Abstract: An air conditioner of present invention comprises a housing having an outer panel forming the exterior and an opening formed on the outer panel, a heat exchanger configured to exchange heat with air flowing into the housing, and a door unit configured to open or close the opening by moving forward or backward from the opening through which the heat exchanged air is discharged. Wherein the door unit comprises a door blade configured to open or close the opening, a door operating part configured to move the door blade forward or backward, and a controller configured to control the air discharged from the opening to be moved forward from the opening in a straight line or to be discharged radially from the opening by controlling a distance between the door blade and the opening.

Abstract: An air conditioner according to the present disclosure includes a housing provided with an outer panel forming an appearance, and an opening formed in the outer panel; a heat exchanger configured to exchange heat with air introduced to the inside of the housing; a first discharge portion connected to the opening to discharge heat-exchanged air to the outside; a second discharge portion disposed in a lower side of the first discharge portion in the outer panel to discharge the heat-exchanged air; and a blowing fan disposed inside of the housing to move air, which is heat-exchanged by the heat exchanger, in a direction of the second discharge portion.

Abstract: An air conditioner includes a housing comprising an external panel defining an external appearance and having an opening formed at the external panel; a heat exchanger configured to exchange heat with air flowing into the housing; and an air discharge unit configured to discharge air heat-exchanged by the heat exchanger out of the housing. The air discharge unit includes a first discharge unit connected to the opening and discharging air; and a second discharge unit provided at the external panel and discharging air. A method of blowing heat-exchanged air may be changed in accordance with an environment of a user.

Abstract: An air conditioner includes a main body, a blower fan disposed in the main body, a discharge panel including a main outlet configured to discharge air discharged from the blower fan and a plurality of fine outlets provided near the main outlet, an opening and closing member configured to move in forward and backward directions and open and close the main outlet, and a lighting apparatus disposed on a back surface of the opening and closing member and configured to emit light to a back side thereof. Since an area illuminated by the lighting apparatus is changed according to a position of the opening and closing member, a user intuitively identifies an operational state of the air conditioner.

Abstract: An air conditioner includes a dust collecting space so that foreign substances inside the air conditioner may be easily removed. The air conditioner includes a case, a front panel having a plurality of holes formed to discharge air to the front of the case, and a dust container provided inside the case to communicate with some of the plurality of holes.

Abstract: An air conditioner includes a housing, a heat exchanger arranged to exchange heat with air flowing into the housing, a blower fan arranged inside the housing for discharging air that has exchanged heat with the heat exchanger to the outside and a discharging plate having an opening formed to discharge air blown from the blower fan out of the housing, and a plurality of discharging holes formed to discharge air to surroundings of the opening, wherein the discharging plate is arranged to discharge the air that has exchanged heat by the heat exchanger out of the housing, and wherein the discharging plate is made of metal. By such configuration, air conditioner increase user satisfaction.

Abstract: An air conditioner includes a cabinet, a particle sensing unit coupled to the cabinet and configured to measure a particle concentration of an outside, and an inlet provided at the cabinet and configured to communicate with the outside so that particles flow into the particle sensing unit, and the particle sensing unit includes a first particle sensor configured to sense particles flowing in through the inlet, and a second particle sensor coupled to form a connection path in which particles move between the first particle sensor and the second particle sensor to sense the particles passing through the first particle sensor. The air conditioner allows the sensing of fine particles and ultrafine particles due to a plurality of particle sensors.

Abstract: An air outlet opening apparatus for air conditioners is provided. The air outlet opening apparatus includes a shutter for selectively opening and closing the air outlet formed on an air conditioner body. A pair of support plates is mounted beside the shutter to guide the elevation and lowering of the shutter. The air outlet opening apparatus further includes elevation means for selectively elevating and lowering the shutter. The elevation means includes a pair of elevation members positioned to be slid on the support plates, a drive motor for generating power to move the elevation members, and power transmission means for converting the rotating movement of the drive motor to the simultaneous linear movements of the elevation members.

Abstract: An air conditioner cabinet includes an air inlet and an air outlet. A U-shaped frame is mounted to the cabinet such that parallel vertical legs of the frame straddle the inlet. A pair of links are arranged for vertical sliding movement adjacent respective ones of the legs. Vertically spaced blades are mounted to the frame and extend across the inlet. The blades are mounted to the links such that vertical movement of the links causes the blades to pivot between inlet-opening and inlet-closing positions. The blades pivot through different respective angles whereby the inlet is opened by progressively greater amounts from the top to the bottom of the inlet.

Abstract: An air conditioner includes an air inlet and an air outlet. A door is movable vertically to open and close the air outlet. The door is guided for movement in guide slots which are configured to cause either a lower portion of the door, or the entire door, to move horizontally toward the air outlet during the closing operation. A spring may be provided to bias the closed door against the air outlet.
