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 may be provided with an air discharge portion at a front portion, an air conditioning unit such as a heat exchanger or a filter capable of changing the temperature, humidity, or cleanliness of air, and an air blowing device for causing air to flow. An air conditioner used in a home is mainly a split type air conditioner in which an indoor heat exchanger and an indoor fan are installed in an indoor unit, an outdoor heat exchanger, an outdoor fan, a compressor, and the like are installed in an outdoor unit, and the indoor unit and the outdoor unit are separated from each other by a refrigerant pipe, and the split type air conditioner can be divided into a wall-mounted type and a vertical type according to the form of the indoor unit. The upright air conditioner may include a fan for generating an air flow, a shroud provided at a suction side of the fan to guide suction of air, and a discharge blade for switching the air flow of the air discharged through the air discharge part. In the case of the conventional air conditioner, the air discharge portion is provided on the front surface of the indoor unit main body, and therefore, the air flow can be directed forward by the air discharged from the front surface of the indoor unit. Recently, however, the demand for air flow from the front of the air discharged from the front of the indoor unit to the side of the air discharged from the side of the indoor unit has been increasing. In order to form the side-directed airflow, there is a problem in that an additional side discharge port needs to be formed on the indoor unit side, and a side vane for opening and closing the side discharge port needs to be additionally provided. In addition, when there are additional discharge ports and vanes, there is a problem that not only is the flow rate of air discharged from the main discharge port reduced, but also the resistance of the discharge flow is large due to the complexity of the air flow path. Patent document 1 Korean patent laid-open publication No. 10-1403003 (2014.05.27) Disclosure of utility model The utility model aims to provide an indoor unit of an air conditioner, which can form forward-oriented airflow and side-oriented airflow through one air outlet. An object of the present utility model is to provide an indoor unit of an air conditioner having a vane capable of easily switching a flow direction of air discharged through an air discharge port. The utility model aims to provide an indoor unit of an air conditioner, which is provided with hidden blades capable of keeping a hidden state and not exposing from the outside. The utility model aims to provide an indoor unit of an air conditioner with a blade which can be stably driven without shaking. An indoor unit of an air conditioner according to an embodiment of the present utility model includes a casing that forms a suction port through which air is sucked, a heat exchanger provided inside the casing, a blower module unit connected to the casing and configured to discharge air passing through the heat exchanger toward a side discharge port, and a hidden vane module configured to switch a flow direction of the air discharged through the side discharge port. The hidden blade module may include a blade housing forming an inner space, a hidden blade capable of reciprocating inside the blade housing, and a blade cover coupled with the blade housing to cover the hidden blade. When the hidden vane moves, a part of the hidden vane may be exposed to the outside of the vane housing, and may be disposed adjacent to the side discharge port. The air discharged through the side discharge port may collide with a portion of the hidden vane, whereby the direction of the air flow may be switched. The indoor unit may further include a vane driving part provided to the hidden vane to provide a driving force for the reciprocating movement of the hidden vane. The blade driving part may include a driving motor, a pinion gear coupled to a motor shaft of the driving motor, and a rack gear provided to the hidden blade to be coupled to the pinion gear. The indoor unit may further include a motor bracket coupled to an inner side of the hidden blade to accommodate the driving motor. A guide rail guide may be formed at the motor bracket, and coupled to an inner side of the hidden blade, to guide the reciprocating movement of the hidden blade. The indoor unit may further include a plurality of rollers coupled to an inner side of the hidden vane to support the hidden vane. The vertical gravity line G of the hidden vane may be disposed between a plurality of the rollers. The indoor unit may further include a guide gear coupled between the vane housing and the hidden vane to guide the reciprocating movement of
