Fireplace kit

The invention relates to a chimney kit with a chimney insert pipe and with an exhaust gas connection line between the boiler and the chimney insert pipe, at least one closable cleaning opening and, if necessary, a chimney head hujbe.

Such chimney sets are preferably used in existing brick chimneys in order to achieve a cross-sectional reduction adapted to newer boilers. The way newer boilers operate is such that the exhaust gas temperatures in the chimney are lower than before. If the exhaust gas temperatures are lower, the temperature may fall below the dew point, with the result that the flue gas condenses. The condensate flows down the inner wall of the chimney pipe. It is known to drain the condensate to the outside through a drain line attached to the base of the chimney.

The exhaust gas connection coming from the boiler flows into the chimney pipe. The problem at this point is that condensate coming from above on the inside of the chimney pipe can enter this exhaust gas connection and, in the worst case, into the boiler and destroy it.

Furthermore, at least one cleaning opening is provided that can be closed with a door and that opens into the chimney insert pipe at a different location depending on the local conditions. Here too, there is the problem that condensate is directed outwards in the area of this cleaning opening and, for example, escapes at the cleaning door.

If a chimney hood is provided, the reduction in flue gas temperatures, particularly in the area of the chimney hood, leads to poorer flow conditions, which can lead to turbulence directly inside the chimney hood. Such turbulence leads to a deterioration in the flow conditions in the chimney.

In order to remedy the disadvantages described, the invention is based on the task of proposing measures by means of which the adverse consequences of a temperature falling below the dew point can be reduced or kept as low as possible.

To achieve this object, the invention provides that mechanical control devices are provided to prevent or reduce the consequences of the temperature falling below the dew point.

In particular, it is provided that the mechanical guide device associated with the exhaust gas connection line has a bead for collecting and draining condensate, which runs essentially around the circumference and opens into the chimney pipe at its lowest point. The bead can be designed in such a way that the condensate is drained into the chimney insert pipe. In this case, the bead is preferably designed to run completely around the circumference and has a side opening in the lowest part for draining condensate into the chimney pipe.

Additionally or alternatively, it can be provided that the bead is designed to run completely around the circumference and has a drainage device for draining condensate to the outside at the lowest point in the operating position. This can preferably be provided near the boiler nozzle in order to prevent in any case condensate, which has entered the exhaust gas connection line in an undesirable way, from entering the boiler or other devices arranged between the bead and the boiler.

The mechanical guide device associated with the cleaning opening has a condensate deflector plate that can be inserted into the connection box that can be connected to the chimney pipe and closed with a door. This type of condensate deflector plate prevents condensate that arrives above the connection box from entering it and escaping via the door.

Preferably, the condensate drain plate

one in a lower sewing pr/f 1 &igr; of the AnSCn &igr; iiSk 55 teiiS cifi which can be placed and, in the position of use, rests against lateral stops under spring preload and a bridging plate intended for opening into the chimney pipe. In this way, the condensate discharge plate can be adjusted as easily as possible between the connection box, which is usually rectangular, and the generally round cross-section of the chimney insert pipe.

To generate the spring preload, a spring clip is preferably provided on the plate which, in the position of use with the door closed, rests against the inner side of the door under pressure.

In order to prevent the condensate drain plate from falling out when the door is opened, a further design provides for a retaining device for the condensate drain plate in the upper area of the connection box, designed as a locking device.

In a practical embodiment, it can also be provided that the lower receiving profile is arranged at a distance from the inner floor of the connection box. This ensures that condensation forming inside the connection box can reach the inside of the chimney insert pipe and is not prevented from doing so by the condensate discharge plate.

According to a further feature of the invention, it can be provided that the mechanical guide device associated with the chimney hood has a guide body arranged on the underside of the chimney hood and tapering towards the center of the chimney pipe. In the case of a chimney insert pipe with a round cross-section, it is particularly expedient to design the guide body as a straight circular cone.

The invention is explained in more detail below with reference to the exemplary embodiments shown schematically in the drawings. They show:

In Fig. 1, a section of a chimney insert pipe is designated with 1. An exhaust gas connecting line designated with 2 opens into the chimney insert pipe, which is provided for establishing a connection to a boiler (not shown). In order to collect and drain condensate which runs downwards inside the chimney insert pipe, a bead 3 running essentially over the circumference is provided in the vicinity of the connection point between the chimney insert pipe 1 and the exhaust gas connecting line 2. The bead 3 has a lateral opening 4 in its lower part, such that condensate which collects in the bead 3 can flow through the opening.

4 Inside the chimney insert pipe 1 1&eegr; is directed downwards in the direction of arrow A. In this way, condensate is prevented from flowing from the chimney insert pipe 1 through the exhaust gas connecting line 2 in the direction of the boiler (not shown).

In Fig. 2 and Fig. 3 there is a

A connection piece of a boiler (not shown) marked 5s or 5b is attached. For the collection and drainage of condensate, a circumferential bead 3a is provided as shown in Fig. 2 and a circumferential bead 3b is provided as shown in Fig. 3. The beads 3a and 3b have drainage openings 6 leading to the outside.

Fig. 4 shows a cleaning opening that is installed at a suitable location in the chimney and opens into an opening (not shown) of a chimney insert pipe (not shown in Fig. 4 or 6 to 8). The cleaning opening has a rectangular shape, for example.

9 and side frame parts 10 and 11. A pivoting door is designated 12 and is only shown in Fig. 4, but not in Fig. 6 to Fig. 8. The frames 8 to 11 are adjoined by an inner floor 13, which is inclined from the door 1 in the direction of the chimney insert pipe, and an upper part 14. On the inside of the upper part 14, a retaining device designed as a locking device 15 is provided for a condensate discharge plate 16, which can be inserted into U-shaped receiving profiles 17 of the connection box 7. The condensate discharge plate has a plate 18, to which a bridging plate 19 is attached, which is intended for opening into the chimney pipe (not shown). The bridging plate 19 1 is folded over at its front end and according to the

The respective curve of the chimney insert pipe is rounded. In the position of use, the plate 8 of the condensate discharge plate rests against the lateral stops of the connection box 7, of which only one lateral stop 20 is shown in Fig. 6 to Fig. 8. The inside 21 of the door 12 (not shown in Fig. 6 to Fig. 8) presses in the closed state on a spring clip 22 which is attached to the plate 18 on the flat side opposite the bridging plate 19.

Fig. 6 shows the position of the condensate discharge plate 16 in the position of use, in which the discharge plate is pressed against the side stops, e.g. 20, by the pressure exerted by the closed door 12 on the spring clip 22. The bridging plate 19 overlaps the opening of the carbine insert pipe, not shown in Fig. 6. This prevents condensate from penetrating the connection box and possibly escaping to the outside.

In Fig. 7 it is shown that the condensate discharge plate 16 can be taken out by grasping it in the spring clip 22 with the door open and pulling it forwards slightly at the bottom and then removing it by lifting it slightly.

Fig. 8 shows a position during the insertion of the condensate drain plate. This is first inserted into the receiving profile 17 or 18 at the bottom. By pivoting to the left as shown in Fig. 8, the spring-like retaining device 15 is overcome, which prevents the condensate drain plate from accidentally falling out when the door is open.

As can be seen from Fig. 6 to Fig. 8, the lower receiving profile 17, 18 is arranged at a distance from the inner base 13 of the connection box 7.
