The present invention generally relates to a movable air conditioning device, and more particularly to an impeller mounting structure of a movable air conditioning device.
DESCRIPTION OF THE PRIOR ARTHeretofore, the ways for mounting an impeller or a movable air conditioning device are (1) that impellers are respectively mounted to an electric machine of a condenser or an electric machine of an evaporator, the being disadvantageous in that two electric machines are used to respectively coupled to air ducts, leading to high cost and complicated assembling; (2) that a single electric machine is used and impellers are respectively coupled to opposite ends of the electric machine, this being disadvantageous in that the electric machine must provide an extended shaft and poor balance often results in the operation of the electric machine, the size is bulky, and assembling is complicated. Further, the inside and outer air duct cases are constituted by four components.
Thus, it is a challenge for the development of the industry to provide a solution to overcome such problems of the existing devices.
SUMMARY OF THE INVENTIONIn view of the above discussed problems, the present invention aims to provide a structure for mounting inside and outside impeller of a movable air conditioning device, which allows for easy assembling with a less amount of components used.
The technical solution provided by the present invention is as follows:
An impeller mounting structure of air conditioning device is characterized by comprising an electric machine arranged between a condenser and an evaporator and a condenser impeller and an evaporator impeller, wherein 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; and the condenser impeller and the evaporator impeller are provided with mated self-locking means.
The self-locking means adopted in the present invention comprises a projection formed on the condenser impeller or the evaporator impeller and a recess formed in the evaporator impeller or the condenser impeller to receive the project to fit therein.
The present invention 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.
