Abstract

1469338 Dishwashers THORN DOMESTIC APPLIANCES (ELECTRICAL) Ltd 29 April 1975 [30 April 1974] 18912/74 Heading A4F [Also in Division G3] In a dishwasher having a timer with a plurality of switches 1, 2, 3, 7, 8, 14 for automatically controlling the washing cycle, a wash pump 30 for circulating water, a drain pump 32, an electricallyoperable valve 31 for controlling the supply of water, and a water level sensor 23 adapted to open the valve 31 should the water level fall below a predetermined value, the arrangement is such that during predetermined stages of the washing cycle part only of the hot water is drained, off by the drain pump 32 and, with the wash pump 30 operating, energized as shown in Fig. 3 by switches 7, 8 and 2, is replaced by cold water via the valve 31 energized by switch 1 and water level sensor 23 and thereafter all the resulting warm water is drained off by the drain pump 32, energized by switches 7 and 8, and is replaced by cold water when the water level sensor 23 acts to energize valve 31 via switch 1, articles being washed thereby avoiding thermal shock due to the replacement of all the hot water by cold at once. The circuit shown in Fig. 3 is programmed to operate as shown in Fig. 5. An initial hot prewash is performed in timing periods 1-5 and in periods 6-8 the hot water is replaced by cold as described in the preceding paragraph. A hot wash is carried out during periods 9-20 with detergent being dispensed from a valve 39 at period 13 or 19. The temperature of the hot wash is controlled by thermostats 36, 40, manually-operable switch 35 and heaters 37, 38. During subsequent periods 21-23 hot water is again replaced by cold. Two cold rinses occupy periods 24-32 and a final hot rinse takes place during periods 33-41, rinse aid liquid being added by valve 33 at period 36. Finally hot air drying is performed by heater 37 during periods 42-60. The description of divisional Specification 1469339 is substantially identical but the claims relate to the arrangement and control of heaters 37, 38.
