A burner head of a burner for a gas cooktop, a burner, and a gas cooktop are provided. The burner head includes a plurality of supports, where each support includes a support surface for supporting a cooking utensil, the support is further provided with a plurality of gas ports from which gas flows out and forms a flame, and each support has a first working position and a second working position. When the supports are in the first working position, the burner head has a flat upper surface, and the support surfaces of the supports constitute the upper surface, and when the supports are in the second working position, the burner head has a concave surface, and the support surfaces of the supports constitute the concave surface. The shape of the burner head is changeable, so as to adapt to cooking utensils having different bottom outlines.

An incinerating container for grills and similar broilers. The incinerating container receives products of combustion from a gas burner or hot gases from an electric element or other heat source. Apertures in a top of the incinerating container receive oil into the incinerating container, such as oils from melted fat as food cooks. The oils are incinerated within the incinerating container. The apertures formed in the top allow hot oils to enter the incinerating container for combustion of the oils within the incinerating container, and are constructed to prevent flames from materially exiting the incinerating container.

A cooking grate includes a peripheral frame defining a periphery of the cooking grate, a plurality of fingers extending from the peripheral frame toward a center of the cooking grate, and a slot formed in the peripheral frame, the slot forming a passageway through the peripheral frame from a lower portion to an upper portion thereof in the vertical direction.

A cooktop appliance includes a gas burner disposed on a panel of the cooktop appliance and a grate with a plurality of fingers positioned above the gas burner. The plurality of fingers includes a sensor finger. A temperature sensor is mounted to the sensor finger of the plurality of fingers of the grate. The temperature sensor includes a first temperature probe extending above a top surface of the sensor finger at a first end of the sensor finger and a second temperature probe positioned within the sensor finger between the top surface of the sensor finger and a bottom surface of the sensor finger.

An error-proof operating system for a portable gas hob includes a gas tank cavity partition having two ends respectively fixed to a front panel and a back panel, wherein a bounce limiting device is provided on the gas tank cavity partition, the bounce limiting device is connected to an actuating rod, the actuating rod is rotatably connected to the gas tank cavity partition, one end of the actuating rod penetrates through the front panel, and a top of the bounce limiting device is not lower than a bearing end for bearing a liquid holding tray. The beneficial effect of the present invention is: by providing the bounce limiting device and using same in conjunction with the liquid holding tray, user's operation is standardized to avoid dangerous accidents caused by incorrect operating.

A domestic cooking stove comprises a frame that mounts a primary tube, one or more of nozzles for fuel injection, knobs for controlling the fuel injection, mixing tubes for modulating pressure gradient, burner tops for combustion of the air fuel mixture, and pan supports to support the vessel, heat reflectors to reflect heat, and legs to support the frame. Each heat reflector is positioned above burner top to provide secondary air entrainment for combustion by reducing a gap between an inner circumference of heat reflector and an outer circumference of the burner top to minimize heat losses. The heat reflector has a curved orientation to reduce heat transfer in a downward direction and generates eddies that increases heat transfer towards vessel bottom. The legs are positioned below the frame and has a predetermined height to maintain a gap between table top and the frame bottom surface for entrainment of air.

The present disclosure relates to an electric cooktop safety system. More particularly, the electric cooktop safety system pertains to safety cookware vessels having special fastening components that secure these safety cookware vessels to an electric cooktop, preventing a user from accidentally tipping or pulling off the safety cookware vessels from the electric cooktop. In one implementation, the fastening components may include a safety stem having keyed members and stem locking members disposed on a safety cooktop to secure the safety cookware vessel to the safety cooktop. In another implementation, the fastening components may include electro-magnetic fastening components to secure the safety cookware vessel to the safety cooktop.

A pan support according to the invention for a gas stove comprises a support structure for a pan having a support surface for the pan, a chamber for a gas, in particular for an inflammable combustion mixture, the chamber being arranged in the interior of the support structure. Gas outlet openings are provided at the support structure and have a fluid connection to the chamber. The chamber has a circumferential geometry when looking from above.

A barbecue grill includes a barrel and a supporting unit. The barrel includes multiple panels and two lugs. The panels are pivotally connected to one another so that the barrel is switchable between an extended position and a collapsed position. The lugs are formed on one of the panels. The supporting unit includes a frame and multiple loops. The frame includes two lateral sections and two pivots. The lateral sections extend parallel to each other. The pivots extend from the lateral sections, respectively. The pivots are inserted in the lugs when the lateral sections are released. The pivots are disengaged from the lugs when the lateral sections are moved relative to each other. The loops are located on and connected to the lateral sections.

Disclosed herein is a portable roaster used when outdoor cooking or camping is enjoyed. The portable roaster with improved portability and handleability can be changed into a single briefcase form so that it is easy for the user to carry it, can accommodate a windshield, a vertical transfer part, a charcoal plate, and a grill inside the body of the portable roaster so that meat can be grilled and eaten by, e.g., a barbecue grilling method outdoors through easy assembly, it is convenient to store portable roaster in a vehicle or warehouse, and the handling of the portable roaster is very convenient, and allows a cover to be used as a substitute for a table so that the portable roaster is highly versatile.
