A control method of a washing machine is characterized in that the washing machine controls to start a fan heating integrated device 4, hot air or steam enters a first channel 12 through an outlet end of an air supply/steam mechanism and then enters the interior of a washing barrel through a first communicating port 21 and a second communicating port, and clothes in the washing barrel are washed or dried.
In the washing process, the washing machine controls to start the fan heating integrated device 4, the fan heating integrated device generates steam, the steam enters the first channel 12 through the outlet end of the air supply/steam device and then enters the space above the impeller in the washing barrel through the first communicating port 21 and the second communicating port to wash clothes in the washing barrel;
or, in the drying process, the washing machine controls to turn on the fan heating integrated device 4, the fan heating integrated device generates hot air, the hot air enters the first channel 12 through the outlet end of the air supply/steam device, and then enters the space above the impeller in the washing tub through the first communicating port 21 and the second communicating port to dry the clothes in the washing tub.
Furthermore, in the steam washing process, the washing machine controls to turn on the fan heating integrated device 4, the fan heating integrated device generates steam, the steam enters the first channel 12 through the pipeline 41 and then enters the space above the impeller 3 in the washing tub 2 through the first communicating port 21 and the second communicating port to wash clothes; in the water washing process, the washing machine controls to start the fan heating integrated device 4, the fan heating integrated device generates hot air, the hot air enters the space above the impeller 3 in the washing barrel 2 through the first channel 21 and the second channel 31, rolling water flow from bottom to top is formed in the barrel, and the hot air and circumferential water flow generated by the impeller form spatial three-dimensional water flow together, so that the washing efficiency is effectively improved by increasing friction between clothes and washing water, in addition, the winding of the clothes can be reduced by the spatial three-dimensional water flow, meanwhile, the hot air has a heating effect on the washing water, and the washing efficiency of the clothes is improved by improving the temperature of the washing water; after dehydration, fan heating integrated device 4 is opened in the washing machine control, fan heating integrated device produces hot-blastly, hot-blastly get into first passageway 12 through pipeline 41, then get into the space more than the impeller in the washtub through first intercommunication mouth 21 and second intercommunication mouth, dry the clothing, the clothing in the washtub is piled up on impeller 3 naturally, hot-blastly through second intercommunication mouth and clothing direct contact to blow up the clothing and make the clothing unfold, can obviously improve drying efficiency, reduce the clothing fold.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
