Air duct component, indoor unit and air conditioner

Abstract

The invention provides an air duct component, an indoor unit and an air conditioner; the air duct component is suitable for electrical equipment, and the air duct component comprises: a fan mounting cavity used for mounting a fan; the air inlet duct that communicates with the fan mounting cavity and is used for air inlet; the air outlet duct that is communicated with the fan mounting cavity, is positioned on one side, close to or far away from the supporting base surface of the electrical equipment, of the fan mounting cavity, and is used for air outlet. The air duct component comprises a first preset plane A perpendicular to a supporting base plane of the electrical equipment, a first preset included angle is formed between the extending direction of the air outlet duct and the first preset plane A, and the first preset included angle is an acute angle. According to the air duct component, the problem that the air supply speed and the air supply distance of an air conditioner provided with a centrifugal fan in the prior art are affected due to the fact that the rotating direction of air outlet airflow is large is solved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air duct component, an indoor unit and an air conditioner. Background technique [0002] At present, cabinet air conditioners are mainly divided into cross-flow fan system and centrifugal fan system. The centrifugal fan system generally installs a centrifugal fan in the middle of the casing or combines multiple centrifugal fans, and adopts bottom side air inlet and upper air outlet. The centrifugal fan is usually arranged up and down, and the wind entering the casing needs to be accelerated by the centrifugal fan first, then exchange heat with the heat exchanger inside the casing, and finally flow out from the air outlet above the casing. [0003] Cabinet air conditioners in the prior art have at least the following problems: [0004] (1) The air outlet speed of the centrifugal fan is not uniform enough, the heat exchange efficiency is low, and the demand for the air...

AI Technical Summary

Problems solved by technology

[0009] The main purpose of the present invention is to provide an air duct component, an indoor unit, and an air conditioner, so as to solve the problems of the air conditioner equipped with a centrifugal fan in the prior art, which affects the air speed and air flow rate due to the large turning of the air outlet airflow. problem of distance
