Instant heater for dishwashing machine - uses tubular heating element wound round rinse water pipe with air duct around both directing heated air into dishwasher

摘要

The rinse water and the drying air for a dishwashing machine are heated by a tubular instant water heater (14) wound round the rinse water coupling pipe (11). Both rinse pipe and instant heater are surrounded by the air duct which directs hot air onto the dishes. The heater assembly is mounted below the bowl (10) of the dishwasher. The rinsing water is circulated through a pipe (11) which has a tubular heating element (14) wound over it. Surrounding the heating element is an air duct (12) with an outlet (17) at the base of the dishwasher bowl. Air is forced through the duct, over the heater and into the dishwasher by a fan (15). A thermostat (18) fitted in the wall of the air duct regulates the temp. of the heating element (14).
