AI Technical Summary

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
