Description

[0001] The invention relates to an infrared heater for tempering a room according to claim 1. Furthermore, the invention relates to a device for tempering a room according to the preamble of claim 22. Furthermore, the invention relates to a system for tempering at least one room according to claim 23.

[0002] It is well known that indoor spaces are often equipped with heating systems for temperature control, either conventional or liquid-filled radiators, such as convection radiators. These heating systems heat the air surrounding the radiator via the liquid or heating medium, thus increasing the room temperature. Such conventional radiators are usually connected to a heating circuit in which water is heated by burning fossil fuels.

[0003] A disadvantage of these conventional heating systems is that the combustion of fossil fuels produces CO2, and oil and gas are expected to become increasingly expensive as energy sources. Furthermore, these conventional heating systems are very slow in heating rooms.

[0004] Against this background, the object of the present invention is to provide an infrared heater and a device comprising an infrared heater as well as a system for tempering at least one room, which makes it possible to temper a room in a simple and cost-effective manner.

[0005] An infrared heater for solving this problem has the features of claim 1. This describes an infrared heater for tempering a room, comprising at least one emitting body and at least one holding element designed to couple the emitting body to a radiator, in particular a convection radiator. The holding elements allow the infrared heater, together with the emitting body, to be coupled to the existing radiator in a particularly simple and flexible manner. This allows an existing heating system in a residential building, consisting of a plurality of radiators, to be supplemented in a simple and inexpensive manner. This supplement includes the possibility of additionally tempering the room via the infrared heater. Since the infrared heater is powered by electricity, this type of heating proves to be independent of fossil fuels.Due to the environmentally friendly way of generating electricity, this type of heating proves to be ecologically sound. Furthermore, it offers the option of producing the electricity for your home yourself, which can save costs. Overall, fossil fuels such as gas and oil are expected to become more expensive than electricity. Therefore, adding infrared heating to your existing heating system can be a simple way to reduce costs.

[0006] According to the invention, it is conceivable for the radiator to be a fluid-filled radiator, preferably a convection radiator. These classic radiators, which are used for heating in many rooms, carry a heating medium through which thermal energy can be transported throughout their rooms or throughout an entire building. Using appropriate valves and pumps, thermal energy can be exchanged almost arbitrarily between different rooms via this heating medium, which is usually water. It is also conceivable for the heating medium to be fed into a heat exchanger to supply other heating elements or to heat water.

[0007] Preferably, the at least one emitting body can have at least one heating means, wherein the at least one heating means is arranged on a rear side of the emitting body. By arranging the heating means on a rear side of the emitting body, i.e., between the heating body and the infrared heater, the heating means itself can be protected from potential damage caused by impacts. Furthermore, this makes it possible to visually design the side of the infrared heater facing away from the heater. Furthermore, this arrangement avoids a potential source of danger that could arise from the heating means.

[0008] Furthermore, the invention can provide for the at least one heating means to be connected to the at least one emitting body by pressing or gluing. This connection of the heating means to the emitting body proves to be particularly simple, cost-effective, and reliable. By pressing or gluing, the claimed infrared heating device can be manufactured in a particularly cost-effective manner.

[0009] Furthermore, the invention can provide for the heating means to be operated with electricity, preferably with a mains voltage. An advantage of this solution is that electricity generated from renewable energy allows for more environmentally friendly temperature control than, for example, a gas-powered radiator. Furthermore, electricity proves to be significantly more cost-effective than fossil fuels.

[0010] Furthermore, the invention can provide for the heating means to comprise at least one resistance wire or at least one flat resistance heater. This makes the heating means particularly easy to handle and cost-effective. Essentially, only one resistance wire is required to implement the infrared heating, which is connected in a suitable manner to the back of the emitting body. This reduces manufacturing costs and thus the consumer's purchase costs.

