Description

The invention relates to a chimney with a fireplace arranged in the lower part of the chimney. The invention is based on a chimney with the features of the preamble of main claim 1.

the DE 10 2008 043 263 B4 describes such a chimney in which the fireplace is in the chimney base, ie arranged in the lower part of the chimney. The chimney base of this chimney is formed by a body which has a vertically extending cavity inside, in whose lower part the fireplace is accommodated and whose upper part is designed as a free space through which the exhaust pipe of the fireplace is passed. The cavity is covered at the top by an adapter plate placed on the body, through which the exhaust pipe extends. The adapter plate is connected to the body using fasteners. Above the adapter plate is the upper part of the chimney with a flue gas outlet pipe. The fireplace is designed as a convection fireplace. The cavity in which the fireplace is arranged forms a convection space for the convection air flow flowing through the cavity.

the DE 10 2017 112 874 A1 describes a similar to in DE 10 2008 043 263 B4 constructed chimney.

the EP 1 437 550 B1 also describes a chimney with a body forming the chimney base, which has a vertical cavity in whose lower part the fireplace is arranged and whose upper part is penetrated by the exhaust pipe. An essential difference from the known prior art mentioned above is that no adapter plate is placed on the body, which is connected to the body via fastening elements. The corpus of EP 1 437 550 B1 has an upper portion formed as a vertically extending solid wall. This massive wall extends approximately over a quarter of the vertical extent of the body. The massive vertical wall is penetrated by the exhaust pipe and a supply air pipe. The body with its bottom, side walls and top wall is designed as a one-piece body. On top of the vertical top wall, the top chimney is placed. The vertical top wall of the body forms a massive partition wall of the chimney.

The following prior art is also known:
the DE 195 11 586 A1 describes a chimney made of floor-to-ceiling chimney elements. The chimney elements each consist of an outer shell made of lightweight concrete with an inner pipe inserted therein with surrounding insulating inserts. The insulating inserts are floor-to-ceiling one-piece molded parts, each with a ventilation duct. The chimney elements are connected to anchor bolts via fasteners. The lightweight concrete outer shells are each tubular and open at the top and bottom. They do not form a body with a head end extending over the interior.

the DE 10 2015 111 294 A1 describes a modular chimney. The modules consist of mantle stones, each with a continuous cavity and a pipe arranged at a different height in it. During assembly, the tube can be displaced in the through-going cavity of the mantle block and can be locked therein via a stop device. The modules are connected using a fastening device with screw eyelets. The modules have complementary interlocking elevations and depressions on their abutting surfaces, which are formed at the ends of the mantle blocks by the pipes used at different heights. The fireplace is arranged in the floor module. The structural design of the floor module is in the DE 10 2015 111 294 A1 not described.

the DE 296 18 107 U1 describes a domestic chimney with prefabricated chimney components that are connected to one another via tie rods. The prefabricated chimney components each consist of a mantle block with a continuous cavity with a flue pipe arranged in it. The smoke tubes are each designed as socket tubes and are each held by a separate support ring on the top of the associated mantle stone. A chimney base with a fireplace arranged in it is in the DE 296 18 107 U1 not described.

At the in figure 1 illustrated first embodiment is a chimney S with a fireplace 1x, which is designed as a storage fireplace. The 1x fireplace is integrated in the base of the S chimney.

The chimney S has an outer shell made of concrete. The structure and the precise configuration of the outer jacket are described in more detail below. Chimney S is divided into three axial sections, hereinafter referred to as chimney levels 1, 2 and 3.

The lower first chimney level 1 contains the fireplace 1x.

