Abstract
ABSTRACT OF THE DISCLOSURE
A fire-place unit which distinctively includes a cookery oven in combination therewith and laterally opposite internal air spaces whereby the fire-place unit has the aesthetic enrichment of a stove appearance and also acts as a hot air furnace of the gravity circulation type with heat dissipation effect by air circulation in these lateral air spaces. This fire-place combination unit com-prises a casing having a rear portion insertable in a wall or partition and a wider front portion operatively positioned forward of the wall and unconspicuously concealing the narrower rear portion, a fire-place combustion chamber, a cookery oven in the casing over the fire-place combustion chamber and spaced from the laterally opposite walls by lateral air space, a pair of upwardly spaced grilles on each side of the wider front portion in communication with the corresponding lateral air space.

Description
This invention relates ~o a fire~place and, more partic-ularly, to a fire-place unit of the type whlrh acts as a conventional fire-place and which is also adapted to cook foods.
Fire-places of the above type have anteriorly been proposed -but they merely cook foods by placing the cooking ware on the heated top thereof or by suspending the cooking ware over or adJacent the fire in the fire place combustion charnber. As far as cooking is concerned, the previously proposed fire-places are not satisfactoxily efficient. Besides, they have only the appearance of a conventional fire-place.
It is a general object of the present invention to provide a fire-place unit of the above type which provides the advantages of oven cooking and the aesthetic enrichment of a stove appearance produced by the presence of a cookery oven~ ;
It is another object of the present invention to provide a fire-place unit of the above type which acts as a hot air furnace of the gravity circulation type.
It is a more specific object of the present invention to ^ ~ !
provide a fire-place unit which has a rear portion insertable in a wall or partition and unconspicuously concealed behind a wider external front portion and which also has laterally opposite In~ernal spaces extending ln both the front and the rear portion and allowing upward ~
air circulation and heat dissipation in both the front and the rear ~ ;
portions and thus producing a hot air furnace effect and a beneficial cooling or ventilation between the combustion chamber and the wall .~.~ . .
or partition in which the rear portion is engaged.
The above and other objects and advantages of the -present invention will be better understood with the following detailed ~-; description of a preferred embodiment thereof which is illustrated, -~' 30 b~ way of example, in the accompanying drawings, in which:

and a pair of front doors 15. The slde walls 11 and 12 are inwardly spaced from the laterally opposite side walls oE the casing and in tight edgewise engagement with the top portions 4 and 5, the back wall 3 and a generally H-shape fron~ wall member 16 to form a lateral air space between each side wall of the casing and the corresponding side wall of the oven~ Each side wall extends down to the floor of the combustion chamber~ so that each of these lateral air spaces forms an air passage for upward air circulation serially through the bottom ~-grille 8, the lateral air space and the top grille 9. An elongated ~ .
baffle or heat deflector plate 17 is secured in each of the afore-mentioned air spaces and extends upwardly and rearwardly from the front .:

A smoke stack lô rises from the bottom 13 of the oven and out- ¦
wardly e~tends through the rear top portion 4. The back wall 14 of the oven enclosure is inwardly spaced from the back wall 3 of the ;~
casing to form a back space communicating the fire place combustion ;~ :
chamber below the oven with the smoke stack 18~ A smoke draft damper 19 iS pivotally mounted in the smoke stack 18 and rigidly connected to ,;
an actuation arm 20. A push bar 21 is connected to the free end of the actuation arm 20 and is provided with an external handle 22 to manually control theldamper:'l9 and thus the draft in the smoke stack 18.
The front doors 15 are hinged at their lateral outer edge to open and close in opposite angular direction~ A front shelf 23 projects ~-edgewise forwardly of front wall member 16 and in co-planar relationship with the bottom 13 of the oven enclosure. ` ~

from direct contact wlth the overlying cookery oven. I~ must be noted that the heat deflector plate 24 centrally bulges away from the bottom wall 13 of the oven, such as ~o evenly spread the heat ~cross the width of the oven.
The flre-place unit also includes a baseplate 25 extending coextensively with the floor area defined by the fire-place combustion chamber; that is~ inwardly of the back wall 3 and of the side walls 11 and 12.
The fire-place unit may be sold separate or in combination with a base 26~ of any appropriate heat- resistantconstructlon~ sueh ., :
as of conrrete blocks. The fire-place unit may be installed with its ~; b~ck wall 3 against a layer of insulation 27, as show~ in Fig~lre 3~ or with the narrower portion 1 inserted in a wall or partition 28~ as shown in dashed line in Figure 1.
It must be noted that the oven is positioned in a heated .1 : "
environment and is heated from both sides~ the rear~ the bottom and even from inside by the smoke stack 18. Besides, the lateral air spaces ~ -and the grilles 8 and 9 allow to heat the air of the room in which it ~1 is installed and to coole the external side wall of the casing or safer i~stallation.
