technical field

The invention relates to an air conditioner, in particular to a heat insulation structure of an opening and closing part arranged at an outlet of the air conditioner.

Background technique

As a device that properly adjusts the indoor temperature to provide a comfortable indoor environment, the air conditioner utilizes a refrigeration cycle for cooling or heating. Air conditioners generally consist of indoor units and outdoor units according to their functions and locations.

The indoor device is to exchange the inhaled indoor air through the built-in heat exchanger and then discharge it. In the past, air outlets were formed only on one side of the indoor unit, but recently, indoor units that are formed on multiple sides to discharge air in multiple directions have been developed.

Among these existing air conditioners, one example is a three-side discharge type air conditioner. The two sides of the housing of the air conditioner protrude obliquely, and a front discharge port is formed above the front of the housing, and the two sides of the front discharge port respectively form discharge ports. And, the side discharge port is provided with a rotatable shutter door (louver) for opening and closing the discharge port; and the front discharge port is opened and closed by a front discharge port door which is arranged on the front of the housing and can be raised and lowered.

During the operation of the air conditioner, the front discharge port and the side discharge port can be controlled to open and close separately. That is, open and close only the front discharge port or the side discharge port to centrally cool or heat the target space; or open all the front discharge ports and side discharge ports to uniformly cool or heat the target space.

When intensive cooling is performed by opening only the front outlet, the side outlet is closed by the louver door. But at this time, the warmer indoor air outside the louver is cooled by the cold air inside the louver, causing condensation to form on the surface of the louver. This dew condensation will contaminate the exterior of the air conditioner and the indoor floor, thereby causing a problem of polluting the indoor environment.
