Abstract: A fast-assembling stove includes a stove body having two opposite sides to which two foldable cabinets of substantially the same top levels as a cooking surface are respectively coupled. Each foldable cabinet includes a collapsible frame rotatably coupled to inside and outside boards, a back board, a top board, and a bottom board coupled to circumferences of the inside and outside boards, and a front door panel. The stove body includes a cooker below which a central partition board is mounted. The inside board is shorter than the outside board, so that a gas hose extending from a gas canister received in the cabinet is allowed to extend through a gap between the top board and the inside board to couple to the cooker. A coupler mechanism is formed between top flanges of the outside board and the back board and the bottom of the top board.

Abstract: A multi-function roaster system includes a roasting oven serving as a main body formed by two oven sidewalls to which a liftable cover is rotatably mounted.

Abstract: A lighting device is provided for a roasting zone of an outdoor barbeque table, wherein a flap-up cover is provided for a roasting tray and has a flapping edge from which a handle projects outwards. The handle receives an electrically-powered lighting assembly therein at a suitable location for illuminating inside of the cover. With the handle is located further from the roasting zone than a wall of the roasting tray, and further with the roasting tray cover featuring heat isolation and dissipation, heat generated by the roasting zone does not directly impinge and thus damage the electrically-powered lighting assembly. Light is projected into the cover, rather than toward a user's eyes to dazzle the user. In this way, the lighting of the outdoor barbeque table can be improved and is more reliable and durable. Assembling and replacement/maintenance can be made simple and the structure simplified and costs reduced.

Abstract: An atmospheric heater has opposite side walls each forming a groove for receiving a retention rail with an opening of the retention rail exposed to receive and retain a fogged light-transmitting tube, which is spaced from a bottom wall of the retention rail to define a first channel.
