Description

Filter fixtures that can fix the filter of the filter frame structure of the air conditioner with a constant torque {FILTER FIXING APPARATUS FOR FITTING FILTER IN FRAME STRUCTURE IN AIR CONTACTORS}

The present invention relates to a filter frame structure of an air conditioner, and in particular, when a filter is installed on the front of the frame structure, a certain torque is applied to the filter fixture so as to have uniform resistance to wind supplied from the outside to increase the installation tension of the filter. It relates to a filter fixture capable of fixing a filter of a filter frame structure of an air conditioner that can be uniformly adjusted with a constant torque.

In general, an air conditioner is a device that combines one or more casings with mechanical devices necessary to achieve the purpose of air conditioning, such as cooling, heating, dehumidification, humidification, and air purification.

Such an air conditioner is composed of a casing, a fan and a motor, a filter, a damper, a coil, and an eliminator.

Here, the filter has a function of purifying dust and pollutants of the air flowing into the air conditioner and entering the room or work place, the damper controls the amount of inflow or soil air, and the coil flows into the air conditioner. It is a part that heat-exchanges the amount of heat transferred from the heat source equipment (boiler, refrigerator) to the air. Most air conditioners' coils are Fin & Tube method is used.

For example, in Korean Utility Model Publication No. 20-0214038, it is possible to selectively apply it as needed, and it is very easy to manufacture and install, providing excellent compatibility, thereby reducing cost as well as maximizing work efficiency. In addition, an assembly structure of an air conditioning filter that can be effectively maintained and repaired by partial replacement is described.

However, the first prior art such as this requires n plate-shaped frames and n angles, which increases the number of components of the frame structure, and there is a gap between the plate-shaped side frame and the support in the longitudinal direction. Even if the seals were sealed, they had the disadvantage of being structurally susceptible to leakage.

In addition, the Republic of Korea Utility Model Publication No. 20-0328837 can be selectively applied as needed, and it is very easy to manufacture and install, providing excellent compatibility, reducing cost as well as maximizing work efficiency. An assembly structure of an air-conditioning filter that enables effective maintenance and repair by partial replacement and a more robust support in the assembled state is described.

However, since the second prior art such as this requires assembling the frame and the support using an angle of an a-shaped shape, workability is poor when assembling, and the assembly angle is shifted when fixing the angle and the frame or support, causing the entire structure to be twisted. It could be a prone problem.

In addition, Korean Patent Publication No. 10-1824701 states that the filter is easy to assemble and can be appropriately applied and installed according to the installation environment or the size of the air-conditioning space, providing excellent compatibility. A filter frame structure for an air conditioner that can be reduced to and improved airtightness is disclosed.

However, in this third prior art, each vertical member has a front end closure panel, and a pair of vertical members are abutted to overlap the front end closure panels and are sealed by a sealing material at the junction to close the front end. In addition, each vertical member has a rear end closing panel, and since the rear end closing panels are overlapped with each other and sealed with a sealing material at the junction to close the rear end and assemble, the assembling property has not been greatly improved.

In addition, one or more spacers are provided to maintain a constant spacing between vertical members coupled to one or more of the side surfaces opposite to each other of the pair of vertical members, and the horizontal frame includes a bottom surface and/or a lower surface of the upper panel. With one or more ribs extending transversely from the upper surface of the panel, the number of components as a whole has not been significantly reduced compared to the prior art.

In order to solve such problems of the prior art, Korean Patent Publication No. 10-1983749 (May 23, 2019) discloses that the number of components of the frame structure can be reduced compared to the prior art, while improving the assembling property and durability of the frame structure. As a result, a frame structure for mounting a filter of an air conditioner is described that can reduce the overall assembly time as well as lower the overall product price.

However, the first to fourth prior art techniques such as these cannot uniformly adjust the installation tension of the filter when the filter is installed on the front or rear of the frame, there is a problem that the normal filtering function and efficiency are inferior.

The reason is that the filter installed on the filter holding frame is manually fixed using a clamp. Since the clamping position is different depending on the overall size of the filter, not only the grip force exerted by human hands is different, but also all clamps even in similar positions. This is because it was not possible to uniformly adjust the fixed position of the body only by the senses.

Accordingly, it is not possible to provide a uniform surface tension against the air breeze supplied at a constant pressure from the outside, resulting in deterioration of the normal filtering function and deterioration of efficiency.

Republic of Korea Utility Model Publication No. 20-0328837 Republic of Korea Utility Model Publication No. 20-0328837 Republic of Korea Patent Publication No. 10-1824701 Republic of Korea Patent Publication No. 10-1983749
