Definitions

  • the invention relates to an electrical storage heater with a ceramic heat storage core.
  • the storage core consists of a material with high specific heat, preferably magnesia stones. Due to the high specific heat, the storage core is able to absorb a relatively large amount of heat.
  • the memory core is heated to a temperature level of around 800 ° C. Since the storage heaters are housed in living rooms, the storage cores must be heat-insulated and protected against accidental contact, because otherwise the stored heat would be released to the ambient air undesirably quickly and, on the other hand, every touch of the storage heater for the operator entails the risk of dangerous burns would.
  • the known electric storage heaters therefore all have an essentially closed protective housing, preferably composed of a plurality of metal sheets.
  • the memory core is arranged so that it cannot be touched in this protective housing.
  • An insulating layer which preferably consists of insulating plates, is also attached between the housing inner walls and the storage core.
  • the functionality of the electric storage heaters is as follows: The ceramic storage core is heated during the low-tariff night tariff period. The stored core slowly releases this stored heat into the ambient air to be heated up during the day. For this purpose, ambient air is sucked into the storage heater, passed over the storage core and expelled from the storage heater. The storage heater is therefore effective as a heat exchanger. To accelerate the heat exchange, a blower is also provided on the storage heater to accelerate the air flow to be heated.
  • Such an electric storage heater is known for example from DE-C-36 03 615.
  • thermal insulation mats have been used in the known storage heaters.
  • mineral fiber mats were used in places that allowed any wall thickness. These mineral fiber mats are inexpensive and, with the appropriate wall thickness, also have the required insulating properties.
  • soft heat insulation mats were used in the known storage heaters in areas with limited installation space. These soft thermal insulation mats have an extremely high insulating ability and can be designed with thin walls. From DE-A-2 611 115 a boiler is known which is thermally insulated by means of elastic insulating mats. However, the soft thermal insulation mats are high quality and accordingly expensive to buy.
  • DE-C-36 03 615 therefore proposes to manufacture at least the surfaces of an insulation block arranged below the storage core and facing the air flow from non-fibrous thermal insulation material.
  • Microporous silicon oxide is known as a fiber-free material for soft material thermal insulation boards.
  • the vermiculite insulation is also made, for example Römpp-Chemie-Lexikon, 9th edition, 1992, pp.4896f. ISBN 3-13-735109-X, Thieme Verlag, Stuttgart known. Vermiculite is also characterized by its good formability and dimensional stability DE-A-37 00 478 known.
  • a disadvantage of installation as insulating plates in a storage heater is that several hard insulating plates must be arranged horizontally and vertically to one another. Gaps often remain on the abutting surfaces of a vertically arranged and horizontally arranged hard insulating plate, that is to say in the region of the abutting edges of the insulating plates. These columns act as thermal bridges, so that heat escapes from the interior of the storage heater to the outside in an uncontrolled manner. So far, the sealing properties of such hard insulating plates have not been sufficient for electrical storage heating devices.
  • the invention is based on the problem of designing the hard insulating plates in such a way that their insulating effect also satisfies in the region of the abutting edges and such hard insulating plates are also suitable for use in storage heating devices. This object is achieved by the combination of features of claim 1.
  • the electric storage heater according to the invention also has the known heat storage core and the protective housing surrounding the storage core. Between the storage core and protective housing, the thermal insulation layer consisting of several fiber-free insulating plates is also attached.
  • the abutting edges of the insulating plates are designed as abutting surfaces according to the invention. As a result of this planar formation of the abutting edges, surface contact of the individual abutting surfaces occurs between two adjacent insulating plates in the final assembly state. This surface contact, which is to be dimensioned as large as possible, is effective in the manner of a surface seal. In this way, an absolutely heat-tight connection between the insulating plates is made.
  • the abutting surfaces of the insulating plates are developed in such a way that they are formed in the manner of a matrix and a patrix and, to a certain extent, interlock in the assembled state.
  • the abutting surfaces of the insulating plates according to claim 2 are consequently complementary to each other and interlock positively in the final assembly state. This form fit is effective in the manner of a labyrinth seal, so that the sealing effect in the joint areas is further improved.
