Description

Ceiling type indoor unit with UV lamp installed}

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

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.

Air conditioners are structurally divided into a separate type in which a compressor is disposed outdoors and an integral type in which a compressor is integrally manufactured.

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

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

In general, the split-type air conditioner is classified according to an installation type of an indoor unit.

An indoor unit installed vertically in an indoor space is called a stand type air conditioner, an indoor unit installed on a wall is called a wall-mounted type air conditioner, and an indoor unit installed on the ceiling is called a ceiling type indoor unit.

In the case of a ceiling-type indoor unit, a suction grill is disposed facing the floor. A filter for filtering foreign substances in indoor air is disposed in the intake grill, and the filter can be separated for cleaning. The user needs to periodically separate the suction grill from the case to clean the filter.

In particular, since the suction grill is disposed on the ceiling of the room, it is difficult for the user to clean it periodically.
