Abstract

A system for detecting a possibility of boiling over and preventing said boiling over, the system comprising a vessel (101) having a lid (102), the lid (102) being characterised in that it is configured: to receive information on an initial level of a vessel content and a current level of the vessel content; and based on a difference between the initial level and the current level as well as the time of a creation of said difference: to instruct, by means of a controller (203), a height actuator (207) of the lid (102) to extend said lid (102) vertically, in order to extend the height of said vessel (101); and to instruct, by means of a controller (203), an aperture actuator (206) to create an aperture in a top of the lid (102) in order to facilitate exchange of heat.

First claim

The invention claimed is:

1. A system for detecting a possibility of boiling over and preventing said boiling over, the system comprising:
a vessel ( 101 ) having a set of sensors configured to detect an initial level of a vessel content and a current level of the vessel content; and
a lid ( 102 ) including a circuit, the circuit in the lid ( 102 ) being characterised in that it is configured:
to receive information, from the set of sensors on the initial level of the vessel content and the current level of the vessel content; and
based on a difference between the initial level and the current level determined by a controller of the circuit, as well as the time of a creation of said difference measured by a timer of the circuit:
to instruct, by means of the controller ( 203 ) of the circuit, a height actuator ( 207 ) of the circuit of the lid ( 102 ) to extend said lid ( 102 ) vertically, in order to extend the height of said vessel ( 101 ); and
to instruct, by means of the controller ( 203 ), an aperture actuator ( 206 ) of the circuit to create an aperture in a top of the lid ( 102 ) in order to facilitate exchange of heat.

2. The system according to claim 1 wherein said height actuator ( 207 ) extends said height of the lid ( 102 ) by means of a spring or an electric motor.

3. The system according to claim 1 wherein said aperture actuator ( 206 ) creates said aperture of the lid ( 102 ) by means of a spring or an electric motor.

4. The system according to claim 1 wherein said height actuator ( 207 ) comprises a release mechanism configured to extend a flange ( 1005 ) between a bottom portion ( 1100 ) of the lid ( 102 ) and the top portion of the lid ( 102 ).

5. The system according to claim 1 wherein a content level sensor ( 202 ), configured to provide said information on the level of the vessel content, is submersible in the vessel content and mounted on an extensible, multi-segment support ( 1104 ).

6. A method for detecting a possibility of boiling over and preventing said boiling over in a vessel ( 101 ) covered with a lid ( 102 ), said method being characterised in that it comprises the steps of:
detecting ( 301 ) an initial content level by a sensor ( 202 );
detecting ( 302 ) a current content level by the sensor ( 202 );
verifying ( 303 ) whether a predefined threshold has been met ( 303 ) between said initial content level and said current content level;
when said threshold has been met, invoking ( 306 ) a height actuator ( 207 ) of the lid ( 102 ) to extend said lid ( 102 ) vertically, in order to extend the height of said vessel ( 101 ).

7. The method according to claim 6 wherein after the level threshold condition has been met, the system executes a step of awaiting ( 304 ) a time threshold condition ( 304 ) between said initial and current content level.

8. The method according to claim 6 wherein the method further comprises the steps of:
waiting for a predefined threshold of time and verifying ( 307 ) whether the content level still rises and in case it does, invoking an aperture actuator ( 308 ) configured to create an aperture in a top of the lid ( 102 ) in order to facilitate exchange of heat;
awaiting ( 309 ) a content level decrease threshold condition to be met and in case it is met:
closing the aperture actuator ( 310 ), thereby closing said aperture; and
closing the height actuator ( 311 ), thereby decreasing said extended height of the lid ( 102 ).

9. A non-transitory computer readable medium storing computer-executable instructions performing all the steps of the computer-implemented method according to claim 6 when executed on a computer.
