For example, the outdoor unit includes a compressor, an outdoor heat exchanger, and an outdoor ventilation fan, and the indoor unit includes an indoor heat exchanger and an indoor ventilation fan.
When the air conditioner performs cooling operation, the outdoor heat exchanger and the indoor heat exchanger may function as a condenser and an evaporator, respectively. On the other hand, when the air conditioner performs the heating operation, the outdoor heat exchanger and the indoor heat exchanger may function as an evaporator and a condenser, respectively.
The indoor unit further includes a discharge device for guiding the discharge of heat-exchanged air into the predetermined space. For example, the discharge device may be rotatably provided, so that the discharge direction of the air may be variously formed toward a plurality of points of the predetermined space.
The related art documents related thereto are as follows.
1. Public number (public date): 10-2009-0017289 (February 18, 2009)
2. Title of the invention: indoor unit of air conditioner
According to this conventional technique, the phenomenon that the pressure or the air velocity of the air fluctuates, that is, the surging occurs due to the difference between the suction volume of the air sucked into the blowing fan and the discharge volume of the air discharged from the blowing fan, And the performance of the air conditioner is deteriorated due to a decrease in the amount of air.
SUMMARY OF THE INVENTION It is an object of the present invention to provide an indoor unit of an air conditioner capable of reducing noise and improving performance by preventing occurrence of surging.
The indoor unit of the air conditioner according to the embodiment of the present invention includes a case; A suction unit formed at a rear portion of the case and sucking air; A heat exchanger for exchanging heat between the suctioned air and the suctioned air; And a discharge device for discharging the heat-exchanged air in the heat exchanger to an indoor space, wherein the discharge device includes a discharge main body rotatably installed; A blowing fan provided inside the discharge main body and generating a blowing force; A variable vane which is movably provided in a discharge passage of the blowing fan and increases or decreases a size of the discharge passage; And a pressing device which is installed at one side of the discharge main body and selectively presses the variable vane.
The discharge main body includes a rear guide spaced apart from the outer circumferential surface of the blowing fan by a predetermined distance and surrounding the outer circumferential surface of the blowing fan.
Further, the variable vane is provided in the rear guide.
One side of the variable vane is coupled to the rear guide, and the other side of the variable vane is rotatable about the one side.
Further, the variable vane is formed integrally with the rear guide.
The discharge main body further includes an elastic member coupled to the variable vane and providing a restoring force to the variable vane.
In addition, the elastic member includes a compression spring.
Further, the pressing device is provided in a supporter for supporting one side of the discharging device.
The pressing device may further include: a pressing body placed on the upper surface of the supporter; And a pressing portion provided on the pressing body to selectively press the variable vane.
The variable vane includes a contact portion protruding from one surface of the variable vane toward the discharge passage and being pushed by the pressing portion.
Further, the outer peripheral surface of at least one of the pressing portion and the contacting portion has a cam shape.
The above-described ejection apparatus includes first and second ejection apparatuses arranged in a lateral direction in front of the case.
The blowing fan includes a cross flow fan for sucking air in a circumferential direction and discharging the air in the direction of the outer circumference.
The indoor unit of the air conditioner according to another aspect includes: a case; A suction unit formed at a rear portion of the case and sucking air; A heat exchanger for exchanging heat between the suctioned air and the suctioned air; A blowing fan provided at an outlet side of the heat exchanger; A discharge main body rotatably disposed to surround at least a part of the blowing fan and having a discharge portion for discharging air; A first vane provided in the discharge portion and guiding the discharge of air; A second vane movably disposed on one side of the discharge main body; And a pushing device capable of pressing the second vane when the discharge body rotates.
In addition, the first vane is fixed to the discharge portion, and the second vane performs a relative movement with respect to the discharge main body.
The second vane moves in a direction that can increase or decrease the size of the discharge passage of the blowing fan.
In addition, an elastic member is provided to provide a restoring force to move the second vane toward the discharge passage.
Further, the elastic member is provided between one surface of the discharge main body and the second vane.
According to the indoor unit of the air conditioner of the present invention, since the variable vane capable of moving in the rotatable discharge body is provided, the discharge volume can be varied corresponding to the suction volume of the blower to be changed, It is possible to prevent a surging phenomenon that can be generated by the heat sink.
In addition, since the surging phenomenon occurs, noise generated in the indoor unit is reduced, and the amount of air discharged from the indoor unit is increased, so that the performance of the indoor unit can be improved.
The pressing device may further include a pressing device that is capable of pressing the variable vane when the discharge main body reaches a set rotational position, that is, a position where the suction volume increases, There is an effect that the discharge volume can be effectively varied corresponding to the suction volume.
In detail, in the process of rotating the discharge main body, when the suction volume increases, the pushing device presses the variable vane to increase the discharge volume. When the suction volume becomes small, the pushing device is separated from the variable vane The discharge volume can be reduced.
As a result, when the suction volume is formed small, the variable vane can be moved so as to reduce the discharge volume, so that the surging phenomenon can be prevented. Further, when the suction volume is large, the variable vane can increase the discharge volume, so that the discharge air volume can be increased and the performance of the air conditioner can be improved.
Also, since the variable vane is integrally provided in the rear guide of the discharge main body, and the spring is provided between the variable vane and the rear guide, repetitive movement of the variable vane can be facilitated.
