PROBLEM TO BE SOLVED: To provide a means to realize a simple and inexpensive washing machine which needs neither electric power nor detergent, nor a great effort. SOLUTION: The washing machine which needs neither electric power nor detergent is achieved by making water supplied by a water supply means such as a waterworks, recover heat from waste water through a heat exchanger, subsequently heating by a heating means such as solar heat and pouring into a washing tub at a sufficiently high temperature. When the washing tub is sufficiently filled with heated water, an opening and closing valve is closed and pressure in the washing tub is sufficiently increased to the pressure of the water supply means.
