The present invention relates to an air conditioner, and more particularly, to an air conditioner that can easily change a cooling capacity to a small capacity or a large capacity while sharing a plurality of parts.

When manufacturing an air conditioner, a large air conditioner having a cooling capacity and a small capacity air conditioner having a small cooling capacity are manufactured. It allows the user to choose what they need by considering the cooling capacity.

In general, a large capacity air conditioner is used for cooling a large space, so the heat exchange unit and the blower fan are large, and a small capacity air conditioner is used for cooling a relatively small space, and thus the heat exchange unit or blower fan is small. Of course, the large-capacity air conditioner and the small-capacity air conditioner have different sizes and sizes of the main body, because the sizes of the internal parts are different. Therefore, when manufacturing these air conditioners, a large capacity and a small capacity were designed separately, and the manufacturing process was also different.

However, when the small-capacity air conditioner and the large-capacity air conditioner were manufactured separately, each part had to be manufactured separately because the size of each part was different and it was difficult to share the parts with each other. Therefore, there is a problem that the manufacturing cost of the air conditioner is high and the productivity is low.

The present invention is to solve such a problem, it is an object of the present invention to provide an air conditioner that can share a large number of parts and can easily change the cooling capacity to a small capacity or a large capacity.

Air conditioner according to the present invention for achieving this object and the front case; A rear case coupled to the rear of the front case; A heat exchanger installed inside the front case; A condensate receiver installed under the heat exchanger; A blowing fan installed between the heat exchanger and the rear case; And a stabilizer installed in the condensate receiver so as to be close to the blower fan, and the rear case includes a first rear case and a second rear case which are formed to have different sizes and are selectively mounted on the front case. And a first blower fan and a second blower fan which are formed in different sizes for selective mounting, and the stabilizer receives the condensate receiver to adjust its position according to the selective mounting of the first and second blower fans. It is characterized in that coupled to the position adjustable.

In addition, the first rear case and the second rear case is characterized in that the same coupling position with the front case.

In addition, the stabilizer is provided with a plurality of positioning grooves formed at positions spaced apart from each other for the variable position, the condensate receiving is characterized in that it comprises a plurality of positioning projections selectively coupled to the plurality of positioning grooves. .

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

As shown in FIG. 1, FIG. 2, and FIG. 4, the air conditioner according to the present invention includes a front case 10 and a rear case 20 coupled to the rear of the front case 10. Inlet openings 11a and 11b for suctioning indoor air are formed on the upper and front surfaces of the front case 10, and discharge holes 12 are formed below the front case 10 to discharge the harmonized air into the room. . The heat exchanger 13 and the blower fan 30 are installed inside the front case 10 and the rear case 20.

The heat exchanger 13 is installed inside the front case 10. The heat exchanger 13 is installed to be close to the upper and lower inlets 11a and 11b to allow all of the sucked air to pass therethrough. This heat exchanger 13 cools or heats the air by causing the air to exchange heat in contact with the surface thereof. The front of the heat exchanger 13 is provided with a filter 14 for filtering foreign matter.

The blowing fan 30 is installed in a space between the heat exchanger 13 and the rear case 20. The blowing fan 30 is a normal cross flow fan. Although not shown in the drawing, the blower fan 30 is rotated by driving motors installed in the front and rear cases 10 and 20.

The condensate receiver 40 is installed below the heat exchanger 13. The condensate receiver 40 collects and discharges condensate flowing from the heat exchanger 13 and guides the air blown from the blower fan 30 to the discharge port 12. The condensate receiver 40 extends from the inner surface of the front case 10 toward the blowing fan 30 and forms a receiving space for accommodating condensate thereon. The condensate receiver 40 may be integrally formed with the front case 10 through injection molding.

The stabilizer 50 is installed at the rear end of the condensate receiver 40 adjacent to the blowing fan 30. The stabilizer 50 forms a flow branch point of the air blown by the blower fan 30 to guide the blown air to the discharge port 12. When installing the stabilizer 50, it is necessary to properly adjust the distance from the blower fan (30). If the interval is small, the blowing effect is improved, but noise is likely to occur, and if the interval is too wide, the blowing effect is reduced. Therefore, the interval between the stabilizer 50 and the blowing fan 30 is appropriately adjusted in consideration of the size and operating speed of the blowing fan.

As shown in FIG. 1, the rear case 20 includes a first rear case 21 and a second rear case 22 that can be selectively mounted on the front case 10. The blower fan 30 also includes a first blower fan 31 and a second blower fan 32 that can be selectively mounted.

The first blowing fan 31 is relatively larger in diameter than the second blowing fan 32. Therefore, when the first blowing fan 31 rotates at the same speed as the second blowing fan 32, it may blow more air. The first rear case 21 is also formed larger than the second rear case 22. As shown in FIG. 2, the first rear case 21 forms an installation space in which the first blowing fan 31 may be installed between the first rear case 21 and the front case 10. Moreover, the inner surface 23 forms the blowing flow path which guides the air blown by the 1st blowing fan 31 to the discharge port 12. As shown in FIG. This is to allow the first blowing fan 31 and the first rear case 21 to be paired to be mounted to the front case 10.

