Abstract
A dishwasher and a method for detecting the quantity of dishes in the washing container of the dishwasher are provided. The method includes detecting data relating to the motor operation of a circulating pump and detecting data relating to the heat increase in the dishwasher during a pre-washing phase and a heating phase and comparing the detected data with stored target values. A quantity value for the quantity of dishes in the washing container is set based upon a comparison of the detected data with stored target values. The method also includes adapting the washing programme according to the set dishes quantity value.

A method for detecting the quantity of dishes in the washing container of a dishwasher, comprising:
- detecting both the motor operation data of a circulating pump and the heat increase in the dishwasher in a pre-washing phase and in a heating phase;
- comparing the detected actual values are compared with stored target values;
- and
- determining the quantity of dishes in the washing container as a result of the actual-target value comparison and the washing programme is adapted according to the quantity of dishes detected.
A dishwasher comprising:
- means for detecting both the motor operation data of a circulating pump and the heat increase in the dishwasher during at least in a pre-washing phase and in a heating phase;
- and
- a programme control in which the detected actual values are compared with stored target values, the programme control being operable to determine the quantity of dishes in the washing container as a result of the actual-target value comparison and to adapt the washing programme according to the quantity of dishes detected.
A method for detecting the quantity of dishes in the washing container of a dishwasher, comprising:
- detecting data relating to the motor operation of a circulating pump during at least one of a pre-washing phase and a heating phase;
- detecting data relating to the heat increase in the dishwasher during at least one of a pre-washing phase and a heating phase;
- comparing the detected data relating to the motor operation of a circulating pump and the detected data relating to the heat increase in the dishwasher with stored target values;
- setting a quantity value for the quantity of dishes in the washing container based upon a comparison of the detected data relating to the motor operation of a circulating pump and to the heat increase in the dishwasher with stored target values;
- and
- adapting the washing programme according to the quantity value of dishes that is set via the step of setting a quantity value for the quantity of dishes in the washing container.
A dishwasher, comprising:
- a washing container for retaining therein a quantity of dishes;
- a heating device for heating a rinsing solution comprising a quantity of water;
- at least one spray device for directing the rinsing solution that has been heated onto the dishes;
- a circulating pump for circulating the rinsing solution through the heating device after the rinsing solution has been directed onto the dishes such that heat is imparted by the heating device to the rinsing solution, whereupon the now-further heated rinsing solution can again be directed by the at least one spray device onto the dishes, the rinsing solution undergoing cooling upon contact with the dishes as a result of a heat exchange from the relatively hotter rinsing solution to the relatively cooler dishes, and the dishwasher operating to provide a heat increase to ensure that the heat imparted to the rinsing solution brings the rinsing solution to a desired temperature before the rinsing solution is directed by the at least one spray device onto the dishes;
- a motor operation sensor for sensing data relating to the motor operation of the circulating pump during at least one of a pre-washing phase and a heating phase;
- a heat increase sensor for sensing data relating to the heat increase in the dishwasher during at least one of a pre-washing phase and a heating phase;
- and
- a programme control for comparing sensed motor operation sensor and heat increase data with stored target values, for setting a quantity value for the quantity of dishes in the washing container based upon a comparison of sensed motor operation sensor and heat increase data with stored target values, and for adapting a washing programme according to the thus-set dishes quantity value.
