Description

The invention relates to a tiled stove.

Tile stoves are known in and of themselves in a wide variety of shapes and sizes. They are known to be composed of refractory bricks and slabs which are used to form both the firebox and the flue gas passageway. The refractory bricks and slabs are connected to one another by means of refractory mortars and connecting cross pieces, connecting tension elements or connecting brackets in such a way that they ultimately form a one-piece inner furnace core or furnace construction, the latter being exposed to greater thermal expansions. The inner furnace construction is then provided with an outer ceramic cladding or the like. Tile cladding which is connected to the inner furnace construction by means of refractory mortar or the like. The joints between the individual tiles are then sealed with mortar.

• - Das Kachelofenaufbauen ist zur Zeit praktisch lediglich von Ofensetzern bzw. Hafnern; d. h. von geschultem Personal durchfuehrbar.
• - Das Aufbauen eines Kachelofens verlangt einen erheblichen Zeitaufwand.
• - Wird der Kachelofen in einer bewohnten Wohnung aufgebaut, so wird der Wohnraum, wo der Kachelofen aufgebaut wird, in eine Baustelle verwandelt.
• - Die jeweils gewuenschten Kachelofengroessen bzw. -gestaltungen verlangen meistens eine lediglich durch Bearbeitung auf Mass zu. erhaltende Anpassung der eingesetzten feuerfesten Ziegel oder Platten. Mit den ueblichen feuerfesten Ziegeln bzw. Platten ist es ferner nicht immer moeglich, die Querschnitte der Rauchgaszuege an die theoretische bzw. gewuenschte Rauchgasgeschwindigkeit anzupassen, und beim Versuchen, diesen Erfordernissen zu genuegen, wird es meistens schwer sein, die Dicken der eingesetzten feuerfesten Ziegel und Platten derart zu bemessen, dass eine wirksame Waermeentnahme aus den durchstroemenden Rauchgasen gewaehrleistet wird, so dass der gewuenschte thermische Wirkungsgrad beeintraechtigt wird.
• - Der innere monolithische Ofenbau ist staerkeren Waermebeanspruchungen ausgesetzt, die zu Rissen des inneren Ofenbaus fuehren koennen, wobei diese Risse sich in der aeusseren Kachelverkleidung fortpflanzen koennen und insbesondere bei emaillierten Kacheln nicht mehr zu verheimlichen sind.

The usual design of the well-known tiled stoves has several disadvantages and inadequacies in practice:

• - The tiled stove construction is currently practically only by stove setters or ovens; ie can be carried out by trained personnel.
• - Building a tiled stove requires a considerable amount of time.
• - If the tiled stove is set up in an inhabited apartment, the living room where the tiled stove is set up is converted into a construction site.
• - The desired tiled stove sizes or designs usually only require one by machining to measure. preserving adaptation of the refractory bricks or slabs used. Furthermore, with the usual refractory bricks or slabs, it is not always possible to adapt the cross sections of the flue gas trains to the theoretical or desired flue gas speed, and when trying to meet these requirements, it will usually be difficult to determine the thicknesses of the refractory bricks and To dimension plates in such a way that an effective heat removal from the flowing smoke gases is guaranteed, so that the desired thermal efficiency is impaired.
• - The inner monolithic stove construction is exposed to severe heat stresses, which can lead to cracks in the inner stove construction, whereby these cracks can propagate in the outer tile cladding and are no longer to be concealed, especially with enamelled tiles.

• - die Herstellung derselben erfolgt mit Pressformen, so dass dieselbe langwierig und kostspielig ist ;
• - die Kacheln weisen ein festes Format auf, so dass auch die Kachelofenabmessungen praktisch ebenfalls vorbestimmt sind ;
• - mit den dargestellten Kachelausfuehrungen ist es nicht moeglich, innere Kanaele zur Erwaermung der Luft zu gestalten.

DE-C-211 584 describes a tiled stove having a combustion chamber, a flue gas flue and an outer tile cladding, the flue gas path forming a self-supporting inner flue gas flue structure and consisting of a number of modular flue gas flue modules having several flue gas deflection openings, which are arranged with respect to one another in such a way that they are the same form a snake-like flue gas duct. The tiles proposed for the production of this tiled stove have the following main disadvantages: _t

• - The same is made with molds, so that it is tedious and expensive;
• - The tiles have a fixed format, so that the tiled stove dimensions are also practically predetermined;
• - With the tile designs shown, it is not possible to design inner channels for heating the air.

