Definitions

  • the present invention relates to a heating cooktop system that is capable of ensuring safety of a cooking process in the absence of a user monitoring such process.
  • a heating cooker may operate based on the process of heating a ferromagnetic material by electromagnetic induction where eddy currents are to be induced and resistance provides heat dissipation within said ferromagnetic material, i.e. a cooking vessel in the form of a pot or pan.
  • a heating cooker may also be a conventional gas cooker, in which case the heat energy is transferred to the vessel by way of burning the gas under the vessel.
  • Cooking fires are reported as the major cause of home fires and injuries.
  • the leading cause of fires in the kitchen is unattended cooking, meaning that cooking fires can be avoided simply by continuous monitoring. Anything that can catch fire such as oven mitts, wooden utensils, food packaging, towels or curtains can pose safety risks in this respect.
  • one’s continuous presence in the kitchen to carry out and monitor the cooking process while frying, grilling, or broiling food may not always be possible on the part of users due to many practical reasons, such as for instance a mother may leave the food in oil on an electric range unattended for helping her baby crying out in his/her room.
  • WO2012150216 defines a cooking hob with a time-of-flight camera that is arranged under a glass-ceramic cover for the gesture-based control of the cooking hob.
  • the present invention provides a heating cooktop system that is capable of monitoring and determining certain stages of the cooking process, in response to which an associated safety measure is taken.
  • the present invention provides a heating cooktop system that is capable of ensuring safety of a cooking process in the absence of a user monitoring such process, as provided by the characterizing features defined in Claim 1.
  • Primary object of the present invention is therefore to provide a heating cooktop system ensuring safety of a cooking process in the absence of a user monitoring such process.
  • the present invention proposes a heating cooktop system having a heating cooktop with a plurality of individual cooking zones including electrical heaters, induction heaters or gas burners and a monitoring unit in the form of a video frame capturing device.
  • the monitoring unit has an image analyzing unit and remotely communicates with the heating cooktop.
  • the monitoring unit graphically process video frames of a preconfigured surface area delimited by a cooking vessel’s inner surface located on any of the cooking zones.
  • the monitoring unit compares captured video frames and images with pre-stored reference images both to determine presence of predefined hazard situations and to identify children approaching near the heating cooktop.
  • Real-time video stream of the cooking operation can be remotely viewed by users by way of browsing the IP address of the monitoring unit.
  • Fig. 1 demonstrates a general perspective representation of the heating cooktop system according to the present invention.
  • Fig. 2 demonstrates a general perspective representation of the heating cooktop system with a range hood accommodating a monitoring unit according to the present invention.
  • the present invention proposes a heating cooktop system (1) typically having a heating cooktop (2) with a plurality of individual cooking zones (6) including electrical heaters or gas burners and a monitoring unit (3) in the form of an image sequence capturing device, i.e. a video camera.
  • the monitoring unit (3) of the invention is preferably installed on an installation surface such as the rear wall (5) or the range hood (4) above the cooking areas. In both cases, the monitoring unit (3) can be configured to have an adequate direct vision angle so as to be capable of capturing any visual differentiation occurring in a cooking vessel on any one of the burners (6).
  • the monitoring unit (3) comprises an image analyzing unit in signal communication with a control unit controlling the cooking operation of the heating cooktop (2).
  • the image analyzing unit of the monitoring unit (3) serves to the purpose of graphically processing captured information directly associated with a preconfigured planar area substantially definable by a cooking vessel’s inner surface disposed on any of the cooking zones (6).
  • a visual differentiation that is discernible by the monitoring unit (3) includes for example visual transformation of boiling substances when bubble formations occur or production of smoke due to burning cooking oil. Therefore, overflowing of the boiling substance can be avoided as well as the moment at which a given oil starts to smoke, that is, its smoke point can be detected.
  • the image analysing unit processes captured images by comparing those with pre-stored reference images to establish whether one of the predefined hazard situations is to be acknowledged. If so, the monitoring unit (3) communicates with the control unit of the heating cooktop to take the necessary action, which is in most cases, turning off of a burner or an electrical heater in the cooking zone (6).
  • the range hood (4) when smoke presence is sensed, can be automatically turned on following the turning off of the associated burner(s) or electrical heater(s) in the cooking zone(s) (6).
  • the present invention ensures that both a hazard preventive action is taken by cutting off the heat supply and the unpleasant situation already occurred to a certain extent until such situation is sensed is dealt with by operating the range hood to suck up the smoke.
  • the monitoring unit (3) analyzes image sequence to identify presence of children in direct proximity of the heating cooktop (2) so as to be able to reach a control panel thereof. Presence of a nearby child can be acknowledged based on a plurality of algorithmic approaches such as determining the moving object discernible in a sequence of images and comparing the same with pre-stored reference images or tracking the object’s movements and determining the height thereof in reference to a known position in comparison thereto, such as for instance in reference to the position of the heating cooktop (2).
  • the monitoring unit (3) runs an algorithm to determine the height of a child within a certain distance range, whereupon, the child lock is engaged and the control panel with respective buttons and knobs is inoperable.
  • the heating cooktop system s (1) monitoring unit (3) is accessible from a remote location via a wireless communication network.
  • said monitoring unit (3) being connectible to communication network, real-time video frames of the cooking operation can be accessed remotely by means of a remote terminal such as a computer/smartphone by way of using an associated IP address.
  • voice commands can be used to interact with the heating cooktop system (1) such that pre-configured voice commands initiates assigned tasks.
  • the present invention also proposes a method for operating a heating cooktop system (1) with said heating cooktop system (1) having a heating cooktop (2) having a plurality of individual cooking zones (6) including electrical heaters or gas burners and a monitoring unit (3) that is in signal communication with a control unit controlling the cooking operation of the heating cooktop (2).
  • Said method comprises the steps of:
  • the present invention provides a heating cooktop system (1) that is capable of monitoring and determining certain stages of the cooking process associatable with serious hazard situations, in response to which a respective safety measure is immediately taken.
