Description

Cooking stove with built-in kettle and two different heights Grating There are already stoves with built-in kettles and two of different heights lying grates known, the lower one permanently installed and the upper one from his horizontal position can be folded down and so the firebox for the lower grate releases. With these. the two grate points lie vertically in a furnace one above the other, which is bordered on three sides by boiler walls, while the fourth Side is formed by a stove wall, - in whose niche the upper grate when folding down can put in. The withdrawal of the fire gases generated in the lower furnace consequently takes place in the same way as those produced in the upper furnace chamber Draw off heating gases. This means that the heating gases are also activated when the stove is in operation Part of the heat is unnecessarily withdrawn from the boiler, the walls of which are in the upper part Part directly adjacent to the upper combustion chamber. On the other hand, when the boiler is in operation the stove was also smeared with the gases from the fire. As a result, a lot is going on `` 'Warmth lost, and, especially in summer, there can be severe overheating of the kitchen. This overheating can also occur in winter, e.g. B. with simultaneous heating and cooking operation, occur when the stove is heavily fired.

To avoid this; is the subject of the invention The lower firebox is connected directly to the stove with its own smoke outlet Puffs of the boiler, which is protected against the flue gases of the upper furnace, are connected and furthermore the lower grate is arranged offset with respect to the upper grate, that it is outside of the ash fall area .of the upper grate under a partition comes to rest, which shields the stove top from the lower furnace and is attached in the extension of the upper grate. The upper grate can be foldable in a trough of a sloping wall, which is under your upper grate of starting from the front hearth wall up to the front grate bearing of the lower grate and an opening located below the upper grate opening for an ash trap and at the same time forms an air inlet that can be closed when the boiler is in operation. is the fold-down grate is provided with a plate-like extension, so can these as Abschlussglie.d for the inclined wall opening serving as ash fall and air inlet Find use.

The drawing shows an embodiment of the subject matter of the invention shown in a vertical section from front to back through the furnace.

A grate b that can be folded up and down around a hinge of the front edge is built into the kitchen stove above a lower, stationary grate a. A lever linkage c is used to move the latter. The lower grate a is opposite .dein upper grate b offset to the rear so that it lies under the forward-projecting ceiling of the lower furnace and is supported with its rear edge on the boiler wall. The boiler is completely covered from the upper hearth except for its upper wall. A special heating gas outlet R leads to the boiler flues from grate a. The stove plate is largely protected against the influences of the heating gases generated in the lower combustion chamber when the boiler is in operation by the protruding ceiling of the lower combustion chamber. When the upper grate b is folded down, it can be inserted into a niche or trough e in the end wall of the lower furnace chamber, which slopes downwards from the front edge of the upper grate opening to the front edge of the lower grate seat,> o that the upper grate opening is completely free. In the inclined wall below the grate opening, that is to say below this grate when the grate b is folded up, an opening f serving as an ash drop is provided. This connects the lower furnace with the fresh air passage of the stove, into which the outside air enters through the inlet (1. When the grate b is completely folded down, this opening f is covered and closed by a plate-shaped edge g of the red.

During cooking, the fresh air entering at d pulls through the Opening f to the upper grate, whereby the boiler passages are expediently completely closed. No fresh air will then reach the lower grate. At the. Boiler operation on the other hand and when the upper grate b is completely folded down, the air on path F is drawn in as the first air to the grate n, the opening f being closed. As with mixed operation can you can also carry out a special flue gas combustion by supplying secondary air, by lifting the grate b with the edge plate g slightly from the opening f. By Adjusting the grate in any desired intermediate position with the help of Notches lc can be regulated in terms of quantity.

Laying the fire from top to bottom is easy Fold down the upper grate. However, when the fire is moved from the bottom up should be, the glowing fuel with the help of a scraper or something similar Tool as far as possible in front of the lower part of the inclined grate b sloped so that it is taken along when the grate is raised. i

Claims (3)

PATENT CLAIMS: i. Cooking stove with built-in kettle and two different ones high-lying grates, the lower one permanently installed and the upper one from his can be folded down in the horizontal position and thus the combustion chamber for the lower grate releases, characterized by the union of the following features: a) The lower The combustion chamber (h :) is directly adjacent to the trains thanks to its own smoke outlet (R) .the boiler, which is protected against the flue gases of the upper furnace '(H), is connected. b) The lower grate (a) is arranged offset in relation to the upper grate (b), that he is outside the ash fall area of the upper grate under a partition (h) comes to rest, "- which shields the stove top (g) from the lower combustion chamber and in overtime .the upper grate is attached. 2. Cooking stove according to claim r, characterized in that the upper grate (b) is in a Trough (e) a sloping wall (i) is foldable, which is under the upper grate of the from the front wall of the stove to the front grate bearing of the lower grate (a) and an opening (f) located below the upper grate opening which has a Ash fall and at the same time an air inlet that can be locked when the boiler is in operation forms. 3. Cooking stove according to claim 2, characterized in that as a terminating element for the inclined wall opening (f) serving as ash fall and air inlet a plate-like, with the fold-down grate (b) connected closure body (g) is used, which in the Ti.efstlage .des folding grate (b) covers the opening (f) and for the purpose of regulation the air inlet at a greater or lesser distance from the wall opening Locking of the folding grate (b) adjustable in corresponding intermediate positions is.
