary heating mode. In the preliminary heating mode, the control unit 21 drives the louver motor 11 so that the air flow direction forming louver 7 causes the air blowing direction to become spots as shown in FIG. 9B. The first opening 8a is oriented to face the outlet 5b. Further, the direction of the air path forming body 8 is controlled so that the air blowing direction is the direction of the washing place 31b shown in FIG. Further, the control unit 21 drives the circulation fan motor 2b and the heater 12.

  When the circulation fan motor 2b is driven, the impeller 2a shown in FIG. 1 and the like rotates, so that the air in the bathroom is sucked from the suction port 5a of the circulation fan 2 through the bathroom suction grille 17b of the front panel 17, The circulation fan case 5 causes air to flow to the outlet 5b.

  When the heater 12 is driven and energized, the air passing through the air passage in the circulation fan case 5 is heated and blown out from the outlet 5 b of the circulation fan case 5. And since the one rectifying plate group 9L and the other rectifying plate group 9R both inwardly incline toward the airflow direction switching louver 7, the airflow direction switching louver 7 is moved from the outlet 5 b by the operation of the circulation fan 2. The blown-out air flows according to the direction of inclination of the rectifying plate 9, thereby narrowing the air path. Therefore, hot air blows out from the bathroom blow grill 17a of the front panel 17 to a narrow area toward the washing place 31b as shown by an arrow W1 in FIG.

  Thereby, in the preliminary heating mode, the bathroom 31 can be locally warmed in winter or the like. Then, by narrowing the air passage and blowing out warm air, the wind speed is increased, and the warm air can reach the floor surface of the washing area 31b to warm the floor surface in a short time.

  When the preheating mode is executed and, for example, a predetermined time has elapsed, the control unit 21 switches the preheating mode to the bathing heating mode. In the bathing heating mode, the control unit 21 drives the louver motor 11 so that the air blowing direction of the air direction switching louver 7 is wide as shown in FIG. 9A. The second opening 8b faces the air outlet 5b. Further, the direction of the air path forming body 8 is controlled so that the air blowing direction is the direction of the land pipe 37 shown in FIG. Further, the control unit 21 drives the circulation fan motor 2b and the heater 12.

  In the bathing heating mode, the wind direction switching louver 7 is blown by the operation of the circulation fan 2 because both the one rectifying plate group 9L and the other rectifying plate group 9R are inclined outwardly. The air blown out from the outlet 5b flows according to the direction of the inclination of the rectifying plate 9, so that the air path is widened. Accordingly, warm air blows out from the bathroom blow grill 17a of the front panel 17 toward the land re-pipe 37 over a wide range as indicated by an arrow W2 in FIG.

  Thereby, in bathing heating mode, the whole bathroom 31 can be warmed in winter. Then, it is possible to prevent the cold air from being felt by expanding the air path and blowing out the warm air to reduce the wind speed so that the warm air does not directly hit the bather.

  In the heating mode, the ventilation fan motor 3b is not driven and ventilation is not performed, so that the air in the bathroom 31 heated in the heating mode is not discharged.

  Here, the air volume of the circulation fan 2 may be changed by changing the number of rotations of the circulation fan motor 2b between the preheating mode and the bathing heating mode. For example, in the preliminary heating mode, the bathroom 31 may be warmed in a shorter time by increasing the air volume of the circulation fan 2. Moreover, it is good also as a structure which performs only the preliminary heating mode as heating operation mode.

  When the cool breeze mode button 25 is pressed on the operation unit 22 shown in FIG. 7, the control unit 21 determines that the cool breeze operation mode is selected, and drives the louver motor 11, the circulation fan motor 2b, and the ventilation fan motor 3b.

  In the cool breeze operation mode, the control unit 21 drives the louver motor 11 so that the air blowing direction of the air direction by the wind direction switching louver 7 becomes a spot as shown in FIG. The first opening 8a is oriented to face the outlet 5b. Further, the direction of the air path forming body 8 is controlled so that the air blowing direction is the direction of the washing place 31b shown in FIG.

  When the circulation fan motor 2 b is driven, the air in the bathroom 31 is sucked into the circulation fan 2 from the bathroom suction grille 17 b of the front panel 17. In the cool air operation mode, since the heater 12 is not driven, the air passing through the circulation fan case 5 is not heated, and blown air (cool air) according to the temperature in the bathroom 31 blows out from the outlet 5b.

  In the cool wind operation mode, the wind direction switching louver 7 is inclined in an inverted C shape with both the one rectifying plate group 9L and the other rectifying plate group 9R facing inward. Therefore, the air blown out from the outlet 5b by the operation of the circulation fan 2 flows in accordance with the direction of the inclination of the rectifying plate 9, so that the bathroom 31 passes from the bathroom outlet grill 17a of the front panel 17 as indicated by an arrow W1 in FIG. Air blows out toward the washing area 31b.

  When the ventilation fan motor 3b is driven, the impeller 3a shown in FIG. 2 rotates to pass from the bathroom suction grille 17b of the front panel 17 through the bathroom ventilation air passage 13a and the suction port 6a of the ventilation fan case 6, Air in the bathroom 31 is sucked into the ventilation fan 3.

  The air sucked from the suction port 6a flows to the outlet 6b by the ventilation fan case 6, passes through the exhaust duct 35 shown in FIG. 8, and is discharged from the exhaust grill 35a to the outside.

