Safety stop device with automatic safety valve for cookers, ovens and gas boilers |
(57) The principle of working of this invention is based on the possibility of a specific
turning off device or electric- valve that is able to stop automatically and after
a certain period of time (programmed by the user ), when the presence of a person
is not noticed by a specific sensor or detector.
In this way there's the turning off of the ovens or cookers in case the user forgot
to turn them off before going out from the house, avoiding any damage or fire.

[0001] The principle of working of this invention is based on the possibility of a specific
turning off device or electric- valve that is able to stop automatically and after
a certain period of time (programmed by the user ), when the presence of a person
is not noticed by a specific sensor or detector.
[0002] In this way there's the turning off of the ovens or cookers in case the user forgot
to turn them off before going out from the house, avoiding any damage or fire.
Description
[0003] As it is exemplified in the electric diagram, there's a sensor that is put nearby
the cooker so that it can detect the presence of a person in movement; a signal is
sent to a switchboard that keeps the valve open letting gas pass through the tube.
[0004] On the contrary, when a sensor remains inactive for a certain period of time (programmed
by the user in the switchboard) because nobody is passing by, the safety valve closes
automatically and no gas can pass.
[0005] The principal of working of the invention is based on the possibility that a specific
electro-valve can close automatically and after a certain period of time( programmed
by the user).
[0006] When a special sensor doesn't notice the presence of a person in movement; in this
case the cooker or oven or both turns off automatically since it means that the user
forgot to turn it off before going out from the house or from that place, avoiding
in this way, damages or fire.
[0007] As it is exemplified in the electric diagram, a sensor is put nearby the cooker;
when it detects the presence of a body in movement, a signal goes to a special switchboard
that keeps the valve open ;
[0008] On the contrary, when a sensor remains inactive for a certain period of time (programmed
in the switchboard by the user), that is when nobody moves in that area, the safety
valve closes automatically and no gas can pass.
1. Safety system for places in which there are appliances that work through gas-burning
for domestic uses and particularly for cookers, ovens and gas boilers.
2. Safety system usable in any places also different from the domestic ones.
3. Electronic and automatic safety stop device that is working after a certain period
of time ( programmed by the user) when nobody is in that area.
4. Exclusive use of a timer to regulate the time.
5. Activity of a sensor able to detect the presence of people in that area.
6. Automatic turning off device of the gas through an electro-valve inserted in the tube
of alimentation.
