    SEALING DEVICE FOR A DOMESTIC ITEM
    DESCRIPTION
    The invention refers to a sealing device for a household item, in particular, for a household appliance. Likewise, the invention refers to a method for manufacturing a sealing device and to a household item, in particular, a household appliance, which comprises at least one sealing device.
    In the technical field of household items and household appliances, a wide variety of sealing devices are used to insulate acoustically or thermally. However, there are situations in which different insulating behaviors are desired. Dishwashing machines, for example, must have thermally and acoustically insulated walls during the washing period in order to avoid heat losses and save energy, while during the drying period thermally conductive walls would be advantageous to reduce The necessary drying time.
    The present invention solves the technical problem of providing a sealing device for a household item, where the sealing device has variable insulating properties. Another technical problem that the present invention solves is to provide a method for manufacturing such a sealing device. Also, the present invention solves the technical problem of providing a household item comprising such a sealing device.
    These technical problems are solved by a sealing device for a household item, a method for manufacturing a sealing device for a household item, and a household item in accordance with the independent claims. In the respective dependent claims, advantageous developments of the invention are specified, where the advantageous developments of the sealing device are to be considered advantageous developments of the method and of the domestic article, and vice versa.
    The first aspect of the invention refers to a sealing device for a household item, in particular for a household appliance, which comprises at least one sealing body with several recesses and which comprises at least one switching means, which is switchable at least between an open state and a closed state, where, at least in the open state, the empties of the sealant body allow a fluid to flow through them and, in the closed state, have an area of

    the cross section smaller than in the open state through which a fluid can flow. Therefore, the sealing device can be switched between an "open" open state, in which a fluid can flow through the drains, and a "partially open" or "closed" closed state, in which, compared to in the open state, less fluid can pass through time or at least essentially no fluid can pass through the drains In general, the first and the closed state refer to equal or at least comparable fluid flow conditions. The sealing device according to the invention can be switched between at least the first and the closed state, thus modifying the possible flow rate of said fluid.Therefore, the sealing device can be used, for example, in the context of a dishwashing machine. washing period, the sealing device is switched to the closed state to ensure good thermal and acoustic insulation During the drying phase of the dishwashing process, the device The sealant can be switched to the open state, thus allowing hot steam to flow through it and, therefore, drying times are reduced. Other applications are also conceived, for example, a porous gas burner that allows the flame to pass through the sealing device in the open state and which can be closed by switching the sealing device to the closed state in order to avoid gas leaks or The flame causes damage. The fluid can in general be a liquid, a suspension, a dispersion and / or a gas.
    In an advantageous development of the invention, it is envisioned that the sealant body is at least partially composed of an aughetic material and that the switching means is configured to change the size of the sealant body to commute between the first and the closed state. The aughetic materials usually have a negative Poisson coefficient. When stretched through the switching means, the sealing body thickens perpendicularly to the applied force, thereby enlarging the cross-sectional areas of the drains and allowing greater flow rates of the fluid. Therefore, the use of an aughetic material is a simple way of providing a sealing body with an easily variable flow rate. The switching means may be configured to apply a mechanical displacement of the sealant body, for example, through pistons, pinions and zippers, or the like, to stretch or relax the sealant body in order to switch between the first and the state closed. Alternatively or additionally, the switching means may be configured to induce thermal stress in order to change the size of the sealant body.

