Abstract

A system for detecting a possibility of boiling over and preventing said boiling over comprising a vessel having a vessel's lid, the lid being characterised in that it is configured to: receive information on an initial level of the vessel's content and current level of the vessel's content; and establish on which heating section of a particular cooktop the vessel and the lid are positioned; and based on a difference between the initial level and the current level as well as the time of the creation of said difference: the lid is configured to instruct a height actuator of the lid to extend said lid vertically, in order to extend height of said vessel, and the lid is configured to instruct an aperture actuator to create an aperture in the lid's; the lid is configured to communicate with said cooktop in order to decrease power generation on said heating section.

First claim

The invention claimed is:

1. A system for detecting a possibility of boiling over, and preventing said boiling over, of contents in a vessel having a lid, the lid having an adjustable aperture and being height-adjustable relative to the vessel, the system comprising:
a height actuator configured to adjust the height of the lid relative to the vessel;
an aperture actuator configured to create the aperture, and to adjust a size thereof;
one or more sensors configured to detect a level of said contents; and
a controller communicatively coupled to each of the one or more sensors, height actuator and aperture actuator,
wherein the controller is configured to:
a) receive information from the one or more sensors on an initial level of said contents and current level of the said contents;
b) determine a difference between the initial level and the current level; and
c) based on said difference, take one or more of the following actions:
(i) instruct said height actuator to extend said lid vertically, thereby raising the height of said lid relative to said vessel;
(ii) instruct said aperture actuator to open said aperture thereby facilitating an exchange of heat;
(iii) communicate with a cooktop on which the vessel is situated in order to decrease power generation of a particular heating section of said cooktop on which the vessel is situated.

2. The system according to claim 1 , wherein said height actuator adjusts said height of the lid by means of a spring or an electric motor.

3. The system according to claim 1 , wherein said aperture actuator creates said aperture by means of a spring or an electric motor.

4. The system according to claim 1 , wherein said height actuator comprises a release mechanism configured to extend a flange between a bottom portion and a top portion of said.

5. The system according to claim 1 , wherein said one or more sensors is submersible in said content and mounted on an extensible, multi-segment support.

6. The system according to claim 1 , wherein the action of communicating with a cooktop further comprises establishing, via a proximity identification circuit within said lid, the particular heating section.

7. The system according to claim 1 , wherein said controller is configured to communicate via a communication module with a mobile device in order to report to the mobile device, information regarding whether a boiling over situation has been prevented or not.

8. The system according to claim 7 , wherein said communication module operated according to the Bluetooth or ZigBee protocol.
