Impeller mounting structure of air conditioning device

Abstract

An impeller mounting structure of air conditioning device is provided, including an electric machine arranged between a condenser and an evaporator and a condenser impeller and an evaporator impeller. The electric machine is mounted to an air duct casing of the condenser. The condenser impeller and the evaporator impeller are mounted to a shaft of the electric machine at the same side of the electric machine. A central air duct casing is arranged between the condenser impeller and the evaporator impeller. The evaporator impeller is mounted inside the evaporator air duct casing. The condenser impeller and the evaporator impeller are provided with mated self-locking structures. The mounting structure provides the efficacies that the impeller mounting structure of air conditioning device makes the manufacturing and assembling simplified, the size of a movable air conditioning device reduced, balance of electric machine in operation enhanced, and the number of parts assembled reduced.
