AI Technical Summary

Technical Problem

The air guide plate driving device of existing air conditioners indoor units requires multiple motors to work together, resulting in complex control methods and prone to failures, affecting the working reliability of the air conditioner.

Method used

An indoor unit design is adopted, in which the air guide plate is opened and closed through a push rod and a driving part. The rotation center of the push rod coincides with the rotation center of the air guide plate. Only one driving part is needed to realize the rotation of multiple open positions and closed positions of the air guide plate.

Benefits of technology

The motion control logic of the air guide plate is simplified, the possibility of failure occurs, the working stability of the air conditioner is improved, and the production cost is reduced.

Abstract

The present invention provides an indoor unit, an air conditioner and a control method for the indoor unit. The indoor unit includes a housing assembly, the housing assembly has an air outlet; an air guide plate is connected to the housing assembly, the air guide plate has a plurality of first open positions for opening the air outlet, and the air guide plate has a closed position for closing the air outlet; a first transmission assembly includes a push rod, the first transmission assembly is connected to the air guide plate through the push rod; a first driving unit is connected to the first transmission assembly, the first driving unit drives the first transmission assembly so that the push rod drives the air guide plate to be located at any first open position and closed position; by adopting the technical solution of the present application, the indoor unit only needs to set one driving member to drive the air guide plate to reach the air guide position, and the indoor unit does not need multiple motors to work together, which effectively solves the problem that the existing indoor unit is more prone to failure.
