Definitions

  • the present invention relates to a device for gas or electric cooking plates.
  • switch-off and indication systems for gas and electric cooking plates comprise systems with safeties which in case of accidental extinguishing of the flame (only for gas versions) block the delivery of gas and a timer which, when set to the end of the cooking time, activates only an acoustic warning.
  • the electric flame ignition part is separate with respect to the self extinguishing system.
  • the user must therefore remain in the vicinity of the plates, at such a distance as to be able to hear the acoustic warning issued by the timer, so that he/she can then turn the plates off manually.
  • the acoustic warning of such known types of plate cannot be heard, for example, by people with hearing problems, and this limits its field of use.
  • the aim of the present invention is to solve the above-mentioned problems, eliminating the drawbacks of the cited background art, by providing a device which, applied to gas or electric cooking plates, does not require the constant presence of the user during its use.
  • an object of the invention is to provide a device which allows to achieve the automatic shutdown and/or ignition of a gas or electric cooking plate at a chosen time without the need for direct intervention on the part of the user.
  • Another object is to provide a device which allows to modulate the flame at a chosen time without the direct intervention of the user.
  • Another object is to provide a device which is structurally simple and has low manufacturing costs.
  • a device for gas or electric cooking plates characterized in that it is constituted by a timer with one or more time settings which is adapted, when a set time elapses, to activate both an acoustic warning and an interruption/limitation of the gas and/or electric power supply.
  • the reference numeral 1 designates a device for gas or electric cooking plates.
  • the device 1 comprises a timer 2 with one or more time settings, which is adapted, when a set time elapses, both to activate an acoustic warning, by means of an appropriate acoustic indicator 3, and to perform an interruption/limitation of the gas and/or, by opening an electrical contact, of the electric power supply of the plates.
  • the device 1 comprises a valve 4, or valve block 4, for controlling the flow of the gas for supplying the entire cooking range or each individual burner, both of which are not shown in the accompanying figures.
  • valve 4 or valve block 4 is operated by the timer 2, which can be programmed by means of a control panel 5 which is mounted for example flush with the cooking range, which is not shown in the accompanying figures, and includes a display 6 and buttons 7 for setting the self-shutdown time or times.
  • control panel 5 can be connected to the timer 2 by means of a wired or wireless remote link.
  • valves 4 depending on the embodiment of the device, can be of the on/off type, or can allow to modulate the flow of gas or reduce below the minimum value the gas in order to extinguish the flame.
  • valves 4 can be of the magnetic-drive type, so as to allow to achieve separation between the control device and a butterfly element 11, so as to ensure the tightness of the gas valve 4 without the use of gaskets, which over time can deteriorate.
  • the valve 4 comprises a gearmotor 8, on the axis of which a first magnet 9 is fitted which, coupled to a second magnet 10 arranged inside the valve 4 and fixed to the butterfly element 11, moves the valve into the position of the first magnet.
  • a magnetic position sensor 12 for example of the reed or Hall-effect type, is further present on the gearmotor 8 and allows the control to detect the position in which the valve 4 is closed.
  • the butterfly element 11 is supported by two bushes 13a and 13b, which are inserted within a tube or body 14 of the valve 4 and are sealed in order to avoid gas leaks.
  • the valve 4 is an integral part of the device 1, since it is controlled by the timer 2 with a dedicated control.
  • the valve 4, of the magnetic-drive type is very cheap to manufacture and, by means of a rotation time measurement method, allows to obtain the gas flow rate modulation function; such rotation time measurement method consists in measuring the time taken by the gearmotor 8 to make a full turn and then, starting from the closed position, activating for a fraction of the rotation time that corresponds to the chosen opening of the butterfly element 11.
  • valve 4 with a flat part, is designed specifically in order to minimize the air gap between the first and second magnets, so as to achieve the maximum mutual attraction force.
  • the tube or body 14 of the valve 4 and the butterfly element 11 must not be made of ferromagnetic material.
  • the gearmotor 8 for economic reasons, does not reverse its motion, but regulates or closes always by turning in the same direction, having over its entire rotation two open valve positions, two closed valve positions, and four adjustment positions.
  • the cooking range is provided with additional capillary safety valves, not shown in the accompanying figures, which are integrated in the gas cocks, also not shown.
  • the device 1 can comprise means for automatic and programmable electric ignition/limitation of the flame, which are constituted advantageously by an igniter 15, which is activated by an external command which arrives from a button or contact 16, which can be independent or integrated on the gas adjustment knobs; the igniter 15 is provided with an outlet for one or more ignition electrodes 17 which are arranged in the vicinity of the burners, which are not shown in the accompanying figures.
  • the device 1 may further comprise advantageously automatic means for the activation/deactivation of an extractor hood, designated schematically by the reference numeral 18, which are connected to the timer 2.
  • the device 1 according to the invention in the embodiment for gas cooking plates, may provide the general gas control with shutdown of all the burners when the time expires, the integrated igniter 15, the acoustic warning, and optionally the hood control.
  • the device 1 can advantageously provide for the separate control of each individual burner when the time expires, the integrated igniter 15, the acoustic warning and optionally the hood control.
  • the device 1 may provide alternately the separate control of each individual burner with throttling of the gas line when the time expires and the use of the capillary safety valve of the cooking range (which already exists) to close the gas, the integrated igniter 15, the acoustic warning and optionally the hood control.
  • the device 1 can provide for the separate control of each individual burner, with reduction of the flame to a minimum value and subsequent extinguishing thereof after an additional delay when the time expires, the integrated igniter 15, the acoustic warning and optionally the hood control.
  • the device 1 may provide for control of the individual plates when the time expires, the acoustic warning and optionally the hood control.
  • the timer 2 which has one or more time settings, when the set time expires, activates an acoustic warning and further, if it is not blocked by the user, in the case of gas cooking plates it turns off and/or reduces the flame by means of the valve or valves 4 or, in the case of electric cooking plates, closes or reduces the power or opens a contact, interrupting the supply of power to said electrical plates after a set time.
  • the action of the device 1 can be general, and can therefore shut down and/or reduce all the flames or plates when the time expires, or be selective and can therefore extinguish/reduce the individual flame or plate selected during the setting of the timer 2 with one or more timings.
  • the device 1 also comprises the means for the automatic activation/deactivation of an extractor hood
  • the hood can be activated or deactivated automatically and programmably by the timer 2.
  • the user can program the ignition and/or adjustment of the extent thereof.
  • the invention has achieved the intended aim and objects, a device having been provided for gas or electric cooking plates which allows to achieve an increase in safety, since the user sets the timer or timers which interrupt or reduce automatically the cooking, with the consequent reduction of the risk of fire or damage to the pots if they are left on the burner or on the plate.
  • the device according to the invention therefore allows to achieve an improvement in the quality of life, since it is no longer necessary to monitor cooking constantly, because the timer interrupts it autonomously and/or adjusts the flame when the time expires.
  • the device according to the invention allows to optimize costs and space occupation, since it comprises, on a single component which can be inserted directly into the cooking range, without the need for additional compartments, all of the devices needed to achieve the described functions.
  • the production costs of the heating element according to the invention remain low, since it is provided only by means of components which are easy to manufacture and/or assemble.
