PROBLEM TO BE SOLVED: To provide a washer and a washing nozzle which can be satisfactorily used indoors in terms of safety management and hygiene and enables the optimum washing. SOLUTION: The washer is provided with a first heat exchanger which elevates the temperature of inflowing fluid (A) by using supplied vapor and allows the fluid (A) to flow out, a pressure pump which pressurizes the fluid (A) flowing into the first heat exchanger and, thereby, heats the same, a central ejection port and surrounding ejection ports which are separated from the center ejection port and are disposed around the same. The washer is further provided with a washing nozzle in which the center ejection port can eject the fluid (A) flowing out of the first heat exchanger and the surrounding ejection ports can eject fluid (B) supplied through another path. The washer is constituted in such a manner that ejection pressure of the fluid (B) is lower than the pressure of the fluid (A). COPYRIGHT: (C)2004,JPO
