Adjustable air sweep mechanism for a room air conditioner

摘要

The discharge air sweep mechanism for an air conditioner is provided with slippage in its drive linkage such that the position of the vanes can be manually adjusted when the drive motor is turned off, or if the vanes become jammed during normal air sweep operation, the drive motor can continue to operate without damage to the mechanism. In one form of linkage, frictional engagement is provided by a pair of arms that are biased together with engaged member disposed therebetween, with the engaged member being allowed to slide between the arms upon the occurrences of either of the above mentioned conditions. Vane stop means is provided to automatically recalibrate the relative positions when normal air sweep operation is resumed.
