Definitions

  • This invention relates to an automatic device for igniting appliances provided with gas rings, such as cooking stoves and cooking hobs.
  • the invention relates to those appliances provided with at least one gas ring with which a known feed tap is associated.
  • the tap can only be opened after axially pushing the corresponding operating knob against elastic means which oppose said knob.
  • the stem which operates the valve part for opening and closing the tap is associated with the body of the tap by a bayonet connection which prevents undesirable rotation of the stem when the tap is closed.
  • the main object of the present invention is to provide an automatic ignition unit which obviates the aforesaid within the context of a simple and rational construction.
  • the invention consists of associating with gas opening and closure taps a common member which is sensitive to the axial sliding of each individual tap, and which in its turn operates a common electrical operating operating member for the ignition means associated with each gas ring.
  • the device according to the invention comprises a common gas ring ignition control member which is hinged to the body of the cooking stove or cooking hob on an axis parallel to the line on which the taps lie, is disposed transversely to the sliding direction of the respective stems, and is coupled to each, of these latter in such a manner that engagement occurs in only one direction.
  • Said common ignition control member is made to rotate in one direction by the opening action of any one of said stems, and in the opposite direction by elastic repositioning means acting against the axial sliding of the stems.
  • a common control device is also provided by which all the gas ring ignition heads are energized and de-energized when the common control member is made to rotate by the axial movement of at least one of the tap stems.
  • Figure 1 is a partial perspective view of the invention associated with a cooking hob of the built-in type.
  • Figures 2 and 3 are sections on the lines II-II and III-III of Figures 1 and 2 respectively, to an enlarged scale.
  • Said figures show a cooking hob indicated overall by 1, comprising two superposed half-casings 2 and 3 respectively, these latter consisting of two punched and drawn metal sheets.
  • the cooking hob 1 is intended to be built into a working top or another equivalent such, as a kitchen unit is unimportant.
  • the upper half-casing 2 is provided with a sunken portion 20 for collecting liquids which spill for example during cooking, a series of gas rings 21 being associated with said sunken portion.
  • Each individual gas ring 21 is connected to a feed pipe 4 which branches from a front manifold 40 via a respective tap 5.
  • the manifold 40 and taps 5 are fixed to a common support 6 by a series of clamping devices 60 (see Figure 2), the operating stems 50 of said taps 5 extending above the upper half-casing and above an overlying masking plate 7 to receive the corresponding operating knobs 51.
  • each knob 51 there is provided a thrust ring 8, which is mounted on the respective stem 50 to lie between a shoulder on this latter and a circlip 9.
  • the fork-shaped elements 11 are formed integrally with an elongate member 12 which is positioned to the side of the taps 5 and is bent to form a double step when viewed in cross-section (see Figure 2).
  • the member 12 comprises at least two slots 13 ( Figures 1 and 3) which receive respective tongues 14, these latter having an end portion which can be bent to prevent withdrawal of the member 12 ( Figures 1 and 2).
  • This latter is associated with an ignition device 17, for example of piezoelectric type, which is connected to the ignition heads 22 provided immediately to the side of the gas rings 21.
  • the device 17 can be of the type which is operated either on pressing the pushbutton 16 or on releasing the pushbutton 16 after it has been pressed.
