Definitions

  • the invention relates to a flat infrared heating device for heating a body of a user by means of thermal radiation with the features of the preamble of claim 1.
  • This two-dimensional infrared heating device for heating a body of a user by means of thermal radiation basically has three layers, two textile layers being spaced apart from one another by a spacing device made of spacing threads.
  • the first textile layer for generating the heat radiation has electrically conductive threads. This heat radiation heats the second flat textile layer spaced by the spacer threads, which in turn can be brought into contact with the body of a user, as a result of which it can emit its heat obtained from the heat radiation to the body of the user.
  • Another flat infrared heating device is from the DE 199 03 070 A1 known. This also describes in the same way a layer structure which essentially consists of three layers, a first textile layer having electrically conductive threads which emit heat radiation. These heat a second textile layer which is spaced apart from the first textile layer by a spacer device woven from a tangle of spacer threads. The second textile layer warms a user's body when touched.
  • a disadvantage of the prior art is that the known infrared heating devices only generate heat either by radiant heaters placed directly against the body (if no spacing device is provided) or - as in the prior art described above - in Form of conductive heat contacting is introduced into the body. As a result, only limited amounts of energy can be introduced into the body (possibly clothing covering the body), since otherwise there is a risk of burning body surfaces due to the heating device coming into contact with the body. In the prior art described above, burns of the body would thus be caused on contact with the second textile layer if the latter were heated too much by the heat rays.
  • Another disadvantage of the prior art is that pressure points on the body occur when the heating device comes into contact with the body for a prolonged period. Such pressure points inhibit blood flow to the body precisely where heat is applied. An inhibited blood circulation has a negative influence on the heat distribution in the body through the warmed blood.
  • the object of the invention is to provide a generic, flat-shaped infrared heating device for heating a body of a user by means of thermal radiation, in which the problems discussed above are avoided.
  • heat radiation generated by the heat radiator can pass through the through openings and reach the body of a user - possibly over clothing covering the body .
  • the proportion of the passage openings and / or the size of the passage openings in the structure is preferably chosen to be so large that at least 50% (preferably at least 80%) of heat radiation radiated onto the structure in the flat, unloaded state of the structure passes through the passage openings can.
  • This can be easily measured by measuring by means of a sensor for thermal radiation at a defined distance from the structure, how large the intensity of averaged over the structure or over a representative selected partial area of the structure is heat radiation passing through the structure or the partial area, in comparison to the average intensity if the measurement is carried out at the same distance without the structure (100%).
  • the heat radiation can be generated with the flat heat radiator that is used in the infrared heating device. However, this is not absolutely necessary. If a representative partial area is used, it is advisable to choose the area of this partial area such that it corresponds to at least 5 times, preferably at least 10 times the area of an average opening.
  • the infrared heating device is heated over its entire area with uniform output by the at least one area-shaped heat radiator.
  • the infrared heating device has zones, the heating power in different zones being different (possibly also zero).
  • the flat infrared heating device does not have to be flat, but can have a non-flat contour (that is to say, for example, it can be curved in some areas).
  • the heat radiation emitted by the at least one flat-shaped heat radiator When used on the body of a user, the heat radiation emitted by the at least one flat-shaped heat radiator thus arrives at the user's body unhindered, but this at least one flat-shaped heat radiator is spaced apart from the body of a user by the spacing device. It is thus possible to operate the radiant heater at significantly higher temperatures than in the prior art, without exposing the user to the risk of burns from excessive temperatures. Far higher energy levels can thus be generated and can be conducted directly to the body of a user by heat radiation, that is to say without being converted into conductive heat.
  • the heat radiation that occurs is essentially on the surface of the skin Converted (if not covered by clothing) into heat that warms the blood of the user in the skin layers.
  • the blood can thus transport the heat unhindered into the body and thus lead to a warming of the user's body.
  • the structure of the spacing device can be designed with the large number of through openings: It can be provided that the structure is formed by a double-faced textile, preferably a spacer fabric, covering the at least one planar heat radiator on at least one of its sides. It is particularly preferably provided that the double-faced textile is exposed with its side facing away from the at least one planar heat radiator. Such a double-faced textile with an exposed side facing away from the at least one planar heat radiator represents a simple possibility for realizing the invention.
  • the through openings are formed by the mesh of the textile.
  • the structure is formed by a grid-shaped or honeycomb-shaped mat, preferably a plastic mat, which covers the at least one planar heat radiator on at least one of its sides.
  • the passage openings are formed by the grid or honeycomb openings. It can particularly preferably be provided that the grid-shaped or honeycomb-shaped mat is exposed with its side facing away from the at least one flat-shaped heat radiator.
  • the at least one planar heat radiator is designed to be operated with a surface temperature of at least 43 ° C., preferably of at least 50 ° C.
  • the structure and the at least one planar heat radiator are connected to one another, preferably by a flexible frame comprising the structure and the at least one planar heat radiator.
  • a flexible frame can for example be made of a plastic or a rubber material.
  • the at least one heat radiator is designed in the form of at least one heating wire arranged on or in a flat structure (e.g. mat), which runs, preferably meandering, over the flat structure.
  • a flat structure e.g. mat
  • Other shapes or lines of a heating wire over the flat structure or the use of several heating wires are also conceivable.
  • the flat structure should advantageously be bendable in at least one direction.
  • the at least one heating wire runs more densely in an edge region of the flat structure than in a central region of the flat structure in order to achieve a homogeneous radiation distribution. This causes an inhomogeneous temperature distribution on the surface of the heat radiator, which in turn causes a homogeneous heat distribution on the skin of the user.
  • the side of the spacing device facing away from the at least one planar heat radiator is covered with a cover which is permeable to heat radiation, preferably in the form of a network.
  • a cover which is permeable to heat radiation, preferably in the form of a network.
  • design options are also conceivable which are realized by wires, threads or the like, as long as it is ensured that the cover is at least essentially permeable to the heat radiation emitted by the at least one planar heat radiator.
  • the heat radiation generated by the at least one planar heat radiator can be used in a particularly energy-efficient manner and it can be avoided that unused thermal energy is lost to the surroundings.
  • a garment with at least one flat infrared heating device according to the invention and a seat, preferably a car seat or an office chair, with a flat infrared heating device according to the invention.

