Es ist die Aufgabe der vorliegenden Erfindung, die Probleme des Standes der Technik zumindest teilweise zu Ć¼berwinden und insbesondere ein HaushaltsgerƤt mit einer optisch unauffƤlligen Mƶglichkeit zur effektiven DatenĆ¼bertragung bereitzustellen.It is the object of the present invention to at least partially overcome the problems of the prior art and in particular to provide a household appliance with an optically unobtrusive option for effective data transmission.

Diese Aufgabe wird gemƤƟ den Merkmalen der unabhƤngigen AnsprĆ¼che gelƶst. Bevorzugte AusfĆ¼hrungsformen sind insbesondere den abhƤngigen AnsprĆ¼chen entnehmbar.This object is solved according to the features of the independent claims. Preferred embodiments can be found in particular in the dependent claims.

Die Aufgabe wird gelƶst durch ein HaushaltsgerƤt, aufweisend mindestens eine Antenne in Form einer Stabantenne und einen mit der mindestens einen Antenne gekoppelten Sender und EmpfƤnger, die zur Herstellung einer Mobilfunkverbindung ausgebildet sind, wobei die mindestens eine Stabantenne in ein GriffstĆ¼ck eines lƤnglichen Griffs des HaushaltsgerƤts in Form eines TĆ¼rgriffs oder in Form eines Zusatzgriffs integriert ist, das HaushaltsgerƤt mittels des Senders, des EmpfƤngers und der Antenne zur datentechnischen Vernetzung des HaushaltsgerƤt eingerichtet ist und die Stabantenne als ein elektrisch leitender Teil einer OberflƤche des GriffstĆ¼cks ausgebildet ist.The object is achieved by a household appliance having at least one antenna in the form of a rod antenna and a transmitter and receiver coupled to the at least one antenna and designed to establish a mobile radio connection, the at least one rod antenna being fitted into a handle of an elongate handle of the household appliance Is integrated in the form of a door handle or in the form of an additional handle, the household appliance is set up by means of the transmitter, the receiver and the antenna for data networking of the household appliance and the rod antenna is designed as an electrically conductive part of a surface of the handle.

Dieses HaushaltsgerƤt weist den Vorteil auf, dass sich auf eine optisch unauffƤllige Weise eine effektive DatenĆ¼bertragung von und/oder zu dem HaushaltsgerƤt erreichen lƤsst, und zwar insbesondere auch fĆ¼r HaushaltsgerƤte mit metallischen SeitenwƤnden.This household appliance has the advantage that effective data transmission from and/or to the household appliance can be achieved in a visually unobtrusive manner, specifically also for household appliances with metallic side walls.

Ist die Stabantenne in einen TĆ¼rgriff des HaushaltsgerƤts integriert, kann das HaushaltsgerƤt ohne eine fĆ¼r einen Nutzer merkliche Ƅnderung mit einem Sender ausgestattet werden. Da der zugehƶrige Griff zudem typischerweise aus dem HaushaltsgerƤt vorragt, ist eine sehr breitwinklige Strahlungscharakteristik und damit gute Empfangbarkeit der von der Antenne ausgesandten Signale mƶglich.If the rod antenna is integrated into a door handle of the household appliance, the household appliance can be equipped with a transmitter without a change that is noticeable to the user. Since the associated handle also typically from the Household appliance protrudes, a very wide-angle radiation pattern and thus good reception of the signals emitted by the antenna is possible.

Der Zusatzgriff des HaushaltsgerƤts kann ein frontseitiger Griff zur Handhabung und Bewegung des HaushaltsgerƤts sein. Auch mag die Stabantenne in einem GriffstĆ¼ck eines Griffs eines Wasserkochers usw. integriert sein.The auxiliary handle of the household appliance can be a front handle for handling and moving the household appliance. The rod antenna may also be integrated into a handle of a kettle etc. handle.

Das HaushaltsgerƤt ist insbesondere ein elektrisches (elektrisch betriebenes) HaushaltsgerƤt, insbesondere Haushalts-GroƟgerƤt wie z.B. ein Herd, ein Ofen, ein Kochfeld, ein KĆ¼hlschrank, ein Gefrierschrank, eine Gefriertruhe, ein Sterilisator, eine Waschmaschine, eine GeschirrspĆ¼lmaschine und/oder ein WƤschetrockner. Das HaushaltsgerƤt kann auch ein HaushaltskleingerƤt sein, wie ein Wasserkocher, ein Toaster usw.The household appliance is in particular an electrical (electrically operated) household appliance, in particular a large household appliance such as a cooker, an oven, a hob, a refrigerator, a freezer, a chest freezer, a sterilizer, a washing machine, a dishwasher and/or a tumble dryer. The household appliance can also be a small household appliance, such as a kettle, a toaster, etc.

