Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ventilation port suitable for a room or kitchen in a house or the like.

[0002]

[Prior art]

 Conventionally, this kind of thing is as follows. When the outside temperature is -5 ° C, the room temperature is usually around 25 ° C, and cold air and water with 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]

[Problems to be solved by the device]

 The conventional techniques described above have the following problems. Oxygen deficiency may occur, and the gas fire may sometimes go out, and the dirty air from the gas stove will fill the room even if the range hood is moved. In the conventional ventilation port, there is no ventilation port with an air filter installed, and car dust, dust, pollen, etc. enter the room as it is, and air containing cold water enters 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 in the room.

The present application has been made in view of such problems of the conventional technology, 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 is a lateral pipe 1A that is inserted from the indoor side into a pipe 2A that is embedded between the outer wall of the wall surface 2 and the indoor wall, and the lateral pipe at the chamber inner end opening 1A1 of this lateral pipe. It is composed of a rear vertical plate 1B which is connected in a direction orthogonal to the longitudinal direction of the rear vertical plate, and a front vertical plate 1D which is stretched in parallel with the rear vertical plate through a frame portion 1C on the front surface of the rear vertical plate. 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 front upward U shape, and at the rear end of the frame portion 1C, a horizontal pipe chamber. This is a ventilation port to which a filter unit 1E is detachably attached so as to cover the inner end opening 1A1.

In this case, the filter section 1E includes a vertical plate 1E1 which is raised and lowered while being guided by a vertical groove 1C21 formed in the left and right side plates 1C2 of the frame section 1C, a circular opening 1E2 formed in the vertical plate, and this circular plate. It is composed of a sponge-like filter 1E3 stretched over the mouth part. 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. be able to. Further, the sideways pipe 1A can be provided with a fitting 1F for mounting to the pipe 2A embedded between the outer wall of the wall surface 2 and the indoor wall.

[0007]

【Example】

 Examples will be described with reference to the drawings. 1 is the ventilation opening of the present invention. 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 port 1 of the present invention is mounted. 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 configuration of the ventilation port 1 is as follows. A horizontal pipe 1A is inserted from the indoor side into a pipe 2A embedded between an outer wall and an indoor wall, and an indoor end opening 1A1 of the horizontal pipe has a direction orthogonal to the longitudinal direction of the horizontal pipe. It is composed of a rear vertical plate 1B which is continuously connected and a front vertical plate 1D which is stretched in parallel with the rear vertical plate through a frame portion 1C on the front surface of the rear vertical plate.

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

Therefore, the filter portion 1E is provided with a vertical plate 1E1 which moves up and down while being guided by a vertical groove 1C21 formed in the left and right side plates 1C2 of the frame portion 1C, a circular opening 1E2 opened in the vertical plate, and It is composed of a sponge-like filter 1E3 stretched around the circular opening. In this case, as the filter 1E3, the thicker filter 1E31 is used for the winter season, and the thinner 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. 1F1 and 1F2 are outer and inner circular holes opened 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.

Reference numeral 1F3 denotes a spring, which is made of a spring plate having a width that allows loose fitting in the circular holes 1F1 and 1F2, and has an outer spring plate 1F31 that bends outward and a spring plate of the outer spring plate. It is composed of an inner spring plate 1F32 which is located inward and curved outward, and both are connected at the upper end. When the spring 1F3 is attached to the sideways 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 arranged in the inner circular hole 1F2. Insert and lock. As a result, the outer spring plates 1F3 are attached to the upper and lower parts of the lateral pipe 1A in an enormous outward condition.

The effects of this mounting bracket 1F are as follows. 1. Construction can be completed in a short time by simply attaching it to the pipe 2A (for example, a diameter of 100 m / m) embedded between the outer wall where the ventilation port 1 is attached to the wall surface 2 and the indoor wall. 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 effect.

[0015]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. 1. During the winter, the cold air that is sucked in enters through the lateral pipe 1A, is reliably dust-removed by the filter unit 1E, reaches the frame 1C, and is discharged upward, that is, toward the ceiling from the top opening 1C3 of this frame. It In the normal room, warm air in the room stays in the ceiling, but cold air mixes with this air, and the room temperature can be kept at a reasonable level.

2. In the summer, installing a filter removes dirty air from the outside, and the filter slows down the wind speed, so it also removes moisture and also prevents noise and privacy. In addition, the air inside the room, which had been under a negative pressure when the ventilation fan was rotated, flowed faster, which was uncomfortable, but with this model, the air that was taken in once went to the ceiling. Can be resolved.
