Abstract

(57) [Summary] [Purpose] It is possible to prevent as much as possible the formation of traces of dirty water, such as dust and oil dissolved in rainwater, under the ventilator installation location on the exterior wall of the building. [Structure] The mounting ventilator according to the present invention is provided with a guide frame in which a forward protruding collar is formed on the outer periphery of a semicircular frame flange in the lower half of the outward flange formed at the front end of the opening of the cylindrical main body tube. It has a similar structure.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The attached ventilator of this invention is used for indoor ventilation of buildings.

0002

[Conventional technology]

A ventilator for indoor ventilation is used by fitting it into a mounting hole drilled in the wall of a building, but conventionally The cylindrical ventilator consists of a simple cylindrical main body.

0003

[Problem that the idea aims to solve]

With conventional aerators like this, dust and oil accumulated at the top of the main body tube and the outlet are removed by rain. Sometimes it dissolves in rainwater and flows down as dirty water, but this dirty water is transmitted along the exterior walls of buildings. As it flows down, the traces of the flow become black stains that remain on the exterior wall surface, ruining the beauty of the exterior wall surface. The view is lost in a short period of time.

0004 This invention reduces the amount of traces of dirty water left on the exterior walls of buildings, and extends the beauty of the exterior walls. We are now able to provide an attached ventilator that can be maintained for years.

[0005]

[Means to solve the problem]

The attached ventilator according to the present invention has an outward flange formed at the front end of the opening of the cylindrical body tube. The structure has a water receiving guide frame consisting of a collar protruding forward on the outer periphery of the lower half of the cage. It is a thing.

[0006]

[Effect]

The mounting ventilator of the present invention is installed by penetrating the wall of the building.

[0007] In this way, indoor air is exhausted from the main body cylinder to the outdoors.

[0008] In addition, dust and oil that accumulate on the outward flange of the main body cylinder and the guide frame may become contaminated with water during rainy weather. As a result, the dirty water from the outward flange flows down into the water receiving guide frame, and then flows inside the guide frame. It flows down together with dirty water, but the dirty water protrudes to the front of the guide frame. Since it falls from the edge of the collar, it rarely flows down the exterior wall of the building. do not have.

[0009]

【Example】

<Example 1> 1 to 4 show an example of an attached ventilator according to the present invention.

0010 In the figure, reference numeral 1 is a cylindrical main body tube, and an outward flange 2 is attached to the periphery of the front end of the opening. The lower half of the rear end opening 1b is closed by a half rear plate 3.

[0011] A louver plate 4 is attached to the front end opening of the main body cylinder 1 by means of rivets 5 to attach the outward flanges of the main body cylinder 1. At the same time, the louver plate 4 and the outward flange 2 of the main body cylinder An insect screen 6 is attached between the two.

0012 By forming a plurality of cut and raised louver pieces 7 on the top and bottom of the louver plate 4 that tilt forward. A large number of horizontally elongated slit-shaped louver ventilation holes 7a are provided at the top and bottom.

[0013] In addition, a guide frame 8 protruding forward is provided in the lower half of the outward flange of the main body cylinder. is provided.

[0014] This guide frame protrudes from the outer periphery of the semicircular frame flange portion 8a with a slightly enlarged diameter forward. The frame flange 8a is fixed with a rivet 5. It is attached to the outward flange of the body cylinder by fastening it to the outward flange 2 of the body cylinder. Ru.

[0015] In addition, the collar 8b is designed to prevent dirt water from exhaust or rain from falling without being transmitted along the outer wall surface. It has a slightly forward-inclining fold at the top of both left and right ends of the frame flange 8a. A bent water stop piece 9 is formed.

[0016] Note that the guide frame may be molded integrally with the outward flange of the main body cylinder.

[0017] The ventilator of this embodiment is fitted into a mounting hole 11 in a wall 10 of a building as shown in FIG. Install it, and apply caulk as appropriate between the outer periphery of the flange of the main body cylinder and the wall to seal it. file.

[0018] Dirty air containing oil smoke etc. from the room enters the main body cylinder 1 through the rear end opening 1b, The air is exhausted diagonally downward and forward from the louver ventilation hole 7a of the louver plate.

[0019] In addition, dust, oil, etc. may accumulate on the surface of the outward flange 2 and the inner surface of the guide frame 8 during use. When it rains, these become dirty water, but the color guides all the dirt. It will temporarily accumulate within the frame. However, since the guide frame protrudes forward from the outer wall surface, it may become dirty. It is unlikely that water will flow down the wall, and the location where the ventilator is installed on the exterior wall There are almost no traces of dirty water left underneath.

[0020] Further, the guide frame 8 has an outer periphery of a frame flange 8a that has a larger diameter than the outward flange of the main body cylinder. By forming the collar 8b on the outer periphery of the upper half of the outward flange, It can catch water flowing down the wall and let it fall from the bottom edge of the collar. can.

[0021] <Example 2> 5 to 7 show another example of the attached ventilator according to the present invention.

[0022] In this example, a hood 12 is provided on the front surface of the flange of the main body cylinder. The hood 12 has a hemispherical shell shape with an open bottom, and a flange. A guide frame 8 is provided in the lower half portion as in the embodiment.

[0023] The main body cylinder of this example has the same structure as the main body cylinder of Example 1. Therefore, each constituent part is simply given a reference numeral and a description thereof is omitted.

[0024] Since the installed ventilator in Example 2 is equipped with a hood, rain and wind will not flow back into the room. be prevented from doing so.

[0025] In addition, dirty water such as dust on the surface of the hood, dust on the inside, dust on the inside, oil, etc. dissolved in rainwater This also flows down to the guide frame 8, and is transmitted from the lower edge of the guide frame to the outer wall of the building. It falls without any problem, leaving almost no traces of dirt or water on the exterior wall surface.

[0026]

[Effect of the idea]

The mounting ventilator of the present invention is equipped with the guide frame mentioned above, so it can be mounted on the outside wall of the building. There are fewer traces of dirty water left under the ventilation ventilation installation point, and the appearance of the exterior wall is improved. You can maintain your vision for many years.
