Improvement in the structure of a washing machine.

摘要

Clothes washing machine or dishwashing machine comprising an outer housing and a back wall that features an aperture delimited by edges (5) that are connected to the outer structure of said housing, said aperture being closed by a double-wall rear panel (1) forming a cavity (2) that extends almost all over the whole surface of said rear panel and is filled with noise-deadening material (3), preferably calcium carbonate. Said rear panel (i) is made of plastic material, in particular by the blow-moulding process; a metal net-like screen (6), which is connected to the grounding terminal of the machine, is applied on to said rear panel. The ballast means used in these machines consist of an outer enclosure (7) of preferably blow-moulded plastics, said outer enclosure being filled with ballast material comprising calcium carbonate (8).
