Abstract

The invention provides an air conditioner indoor unit comprising a base housing and a cross flow fan, a heat exchanger, a front volute tongue and a rear volute tongue. Left fin gaps of the heat exchanger are smaller than right fin gaps of the heat exchanger; the front volute tongue comprises a front-left volute tongue and a front-right volute tongue, and the rear volute tongue comprises a rear-left volute tongue and a rear-right volute tongue; the front-left volute tongue and the rear-left volute tongue are respectively opposite to left fins of the heat exchanger, and the front-right volute tongue and the rear-right volute tongue are respectively opposite to right fins of the heat exchanger; S11> S12 allows L11< L12, and / or S21> S22 allows L21< L22. According to the air conditioner indoor unit, on the premise of guaranteeing the air volume, the problems that uneven air blowing and surging of the air conditioner indoor unit are optimized, and the noise of the air conditioner indoor unit is reduced. The invention further provides a volute tongue component.

Description

technical field [0001] The invention relates to the technical field of an air conditioner inner unit, and more specifically relates to an air conditioner indoor unit and a volute tongue assembly. Background technique [0002] For split-type air conditioners, the indoor unit generally adopts a fin-tube family heat exchanger. The fin gap in the heat exchanger is equal in theory, but in actual processing, the fins in the heat exchanger are from left to right. The fins on the left side of the heat exchanger are superimposed one by one (the left and right in this article refer to the left and right when the indoor unit is installed and facing the indoor unit), and finally the fin gap on the left side of the heat exchanger is larger than that on the right side of the heat exchanger (bell mouth) side) with small fin clearances. Since the smaller the fin spacing, the greater the airflow resistance and the smaller the air volume, so the air intake volume on the left side of the heat...
