Document Type and Number:
WIPO Patent Application WO/2019/012578
Kind Code:
A1
Abstract:
An indoor unit for an air conditioner is provided with a cross flow fan. An impeller of the cross flow fan has a plurality of blades each having a first end part and second end part as end parts along the direction of a rotary shaft, and a support panel that supports the first end parts of each of the plurality of blades. The second end parts are disposed farther forward in the rotational direction of the impeller than the first end parts. Each of the plurality of blades has an inner peripheral end part and an outer peripheral end part as end parts along a radial direction centered around the rotary shaft. The wall thickness of the inner peripheral end parts is greater than that of the outer peripheral end parts. Each of the plurality of blades has, toward the inner peripheral end part from a straight line that passes through a center point of a chord line of each of the plurality of blades and is perpendicular to the chord line, a maximum-wall-thickness part where the wall thickness reaches a maximum.