As shown in FIG. 4, the second rear case 22 forms an installation space for installing the second blowing fan 32 between the front case 10 and the front case 10. The inner surface 24 forms a blowing passage for guiding the air blown by the operation of the second blowing fan 32 to the discharge port 12. This is also to allow the second blowing fan 32 and the second rear case 22 to be mounted on the front case 10 in pairs. The air flow passage formed by the inner surface of the second rear case 22 may be different in size from the air flow passage formed by the first rear case 21. This is because the blowing characteristics of the first blowing fan 31 and the second blowing fan 32 are different.

These configurations are designed to be equipped with a first blower fan 31 and the first rear case 21 in the front case 10, as shown in Figure 2 when a large air conditioner having a large cooling capacity is to be configured When a small capacity air conditioner having a relatively low cooling capacity is to be constructed, as shown in FIG. 4, the second blower fan 32 and the second rear case 22 may be mounted to the front case 10. It would be. That is, a large capacity air conditioner and a small capacity air conditioner can be selectively manufactured while sharing a large number of parts on the front case 10 side.

For this configuration, the positions 25 and 26 (see FIG. 2) where the front case 10 and the first rear case 21 are coupled are positions 27 where the front case 10 and the second rear case 22 are coupled. And 28, see FIG. 4). That is, the first and second rear cases 21 and 22 are provided with the same coupling portion between the upper part and the lower part. In addition, the first blowing fan 31 and the second blowing fan 32 have the same position where the respective rotating shafts are coupled. However, the position in which the rotation shaft is coupled may be the front case 10 or the rear cases 21 and 22.

The stabilizer 50 is coupled to the rear end of the condensate receiver 40 so as to be changeable in the front-rear direction. This is to adjust the distance between each blowing fan (31, 32) and the stabilizer (50) by different mounting positions when the first blowing fan (31) is mounted and the second blowing fan (32) is mounted, respectively. will be.

For this configuration, the stabilizer 50 has an upper coupling portion 51 and a lower coupling portion 52 for coupling with the condensate receiver 40, as shown in FIGS. 3 and 5. In addition, the upper coupling portion 51 is formed with a first positioning groove 53 and a second positioning groove 54 spaced apart from each other in the moving direction of the stabilizer 50, the lower coupling portion 52 is also a stabilizer ( The third positioning groove 55 and the fourth positioning groove 56 are spaced apart from each other in the moving direction of 50. In addition, the rear end of the condensate receiver 40 coupled to the stabilizer 50 may protrude upward from the upper surface for selective coupling with the first and second positioning grooves 53 and 54 of the upper coupling part 51. Positioning protrusions 42 and the second positioning protrusions spaced apart from each other in the moving direction of the stabilizer 50 for selective engagement with the third and fourth positioning grooves 55 and 56 of the lower coupling portion 52. 43 and the third position adjusting projection 44 are provided.

Therefore, when manufacturing a large-capacity air conditioner by mounting the first blower fan 31 having a relatively large diameter on the front case 10, as shown in Figure 3, by pushing the stabilizer 50 in the direction of the arrow A stabilizer ( 50) and the distance between the first blowing fan 31 can be adjusted. At this time, the stabilizer 50 has a first position adjustment groove 53 in the first position adjustment protrusion 42, a third position adjustment groove 55 in the second position adjustment protrusion 43, and a fourth position adjustment groove ( 56 are respectively coupled to the third positioning protrusions 44. And the stabilizer 50 is maintained in a fixed state at the end of the condensate receiver 40 in the position adjustment is completed.

On the other hand, as shown in FIG. 4, when the small capacity air conditioner is manufactured by mounting the second blowing fan 32 having a smaller diameter on the front case 10, as shown in FIG. 5, the stabilizer 50 ) In the direction of arrow B to adjust the gap between the stabilizer 50 and the second blowing fan 32. At this time, the stabilizer 50 has a second positioning groove 54 is coupled to the first positioning projection 42, the fourth positioning groove 56 is coupled to the second positioning projection 43. And in this state of the position adjustment is completed stabilizer 50 is also maintained in a fixed state at the end of the condensate receiver (40).

When the air conditioner is manufactured in this manner, a large capacity air conditioner as shown in FIG. 2 or a small capacity air conditioner as shown in FIG. 4 can be easily manufactured. Compared to the large capacity air conditioner of FIG. 2, the small capacity air conditioner of FIG. 4 may have a thinner thickness in the front and rear directions, and the cooling capacity may be reduced by reducing the air volume.

As described in detail above, the air conditioner according to the present invention can configure a large air conditioner having a large cooling capacity by mounting the first blowing fan and the first rear case in the front case and adjusting the interval of the stabilizer, the front case A small capacity air conditioner with a small cooling capacity can be constructed by attaching a second blower fan and a second rear case to the stabilizer. Therefore, it is possible to share a large number of parts, such as heat exchanger, filter, condensate receiver, stabilizer of the front case, but it is easy to manufacture a large or small capacity air conditioner as needed.

In addition, the present invention can simplify the manufacturing process of the air conditioner and reduce the manufacturing cost because it can share a large number of parts while manufacturing a large capacity or small capacity according to the cooling capacity.
