Description

Indoor unit for air conditioner

The present invention relates to an indoor unit of an air conditioner, and more particularly, to an indoor unit of an air conditioner in which a camera module is installed in a door assembly.

In the separate type air conditioner, an indoor unit is disposed indoors, an outdoor unit is disposed outdoors, and a refrigerant circulating between the indoor unit and the outdoor unit may cool, heat, or dehumidify indoor air.

The indoor unit of the separate type air conditioner includes a stand-type indoor unit installed upright on an indoor floor, a wall-mounted indoor unit installed on an indoor wall, and a ceiling-type indoor unit installed on an indoor ceiling according to an installation type.

In the conventional indoor unit of a separate type air conditioner, since the indoor fan is disposed inside the cabinet, there is a problem in that the air-conditioned air cannot be discharged to a long distance.

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.

In Korean Patent Laid-Open Publication No. 10-2017-0010293, an opening is formed in the cabinet of the 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, in Korean Patent Laid-Open Patent No. 10-2017-0010293 (hereinafter referred to as Prior Art 1), the door unit moves in the front-rear direction to open and close the opening, but since the door unit is located in front of the opened opening, it is discharged through the opening. There is a problem that obstructs the flow of air. That is, the opening of the opening by the door unit of the prior art 1 is not suitable for the flow of air over a long distance.

In Korea Patent Publication No. 10-2017-0010293 (hereinafter referred to as Prior Art 2), only the door is advanced and the opening is opened, and since the blowing fan is located inside the exterior panel, the air flowed by the blowing fan is inside the exterior panel. It causes a lot of flow loss in the long-distance flow of air by generating resistance with the structure.

China Registered Utility Model 203375535 U (hereinafter referred to as Prior Art 3) discloses a structure capable of rotating an axial fan within a predetermined angle range. However, in the axial fan of the prior art 3, since both sides of the axial fan are fixed to the rotating shaft, only a motion that is rotated based on the rotating shafts disposed on both sides can be implemented. Prior art 3 has a problem that the axial fan cannot be rotated in another direction not provided by the rotating shaft. That is, in the prior art 3, there was a problem in that the rotation shaft was rotatable only in the up-down direction or only in the left-right direction.

Korean Patent Application Laid-Open No. 10-2014-0079109 (hereinafter referred to as Prior Art 4) discloses an indoor unit in which a camera module is installed. However, since the camera module disclosed in Prior Art 4 is installed in a state protruding from the upper side of the case of the indoor unit, there is a possibility of damage due to external force during transportation of the product.

Korean Patent Registration 10-1191413 Korean Patent Publication No. 10-2017-0010293 China Registered Utility Model 203375535 U Korean Patent Publication 10-2014-0079109
