Abstract: The present invention relates to a wet duster module of a cleaner for sucking or wiping dust or foreign substance in an area to be cleaned by discharging water to a duster. The wet duster module of the cleaner according to the embodiment of the present disclosure can cause forced convection of the air in the inner space through the passage hole that communicates the suction passage and the inner space of the module housing without having a separate cooling module. Therefore, the cooling efficiency of the driving unit disposed in the inner space can be increased. Accordingly, this can not only contribute to the miniaturization of the wet duster module but also adopt the drive motor with higher output, thereby enabling high performance of the wet duster module.

Abstract: A compressor is provided that may include a refrigerant flow path provided in a rotational shaft so as to guide a refrigerant gas. The rotational shaft operates a compression device using a drive force of an electric motor. In such a structure, the refrigerant gas may be directly discharged to a discharge space without passing through other portions such that flow path resistance may be minimized.
