Description

Natural ventilation appratus in which the ventilation volume increases}

The present invention relates to a natural ventilation device, and more particularly, to a natural ventilation device that increases the amount of ventilation that can be introduced into an indoor space after filtering a large amount of outside air.

In general, a building is provided with a window, and the indoor air is ventilated using the window.

Polluted indoor air causes many diseases to the human body. In particular, various dust and microorganisms in the polluted air cause respiratory diseases and various allergies, and various pollutants (formaldehyde, volatile organic matter) emitted from indoor building materials. , asbestos powder) cause diseases such as headache, cough, and itching.

Therefore, it is desirable to prevent the accumulation of various pollutants in the room by frequently ventilating the air by ventilating the room and the outside.

However, as described above, since ventilation using a window is usually performed with the window open, a strong external wind directly flows into the room through an open window, or rainwater or dust flows into the room together with the wind. There was a problem.

In addition, as pollutants such as fine dust or yellow sand, which have become serious problems in recent years, are introduced into the indoor space as they are, there is a great risk that the ventilation itself may not function as well as damage to the human body.

In order to solve this problem, a ventilation device equipped with a filter is recently installed on a window or wall, etc., and a natural ventilation device is used that filters outside air through the ventilation device without opening the window and then supplies it to the room.

However, the conventional natural ventilation device has a problem in that the amount of ventilation is small because external air is introduced into the room after passing through the filter.

Registered Patent: 10-1769530 (Application No.: 10-2015-0159516, Title of Invention: Natural ventilation device for window installation)

The present invention has been devised to solve the problems of the prior art, and the amount of ventilation that can be introduced into the indoor space after purifying a large amount of outside air per unit time by changing the installation shape of the filter that filters outside air An object of the present invention is to provide an increased natural ventilation system.

In addition, when the flap that opens and closes the air passage connecting the indoor space and the outdoor space rotates, both the upper and lower air passages of the flap are opened to provide a natural ventilation device that increases the amount of ventilation that can further increase the amount of ventilation. There is a purpose.

A natural ventilation device for increasing the amount of ventilation according to the present invention for solving the above problems includes: a main body having an air flow path formed between an upper body and a lower body spaced apart by a predetermined distance in the vertical direction; end caps installed on both ends of the body; a flap rotatably installed on the end cap to open and close the air passage; and a filter cover installed on the front surface of the main body, having a plurality of ventilation holes, and having a fine dust filter corrugated in a zigzag shape installed at the rear of the ventilation hole.

Here, when the air flow path is opened by rotation of the flap, upper and lower portions of the air flow path are opened based on the flap.

In addition, a wheel rotating on the end cap is installed at both ends of the flap, and airtight ribs that are in close contact with the front and rear surfaces of both ends of the flap protrude from the wheel.

In addition, an indicator for rotating the flap by sliding in the vertical direction to rotate the wheel is installed on the end cap, and a see-through hole for exposing the indicator is formed in the filter cover.

In addition, the indicator includes a cover panel that is painted in different colors in the vertical direction and exposed through the see-through hole; and a sliding part connected to the rear surface of the cover panel and having a shaft groove formed on one side into which a wheel shaft provided on the wheel is inserted.

In addition, a handle groove to which a handle is connected is formed on the other side of the sliding unit, and the sliding unit and the indicator panel slide up and down according to the movement of the handle.

In addition, the rear surface of the sliding part is provided with a rack that moves up and down together with the sliding part, an electric motor is provided inside the end cap, and a pinion toothed to the rack is installed on the motor shaft of the electric motor.

In addition, an upper insertion groove is formed in an upper portion of the rear surface of the flap, and a lower protrusion to be inserted into the upper insertion groove is formed in a lower portion of the upper body; A lower insertion groove is formed in a lower front portion of the flap, and an upper protrusion inserted into the lower insertion groove is formed in an upper portion of the lower body.

In addition, the filter cover is provided with a square frame enclosing and sealing the edge of the fine dust filter on the rear side.

In addition, the material of the fine dust filter is selected from mesh, nanofiber, and nonwoven fabric.

In the natural ventilation device for increasing the ventilation volume of the present invention configured as described above, since the fine dust filter is mounted in a zigzag corrugated form, more micropores of the filter exist in a unit section, thereby providing a larger amount of air per unit time. There is an advantage in that the amount of ventilation can be increased by filtering the outside air and then supplying it to the room.

In addition, since both the upper and lower air passages of the flap are opened by the rotation of the flap, a larger amount of external air can be filtered and supplied to the room per unit time compared to the conventional natural ventilation device in which only one side is opened. There is this.

In addition, since both ends of the flap are surrounded by the airtight ribs, there is an advantage in that the possibility that outside air flows into the room through both ends of the flap without going through filtering is reduced.

