Abstract

Chimney furnace (1) has a fireplace (2) which is covered by a flue (5) merging into a chimney (6). The flue and the chimney are designed as double-walled to the border of a thermal insulating layer (10,14). Inner wall (9,13) of the flue and the chimney is coated with a thermal insulating layer whereby an air layer (12,18) is provided between the insulating layer and an interspaced outer wall (11,17) of flue or chimney.

Description

The Invention relates to a stove, grill oven or the like, having a hearth, which passes from one into a chimney Esse covered becomes.

Stoves are known and proven in various embodiments. For example, in DE 20 2004 018 641 U1 . DE 20 2005 004 822 U1 . DE 20 2006 004 196 U1 or DE 20 2006 004 202 U1 , find such ovens in addition to the original purpose of heat generation on terraces, balconies or the like usually for a barbecue use. For this purpose, a refractory room with shots for barbecue grills, skewers or the like is provided regularly.

It are such stoves building relatively low, so that the hearth covering Eat that regularly into one Fireplace passes, also very low above a floor is arranged.

The Esse and the fireplace, especially if the fireplace, for example. through a glass door is completed, due to their design dangerously hot. This is basically the Danger to persons, in the hot Esse or on the hot To burn the fireplace. This is true both when grilling for a Operator as well especially for children.

One Another, typical disadvantage of the known stoves is the threat to the Surroundings of the stove by flying sparks when, for example, on the fireplace burns a wood fire, its deduction on the Ese and the fireplace mostly throughout, without obstacles to the outdoors.

In front In this technical background, it is the object of the invention to a stove of the type mentioned above available in which the operational safety is increased.

Is solved This technical problem with a stove, grill oven or The like, having a hearth, from one to one Passing fireplace Esse covered is according to the claim 1 by the measures, that the dining room and the fireplace double-walled underneath at least a thermal insulating layer are formed.

By the thermal insulation of the inner walls of the butt or the fireplace It is ensured that no one on these hot, inner walls can burn. Although the outer wall is regularly used the butt or the fireplace are warm, but is regularly the thermal insulating layer be formed so that on external, a touch barely accessible walls there is no risk of burns.

It can be provided that each have an inner wall of the food and the fireplace is covered with a thermal insulating layer and that between the insulating layer and a spaced outer wall the esse or the fireplace an air layer is provided.

It It is known that air layers have comparatively good insulation properties exhibit. Especially in connection with the thermal insulation layer on the inner wall of the butt or the fireplace is a sufficient achieved thermal insulation, with still reasonable dimensions, which are in the centimeter range.

In a first alternative, the inner wall with a foamed insulating layer be occupied. Such a foamed insulating layer will become in an excellent way to the geometry of the inner wall of the Esse or the chimney. In particular, welds, sharp bends, Edges or the like are isolated in a simple way so. When However, it can be perceived disadvantageously that the strength of this frothed Insulating layer is not really predictable.

The same can be achieved with a poured insulating layer on top inner walls poured or can be created as a separate mold. For one Casting one thermally insulating layer suitable materials are mostly mineral Components, such as mica schist on.

In a further embodiment the inner wall can be covered with thermally insulating mats, for example, with mats of a mineral rock wool, if necessary also in several layers.

Other Materials for the formation of the thermal insulating layer are nevertheless possible and available in the prior art. The skilled person will choose the most suitable thermal insulation which can be adapted to the geometry of the meat and the fireplace and ensures adequate thermal insulation.

Around To prevent the sparking can also be provided that the Closed chimney from a spike-preventing tower is. Such sparking baskets, covers, caps or other head pipes or chimney cowls are also in the state known in the art.

The stove according to the invention will be explained in more detail with reference to the drawing, the only 1 schematically shows a front view of an embodiment.

The stove 1 according to 1 has a fireplace 2 on the rust-resistant plates or the like regularly allows the burning of different fuel such as logs or charcoal. The burn-off conveniently falls down into a drawer-like ash pan for easy disposal 3 ,

Above the hearth 2 is a refractory room 4 provided, which may be provided for example with brackets for grill grates, skewers or the like for a barbecue.

Should the stove 1 only serve to generate heat according to the invention, is advantageously a front opening of the refractory space 4 closed, for example by heat-resistant glasses or the like.

The fireplace 2 and the firebox 4 are from a food 5 Covered, the funnel-like or bell-shaped formed smoke, ash particles and the like of the burns and a fireplace 6 discharges into the environment.

The chimney 6 becomes from a fly-preventing essay 7 still covered, which may be formed, for example, in the manner of a known spark arrester basket or the like.

To the risk of burning on a hot food 5 or by a hot fireplace 6 to meet, are the food 5 and the fireplace 6 double-walled formed enclosing at least one thermal insulation layer.

In 1 in the plane of symmetry 8th Separate left half of the picture carries an inner, the eating 5 and the fireplace 6 inside wall 9 a thermal insulation layer 10 on the inner wall 9 foamed, indicated by the irregular surface of the insulating layer 10 , Such a foamed insulating layer 10 is with the inner wall 9 perfectly arrest and follow its form completely unproblematic.

Between the thermal insulation layer 10 and an outer wall 11 an air layer remains 12 , due to the irregular surface of the thermal insulation layer 9 of varying strength.

This execution comparable is a directly applied to the inner wall, thermally insulating cast layer.

In the right half of the picture 1 is an inner wall 13 with a thermal insulation layer 14 made of mats 15 . 16 busy. Such mats, for example of a mineral nature, also conform to the geometry of the inner wall 13 good enough. These mats can be fixed by brackets, glue or the like.

Also in this embodiment is the outer wall 17 again through a layer of air 18 from the thermal insulation layer 14 spaced.

Comparable the laying of mostly flexible mats is a hang up a separately molded, in particular cast insulating layer.

The outer walls 5 . 17 can have suitable spacers on the substantially bearing, inner walls 9 . 13 be held. Such spacers should optionally be thermally insulated.

The extra weight due to the thermal insulation layers 10 . 14 or outer walls 11 . 17 plays only a minor role, since such stoves 1 regularly on rolls 19 . 20 are movable.
