Description

[0001] The invention relates to an element as a wall, ceiling and / or floor of a mobile home or caravan with at least one material composite with an upper and a lower cover layer and a corrugated core made of a metal embedded therebetween.

[0002] Vacuum insulation panels are known to have a core within a sealed, evacuated shell. The core must be capable of being evacuated and able to withstand the air pressure acting on the vacuum insulation panel. The core acts as a support core, which can be made of open-pore plastic foams, microfiber materials, fumed silica, or perlite. Evacuating the panels reduces the overall thermal conductivity of the material by suppressing gaseous heat conduction and convection, as well as by the porosity of the material and the associated suppression of radiant heat transfer. This results in better thermal insulation compared to mass-produced insulation materials such as rigid polyurethane foam or mineral wool.

[0003] DE 20 2004 010 695 U1 discloses a vacuum insulation panel with a gas-tight insulation core covered by a cover layer on each of its main surfaces. The insulation core consists of microporous silica, an aerogel, or an open-pore material.

[0004] GB 730 114 A describes a highly efficient thermal insulation housing structure that incorporates fibers within an evacuated enclosure. The enclosure is primarily made of metal plates.

[0005] DE 297 11 839 U1 discloses an air conditioning element with channels through which gaseous or liquid media are conducted for cooling or heating. The air conditioning element, a fully metallic sandwich, is constructed from a core of corrugated aluminum and cover layers of smooth aluminum strip. The media guides formed between the corrugated aluminum and the cover layers are connected to each other via common channels.

[0006] The invention defined in claim 1 is based on the object of providing an element as a wall, a ceiling and / or a floor of a mobile home or a caravan with a high level of thermal insulation.

[0007] This problem is solved by the features listed in claim 1.

[0008] The element as a wall, ceiling and / or floor of a mobile home or caravan with at least one material composite with an upper and a lower cover layer and a corrugated core made of a metal embedded between them, is characterized in particular by high thermal insulation.

[0009] For this purpose, at least one vacuum insulation panel or vacuum insulation panels are arranged at least in one plane between two material composites or between a material composite and a cover sheet.

[0010] In addition to its high thermal insulation, the element is also characterized by its functionality. At least one composite material ensures the stability of the element. Particularly high stability can be achieved by using two composite materials, with the vacuum insulation panel(s) located between them.

[0011] Vacuum insulation panels, also known as vacuum insulation boards, are panels that utilize vacuum thermal insulation. Essentially, they consist of a sealed shell with a support core that must be evacuatable and withstand the air pressure acting on the vacuum insulation panel. The support core can be made of open-pore plastic foams, microfiber materials, fumed silica, or perlite. Evacuation reduces the overall thermal conductivity of the material by suppressing gaseous heat conduction and convection, as well as by the porosity of the material and the associated suppression of radiant heat transfer. These effects result in high thermal insulation.

[0012] The wave-shaped core of the composite material and the cover layers create ducts that can be used to air-condition the interior of the motorhome or caravan. The composite material or a composite material facing the interior of the motorhome or caravan can be used for this purpose. In conjunction with a fan, air can be directed through these ducts in either a cocurrent or countercurrent flow. Depending on the season, this can be warm or cold air, creating a comfortable climate in the motorhome or caravan. Ducts can be connected to form groups so that only individual areas, such as surfaces of the wall, ceiling, and / or floor, are heated or cooled.

[0013] When using two composite materials, the outward-facing composite material can advantageously be used as the fastening element. For example, an end or end region of a fastening element can be accommodated in the cavities between the cover layers and / or in conjunction with the corrugated core without damaging the vacuum insulation panel or a vacuum insulation panel.

[0014] Advantageously, at least one material composite with an upper and a lower cover layer and a corrugated core made of a metal embedded therebetween and at least one vacuum insulation panel or vacuum insulation panels arranged in at least one plane, which is or are arranged between two material composites or between a material composite and a cover sheet, can be used as an element as a wall, ceiling and / or floor of a mobile home or caravan.

[0015] Advantageous refinements of the invention are presented in the following developments and embodiments. These can develop the element as a wall, ceiling, and / or floor of a mobile home or caravan with at least one material composite comprising an upper and a lower cover layer and a corrugated metal core embedded therebetween, individually or in combination.

[0016] In one embodiment, the composite material can face inwards to air condition the interior of the motorhome or caravan.

[0017] In one embodiment, the composite material can point outwards to stabilize the element.

[0018] In a further development, vacuum insulation panels can be arranged at an angle to each other and / or overlapped in a corner. This, in particular, prevents thermal bridges.

[0019] In one embodiment, the element may have at least one layer of a thermal insulation material.

[0020] In a further development, the floor and / or ceiling can have at least one layer of thermal insulation material. Vacuum insulation panels of the wall overlap the layer of thermal insulation material at least partially in one corner, thus preventing thermal bridges.

