Worm tongue, air conditioner indoor unit and air conditioner

Abstract

The invention discloses a volute tongue, an air conditioner indoor unit and an air conditioner, wherein the volute tongue includes a first volute tongue plate and a second volute tongue plate; the first volute tongue plate is used to be arranged opposite to the wind wheel of the air conditioner; One end of the second volute tongue plate is connected with the first volute tongue plate, and the other end is used to extend towards the air outlet of the air conditioner; the side of the second volute tongue plate facing the air duct has a wind guide surface, and the wind guide surface is close to the end of the air outlet Extending horizontally or upwards; the wind guiding surface is provided with a suction structure so that the wind is blown out along the wall surface of the wind guiding surface. The technical solution of the present invention forms the Kangda airflow flowing along the air-guiding surface, avoiding the premature separation of the airflow from the air-guiding surface, so that the cold air is blown horizontally or upwards, preventing the cold air from blowing downwards and directly blowing people, improving the User comfort.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a volute tongue, an air conditioner indoor unit and an air conditioner. Background technique [0002] With the development of society, people have higher and higher requirements for the comfort of air conditioners. For example, when the air conditioner is cooling, it can not only achieve rapid cooling, but also prevent the cold wind from blowing directly to people. Rotate the wind deflector to make the cold air blow upwards, or open micro-holes on the wind deflector vanes to reduce the wind intensity, but the above methods are realized at the cost of air volume loss, which will affect the performance of the whole machine. [0003] The above content is only used to assist in understanding the technical solution of the present application, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] The main purpose of the presen...
