Description

The invention relates to a seal. Furthermore, the invention relates to a method for producing a seal.

In principle, a seal is used to be able to close an opening in such a way that there can be a reduced transfer of heat and/or media at the sealing point. For example, a seal may be placed between a housing defining a space and an openable closure for access to that space. The seal then reduces heat losses and media losses from the space at a closure point when the closure is in the closed position.

In the case of ovens, for example, it is common to arrange an elastic seal, for example made of silicone, on a part of the oven housing, in particular on an area of the housing surrounding an access opening. In cooperation with an oven door, a cooking chamber of the oven can be sealed off or closed particularly well. A hot air flow and/or heat radiation escaping at the oven door can thus be reduced and/or prevented. However, the disadvantage of such an elastic seal is that its material is temperature-sensitive. For example, a silicone seal can be damaged from a temperature of 300°C. Other elastomers also usually have such a disadvantageous temperature sensitivity.

Therefore, elastic seals can only be used to a limited extent in devices with high temperature requirements. Modern ovens, for example, have what is known as a pyrolysis function, which enables the cooking chamber of the oven to be heated to over 400° C in order to clean it. In such an oven, therefore, the use of the elastic seal described above is not readily possible. For this reason, a so-called glass fiber seal is usually used in pyrolysis furnaces. This is usually a hose braided from glass fiber. The glass fiber has the temperature resistance required for the pyrolysis function. Due to its textile structure, however, the glass fiber seal can only insufficiently seal the oven door and the oven housing from one another. In particular, a hot air flow can easily escape through the structure of the glass silk seal.

In addition, a glass fiber seal can easily be permanently deformed under the action of force. In contrast to the elastic seal described above, the glass fiber seal can permanently deform at least in certain areas after the oven door is closed and then have a dented point, for example. Likewise, unwanted deformations of the glass fiber seal can already occur during assembly, so that the assembly of the seal itself is also made more difficult. This deformation of the glass fiber seal also impairs its sealing ability, as a result of which, for example, a baking oven with a pyrolysis function is sealed only very inefficiently. Due to the permanent deformability, the seal can lose effectiveness over its service life. In order to alleviate these disadvantages, a resilient layer, which for example comprises a knitted stainless steel wire, can be provided under the glass fiber layer. This resilient layer can at least partially support the glass fiber layer and reduce its permanent deformation under the action of force, but the sealing effect of such a seal is unsatisfactory and the seal continues to be permanently and unintentionally deformable under the usual action of force. In addition, a glass fiber seal can only be adapted to complex geometries of the respective sealing surfaces with difficulty and at great expense, in particular due to its low rigidity.

the US 2013/0097937 A1 describes a furnace gasket with an outer jacket of woven glass fibers.

the DE 10 2004 039 434 A1 describes a cooking appliance door seal with a strand made of a highly heat-resistant material, in particular a glass fiber material.

The object of the present invention is to create a seal for applications with high temperature ranges, which is particularly efficient. Furthermore, it is the object of the present invention to provide a method for producing such a seal.

According to the invention, these objects are achieved by a seal having the features of patent claim 1 and a method having the features of patent claim 9 . Advantageous configurations with expedient developments of the invention are specified in the respective dependent claims, with advantageous configurations of the seal being seen as an advantageous configuration of the method and vice versa.

The invention relates to a seal for at least partially thermally sealing a closure and an opening from one another, in particular for sealing an oven door a sealing body which comprises an outside fiber layer and an inside elastic polymer inlay, in particular an elastomer inlay. Such a seal combines the advantages of a conventional elastic seal with the advantages of a glass fiber seal, which can be used, for example, for ovens with a pyrolysis function.

The fiber layer on the outside protects the polymer inlay from high temperatures and can preferably be made of a material that is resistant to high temperatures. Due to the fiber layer on the outside, the seal can also be used, for example, in applications in which the seal is in contact with temperatures that are above the temperature resistance of the material or materials from which the polymer inlay is formed. In addition, the elastic polymer inlay supports the outer fiber layer so that the seal does not permanently deform under the influence of force. For this purpose, the polymer inlay is preferably more elastic than the fiber layer.

The elastic polymer inlay can at least largely prevent a medium from flowing through the seal, for example a stream of hot gas, which is otherwise not possible with a purely fiber layer as the sealing body, or only with great effort, for example a very thick, close-meshed, multi-layered layer.

The seal is therefore suitable overall for particularly high temperature ranges and seals particularly efficiently. For example, the seal can be used without damage in ovens with pyrolysis, at which temperatures of more than 380° C are reached. The cooking chamber can be sealed much better and the overall energy efficiency of the oven can be increased.