Der mit der mindestens einen Stabantenne gekoppelte Sender und EmpfƤnger kann als ein SenderempfƤnger (Transceiver) ausgebildet sein. Der Sender kann insbesondere dazu eingerichtet sein, Sensordaten eines oder mehrerer in dem HaushaltsgerƤt angeordneter Sensoren auszusenden. Der Sender, insbesondere SenderempfƤnger, kann alternativ oder zusƤtzlich zur Herstellung einer Mobilfunkverbindung ausgebildet sein, z.B. zur Fernsteuerung des HaushaltsgerƤts oder zu dessen datentechnischer Vernetzung. Der Sender kann insbesondere mit einer Steuereinrichtung des HaushaltsgerƤts gekoppelt sein.The transmitter and receiver coupled to the at least one rod antenna can be embodied as a transceiver. In particular, the transmitter can be set up to transmit sensor data from one or more sensors arranged in the household appliance. The transmitter, in particular the transceiver, can alternatively or additionally be designed to establish a mobile radio connection, e.g. for remote control of the household appliance or for its data networking. In particular, the transmitter can be coupled to a control device of the household appliance.

Die Stabantenne kann insbesondere eine Monopol- oder Dipol-Antenne sein.The rod antenna can in particular be a monopole or dipole antenna.

Es ist darĆ¼ber hinaus eine Ausgestaltung, dass das HaushaltsgerƤt metallische AuƟenwƤnde aufweist. Insbesondere fĆ¼r ein solches HaushaltsgerƤt ist die Erfindung nĆ¼tzlich, da sonst elektromagnetische Signale nur schwer auf eine optisch unauffƤllige Weise zu Ć¼bertragen sind. Solche HaushaltsgerƤte kƶnnen beispielsweise KĆ¼hlschrƤnke, WƤschebehandlungsgerƤte usw. umfassen.In addition, it is an embodiment that the household appliance has metallic outer walls. The invention is particularly useful for such a household appliance, since it is otherwise difficult to transmit electromagnetic signals in an optically inconspicuous manner. Such household appliances may include, for example, refrigerators, laundry treating appliances, and so on.

Es ist noch eine Ausgestaltung, dass das HaushaltsgerƤt einen Ofen, insbesondere Mikrowellenofen und/oder Backofen, umfasst.Another configuration is that the household appliance includes an oven, in particular a microwave oven and/or baking oven.

In den folgenden Figuren wird die Erfindung anhand von AusfĆ¼hrungsbeispielen schematisch genauer beschrieben. Dabei kƶnnen zur Ɯbersichtlichkeit gleiche oder gleichwirkende Elemente mit gleichen Bezugszeichen versehen sein.

Fig.1 zeigt in SchrƤgansicht einen Ausschnitt aus einem HaushaltsgerƤt in Form eines Backofens 1. Der Backofen 1 weist metallische AuƟenwƤnde 10 auf, z.B. aus Stahlblech. Der Backofen 1 weist ferner eine nach unten ƶffnende OfentĆ¼r 2 auf, an welcher ein TĆ¼rgriff 3 mit einem zylinderfƶrmigen GriffstĆ¼ck 4 angebracht ist. Die OfentĆ¼r 2 mag ein Sichtfenster aufweisen, braucht es aber nicht. Fig.1 shows a section of a household appliance in the form of an oven 1 in an oblique view. The oven 1 has metallic outer walls 10, for example made of sheet steel. The baking oven 1 also has a downward-opening oven door 2 on which a door handle 3 with a cylindrical handle 4 is attached. The oven door 2 may have a viewing window, but does not need it.

In den TĆ¼rgriff, genauer gesagt in das GriffstĆ¼ck 4, ist eine Stabantenne integriert. Die AuƟenwand des GriffstĆ¼cks 4 ist zumindest teilweise elektrisch leitfƤhig und stellt folglich die Antenne dar. Zuleitungen zu dem GriffstĆ¼ck 4 bzw. der darin untergebrachten Antenne kƶnnen beispielsweise durch die das GriffstĆ¼ck 4 haltenden GriffaufsƤtze 5 gefĆ¼hrt werden.A rod antenna is integrated in the door handle, more precisely in the handle 4 . The outer wall of the handle 4 is at least partially electrically conductive and consequently represents the antenna. Leads to the handle 4 or the antenna accommodated therein can be routed, for example, through the handle attachments 5 holding the handle 4 .

Der Backofen 1 weist an seiner Frontseite 6 ferner zwei Zusatzgriffe in Form von senkrecht stehenden Haltegriffen 7 auf. Die Haltegriffe 7 kƶnnen beispielsweise dazu dienen, einen Einsatz des Backofens 1 in ein Einbaumƶbel (o. Abb.) zu erleichtern. Auch in die Haltegriffe 7 kann jeweils eine Antenne integriert sein, und zwar indem die elektrisch leitfƤhigen Haltegriffe 7 direkt als Antenne ausgebildet sind. Zwar sind die Haltegriffe 7 hier senkrecht ausgebildet, jedoch kƶnnen diese auch eine andere Lage aufweisen, z.B. waagerecht ausgerichtet sein.The oven 1 also has two additional handles in the form of vertical handles 7 on its front side 6 . The handles 7 can be used, for example, to facilitate the use of the oven 1 in built-in furniture (o. Fig.). An antenna can also be integrated in each of the handles 7, specifically in that the electrically conductive handles 7 are designed directly as an antenna. Although the handles 7 are vertical here, they can also have a different position, for example, be aligned horizontally.

