Washing machine, in which a radiation source having a bactericidal effect is arranged inside or outside. The lamp can be mounted in a watertight manner in the washing machine or in front of the inspection glass, for example of a domestic washing machine.

Description

Bezeichnungdescription

Bei der vorliegenden Erfindung handelt es sich um eine Waschmaschine mit eingebauter Desinfektionseinrichtung. Die Desinfektionseinrichtung beruht auf dem Prinzip der Bestrahlung mit vorzugsweise ultraviolettem Licht.The present invention is a washing machine with built-in disinfection device. The disinfection device is based on the principle of irradiation with preferably ultraviolet light.

Stand der Technik Bekaiint sind Waschmaschinen der verschiedensten Art wie z.B Maschinen die von vorne bestückt werden und meist Schaugläser besitzen und Maschinen die von oben bestückt werden; hierbei ist die Wäsche während des Waschvorganges nicht zu sehen. Aufgabe einer Waschmaschine ist,es, Wäsche von Verunreinigungen zu säubern, einmal in optischer Hinsicht, zum anderen in hygienischer (desinfizierender) Hinsicht. Die optische Sauberkeit der Wäsche ist bei vielen Wnschestiicken bereits bei Waschgangen von z.fl.' 600 C erreicht. Diese Temperatur reicht nicht aus für die Desinfektion. Beim "Kochwaschgang" wird meist bei 950 C gewaschen, wobei diese Tempçratur eine Desinfektion auch nur unvollkommen ermöglicht1 da kein echtes Kochen (über 100° C) der Wäsche.durchgeführt wird. Allerdings besteht gegenüber der z.B.. 600 C Wäsche ein ganz erheblich höherer Energiebedarf, ca. doppelt so hoch unter gleichen Voraussetzungen.State of the art Washing machines of the most varied are known Type such as machines that are loaded from the front and usually have sight glasses and machines that are loaded from above; here the laundry is during the washing process not to see. A washing machine's job is to wash off debris to clean, on the one hand from an optical point of view, on the other hand in a more hygienic (disinfecting) Respect. The optical cleanliness of the laundry is already good for many items for wash cycles of z.fl. ' 600 C reached. This temperature is not enough for the disinfection. The "boil wash" is usually washed at 950 C, with this Temperature does not allow disinfection, even if it is incomplete1, since there is no real cooking (over 100 ° C) of the laundry. However, compared to e.g. 600 C laundry a considerably higher energy requirement, approx. Twice as high under same conditions.

Aufgabe der Erfindung ist es, die Desinfektion der Wäsche während des Waschvorganges von unter 950 C ohne chemische Mittel zu ermöglichen. Beim Kochwaschgang von 950 C soll die Desinfektion wesentlich verbessert werden. Dabei kann, wenn Desinfektion gewünscht wird, diese auch bei Schonwaschgängen (z.B. 3001 400, 600 C) vorgenommen werden mit einem dann hohen Energiespareffekt gegenüber dem Kochwasch gang.The object of the invention is to disinfect the laundry during the washing process of below 950 C without chemical agents. In the boil cycle from 950 C the disinfection should be significantly improved. Doing this if disinfection If you wish, this can also be carried out on gentle cycles (e.g. 3001 400, 600 C) are then with a high energy-saving effect compared to the boil wash cycle.

Die Aufgabe der Erfindung wird gelöst durch eine UV-Licht emittierende Strahlungsquelle, welche während der Waschprozesse bzw.The object of the invention is achieved by a UV light emitting Radiation source that occurs during the washing process or

Trockenprozesse das Wäschegut und/oder das Waschwasser bestrahlt. Dabei wird eine keimtötende Wirkung erreicht.Drying processes irradiate the laundry and / or the washing water. A germicidal effect is achieved.

Bei Waschmaschinen die von vorne bestückt werden, besteht die Beschickungstür (6) zumeist aus rund geformtem, teilweise doppelwandigem llohlglas, wodurch das Kochgut während des Waschvorganges beobachtet werden kann. Dieser Typus ist beisp#eihaft in der Prinzipskizze i dargestellt. Zweckmässigerweise wird, innerhalb dieses Glases (2) die UV-emittierende Strahlungsquelle (1) angeordnet, welche während des gesamten Arbeitsprozesses das Waschwasser und das Waschgut bestrahlt. In Richtung auf die Innenseite der Waschmaschine wird dabei UV-Licht durchlässiges Glas oder ein sonstiger W-durchlässiger Kunststoff verwendet. Nach außen wird die direkte UV-Licht-Abstrahlung verhindert, z.B. durch Verwendung von entsprechendem UV-undurchlässigm - Material, Metallisieren, Bedampfen oder mittels eines kleinen Reflektors (4) der unmittelbar hinter der Lampe angeordnet-wird.For washing machines that are loaded from the front, there is a loading door (6) mostly made of round shaped, partly double-walled llohlglas, whereby the Food can be observed during the washing process. This type is exemplary shown in the schematic diagram i. Appropriately, within this glass (2) the UV-emitting radiation source (1) arranged, which throughout the Work process irradiates the wash water and the items to be washed. Towards the The inside of the washing machine becomes UV-light permeable glass or some other W-permeable plastic used. The direct UV light radiation is directed outwards prevented, e.g. by using appropriate UV-impermeable material, Metallization, vapor deposition or by means of a small reflector (4) directly is arranged behind the lamp.

Bei Waschmaschinen welche kein Schauglas haben, ist es nicht möglich, das Waschgut direkt zu bestrahlen. In diesem Fall ist nur die Bestrahlung und Desinfektion des Waschwassers während des Arbeitsprozesses möglich; dabei wird die Strahlungsquelle in der Waschmaschine außerhalb der Waschtrommel (3) angeordnet.With washing machines that do not have a sight glass, it is not possible to irradiate the laundry directly. In this case there is only irradiation and disinfection of the washing water possible during the work process; thereby the radiation source arranged in the washing machine outside the washing drum (3).

Auch hier wird eine desinfizierende Wirkung erzielt, die aber geringer ist als bei den Waschmaschinen mit Schauglas. Notwendig ist in dies<'m Lag je ijatürlich auch eine wasserdichte,.UV-durchlässige Umhüllung für die Lampe.A disinfecting effect is also achieved here, but less than with washing machines with a sight glass. In this <'m lag ever is necessary Of course there is also a waterproof, UV-permeable cover for the lamp.

Als weiteren Effekt zeigt sich im Falle der Desinfektion mit UV-Licht während des Arbeitsprozesses, daß auch das Abwasser desinfiziert wird und somit die Kläranlagen nicht mit zusätzlichen schädlichen Keimen belastet werden. Neben dem Einbau in Waschmaschinen ist es auch möglich, eine Anordnung der beschriebenen oder ähnlichen Art bei anderen Prozessen zur Desinfektion einzusetzen. Beispielsweise bei Schleudern, Trockenschleudern, Wäschetrocknern, Spülmaschinen. Weitere Einsatzgebiete sind denkbar, sollen aber hier im einzelnen nicht ausgeführt werden.Another effect can be seen in the case of disinfection with UV light during the work process that the wastewater is also disinfected and thus the sewage treatment plants do not have additional harmful germs will. In addition to installation in washing machines, it is also possible to arrange the described or similar type in other processes for disinfection. For example, with spin dryers, tumble dryers, dishwashers. Other areas of application are conceivable, but will not be discussed in detail here will.
