The mattress has a mattress core enclosed by external cover layers, with integrated electrical heating wires which can be coupled to a LV source, for preheating the mattress to a required temperature. The heating wires may be incorporated in a hot melt adhesive band (3) interleaved between the spring chains of the mattress spring core and used for joining the spring chains together upon heating the hot melt adhesive.

Description

Die vorliegende Erfindung betrifft eine Matratze gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a mattress according to the preamble of the claim 1.

Derartige Matratzen sind in vielen Ausführungsformen bekannt.Such mattresses are known in many embodiments.

Dabei sind insbesondere die Matratzenkerne unterschiedlich ausgebildet. So bestehen diese beispielsweise aus Federkernen, die wiederum in Taschen gelagert sein können, wodurch sich Federstränge ergeben, die miteinander verbunden sind.The mattress cores in particular are designed differently. So exist these, for example, from spring cores, which in turn are stored in pockets can, which results in spring strands that are connected to each other.

Weiter sind Matratzenkerne bekannt, die aus Naturkautschuk oder Schaumstoff bestehen.Furthermore, mattress cores are known which consist of natural rubber or foam.

Zur Erhöhung des Schlafkomforts wird von vielen ein vorgewärmtes Bett gewünscht, wozu bislang separate Heizdecken auf die Matratze gelegt werden, um das Bett vorzuheizen. To increase sleeping comfort, many people want a preheated bed why separate electric blankets have been placed on the mattress so far Preheat bed.

Aus vielerlei Gründen bestehen jedoch Bedenken der Verwender, eine solche Heizdecke zu benutzen. Vor allem, weil üblicherweise zur Aufheizung die untransformierte Netzspannung eingesetzt wird.However, there are concerns of users for many reasons Use electric blanket. Mainly because the untransformed one is usually used for heating Mains voltage is used.

Darüber hinaus ist auch die Handhabung der bekannten Heizdecken nicht sehr anwenderfreundlich.In addition, the handling of the known electric blankets is not very user-friendly.

So wird insbesondere während einer wärmeren Jahreszeit die durch die Heizdecke gebildete Unterlagen als störend empfunden, da sie auch in ausgeschaltetem Zustand eine wärmende Wirkung entfaltet. In diesem Fall muß die Heizdecke entfernt und an einem geeigneten Ort deponiert werden.This is especially the case during a warmer season through the electric blanket documents formed perceived as annoying, since they are also in the switched off state has a warming effect. In this case, the electric blanket must be removed and deposited in a suitable place.

Darüber hinaus ist eine exakte Temperaturregelung durch die bekannten Heizdecken nicht möglich, wodurch sich ein Dauerbetrieb, insbesondere ein ständiger Betrieb während der Bettbenutzung ausschließt.In addition, there is an exact temperature control through the well-known electric blankets not possible, which results in continuous operation, especially permanent operation excludes while using bed.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Matratze der gattungsgemäßen Art so auszubilden, daß ihr Benutzungskomfort wesentlich verbessert wird.The present invention is therefore based on the object of a mattress Generic type so that their ease of use significantly improved becomes.

Diese Aufgabe wird durch eine Matratze gelöst, die die Merkmale des Anspruchs 1 aufweist.This object is achieved by a mattress having the features of claim 1 having.

Durch diese konstruktive Ausgestaltung wird praktisch die Heizdecke zum integralen Bestandteil der Matratze. Daraus ergeben sich vielerlei Vorteile.With this design, the electric blanket becomes an integral part Part of the mattress. This has many advantages.

So besteht beispielsweise die Möglichkeit, mittels einer angeschlossenen Schaltuhr sowohl den Einschaltzeitpunkt der Heizung als auch die Heizdauer festzulegen.For example, it is possible to use a connected timer to define both the switch-on time of the heating and the heating duration.

