Description

[Detailed description of the invention] [Industrial field of application] This invention relates to an aerator that is attached to an outdoor wall and is configured to take in outside air through natural ventilation. Moreover, the present invention relates to a ventilator that can efficiently prevent rain, snow, etc. from blowing in.

[Prior Art] Conventionally, this type of ventilator has an opening at both the inner and outer ends, the inner side of which is formed into an insertion cylinder section that is inserted laterally into a hole in the outdoor wall, and the outer side of which is formed into an eaves section. The hood part is formed by closing the outer part of the cylindrical part inserted into the inside with the eave part at a predetermined interval, and the inner end surface of the cylindrical part is formed into a hood part. A closing part is provided to close the space between the part and the eaves part,
Additionally, there is known a device in which an air intake port is provided at the lower part of the cylindrical portion.

[Problems to be Solved by the Invention] The above-mentioned conventional type ventilator is formed such that an air intake port is provided at the lower part of the cylindrical portion to prevent rainwater and the like from entering from the upper part or the sides.

However, in the vicinity of high-rise buildings, the wind often blows upward from below. In such cases, wind carrying rainwater may directly enter the room through the air intake, and the rainwater may flow into the room along with the intruding wind.

Therefore, a technical problem arises that must be solved in order to prevent rainwater from flowing into the room even if the wind is from below, and the purpose of this invention is to solve this problem. do.

[Means for Solving the Problems] This invention was proposed to achieve the above object, and is an insertion method in which both the inner and outer ends are opened and the inner part is inserted horizontally into a hole in the outdoor wall. It has a hollow cylindrical ventilation pipe formed into a cylindrical part and whose outer part is formed as an eave part, and the outer part of the cylindrical part into which the eave part is inserted with a predetermined interval is closed to form a hood part. In the ventilator, which is formed into a cylindrical part and has a closing part that closes off between the cylindrical part and the eaves part on the inner end surface of the cylindrical part, a large number of horizontally elongated ventilation holes are provided around the entire circumference of the cylindrical part. It is an object of the present invention to provide an aerator, characterized in that the vent holes are arranged in parallel, and the vent holes are arranged such that the outer portion thereof is located outward from the outer periphery of the outer end of the eaves portion. be.

A large number of ventilation holes are opened in parallel around the entire circumference of the cylindrical part, and the rear part of the ventilation holes is arranged so as to open near the outer periphery of the outer end of the eave part. Even if wind blows from the tube and enters from the lower ventilation hole, the intruding wind is exhausted to the outside from the upper ventilation hole that faces along the circumference of the eaves inserted inside the tube. , and some of the intruding wind is alleviated inside the hood,
Ventilation flows into the room through the ventilation cylinder. At this time, the rainwater that enters through the lower ventilation hole due to the wind blowing up from below is scattered outside at the same time as the wind power dissipates along the outer circumferential surface of the eaves part, and does not enter the room.

In addition, wind and rain that enters from the side or from above are also discharged to the outside from the ventilation holes on the opposite side along the circumferential surface of the eaves. Along with the wind that escapes, it does not scatter outside and enter the room.
Furthermore, sufficient ventilation into the room is maintained as described above.

[Example] An example of the present invention will be described below with reference to the attached drawings. For convenience of explanation, conventionally known technical matters will also be explained at the same time.

An insertion tube that is made of a thin plate made of Sunterres steel or aluminum and has a hollow, substantially cylindrical tube portion 1 with both left and right ends open, and a flange-like closing portion 2 provided at one end of the tube portion 1. A hollow, substantially cylindrical eave portion 4 made of the same material as the insertion tube portion 3 and open at both left and right ends is attached to the tube portion 1 on the side of the closing portion 2 of the insertion tube portion 3. It is fixedly connected in a communicating manner to form the ventilation cylinder 5.

A hood body made of the same material as the ventilation cylinder 5, formed into a cylindrical part 7 whose outer part is closed with a hood part 6, and a flange part 8 provided around the open inner part of the cylindrical part 7. 9 is formed by, for example, drawing, and the cylindrical portion 7 is provided with oblong ventilation holes 10, 1 over its entire circumference.
0..., and fix the closing part 2 to the flange part 8 so that the ventilation pipe 5 is exposed inside the cylindrical part 7 of the hood body 9 so that the eaves part 4 is exposed, and the ventilation holes 10,
The outer portions of 10... are arranged so as to be located outward from the outer periphery of the outer end of the eaves section 4, and the outside air flowing into the hood body 9 from the ventilation holes 10, 10... 4 is formed into an aerator that flows into the ventilation cylinder 5 from the outside opening. Then, the ventilation tube 5 is inserted into a substantially inner cylindrical hole 12 that is provided by penetrating the outdoor wall 11 of the room 1 laterally inside and outside, and the ventilation tube 5 is inserted in an airtight manner through the ring-shaped packing 3. To securely fix the ventilator to the outdoor wall 11, which fits the cylinder 5 into the vent hole 12 and is elastically fitted by the fitting springs 14, 14, etc. fixed to the outer periphery of the vent tube 5. The flange 8 is held down using a caulking material 15, such as mortar or adhesive.

[Effects of the invention] The ventilator according to this invention is constructed as described above, and the ventilation pipe 5 that communicates the inside of the room 1 and the hood body 9 is connected to the outer periphery of the outer end of the eaves portion 4. Since a plurality of ventilation holes 10, 10, etc. arranged in the circumferential direction of the cylindrical portion 7 of the hood body 9 can be seen in the vicinity, the cylindrical portion 7 of the hood body 9 and the eaves portion 4 are viewed from approximately the lateral direction. Even when wind and rain blows, the wind and rain escape to the outside through the opposing ventilation holes 10, 10, . . . along the circumferential surface of the internal ventilation pipe 5. Then, the wind and rain that enters from the outside of the ventilation holes 10, 10... are relaxed in the hood part 6, and the rainwater is discharged to the outside through the ventilation holes 10, 10... This allows the air to flow into the room and create ventilation.
