Description

Filter assembly for air conditioner

The present invention relates to a filter assembly for an air conditioner, and in particular, by combining two covers having the same shape and structure so as to be detachable, the case can be easily configured and the filter means can be used freely and semi-permanently. The present invention relates to a filter for an air conditioner, in which a plurality of filters can be easily bundled together to form a single filter assembly, so that the filtering area can be freely adjusted according to the size of the air conditioner without design change.

An air conditioner is a name for a device or a facility that is installed in not only buildings but also various means of transportation to maintain the temperature of the surrounding air at an appropriate level for people to feel comfortable. It is hard to imagine that modern people live in an environment without an air conditioner. It is widely used.

The air conditioner basically sucks the surrounding air, heats it with the heat exchanger, and discharges it to the outside. The air conditioner functions as a cooler when the temperature of the heat exchanger is lower than the temperature of the ambient air, and as a heater when the air conditioner is high. .

On the other hand, the air passing through the air conditioner is provided with a large number of suspended matter such as fine dust, such dust is likely to accumulate in the spaces between the minute gaps, for example, the cooling fins formed on the surface of the heat exchanger. This accumulation of dust deteriorates the efficiency of the air conditioner. On the other hand, most of the air conditioners are equipped with filters because the dust accumulated inside the air conditioner is a factor that can pollute the air.

1 shows an example of an air conditioner 1 equipped with such a filter. The air conditioner 1 shown in the drawing is an air conditioner installed in a large building such as a building, and a filter case 3 in which a filter is stored upstream of the air flow, that is, the inlet port 2 where external air is sucked in. Is equipped. However, the conventional filter case has some problems.

The first is that it has a difficult structure to recycle. The conventional filter case is made of a lightweight aluminum angle frame, and a grid and a filter made of wire which prevents the filter from falling off to the open side of the frame are stored. The filter case was completed by bending the corners. However, the filter case of such a structure is not only difficult to replace and expensive to replace the filter, but also has a disadvantage in that productivity is reduced because it includes the task of preparing a separate grid and bending the frame when making the case.

In addition, depending on the size of the air conditioner, the installation of only one filter case often fails to satisfy the required filtering area. On the other hand, since the size of the filter case is standardized for compatibility, it is not possible to arbitrarily change the size of the filter case. Therefore, several filter cases are collected and used together. However, conventionally, in order to collect and install a plurality of filter cases, it was inconvenient to prepare individual cases according to the specifications of the air conditioner, which also acted as a factor to increase the cost.

The present invention has been made to solve the problems of the conventional filter as described above, it is an object of the present invention to provide a filter assembly for an air conditioner excellent in recyclability can be made easily and freely replace the filter means.

It should be noted, however, that such definitions of relative positions may be altered in an equivalent arrangement without changing the essential parts of the invention.

As shown in Figures 2 and 3, the air conditioner filter 10 according to the present invention is a grating (110) consisting of intersecting cross and longitudinal bar and a frame 120 surrounding the grating (110) It is made of a plate-shaped body consisting of a first cover 100 having a step 122 formed along the edge of the frame 120 and a second cover 200 having the same shape and structure as the first cover 100. Each of the first and second covers 100 and 200 has a female coupler 126 and a male coupler 130 formed therein, and the female / male coupler 126 and 130 and the second cover of the first cover 100 are respectively formed. The male / female coupling spheres 130 and 126 of the 200 are respectively coupled to each other. When the first and second covers 100 and 200 are coupled to each other, an accommodating space is formed therein by a step 122 formed at an edge of the frame 120. The accommodating space includes a filter means 300, for example, a nonwoven fabric. By storing, the filter 10 installed in an air conditioner is completed.

A feature of the air conditioner filter 10 according to the present invention is that the first cover 100 and the second cover 200 have the same shape and structure, thereby increasing productivity, and in particular, the injection molding covers the covers 100 and 200. Since manufacturing requires only one type of mold, the production cost is greatly reduced. In addition, since the component type of the filter 10 is simplified, the convenience of inventory management and maintenance is also very high.

However, in the first cover 100 and the second cover 200, the stepped portions 122 formed at the corners of the frame 120 face each other, that is, the cover of any one of the first and second covers 100 and 200 is turned upside down. The shape of the frame 120 and the arrangement of the female coupler 126 and the male coupler 130 must follow a special rule because they must be coupled in a true state. Referring to this rule, firstly, the frame 120 has a shape in which both parts separated by a virtual line are point symmetrical with respect to a reference point on a virtual line that is a straight line crossing the opposite edges. A female coupler 126 is formed on one of both portions of the frame 120 divided by lines, and the other coupler has a male coupler to form point symmetry with the female coupler 126 about the reference point. 130) should be provided. For example, if the shape of the frame 120 is a circle, the imaginary line becomes the diameter and the reference point is the center of the circle, and the female coupler 136 and the male coupler 130 are two semicircles divided by the imaginary line. Each of the female coupler 126 and the male coupler 130 are formed in the area, and the positions of the female coupler 130 and the male coupler 130 must be arranged to be point symmetrical about the center of the circle. As another example of the embodiment of the present invention shown in FIGS. 2 and 3, when the frame 120 has a rectangular or square shape, the imaginary line becomes a diagonal line and the reference point becomes a midpoint of the diagonal line. The female coupler 126 and the male coupler 130 are respectively formed in two right triangle regions divided by an imaginary line, but the positions of the female coupler 126 and the male coupler 130 are located at a diagonal midpoint. To be point symmetrical with respect to each other, for example, it should be arranged along the edge of the frame 120 as shown in the illustrated embodiment. Of course, in this case, the imaginary line does not have to be diagonal, just across the opposite edges. The shape of the frame 120 may have various shapes other than circles and squares, and the filter 10 of the present invention may be configured by two covers having the same shape if the above two rules are satisfied.