DE-C-675 269 discloses a shaped block for the production of ceramic ovens from horizontal layers, the proposed shaped block consisting of two perpendicular walls adjoining one another at right angles and a train dividing wall which extends horizontally or obliquely from the walls, so that a layer of each of two shaped stones joined together Oven is formed and smoke ducts rise in zigzag shape due to the overlapping draft doors. However, these shaped stones require difficult production. Furthermore, these shaped stones also have a fixed format. In addition, it is disadvantageous in the case of these shaped blocks that, as can be seen from FIG. 2, the cross sections of the flue gas draft path deviate greatly from one another over the course thereof.

It can be seen from GB-A-133850 that it is already known to arrange pipes for water and air heating in the flue gas passage of an oven. From the description and drawing it can be seen that a pipe coil is used, the individual snake dreams of which each rest on a horizontal partition wall forming the snake-like flue gas passage. This solution is therefore only possible if the interior of the flue gas duct is freely accessible from a large front wall. However, there is no indication as to how the pipe coil or the sets of pipe coils can be arranged in flue gas duct modules which are closed around themselves.

The invention has for its object to provide a tiled stove which is capable of making it easy and quick to build tiled stove and at the same time to eliminate the above-mentioned disadvantages and inaccessibility of the known tiled stove.

Starting from a tiled stove, having a combustion chamber, a flue gas flue and an outer tile cladding, the flue gas flue having a self-supporting interior Flue gas flue construction forms and consists of a number of modular flue gas flue gas components having flue gas deflection openings, which are arranged to each other in such a way that they form a serpentine flue gas flue path, the above-mentioned object is achieved according to the invention in that tubular, modular type inserts are inserted into the flue gas flue units or in the self-supporting internal furnace construction for the heating of air and water, it can be inserted that the internal flue gas duct is formed by a flue gas double column, the individual flue gas duct columns of which consist of a plurality of stack-like flue gas flue modules of two types, that the flue gas flue modules of both types have a hollow, essentially rectangular cross-section and Elongated building blocks with open end faces are executed, and in a side wall near a building block end face, a first flue gas deflection opening and in one horizontal block side, near the other end of the block, have a second flue gas deflection opening, with the one flue gas draft block type the second flue gas deflection opening in the one horizontal block side, while with the other flue gas draft block type the second flue gas flow deflection opening is provided in the other, and the one flue gas draft block is the horizontal block The flue gas column is rotated 180 ° around its longitudinal axis and is arranged in relation to the flue gas modules of the other layered flue gas column, so that the vertical flue gas deflection openings of two flue gas modules of the same type, which form a layer of the double flue column, face each other.

In the case of a tiled stove, which has a combustion chamber, a flue gas flue and an outer tile cladding, the flue gas path forming a self-supporting inner flue gas flue structure and consisting of a number of modular flue gas flue modules which are arranged with respect to one another in such a way that they form a snake-type flue gas flue path, the above-mentioned task According to the invention, this is achieved by inserting tubular modular insert-like inserts for heating air and water into the flue gas flue modules or in the self-supporting inner furnace construction, that the inner flue gas duct construction consists of a number of modular flue gas flue units of the same type that are rotated about their longitudinal axis , which are designed as hollow, generally rectangular cross-section and open end faces having elongated building blocks and in a horizontal building block side near one end of the building block have a first flue gas deflection opening and a second flue gas deflection opening in the other horizontal end face of the block near the other end face of the block.

With the solution according to the invention, it is possible to carry out the internal flue gas flue construction and the combustion chamber in a simple and rapid manner and without special specialist knowledge or manual dexterity, the outer furnace cladding consisting of tiles being subsequently detachably attached. The tile cladding can optionally consist of a conventional bricked-up, but preferably consists of a cladding composed of mutually known with detachable connecting strips or the like.

The modular principle laid down for the hollow flue gas flue modules and for the cladding tiles enables the cross-section of the flue gas flue modules and the wall thickness of the latter to be dimensioned correctly from the outset, so that on the one hand it is possible without further ado, a flue gas flue that approximates the optimal flue gas flue and on the other hand very high thermal To achieve efficiencies.

The provision of modular flue gas flue blocks allows the internal flue gas flue path, which is more appropriate from case to case, taking into account both the available space and other special requirements, e.g. B. the warming from convection of warm air for heating purposes.

