Description

Die Erfindung betrifft ein Haushaltsgerät, insbesondere ein Bodenreinigungsgerät; nach dem Oberbegriff von Patentanspruch 1.The invention relates to a household appliance, in particular a floor cleaning device; according to the preamble of claim 1.

Viele Haushaltsgeräte weisen einen Elektromotor auf, welcher zumindest in Teilbereichen von einem oder mehreren Abdeckelementen umgeben ist. Die Abdeckelemente dienen dabei der Erreichung von elektrischer Sicherheit und/oder zur Geräuschdämmung und/ oder zur Wärmedämmung. Bei Bodenreinigungsgeräten übernehmen derartige Abdeckungselemente auch häufig die Funktion eines Führungselements, welches einen Luftstrom, insbesondere einen auszublasenden Luftstrom, in eine gewünschte Richtung lenkt.Many household appliances have an electric motor, which is surrounded at least in some areas by one or more cover elements. The cover serve to achieve electrical safety and / or noise reduction and / or thermal insulation. In floor cleaning devices, such cover elements also often assume the function of a guide element which directs an air flow, in particular a stream of air to be discharged, in a desired direction.

Der Erfindung liegt die Aufgabe zugrunde, ein Haushaltsgerät mit einem Elektromotor und einem Adeckelement für den Elektromotor anzugeben, bei dem das Abdeckelement einfach und kostengünstig herstellbar ist und verbesserte Geräusch- und Wärmedämmungseigenschaften aufweist.The invention has for its object to provide a household appliance with an electric motor and a Adeckelement for the electric motor, in which the cover is simple and inexpensive to produce and has improved noise and thermal insulation properties.

Diese Aufgabe wird erfindungsgemäß durch ein Haushaltsgerät mit den Merkmalen gemäß Patentanspruch 1 gelöst.This object is achieved by a household appliance with the features according to claim 1.

Demgemäß umfasst ein Haushaltsgerät, insbesondere ein Bodenreinigungsgerät, einen Elektromotor und mindestens ein Abdeckelement für den Elektromotor, wobei das mindestens eine Abdeckelement zumindest in Teilbereichen aus einem Verbundmaterial besteht, welches zumindest einen Kunststoff und Leder enthält.Accordingly, a household appliance, in particular a floor cleaning appliance, comprises an electric motor and at least one covering element for the electric motor, the at least one covering element consisting at least in partial areas of a composite material which contains at least one plastic and leather.

Leder ist bekanntlich eine durch Gerbung chemisch haltbar gemachte Tierhaut, deren natürliche Faserstruktur weitgehend erhalten ist. Es ist ein geschmeidiges, zähes, relativ festes, haltbares und vielseitig einsetzbares Material. Leder ist relativ undurchlässig für Wasser, trotzdem ist es atmungsaktiv, d. h. ausreichend durchlässig für Luft und Wasserdampf.Leather is known to be chemically preserved by tanning animal skin whose natural fiber structure is largely preserved. It is a supple, tough, relatively strong, durable and versatile material. Leather is relatively impermeable to water, yet it is breathable, ie sufficiently permeable to air and water vapor.

Ein derartiges, zumindest einen Kunststoff und Leder umfassendes, Verbundmaterial zeichnet sich durch eine im Vergleich zu herkömmlichen, allein aus Kunststoffen gefertigten Abdeckelementen, erhöhte Wärme- und Schalldämmung aus, ist aber dennoch einfach und kostengünstig, z.B. im Rahmen eines Spritzgussverfahrens, verarbeitbar. Als Kunststoff kann dabei z.B. ein Kunststoff auf Polyethylen-Basis oder Polypropylen-Basis Verwendung finden. Durch Verwendung eines entsprechenden Kunststoffes kann der Härtegrad des Verbundmaterials in einem weiten Bereich variiert werden.Such a composite material comprising at least one plastic and leather is distinguished by an increased heat and sound insulation compared to conventional covering elements made entirely of plastics, but is nevertheless simple and inexpensive, e.g. as part of an injection molding process, processable. As a plastic, e.g. use a polyethylene-based or polypropylene-based plastic. By using a corresponding plastic, the degree of hardness of the composite material can be varied within a wide range.

