Definitions

• the present invention relates to a cooking device comprising a gas control knob having ignition function.
• the gas flow control knob in a gas appliance also activates the igniter switch.
• the igniter switch When the knob is depressed from a predetermined distance, the igniter switch is turned on to initiate a sparking operation.
• the igniter switch is preferably constituted by a multi-piece outer casing within which is mounted multiple igniter contacts, and when the knob is depressed, multiple igniter contacts activated together with an activating member contact the terminal ends having a biased structure transmitting signals to the igniter unit for initiating ignition.
• the aim of the present invention is the realization of a cooking device comprising a knob having a simple structure that is operated to start ignition by pressing on any time during the rotation of the knob.
• gas flow is provided from a gas valve to the gas burners situated on the cook-top and an ignition unit provides the ignition of the gas burners within the structure of the cooking device.
• the ignition unit is activated by the gas control knob.
• the knob activates ignition, serving as a switch by means of an activator pin that is affected by axial movement.

• the cooking device (1) comprises a gas valve (2) that provides gas flow to the gas burners on the cook-top, a knob (3) providing the gas valve (2) to open and close for adjusting the desired amount of gas flow and serving as an ignitor switch by the user's pushing motion, a panel (4) on which the knob (3) is situated, an ignition unit (5) that starts the ignition process as the knob (3) is pushed serving as an ignitor switch, one or more cables (6) that provide the electrical connection of the knob (3) and the ignition unit (5) and allowing the positioning of the ignition unit (5) anywhere separate from the knob (3), and one or more spark plugs (7) that generate a spark that ignites the gas burners with the signal received from the ignition unit (5).
• the knob (3) comprises a handle (8) activated by the user, a frame (9) fixed to the panel (4), inside which the handle (8) moves, on which the knob (3) functions are marked, a transmission means (25) that serves to transmit the rotational and/or the pushing movement of the handle (8), and a knob casing (15) fixed to the panel (4), housing the transmission means (25).
• the transmission means (25) comprises a pusher (10) connected to the handle (8) that starts ignition when it makes an axial movement and a coupling (11) that allows its movements in the radial and axial directions, a shaft retainer (12) inside which the gas valve (2) shaft is seated and activated by the coupling (11), a spring (13) on which the shaft retainer (12) is seated and a housing ring (14) on which the spring (13) is seated allowing the rotational movement.
• the knob (3) comprises one or more terminals (18) to which the cables are connected and fixed to the knob casing (15), one or more conductive tips (19) that provide the connection of the terminals (18) within the knob casing (15) and an activator pin (16) that provides the electrical connection between the conductive tips (19), fixed to the rear wall of the knob casing (15), positioned between the transmission means (25) and the rear wall of the knob casing (15) without being connected to the transmission means (25), pushed in the axial direction by the transmission means (25), being affected by only the pushing movement of the transmission means (25) in the axial direction without being affected by its rotational movement.
• the activator pin (16) is activated by the contact of the pusher (10) situated in the transmission means (25).
• the knob casing (15) comprises a hole (23) to which the activator pin (16) is fitted, with one end of the activator pin (16) extending out allowing its free movement in the axial direction.
• the activator pin (16) comprises a body (17) that moves by means of the pushing applied via the contact of the transmission means (25), one or more contact extensions (20) connected on the body (17) that contact the conductive tips (19) by the movement of the body (17) in the axial direction, a contact spring (21) positioned between the contact extension (20) and the knob casing (15) so as to surround the body (17), a pusher spring (22) situated on the contact extensions (20) so as to surround the body (17), and one or more notches (24) that prevent its end extending out from the hole (23) to enter into the knob casing (15).
• the knob (3) is opened by rotating the handle (8) on the knob (3) connected to the respective gas burner and the handle (8) is pushed at any moment during the rotational movement providing the knob (3) to serve as an ignition switch by means of the contact of the conductive tips (19) with the contact extension (20). Regardless of the position of the handle (8) in the rotational direction, after enough pushing force is applied to overcome the contact spring (21), the conductive tips (19) stay in contact with the contact extension (20) and ignition continues during contact.
• the knob (3) serves as an ignition switch by being pushed from the handle (8), the ignition unit (5) is activated by means of the cables (6) and the generated signal provides the spark plug (7) to ignite the gas burner.
