Variable IR wet room irradiation system

Wet rooms in the spa, especially sauna or bath operation are conventionally operated with an oven, but can also be used with long-wave infrared surface heaters according to http://www.pooldoktor.at/link. php? url = Wellness / infra_individual_cabin_flaechenstrahler.htm. Such far-infrared (IR-C) emissive area radiators are significantly less sluggish to an oven, but still sluggish to shorter-wavelength radiation-emitting dryroom modules according to Heraeus booklet "Magic Heat." These, in turn, are unsuitable for use in wet rooms, especially sauna or bathing ,

It is the object of the present invention to provide space-saving, easily mountable and quickly addressable irradiation units for wet rooms in the intensity and the irradiation direction.

Significantly to solve the problem is a set of interchangeable to a Wellnes module composable in brackets in different positions to each other can be arranged ver and non-mirrored IR emitters and protective tubes; a corresponding arrangement of the IR emitter deviates from a centering in the protective tube or in a power supply in a holder leading panel that holds the IR emitter, protects against moisture, has an electrical power connection and otherwise electrically insulated; in particular an IR irradiation system with an IR-transparent protective body, which substantially encloses the IR radiator, and with the holder is electrically insulating and terminates in respect of spray water and whose holder has a cable duct; this cladding and in particular a cladding which has a reflector and in whose holders different arrangement positions of IR emitter and reflector are given; the holder in particular with a shield against water supply; a module whose protective tube has a maximum diameter of 7 cm; a wellness module especially with a narrower in a wider reflective reflector; and corresponding methods for providing wet rooms.

Solutions to the problem are described in the claims.

Decisive for the present invention is that the radiator sheath and the live parts are protected from moisture, spray and pollution, in particular according to household appliance standard EN 60335-1.

For this purpose, as a solution according to the invention a set of mutually interchangeable and zusammenfübaren to a wellness module brackets, IR emitters and protective bodies was provided, in which one can arrange IR emitter and protective body in different positions to each other. This allows optimal irradiation with few components from any location in a room. In principle, this also allows the arrangement of multiple radiators within a dirt pipe. In particular, however, the positioning of a single radiator, which is particularly suitable for a radiator location, is made possible. Both the spotlights, as well as the protective body can be mirrored or mirrored. This allows a particularly suitable radiation focusing, in particular an optimal utilization of the radiation energy. As a protective body, transparent tubes, in particular made of quartz glass have proven. Quartz glass has high transparency with respect to IR radiation. Ideally, the protective body, the holder and the protected air gap between the protective body and the radiator protect against electrical danger from splashing water or other moisture conditions. For this purpose, a holder which ensures an electrically insulating power supply proves itself.

In this sense, to solve the problem, an IR irradiation system for wet rooms is provided, comprising an IR radiator, an IR-transparent protective body which substantially encloses the IR radiator, an IR reflector, and a holder for the IR radiator and the protective body, which has a cable channel, wherein the protective body with the holder electrically insulating and closes against splash water.

Here, the electrical insulation provides security for the user. On the one hand, splash protection contributes to electrical safety and on the other hand protects internal components against corrosion. In this case, short-wave or medium-wave IR radiators are preferably shielded against electrical contact by spray water.

^■ In this case, the solution of the problem also takes place in which the IR emitter is arranged in a wet shielding covering which holds the IR emitter, electrically connected in a holder and otherwise electrically insulated by the power supply is guided in a holder of the panel , This allows a handsome design without visible cables.

^■ Furthermore, an IR radiator (10) in a protective tube (20) is arranged so that the IR radiator (10) is located well outside the (coaxial) center of the protective tube (20). This brings with it the advantages that firstly a good radiation bundling can be provided and secondly the temperature of the protective tube at the radiation exit surface is reduced and thus contributes to increased safety and improved energy utilization.

^■ A solution is carried out by means of a module which has a protective tube with a maximum diameter of 8 cm, in particular a maximum of 5 cm, and a holder around an IR emitter. Here, with a partially mirrored protective tube with respect to a partially mirrored radiator, a bundling of radiation allows and gained over an external reflector free space.

