Household packaged air conditioner of bottom air admission structure

Abstract

The invention discloses a household packaged air conditioner of a bottom air admission structure, which is characterized in that a wedge-type cavity base (2) is arranged at the bottom of an indoor unit body (1), large-bore bottom air inlets (3) are arranged on the left, on the right and in the rear of the base (2), the base (2) and the inside of the indoor unit body (1) are perpendicularly through to form a bottom air inlet channel, an induced-draft port of a centrifugal fan (6) is perpendicularly arranged downwards in the indoor unit body (1), and air is sucked by the centrifugal fan (6) rotatably driven by a perpendicular rotating shaft and flows into a heat exchanger (7) through an air channel. Inlet airflow enters the air conditioner from the bottom of the air conditioner and constantly flows along the same direction, airflow loss in change of flowing directions is decreased, flowing efficiency is improved, and flowing noise is reduced. In existing front air admission and lateral air admission, flowing directions are greatly changed, flowing loss is high, flowing efficiency is reduced, and airflow flowing noise is high.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a household cabinet air conditioner with a bottom air intake structure. Background technique [0002] At present, the air intake methods of household cabinet air conditioners (hereinafter referred to as air conditioners) mainly include forward wind, side air intake, and mixed front and side air intake. These three air intake modes are also traditional air-conditioning technologies. [0003] Forward wind refers to the air intake from the front of the air conditioner, the air flows horizontally into the body, and flows vertically upwards through the fan blades. Due to the large change of the airflow direction, a large flow loss is generated, which reduces the flow efficiency of the airflow, and because the air inlet is on the front side, the air intake noise is relatively large. [0004] Side air intake means that the air conditioner enters the air from the side, and the air fl...