In addition, there is an advantage in that it can be easily determined whether the flap has opened or closed the air flow path through the color painted on the indicator panel of the indicator exposed to the outside through the see-through hole.

In addition, since the rectangular frame seals the edge of the fine dust filter, all the outside air passes through the fine dust filter and then flows into the room, thereby improving indoor air quality.

The main body 10 is composed of an upper body 11 and a lower body 12 spaced apart from the upper body 11 in the vertical direction.

The upper body 11 forms the upper outer shape of the main body 10, and the lower protrusion 11a is elongated in the left and right directions on the lower side.

The lower body 12 is installed to be spaced apart from the lower side of the upper body 11 by a predetermined distance to form an air flow path 10a between the lower body 11 and the upper body 11 . The lower body 12 has an upper protrusion 12a on the upper side thereof that is long in the left and right directions.

The end cap 20 connects the upper body 11 and the lower body 12 that are separated from each other to fix the upper body 11 and the lower body 12, thereby fixing the upper body 11 and the lower body 12. ) to maintain the air flow path (10a) formed between them. The end cap 20 includes a first cap 21 and a second cap 22 coupled to the first cap 21 .

The first cap 21 is coupled to both ends of the main body 10 to integrate the upper body 11, the lower body 12, and the first cap 21. A wheel insert groove 21a is formed in the first cap 21 to be mounted and rotates a wheel 40 to be described later, and a wheel shaft 41 provided in the wheel 40 passes through the wheel insert groove 21a. A guide hole 21b of a curved shape that moves is formed. In addition, a cover 21c is detachably installed on the front surface of the first cap 21 .

The second cap 22 is assembled to the first cap 21 and is bound to the upper body 11 and the lower body 12 to form a constant accommodation space between the second cap 21 and the first cap 21 .

The flap 30 is installed between the upper body 11 and the lower body 12 to open and close the air passage 10a. That is, when ventilation is not performed, the entire air passage 10a is blocked by the flap 30 , and when the flap 30 is rotated for ventilation, the air passage 10a is opened. When the air flow path 10a is opened by the rotation of the flap 30 in this way, upper and lower portions of the air flow path 10a are opened with respect to the flap 30 .

That is, when the flap 30 rotates, not only one air flow path such as the lower or upper side of the flap 30 is opened, but both the upper and lower air flow paths of the flap 30 are opened. When both the upper and lower air passages are opened, there is an effect of increasing the ventilation amount than when either the upper or lower air passages are opened.

And, since the shape of the flap 30 is made of a soft curved surface shape with the front and rear surfaces in contact with the upper and lower ends, when outdoor air enters the room or when the indoor air goes out, the air flows to a specific place It is possible to have a smooth air flow by preventing the formation of a vortex or the generation of a gust by colliding.

In addition, the flap 30 has an upper insertion groove 31 formed on the upper rear portion, and a lower insertion groove 32 formed on the front lower portion.

The lower protrusion 11a of the upper body 11 is inserted into the upper insertion groove 31 , and the upper protrusion 12a of the lower body 12 is inserted into the lower insertion groove 32 . Accordingly, when the flap 30 closes the air flow path 10a, the air flows through the upper end of the flap 30 and the lower end of the upper body 11 and the lower end of the flap 30 and the upper end of the lower body 12. can be prevented from doing

On the other hand, the flap 30 rotates in front of the air flow path 10a between the upper body 11 and the lower body 12, but the rotation of the flap 30 applies the force to both ends of the flap 30. It is provided through the installed wheel (40).

In more detail, the wheel 40 rotates on the end cap 20, and is inserted into the wheel insertion groove 21a formed in the first cap 21, and at the same time, the wheel shaft ( 41) is inserted into the guide hole 21b formed in the wheel insertion groove 21a. In this state, when the wheel 40 rotates within the wheel insertion groove 21a of the first cap 21, the flap 30 rotates and the wheel shaft 41 moves along the guide hole 21b. do.

And, an airtight rib 42 is formed to protrude from one side of the wheel 40 .

Between the airtight ribs 42, both end portions of the flap 30 are inserted, so that the airtight ribs 42 are in close contact with the front and rear surfaces of both ends of the flap 30. Therefore, the airtightness between the both end portions of the flap 30 and the wheel 40 is increased to prevent air from flowing therebetween.

In addition, a plurality of fitting rods 43 are formed to protrude up and down between the airtight ribs 42 on the wheel 40 , and a plurality of fitting holes 33 are vertically formed between the front and rear surfaces of the flap 30 . is formed with As the fitting rod 43 of the wheel 40 is fitted in the fitting hole 33 , the wheel 40 and the flap 30 are firmly fixed.

Meanwhile, the end cap 20 is provided with an indicator 50 that informs whether the air flow path 10a is opened or closed by the flap 30 and rotates the wheel 40 and the flap 30 .

