Description

The invention relates to a portable on a body of a user heat device with the features of the preamble of claim 1 and a garment with such a heating device.

A known from the prior art portable heat device is derived from the US 6,550,471 B2 out. This shows a work suit, which has a heater. The heating device is arranged in the back region of the suit and designed as a heat radiator. More specifically, thermal radiation is generated by a catalytic reaction using propane. The heater is spaced from the body of the user by a spacer. More specifically, this heater is attached to an outer layer of the work suit. The heat radiation is coupled through an outlet opening in the back area in the work suit. Inside the suit, a heat exchanger is arranged in front of the outlet opening, which transfers the heat radiation to a tempering medium, which can pass the heat through channels in suit to individual regions or extremities of the user. Alternatively, in the region of the heat exchanger, the heat radiation can be coupled into light-conducting conductors and distributed through them in the suit.

Also, other heat devices that are portable on the user's body are known in the art. These are usually designed as heating mats, which are sewn into a clothing and bear without spacer device directly on the body of the user.

A disadvantage of the prior art is that generated by the above-known heaters only heat either by directly applied to the body radiant heater or in the form of convective heat contacting the body is initiated. As a result, only limited amounts of energy can be introduced into the body, otherwise due to the contact of the heater with the body there is a risk of burning body surfaces. Another disadvantage of the prior art is that arise with a prolonged contact of the heater with the body pressure points on the body. Such pressure points inhibit the circulation of the body just where heat is supplied. Through an inhibited blood circulation, the heat distribution in the body is adversely affected by the heated blood.

The object of the invention is to provide a generic heating device and a garment with such a heating device, in which the disadvantages of the prior art described above are avoided.

This object is achieved by a portable thermal device having the features of claim 1 and a garment having such a portable thermal device. Advantageous embodiments of the invention are defined in the dependent claims.

According to the invention, the at least one heat radiator is spaced by a spacing device from an outlet opening facing the user, wherein the outlet opening is at least partially surrounded by a contact surface which can be placed on the user's body and the space between the at least one heat radiator and the support surface is at least in the Region of the outlet opening is at least substantially empty, so that at least substantially unhindered reaches the user in operation emitted by the heat radiator heat radiation.

When used on the body of a user, the heat radiation emitted by the at least one heat radiator thus reaches the body unhindered of the user. It is possible to operate the radiant heater at much higher temperatures than in the prior art, without the user being exposed to the risk of burns due to excessive temperatures. Far higher energy levels can thus be generated and directed by heat radiation directly, ie without conversion to convective heat, on the body of a user. The incident heat radiation is essentially converted to heat on a user's skin surface which heats the blood in the skin layers.

There are no blood pressure inhibiting pressure points on the body of the user. The blood can thus transport the heat unhindered into the body and thus lead to a warming of the body of the user.

For example, it can be provided that the support surface is arranged on the spacer device and is preferably formed by a section of a lateral surface of the spacer device. In this embodiment, the spacing device bears against the user's body, wherein the support surface is preferably formed at least in sections by the lateral surface of the spacing device.

Particularly preferably, it is provided that the spacing device and a base body is arranged integrally on or in which the heat radiator is arranged, preferably in the form of a trough. It may be provided in the case of the formation of the base body as a trough that the at least one heat radiator is integrated in the bottom of the tub or disposed on the bottom of the tub.

The opening of the trough can be aligned in the direction of the body of the user, wherein the opening of the trough forms the outlet opening and the lateral surface of the trough forms the spacing device.

It can be provided independently of the one-piece design of the base body and the spacing device in the form of a trough, that the heat radiator is designed as a base body or that the heat radiator is arranged on the base body, is placed on this or incorporated into this.

In a preferred embodiment, it can be provided that the spacing device is designed in the form of a web, preferably circumferential, arranged on the main body.

In a preferred embodiment it can be provided that the at least one heat radiator is designed in the form of at least one heating wire, which preferably runs meandering over the surface of a mat. Other shapes or lines of a heating wire over a surface are conceivable.

It can be provided that the at least one heating wire runs more densely in an edge region of the mat than in a central region of the mat in order to achieve a homogeneous radiation distribution. This causes a inhomogeneous on the surface of the heat radiator temperature distribution, which in turn causes a homogeneous heat distribution on the skin of a user.

Preferably, it is provided that the outlet opening is covered with a heat radiation permeable cover - preferably in the form of a network - covered. As an alternative to the use of a network, it is also conceivable to design possibilities which are realized by wires, threads or the like.

It is particularly preferably provided that the portable heat device is designed so flexible in at least one selected direction, that while the portable heat device is adaptable to a user's body shape, but the spacing device holds the heat radiator away from the exit port. This is particularly useful for the user's comfort and optimal heat input because the user's body does not have to adapt to the portable heat device, but can adapt to the user's body.

Furthermore, it can be provided that the heating device is designed to be elongated for heating a back region of the user and that extends at least one selected direction in the longitudinal direction of the heating device.

Furthermore, protection is sought for a garment with at least one thermal device according to the invention.

It can preferably be provided that the garment has an outer layer and an inner layer facing a wearer of the garment, and the outlet opening of the heating device is arranged in the region of the inner layer.

It may be provided, for example, that the garment for receiving the heat device on the outer layer has an opening and on the inner layer, only a network is provided, on which the heat device is placed with the spacing device. However, it is also possible that the garment is fully opened so that the spacer device of the warming device can directly contact the user.

It may be provided that the garment for receiving the portable thermal device has an openable and closable pocket so that the portable thermal device is quickly and easily removed from the garment or attachable to the garment.

As a heat radiator, all known from the prior art devices can be used, which emit heat radiation, preferably an IR emitter is used. The energy supply to the heat radiator can either be done via a line or it can be provided directly on the heat radiator or in the heat radiator an energy reservoir. So electric radiant heater can even have a battery and / or be connected via a cable to an external power source. Also, a use of heat storage, which give off heat by a reaction (exothermic reaction) is quite conceivable, for example, reference is made to latent heat storage.

The base body 2 is designed in one piece with the spacing device 3 and has a groove 9 and an opening 10 for cables for receiving the heat radiator 1. Thus, in a subsequent consequence, the heat radiator 1 (which has a flat shape) can simply be inserted into the main body 2 via the groove 9. The energy supply of the heat radiator 1, which may be implemented via a cable, can be guided through the opening 10 to the heat radiator 1. The heat radiator 1 and the heater are arranged on the bottom surface 8.
