Embodiment Construction

[0030] Such as Figure 1-3 As shown, the present invention provides an air conditioner indoor unit, which includes a cross-flow fan blade 3 and an air duct, the air duct has an air duct outlet 11, and the air duct outlet 11 includes an upper guide wall 1 and a lower guide wall 2;

[0031] On the cross-section of the cross-flow vane 3:

[0032] The cross-flow vane 3 has a vane center 31, defines the inner upper edge of the upper guide wall 1 as the first end 12, the inner lower edge of the lower guide wall 2 as the second end 21, and the lower guide wall 1 is defined as the first end 12. The inner lower edge of the flow guide wall 2 is the shortest position between the lower flow guide wall 2 and the upper flow guide wall 1;

[0033] And there is a connection between the blade center 31 and the first end 12 to form a first connection line, and a connection between the blade center 31 and the second end 21 to form a second connection line, and the first A first angle a is for...

Abstract

The invention provides an air conditioner indoor unit and an air conditioner. The air conditioner indoor unit comprises a cross-flow fan and an air flue; the air flue is provided with an air flue outlet; the air flue outlet comprises an upper flow guide wall and a lower flow guide wall; on the cross section of the cross-flow fan, the cross-flow fan is provided with a fan center, the upper edge of the inner side of the upper flow guide wall is defined as a first end, and the lower edge of the inner side of the lower flow guide wall is defined as a second end; the fan center and the first end are connected through a first connecting line, the fan center and the second end are connected through a second connecting line, and a first included angle alpha is formed between the first connecting line and the second connecting line; the smallest interval between the air flue and the fan center is defined to be located at the intersection of the air flue; and the fan center and the intersection are connected through a third connecting line, the first end and the second end are connected through a fourth connecting line, a second included angle beta is formed between the third connecting line and the fourth connecting line, and a / b is 0.35-0.58. By means of the air conditioner indoor unit and the air conditioner, the cross-flow fan can be arranged at a proper position in the air flue, the noise of the indoor unit is reduced to the greatest extent, and the operating performance of the air conditioner is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner indoor unit and an air conditioner. Background technique [0002] At present, the existing vertical air-conditioning cabinets mainly focus on technical improvement and innovation in terms of cooling and heating performance, but ignore the effects of air volume and noise of the air-conditioning, resulting in frequent noises during the operation of the vertical air-conditioning cabinets. Large, poor sound quality of the air conditioner, affecting the comfort of the indoor environment. [0003] Since the vertical air conditioner cabinet in the prior art has technical problems such as high noise during operation, the present invention researches and designs an air conditioner indoor unit and an air conditioner. Contents of the invention [0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect ...
