Floor type air conditioner

[0026] The embodiments of the present invention will be described in detail below in conjunction with the drawings:

[0027] Such as Figure 2 to Figure 6 As shown, a floor-standing air conditioner includes a housing 1, in which a volute 4 and an evaporator 2 are provided, and a centrifugal fan 3 is provided in the volute 4; the evaporator 2 is upright and its The main body is perpendicular to the axis of the aforementioned centrifugal fan 3.

[0028] Wherein, the housing 1 is provided with an air inlet 5 and an air outlet 6. The air outlet 6 and the air inlet 5 are respectively located at the upper and lower parts of the housing 1, and the cooling channel between the air inlet 5 and the air outlet 6 is the evaporator 2. It is arranged on the cooling air duct and close to one end of the air inlet 5, the air outlet 6 is arranged directly in front of the casing 1, and the air inlet 5 is arranged on the left and right sides of the casing 1.

[0029] Between the evaporator 2 and the centrifugal blade 3, there is also a diversion ring 7 (the diversion ring 7 is fixed on the volute 4); the air inlet side of the diversion ring 7 is opposite to the evaporator 2, and the air outlet The side is opposite to the centrifugal fan 3. A rectangular frame 8 is provided on the air inlet side of the diversion ring 7 and a circular frame 9 is provided on the air outlet side. The center of the rectangular frame 8 and the circular frame 9 are overlapped, and the rectangular frame 8 and the circular frame 9 pass through the air outlet 10 is connected, the evaporator 2 is located in the rectangular frame 8, and the circular frame 9 extends into the centrifugal fan 3.

[0030] During the working process of the air conditioner, the air enters from the air inlet 5, and after the heat exchange through the evaporator 2, it directly enters the centrifugal fan 3. Since the main body of the evaporator 2 is perpendicular to the axis of the centrifugal fan 3, the air When flowing through the evaporator 2, the airflow passes through the heat exchange fins of the evaporator 2 in parallel, the airflow resistance is small, and the heat exchange effect is greatly improved.

[0031] The advantages of this embodiment are:

[0032] 1. Since the main body of the evaporator 2 is perpendicular to the axis of the centrifugal blade 3, when the air flows through the evaporator 2, the airflow passes through the heat exchange fins of the evaporator 2 in parallel, and the airflow resistance is small, and the heat exchange effect is greatly improved. ;

[0033] 2. After the guide ring 7 is set, almost all the airflow enters the centrifugal fan 3 after passing through the evaporator 2, avoiding the remaining part of the air from entering the centrifugal fan 3, improving the operation efficiency of the air conditioner and reducing energy waste;

[0034] 3. The air inlets 5 are arranged on the left and right sides of the casing 1 to reduce the influence of the air inlets 5 on the appearance of the casing 1.

[0035] The above are only specific embodiments of the present invention and do not limit the protection scope of the present invention; any replacement and improvement made on the basis of not violating the concept of the present invention shall fall within the protection scope of the present invention.
