Portable grills are disclosed. An example portable grill movable between an erected configuration and a collapsed configuration includes a frame, a cookbox, a lid, and a lid lock assembly. The cookbox is coupled to the frame. The lid is movably coupled to the cookbox. The lid is movable relative to the cookbox between a closed position and an open position. The lid lock assembly is coupled to the frame. The lid lock assembly is configured to enable movement of the lid from the closed position into the open position when the portable grill is in the erected configuration, and to lock the lid in the closed position in response to the portable grill being moved from the erected configuration into the collapsed configuration.

Portable grills are disclosed. An example portable grill movable between an erected configuration and a collapsed configuration includes a valve and regulator assembly and a tank blocker. The valve and regulator assembly includes a tank connector configured to removably couple a fuel tank to the valve and regulator assembly. The tank blocker is configured to prevent the portable grill from being moved from the erected configuration into the collapsed configuration when the portable grill is in the erected configuration and the fuel tank is coupled to the tank connector.

Portable grills are disclosed. An example portable grill movable between an erected configuration and a collapsed configuration includes a frame, a leg unit, and a leg lock assembly. The leg unit is movably coupled to the frame. The leg unit includes a first leg and a second leg spaced apart from the first leg. The leg lock assembly is operatively coupled to the leg unit and located partially within the frame. The leg lock assembly is configured to lock the leg unit in a first position relative to the frame when the portable grill is in the erected configuration, and to unlock the leg unit from the first position to enable movement of the portable grill from the erected configuration into the collapsed configuration.

Portable grills are disclosed. An example portable grill includes a cookbox, a lid, a cooking grate, and a grate retainer. The lid is movably coupled to the cookbox, and is movable relative to the cookbox between a closed position and an open position. The lid and the cookbox define a cooking chamber when the lid is in the closed position. The cooking grate is located within the cooking chamber and supported by the cookbox. The cooking grate is movable relative to the cookbox when the lid is in the open position. The grate retainer is coupled to the lid, and extends inwardly from an inner surface of the lid. The grate retainer is configured to restrict movement of the cooking grate relative to the cookbox when the lid is in the closed position.

A system for igniting a grill can include a solenoid valve, a flame rectification sensor, an igniter, and a control circuit connected to the solenoid valve and the flame rectification sensor. The solenoid valve controls flow of gas to the grill's burner and includes a switch that closes when a handle connected to the switch opens the solenoid valve. The control circuit sends current to the solenoid valve when the switch is closed to hold the solenoid valve open. After the switch closes, the igniter is ignited. After ignition, the control circuit monitors the presence of a flame with a flame rectification sensor. If no flame is detected after a certain amount of time, the control circuit stops sending current to the solenoid valve to close the solenoid valve.

A joint, a knob assembly, and an appliance having a joint and a knob assembly are provided. The joint may include a housing, a first shaft support, a second shaft support, and a coupling shaft. A slot having a predetermined width extending in a circumferential direction of the housing and a predetermined length extending in a longitudinal direction of the housing may be formed in the housing. The coupling shaft provided in the second support may include a rotary shaft rotatably inserted into the slot. A stopper may be formed to protrude from an outside of the rotary shaft, and a position of the stopper inside the slot may be changed according to rotation of the rotating shaft. The stopper may be provided in the slot so that the stopper interferes with an inner wall of the housing formed by the slot at a predetermined position.

A regulating valve with at least one gas outlet conduit and a housing having at least one outlet hole in fluid communication with the outlet conduit; a rotating disc arranged in the housing; a spring axially retaining the rotating disc in the housing; and sealing means surrounding the at least one outlet hole. The sealing means includes a gasket having a closure member associated with each outlet hole, surrounding the same, and at least one attachment arm attached to the at least one closure member. The attachment arm including at least one protuberance, with the rotating disc being supported on the closure members and on the protuberances when it presses on the gasket.

The control circuit sends current to the solenoid valve when the switch is closed to hold the solenoid valve open. After the switch closes, the igniter is ignited. After ignition, the control circuit monitors the presence of a flame with a flame rectification sensor. If no flame is detected after a certain amount of time, the control circuit stops sending current to the solenoid valve to close the solenoid valve.

The present invention discloses a regulating mechanism regulating the flows from a plurality of gas outlets in a fuel gas valve, comprising an actuator, a push rod, a presser plate assembly, regulating rods and a valve body. Wherein the valve body has a plurality of gas outlets, a regulating rod is provided in each regulating port which exists between the gas inlet and each gas outlet, a resetting device is provided between each regulating rod and the valve body, and the actuator drives the push rod which is around by the regulating ports to move along the axis. The push rod causes the presser plate assembly to move up and down to press or relax the regulating rods and simultaneously change the degree of opening between the head portion of each regulating rod and the corresponding regulating port so that the flow from each gas outlet changes synchronously.

According to one embodiment a gas tap is provided that includes a manually operable shaft having a first end coupled to a regulating element and a second end configured to be coupled to a knob that can be operated by a user. The shaft includes a first locking element, and the gas tap includes a second locking element. The shaft is rotational between an initial angular position and a final angular position, and is axially movable when it is arranged in the initial angular position between a first axial position in which the first locking element and the second locking element cooperate with one another, preventing the shaft from being able to rotate, and a second axial position in which the shaft is able to rotate. The user has to pull on the shaft in order to move it from the first axial position to the second axial position.
