Definitions

• the invention relates to a method for operating a Household appliances, especially a washing machine or dishwasher, with a plurality of sequential user selectable executable programs.
• Household appliances of this type have a control device through which a consisting of several individual programs Washing or rinsing program carried out automatically can be without the user in the program flow must intervene.
• Certain programs or program parts can not only run within an overall program flow be, but can be. also separately from the user carry out. It is common, for example, a spin program to be carried out separately from a complete washing program sequence. If necessary, this spin program performed several times in succession at high speed.
• This operating state is actually from the manufacturer not provided and therefore it can under unfavorable circumstances overheating in the area of the bearings.
• This special problem could be a reduction in maximum speed be solved. However, that would be the function then also limited to those operating conditions in which a reduction in speed would not be necessary.
• the invention is therefore based on the problem of damage or to endanger components.
• each Program at least one on one stored in a memory Program-specific calculation rule to be used to determine the level of hazard assigned to a machine component which is then stored in the memory as a new key figure is modified, the execution of a program becomes, if the dimension figure exceeds or falls below a threshold or reached.
• the risk to components is avoided by the overall program sequence is broken down into individual programs and everyone Individual program a program-specific calculation rule is assigned. With a washing machine can a calculation rule for pumping, spinning and rinsing may be provided. In this way, the respective Risk potential of a program part taken into account become.
• the degree of danger is determined by a measure expressed so that different sized damage or hazard potentials are taken into account can.
• the current state of danger is taken into account by placing the calculation rule on an in a key figure stored in a memory is used. Subsequently the newly calculated measure is saved as a measure, the next step in the program is used as the input variable.
• Program or program part can if necessary be modified.
• the method according to the invention is useful for everyone single program to be carried out, the current Degree of danger of the machine, expressed by the in Memory stored key figure is taken into account. After Calculation of the new dimension number is saved and is available for the following program.
• the program is therefore carried out as a loop, i.e. if a user a certain device function three times in a row carried out, then the inventive method three times run through.
• a particularly high level of security against component damage is achieved if the calculated dimension with a Threshold is compared and the execution of the following Program is modified when this threshold is exceeded or undershot or reached.
• the threshold is determined and defined device-specifically a limit that should not be exceeded, otherwise a reduction in the lifespan of components or hazards' would be expected from machine components. For example, if the threshold is exceeded the program to be executed can be modified so that none Hazards are to be expected.
• This program modification can be achieved by restricting operational areas can be limited, for example, a speed or a certain temperature can be reduced or a cooling fan can be switched on.
• each program has a first Calculation rule to be carried out at the start of the program for the dimension number and a second one to be carried out at the end of the program Calculation rule assigned for the dimension figure is and the exceeding or falling below or reaching of the threshold value at program start and / or at program end is checked.
• This will make the current one Device state considered.
• the query as to whether the threshold for the hazard e.g. can be exceeded performed at the beginning of a program as well as at the end become. In the first case, this can be done immediately program to be executed are modified, in the second case the change affects the following program.
• Simplification can be provided that the calculation rules for the start and end in one function be summarized and carried out sequentially.
• the method according to the invention can be very programmatic can be easily realized if the calculation rule includes the use of basic arithmetic operations.
• the key figure can be in the form of a Spin program can be increased by the value "1".
• Another one Skidding leads to a further increase in Key figure by the value "1" so that the current level of risk from the accumulation of each individual's contributions Program results.
• the threshold is in this case expediently chosen as a positive number, with its over or Falling short of or reaching the next one to be executed Program is modified.
• a calculation rule can also provide that the in Memory stored key figure replaced by another value becomes.
• the execution of a wool program brings one Cooling of the storage area with itself, so that after it Execution practically no danger potential exists. Accordingly, the key figure can e.g. can be set to "0".
• the key figure is displayed when the machine is started up also set to "0" in memory.
• the method according to the invention can be particularly Apply advantage to washing machines or dishwashers. These can run a variety of different programs. It is therefore appropriate, the individual programs or program parts in those with positive, neutral, negative and indifferent effect on a component of the household appliance to classify. It is also easily possible for the hazard different machine components, by having a corresponding one for each machine component component-specific key figure is provided.
• the first serves as a start function and the second as Stop working.
• the start function can provide that the key figure remains unchanged remains and is set to "0" at the end of the program.
• at a program with neutral behavior can be provided be the key figure for the start function and the end function remains unchanged.
• the start function can provide that the Key figure remains unchanged and at the end of the program or at the end function is increased by a certain value.
• Farther programs with indifferent behavior are possible, for these the key figure can be determined by the start function, i.e. be set to "0" at program start and at Program end by the end function on a certain Value can be increased.
• the invention can provide that if the value is exceeded or undershot or reached Threshold value the speed or working time of a machine component is limited and / or the machine function is locked and / or a heating or cooling element on or is turned off. It can alternatively or additionally be provided be that in this case a signal to the user and / or given to a control device of the machine becomes.
• the invention relates to a household appliance, in particular a washing machine or dishwasher with a plurality of sequentially executable programs that can be selected by the user, the one trained to carry out the method Has control device.
• the control device can do this of the household appliance a computing device with a writable and erasable memory and include a software program.
• Line 3 shows the functions for the final spin. It is a spin program with the highest speed of the device, e.g. at 1800 rpm. lies.
• Table 1 the storage value not influenced at start (memory + 0), after the key figure when the spin program is carried out in memory increased by the value "1" (memory + 1). Accordingly there is an increased degree of danger after the final spin in front.
• the final spin is one of the programs with negative behavior.
• the memory value set to "0" since there is no danger at this time is available.
• the final spin is made by the user carried out. So it's the ones listed in Table 1 Calculation rules for the final spin on the Applied storage value. The result is "0" for Start and the value "1" at the end.
• the threshold has the value "2". The execution of a Program is modified when this threshold is exceeded. Because the current value in memory is smaller than the threshold is done after the final spin no reaction in the form of a program modification.
• the next step is to run the "Pump” program. It again becomes the calculation rule given in Table 1 applied to the storage value that was at startup Is "4" and "4" at the end. Since it's pumping is a neutral program, the memory value and the degree of danger does not affect. So it stays with the speed limit. Then the user chooses that Program "wool 40 ° C", the corresponding memory values are "4" at the beginning and "0" at the end because the Wool program is a program with positive behavior. After the wool program, the storage value is set to "0" set. Because the storage value is less than the threshold the speed limitation is not applicable, i.e. the machine can be operated at maximum speed again.
• the start value in the memory is "0", the end value in the memory is "1". It is important that the final spin in the Contrary to the previous spin cycle with the maximum speed can be made.
• the program "Cottons 30 ° C” is executed. According to the calculation instructions assigned to this program the code in the memory is initially set to "0" set and increased by the value "1" at the end. Because the threshold is not exceeded, there is no reaction or Modification of a program.
• the last program is Wool program executed with the storage value at the beginning is not influenced, i.e. it continues to be "1" on At the end of the wool program, the storage value is set to "0". Since the hazard threshold has not been exceeded, there is no restriction of operation.
