<p>The utility model relates to a transverse flow fan and air conditioner using transverse flow fan which is characterized in that a vane of the fan is provided with a ladder at a place near an axel center on a section plane perpendicular to a slewing axis, the thickest place of the vane is arranged at a place having two percent to thirty five percent distance from an advancing edge, and the thickness of the vane is gradually decreased from the thickest place to outside and to the periphery end. The shape can prevent the production of noise in the operation of air supply and improve the performance of air supply. Meanwhile, in the process of manufacturing the transverse flow fan, colophony can be used to form a vane, thereby raising the productivity effect. The utility model relates to a cross flow fan for indoor refrigerating or heating air conditioners. The utility model is characterized in that the sectional planes of blades of the utility model on a plane which is vertical to a rotary shaft is provided with steps; the positions of the blades with the biggest thickness are 2% to 35% away from the front edges of the blades, and the thickness of the blades are reduced gradually from the positions with the biggest thickness to the outer side and the outer circumference end. Because the utility model has the shape, the generation of noise during blowing operation can be avoided to increase blowing performance. Simultaneously, when the cross flow fan is manufactured, resin can be steadily used for forming the blade, and the productive efficiency can be increased.</p> |