The indicator 50 is exposed to the outside through the see-through hole 63 of the filter cover 60 to be described later to inform whether the air passage 10a is open or closed, and slides in the vertical direction from the end cap 20 to the wheel 40 ) to rotate the flap 30 . That is, when the indicator 50 moves up and down by an external force, the wheel 40 rotates, and as a result, the flap 30 rotates.

In more detail, the indicator 50 includes a cover panel 51 and a sliding part 52 integrally formed on the rear surface of the cover panel 51 .

The cover panel 51 is painted in different colors in the vertical direction and exposed through the see-through hole 63 of the filter cover 60 . It can be checked whether the air flow path 10a is opened or closed through this color. As described above, different colors can be painted to expose different colors to the outside when the air flow path 10a is opened and closed. , a specific color may be painted on the cover panel 51 in a gradation method to indicate the degree of opening of the air flow path 10a.

The sliding part 52 is integrally connected to the rear surface of the cover panel 51, and a shaft groove 52a is formed on one side thereof.

The wheel shaft 41 provided in the wheel 40 is inserted into the shaft groove 52a. The wheel shaft 41 is inserted into the shaft groove 52a after passing through the guide hole 21b formed in the first cap 21 . At this time, the shaft groove (52a) is not a perfect circle, but has a shape close to an elliptical shape longer in the horizontal direction than in the vertical direction. This is because the guide hole 21b for guiding the wheel shaft 41 is formed long in the vertical direction and takes a slightly convex curved shape toward the filter cover 60 side.

A handle groove 52b is formed on the other side of the sliding part 52, and a handle 52c is connected to the handle groove 52b.

In the present invention, the rotational driving of the flap 30 may be performed manually or automatically. In the case of manual operation, a handle groove 52b is formed on the other side of the sliding unit 52 as described above, and the handle The handle 52c is connected to the groove 52b. Accordingly, the sliding part 52 slides up and down according to the movement of the handle 52c, and also slides up and down with the cover panel 51 .

When the sliding part 52 slides up and down in this way, the wheel shaft 41 moves within the curved guide hole 21b, and as a result, the wheel 40 rotates within the wheel insertion groove 21a, and eventually the flap (30) is rotated.

On the other hand, when automatically driving the flap 30, instead of connecting the handle 52c to the handle groove 52b, the rack that moves up and down together with the sliding unit 52 on the rear side of the sliding unit 52 A pinion (54a) is provided on the motor shaft of the electric motor (54) installed inside the end cap (20), and then the pinion (54a) is toothed with the rack (53).

Accordingly, when the electric motor 54 operates and the motor shaft rotates, the pinion 54a rotates, and the rack 53 toothed to the pinion 54a slides in the vertical direction. As a result, the sliding part 52 and the cover panel 51 slide up and down together.

In other words, as described above, the cover 21c is installed on the first cap 21 , and the electric motor 54 is installed inside the end cap 20 after the cover 21c is opened.

The filter cover 60 is installed at the front of the main body 10, a plurality of ventilation holes 61 are formed therein, and a square frame 62 is provided on the rear side.

External air introduced through the ventilation hole 61 passes through a fine dust filter 70 to be described later.

The rectangular frame 62 is formed in a quadrangular shape on the rear surface of the filter cover 60, and all of the plurality of ventilation holes 61 are located inside the rectangular frame 62. A fine dust filter 70 for filtering fine dust is installed in this square frame 62 .

The fine dust filter 70 is not formed in a flat shape, but is formed in a pleated shape in a zigzag shape. When the fine dust filter 70 is configured in such a shape with a plurality of pleats, there is an effect that the ventilation amount can be increased.

That is, if the fine dust filter 70 having many wrinkles is arranged in a certain space, the fine pores of the fine dust filter are larger than when the filter is flat, so that the ventilation amount is increased.

And, the fine dust filter 70 is installed inside the square frame 62, and since the edge of the fine dust filter 70 is fixed to the inner surface of the square frame 62 and sealed while surrounded by the square frame 62, the fine dust filter 70 is closed. The dust filter 70 covers the entire ventilation hole 61 , so that all of the external air flowing into the room through the natural ventilation device of the present invention passes through the fine dust filter 70 .

Here, the material of the fine dust filter 70 is selected from those including mesh, nanofiber, and nonwoven fabric.

For example, it may be manufactured by spraying nanofiber particles on the upper surface of the mesh to form a nanofiber layer, then covering the mesh again on the nanofiber layer and then wrinkling it in a zigzag shape. Of course, it is natural that the material or manufacturing method of the fine dust filter 70 is not limited to the above.

On the other hand, see-through holes 63 are formed on both sides of the filter cover 60 .

As described above, the cover panel 51 of the indicator 50 is exposed to the outside through the see-through hole 63, and whether the air flow path 10a is opened or closed or the degree of opening and closing depending on the color of the exposed cover panel 51 can be known
