MULTIFUNCTIONAL OVEN - UGN MED FLERA ANVÄNDNINGSMÖJLIGHETER

The invention relates to the combination of the following fireplaces into the same oven structure: single and continuously heated baking oven, open and reserve fireplace, cold and hot smoking oven and hob.

It is already known in combination as a baking oven and a fireplace baking oven. By placing all the fireplaces of the invention in the apartment with known structures, they become an expensive and large building complex. The multifunction oven according to the invention can be assembled on site from prefabricated refractory elements, which superimpose two fireboxes and a cold smoking room, as well as a smoke duct system and the following applications: single and continuous heating oven, open and reserve fireplace, cold and heating room. By combining the above-mentioned fireplaces into the same structure according to the invention, multiple savings in room space and construction costs are achieved, as well as cold and warm smoking of fish and meat as a new use. The characteristic features of the invention appear from the claims.

The invention will now be described with reference to the accompanying drawing, in which Figure 1 shows a multifunction oven in vertical cross-section, Figure 2 shows a section taken along line II-II in Figure 1. In the drawings, reference numeral 1 denotes the lowest firebox of the oven, from which the flue gases are led through the opening 2 either to heat the hob first in the flue 3 and further down the flue 8 through the chimney. Reference numeral 9 denotes an element which acts as a cover for the lower firebox flue and a grate for the upper firebox 10, and a hob / flue 3 as an opening hob 11. Reference numeral 12 denotes elements forming the walls of the upper firebox and at the same time rear flue ducts together with outer surface elements 14 The ash is dropped through the opening 15 into the ash box 16. The number 17 is the smoke oven door and 18 and 19 are the hearth doors. Number 20 is the ashtray door.

As an open fireplace, the multifunction stove is used by burning wood on the hob level with the shutter 7 open and as a storage fireplace by keeping the fire in the lowest firebox and opening the flue 3 and shutter 7. The hob in the smoke opening 3 is heated from the lowest firebox and the flue gases cooled in the smoke ducts are cold smoked in the smoking space, e.g. meat and fish. The product to be cooked in hot smoking is placed in the upper firebox, e.g. on top of the grilles, the mouthpiece is closed, the shutter is opened and the hob is lifted over the smoke opening 3 and then a small fire is kept in the lowest firebox during smoking. The disposable oven is always obtained from the lowest firebox after the wood has been burned there. The continuously heated oven comes from the top firebox with its mouthpieces closed and the hob in place, as well as the damper closed and holding the fire in the lowest firebox. The multi-purpose furnace can be made partly of metal and / or refractory aggregates, as well as of solid construction. In view of the heat storage capacity, it is better for the furnace to be bulky and to be assembled from the sub-elements at the construction site for transport and transport.

Claims (3)

3,65324 A multifunctional furnace consisting of both overlapping furnaces (1,10) and a cold smoking furnace (5) and a flue (4) assembled from refractory elements, characterized in that the two overlapping furnaces (1,10) operate both independently and together to give the following operating characteristics: single and continuous heating oven, open and storage fireplace, cold and hot smoke oven, hob so that the flue gases of the lowest firebox (1) are directed to either the flue (4) between the upper firebox (10) and the external elements (14) or through a smoke opening (3) connecting the fireboxes and provided with a shutter vertically through the upper firebox (10) and that the walls (21) descend from the grate level (11) of the uppermost firebox (10) between the lower firebox (1) and the outer elements (14) (4), as well as a side-facing barrier as the flue gases flow through the smoke opening (3) connecting the fireboxes. Multifunction oven according to Claim 1, characterized in that the flue opening (3) connecting the two overlapping furnaces is provided for closing by a hob or the like, and by closing and opening this opening the flow direction of the flue gases rising from the lowest furnace (1) is changed. Furnace according to Claim 1 or 2, characterized in that the flue gases from the lower firebox (1) are directed to the smoke furnace (5), first cooling them in the flue ducts (4) of the furnace.