Ebenfalls kann eine exakte Temperaturregelung erfolgen, wobei ein Temperaturfühler innerhalb der Matratze den Istwert ermittelt und im Abgleich mit einer Solltemperatur, je nach Erfordernis, eine relativ exakte Regelung ermöglicht. Diese Solltemperatur kann in einem Bereich zwischen vorzugsweise 24° C und 34° C eingestellt werden, so daß die individuellen Wünsche des Benutzers berücksichtigt werden können.Exact temperature control can also be carried out using a temperature sensor the actual value is determined within the mattress and compared with a target temperature, depending on the requirements, a relatively exact regulation enables. This Desired temperature can be set in a range between preferably 24 ° C and 34 ° C be taken into account so that the individual wishes of the user can be.

Die Heizung, deren Heizdrähte durch Kupferdrähte oder andere geeignete Drähtegebildet sein können, liegt bei Einsatz in einer Federkernmatratze an den Federn an. Denkbar ist aber auch, die Heizdrähte im Bezugsstoff, zweckmäßigerweise in dem Bereich, der die Liegeseite bildet, anzuordnen. Hierdurch können auch solche Matratzen beheizt werden, deren Kern aus Naturkautschuk oder Schaumstoff besteht.The heater, the heating wires of which are formed by copper wires or other suitable wires can be applied to the springs when used in a spring mattress. It is also conceivable, the heating wires in the cover fabric, expediently in the Arrange the area that forms the lying side. This also allows such mattresses are heated, the core of which is made of natural rubber or foam.

Aus Sicherheitsgründen wird die Heizung mit gleichgerichteter Niederspannung beschrieben, wobei ein Transformator zwischengeschaltet ist, durch den die Netzspannung entsprechend transformiert wird. Nach Anliegen der Betriebsspannung an die Heizdrähte ermittelt ein Prozessor den Widerstand des Kupferdrahtes, um den Wert einem Steuergerät zu übermitteln, durch das die notwendigen Parameter steuerungstechnisch berücksichtigt werden.For safety reasons, the heater is described with rectified low voltage, a transformer being connected through which the mains voltage is transformed accordingly. After the operating voltage is applied A processor determines the resistance of the copper wire to the heating wires Value to be transmitted to a control unit by means of which the necessary parameters are used in terms of control technology be taken into account.

Bei einem Drahtbruch der Heizdrähte, einem Kurzschluß, Überhitzung oder Logikfehlern wird der Regelkreis sofort unterbrochen. Es erfolgt eine optische und akustische Warnung.In the event of a wire break in the heating wires, a short circuit, overheating or logic errors the control loop is interrupted immediately. There is an optical and acoustic Warning.

Eine interne, durch die Regelung ausgelöste Überhitzung der Matratze ist durch eine Strombegrenzung von 3 A bei dem bekannten, eingesetzten Leitungsquerschnitt nicht möglich. Eine Überhitzungsmeldung wird bei einer Temperatur > 40° C ausgegeben.An internal overheating of the mattress triggered by the regulation is caused by a Current limitation of 3 A with the known cable cross-section used not possible. An overheating message is issued at a temperature> 40 ° C.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet. Further advantageous embodiments of the invention are in the subclaims featured.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der beigefügten Zeichnungen beschrieben.An embodiment of the invention is described below with reference to the accompanying Described drawings.

Es zeigen:

Figur 1
einen Ausschnitt aus einer erfindungsgemäßen Matratze in einer Draufsicht;
Figur 2
eine schematische Seitenansicht der Matratze.
Show it:
Figure 1
a section of a mattress according to the invention in a plan view;
Figure 2
a schematic side view of the mattress.

In der Figur 1 ist als Teil einer Matratze ein Federkern 1 dargestellt, der aus mehreren, parallel zueinander verlaufenden Federsträngen 2 besteht.FIG. 1 shows a spring core 1 as part of a mattress, which consists of several there are parallel spring strands 2.

