Definitions

  • the invention relates to burners used in domestic cooking appliances, e.g. cookers, ovens, etc.
  • the burners used in domestic cooking appliances basically consist of at least three individual parts, which are a pool, at least one flame crown and at least a cap (i.e. lid or cover).
  • the adapter consists of two parts, one of which is a base mounted on said pool, and the other is a flame crown made of brass material and provided with ports thereon.
  • a cap is placed on the adapter or flame crown.
  • Cap is the enamelled part which has a specific surface form fitting onto the flame crown.
  • these burner lids which are located on the ports, where the flame exits, can have different designs.
  • the lids in the burners also increase the heat transfer to the object placed on it by keeping the heat within the burner.
  • the better the cap fits onto the flame crown the smoother the flame exits through the ports; and the union of the flames exiting from successive ports is prevented. Again, burning is adversely affected by any distortion (run-out) or deformity occurring on the cap, adapter or flame crown, and therefore it causes big flames to go out from some ports.
  • the invention relates to a burner with a new cap design which can be used in domestic cooking appliances and which aims to eliminate all of the above mentioned problems, said cap being made of aluminum, brass, ceramic, porcelain, or glass material, or being applied teflon or ceramic coating thereon.
  • the application owned by the firm Sabaf S.p.a and numbered WO 2004/102072 discloses a burner (1).
  • said cap (5) and body (3) are produced separately.
  • the cap (5) having a convex form is mounted on a body (3) by means of bolts (21).
  • This method is quite demanding; moreover, in addition to causing time losses during production, it is difficult for housewives to dismount/mount it when they want to clean it.
  • the cap is produced as a single-piece together with the ports and it can be easily located on the base by means of the cavities provided on the lower surface of the cap. Thus, there is no need for housewives to remove bolts for cleaning the burner or for any other reason.
  • the patent application owned by the firm Electrolux Home Products Corporation and numbered EP 1 703 203 also discloses a burner.
  • the cap (14) and the flame crown (12) are produced separately.
  • a cap (14) with a flat surface is placed on the toothed crown. Due to any distortion or deformity likely to be experienced during the production of the cap (14), the cap may not be properly placed on the flame crown (12). Therefore, flames will not properly exit the ports and flame unions in some consecutive ports will be experienced. This is an undesired situation in burners.
  • ports are located in the lower surface of the cap and the cap can be produced of aluminum, brass, ceramic or glass material, as a single piece together with these ports.
  • cap and ports are produced in a way fully compatible with each other, thereby preventing possible distortion between the cap and ports.
  • the flame crown where ports are provided, and the caps are commonly produced separately, and then the caps are placed on the flame crown by being mounted thereon.
  • the flame crown is made of aluminum or brass material, white the cap is the enamelled burner component. Since these components are produced by different production methods, distortions and deformities occurring during production adversely affect the burning, causing serious potential problems regarding proper burning, providing the pot placed thereon with homogeneous heat transfer, etc.
  • the flame crown ring, where ports are provided, and the cap are produced as a single piece.
  • the bottom parts of the ports, through which the flame exists have either flat surface, or inclined surface at a certain angle facing upwards, where cooking pot is provided.
  • the port bases in our invention are designed such that they will be inclined downwards at a certain angle. Hence, the route of the flame is increased downwards and a more uniform burning is obtained.
  • the object of the invention is to provide a burner with a new cap design to be used as burners in domestic cooking appliances, e.g. cookers, ovens, etc.
  • Another object of the invention is to provide a burner having a cap design which can be made of aluminum, brass, glass, porcelain, or ceramic material as a single piece, wherein teflon or ceramic coating method can be applied on brass or aluminum materials.
  • Another object of the invention is to provide a burner with high thermal efficiency, thanks to the new cap design thereof.
  • the cap in said burner can be made of aluminum via injection moulding method, aluminum or brass via hot forging method, or of any one of the materials including glass, porcelain, ceramics, which are resistant to heat and thermal shock, as a single piece, alternatively it can be made of brass or aluminum material, and then applied teflon or ceramic coating thereon for providing thermal resistance, said cap comprising a convex upper surface, a port ring provided with ports through which the flame exits, and a convex lower surface provided with at least two C-shaped cavities radially scattered around its center in order for it to be easily mounted on the base.
  • At least two ridges provided on the base of the burner and radially scattered around the center thereof are formed such that a certain ridge outer length narrows down to a certain ridge inner length so as to allow it to be engaged in at least two C-shaped cavities in the lower surface of the cap.
  • a C-shaped cavity with a flat surface is provided in the periphery of the igniter bearing where the igniter is mounted, said cavity being provided in the skirt portion of the base provided in the burner.
  • the bottom of the ports on the port ring in the lower surface of the cap in said burner is inclined downwards such that the bottom angle (X) will be between 2 0 and 8 0 .