In addition, the seal is stiffer than a pure glass fiber seal due to the internal polymer inlay and can therefore be processed and installed particularly easily. The elastic polymer inlay can thus, for example, assume a support function to reduce and/or prevent deformation of the sealing body under the action of force, in particular the action of force during sealing. This prevents, for example, a permanent deformation of the sealing body when an oven door that seals it is closed.

The polymer inlay can preferably be designed as a layer and can then also be referred to as a polymer layer or as an elastic layer made of a polymer material. The polymer inlay can also be designed as an insulating element and thereby causes an additional thermal and/or fluidic seal between the sealing surfaces. The elastic polymer inlay preferably has a closed and/or continuous surface, as a result of which the seal can seal particularly efficiently. The elastic polymer inlay is preferably essentially gas-impermeable and/or fluid-impermeable, as a result of which the seal is particularly efficient.

The elastic polymer inlay is preferably designed to be rubber-elastic. The elastic polymer inlay can in particular be more elastic than the fiber layer. The fiber layer can, for example, be designed to be limp without permanent deformation of the sealing body being able to occur under normal conditions of use. As a result, the fiber layer can be made particularly thin and can therefore be produced particularly cost-effectively. Overall, the seal can be particularly light and small due to the sealing body with the fiber layer and the elastic polymer inlay.

If a particularly temperature-resistant fiber layer is used, it can be heated during pyrolysis of the baking oven to such an extent that self-cleaning can occur at least on its outer surface. As a result, for example, fat that has been drawn into the fiber layer can be removed at least on the surface to such an extent that a user of the oven can no longer see soiling and that fat that has been drawn into the fiber layer sticks opposite fiber layers together. This prevents a weakening of the sealing properties in places where fat normally sticks the fiber layers together. In the case of a hollow glass fiber seal without a polymer inlay, it can be compressed in such a way that opposite sides come into contact on the inside and stick together there due to the grease that has penetrated, causing permanent deformation with a correspondingly reduced sealing effect. Such sticking together of respective areas of the fiber layer is prevented by the polymer inlay.

The inside of the seal can be defined in particular in such a way that it is a side facing away from the respective pairings of sealing surfaces and/or heat sources. In the case of a hollow seal in particular, there can also be a side on the inside which faces the interior space and/or cavity formed by the seal. An outside layer can accordingly be a respective sealing surface pairing and/or side facing heat sources. Likewise, there can also be a layer on the outside which faces away from an interior space and/or cavity.

The fiber layer can preferably be a textile, but it can also be a metal fabric. The fiber layer can be, for example, a woven fabric, a knitted fabric, a fleece and/or a mesh. In general, different fiber layer production processes can be combined with one another to produce the fiber layer.

The seal can be used not only for thermal sealing, but also for fluid sealing, in particular for sealing against a gas flow and/or a liquid flow.

The fiber layer preferably extends along the entire sealing body; in particular, the fiber layer can form the entire radially outer surface of the sealing body. The fiber layer can form an envelope which surrounds the inner elastic polymer inlay on the outside both in the longitudinal and in the circumferential direction. The fiber layer can envelop the polymer inlay radially on the outside. The fiber layer on the outside forms a kind of protective layer for the polymer inlay on the inside. The respective ends of the sealing body can be open and/or not formed by an outside fiber layer. Such end areas of the seal or the polymer inlay in the end areas can be protected from high temperatures by contacting the two ends of the seal with each other. Alternatively, the respective end areas of the polymer inlay can also be covered on the outside by the fiber layer.

In a further advantageous embodiment of the present invention, it is provided that the sealing body is tubular and the polymer inlay is arranged radially on the inside of the fiber layer. The polymer inlay on the inside is then arranged in the hose interior of the sealing body and in particular forms an inside layer of the sealing body. The polymer inlay can extend radially on the inside essentially along the entire longitudinal extent and/or along the entire inner circumference of the fiber layer. As a result, the fiber layer on the outside can be supported particularly well. In addition, a tubular sealing body is a sealing body that is particularly easy to produce and assemble.

According to the invention, it is provided in the seal that the polymer inlay comprises a silicone material, with the polymer inlay preferably being formed from silicone. A silicone material can be food-safe and is therefore particularly suitable for use in the food sector, in particular in an oven seal. The polymer inlay can then also be referred to as a silicone inlay. A silicone material is also a particularly temperature-resistant elastic material, for example the silicone inlay can be temperature-resistant up to approx. 300°C. As a result, the fiber layer can be designed to be correspondingly thin and still offer adequate protection for the polymer inlay. In addition, a polymer inlay made of silicone material can be produced cost-effectively as a silicone hose.

