Definitions

  • the present invention relates to a dishwasher and a method for operating a dishwasher.
  • dishwashers which have different spray devices, wherein it is possible for a user, for example, to manually switch between the different spray devices.
  • One of the spray devices can be designed to provide a special rinsing zone, which achieves a particularly high cleaning performance or is set up for items to be molded in a specific way.
  • US 2015/0250374 A1 shows a dishwasher in which a bottle flushing device can be switched on by means of a manually switchable valve.

  • the switching position of such additional spraying devices can have an effect on the cleaning result of the dishwasher if, for example, not enough washing liquor is present in the washing cycle in order to supply all spraying facilities with washing liquor, or because a liquid pressure of the washing liquor is too low. It is therefore advantageous if the switching position of the additional spray device is known, so that it can be adequately responded to. However, it is complicated and expensive to arrange a corresponding sensor in the washing compartment of such a dishwasher. Furthermore, such a sensor would be susceptible to errors due to the conditions in the washing compartment.
  • DE 10 2007 017 274 A1 describes a method for detecting the position of a closure element in a water separator of a dishwasher. In this case, a signal value of the circulating pump is detected and compared with a stored signal value which corresponds to a reference position of the closure element. In this way it can be seen when the closure element is in the reference position.

  • Such a dishwasher has the advantage that it is possible reliably and in a self-calibrated manner without additional components to determine the current switching state of the third spraying device. Thus, by using already existing components, an additional function can be fulfilled which makes operation of the dishwasher more reliable.
  • the dishwasher has, for example, a rinsing chamber with washware receptacles arranged therein, wherein the rinsing chamber can be closed by means of a door and, in the closed state, forms a wash chamber.

In this way, the two hydraulic systems can be acted upon alternately with rinsing water. Furthermore, a third position of the water distributor may be provided, in which both hydraulic systems are simultaneously supplied with wash liquor, wherein a quantitative ratio of the quantity of wash liquor supplied to the first hydraulic arrangement to the quantity of wash liquor supplied to the second hydraulic arrangement may be freely selectable.
  • the respective hydraulic arrangement preferably runs outside the rinsing chamber, but can also run in sections within the rinsing chamber.

Abstract

L'invention concerne un lave-vaisselle (1), en particulier un lave-vaisselle domestique, équipé d'un premier dispositif d'aspersion (112) auquel est associé un premier agencement hydraulique (110) et destiné à mettre à disposition une première zone de lavage, d'un deuxième dispositif d'aspersion (122) auquel est associé un deuxième agencement hydraulique (120) et destiné à mettre à disposition une deuxième zone de lavage, le premier agencement hydraulique (110) et le deuxième agencement hydraulique (120) pouvant être alimentés en liquide de lavage depuis un dispositif de pompe (140) actionné au moyen d'un flux de pompe (142), et d'un troisième dispositif d'aspersion (132) destiné à mettre à disposition une zone de lavage intensif, auquel est associé le premier agencement hydraulique (110) ou le deuxième agencement hydraulique (120), le troisième dispositif d'aspersion (132) présentant un premier état de commutation et un deuxième état de commutation, le troisième dispositif d'aspersion (132) étant déconnecté de l'agencement hydraulique (110, 120) associé dans le premier état de commutation et relié à l'agencement hydraulique (110, 120) associé dans le deuxième état de commutation, et d'un dispositif de commande (150), conçu pour déterminer un état de commutation en cours du troisième dispositif d'aspersion (132) en fonction d'une différence du flux de pompe (142) entre une alimentation en liquide de lavage du premier agencement hydraulique (110) et une alimentation en liquide de lavage du deuxième agencement hydraulique (120).