[0011] Furthermore, according to the invention, the heating means can comprise several heating circuits, which can preferably be controlled independently of one another or jointly. By using two, three, or more heating circuits, the infrared heater can be operated in a particularly targeted manner and tailored to the respective heating situation. It is conceivable, for example, for one heating circuit to have a lower heating output than the other. Depending on the desired temperature, one of the two heating circuits or both can be operated together.

[0012] Furthermore, according to the invention, the emitting body can be made of a thermally conductive material, preferably metal, ceramic, natural stone, or another material with a thermal conductivity of more than 1.0 W / (m K). These materials have particularly advantageous thermal properties and can be designed in such a way that the emitting body becomes an interesting part of the interior design. The emitting body can have the same size as the cross-section of the radiator. If appropriate, it is also conceivable for the emitting body to be slightly larger than the radiator in order to completely cover the radiator visually and / or to ensure efficient energy exchange between the two heating systems.

[0013] Furthermore, according to the invention, the at least one retaining element can be configured to create a detachable connection between the infrared heater and the radiator. This allows the infrared heater to be flexibly attached to and removed from the radiator. Thus, no further structural measures are necessary to integrate the infrared heater according to the invention into the existing system. Likewise, the infrared heater can be removed by anyone for maintenance or cleaning purposes, without the need for special technical knowledge or tools.

[0014] Furthermore, according to the invention, the holding element can be designed as one, in particular two, preferably three or more clamps, as at least one magnet, as a screw, clamp, or locking means. These holding means allow the infrared heater to be coupled to the radiator in a particularly simple and reliable manner.

[0015] A particularly advantageous embodiment of the invention can provide for the retaining element to be an integral component of the emission body. It is conceivable that the retaining element is formed by a bent upper edge region of the emission body. This bent edge region can then be placed over the heating element in a hook-like manner. This embodiment is particularly simple to manufacture and thus cost-effective, since it can ultimately be manufactured from a single, integral workpiece.

[0016] Furthermore, according to the invention, the infrared heater can include a control unit that measures the temperature of the infrared heater and automatically adjusts the current flowing through the heating element based on the measurement results. The temperature is measured either by a thermometer directly on the infrared heater or by measuring the current flowing through the heating element. This control unit can be connected to the infrared heater's power supply via a cable or wirelessly. It is conceivable that this control unit can be accessed via a mobile device to remotely control the infrared heater.

[0017] Furthermore, according to the invention, the infrared heater can comprise a communication unit, which preferably contains a receiver and preferably a transmitter, and wherein the communication unit is preferably configured to effect temperature adjustment with other infrared heaters and / or radiators. This makes it possible to create a network of all heating systems in the area and a climate control concept. Depending on the outside temperature, the inside temperature, and a temperature selected by a person, the infrared heaters can be operated in coordination with the conventional radiators. In this way, a particularly cost-effective but equally efficient separation can be created. Particularly at low outside temperatures, it is conceivable that both heating systems are used together to achieve the necessary heating output.It is conceivable that the homogeneously emitted heat output of the infrared heater is also used to hold the heating medium, i.e. the water, of the conditional radiator in order to supply the heating circuit with thermal energy without the need for fossil fuels.

[0018] Furthermore, according to the invention, the infrared heater can be configured so that its waste heat leads to heating by convection, preferably by heating the radiator using waste heat. It is conceivable that the heating means are designed such that they thermally couple particularly efficiently with a surface of the radiator in order to transfer as much thermal energy as possible to the advertising medium of the radiator. It is conceivable that a particularly thermally conductive material is used between the heating means and the radiator.

[0019] Furthermore, according to the invention, the at least one emissive body can have at least one front panel, which preferably has a higher heat capacity than the emissive body. This increased heat capacity of a front panel allows the infrared heater to be used as a type of night storage heater. During operation of the infrared heater, this front panel is charged with thermal energy. This thermal energy is then released into the environment even after the infrared heater is switched off.

[0020] Furthermore, the invention can provide for the emitting bodies to be rollable. This particular embodiment of the invention makes it possible to flexibly connect the infrared heater to any convection heater. Thanks to its flexible shape, the infrared heater adapts particularly efficiently to the heater, resulting in particularly efficient operation of the heating system. Furthermore, the emitting body and the infrared heater can be stored in a particularly space-saving manner when not in use.

