Definitions

  • the present invention relates to a tubing assembly and more particularly, to tube orifice and orifice holding assembly improvements.
  • EP2183520 discloses a tubing assembly for a burner according to the preamble of claim 1.
  • Figure 1 shows an orifice holder assembly 10 having an orifice holder 12 which is typically a cast part, and in the preferred embodiment, has been cast out of aluminum. Of course, other manufacturing techniques could be utilized to make other orifice holders. Casting has been found to be economical while providing a quality product.
  • the orifice holder 12 has an outlet 14, shown in Figure 2 , at a top end 16.
  • the outlet 14 of this disclosure is illustrated as being at least substantially round and directs a fuel gas mixture from below through the outlet 14 past the top end 16 for use by a burner which is not shown. Many burner designs have been constructed. Other orifice holders have been utilized in the past for such uses.
  • This orifice holder has two arms 18,20 which are shown in Figure 3 , at least substantially symmetrically extending from a base 22. These arms 18,20 connect at a boss 24 which is configured to have a bore therethrough which receives a portion of tube 26 therethrough.
  • a bead 28 is preferably utilized to stop the tube 26 a desired position relative to the boss 24 as shown in Figures 3 and 4 during the assembly process.
  • Other mechanisms known in the art can also be utilized which provide a stop so that no further travel of the tube 26 through the bore can occur due to the presence of the bead 28.
  • an anvil 30 or other device is inserted through the outlet 14 of the orifice holder 12 and causes the end 32 of the tube 26 to be deflected such as shown in Figure 4 so that the boss 24 of the orifice holder is secured relative to the lip 34 created by the bent tube 26 and the bead 28.
  • This method of construction is believed to be a large improvement over the prior art in that in the prior art such as shown in U.S. Patent Nos. 5,607,194 and 5,727,303 .
  • the bead 28 has a boss engagement flange 36 which is shown adjacent to boss surface 38 and lip 34 as a lip engagement surface 40 which engages boss surface 42. Additionally, arms 18,20 are illustrated extending above the lip 34 as well as above orifice body 46.
  • the tube end 32 After connecting the tube 26 to the orifice holder 12, if the tube end 32 is not already provided with threads is may be tapped so that it has threads 44 as shown in Figure 4 by directing the tap (not shown) through the outlet 14 and providing the threads 44 as shown in Figure 4 in a similar manner as anvil 30 is shown applied in Figure 3 .
  • the orifice body 46 may make its own threaded connection (i.e., somewhat self tapping). The orifice body 46 with its cooperating threads is then inserted preferably through the outlet 14 so that its cooperating threads engage threads 44 so it can be provided in the position shown in Figure 4 .
  • the orifice body 46 then has bore 48 which allows for the gas from the tube 26 to then mix with air in the space 49 prior to being directed through the outlet 14 where mixing can further continue to occur within a burner (not shown) before being lit and providing heat in a stove type configuration.
  • the presently preferred embodiment as described herein provides the connection of the tube 26 to the boss 24 through application through the outlet 14 as well as the machining of the tube 26 to provide threads 44 if not done prior to the installation of the tube 26 to the boss 24. Finally it is also presently preferred to install the orifice body 46 through the outlet 14.
  • the orifice holder 10 is connected to a stove top 62 or 64 (but not both) as shown with at least one shoulder 50. Both an on top and a to bottom connection are shown in Figure 1 . Obviously, one of the two would be selected.
  • Connector 66 is a screw connected through the stove top 62 to a nut 68 but could be similarly connected to stove top 64 as would be understood by those of ordinary skill in the art through one or more bores 52.54 through one or more shoulder(s) 50. A similar or dissimilar connection could be provided when connecting to stove top 64.
  • the stove top 62 or 64 would have a bore, such as one of bores 70,72 so that a gas/air mixture would proceed from the orifice body 46 through the outlet 14 with the mixing beginning below the stove top 62 or 64. Additionally a bore would be located through either of the stove tops 62 or 64 in many embodiments so that an ignitor 60 could proceed through the passage 56 (which shows three possible locations, there certainly could be other passage constructions to accommodate ignitors, such as 60.
  • the passage 56 is preferably provided through an extension 57 integrally formed (i.e., casted) with much of the remainder of the orifice holder 10.
  • the extension 57 can be between the shoulders 50 as illustrated or otherwise provided.
  • a burner ring (not shown) can rest on top of the slanted surfaces 80 about the outlet 14 to direct a ring of flame above the stove top ( 62 or 64 ).
  • Other embodiments have the orifice holder 10 connected to an underside of the of a bottom planar surface of the burner casting (i.e., the bottommost part in most constructions, which is essentially almost coplanar with the remainder of the stove top 62 ) which effectively provide a portion of the stove top 62 shown in Figure 1 to which the orifice holder 10 connects from below.
