Description

[0001] The present invention relates to an outdoor unit of an air conditioner,

The present invention relates to an outdoor unit of an air conditioner.

The air conditioner is an appliance for keeping the indoor air in the most suitable condition according to the purpose and purpose. For example, in the summer, the room is controlled by a cool air condition, while in winter the room is controlled by a warm heating condition, by the humidity of the room, and by the clean air of the room.

In detail, the air conditioner is driven by a refrigeration cycle for compressing, condensing, expanding and evaporating the refrigerant, thereby performing the cooling or heating operation of the indoor space.

The air conditioner may be divided into a separate type air conditioner in which the indoor unit and the outdoor unit are separated from each other and an integrated type air conditioner in which the indoor unit and the outdoor unit are combined into one unit depending on whether the indoor unit and the outdoor unit are separated. The outdoor unit includes an outdoor heat exchanger that exchanges heat with outdoor air. The indoor unit includes an indoor heat exchanger that performs heat exchange with indoor air.

When the refrigeration cycle is a cooling operation, the outdoor heat exchanger functions as a condenser, and the indoor heat exchanger functions as an evaporator. On the other hand, when the refrigeration cycle performs the heating operation, the indoor heat exchanger functions as a condenser, and the outdoor heat exchanger functions as an evaporator.

On the other hand, in recent air conditioners, a multi-type air conditioner in which a plurality of outdoor units are disposed outside the building such as a roof of a building, and an indoor unit independently cooling and heating each indoor space is connected to the outdoor unit to constitute a refrigerant circuit .

Korean Patent Publication No. 10-2013-0088435 discloses a multi-type air conditioner outdoor unit.

The outdoor unit according to the related art is installed on the upper surface of the base pan so as to constitute a refrigeration cycle including a compressor and is arranged so that the outdoor heat exchanger can be exposed on three sides along the circumference of the base fan. The left and right panels corresponding to the heat exchanger are formed with a left panel and a right panel on the left and right sides, respectively, and a suction grill is formed on the rear panel so that outside air can pass through the outdoor heat exchanger.

Further, the periphery of the outdoor heat exchanger may further include a front panel that forms the front surface and a rear panel that forms a part of the rear surface, including the left panel, the right panel, and the suction grille.

 And a top panel on which an air discharge hole for discharging air upward is formed on an upper surface of the outdoor unit. At this time, the peripheries of the top panel are bent and can be combined with the left panel, the right panel, the front panel and the rear panel forming the periphery of the outdoor unit.

The periphery of the top panel is bent to have a structure for housing the left panel, the right panel, the front panel and the rear panel. The folded portion and the left panel, the right panel, the front panel, And can be coupled to each other by a plurality of screws passing through the rear panel.

However, a coupling structure is not provided between the periphery of the top panel and the left panel, the right panel, the front panel, and the rear panel, so that the circumference of the top panel and the space between the left panel and the right panel, There is a problem that a gap is generated.

In order to solve such a problem, the number of fastening points of the screw must be increased but the appearance of the screw is deteriorated due to an increase in the number of fastening points of the screw, A problem occurs.

It is an object of the present invention to provide an outdoor unit of an air conditioner which can prevent external appearance of an outdoor unit from occurring and minimizes the use of a screw to improve appearance and improve productivity.

Hereinafter, an assembling process of the top cover of the outdoor unit 1 having the above-described structure will be described.

FIG. 9 is a sectional view showing the mounting process of the top cover in order.

The mounting process of the top cover 10 will be described with reference to the drawings.

Various configurations including a compressor (51) and an outdoor heat exchanger (55) for constituting a refrigeration cycle are installed on the upper surface of the base pan (40). The side supporters 20 are coupled to four corners of the base pan 40. A plurality of out panels 30 are mounted between the side supporters 20 and the suction grill 33 is mounted Thereby forming an appearance. Next, the control box 56, the fan motor assembly 80, the shroud 90, and the like are mounted. The top cover 10 is mounted on the opened upper end of the outdoor unit 1 to complete assembly.

In order to assemble the top cover 10, the top cover 10 is first folded to the upper portion of the outboard panel 30 and the bent portion 300 at the upper end of the side supporter 20 as shown in FIG. 9 (a) Respectively.

When the top cover 10 is further moved downward in this state, the rim portion 12 moves along the outer surfaces of the outboard panel 30 and the side supporter 20, The bent portion 300 of the outboard panel 30 and the side supporter 20 is adjacent to the plate portion 11 of the top cover 10 as shown in FIG.

At this time, the end of the first extended portion 302 of the bending portion 300 is supported by the forming portion 14 or the restricting portion of the depression 13, and is not released. Therefore, due to the pressure applied to the second round portion 121, the second extended portion 122, the upper surface of the outer surface of the outboard panel 30, and the upper surface of the outer surface of the side surface supporter 20, it is possible to maintain a completely close state as shown in FIG.

Particularly, in such a structure, since the downward pressing force is always applied by the self weight of the top cover 10, the bending part 300 maintains a state of being in close contact with the inside of the rim 12.

Thus, the top cover 10 can be fixedly inserted into the outboard panel 30 and the side supporter 20. Therefore, the fixing state can be maintained without a separate coupling member, and a coupling member coupled with each panel constituting the out panel 30 may be partially fastened to maintain a more rigid coupling state.
