Definitions

  • the present invention relates to a dishwasher and a method for operating a dishwasher.
  • a rinse program includes, for example, the partial program steps of pre-rinsing, cleaning, intermediate rinsing, rinsing and drying.
  • the different wash programs are created from these components, with further parameters such as the amount of detergent used, the amount of water, the water temperature and / or the water pressure , for which individual subprogram steps are defined.
  • eco-programs have been developed against the background of a resource-saving operation, which have a lower water and energy consumption and / or operated with less detergent than standard programs and yet should ensure a comparable cleaning result.
  • This is achieved by various measures, which overall make the rinsing process take more time, which is often unproblematic, for example when the dishwasher is running overnight.
  • rapid programs have been developed that realize a corresponding cleaning result with increased use of water and energy.
  • an object of the present invention is to provide an improved dishwasher.
  • a dishwasher in particular a domestic dishwasher, with a control device for carrying out a number of wash programs for washing a wash ware is proposed.
  • the dishwasher has an input means for detecting a user input to shorten an ongoing selected wash program.
  • the control device is adapted to adjust the current selected wash program in response to the detected user input such that a remaining wash duration of the adjusted selected wash program is shorter than a regular remaining wash duration of the currently selected wash program.
  • Such a dishwasher has the particular advantage that a user can accelerate the current wash program at any time.
  • the current selected wash program is adjusted so that the remaining part of the wash program is shortened.
  • An advantage of this is, in particular, that the wash program is continued at the point at which the currently selected wash program is current. This avoids repeating parts of the wash program, which saves both time and resources.
  • the selected wash program is an energy-efficient wash program with a relatively long run time of 240 minutes. After a running time of 60 minutes, the user input for shortening an ongoing selected wash program via the input means, which is designed for example as a button.
  • the control Apparatus that performs the current selected wash program then adjusts the remaining portion of the current selected wash program so that the remaining wash duration is only 60 minutes. Compared to the regular course of the currently selected washing program, for example 120 minutes are saved in this way.
  • the control device can be implemented in hardware and / or software technology.
  • the controller may be implemented as a computer or as a microprocessor.
  • the control device can be designed as a computer program product, as a function, as a routine, as part of a program code or as an executable object.
  • the control device comprises further, not described functions that ensure operation of the dishwasher.
  • the control device has, for example, a memory unit in which a number of washing programs are stored. The different washing programs are provided for different purposes and have different specifications, such as, for example, a quantity of water, a water temperature, dosing times for different dishwashing detergent components and the like.
  • an energy-saving flushing program can be provided which rinses in a particularly energy-efficient manner.
  • an intensive rinsing program can be provided, which achieves good cleaning results even with particularly strong and / or persistent soiling of the items to be washed.
  • a quick flushing program may be provided, which performs a flushing process particularly quickly.
  • the control device reads, for example, one of the rinsing programs from the storage unit and stores this in a temporary store, for example a cache.
  • the rinse program stored in the buffer is referred to herein as a selected rinse program.
  • the control device controls the other structural units of the dishwasher, such as a valve, a pump or a heating coil, as provided in the washing program.
  • the control device the specifications of the wash program works from step by step until the wash program to go through and the flushing is finished with it.
  • the input means for detecting the user input is designed, for example, as a push-button. The user input is made by pressing the button. The control device detects the actuation of the button. The control device then adapts the remaining remainder of the currently selected rinse program in such a way that the remaining runtime of the adjusted rinse program is shortened compared to the regular remaining runtime.
  • control device for example, by overwriting the not yet processed part of the washing program stored in the buffer with the adapted part of the washing program and subsequently carrying it out. In this way, it is ensured that the "standard" flushing programs stored in the storage unit are not affected by the adjustment.
  • the input means may also be arranged to allow a more complex input, such as a knob. Then, by operating the rotary control, the user can, for example, also enter a period of time by which the currently selected washing program is to be shortened as a function of the angle of rotation.
  • the adjustment of the remaining part of the currently selected wash program can be done in several ways. In particular, this depends on the type of user input. For example, a push-button may be provided as input means, which merely transmits a trigger signal to the control device. The trigger signal then triggers, for example, a predetermined adaptation of the wash program, in particular in order to achieve a minimal short remaining wash duration. This can be done by replacing the remaining part of the currently selected wash program with the corresponding part of a quick wash program. For example, the quick-wash program forms the shortest possible wash program.
  • a set of relations can be stored in the control device for adaptation, which represent a ratio of the scavenging effect achieved to the required time.
  • These relations are, for example, functions of a respective parameter, for example the water temperature, a pump speed, a water pressure and / or a quantity of water.
  • the adaptation can then take place by means of an algorithm, for example an optimization algorithm, the individual or all of these parameters at least for individual parts of the remaining part of the current selected wash program adapts and thus realizes a shortened residual maturity.
