Abstract

The invention provides a cross-flow fan and an air conditioner with the same. The cross-flow fan according to the present invention includes: a cross-flow wind wheel, a rear wind guide volute and a volute connected volute. The wind surface and the wind guide surface include two side parts on both sides and a middle part in the middle in the length direction of the volute tongue parallel to the axial direction of the cross-flow wind rotor. The middle part is provided with an airflow combing structure, and the airflow combing structure has Protruding convex portion. The air conditioner according to the present invention includes the aforementioned cross-flow fan. According to the cross-flow fan of the present invention, the noise reduction effect is good, the cost is low, and it is easy to manufacture.

Description

technical field [0001] The invention relates to the field of refrigeration, more specifically, to a cross-flow fan and an air conditioner with the same. Background technique [0002] Cross-flow fans are often called cross-flow fans and linear-flow fans in the industry. see figure 1 and figure 2 , the cross-flow fan includes: the cross-flow wind wheel 3 and the air duct of the cross-flow fan, the air duct of the cross-flow fan is formed by the air inlet and outlet passages surrounded by the rear air guide volute 2 and the volute volute 1, as shown in the figure The range indicated by A is the air intake range of the cross-flow fan. combined reference figure 1 From the above air conditioner structure, it can be seen that the cross-flow fan is arranged in the air conditioner casing, and the air enters the interior of the air conditioner casing from the air inlet grille 5 of the air conditioner, and passes through the cross-flow fan blades and the air inlet grille. The eva...
