Description

Indoor unit of air conditioner Technical Field The present utility model relates to an indoor unit of an air conditioner, and more particularly, to an indoor unit of a vertical air conditioner. Background In general, an air conditioner has an electric device and various electric components, and these electric components are operated by a power supply, and therefore, a large number of connection wires are arranged in the air conditioner to electrically connect the power supply and the respective electric components. As described above, with the arrangement of a large number of electric components in an air conditioner, there is a possibility that problems such as short circuits and other electric leakage caused by unnecessary interference between the electric components may occur, and in order to prevent such problems, careful wiring design is required so that the electric wiring in the air conditioner does not cause interference between the components as much as possible. In particular, in the indoor unit of the vertical air conditioner divided into the upper casing and the lower casing, since a large number of connection wires are arranged in the electric components of the upper casing and the lower casing, when the indoor unit is arranged so that the blower fan can be opened and closed in the front to clean the blower fan provided in the upper casing, there is a possibility that the movement of the connection wires by the operation of the upper casing may cause disconnection. When such a connection wire is disconnected, the external power supply cannot smoothly supply power to the electrical components of the indoor unit, and thus, the indoor unit is stopped. Disclosure of utility model The utility model aims to provide an indoor unit of an air conditioner, which can stably arrange connection wires connected to an electric component of an upper shell from a main control box arranged on a lower shell. The present utility model also provides an indoor unit of an air conditioner, in which a roller bracket located directly below a hinge portion is used as a wire connection path between an upper case and a lower case when the hinge portion is used to perform a rotational operation of a blower fan assembly, so that an initial connection state can be maintained during the rotational operation of the blower fan assembly, and a length and a path of a connection wire are not changed. In order to achieve the above object, the present utility model is characterized in that a roller bracket located directly below a hinge portion is applied as a wire connection path between an upper case and a lower case when the rotation operation of a blower fan assembly is performed by the hinge portion, whereby an initial connection state is maintained at the time of the rotation operation of the blower fan assembly without changing the length and path of a connection wire, and the connection wire connected to an electric component of the upper case from a main control box provided to the lower case can be stably arranged. The indoor unit of an air conditioner may include an upper casing that sends out air having passed through a heat exchanger in a direction of a side discharge port, a lower casing that is provided at a lower side of the upper casing and has a lower casing body that forms a machine room space in which a main control box is provided, an air supply fan assembly in which a sub control box is provided at a front side thereof and is rotated by a hinge portion, a base portion that is provided at a lower side of the air supply fan assembly and has an inner space that forms an electric wire connection path, and a roller bracket that has an inner space that communicates with the base portion and is located directly below the hinge portion. In the connection wire connected between the main control box and the sub control box, a part of the connection wire connected to the sub control box may penetrate the wire connection path, and another part of the connection wire penetrating the wire connection path may be connected to the main control box through the roller bracket. According to an embodiment of the present utility model, the main control box may be connected to the connection wire including a display connection wire connected to the display portion of the upper case, a communication wire for communicating with the sub control box, and a high voltage connection wire. According to an embodiment of the present utility model, the sub control box may receive power from the main control box and supply the power to a driving part including the blower fan assembly. According to an embodiment of the present utility model, the sub control box may be disposed at a position on the front side of the indoor unit than the main control box when the indoor unit is viewed from the side. According to an embodiment of the present utility model, the base portion may include a flat plate penetrated by the wire connection passage. According
