Description

[Detailed description of the device]

[0001]

[Industrial field of application] The present invention relates to a ventilation port suitable for a room or kitchen in a house or the like.

[0002]

2. Description of the Related Art Heretofore, in this type, the following has been done. When the outside temperature is −5 ° C., the room temperature is usually around 25 ° C., and cold air and water having a difference of 30 ° C. enter the room directly. For this reason, in winter, the shutter was closed to completely block the entry of fresh air.

[0003]

The problems described in the prior art have the following problems. Oxygen deficiency occurs, and sometimes the gas fire may go out, and the dirty air from the gas stove will fill the room even if the range hood is moved. Also, in the conventional ventilation port, there is no ventilation port with an air filter attached,
Car powder, sand dust, pollen, etc. entered the room as they were, and cold air containing air entered the room directly. Then, the noise of the room leaked to the outside as it was, and there was a problem of privacy, and the noise came into the room.

The present application has been made in view of the above problems of the prior art, and an object of the present application is to provide a device capable of solving the above problems.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention is as follows. That is, the pipe of the present application has a lateral pipe 1A which is inserted from the indoor side into a pipe 2A embedded between the outer wall of the wall surface 2 and the indoor wall, and the lateral pipe at the indoor end opening 1A1 of the lateral pipe. And a front vertical plate 1D stretched in parallel with the rear vertical plate via a frame portion 1C on the front surface of the rear vertical plate. The frame portion 1C is configured by connecting left and right side plates 1C2 to the both ends of a bottom plate 1C1 having a band plate of a predetermined size in a front upward U shape, and at the rear end of the frame portion 1C, a lateral pipe is opened on the indoor side end side. It is a ventilation port to which a filter unit 1E is detachably attached while covering the unit 1A1.

In this case, the filter portion 1E is the frame portion 1C.
A vertical plate 1E1 that is moved up and down while being guided by a vertical groove 1C21 formed in the left and right side plates 1C2, a circular opening 1E2 opened in this vertical plate, and a sponge-shaped filter 1E3 stretched over the circular opening. As the filter 1E3, the thick filter 1E31 for the winter season may be used, and the thin filter 1E32 for the summer season may be used. Further, the sideways pipe 1A can be provided with a fitting 1F for the pipe 2A embedded between the outer wall of the wall surface 2 and the indoor wall.

[0007]

EXAMPLES Examples will be described with reference to the drawings. 1
Is the ventilation opening of this plan. Reference numeral 2 is a known wall surface, and 2A is a pipe embedded between the outer wall and the indoor wall where the ventilation opening 1 of the present invention is mounted on the wall surface. That is, the ventilation opening 1 of the present invention is attached to the indoor side of the pipe 2A embedded between the outer wall and the indoor wall, and although not shown, it is embedded between the outer wall and the indoor wall. A known hood is attached to the outside of the pipe 2A.

Therefore, the structure of the ventilation port 1 is as follows. Pipe 2 embedded between the outer wall and the inner wall
A sideways pipe 1A penetrating from A to the inside of the room, a rear vertical plate 1B continuously connected to the indoor end opening 1A1 of the sideways pipe in a direction orthogonal to the longitudinal direction of the sideways pipe, and this rear vertical plate. And a front vertical plate 1D stretched in parallel with the rear vertical plate via a frame portion 1C on the front surface of the.

In view of this, the frame portion 1C is constructed by connecting the left and right side plates 1C2 to the both ends of a bottom plate 1C1 having a band plate of a predetermined size in a U-shape facing upward in the front. 1C3 is an upper surface opening formed on the upper surface of the frame portion 1C. Further, the frame portion 1C
A filter portion 1E is detachably attached to the rear end of the lateral pipe so as to cover the indoor end opening 1A1 of the sideways pipe.

Therefore, the filter portion 1E is the frame portion 1
From a vertical plate 1E1 that is moved up and down while being guided by a vertical groove 1C21 engraved on the left and right side plates 1C2 of C, a circular opening 1E2 opened in this vertical plate, and a sponge-shaped filter 1E3 stretched over this circular opening. It is configured. in this case,
As the filter 1E3, a thick filter 1E31 is used for the winter season, and a thin filter 1E32 is used for the summer season. It should be noted that the design of the front vertical plate 1D naturally changes to a round shape, a square shape, or any other design that fits inside the room.

Reference numeral 1F is a mounting member, the structure of which is as follows. Reference numerals 1F1 and 1F2 denote outer and inner circular holes formed at positions facing each other in the upper and lower portions of the lateral pipe 1A. The diameter of these circular holes 1F1 and 1F2 is about 5 mm.

1F3 is a spring, and circular holes 1F1 and 1F
Outer spring plate 1F31 that outwardly bends using a spring plate configured to have a width that allows loose fitting in 2
And an inwardly curved inner spring plate 1F32 positioned inside the outer spring plate, the two being connected at the upper end. And this spring 1F
3 is attached to the lateral pipe 1A, the upper end portion of the spring 1F3 is inserted and locked in the outer circular hole 1F1, and the lower end of the inner spring plate 1F32 is attached to the inner circular hole 1F.
Insert into 2 and lock. As a result, the outer spring plate 1F3
Will be attached to the upper and lower parts of the lateral pipe 1A in an enormous state outward.

The effects of this mounting member 1F are as follows. 1. The pipe 2A (for example, a diameter of 100 m /
It can be installed in a short time only by attaching it to m). 2. Even if the wall surface 2 has a different thickness, it can be easily dealt with.

The operation will be described together with the effects.

[0015]

Since the present invention is constructed as described above, it has the following effects. 1. In the winter period, the sucked cold air enters through the lateral pipe 1A, is reliably dust-removed by the filter portion 1E, reaches the frame portion 1C, and is discharged upward from the top surface opening portion 1C3 of the frame portion, that is, toward the ceiling. In the normal room, warm air in the room is retained in the ceiling portion of the room, but cold air is mixed with this air, and the room temperature can be kept at a suitable level. In this case, the left and right side plates 1 are attached to both ends of the bottom plate 1C1.
Is C2 constructed by continuously arranging it in a U shape facing upward on the front?
The filter part 1E can be inserted and removed from above.
It Place furniture such as a closet next to the ventilation opening in the room.
Even if they are placed in contact with each other, in the case of the present invention, the filter
Since the first portion 1E is configured to be inserted and removed from above,
Replacement of the filter section 1E is disturbed by these furniture and the like.
Can be done easily without. Also, the filter section
1E is provided, so snow that comes in due to snowstorm
Can be reliably prevented.

2. In the summer, installing a filter removes dirty air from outside, and the filter slows down the wind speed, removing water and also preventing noise and privacy. In addition, the air inside the room, which had a negative pressure when the ventilation fan was rotated, flowed faster, which was uncomfortable, but in the case of this proposal, the air taken in once goes to the ceiling. Can be resolved.
