Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Entfernung von Eis, insbesondere für den Einsatz in Tiefkühlräumen.The present invention relates to a device for removing ice, in particular for use in freezers.

In Tiefkühlräumen wird bekanntermaßen durch Kondensation Eisbildung entstehen. Eine Reinigung mit Wasserdampf ist aufgrund von Schädigung der Dichtungen (Sandwichelemente) nicht möglich. Der Wasserdampf, würde zudem im laufenden Betrieb (herunter gekühlter Raum) zu direkter Kondensation führen und somit eine weitere Eisbildung erzeugen.In freezer rooms ice formation is known to be due to condensation. Cleaning with water vapor is not possible due to damage to the seals (sandwich elements). The water vapor, would also lead during operation (cooled down space) to direct condensation and thus generate further ice formation.

Aktuelle Möglichkeiten sind die Enteisung mit chemischen Reinigungsmitteln oder die Erhöhung der Raumtemperatur, um eine konventionelle Reinigung durchzuführen. Diese Maßnahme ist aber energetisch ungünstig und führt zu einen zeitlichen Ausfall des Tiefkühlraumes.Current options include de-icing with chemical cleaning agents or increasing the room temperature to perform a conventional cleaning. This measure is energetically unfavorable and leads to a temporal failure of the freezer compartment.

Die GB 2 338 053 A offenbart eine Enteisungsvorrichtung mit einer Wärmequelle und Absaugmitteln. Die Wärmequelle ist als Heizelement oder Heißluftgebläse ausgebildet.The GB 2 338 053 A discloses a deicing device with a heat source and suction means. The heat source is designed as a heating element or hot air blower.

Die US 3 439 374 A offenbart eine Vorrichtung zur Entfernung von Eis gemäß dem Oberbegriff von Anspruch 1 und beschreibt eine Reinigungsvorrichtung, bei der ein Reinigungsfluid erhitzt und dann im erhitzten Zustand auf eine zu reinigende Oberfläche aufgebracht wird. Die Absaugung des Fluids und gelöster Verunreinigungen erfolgt über einen Absaugkanal.The US 3 439 374 A discloses a device for removing ice according to the preamble of claim 1 and describes a cleaning device in which a cleaning fluid is heated and then applied in a heated state to a surface to be cleaned. The suction of the fluid and dissolved impurities via a suction channel.

Das der vorliegenden Erfindung zugrunde liegende Problem ist die Schaffung einer Vorrichtung der eingangs genannten Art, die effektiver ausgebildet ist.The problem underlying the present invention is the provision of a device of the type mentioned, which is designed to be more effective.

Dies wird erfindungsgemäß durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 erreicht. Die Unteransprüche betreffen bevorzugte Ausgestaltungen der Erfindung.This is inventively achieved by a device having the features of claim 1. The subclaims relate to preferred embodiments of the invention.

Die Vorrichtung umfasst Mittel zur Erzeugung von Wärme und Mittel zur Absaugung. Die Mittel zur Erzeugung von Wärme umfassen dabei ein Heizelement. Die Mittel zur Absaugung können beispielsweise Luft und Wasserdampf absaugen und umfassen einen über den Boden bewegbaren Saugkopf. Das Heizelement ist in dem Saugkopf angeordnet. Im Allgemeinen sind die Mittel zur Absaugung dazu ausgebildet, gasförmige Stoffe abzusaugen. Es ist auch möglich, dass die Mittel zur Absaugung dazu ausgebildet sind, gasförmige und flüssige Stoffe abzusaugen.The device comprises means for generating heat and means for suction. The means for generating heat comprise a heating element. The suction means may, for example, extract air and water vapor and comprise a suction head movable over the floor. The heating element is arranged in the suction head. In general, the means for suction are designed to suck gaseous substances. It is also possible that the means for suction are designed to suck gaseous and liquid substances.

Die Mittel zur Absaugung können Eiskristalle und/oder entstehenden Wasserdampf und/oder entstehende warme Luft absaugen. Die entstehende warme Luft kann beispielsweise die Luft sein, die durch die Mittel zur Erzeugung der Wärme erzeugt wurde. Die Mittel zur Erzeugung von Wärme weisen mehrere Durchlässe auf. Bei der Absaugung umströmen die Eiskristalle, der Wasserdampf und/oder die erwärmte Luft die Mittel zur Erzeugung von Wärme und strömen durch die Durchlässe.The means for suction can suck ice crystals and / or resulting water vapor and / or resulting warm air. The resulting warm air may be, for example, the air generated by the means for generating the heat. The means for generating heat have multiple passages. During the suction, the ice crystals, the water vapor and / or the heated air flow around the means for generating heat and flow through the passages.

