Window-type air conditioner

Abstract

A window air-conditioner consists of evaporator and indoor fan in and compressor, condenser, outdoor fan and motor in outdoor side; arranging scroll between indoor side and outdoor side and forming said scroll by top scroll and bottom scroll; setting back plate at back end of scroll; setting circular scroll line and air inlet on front end of back plate; setting air outlet on top end of back plate and forming multiple ring form concave hole along internal periphery of said scroll line.

Description

technical field [0001] The invention relates to a window type air conditioner, in particular to a window type air conditioner capable of changing the air volume and direction to reduce noise. Background technique [0002] An air conditioner is a device that makes its internal refrigerant undergo a refrigeration or heating cycle consisting of a compression process, a condensation process, an expansion process, and an evaporation process. It is usually divided into domestic air conditioners and commercial air conditioners. It can be divided into split type air conditioner and window type air conditioner. Fig. 1 is a longitudinal structural sectional view of a window air conditioner in the prior art. Fig. 2 is an exploded perspective view of part of the structure of the window air conditioner in Fig. 1 . As shown in Figures 1 to 2, this prior art window air conditioner is divided into an indoor side and an outdoor side, and mainly includes a casing 1, a chassis 2, a compresso...

AI Technical Summary

Problems solved by technology

But there is following problem in this window type air conditioner of prior art: because the air outlet dynamic pressure of indoor fan 5 is too large, when the airflow that it discharges impinges on the front end face of back plate 15, will form comparatively locally. Large eddy currents, resulting in noise, which will undoubtedly cause dissatisfaction among consumers
