(54) | Weight sensing method for dishwashers |
(57) In a method for sensing the dish load in dishwashers, the water level in the machine
pool (7) is measured at first step by means of a water-level measuring unit and this
is reported to the machine's control unit; the upper nozzles (5) or lower nozzles
(4) are rotated to some extent at second step, by operating the machine's washing
pump (1); said pump (1) is stopped at third step, and some time is allowed for the
water present on the upper rack (21) or lower rack (22) to drain away; the water level
in the pool (7) is measured once more at forth step; and the load amounts at each
rack is determined by means of the control unit at fifth step, based on the difference
between the water levels measured at the first and forth steps; all these steps being
conducted separately both for the upper rack (21) and the lower rack (22).