Das Abdeckelement kann vielfältige Aufgaben übernehmen. So kann es beispielsweise unmittelbar zur Geräuschdämmung und/oder zur Wärmedämmung dienen. In diesem Fall wird durch den Einsatz des Verbundmaterials ein verbesserter Dämmungseffekt erreicht. Dieser kann entweder dazu genutzt werden, das außerhalb der Abdeckung wahrnehmbare Geräusch und/oder die nach außen abgestrahlte Wärme weiter abzusenken oder auch um die gewünschte Wärme- und Geräuschdämmung mit geringerer Materialstärke des Abdeckelements und damit einhergehender Materialersparnis zu erreichen.The cover can take on a variety of tasks. For example, it can be used directly for noise reduction and / or thermal insulation. In this case, an improved insulation effect is achieved through the use of the composite material. This can either be used to further reduce the noise perceivable outside the cover and / or the radiated heat to the outside or to achieve the desired heat and noise insulation with lower material thickness of the cover and associated material savings.

Neben der Geräusch- und Wärmedämmung kann ein Abdeckelement aber zumindest primär auch anderen Zwecken, wie z.B. einer Erzielung von elektrischer Sicherheit oder im Falle eines Bodenreinigungsgerätes auch der Führung eines Luftstromes, insbesondere eines auszublasenden Luftstromes, dienen. In diesem Fall kann aufgrund der verbesserten Wärme- und Schalldämpfungseigenschaften des Verbundmaterials ggf. auf zusätzliche Maßnahmen zur Wärme- und Geräuschdämmung verzichtet werden.However, in addition to noise and heat insulation, a cover member may at least primarily serve other purposes, such as e.g. Achieving electrical safety or, in the case of a floor cleaning appliance, also guiding an air flow, in particular a stream of air to be discharged, serve. In this case, it may be possible to dispense with additional measures for heat and noise insulation due to the improved heat and sound damping properties of the composite material.

Gemäß einer Ausführungsform der Erfindung weist das Verbundmaterial Lederfasern auf, welche in den zumindest einen Kunststoff eingebettet sind. In diesem Fall wirkt der Kunststoff als stützende Matrix für die Kunststofffasern, so dass das Abdeckelement auch mechanischen Belastungen gut standhalten kann.According to one embodiment of the invention, the composite material on leather fibers, which are embedded in the at least one plastic. In this case, the plastic acts as a supporting matrix for the plastic fibers, so that the cover can withstand mechanical stresses well.

Eine Ausführungsform der Erfindung sieht vor, dass der Volumenanteil des Leders an dem Verbundmaterial 10 bis 70 % beträgt. Der untere Grenzwert wird dabei von der gewünschten zusätzlichen Dämmwirkung und der obere Grenzwert durch die erforderliche mechanische Belastbarkeit bestimmt.An embodiment of the invention provides that the volume fraction of the leather on the composite material is 10 to 70%. The lower limit is determined by the desired additional insulation effect and the upper limit by the required mechanical strength.

Um besonderen Umgebungsbedingungen, z.B. hinsichtlich mechanischer Belastbarkeit oder elektrischer Sicherheit, Rechnung zu tragen, kann es vorgesehen, sein dass das Abdeckelement ein Kernelement und mindestens ein das Kernelement zumindest in Teilbereichen umgebendes Mantelelement umfasst, wobei zumindest das Kernelement und/oder mindestens eines der Mantelelemente aus dem Verbundwerkstoff besteht.For special environmental conditions, e.g. With regard to mechanical load-bearing capacity or electrical safety, it can be provided that the cover element comprises a core element and at least one sheath element surrounding the core element at least in partial regions, wherein at least the core element and / or at least one of the sheath elements consists of the composite material.

