Abstract

1468870 Dish-washing machines EUROPE MFG TRUST REG 16 Aug 1974 [9 July 1974] 36275/74 Heading A4F [Also in Division G1] The supply of liquid to a tank 1, e.g. in a dishwashing machine, is controlled by a valve (not shown) which is actuated electrically by a diaphragm switch 15. To ensure positive operation of this switch the diaphragm 16 is connected via a tube 14 with a chamber 9 so that when the liquid level in tank 1 reaches its maximum 2, some of the liquid is siphoned via tube 8 into the chamber 9 producing a sudden increase in the airpressure in the tube 14. The siphon tube 8 remains filled and, when in a later stage of operation, the tank 1 is emptied by a draining pump 6 the liquid level in chamber 9 is reduced at the same time as that in the tank 1 until it reaches the minimum 3 when the siphon is broken and chamber 9 is connected to the atmosphere through tube 10. A filling tube 17 is provided so that clean liquid is fed into the chamber 9.
