Abstract (en)

[origin: EP0669099A2] A device for the control of the level of washing liquid in a dishwasher comprises a tank (11) with capacity equal to a fraction of the quantity of liquid to be loaded into a washing drum (1) of the dishwasher and fed through a feed solenoid valve (3), first means (14,15) for transferring the liquid from said tank (11) into a transfer recipient with a smaller capacity than the tank (11), which first means are actuated when the tank (11) has been filled and de-actuated when all the liquid contained in the tank (11) has been transferred, a pressure chamber (24) connected to said transfer recipient (12) whereto pressure detection means (27,28) are associated and which are actuated when the level of the liquid transferred into said recipient (12) exceeds a first preset level (L3) to cause the closure of said feed solenoid valve (3), and second means (16,13,30) for transferring the liquid from said transfer recipient (12) to the washing drum (1), which second means are actuated when the level of the liquid transferred into said transfer recipient (12) exceeds a second preset level (L4), higher than the first level (L3). <IMAGE>
