Description
BURNER FOR GAS BOILERS
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates in general to a burner for gas boilers and, more particularly, to a structural improvement in such a burner for improving both the productivity and operational stability of the burner by assembling die-cast top and bottom covers into the burner.
Description of the Prior Art In a typical burner for gas boilers, gaseous fuel is supplied to the burner and ignited by a high pressure igniter thereby being burnt up to generate thermal energy. Fig. 6 is a schematic view of a typical burner for gas boilers and Fig. 7 is a sectional view showing the construction of the above burner. As shown in the drawings, the typical burner 21 includes a bottom cover 24 which is formed by pressing. The center of the above bottom cover 24 is embossed to form a combustion tub mount 25. A combustion tub 26 is vertically mounted to the above mount 25. The combustion tub 26 is surrounded by an air diffusion panel 22. The above panel 22, which is fitted over the combustion tub 26 and supported by a cylindrical holder 23, is uniformly perforated thereby forming a plurality of air diffusion holes 22A. In the
above burner 21, the air diffusion panel 22, cylindrical holder 23 and bottom cover 24 form a burner housing which is provided with a combustion air chamber. In order to supply external air or combustion air to the combustion air chamber of the burner housing, the burner 21 also includes an air inlet member 27. The air inlet member 27 is set in a side section of the burner housing and communicates with the above combustion air chamber.
In the above burner 21, the bottom cover 24, air diffusion panel 22, cylindrical holder 23, combustion tub 26 and air inlet member 27 are separately formed by pressing. After forming the parts of the burner 21, that is, the bottom cover 24, air diffusion panel 22, cylindrical holder 23, combustion tub 26 and air inlet member 27, the above parts are assembled into the burner 21 by bolting and welding. That is, the bottom cover 24, air diffusion panel 22, cylindrical holder 23 and air inlet member 27 are assembled into the burner housing. Thereafter, the combustion tub 26 is mounted to the burner housing thereby forming the burner 21.
However, as the parts of the typical burner are separately formed by pressing and assembled into the burner, the process for producing the burner is complicated, thus reducing the productivity of the burner. In addition, it is difficult to manage the parts of the burner while producing the burner as the burner comprises several parts. Another problem of the above burner is
resided in that gaps and play are formed between the assembled parts of the burner due to the assembling allowance of the parts. Due to the above gaps and play formed between the assembled parts, the burner fails to mix the fuel with the combustion air at the predetermined ratio. In this case, the burner causes incomplete combustion and gas leakage which may cause a safety accident.
SUMMARY OF THE INVENTION
It is, therefore, an object of the present invention to provide a structurally improved burner for gas boilers in which the above problems can be overcome and which comprises die-cast top and bottom covers assembled into the burner, thus reducing the number of parts of the burner and simplifying the forming and assembling process of the burner and preventing combustion air from leaking from the burner.
In order to accomplish the above object, the present invention provides a burner for gas boilers comprising die-cast top and bottom covers which are assembled together into the burner. The above bottom cover, which is formed of aluminum by diecasting, is provided with a combustion tub mount. The above bottom cover, which is formed of aluminum by diecasting, is provided with an air inlet and an air diffusion panel having a plurality of air
diffusing holes. The air diffusion panel is formed on the center of the top cover, while the air inlet is formed on a side section of the top cover and communicates with a combustion air chamber defined by the top and bottom covers. As the burner of the present invention is formed by assembling the die-cast top and bottom covers, the burner is easily formed and assembled and prevents combustion air leakage.

Figs. 1 to 5 show a burner for gas boilers in accordance with a preferred embodiment of the present invention. As shown in the drawings, the burner 1 of the present invention comprises three parts, that is, die-cast top, bottom and hatch covers 2, 8 and 8a which form a burner housing. Each of the above top, bottom and hatch covers 2, 8 and 8a is formed into a single body by diecasting. The die-cast bottom cover 8 has a combustion tub mount 9. The above tub mount 9 is integrally formed on the center of the bottom cover 8. The bottom cover 8 also has a plurality of tub holders 11 which integrally stand on the cover 8 around the tub mount 9. A longitudinal opening 15 is formed on the bottom cover 8 outside the tub holders 11. The hatch cover 8a engages with the bottom cover 8 at their facing ends in order to cover the bottom of the burner housing. The two covers 8 and 8a have step portions 28 at their facing ends. The top surface of the above hatch cover 8a includes a Venturi tube holder 12 for holding a Venturi tube 17. Meanwhile, the die-cast top cover 2 is assembled with the above bottom and hatch covers 8 and 8a into the burner housing. The top, bottom and hatch covers 2, 8 and 8a also define
a combustion air chamber in the burner housing. The above top cover 2 has an air diffusion panel 3 which is integrally formed on the center of the top cover 2. The above panel 3 is uniformly perforated to form a plurality of air diffusing holes 4. The top cover 2 also has an air inlet 6 which is formed on a side section of the top cover 2. The air inlet 6 communicates with the combustion air chamber. A circular groove 20 is formed on the top cover 2 about the air diffusion panel 3. A valve 24 fits into a side wall of the top cover 2. The above valve 24 fixes a gas supply pipe 22 to the top cover 2.
