A portable propane fuel heater assembly for heating a room with propane fuel includes a fuel tank that contains liquid propane. A supply hose is fluidly coupled to the fuel tank for receiving gaseous propane from the liquid propane. A heater is provided and the heater is positionable in a room in a building. The supply hose is fluidly coupled to the heater thereby facilitating the heater to receive the gaseous propane that gaseous propane from the liquid propane. In this way the heater can burn the gaseous propane for heating the room in the building. Additionally, the heater has an exhaust duct for venting combustion gases outwardly from the heater.

A capacitive sensor and control system is configured to detect the presence (or absence) of fluid within a container. Configured in a vat or frypot of a deep fryer, the sensor determines when a level of liquid within the frypot is at or above the level of the sensor. The sensor is in communication with the control system and the sensor sends a signal to the control system representative of the presence or absence of liquid within the frypot and at the level of the sensor. The controller receives the signal from the sensor, and allows operation of the one or more heat sources for heating the frypot when the signal received from the sensor is representative of liquid being disposed within the frypot at or above the level of the sensor, and prevents operation of the one or more heat sources when the signal received from the sensor indicates that liquid is not disposed within the frypot at or above the level of the sensor.

A home cooking appliance includes a housing, a cooktop on the housing, the cooktop having at least one gas burner, a cooking compartment in the housing and accessible through a door in a front of the housing, a cooling air system having a cooling fan that conveys cooling air through the housing, and an air guide between the cooktop and the cooking compartment, the air guide including an inlet located away from a space below the at least one gas burner of the cooktop and an outlet in fluid communication with the cooling fan, the air guide configured to restrict air from being drawn into the cooling fan from the space below the at least one gas burner of the cooktop.

A portable heater can include a housing including a base and an enclosure and a burner assembly disposed within the enclosure, the burner assembly including a heating surface, wherein the enclosure and the heating surface are rotatable, with respect to the base, between a first rotational position and a second rotational position. In some examples, the heating surface is a curved surface. In some examples, a tilt switch is provided that has a position that is independent of the rotational position of the enclosure. The portable heater can also include temperature control features for maintaining fuel tank temperature at an improved operating condition.

A gas burner assembly may include a gas burner and a burner cap. The burner may include a distribution cavity fluidly coupled with a gas inlet and a plurality of gas discharge ports. The burner cap may have a glass body characterized by a peripheral edge, and a metal element encapsulating the peripheral edge. The glass body may overlie at least a portion of the distribution cavity, and the metal element may shield the peripheral edge.

A portable outdoor stove comprises a gas control valve, the gas control valve being dockable by a fuel supply means; a burner unit provided on the gas control valve; a plurality of supports attached to the portable outdoor stove, the supports being foldable at least between a first position and a second position; wherein in the first position, the supports are adapted to provide a hold for a receptacle such as a pot to be heated by the burner unit; wherein in the second position, the supports are adapted to form a cover around the burner unit such that the burner unit does not project outside the cover.

A compact non-rotational mounting feature or mechanism is employed for mounting an orifice holder to a support member below a cooktop of a gas cooking appliance. More specifically, the holder and support member include interengaging polygonal structure, such as a key-shaped anti-rotational peg and hole combination, allowing the holder to be initially mated with the support member in a manner which prevents relative rotation and assuring that the holder is appropriately positioned for proper alignment of various gas burner components, such as an orifice, a gas line, electrode, flame spreader and other burner related structure. Upon exacting the positioning of the holder relative to the support member, the holder to fixed in position by a mechanical fastener.

A gas burner includes a burner body that defines a fuel chamber and a plurality of flame ports. The plurality of flame ports are configured for directing a flow of fuel and air out of the fuel chamber. The plurality of flame ports are distributed along a circumferential direction on the burner body such that the plurality of flame ports are uniformly spaced from a center of the fuel chamber along a radial direction. The plurality of flame ports may be oriented to direct flames away from a void within the plurality of flame ports.

A cooktop and appliance is provided that may include a first hob zone having a fixed gas receptacle, a first interchangeable burner, a second interchangeable burner, and a first gas flow switch. The first interchangeable burner may be selectively positionable at the first hob zone and define a fuel output area. The second interchangeable burner may also be selectively positionable at the first hob and may define a fuel output area smaller than the fuel output area of the first interchangeable burner. The first gas flow switch may be disposed at the first hob zone to selectively engage one of burners. The first gas flow switch may include a valve upstream of the fixed gas receptacle to selectively restrict gas flow upon engagement of the first gas flow switch with one of the first interchangeable burner or the second interchangeable burner.
