Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to an air supply/exhaust louver suitable for installation in buildings such as food and chemical factories, in particular.

``Conventional technology'' Conventionally, supply and exhaust louvers installed on building walls for ventilation, ventilation, etc. are of the type that directly supply and exhaust indoors and outdoors, and those that supply and exhaust air through ducts. There are various types and models, but those equipped with dustproof filters, insect screens, shutters, etc. are usually used especially for ventilation and air conditioning equipment in food and chemical factories. The filter is installed in a separate filter box.

"Problems to be Solved by the Invention" In the air supply and exhaust louvers equipped with the above-mentioned filters, etc., dust adheres to the filters, and the amount of dust adhering increases over time. Problems can occur when the filter is partially blocked and the amount of air passing through it becomes insufficient, or when the weight of the attached dust causes the filter itself to sag, causing the air to pass through the louver without passing through the filter. Therefore, it is necessary to periodically clean the filter to remove adhering dust.

However, in conventional air supply/exhaust louvers, the filter is attached to the filter frame inside the louver with screws, so removing and cleaning the filter is extremely troublesome and difficult to work with, and as a result, regular cleaning is not required. The reality is that people tend to neglect this, resulting in the problems mentioned above.

The present invention was made in view of the above circumstances, and
To provide an air supply/exhaust louver in which a filter can be easily attached and detached to facilitate its cleaning.

"Means and effects for solving the problems" In order to achieve the above object, the present invention provides a method for attaching a louver main body to the outside air side of a louver frame fixed to an opening in a building wall, and A holding frame is provided on the inside so that it can be opened and closed by rotating one side toward the indoor side, and a filter is held in this holding frame so that it can be inserted and removed when the holding frame is in the open state. An insect screen or an insect screen and a shutter are installed between the filter and the holding frame, and when cleaning the filter, the holding frame is opened and the filter can be easily pulled out from the holding frame. It is designed so that it can be held in a holding frame.

"Embodiment" An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In the figure, reference numeral 1 indicates the outer wall of a building made of a concrete wall or a steel frame. A rectangular opening 2 is formed in this outer wall 1. A louver frame 3 is fixedly attached. This glazing frame 3 is either embedded to form the opening 2 during the construction of the outer wall 1, for example, when concrete is poured, or is attached to the opening 2 after concrete is poured, and inside it, A louver main body 4 is provided on the outside air side (left side in FIG. 2), and a holding frame 6 for holding the filter 5 is provided on the indoor side (right side in the same figure). An insect screen 7 is provided on the outside air side between the frame 6 and the shutter 8 on the indoor side.

The above-mentioned louver main body 4 is made up of a plurality of louver blades 10 mounted horizontally on a rectangular picture frame 9 parallel to each other and with predetermined pitches above and below, with one side facing the outside air side. In this state, the picture frame 9 is fitted into the above-mentioned louver frame 3 from the outside air side, and the appropriate parts of the frame 9 are secured to the louver frame 3 by bolts and nuts 11.
It is installed so that it can be attached and detached from the outside air side.

The insect screen 7 is formed by covering a rectangular frame 12 made of magnetic metal with a wire mesh 13 made of stainless steel, and is detachably attached to the louver frame 3 with a magnetic stopper. That is, a mounting seat 14 is fixedly attached to the inner peripheral surface of the louver frame 3, and a permanent magnet 1 is attached to the indoor side surface of the mounting seat 14.
5 is provided. The insect screen 7 is removably attached to the louver frame 3 by adhering the frame 12 to the permanent magnet 15 of the mounting seat 14.

Further, the shutter 8 has a plurality of plate-shaped shutter blades 17 arranged in parallel to each other at a predetermined pitch vertically and rotatably supported on a rectangular cylindrical shutter frame 16 made of magnetic metal. A permanent magnet 18 is provided on one side of the shutter frame 16.
Then, the shutter 8 is inserted and placed in the shutter frame 3 with the one side of the shutter frame 16 facing the insect screen 7, and the permanent magnet 18 of the shutter frame 16
By adsorbing it to the frame 12 of the insect screen 7, it is removably attached within the louver frame 3. or,
Although not shown, each shutter blade 17 is rotated in a vertical plane along the opening direction of the opening 2 via, for example, a worm and a worm wheel, so that the gap between the vertically adjacent shutter blades 17 is adjusted. This allows the amount of air passing through to be adjusted.

