Abstract

The invention provides a vertical air conditioner indoor unit. The indoor unit comprises a machine shell, a plurality of air outlets are vertically formed in a front panel, and the rear side of the machine shell is provided with an air inlet; a heat exchanger is arranged in the machine shell, a first cross flow fan and a second cross flow fan are vertically arranged in the machine shell, the axes vertically extend, the first cross flow fan and the second cross flow fan are collinear, and therefore the air is promoted to enter the machine shell via the air inlet and is subject to heat exchange with the heat exchanger to be blown out of the corresponding air outlet; an air flue assembly is erected on the circumferential outer sides of the first cross flow fan and the second cross flow fan so as to enable air to be led to the air outlets forwards from the heat exchanger, an air flue partition part is mounted on the air flue assembly and is located between the first cross flow fan and the second cross flow fan, space limited by the air flue assembly is partitioned into an upper portion and the lower portion, the first cross flow fan and the second cross flow fan are contained in the upper portion and the lower portion correspondingly, and the air flue partition part is provided with two bearings matched with a rotating shaft of the first cross flow fan and a rotating shaft of the second cross flow fan correspondingly. According to the indoor unit, the air flue assembly can be simplified, and the influence of the air flue assembly on the heat exchange efficiency of the heat exchanger can be reduced.

Description

technical field

[0001] The invention relates to the technical field of air conditioning, in particular to a vertical air conditioner indoor unit. Background technique

[0002] At present, traditional vertical air conditioner indoor units mostly use a centrifugal fan as a power source to drive air flow. The centrifugal fan and the heat exchanger are arranged in the casing of the indoor unit along the vertical direction, the air inlet is arranged at the lower part of the casing, and is opposite to the centrifugal fan, and the air outlet is arranged at the upper front side of the casing, and is connected with the heat exchange device. relatively. The air enters the casing through the air inlet at the lower part, flows through the air channel of the centrifugal fan and the heat exchanger in turn, and then is sent out from the air outlet at the upper part. It can be seen that the distance of the airflow from the air inlet to the air outlet is longer, the wind pressure loss is m...