Each of the bottom and hatch covers 8 and 8a has a plurality of fitting flanges 13. These fitting flanges 13 are formed on the edges of the covers 8 and 8a. Meanwhile, the lower edge of the above top cover 2 has a plurality of fitting slots 7 which are formed at portions corresponding to the fitting flanges 13 of the covers 8 and 8a. The fitting flanges 13 of the covers 8 and 8a are tightly inserted into their associated fitting slots 7 of the top cover 2, thereby assembling the top, bottom and hatch covers 2, 8 and 8a into the burner housing. Due to the above fitting slots 7 and flanges 13, the top, bottom and hatch covers 2, 8 and 8a are easily assembled together into the burner housing. In the drawings, the reference numeral 5 denotes a central opening of the air diffusion panel 3 adapted for receiving the combustion tub 16, and 14 denotes a bolt
hole formed on each of the top and bottom covers 2 and 8, and 10 denotes a fixing hole formed on the combustion tub mount 9 for fixing a combustion tub 16 to the mount 9, and 17 denotes the Venturi tube which extends to the combustion tub 16 in order to supply gaseous fuel to the tub 16.
The operational effect of the present invention will be described hereinbelow.
In accordance with the present invention, each of the covers 2, 8 and 8a is formed by diecasting. In the top cover 2, the air diffusion panel 3 having the air diffusing holes 4 for diffusing combustion air is integrally formed on the center of the top cover 2. In addition, the air inlet 6 for introducing the combustion air to the combustion air chamber is formed on a side section of the top cover 2. On the other hand, the bottom cover 8 has the combustion tub mount 9 for mounting the combustion tub 16. The above mount 9 is integrally formed on the center of the bottom cover 8. In order to support the bottom edge of the combustion tub 16, the plurality of tub holders 11 stand on the cover 8 around the tub mount 9. The hatch cover 8a has the Venturi tube holder 12 which holds the Venturi tube 17 extending to the combustion tub 16. After forming the above top, bottom and hatch covers 2, 8 and 8a, the covers 2, 8 and 8a are assembled into the burner housing by fastening with bolts through the bolt
holes 14 of the covers 2, 8 and 8a. In this case, the bottom and hatch covers 8 and 8a substantially engage with each other at their step portions 28. As the hatch cover 8a is attached to the top cover 2 separately from the bottom cover 8, the hatch cover 8a can be separated from the top cover 2 in order to expose the Venturi tube 17 outside the burner housing. Thus, the above hatch cover 8a makes it easy and fast to check or repair the Venturi tube 17. In addition, the valve 24 fits into the side wall of the top cover 2. Due to the above valve 24, the gas supply pipe 22 is stably and tightly fixed to the burner housing.
After assembling the top, bottom and hatch covers 2, 8 and 8a into the burner housing, the combustion tub 16 is mounted to the tub mount 9 of the bottom cover 8 by fastening with a bolt through the fixing hole 10. In the above case, the bottom edge of the combustion tub 16 is held by the tub holders 11 of the bottom cover 8. The Venturi tube 17 extending to the combustion tub 16 is held on the Venturi tube holder 12 of the hatch cover 8a.
When the combustion tub 16 is mounted to the tub mount 9 of the bottom cover 8 as described above, the top section of the above tub 16 projects out of the central opening 5 of the air diffusion panel 3 of the top cover 2.
In the above burner 1, an igniting unit 18 including an igniter and a flame sensor 18A is received in the
longitudinal opening 15 of the bottom cover 8. The above igniting unit 18 is fixed to the bottom cover 8 as shown in Fig. 4.
An combustion cover (not shown) is seated on the top cover 2 in order to form a combustion chamber and protect the combustion tub 16. In this case, the bottom edge of the above combustion cover is fitted in the circular groove 20 which is formed on the top cover 2 about the air diffusion panel 3. Due to the above groove 20, the combustion cover is easily and stably installed on the top cover 2.
As described above, the burner for gas boilers in accordance with the present invention includes top, bottom and hatch covers which are formed by diecasting. The die- cast top cover has an air diffusion panel and an air inlet. The die-cast bottom cover has a combustion tub mount, while the hatch cover has a Venturi tube holder. That is, the burner of this invention is formed by assembling the above die-cast top, bottom and hatch covers prior to mounting a combustion tub to the burner. The above air diffusion panel and air inlet are integrally formed in the top cover during the diecasting process of the top cover. In the same manner, the combustion tub mount and Venturi tube holder are integrally formed in the bottom and hatch covers during the diecasting process of the bottom and hatch covers. In this regard, the burner of this invention is easily formed and assembled. Due to
the hatch cover, it is easy to check or repair the Venturi tube. A gas supply pipe is stably and tightly fixed to the burner housing due to a valve which fits into a side wall of the top cover. The top cover has a fitting groove about the air diffusion panel. A combustion cover is fitted in the fitting groove and forms combustion chamber of the burner. Due to the above fitting groove, it is easy to form the combustion chamber. In addition, the die-cast top, bottom and hatch covers according to the present invention have a precise assembling allowance. The above top, bottom and hatch covers are thus precisely assembled into the burner housing, thereby allowing the combustion tub and igniting unit to be precisely mounted to the burner. Another advantage of the present invention is resided in that the burner prevents safety accidents caused by gas leakage.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
