Description

The Innovation relates to a silencer, in particular for a room air independent operated heater, after the preamble of the protection claim 1.

Generic mufflers are particularly known as separate built-in parts for flue gas exhaust pipes or exhaust pipes of boilers, which are fired with oil or Gasgebläsebrennern. Due to the combustion air blower disturbing noises in a building can result in connection with the installation and / or operating conditions, which are reduced by a silencer. These known, axially flowed through mufflers usually have an outer tube with an inner Schalldämmpackung, which consists for example of stainless steel wool and is disposed between the outer tube and an inner flow channel for the exhaust gas in the longitudinal direction. The inner boundary of the Schalldämmpackung or the flow channel forms a perforated inner tube. Exemplary embodiments of such mufflers contain the DE 90 05 421 U1 as well as the DE 298 24 166 U1 , Furthermore, in the DE 101 32 223 A1 proposed to integrate a silencer above the flues in a boiler.

All However, known silencer variants are independent of room air operated heaters not or only with considerable effort use. These heaters also have a burner, a combustion air or exhaust fan provided. By default but is a room air independent operated heater connected to a so-called air / exhaust system, in which in an internal exhaust pipe, the exhaust discharged to the outside is and in a surrounding outer tube cross-section the combustion air passes in countercurrent to the heater. Such systems settle because of the ease of installation of the tube-in-tube arrangement and the low investment costs more and more. The Air / exhaust systems are either pulled up over the roof or form the connection between heater and chimney, if only one exhaust pipe is laid in its shaft and the remaining cross-section serves as a channel for the air supply.

Of the Innovation is based on the task of creating a simply structured, universally applicable silencer for one to create room-independent heating device.

Innovation was this is achieved with the features of the protection claim 1. Advantageous developments are to be taken from the subclaims.

Of the Muffler is characterized by a modular Construction with a to be inserted in the air / exhaust pipe, known tee for an air / exhaust pipe. It is on the lateral branch of the tee a at least partially fillable with an insulating material Pipe extension attached. This forms a chamber, which with the inner exhaust pipe of the air / exhaust gas line is in communication and the surrounding outer tube cross-section for tightly seals the combustion air at the lateral branch. The at least partially filled with an insulating material Pipe extension has at the transition from the chamber to the inner Exhaust pipe in the lateral branch of the tee a perforated boundary wall or a grid, in particular to enclose the insulating material. At the outer end, the tube extension has a detachable Cover on. In this and / or in the wall of the pipe extension are perforations and / or spouts for the exit arranged by condensate of Schalldämmpackung, which used or closed depending on the mounting position of the silencer become. Steel wool is preferably used as an insulating material in the pipe extension or the chamber formed therewith.

With The design according to the innovation becomes simple built-up, universally applicable silencer for created a room air independent operated heater, which integrate well with known air / exhaust systems as an additional module leaves and can be admitted with these, because a suitable T-piece is used as a standard component. This is the installation effort minimal and also the subsequent installation can be done easily. The flow cross section of Exhaust pipe is not reduced and the space requirement is low, also because of the renewal of the muffler together with the T-piece in a cheapest possible Installation position in the area behind, beside or above the heating device to turn. Another advantage is the possibility nor the silencer according to the invention directly at the place of installation, that is, when commissioning a heater noise problems were determined to adjust. This can be done, for example Shortening or lengthening the pipe extension or by changing the insulation filling, especially with regard to type, quantity, packing density and arrangement in the chamber formed in the tube extension, take place.

The Drawing represents an embodiment of the innovation. It shows a silencer for connection to an air / exhaust system for a room air independent operated heating device:

1 : in a perspective view and

2 : in a vertical section.

The silencer consists essentially of a to be inserted in an air / exhaust pipe tee 1 , in the inner exhaust pipe 2 the exhaust gas of the heater is discharged to the outside and in the surrounding outer tube cross-section 3 the combustion air is supplied in countercurrent to the heater.

On the side branch of the tee 1 is one with an insulating material 4 fillable pipe extension 5 with a closure lid 6 attached. At the transition from the one with insulation 4 filled chamber to the inner exhaust pipe 2 there is a perforated boundary wall 7 , Furthermore, in the cap 6 and in the wall of the pipe extension 5 Breakthroughs and / or nozzles 8th arranged for the discharge of condensation.
