Description

air conditioner

[0001] The present disclosure relates to an air conditioner, and more specifically, to an air conditioner to which a discharge cover is attached.

[0002]

[0003] An air conditioner can supply heat-exchanged air to an indoor space to regulate the temperature of the indoor space.

[0004] Air conditioners mounted on walls or ceilings may have a narrow internal space. Therefore, a cross-flow fan is placed inside, and multiple components placed inside are efficiently arranged.

[0005] Therefore, if workers experience inconvenience or difficulty in installing the internal components of the case, the work speed may be slowed down or misassembly of the components may occur.

[0006] The 'indoor unit of an air conditioner' disclosed in Korean Registered Patent No. 10-2149736 does not specifically disclose the coupling relationship of the components coupled internally.

[0007] The present disclosure aims to solve the aforementioned problems and other problems.

[0008] Another objective is to provide an air conditioner that securely attaches the discharge cover to the case in a simple manner.

[0009] Another objective is to provide an air conditioner that is connected to the case at the top, bottom, and side portions of the discharge cover to enhance fixation.

[0010] Another objective is to provide an air conditioner that improves the strength of the configuration used in confined spaces through a multiple rib structure.

[0011] To achieve the above objective, an air conditioner according to an embodiment of the present disclosure comprises an intake port, a case having a discharge cover hole formed below the intake port, and a discharge cover disposed on one side of the case at the location where the discharge cover hole is formed, having a discharge port formed therein.

[0012] The above case includes an upper front wall positioned above the discharge cover hole, a lower front wall positioned below the discharge cover hole, and side walls extending rearward from each of the upper front wall and the lower front wall.

[0013] The discharge cover comprises an upper part positioned above the discharge port and resting on the upper front wall, a lower part positioned below the discharge port and fixed to the lower front wall, and a side part extending to the rear of the discharge port and fixed to the side wall. When the lower part is fixed to the case, the side part is inserted into one side of the side wall.

[0154] A lower groove (35b1) into which a lower hook (17b) is inserted is formed in the lower wall (35b). An upper groove (35a2) into which an upper hook (17a) is inserted is formed in the upper wall (35a).

[0155] A lower hook (17b) and an upper hook (17a) are positioned on the inner side of the lower front wall (16). The lower hook (17b) and the upper hook (17a) are positioned spaced apart in the left and right directions.

[0156] A lower hook rib (17b1) supporting the placement of the lower hook (17b) is placed on one side of the lower hook (17b). An upper hook rib (17a1) supporting the placement of the upper hook (17a) is placed on one side of the upper hook (17a).

[0157] The side part (36) is positioned above the second discharge port (48). The insertion part (37) and the catch (18a) are positioned above the second discharge port (48).

[0158] Accordingly, the area where the stopper (18a) and the insertion part (37) are placed may be one side of the vane motor that changes the arrangement of the vanes (92, 94). Accordingly, the insertion part (37) and the stopper (18a) connected in a narrow space can be installed in a simple manner.

[0159] With the discharge cover (30) mounted on the case (10), an inner rib (14b) can be placed on the contact wall (32a).

[0160] Although preferred embodiments of the present disclosure have been illustrated and described above, the present disclosure is not limited to the specific embodiments described above. Various modifications are possible by those skilled in the art without departing from the essence of the present disclosure as claimed in the claims, and such modifications should not be understood individually from the technical spirit or perspective of the present disclosure.
