Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an exhaust system for a combustion device.

(Conventional technology and problems) Conventionally, the exhaust port of the combustion device was opened at the front of the appliance.
In cases where the front cover is equipped with an exhaust guide and decoration plate, the part facing the exhaust port only has a horizontal part that guides the exhaust, and to prevent rainwater from entering the exhaust port, a rainproof plate is installed inside the exhaust port, and the part facing the exhaust port is placed diagonally upward. It was constructed to catch rain and raindrops that bounced off the plaque. Therefore, a rainproof plate was required, and additional man-hours were required for assembly.

The present invention aims to reduce the number of parts and improve ease of assembly by allowing the exhaust guide and decorative plate to also serve as a rainproof plate.

(Example) In the figure, 1 is a combustion device main body like a stationary bathtub with hot water supply, and an exhaust port 2 is opened in the front surface. Reference numeral 3 denotes an exhaust guide and decoration plate, which is provided over the entire width of the front cover 4. The decorative plate 3 includes a horizontal exhaust guide section 31, a fixed section 32 bent perpendicular to the exhaust guide section 31, and a fixed section facing the exhaust port 2 that is tilted diagonally upward toward the exhaust port 2. The rainproof part 33 and the exhaust guide part 3 are bent to
1 and a folded portion 34 formed on the front surface. 5
is an exhaust collecting pipe, which is airtightly connected to the front cover 4 by a collecting pipe flange 6 and forms an exhaust passage 7 to the exhaust port 2. 8 is a rainwater intrusion prevention plate;
Like the conventional one, it catches rainwater that has entered the exhaust port 2 and guides it out of the exhaust port 2. 9 is a fixing plate for fixing the decorative plate 3 to the front cover 4, 10, 11
is a sealing plate.

During assembly, the exhaust guide/decor plate 3 is fixed to the front cover 4 at its fixing portion 32 via the fixing plate 9 with screws or the like. On the other hand, the collecting tube 5, the collecting tube flange 6, and the rainwater intrusion prevention plate 8 are integrally formed by welding or the like as in the conventional case. When fixing the front cover 4 to the main body 1, the rainproof portion 33 of the decorative plate 3 may be inserted into the exhaust port 2.

The exhaust gas that has passed through the exhaust passage 7 passes through the rainproof section 33.
The gas is guided through the exhaust guide section 31 and the folded section 34, and is blown out diagonally downward from the front of the instrument. Rain that enters the exhaust port 2 from diagonally above is directed to the exhaust guide section 3.
1 It can be received on the top surface. and exhaust guide section 31
The raindrops that bounce off the top are caught by the rainproof part 33 and are discharged to the outside of the appliance as they are or to the outside of the exhaust port 2 after dripping onto the rainwater intrusion prevention plate 8.

(Effects of the invention) As described above, the present invention uses the part of the decorative plate facing the exhaust port, which was conventionally cut off, as a rainproof part, which eliminates the need for a separate rainproof plate. Since assembly can be done at the same time as fixing the decorative plate, the number of parts can be reduced and assembly efficiency can be improved.
