Abstract

PROBLEM TO BE SOLVED: To prevent a bather from feeling discomfort by providing a water catch pan between a cover that covers the circumference of an impeller and a panel that covers the front of the impeller. SOLUTION: When a ventilator is put into operation, a motor 3 and an impeller 1 mounted on a shaft of the motor 3 begin to rotate to discharge wet air in a bathroom outside the bathroom. During operation, dew is formed on the impeller 1 and main body 9. Especially, dew formation on the impeller 1 is continuously splashed toward a cover 2 by centrifugal force, and dew water 10 flows from a bell-shaped part of the cover 2 into a water catch pan 5. On the other hand, dew water 8 attached on the min body 9 flows from a recessed part 6 of the cover 2 into the water catch pan 5 via a projected part 7 of a flange 11. Thus, dew water 10 produced in the ventilator can be gathered in the water catch pan 5, preventing the dew water in a bathroom from dripping down.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation fan used in bathrooms for general household use, and more particularly to a structure of the ventilation fan designed to prevent the dew condensation water from dropping into the bathroom.

[0002]

2. Description of the Related Art A conventional ventilation fan is as shown in FIGS.
The condensed water adhering to the main body was transmitted to the front panel portion from the cover and the main body, flowed out from the gap between the panel and the main body, and dripped into the bathroom from the inner wall surface.

[0003]

However, the conventional ventilation fan has a drawback in that the dew condensation water dripping from the inner wall surface into the bathroom drips on the human body of the bather who is taking a bath, which causes discomfort.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and to provide a ventilating fan for preventing condensation water from dripping into the bathroom.

[0005]

To solve the above-mentioned problems, the present invention is characterized in that a main body for holding an electric motor, a blade pivotally supported by the electric motor and driven by the electric motor, A ventilation fan having a cover that covers the periphery of the blade and a panel that covers the front surface of the blade, wherein the ventilation fan has a water reservoir provided between the panel and the cover.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a sectional view of a ventilation fan according to one embodiment of the present invention, and FIG. 4 is a front view of the ventilation fan according to one embodiment of the present invention.

In FIGS. 1 and 4, the electric motor 3 is screwed to the main body 9, and the blades 1 are mounted on the shaft portion of the electric motor 3.
The cover 2 covering the periphery of the blade 1 has a concave portion on the lower surface and is fixed to the main body 9 with a screw. The flange portion 11 of the main body 9 is provided with a draining convex portion 7, and the water reservoir portion 5 is attached and fixed to the flange portion 11 below the convex portion 7. The front panel 4 is attached and fixed to the flange portion of the main body 9 by elasticity.

In the above structure, when the ventilating fan is operated, the electric motor 3 starts to operate, and the blades 1 mounted on the shaft of the electric motor 3 also start rotating at the same time, so that the moist air in the bathroom is discharged to the outside.

At this time, dew condensation occurs on the blade 1 and the main body 9. In particular, the dew condensation adhered to the blades 1 is continuously scattered toward the cover 2 by centrifugal force, and the dew condensation water 10 flows into the water reservoir 5 from the bell-shaped portion of the cover 2.

On the other hand, the condensed water 8 attached to the main body flows from the concave portion 6 of the cover 2 through the convex portion 7 of the flange portion 11 into the water reservoir portion 5. In this way, the dew condensation water generated in the ventilation fan can be collected in the water reservoir 5.

[0012]

According to the present invention, since the water reservoir is provided between the panel and the cover, the dew condensation water does not flow out of the main body, which gives a bather an uncomfortable feeling while taking a bath. Can be prevented.
