Definitions

  • the invention relates to an ignition actuator for gas cooking appliances according to the Preamble of claim 1.
  • An ignition actuating device of this type is known from EP 0 718 745 A2.
  • the object of the invention is to achieve the ignition actuation device in this way train them with no or no significant changes to gas cookers that have only one gas burner, and for gas cookers that have two or more gas burners, can be used and easily in existing constructions of Gas cookers can be installed without having to change them significantly.
  • the invention requires only one overall for one or more gas burners electrical switch.
  • a so-called microswitch is preferably used.
  • the mechanical structure is simple and enables safe operation of both or more gas taps as well as one or more ignition devices.
  • the ignition actuation device according to the invention is simple and inexpensive and can have large manufacturing tolerances.
  • a switching plunger used according to the invention can after switching the switch be moved past the switch by a switch cam on the switch plunger and thereby record a remaining switching path, which the operating device (Gag and shift linkage) is required in order to functionally secure the gas tap in question actuate. Because the switching plunger for actuating the electrical switch is not runs against an end stop, the actuating device is in its stroke movement not limited until she has fully operated the tap. This is very important because safe activation of the gas burning points or their gas burners, the tap stroke is fully utilized must become.
  • the ignition actuator shown in Fig. 1 according to the invention is for gas cooking devices such as gas hobs and gas stoves that have one or more gas burners and at each gas burner a gas burner, a gas tap and an ignition device for the gas burner.
  • Fig. 3 shows schematically four gas burning points of a gas well 2.
  • Each gas burning point has a tap 4, 5, 6 or 7 with a shaft 10, which are each one of the number of taps 4, 5, 6, 7 corresponding number of openings 12 with radial clearance extends therethrough in a rail-like at least one-armed lever 14 are formed, which can be tilted about an axis of rotation 20 in tilt bearings 16 and 18 above the tap shafts 10 (or below the tap shafts 10) transversely to them in the longitudinal direction of the rail extends.
  • the tilting bearings 16 and 18 are arranged in a stationary manner with respect to the gas trough 2.
  • FIG. 3 shows schematically and in a reduced form the gas cocks 4, 5, 6 and 7 Gas-supplied gas burners 24, 25, 26 and 27 and one for igniting their gas serving ignition device 30, 31, 32 and 33.
  • an electrical switch 36 preferably one Microswitch
  • electrical circuit 38 which is schematically only by a dashed line is shown connected to the igniters 30 to 33 around them to operate. This means that all igniters are from the same switch 36 switched on and off at the same time, but only the gas burner 24, 25, 26 or 27 is ignited, which is supplied by the tap 4, 5, 6 or 7 with gas. This is much cheaper and takes up less space in the gas cooker than one embodiment, in which as many switches as ignition devices are used.
  • the switch 36 can be switched by the lever 14 via a switching plunger 40, as is the case with this will be described below with reference to FIG. 1.
  • a receiving body 42 For each tap shaft 10, a receiving body 42 is provided, which on the of the Tap 4 to 7 opposite side of the lever 14 on the end portions of the tap shafts 10 plugged end and an end facing away from it, with which an actuating linkage 44 which e.g. is telescopic, is rotatably connected.
  • the Actuating linkage 44 is from a toggle arranged in front of an operating panel 46 48 rotates to open and close the associated gas tap 4 to 7.
  • By manual Pushing in the toggle 48 becomes the actuating linkage 44, the receiving body 42 and the faucet shaft 10 axially pushed inward, thereby to the igniter 42 to an ignition spark for igniting the gas of the gas burner in question 24 to 27 produce.
  • the axial movement of the toggle 48 is not directly on the ignition devices 32 transferred, but the receiving body 42 is from the toggle 48 against the lever 14 pressed and pivots it about its axis of rotation 20.
  • the lever 14 presses here the plunger 40 against the force of a compression spring 50 away, the movement of the Tappet 40 actuates the switch 36, which in turn via the electrical circuit 38 Firing devices 30 to 33 actuated so that they generate an ignition spark (or Bring glow wire to glow) to ignite the gas of the gas burner in question.
