Definitions

  • the present invention relates to a dishwasher and a method for operating a dishwasher.
  • a washing program has, for example, the sub-program steps pre-rinsing, cleaning, intermediate rinsing, final rinsing and drying.
  • the different washing programs are created from these modules, with parameters such as the amount of cleaning agent used, the amount of water, the water temperature and/or the water pressure , can be defined for the individual subprogram steps.
  • eco programs have been developed to ensure that operations are as resource-efficient as possible, which have lower water and energy consumption and/or are operated with fewer cleaning agents than standard programs and are still intended to ensure a comparable cleaning result. This is achieved through various measures, which overall result in the washing process taking more time, which is often not a problem, for example if the dishwasher is running overnight.
  • WO 2010/012696 A2 discloses a dishwasher with a sorption drying system.
  • the dishwasher has a washing container and a control device which is set up to control the intended operation of the dishwasher by means of a washing program.
  • the dishwasher also has input means connected to the control device for modifying the washing program. Modifications are also suggested to shorten program runtime.
  • an object of the present invention is to provide an improved dishwasher.
  • a dishwasher in particular a household dishwasher, is proposed with a control device for carrying out a number of washing programs for washing items to be washed.
  • the dishwasher has an input means for recording a user input to shorten a current selected washing program.
  • the control device is set up to adapt the current selected washing program depending on the detected user input in such a way that a remaining washing time of the adapted selected washing program is shortened compared to a regular remaining washing time of the current selected washing program.
  • Such a dishwasher has the particular advantage that a user can accelerate the current washing program at any time. This means that as soon as the user makes a user input to shorten a current selected washing program via the input means, the current selected washing program is adjusted such that the remaining part of the washing program is carried out in a shortened manner. What is particularly advantageous here is that the washing program continues at the point at which the currently selected washing program is current. This avoids repeating parts of the washing program, which helps save both time and resources.
  • the selected washing program is an energy-saving washing program with a relatively long running time of 240 minutes.
  • the user input to shorten a running selected washing program is made via the input means, which is designed, for example, as a button.
  • the control device which carries out the current selected washing program then adjusts the remaining part of the current selected washing program so that the remaining washing time is only 60 minutes. In this way, for example, 120 minutes are saved compared to the regular sequence of the current selected washing program.
  • the control device can be implemented in terms of hardware and/or software.
  • the control device can be designed 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 includes additional functions not described here 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 intended for different purposes and have different specifications, such as a quantity of water, a water temperature, dosing times for different dishwashing detergent components and the like.
  • an energy-saving washing program can be provided which washes particularly energy-efficiently.
  • an intensive washing program can be provided, which achieves good cleaning results even when the items to be washed are particularly heavily and/or stubbornly soiled.
  • a quick rinsing program can be provided, which carries out a rinsing process particularly quickly.
  • the control device reads, for example, one of the rinsing programs from the storage unit and stores it in a buffer, for example a cache.
  • the washing program stored in the buffer memory is referred to here as the selected washing program.
  • the control device then controls the other structural units of the dishwasher, such as a valve, a pump or a heating coil, as provided in the washing program. In this way, the control device processes the specifications of the washing program step by step until the washing program has been run through and the washing process has ended.
  • the input means for detecting the user input is designed, for example, as a button.
  • the user input occurs by pressing the button.
  • the control device detects the actuation of the button.
  • the control device then adjusts the remaining amount of the currently selected washing program so that the remaining running time of the adapted washing program is shortened compared to the regular remaining running time.
  • the control device achieves this, 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 then carrying it out. This ensures that the “standard” washing programs stored in the storage unit are not affected by the adjustment.
  • the input means can also be designed in such a way that a more complex input is possible, such as a rotary controller. Then, by operating the rotary control depending on the angle of rotation, the user can, for example, enter a length of time by which the currently selected washing program should be shortened.
  • Adjusting the remaining portion of the current selected wash program can be done in various ways. In particular, this depends on the type of user input.
  • a button can be provided as an input means that only transmits a trigger signal to the control device.
  • the trigger signal then triggers, for example, a predetermined adjustment of the washing program, in particular in order to achieve a minimally short remaining washing time. This can be done by replacing the remaining part of the currently selected washing program with the corresponding part of a quick washing program.
  • the quick rinse program for example, represents the shortest possible rinse program.
  • a set of relations can be stored in the control device for adjustment, which represent a ratio of the flushing effect achieved to the time required.
  • 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 adjustment can then be done using an algorithm, for example an optimization algorithm, the individual or all of these parameters adjusts at least for individual parts of the remaining part of the currently selected washing program and thus realizes a shortened remaining running time.