^■ In particular, there is a solution to the problem, in which a wellness module in an IR emitter is covered, the panel holds the spotlight, protects against moisture, electrically connects and otherwise electrically insulated. Such wellness modules can be used under extended environmental conditions.

^■ In this case, the solution of the problem also takes place in which a wellness module has an IR emitter and two reflectors, of which a reflector for the reflection of IR radiation in the other reflector is arranged, in particular a narrower reflector infrared radiation in one reflected wider reflector. In this way, unwanted irradiance maxima can be avoided.

^■ Furthermore, a cover for shielding an IR radiator is provided which has holders for holding the IR radiator and a reflector, wherein in the brackets of the panel different arrangement positions of the IR radiator and reflector are given that allow different direction of radiation and bundling. This allows a functionally different use in functionally different positions.

^■ The object is also achieved, in which a holder with an electrical connection for an IR emitter and Receiving devices for an IR radiator and a to be arranged around the IR radiator transparent hollow body is equipped and variable recording devices for a radiant heater or the cladding mark the holder. This allows a functionally different use in functionally different positions.

^■ Alternatively, a bracket is provided with an internal cable duct and a wall seal and pipe seal adjacent to the bracket, surrounding the cable duct. This creates safety and corrosion protection.

^■ Also provided for the spotlight and protective cover is a bracket with internal cable channel and a shield against water supply. This ensures safety and corrosion protection.

^■ Furthermore, to set medium or short wave infrared radiators in wet rooms infrared radiators depending on the distance of the objects to be irradiated according to their distance in the holder positioned. This allows a functionally different use in functionally different positions.

^■ The present invention enables a plurality of IR radiators as part of multiple arrays of multiple modules, or in a plurality of panels within a wellness room to use, in the reflectors and emitters depending on the location in the wellness room are positioned differently in the holders. This achieves a good approximation to uniformly uniform irradiation of a body to be irradiated.

An inventive provision of wet rooms by aligning IR modules by each one IR radiator and a protective body per module are arranged in a holder in one of several positions to each other.

Accordingly, damp areas can be equipped according to the invention by each one IR radiator and a reflector per module in a holder in one of several possible positions to each other are arranged and the IR radiator is shielded with a protective body and the holder electrically from the room.

Have proved IR heaters with a heating element in a sheath, in particular a quartz tube with a current feedthrough. Simple radiators are round tube radiators with a metallic heating coil. Also tried and tested IR emitters are carbon emitters, halogen fillers, double tube emitters and surface emitters. The emission maximum is between 0.7 and 4 μm, in particular between 1 and 3 μm. As short- and medium-wave IR emitters are spotlights with an emission maximum in the near infrared (IR-A) and middle infrared (IR-B).

Arrangements with a IR-transparent enveloping body arranged on a holder have proven to be suitable, in particular protective tubes held between two holders, which preferably have a diameter of less than 7 cm, in particular less than 5 cm. Quartz glass protective tubes, together with the trapped air and creepage distances, provide very good electrical insulation and are insensitive to spray even at high temperatures.

Both the sheath of the IR radiator, in particular a Heizleiterhüllrohr, and the IR-permeable lining part, in particular a protective tube, preferably made of the same material, in particular quartz glass and may be partially mirrored inside or outside.

At least one bracket has a cable channel in which an electrical cable can connect the IR emitter to the mains. Preferred materials for the holder are ceramic or plastic.

Wellness modules are modules for use in wellness rooms, especially in sauna or bath operation.

Wet rooms are to be understood as spaces in which high humidity is achieved by considerable amounts of water or water surfaces, in particular by heated water in baths or infusions in saunas.

Reflectors are used to align the infrared radiation. Thus, it is advantageous to use a reflector between an IR radiator and the wall closest to it. In addition, it may be advantageous to apply a second reflector to avoid hotspots at a short beam distance from the irradiation object, so that between the radiation object and infrared radiator another reflector is arranged. In this arrangement, equalization of the radiation for short distances is achieved. This arrangement is special suitable for distances of less than 50 cm to the object to be irradiated, for example for the leg and back area. At distances of less than 30 cm, in particular less than 20 cm, as in the body of a seat or backrest, indirect radiation is even more important.

