Description

[0001] The invention relates to an infrared emitter arrangement for an infrared irradiation device and in particular for a low-temperature infrared cabin.

[0002] Infrared radiator systems are used in infrared irradiation devices for heat applications aimed at locally warming a specific area of ​​the body (e.g., neck, back, joints, sinuses, etc.). Another important application is whole-body or systemic heating, in which the core body temperature is specifically raised. This heating process occurs through the absorption of infrared radiation by the skin and the transport of warmed blood to the body's core. Heat applications, for example, using infrared saunas, serve to improve well-being and alleviate numerous, especially chronic, musculoskeletal complaints. Heat applications stimulate blood circulation, tissue nourishment, and metabolism, as well as providing pain relief and muscle relaxation.For heat applications using infrared radiation, so-called infrared-C rays are particularly suitable, as these penetrate only a small depth into the skin and thus avoid unwanted stimuli on metabolically active skin cells.

[0003] Suitable radiation elements for generating infrared radiation for the aforementioned applications include heating conductor arrangements based on electrically conductive carbon fibers. The carbon fiber conductors are electrically energized, behave like an electrical resistor, and consequently heat up, leading to a very efficient emission of radiation in the infrared wavelength range.

[0004] German patent DE 20 2006 007 228 U1 describes an infrared surface heating element that, based on an electrically conductive carbon fiber fleece, serves as a multi-layered "sandwich" for space heating and drying in a high vacuum. A special glass coated with a selected nanoceramic to increase emission efficiency is applied to the carbon fiber fleece.

[0005] German patent DE 44 38 870 A1 describes an infrared emitter consisting of one or more elongated resistive elements made of carbon fiber tape. The carbon fiber tapes are located in a capillary cavity within a quartz glass casing, which is evacuated or filled with gas.

[0006] German patent DE 44 47 407 A1 describes a flexible sheet structure as a heat-radiating heating element, wherein the supplied electrical energy is converted into long-wave infrared radiation using fibrous or filament-like carbon modifications. In particular, a flexible layer composite is used, in which a mechanically resilient fiber web consisting of electrically conductive fibers with a disordered arrangement of fibers in the form of a carbon fiber fleece is employed, onto which a further dielectric textile cover layer is applied. The cover layer is needle-punched to the carrier layer.

[0007] DE 200 14 518 U1 discloses an infrared radiator arrangement according to the preamble of main claim 1. In particular, this document discloses a heating element in the form of a flat radiator with high heat storage capacity, e.g., in the form of a stone or marble slab, which can be heated by means of a heating conductor arrangement. The heating conductor arrangement comprises a flat carbon fiber strip which, by means of an interposed electrically insulating plastic film, is fixed to the radiator in planar contact with it and is also covered planarly by means of a thermal insulation plate.

[0008] DE 20 2007 002 621 U1 discloses an infrared emitter which consists of several independent carbon fiber conductors alloyed in silicone sheathing.

[0009] DE 20 2007 011 528 U1 discloses a universal device for intensifying the absorption of infrared waves in bed and therapy areas, wherein the attachment of the device to a mattress structure is achieved by a device in the form of a Velcro strap or suitable connecting material.

[0010] JP H08-98 896 A discloses a chair with a heating function that can warm the human body comfortably, evenly, and quickly. The chair has a recess in the seat or backrest. A flat heating element is formed within the recess. Furthermore, an air-permeable element covers the opening of the recess, and an excitation device is provided for activating the flat heating element.

[0011] Infrared radiator arrangements of this type have the disadvantage that the radiation profile they generate cannot be changed as flexibly, either in terms of spatial distribution or temporal variation, as is desirable for effective heat applications using infrared radiation. For optimal effectiveness of infrared radiation on the human body, it is desirable that specific body parts (e.g., shoulder, hip, spine, etc.) can be irradiated with different intensities. Furthermore, it may be necessary to vary the radiation intensity over time during the course of a treatment.

[0012] The above-mentioned infrared emitter arrangements are unsuitable for use in heating applications, as local spatial and temporal variations of the generated beam profile are hardly possible when using them.

[0013] It is therefore an object of the present invention to provide an infrared emitter arrangement, in particular for a low-temperature infrared cabin, in which the radiation profile of the emitted infrared radiation better meets the application requirements, especially in connection with the irradiation of the human body.

[0014] In the following, a low-temperature infrared cabin shall be understood to be a cabin in which a thermally neutral ambient temperature of 28°C to 37°C, preferably 30°C to 35°C, prevails for an unclothed, resting person.