The second chimney stage 2 is arranged directly above the first chimney stage 1. It contains an exhaust gas cleaning device 20. The exhaust gas cleaning system 20 is arranged in the exhaust pipe 4.2, which is connected to the fireplace 1x at the top and, as an exhaust pipe 4.2, penetrates the second chimney stage vertically. The exhaust gas cleaning device 20 is designed as a module and forms a structural unit with the exhaust gas pipe 4.2 of the second chimney stage. This structural unit consisting of the exhaust gas pipe 4.2 and the exhaust gas purification device 20 can already be installed in the second chimney stage 2 at the factory. However, it can also be retrofitted on site. This applies to the assembly of exhaust pipe 4.2 and exhaust gas cleaning device 20, but also for the exhaust gas cleaning device 20. This can also be installed alone on site as an optional retrofit or replaced as part of a repair or renewal on site.

The exhaust pipe 4.2 has a lateral socket with an inspection opening 4.2ö. The inspection opening 4.2ö is closed with a removable cover 4.2öv. The exhaust gas cleaning device 20 is accessible via the inspection opening 4.2ö.

In the illustrated embodiment in figure 1 the first chimney stage 1 and the second chimney stage 2 are designed as a structural unit with a common body 100 . The body 100 is a hollow body, which can be formed from concrete bricks, preferably mantle blocks, or as a one-piece concrete body. In the embodiment in figure 1 the interior of the body 100 is separated by a horizontal partition 100z. The partition wall 100z separates the first chimney stage 1 from the second chimney stage 2. In The lower part, ie below the intermediate wall 100z, is arranged in the fireplace 1x, in such a way that the intermediate wall 100z resting on the upper end of the housing of the storage fireplace 1x forms the head of the fireplace 1x. The intermediate wall 100z is directly connected to the body 100. In the embodiment in FIG figure 1 For example, the intermediate wall 100z is formed as a separate horizontal plate which is axially supported on a collar formed on the inner wall of the body 100.

In modified versions, it is possible that the horizontal partition 100z only rests on the fireplace, i.e. on the top of the fireplace and is only supported there, or that the horizontal partition 100z is only supported on the body 100, e.g. on a collar of the inner wall of the Body or engaging in the inner wall.

The exhaust gas pipe 4.2 of the second chimney stage passes through a connection opening in the intermediate wall 100z and engages in a head-side connection piece of the fireplace 1x, which is not shown. The flue gas pipe 4.2 of the second chimney stage, which contains the flue gas cleaning system 20, reaches with its upper end an opening in the head of the body 100 for connection to a flue gas pipe 4.3, which in the upper part of the chimney of the third chimney stage the flue gas vertically upwards through the upper part of the chimney to the outside. The exhaust line 4.3 is designed as an exhaust pipe and engages in a connection socket 4.3a supported on the head of the body 100. This connection socket 4.3a is designed as a load-bearing connection socket, which supports the inserted exhaust gas pipe 4.3.

The upper part of the chimney S is formed by the third chimney stage 3 . This contains the exhaust pipe 4.3, which is connected to the exhaust pipe 4.2 of the second chimney stage via the connection socket 4.3a in order to lead the exhaust gas through the third chimney stage and finally to the outside at the chimney top.

The third chimney stage 3 can be composed of floor-to-ceiling chimney sections. The floor-to-ceiling chimney sections can be designed as prefabricated parts that are assembled on site at the construction site. Alternatively, the third chimney stage 3 can also be designed over its entire height as a factory finished part. The outer shell of the third chimney stage is like the outer shell of the first and the second chimney stage made of concrete material, preferably of mantle stones. However, it can also be formed from one-piece pipe sections, preferably storey-high pipe sections, or alternatively, depending on the height of the chimney, from a one-piece pipe section.

In the two lower stages, ie in the first chimney stage and in the second chimney stage, in the embodiment in figure 1 in the outer casing, ie in the common body 100, two inspection openings 100ö, 100ö are formed on the side. The inspection opening 100ö in the first chimney stage forms an access opening to the furnace door 1xv of the storage fireplace 1x. The inspection opening 100ö in the second chimney stage 2 has a closure, e.g. B. a door 100öv, and forms an access to the trained in the exhaust pipe 4.2 inspection opening 4.2ö or its closure flap 4.2öv. About the inspection opening 4.2ö is the exhaust gas cleaning device 20, which is inside of the exhaust pipe 4.2 is arranged, possible. In addition, a mechanical soot removal device is also accessible via this inspection opening 100ö in the second chimney section, which in the embodiment in figure 1 is formed by a ball stop device 2k with locking slide 2s. The locking slide 2s forms a soot trap when turning. The bullet arrester 2k provides mechanical protection for the fireplace when turning.

