Problems solved by technology

However, the tolerances of the individual pressure switches affect each other, thereby increasing the tolerance between the two water levels
In addition, traditional pressure switches require a lot of space and cost for components, which also makes the production of dishwashers too complicated

Embodiment Construction

[0081] Such as figure 1 As shown, the dishwasher 10 includes a wash basin 12 for receiving laundry (not shown), the wash basin 12 is composed of a rear wall (on the left side), two opposing side walls (not shown), a top wall (on the top ), the bottom (at the lower end of the wash basin, with an opening fixed to the storage tank 16 for collecting water), the front opening (right side, not indicated), which is defined in figure 1 The center is closed by the loading door 14 at the front. At least one dishwasher sprayer 18 is arranged in the wash tub 12 for spraying pressurized wash water on the laundry. Dishwasher sprinklers receive pressurized wash water from a dishwasher's circulation pump (not shown), which in operation draws water from a corresponding opening (not shown) in the storage tank.

[0082] An analog pressure sensor 20 is arranged next to the storage tank 16 and is hydraulically connected to the storage tank by a connecting pipe. The storage tank includes an air ...

Abstract

A method for filling a wash tub (12) of a dishwasher (10) with water, wherein the wash tub (12) comprises a water-collecting sump pot (16) that is fixed to an opening in its bottom and said method forms part of a program cycle for the operation of the dishwasher, said method comprising the subsequent steps of: (i) opening a water inlet (13) of the dishwasher and executing a static filling of the wash tub wherein a circulation pump of the dishwasher is kept deactivated, (ii) detecting a predetermined lower water level (22) inside the sump pot (16), and (iii) starting to measure the time for the static filling when said lower water level (22) is detected.

Description

technical field [0001] The invention relates to a method for filling the wash basin of a dishwasher with water, wherein the method forms part of a program cycle for the operation of the dishwasher. Background technique [0002] Known from DE19828768C2 is a method for the operation of a dishwasher, wherein the washing basin of the dishwasher is filled with clean water until a minimum operating water level is reached in the storage tank of the washing chamber, and said minimum operating water level is set such that washing dishes The cycle of the machine will not suck in air. The minimum working water level is measured by a water level sensor, which includes an air elbow and a pressure sensor. However, the accuracy of the prior art water level measurement is not sufficient for modern dishwashers, which require filling methods that use less water for ecological reasons. [0003] Pressure switches with a single on-off water level have often been used in the prior art to contro...
