<p>To reduce energy wastage due to premature loss of hot rinse water in a mechanical warewashing machine (1) for sequential washing of a series of loads, each being subjected to a wash cycle in which it is doused (23, 25) with a wash liquor from a liquid delivery system (15, 17), the liquor being collected in a tank (7) disposed below the load (9, 11) and then, to a rinse cycle in which it is doused with rinse water which falls into the wash liquor already in the tank, the rank being provided with an overflow pipe (35) for limiting the liquid level (36) therein, the overflow pipe is provided with a siphon portion having a first opening (47, 55) disposed so as to be essentially below said liquid level and a second smaller opening (48, 56) above the liquid level so as to equalise the pressure at the top of the overflow pipe and above the liquid in order to prevent a siphonic action, thereby causing substantial mixing of the rinse water with the wash liquor before any of the water exits through the overflow pipe.</p> |
