Solar- WaschmaschineSolar washing machine
Beschreibung:Description:
Gegenstand der Erfindung ist eine mit Solarenergie betriebene Waschmaschine einfachster Bauart.The invention relates to a washing machine of the simplest type operated with solar energy.
Waschmaschinen, deren elektrischer Energiebedarf durch ganz oder teilweise durch von einer Solarzelle erzeugte elektrische Energie gedeckt wird, sind beispielsweise aus der Offenlegungschrift DE 19708861 bekannt. Durch die Nervvendung photovoltaisch erzeugter elektrischer Energie soll die Entnahme elektrischer Energie aus dem Netz vermindert oder vermieden werden. Es ist ferner aus der Offenlegungsschrift DE 4304382 bekannt, zur Einsparung von Trinkwasser ein zusätzliches Wasserversorgungssystem zu verwenden, mit dem Brauchwasser, Brauchlauge, Brunnen- oder Regenwasser genutzt werden kann.Washing machines whose electrical energy requirements are covered in whole or in part by electrical energy generated by a solar cell are known, for example, from published patent application DE 19708861. The use of photovoltaically generated electrical energy is intended to reduce or avoid the removal of electrical energy from the grid. It is also known from published patent application DE 4304382 to use an additional water supply system to save drinking water, with which process water, process water, well water or rainwater can be used.
Die bekannten Systeme dienen dem Bedürnis, durch Einsparungen von Energie Umweltbelastungen zu vermeiden. Diese Systeme setzen jedoch voraus, daß die benötigte, einzusparende Energie aus modernen, privaten oder öffentlichen Strom - und Wasseversorgungsnetzen grundsätzlich zur Verfügung stehen. In Gegenden der Welt, in denen dies nicht der Fall ist, ist es zwar wünschenswert aus hygienischen Gründen auch Waschmaschinen verwenden zu können. Dies scheitert jedoch häufig daran, daß die Voraussetzungen für die Verwendung hoch technisierter Waschmaschinen, nämlich die Versorgung derartiger Waschmaschinen mit elektrischer Energie und Druckwasser nicht gewährleistet ist, obwohl zumindest in Ländern mit hoher Sonneneinstrahlung und ausreichender Wasservorkommen dies wünschenswert ist.The known systems serve the need to avoid environmental pollution by saving energy. However, these systems require that the energy to be saved from modern, private or public electricity and water supply networks is basically available. In areas of the world where this is not the case, it is desirable to be able to use washing machines for hygienic reasons. However, this often fails because the prerequisites for the use of high-tech washing machines, namely the supply of such washing machines with electrical energy and pressurized water, are not guaranteed, although this is desirable at least in countries with high levels of sunshine and sufficient water resources.
Ein weiterer Grund für den Mangel der Verwendung von Maschinen zum hygienischen Waschen von Wäsche und Kleidung ist in dem meist bescheidenen technischen Ausbildungsgrad der Bevölkerung in derartigen Ländern und dem bescheidenen Einkommen zu sehen, das die Verwendung moderner Waschmaschinen regelmäßig nicht erlaubt.Another reason for the lack of the use of machines for the hygienic washing of laundry and clothing can be seen in the mostly modest level of technical education of the population in such countries and the modest income, which regularly does not allow the use of modern washing machines.
Aufgabe der Erfindung ist es daher, zur Verbesserung hygienischer Verhältnisse in armen und unterentwickelten Ländern eine Vorrichtung zum Waschen von Wäsche und Kleidung zu finden, die den energetischen Verhältnissen, den technischen Fähigkeiten und den finanziellen Rahmenbedingungen entsprechen.The object of the invention is therefore to improve the hygienic conditions in poor and underdeveloped countries, a device for washing Finding laundry and clothing that correspond to the energetic conditions, the technical skills and the financial framework.
Die Lösung der Aufgabe wird in einer Waschmaschine einfachster Bauart unter Verwendung der Solarenergie zur Erzeugung elektrischer Energie zum Antrieb der Maschine und zur Erzeugung von Heißwasser gesehen.The solution to the problem is seen in a washing machine of the simplest type using solar energy to generate electrical energy to drive the machine and to produce hot water.
