Description

Outdoor unit for an air conditioner {An outdoor unit for a an air conditioner}

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

An air conditioner is a device for maintaining air in a predetermined space in a state most suitable for use and purpose. In general, the air conditioner includes a compressor, a condenser, an expansion device, and an evaporator, and a refrigeration cycle for performing the compression, condensation, expansion, and evaporation processes of the refrigerant is driven to cool or heat the predetermined space. .

The predetermined space may be variously proposed according to the place where the air conditioner is used. For example, when the air conditioner is disposed in a home or an office, the predetermined space may be an indoor space of a house or a building. On the other hand, when the air conditioner is disposed in a car, the predetermined space may be a boarding space in which a person boards.

When the air conditioner performs the cooling operation, the outdoor heat exchanger provided in the outdoor unit functions as a condenser, and the indoor heat exchanger provided in the indoor unit performs an evaporator function. On the other hand, when the air conditioner performs a heating operation, the indoor heat exchanger functions as a condenser and the outdoor heat exchanger functions as an evaporator.

On the other hand, the outdoor unit of the air conditioner may be provided with a suction panel for forming an outside air suction unit. The formation position of the outside air suction unit may be determined corresponding to the area or size of the heat exchanger installed in the outdoor unit. As the heat exchanger and the outside air suction unit become larger, the heat transfer area may increase, thereby having good performance.

However, in a state in which the overall size of the outdoor unit is predetermined, if any one of the plurality of components installed in the outdoor unit is larger, the other component is inevitably smaller. Therefore, optimizing the size or position of the plurality of parts may be an important factor in increasing the performance of the outdoor unit.

In particular, the heat exchanger and the blower fan, which are one of the main parts of the outdoor unit, may be located adjacent to each other in function. In detail, the blowing fan may be disposed on the outlet side of the heat exchanger, for example, on the upper side of the heat exchanger based on the air flow.

If the vertical height of the heat exchanger is increased in order to increase the heat transfer area, the vertical height of the blower fan is inevitably reduced. As a result, the area of the heat exchanger is increased, but the air volume of the blower fan is reduced, thereby reducing the overall performance of the outdoor unit.

Regarding the structure of the outdoor unit, the present applicant has filed and registered the following prior document.

By the configuration of the protrusion 207, the strength in the bending direction of the motor mount 200 can be increased. The protrusion 207 may be referred to as a "reinforcement rib."

The bracket fastening part 240 may include a first fastening part 241 extending in a vertical direction to cover an end side of the third part 230 and a horizontal extension from the first fastening part 241. 2 fastening part 245 is included.

Bracket fastening hole 242 into which the first fastening member 281 is inserted into the first fastening portion 241 to fasten the motor mount 200 to the cabinets 30, 40, and 50 of the outdoor unit 10. ) May be formed. The second fastening part 245 may be supported by the panel coupling part 255 of the mount bracket 250.

FIG. 8 is a view illustrating a fan assembly installed in a cabinet of an outdoor unit according to an embodiment of the present invention, and FIG. 9 is a cross-sectional view taken along line IX-IX 'of FIG. 8.

8 and 9, the fan assembly of the present invention may be disposed to be supported by the cabinets 30, 40, and 50 of the outdoor unit 10.

In detail, the mount bracket 250 may be fastened to the suction panel 30 or the control panel 40 by the first fastening member 281. A plurality of first fastening members 281 may be provided, and the plurality of first fastening members 281 may be spaced apart from each other in the left and right directions. In addition, the mount bracket 250 may be provided at front and rear portions of the outdoor unit 10 to be fastened to the cabinets 30, 40, and 50.

In addition, since the first fastening member 281 is fastened inward from the outside of the mount bracket 250 and coupled to the motor mount 200, assemblability may be improved.

The mount bracket 250 may be supported on an upper surface of the heat exchanger 60. As described above, since the heat exchanger 60 is formed to be relatively bulky and bent to have four sides, the heat exchanger 60 may stably support the mount bracket 250.

The connection bracket 156 of the orifice 150 protrudes from the orifice body 151 by the second fastening member 283 and may be fastened to the suction panel 30 or the control panel 40. A plurality of second fastening members 283 may be provided, and the plurality of second fastening members 283 may be spaced apart in the left and right directions. The connection brackets 156 may be provided at front and rear portions of the outdoor unit 10, and may be fastened to the cabinets 30, 40, and 50.

In addition, since the second fastening member 283 is fastened inward from the outside of the connection bracket 156, assemblability may be improved. The second fastening member 283 may be disposed above the first fastening member 281.

The fan motor 120 may be supported by the first part 210 of the motor mount 200. The third part 230 may be disposed at a position higher than the first part 210 to be supported by the cabinets 30, 40, and 50 of the heat exchanger 60 or the outdoor unit 10. That is, the distance H1 from the first part 210 to the bottom of the blade 115 is greater than the distance H2 from the third part 230 to the bottom of the blade 115. It can be formed large.

According to this configuration, since the gap between the blade 115 of the blower fan 110 and the first part 210 is formed relatively large, it is possible to prevent the resistance of the air flow from being increased by the motor mount 200. have. That is, when the distance between the motor mount 200 and the blade 115 becomes small, the air flow becomes unstable due to vortices and the like around the motor mount 200, and the suction efficiency to the blower fan 110 decreases. The present embodiment can avoid this problem.

The height of the vertical reference center C of the fan motor 120 may be higher by H3 than the first part 210 and lower by H4 than the height of the upper end T1 of the heat exchanger 60. have.

That is, at least a portion of the fan motor 120 may be located in the inner space of the bent heat exchanger 60, thereby reducing the height of the fan assembly protruding upward of the heat exchanger 60. have. In addition, since the lower portion of the fan motor 120 may be supported by the motor mount 200, the fan motor 120 may be stably supported.