In the provision of a predetermined or modular-type flue gas draft path, it is also ensured that the heat inherent in the flue gases is advantageously used effectively for heating warm air or hot water by inserting inner tubular heat exchanger inserts.

Yet another advantage of the solution proposed by the invention can be seen in the fact that the modular flue gas flue modules are produced in a design that can be easily arranged one above the other, so that stable and self-supporting flue gas flue columns can be produced quickly, the attachment of an outer tile cladding being made considerably easier.

The tile cladding thus forms an advantageously detachable sheath that is not or less threatened by the internal thermal expansion.

In one embodiment of the modular flue gas draft modules, it is also possible to produce tile stoves with small dimensions with a perfect flue gas draft and high thermal efficiency.

The invention will now be explained in more detail with reference to the schematic figures of the accompanying drawings, which are shown in different scales, but without being limited to the same.

The same tiled stove parts are provided with the same reference symbols in the different drawing figures.

The structure of a tiled stove according to the invention can be seen particularly from FIG. 2, the tiled stove being designated 1 in its entirety. Essentially, the tiled stove 1 contains a combustion chamber 2, an inner flue gas duct 3, and an outer tile cladding 4. The combustion chamber 2 consists of the refractory base plate 5, the side plates 6, the rear plate 7, the front plates 8 forming the loading opening 8a, and the Cover plate 9, in which the flue gas outlet openings 9a are provided.

The combustion chamber 2 is directly on the respective installation space, z. B. the floor concrete ceiling or the floor tiles or a prepared support base and serves as a support surface for the flue gas duct construction 3 lying thereon.

According to the invention, the latter consists of a number of modular flue gas drafting blocks 10 and 11 as shown in FIGS. 3 and 4.

These flue gas flue components 10 and 11 consist of a hollow, refractory, modular type component, which has a rectangular cross section in the example shown. The flue gas flue modules 10 and 11 each have two flue gas deflection openings 12 and 13, the first in a vertical side of the block and the second in a horizontal side of the block, namely in block 10 in the lower and in block 11 in the upper horizontal side of the block. 3, 3a and 4, 4a it can also be seen that the end faces of the module are free or open. This gives the advantageous possibility of a simple and cheaper production of the flue gas blocks in the extrusion process with subsequent separation cutting process.

If one now places a block 10 and another block 10 rotated about its longitudinal axis by 180 °, as shown in FIG. 5, the bottom flue gas layer 14 is obtained, the bottom block opening 12 being congruent over the flue gas outlet opening 9a of the combustion chamber cover plate 9. If one now places a building block 11 and another building block 11 rotated about its longitudinal axis by 180 ° over the flue gas draft layer 14, as shown in FIG. 5, the second last flue gas draft layer 15 is obtained to the following blueprint, add another flue gas layer 14, etc.

In order to produce the flue gas flue construction 3 shown in FIG. 2, it is only necessary to use shorter and possibly narrower flue gas flue components 10a and 11a for the reset tiled stove upper part 16.

With 10a refractory cover plates are referred to, which serve to close the open end faces of the modular blocks 10 and 11.

According to the invention, modular cladding tiles 17 are also proposed conditions, the height of which is equal to the height of the flue gas block 10 and 11 or an integer fraction thereof.

In FIG. 2, 18 vertical or horizontal connecting strips are also designated, which are received in corresponding receiving grooves 19 of the cladding tiles 17 or the further furnace cladding parts and connect them to one another.

The flue gas flue path is denoted by 20 in FIG. 5 and indicated by the dashed line and arrows.

2, 5, 7 to 10, 14, 15 and 19 to 22, the flue gas draft path is formed by a double column 27 consisting of the two flue gas draft columns 27a and 27b of flue gas draft modules 10 and 11 or 10a and 11a, the double column 27 consisting of there is a number of superposed flue gas layers 14, 15 and wherein in each flue gas layer 14, 15 the flue gases are deflected horizontally and vertically from a flue gas layer to the flue gas layer thereon.

7 and 9 show two exemplary embodiments of tile stoves provided for the production of warm air. With 21 and 22, between the outer tile cladding 4 and the inner flue gas duct 3, intermediate spaces or chambers are designated, the air entering the intermediate spaces 21 and 22 below and flowing upward after convection heating and flowing through upper openings into the living space emerges again. This warm air flow is indicated by arrows, the openings provided in the tile cladding being known per se and not shown in detail.

In FIG. 9, the intermediate spaces 21 and 22 end at the top in ventilation mouthpieces 23. The pipes, also designated with 24, for distributing the warm air in further living spaces could also be connected to the latter.

