The cooker, object of the invention, has the

following features:

1° The focus lies in beneath the furnace (the der-

negate being in the focal point axis or offset on the right

or on the left-hand side). This is of the type with combustion-

a through the mass;

2° The direct radiation to the fuel

ignition is absorbed by a plate, the face

lower is smooth and the upper face of which com-

door cooling ribs. The plate

constitutes the radiant element for heating air

to to the temperature of the furnace and heating

the workpiece;

3° The heating of the furnace is performed by circulating

hot air on its lower walls, and side

rear. An air inlet and provided on the

front and the heated air outlets, on the behind

of the stove, in the bottom (facing the air duct

lower hot) and above (face to the conduits

right and left side);

4° The heated air flowing out of these ducts is cana-

[...] by a hood attached back of the-

apparatus and opening behind and on top. The

hood heats the rear face of the

furnace. The temperature thereof is be

perfectly distributed;

5° The hot air leaving apertures of

the hood and on the work table is for the

heating of the room;

6° Heating of the work table is provided

by the hot combustion gases channelled at the

outlet of the furnace by two conduits insulated (in

the case where the furnace is in the focal point axis), or

by a single larger thermally insulated conduit

dimension (in the case where the furnace is offset by

respect to the axis of the focus);

7° The baking tray of the work table is

light alloy aluminum-based stainless

to increase its conductivity. It is provided

of fins forming baffles to increase

the heating surface and thereby, improve the

performance of the device;

8° The loading of the focus is operated by the front of the focus, the fuel being guided by a top loading.

The advantages of the stove are as follows:

a. Possibility of placing a furnace and a focal point with a small stove (dimensions of the body 56 X 60);

b. Circuit of fumes rather than forcing them to descend as in appliances flashback, the growth is improved even when the apparatus is connected to a poor chimney;

c. In the case where the stove is equipped with a focus boiler, it is possible to install radiators on the same level as the stove;

d. Better heat distribution on the cooktop, the hot combustion gases sweeping the entire surface thereof;

e. Very easiness of cleaning due to the accessibility of two vertical conduits fumes minus the lower ports are in direct communication with the focal point;

/. The sides being heat-insulated, the temperature of the flue gas is retained within the apparatus. The calories is retrieved at maximum for the heating of the cooktop;

g. Heating system the premises by mouths of hot air coming out at high temperature.
