Definitions
- the invention relates to a method for detecting the amount of crockery in the washing compartment of a dishwasher and a dishwasher for performing this method.
- a particular aim is to reduce energy consumption, since household appliances, in particular dishwashers, are categorized based on their energy consumption.
- An essential part of the energy consumption is used when heating up the rinse, since, depending on the selected rinse program, a liquid quantity of about 3 to 6 liters must be heated by a temperature difference of up to 50 ° C in each section of the program.
- conventional dishwashers offer the option of manually preselecting an economy program that significantly reduces water consumption or by selecting a so-called single basket rinsing that can reduce water consumption by up to approximately half, or in any case also significantly.
- the aim of these options is to optimally adapt the respective washing program and thus the required amount of water to the respective amount of dishes.
- the user has to preselect the above-mentioned, known savings options, the savings program or the single basket rinse.
- a single basket rinse cannot be selected, since despite the small number of crockery this is distributed among two baskets in the washing container due to the size of the individual dishes. Since the amount of crockery cannot be set precisely and only a distinction can be made between coarse crockery states, a larger amount of liquid is used than is necessary due to the amount of crockery.
- both the motor operating data of a circulating pump and the heating gradient in the dishwasher are recorded at least in a pre-winding phase and in a heating-up phase, and the recorded actual values are compared with stored target values on the basis of this target The actual value comparison determines the amount of dishes in the washing container and the washing program is adjusted accordingly based on the amount of dishes found.
- the engine operating data and the heating gradient are advantageously measured at specific time intervals.
- the engine operating data are used to detect the amount of dishes in the washing container, but also the temperature value which is necessary for heating the washing liquor.
- This value known as the heating slope, measures the temperature change of the water flowing through via a temperature sensor which is arranged, for example, at an outlet of the instantaneous water heater or another heating source which is intended for heating the washing liquor. If, for example, a certain amount of water is heated in the continuous-flow heater and directed onto the dishes by means of at least one spray device, temperature compensation takes place between the dishes and the washing liquor, the temperature change or the speed of the temperature change depending on the respective amount of dishes in the washing container.
- the rinsing liquor is pumped several times through the heating device, for example the instantaneous water heater, using a circulating pump, so that measuring the water temperature, for example at the instantaneous heater outlet or inlet, makes sense.
- the sole use of the heating slope data to detect the amount of crockery in the washing container is not sufficiently reliable, since the heating slope data can be significantly falsified due to the voltage differences that are always present in the public power grid. If, for example, the dishwasher is operated at a voltage of 250 volts instead of 230 volts AC, the heating slope measurement would underestimate the loading condition due to the high electrical power available, even with a washing container that is loaded with wash ware and pass on a signal to the program control device that the dishwasher is empty.
- the operating data of the motor also change with the voltage, i.e.
- the change in voltage or voltage fluctuations are measured and can therefore be incorporated into the assessment of the heating slope values or verified.
- the method according to the invention thus combines two measurement values obtained independently of one another, which can be attributed to different input variables, actual values. After the method according to the invention has recognized the amount of crockery in the washing container, the amount of water sufficient for this specific amount of crockery, which was also determined by empirical measurement data and stored in the program control device, can be determined, so that the water consumption can be significantly reduced due to the automatic adjustment of the amount of water.
- the present invention has succeeded in providing a method which is suitable for recognizing the amount of dishes in the washing compartment of a dishwasher in such a way that a program controller adapts the washing program to the respective amount of dishes.
- both the motor operating data of the circulation pump and the heating gradient are recorded by means of suitable sensors at least in a pre-winding phase and in a heating phase, the dishwasher having a program control in which the recorded actual values are stored Target values are compared, on the basis of this target / actual value comparison the amount of crockery in the washing container is determined and the washing program is adjusted accordingly based on the amount of crockery found.
