Description

Funnel for a condensing Gas Boiler}

The present invention relates to a gas boiler. In particular, in the condensing gas boiler adopted in the independent heating method, it is related to the communication used to supply the air necessary for combustion to the inside and exhaust gas generated from the inside to the outside.

In general, heating is divided into independent heating and central heating. In general, independent heating is used for small group houses such as independent houses or townhouses, and central heating is used for large group houses such as apartments. However, in recent years, in consideration of the problem of centralized central heating system uniformly, household boilers such as small gas boilers are provided for each apartment so that tenants can properly adjust the heating conditions as needed. It is a new trend to adopt so-called independent heating, which is installed and conducts heating.

On the other hand, in the case of the central heating system, only one relatively large stack is installed in the boiler room. However, when the independent heating system is used, a separate communication system must be installed for each boiler.

This communication, in addition to the basic function of the supply of air for the smooth combustion of the boiler and the efficient exhaust to prevent the indoor pollution, as it is the finishing material of the house itself has a great impact on the appearance of the house. Especially in the case of high-rise apartments, if the communication installed in each house is not correctly arranged and aligned, the appearance of the apartment itself will be damaged.

In the case of condensing gas boilers, which are widely used in homes, the structure allows the secondary absorption of waste heat by passing through the main heat exchanger and passing the exhaust gas through the secondary heat exchanger once more than other conventional boilers. It has a special feature and merit that can greatly improve thermal efficiency, and its diffusion rate is increasing day by day.

In the case of such a condensing gas boiler, the temperature of the exhaust gas discharged to the outside through the communication is about 55 to 60 ° C, and a large amount of condensed water is generated by the temperature difference between the exhaust gas and the air (air supply) supplied from the outside. The treatment of condensate is a new problem.

Thus, in order to solve such a problem in the related art, as shown in FIG. 1, the communication 1 is installed to protrude to the outside through the through hole H formed in the outer wall W, but the outer end when looking at the horizontal position as a reference Is lower than the inner end (approximately 3 ° inclination), so that the downward inclination is made so that the condensate generated inside the communication (1) flows down the inner downward inclined surface of the communication (1) to fall outwards The condensate generated at the rear end of the inner end flows into the inside of the boiler not shown as the rear part of the communication unit 1 and is discharged to the outside through the discharge means located in the boiler.

However, as described above, the method in which the outer end of the communication 1 is inclined downward may discharge the condensed water generated in the inside of the communication 1 to the outside through the outer end. It is undesirably desirable to contaminate the outer wall (W) while falling, and in the case of townhouses or high-rise apartments, the communication (1) installed in each house is constructed at a predetermined position. Not only is it undesirable in appearance by polluting the exterior walls and windows of each house, but also causes various problems such as frequent disputes and disputes between neighbors.

The present invention has been researched and developed in order to solve all the problems caused by the external discharge of condensate water through the outer end of the communication in the prior art as follows.

The main object of the present invention is to provide a communication of the condensing gas boiler that can be discharged by utilizing the discharge means of the condensate located inside the boiler without discharging the condensate generated in the communication to the outside of the communication.

Another object of the present invention is to provide a communication of the condensing gas boiler to minimize the inflow of rainwater or other pollutants from the outside to the inside of the communication.
