Abstract

Heater, comprising a flow guide (1) for emerging during combustion of fuel exhaust gas and a pneumatically connected to avoid thermal acoustics with the flow guide (1) resonator (2), wherein at the flow guide (1) a discharge port (3) for from the Exhaust condensate is provided, characterized in that the resonator (2) on one of the flow guide (1) facing away from the discharge port (3) is arranged.

Description

The invention relates to a heater according to the preamble of claim 1 protection.

A heater of the type mentioned is from the document DE 10 2006 004 372 A1 known. This heater consists of a flow guide for emerging during combustion of fuel exhaust gas and a pneumatically connected to avoid thermal acoustics with the flow guide resonator, wherein at the flow guide a discharge port is provided for accumulating from the exhaust condensate.

The invention has for its object to improve a heater of the type mentioned. In particular, a more effective device to avoid noise on the heater to be created.

This object is achieved with a heater of the type mentioned by the features listed in the characterizing part of the protection claim 1.

According to the invention, it is thus provided that the resonator is arranged on a side of the discharge connection facing away from the flow guide.

In other words, the resonator is thus not arranged in the area directly traversed by the exhaust gas, but at its periphery. More specifically, a flow guide for exhaust gas of the heater on a discharge port for accumulating condensate. At this discharge port then a drain line is connected, which, apart from the actual combustion chamber of the burner of the heating system, is formed connected to a resonator.

Other advantageous developments of the heater according to the invention will become apparent from the dependent claims.

For the sake of completeness, reference is also made to a further document attached to the application documents, which is published under http://dx.doi.org/10.4421/PAPDEOTT002947 can be downloaded: In this document, an exhaust gas resonator to avoid thermoacoustic vibrations is mentioned, but which sits directly on the exhaust port and not, as provided here according to the invention, outside the discharge port.

The heater according to the invention including its advantageous developments according to the dependent claims is described in more detail with reference to the drawing of a preferred embodiment.

It shows

1 in side view, a discharge line for the heater according to the invention arranged thereon resonator; and

2 the heater according to the invention with discharge line and resonator after installation in a housing of the heater.

This in 2 heater shown consists of a flow guide 1 for exhaust gas produced during combustion of fuel and one for avoiding thermal acoustics with the flow guide 1 pneumatically connected resonator 2 , wherein at the flow guide 1 a discharge connection 3 is provided for arising from the exhaust condensate.

Essential for the heater according to the invention is now that the resonator 2 on one of the flow guide 1 opposite side of the discharge port 3 is arranged.

Preferably, this is the flow guide 1 formed as an exhaust gas in the flow direction of a combustion chamber enclosing heat exchanger downstream exhaust gas collection chamber formed and the discharge port 3 at a lowest point of the flow guide 1 arranged.

Furthermore, it is preferably provided that the discharge port 3 for removing the condensate with a discharge line 4 - Optionally, a drain pipe piece or Abflußschlauchstück - is formed connected and that at the discharge port 3 one on the one hand with the discharge line 4 and on the other hand with the resonator 2 connected crotch 5 is provided. Here is the resonator 2 preferred as at one end to the crotch 5 formed open and closed at the other end pipe section. It's also a fork 5 open end formed as the lowest point of the pipe section.

In a preferred embodiment, it is further provided that the pipe section, depending on the frequency of sound to be suppressed, an inner tube diameter of at least 15 mm, preferably 20 mm, and an inner tube length between 100 and 600 mm, preferably 140 mm. The resonator 2 can, what is not shown separately, in particular as at the discharge line 4 arranged Helmholtz resonator may be formed.

Regarding the discharge line 4 is preferably a fork 5 open end as highest point of this discharge line 4 educated. Likewise, if necessary, the discharge line 4 and the resonator 2 in one piece, preferably made of plastic. Furthermore, it is preferred at one of the crotch 2 opposite end of the discharge line 4 a pipe connection interface 6 arranged.
