Abstract

The utility model relates to a combustor assembly of a fuel gas cooker. The combustor assembly comprises an ejector, a fire cover base and a fire cover, wherein the fire cover base is integrally connected with the ejector, and the fire cover is of a 'bowl'-shaped structure and mounted on the fire cover base. An air outlet hole is arranged on the fire cover along a tangential direction of the fire cover, an included angle less than 90 degrees is formed between the air outlet hole and the inner surface of the fire cover, a heat insulation gasket is arranged between the fire cover and the fire cover base, a combustion guide plug is installed in a central through hole of the fire cover, a fire collecting ring is fastened at the upper end of the fire cover or/ and the upper end of the fire cover base, and the inner surface of the fire collecting ring is a circular conical surface. The combustor assembly is capable of preventing fuel gas from deflagrating in the ejector, simultaneously enhancing combustion strength of the flames of the combustor assembly and improving thermal efficiency of the cooker.

Description

The burner assembly of gas furnace kitchen range

Technical field

The utility model relates to the parts in a kind of gas furnace kitchen range, the particularly burner assembly of gas furnace kitchen range.

Background technology

Burner assembly is the core component in the gas furnace kitchen range, forms by injector with the burning jamb that injector combines as a whole.The burning jamb that a kind of burner assembly is arranged is an overall structure, offers some ventholes at the burner end face, and the combustion gas in the injector inner chamber comes out afterwards to mix with air and burn from this venthole.And the burning jamb of another kind of burner assembly is a fabricated structure, by the fiery cage that combines as a whole with injector be installed in the fire lid that is " bowl " shape structure on the fiery cage and form, offers venthole on the conical inner surface that fire covers.The burner assembly of this kind structure directly contacts with fiery cage owing to the fire lid is installed on the fiery cage, the high temperature that the fire lid produces during the air mixture burning is easy to be passed to fiery cage, thereby the temperature of injector is raise, if combustion gas must mix with air in the injector inner chamber, detonation then easily takes place in injector.And, existing burning jamb structure, the venthole that combustion gas covers from the fire formed flame of after-combustion that comes out is weak, makes the thermal efficiency of kitchen range low.

The utility model content

The purpose of this utility model provides a kind of burner assembly of gas furnace kitchen range, in the injector of burner assembly detonation takes place to avoid combustion gas, strengthens burner assembly flame burning dynamics simultaneously, improves the thermal efficiency of kitchen range.

The burner assembly of gas furnace kitchen range described in the utility model, comprise injector, the fiery cage that combines as a whole with injector, and be installed in the fire lid that is " bowl " shape structure on the fiery cage, on the conical inner surface of fire lid, offer venthole, the center of fire lid offers through hole, described venthole is offered and is angle less than 90 ° with fiery interior surface along fire lid tangential direction, between Huo Gai and fiery cage, be provided with heat insulating washer, burning guiding plug is installed in the central through hole of fire lid, fire-collected ring, the inner surface of fire-collected ring are arranged is taper seat or/and fiery cage upper end fastens to cover end at fire.

The burner assembly of gas furnace kitchen range described in the utility model is owing to be provided with heat insulating washer between Huo Gai and fiery cage, the high temperature that the fire lid produces during the air mixture burning just can not pass to fiery cage, make fiery cage can remain lower temperature, so even combustion gas mixes with air in the injector inner chamber, air mixture also can not lighted in injector and be produced detonation.

Because the venthole that covers of fire is offered and is angle less than 90 ° with fiery interior surface along fire lid tangential direction, and its center is provided with burning guiding plug, flame is not directly to cover to upper punch from fire, but be angle direction ejection less than 90 ° along the tangential direction of fire lid conical inner surface and with this inner surface, after burned guiding plug and fire-collected ring stop, warm oneself in front of a fire to cover and rise to upper punch after assemble the top, center, make flame be the burning of whirlwind shape, so can make flame combustion strong, improve the thermal efficiency of kitchen range effectively.

The specific embodiment

As shown in Figures 1 to 4, the burner assembly of these gas furnace kitchen range comprises injector 1, the fiery cage 6 that combines as a whole with injector 1, and be installed in the fire lid 7 that is " bowl " shape structure on the fiery cage 6, on the conical inner surface of fire lid 7, offer venthole 4, the center of fire lid 7 offers through hole, described venthole 4 is offered and is covered 7 inner surfaces with fire along fire lid 7 tangential directions and is angle less than 90 °, between fire lid 7 and fiery cage 6, be provided with heat insulating washer 2, burning guiding plug 3 is installed in the central through hole of fire lid 7, at fiery cage 6 upper ends fastening fire-collected ring 5, the inner surface of fire-collected ring 5 being arranged is taper seat.

Fire-collected ring 5 also can be fastened on the upper end of fire lid 7, or is fastened on fiery cage 6 and fire lid 7 upper ends simultaneously.

Claims

1, a kind of burner assembly of gas furnace kitchen range, comprise injector (1), the fiery cage (6) that combines as a whole with injector, and be installed in the fire lid (7) that is " bowl " shape structure on the fiery cage, on the conical inner surface of fire lid, offer venthole (4), it is characterized in that: the center of fire lid offers through hole, described venthole is offered and is angle less than 90 ° with fiery interior surface along fire lid tangential direction, between Huo Gai and fiery cage, be provided with heat insulating washer (2), burning guiding plug (3) is installed in the central through hole of fire lid, covering end at fire has fire-collected ring (5) or/and fiery cage upper end fastens, and the inner surface of fire-collected ring is a taper seat.
