Abstract

1,164,637. Dish washing machines. KIENINGER & OBERGFELL FABRIK FœR TECHNISCHE LANFWERKE UND APPARATE. 5 Dec., 1966 [3 Dec., 1965], No. 543710/66. Heading A4F. [Also in Divisions D1, G1 and H3] In a liquid level control means such as for use in washing and washing up machines in which the liquid level is controlled electrically or electronically, at least one level sensing probe N V1 , N V2 N V3 , or N V4 , is arranged on the side wall of the machine, at the designed liquid level for the various operational stages of the machine, and a counterprobe N V0 common to the probe or probes N V1 to N V4 is arranged at the bottom of the machine and the arrangement is such that a programme controlled selection switch S is connected to one of the probes N V1 to N V4 to admit liquid to the machine via a valve 4 to the required level. The electric control circuit may include a Schmitt trigger circuit, Fig. 2 (not shown) or delay means in the input or the output of the circuit Figs. 3 or 4 (not shown).
