Description

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

The present invention relates to an indoor unit of an air conditioner, and more particularly, to a ceiling-type indoor unit installed in a ceiling of an indoor unit.

Generally, an air conditioner is composed of a compressor, a condenser, an evaporator, and an inflator, and supplies air or warm air to a building or a room using an air conditioning cycle.

The air conditioner is structurally divided into a separable type in which the compressor is disposed outdoors and an integral type in which the compressor is integrally manufactured.

In the separate type, an indoor heat exchanger is installed in an indoor unit, an outdoor heat exchanger and a compressor are installed in an outdoor unit, and two devices separated from each other are connected to each other by a refrigerant pipe.

In the integrated type, the indoor heat exchanger, the outdoor heat exchanger and the compressor are installed in one case. The integrated type air conditioner includes a window type air conditioner for directly mounting the apparatus on a window, and a duct type air conditioner for connecting the suction duct and the discharge duct to the outside of the room.

The separate type air conditioner is generally classified according to the installation type of the indoor unit.

A stand-type air conditioner in which an indoor unit is vertically installed in an indoor space is referred to as a stand-type air conditioner. A wall-mounted type air conditioner in which an indoor unit is installed on a wall of the room is called a ceiling-type indoor unit.

There is also a system air conditioner which is capable of providing air-conditioned air in a plurality of spaces as one type of a separate type air conditioner.

In the case of a system air conditioner, there is a type in which a plurality of indoor units are provided to air-condition the room, and a type in which air-conditioned air is supplied to each space through the duct.

A plurality of indoor units provided in the system air conditioner may be equipped with a stand type, a wall type or a ceiling type.

In the conventional ceiling-type indoor unit, one vane is provided at the discharge port, and the flow direction of the discharged air is controlled by adjusting the rotation angle of the vane.

However, in the conventional ceiling-type indoor unit, since the discharge direction of the air is controlled by only one vane, there is a limitation in controlling the direction of the discharged air.

First, the case where the indoor unit is in a stopped state will be described with reference to FIG.

When the indoor unit is not operated, the discharge vane 200 covers the discharge port 102 in the state shown in Fig. 4, and is housed in the discharge flow path 104.

When the indoor unit is not operated, the driving link 310 is horizontally disposed by the rotation of the vane motor. The vane link guide 350 is positioned below the driving link 310 and the longitudinal direction of the driving link 310 and the longitudinal direction of the vane link guide 350 are orthogonal or intersecting. Likewise, the vane link 320 is positioned below the driving link 310, and the longitudinal direction of the driving link 310 and the longitudinal direction of the second vane link 340 may be intersecting or orthogonal.

When the indoor unit is not operated, the longitudinal direction of the second vane link 340 and the longitudinal direction of the vane link guide 350 are arranged in parallel in this embodiment.

When the indoor unit is not operated, the second drive link engagement portion 312 is positioned inward (on the intake port 101 side) with respect to the vane link guide 350, and the first drive link engagement portion 311 is positioned on the outer side (On the side of the advancing direction of the discharge air).

When the indoor unit is not operated, the outer end of the vane 210 is positioned to face upward. The outer end 211 of the vane 210 is positioned higher than the inner end 212.

When the indoor unit is operated, the outer end 211 of the vane 210 is moved downward.

When the indoor unit is not operated, the vane 210 forms a continuous surface with the cover panel 120 and blocks the inside of the discharge port 102 from being exposed to the outside.

Next, a case in which the indoor unit is operated in the stopped state will be described with reference to Fig.

When the indoor unit is operated, the indoor blower 140 is operated to circulate indoor air, and the discharge air is discharged through the discharge port 102. [ To this end, the vane motor 220 rotates the driving link 310 in a counterclockwise direction, and the vane 210 is rotated along a predetermined orbit by the counterclockwise rotation of the driving link 310.

The vane 210 is rotated while being moved to the lower side of the discharge port 102.

When the vane 210 rotates, the outer end 211 of the vane 210 is lowered to open the discharge port 102.

FIG. 8 is an exemplary view showing a state in which a discharge vane forms a horizontal wind according to an embodiment of the present invention. FIG. 9 is an exemplary view showing a state in which a discharge vane forms a vertical wind according to an embodiment of the present invention.

When the vane 210 forms a horizontal wind, the outer end 211 of the vane 210 may be disposed horizontally with the ground or the ceiling. When the vane 210 forms a horizontal wind, the outer end 211 of the vane 210 may be arranged to be slightly lower in the horizontal direction with respect to the ground or the ceiling.

The inner end 212 and the outer end 211 of the vane 210 are both positioned below the discharge port 102 when the vane 210 forms a horizontal wind.

The inclination of the vane 210 can be adjusted by adjusting the rotation angle of the driving link 310 and the horizontal wind can be formed according to the inclination of the vane 210.

When the vane 210 forms a horizontal wind, the relative rotation shaft 325 is positioned inward (on the side opposite to the traveling direction of the discharge air or on the suction port side) with respect to the vane link guide 350.

On the other hand, when the vane 210 forms a vertical air flow, the relative rotation shaft 325 is located outside (in the direction of the discharge air) with respect to the vane link guide 350.

When the vane 210 forms a vertical wind, the outer end 211 of the vane 210 may be vertically arranged vertically with the ground or the ceiling. When the vane 210 forms a vertical wind, the outer end 211 of the vane 210 may be disposed to face the ground.

The inner end 212 of the vane 210 is located inside the discharge passage 104 and the outer end 211 is located below the discharge passage 104 when the vane 210 forms a vertical wind .

When the vane 210 forms a vertical wind, it is positioned on the suction port 101 side with respect to the vane link guide 350.

The vane 210 is arranged vertically downward from the cover panel 120 when the vertical airflow is formed and the inlet port 101 and the outlet port 102 are disposed on one side. And the discharge port 102 can be separated from each other. So that it is possible to prevent the discharge air from being sucked directly into the suction port 101 even if vertical wind is formed.

8, the driving link 310 is further rotated counterclockwise to form a horizontal wind.

When the driving link 310 is further rotated counterclockwise, the relative rotation shaft 325 is rotated counterclockwise about the first driving link coupling portion 311, and the vane link guide 350 is rotated And is located outside.

The first vane link shaft 321 is moved and rotated along the vane link guide 350 so that the vane 210 is rotated clockwise and the vane 210 is inclined vertically .