Es ist somit möglich mit
der Vorrichtung nur einen begrenzten Bereich einer Wand, einer Decke oder eines Bodens eines Kühlraums gezielt zu erwärmen und die Wärme und den entstehenden Wasserdampf abzusaugen. Daher kann auf den Einsatz chemischer Mittel verzichtet werden und es muss nicht der gesamte Kühlraum erwärmt werden.It is thus possible with
the device to heat only a limited area of a wall, a ceiling or a floor of a cold room targeted and to suck the heat and the resulting water vapor. Therefore, can be dispensed with the use of chemical means and it does not heat the entire refrigerator.

Die Idee ist es also, ohne chemische Reinigungsmittel zu arbeiten, d.h. im laufendem Betrieb der Tiefkühlung - ohne die Temperaturen anheben zu müssen - eine Reinigung durchführen zu können.So the idea is to work without chemical cleaning agents, i. during the operation of the deep-freezing - without having to raise the temperatures - to be able to carry out a cleaning.

Die Möglichkeit für eine solche Maßnahme ist durch eine flächenbezogene Erwärmung mit gleichzeitiger Absaugung gegeben. Durch das gezielte und punktuelle Erwärmen der zu reinigenden Oberfläche ist eine Kontrolle über die übertragene Temperatur auf die unter der Eisschicht liegende Oberfläche der Tiefkühlzelle möglich. Dadurch ist gewährleistet, dass keine Schäden an der Boden- oder Wandfläche (Dichtungen) entstehen. Je nach zu reinigender Fläche ist es ebenso möglich, durch die aufgebrachte Temperatur eine Desinfektion dieser Fläche durchzuführen.The possibility for such a measure is given by a surface-related heating with simultaneous suction. The targeted and selective heating of the surface to be cleaned, a control of the transmitted temperature on the lying below the ice layer surface of the freezer cell is possible. This ensures that no damage to the floor or wall surface (seals) arise. Depending on the area to be cleaned, it is also possible to carry out a disinfection of this area by the applied temperature.

Die Kondensation der in der warmen Luft gebundenen Feuchtigkeit wird durch eine direkte Absaugung der entstehenden Wärme verhindert. Dabei muss beachtet werden, dass diese Wärme aus der Tiefkühlzelle selber geführt wird. Dies kann durch vorgesehene Wandanschlüsse ohne weiteres technisch umgesetzt werden, so dass außerhalb des Tiefkühlraumes der Absauger steht.The condensation of the moisture bound in the warm air is prevented by a direct suction of the resulting heat. It should be noted that this heat is conducted from the freezer cell itself. This can be implemented technically by provided wall connections, so that stands outside the freezer compartment of the extractor.

Die flächenbezogene Erwärmung kann, je nach Einsatzgebiet, mit herkömmlichen Heizstäben, Infrarotstrahlern oder Warmluftströmung erfolgen.The surface-related heating can, depending on the application, be done with conventional heating rods, infrared radiators or hot air flow.

Nach einer Ausführungsform der Erfindung können die Mittel zur Absaugung einen Saugkopf und/oder einen Absaugschlauch und/oder einen Motor mit Ventilator umfassen. Der Saugkopf kann durch einen Benutzer über eine zu enteisende Fläche geführt werden. Der Saugkopf ist also über eine Fläche führbar.According to one embodiment of the invention, the means for suction a suction head and / or a suction hose and / or include a motor with fan. The suction head can be guided by a user over a surface to be deiced. The suction head is thus feasible over an area.

Nach einer Ausführungsform der Erfindung kann die Vorrichtung mechanische Bearbeitungsmittel wie beispielsweise Bürsten umfassen. Die mechanischen Bearbeitungsmittel können beispielsweise so angeordnet sein, dass Verunreinigungen von der zu enteisenden Oberfläche entfernt werden. Vorteilhafterweise vermindern die mechanischen Bearbeitungsmittel das Risiko, dass Verunreinigungen in die Mittel zur Absaugung gelangen. Hierfür können die mechanischen Bearbeitungsmittel als Bürsten ausgebildet sein, die dazu ausgebildet sind, über die zu enteisende Oberfläche geführt zu werden. Die mechanischen Bearbeitungsmittel können beispielsweise im Saugkopf angeordnet sein.According to one embodiment of the invention, the device may comprise mechanical processing means such as brushes. For example, the mechanical processing means may be arranged to remove contaminants from the surface to be deiced. Advantageously, the mechanical processing means reduce the risk of contaminants entering the suction means. For this purpose, the mechanical processing means may be formed as brushes, which are adapted to be guided over the surface to be deiced. The mechanical processing means may be arranged, for example, in the suction head.

