Description

Description:

The invention relates to a wood-burning stove that is free-standing or set up in a mix or walled in as an open rabbit or conventional solid fuel stove with wood and / or coal can be operated, with a furnace and Ascherauni, a single or multi-part combustion chamber door, also designed as a viewing window door, an ash chamber door, a furnace floor, a food device, an exhaust gas deflector and a Exhaust connection nozzle.

Long-life burners are known in which the automatically regulated burn-up already occurs has been satisfactorily sailed. These ovens have a high efficiency and a Endurance burn for many hours with even heat output. As disadvantageous the missing katainfire effect is often felt.

Open fireplaces have this desired comfort effect, which is evident the observation of the crackling fire or the play of flames and that as pleasant perceived radiant heat.

There are single and multi-sided open chimneys known. It is also known
that one to influence the burn-up for safety reasons or because of
possible nuisance caused by smell as well as other reasons these 'chimneys
mi · - carries out different types of doors. The large combustion chamber with a flat fire bottom in connection with a non-targeted combustion; sluftführur.i;
and the resulting large excess of combustion air leads to the
lower. Efficiency of open chimneys, which are hardly more than 30 λ (see
"Heating and Warning", brochure of the LUihrkohlen AU, page 215).

The comfort that an open kaolin undoubtedly offers is therefore one

unsatisfactory heating technology. Such fireplaces are therefore suitable

only as additional heating or during the transition period. i

With fireplace chimneys, that is, stove-like chimneys that can be set up freely or in wipes

or walled in and connected to every chimney, like vfi

they are common in the USA and in Germany, especially from the Scandinavian £

Countries are known, better efficiencies can be achieved than with open '§

Achieve chimneys. Although some of them already come with automatic combustion air ^Ί

regulators are equipped (G 7S0ß 996.0), a controlled burn-up is with these ;;

Fireplace stoves are not possible, as not all requirements (e sealed housing, '.}}

specifically directed combustion air, grate- ^ designed according to the endurance fire

basket, fire and ash wood) are present at the same time. For example, at t!

a comparable oven (brochure WOODSTOVE-DIRüCTORY, edition 1932, page 188) t \ already the airtight construction and the use of a bi-metal thermostat
addressed, while the other requirements for a controlled combustion are missing.

To establish certain minimum requirements for those that are installed more frequently
A standard was created for wood-burning stoves with manual control (currently DIM 18 891
which already makes a statement about the permanent band and the minimum efficiency
specifies. However, there is only limited use of flat firing on the level firebox
the possibility to direct the fuel to a certain room (certain grate area)
limit. Since here the combustion air both from below and from above
reaches fuel lying on the grate or on an additional firebock,
the combustion air is not supplied in a targeted manner.

The invention is therefore based on the object of providing a Knminofen of the initially described type in such a way that it largely eliminates the annuities of a open rabbit and has the advantages of a long-life stove and thus as a full fireplace can be used economically.

The invention solves the problem because. ^r 3 ii; i Feuerrau'.nboden dos firebox sealed against the ingress of uncontrolled combustion air a recessed, trough-shaped fuel chamber in the form of a flat grate basket is provided, to which a grate device is connected to the lower opening.

In the large-area fireplace stoves that are not regulated at all or that are regulated by land Firebox floor with the plan grate became one of the heating power or the t Endurance fire correspondingly large volume; aigc fire brigade (flat Uost basket) provided and the ash or fire room except for the one controlled by the automatic combustion air regulator Air inlet opening completely tight against uncontrolled external air. Due to the precisely coordinated individual measures (tightly connected furnace parts, tightly closing furnace and ashtray doors, from a food facility limited firebox with recessed cr fuel brown, targeted Combustion air duct, automatic combustion air regulator) was first a Chimney stove created, which as a fireplace has the convenience of an open Chimney and the good heating properties of a long-life stove with high Has a degree of efficiency and is therefore a fully-fledged heating system.

The invention is described below - for example with reference to the drawing; in this shows:

Figure 1 is a half-sectioned front view of an inventive Fireplace,

FIG. 2 shows a section along the line H-II in FIG. 1.

According to the drawing, one of them is roughly the same size as an open fireplace the furnace housing (11) a furnace (12) with a furnace floor (13) and one therein recessed trough-shaped fuel space or a flat grate basket (14) provided. The height of the grate basket (14) according to the invention, which expediently expands in the shape of a funnel towards the top of the furnace floor (13), is approximately 1/2 to 1/10, but preferably 1/6 the width of the grate basket. For particularly good combustion or heating properties, a ratio is recommended for the grate dimensions of width: depth: height like 6: 4: 1.

The grate basket (14) is down to the Asclioraum (16) through a grate device (15) limited.

The circumferential below Stoßstclle (17) in a. \ 'Ut (18) of the bottom (1 ^(J) walls employed (20) as well as the upper StoDstelle (17') of the Ofanwünde (20 ^χ to the furnace upper part (21) towards The fire ring floor (13) is also sealed against the furnace walls (20) at (Ul) and the grate basket (IA) in the fire floor (13) along the circumferential floor area (31 ¹ ). Also the Aschurau ;; The door (22) and the relatively wide combustion chamber door (23), shown in two parts, can be closed tightly so that no combustion air can enter uncontrolled. When the doors are closed, the combustion air only gets through the air inlet opening controlled by the automatic combustion air regulator (24) ( 25) over the guide plates (26) from below, i.e. in a targeted and metered manner, to the fuel lying on the grate device (15).

When the ash compartment door (22) is open, the ash pan in the ash compartment (16) can (27) can be removed from the front. When the combustion chamber door (23) is open, the stove can operated like an open fireplace. The stove has closed Firebox doors (23) endurance burning properties. If the combustion chamber doors (23) as If viewing windows are executed, the rabbit fire effect is also set here.

The combustion chamber (12) opens up into a horizontally or vertically arranged one Exhaust connection piece (28). The inner furnace or the inner furnace housing (11) is at Free-standing stoves from a; n visually appealing jacket - e.g. B. off enamelled cast tiles, ceramic tiles, in the form of cast iron stove plates or similar.

When installed in tuschen, this jacket is preferably made of galvanized sheet steel and thus forms a convection shaft (32) around the inner furnace.
