Definitions

  • the invention relates to a gas main for a gas cooking appliance having an inner channelling for gas and comprising at an end a connecting tap for the connection to the gas pipeline network external to the appliance and, at least at a point between both ends of the main, a gas outlet opening to which a gas tap can be connected regulating a gas flow towards a cooking hob of the gas cooking appliance, which can circulate through the inner channelling from the connecting tap up to the gas outlet opening.
  • a gas cooking appliance such as a gas stove or a gas hob from patent EP 2857751 B1 can be connected to a gas supplying source, such as a gas pipeline network external to the appliance by means of a gas main to which gas regulating valves are connected, from which gas pipes lead gas to the gas nozzles, which form the cooking hobs of the gas stove together with the gas burners.
  • a gas supplying source such as a gas pipeline network external to the appliance by means of a gas main to which gas regulating valves are connected, from which gas pipes lead gas to the gas nozzles, which form the cooking hobs of the gas stove together with the gas burners.
  • the object of the invention is to provide an improved gas main for a gas cooking appliance.
  • a gas main for a gas cooking appliance having an inner channelling for gas and comprising at an end a connecting tap for the connection to the gas pipeline network external to the appliance and, at least at a point between both ends of the main, a gas outlet opening to which a gas tap can be connected regulating a gas flow towards a cooking hob of the gas cooking appliance, which can circulate through the inner channelling from the connecting tap up to the gas outlet opening, wherein the main has at its outer perimeter a side surface with at least a groove for a first body protrusion of a tap body of the gas tap to be connected to the same and the gas main is made in one piece.
  • a “main” refers to the conduit of the gas appliance into which gas flow from outside the appliance flows directly to be distributed towards the cooking hobs.
  • the main is substantially longitudinal and has two ends. Inside the main there is an inner channelling through which gas can circulate and extending at least over a part of the interior of the main and being opened to the outside at least at one of the ends of the main, a connecting tap being formed at said end by which connection to the gas pipeline network external to the appliance can be obtained by means of a connecting element.
  • the gas pipeline network external to the appliance may be a gas bottle or the gas pipe coming from the community gas pipeline network or any other conventional gas supply.
  • the main Located between its ends, the main has at least a gas outlet opening extending through a main side wall, which connects the inner channelling with the main outside.
  • the number of gas outlet openings depends on the number of gas valves or taps that can be connected to the main to regulate the gas flow from the connecting tap, through the inner channelling towards the gas nozzles of the gas burners of the gas cooking appliance.
  • the opening has a circular section and, when the tap is installed in the main, the tap body of the gas tap surrounds the outer mouth of the opening, thereby sealing it.
  • this has a groove on its connecting wall.
  • the groove can be a blind crevice located near the opening mouth and projecting into the main.
  • the groove preferably extends longitudinally over the connecting wall of at least a part of the main, more preferably extends longitudinally over the entire connecting wall of the main.
  • a first body protrusion of the tap body of the tap gas can be connected to the groove, more preferably without any positive-fit tool.
  • the groove can have an L-shape into which the first body protrusion of the tap body can be hooked and, rotating on this, the gas tap being pulled down towards the main, the tap is connected in the gas outlet opening.
  • the main is made in one piece, preferably rigid and non-flexible, e.g. made from an extruded metal bar such as of aluminium, and the groove and/or the inner channelling are extruded together with the rest of the main.
  • the manufacturing of the main is simple and economical.
  • the main is made from a molten metal bar and the groove and/or the inner channelling are shaped in the main.
  • the main is made from a metal bar and that at least the groove and/or the inner channelling have been machined with a cutting tool.
  • the gas tap has at least a rib for a second body protrusion of the tap body of the gas tap to be connected to the same by means of a connecting element.
  • the rib extends longitudinally along the gas main.
  • the rib can be a projection out of the main or an outer wall of the main to which the second body protrusion of the gas body can be fixed.
  • the housing of the appliance is the outer frame of the gas cooking appliance inside which the remaining functional components are arranged and which is closed by the covering plate, the appliance interior space being thereby defined.
  • the main is arranged in the interior space and is usually fixed to the housing.
  • the housing is usually made of a metal sheet and the main is fixed, preferably screwed, to the housing.
  • the gas main has a main side wall extending on a plane and which is fixed to a substantially flat housing side wall of the housing. This is very advantageous since the shaping number required during the manufacturing of the housing is significantly reduced and, in this manner, the problems relating to tolerance chains when the components are installed in the appliance interior space are too.
  • the appliance interior space is defined by the housing and by the covering plate, which is fixed to the housing on the appliance, and/or can be the oven cavity.
  • a gas tap in the gas main from which a gas pipe extends capable of leading the gas flow from the connecting tap, through the inner channelling, flowing through the outlet opening, the gas tap and the gas pipe towards the nozzles of the cooking hobs.
  • the gas main has a main top wall extending on a plane and contacting a plate inner face of the covering plate.
  • the main further performs a structural function in such a manner that the top plate rests on the main giving bend resistance against bending that might occur in the covering plate when receiving a weight or force directed into the appliance.
  • That main top wall can be entirely flat or be formed by contact strips with the plate inner face, or a plurality of contact points with the plate inner face and, in all cases, it complies with the same reinforcing function of the covering plate.
