A fireplace assembly comprises a smoke chamber and a firebox in fluid communication with the smoke chamber. A masonry casing partially surrounds the firebox, the casing having a pair of spaced-apart side walls which together define an opening to the firebox. In one aspect of the invention, a lintel supports at least one chimney breast block across the opening, the lintel extending between the side walls and being supported by the side walls. In another aspect of the invention, a damper is mounted above the smoke chamber. In another aspect of the invention, the firebox is comprised of a plurality of firebrick, a metal firebox frame for guiding installation of the firebrick, and insulation between the firebox frame and the firebrick. In yet another aspect of the invention, insulation surrounds the back and sidewalls of the firebox and smoke chamber.

A rust proof indoor-outdoor convertible fireplace is provided with an open side having access into the combustion chamber box. The combustion chamber box is provided with an inclined bottom panel to drain water from rain and snow products from said combustion box. Support structures are provided on or above said inclined bottom panel for supporting a ceramic floor in a horizontal plane juxtaposed and above said inclined bottom panel. The inclined bottom panel is provided with a hole or aperture and forms the top panel of a water tight box that is used to house a gas control valve and electrical controls when the outdoor fireplace is converted from wood burning to a gas burning fireplace.

A fireplace appliance for warming room air without line electrical connection has a high efficiency thermoelectric generator having a heat-rejecting surface connected to a heat sink. The generator has a heat-receiving surface facing the site where a fireplace flame is to be located. In one embodiment the generator provides power to operate a fan that forces air through an air duct. The air duct has an inlet port receiving a flow of room air, and an outlet port. The heat sink is placed in the air duct where airflow generated by the fan moves across and cools the heat sink. The air heated by the heat sink flows to the room through the outlet port. One suitable material for the thermoelectric generator is a Bi—Te semiconductor. A number of options are shown that allow fan operation to commence properly while the appliance begins a cold start.

The invention relates to a masonry fireplace and a masonry fireplace log box fitted with a door (interior or exterior) or doors (both interior and exterior) that permits firewood to be loaded into the log box without need to carry wood through the interior of the home. Many masonry fireplaces that are constructed in new homes include a built-in log box (or firewood box) as part of the masonry structure. The log box consists of a recessed chamber with sufficient depth to allow a supply of firewood to be stored convenient to the fireplace without need to stack the wood on the hearth or the floor near the fireplace (or stove insert). With the present invention, the firewood is stocked into the log box from the exterior of the home and removed as needed from the interior opening of the log box. In the case of the single interior or exterior door, the door is insulated for energy efficiency and fitted with a locking mechanism to prevent entry by an intruder. For the case where both interior and exterior doors are provided, one door would be insulated and that door or the other would be provided with a locking mechanism. Hinge locations and bolts that attach the door(s) to the masonry structure are also designed to prevent intruder entry. A second embodiment is disclosed wherein the fireplace and the log box are non-masonry pre-asembled units providing the same advantages as the masonry embodiment.

A fireplace fountain having a base, a basin adapted to hold a liquid supported by the base, and a hood supported by the base over the basin. A fire pan is supported by the base over the basin and under the hood, with a burner being supported above the fire pan and adapted to be connected to a fuel source. A perforated tubing is supported in the hood, with a pump and supply tube connected thereto. The pump and supply tube are in fluid communication with the basin so that liquid held in the basin may be circulated by a pump to the perforated tubing. Liquid exits the perforated tubing and falls into the basin, but not into the fire pan so that the liquid does not extinguish any flame generated by the burner.

A fireplace system, constructed of modules including a firebox, a chimney housing, and a base, each module substantially a block of foam. The firebox has a fire cavity which is lined with fire resistant board to protect the foam from direct exposure to heat. The chimney housing has a central bore and a flue extending concentrically therethrough which has an inner tube in communication with the fire cavity and a concentric and spaced outer tube which is attached to the central bore to impede the flow of heat from the inner tube to the foam chimney housing. The chimney housing, base, and firebox are selectively attached together using connector sets which each include a pair of connection devices, one of which is partially submerged and anchored within the foam of each of the modules to be joined. The modules are joined by mating the connection devices of each connection set.

摘要:
Pollutants in the exhaust from wood burning in a fireplace are removed by positioning reticulated foam between the smoke chamber and the flue. The reticulated foam is a three dimensional latticework of interconnected ligaments forming a porous, open-celled structure with a large internal surface area. The internal surfaces are coated with a catalytic material which converts pollutants in the exhaust to harmless compounds. Heat from the exhaust, when the fire is burning, maintains the catalyst at a temperature for efficient conversion operation. Thermostatically controlled heaters are embedded in the foam, or thermostatically controlled electrical current is applied directly to the catalyst, to raise the catalyst temperature when the fire is growing or smoldering, periods during which the exhaust temperature is insufficient for good conversion operation.
