Description

An outdoor unit for an air conditioner

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

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

For example, when the air conditioner is disposed in a home or office, the predetermined space may be an indoor space in a house or building. On the other hand, when the air conditioner is disposed in a vehicle, the predetermined space may be a boarding space for people to board.

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 functions as an evaporator. 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 forming an outdoor air suction unit. The formation position of the outdoor air suction unit may be determined according to the area or size of the heat exchanger installed inside the outdoor unit. When the heat exchanger and the outside air suction part are increased, the heat transfer area is increased to have good performance.

However, in a state in which the total size of the outdoor unit is predetermined, when one of the plurality of components installed in the outdoor unit becomes larger, the other component is forced to be smaller. Therefore, optimizing the size or location 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 blower fan may be disposed on the outlet side of the heat exchanger based on air flow, for example, on the upper side of the heat exchanger.

If the height of the heat exchanger is increased to increase the heat transfer area, the height of the blower fan must be reduced. As a result, the area of the heat exchanger is increased, but the air volume of the blower fan becomes small, so that the overall performance of the outdoor unit may decrease.

With regard to the structure of the outdoor unit, the applicant has applied for and registered the following prior documents.

The protrusions 207 provided in each of the extensions 213, 223, and 233 may be integrally configured. By the configuration of the protrusion 207, the strength in the bending direction of the motor mount 200 may be increased. The protrusion 207 may be referred to as “reinforcement rib”.

The bracket fastening part 240, the first fastening part 241 extending in the vertical direction to cover the end side of the third part 230 and the first extending in the horizontal direction from the first fastening part 241 Two fastening parts 245 are included.

A bracket fastening hole 242 into which the first fastening member 281 for fastening the motor mount 200 to the cabinet 30, 40, 50 of the outdoor unit 10 is inserted in the first fastening part 241 ) May be formed. In addition, the second fastening part 245 may be supported by the panel coupling part 255 of the mount bracket 250.

8 is a view showing a fan assembly according to an embodiment of the present invention installed in a cabinet of an outdoor unit, 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 arranged to be supported on 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 in the left and right directions. In addition, the mount bracket 250 is provided in the front and rear portions of the outdoor unit 10, respectively, it can be fastened to the cabinet (30,40,50).

In addition, as the first fastening member 281 is fastened in the inner direction from the outside of the mount bracket 250, it is coupled to the motor mount 200, thereby improving assembly performance.

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

The connecting bracket 156 of the orifice 150 protrudes from the orifice body 151 by a second fastening member 283 and can be fastened to the suction panel 30 or the control panel 40. A plurality of the 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, respectively, and may be fastened to the cabinets 30, 40, and 50.

In addition, since the second fastening member 283 is fastened in an inner direction from the outside of the connection bracket 156, assembling performance may be improved. In addition, the second fastening member 283 may be disposed above the first fastening member 281.

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

According to this configuration, since the gap between the blade 115 of the blower fan 110 and the first part 210 is relatively large, it is possible to prevent the resistance of 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 decreases, air flow becomes unstable due to vortices around the motor mount 200 and the suction efficiency to the blowing fan 110 decreases. It can be, this embodiment can prevent this problem.

In addition, the height of the vertical center C of the fan motor 120 in the vertical direction may be higher than H1 by 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 upwards 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.