    In another advantageous development of the invention, it is envisioned that the aughetic material is a polyether foam, in particular, with an average pore size between 0.4 mm and 0.8 mm, for example, 0.40 mm, 0 , 45 mm, 0.50 mm, 0.55 mm, 0.60 mm, 0.65 mm, 0.70 mm, 0.75 mm, and / or with a volumetric density of between 20 kg / m3 and 40 kg / m3, for example, 20 kg / m3, 21 kg / m3, 22 kg / m3, 23 kg / m3, 24 kg / m3, 25 kg / m3, 26 kg / m3,
    27 kg / m3, 28 kg / m3, 29 kg / m3, 30 kg / m3, 31 kg / m3, 32 kg / m3, 33 kg / m3, 34 kg / m3,
    35 kg / m3, 36 kg / m3, 37 kg / m3, 38 kg / m3, 39 kg / m3, 40 kg / m3. The polyether foam can be, for example, "RP30048 Richfoam Polyether", from Carpenter.
    In another advantageous development of the invention, it is envisaged that the sealant body comprises several recesses, where at least part of the recesses is provided at least one closure body, where the closure bodies allow fluid to flow through the recesses in the open state and, in the closed state, close the emptyings at least to a large extent. In this way, the sealing device can be designed in a manner comparable to an arrangement of spherical valves. In the open state, the sealing body forms a continuous solid phase, while the empties form a continuous gas phase. In the closed state, the dumps form a discontinuous gas phase due to the closing bodies. Depending on the desired characteristics of the flow of passage, it can be provided that only one closing body is arranged in each emptying. As an alternative, it can be provided that one or more closing bodies are arranged only in some of the recesses. Alternatively, it can be provided that more than one closing body is arranged in several or in all the emptyings.
    In another advantageous development of the invention, it is envisioned that the closing bodies are at least partially composed of a magnetic material, in particular steel, and that the switching means is configured to move the closing bodies by means of a magnetic field in the state open to a first position, in which the emptyings are not covered at least partially, and / or in the closed state to a second position, in which the emptyings close at least to a large extent. Therefore, the closing bodies can be moved together without contact by a magnetic field to switch the sealing device between the first and the closed state. It can be provided that the magnetic field is only used to move the closing bodies in one of the states and that the closing bodies move to the other position without there being a magnetic field to bring the sealing device to the other state, for example, as consequence of gravity. Alternatively, the magnetic field can be used to move the closure bodies between the first and second positions. A suitable material for the closing bodies is, for example, the
    5
    10

    25
    30
    AISI 430 (ferritic), AISI 630 (precipitation hardening) or 420 (martensitic) steel. Steel is preferred in many applications given its resistance to corrosion. However, other magnetic materials can generally be used additionally or alternatively to steel.
    In another advantageous development of the invention, it is envisioned that the closing bodies are configured as switching means and that, by their change in volume dependent on pressure and / or temperature, be switchable between the open state and the closed state. In other words, it is envisaged that, thanks to their inherent properties, the closing bodies will function as switching means, so that the sealing device can be moved between the at least two states by changes in pressure and / or temperature in the surrounding area. This can be implemented, for example, by the use of different materials with thermal expansion coefficients sufficiently different for the closing bodies and the sealing body to vary the cross-sectional area of the recesses. The closure bodies may comprise or be composed of, for example, AISI 316 L (austenitic) or AISI 630 steel, which have thermal expansion coefficients of at least 18 * 10-6K-1 at 20 ° C. Other materials, for example, polymeric materials, such as copolymers of ethylene and acrylic acid (EEA), polybutylene (PB), and the like, may have thermal expansion coefficients of between 288 * 10-6K-1 and 450 * 10-6K-1 (EEA) or 424 * 10-6K-1 - 432 * 10-6K-1 (PB) at 20 ° C, and can also be used.
    In another advantageous development of the invention, it is envisioned that the closure bodies are spherical and / or comprise an elastic coating, in particular, elastic like rubber. This brings with it sealing properties of the sealing device particularly safe in the open state. If the coating has elastic properties it makes it possible for the respective closing body to grow and shrink, so it is particularly useful in combination with the use of materials with high thermal expansion coefficients as the main material of the closing body. As coating materials, for example, elastomers, in particular perfluoroelastomers, or silicones, can be used.
    In another advantageous development of the invention, it is envisioned that at least part of the empties of the sealing body are limited by at least one barrier element in order to prevent the closing body from leaving the emptying. This ensures safe operation thanks to the safe arrangement against body falls.

    of respective closure. The barrier element may be configured, for example, as a protuberance.
    In another advantageous development of the invention, it is proposed that the sealant body be at least partially configured as open-pore foam and / or that the sealants emptied are at least partially disposed as a reticle. This makes possible a simple adaptation of the sealing properties to different applications.
    The sealing device can be manufactured by a method in accordance with the first aspect of the invention, in which at least one sealing body is provided with several empties and at least one switching means, which is switchable between an open state and a closed state, where, at least in the open state, the empties of the sealing body allow a fluid to flow through them and, in the closed state, comprise a smaller cross-sectional area than in the open state through which can flow a fluid. The sealing device manufactured in this way can be switched between an "open" open state, in which a fluid can flow through the drains, and a "partially open" or "closed" closed state, in which, in comparison with the open state, less fluid can pass through time or at least essentially no fluid can pass through the drains, for example, given equal or at least comparable fluid flow conditions, thus, the sealing device according to the invention can to be switched between at least the first and the closed state, thus modifying the possible flow of said fluid.Therefore, the sealing device can be used, for example, in the context of a dishwasher machine.During the washing period, the sealing device It is switched to the closed state or "closed" state to ensure good thermal and acoustic insulation. During the drying phase of the dishwashing process, the sealing device can be switched to the open state or "open" state, thus allowing hot steam to flow through it and, therefore, the drying times are longer. Briefly, other applications are also conceived, for example, a porous gas burner that allows the flame to pass through the sealing device in the open state and which can be closed by switching the sealing device to the closed state in order to avoid leaks of gas or that the flame causes damage.The fluid may in general be a liquid, a suspension, a dispersion and / or a gas.
    In an advantageous embodiment of the invention, it is envisaged that at least the sealant body is manufactured by an additive manufacturing method, by means of a
    5
    10
    fifteen

