The inventions provides a portable multi-functional washing
machine which is characterized in that the main
machine is placed at the upper portion. The main
machine comprises a machine shell and a
handle. A functional key group and a protection switch are placed on the
handle. A
DC motor is mounted in the machine shell. A motor main shaft is connected with a hollow shaft. A retractable is placed in the hollow shaft and is fixed to the hollow shaft through fastening devices such as top thread. The lower end of the retractable shaft is provided with a wave
impeller. The height of the wave
impeller can be adjusted and fixed. A pedestal is located under the machine shell. A fastening
clutch drive mechanism is placed in the machine shell pedestal. The fastening
clutch can be controlled to hold tight or release a cylinder rim. The wave
impeller of the washing machine is in conical shape. The surface of the wave impeller has a vortex convex wing which plays the double functions of the wave impeller and a agitation stick to facilitate the forming of vortex turning
water flow. The work procedure of the washing machine comprises the steps of firstly inserting the wave impeller in the cylinder containing suitable amount of water and clothes, then positioning and fastening the main machine onto the cylinder to fix the main machine solidly, pushing the button group to set the parameters to start washing, after the set time expires, the washing being stopped. During the washing, if it's necessary to stop the washing machine or take out the main machine for accidental reasons, the protection switch under the
handle can be switched on by a touching force which stops the washing machine and brakes.
