Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

Disclosed herein is an air conditioner including a suction panel which includes a suction port through which air is suctioned in inside a housing. The suction panel is formed to rotate with an axial direction of an air blowing fan or a direction perpendicular to the axial direction of the air blowing fan as a rotation axis to be coupled with or separated from the housing. Accordingly, a user may easily and intuitively separate the suction panel and falling of the suction panel, which may occur when the suction panel is separated, may be effectively reduced using a supporting unit disposed at the suction panel. Also, the housing and cover members which cover an outer perimeter of a lower portion of the housing may be coupled with each other by pressurizing the cover members toward the housing, thereby allowing the user to easily coupled the cover members.