More preferably, the heating conductor is an aluminum-iron alloy or tungsten filament or a carbon fiber material; if the sheath of the heating conductor is a tube, if the sheath of the heating conductor consists of quartz glass or sapphire, if the sheath is reflective in a subarea for IR radiation, in particular partially mirrored, the sheath seals gas-tightly at the current leadthrough; If the cladding has two holders for holding the radiator, the cladding between the holders comprises a protective tube, sealing the protective tube to the holders, the protective tube has an IR-reflecting region, in particular a partial mirroring, the protective tube is made of quartz glass; are in the cladding multiple arrangement options for the IR emitter formed, the holders have multiple arrangement options for the IR emitter, the holders have several arrangement options for a surrounding the radiator between the brackets pipe.

In the following, the invention will be clarified by way of example with reference to the drawings.

A set off

^■ IR round tube emitters 10 according to Heraeus brochure Magic Heat;

^■ IR round tube emitters 10 with mirror coating 13 according to Heraeus brochure Magic Heat; Quartz glass tubes 20 according to http://www.heraeus-quarzglas.de/HQS1/DEU/HQT/hqt_home.nsf/$frameset/GLL1st;

^■ Quartz glass tubes 20 with mirror coating 23 according to Heraeus brochure Magic Heat;

^■ Reflectors 33 according to Heraeus brochure Magic Heat;

^■ brackets 40 according to the invention are permitted in a sauna room 50 in the infusions, composed at different points in space 50 at different IR radiator modules 60th

FIG. 1 shows an IR emitter which is arranged coaxially and close to the edge within a protective tube 20 and coaxially close to a reflector. To fix this arrangement, the matching holder has 40 recesses for receiving a radiator 10, a protective tube 20 and a reflector 33. The recesses for receiving the protective tube 20 and the Lectors 33 are formed as grooves. The recess for receiving the radiator 10 is a recess with a continuing cable channel. The cable channel extends in the holder 40 to the fastening wall for the intended side. On the wall side of the cable channel is guided by a projecting from the wall side of the bracket pin. Around the pin, a seal 46 is applied between the wall and the holder 40. The cable channel surrounding the pin of the holder 40 is inserted into the cabin wall. The electrical connection 14 of the IR emitter extends from the IR emitter through the cable channel in the cabin wall 55. In the front view of the course of the wells can be seen. The recess for a reflector 33 and its use allows the application of simple quartz glass tubes 20. When quartz glass tubes 20 with mirror coating 23, a reflector 33 is unnecessary. In a holder 40 of Figure 1 made of insulating material, a radiator 10, a protective tube 20 and a reflector 33 can be inserted, position and seal. The radiator is then isolated by the protective tube relative to the outer space, if in addition the exit point of the lying in the holder 40 cable channel is isolated. For this purpose, for example, a sealing pad 46 is provided, which is pressed by means of a screw 45 to the cabin wall 55. In addition, a part of the bracket protruding into the wall provides protection against ingress of liquid that could creep under the seal. The attachment of the bracket 40 to the cabin wall 55 is carried out with a screw 45th

Figure 2 shows a possible external view of an assembly of two brackets 40 and a protective tube 20. The brackets have a symmetry which makes it possible to use identical parts for both sides. The slim shape of this module is advantageous for particularly close corner installation.

In the arrangement according to FIG. 3, both reflectors serve to reverse the direction of the radiation which otherwise would disappear to the rear out of the useful range.

For this purpose, an IR emitter 10 are arranged in a protective tube 20 made of quartz glass and directed one or more reflectors 13, 23 and 33 to the center of the room.

Such an arrangement is suitable for IR emitters which are arranged relatively far away from the irradiated body, such as on the ceiling or an edge on the ceiling. In the vicinity, such as in the seat or a closely spaced wall, such an arrangement should be avoided, as the central irradiation as a hotspot to burns can lead and those from the hotspot more distant body parts are hardly irradiated.