    35
    injection molding method, by an injection foaming method, by a sintering method, or by a combination of these. This makes it possible for the sealing device to be manufactured depending on the materials selected and its future application. Additive manufacturing processes allow the manufacture of complex geometries with recesses, so that the sealing device can be adapted to different household items or appliances. However, for some applications, injection molding and / or injection foaming can be used to make the sealing device particularly quickly and economically.
    In another advantageous development of the invention, it is envisioned that the sealant body is manufactured at least partially from at least one material, which is selected from the group of plastics, metals, metal alloys, and ceramic materials. This makes possible an optimal adaptation to different specifications and requirements.
    In another advantageous development of the invention, it is envisioned that the sealant body is manufactured with recesses comprising passage openings, and at least one closure body is disposed in at least a part of the recesses so as not to cover the passage openings at least partially in the open state and to close the passage openings at least to a large extent in the closed state. Expressed in other words, it is anticipated that at least one of the emptyings or all the emptyings will be provided with one or more closing bodies that may not cover the respective passages, through which the fluid can enter and / or exit the emptying to pass through the sealing body in the open state, and close said openings at least to a large extent or completely in the closed state to prevent fluid from passing through the sealing body in the direction of a spherical valve. In general, the closure bodies can also be manufactured from at least one material, which is selected from the group of plastics, metals, metal alloys, and ceramic materials. In combination with an additive manufacturing process, the closing bodies can be placed in some or all of the empties of the sealing body during manufacturing, so that the sealing bodies can be easily secured by at least one barrier element subsequently manufactured inside of their respective emptyings. In the case of injection molding and / or injection foaming, the raw materials of the closing bodies can be injected together with the raw material of the sealing body or placed inside the material of the sealing body after injection / expansion of The raw material of the sealant body.

    The second aspect of the invention refers to a household item, in particular, to a household appliance, which comprises at least one sealing device, which is configured in accordance with the first aspect of the invention and / or is obtainable and / or is obtained by a method in accordance with the second aspect of the invention. The resulting features and their advantages can be drawn from the description of the first and second aspects of the invention.
    In an advantageous embodiment of the invention, it is envisaged that the household article is configured as a household water-conducting device, in particular, as a dishwasher or apparatus for treating clothes for washing and / or drying clothes, or as an apparatus for cooking for food.

