Der Zwischenspeicherschritt kann je nach Umweltbedingungen abgeschaltet werden, so dass ein Kühleffekt auf die Umgebung entsteht, beispielsweise im Sommer. After balancing the temperature of the waste water tank 125 with the environment, the cached waste water 129 can be discharged. Inlet and outlet of the wash liquor 107 or the waste water into the waste water tank 125 is controlled by means of an outlet valve 135. The intermediate storage step can be switched off depending on the environmental conditions, so that a cooling effect on the environment arises, for example in summer.
Die Koordination von Energiegewinnung, Transfer und Wassermanagement kann beispielsweise die folgenden Schritte umfassen. Zunächst findet eine Füllung des Coordination of power generation, transfer and water management may include, for example, the following steps. First, find a filling of the
Laugenbehälters 105 mit Leitungswasser statt. Anschließend erfolgt eine Füllung desLye tank 105 with tap water instead. Subsequently, a filling of the
Spülwasserbehälters 101 als Vorratsbehälter mit Leitungswasser. Danach geschieht eine Erwärmung des Wassers im Laugenbehälter 105 über den Thermogenerator 109 durch Wärmeenergie aus dem Wasser des Spülwasserbehälters 101. Danach erfolgt ein Ausgleich der Wärmeenergie des Wassers im Spülwasserbehälter 101 durch die Umgebungsluft über den Lüfter 1 13. Schließlich wird ein Waschprozess mittels der im Laugenbehälter 105 vorhandenen Waschlauge 107 durchgeführt. Anschließend wird die Waschlauge 107 in den Abwasserbehälter 125 zur teilweisen Rückgabe der Wärmeenergie an die Umgebung abgepumpt und in dem Abwasserbehälter 125 temporär Rinse water tank 101 as a reservoir with tap water. This is followed by a heating of the water in the tub 105 via the thermal generator 109 by thermal energy from the water of Spülwasserbehälters 101. Thereafter, a compensation of the heat energy of the water in Spülwasserbehälter 101 by the ambient air through the fan 1 13. Finally, a washing process using the in the tub 105 existing wash liquor 107 performed. Subsequently, the wash liquor 107 is pumped into the waste water tank 125 for partially returning the heat energy to the environment and temporarily in the waste water tank 125
zwischengespeichert, bevor die Waschlauge als Abwasser abgelassen wird. Zum besseren Übertragen von Wärme von dem Abwasser 129 an die Umgebung umfasst der cached before the wash liquor is discharged as waste water. For better transfer of heat from the waste water 129 to the environment comprises
Abwasserbehälter 125 Wärmeübertragungsrippen 127. Sewage tank 125 heat transfer ribs 127.
Danach wird mit kaltem Wasser aus dem Spülwasserbehälter 101 gespült. Sollte der Spülwasserbehälter 101 entleert sein, wird der Laugenbehälter 105 mit zufließendem Leitungswasser gespült. Das Abwasser aus dem Abwasserbehälter 125 wird nach Thereafter, rinsed with cold water from the rinse tank 101. If the rinse water tank 101 is emptied, the tub 105 is rinsed with inflowing tap water. The waste water from the waste water tank 125 is after
Abkühlung oder spätestens vor Beenden des Waschganges über ein Ventil 139 abgelassen. Durch die Zwischenspeicherung in dem Abwasserbehälter 125 wird die in dem Abwasser 129 vorhandene Wärme größtenteils an die Umgebung zurückgegeben. Durch das Haushaltgerät wird eine deutliche Verringerung der durch das Haushaltsgerät im Waschprozess aufgenommenen Elektroenergie erzielt. Durch den Wegfall eines Cooling or at the latest before ending the wash cycle via a valve 139 drained. Due to the intermediate storage in the waste water tank 125, the heat present in the waste water 129 is largely returned to the environment. The household appliance achieves a significant reduction in the electrical energy consumed by the domestic appliance in the washing process. By eliminating one
Rohrheizkörpers ist eine Vereinfachung der Laugenbehälterkonstruktion möglich. Zudem ergibt sich eine Einsparung beim Wasserverbrauch. Es erfolgt eine doppelte Nutzung des im Spülwasserbehälter 101 befindlichen und bereits zur Wärmeentnahme verwendeten Tubular heater is a simplification of the tub construction possible. In addition, there is a saving in water consumption. There is a double use of located in the rinse tank 101 and already used for heat extraction
Leitungswassers zur Vermeidung eines Mehrverbrauches. Tap water to avoid overconsumption.