For the close range, an arrangement according to Figure 4, in which the direct radiation of the heating element 11 in the IR radiator 10 is prevented by a mirror 13 or 23 between the heating element 1 1 and the irradiated body. The smaller reflector shields a useful area lying very close to the emitter from excessive radiation intensity and supplies the power that otherwise emanates directly from the emitter to the larger reflector for targeted distribution. With this arrangement, the body is irradiated very evenly. The reflector 13, 23 located between the body to be irradiated and the heating conductor 11 can be arranged inside and outside the cladding tube 12 of the radiant heater 10 or inside and outside the protective tube 20. The body is irradiated by the indirect radiation from a larger reflector 23, 33. If the smaller reflector 13 is arranged in or on the cladding tube 12 of the IR emitter 10, the reflector 23 irradiating the body can be embodied as part of the protective tube wall inside or outside the protective tube 20 or inside the protective tube wall.

An emitter with partially gold-plated cladding tube 12 according to FIG. 5 scatters more strongly than an arrangement of IR emitter and partially mirrored protective tube 20 according to FIG. 6. The arrangement according to FIG. 5 is suitable for medium distances. The gold coating of Figure 5 has essentially only a shielding effect because the bundling effect is limited by the small dimension of the reflective coating.

Due to the advantageous difference in size between heating conductor 11 and reflector 23 according to FIG. 6, the widening of the reflecting radiation is reduced. The temperature load of the mirror layer is lower and both shielding and directivity can be implemented more targeted.

The clearly decentralized arrangement of a radiator 10 in a protective tube 20 according to FIG. 7 reduces the temperature of the portion of the protective tube facing the useful area. With a partially mirrored protective tube, the radiation can be bundled much more strongly than in the case of a central arrangement.

A holder 40 according to FIG. 8 has a plurality of receiving positions 41 for IR emitters 10 within a receptacle 42 for a protective tube 20. By the around the Schutzrohrachse turned Location of radiator 10 and mirroring 23, the bundling of the radiation can be aligned. The central recording position is suitable for frontal irradiation. The lateral positions are suitable as Eckstrahler. The mirrors of the Eckstrahler are preferably aligned, in particular rotated so that they form isosceles segments with the radiator.

Alternatively, 20 different radiator positions are possible with a single recording device 41 for an IR radiator on a turntable in a holder 40 within a protective tube.

In a holder 40 according to FIG. 9, a protective tube 20 can be arranged in 3 positions 42 around an IR emitter 10. The orientation of the bundling is achieved in this example by displacing the protective tube instead of the radiator.

Alternatively, a protective tube 20 arranged in a decentralized manner on a rotary ring can be aligned for directional focusing of the radiation.

In a holder according to FIG. 10, a wall-side reflector 33 is combined with a reflective coating 13 on the cladding tube 12 of the radiator. In this arrangement, the reflective coating 13 of the cladding tube 12 shields the radiation directed directly into the irradiation field by the radiator 10 and deflects it into the reflector 33. The shape of the reflector 33 can be designed depending on the available space such that uniform irradiation in the near field or even strong radiation is possible Bundling for irradiation at very long distances is achieved.

FIG. 11 shows an equipment of a wet room cabin 50 with four corner radiators arranged in wall corners according to FIG. 8 and two local radiators arranged in the rear wall area according to FIG. For the sides of the cabin arrangements according to Figure 8 have been proven, because the corner position generally has a greater distance to the target person and with this arrangement, the alignment of the beam is particularly simple. Arrangements according to FIG. 10 have proved successful in order to avoid excessive irradiation intensities and uneven irradiation of the back of the person outlined. A classic oven and the wet room operation can be operated together with the embodiments of the invention. The corner spotlights are aligned with their mirroring so that the radiation intensity is directed into the sitting position. For this purpose, emitters 10 are arranged in the mirroring opening of the reflective coating 23 in the protective tube 20, the reflective coating 23 being directed into the wall corners. The rearward radiation modules emit light indirectly by mirroring the power of the IR emitter 10 emitted to the center of the room with a reflective coating 13 in the cladding tube 12 onto a wall-side reflector 33, and only then does the predominant radiant power reach the interior space.

In this indirect irradiation occurs a broadening of the radiation intensity for the short distance to the object to be irradiated.