    Figure 1 shows a perspective view of a sealing device 1 in accordance with a first embodiment, and will be described together with Figure 2, which shows a sectional top view of the sealing device 1. The sealing device 1 is configured to be used as a "multiple on / off valve" in a dishwashing machine and comprises a sealing body 2 which, in general, is rectangular, is open on one side, made of plastic, and comprises several emptyings 3 on a wall The recesses 3 are arranged as a reticle and are in fluid communication with the hollow interior of the sealing body 2 and, therefore, with the opening 4. A spherical closing body 5 is placed in each recess 3. Thus, each recess 3 or pore comprises a central section with an essentially spherical geometry, where the diameter of the spherical central section is greater than the diameter of the bodies of c ierre 5, so that the closing bodies 5 can move freely within the central section. The closing bodies 5 are composed of magnetic steel and can be moved inside the recesses 3 by a switching means 6 to switch the sealing device 1 between an open state or "open" state and a closed state or "closed" state. The
    5
    10
    fifteen
    twenty
    25
    30
    35
    empties 3 of the sealing body 2 allow a fluid to flow through them in the open state. In the closed state, the recesses 3 are blocked by the closing bodies 5, so that the area of the cross-section through which a fluid can flow is smaller than in the open state. Preferably, the inlet or outlet section of the recesses 3 is completely blocked by the closing bodies 5, so that, under the given conditions, no fluid or at least essentially no fluid can flow through it.
    The switching means 6 is configured to move the closing bodies 5 by generating a magnetic field near the surface of the sealing body 2. The closing bodies 5 are moved from the floor of the recesses 3 to the duct section of the emptied 3 to close the entrance or cross-sectional area, thus bringing the sealing device 1 from the open state to the closed state. If the magnetic field is deactivated, the closing bodies 5 fall into the central section and allow the passage of a fluid through the sealing device 1. It is obvious that the principle of operation of the switching means 6 can be reversed. Also, the switching means 6 can generally be located in different locations as required, and can be, for example, integrated in the sealing device 1. Therefore, the sealing device 1 can be switched between an open porosity state and a closed porosity state.
    Figure 3 shows a perspective view of the sealing device 1 according to a second embodiment. In comparison with the first embodiment, the sealing device 1 according to the second embodiment has a higher flow rate in the open state, since the geometry of the recesses 3 has been extended, while the diameter of the central sections is the same as in the first embodiment. In order to prevent the closing bodies 5 from falling out, the recesses 3 have been provided with two solid barrier elements 7 (protuberances). Another difference with respect to the first embodiment is that the left row of the recesses 3 arranged as a grid is devoid of closing bodies 5, so that it is always in the open state or "open" state. Optional embodiment ensures a certain minimum flow rate of the fluid regardless of the change status of the sealing device 1.
    Figure 4 shows an enlarged exterior view of a recess 3 that is limited by said barrier element 7, while Figure 5 shows an enlarged interior view of the recess 3 and the barrier element 7. It is clearly observed that the element of barrier 7 has a spherical interior shape to accommodate the closure body 5
    5
    10
    fifteen

    35
    respective spherical and close the fluid passage through the drain 3. However, different geometries of the drains 3 are conceived, depending on the subsequent application of the sealing device 1.
    Figure 6 shows an enlarged interior view of the recess 3 and a barrier element 7 formed alternately. In this case, the closing body 5 has to be attracted perpendicularly to the surface, so that a higher intensity magnetic field is needed compared to the previous examples.
    Figure 7 shows a perspective view of the sealing device 1 according to another embodiment, while Figure 8 shows a top perspective view of this sealing device 1. This embodiment makes it possible for the sealing device 1 to change from "porosity. open ”to“ closed porosity ”. The drains 3 are adjacent to each other and are interconnected in terms of fluids through small passages. If the magnetic field is deactivated, the spherical closing bodies 5 (not shown) meet on the floor or bottom surface of the recesses 3 and allow a fluid to pass through the sealing device 1. In this open state, the sealing device 1 has an "open porosity." If the magnetic field is lit through the switching means 6, the closing bodies 5 are forced to close the passages between the recesses 3, thus preventing the fluid from passing through the sealing device 1. In this closed state, the sealing device 1 has a "closed porosity". A suitable material for the closing bodies 5 is, for example, AISI 430 (ferritic), AISI 630 (precipitation hardening), AISI 316 L (austenitic), AISI 630, or 420 (martensitic) steel.
    In another embodiment, the closure bodies 5 are made of materials with a high thermal expansion coefficient. With this configuration, the lower temperatures cause the diameter of the closing bodies 5 to be reduced, so that a fluid can pass through the sealing device 1 then "porous." At higher temperatures, the closing bodies 5 will grow and reduce the flow or will completely close the recesses 3, so that the sealing device 1 has a kind of "closed porosity".
    In all embodiments, the closure bodies 5 may in general be magnetic particles. Likewise, the closing bodies 5 may be provided with a coating to guarantee optimum sealing in the closed state. If the coating has elastic and, in particular, rubber-like properties, the coating can easily adapt to changes in sizes due to temperature changes.

