PURPOSE: To lower the noise of a dish cleaning machine having spray nozzles rotating by the reaction of the injecting force of the cleaning liquid by dispersing, attracting kinetic energy and preventing vibration of inner wall thereof.

CONSTITUTION: Fine net 5 of 30 to 50 mesh is provided with stainless steel at the side peripheral surface and upper cage cover 6 of washing cages 7, 8 in a dish cleaning machine body W. The net 5 prevents cleaning ejected stream from colliding directly with the inner wall 11 of the machine to thereby lower the noise.
