Definitions

  • the present invention relates to a production method of a burner assembly used on gas cooker appliances and having a two-piece base, such as the one disclosed in WO 2005/073630 A1 .
  • a burner assembly is mounted to the mounting holes on the burner plate in gas cooker appliances.
  • the burner assembly mixes the ambient air with the flammable gas supplied from an injector through which a flammable gas is circulated by a gas pipe, and provides the heat energy required for the cooking process by burning it through a flame distributor in such a way to form a flame crown.
  • Parts forming the burner assembly are generally produced by metal injection or casting.
  • the gas burner bases which consist of two parts, namely a lower body and an upper cover attached to it, lose some of their flatness during injection or during cooling. These faulty surface junctions that form during the joining of two metal parts may cause some gas leakage that occurs during the initial start-up of the combustor or when it reaches a high temperature, which is revealed only during quality control. If the user does not operate under appropriate standards, this gas may accumulate in the closed volume of the furnace or oven, causing the risk of reaching the flash point when conditions are met.
  • the objective of the invention is to extend the gas tight life between the cover and the lower body in burner assemblies comprising a cover and a lower body.
  • the material melting temperature of the cover is greater than the lower body melting temperature.
  • the cover along the rim is heated along the junction line where the lower body comes into contact at a high temperature, preventing the corresponding part of the cover from melting and losing its form.
  • the cover preferably has a flat plate structure. Thanks to the high melting temperature, a deformation of the flat plate structure is prevented that may cause bending or twisting due to melting or thermal stress.
  • the cover and the lower body comprise a metal, particularly aluminum alloy. Due to its high adhesion capability in the molten state, the aluminum alloy makes the integration possible directly with the adhesion of the rim part to the cover, without the need to apply another process in the junction line.
  • a burner assembly produced as described above comprises a lower flange extending along the circumferential edge of the lower body and an upper flange which corresponds to the lower flange on the cover and aligned with the lower flange (22) on top of each other, between which a junction line is provided.
  • the lower flange and the upper flange increase the sealing properties by providing a high radial junction line with planar surfaces that sit on each other.
  • the extended lower and upper flange parts display fast cooling properties after injection and provide rapid cooling and integration in a way that increases the production speed in case the lower part is injected into the upper cover from the upper flange.
  • the gas inlet and the transfer channel are arranged essentially perpendicular to each other.
  • a lower body and a cover structure suitable for a burner assembly comprising a horizontal or partially angled injector can be obtained.
  • the gas inlet may be located at the bottom of the lower body.
  • a suitable area can be created for the mounting of multiple injectors with one or more gas inlets.
  • the lower flange comprises a barrier extending circumferentially upward at its outer edge and delimiting a pool, and the upper flange is arranged in such a way that leans against the barrier from inside from a radial outer part thereof.
  • the barrier helps the cover to wrap the cover not only in the radial direction with the junction line, but also axially.
  • the sealing cross section is extended, for example forms an L-like structure.
  • the burner assembly comprises a tab extending radially outwardly on the outer part and a groove correspondingly wrapping the tab in the barrier. In this way, the contact surface of the barrier with the cover increases from the corner of the barrier and the cover is provided to be strongly integrated into the lower body after injection.
  • junction line is in a circular strip structure.
  • sealing between the container-shaped lower body and the cover is provided circumferentially.
  • FIG. 1 a representative embodiment of the burner assembly produced by means of the method of the invention is shown by taking a cross section in the integrated state after injection in a schematically given mold (40).
  • the burner assembly comprises a lower body (20) in the form of a container covered in a gas-tight manner by a cover (10) and a flame distributor (30) placed on the cover (10).
  • the lower body (20) is fixed on the burner plate (not shown) of a cooker with the cover (10).
  • the cover (10) is in the form of a circular flat plate.
  • the cover (10) is attached to the mold (40) in the form of an insert.
  • FIG 2 the part A provided in Figure 1 is shown as enlarged.
  • the cover (10) is obtained by extending the upper flange (12) to form a barrier (25) in the form of an upward protrusion that limits the outer part (15) of the lower flange (22) in the form of a radial strip.
  • An inward groove (21) is formed on the inner wall of the barrier (25), in such a way that forms a level with the lower corner (13) part.
  • a tab (11) formed on the edge of the upper flange (12) near the lower corner of the outer part (15) is placed in the groove (21).
  • the tab (11) is placed in the groove (21) to fit perfectly.
  • the lower surface (17) of the upper flange (12) is planar.
  • the corresponding seating surface (27) of the lower body (20) placed on the lower surface (17) is also planar.
  • the metal injection mold (40) supports the upper flange (12) internally with the help of a core (not shown) leaning against the inner wall (23), and the aluminum alloy injected into the lower surface (17) adheres to the seating surface (27) without melting the cover (10), and cools in such a way to form the lower flange (22).
  • the cover (10) is integrated with the lower body (20) and is combined with the flame distributor (30) to be used in the burner assembly.