In a further advantageous embodiment of the seal according to the invention, it is provided that the fiber layer comprises glass fiber, at least one basalt fiber, at least one silicate fiber and/or at least one ceramic fiber, the fiber layer preferably consisting of glass fiber and/or one or more glass fibers, basalt fibers, silicate fibers and/or ceramic fibers. Glass fiber can be produced inexpensively and is also harmless when used in the food sector, and it also only has a lower thermal conductivity. Compared to glass fibers, glass fiber offers the advantage that a particularly tight weave can be produced, making it difficult for dirt to penetrate the fiber layer. Basalt fibers and ceramic fibers are particularly temperature-resistant and can also withstand particularly high mechanical loads. At the same time, the fiber layer made of basalt fibers and/or ceramic fibers can be particularly light. Silicate fibers are particularly temperature-resistant and can be produced inexpensively. The fiber layer can comprise a number of different materials and/or fibers in order to be able to adapt them particularly well to the desired requirements.

In a further advantageous embodiment of the seal according to the invention, it is provided that the fiber layer is braided, with the elastic polymer inlay preferably being braided around by the fiber layer. A braided fiber layer can have a particularly well-closed surface in comparison to other fiber layers, as a result of which the sealing efficiency and dirt resistance are particularly high. The braided fiber layer is particularly impermeable to vapour, gas and liquids. Alternatively, the fiber layer can also be woven or knitted, for example, so that the seal can adapt particularly well to the geometries of the respective sealing surfaces under the action of force.

In a further advantageous embodiment of the seal according to the invention, it is provided that the sealing body comprises a resilient intermediate layer arranged between the fiber layer and the elastic polymer inlay, in particular a metallic intermediate layer which is preferably a knitted wire layer. Thereby the sealing body can be particularly insensitive to the effects of external forces, in particular a permanent deformation of the sealing body under the action of force can be prevented particularly well in this way. The resilient intermediate layer can partially take over a structural function of the polymer inlay. As a result, the elastic polymer inlay can be made thinner and/or lighter. As a result, the seal can be particularly light and/or small overall. The overall rigidity of the seal can thus be increased with little effort compared to a seal of the same thickness without a resilient intermediate layer.

The resilient intermediate layer is preferably formed by a high-grade steel wire, which is particularly dimensionally stable and temperature-resistant. For example, the elastic polymer inlay can be surrounded by a braided stainless steel wire, in particular a braided tubular stainless steel wire, which protects the elastic polymer inlay particularly well. In addition to the fiber layer, the resilient intermediate layer can also protect the polymer inlay from mechanical damage, for example from a puncture and/or a cut. This protection is particularly high with a stainless steel wire sleeve braiding.

In a further advantageous embodiment of the seal according to the invention, it is provided that the fiber layer is at least partially impregnated. As a result, the fiber layer can be protected, in particular against mechanical damage and dirt. The seal is particularly robust. At the same time, the impregnation can prevent fraying of the fiber layer during processing of the fiber layer of the sealing body. This is also referred to as cut-resistant impregnation. The fibers can be glued together by means of the impregnation. In addition, the impregnation can also be used to color the seal in a desired color. The fibrous layer can only be impregnated in certain areas, in particular only on the outside, or also in its entirety, for example by immersion in an impregnating liquid.

Alternatively or additionally, a coating can also be provided on the fiber layer. In particular, a coating can be provided on the outside of the fiber layer in order to prevent a medium, in particular a liquid such as heated fat or oil, from penetrating the fiber layer. In addition, the coating can also protect the elastic polymer inlay from high temperatures. The coating is preferably formed from a material that is resistant to high temperatures.

In a further advantageous embodiment of the seal according to the invention, it is provided that the seal has a retaining element, in particular a plurality of retaining elements spaced apart from one another in the longitudinal extension of the seal, by means of which the seal can be fastened. For example, the respective holding elements can be designed as loops, eyelets or hooks. The holding elements can, for example, be attached to the fiber structure; in particular, they can be incorporated directly into the fiber structure during its manufacture. For example, holding elements can be braided and/or woven into the fiber layer. Alternatively, the holding elements can also have a type of thread, by means of which they are screwed into the sealing body. This thread can be designed, for example, as a coiled wire which, when subjected to a rotary movement with the exertion of force, pierces the various layers of the sealing body and prevents the holding element from being subsequently pulled out of the sealing body. The one or more retaining elements enable the seal to be installed particularly quickly, easily and securely, in particular on corresponding fastening elements on one of the sealing surfaces. If the holding element or the holding elements are fastened both to the fiber layer and to the polymer inlay, these can also fix the relative position of the fiber layer and the polymer inlay to one another and thus prevent unwanted displacement.