[0015] To solve this problem, the invention provides an infrared emitter arrangement according to the subject matter of main claim 1. In particular, the infrared emitter arrangement according to the invention comprises, in a first aspect, a support element and at least one electrically conductive heating conductor held on the support element, wherein the support element is a flexible holding element made of electrically insulating plastic material and the at least one heating conductor comprises a bundle of several flexible heating conductors. Several heating conductors formed from bundles of carbon fibers are arranged at intervals from one another on the holding element and are provided with electrical connection elements, either individually or in several groups of at least two heating conductors. Furthermore, the infrared emitter arrangement comprises a selection means for selectively choosing the connection elements to be energized.

[0016] By selectively energizing individual heating conductors or groups of heating conductors, it is possible to modify the spatial radiation profile of the infrared radiation generated by the heating element in a spatially, locally, and temporally variable manner. The selection mechanism can be part of a more complex control system that includes electronic circuits and / or a software program.

[0017] A key advantage of the proposed solution is that by providing connection elements for each individual heating conductor or for several predetermined groups, the heating conductors can be individually, i.e., independently, powered. This allows the infrared radiation profile generated by the heating conductor to be varied spatially with a high degree of flexibility. In particular, when used in conjunction with an infrared irradiation device and a low-temperature infrared cabin, this makes it possible to expose specific sections of the human body to different irradiation intensities. Furthermore, with the use of a suitable control device, the generated radiation profile can also be adjusted temporally with a very high degree of flexibility to meet the requirements of heat treatments.

[0018] Preferably, the heating conductors are arranged essentially parallel to each other on the flexible holding element. This simplifies both the manufacturing and the electrical wiring of the heating conductors using the connection elements.

[0019] In a second aspect, the infrared emitter arrangement comprises a support element and at least one electrically conductive heating conductor held on the support element, wherein the support element comprises a flexible holding element made of electrically insulating plastic material and the at least one heating conductor comprises a bundle of several flexible carbon fibers. The at least one or more heating conductors formed from bundles of carbon fibers are arranged on the holding element such that sections of the heating conductor(s) run in pairs at a distance from each other and substantially parallel to each other, and the distances between at least two adjacent pairs of sections are different.

[0020] By varying the distance between paired sections of the heating conductor(s), the radiation profile of the emitted infrared radiation is determined during the manufacturing of the infrared emitter assembly. In this way, the human body, positioned at a specific distance from the infrared emitter assembly, can be irradiated with varying radiation intensities in different areas. This allows, for example, a particularly high radiation density to be generated in areas of the body with pronounced musculature (e.g., along the sides of the spine), which require strong blood circulation.

[0021] Furthermore, it is advisable to equip the heating conductors, either individually or in groups of at least two, with electrical connection elements in an edge area of ​​the flexible holding element. This allows for individual power supply to the heating conductors.

[0022] Preferably, at least one heating conductor is attached to the mounting element. This attachment is preferably achieved by gluing the heating conductor to the flexible mounting element, particularly by means of an adhesive layer.

[0023] A preferred retaining element is a fabric into which at least one heating conductor is woven. This variant is particularly suitable when highly precise parallel alignment of the heating conductors at precisely defined distances is required.

[0024] Furthermore, it is advisable to coat the entire surface of the holding element with a layer of mineral sand, particularly lava sand, covering at least one heating conductor. The use of lava sand ensures optimal transfer of thermal energy into the body and a resulting continuous and slow increase in core body temperature.

[0025] Furthermore, the holding element is preferably coated over its entire surface with a top layer, in particular a lacquer top layer or an impregnated lacquer-carbon fiber fabric. The use of a top layer improves the external optical impression of the infrared emitter arrangement according to the invention. Preferably, the top layer is designed to be easy to clean, i.e., it has a smooth surface structure.

[0026] Furthermore, it is advantageous to mount the flexible holding element on a curved support element. This provides sufficient rigidity to the infrared emitter assembly for practical applications, while the curved design of the support element allows for ergonomic optimization of the infrared emitter element with regard to the body parts to be irradiated (e.g., the upper body).

[0027] In a further preferred embodiment, shielding elements for blocking infrared radiation are arranged on the holding element or at a distance from the holding element in the direction of radiation. In this way, certain parts of the human body can be excluded from exposure to infrared radiation.

