The present invention relates to an air filter used in an air conditioning facility, and more particularly, to an air filter for air conditioning, which improves structural rigidity and stability of a filter frame and enables a clean installation without the need for finishing a collection bag.

Industrial facilities, public facilities and buildings are equipped with air conditioning facilities for air purification, and air ducts are installed with air ducts used to filter harmful substances such as fine dust and pollutants contained in the air.

The exhaust duct in which the air filter is installed sucks air with a strong suction force, and therefore, the frame constituting part of the air filter must be structurally stable and rigid.

In particular, the air filter is provided with a plurality of collecting bags, the inlet frame used to maintain the inlet shape of the collecting bag should be free of deformation during use. If the deformation occurs, even collection effects are not obtained.

 The entrance frame is also to be structurally stable. Otherwise, it may cause vibrations and cause noise.

In addition, since the inlet of the collecting bag is positioned around the inlet frame, a closing member is required to neatly handle the finishing of the inlet of the collecting bag.

The present invention was devised in view of the above circumstances, and an object of the present invention is to provide an air filter for air conditioning, which improves the structural rigidity and stability of the filter frame and enables a clean installation without the need for finishing the collection bag.

Specific means of the present invention for achieving the above object,

A main frame having an air inlet;

It is composed of a plurality of single filters disposed in the air intake,

The single filter,

It consists of a collecting bag and a collecting inlet frame installed at the inlet of the collecting bag,

A reinforcing member for reinforcement is achieved by assembling the joint between adjacent collection inlet frames.

The reinforcing member applied to the present invention further includes a reinforcing blade bent inward at both ends as a V-shaped length member.

At this time, the reinforcing member of the reinforcing member is preferably fitted to the bent end bent to the front end of the collecting inlet frame is configured to prevent the departure from assembly.

In addition, according to the present invention, the collection bag may be configured to be fitted and fixed between the grooves and grooves formed between the adjacent collection inlet frame.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 and 7, the air filter 1 includes a main frame 10 having an air intake 12.

The main frame 10 is made of a metal plate material in the present embodiment is configured in the form of a quadrangular strip, but is not limited to this form. The main frame 10 has a cross-section formed in a 'c' shape as shown in FIG. 3 and is formed with reinforcement wings 11 bent inward at both ends.

The reinforcement wing 11 is formed continuously along the circumference of the main frame 10 and serves to increase the structural rigidity of the main frame 10.

As shown in FIGS. 1 and 2, a plurality of single filters 20 are closely arranged side by side in the air inlet 12 of the main frame 10.

The single filter 20 consists of a collecting bag 22 and a collecting inlet frame 24 provided at the inlet of the collecting bag 22.

The collection bag 22 is composed of a nonwoven fabric, microfiber, etc. The present invention is not limited to this material.

The collection inlet frame 24 is made of a metal sheet and is formed in a rectangular shape.

Reinforcing members 30 are assembled at adjacent abutment portions between the collection inlet frames 24.

The reinforcing member 30 is a reinforcing blade 32 bent inwardly at both ends as a length member having a substantially V-shaped cross section, as shown in Figs. 2, 4 and 5, the reinforcing blade 32 is It is fitted to the bent end (24a) bent to the front end of the collection inlet frame 24 serves to prevent the separation of the reinforcing member 30 assembly.

On the other hand, the present invention, as shown in Figure 6, the collection bag 22 is sandwiched between the concave-convex (25a) and the groove (25b) formed in the longitudinal direction between the adjacent collection inlet frame 24, the collection bag 22 easily It may be configured not to exit from the collection inlet frame 24.

The air conditioner of the present invention configured as described above is assembled as follows.

First, a collection bag 22 is opened to one side is prepared.

Next, the collecting bag 22 is connected to the collecting inlet frame 24. In this case, the connecting means may be, for example, an adhesive or a punching pin 40. In this way, a plurality of single filters 20 provided with a collecting inlet frame 24 are provided at the inlet of the collecting bag 22.

The single filters 20 are then arranged side by side on one plane and then connected to the junction between adjacent collection inlet frames 24 using a substantially U-shaped punching pin 40. Here, the punching pin 40 is installed through the neighboring port collecting inlet frame 24 by the punching force.

Next, the reinforcing member 30 prepared at the junction of the neighboring collecting inlet frame 24 is inserted into the joint as shown in FIG. 5, and then compressed and the reinforcing blade 32 is fitted to the bent end 24a of the collecting inlet frame 24. Let's do it.

At this time, the crimping of the reinforcing member 30 may be made locally at regular intervals, or the whole may be compressed.

In this way, several single filters 20 are assembled to each other. At this time, the inlet of the collecting bag 22 is covered by the reinforcing member 30 is neatly finished as shown in FIG. Therefore, even when the inlet end of the collecting bag 22 is further raised when connecting the collecting bag 22 to the collecting inlet frame 24, it is possible to reduce the inconvenience of cutting it out.

The single filter 20 assembled as described above is assembled to the air intake 12 formed in the main frame 10 as shown in FIG.

The air filter 1 for the air conditioner 1 constructed and assembled as described above has a reinforcing member 30 assembled to the collecting inlet frame 24 so that structural reinforcement is achieved and resistance to bending force is increased, so that deformation is reduced and structural stability is achieved. do.

In addition, the resistance to the bending force becomes stronger, it is possible to eliminate the occurrence of vibration of the collecting inlet frame (24).

In this way, the collection inlet frames 24 have increased rigidity by the reinforcing member 30 to eliminate the change in the inlet of the collection bag 24, so that the collection inlet pockets 22 are evenly collected in several collection bags 22 installed in one air filter 1. You can expect.

In addition, as shown in Figure 5, the reinforcing member 30 does not interfere with the air flow is sucked, there is no noise.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto, and the technical idea and the following of the present invention are provided by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.

As described above, according to the air conditioning air filter of the present invention, the reinforcing member is assembled to the collecting inlet frame without affecting the collecting flow, thereby increasing structural stability and rigidity. Therefore, there is no change in the collecting inlet, and evenly collecting effects can be expected, so that the life can be prolonged much and vibration can be prevented.

In addition, once assembled reinforcement member is prevented from being separated by the bent reinforcement wings can improve the quality of the air filter product.

In addition, the inlet end of the collection bag is covered by the reinforcing member to not only have a neat finish but also does not need to cut the fabric of the bag even if it comes out as long as conventional.
