Problems solved by technology

[0007] However, in the conventional axial flow fan, since the contour line of the rear edge of the blade is located in the air introduction direction from the side peripheral end of the air inflow surface of the bell mouth, the flow out from the rear edge of the blade The air will collide with the outer peripheral end of the air inflow surface of the bell mouth, thus, a vortex will be generated, and thus, the noise of the blower will increase

Abstract

An outdoor unit for an air conditioner has an axial-flow fan and a bell mouth. The axial-flow fan is constructed by arranging blades at predetermined intervals along the outer periphery of a hub, each of the blades being formed such that the outline of its rear edge relative to the rotational direction is recessed toward its front edge. The bell mouth is provided on the side of air blow by the axial-flow fan. An axial-flow blower is provided in the outdoor unit. The bell mouth and the axial-flow fan are arranged in the axial-flow blower such that a ratio X / L is in the range of 0.2-0.8 with X being the distance between that portion of the blade's rear edge outline that is most deeply inwardly recessed in the rotating direction and an air outflow surface of the bell mouth, L being the axial length of bell mouth.

Description

[0001] This application is a divisional application of an invention patent application with an international application date of March 29, 2004, a national application number of 200480008503.8, an international application number of PCT / JP2004 / 004426, and an invention title of "outdoor unit for air conditioner". technical field [0002] The invention relates to an outdoor unit of an air conditioner, in particular to an outdoor unit equipped with an axial flow blower capable of suppressing the noise of the blower. Background technique [0003] In the conventional art, an outdoor unit of an air conditioner is constructed such that a bell mouth is connected to a discharge port, and an axial flow blower is arranged in the bell mouth along the air inflow direction, and the axial flow blower has a multi- An axial fan with two blades arranged at predetermined intervals along the outer peripheral surface of a rotating hub. [0004] In the axial flow fan of the above outdoor unit, wh...