[0028] In a third aspect, the present invention relates to an infrared irradiation device comprising at least one infrared emitter arrangement according to the invention, wherein the flexible holding element of the at least one infrared emitter arrangement is segmentally stiffened by means of at least one support element. The infrared irradiation device is particularly suitable for irradiating larger areas of the human body with infrared radiation, since the use of the infrared emitter arrangement in conjunction with one or more support elements allows for a large-area ergonomic adaptation of the infrared emitter arrangement to the body parts to be irradiated. However, even when used for irradiating smaller areas of the human body, the infrared emitter arrangement according to the invention can achieve an improved ergonomic adaptation of the infrared emitter arrangement to the body areas to be irradiated.

[0029] Preferably, the support elements are designed as horizontally extending support strips. This significantly simplifies the manufacture and assembly of the infrared irradiation device without compromising the ergonomic adaptation of the infrared emitter arrangement to the body parts being irradiated.

[0030] Furthermore, it is advantageous for the support elements to each carry backrest segments that define a leaning contour in the direction of and at a distance from the infrared emitter arrangement. The backrest segments support the body parts to be irradiated at a well-defined distance from the infrared emitter arrangement.

[0031] Preferably, the flexible retaining element is reinforced, at least in the areas between the stiffening support element, by an additional layer of flexible plastic. This further increases the mechanical stability of the infrared emitter element.

[0032] It is advantageous for the support elements to be attached to a bracket in a way that allows for elastic deflection perpendicular to the holding element. This further improves the ergonomics of the device.

[0033] In a fourth aspect, which can also be used in previously described embodiments, the present invention relates to an infrared irradiation device with at least one infrared emitter arrangement, wherein the infrared irradiation device further comprises a plurality of elongated mounting plates for attachment to a support structure, which are arranged longitudinally next to each other, in particular parallel to each other. At least one infrared emitter arrangement extends transversely over at least two adjacent mounting plates and is mounted on the mounting plates for segmental stiffening; furthermore, backrest segments are mounted on the mounting plates such that they define a leaning contour on both sides of the infrared emitter arrangement.

[0034] The use of multiple mounting plates enables a modular design of the infrared irradiation device. In particular, the mounting plates of the infrared irradiation device according to the invention are attached to a common mounting structure, while the flexible mounting element of the infrared emitter assembly is indirectly attached to the mounting structure by means of the mounting plates. The geometric arrangement of the mounting plates can be such that they are already optimized with regard to their ergonomic orientation. Due to the use of a flexible mounting element, the infrared emitter assembly can be easily adapted to different geometric arrangements of the mounting plates.

[0035] Preferably, the backrest segments are arranged such that the leaning contour they define partially covers the emission area of ​​the infrared emitter arrangement. In this way, the backrest segments automatically act as a contact guard, preventing a user of the infrared irradiation device from accidentally coming into contact with the infrared emitter arrangement.

[0036] Furthermore, it is advisable that at least some of the mounting plates be equipped with a touch protection element that spans the entire infrared emitter assembly. Suitable touch protection elements include, in particular, [list of suitable elements would go here].

[0037] The protective elements can be attached to the mounting plate on both sides of the infrared emitter assembly. Alternatively, they can be attached to adjacent backrest segments mounted on the mounting plate on both sides of the infrared emitter assembly. These protective elements also prevent users of the infrared irradiation device from accidentally coming into contact with the infrared emitter assembly.

[0038] In a preferred embodiment, the retaining plates are elastically deflected and attached to the support structure. This allows the position of the backrest segments attached to the retaining plates to be optimally adjusted to the parts of the human body to be irradiated.

[0039] The invention is explained in more detail below with reference to preferred embodiments and the accompanying figures. Fig. Figure 1 shows a first embodiment of an infrared emitter arrangement according to the invention. Fig. Figure 2 shows a second embodiment of an infrared emitter arrangement according to the invention. Fig. Figure 3 shows an alternative wiring example according to the invention for the first and second embodiments. Fig. Figure 4 shows another alternative wiring example for the first and second embodiments. Fig. Figure 5 shows an alternative arrangement of the heating conductors on the holding element of the first and second embodiments in the form of a fabric. Fig. Figure 6 shows a side view of a variant of the infrared emitter arrangement according to the invention. Fig. Figure 7 shows a shielding element of an infrared emitter arrangement according to the invention in the form of a shielding grid. Fig. Figure 8 shows a perspective view of an embodiment of an infrared irradiation device according to the invention. Fig. Figure 9 shows a side view of the embodiment of Fig. 8. Fig. Figure 10 shows a perspective view of a further embodiment of an infrared irradiation device according to the invention. Fig. Figure 11 shows a side view of the embodiment of Fig. 10.

