Description

[Detailed description of the invention] This invention relates to a bathroom ventilation system installed on the bathroom wall.
In particular, the present invention relates to a bathroom ventilation system that is improved so as to prevent water droplets flowing down from the outer frame from flowing down along the bathroom wall surface.

Recently, a ventilation fan is generally installed in the bathroom to ventilate the bathroom, but in this case, the steam in the bathroom becomes water droplets and adheres to the ventilation fan, and the water droplets flow from the bottom of the outer frame to the bathroom wall. As a result, there was a problem that the part of the wall surface where the water droplets flowed down became dirty.

The present invention was developed in view of the above circumstances, and its purpose is to provide a ventilation system for a bathroom that can reliably prevent water droplets flowing down from the outer frame from traveling along the bathroom wall, and there is no risk of staining the wall. There is something to do.

An embodiment in which the present invention is applied to a ventilation fan for forced ventilation in a bathroom will be described below with reference to the drawings.

Reference numeral 1 denotes a bathroom wall, on which a mounting opening 2 is formed;
A wooden frame 3 is attached to the inside.

Reference numeral 4 denotes a synthetic resin outer frame of a ventilation fan inserted into the installation opening 2, and a flange 6 in an abbreviated shape is extended from the periphery of the opening 5 on the indoor A side toward the outside G. At the same time, a plurality of ribs 7 serving as spacing members are integrally protruded from the back surface 6a of the flange 6, and the flange 6 is fixed to the wooden frame 3 via screws 8.

Further, a drain portion 6b is formed at the lower end of the flange portion 6 and projects downward from the rib 7.

In this attached state, the flange 6, particularly the draining part 6b, and the wall surface 1a of the wall 1 are separated by the ribs 7.

Further, a tapered cylindrical portion 4a that is sequentially narrowed toward the outdoor B direction is formed on the peripheral edge of the outdoor B side opening portion 9 of the outer frame 4, and a discharge port body 10 is formed at the tip of this tapered cylindrical portion 4a. There is.

The lower portion of the tapered cylindrical portion 4a is an inclined portion 4b that slopes downward from the outdoor B side toward the indoor A direction.

A shutter 11 is attached to the discharge port body 10 so as to be rotatable to open and close, and a stopper 12 is provided at a position closer to the indoor A side than the shutter 11.

Incidentally, reference numeral 13 denotes a motor attached to the inside of the outer frame 4 via a support 14, and a blade 15 is directly connected to a rotating shaft 13a of the motor.

A decorative frame 16 is removably attached to the flange 6 by appropriate means so as to surround it, and has a decorative frame draining portion 17 extending downward from its lower end.

Therefore, when the steam in the room A turns into water droplets and adheres to the inner surface of the outer frame 4, the water droplets flow down from the drainage part 6b of the flange 6, but according to this embodiment with the above structure, the flange Since the part 6, particularly the draining part 6b, is separated from the wall surface 1a by the rib 7, the water droplets do not flow down along the wall surface 1a, but fall directly onto the floor of the bathroom.

Therefore, there is no risk that the wall surface 1a will be soiled by water droplets flowing down from the lower end of the drain section 6b of the collar section 6.

Although there may be a concern that water droplets flowing down from the draining portion 6b of the flange portion 6 may be transmitted to the wall surface 1a via the rib 7, the draining portion 6b is formed only by the thick bone of the flange portion 6. Having a step located below the lower end eliminates such concerns.

Further, according to this embodiment, at the lower part of the outdoor B side opening of the outer frame 4, there is a sloped part 4b that slopes downward from the outdoor B side toward the indoor A direction.
As a result, water droplets attached to the outer frame 4 can be prevented from flowing out to the outdoor B side, and conversely, they can be actively guided to the indoor A side, thereby preventing the water droplets attached to the outer frame 4 from flowing out. Outdoor B
You can put it back into the bathroom without having to take it out.

In addition, especially according to this embodiment, as a result of the rib 7 separating the flange portion 6 from the wall surface 1a, a gap is formed between the decorative frame 16 and the wall surface 1a to the extent that a finger can be inserted into the decorative frame 1.
This is convenient for the installation and removal work of item 6.

Note that the water droplets adhering to the decorative frame 16 fall directly onto the floor of the bathroom from the decorative frame draining part 17, and there is no possibility that the wall surface 1a will be soiled by the water droplets flowing down from the decorative frame 16.

In the above embodiments, the present invention has been explained by applying it to a ventilation fan, but the present invention is not limited to the above embodiments. For example, the motor 13, the blades 15, etc. The present invention can be implemented with various modifications without departing from the gist, such as being applicable to a type of ventilation system that performs ventilation by natural ventilation without installing a blower.

As explained above, the present invention includes a flange extending downward at least at the lower edge of the indoor side opening edge of the outer frame, and a water cutter formed at the lower end of the flange, so that the flange is connected to the bathroom. By providing a spacing member on the outer frame to separate it from the wall surface and allowing water droplets to fall from the lower end of the drain of the collar without being transmitted to the wall surface, the water droplets flowing down from the outer frame will not touch the bathroom wall surface. Water droplets can be reliably prevented from leaking into the room, and there is no risk of staining the wall surface. Furthermore, since a sloping part is formed at least at the bottom of the outdoor side opening edge of the outer frame, which slopes downward from the outdoor side toward the indoor direction, water droplets can be prevented from entering the room. It is possible to provide a bathroom ventilation device that can reliably prevent water droplets from flowing outside and can also return water droplets indoors.
