Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ventilating dryer for a bathroom which is attached to a ceiling surface of a bathroom and ventilates the inside of the bathroom through a duct communicating with the outdoors.
[0002]
[Prior art]
In recent years, demand for ventilation dryers for bathrooms has been increasing in apartment buildings for the purpose of drying clothes and preventing mold on bathroom walls. The bathroom ventilation dryer used in the bathroom is generally mounted on the ceiling surface and exhausts the humidity of the bathroom, but the condensed water generated when this moisture is discharged does not fall from the bathroom ventilation dryer body. Is desired.
[0003]
Conventionally, a duct ventilation fan similar to this type of bathroom ventilation dryer is known as described in the publicity of utility model registration publication No. 2500844.
[0004]
The duct ventilation fan will be described below with reference to FIG.
As shown in the figure, an electric motor 104 is fixed downward on the top surface of a box-shaped main body 103 having an opening 101 on the lower surface and an exhaust port 102 on one side surface, and a blade 105 is provided. A rib 106 serving as a downward projection is provided, a partition plate 107 that vertically partitions the inside of the main body 103 below the blades 105 in the main body 103, a rising portion 109 is provided around the suction port 108, and an opening on the lower surface of the main body 103 is provided. The unit 101 was provided with a decorative panel 110.
[0005]
When the duct ventilation fan is installed and operated in the bathroom, condensed water is generated in the blades 105 through which moisture containing moisture passes in the bathroom and the main body 103 around the blades 105, and the condensed water is formed on the partition plate 107. As the amount increased, the amount of water droplets swept away by the ribs 106 provided on the blades 105 and fine water droplets were discharged out of the room along with the exhaust by the blades 105.
[0006]
[Problems to be solved by the invention]
In such a conventional ventilating fan for ducts, the rib 106 for scattering the condensed water accumulated on the partition plate 107 is provided on the rotating blade 105, so it is scattered by the rib 106 rotating together with the blade 105 and is formed on the inner surface of the main body 103. There is a problem that the sound of water droplets that collide is high, and it gives an uncomfortable feeling to the bather, and it is required to eliminate the noise of the water droplet and prevent the bather from feeling uncomfortable.
[0007]
In addition, there is a problem that water droplets are scattered in the exhaust port 102 to which a duct (not shown) is connected, and the water droplets leak from the end of the duct to the ceiling of the bathroom, so that the water droplets do not splash into the exhaust port. Is required to do.
[0008]
This invention solves such a conventional subject, and it aims at providing the ventilation dryer for bathrooms which can collect | recover condensed water without scattering and can prevent the dripping in a bathroom.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the bathroom ventilating dryer of the present invention has a box-like body having an opening on the lower surface and an exhaust port on the side portion, and a centrifugal force provided inside the body. Circulation fan, ventilation fan, heat exchanger, and ventilation fan are driven by a motor whose axis is vertical, and a suction port is provided on the lower surface. A fan casing and an annular rib provided on the inside of the fan casing so as to protrude toward the ventilation fan, and the rib surrounds the outside of the lower end of the ventilation fan at the suction port side outer position. In this way, a water reservoir is formed between the rib and the fan casing for receiving and collecting condensed water .
[0010]
ADVANTAGE OF THE INVENTION According to this invention, the ventilation dryer for bathrooms which can collect | recover without splashing dew condensation water and can prevent dripping is obtained.
[0011]
In addition, another means is provided with a drain hole provided in the lower surface of the water reservoir, and a front panel provided so as to cover the lower opening of the main body formed with a concave portion so as to receive water droplets from the drain hole. It is.
[0012]
And according to this invention, the ventilation dryer for bathrooms which can prevent dripping of condensed water even if it performs ventilation operation during bathing for a long time is obtained.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
The present invention provides a main body that is attached to a bathroom ceiling surface in a box shape having an opening on the lower surface and an exhaust port on a side portion, and a circulation fan and a ventilation fan including a centrifugal fan provided inside the main body, A heat exchanger and the ventilation fan are provided so as to be driven by a motor whose axial center is in a vertical direction, a fan casing having a shape surrounding the outside and having a suction port on the lower surface, and the fan casing inside the fan casing An annular rib projecting on the ventilation fan side, and the rib is formed so as to surround the outside of the lower end portion of the ventilation fan at the suction port side outer position, and between the rib and the fan casing A water reservoir is formed, and moisture containing moisture in the bathroom is sucked into the ventilation fan, and condensed water generated on the inner surface of the casing descends, and the water reservoir formed between the rib and the casing. Has the effect of condensed water can be prevented that the reservoir water droplets dripping.
[0014]
Also, a drain hole provided on the lower surface of the fan casing outside the rib, and a front panel provided so as to cover the lower opening of the main body formed with a concave portion so as to receive water droplets from the drain hole are provided. The dripping water from the fan casing is accumulated in a large amount by the dish-shaped part of the front panel, and even if the ventilation operation during bathing is performed for a long time, it has the effect of preventing the water droplets from dripping into the bathroom. .
Embodiments of the present invention will be described below with reference to the drawings.
