The invention claims the benefit of priority to Chinese patent invention No. 201010142896.9 titled “INDOOR UNIT OF AIR CONDITIONER”, filed with the State Intellectual Property Office of China on Apr. 2, 2010, the entire disclosures of which is incorporated herein by reference.
TECHNICAL FIELD OF THE INVENTIONThe invention relates to an indoor unit of air conditioner, and particularly, to an indoor unit of air conditioner having a distinct personalized effect.
BACKGROUND OF THE INVENTIONGenerally, an air conditioner is an apparatus which utilizes an air cooler, a heater or an air purifier to cool, warm or purify a room, such that an internal environment of the room is more comfortable. The air conditioner is provided with a ventilating device, an air cooling and heating device and an air purifier. The ventilating device makes the air forcibly circulated in the room, that is, absorbs air for the room, performs heat exchanging or purifies the air, and then discharges the air into the room. Improvements have been continually made to the air conditioner in the prior art. Generally, an indoor unit of air conditioner comprises a rear shell enclosing side portions and a rear portion of the air conditioner, and a panel body arranged in front of the air conditioner and closely connected to the rear shell. The rear shell and the panel body form an inner chamber of the air conditioner in which a heat exchanger, a control element and a fan component are provided. The panel body is usually fixedly connected to the rear shell in the manner of screw or clip. As air conditioner market becomes increasingly mature, consumers have more and more requirements on the air conditioner. Thus, manufacturers exhaustively improve the panel of the air conditioner. Accordingly, panels with color plates, decorative pictures or double-layer structures are developed. However, indoor units with such structures have following disadvantages: since the overall contour and the molding structure of the air conditioner are not changed at all, the lower portion of the indoor unit of air conditioner is still of a cuboid or polyhedron structure with edges and corners, the above improved solutions have no apparent effects on the improvements of aesthetics of the air conditioner.
SUMMARY OF THE INVENTIONAn purpose of the invention is to provide an indoor unit of air conditioner having a simple structure, being compatible with the overall environment indoors, and changing the decorative style of the appearance of the indoor unit of air conditioner.
In order to achieve the above purpose, the invention provides the following technical solutions.
An indoor unit of air conditioner comprising: a panel body enclosing side portions and a top portion of the air conditioner for installing a front panel, a rear shell enclosing a rear portion of the air conditioner, and the front panel arranged in the front of the air conditioner and closely connected to the panel body; the rear shell, the panel body and the front panel form an inner chamber of the air conditioner in which a heat exchanger, a control element and a fan component are provided; wherein, side surfaces of the indoor unit of air conditioner are of a U shape structure, and the front, the rear and the bottom surfaces of the lower portion of the indoor unit of air conditioner are formed by more than one curved surface.
To sum up, the invention has the following advantageous effects:
In the indoor unit of air conditioner according to the invention, since the side surfaces of the indoor unit of air conditioner are of a U shape structure, and the front, rear surfaces of the lower portion of the indoor unit of air conditioner comprise more than one curved surface, the overall contour of the indoor unit of air conditioner has a unique visual effect, and the indoor unit of air conditioner according to the invention becomes a new model with a distinct personalized feature. Thus, the invention plays an important role in improving the aesthetics of the air conditioner.