The invention further relates to a method for producing a seal for at least partially thermally sealing a closure and an opening from one another, in particular for sealing an oven door. This method provides for the provision of an elastic polymer inlay, the polymer inlay comprising a silicone material. A fiber layer is arranged on the outside of the elastic polymer inlay. As a result, a particularly temperature-resistant and, at the same time, particularly efficiently sealing seal can be produced.

In addition, a resilient intermediate layer can be arranged between the elastic polymer inlay and the fiber layer arranged on the outside. For a particularly simple production, the resilient intermediate layer is first arranged on the outer fiber layer or the inner polymer inlay and these two elements of the sealing body are then arranged together on the further element of the sealing body.

In addition, it is possible to combine the different layers - the polymer inlay and the fiber layer, optionally the resilient intermediate layer to be fixed, for example by means of an adhesive bond and/or by means of the holding elements. This reliably prevents unwanted slipping, in particular during assembly, as a result of which part of the polymer inlay can slip out of the fiber layer, for example. The fiber layer can also be provided with an impregnation, which is applied to the fiber layer in a dipping process, for example. The impregnation can be applied to the fiber layer before the fiber layer is arranged on the polymer inlay, or after the various layers have been arranged on one another. For example, the finished sealing body with all its layers can be immersed in an impregnation for impregnating the fiber layer. In the case of such a subsequent impregnation, the impregnation can also cause the different layers to be fixed to one another in a particularly simple manner.

In a further advantageous embodiment of the method according to the invention, it is provided that the elastic polymer inlay is tubular and the fiber layer is formed by braiding the elastic polymer inlay radially on the outside with at least one fiber. In this case, the elastic polymer inlay is braided directly with the fiber layer, optionally after the arrangement of a resilient intermediate layer. As a result, the need to join the polymer inlay into the fiber layer, which would otherwise be necessary due to their separate production, can be saved. The method is particularly inexpensive and fast. In this case, therefore, the sealing body is not produced by inserting a tubular polymer inlay into a tubular fiber layer. In addition, it is particularly easy to ensure that the fiber layer fits very tightly against the polymer inlay. Instead of braiding, other production processes for the fiber layer can also be used in this embodiment of the method, for example a weaving process or a knitting process.

The resilient intermediate layer can preferably also be knitted around the elastic polymer inlay--similar to the above-described braiding of the polymer inlay with the fiber layer--so that the advantages described above can also be realized for the resilient intermediate layer. In this case, too, the fiber layer can then be produced directly by braiding the polymer inlay with the resilient intermediate layer that has already been knitted around.

The method is particularly suitable for producing the seal according to the invention. The features and advantages resulting from the seal can be found in its description, advantageous configurations of the seal being to be regarded as advantageous configurations of the method and vice versa.

Further advantages, features and details of the invention result from the following description of a preferred exemplary embodiment and from the drawing. The features and combinations of features mentioned above in the description and the features and combinations of features mentioned below in the description of the figures and/or shown alone in the figures can be used not only in the combination specified in each case, but also in other combinations or on their own, without going beyond the scope of the leave invention.

It shows:

• 3 in a schematic side view a partially sectioned part of the seal according to FIG 1 .

1 shows a schematic front view of a seal 10 for an oven door, 2 shows this seal 10 partially in a side view. The seal 10 comprises a sealing body 12 which can be arranged on the outside of a housing of a baking oven on a wall which delimits an access opening to the cooking chamber of the baking oven. An oven door in its closed position is brought into contact with the seal 10 in such a way that it at least partially thermally seals a gap between the housing of the oven and the oven door. Alternatively, the seal 10 can also be arranged on the oven door for this purpose.

The seal 10 can, for example, at least partially prevent a stream of hot air from escaping between the closed oven door and the housing of the oven. The cooking chamber of the oven can thus be at least partially sealed off by means of the seal 10 .

The sealing body 12 comprises an outside fiber layer 14, an inside elastic polymer inlay 16 and a resilient intermediate layer 18. The outside fiber layer 14 is designed as a glass fiber tube. The inside polymer inlay 16 is designed as a silicone tube made of a food-safe and elastic silicone. The resilient intermediate layer 18 is designed as a knitted stainless steel wire hose, which is particularly evident in the partially sectioned side view of the seal 10 in 3 can be seen.

