DESCRIPTION

Panel for underfloor heating

TECHNICAL SECTOR

The present invention relates to radiant floor panels.

PRIOR STATE OF THE ART

Radiant floors used in premises or homes are known. The most used underfloor heating comprises a series of ducts that are arranged inside a radiant mortar screed, under the floor panels, through which hot water is passed. The heat of the water causes the floor to radiate heat to the room where the floor is arranged. This type of underfloor heating also has the advantage that, since the ducts are arranged under the panels that form the floor, said ducts are not visible and do not affect the aesthetics of the home or premises, being able to generate the desired aesthetics using the desired panels.

However, this type of flooring requires previously installing the conduit network under the ground, which complicates its installation unless it is a premises or home under construction, and requires, in any case, high time and costs. In addition, in the event of a water leak, for example, it would be necessary to lift the floor to repair it with the implications in time, cost and complexity that this entails.

Solutions are known on the market in which radiant foils are used to avoid these problems. The radiant foil is arranged on a lower surface of a room, and said radiant foil is then covered with the panels that form a laminate floor or with the elements that form the final floor. The radiating foil comprises at least one connector through which it can be electrically powered and, when powered, it is heated and that heat is transmitted by radiation to said room.

ES1080181U discloses an underfloor heating that is based on the use of a radiant foil, but makes assembly easier compared to the solution described in the previous paragraph. The underfloor heating disclosed in this document is formed by a plurality of panels or slats, and each panel comprises an integrated electrical radiant foil and electrical terminals through which the radiant foil is electrically powered. In this way the floor can be mounted like a conventional floor, with the only difference being having to connect the terminals between the different panels and / or to an electrical power supply. Furthermore, as the radiant foil is already integrated into the panel, the heat source (the radiant foil) is closer to the space to be heated, thus greater efficiency is achieved.

EXHIBITION OF THE INVENTION

The object of the invention is to provide a panel for underfloor heating, as defined in the claims.

The panel comprises a plurality of superimposed layers, one of said layers comprising a radiant foil. By integrating the radiant foil into the panel itself, the assembly of a radiant floor made up of a plurality of panels is facilitated.

The panel comprises a first layer, a second layer that comprises the radiating foil and is arranged on the first layer, and a third layer that is a better thermal conductor than the first layer and that is arranged on the second layer, in such a way that the radiant foil is arranged between the first layer and the third layer.

The fact that the third layer is a better thermal conductor than the first layer allows more heat to be emitted from the radiant foil upwards (where the third layer is arranged) than downwards (where the first layer is arranged), thus emitting more heat. heat towards the room where the floor is arranged, increasing the thermal efficiency of said panel.

These and other advantages and characteristics of the invention will become apparent in view of the figures and detailed description of the invention.

DETAILED EXHIBITION OF THE INVENTION

In Figures 1-3 an embodiment of a panel 100 for underfloor heating 200 as shown in Figure 4 is shown by way of example. A radiant floor 200 is formed by a plurality of panels 100 according to the invention.

The panel 100 is formed by a plurality of layers 1, 2 and 3 superimposed, at least three, one of said layers 1, 2 and 3 comprising a radiant foil that heats up and emits heat when electrically powered. The fact of having such a radiant sheet allows to have a panel 100 with a low thermal inertia, since as soon as said radiant sheet is electrically fed, heat begins to be emitted towards the room where said panel 100 is arranged (where the radiant floor 200 is arranged comprising said panel 100).

Panel 100 comprises at least:

- a first layer 1,

- a second layer 2 comprising the radiating foil and which is arranged on the first layer 1, and

- a third layer 3 which is better thermally conductive than the first layer 1 and which is arranged on the second layer 2, in such a way that the radiating foil is arranged between the first layer 1 and the third layer 3 (see figure 2).

The different layers 1, 2 and 3 of the panel 100 are attached to each other by, for example, an adhesive or in the required or desired manner. Furthermore, all layers 1, 2 and 3 could be joined to each other in the same way or not.

The panel 100 further comprises a first connector T1 and a second connector T2 accessible from the outside of the panel 100, said connectors T1 and T2 being at opposite ends of the panel 100 as shown in figure 3. The connectors T1 and T2 are adapted to connect to another panel 100 or to an electrical power supply not represented in the figures. Both T1 and T2 connectors are complementary to each other, which allows the first T1 connector of one panel 100 to be coupled to a second T2 connector of another panel 100, if required. The connectors T1 and T2 are preferably arranged in the layer of the panel 100 that comprises the radiant foil (in the second layer 2), in such a way that said radiant foil can receive the necessary electrical power in a simple and direct way (more efficient).

