A gas burner assembly for a cooktop appliance includes a normally aspirated primary burner and a concentrically-positioned forced air boost burner. A dual-outlet solenoid valve receives fuel from a fuel source and selectively directs the fuel to a first solenoid outlet in fluid communication with the primary burner and a second solenoid outlet in fluid communication with the boost burner. The solenoid valve is positionable in a first position where the first solenoid outlet is substantially open and the second solenoid outlet is substantially closed and a second position where the first solenoid outlet is partially open and the second solenoid outlet is substantially open.

A windproof outdoor heater burner includes a casing and a flow-guiding device. The casing includes an inlet and an outlet. The flow-guiding device includes an inlet pipe connected to the inlet, a flow-guiding member, and a diffuser plate connected to the outlet. The flow-guiding member is connected to the inlet pipe. The flow-guiding member includes a flow-guiding channel therein and a plurality of first through-holes. Each first through-hole includes a first end intercommunicated with the flow-guiding channel and a second end intercommunicated with a chamber of the casing. The diffuser plate includes a plurality of first exhaust holes located between two sides thereof and intercommunicated with the chamber of the casing. The first exhaust holes are not aligned with the flow-guiding member.

A heater with a visual flame display is described. The heater may include a top portion and a base, separated by concentric cylinders. The innermost cylinder houses a flame element, which may be spun into a vortex. The cylinders may be constructed from transparent materials such that the flame element is visible to an observer. The base provides heat at or near ground level for efficient heat distribution.

An apparatus includes a high-pressure tank, a controller, a valve, controlled by the controller, and a heater.

A system and methods of preventing the rapid cooling of a fuel supply to a portable stove.

A cooktop appliance includes a gas burner assembly positioned on a panel of the cooktop appliance at a top surface of the panel. The gas burner assembly includes a grate configured for supporting a cooking utensil. The grate defines an internal fuel passage. The internal fuel passage of the grate extends to a burner such that fuel is directed to the burner via the internal fuel passage of the grate.

A cooking appliance includes an air frying system. The air frying system may include a heating element. The air frying system may include a fan. The heating element and fan may be positioned over the top of an oven cavity. The air frying system may be in fluid communication with the oven cavity.

A heater assembly can be used with a gas appliance. The gas appliance can be a dual fuel appliance for use with one of a first fuel type or a second fuel type different than the first. The heater assembly can include at least one pressure regulator, a housing, and an actuation member. The housing has a first fuel hook-up for connecting the first fuel type to the heater assembly, a second fuel hook-up for connecting the second fuel type to the heater assembly, and an internal valve. The actuation member can control the position of the internal valve based on whether the first or the second fuel hook-up is used.

A hybrid oven comprising an oven case; an upper cover is hinged on an upper part of the oven case; wherein a control panel is provided at an upper part of a front surface of the oven case; a lower part of the oven case is provided with an oven; a back panel inside the oven is provided with electrical heating elements; a bottom part inside the oven is provided with gas heating elements; the electrical heating elements and the gas heating elements are electrically connected to the control panel.

A heater dolly for use with an outdoor patio heater includes a platform assembly and a retention assembly constructed to extend between the platform assembly and the outdoor patio heater in a manner providing additional support and ensuring that the outdoor patio heater and platform assembly are securely connected to enhance stability of the outdoor patio heater as it sits upon the heater dolly.
