Indoor unit of vertical air conditioner

Abstract

The invention provides an indoor unit of a vertical air conditioner. The indoor unit comprises a machine shell, a heat exchanger, a first cross flow fan and a second cross flow fan; the heat exchange is arranged in the machine shell; the first cross flow fan and the second cross flow fan are arranged up and down in the machine shell, vertically extend along an axis and are arranged collinearly; the machine shell comprises a framework, a bottom plate, a front upright post, a rear upright post, a left upright post, a right upright post and a shell; the framework is used for mounting the heat exchanger, the first cross flow fan and the second cross flow fan; the bottom plate is arranged below the framework and is used for supporting the indoor unit of the vertical air conditioner; the front upright post and the rear upright post respectively extends upwards from the front and rear sides of the bottom plate to the bottom end of the framework to support the framework; the left upright post and the right upright post respectively extend upwards from the left and right sides of the bottom plate to the top end of the framework to fix the framework; and the shell surrounds the outer side of the framework, the lower end of the shell extends to the edge of the bottom plate, a plurality of air outlets are formed in the front side of the shell, and an air inlet is formed in the rear side of the shell. The indoor unit of the vertical air conditioner, provided by the invention, is relatively low in fan air pressure loss and capable of saving more energy during operation and has various air supply modes, so that the user experience is improved.

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...

AI Technical Summary

Problems solved by technology

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 more serious, the energy consumption is larger, the output capacity of the fan is weakened, and the operating efficiency of the whole machine is greatly reduced.