  • the flat-shaped infrared heating device 1 is attached to a structure 7 of the car seat 6, which can consist for example of a foam.
  • a thermally insulating layer 5 is provided as the first layer, and in a preferred embodiment variant, this thermally insulating layer 5 can additionally have a heat radiation-reflecting coating on the side on which the planar heat radiator 3 is attached (this could, for example, be between the thermally insulating layer Layer 5 and the flat-shaped heat radiator 3) to protect the structure 7 from the heat rays of the flat-shaped heat radiator 3 and to direct the heat rays of the flat-shaped heat radiator 3 in the desired direction (in the direction of a body 2 of a user).
  • a planar heat radiator 3 Arranged on the side of the thermally insulating layer 5 facing away from the structure 7 is a planar heat radiator 3, which is electrically operated (the required electrical connections are not shown since they correspond to the prior art) and is designed to emit heat radiation. This heat radiation passes through the spacing device 4 to the body 2 of a user (here: back area of the user).
  • an optional network 8 is additionally arranged on the side of the spacing device 4 facing away from the heat radiator 3.
  • this network 8 can also be designed as a fabric or other protective layer which is essentially permeable to heat radiation.
  • the spacing device 4 is formed by a structure which is arranged on at least one side of the at least one flat-shaped heat radiator 3 and is normally resilient to pressure on the at least one side of the at least one flat-shaped heat radiator 3, the body 2 of the To space the user from the at least one flat heat radiator 3 and to be able to operate the heat radiator 3 at a higher temperature, which in turn means that a higher amount of energy can be delivered to the body 2 of the user without exposing the body to the dangers of burns.

  • the flat infrared heater 1 is arranged adjacent to the back area of the body 2 of a user.

  • a thermally insulating layer 5 is provided on the side of the heat radiator 3 facing away from the user 2, which layer particularly preferably has a reflective layer for heat radiation.
  • an additional layer of fabric 12 can be provided on the outside 10 of the garment 9, for example for optical reasons, or it can protect the garment with certain functionalities (such as a water-repellent function).
  • the 3a to 3d show different design variants of a spacing device 4.
  • tubular spacing elements 13 are shown in each case, which are open on their upper and lower sides, so that heat radiation can pass through the spacing elements 13 essentially unhindered.