The radiating foil comprises a foil, and the first connector T1 and the second connector T2 are preferably arranged at two opposite ends of said foil (preferably attached to said ends of said foil). The sheet comprises at least one resistor R screen-printed and electrically connected to at least one of the connectors T1 and T2, said resistor R being the one that heats up and emits heat when the radiating foil is electrically powered (when an electric current circulates through resistance R). Depending on the heat requirements to be emitted, or the heat to be emitted, a resistor R is designed with the capacity to emit more or less heat. Similarly, the radiating foil could further comprise a single screen-printed resistor R or a plurality of screen-printed resistors R.

The sheet also comprises at least one sensor, in such a way that the proposed panel 100 can fulfill additional functions to that of emitting heat. For example, the sensor can be a temperature sensor to detect and indicate the temperature on said panel 100, thus being able to be an intelligent panel 100 (which self-regulates its temperature, depending on the temperature requirements that have been established, for example). The sensor can be of another type, such as capacitive, or even the sheet can have a plurality of sensors integrated (of the same type or of different types). In the case of comprising at least one capacitive sensor C, said capacitive sensor C is preferably screen-printed on said sheet, and allows that a panel 100 in addition to emitting heat can make it possible to detect the presence or disposition of a person and / or an object on said panel 100 (at least over the area of panel 100 where the capacitive sensor C is).

Both the resistor R and the sensor are arranged between the two connectors T1 and T2 of the corresponding panel 100, especially when both are screen-printed. Said resistance R and said sensor are electrically connected to at least the first connector T1, and said first connector T1 comprises a power connection to electrically supply said resistance R and said sensor. In some embodiments the power connection is configured to supply a first power supply for the resistor R and a second power supply for the sensor. The first power supply can be 220V for example, in such a way that it offers a greater capacity to generate heat, and the second one around 5V or 3V, for example.

In any of the embodiments, a resistor can be formed by a single screen-printed resistance R or by the electrical connection of a plurality of screen-printed resistors R electrically connected in series or in parallel, the resistance in the latter case being an equivalent resistance as a result. of the connections between said plurality of resistors R.

Preferably, the radiating foil comprises at least two electrical branches connected to both connectors T1 and T2, each of said branches comprising at least one screen-printed resistor R and at least one sensor. The fact of incorporating two branches allows to obtain more heat and more sensorized zones for the same panel 100, and in a more efficient way.

Preferably, each electrical branch comprises a plurality of capacitive sensors C, which are preferably homogeneously distributed along the panel 100 (between both connectors T1 and T2). This makes it possible to obtain a panel 100 with multiple sensitive areas to detect the presence or arrangement of objects and / or people and / or objects. The distribution can be serial and aligned, for example.

The panel 100 can comprise a header module 4 that comprises the first connector T1 and, in the case that the panel 100 comprises at least one capacitive sensor C, a capacitive controller not represented in the figures and electrically connected with the first connector T1. and to the capacitive sensors C of said panel 100. The capacitive controller is electrically connected to the power connection to receive the electrical power necessary for its operation (preferably it is connected to a power supply around 3V or 5V).

The first connector T1 further comprises a communication connection for a communication bus B to which the capacitive controller is also electrically connected. Preferably, the capacitive controller comprises an I2C interface and the communication connections comprise the connections for said I2C interface, although another communication protocol could be used.

The communication connection and the power connection of the first connector T1 are also electrically connected to the second connector T2, preferably by tracks printed on the sheet, preferably said tracks being straight and parallel to each other, in such a way that if another is connected panel 100 in series to said first panel 100, the second panel 100 also receives power and is connected to the communication bus B. In the case that the panel 100 comprises two electrical branches, each of the electrical branches is on one side of these tracks.

Preferably the sheet is a plastic sheet, although it could be a sheet of fibers such as textile fibers, for example.

Preferably the first layer 1 is made of wood, although it could be made of a thermally insulating material. Preferably the third layer 3 comprises a thickness less than the first layer 1 and is made of wood, although it could be made of another material that serves as a decorative layer.
