Abstract:
A washing machine capable of reducing a mechanical force acting on washed matter in a washing process, wherein high density detergent liquid is produced by diluting detergent with a small amount of city water of 80 to 300 times the volume of the detergent, and sprayed and penetrated into the pre−wetted washed matter while diluting the high density detergent liquid to a detergent density of 5 to 20 times to act the chemical washing force of the detergent acting on the contamination adhered to the washed matter so as to increase a washing efficiency, whereby, since a mechanical force acting on the washed matter when washing by feeding the amount of water necessary for the washing is reduced, the possibility of the damage and entanglement of the washed matter can be reduced.