Jeder Federstrang 2 weist eine Vielzahl von hintereinander angeordneten Federn 5 auf, von denen jede in einer Tasche 8, beispielsweise aus einem Gewebe bestehend, plaziert ist. Immer zwei benachbarte Federstränge 2 sind durch ein Klebeband 3 miteinander verklebt, das einen thermischen Kleber aufweist, der durch Erhitzung klebfähig wird.Each spring strand 2 has a plurality of springs 5 arranged one behind the other on, each of which consists of a pocket 8, for example made of a fabric, is placed. Always two adjacent spring strands 2 are by an adhesive tape 3rd glued together, which has a thermal adhesive, which by heating becomes sticky.

Diese Erwärmung erfolgt durch im Klebeband 3 verlaufende Heizdrähte, die an ein nicht dargestelltes Steuergerät angeschlossen sind, mit dem eine Temperaturregelung unterhalb der Schmelztemperatur des thermischen Klebers erfolgt. Durch diese Heizdrähte 6 kann eine Temperierung einer Matratze erreicht werden, deren Bestandteil der Federkern 1 ist.This heating takes place by means of heating wires running in the adhesive tape 3, which are connected to a Control unit, not shown, are connected, with which a temperature control takes place below the melting temperature of the thermal adhesive. Through this Heating wires 6 can be brought to a temperature of a mattress, the component of which the spring core is 1.

Das Steuergerät selbst ist als Stecker-Netzgerät ausgebildet und mit einer Leiterplatte versehen, auf der sich die Logik sowie die Spannungsversorgung und der Lastkreis befindet. Die Temperatureinstellung wird dabei analog über ein skaliertes Potentiometer vorgenommen. The control unit itself is designed as a plug-in power supply and with a printed circuit board provided on which the logic as well as the voltage supply and the Load circuit is located. The temperature setting is analog via a scaled Potentiometer made.

Denkbar ist aber auch, eine digitale Einstellung der Temperatur sowie diverse Ein- und Ausschaltzeiten über ein Tableau mit LCD-Display vorzusehen.However, it is also conceivable to digitally set the temperature and various inputs and Switch-off times must be provided on a panel with an LCD display.

Die Verbindung zum Heizkabel sowie einem Temperaturfühler, der innerhalb der Matratze angeordnet ist, erfolgt über einen Stecker.The connection to the heating cable and a temperature sensor, which is inside the Mattress is arranged via a plug.

Das Heizkabel selbst kann aus einem extrudierten Flachprofil, in das Kupferdrähte eingebracht sind, bestehen.The heating cable itself can be made from an extruded flat profile into which copper wires are introduced.

Weiter ist in dem Steuergerät ein Prozessor angeordnet, der den ermittelten analogen Temperatur-Istwert mit einem eingestellten Sollwert vergleicht. Eine programmierte Fuzzy-Logik berechnet aus den zur Verfügung gestellten Parametern die äußeren Temperatureinflüsse, so daß eine energiesparende 2-Punktregelung mit minimaler Hysterese entsteht.Furthermore, a processor is arranged in the control device, which is the determined analog Comparing the actual temperature value with a setpoint. A programmed one Fuzzy logic calculates the external ones from the parameters provided Temperature influences, so that an energy-saving 2-point control with minimal Hysteresis arises.

Während der Sollwert über ein Potentiometer eingestellt wird, wird der Istwert über einen geeigneten Fühler aufgenommen.While the setpoint is set using a potentiometer, the actual value is set via a suitable sensor was added.

Wie insbesondere die Figur 2 sehr deutlich zeigt, ist die Ober- und Unterseite des Federkerns 1 jeweils mit einem Deckvlies 4 abgedeckt, in dem gleichfalls Heizdrähte 6 angeordnet sein können.As shown particularly clearly in Figure 2, the top and bottom of the Spring core 1 each covered with a cover fleece 4, in the same way Heating wires 6 can be arranged.