[0040] The Fig. Figure 1 shows a general infrared emitter arrangement, designated 1, for an infrared irradiation device. The infrared emitter arrangement 1 comprises a flexible mounting element 3 made of electrically insulating plastic material. A plurality of flexible heating conductors 5 are arranged parallel to one another on the mounting element 3. The heating conductors 5 are bonded to the flexible mounting element 3 at substantially identical intervals by means of a layer of flexible resin. The electrical connection for energizing the heating conductors is made by means of the connection elements 7 in the form of copper plates attached to a side edge of the flexible mounting element 3, onto which the heating conductors 5 are pressed by means of an insulating strip 10. Three adjacent heating conductors are connected to the same connection element 7. In this way, individual energizing of the heating conductors 5 is possible with reduced wiring effort, resulting in the desired inhomogeneous radiation profile with respect tothe infrared radiation emitted by the infrared radiator arrangement. Such a configuration is suitable, for example, when parts of the back of the human body are to be irradiated with different intensities.

[0041] A common ground connection 8 is provided on the side of the flexible holding element 3 opposite the connection elements 7. The connection elements 7 are electrically and mechanically connected to a terminal block 9. The terminal block 9 is connected to a selection device 11, which enables the selective control of the heating conductors 5 for selective energizing. The selection device 11 is part of a control mechanism that includes electronic circuits and / or a software program.

[0042] In a variant of the first embodiment, it is possible to determine the number of available connection elements as desired in relation to the number of available heating conductors 5, depending on the application requirements.

[0043] In another variant of the first embodiment, the ground connection 8 is replaced by connection elements 7.

[0044] In another variant, crimp sleeves can be used instead of copper plates in conjunction with the insulating strip.

[0045] In another variant, the heating conductors are not held on the flexible retaining element by means of resin, but are held “sandwich-like” between the retaining element made of flexible plastic and an additional retaining element made of flexible plastic.

[0046] In another variant, instead of a layer of flexible resin, the heating conductors 5 are surrounded by flexible plastic and attached to the flexible holding element 3 by means of the surrounding flexible plastic.

[0047] The Fig. Figure 2 shows a second embodiment 1a of an infrared emitter arrangement for an infrared irradiation device. The second embodiment differs from the first embodiment in several respects.

[0048] Distances between two pairs of adjacent heating conductors 5a. In Fig. In this embodiment, the distance D1 between two adjacent heating conductors 5a arranged in a central area of ​​the holding element is greater than the distance D2 between two adjacent heating conductors 5a located at the edge of the holding element 3a. By varying the distances between adjacent heating conductors 5a, it is also possible in this embodiment to generate a spatially inhomogeneous beam profile of the infrared radiation emitted by the infrared radiator arrangement 1a.

[0049] The type of generated beam profile is determined by the arrangement geometry during the manufacturing of the infrared emitter assembly. For the infrared emitter assembly of the second embodiment, a single common connection element 7a and a ground connection 8a are also sufficient to implement the electrical wiring of the heating conductors 5a.

[0050] In Fig. Figure 3 shows a variant of the second embodiment 1b. In this variant, the heating conductors 5b are mounted on the flexible holding element 3b, with each heating conductor being guided such that both of its ends are provided with a connection element 7b on the same side of the flexible holding element 3b. In this way, the electrical connection of the heating conductors can be made entirely on one side of the flexible holding element 3b. In this variant, arrangement geometries of the heating conductors with varying distances (D1 or D2) between adjacent sections are implemented. However, other arrangement geometries, for example with identical distances, are also possible.

[0051] Fig. Figure 4 shows a further variant of the second embodiment of the infrared irradiation device 1c according to the invention. In this variant, the heating conductor 5c is arranged meander-like on the flexible holding element 3c, with the distance between adjacent sections of the heating conductor 5c varying. The distance D1 between two adjacent sections of the heating conductor 5c in an edge region of the flexible holding element 3c is smaller than the distance D2 in a central region of the flexible holding element 3c. By varying the distances between adjacent heating conductors 5c, it is also possible in this variant to generate a spatially inhomogeneous beam profile of the radiation emitted by the infrared emitter arrangement 1c.