  • a deformable sealing body is between the abutting surfaces of two adjacent insulating plates. Due to the surface pressure exerted by the abutting surfaces, this sealing body clings to the abutting surfaces and thus seals fine pores and uneven surfaces.
  • Suitable sealants are, for example, plastically deformable soft material plates (claim 4). The soft material adapts to the shape of the respective abutting surface when the neighboring insulating plates are braced against each other and thus provides a particularly good gap seal.
  • Also suitable as a sealant is elastically deformable, inorganic fiber fabric, quartz silk fabric or high-melting glass silk fabric is preferably used.
  • This fiber fabric is an elastic sealant and expediently has a fiber thickness of more than 5 ⁇ m.
  • This inorganic fiber fabric according to claim 5 is further developed according to claim 6 in that it is in the form of a fabric tube. These fabric hoses are placed in the butt joints of two adjacent insulating plates and laid flat, so that a slightly resilient insulating layer is created, which additionally increases the sealing effect, in particular the gap seal.
  • Vermiculite and microporous silicon oxide are particularly suitable for this.
  • Most of the side thermal insulation boards are hard insulating boards made of inorganically bound vermiculite and the vertical, upper and lower thermal insulation boards are high-density soft-body boards made of microporous silicon oxide.
  • other arrangements, combinations and materials are also conceivable both for the hard insulating boards and for the high-insulation soft-body boards and expressly form part of this invention.
  • water glass i.e. alkali silicate
  • the plates made of microporous silicon oxide can be produced by pressing and then sintering suitable starting materials.
  • Claim 10 relates to an advantageous pair of seals between a hard insulating plate and a high-insulation soft body plate.
  • the abutting surface of the hard insulating plate slightly compresses the abutting surface of the high-insulation soft-body panel, as a result of which the abutting surface of the hard insulating plate acts as a sealing edge.
  • Claims 11 to 13 relate to thermal insulation boards with cavities. These thermal insulation boards make it possible to accommodate fibrous, well-insulating materials in the cavities. Furthermore, the cavities are also suitable for holding any highly insulating insulating materials. In particular, the design according to claims 12 and 13 allows easy filling of the cavities with the insulating material.
  • the insulating plates are designed in two parts, one insulating plate part forming a bowl-shaped hollow shell, while the other insulating plate part forms a cover-like covering shell.
  • the cover shell can be placed on the hollow shell like a pot lid on a pot. When the cover shell is attached, the cavity is completely hermetically sealed off from the surroundings.
  • claim 13 proposes to incorporate several separate cavities into the insulating plate.
  • such separate cavities can also be filled with different insulating materials. This is useful if parts of the insulating plate have to be particularly well insulated, while other parts have less insulation. The insulation can thus be variably adapted to the respective requirements.
  • Claims 14 and 15 relate to through openings for lines.
  • Such lines can, for example, for the introduction of radiator rods, temperature sensors or the like. serve.
  • the inner surfaces of the passage openings are made of fiber-free material analogous to the bowl edges forming the outer walls of the cavities.
  • the insulating plates are therefore completely fiber-free not only with respect to their outer sides but also with respect to the inner sides of the passage openings and are therefore reliable.
  • the cross-sections of the through openings which are not filled by the lines are sealed with flange-like sealing plates.
  • the sealing plates are expediently welded to the insulating plates in the final assembly state. It is also possible to provide the sealing plates with counter brackets in such a way that the flange-like sealing plates lie flat on all sides on the insulating material walls, so that no undesired thermal bridges occur at these points.
  • the electric storage heater essentially consists of the protective housing, the heat storage core and the thermal insulation layer arranged between them.
  • the protective housing is formed from the side parts 1, 1 ', the housing rear wall 2, the housing base 3, the housing cover 4 and the housing front wall, not shown in FIG. 1.

  • the spacer 7 is also arranged between the high-insulation soft-body panel 6 and the housing base 3, the spacer 7 being designed as an air outlet grill in the region of the front wall, which is not shown in FIG.
  • the protective housing 8 assembled in FIG. 2 again has, according to FIG. 2, the housing rear wall 2, the housing cover 4, the housing base 3 and the housing front wall 9, not shown in FIG. 1.