Für eine zusätzliche Reinigungsleistung ist es möglich, optional in den Saugkopf Bürsten einzubauen. Weiterhin kann die Vorrichtung UV-Bestrahlungsmittel für eine zusätzliche Reinigungswirkung durch Bestrahlung mit einer ultravioletten Strahlung umfassen. Die UV-Bestrahlungsmittel können beispielsweise im Saugkopf angeordnet sein.For additional cleaning performance, it is possible to optionally install brushes in the suction head. Furthermore, the device may comprise UV irradiation means for an additional cleaning effect by irradiation with an ultraviolet radiation. The UV irradiation means may be arranged in the suction head, for example.

Es ist auch möglich, dass die Mittel zur Absaugung einen Anschluss für einen Schlauch umfassen. So lässt sich die erzeugte Wärme durch den angeschlossenen Schlauch absaugen. Der Schlauch kann beispielsweise an einen Wandanschluss angeschlossen werden, sodass die Wärme aus dem Tiefkühlraum geführt wird.It is also possible that the suction means comprise a connection for a hose. This allows the generated heat to be sucked through the connected hose. The hose can For example, be connected to a wall connection, so that the heat is conducted from the freezer compartment.

Nach einer Ausführungsform der Erfindung kann die Vorrichtung Filtermittel umfassen. Die Filtermittel können beispielsweise siebförmig ausgebildet sein. Die Filtermittel können für eine Filterung der durch die Mittel zur Absaugung abgesaugten Stoffe ausgebildet sein. So wird beispielsweise verhindert, dass Verunreinigungen auf dem Boden oder an der Wand des Tiefkühlraums Bauteile die Vorrichtung verstopfen.According to one embodiment of the invention, the device may comprise filter means. The filter means may be formed, for example, sieve-shaped. The filter means may be designed for filtering the suctioned by the means for suction substances. For example, it prevents impurities on the floor or on the wall of the freezer compartment components from clogging the device.

Hierfür kann vorgesehen sein, dass die Filtermittel in und/oder an dem Saugkopf angeordnet sind.For this purpose, it can be provided that the filter means are arranged in and / or on the suction head.

Die Vorrichtung kann Steuerungsmittel umfasst, die dazu ausgebildet sind, eine Leistung der Mittel zur Erzeugung von Wärme zu steuern. So kann die erzeugte Wärme gezielt an örtliche Gegebenheiten angepasst werden. Mit einer höheren Leistung lässt sich beispielsweise eine schnellere Reinigung erreichen. Mit einer besonders hohen Leistung kann eine zusätzliche Desinfektion erfolgen. Eine relativ niedrige Leistung kann energiesparend sein.The apparatus may comprise control means adapted to control a power of the means for generating heat. This allows the generated heat to be specifically adapted to local conditions. For example, faster performance can be achieved with higher performance. With a particularly high performance, an additional disinfection can take place. A relatively low power can be energy efficient.

Nach einer Ausführungsform der Erfindung können die Mittel zur Absaugung einen Behälter umfassen, der dazu ausgebildet ist, Luft, Wasser, Wasserdampf und/oder Eiskristalle aufzunehmen. Dieser Behälter kann beispielsweise über einen Schlauch am Saugkopf angeschlossen sein, sodass die erzeugte Wärme, die Luft, das Wasser, der Wasserdampf und/oder die Eiskristalle durch den Schlauch in den Behälter abgesaugt werden.According to one embodiment of the invention, the suction means may comprise a container adapted to receive air, water, water vapor and / or ice crystals. This container may for example be connected via a hose on the suction head, so that the heat generated, the air, the water, the water vapor and / or the ice crystals are sucked through the hose into the container.

Die in den Figuren dargestellte Vorrichtung umfasst einen von einem Benutzer über einen Boden 4 bewegbaren Saugkopf 1 (siehe Fig. 1 und Fig. 2). Der Boden 4 ist mit einer Eisschicht 3 bedeckt. Der Saugkopf 1 ist über einen vorzugsweise doppelwandigen Absaugschlauch 2 mit einem Nasssauger 10 verbunden (siehe Fig. 2). Der in Fig. 2 dargestellte Nasssauger 10 ist für einen elektrische Spannung von 230V ausgebildet und weist eine Leistung von 1,5kW auf. Es ist auch möglich, einen Nasssauger mit einer anderen Leistung zu verwenden. Es ist auch möglich, dass der Nasssauger für eine andere Spannung wie beispielsweise 110V ausgebildet ist.The apparatus shown in the figures comprises a suction head 1 which can be moved by a user via a floor 4 (see FIG Fig. 1 and Fig. 2 ). The bottom 4 is covered with an ice layer 3. The suction head 1 is connected via a preferably double-walled suction hose 2 with a wet vacuum cleaner 10 (see Fig. 2 ). The in Fig. 2 shown wet vacuum 10 is designed for a voltage of 230V and has a power of 1.5 kW. It is also possible to use a wet vacuum with a different power. It is also possible that the wet vacuum is designed for a different voltage such as 110V.

