Abstract
A cooktop appliance is generally provided herein. The cooktop appliance may include a cooktop panel, an electric heating element, a ferromagnetic tab, and a magnetic temperature switch. The electric heating element may be positioned at the cooktop panel. The electric heating element may include a first terminal and a second terminal. The ferromagnetic tab may be in thermal engagement with the electric heating element. The magnetic temperature switch may be positioned in selective magnetic engagement with the ferromagnetic tab. The magnetic temperature switch may be electrically connected in series with the second terminal and operable to restrict a voltage to the electric heating element above a predetermined temperature.
Claims17
A cooktop appliance comprising:
- a cooktop panel;
- an electric heating element positioned at the cooktop panel, the electric heating element including a first terminal and a second terminal;
- a ferromagnetic tab in stationary, conductive, thermal engagement with the electric heating element;
- and
- a magnetic temperature switch positioned in selective magnetic engagement with the ferromagnetic tab, the magnetic temperature switch being electrically connected in series with the second terminal and operable to restrict a voltage to the electric heating element above a predetermined temperature,
- wherein the magnetic switch comprises a retainer bracket disposed below the ferromagnetic tab, a switch body mounted to the retainer bracket, a magnetic element housed within the switch body radially outward from the retainer bracket, an articulating connection plate fixed to the magnetic element within the switch body, and a mechanical spring motivating the connection plate and magnetic element radially outward away from the ferromagnetic tab, and
- wherein the ferromagnetic tab is positioned below the heating element and received within the retainer bracket.
A cooktop appliance comprising:
- a cooktop panel;
- an electric heating element positioned at the cooktop panel;
- an element frame supporting the electric heating element, the element frame being positioned below the electric heating element;
- a ferromagnetic tab extending from the element frame in stationary, conductive, thermal engagement with the electric heating element;
- and
- a magnetic temperature switch positioned in selective magnetic engagement with the ferromagnetic tab, the magnetic temperature switch being operable to restrict a voltage to the electric heating element above a predetermined temperature,
- wherein the magnetic switch comprises a retainer bracket disposed below the ferromagnetic tab, a switch body mounted to the retainer bracket, a magnetic element housed within the switch body radially outward from the retainer bracket, an articulating connection plate fixed to the magnetic element within the switch body, and a mechanical spring motivating the connection plate and magnetic element radially outward away from the ferromagnetic tab, and
- wherein the ferromagnetic tab is positioned below the heating element and received within the retainer bracket.
