Description

Air duct assembly and air conditioner indoor unit with same Technical Field The utility model relates to the technical field of air conditioners, in particular to an air duct assembly and an air conditioner indoor unit with the same. Background With the improvement of living standard, people pay more attention to the air quality of living and office environments. Among them, an air conditioner is a commonly used air treatment device. The indoor unit of the air conditioner in the related art comprises a fan and an air duct framework, and the air duct framework is usually formed by injection molding. In order to ensure the air output of the indoor unit of the air conditioner, the gap between the fan and the air duct board of the air duct skeleton is usually small (the gap between the fan and the air duct board is usually 6mm to 7.5 mm). But the air duct plate structure intensity of the air duct skeleton in the related art is lower, so that the air duct plate is easy to deform, the gap between the fan and the air duct plate of the air duct skeleton is further reduced, larger airflow noise can be emitted, and when the deformation of the air duct plate is larger, the fan can be ground, so that the fan is damaged sufficiently. Disclosure of utility model The present utility model has been made in view of the above-mentioned problems, and an air duct assembly and an air conditioner indoor unit having the same, which overcome or at least partially solve the above-mentioned problems. The utility model aims to solve the problem of lower strength of the air duct plate structure of the air duct framework in the related technology, so as to realize the purposes of reducing the air flow noise emitted by the fan during operation and avoiding the occurrence of fan noise. In particular, the present utility model provides an air duct assembly. The air duct assembly of the present utility model includes an air duct skeleton including an air duct plate for defining an air duct; The support piece is arranged on the leeward side of the air duct plate, a closed accommodating cavity is formed in the support piece, or the support piece and the air duct plate define a closed accommodating cavity, and gas is filled in the accommodating cavity. In some embodiments, the support member includes a first side plate having one end connected to the duct plate and extending in a width direction of the duct plate, the width direction being perpendicular to a flow direction of the air flow, a second side plate having one end connected to the duct plate and disposed in spaced relation to the first side plate, a third side plate connected between the first side plate and the second side plate, the third side plate being disposed in spaced relation to the duct plate, the receiving cavity being disposed between the third side plate and the duct plate and between the first side plate and the second side plate.
