The invention provides a wall-hung
indoor air-conditioning unit of an air conditioner. The wall-hung
indoor air-conditioning unit comprises a shell body, a
heat exchanger, an air jet part, a first airsupply
assembly and a second air supply
assembly, wherein the shell body is equipped with a housing and a
front panel; air inlet ports are correspondingly formed in two sides of the housing; a long circular air supply port is formed in the lower part of the
front panel; the
heat exchanger comprises a first heat exchange segment and a second heat exchange segment; the first heat exchange segment is arranged at a position close to the
front panel; the second heat exchange segment is arranged at a position abutting against the top wall of the housing; the air jet part is arranged in the air supply port, and used for jetting heat exchange
airflow forward and bringing
ambient air to be supplied forward; the first air supply
assembly and the second air supply assembly are transversely arrangedbelow the rear part of the
heat exchanger in a spacing manner, and used for producing the heat exchange
airflow; and the heat exchange
airflow enters from the air inlet ports formed in the two sides of the housing, exchanges heat with the heat exchanger, and then is supplied from two sides of the air jet part. By adoption of the wall-hung
indoor air-conditioning unit provided by the invention, theair supply volume can be increased, and then the indoor temperature can be integrally and uniformly reduced; outside air enters a heat exchanger accommodating cavity where the heat exchanger is positioned from two sides, so that the heat exchange airflow can be prevented from being obstructed; and meanwhile, the problem that dust falls into an opening formed in the upper part of the wall-hung indoor air-conditioning unit can be solved.
