The present invention relates to an indoor unit for an air conditioner, and more particularly, a bell mouse for guiding the flow of intake air sucked into the indoor unit is easily and firmly mounted to the air inlet by using a snap fit as a fastening means. It is equipped with a suction grill on the bell mouse to act as a safety net to prevent it from coming close to the internal parts.The air purifier that performs the air cleaning function is mounted on the bell mouse as a snap fit as a fastening means to cover the front of the inlet port. The present invention relates to an indoor unit for an air conditioner capable of reducing the cost by improving the cleanability and reducing the cost of parts and assembly.

An air conditioner is a device that controls air temperature, humidity, air flow, and cleanliness to create a pleasant indoor environment. The air conditioner cools and heats the room through a refrigeration cycle consisting of an evaporator, a condenser, a compressor, and an expansion valve. It is equipped with air purification function to clean the air cleanly, and it is largely divided into separate type and integrated type. The separate type and the integrated type are functionally the same, but the separate type connects the indoor unit and the outdoor unit separated by a refrigerant pipe by installing a cooling / heating unit in the indoor unit, and a heat radiating / cooling and compression unit in the outdoor unit. It is installed directly by integrating the function of heat dissipation by drilling holes in the walls of houses or hanging devices on windows. Recently, in consideration of three-dimensional cooling and heating, there is a tendency to form an air discharge port through which air is discharged to the side or upper surface of the indoor unit.