  Thereby, in the cool breeze operation mode, the bathroom air conditioner 1 can be used as a fan in summer or the like. That is, since the wind is narrowed and sent to the bather in the washing area 31b, the wind reaches the bather and the bather can coolly take a bath even in summer. In the cool breeze operation mode, the ventilation fan motor 3b is driven to ventilate the air in the bathroom 31 and blow out the air while ventilating the moisture in the bathroom 31. Can do.

  When the drying mode button 27 is pressed on the operation unit 22 shown in FIG. 7, the control unit 21 determines that the drying operation mode is selected, and drives the louver motor 11, the circulation fan motor 2 b, the ventilation fan motor 3 b, and the heater 12. .

  In the dry operation mode, the control unit 21 drives the louver motor 11 so that the air blowing direction of the air direction switching louver 7 is wide as shown in FIG. 9A. The second opening 8b is oriented to face the air outlet 5b. Further, the direction of the air path forming body 8 is controlled so that the air blowing direction is the direction of the land pipe 37 shown in FIG.

  When the circulation fan motor 2b and the heater 12 are driven, the air in the bathroom 31 is sucked into the circulation fan 2 from the bathroom suction grille 17b of the front panel 17, and hot air blows out from the outlet 5b.

  In the dry operation mode, the air direction switching louver 7 is such that both the one rectifying plate group 9L and the other rectifying plate group 9R are inclined outward, so that the air blown out from the outlet 5b by the operation of the circulation fan 2 is By flowing according to the direction of the inclination of the rectifying plate 9, the air path is expanded. Accordingly, warm air blows out from the bathroom blow grill 17a of the front panel 17 toward the land re-pipe 37 over a wide range as indicated by an arrow W2 in FIG.

  When the ventilation fan motor 3b is driven, the impeller 3a shown in FIG. 2 rotates to pass from the bathroom suction grille 17b of the front panel 17 through the bathroom ventilation air passage 13a and the suction port 6a of the ventilation fan case 6, Air in the bathroom 31 is sucked into the ventilation fan 3.

  The air sucked from the suction port 6a flows to the outlet 6b by the ventilation fan case 6, passes through the exhaust duct 35 shown in FIG. 8, and is discharged from the exhaust grill 35a to the outside.

  Thereby, in the dry operation mode, while blowing hot air to the bathroom 31 and discharging the air of the bathroom 31 to the outside, the laundry of clothes dried on the land pipe 37 in the bathroom 31 can be dried. .

  Then, by expanding the air path and blowing out the warm air, the warm air is blown out over a wide range so that the warm air can be applied to the entire clothes hung on the land re-pipe 37, thereby promoting the drying.

  In addition, you may provide the bathroom drying operation mode which dries the wall surface and floor surface of the bathroom 31 as an operation mode. In the bathroom drying operation mode, as shown in FIG. 9 (a), the air passage forming body 8 has the second opening so that the heater 12 is not energized and the air blowing direction by the air direction switching louver 7 is wide. Let the part 8b be the direction which opposes the blower outlet 5b.

  As a result, the circulation fan 2 is driven to blow air from the bathroom blowing grill 17a of the front panel 17 over a wide range, and the air blows against the wall surface of the bathroom 31 so that the wall surface of the bathroom 31 can be dried. .

  Further, as the bathroom drying operation mode, the direction of the air path forming body 8 is switched between the direction shown in FIG. 9A and the direction shown in FIG. When the body 8 is in the direction of FIG. 9A, the air blows against the wall surface of the bathroom 31, and when the air passage forming body 8 is in the direction of FIG. 9B, the air blows against the floor surface of the washing place 31 b of the bathroom 31. Like that.

  Thereby, both the wall surface of the bathroom 31 and the floor surface of the washing place 31b can be dried.

  When the ventilation mode button 26 is pressed on the operation unit 22 shown in FIG. 7, the control unit 21 determines that the ventilation operation mode is selected, and drives the ventilation fan motor 3b. When the ventilation fan motor 3 b is driven, air in the bathroom 31 is sucked into the ventilation fan 3 from the bathroom suction grille 17 b of the front panel 17. Further, the air in the washroom 32 is sucked into the ventilation fan 3 from the intake grill 33a shown in FIG.

  The air sucked into the ventilation fan 3 flows to the outlet 6b by the ventilation fan case 6, passes through the exhaust duct 35, and is discharged from the exhaust grill 35a to the outside.

  Thereby, in ventilation operation mode, the air in the bathroom undressing place 32 in which the bathroom 31 and the intake grille 33a were installed can be discharged | emitted outdoors. In addition, between the bathroom 31 and the bathroom undressing room 32, the air in the bathroom undressing room 32 is also taken into the bathroom 31 from the air intake 34 a of the bathroom door 34, and is discharged outside by the bathroom air conditioner 1.

  Here, the bathroom air conditioner 1 can also constitute a 24-hour ventilation system. That is, the bathroom air conditioner 1 discharges the air in the bathroom undressing room 32 in which the bathroom 31 and the intake grill 33a are installed to the outside from the undercut portion of the door (not shown) of the bathroom undressing room 32, etc. Air is inhaled.

  Thereby, fresh outside air is taken in from the air intake provided in the predetermined room. And the predetermined ventilation frequency | count can be satisfy | filled by setting the air volume of the ventilation fan 3 so that required ventilation air volume may be obtained.

  In the ventilation operation mode, the bathroom blowing grill 17a of the front panel 17 may be closed by the wind direction switching louver 7. For example, the bathroom blowing grill 17a can be closed on the side of the air passage forming body 8 by turning the air passage forming body 8 with the air blowing direction wide or spotted by approximately 90 degrees. Therefore, while the operation of the circulation fan 2 is stopped, the appearance can be improved by closing the bathroom blowing grill 17a.

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