Description

Portable heating device

The invention relates to a portable heating device according to the preamble of patent claim 1.

Portable heating devices are known which are intended to heat small rooms and/or camping tents.

As a rule, use portable heating devices that have a gas heater, a liquid gas as fuel. Since gas combustion produces less carbon dioxide than other fossil energy sources and pollutant-forming components such as sulfur are practically non-existent, gas heating poses little danger to people and the environment. That is why gas heating is often used outdoors used, such as for heating camping tents, usually the exhaust gases from the gas combustion are supplied as thermal heat to an interior, whereby the interior is heated exclusively by the discharged exhaust air.

The disadvantage of this is that when liquid gas is burned and there is insufficient oxygen supply, not only is carbon dioxide and water formed, but also carbon monoxide is formed, which poses a risk to the health of the people in the interior.

The object of the invention is therefore to specify a portable heating device of the type mentioned at the outset, with which the disadvantages mentioned can be avoided, with which an interior area can be heated efficiently and with which there is no danger to the people in the interior area.

According to the invention, this is achieved by the features of patent claim 1.

This has the advantage that a robust, lightweight, compact and safe portable heating device can be built with which an interior, in particular an interior of small rooms and / or camping tents, can be easily and efficiently heated, the interior Free of any waste gases of combustion produced during the heating process can be kept and therefore there is no danger to people who are in the heated interior area. As a result, staying in the interior area is significantly more pleasant and safer for people because the interior area can be heated by at least one heat-emitting surface, resulting in a pleasant feel-good climate in the interior area. Due to the heating of the inner area by the at least one heat dissipation surface on the outside of the housing, a rather simple, robust and light construction of the portable heating device can be selected.

The invention also relates to a building, in particular a tent, with a portable heating device according to claim 14.

The dependent claims relate to further advantageous configurations of the invention.

Express reference is hereby made to the wording of the patent claims, which means that the patent claims are inserted into the description at this point by reference and are deemed to be reproduced verbatim.

The at least one heat dissipation surface 8 can preferably be formed from a metal with a high thermal conductivity, in particular from steel, particularly preferably from aluminium, resulting in a high heat dissipation to the environment.

It can preferably be provided that at least part of the housing 3 forms a wall of the combustion chamber 4 . The heating device 1 can be constructed in a particularly simple, compact but nevertheless robust manner, in which case the heat generated during combustion in the combustion chamber 4 can be given off to the at least one heat-emitting surface 8, which means that heat can be given off to the interior area 2 as quickly as possible after the Heating device 1 results.

Particularly preferably, the combustion chamber 4 can essentially be formed by the housing 3 .

Provision can furthermore preferably be made for the at least one heat dissipation surface 8 to have heat exchanger structures, in particular designed as cooling ribs, for enlarging the surface area of the at least one heat dissipation surface 8 . The cooling fins can preferably be horizontal, vertical and/or angled on the at least one heat dissipation surface 8 .

Provision can preferably be made for the heating device 1 to have an air supply line for supplying air into the combustion chamber 4 . The air supply line can in particular be designed as a hose or a tube, with the cross section of the air supply line being able to have different shapes.

It can preferably be provided that the supply air fan 9 air from the Outside 24 in the interior 2 feeds. This results in the advantage that no combustion exhaust gases from the combustion chamber 4 can get into the interior 2 .

Provision can also preferably be made for the supply air fan 9 to supply air from the interior 2 of the combustion chamber 4 . In particular, an air-permeable connection can be arranged between the inner area 2 and the outer area 24 in order to avoid negative pressure in the inner area 2 .

The air-permeable connection can particularly preferably be an insect screen. This results in the advantage that the combustion chamber 4 can be supplied with air from the interior 2 without generating a vacuum in the interior 2 .

Provision can furthermore preferably be made for the supply air fan 9 to be arranged on an underside 10 of the housing 3 . The underside 10 of the housing 3 is the side closest to the bottom of the interior area 2 in the operating state of the heating device 1 .

Continuous operation of electrical consumers can thus be ensured, especially in the outdoor area.

Furthermore, it can preferably be provided that the control device 22 is connected to the supply air fan 9 , with the control device 22 regulating the control of the supply air fan 9 . This results in the advantage that the air flow within the housing 3 can be set precisely and the heat dissipation on the at least one heat dissipation surface 8 in the interior 2 can be regulated.

A protective covering 23 embodied as a protective grid comprises, in particular, a multiplicity of air-permeable openings, the air-permeable openings preferably being ventilation openings for the heat given off on the heat dissipation surface 8 . This results in the advantage that, given a high heat output of the heating device 1 , protection against burns can be ensured, with the heating of the air in the interior area 2 on the at least one heat dissipation surface 8 not being impeded. Furthermore, a portable heating device 1 is more likely to be subjected to shocks during use than a stationary heating device 1, for example due to transport on rough roads or a fall. In this case, portable heating devices 1 are particularly exposed to the risk of being damaged by impacts. The protective covering 23 can thus also protect the heat dissipation surface 8 from damage, because the protective covering 23 is able to absorb the energy caused by an impact or a fall.

The air-permeable protective covering 23 is preferably made at least partially from metal, in particular from steel or aluminum, particularly preferably from a perforated metal sheet, and/or at least partially from plastic.

Alternatively, it can be provided that the air circulation fan 14 includes a suspension device, in particular a hook or a loop, for suspending the air circulation fan 14 in the interior area 2 . As a result, the air in the interior area 2 can be circulated in a particularly advantageous manner, with the air supplied to the protective covering 23 being able to be optimally regulated.

Particularly preferably, it can be provided that the first section of the exhaust pipe 6 is essentially made of metal. Particularly preferably, the through-opening on the protective casing 23 and the air circulation fan 14 can be arranged on the same side of the protective casing 23 .

Provision can preferably be made for the axis of the air circulation fan 14 to be arranged parallel to the upper side of the housing 3 .

Provision can furthermore preferably be made for the exhaust pipe 6 to have a second section, with the second section of the exhaust pipe 6 being formed between the through-opening on the protective covering 23 and the outer area 24 .

Provision can also preferably be made for the gas connection for the gas burner 5 to protrude from the protective covering 23 . As a result, an empty gas cylinder can be exchanged in a particularly advantageous manner without the protective covering 23 having to be removed.

Provision can also be made for the control valve 12 to be led out of the protective covering 23 . This results in the advantage that the portable heating device 1 can be built compactly, with the gas flow through the gas line 11 to the combustion chamber 4 being able to be controlled easily and safely, with the control valve 12 being protected from the heat dissipation on the heat dissipation surface 8 .