On the other hand, the holding frame 6 is removably attached to the indoor side of the shutter 8 with a magnetic stopper via a rectangular attachment frame 19 made of a permanent magnet. This holding frame 6 is made up of a holding frame main body 20 made of magnetic metal and a movable frame 21 rotatably supported at the upper and lower ends of one side edge thereof. When it is rotated in the direction of arrow A in FIG.
It is configured to be in a closed state when it is fitted into the inside, and to be in an open state when rotated in the direction of arrow B in FIG. And the movable frame 21
Insertion grooves 21a that open laterally (to the right in FIG. 1) are formed on the top and bottom, and two sets of filters 5 are inserted into and removed from each of the insertion grooves 21a when the movable frame 21 is open. It is freely inserted and retained.

Although not shown, the holding frame main body 20 is provided with a locking fitting for removably locking the movable frame 21 in its closed state. In addition, 22 in the figure is the outer wall 1
The drainage plate 23, which is provided when the is formed of a steel frame, is a reinforcing angle.

However, in the case of the above air supply and exhaust louver, the second
In the state shown in the figure, the outside air flows as shown by arrow C, and the indoor air flows as shown by arrow D, respectively, for supply and exhaust. They are not blocked and do not enter the room, and the shutter 8 adjusts the amount of air supply and exhaust to an appropriate amount.

Furthermore, although dust in the outside air adheres to the filter 5 and is effectively removed, the amount of dust adhering to the filter 5 increases over time, causing the various problems described above. For this reason, the filter 5 is removed from the holding frame 6 for cleaning, for example, when dirt becomes noticeable when viewed from the indoor side, or periodically, and the attached dust is removed before being reinstalled. At this time, the filter 5 can be easily removed by rotating the movable frame 21 in the direction of the arrow B in FIG. This can be easily done by inserting the movable frame 21 into the insertion groove 21a of No. 21 in the direction of the arrow in FIG. 1 and bringing the movable frame 21 into the closed state. Therefore, the working time is significantly shortened and workability is improved, making it easier to clean the filter 5, and reducing the risk of problems such as a decrease in the amount of air supply and exhaust and a decrease in dust removal efficiency.

In addition, in the air supply/exhaust louver, the insect screen 7 is attached to and detached from the mounting seat 14 of the louver frame 3, the shutter 8 is attached to the insect screen 7, and the holding frame 6 is attached to the shutter 8 via the attachment frame 19 by magnetic locking. Since they are attached freely, they can be easily attached and detached from inside the room. Therefore, in addition to cleaning the filter 5, it is extremely easy to remove these for cleaning or repair. By doing these cleanings, etc.,
This corrosion can be prevented and durability etc. can be improved.

Furthermore, in the above-mentioned air supply/exhaust louver, only the louver frame 3 can be installed when the outer wall 1 is constructed during construction work, and other components such as the louver frame 4 and the insect screen 7 can be sequentially attached after the exterior wall 1 is finished. This is advantageous because there is no fear that members such as the louver body 4 will be soiled with the finishing paint of the outer wall 1 or damaged during construction.

In the above embodiment, the shutter 8 is placed closer to the indoor side than the insect screen 7 in order to make it difficult for insects to attach to the shutter 8, but this arrangement may be reversed.
Further, the insect screen 7, shutter 8, and holding frame 6 are preferably magnetically fastened as described above, but they may be fastened with bolts and nuts, and the louver body 4 may be fixed. Furthermore, although the movable frame 21 of the holding frame 6 is configured to be able to rotate in the horizontal direction in the above example, it may be configured to be able to rotate in the vertical direction.

"Effects of the Invention" As explained above, the air supply/exhaust louver of the present invention is equipped with a filter and an insect screen, and also has a shutter that can be opened and closed between the louver body and the holding frame of the filter, so that rainwater does not enter the louver. It can be used for ventilation, air conditioning equipment, etc. in food and chemical factories, etc. where it is desired to prevent dust, dust, and insects, as well as adjust the amount of ventilation. Moreover, a holding frame is provided on the indoor side of the louver frame so that one side can be opened and closed by rotating it toward the indoor side, and the filter is held in this holding frame so that it can be inserted and removed when the holding frame is in the open state. Therefore, the filter can be easily inserted and removed by opening the holding frame, and cleaning of the filter can be performed extremely easily. Further, by detachably attaching the insect net and shutter to the louver frame using magnetic fasteners, the insect net and shutter can be easily attached and detached, and the insect net and shutter can be easily cleaned and repaired.
