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 purification degree of air, and an air blowing device for causing air to flow. A household air conditioner is mainly used in which an indoor heat exchanger and an indoor blower are provided in an indoor unit, an outdoor heat exchanger, an outdoor blower, a compressor, etc. are provided in an outdoor unit, and the indoor units of the separate air conditioner are divided into a wall-mounted type and a vertical type by the form by connecting the indoor units and the outdoor units with each other with a refrigerant pipe. The frequency of use of indoor units of air conditioners realized in a vertical manner tends to increase rapidly due to the rise of standard of living and abnormal air temperature phenomena of modern people. With this demand, diseases of respiratory organ related systems caused by odor and dirt inside an indoor unit of an air conditioner are increasing, and problems of cleaning the indoor unit are also increasing year by year, so it is very important to keep the indoor unit clean by frequent cleaning. In particular, it is important to keep the heat exchanger, the blower fan, and the like inside the indoor unit through which the sucked air flows clean. However, since the main components of the indoor unit of the upright air conditioner are fastened to the inside of the casing by the fastening mechanism, the indoor unit is difficult to manage and the cleaning state is poor, and thus the pollution of the indoor unit is accelerated, and finally, the diseases of the respiratory organ related system caused by malodor and bacterial reproduction are caused. In addition, in the indoor unit of the conventional upright air conditioner, the height of the product is far greater than the area of the bottom surface of the product, and the center of gravity is located in the upper casing due to the loaded component, so that only a structure that is easy to turn over is provided. Disclosure of utility model The present utility model is aimed at providing a cleaning operation and management easiness by easily performing an opening and closing operation of a blower fan unit by having a hinge part capable of opening and closing the blower fan unit from a shield case and a roller bracket including a rotating roller which rolls along a horizontal base on an outlet side of the shield case and is capable of supporting a load of the blower fan unit, and preventing an indoor unit of an air conditioner from overturning by stably performing a supporting operation of the blower fan unit. Further, the present utility model is directed to an air conditioner including a locking portion for restricting rolling of a rotary roller provided at a maximum open position of an air blowing fan assembly, whereby the movement of the center of gravity to the outside of an indoor unit is blocked by maintaining a fixed state of the air blowing fan assembly, and thus the indoor unit of the air conditioner can be prevented from falling down by effectively maintaining the balance of the indoor unit of the air conditioner. The present utility model also has an object to enable easy opening and closing of the blower fan assembly with respect to the shroud housing by applying a key-type latch assembly to the shroud housing and the blower fan assembly. In order to achieve the above object, in the indoor unit of an air conditioner according to the embodiment of the present utility model, a hinge part may be provided between the blower fan assembly and the shroud housing to open and close the blower fan assembly, and a roller bracket including a rotating roller integrally coupled to a lower end of the blower fan assembly and rolling along a top surface part of the horizontal base when the blower fan assembly is opened by the hinge part may be provided. Therefore, the opening and closing operation of the blower fan assembly can be easily performed, whereby the cleaning work and the management are easy, and the supporting operation of the blower fan assembly can be stably performed. In the indoor unit of the air conditioner according to the embodiment of the present utility model, a latch assembly that is inserted into and operates on the outlet side of the shroud case may be provided, and a locking groove portion into which the latch of the latch assembly is inserted and restrained may be provided on the upper side of the blower module portion. Therefore, the blower fan assembly can be easily opened and closed with respect to the shroud housing. According to an embodiment of the present utility model, the air blowing fan assembly may further i