[0021] Furthermore, it is conceivable for the emission body and / or the holding element to have closable openings on a top side. These openings can be provided with a mask, which also has openings that can be brought into or out of alignment with the openings of the emission body and / or the holding element. By moving the mask relative to the emission body and / or the holding element, the openings can be brought into an open or closed position. This movement can be performed manually or automatically. The automated movement can be controlled by a control device.

[0022] A device for achieving the aforementioned object has the features of claim 22. Accordingly, it is provided that different heating modes can be selected, namely, heating by radiation, heating by convection, and a combination thereof. The ability to select situations depending on the different heating modes makes the room particularly efficient and thus saves costs.

[0023] A system for achieving the aforementioned object has features of claim 23. Accordingly, the system for controlling the temperature of at least one room comprises an infrared heater according to claim 1 and at least one liquid-filled radiator and a controller. In this system, thermal energy from the infrared heater is transferable to the radiator. The thermal energy can be stored in the radiator and / or transported to another heating element, preferably at least one further radiator, and / or a heat exchanger and / or a hot water preparation system and / or a hot water storage tank.

[0024] Preferably, it is further provided that valves and / or pumps, in particular circulation pumps, are arranged between the infrared heater, the radiator and / or the further heating element, by means of which a flow of the liquid, preferably the heating medium, can be controlled, wherein the valves and / or pumps are controlled by the control system.

[0025] In particular, the system according to the invention provides that the at least one radiator is equipped with a PCM material to better store heat. Furthermore, other heat-storing media or materials are also conceivable, which are arranged in or around the radiator. A further embodiment may provide for several radiators to be arranged one behind the other or next to each other and to be thermally coupled to one another in such a way that heat energy can be transferred directly or indirectly.

[0026] A method for achieving the aforementioned object can provide for an infrared heater according to at least one of claims 1 to 25 to be coupled to a radiator by means of the at least one holding element. According to the invention, a communication unit comprised by the infrared heater can communicate with the communication units of other infrared heaters in order to effect a temperature adjustment between the individual infrared heaters. This allows the user to easily adjust the temperature in one or more rooms without having to adjust the temperature of each infrared heater individually.

[0027] Furthermore, according to the invention, a communication unit of the infrared heater can communicate with a thermostat of the radiator. Preferably, when the infrared heater is switched on, the communication unit transmits a signal to the thermostat of the radiator. Upon receipt of the signal, the radiator is automatically switched off. This ensures that the two heating systems do not run in parallel and consume unnecessary energy.

[0028] Furthermore, according to the invention, the waste heat from the infrared heater heats the convection body, preferably the liquid contained therein, and is thus fed into the heating circuit. This reduces waste heat loss, thus increasing the energy efficiency of the entire system.

[0029] A further method for solving the problem mentioned above provides for the use of the system according to claims 23 to 25.

[0030] A preferred embodiment of the present invention will be described in more detail below with reference to the drawings in which: Fig. 1 a side view of an infrared heater of a first embodiment, Fig. 2 a side view of the infrared heater according to Fig. 1 with a radiator, Fig. 3 a rear view of the emission body according to Fig. 1, Fig. 4 a side view of a second embodiment of the infrared heater, and Fig. 5 a side view of a third embodiment of the infrared heater.

[0031] In the Fig. Figure 1 shows an embodiment of an infrared heater 10. It is designed to be attached to a radiator 12 via a holding element 11.

[0032] The infrared heater 10 comprises an emissive body 13. This is formed from a thermally conductive material, for example, metal, ceramic, natural stone, or another material with a thermal conductivity of more than 1.0 W / (m K); however, emissive bodies 13 made of other materials are also conceivable.

[0033] The material of the emission body 13 is selected so that, when the temperature increases, energy is emitted in the form of radiation almost exclusively in the infrared range of the spectrum. Ceramic materials would be particularly suitable for this purpose.

