Problems solved by technology

[0013] First, when the air is introduced through the suction port located on the side of the front case and exhausted through the front and side of the upper part of the front case, it will generate a lot of noise
[0014] Second, when cleaning or changing the air filter 9, you need to open the left and right suction grids 7, 8 and remove the air filter 9 from the left and right suction grids 7 and 8. If you often open the left and right suction grids, Then the connecting parts of the left and right suction grids 7 and 8 are easily damaged
[0015] Third, when the air conditioner is not running, since only the side air outlets 4b and 4c can be closed by the left and right blades 14 and 16, dust may enter through the suction grilles 7 and 8 and the suction ports 4d and 4e, and in The air suction grids 7 and 8 and the blades 14 and 16 are arranged on both sides of the front housing 4 to complicate the structure of the air conditioner, and the separate production of the air suction grids 7 and 8 and the blades 14 and 16 increases the cost
[0016] Fourth, visually, at the rear of the upper air outlet 4a, the upper part of the heat exchanger 30 detracts from the overall appearance of the air conditioner, and the opening / closing panel 12 and the front / rear moving panel 12 make the structure of the front case It becomes complicated, and the color of the front case 4 is not easy to change

Embodiment Construction

[0058] Reference will now be made in detail to the preferred embodiments of the invention, which are shown in the accompanying drawings. In describing the embodiments, the same components have the same names and reference numerals, and repeated descriptions of the same components will be omitted.

[0059] refer to Figures 4 to 11 , the indoor unit of the air conditioner includes a casing with air inlets 70a, 70b and 70c and air outlets 72a, 72b and 72c formed thereon, and a fan 80 located in the lower space inside the casing, and a fan 80 located on the fan 80 and A heat exchanger 90 for exchanging heat by the forced flow air caused by the fan 80 .

[0060] The case includes a base 50 and a rear case 60 and a front case 70 installed at an upper surface of the base 50 . The rear case 60 has an open front and a trapezoidal horizontal section whose width gradually increases as the section extends forward, thereby improving space utilization in a house when the indoor unit is i...
