Downward-air-out type air conditioner indoor unit, control method and air conditioner

Abstract

The invention provides a downward-air-out type air conditioner indoor unit, a control method and an air conditioner. The air conditioner indoor unit comprises an air deflector, and a rotating mechanism connected with the air deflector The air deflector can be pushed out or retracted into an air outlet; during the downward air-out process, the air deflector is driven to be pushed out and rotated toa fixed air-out position; when the air deflector is located at the fixed air-out position, a minimum distance M between the air deflector and the edge of the air outlet is larger than or equal to 10mm, and meanwhile, an included angle theta between an end edge tangent line of the air-out end of the air deflector and a horizontal direction is located between 10 degrees to 60 degrees; and the air-out end of the air deflector discharges air upwards. According to the downward-air-out type air conditioner indoor unit, the control method and the air conditioner provided by the invention, the wind resistance can be reduced, and a blown-out airflow can be maximally attached onto a wall surface of a ceiling to flow so as to form a wall attachment effect, so that the occurrence of the phenomenon that wind is directly blown to a human body is prevented to an extreme, cold air covers an indoor space to a maximum range, and the indoor comfort level is improved maximally.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an indoor unit of a down-flow air conditioner, a control method and an air conditioner. Background technique [0002] There are three main ways to prevent direct blowing in existing air conditioners: micro-hole air outlet, air deflector plate deflector, and upward air outlet. But above-mentioned three kinds of methods all have disadvantages: 1, micropore air outlet: prior art such as CN208108309U mainly utilizes a series of micropores on the air guide part to disperse the airflow, thereby reducing the turbulence of the airflow , to avoid blowing the gas directly to the user. However, this solution has large wind resistance, small air volume, severe temperature stratification, and poor comfort. 2. Air deflector shields the air outlet: in the prior art such as CN108489062A, when the air conditioner is in the anti-direct blowing mode, the air deflector is turn...

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the air conditioner in the prior art adopts the anti-direct blowing method, but the air resistance is large or the direct blowing phenomenon still occurs, or the air outlet from the bottom cannot be realized, so as to provide a bottom air outlet Air conditioner indoor unit, control method and air conditioner