4A and 4B show an embodiment applicable to the female coupler 126 and the male coupler 130 included in the filter 10 of the present invention. The female coupler 126 and the male coupler 130 coupled in pairs, as shown in Figure 4a, the male coupler 130 is a screw 130 'and the female coupler 126 is a hole ( 127 may be a formed boss 126 ′. According to this embodiment, the male screw of the screw 130 ′ penetrates into the inner circumferential surface of the hole 127 formed in the boss 126 ′ and generates a strong friction force, thereby making a firm coupling. In addition, the female coupler 126 and the male coupler 130 as shown in FIG. 4B are also possible. In this embodiment, the male coupler 130 is a cutout groove 131 formed along the longitudinal direction of the body having a cylindrical shape. ) And a one-touch pin 130 ″ having a wedge-shaped coupling jaw 132 formed at an end of the body, and the female coupling hole 126 is formed with a recess 129 in which the coupling jaw 132 is caught. And a boss 126 ″ having a through hole 128. The advantage of the embodiment shown in FIG. 4B is that the one-touch pin 130 ", which is simply the male coupler 130, can be penetrated by the boss 126 " When inserted into the hole 128, the engaging jaw 132 of the one-touch pin 130 "is caught by the recessed portion 129 of the boss 126" so that the fastening is easily performed.

And in order to assist the first and second covers 100 and 200 to be coupled while the female coupler 126 and the male coupler 130 are exactly paired in one embodiment of the present invention, a virtual line as shown in FIG. 3. A portion of the frame 120 may be configured to have a step 124 higher than the rest of the frame 120 to achieve point symmetry around the reference point of the image. In particular, the shape of the frame 120 is coupled to the female coupler 126 and the male coupler 126 in the case that the first / second cover (100, 200) has a shape that can be superimposed on the appearance even without rotating 180 °, such as circular or square It is useful in that it can induce an accurate bond between the spheres 130.

In addition, the present invention may include a configuration for preventing the flow of the filter means 300, in particular the nonwoven fabric accommodated in the receiving space formed inside the first / second cover (100, 200). That is, the lattice (110) consisting of intersecting horizontal and vertical ribs has a point symmetry around the reference point, and at the intersection of the horizontal and vertical ribs at either of the two parts separated by the imaginary line, The protrusion 112 may be formed to protrude, and a pinhole 114 may be formed at the intersection of the other portion to fix the pin 112. Accordingly, when the fixing pin 112 penetrating the filter means 300 is fitted in the pin hole 114 while the first and second covers 100 and 200 are coupled, the filter means 300 is connected to the fixing pin 112. Is fixed to prevent flow.

Alternatively, it is possible to protrude the fixing pin 112 'having a sharp tip along the frame 120 to prevent the flow of the nonwoven fabric, which is the filter means 300, which is shown in FIG. . Fixing pin 112 'having a tip is advantageous in that it is possible to omit the configuration of the pinhole 114, and it is sufficient to form the fixing pin 112' only at one of the two parts separated by the imaginary line. Do.

Meanwhile, the air conditioner filter 10 according to the present invention may form a single air conditioner filter assembly 1000 by tying together several pieces without preparing a separate case according to the size of the air conditioner.

The frame 120 of the first and second covers 100 and 200 for constituting the air conditioner filter assembly 1000 has a square or rectangular shape, and four corners of the frame 120 are centered at their vertices. Quadrant jaw 400 is formed. The other configuration except for the configuration in which the quadrant tuck 400 is formed is the same as the configuration of the above-described air conditioner filter 10, and thus description of overlapping portions will be omitted.

In the air conditioner filter assembly 1000 illustrated in FIG. 5, four air conditioner filters 10 having a quadrant jaw 400 formed at four corners of the frame 120 are arranged in a 2 × 2 structure. Four quadrant jaws 400 met at the center of the four air conditioner filters 10 form a circular jaw 400 '. Here, if the circular jaw 400 'made by four 2 × 2 structural arrangements of the air conditioner filter 10 is fixed with a strap-shaped fastener 500, the four air conditioner filters 10 The air conditioner filter assembly 1000 is formed without being stored in a separate case. At this time, the binding hole 500 may be a steel band 500 'that can adjust the binding force by rotating the screw or tightened in one direction and a band clip 500 ", also known as a cable tie, may be used. Since the band clip 500 "is already well known, a description thereof will be omitted.

It should be noted, however, that in the above description that the four air conditioner filters 10 are arranged in a 2 × 2 structure, it means a minimum structure for forming a circular jaw 400 ″. As shown in Fig. 6, various arrangements are possible such that sixteen air conditioner filters 10 are arranged in a 4 × 4 structure to be applied to a large air conditioner, in particular the filter assembly 1000 for an air conditioner according to the present invention. The advantage is that as the number of filters 10 increases, the number of circular jaws 400 ″ also increases, so that even if the size of the air conditioner filter assembly 1000 increases, it is possible to maintain structural stability. This can be easily seen by confirming that the number of circular jaws 400 ″ in the 2 × 2 and 4 × 4 structures respectively shown in FIGS. 5 and 6 has greatly increased from one to nine.

Meanwhile, the air conditioner filter assembly 1000 ′ according to the present invention includes an air conditioner filter 10 and an air conditioner filter 10 in which the frame 120 has a square or rectangular shape as shown in FIG. 7.
