Abstract

This air conditioner has: an intake port into which air is suctioned; a blower that suctions the air from the intake port and generates an air flow; a box body that stores a control board for controlling an actuator provided to a main body; a lid that covers an opening of the box body; an electrical component box that has a flange part that fixes the lid to the box body and is positioned in the channel of the air flow; and a rectifying part that covers the flange part.

Description

Technical field [0001] The present invention relates to an intake air blower of the air conditioner. Background technique [0002] In the past, the air conditioner indoor unit is achieved by high winds quantify not only extended to reach the blown air from the room, but also improve the energy efficiency of the operation at the rated capacity. However, a high wind speed increases to quantization blower, sometimes referred to as a vane generates peak noise is the noise from the vicinity of the blower and the blower. This peak is also referred to as NZ sound tone. NZ noises become an integral multiple of the peak sound frequency and the number of blades of the rotational speed of the blower, to bring uncomfortable feeling to the user. Therefore, NZ tone indoor high wind becoming impediments to quantify. NZ produce sound there are multiple factors. The fan intake air flow disturbances due to turbulence of air flow generated pressure fluctuation is considered to be one of the factors...
