air conditioner indoor unit

Abstract

The invention provides an indoor unit of an air conditioner, which includes a casing, an air inlet, an air outlet, an evaporator and a cross-flow wind wheel. The back of the casing is provided with a left air inlet, a middle air inlet and a right air inlet side by side. The device covers the left air inlet, middle air inlet and right air inlet at the same time. The front of the casing is provided with left air outlet, middle air outlet and right air outlet. The left air outlet is connected with the left air inlet to form a left air duct and a middle air outlet It is connected with the middle air inlet to form a middle air duct, the right air outlet is connected with the right air inlet to form a right air duct, and the left air duct, the middle air duct and the right air duct are independent of each other. The air conditioner indoor unit adopts three independent air ducts to enhance the effect of diversion, air intake and air outlet, and improve the air supply capacity of the air conditioner indoor unit; and the three air outlets are arranged side by side on the left, middle and right, which can realize The 180-degree air supply angle range increases the air supply area to meet people's use requirements and improve the comfort of the indoor unit of the air conditioner.

Description

technical field [0001] The invention belongs to the technical field of air conditioner manufacturing, and in particular relates to an indoor unit of an air conditioner. Background technique [0002] In a traditional indoor unit of an air conditioner, the centrifugal fan arranged at the bottom and the volute outside the centrifugal fan are generally used to realize the air inlet and outlet from the lower parts on both sides and the bottom of the front panel, and the air from the upper parts on both sides and the top of the front. Basically, the flow direction of the airflow is along the length of the indoor unit of the air conditioner, and because there are other components in the indoor unit of the air conditioner, the airflow from the air inlet to the air outlet needs to be reversed several times inside the indoor unit of the air conditioner. As a result, the flow resistance of the airflow during the flow process increases, and the energy loss increases accordingly, which i...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an air conditioner, aiming to solve the problem of poor air inlet and outlet effects and poor air outlet effects caused by the small air supply angle and small air supply area of ​​single and double cross-flow fan air conditioners in the prior art. The loss of air-conditioning comfort and poor air supply capacity caused by the limitation of the wind range cannot meet the needs of people