  • the orifice body 46 is below, and preferably spaced below, the stove top 62 or 64.
  • FIG. 5 shows a first alternatively preferred embodiment of the present invention.
  • the burner 101 connects to a cooktop 102 and provides flame orifices 121 through which flames originate when a fuel/air mixture is ignited as occurs with the embodiment above and other burners 101 used with cooktops 102.
  • the burners 101 are used normally as a portion of gas cooking appliances such as cooktops, ranges, etc....
  • the burner ring 122 has the flame orifices and the cap (not shown) is removed for clarity but rests atop the burner ring 122 as is known in the art.
  • Injector or orifice 118 is illustrated being supported by an orifice holder cup 120.
  • a gas supply tube 106 provides gas, normally natural gas or propane, through the orifice 118 to enter the cavity 103 disposed above and about the orifice holder cup 120.
  • the tube 106 can be provided with a bead 107 which can contact a lower surface 105 of a boss 114. The tube 106 can then be bent to provide a lip 113 at upper surface 123 of boss 114 to connect the tube 106 to the orifice holder cup 120 as discussed above or otherwise.
  • Orifice body 104 can then be inserted into the tube 106 as occurs with the embodiment described above, or otherwise, such as through the lip 113 and have threads 109 which connect to an inner surface of the tube 106. Meanwhile outer surface 110 of tube 106 proceeds through an internal bore (along 110 ) of boss 108 as would be understood by those of ordinary skill in the art.
  • the burner 101 illustrated is an "air from top” burner 101, where all or a majority of the primary air utilized with combustion from the air/gas mixture emanating from the ports 121 of the burner ring comes from above the cooktop 102 (and not from below).
  • a majority could be defined as at least greater than 50%, at least 2/3, at least 3/4 or more than about 90% depending on the specific embodiment.
  • the orifice holder cup 120 can include one or more location(s) for burner mountings 111 and 119, one or more bases 115, 117 such as could be utilized to connect to the cooktop 102.
  • the connection of the cup 120 to the cooktop 102 are completely sealed connections which could, for many embodiments, provide for all of the air to be from above the cooktop 102. Other embodiments may provide for mostly sealed connections.
  • the burner cup 120 can be fully or mostly enclosed so that cavity 103 will not be affected by pressure changes below the cooktop (external to the cavity 103 ).
  • the boss 114 can be located underneath at a lower portion of the cup 120 and be connected to the burner inlet.
  • Tube 106 can be inserted at a certain length into the boss 114.
  • the bead 107 can provide for a positional stop on the inserted tube length.
  • the tube although typically by a mandrel, once inserted can be formed so that a portion of the tube 106 forms a lip onto the boss 114 to capture the placement.
  • the orifice body 104 can then be installed and can mechanically seal itself to a section of the tube 106 which has been captured in the boss 114.
  • this construction and assembly can eliminate one of the connection points of a typical orifice holder cup and therefore eliminate a potential gas leak pathway between the supply valve and metering orifice body 104.
  • this construction technique can also reduce cost and complexity of the cast or formed cup 120.
  • An orifice holder assembly may comprise a cast orifice holder of unitary construction having a base 111, 119 connected by a cup 120 to a boss 114, said boss 114 located at or towards a bottom portion of the cup 120 and having a bore 108 therethrough extending from a first boss surface 105 to a second boss surface 123 with said second boss surface 123 located above the first boss surface 105 , said base 111,119 having an outlet extending thereacross above the boss 114, with the boss 114 integrally connected by the cup 120 to the base 111 and/or 119, the base 111,119 having at least one shoulder 117 for connecting the orifice holder to a cooktop 102 .
  • a tube 106 may be received by the boss 114, said tube 106 having a preformed bead 107 disposed about the tube 106 spaced from a tube end, said bead 107 contacting the first boss surface 105 with a portion of the tube 106 extending through the bore 108 of the boss 114, said tube 106 then deformed at the tube end to provide a lip 113 with a lip engagement surface in contact with the second boss surface 123 external to the bore with the lip 113 and the bead 107 forming a mechanical connection of the tube 106 to the boss 114 by entrapping a portion of the boss 114 between the lip 113 and bead 107 .
  • an orifice body 104 may be connected to the tube end and having a bore therethrough, said orifice body 104 located below the base 111 and 119 with a cavity 103 above the orifice body 104 and below the base 111 and/or 119 and said orifice body 104 terminating internal to the boss 114 above the first boss surface 105, wherein the cup 120 extends from the base 111,119 to the boss 114, wherein the base 111,119 and the boss 120 are longitudinally separate and the cup 120 extends from an internal perimeter of the base 111,119 to an external perimeter of the boss 114, and at least 50 percent of air mixed with fuel from the orifice body 104 is received from above the cooktop 102.
