Abstract

A stovetop assembly where on/off status of a burner is controlled, at least in part, based upon whether the body of a cookware vessel is: (i) placed on a burner to complete an electrical circuit (for example direct current conductive circuit) or magnetic circuit; or (ii) removed from the burner to break the electrical or magnetic circuit. Also, a control box with a tether line extending therefrom that controls on/off status of a burner based, at least in part, upon whether a clip at a distal end of the tether line is mechanically connected to a cookware vessel.

First claim

What is claimed is:

1 . A stovetop burner assembly for use with an electrically conductive cookware vessel, the assembly including:
a first burner sub-assembly including a vessel support hardware set and a burner hardware set; and a control module; wherein: the control module is operatively connected to the first burner hardware set to control on/off status of the first burner hardware set; the vessel support hardware set includes two vessel receiving portions located in a spaced apart relationship so that the cookware vessel contacts of the two vessel receiving portions when the cookware vessel is placed on the vessel support hardware set; the control module is structured, programmed and/or connected to provide an electrical potential across the two vessel receiving portions of the vessel support hardware set; and the control module is connected, structured and/or programmed to control the on/off status of the first burner hardware set in a manner that is based, at least in part upon whether the electrically conductive cookware vessel is in contact with both of the two vessel receiving portions of the vessel support hardware set to form an electrically conductive circuit across the two vessel receiving portions.

2 . The assembly of claim 1 wherein the control module is further connected, structured and/or programmed to provide a direct current type potential across the two vessel receiving portions.

3 . A stovetop burner control assembly for use with a cookware vessel and a stove including a first stovetop burner, the assembly including:
a control module is operatively connectable to the stove to control on/off status of the first stovetop burner; a clip sub-assembly structured to be detachably mechanically connectable to the cookware vessel; and an elongated, flexible tether line having a first end and a second end; wherein: the first end of the tether line is mechanically connected to the control module; the second end of the tether line is mechanically connected to the clip assembly; and the control module is connected, structured and/or programmed to control on/off status of the first stovetop burner based, at least in part, upon whether the clip member is detachably mechanically connected to the cookware vessel.

4 . The assembly of claim 3 wherein:
the clip member includes a capacitive sensor;
the tether line includes a first conductor having a first end and a second end;
the first end of the first conductor is connected to the control module;
the second end of the first conductor is connected to capacitive sensor of the clip sub-assembly;
the tether line further includes a first conductor having a first end and a second end;
the first end of the second conductor is connected to the control module;
the second end of the second conductor is connected to capacitive sensor of the clip sub-assembly; and
the first conductor, the second conductor, the control module and the capacitive sensor are structured, connected and/or programmed so that a signal through the first and/or second conductors will have: (i) a first signal status when the clip sub-assembly is detachably mechanically connected to the cookware vessel, and (ii) a second signal status when the clip sub-assembly is detached from the cookware vessel.

5 . The assembly of claim 3 further comprising a control box sized, shaped and adapted to be mechanically connected over a rotary control on the stove;
wherein:
the control module is included in the control box; and
the control box includes rotary actuation hardware to selectively rotate the rotary control on the stove under control of the control module.
