Definitions

  • the present invention relates to the field of domestic safety systems. More particularly, the invention relates to a system for controlling gas supply to a gas heater.
  • Gas heaters such as gas stoves and heating stoves, are presently very common.
  • the first gas stoves were developed in the 1820s, but only in the 1880s did this technology become a commercial success.
  • the first gas stoves were rather unwieldy, but soon the oven was integrated into the base and the size reduced to better fit in with standard kitchen furniture of the day.
  • producers started to enamel their gas stoves for easier cleaning.
  • a high- end gas stove called the AGA cooker was invented in 1922 by Swedish Nobel Prize winner Gustaf Dalen.
  • Gas heaters use Butane or Propane as their energy source. These gases are popular in use as "clean" and easy to use substances. On the other hand, if not properly used, these gases can be dangerous. One of the obstacles for a user of a gas heater is remembering to turn it off. For example, leaving a gas stove in operation beyond the required period may result in overcooking or burning food; undesirable, but not dangerous. However, leaving a gas heater unsupervised may result in accumulation of gas in the room, which may poison people present in the room.
  • the present invention is directed to a system for controlling gas supply to a gas heater (such as a gas stove, a heating stove, and so on), the system comprising:
  • an electric valve for blocking and unblocking a gas supplying pipe (14) to the gas heater
  • a control unit for controlling the operation of the electric valve
  • a timer for determining a delay in activation of the electric valve to block the gas supply
  • a remote-control unit (20), for providing, in a mobile manner, user interface for setting the timer; and a processing unit, for concentrating information from the timer, and activating the operation of blocking gas supply passage whenever the time of the timer runs out.
  • the system may further comprise a button (22) through which a user can arbitrarily set the blocking and unblocking operation.
  • the timer is an electronic button.
  • the timer is mechanical.
  • the processing unit activates the operation of blocking gas supply passage by sending an instruction thereof via RF signals, IR signals, and so on.
  • the user interface comprises means for displaying the remaining time of the timer, such as a display
  • the system may further comprise sound indication for operations performed by the system.
  • the gas supplying pipe supplies gas to the gas heater as an entirety.
  • the gas supplying pipe supplies gas to at least one flame unit of the gas heater.
  • One of the major advantages of the present invention is the fact that the system (for controlling gas supply to a gas heater) of the present invention can be installed in any existing gas heater, rather than requiring embedding in a special design at the gas heater manufacturer side.
  • the reasons for allowing installation of the system in an existing gas heater are ⁇ (a) since the user interface resides on a remote control unit, no modification to the existing gas is required; and (b) the blocking / unblocking mechanism does not interfere with the open / close mechanism already existing in the gas heater, but rather controls the pipe that provides gas to the heater.
  • the system for controlling gas supply to a gas heater of the present invention can be added to any existing gas heater, and therefore the user thereof need not buy a new gas heater in order to enjoy the advantages of the present invention.
  • Fig. 1 schematically illustrates a kitchen in which is installed a gas stove, according to one embodiment of the invention.
  • Fig. 2 schematically illustrates a system for blocking the gas supply to a gas stove, according to one embodiment of the invention.

  • a turned on flame unit 16 can be turned off in two ways: manually, as in the prior art, and by the remote -control unit.

  • control unit One way to turn off a heater is by blocking its gas supply, as illustrated in Fig. 2.