Erfindungsgemäß besteht die Waschmaschine aus einem Gehäuse mit einer darin gelagerten gelochten Waschtrommel mit einem Beladezugang, die durch einen im Gehäuse angeordneten Elektromotor angetrieben wird, einer mit Ventilen versehenen Wasserzu- und Ableitung sowie einem Sonnenkollektor zur Umwandlung von Sonnenenergie in photovoltaischen Zellen zu elektrischer Energie zum Laden eines Akkus, der den Elektromotor versorgt, sowie zur Umwandlung der Solarenergie in Wärmeenergie zum Aufheizen von in einem Röhrensystem zirkulierendem Wasser.According to the invention, the washing machine consists of a housing with a perforated washing drum mounted therein with a loading access, which is driven by an electric motor arranged in the housing, a valve-provided water inlet and outlet and a solar collector for converting solar energy in photovoltaic cells into electrical energy for charging a battery that supplies the electric motor, and for converting solar energy into thermal energy for heating water circulating in a tube system.
Vorzugsweise ist femer in dem Gehäuse eine einfache Steuereinrichtung angeordnet, die den Antrieb des Elektromotors nur dann steuert, wenn der Akku für einen oder mehrere Wasch und Spülvorgänge ausreichende Ladung aufweißt und ein für einen oder mehrere Wasch- und Spülvorgänge ausreichender Wasservorrat mit einer Temperatur von 45 bis 60 Grad Celsius in dem Röhrensystem des Sonnenkollektors vorhanden ist.Furthermore, a simple control device is preferably arranged in the housing, which controls the drive of the electric motor only when the battery has sufficient charge for one or more washing and rinsing processes and a water supply with a temperature of 45 sufficient for one or more washing and rinsing processes up to 60 degrees Celsius in the tube system of the solar collector.
Femer ist es vorteilhaft, an der Gehäuseöffnung einen Schalter anzuordnen, über den die Steuereinrichtung erst dann den Wasservorgang einschaltet, wenn das Gehäuse verschlossen ist, um unnötige Waschvorgänge zu vermeiden, wenn die Trommel nicht mit Waschgut beschickt ist.It is also advantageous to arrange a switch at the housing opening, via which the control device only switches on the water process when the housing is closed, in order to avoid unnecessary washing processes when the drum is not loaded with laundry.
Es ist weiterhin von Vorteil, für die Öffnung und Schließung der Ventile des Wasserzu- und Ablaufes elektromagnetische, von der Steuereinrichtung gesteuerte Ventile vorzusehen, um das teschnische Verständnis des Benutzers möglichst wenig in Anspruch zu nehmen.It is also advantageous to provide electromagnetic valves controlled by the control device for the opening and closing of the water inlet and outlet valves in order to minimize the technical understanding of the user.
Die Kollektoren zur Umwandlung der Sonnenenergie in elektrische bzw. Wärmeenergie sind vorzugsweise in einem gemeinsamen Rahmenelement angeordnet, das oberhalb der Waschmaschine mit dem Gehäuse integriert oder von diesem getrennt, beispielsweise auf dem Dach eines Gebäudes angeordnet ist.The collectors for converting the solar energy into electrical or thermal energy are preferably arranged in a common frame element which integrates with the housing above the washing machine or from this is arranged separately, for example on the roof of a building.
Der Gehäusezugang ist vorzugsweise auf dem Deckel und der Waschtrommelzugang auf dem Umfang der Trommel angeordnet. Damit wird eine kostspielige einseitige Lagerung der Trommel und eine technisch aufwendige Abdichtung der Gehäusefront vermieden.The housing access is preferably arranged on the lid and the washing drum access on the circumference of the drum. This avoids costly one-sided storage of the drum and a technically complex sealing of the front of the housing.
Zur weiteren Erläuterung der Erfindung wird auf ein in der beigefügten Zeichnung dargestelltes Ausfiihrungsbeispiel verwiesen.To further explain the invention, reference is made to an exemplary embodiment shown in the accompanying drawing.
