A cooktop appliance includes a gas burner, a user input configured to define a power setting of the gas burner, and a grate. The grate includes a sensor finger with a temperature sensor mounted thereto. The temperature sensor includes a first temperature probe extending above a top surface of the sensor finger and a second temperature probe positioned within the sensor finger. The cooktop appliance also includes a controller in communication with the temperature sensor. The temperature sensor is configured to transmit a first temperature measurement from the first temperature probe and a second temperature measurement from the second temperature probe to the controller. The controller is configured to determine a temperature of a cooking utensil positioned on the top surface of the sensor finger based on the power setting defined by the user input, the first temperature measurement, and the second temperature measurement.

The disclosed technology includes a water heater system having a blower, an igniter, a burner, a heat exchanger, and a refractory configured to attach to the burner and the heat exchanger. The refractory can include a unitary ceramic housing having a top and a plurality of sidewalls and be configured to retain heat from combustion gases. The top can have a burner aperture configured to receive at least a portion of the burner and the plurality of sidewalls can form a cavity configured to receive at least a portion of the heat exchanger. One or more of the sidewalls can additionally have a protrusion extending laterally along an inside surface of the sidewall that is configured to contact the heat exchanger to form a seal between the heat exchanger and the refractory. A sealing material can substantially create a seal between the refractory and the heat exchanger.

A safety switch for use in a gas combustor is disposed on a gas combustor having a rear opening, and a press button is arranged adjacent to the rear opening; the safety switch includes a locking member and a swing arm, the locking member has a main body sleeved with a longitudinal spring, and a locking hook protruded from a location towards a latching hook arranged above the swing arm, wherein a transversal spring is disposed between an extending sheet below the swing arm and the inner wall of the gas combustor; when the locking member is not pressed, the locking hook is abutted against the latching hook, a locking bolt protruded from a bottom end of the press button is abutted against the locking hook, so that the press button is unable to be pressed, thereby forming a locked status.

Burner (10), in particular for a vehicle heater (12), having an orifice plate (14) separating an inner combustion region (16) from an outer region (18), wherein a photosensitive sensor (20) is arranged in the outer region (18), wherein at least two separate air inlet openings (22, 24, 26, 28) are being provided in the orifice plate (14), wherein one of the at least two air inlet openings (22, 24, 26, 28) is additionally formed as a light opening (28) which also allows light to pass from the inner combustion region (16) to the photosensitive sensor (20) that is arranged in the outer region (18), wherein the at least two air inlet openings (22, 24, 26, 28) are being shaped such that the same combustion air quantities flow into the internal combustion region (16) per unit time, respectively, and wherein the orifice plate (14) is transparent and/or the light opening (28) has a shape different from the air inlet openings (22, 24, 26) that are not formed as light opening such that an illumination area defined by the light opening (28) is larger than a reference illumination area defined by one of the at least two air inlet openings (22, 24, 26) that are not formed as light opening (28).

A cooking appliance and method generate an audible and/or visual indication to a user when a user control for a gas burner is in a position within which an igniter is active and a gas valve is supplying sufficient gas flow to the gas burner to support ignition and thereby assist a user in properly positioning the user control during ignition of the burner.

A temperature sensor (1) for gas burner (2) having a thermocouple (11) comprising electric conductors (15) and a connection element (12) to connect to the burner (2) associated with a free end (18) of such thermocouple (11), said connection element (12) being suitable for being inserted inside a seat of the sensor (8) formed inside a wall (4) of the burner (2) and having a first end (26) suitable for being placed at the outer surface (6) of the burner (2), said thermocouple (11) being inserted inside a blind hole (29) of the connection element (12) which opens at a second end (28) of said connection element (12). Said blind hole (29) ends with at least one part (31) convergent towards an end zone (K) of the hole (29), said part (31) getting in contact with the thermocouple (11) inserted inside the connection element, the connection element (12) being made from an iron-chrome-aluminum alloy. An assembly comprising such temperature sensor and a burner is also claimed.

A burner has a body suitable for containing at least one injector, a crown disposed on the body, and a cap disposed on the crown. The geometrical structure of the crown and of the cap is such to stabilize the flames with a minimum contact between the flames and the cap, in such a way to minimize the temperature of the cap when the burner is used.

A burner gun includes a case, an ignition device, a switch and a operational part. By the switch and an operation rail in the case, the ignition device can only be activated by correctly operating the switch and pulling the operational part. The ignition device cannot activated by pulling the operational part if the switch is not correctly operated, so that the ignition device is prevented from being activated unintentionally to reduce possibility of causing fire disasters.
