Indoor unit of air conditioner

Abstract

The invention provides an indoor unit of an air conditioner. The indoor unit comprises a housing, an air inlet, an air outlet, an evaporator and a cross-flow wind wheel assembly. The left, middle and right of the back of the housing are provided with a left air inlet, a middle air inlet and a right air inlet in parallel. The evaporator covers all of the left air inlet, the middle air inlet and the right air inlet. The front of the housing is provided with a left air outlet, a middle air outlet and a right air outlet. The left air outlet and the left air inlet are communicated with each other to form a left duct; the middle air outlet and the middle air inlet are communicated with each other to form a middle duct; the right air outlet and the right air inlet are communicated with each other to form a right duct; the left duct, the middle duct and the right duct are mutually independent. The indoor unit employs the three independent ducts, flow guidance effect, air incoming effect and air outgoing effect are enhanced, and air supply capacity of the indoor unit is enhanced. The three air outlets are parallelly arranged on the left, in the middle and on the right, 180-degree air supply angular range can be achieved, air supply area is enlarged, the requirements of people for use are met, and the indoor unit is more comfortable for people to use.

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...

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