Both in the exemplary embodiments of FIGS. 7 and 9 and in the example of FIG. 8, modular flue gas draft modules of FIGS. 3, 3a and 4, 4a are used.

In FIG. 8, the intermediate space 25 intended for heating warm air is provided in the center. With 26 preferably made of stainless steel steel sheets are referred to, which are inserted between the individual flue gas layers 14 and 15, and have a width which is somewhat larger than the flue gas deflection opening 12 ending in the space 25. In the area of the inner edge of the flue gas deflecting opening 13, refractory separating elements (not shown) are arranged on the respective steel sheet 26 between the two building block columns 27a and 27b, which with the associated steel sheet 26 have the task of producing the necessary continuity between two opposite flue gas building blocks. Each steel sheet 26 with an associated separating element could of course consist of a single sheet metal part bent at right angles. Inner spaces are advantageously more efficient than lateral spaces.

7 and 8 there is also a through-opening 28 which opens into the dome 29 in order to heat the latter more intensely.

Reference is now made to FIGS. 11 and 12, which represent a preferred embodiment of a flue gas duct module 30 according to the invention in the two use positions. With this flue gas draft module 30 it is possible to build tile stoves with a single flue gas draft column 27, in which the flue gas draft path has a vertical, spiral-like course. This flue gas draft module 30 is also suitable for enabling the production of small tiled stoves.

11 and 12 can be clearly seen that in the lower and upper horizontal block surface in the position of use, a flue gas deflection opening 31 is provided on each end face. The end faces of this flue gas draft module 30 are also open. When forming a tubular gas train column 27 consisting of the building blocks 30, a building block 30 is first placed on the combustion chamber 2, after which a further building block 30 is rotated by 180 ° about its longitudinal axis. 16 tiled stove contains two superimposed modular building blocks 30. In the exemplary embodiment of FIGS. 14 and 15, two flue gas duct columns 27 consisting of building blocks 30 are provided, with 21 again denoting a space for warm air heating.

Halved building blocks 30, designated 30a, are used in the reset tiled stove upper part. By inserting an intermediate ring 32 between two half-components 30a, it is possible to achieve longer modular flue gas flue component lengths, the recessed upper part of the furnace being formed without the use of the intermediate ring 32.

With the module 30 shown, it is also possible to design a helical course of the flue gas draft path as shown schematically in FIGS. 17 and 18.

This solution, which is particularly intended for larger tiled stoves, allows more effective warming of warm air to be achieved. For the sake of clarity, FIG. 17 shows the uppermost flue gas block 30 before it was attached. In FIG. 18, 33 is also used to indicate a refractory support that has the same height as the building blocks 30.

In the embodiments shown in FIGS. 19, 20, 21 and 22, tubular inserts 34 according to the invention, which serve as heat exchangers for heating water, are provided.

For heating domestic hot water U-shaped ribbed pipe sections according to the invention, for. B. arranged in each flue gas layer, namely a U-leg in each flue gas brick 10 or 11, the free ends of the U-shaped pipe sections protrude from the tile cladding and the U-shaped inserts are connected in series.

35 designates a boiler-like pipe system formed from welded pipes, which is arranged in the combustion chamber 2 and serves to heat heating water for heating purposes. The input end 35a and output end 35b of the pipe system 35 are switched on in the radiator network.

In the intermediate space 21, a hot water tank 36 is designated in FIG. 22. In order to ensure warmer warm air, it is proposed according to the invention to arrange tubular inserts 37 in the intermediate space 21 or 22 or in the flue gas drafting blocks 10, 11 or 27 and, if appropriate, in the combustion chamber 2, the inserts 37 having lower ends 37a, which are close to the Floor, and have upper free ends 37b. By inserting the inserts 34 and 37, the cross section of the flue gas flue modules is in reality only slightly reduced, so that the flue gas flue is practically unaffected. With the proposed modular flue gas flue modules, it is therefore possible to sell all the modular flue gas flue modules, combustion chamber panels, cover plates, cladding tiles, superstructure parts, heat exchanger inserts, etc. required for the manufacture of a pre-planned tiled stove as a self-assembly kit, whereby the practical production of the tiled stove requires no special technical knowledge can be carried out.

The proposed modular tiled stove modules make it possible to produce practically any tiled stove shape and flawlessly drawing flue gas ducts simply, safely and with a considerably reduced expenditure of time.
