Description

Indoor unit of air conditioner

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

In general, an air conditioner is composed of a compressor, a condenser, an evaporator, and an expander, and supplies cold or warm air to a building or room using an air conditioning cycle.

Structurally, the air conditioner is divided into a separate type in which the compressor is disposed outdoors and an integral type in which the compressor is integrally manufactured.

In the separation type, an indoor heat exchanger is installed in an indoor unit, an outdoor heat exchanger and a compressor are installed in the outdoor unit, and two separated devices are connected through a refrigerant pipe.

The integral type is an indoor heat exchanger, an outdoor heat exchanger and a compressor installed in one case. The integrated air conditioner includes a window type air conditioner which is installed directly by hanging the device on a window, and a duct type air conditioner which is installed outside the room by connecting an intake duct and a discharge duct.

The separation type air conditioner is generally classified according to an installation form of the indoor unit.

When the indoor unit is installed vertically in the indoor space, it is called a stand-type air conditioner, when the indoor unit is installed on the wall of the room is called a wall-mounted air conditioner, and when the indoor unit is installed on the ceiling, it is called a ceiling-type indoor unit.

Also, as a type of a separate type air conditioner, there is a system air conditioner capable of providing air-conditioned air to a plurality of spaces.

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

The plurality of indoor units provided in the system air conditioner may be any of a stand type, a wall mounted type, or a ceiling type.

In the case of a conventional ceiling-type indoor unit, one vane is installed at a discharge port, and a rotation angle of the vane is adjusted to control the flow direction of the discharged air.

However, since the conventional ceiling-type indoor unit controls the air discharge direction with only one vane, there is a limited problem in controlling the air discharge direction.

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

The suction port 101 and the discharge port 102 are both disposed on one side, and when forming the vertical wind, the vane 210 is vertically disposed downward from the cover panel 120, and the suction port 101 and the discharge port 102 may be separated. Through this, even if a vertical wind is formed, it is possible to suppress direct suction of the discharge air into the suction port 101 .

In the state of FIG. 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 around the first driving link coupling part 311, and the vane link guide 350 is rotated. It passes through and is located outside.

Correspondingly, the first vane link shaft 321 is moved and rotated along the vane link guide 350, the vane 210 is rotated clockwise, and the vane 210 is vertically inclined in the vertical direction. is regulated

The driving link 310 may adjust the rotation angle to adjust the inclination of the vane 210 , and may form a vertical wind according to the inclination of the vane 210 .

When the vane 210 forms a vertical wind, the driving link 310 is arranged in the vertical direction, and the vane 210 is also arranged in the vertical direction.

When the vane 210 forms a vertical wind, the driving link 310 may be disposed side by side with the vane link guide 350, and among the first vane link 330 or the second vane link 340 . Either one may be arranged horizontally.

When the vane 210 forms a vertical wind, the vane 210 is disposed to protrude below the cover panel 120 , and the air discharged from the discharge port 102 through this is directly directed to the suction port 101 . flow can be inhibited.

Although the embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above embodiments, but may be manufactured in various different forms, and those of ordinary skill in the art to which the present invention pertains. It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without changing the technical spirit or essential features of the present invention. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
