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 .

In addition, the multi-type air conditioner is on the increase in size, and the capacity of the outdoor unit is also increasing. Accordingly, the number or size of the fans provided inside the outdoor unit is increased, and noise due to driving of the fan is increased.

In order to solve such a problem, Korean Patent Laid-Open Publication No. 10-2013-0088434 discloses an air conditioner in which a part of a motor mount for supporting a blowing fan is cut out to reduce noise during air flow by a blowing fan.

However, the motor mount according to the prior art has a horizontal bar shape and is disposed so as to traverse the path of the air vertically.

Accordingly, the lower surface of the motor mount and the flowing air collide with the front surface, causing a large air resistance, and the effect of reducing the noise is also remarkable.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an outdoor unit of an air conditioner in which noise generated during rotation of a blowing fan of an outdoor unit can be reduced and the flow of air can be smooth.

An outdoor unit of an air conditioner according to an embodiment of the present invention includes: a case defining a receiving space therein; A fan motor assembly including a motor and a blower fan coupled to a rotating shaft of the motor, the fan motor assembly forcing the flow of air inside the case; And a motor mount mounted on the motor mount, the motor mount including: a pair of fixing parts mounted on the case, forming both ends of the motor mount; A pair of inclined portions extending inward from an inner end of the pair of fixing portions and extending downwardly inclined; And a motor mounting portion connecting the inner ends of the pair of inclined portions and mounting the motor.

The inclined portion is roundly bent at the end of the motor mounting portion, and the fixed portion is roundly bent at the end of the inclined portion.

The rotation axis of the motor is vertically formed on the upper surface of the motor, and the blowing fan forcing the flow of air upwardly from below. The fixing portion is positioned above the motor mounting portion, Is located in the second position.

The outer end of the inclined portion is located below the vertical direction of the blowing fan rotation radius.

The transverse direction width of the inclined portion is formed to be narrower than the transverse width of the motor mounting portion and the fixing portion.

The both end portions of the inclined portion are larger in width in the transverse direction as they are closer to the motor mounting portion and the fixing portion.

And a guide portion formed on the lower surface of the motor mounting portion and extending along the longitudinal direction of the lower surface of the motor mounting portion so as to be narrowed in the downward direction, As shown in FIG.

The guide portion is formed by a plurality of inclined surfaces contacting each other, and each inclined surface is inclined downward as it goes downward.

The guiding portion extends along the longitudinal direction of the lower surface of the motor mounting portion and both end portions of the guiding portion adjacent to the pair of guiding portions are provided with an outer guiding portion inclined toward the guiding portion and guiding air to the guiding portion .

The motor mount is formed by bending a plate material many times and includes a top surface and a bottom surface, a side surface connecting the top surface and one end of the bottom surface, and a space defined by the top surface, the bottom surface, .

A side surface of the motor mount is formed with a forming portion which is recessed in an outward direction along a longitudinal direction of the motor mount.

According to the outdoor unit of the air conditioner of the embodiment of the present invention, the following effects can be expected.

First, the motor mount has a plurality of bent portions, and includes a pair of fixed portions corresponding to both ends and a pair of inclined portions connecting the motor mounting portion corresponding to the center portion. At this time, the inclined portion extends inwardly from the inner end of the fixing portion and extends obliquely to be away from the blowing fan. Therefore, the air resistance is reduced by the inclined portion when the air that flows due to the driving of the fan motor assembly collides with the motor mount, so that the flow of air becomes smooth and noise generation can be reduced.

Secondly, the inclined portion is roundly bent at the end of the motor mounting portion, and the fixing portion is roundly bent at the end of the inclined portion. Therefore, when the flowing air hits the motor mount, the air resistance is more effectively reduced and the noise generation is reduced.

Thirdly, since the motor mounting portion is located below the fixing portion by the inclined portion, the fan motor assembly can be further accommodated in the case, so that the inner space of the outdoor unit can be more effectively utilized.

Fourth, since the fixing portion is positioned above the motor mounting portion, even if the fan motor assembly is further housed in the case, the motor mount having the fan motor assembly can be easily coupled to the case. Therefore, the assembling operation and the AS operation can be easily performed.

Fifth, since the transverse width of the inclined portion is narrower than the transverse width of the motor mounting portion and the fixing portion, the air resistance is more effectively reduced and noise generation is reduced when the flowing air hits the motor mount.

Sixth, a guide portion for guiding air flowing outside to the outside of the motor mounting portion is formed on a lower surface of the motor mounting portion. Therefore, the air resistance is more effectively reduced and the noise generation is reduced when the air to be flowed reaches the lower surface of the motor mount.

Seventh, both ends of the guide portion adjacent to the pair of inclined portions are formed with an outer guide portion inclined toward the inclined portion and guiding the air to the inclined portion. Therefore, a part of the air striking the lower surface of the motor mounting portion is guided to the inclined portion and can be continuously guided by the inclined portion, so that the air flows more effectively and the noise generation is reduced.

Accordingly, when the fan motor assembly 80 drives the air, the air resistance is greatly reduced, and the flow of air can be smooth.

The mounting portion lower surface 112 may include a guide portion 113 formed along the longitudinal direction of the mounting portion lower surface 112 and being pointed toward the lower portion.

The guide portion 113 may be formed so that a plurality of inclined surfaces contact with each other, and each inclined surface may be inclined downwardly as it goes downward.

Meanwhile, the guide portion 113 may include an outer guide portion 114 formed at both ends of the guide portion 113.

The outer guide 114 may be inclined inward as it goes downward. Therefore, the outer guide 114 can guide the air that hits the mounting surface 112 to the inclined portion 120.

According to the structure of the motor mount 100, when the fan motor assembly 80 is driven, the air moving upward from below the motor mount 100 is partially guided by the guide portion 113 And can be guided to the outside of the motor mounting portion 110.

The outer guide portion 114 can guide a portion of the slant 120 to the relatively narrow slant portion 120. As the slopes 120 are rounded and relatively narrow, the air resistance can be minimized when the slopes 120 pass through the slopes 120. Accordingly, the flow of the air inside the outdoor unit 1 can be smooth, and the generation of noise due to the air resistance can be greatly reduced.
