- the gas boiler according to the present invention has the following effects.
- the burner flange of the burner and the chamber flange of the gas supply chamber are shape-matched to surface-contact each other to allow heat of the burner itself to be dissipated to the chamber flange of the gas supply chamber when the burner operates, the overheating of the burner (particularly, the flange of the burner) may be prevented.
- the leakage of the pre-mixed gas that is supplied from the gas supply chamber to the burner may be prevented from leaking between the burner and the gas supply chamber by the sealing member disposed between the burner and the gas supply chamber.
- the burner flange may further stably surface-contact the chamber flange while being shape-matched to prevent the burner from being overheated through the heat-exchanging between the burner flange and the chamber flange.
- the sealing member may have a wide choice of materials.
- a special embodiment of the invention is provided with a heat dissipation fin. Since the heat dissipation fin is disposed between the burner and the gas supply chamber, the overheating of the burner may be further prevented by the heat dissipation fin that is cooled by the pre-mixed gas having a low temperature supplied from the gas supply chamber.
- Burner 111 Burner flange 130: Gas supply chamber 131: Chamber flange 133: Groove 150: Sealing member 151: Body 153: Protrusion 170: Heat dissipation fin
- FIGS. 1 to 4 A gas boiler according to an embodiment of the present invention is illustrated in FIGS. 1 to 4 .
- the gas boiler includes a burner 110, a gas supply chamber 130, and a sealing member 150.
- the gas boiler according to an embodiment of the present invention has a shape and structure as illustrated in FIG. 1 . Thus, accurate positions of the burner 110 and the gas supply chamber 130 in the gas boiler may be recognized with reference to FIG. 1 .
- the burner 110 may receive a pre-mixed gas to burn the pre-mixed gas.
- the burner 110 may receive the pre-mixed gas in which air is pre-mixed with a gas at an optimal combustion mixing ratio from the gas supply chamber 130 that will be described later.
- the pre-mixed gas may be completely burnt. Thus, the burner has high combustion efficiency and may realize complete combustion at a low air ratio.
- a metal fiber burner may be applied to the burner 110.
- An example of the metal fiber burner is disclosed in Korean Patent Publication No. 10-2002-0069530 .
- the above-described burner 110 is not limited to the shape thereof and may have various shapes. Also, a burner flange 111 may be disposed on a side surface of the burner 110 along a circumferential direction.
- the gas supply chamber 130 may supply the pre-mixed gas to be burnt by the burner 110 to the burner 110 as described above.
- the gas supply chamber 130 is seated on and coupled to an upper portion of the burner 110.
- a chamber flange 131 that is shape-matched to the burner flange 111 when the gas supply chamber 130 is seated on and coupled to the upper portion of the burner 110 is disposed on the gas supply chamber 130. Since the burner flange 111 has a shape that matches to that of the chamber flange 131, the burner flange 111 surface-contacts the chamber flange 131.
- each of the burner 111 and the gas supply chamber 130 is formed of a metal material. Since the burner flange 111 is shape-matched to the chamber flange 131, leakage of the pre-mixed gas supplied from the gas supply chamber 130 to the burner 110 may be prevented. However, since the leakage of the pre-mixed gas is not perfectly prevented by the shape-matched coupling of the burner flange 111 and the chamber flange 131, a component that is capable of preventing the gas from leaking is needed between the burner 110 and the gas supply chamber 130.
- a sealing member is disposed between the burner 110 and the gas supply chamber 130.
- the burner 110 may be slightly separated from the gas supply chamber 130 without being shape-matched due to the installation of the sealing member.
- the sealing member 150 according to the present invention solves the limitation. Therefore, the burner flange 111 of the burner 110 may be completely shape-matched and coupled to the chamber flange 131 of the gas supply chamber 130 so that the burner flange 111 surface-contacts the chamber flange 131. More particularly, the sealing member 150 is disposed between the burner flange 111 and the chamber flange 131 when the burner flange 111 is shape-matched to the chamber flange 131. Thus, a groove 133 is defined in the chamber flange 131 so that the sealing member 150 is disposed therein.
- the sealing member 150 includes a body 151, a protrusion 153 formed on the body 151.
- the body 151 has a width that is less than a height of the groove 133 so that the body 151 is inserted to the groove 13.
- the body 151 may have a column shape having a circular or rectangular section and various shapes.
- a plurality of protrusions 153 protruding from the body 151 is formed on the body 151.
- one portion of the protrusions 153 may be inclined toward an inner surface of the groove 133 defined in the chamber flange 131 of the gas supply chamber 130, and the other portion of the protrusions 153 may be inclined toward the burner flange 111 of the burner 110.
- the protrusion 153 of the plurality of protrusions 153 which is formed toward the chamber flange 131, may be inclined upward from the body 151.
- the protrusion 153 of the plurality of protrusions 153 which is formed toward the burner flange 111, may be inclined downward from the body 151. That is, the plurality of protrusions 153 are formed toward the insides of the gas supply chamber 130 and the burner 110.
- the plurality of protrusions 153 are disposed and installed toward the insides of the burner 110 and the gas supply chamber 130.
- the sealing member 150 may have a height that is greater than that of the groove 133 by the plurality of protrusions 153.
- the plurality of protrusions 153 may flexibly move to allow the sealing member 150 to be installed between the burner 110 and the gas supply chamber 130. That is, when the sealing member 150 is installed to the groove 133, as illustrated in FIGS. 3 and 4 , the plurality of protrusions 153 of the sealing member 150 may be installed to the groove 133 while being lain toward the body 151 in an arrow direction.
- the burner flange 111 of the burner 110 may be perfectly shape-matched and coupled to the chamber flange 131 of the gas supply chamber 130 even though the sealing member 150 is installed, and the burner flange 111 may surface-contact the chamber flange 131. Since the burner flange 111 surface-contacts the chamber flange 131, if a surface of the burner 110 is overheated because flames of the burner 110 have short lengths due to the combustion with a low heat generation amount, heat-exchanging may be performed between the burner flange 111 and the chamber flange 131 to prevent the burner 110 from being overheated.
- the pre-mixed gas supplied from the gas supply chamber 130 to the burner 110 may leak between the burner 110 and the gas supply chamber 130.
- the sealing member 150 when the sealing member 150 is disposed between the burner 110 and the gas supply chamber 130, the leakage of the pre-mixed gas may be prevented by the sealing member 150.
- the plurality of protrusions 153 formed on the sealing member 150 are formed toward the inside the gas supply chamber 130 and the burner 110, the plurality of protrusions 153 may prevent the pre-mixed gas from leaking once again.
- FIGS. 5 to 8 A gas boiler according to another embodiment of the present invention is illustrated in FIGS. 5 to 8 .