[0052] In another variant, it is possible to combine the first and second embodiments as well as their variants with regard to the number and arrangement geometry of the heating conductors, connection of the heating conductors to connection elements, grouping of the heating conductors to connection elements and variation of the distance between pairs of adjacent heating conductors.

[0053] In Fig. Figure 5 shows a variant 1d of the first and second embodiments of the infrared emitter arrangement according to the invention, in which the flexible holding element 3d is designed as a fabric into which a plurality of heating conductors 5d are woven running parallel to each other. This variant is particularly suitable if the heating conductors are not to be attached to the flexible holding element by means of an adhesive.

[0054] In another variant of the first embodiment, the infrared emitter arrangement 1e is as shown in Fig. Figure 6 shows the component mounted on a curved stiffening plate 13 in a side view. Metallic materials are particularly suitable for the stiffening plate 13, as they prevent unwanted emission of infrared radiation in the rear direction. The geometry of the stiffening plate 13 can be chosen according to the requirements of the application.

[0055] In another variant, the infrared emitter arrangement is, as also in Fig. 6 shown, coated with a layer of lava sand 15, which covers the heating conductor 5e completely.

[0056] In another variant, the infrared emitter arrangement is as in Fig. Figure 6 shows the infrared emitter assembly coated with a lacquer topcoat 17. Alternatively, the infrared emitter assembly can also be coated with an impregnated carbon fiber fabric. The lacquer topcoat 17 improves the external optical appearance of the infrared emitter assembly 1e to an observer.

[0057] In a Fig. In the variant shown in Figure 7, the infrared emitter arrangement 1f is supplemented by a shielding element in the form of a shielding grid 19, so that certain radiation areas of the radiation emitted by the infrared emitter arrangement are shielded by radiation-impermeable surface elements 21, which are attached to the shielding grid 19.

[0058] In the following, all directional information refers to the operating position of the described device.

[0059] The Fig. 8 and Fig. Figure 9 shows an infrared irradiation device 100 according to the invention, comprising an infrared emitter arrangement 1 according to the invention, in perspective and side views, wherein the flexible holding element 3 extends over a plurality of grid-like arranged support elements 101 and is stiffened onto them. Each support element 101 is elastically deflectable and attached to a holding structure 105. Furthermore, each support element 101 comprises a spaced-apart backrest segment 103. A sufficiently large gap is provided between each pair of adjacent backrest segments 103 so that infrared radiation can pass through the gaps to the body parts to be irradiated.

[0060] The support elements 101 of the infrared irradiation device according to the invention can be aligned so that the backrest segments 103, which form a backrest contour, rest against the parts of the human body to be irradiated (e.g., the human back). In this way, the infrared emitter arrangement 1 is positioned at a uniform distance from the body surface across the entire area to be irradiated. This prevents the intensity of the infrared radiation striking the body surface from varying due to distance. The backrest segments 103 thus provide support for the human body.

[0061] The Fig. 10 and Fig. Figure 11 shows a further embodiment of an infrared irradiation device 100a according to the invention, which is particularly suitable for irradiating the human spine and its immediate surroundings. In this embodiment, six mounting plates 102a are arranged in a row, parallel to one another and to each other, and each is elastically deflected from the mounting structure by means of a plurality of spring elements. The flexible mounting element 3 of the infrared emitter arrangement 1 extends vertically across all mounting plates in a region central to the horizontal and is attached to them. The flexible mounting element 3 of the infrared emitter arrangement 1 is reinforced by an additional layer of flexible plastic 107a. Four backrest segments 103a are attached to each mounting plate 102a.The width of the infrared emitter arrangement 1 is small in relation to the backrest width of the infrared irradiation device 100a and is, for example, 5 cm to 20 cm. In the exemplary embodiment, the surface contour 105k of the support structure 105a is essentially adapted to the surface contour of the human back. However, other geometries are also conceivable. Ergonomic fine-tuning to the human back is achieved by the elastically deflectable mounting plates 102a attached to the support structure 105a, which are deflected from their rest position when the back is leaned against the backrest segments 103a. Since the infrared emitter arrangement 1 is attached to the mounting plates, the distance of the infrared emitter arrangement 1 to the surface of the human back is also adjusted simultaneously when the human back is leaned against it. The [missing information] is particularly suitable for use as an infrared emitter arrangement 1. Fig. 2, Fig. 3 to Fig. 4 variants shown.

[0062] Both the number of retaining plates and the number of backrest segments can be varied in further variants of the embodiment.
