Cross-flow type blower of a dual-unit type room air conditioner and a structure for engaging a motor shaft

摘要

It discloses a cross-flow fan and the cross flow fan of the separate type air-conditioning rooms by connecting a simple structure of the motor shaft and the motor shaft fixing structure for driving thereof as a driven member which is provided on the indoor unit of a separate type air-conditioning room. The subject innovation disclosed cross-flow fan (2), the motor shaft fixing part 20, the motor shaft 30 is inserted, a motor shaft 30 of the not fall to a fixed pin 40 on the motor shaft fixing part (20) It is fixed. Fixing pin 40 is inserted through the pin groove 31 formed in the pin hole 21 and a pin hole 21, the motor shaft 30 in the position corresponding to the formed and a motor shaft portion 20, and a motor shaft with respect to the portion 20 is fixed so as to fall the motor shaft 30. The interior of the motor shaft fixing part (20) has inserted in the projection (22) intended to hold the position of the motor shaft 30 is injection molded integrally with the motor shaft fixing part (20). Therefore, it is not necessary to provide a separate stopper, as in the prior art. With this structure, by inserting the motor shaft 30 to the motor shaft fixing portion 20 of the cross-flow fan (2), the pin groove 31 of the pin hole 21 and the motor shaft 30 of the motor shaft fixing part (20) It can be matched to connect to secure the fixing pin motor shaft 30 to the motor shaft fixing portion 20 of the cross-flow fan in a simple way fitting (40) thereto.
