Description

TECHNICAL FIELD

BACKGROUND

Air-conditioners control the temperature of indoor air to a temperature set by a user and cool and heat indoor air according to the principle of a refrigeration cycle. In particular, an air-conditioner in which an indoor unit is installed vertically in an indoor space is referred to as a stand-alone air-conditioner, an air-conditioner in which an indoor unit is installed on an indoor wall is referred to as a wall-mounted air-conditioner, and an air-conditioner in which an indoor unit is installed on an indoor ceiling is referred to as a ceiling-type air-conditioner.
The `link structure of an air-conditioner' disclosed in Korean Application Publication No. 10-1998-0049068 includes a plurality of louvers coupled to a discharge port side; and a link that integrally rotates the plurality of louvers, in which the plurality of louvers are formed in a flat plate shape with a uniform thickness throughout.
In the related art air-conditioner, the plurality of louvers move to form a discharge flow path and come closer to an inner wall to adjust a wind direction. At this time, as the louver located at the edge among the plurality of louvers moves closer to the inner wall, and a flow path between the louver at the edge and the inner wall becomes narrow, causing a vortex. This causes a problem in that a discharged air flow does not flow smoothly.
In addition, the related art air-conditioner has a problem in that the vortex occurring at the edge of the discharge flow path is not discharged quickly through the discharge port due to the plurality of louvers, causing dew formation on the louvers.
In addition, the related art air-conditioner has a problem in that bacteria, such as mold, grow due to condensate formed in the louvers. This may cause an unpleasant odor occurring in the discharged air flow.
