Abstract

A switch assembly for controlling the ignition of gas burners of a cooking appliance having one or more gas valves. The switch assembly includes at least one first support member, operably couplable to a first gas valve, a spring biased ignition switch operably mountable to the at least one first support member, and an actuating member, having a longitudinal axis and operably couplable to at least the first gas valve between the at least one first support member and at least a control knob of at least the first gas valve. The actuating member is adapted to move between a first position, actuatingly engaged with the ignition switch, and a second position, actuatingly disengaged from the ignition switch, wherein the actuating member is moved towards the first position by at least the control knob, and back towards the second position by the spring biased ignition switch.

First claim

What is claimed is:

1. A switch assembly for controlling the ignition of gas burners of a cooking appliance having one or more gas valves, comprising:
at least one first support member, operably couplable to a first gas valve;
a spring biased ignition switch, operably mountable to the at least one first support member;
an actuating member, having a longitudinal axis and operably couplable to at least the first gas valve between the at least one first support member and at least a control knob of at least the first gas valve, adapted to move between a first position, actuatingly engaged with the ignition switch, and a second position, actuatingly disengaged from the ignition switch, wherein the actuating member is moved towards the first position by at least the control knob, and back towards the second position by the spring biased ignition switch; and
a cam mechanism adapted to operably engage, at a predetermined minimum angle of rotation and translation of the control knob, with at least one aperture of a plurality of apertures spaced apart along the longitudinal axis.

2. A switch assembly according to claim 1 , wherein, when the cooking appliance has a plurality of serially arranged gas valves, the actuating member is operably couplable to all of the plurality of gas valves along the longitudinal axis.

3. A switch assembly according to claim 2 , wherein the actuating member comprises the plurality of apertures, each aperture configured to operably engage with a respective one of the plurality of gas valves, during use.

4. A switch assembly according to claim 1 , wherein the actuating member is operably couplable to at least the first gas valve via the cam mechanism adapted to convert a rotationally translational movement of the control knob of at least the first gas valve into a linear movement of the actuating member between the first position and the second position along the longitudinal axis.

5. A switch assembly according to claim 1 , wherein the at least one first support member comprises a switch bracket configured to mountingly receive the spring biased ignition switch.

6. A switch assembly according to claim 1 , wherein, when the cooking appliance has a plurality of serially arranged gas valves, the actuating member is movable towards the first position at least by the control knob of any one of the plurality of serially arranged gas valves.

7. A switch assembly according to claim 1 , when the cooking appliance has a plurality of serially arranged gas valves, comprising at least one second support member operably couplable to a second gas valve.

8. A switch assembly according to claim 7 , wherein the actuating member is movably coupled to the first and second support member.

9. A switch assembly according to claim 8 , wherein each one of the first and second support member is adapted to slidingly retain a respective end portion of the actuating member.

10. A switch assembly according to claim 1 , wherein the actuating member is pivotably coupled to at least the first support member and configured to rotatably move between the first position and the second position about a pivot axis that is parallel to the longitudinal axis.

11. A switch assembly according to claim 10 , wherein the actuating member is pivotably coupled to the first support member and a second support member.

12. A cooking appliance comprising a switch assembly according to claim 1 .

13. A switch assembly for controlling the ignition of gas burners of a cooking appliance having one or more gas valves, comprising:
at least one first support member, operably couplable to a first gas valve;
a spring biased ignition switch, operably mountable to the at least one first support member;
an actuating member, having a longitudinal axis and operably couplable to at least the first gas valve between the at least one first support member and at least a control knob of at least the first gas valve, adapted to move between a first position, actuatingly engaged with the ignition switch, and a second position, actuatingly disengaged from the ignition switch, wherein the actuating member is moved towards the first position by at least the control knob, and back towards the second position by the spring biased ignition switch;
wherein the actuating member is operably couplable to at least the first gas valve via a cam mechanism adapted to convert a rotationally translational movement of the control knob of at least the first gas valve into a linear movement of the actuating member between the first position and the second position along the longitudinal axis, and wherein the cam mechanism is adapted to operably engage with at least a first one of a plurality of apertures at a predetermined minimum angle of rotation and translation of the control knob.

14. A switch assembly for controlling the ignition of gas burners of a cooking appliance having one or more gas valves, comprising:
at least one first support member, operably couplable to a first gas valve;
a spring biased ignition switch, operably mountable to the at least one first support member;
an actuating member, having a longitudinal axis and operably couplable to at least the first gas valve between the at least one first support member and at least a control knob of at least the first gas valve, adapted to move between a first position, actuatingly engaged with the ignition switch, and a second position, actuatingly disengaged from the ignition switch, wherein the actuating member is moved towards the first position by at least the control knob, and back towards the second position by the spring biased ignition switch, wherein the cooking appliance has a plurality of serially arranged gas valves, comprising at least one second support member operably couplable to a second gas valve;
wherein the actuating member is movably coupled to the first and second support member, and wherein each one of the first and second support member is adapted to slidingly retain a respective end portion of the actuating member.
