Definitions
- the present invention relates to a dishwasher the energy consumption and washing performance of which is optimized.
- German Patent Application No. DE19734264 a dishwasher is disclosed wherein energy consumption is decreased and the program time is shortened.
- the aim of the present invention is the realization of a dishwasher, the energy consumption and the washing performance of which are improved.
- the dishwasher realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a body, a washing tub that is disposed into the body and wherein the washing process is performed, a circulation line that supplies water to the washing tub, a circulation pump that enables water to be pumped from the circulation line to the washing tub, a temperature sensor that is disposed on the body and that measures the temperature of the mains water and the temperature of the wash water, a heater that heats the mains water, and a control unit that controls the operation of the heater, the circulation pump and the temperature sensor in accordance with the program steps predetermined by the manufacturer.
- the control unit regulates the circulation time in the main washing step by comparing the measured mains water temperature with the target wash water temperature value.
- the control unit changes the circulation time during the main washing process depending on the circulation time during the heating operation.
- the circulation time that gets shorter in the heating step due to high mains water temperature is compensated in the main washing step. Thus, the same washing performance is attained in every situation independently from the mains water temperature.
- control unit prolongs the circulation time realized in the main washing step by an additional time predetermined by the manufacturer if the circulation time realized in the heating step is smaller than the heating circulation time predetermined by the manufacturer.
- the washing process is prevented from ending before the objects in the dishwasher are entirely cleaned.
- control unit decreases the main washing circulation time prerecorded for the main washing step in the control unit by an additional time predetermined by the manufacturer if the circulation time realized in the heating step is greater than the heating circulation time predetermined by the manufacturer.
- energy consumption is prevented from increasing due to excessive circulation and the total program time is decreased.
- control unit does not change the predetermined main washing circulation time and the heating circulation time if the measured mains water temperature is equal to the target wash water temperature value.
- control unit deactivates the heater and operates the circulation time of the heating step in the washing step if the measured mains water temperature is greater than the target wash water temperature value. Consequently, the energy consumption is decreased.
- control unit operates the heater for a longer time and/or at a higher power value if the measured mains water temperature is smaller than the target wash water temperature value.
- Figure 1 – is the perspective view of a dishwasher.
- T tw a target wash water temperature value predetermined by the manufacturer
- ( ⁇ T) temperature difference between the target wash water temperature value (T tw ) and the measured mains water temperature (T rt )
- the dishwasher (1) of the present invention comprises,
- the control unit (8) of the present invention in the memory of which a heating circulation time (t ch ) for the heating step predetermined by the manufacturer and a main washing circulation time (t cw ) for the main washing step predetermined by the manufacturer are recorded, changes the main washing circulation time (t cw ) by comparing the measured wash water temperature (T rw ) and a target wash water temperature value (T tw ) predetermined by the manufacturer.
- the control unit (8) prolongs the main washing circulation time (t cw ) depending on the measured mains water temperature (T rt ) or deactivates the circulation pump (7) before the main washing circulation time (t cw ) is completed. Thus, deviations in the cleaning performance of the dishwasher (1) are decreased without changing the energy consumption.
- the control unit (8) prolongs the main washing circulation time (t cw ) by an additional time (t d ) predetermined by the manufacturer if the measured mains water temperature (T rt ) is greater than the target wash water temperature value (T tw ).
- the additional time (t d ) is implemented depending on the temperature difference interval ( ⁇ T 1 , ⁇ T 2 , ⁇ T 3 ,.7) that is prerecorded in the control unit (8) by the manufacturer and that corresponds to the temperature difference ( ⁇ T) between the target wash water temperature value (T tw ) and the measured mains water temperature (T rt ).
- the circulation time that decreases due to shortened heating process time is prolonged by additional times that are prerecorded in the control unit (8) by the manufacturer.
- the control unit (8) stops the circulation pump (7) before the main washing circulation time (t cw ) is completed if the measured mains water temperature (T rt ) is smaller than the target main washing temperature value (T tw ).
- the circulation time that continues in the main washing step is kept short.
- the cleansed dirt is prevented from adhering again on the cleaned items due to excessive circulation and the program time is prevented from prolonging.
- control unit (8) operates the circulation pump (7) during the main washing circulation time (t cw ) if the measured mains water temperature (T rt ) is equal to the target wash water temperature value (T tw ).
- T cw main washing circulation time
- control unit (8) deactivates the heater (5) if measured mains water temperature (T rt ) is greater than the target wash water temperature value (T tw ). Consequently, energy consumption is decreased and program times are shortened by skipping the heating step.
- control unit (8) operates the heater (5) for a longer time if the measured mains water temperature (T rt ) is smaller than the target wash water temperature value (T tw ).
- control unit (8) operates the heater (5) at a higher power value.
- a dishwasher (1) is realized, the energy consumption and washing performance of which are independent from the temperature of the used mains water.
