[0005]
[Action]
The laundry is dried so that air easily flows in the bathroom, and the bathroom drying ventilation apparatus 1 is operated. The air blown out from the plurality of outlets 2-2 in the lower circulating centrifugal blower part first flows along the ceiling surface, changes direction and flows along the side wall surface of the room from the ceiling, and is washed in the room. It circulates while promoting the evaporation of water on objects, ceilings and side walls. Further, the clothes are sucked from the circulation suction port 2-1 and the ventilation suction port 3-1 of the bathroom drying ventilation device while drying the laundry. The air sucked from the suction port 2-1 is given kinetic energy by a centrifugal fan for circulation , and blown out from the blowout port 2-2 into the bathroom through the blowout passage 2-4 . Moist air sucked from the suction port 3-1 enters the casing 3-3 through the air passage 3-4, and is subjected to kinetic energy by a centrifugal blower for ventilation. To be discharged.

Reference numeral 7 denotes an attachment member for attaching the bathroom drying ventilation apparatus 1 to the ceiling 8. It is not necessary to be particularly airtight between the rotating shaft 4 and the casing forming the partition wall of the centrifugal fan for circulation, and a gap that does not hinder the rotation may be provided.
[0007]
2 is a cross-sectional view taken along line AA in FIG. 2-3 is a casing in the ventilation fan part, 2-4 is an outlet passage, and 2-5 is an outlet passage wall, which form guide vanes. A suction port 3-1 is provided in a portion surrounded by the blowout passage wall 2-5, the casing 2-3, and the outer shell wall of the bathroom drying ventilation apparatus 1, that is, the guide vane. The circled a indicates the flow of the longitudinal air for circulation in the bathroom. “B” surrounded by a circle indicates the flow of air in the vertical direction for ventilation exhausted to the outside or the like. CC shows the cross-sectional position of FIG.
3 is a cross-sectional view taken along the line BB in FIG. The air sucked from the suction port 3-1 is subjected to kinetic energy by the sirocco fan 3 through the center portion, and is connected to the outside through the blowout port 3-2 and from the duct joint 6 (not shown). ).
[0008]
FIG. 4 is an elevational view of the bathroom drying ventilation apparatus 1.
FIG. 5 is a bottom view showing another example of the circulation fan part. A mesh portion indicates a filter. By making the outer shape of the attachment part of the bathroom drying ventilation device 1 to the ceiling plate circular, the direction of the duct joint 6 can be positioned at any position of 360 degrees as necessary.
FIG. 6 shows an example in which the bathroom drying ventilation apparatus 1 is attached to the ceiling of the bathroom 10. 11 is a window, 12 is a door, 13 is a bathtub, and 14 is a curved surface portion for smoothly moving the air flow along the wall surface. Reference numeral 15 denotes an air intake provided in the door. The air blown out from the air outlet 2-2 flows along the ceiling and further along the side wall, promotes evaporation of the attached water droplets, circulates with such moisture, and is opened outdoors by the ventilation fan part. Exhausted.
[0009]
Air in the bathroom is sucked in from the suction port 2-1, kinetic energy is applied by the turbo fan 2, and blown out along the ceiling 8 from the plurality of blowout ports 2-2 through the blowout passage 2-4. The bathroom drying ventilation apparatus 1 is provided in the center position of the ceiling in FIG. In the embodiment, the number of outlets 2-2 is set to 4, but may be 2 or 3 or 4 or more. When it is provided at the corner or end of the ceiling, the blowing direction is not necessarily omnidirectional. The water droplets adhering to the ceiling or wall surface are promoted to evaporate by the circulating air and circulate along with the air. Such damp air in the bathroom is sucked from the suction port 3-1, kinetic energy is applied by the sirocco fan 3 through the air passage 3-4, and the exhaust air is discharged from the duct joint 6 to the duct communicating with the outside. To do.
In addition, if a heater is attached to the air outlet 2-2 of the circulation fan portion so that warm air is circulated in the bathroom when it is cold such as in winter, comfortable bathing can be performed.
[0010]
【effect】
By removing water droplets adhering to the ceiling and side walls by the air circulating in the bathroom, the inside of the bathroom can be dried more efficiently, and the bathroom can be used as a drying room for laundry or the like. Laundry and the like can be dried without using a heater by generating an air flow along the ceiling where water droplets easily adhere from the plurality of air outlets of the bathroom drying ventilator.
