Definitions

  • This invention relates to a cooking hob with gas burners in accordance with the introduction to the main claim.
  • Cooking hobs of the aforesaid type generally comprise a surface or hob plate (of metal, toughened glass or glass ceramic) in which several seats are provided for burners. These latter comprise a usual burner body provided advantageously with an igniter or flame generator and having a flame diffuser or flame spreader, on which a cap is placed. Each burner receives a gas flow regulated by an actuator controlling the burner operation. This actuator (generally of knob type) cooperates with a corresponding valve member associated with a pipe through which gas is fed to the hob.
  • This pipe is usually positioned on one side of the hob between the aforesaid hob plate and a lower plate associated with a support structure (which can be an appropriate self-supporting structure in a kitchen, or a cabinet if the hob is to be built-in).
  • a support structure which can be an appropriate self-supporting structure in a kitchen, or a cabinet if the hob is to be built-in.
  • said valve members which are sealedly associated in known manner with the said pipe. From these members there extend tubes terminating below the burner seats where connections are provided to the overlying burner.
  • US-A-2 185 275 discloses a gas cooking hob according to the preamble of the main claim, in which the pipe through which gas is fed to the hob is positioned centrally.
  • An object of the invention is to provide a gas hob representing an improvement on similar currently available hobs.
  • a particular object of the invention is to provide a hob of the stated type in which the number of components is small (less than in the case of known hobs), and with a shorter assembly time than known hobs.
  • a further object is to provide a hob of considerable safety.
  • FIG. 1 shows a cooking hob 1 comprising a surface or hob plate 2 of metal (for example bare or enamelled steel) having a plurality of seats 3 (four in Figure 1) for corresponding gas burners 4.
  • the seats 3 are positioned non-aligned along various edges (for example the front edge 5 and rear edge 6) of the hob plate 2.
  • a control panel 8 on which a plurality of actuators or knobs 9 are present for activating the flame and regulating the flame power of each burner 4.
  • Each burner comprises a burner body 10 acting as a diffuser and provided with a flame spreader 11 and a cap 12, a usual igniter or spark plug 13 and an injector 14.
  • An activator 9A for the spark plugs 13 may, if desired, be provided on the panel 8.
  • On the hob plate 2 there are provided one (as in Figure 1) or more grids 15, a lid or closure element 16 hinged in known manner to said hob by a suitable known hinge member 18 being advantageously closable onto said hob plate.
  • the hob plate 2 can be superposed, via a suitable gasket 22, on a (known) hollow structure 20 coupled to a support for the hob (such as a self-supporting structure, or to a kitchen cabinet if the hob is to be built-in).
  • a support for the hob such as a self-supporting structure, or to a kitchen cabinet if the hob is to be built-in.
  • said pipe 25 is a single pipe for all the burners 4 and is bent into a shape such that it lies below each seat 3 present in the hob plate 2, whatever the arrangement of the burners (and hence of the relative seats) on this latter.
  • the pipe is closed at one end 25A.
  • the pipe 25 is connected to a fixed gas main via a usual connection member 26, and has a plurality of apertures 27 (of number equal to the number of burners 4), to be positioned below the seats 3.
  • Valve members 28 connected to the injector 14 are sealedly arranged on these apertures and are controlled by respective actuators or knobs 9 via known remote operating means, such as a universal joint 29 (as shown in Figure 2), a flexible cable or the like connected to the knobs 9 in known manner.
  • Each valve member 28, provided with the necessary seals is coupled to the corresponding aperture 27 via a usual clamping member 30.
  • the valve member preferably comprises, connected to a spark generator 32 connected to the spark plug 13, a usual sensor 31 for sensing gas flow to the injector. By means of this sensor, the spark plug is automatically activated on commencement of gas feed to the burner. This is an alternative to the aforestated activator 9A.
  • each seat 3 is formed by pressing, with a shape such that it itself defines the support 35B for the body 10 of the corresponding burner 4.
  • the base 35 is provided with a small through hole 37 for receiving the injector 14, which is fixed on this base by a nut 38 or a similar element.
  • the body of the burner 10 is carried by a metal support 40 which has a pressed and drawn part provided with a base 42 similar to said base 35, and is coupled in a sealed manner (via an element 41) to the hob plate 2.
  • the support 40 is coupled to the toughened glass or glass ceramic hob plate 2 via an elastic element 43 positioned below the hob plate 2.
  • the support 40 can be an interacting part of the valve member 28.
  • the invention reduces the number of components of the hob, to provide a very safe product. This is achieved by the particular arrangement of the pipe 25, which supports the injectors directly below each seat 3 for a corresponding burner and the valve member 28 connected to each injector, and by the particular shape of the hob plate 2 which where possible acts as a support for the burner body 10.
