Description

The invention relates to a functional body according to the preamble of claim 1 and a functional body for a covering according to claim 19. Furthermore, the invention relates to a covering according to claim 21.

It is known to install a heating line under the individual covering elements for temperature control, in particular for heating, a covering, preferably a floor covering or a wall covering or a ceiling element. In this way, for example, public spaces, sidewalks, but also terrace areas of gastronomic or event areas or private terraces can be heated. In this way, the areas mentioned can be kept free of ice even in winter. Electric cables or pipes that carry a heatable heat medium are normally used to heat the coverings. These lines are arranged under the entire area of the floor covering in such a way that the surface is heated homogeneously. For this purpose, the lines are usually laid on split or lean concrete or the like, on which the covering is also laid. In these known methods, the heating cable is first integrated into a layer forming the foundation and then the covering is laid on this line or on this layer. The mentioned coverings can be tiles, tiles or panels or other means for covering a floor or for cladding a wall or ceiling. A disadvantage of the known systems for heating floor coverings is that only the temperature of the entire surface exposed to the covering can be controlled. This control consists in turning the heating power on or off. Individual, location-dependent, dosed heating cannot be achieved in this way. Rather, the electrical energy made available is transferred to the floor covering as thermal energy. This can sometimes lead to excessive heating of the floor covering. In addition to the health risks for those who are on the surface, there is also an increased risk of fire. In addition, this heating of the entire floor covering is very energy-intensive and therefore cost-intensive.

The object of the present invention is to create a functional body and a covering that can be temperature-controlled in a particularly energy-efficient manner.

A functional body for solving this problem has the features of claim 1. Accordingly, provision is made to create a functional body, in particular for a floor covering or a wall covering or for a ceiling element, such as a tile, a tile or a panel, with an underside that can be placed on the substrate and a temperature-controlled upper side. A heating wire for temperature control of the upper side or a covering can be integrated on or in the top side of the functional body. According to the invention it is provided that at least one means for switching or regulating a temperature of the upper side or of the covering is arranged in the functional body. Because each functional body has at least its own means for switching or regulating the temperature of the covering, the temperature of each functional body can be regulated individually and as required. In particular, when the functional body is initially heated, a great deal of electrical energy is required, whereas the heated upper side has to be subjected to a lower electrical power at a setpoint temperature in order to keep the temperature constant. If the temperature of the top is above the target temperature, the supply of electrical power is interrupted. If the measured temperature falls below the target temperature, the heating wire is again supplied with electrical energy. For some areas, for example a terrace, an increased temperature on the top side is desirable, while other areas can also have a lower temperature. Such an individual control of each functional body can be implemented by the individual means for switching or regulating the temperature, which are assigned to each functional body according to the invention. As a result of this individualized control, the top is only supplied with exactly as much electrical energy as is necessary. This saves electrical energy and thus costs. A covering-forming material such as mortar or concrete can be poured directly onto the top of each functional body. Alternatively, a covering can also be attached directly to the top of the functional body.

It is preferably provided that the means for switching or regulating is designed in several parts, with a socket of the means being firmly integrated into the functional body and a plug being able to be plugged into the socket from the underside. As a result, the socket becomes an integral part of the functional body and is in direct contact with the top or the covering. As a result, a temperature sensor arranged in the means for switching or regulating can directly measure the temperature of the upper side in a very precise manner.

It is also conceivable that the means for switching or regulating is designed in several parts, a socket of the means being releasably connectable to a holding element which is integrated in the functional body and a plug can be plugged into the socket from the bottom. The holding element can already be used during the production of the functional body are placed in the material, in particular foam or the like, and during the further processing of the functional body becomes an integral part of the body, in which the means for temperature control can be flexibly used and removed.

It is also provided that a thermally conductive element, in particular a metal sleeve, or an at least semitransparent opening, in particular a membrane, is arranged in the socket, which directly adjoins the top or an underside of the covering, preferably is in contact with the covering . This membrane is transparent to thermal radiation or infrared radiation so that the temperature sensor can measure the temperature of the covering directly.