Um auch in diesem Fall eine leichte Verarbeitbarkeit und damit aufwandsarme Herstellung, z.B. durch Spritzguss, zu gewährleisten, ist es vorteilhaft, wenn ein nicht aus dem Verbundwerkstoff bestehendes Mantelelement oder Kernelement auch aus einem Kunststoff oder einem weiteren, von dem Verbundmaterial verschiedenen, Kunststoff-Verbundmaterial besteht. Das weitere Kunststoff-Verbundmaterial kann dabei auch ein weiteres Leder-Verbundmaterial sein, welches sich von dem Verbundmaterial durch einen unterschiedlichen Volumenanteil des Leders und/oder eine andere Kunststoffkomponente unterscheidet. Grundsätzlich können das Kernelement und das Mantelelement unterschiedliche Kunststoffkomponenten enthalten, so dass das Abdeckelement optimal an die jeweiligen konkreten Anforderungen angepasst werden kann.In this case as well an easy processability and thus low-effort production, e.g. by injection molding, it is advantageous if a non-existing composite material jacket element or core element also consists of a plastic or another, different from the composite material, plastic composite material. The further plastic composite material may also be a further leather composite material, which differs from the composite material by a different volume fraction of the leather and / or another plastic component. In principle, the core element and the jacket element may contain different plastic components, so that the cover element can be optimally adapted to the respective specific requirements.

Weitere Merkmale und Vorteile der Erfindung werden nachfolgend anhand eines Ausführungsbeispieles mit Bezugnahme auf die beigefügte Figur erläutert, welche eine Schnittdarstellung eines erfindungsgemäßen Haushaltsgeräts in Form eines Staubsaugers zeigt.Further features and advantages of the invention will be explained below with reference to an embodiment with reference to the accompanying figure, which shows a sectional view of a household appliance according to the invention in the form of a vacuum cleaner.

In Figur 1 ist in Schnittdarstellung ein Staubsauger 1 dargestellt welcher ein Gehäuse 2 aufweist. Im Gehäuse 2 befindet sich ein Staubraum 3, in welchem ein Wechselfilterbeutel angeordnet werden kann. Darüber hinaus ist in dem Gehäuse 2 ein Elektromotor in Form eines Gebläsemotors 4 angeordnet. Eine vom Gebläsemotor 4 angesaugte Luft gelangt beim Saugen über eine nicht dargestellte Bodendüse und einen nicht dargestellten Saugschlauch in den Wechselfilterbeutel , der die Staub- und/oder Schmutzpartikel herausfiltert, passiert dann den Gebläsemotor 4, ein Ausblasfilter 5 und gelangt letztendlich über Auslassöffnungen in Form eines Ausblasgitters 6 wieder aus dem Gehäuse 2 des Staubsaugers 1 nach außen.In FIG. 1 is a sectional view of a vacuum cleaner 1 is shown which has a housing 2. In the housing 2 is a dust chamber 3, in which a replaceable filter bag can be arranged. In addition, an electric motor in the form of a blower motor 4 is arranged in the housing 2. A suctioned by the fan motor 4 air passes while sucking on a floor nozzle, not shown, and a filter bag, not shown, which filters out the dust and / or dirt particles, then passes the fan motor 4, an exhaust filter 5 and finally passes through outlet openings in the form of a Outlet grille 6 again from the housing 2 of the vacuum cleaner 1 to the outside.

Der Gebläsemotor 4 ist in einem Teilbereich von einem Abdeckelement 7 umgeben, welches häufig auch als Kapsel bezeichnet wird. Dieses Abdeckelement 7 dient zum einen der Führung des auszublasenden Luftstromes, welcher in Figur 1 in Form von Pfeilen 8 dargestellt ist. Zum anderen dient das Abdeckelement 7 aber auch zur Wärme- und Geräuschdämmung. Darüber hinaus wird durch das Abdeckelement, welches in dem dargestellten Ausführungsbeispiel zusammen mit Teilen des Gehäuses 2 des Staubsaugers eine Art Motorgehäuse für den Gebläsemotor 4 bildet, auch die elektrische Sicherheit des Staubsaugers 1 gewährleistet. Da der allgemeine Aufbau eines Staubsaugers allgemein bekannt ist, wird darauf ansonsten nicht weiter eingegangen.The fan motor 4 is surrounded in a partial area by a cover element 7, which is often referred to as a capsule. This cover member 7 serves to guide the air stream to be bled, which in FIG. 1 in the form of arrows 8 is shown. On the other hand, the cover 7 but also for heat and noise insulation. In addition, the electrical safety of the vacuum cleaner 1 is ensured by the cover, which forms a kind of motor housing for the fan motor 4 in the illustrated embodiment, together with parts of the housing 2 of the vacuum cleaner. Since the general structure of a vacuum cleaner is well known, it will not be discussed otherwise.

