Abstract

An outdoor device for an air conditioner and a method for manufacturing a side supporter for an outdoor device for an air conditioner are provided. The outdoor device may include a top cover that forms an upper surface of the outdoor device and in which a plurality of discharge ports is formed, a base pan that forms a lower surface of the outdoor device, an outdoor heat exchanger that extends along a periphery of the base pan, a plurality of side supporters that connects the top cover and the base pan and forms corners of the outdoor device, and a plurality of outer panels provided between the plurality of side supporters and coupled to the plurality of side supporters to form a shape of an outer periphery of the outdoor device. A plurality of suction ports, through which outside air may be suctioned, may be formed in a region of the plurality of outdoor panels corresponding to the outdoor heat exchanger, including the plurality of side supporters.

First claim

What is claimed is:

1 . An outdoor device of an air conditioner, comprising:
a top cover that forms an upper surface of the outdoor device and in which a plurality of discharge ports is formed; a base pan that forms a lower surface of the outdoor device; an outdoor heat exchanger that extends along a periphery of the base pan; a plurality of side supporters that connects the top cover and the base pan and forms corners of the outdoor device; and a plurality of outer panels provided between the plurality of side supporters and coupled to the plurality of side supporters to form a shape of an outer periphery of the outdoor device, wherein a plurality of suction ports, through which outside air is suctioned, is formed in a region of the plurality of outer panels corresponding to the outdoor heat exchanger, and wherein each of the plurality of side supporters includes an inclined surface forming a surface inclined between outer surfaces of neighboring ones of the plurality of outer panels.

2 . The outdoor device according to claim 1 , wherein extending surfaces are formed at both side ends of the inclined surface, and wherein each of the extending surfaces is bent multiple times to be coupled to the plurality of outer panels, respectively.

3 . The outdoor device according to claim 2 , wherein each of the extending surfaces includes:
a first side surface bent at the respective side end of the inclined surface and coplanar with an outer surface of the respective outer panel; a second side surface bent from the first side surface toward an inside of the outdoor device and then extended; and a coupling portion bent from the second side surface toward the outside to be coupled to the respective outer panel.

4 . The outdoor device according to claim 3 , wherein the second side surface and the coupling portion extend substantially perpendicular to each other.

5 . The outdoor device according to claim 1 , wherein a first side surface is bent at both side ends of the inclined surface, which is coplanar with the respective outer surface of a respective outer panel of the plurality of outer panel, and wherein the first side surface forms a portion of a peripheral surface of the outdoor device.

6 . The outdoor device according to claim 1 , wherein a distance between a pair of bent portions that extend, respectively, from side ends of the inclined surface is larger than a lateral width of the inclined surface.

7 . The outdoor device according to claim 1 , wherein vertical grooves spaced apart from each other are formed between an outer surface of each side supporter and an outer surface of a respective outer panel of the plurality of outer panels.

8 . The outdoor device according to claim 1 , wherein a periphery of the top cover is bent and receives upper ends of the plurality of side supporters.

9 . The outdoor device according to claim 8 , wherein a bent portion is provided at an upper end of the inclined surface to support a lower surface of the top cover.

10 . The outdoor device according to claim 1 , wherein a plurality of supporter suction ports, which are opened along the inclined surface and supply outside air toward the outdoor heat exchanger, is formed on the inclined surface of each supporter.

11 . The outdoor device according to claim 10 , wherein the plurality of supporter suction ports is formed between the plurality of suction ports of the plurality of outer panels provided at both sides of the respective supporter.

12 . The outdoor device according to claim 11 , wherein the plurality of supporter suction ports has a same length as a length of a suction port positioned at a same height.

13 . The outdoor device according to claim 10 , wherein the plurality of supporter suction ports is formed in a region between the base pan and one or more shroud provided above the outdoor heat exchanger to guide discharge of air.

14 . The outdoor device according to claim 10 , wherein the plurality of supporter suction ports is formed in each of the plurality of side supporters provided in a position corresponding to a bent corner of the outdoor heat exchanger among the plurality of side supporters.

15 . An air conditioner including the outdoor device according to claim 1 .

16 . A method of manufacturing a side supporter for an outdoor device for an air conditioner, comprising:
supplying a metal sheet having a predetermined length and width; cutting an end of the metal sheet by press working, and molding at least one coupling hole or at least one engaging portion configured to be coupled to an end of an outer panel of an outdoor device, in a coupling portion of a side supporter; and forming a pair of extending surfaces in the side supporter by press working, and bending the extending surfaces multiple times so that the plurality of extending surfaces includes an inclined surface configured to form a corner of an outdoor device of an air conditioner, wherein the bending of the plurality of extending surfaces multiple times includes inserting at least one cam punch into a space formed when the pair of extending surfaces is bent, and then slidably moving the at least one cam laterally to mold the pair of extending surfaces.

17 . The method according to claim 16 , wherein the forming and the bending includes:
primarily bending the pair of extending surfaces so that a first side surface and the coupling portion of the side supporter are bent at a predetermined angle; secondarily bending the pair of extending surfaces so that the first side surface is perpendicular to the inclined surface and the first side surface is perpendicular to the coupling portion; and thirdly bending the extending surfaces so that the inclined surface is bent to have a predetermined inclination relative to the first side surface.

18 . The method according to claim 16 , wherein the at least one cam punch includes a pair of cam punches, which is slidably moved in such a manner that the pair of cam punches moves closer to each other when the pair of cam punches is inserted into the space formed when the pair of extending surfaces is bent and move away from each other after the pair of extending surfaces is processed.

19 . The method according to claim 18 , wherein an escape distance depressed in each of the pair of cam punches in order to mold the pair of extending surfaces is formed to be smaller than a sliding distance of each of pair of cam punches.

20 . The method according to claim 18 , wherein the pair of cam punches bends the respective extending surface on one side, and then bends the extending surface on the opposite side again.

21 . The method according to claim 16 , wherein a distance between the pair of extending surfaces is larger than a width of the at least one cam punch.

22 . A side supporter manufactured using the method according to claim 16 .

23 . An outdoor device of an air conditioner including a plurality of the side supporter according to claim 22 , wherein the plurality of side supporters forms corners of the outdoor device.

24 . An air conditioner including the outdoor device according to claim 23 .

25 . A side supporter for an outdoor device for an air conditioner, the side supporter comprising:
an angled surface that extends along a vertical length thereof; a pair of extending surfaces that extends from lateral side ends of the angled surface and is bent multiple times, wherein each