It is preferably further provided that two interrupted ends or poles of the heating wire are fastened in the socket and can be electrically connected to one another by the plug. Without the plug inserted in the socket, the heating wire is interrupted so that no current can flow. As soon as the plug is plugged into the socket, the electrical circuit closes and the heating wire can give off thermal energy to the top or the covering. Because a temperature sensor is arranged in the plug, which is positioned above or in the opening, in particular above the membrane when the plug and socket are plugged together, the plug can either close the circuit by means of an integrated switch depending on the determined temperature or open. For example, if the measured temperature of the top or the covering is above the previously determined target temperature, the switch in the plug interrupts the flow of current through the heating wire so that no further heat energy is deposited by the heating wire in the top or in the covering. If the measured temperature is below the target temperature, the heating output can be increased if necessary. Since each of the adjacent functional bodies or coverings has its own temperature sensor with the corresponding plug of the socket, each functional body or each heating wire circuit can be controlled accordingly. The target temperature can either be set wirelessly via radio, W-LAN, Bluetooth0 or the like on the means for switching or regulating the temperature or manually on the plug before the functional body is laid.

The individual heating wire circuits of each functional body can either be coupled to one another and connected to one another in parallel or in series, or they can each have their own supply line. The heating wires can be supplied with electrical energy from a common energy source which is positioned either under the entirety of the functional bodies or next to them.

According to the invention, the means for switching or regulating the temperature can be a fixed temperature controller, a bimetal switch, a fuse or the like. In the case of a bimetallic switch, the temperature sensor or temperature sensor can be designed as a curved bimetallic snap switch. This can be in direct contact with the membrane or with the covering and can therefore react quickly to temperature changes in the upper side or in the covering. When the specified target temperature is reached, a bimetal snap disk causes the electrical circuit to open momentarily. After the cooling phase, it snaps back into its original position, which closes the heating wire circuit again. In addition, further means for switching or regulating the heating temperature are also conceivable.

In addition, it can be provided according to the invention that each functional body has one, two or more means for switching or regulating the temperature. In particular, it is conceivable that each heating wire in a functional body has at least one means for switching or regulating the temperature. It can thus be provided that the covering has two means for switching or regulating the temperature per square meter. Depending on the requirements or application, both the number and the positioning of the individual means can be adjusted.

In particular, it is provided that the functional body consists of a heat-insulating material, such as foam, styrofoam, plastic, wood fibers, rock, glass or mineral wool, vacuum insulation panels or the like, and is preferably coated with mortar or concrete as a covering. By choosing such a heat-insulating material, the thermal energy of the heating wire is almost completely transferred to the top or the covering. Because of the poor thermal conductivity of the substances mentioned, only a small amount of thermal energy is absorbed by the functional body itself. In addition, the materials mentioned can be processed very well and easily or their shape can be changed.

Another embodiment can provide that the top of the functional body has at least one, in particular helical or meander-shaped, channel or a honeycomb-like pattern or a profile with a waffle structure for receiving the heating wire for temperature control, the channel or the pattern over the entire Top extends. These channels or these structures can be with an adhesive or with Mortar or concrete are poured, which serve both as a covering, as well as a connecting means for a covering.

It can further be provided according to the invention that two first ends or connections of the heating wire are led away over an edge of the functional body and have means, in particular plugs, terminals, crimp connections, soldered connections or the like, for connecting to a further cable, preferably further heating wires adjacent functional body. These connections allow several functional bodies to be connected to one another in a simple manner and to create an individual terrace shape.

Preferably, it is also provided that the underside of the functional body has at least one, in particular helical or meander-shaped, channel or a honeycomb-like pattern for receiving the heating wire, the underside of the functional body having a symmetrical channel structure for receiving cable sections of equal length, so that plug connections of adjacent functional bodies in the protrude the same dimensions over the respective functional body.

Finally, it can be provided that side areas of the functional body have recesses for receiving the means, in particular plugs, terminals, crimp connections, soldered connections or the like, for connecting several heating wires of adjacent functional bodies.

A functional body for a covering to achieve the object mentioned at the beginning has the features of claim 19. Accordingly, it is provided that the functional body for a covering, in particular a floor covering or a wall covering or for a ceiling element, such as a tile, a tile or a panel, has an underside that can be placed on a substrate and an upper side that can be joined to the covering, with According to at least one of claims 1 to 18, a heating wire for temperature control of the covering can be arranged on or in the upper side. At least one means for switching or regulating a temperature of the covering is preferably arranged in the functional body.

A covering to achieve the object mentioned at the beginning has the features of claim 21. Accordingly, it is provided that a covering, in particular a floor covering or a wall covering or a ceiling element, such as a tile, a tile or a panel, a fiber cement board, a plasterboard or a decoupling membrane, which has one side with a functional body according to at least one of the Claims 1 to 18 can be put together.

• 2 eine Sicht auf eine Unterseite des Funktionskörpers,
• 3 eine Ausschnittsvergrößerung der 2, und
• 4 eine schematisierte Darstellung eines Steckers.

