Abstract

PROBLEM TO BE SOLVED: To more efficiently dry a bathroom by providing centrifugal blower parts in upper and lower parts, providing a plurality of blowout holes in the lower circulating blower part so as to blow air along a ceiling, and forming the suction port of the upper ventilating blower part in the guide glade of the lower blower part. SOLUTION: When a bathroom drying ventilating device 1 provided in the central position of a bathroom is operated, the air in the bathroom is sucked through a suction port 2-1, and a kinetic energy is added thereto by a turbo fan 2, whereby the resulting air is blown out along a ceiling 8 from a plurality of blowout ports 2-2 through a blowout passage. The water drop adhering to the ceiling or wall surface is urged to evaporate by the circulating air, and circulated according to this air. The air in the bathroom is sucked from a suction port 3-1, and a kinetic energy is added by a scirocco fan 3 through an air passage 3-4, whereby the resulting air is discharged to the outside through a duct 6. A heater is mounted on the blowout port 2-2 to circulate hot air in the bathroom in winter, a comfortable bathing can be performed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drying and ventilating apparatus for using a bathroom or similar room as a drying room for laundry or the like.

[0002]

2. Description of the Related Art A conventional drying and ventilating apparatus dries laundry and the like by circulating warm air in a bathroom.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to dry laundry or the like placed in a bathroom or similar room without heating the air circulating in the room.

[0004]

The drying and ventilating apparatus of the present invention is provided with the same or different centrifugal blower portions on the upper and lower sides, fixing the impellers on the same rotating shaft, and lowering the centrifugal blower portion on the lower side. Are provided so that air is blown out along the ceiling, and the suction port of the upper ventilation centrifugal blower portion is formed in the guide blade of the lower circulation centrifugal blower portion.

[0005]

The laundry is dried so that air can easily flow through the bathroom, and the bathroom drying / ventilating apparatus 1 is operated. The air blown out from the plurality of outlets 2-2 of the lower circulating centrifugal blower portion first flows along the ceiling surface, changes the direction, flows along the side wall surface of the room from the ceiling, and performs washing in the room. Circulates while promoting the evaporation of water from objects, ceiling and side walls. Also, while drying the laundry and the like, it is sucked from the suction port 2-1 for circulation and the suction port 3-1 for ventilation of the bathroom drying ventilation apparatus. The air sucked from the inlet 2-1 is applied with kinetic energy by a circulating centrifugal blower and is blown out from the outlet 2-2. The humid air sucked from the inlet 3-1 is applied with kinetic energy by a centrifugal blower for ventilation, and is discharged outside through the duct joint 6.

FIG. 1 is a sectional view of a drying and ventilating apparatus 1 for a bathroom according to the present invention. a shows a flow of air circulating in the bathroom. b shows the flow of air for ventilation. 2 is a centrifugal blower blade for circulating in the bathroom, for example, a turbo fan. 2-1 is a suction port for the circulating centrifugal blower part, and 2-2 is an air outlet. 3 is a centrifugal blower blade for ventilation, for example, a sirocco fan.
3-1 is a suction port for a ventilation blower part. 3
-3 is a casing in a ventilation fan part, 3-4
Is an air passage, and 3-5 is an air passage wall. Reference numeral 4 denotes a rotating shaft, and reference numeral 5 denotes a motor. Reference numeral 6 denotes a duct joint, which is connected to a duct (not shown) and communicates with the outside.
Reference numeral 7 denotes an attachment member for attaching the bathroom drying / ventilating apparatus 1 to the ceiling 8. There is no particular need to make the airtight between the rotary shaft 4 and the casing forming the partition wall of the circulating centrifugal blower, and a gap that does not hinder rotation may be provided.

FIG. 2 is a sectional view taken along the line AA in FIG. 2-3 is a casing in a ventilation blower portion,
2-4 is a blowing passage, and 2-5 is a blowing passage wall, forming a guide blade. A suction port 3-1 is provided in a portion surrounded by the outlet passage wall 2-5, the casing 2-3, and the outer shell wall of the bathroom drying / ventilating apparatus 1, that is, the guide blade. The circled “a” indicates a vertical air flow for circulation in the bathroom. The circled “b” indicates the flow of vertical air for ventilation exhausted outside or the like. C-
C has shown the cross-sectional position of FIG. FIG. 3 is a sectional view taken along line BB in FIG. The air sucked in from the suction port 3-1 is applied with kinetic energy by the sirocco fan 3 through the central portion, passes through the air outlet 3-2, and communicates with the outside from the duct joint 6 (not shown). )
Exhausted.

FIG. 4 is an elevational view of the bathroom drying and ventilating apparatus 1. FIG. 5 is a bottom view showing another example of the circulation blower portion. The mesh indicates a filter. By making the outer shape of the portion particularly attached to the ceiling plate of the bathroom drying and ventilating apparatus 1 circular, the direction of the duct joint 6 can be positioned at any position of 360 degrees as required when it is attached. FIG. 6 shows an example in which the bathroom drying / ventilating apparatus 1 is attached to the ceiling of a bathroom 10. 11 is a window, 12 is
The door, 13 is a bathtub, and 14 is a curved portion for smoothly flowing the air along the wall surface. Fifteen
Is an air inlet provided in the door. The air blown out from the outlet 2-2 flows along the ceiling, further flows along the side walls, promotes evaporation of the attached water droplets, circulates with such moisture, and is outdoors by the ventilation blower portion. Exhausted.

The air in the bathroom is sucked in from the inlet 2-1 and kinetic energy is applied by the turbo fan 2, and is blown out along the ceiling 8 from the plurality of outlets 2-2 through the outlet passages 2-4. Is done. The bathroom drying / ventilating apparatus 1 is provided at the center position of the ceiling in FIG. In the embodiment, the outlet 2
Although the number of 2 is set to 4, it may be 2 or 3 or 4 or more. In the case of being provided at a corner or end of a ceiling, the blowing direction is not necessarily omnidirectional. Water droplets adhering to a ceiling, a wall surface or the like are urged to evaporate by the circulating air and circulate with the air. Such humid air in the bathroom is sucked in from the inlet 3-1 and kinetic energy is applied by the sirocco fan 3 through the air passage 3-4, and is discharged from the duct joint 6 to a duct communicating with the outside. To do it. If a heater is attached to the outlet 2-2 of the circulating blower to circulate warm air into the bathroom when it is cold in winter or the like, comfortable bathing can be performed.

[0010]

[Effect] By removing water droplets attached to the ceiling and the side wall by the air circulating in the bathroom, the bathroom can be dried more efficiently, and the bathroom can be used as a drying room for laundry and the like. By causing the flow of air along the ceiling to which water droplets easily adhere from the plurality of air outlets of the bathroom drying and ventilating apparatus, laundry and the like can be dried without using a heater.
