DE20317620U1 - Combined wood-fired oven and barbecue grill has easily removable heat storage bricks forming two baking chambers - Google Patents

Abstract

A combined wood-fired oven and barbecue grill has a lower housing section and an upper removable housing section with a chimney and integral heat storage bricks. The heat storage bricks are esp. easily removable and form two horizontal baking chambers one on top of the other, over the grate. The lower and upper heat storage bricks extend as far as the oven rear wall. The middle layer of fire brick extends as far as the door line, forming a uniform undivided flow of heat from the grate to the chimney outlet.

Description

Combination devices for baking and grilling usually either two fireplaces or are technical for use of the expensive charcoal fuel. They usually own no removable heat storage devices and are not designed to be permanently portable. Or you can use them to make tarte flambée and small baked goods, while for Baking bread the top heat is not sufficient.

The state of the art is documented under DE 201 12 218 U1 as well as G 86 26 071.5 and DE 203 03 184.9

The specified in the protection claim Invention is based on the problem that conventional wood bread ovens due to their weight with the firmly attached heat storage jacket and the connection are neither transportable to the underground nor in their previous execution can be used as a typical garden grill with wood firing, or yourself only suitable for baking smaller baked goods.

The requirement was one that could be changed outdoors, on a fireproof base or a portable base erectable device, that is fired with wood and both for baking bread, pizza as well as tarte flambé, as well as for grilling sausage and meat is.

The device has a closed, fireproof housing ( 9 ), preferably made of 3mm sheet metal. On the housing sides, handles are preferably attached, which are preferably made of U-shaped flat iron. The roof ( 2 ) is curved, with a frame fitted into the housing, which means that it can be put on and removed by hand. It is made of fireproof material, preferably 2mm sheet metal. In the rear part of the roof there is a round opening into which an upstanding nozzle ( 1 ) is welded, which is dimensioned in such a way that a commercially available stovepipe can be attached. On the front there are two double-walled doors, preferably insulated with rock wool. The housing base is covered with an insulation layer ( 4 ), preferably rockwool, which the lower heat storage elements ( 8th ), preferably FF stones, which serve as the baking surface of the lower baking chamber. A pocket, preferably made of angle iron, is welded onto the side walls of the housing, into which the side heat storage elements ( 6 ) are inserted. The middle heat storage elements ( 7 ), which allow a predetermined distance to the rear of the rear wall and reach up to the door stop at the front. The underside provides the upper heat of the lower baking chamber, while the upper side serves as the baking surface of the upper baking chamber. The side heat storage elements ( 6 ) of the upper baking chamber are inserted in identical bags as in the lower baking chamber. The upper heat storage elements ( 5 ) with overlying insulation layer ( 4 ) from the rear wall to the throttle valve ( 3 ). On the rear wall there is an insulation layer inserted from above between the lower and the upper heat storage elements ( 4 ) with a sheet metal cover ( 11 ), which are fixed by tabs attached to the side walls of the housing.

Function:

To light the fire, place a metal pan in the lower baking chamber that is open at the front ( 10 ) posed. The door of the lower baking chamber remains slightly open during the firing phase by snapping the door latch into the corresponding notch in the counterpart. This ensures that the furnace is pulled. If the wood has burned down to the embers, the tin pan with the embers is removed from the oven by inserting two handles into the receptacles provided, which saves sweeping out the lower baking chamber. The arrangement of the heat storage elements provides a uniform, undivided heat flow from the fireplace to the fume cupboard. This causes both baking rooms to heat up evenly. The insulation layers together with the heat storage elements provide enough heat storage capacity to bake bread in both baking rooms.

For grilling, the middle heat storage elements ( 7 ) removed and replaced by a grillage. By remaining the remaining heat storage elements in the oven it is achieved that the food to be grilled is evenly grilled. While with the conventional grill the food to be grilled has to be turned over, this can be omitted here, since the baking room doors can be closed by the special design of the grillage.

Summary:

With the invention of a portable Wooden oven with two on top of each other lying baking rooms, which can be converted into a garden grill in just a few steps the properties of two devices are combined in one. By the easy removal of the heat storage elements the weight of the oven can be reduced to ¼. The order of the heat storage elements and the insulation layers provide even and sufficient heat for Baking bread. The fact that the oven in the lower baking room with a Removable fireplace is heated, there is no need to sweep the lower baking room and you can have bread or Bake tarte flambée.

When replacing the middle heat storage elements with a grill, the Wood oven a garden grill, in which the special design of the grillage makes it unnecessary to turn the food.

Claims (1)

The invention relates to a combination of a wood-burning oven and a wood grill comprising a lower housing part and an upper, removable housing part with a smoke exhaust and integrated heat storage elements, characterized in that the heat storage elements are easily removable, and form two baking rooms one above the other with a fireplace, the lower and upper heat storage elements up to the rear wall of the housing, the middle heat storage elements up to the door stop to the front, whereby a uniform, preferably undivided heat flow from the fireplace to the fume cupboard is specified.
