Abstract (en)
[origin: EP0898928A1] The invention relates to a dishwashing machine with a lower and upper spray arm and a circulating pump which sucks in rinse water from a sump of the rinsing container and feeds the spray arms, the impeller of which projects into the rinsing container and is surrounded by a pump casing which is provided with inlet openings. The installation of a tubular heating element for heating the rinse water may thus be used for reducing the parts and assembly costs and also for improving the heat efficiency in that the pump casing is formed by a tubular heating element, the connections of which are directed to the lower side of the base of the rinsing container which is designed as a downcomer and in that the upper end of the tubular heating element is also fixed in a filter covering the downcomer and/or in a bearing element which is held in the filter and provided with exits to the spray arms.
