Problems solved by technology

[0005] However, such a cross-flow fan according to the prior art generates vortices in the discharged air flow due to the rotation of the blades, which may cause the cross-flow fan to generate noise and vibration in an indoor space, thereby causing inconvenience to users.
Moreover, the vortex will reduce the efficiency of introducing and discharging air, resulting in a decrease in the overall performance of the air conditioner

Abstract

A cross flow fan and an air conditioner including the cross flow fan, where the cross flow fan includes a fixing member (120), and a plurality of blades (110) fixed to an upper surface of the fixing member and spaced apart from each other in a circumferential direction. One or more of the blades (110) include a protrusion (113) protruding in a downward direction from a surface of the blade.

Description

technical field [0001] The invention relates to a cross-flow fan and an air conditioner. Background technique [0002] Generally speaking, an air conditioner is a device that cools or heats an indoor space. An air conditioner includes a compressor that compresses refrigerant, a condenser that condenses refrigerant discharged from the compressor, an expander that expands refrigerant passing through the condenser, and an evaporator that evaporates refrigerant expanded in the expander. [0003] A condenser and an evaporator in an air conditioner are installed in an outdoor unit or an indoor unit as a heat exchanger for exchanging heat between a refrigerant and outside air. When the indoor unit is installed with the heat exchanger, the indoor unit may include a cross-flow fan on one side thereof. [0004] A cross-flow fan includes a circular plate and a plurality of blades provided on the circular plate. Cross-flow fans are used to discharge radially introduced air. That is,...