Both in the third chimney stage 3 and in the second chimney stage 2, vertical air supply lines (not shown) are arranged, which supply the air supply to the fireplace in countercurrent to the exhaust gas line 4.3 and 4.2.

At the in figure 2 The second exemplary embodiment illustrated is a chimney S which, in contrast to the first exemplary embodiment, has a convection fireplace 1x with a convection chamber as a fireplace 1x. The rest of the structure of the chimney is the same as in the first exemplary embodiment; in particular, the exhaust gas pipe 4.2 of the second chimney stage with the exhaust gas cleaning device 20 integrated therein is of the same design. Also in the second embodiment in figure 2 the body 100 with the first chimney level 1 and the second chimney level 2 forms a prefabricated part ex works. In the second exemplary embodiment, the finished component 120 is figure 2 designed differently than in the first embodiment in FIG figure 1 . The differences are explained in detail below. The third chimney stage 3 is identical in the first and second embodiment.

The following describes the differences in the prefabricated element that forms the first and second chimney stage, i. H. the differences of this prefabricated component forming the chimney base in the second embodiment compared to the first embodiment.

In the second embodiment in figure 2 the body 100 has a cavity 100h, which forms a common cavity as a receiving space for the fireplace 1x and the exhaust gas pipe 4.2 with the exhaust gas purification device 20 arranged therein. In contrast to the first exemplary embodiment, in the second exemplary embodiment there is no intermediate wall 100z which divides the cavity 100h into two separate receiving spaces, namely a lower receiving space and an upper receiving space. Such a subdivision is in the first embodiment figure 1 the case where there is a lower accommodation space in the body 100 for accommodating the fireplace 1x and, separated by the partition 100z, an upper accommodation space for accommodating the exhaust gas pipe 4.2 with the exhaust gas cleaning device 20 integrated therein Cavity 100h formed for the first and second chimney stage. A convection air flow K is guided in this common cavity 100h, which is formed by an air flow that flows in at the lower inspection opening 100ö, is heated when passing the outer wall of the fireplace 1x on the outside of the exhaust pipe 4.2 and finally flows out at the upper inspection opening 100ö. In each of the inspection openings 100ö, 100ö, an inspection grille 100kg is used.

In the second embodiment in figure 2 the heat exchange of the chimney with the environment takes place via the convection air flow, which is generated as a warm air flow when flowing through the first and second chimney stage on the outer wall of the fireplace 1x and on the outside of the exhaust pipe 4.2 and which, after escaping through the convection openings, heats the environment . In contrast, in the first embodiment, in which the fireplace 1x is designed as a storage fireplace, the heat generated in the fireplace is stored primarily in the fireplace storage and possibly also in other storage areas of the chimney, e.g. in the chimney wall. The heat is then transferred to the environment via heat radiation from the body 100 to the environment.

Modified exemplary embodiments, which have a mixed form of the fireplace 1x as a storage fireplace and at the same time as a convection fireplace, are also provided. These have the same as the embodiment in figure 1 a storage fireplace, but in contrast to the embodiment in figure 1 they also have a convection chamber formed in the body 100, which enables a convection air flow K through the interior of the first chimney stage 1 and the second chimney stage 2. In this embodiment, the body 100 is similar to the embodiment in FIG figure 2 Convection openings 100ö provided, namely also a convection opening 100ö the first chimney stage and a convection opening 100ö in the second chimney stage. In order to enable the vertical convection flow K inside the first and second chimney stage, corresponding passage openings are formed in the intermediate wall 100z in these exemplary embodiments. At the in the Figures 3a and 3b The exemplary embodiment shown is, as in exemplary embodiments 1 and 2, a three-stage chimney with a fireplace 1x arranged in the first stage.