  • each of the taps 4, 5, 6 and 7, the parts assigned to them form gags 48, rods 44 and receiving body 42 an operating device.
  • an operating device for each of the cocks 4, 5, 6 and 7 is such an operating device on the side facing away from the taps 4 to 7 Lever 14 arranged and the plunger 40, the switch 36 are on the same side of the Lever 14 arranged like the gas taps 4 to 7, i.e. on the back of the lever 14.
  • the rods 44 are arranged approximately parallel to the plunger 40, each in the tangential direction to the axis of rotation 20 at the same lever arm distance L1 from this axis of rotation 20.
  • This lever arm distance L1 on which the middle line of force 52 of each of the linkages 44 can be pressed against the front side 54 of the lever 14 via the receiving body 42, can be greater than or equal to or preferably smaller than the lever arm distance L2 be with which the plunger 40 on its middle line of action 58 against the back 56 of the lever 14 presses.
  • a short pressure actuation distance S1 of the Toggle 48 perpendicular to its plane of rotation in a larger actuation distance S2 of the plunger 40 converted.
  • the plunger 40 lies on the back 56 and the pressure piece 42 rests with a pressure surface 60 on the front side 54 of the lever 14.
  • the plunger 40 is supported by a spring means, e.g. a compression spring 62 against the lever 14 and biased against the receiving body 42 so that the entire actuator is rattle-free.
  • the compression spring 62 is supported in the longitudinal direction of the ram on the one hand on a tappet ring collar 63 and on the other hand on the switch 36 or on a switch carrier 64 in the longitudinal direction of the plunger.
  • the movement of the ram 40 in the direction of the lever 14 is limited, if provided on the tappet 40, to the front showing stop surfaces 65 on a rear surface 69 of the switch carrier 64 (or the Switch 36).
  • the plunger 40 is guided in the switch carrier 64 in the longitudinal direction of the plunger, preferably via Bearing points 66 and 67, via which the tappet can tilt in the tappet transverse direction or
  • the plunger 40 has a transverse to the longitudinal direction of the plunger, z. B. upward, cam surface 70, on which an actuating element 72 of the switch 36 runs and is pushed away into the switch for switching this switch 36 and thus also for switching on the ignition devices 30 to 33 via the electrical circuit 38 when one of the toggles 48 is pressed manually and thereby the receiving body 42 belonging to it presses with its pressure surface 60 against the front of the lever 14 and pivots it about its axis of rotation 20, whereby the lever 14 moves the plunger 40 in the longitudinal direction of the plunger and its cam surface 70 the switching element 72 of the switch 36 operated. If the manual pushing force on the toggle 48 is then no longer present, the compression spring 62 pushes the plunger 40 back into the starting position shown in FIG.
  • the plunger 40 also moves the receiving body 42 and the linkage 44 of the previously pressed toggle 48 together with this toggle 48 back into the starting position via the lever 14.
  • the receiving body 42 can only press against the front 54 of the lever 14 and otherwise have no connection with the lever 14.
  • the tap shafts 10 also have no connection with the lever 14, but extend through the openings 12 without any force acting on the lever when a knob 48 is pressed, the other gags in question are not moved by the lever arm 14, but the lever 14 is lifted in the circumferential direction about the axis of rotation 20 by the receiving bodies 42 of the other, not actuated gags 48.
  • the plunger 40 preferably has a star shape in cross section, as shown in FIGS and 2 can be seen. Its lower longitudinal rib 80 thus formed is between two lower ones Bearing points 66 can be passed in the ram longitudinal direction. His two from each other protruding lateral ribs 82 and 84 are each between a lower bearing point 66 and an upper bearing point 67. A cutout or, according to FIG. 1, an oblique or arcuate end portion of the upper rib 88 forms the cam surface 70 thereof Ram 40.
  • the lever 14 could also have two arms be formed and the linkage 44 via a receiving body 42 on a lever arm and engage the plunger 40 on the other lever arm.
  • the operating device 42, 44, 48, the Tappet 40 and the switch 36 may be arranged on the same side 54 of the lever 14.