The outside fiber layer 14 protects the elastic polymer inlay 16 from high temperatures. The fiber layer 14 consists of a braided glass fiber layer. The glass fiber is heat-insulating and resistant to high temperatures, so that the seal 10 can also be arranged, for example, on a part of the housing of the oven in which an area and/or contact surfaces with the seal 10 reach temperatures of up to 400° C. or more. The fiber layer 14 shields the polymer inlay 16 so that the polymer inlay 16 cannot be damaged by temperature at such high temperatures. As a result, the seal 10 can also be used in baking ovens with a pyrolysis function, without the polymer or silicone components being able to be damaged.

The polymer inlay 16 has a continuous, closed surface along the entire length of the seal 10 . In contrast to a seal, which consists only of a fiber layer and optionally a resilient intermediate layer, this can prevent a hot gas stream from passing through the seal 10 in a particularly reliable manner. As a result, the seal 10 can seal the oven door particularly well. The fibrous layer 14 and/or the resilient intermediate layer 18 alone would be highly gas permeable in comparison.

As in 1 As can be seen, a certain free space is provided between the various layers of the seal 10--ie the fiber layer 14, the polymer inlay 16 and the resilient intermediate layer 18. This increases the insulating effect of the seal 10. In contrast, the seal 10 is particularly dimensionally stable when the layers are in contact with one another.

The elastic polymer inlay 16 and the resilient intermediate layer 18 support the radially outer fiber layer 14 . When a force acts on the seal 10, for example caused by the closed oven door, the entire sealing body 12 is deformed, for example from the 1 shown round cross-section into an oval cross-section. The fact that the fiber layer 14 is supported ensures that the sealing body 12 rests evenly on all of the sealing surfaces. At the same time, when the force acting on the sealing body 12 is removed, for example by opening the oven door, the sealing body 12 automatically returns to the round cross section. As a result, optimal sealing by the seal 10 is guaranteed at all times. In addition, the seal 10 appears to be of particularly high quality, while damage to the seal 10 by the user could be suspected, for example, in the event of permanent deformation. In addition, the rigidity of the sealing body 12 provided by the resilient intermediate layer 18 and the polymer inlay 16 enables a particularly simple processing and assembly of the seal 10.

Like in the 3 recognizable, the fiber layer 14 is braided. As a result, a surface that is particularly closed for a fiber layer can be provided. Fats and other contaminants can only penetrate the fiber layer 14 to a small extent and can also be easily removed from it again by pyrolysis. At the same time, this tightly closed fiber layer 14 protects the polymer inlay 16 particularly well from overheating.

The resilient intermediate layer 18 consists of a knitted stainless steel wire. A knitted layer enables a particularly flexible deformation of the sealing body 12 along its length. For example, such a high-grade steel wire layer can also be stretched. As a result, the seal 10 can be arranged particularly easily, for example in a rectangular groove in the housing of the oven.

As in 1 shown, the sealing body 12 and its individual layers have a substantially round cross-section. Such a cross section is inexpensive and easy to produce. Depending on the required application, the sealing body 12 can also have a rectangular or oval cross section. Complex geometries for a good adaptation to corresponding geometries of the oven door and the oven housing are also possible, in particular also due to the support of the fiber layer 14 by the polymer inlay 16. The fiber layer 14 and/or the intermediate layer 18 can also be provided in tubular form for a cost-effective seal and only the polymer inlay 16 can be adapted to the complex geometry.

In 2 It can be seen that a plurality of holding elements 20 spaced apart from one another in the longitudinal extension of the seal 10 are provided on the sealing body 12 . By means of these holding elements 20, which each form an eyelet on the outside of the fiber layer 14, the seal 10 can be hung on corresponding holding elements of the housing of the oven for simple and quick assembly. The holding elements 20 have for their attachment to the sealing body 12 respective Threaded elements, which are not shown here. By means of these threaded elements, the holding elements 20 can be easily screwed into the respective layers of the sealing body 12 for their attachment.

The seal 10 can be manufactured by simply providing the respective layers already as respective tubular elements and sliding them into one another. The seal 10 can then be cut to the desired length.

Alternatively, however, the tubular polymer inlay 16 can also be provided first. The resilient intermediate layer 18 is then produced around this polymer inlay 16 by knitting one or more stainless steel wires. Subsequently, the polymer inlay 16 and the resilient intermediate layer 18 are surrounded by a fiber layer 14 by braiding with one or more glass fiber fibers. As a result, the additional manufacturing step of sliding the various layers into one another can be dispensed with. It is also possible that two of the three layers - the polymer inlay 16 and the resilient intermediate layer 18 or the fiber layer 14 - are provided as finished parts. Only the resilient intermediate layer 18 or the radially outer fiber layer 14 is then produced by direct manufacturing around the respective radially inner or radially inner layer, for example by knitting or braiding.
