A universally applicable regulation function is provided for a gas-operated heating device with more than one burner. The function facilitates start-up, regulation, and deactivation processes. A first valve and a second valve are connected together in a gas-tight manner. The first valve has an ignition lock which closes the main gas flow in the event of an ignition, a thermoelectric ignition fuse, a thermostat, and optionally an integrated pressure regulator. The start-up of the first valve allows the activation and deactivation of the gas flow. The first valve has two gas outlets, a first outlet for connecting the second valve, wherein the first outlet is located downstream of the ignition fuse and the optional pressure regulator and upstream of the thermostat, and a second outlet downstream of the thermostat, the second outlet leading to a first burner. The second valve is a thermostat. The first outlet of the first valve is connected to the inlet of the second valve, and the outlet of the second valve is connected to a second burner.

An igniter assembly for a gas cooking appliance is disclosed herein. In some embodiments, the igniter assembly may have an igniter that can be removed from and/or inserted into an igniter socket through a surface of a cooking appliance without having to remove the surface of the cooking appliance. Accordingly, when the surface is being cleaned after cooking applications, the igniter can be removed from the surface, thereby eliminating any potential damage to the igniter and allowing the surface to be thoroughly cleaned. After cleaning, the igniter can then be re-inserted into the igniter socket through the surface of the cooking appliance without having to remove the surface of the cooking appliance.

Hot surface igniter assemblies used in cooktops are shown and described. The hot surface igniters include a silicon nitride ceramic body with an embedded, resistive, heat-generating circuit. The igniters are less than 0.04 inches thick, and when energized, they reach surface temperatures in excess of 2000° F. in under 4 seconds to ignite combustible gas such as propane, butane, or natural gas. Examples of cook top burner systems are also provided which allow the igniter to remain on after ignition at a power level that is lower than during ignition but high enough to ignite the cooking gas should a flame out occur. Examples are also provided of burners that ignite on a low flow setting (e.g., simmer) as opposed the high flow settings that are common in cook top industry.

A burner system for a cooking device has at least one burner surface wherein the at least one burner surface is designed in such a way that the burner system has a low minimum power density with homogeneous temperature distribution at the same time. In a first aspect, the burner system includes a fuel supply and a first burner surface for burning the fuel that is provided downstream of the fuel supply. The burner system includes a second burner surface for afterburning that is separate from the first burner surface and is provided downstream from the first burner surface. Moreover, a method for operating the burner system is shown.

A knob assembly includes a front panel, a knob located at a front side of the front panel and configured to rotate based on operation by a user, a knob shaft that is coupled to the knob and that extends through the front panel, a supporting pipe that receives the knob shaft and that supports the knob shaft, the supporting pipe being configured to maintain a position relative to the front panel, a valve configured to control supply of gas to the appliance, a valve shaft connected to the valve and configured to control the valve to adjust a flow rate of gas based on rotation of the valve shaft, and a joint that couples the knob shaft to the valve shaft and that is configured to transfer at least one of a rotational motion or a linear motion of the knob shaft to the valve shaft.

Cooktop appliances are provided. A cooktop appliance can include a gas burner; a manifold having a gas input; a primary line extending between the manifold and the gas burner, wherein the primary line operates as a non-modulated minimum gas flow line when the cooktop appliance is in an automatic mode; a secondary line extending between the manifold and the gas burner, wherein a gas flow rate of the secondary line is controllable by a flow control valve; a primary valve in fluid communication with at least the primary line; and a control system including: a sensor configured to detect a temperature corresponding to the gas burner; and a controller regulating: (i) the flow control valve in response to the detected temperature to achieve a desired temperature, and (ii) the primary valve when the flow control valve is closed and the detected temperature exceeds the desired temperature.

A cooktop appliance includes a panel defining a plurality of openings. The panel may also include a plurality of clearance holes or a plurality of alignment slots, with each hole or slot positioned adjacent one respective opening. The cooktop appliance also includes a plurality of control valves mounted to the panel, each including a spark switch and a stem. The stem of each control valve extends through the panel at one corresponding opening. The cooktop appliance further includes a plurality of knobs, each knob mounted to a respective one control valve. The cooktop appliance also includes a unifying bracket positioned between the spark switches of the control valves and the panel. The unifying bracket includes a plurality of protrusions. Each protrusion may extend through a respective one alignment slot or through a respective one clearance hole.
