Window type air conditioner

Abstract

The invention provides a window type air conditioner. The air conditioner comprises a shell, a cross-flow wind wheel and a volute air duct; the shell is provided with an exhaust outlet and an air return port, and the air return port is formed in the lower side of the exhaust outlet; the cross-flow wind wheel is located in the shell; and the volute air duct is located in the shell and communicateswith the exhaust outlet and the air return port, wherein the volute air duct comprises a volute part and a volute tongue part, the intersection line formed by the intersection of the inner surface ofthe volute part and the middle section perpendicular to the axis of the cross-flow wind wheel is a molded line of the volute part, a first intersection point is formed between the vertical tangent line of the front end point of the outer circumference of the cross-flow wind wheel and the molded line, and the first intersection point is located on the upper side of the cross-flow wind wheel. The window type air conditioner is low in noise and long in air supply distance, and the whole airflow boosting region at the downstream position of the cross-flow wind wheel is covered by the volute part,so that the air flow is guided by the volute part, and is discharged after straightening, the problem of turbulence noise or high noise at the position of the exhaust outlet is solved, the mute performance of a product is improved, the wind guiding efficiency of the cross-flow wind wheel can be improved by the design, the air outlet quantity and the heat exchange efficiency of the window type airconditioner are improved comprehensively, and the energy efficiency of the product is guaranteed.