[0021] In one embodiment, the composite material, the further composite material, and the vacuum insulation panel or panels are adhesively bonded together to form a sandwich component. This is a simple connection that also ensures a secure connection of the vacuum insulation panel or panels to the composite material. This also allows small vacuum insulation panels to be easily joined and secured between the composite materials, opposite the wall, floor, and / or ceiling.

[0022] In a further development, the composite material, the cover sheet, and the vacuum insulation panel(s) are adhesively bonded together to form a sandwich component. This allows small vacuum insulation panels to be easily joined and secured between the composite material and the cover sheet, even when facing the wall, floor, and / or ceiling.

[0023] In one embodiment, the outward-facing corner, composed of elements arranged at an angle to one another, can have an angle profile that is connected to the elements with adhesive joints and / or connecting elements. The angle profile increases the stability of the motorhome or caravan.

[0024] In one embodiment, the motorhome or caravan can have a frame, with the elements connected to parts of the frame using adhesive joints and / or fasteners. The frame, together with the elements, ensures high stability. At the same time, the construction of the motorhome or caravan is simplified, as their geometry is predetermined by the frame.

[0025] In some embodiments, connecting elements are advantageously rivets or screws.

[0026] In one embodiment, the element may further comprise an air conditioning layer with at least one capillary tube mat in the direction of the interior.

[0027] In one embodiment, the element can furthermore have a heating mat with, for example, at least one heating resistor at least in some areas towards the interior.

[0028] In one embodiment, the element can have a wooden panel at least partially facing the interior. The wooden panel can be part of an interior wooden paneling, thus forming a vapor-permeable wall system. Any humidity that occurs can be partially absorbed and released by the wooden paneling, thus largely preventing condensation.

[0029] An embodiment of the invention is shown in principle in the drawings and is described in more detail below.

[0030] They show: Fig. 1 an element as a wall, ceiling and / or floor of a motorhome or caravan, Fig. 2 an element between two material composites, Fig. 3 a corner design, Fig. 4 a corner design with an angle profile and Fig. 5 an element with a layer of wood.

[0031] An element as a wall, ceiling and / or floor of a mobile home or caravan essentially consists of at least one material composite 1 and at least one vacuum insulation panel 2 arranged in one plane.

[0032] The Fig. 1 shows an element as a wall, ceiling and / or floor of a mobile home or caravan in a basic representation.

[0033] In one embodiment, the element as a wall, ceiling, and / or floor of a mobile home or caravan can have a cover sheet 3, the vacuum insulation panel 2, and a material composite 1, which are arranged from the outside inwards. The material composite 1 has an upper and a lower cover layer and a corrugated core made of a metal embedded between them. The corrugations of the core of the material composite 1 can have various curve shapes such as sine, rectangle, triangle, or sawtooth. The material composite 1 thus points inwards, in particular for air conditioning the interior of the mobile home or caravan. Channels are formed by means of the corrugations, which can be used as flow channels for at least one flowable medium.

[0034] The Fig. 2 shows an element between two material composites 1, 4 in a basic representation.

[0035] In a further embodiment, the element can have two material composites 1, 4. For this purpose, the material composite 1, the vacuum insulation panel 2, and another material composite 4 are arranged and connected to one another from the inside to the outside.

[0036] Instead of the vacuum insulation panel 2, vacuum insulation panels 2 arranged in at least one plane can also be located between the material composites 1, 4 or between the material composite 1 and the cover sheet 3.

[0037] The individual components of the element are advantageously connected to one another by means of adhesive joints, so that a sandwich component is formed.

[0038] The Fig. 3 shows a corner design in a basic representation.

[0039] In a corner composed of elements arranged at an angle to each other, the vacuum insulation panels 2a and 2b touch and overlap, where a represents one element and b represents the element arranged at an angle to it. The other material composites 4a and 4b of the elements abut each other.

[0040] The Fig. 4 shows a corner design with an angle profile 5 in a basic representation.

[0041] The outward-facing corner, composed of elements arranged at an angle to one another, can have an angle profile 5, which is connected to the elements with adhesive bonds and / or connecting elements. The angle profile 5 can be a component of a frame of the motorhome or caravan. Advantageously, the elements have additional material composites 4, which can thus serve as fastening elements without the vacuum insulation panels 2 being damaged by the use of connecting elements such as rivets or screws.

[0042] The Fig. 5 shows an element with a wood layer 6.

[0043] In a further embodiment, the element has an inner wood layer 6 formed from at least one wood panel. The wood panel can be attached to the composite material 1 by means of an adhesive bond.

[0044] In further embodiments, the element can have an air conditioning layer with at least one capillary tube mat towards the interior and / or have a heating mat at least in some areas. QUOTES CONTAINED IN THE DESCRIPTION