Um eine möglichst gute Geräusch- und Wärmedämmung zu erreichen, ist das Abdeckelement 7 z.B. durch ein Spritzgussverfahren aus einem Verbundmaterial gefertigt, welches zumindest einen Kunststoff und Leder enthält. Das Leder kann dabei z.B. in Form von Lederfasern in den Kunststoff eingebettet sein. Die Lederfasern können beispielsweise aus Lederabfällen gewonnnen werden. Als Kunststoff eignen sich z.B. Kunststoffe auf Polyethylen- oder Polypropylen-Basis. Der Volumenanteil des Leders liegt vorzugsweise in einem Bereich von 10 - 70 %.In order to achieve the best possible noise and heat insulation, the cover member 7 is e.g. made by injection molding of a composite material containing at least one plastic and leather. The leather may e.g. be embedded in the plastic in the form of leather fibers. The leather fibers can be obtained, for example, from leather waste. As plastic, e.g. Polyethylene or polypropylene based plastics. The volume fraction of the leather is preferably in a range of 10 - 70%.

Um speziellen Anforderungen des Staubsaugers 1 oder allgemein eines Haushaltsgerätes gerecht zu werden, kann das Abdeckelement 7 auch ein Kernelement und mindestens ein dieses Kernelement zumindest teilweise umgebendes Mantelelement aufweisen. Es ist dann möglich, nur eines der Elemente aus dem Leder-Verbundmaterial zu fertigen und das jeweils andere Element aus einem anderen Material, wie z.B. einem reinen Kunststoff oder einem anderen Kunststoff-Verbundmaterial, insbesondere auch einem anderen Leder-Verbundmaterial, herzustellen. Je nach den konkreten Anforderungen kann dabei auch ein im Vergleich zum Kunststoff des Leder-Verbundmaterials unterschiedlicher Kunststoff verwendet werden.In order to meet specific requirements of the vacuum cleaner 1 or generally a household appliance, the cover 7 may also have a core element and at least one of these core element at least partially surrounding the jacket element. It is then possible to manufacture only one of the elements of the leather composite material and the other element of a different material, such as. a pure plastic or other plastic composite material, in particular also another leather composite material to produce. Depending on the specific requirements can also be used in comparison to the plastic of the leather composite material different plastic.

Die Ausführung des jeweils anderen Elements auf Kunststoffbasis bietet den Vorteil, dass dann das gesamte Abdeckelement 7 trotzdem in einem Arbeitsgang z.B. mit Hilfe eines Spritzgussverfahrens, gefertigt werden kann.The execution of each other plastic-based element has the advantage that then the entire cover 7 can still be made in one operation, for example by means of an injection molding process.

Die dargestellte Ausführungsform des Staubsaugers weist nur ein Abdeckelement 7 auf. Selbstverständlich können aber auch mehrere Abdeckelemente vorgesehen sein, welche dann alle oder teilweise aus dem Leder-Verbundmaterial bestehen.The illustrated embodiment of the vacuum cleaner has only one cover 7. Of course, however, several cover elements may be provided, which then all or partially made of the leather composite material.

Die Erfindung wurde anhand eines Staubsaugers erläutert ist aber selbstverständlich auch auf alle anderen Haushaltsgeräte mit einem Elektromotor anwendbar, bei welchen Geräusch- und/oder Wärmedämmung eine Relevanz besitzen.The invention has been explained with reference to a vacuum cleaner but of course also applicable to all other household appliances with an electric motor, in which noise and / or thermal insulation have relevance.
