摘要： An airfoil blade for a fan impeller, includes one blade surface portion formed by extrusion molding. A plurality of ribs are integrally formed with the one blade surface portion to extend upwardlyf rom it in generally a vertical direction and having heights as will provide a curve line for the other curved blade surface portion when end faces of the ribs are connected to each other. A sheet material is applied onto the ribs along their end faces to provide the other curved blade surface portion so as to form a blade configuration of the airfoil blade having a leading edge and a trailing edge and including hollow portions in it.

摘要： A blower includes a plurality of rotatable impeller vanes operable to impel air. The impeller vanes create an air pressure differential thereacross when rotated, and each of the impeller vanes has a porous central portion made of sintered resin material. The porous central portion has a plurality of pores therein which permit a portion of air to pass through the porous central portion from a relatively high air pressure side to a relatively low air pressure side of the impeller vanes. Each of the impeller vanes also has a non-porous portion surrounding the porous central portion. The non-porous portion is made of a solid resin material which prevents air from passing therethrough.

摘要： An impeller of a multiblade blower having at least two circular end plates or partition plates spaced apart from each other, and a plurality of blades disposed between the peripheral portions of the partition plates. Each of the blades is formed with a cylindrical portion having a uniform cross-sectional area, at the outer peripheral end thereof on the outer peripheral side of the impeller. The cylindrical portion has a diameter which is larger than the thickness of the blade at the outer peripheral end thereof so that the cylindrical portion is projected from both front and rear surfaces of the blade at the outer peripheral end of the latter.
摘要翻译：具有至少两个彼此间隔开的圆形端板或分隔板的多叶片鼓风机的叶轮，以及设置在隔板的周边部分之间的多个叶片。每个叶片在叶轮的外周侧的外周端形成有具有均匀横截面面积的圆筒部。圆筒部的直径比叶片的外周端部的厚度大，因此圆筒部从刀片的前后表面在后端的外周端突出。

摘要： The disclosure is directed to a mixed flow impeller with a low noise, to be used for a blower of an air conditioner or the like. The mixed flow impeller of the present invention is characterized in three points, i.e., thin thickness blade member increased in its thickness only at its leading edge, a plate-like triangular protrusion provided at an outer peripheral portion of the leading edge, and blade curvature line having its maximum curvature position deviated toward the trailing edge side through employment of a cubic curve. Since each of the above features may be caused to function independently, noise reduction is possible even if it is executed singly, but the maximum effect is available when the are effected in combination.
摘要翻译：本发明涉及一种低噪音的混流式叶轮，用于空调机等的鼓风机。本发明的混合流动叶轮的特征在于三个点，即厚度薄的叶片构件仅在其前缘处增加其厚度，设置在前缘的外周部分处的板状三角形突起，并且叶片曲率其最大曲率位置通过使用三次曲线向后缘侧偏离。由于可以使上述每个功能独立地起作用，所以即使单独执行也可以降低噪声，但是当组合实现时，最大效果是可用的。
