Abstract

The cross-flow fan comprises a shell, a volute, a cross-flow impeller and a volute tongue structure, an installation space is formed in the shell, the volute is arranged in the installation space, the cross-flow impeller is rotationally installed in an air inlet duct, the two adjacent sides of the volute tongue structure are the flow guide side and the drainage side respectively, and the flow guide side and the drainage side are communicated with the volute tongue structure. The flow guide side is used for being arranged opposite to a cross-flow impeller so as to define a backflow channel, the drainage side is used for being arranged towards an air outlet channel, the volute tongue structure defines a jet flow channel, one end of the jet flow channel penetrates through the drainage side so as to form a jet flow inlet, and the other end of the jet flow channel penetrates through the flow guide side so as to form a jet flow outlet. The jet flow channel is provided with a speed reduction structure used for reducing the flow speed of jet flow in the jet flow channel. While the eccentric vortex control effect is guaranteed, the impact effect of jet flow on the impeller is remarkably reduced, interference noise of the cross-flow fan is reduced, and the quality of the cross-flow fan is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a cross-flow fan and an air conditioner. Background technique [0002] The cross-flow fan has the advantages of small radial size, low speed, low noise, and uniform air outlet. Its axial length can be arbitrarily lengthened without affecting the gas flow state. It is widely used in flat and long air conditioners, cabinets, tower fans, etc. in home appliances. At present, facing the problem of insufficient static pressure lifting capacity of the cross-flow fan, generally the airflow at the air outlet is directly introduced into the cross-flow impeller through the drainage channel, which can improve the strength of the eccentric vortex in the middle of the cross-flow impeller and increase the static pressure coefficient of the fan. However, the direct impact of the airflow in the drainage channel on the cross-flow impeller will cause a large impact noise, and the quality ...