[0034] In the exemplary embodiment shown here, the holding element 11 is designed as a clamp 14, which, as in Fig. 2, is placed on the radiator 12. In this and similar embodiments, the connection between the holding element 11 and the radiator 12 is detachable and can be assembled or disassembled by the user without great effort. For secure mounting, embodiments with two or more clamps are also conceivable. It is also conceivable for the clamps 14 to be clamped onto the radiator 12 in a force-fitting manner and to rest tightly against it. Alternatively, the holding means 11 can be designed as a screw means, clamping means, or locking means.

[0035] On the back of the emission body 13, which is understood as the side which is designed to face the heating body 12, there is a heating means 15.

[0036] The heating element 15 is pressed or glued to the back of the emission body 13. However, other fastening methods are also possible.

[0037] The heating means 15 is designed as a resistance wire 16. This runs in meandering heating circuits 17. An embodiment with two heating circuits 17 is shown in Fig. 3. The two heating circuits 17 can be controlled independently of each other. Thus, the infrared heater 10 retains limited functionality even if one heating circuit 17 fails. Embodiments with only one or more than two heating circuits 17 are also conceivable. The heating circuits 17 are connected to a power supply (not shown), such as an electrical mains voltage.

[0038] When the infrared heater 10 is switched on, current flows through the resistance wire 16, causing the resistance wire 16 to heat up. This leads to a temperature increase in the infrared heater 10 and the emitting body 13, which converts the thermal energy into radiation. Alternative embodiments are also conceivable, which could lead to heating of the emitting body 13. For example, it is conceivable that the heating medium 15 is designed as a tube through which a liquid flows, which heats up when a liquid with a temperature above the temperature of the heating medium flows through the tube.

[0039] For better control of the radiated energy, the infrared heater 10 can include a control unit (not shown). This unit measures the temperature of the heating medium 15 via a temperature sensor and can vary the current heating the heating medium 15 or the temperature of the liquid heating the heating medium 15.

[0040] In the present embodiment, the emitting body 13 is designed as a plate. This form factor promotes the emission of radiation into the room and its heating. Alternatively, it is also conceivable for the emitting body 13 to be designed as several bodies connected by hinges, which form a plate when suspended from the heating body 12. Such bodies can be wound into a roll when the infrared heater 10 is not mounted, making the infrared heater 10 easier to handle and store.

[0041] A second possible embodiment of the invention is shown in Fig. 4. Here, an alternative holding element 11 is used to attach the emission body 13 to the radiator 12.

[0042] The holding element 11 here consists of magnets 18, which are attached by magnetic interaction either to the heating medium 15, the emission body 13, or the heating element 12. It is conceivable that additional magnets are mounted on one or more of these elements, which couple with the magnets 18.

[0043] In a third embodiment of the invention according to Fig. 5, a front plate 19 is mounted on the front side of the emission body 13. The front side is the side facing away from the radiator 12 and the heating medium 15. The front plate 19 could, for example, be integrally bonded to the emission body 13, but other connections are of course conceivable.

[0044] The front plate 19 could be made of a different material than the emission body 13 or have a different surface structure than the emission body 13.

[0045] In all embodiments, the infrared heater 10 can have a communication unit (not shown). This can communicate with the communication units of other infrared heaters 10 or the thermostat (not shown) of the radiator 12 or other systems, such as a smartphone via a smartphone application or building automation systems.

[0046] In all embodiments, the radiator 12 can be heated by the waste heat from the heating medium 15. This then releases the waste heat into the air, which leads to a warming of the surroundings.

[0047] Alternatively, the ambient air is heated directly by the waste heat of the infrared heater 10, so that it also heats by convection.

[0048] Alternatively, a heating medium (not shown) can flow through the radiator 12 during operation of the infrared heater 10. This medium absorbs the waste heat and feeds it into a heating circuit to which the radiator 12 is connected.
