Description

Air Conditioner {Air Conditioner}

The present invention relates to an air conditioner, and more particularly, to an air conditioner including a discharge grill that moves forward and backward.

An air conditioner refers to a device that sucks air and purifies, cools, heats, humidifies, or dehumidifies the inhaled air by removing dust.

For example, in a separate type air conditioner, an indoor unit is arranged indoors, an outdoor unit is arranged outdoors, and the indoor air is cooled, heated, or dehumidified through a refrigerant circulating between the indoor unit and the outdoor unit, or indoors through a humidification module or filter. You can humidify or purify indoor air.

The air conditioner may include a circulator to direct the conditioned air to a remote location. For example, in Korean Patent Registration No. 10-1191413, a circulator for flowing air around an indoor unit to a long distance is provided.

However, although the air circulator described in Korean Patent Registration No. 10-1191413 is installed in the indoor unit, it cannot directly flow the conditioned air, and provides a function of flowing the indoor air above the indoor unit to a long distance.

Since the air circulator cannot directly flow the conditioned air, the conditioned air cannot be intensively supplied to the target region, and thus there is a problem in that the target region in which the temperature imbalance occurs cannot be selectively air-conditioned.

Meanwhile, in Korean Patent Laid-Open Publication No. 10-2017-0010293, an opening is formed in a cabinet of an indoor unit, and a door unit for opening and closing the opening is disposed. The door unit of Korean Patent Laid-Open Publication No. 10-2017-0010293 is movable in the forward and backward directions, and blocks the opening when the indoor unit is not in operation, and moves the door unit forward to open the opening when the indoor unit is in operation.

However, Korean Patent Laid-Open Patent No. 10-2017-0010293 discloses that the door unit moves in the front-rear direction to open and close the opening, but since the door unit is positioned in front of the opened opening, there is a problem in obstructing the flow of air discharged through the opening. have. That is, the opening of the opening by the door unit of Korean Patent Application Laid-Open No. 10-2017-0010293 is not suitable for flowing air over a long distance.

In addition, in Korea Patent Publication No. 10-2017-0010293, only the door advances to open the opening, and since the blowing fan is located inside the exterior panel, the air flowed by the blowing fan generates resistance with the structure inside the exterior panel. This causes a lot of flow loss to flow the air over a long distance.
