Air duct structure and air conditioner indoor unit with same

Abstract

The invention provides an air duct structure and an air conditioner indoor unit with the same. The air duct structure is used for guiding airflow, the air duct structure comprises a first air duct, wherein a first fan blade assembly is arranged in the first air duct, and the first fan blade assembly is provided with a first hub; the first air duct communicates with a second air duct, a second fanblade assembly is arranged in the second air duct, and the second fan blade assembly is provided with a second hub; the first hub and the second hub are both in a circular truncated cone shape, the first hub is provided with a first large-diameter end, the second hub is provided with a second large-diameter end, and the first large-diameter end and the second large-diameter end are oppositely arranged, so that the airflow is blown out from the second air duct after being sucked in from the first air duct, or the airflow is blown out from the first air duct after being sucked in from the secondair duct; and a flow guide assembly is arranged between the first air duct and the second air duct so that the airflow in the first air duct can be guided into the second air duct or the airflow in the second air duct can be guided into the first air duct, and the problem that an air conditioner in the prior art is low in airflow energy utilization rate is solved.

Description

technical field [0001] The invention relates to the field of mechanical design, in particular to an air duct structure and an air conditioner indoor unit having the same. Background technique [0002] At present, the air conditioner has become an indispensable household appliance. The air conditioner has multiple air outlet modes to meet the needs of users. The air outlet of the air conditioner mainly depends on the air duct to guide the airflow. [0003] In the existing air-conditioning indoor unit, the air duct is provided with two air outlets to realize the cooling mode or the heating mode. One air outlet blows out, however, the above two air outlet methods will cause the two air outlets to blow out airflows with different temperatures at the same time, thereby reducing the energy utilization rate and the user's human comfort. Contents of the invention [0004] The main purpose of the present invention is to provide an air duct structure and an air-conditioning indoor ...