Haltegriffe 7 hier senkrecht ausgebildet, jedoch kƶnnen diese auch eine andere Lage aufweisen, z.B. waagerecht ausgerichtet sein.Handles 7 are designed vertically here, but they can also have a different position, e.g. be aligned horizontally.

Der Backofen 1 weist ferner eine Bedienblende 8 aus Edelstahl auf, welche mehrere Bedienelemente 9 aufweist.The baking oven 1 also has a control panel 8 made of stainless steel, which has a number of control elements 9 .

Fig.2 zeigt in Frontalansicht von vorne einen nicht erfindungsgemƤƟen Backofen 11. Der Backofen 11 weist ebenfalls eine Bedienblende 12 aus Edelstahl auf, welche mehrere Bedienelemente 9 aufweist. Jedoch ist nun in der Bedienblende 12 eine schlitzfƶrmige Aussparung 13 vorhanden, welche einem elektrisch nicht leitfƤhigen AuƟenwandbereich entspricht. Die schlitzfƶrmige Aussparung 13 ermƶglicht einen Durchgang elektromagnetischer Wellen, insbesondere von Funkwellen. Die zugehƶrige Antenne 14 kann hinter der Aussparung 13 angeordnet sein. Alternativ mag die Aussparung 13 einen Teil einer Schlitzantenne darstellen. Fig.2 shows an oven 11 not according to the invention in a front view from the front. However, there is now a slit-shaped recess 13 in the control panel 12, which corresponds to an electrically non-conductive outer wall area. The slit-shaped recess 13 allows electromagnetic waves, in particular radio waves, to pass through. The associated antenna 14 can be arranged behind the recess 13 . Alternatively, the recess 13 may represent part of a slot antenna.

Der Backofen 11 kann auch mehrere Aussparungen 13 aufweisen. Die Aussparung bzw. Aussparungen 13 kƶnnen eine geeignete Lage aufweisen, z.B. waagerecht, senkrecht usw.The baking oven 11 can also have a number of recesses 13 . The recess or recesses 13 can have a suitable position, e.g. horizontally, vertically, etc.

Fig.3 zeigt in Frontalansicht von vorne einen weiteren nicht erfindungsgemƤƟen Backofen 21. Dieser Backofen 21 weist eine Bedienblende 22 mit einem elektrisch nicht leitfƤhigen AuƟenwandbereich in Form einer lichtdurchlƤssigen Frontplatte 23 aus Kunststoff oder Glas als Blendenabdeckung auf. Durch die Frontplatte 23 ragt ein Bedienknebel 24. Durch die Frontplatte 23 sind zwei Anzeigebereiche 25 sichtbar. Hinter der Frontplatte 23 ist eine dĆ¼nne Patchantenne 26 flƤchig befestigt, fĆ¼r deren Signale die Frontplatte 23 durchlƤssig ist. Die Patchantenne 26 kann beispielsweise als eine Paneelantenne mit mehreren Patchfeldern ausgebildet sein. Fig.3 shows a front view of another oven 21 not according to the invention. This oven 21 has a control panel 22 with an electrically non-conductive outer wall area in the form of a translucent front panel 23 made of plastic or glass as a panel cover. A control knob 24 protrudes through the front panel 23. Two display areas 25 are visible through the front panel 23. A thin patch antenna 26 is fixed flat behind the front panel 23 and the front panel 23 is permeable to the signals from this antenna. The patch antenna 26 can, for example, be in the form of a panel antenna with a plurality of patch fields.

So mag die schlitzfƶrmige Aussparung von einer elektrisch nicht leitfƤhigen Abdeckung bedeckt sein, z.B. einer Blendenabdeckung. Beispielsweise mag eine Schlitzantenne in einem hinter einer nicht elektrisch leitfƤhigen Abdeckung metallischen TrƤger vorhanden sein.Thus, the slit-shaped cutout may be covered by an electrically non-conductive cover, eg a screen cover. For example, a slot antenna may be present in a metal carrier behind a non-electrically conductive cover.

Auch ist es beispielsweise mƶglich, eine Patchantenne an, insbesondere hinter, einem (elektrisch nicht leitfƤhigen) Sichtfenster in Form eines TĆ¼rfensters anzubringen, z.B. eines Mikrowellenofens, insbesondere zwischen einer Glas- oder Kunststoffscheibe und einer Mikrowellenabschirmung. Die Antenne kann auch an einem TĆ¼rfenster eines Backofens angebracht sein, z.B. an einer Zwischenscheibe oder einer ƤuƟeren Scheibe eines Scheibenpakets einer BackofentĆ¼r.It is also possible, for example, to attach a patch antenna to, in particular behind, an (electrically non-conductive) viewing window in the form of a door window, e.g. of a microwave oven, in particular between a glass or plastic pane and a microwave shield. The antenna can also be attached to a door window of an oven, e.g.

SelbstverstƤndlich ist die vorliegende Erfindung nicht auf das gezeigte AusfĆ¼hrungsbeispiel beschrƤnkt.Of course, the present invention is not limited to the embodiment shown.
