TECHNICAL FIELD

The present disclosure relates to the technical field of air conditioning equipment, in particular to an indoor unit, and an air conditioner including the indoor unit.

BACKGROUND

The fan assembly of conventional wall-mounted air conditioners is typically fixed on the chassis of the housing and provided non-removably. Dust can accumulate on the fan assembly when the air conditioner and such structure therein have been long-term used.
