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.
Claims20
A stovetop burner assembly for use with a cookware vessel, the assembly including:
- a first non-inductive burner sub-assembly including a vessel support hardware set and a non-inductive burner hardware set;
- and
- a control module;
- wherein:
- the control module is operatively connected to the first non-inductive burner hardware set to control on/off status of the first non-inductive 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 electromagnetic signal to 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 non-inductive burner hardware set in a manner that is based, at least in part upon whether the cookware vessel is in contact with both of the two vessel receiving portions of the vessel support hardware set.
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.
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.