A preferred embodiment of the present invention is described in more detail below with reference to the drawing. In this show:

• 1 a side view of a functional body with a covering,
• 2 a view of an underside of the functional body,
• 3 an enlargement of the 2 , and
• 4th a schematic representation of a connector.

In the 1 is a highly schematic side view of a functional body 10 shown on its top 11 a covering 12 is arranged. With the covering 12 it can be, for example, a floor covering or a wall covering or a ceiling element, such as a tile, a tile or a panel.

Equally, however, it is also conceivable that on the top 11 a layer of mortar, concrete or the like as a floor covering 12 is arranged. The layer of mortar, concrete or the like can be an integral part of the functional body 10 be.

By placing several functional bodies next to one another 10 with one topping each 12 almost any surface can be created. The essence of the invention is that the functional body has heating wires that are inserted into the surface of the functional body 10 are integrated or on the surface 11 are positioned. By having these heating wires in direct contact with the pavement 12 can be transferred to the surface through the heating wires by applying electrical energy accordingly. This effectively allows the topping 12 heat.

Functional bodies lying next to one another 10 can be coupled to one another in such a way that the various heating wire circuits are connected together either in parallel or in series. For this purpose, the corresponding ends of the heating wires can have detachable connectors, such as, for example, plugs. It is conceivable that every functional body 10 has its own energy source or the entirety of all joined functional bodies 10 is supplied with electrical energy by a common energy source.

According to the functional body 10 medium 13 assigned to switching or regulating a temperature of the covering. This means 13 are in the functional body 10 integrated in such a way that they are at the top 11 connect and at least partially in direct contact with the covering 12 stand. This means 13 form a switch for the heating wires. The means 13 be designed as a fixed temperature controller, bimetal switch, fuse or the like. Alternatively, it is also provided that in the functional body 10 a holding element for the agent 13 is integrated. Whereby the means in the holding element 13 can be inserted and removed again. This is done depending on requirements or for maintenance purposes.

The middle 13 for switching or regulating the temperature of the surface 12 is composed of two components in the embodiment shown here. In the functional body 10 A socket is permanently integrated 14th ( 2 , 3 ). This jack 14th is in such a way in an opening in the functional body 10 arranged that they are with a membrane 15th with the top 11 of the functional body 10 closes and thus in direct contact with the surface 12 stands. Also run in the socket 14th two cable ends 16 a heating wire circuit (not shown) together. These cable ends 16 are open.

On the socket 14th is a plug 17th pluggable. This plug 17th forms the second component of the remedy 13 . By plugging together the two cable ends 16 through the connector 17th connected to each other so that the electrical circuit is closed again and electricity can flow. However, the circuit is only closed when the covering 12 does not exceed a certain target temperature. The temperature of the topping 12 is by a temperature sensor 18th on the plug 17th through the membrane 15th measured. With this in the 4th temperature sensor shown schematically 18th it can, for example, be a bimetal temperature sensor.

The target temperature to which the topping 12 to be heated can be done manually directly on the connector 17th can be set. For this, it is necessary that before laying the functional body 10 or the covering 12 the temperature is set and then the plug 17th into the socket 14th is plugged. Alternatively, it is also conceivable that the plug 17th can be controlled wirelessly and the setpoint temperature is set individually by, for example, a mobile radio device.

Every functional body 10 several heating wire circuits, not shown, can be assigned, each with a corresponding means 13 exhibit. By joining several functional bodies lying next to one another 10 with the toppings 12 can have different temperature gradients over several functional bodies 10 be generated. By setting the means individually 13 to switch or regulate the temperature, for example, areas of a terrace can be controlled to be warmer than others. It is also conceivable that functional bodies 10 that are used for a floor covering are supplied by the same energy source as the functional body 10 that are used for a heated wall covering. Through the individual temperature setting on the plugs 17th different temperatures can be achieved on the walls and on the floor.

This demand-dependent setting of the temperature can on the one hand create a particularly high level of well-being and on the other hand save electrical energy and thus costs. Through the temperature sensor 18th or the plug 17th , which works here as a regulator or switch, is only used as much energy as is necessary.

The heating wires can be between the functional body 10 and the topping 12 into the surface of the functional body in a variety of ways 10 be integrated. For this purpose, it is conceivable, for example, that the heating wires are cast in or in an, in particular meander-like, prefabricated channel in the functional body 10 be relocated. By gluing the covering 12 with the functional body 10 and the integrated resources 13 A compact module is created for switching or regulating the temperature, from which larger, temperature-controlled terrace areas can be combined with other modules.
