The present invention relates to an air filter assembly comprising an air filter of the air conditioning equipment and a structure for fixing the same, and in particular, its own configuration is simple, easy to assemble, the configuration that can suppress the air flow does not pass through the air filter It is related to the air filter assembly of the air conditioning equipment having a configuration that is convenient to fit the overall size to fit the installation space.

Common air conditioning equipment includes ventilation equipment for air inflow and outflow between indoor and outdoor and air conditioning equipment for heating and cooling. When ventilating the air by the blower fan or generating the air flow for cooling and heating, the air flow passes through the air filter to filter dust or harmful components in the air.

As such, the air filter corresponds to an almost essential element in air conditioning equipment, and its size and degree of filtration vary according to the installation environment. In particular, the air filter of the air conditioning equipment installed in a large equipment industry can be made so large that the length and width of each of several meters (m), it is required to be made according to the respective installation conditions. At this time, the cost and convenience of the operation, the duration of the installation may always be a problem.

In addition, in relation to maintenance, the filter is cleaned or replaced by checking the degree of contamination. In the past, the method of installing the filter itself is not suitable for inspection, cleaning, or replacement, which requires a lot of time and effort. There are many problems that can be damaged in the process, and even if some are damaged, the whole must be replaced.

In addition, the gap between the air filter portion and the vertical frame and the horizontal frame, in particular, the rear end side panels (140a, 140b), the upper upright panel 240 and the lower upright panel 250 and the close contact between the air filter is not made well. Therefore, there was a considerable amount of air leaking through the air filter.

And in order to reduce this problem, by installing a rubber packing such as EPDM in the periphery of the rear of the air filter to suppress the air flow through the contact surface between the air filter and the frame.

However, in the conventional air filter frame, as shown in FIG. 6, only a part of the air filter is fixed by the fixing plate 320 to prevent the filter from escaping from the installation space, and the adhesion between the rubber packing and the air filter is still poor. As a result, air leaks continue to be a problem, and in the semiconductor device process chamber and the liquid crystal display device process chamber requiring high cleanness, such minute leaks may cause problems of cleanliness.

The upper upright panel 540 and the lower upright panel 550 overlap the predetermined width of the upper and lower peripheral portions of the rear of the air filter, and serve to fix and limit the position of the air filter.

The ones at the edge of the entire filter assembly among the horizontal frame and the vertical frame may also have the same configuration as the horizontal frame or the vertical frame in the middle portion. However, here, the horizontal frame and the vertical frame of the edge are a pair of vertical members or one of the horizontal members which is not in contact with the air filter, the rear end side panels 440a and 440b or the upper upright panel and the lower side for restricting the air filter restriction. Since no upright panel is needed, it is formed so as not to have them.

Although not shown, these frames at the edges are in contact with the air filter only on one side, so it is possible to form a vertical frame or a horizontal frame based only on the vertical member or the horizontal member in contact with the air filter.

Meanwhile, in the present invention, when the air filter assembly is viewed in the depth direction, at least one fixing screw 613 and the fixing screw are disposed on the horizontal frame portion and the vertical frame portion surrounding each of the grid spaces formed by the air filter fixing structure. An intermediate member is provided for urging the air filter portion installed in the adjacent lattice space to the rear.

In the embodiment of Fig. 7, a fixing screw 613 is provided at one middle of the horizontal frame portion surrounding the lattice space and at each one of the upper and lower portions of the vertical frame portion, and is opened in contact with the air filter of the tubular washer as an intermediate member. A pressure plate 620 having a plate portion extended to both sides at the end is provided to push the air filter back overall.

7, the rear end side panels 440a and 440b, the upper upright panel 540 and the lower upright panel 550, which extend toward the lattice space in the horizontal frame and the vertical frame and overlap with the periphery of the rear surface of the air filter. The surface is formed of a concave-convex surface having a concave-convex 640, and a flexible packing member 630, such as EPDM rubber, is attached to the rear surface of the air filter in the form of ㅁ to contact the concave-convex surface.

Accordingly, when each fixing screw 613 is tightened at the front side of the air filter assembly, the pressure plate 620 pushes the air filter portions at both sides of the frame portion to which the fixing screw is coupled to the rear, and presses the air filter portions at six positions per air filter. By applying pressure, the rear surface of the flexible packing member 630 positioned between the air filter and the concave-convex surface is in close contact with the concave-convex surface, and the packing member 630 is in close contact with the deformed part of the concave-convex 640 from the rear side.

In particular, the uneven surface of the uneven surface is formed continuously in the form of valleys or acids in a direction perpendicular to the direction in which air passes through the air filter, so that air does not pass through the air filter and bypasses the air filter side to the side of the uneven surface. When trying to escape into the minute gap between the back of the packing member, on the one hand serves to lengthen the passage path by the unevenness, and on the other hand, a stronger pressure is applied between the packing member and the unevenness to close the minute gap. It also plays a more narrowing role. As a result, it can serve to further reduce the amount of air leak.

12 is a cross-sectional view showing a vertical frame, a vertical bracket 710 'and an elastic packing member coupled thereto according to another embodiment of the present invention.

Here, the same as in the previous embodiment, but in most cases, unlike the previous embodiment, there is no closure panel at the rear end in the vertical members 410a and 410b constituting the vertical frame, and only the rear end side panels 440a and 440b are present, and the rear end side. The panels each have protrusion bends 440aa and 440bb protruding rearward from their free ends.

Therefore, a total of two protruding bent portions formed in each of the pair of vertical members constituting one vertical frame constitute one groove, and one plate-shaped vertical bracket 710 'is coupled to the groove.

When there is a strong seal without leaving a gap between the vertical bracket and the groove, the vertical bracket allows air flow through the internal space of the vertical frame as the rear end closure panels 430a and 430b of the previous embodiment overlap to form a sealing member. It can act as a sealing member to prevent. In addition, the vertical bracket 710 'is made of a rigid body can also be a structural action to maintain the separation between the two vertical members constituting the vertical frame in the fitted state. This action is one function of the rear end closure panel of the previous embodiment.

As a result, in this embodiment, in addition to the function of the vertical bracket itself by the groove forming portion formed on the rear end side panel back and the vertical bracket tightly bonded thereto without forming the rear end closure panel, it serves as the rear end closure panel. It may have the effect of simplifying the structure of the air filter fixing structure.

In the above described the present invention through a limited embodiment, but this is only illustrative for the purpose of understanding the present invention, the present invention is not limited to these specific embodiments.

Therefore, one of ordinary skill in the art to which the present invention pertains may make various modifications or applications based on the present invention, and such modifications and applications belong to the appended claims.