    Suitable materials for closing bodies 5 with high thermal expansion coefficients comprise AISI 316 L (austenitic) and AISI 630 (expansion coefficient at> 18 * 10-6K-1 at 20 ° C). In addition, polymeric materials such as EEA (expansion coefficient a = 288 * 10-6K-1 to 450 * 10-6K-1) or PB (a = 424 * 10-6K-1 could be used for closure bodies 5 to 432 * 10-6K-1).
    Figure 9 shows a schematic view of an aughetic sealant body 2 in a closed state, while Figure 10 shows a schematic view of the aughetic sealant body 2 in an open state. The main property of the aughetic materials is a negative Poisson coefficient. This means that the sealing body 2 thickens perpendicularly to the force I applied when it is stretched. Together with the sealing body 2, the drains 3 and their cross-sectional area are also increased, thus allowing the fluid to pass through the sealing device 1 with a higher flow rate. A comparison of the height of the sealing device 1 in the open state Xa and in the closed state Xb is illustrated in Figure 10.
    Using this behavior, the porosity and, therefore, the maximum fluid flow rate, can be modified by stretching or releasing the sealing device 1. The force I can be, for example, applied by means of displacement 6 comprising mechanical displacement components such as pistons, pinions and zippers, or the like. However, temperature changes can also be used to bring the sealing device 1 between the first and the closed state, so that the sealing device 1 can be easily integrated into household appliances, for example, in dishwashers, cavities of ovens, or the like. An appropriate aughetic material is, for example, "RP30048 Richfoam Polyether", from Carpenter.
    If an aughetic material is used to make the sealing body 2, it is possible to use closing bodies 5 additionally to modify the porosity. The closing bodies 5 can be made again of stainless steel (AISI 316 L, AISI 430, ...) to avoid corrosion problems. These materials are used in powder metallurgical technology, and are commercially available in a wide range of particle diameters.
    Figure 11 shows a perspective view of the sealing device 1 according to another embodiment, where the sealing device 1 has been brought to the open state to allow a fluid to pass through the sealing device 1. Figure 12 shows a perspective view of the device sealant 1 that has been brought to the closed state so that the fluid cannot pass through the sealing device 1. The sealing device 1
    5
    10
    fifteen

    25
    30
    It comprises a sealing body 2 made of a very porous material (more than 15 cells per 1 cm), such as foams or porous ceramics. The sealing body 2 comprises under the emptied 3 ferrite particles as closing bodies (not shown), which can be displaced through a magnetic field to carry the sealing device 1 between the open state of "open cells" and the closed state "of closed cells", in which the sealing body 2 has cavities or emptyings 3 closed. The magnetic field can be generated by corresponding displacement means (not shown).
    The sealing device 1 can be integrated, for example, in the tank of a dishwasher. Therefore, the dishwasher can be provided in such a way that it has insulating walls during the washing periods to avoid heat losses and conductive walls during the drying periods to reduce the drying time.
    However, other applications are conceived for the sealing device 1. By way of example, a gas burner may be equipped with the sealing device 1 to allow the flames to pass through the sealing device 1 in the open state and to seal the burner in The closed state. In general, any household item or household appliance that is associated in some way with smoke, steam, liquids, air, gas, or other fluids, may be equipped with the sealing device 1 in order to allow the fluid to flow through the sealing device 1 or blocking the passage of fluid. Therefore, the sealing device 1 can be designed, for example, as a cover or stopcock for household items or appliances for preparing food. The sealing device 1 may be formed, for example, as a cover or lid of a pan. By switching the sealing device 1 between the first and the closed state, the drains 3 or pores of the sealing body 2 can be opened or closed to allow steam or smoke to leave the pan or pot, or to maintain steam or smoke inside the pan or pot.
    In general, the sealing device 1 can be manufactured by additive manufacturing processes to allow the introduction of closing bodies 5 into the porous structure of the sealing body 2. This technology is ideal for sealing devices 1 with complex geometries.
    Alternatively, injection molding could be used to produce certain embodiments of the sealing device 1. The selection of appropriate raw materials such as powders, magnetic closure bodies, main material (steel, ceramic,
    plastic, and the like), and binder, if needed, depends on the shape and desired properties of the sealing device 1.
    If metallic or ceramic materials are used as main materials to manufacture the sealing body 2, the closing bodies 5 would generally withstand 5 elevated temperatures to allow sintering or molding of the main material without problems. Correspondingly, any optional binder composition should generally be selected so as to have low melting temperatures to allow for simple disengagement.
    Depending on the final application of the sealing device 1, injection foaming processes can also be used to manufacture at least the sealing body 2. A wide range of polymer foams and metal foams can be used for this purpose.
    The person skilled in the art will understand that, while the present invention has been disclosed herein with reference to the preferred embodiments, various modifications, changes, and additions to the invention set forth above may be made, without abandoning the spirit nor the scope of it. The parameter values used in the claims and in the description to define the process and measurement conditions for the characterization of specific properties of the invention are also included within the scope of deviations, for example, as a result of measurement errors. , of system errors, weight errors, DIN tolerances, and the like.
