Embodiments disclosed herein may provide an air conditioner having a case and a cover coupled to the case. A cover separation unit may separate the cover from the case at upper and lower sides. The cover separation unit may include a lever that slides along an outer surface of the case and a pusher rotatably coupled to the lever to rotate to push the cover. A guide may guide the pusher to rotate as the pusher is moved along an outer surface of the case.

A blower may include a first case and a second case provided above the first case and having a first tower and a second tower that have a passage therebetween. A display assembly is received in the second case at a position that does not interfere with air flowing in the passage. An inner surface of the second tower and an outer surface of a diffuser define a space in which the display assembly is received.

An air conditioner of the present disclosure includes a base case configured to include a suction port through which air is sucked and accommodate a filter therein, a tower case configured to be disposed above the base case and to include a discharge port through which the air sucked from the suction port is discharged, and a heater configured to be disposed inside the tower case to heat the air.

First and second towers may discharge air. An airflow guide or converter may change a direction of the air discharged from the first tower and the second tower by moving a gate inside and outside of at least one of the first or second towers so as to block discharged air flowing forward and selectively facilitate an upward air flow. The airflow converter may include a guide motor to provide a driving force, the gate, which may reciprocate between the inside and the outside of the first and/or second towers; and a board guider connected to the gate to transmit a driving force of the guide motor to the gate as a linear motion force.

An active airflow inhibiting apparatus for an entranceway comprises: a structure positioned adjacent an entranceway of a building and defines a passage therethrough for accessing the entranceway. The structure defines at least one plenum chamber and first and second outlet slots fluidically coupled to the plenum chamber. A fan fluidically connected to the plenum chamber supplies an airflow to the plenum chamber in order to selectively form a jet of air from the first outlet slot in a first mode of operation and from the second outlet slot in a second mode of operation The first and second outlet slots are configured so that the respective jets of air are each directed towards a centre of the structure, with the jet of air from the first outlet slot being directed away from the entranceway and the jet of air from the second outlet slot being directed towards the entranceway.

First and second towers may discharge air. An airflow guide or converter may change a direction of the air discharged from the first tower and the second tower by moving a gate inside and outside of at least one of the first or second towers so as to block discharged air flowing forward and selectively facilitate an upward air flow. The airflow converter may include a guide motor to provide a driving force, the gate, which may reciprocate between the inside and the outside of the first and/or second towers; and a board guider connected to the gate to transmit a driving force of the guide motor to the gate as a linear motion force.

The present embodiment may comprise: a housing that have a suction port, a space formed therein, and a discharge port formed in an upper portion thereof; a purification unit and a blowing unit accommodated in the space; a discharge guide that is disposed in an upper portion of the housing and discharges blown air to the discharge port; a tilting mechanism that is connected to the discharge guide to tilt the discharge guide; and a lifting and lowering mechanism that lifts and lowers the tilting mechanism.

A blower is disclosed. The blower of the present disclosure comprises: a fan for producing air flow; a lower body providing an inner space in which the fan is installed, and having an intake hole through which air passes; an upper body placed on the lower body to form a flow passage which communicates with the inner space of the lower body, and having a space which is formed to pass through the upper body in the forward and backward direction, wherein the upper body includes a slit which is formed through the upper body and through which air flowing through the flow passage of the upper body is discharged to the space, and the slit comprises: a rear slit adjacent to the rear end of the upper body; and a front slit adjacent to the front end of the upper body.

In an air conditioner, a drain extraction unit and a refrigerant pipe connecting unit may be disposed in a blocking region in which a discharge port is not provided so that a size of the discharge port may be secured and the discharge port may be uniformly disposed, thereby generating uniform airflow in a room. In a lower housing formed in a circular shape, some of components inside an indoor unit of the air conditioner may be disposed in a protrusion portion that protrudes from the circular housing, thereby facilitating the installation of the air conditioner. A condensate water collecting space disposed outside the housing may be provided in a drain tray, thereby efficiently preventing a leakage due to condensate water generated outside the housing. The housing, the drain tray, and the cover member of the air conditioner may be coupled by a coupling member coupled outside.