  • the control device is set up to adapt the currently selected washing program depending on the user input while ensuring a predetermined cleaning result.
  • a specified cleaning result refers, for example, to a specified minimum cleanliness and/or a specified drying state.
  • the specified cleaning result corresponds to the cleaning result that would have been achieved if the selected washing program had been carried out regularly.
  • the specified cleaning result is determined, for example, in the European standard EN 50242.
  • the cleaning result is divided into grades from 1 to 6, with a higher number indicating a better cleaning result.
  • a cleaning result that is better than 4 is considered very good.
  • the specified cleaning result is a cleaning result that corresponds to grade 4.
  • This embodiment has the particular advantage that a user can be sure that the cleaning result achieved corresponds to his expectations even if the current washing program is shortened.
  • the remaining washing time of the adapted selected washing program is shortened by a predetermined period of time compared to the regular remaining washing time of the current selected washing program.
  • the user specifies a time period by which the remaining rinsing time of the currently selected rinsing program should be shortened.
  • the control device is then set up to adapt the current selected washing program in such a way that the remaining washing time of the adapted selected washing program is shortened by the predetermined period of time. This allows the user has full control over the remaining washing time of the dishwasher.
  • the adjustment is carried out in particular in compliance with a specified cleaning result.
  • the remaining washing time of the adapted selected washing program is maximally shortened compared to the regular remaining washing time of the current selected washing program.
  • the control device adapts the current selected washing program so that the adapted selected washing program corresponds to this optimal washing program.
  • the optimal washing program can also depend on the currently selected washing program. If, for example, a very gentle washing program is selected because the items to be washed are particularly sensitive, it can be provided that the control device takes this into account when adjusting the remaining part of the current selected washing program and, for example, does not exceed a predetermined maximum water temperature.
  • the washing programs each comprise a sequence of partial program steps.
  • the control device is set up to adapt the sequence of partial program steps for the current selected washing program depending on the user input. Additionally or alternatively, the control device is set up to adjust parameters for individual sub-program steps of the current selected washing program depending on the recorded user input.
  • control device is set up to omit individual sub-program steps and/or to adapt a parameter, for example the water temperature, in only one of the sub-program steps.
  • the partial program steps include pre-rinsing, cleaning, intermediate rinsing, final rinsing and/or drying.
  • the parameters for the partial program steps include a quantity of water, a water temperature, a pump speed, a water pressure, a fan speed and/or a time period.
  • the user input includes a time period, a time and/or a trigger signal.
  • a user may enter, for example, a preferred end time for the end of the current washing program as a time.
  • the control device is then set up to adapt the current selected washing program in such a way that the adapted selected washing program is ready at the entered time.
  • the input means is designed as a button, a rotary knob, a slider, a touch-sensitive surface of a touchscreen and/or a wireless interface.
  • the input means is designed as a wireless interface, and the user input can be detected via a mobile interface device.
  • the dishwasher user is provided with an app that they can run on a smartphone.
  • the smartphone establishes a communication connection with the wireless interface of the dishwasher.
  • the user can then make a corresponding entry in the dishwasher app, for example on the touch-sensitive screen of their smartphone.
  • the input is transmitted to the wireless interface and detected by the control device as the user input for shortening the current selected wash program.
  • the dishwasher transmits to the app an expected end time of the current selected washing program and/or the adapted selected washing program. The user is then informed at all times when the rinsing process will be completed.
  • a method for operating a dishwasher with a control device for carrying out a number of washing programs for washing items to be washed is proposed.
  • the dishwasher further has an input means for recording a user input to shorten a current selected washing program.
  • a run of a selected washing program from a number of washing programs is started.
  • the user input is recorded.
  • a remaining part of the current selected washing program is adjusted depending on the detected user input such that a remaining washing time of the adapted selected washing program is shortened compared to a regular remaining washing time of the current selected washing program.
  • the adjusted remaining part of the selected washing program is carried out.
  • This method advantageously allows a user to intervene in the ongoing operation of a dishwasher in such a way that the dishwasher completes the current washing program more quickly. This is advantageously done while maintaining a predetermined cleaning result, in particular a predetermined minimum cleanliness and a predetermined minimum dryness of the items to be washed.
  • a computer program product which causes the method according to the second aspect to be carried out on a program-controlled device.
  • a computer program product such as a computer program medium
  • a storage medium such as a memory card, USB stick, CD-ROM, DVD, or even provided or delivered in the form of a downloadable file from a server on a network. This can be done, for example, in a wireless communication network by transmitting a corresponding file with the computer program product or the computer program means.