Außerdem ist die Vorrichtung 1 an eine elektrische Energiequelle angeschlossen. In Fig. 2 ist dargestellt, dass diese eine Spannung von 230V und eine Leistung von 1kW aufweist. Es können jedoch auch andere elektrische Energiequellen mit einer anderen Spannung und/oder einer anderen Leistung genutzt werden.In addition, the device 1 is connected to an electrical energy source. In Fig. 2 is shown to have a voltage of 230V and a power of 1kW. However, other electrical energy sources with a different voltage and / or power may be used.

In Fig. 1 ist gezeigt, dass ein Heizelement 5 in dem Saugkopf 1 angeordnet ist. Das Heizelement 5 kann beispielsweise ein Infrarot-Heizelement oder ein Heizwiderstand sein. Durch das Heizelement 5 wird die Eisschicht 3 erwärmt und das Eis geht in den gasförmigen Zustand über. Der so entstandene Wasserdampf steigt in Richtung 9 nach oben und wird durch einen Absaugkanal 6 in den Absaugschlauch 2 gesaugt.In Fig. 1 It is shown that a heating element 5 is arranged in the suction head 1. The heating element 5 may be, for example, an infrared heating element or a heating resistor. By the heating element 5, the ice layer 3 is heated and the ice is in the gaseous state. The resulting water vapor rises in the direction of 9 upwards and is sucked through a suction channel 6 in the suction hose 2.

In dem Saugkopf 1 sind außerdem UV-Bestrahlungsmittel 7 angeordnet. Diese bewirken eine zusätzliche Desinfizierung des Bodens 4. Die UV-Bestrahlungsmittel 7 sind am Heizelement 5 angeordnet, sodass eine durch das Heizelement 5 erwärmte Stelle relativ zügig durch die UV-Bestrahlungsmittel 7 bestrahlt wird.In the suction head 1 also UV irradiation means 7 are arranged. These cause additional disinfection of the bottom 4. The UV irradiation means 7 are arranged on the heating element 5, so that a heated by the heating element 5 point is relatively rapidly irradiated by the UV irradiation means 7.

Außerdem sind in dem Saugkopf 1 Bürstenelemente 8 angeordnet. Diese bewirken eine Reinigung des Bodens 4, bevor die Eisschicht 3 erwärmt wird und der Wasserdampf abgesaugt wird. Die Bürstenelemente verhindern beispielsweise, dass größere Verunreinigungen durch die Vorrichtung angesaugt werden und beispielsweise den Absaugschlauch 2 verstopfen.In addition, brush elements 8 are arranged in the suction head 1. These cause a cleaning of the bottom 4, before the ice layer 3 is heated and the water vapor is sucked off. The brush elements prevent, for example, that larger contaminants are sucked through the device and, for example, clog the suction hose 2.

Fig. 3 zeigt die Aufwärmung der Eisschicht 11, wenn der Saugkopf 1 in Pfeilrichtung über die Eisschicht 11 bewegt wird. Fig. 4 zeigt das Absaugen des durch das Auftauen entstandenen Wassers 12. Es ist vereinfacht dargestellt, dass das Wasser 12 entlang der dargestellten Pfeile durch den Saugkanal 6 und den Absaugschlauch 2 abgesaugt wird. Dabei kann die zu enteisende Fläche beispielsweise mit als Mittel zur Erzeugung von Wärme dienenden Heizelementen, die beispielsweise mit einer Leistung zwischen 500 W und 2,5 kW betrieben werden, auf etwa 120 °C erwärmt werden. Fig. 3 shows the heating of the ice layer 11 when the suction head 1 is moved in the direction of arrow over the ice layer 11. Fig. 4 shows the suction of the resulting water thawing 12. It is simplified, that the water 12 is sucked along the arrows shown through the suction channel 6 and the suction hose 2. In this case, the area to be deiced, for example, with as Means for generating heat-serving heating elements, which are operated for example with a power between 500 W and 2.5 kW, are heated to about 120 ° C.
