DE3107820A1 - VARIABLE FIREPLACE - Google Patents

Description

The invention relates to a variable fireplace. Nowadays a fireplace is generally made of expanded clay cement and other insulating materials having a cast iron and / or refractory surface. Further grilles and various openings for ventilation are necessary for combustion and also for Collecting the ashes when using solid fuels.

Other chimneys have frames made of steel, cast iron, copper, etc. sheet metal with air spaces for ventilation, through which the air passes and is then distributed in the room to be heated.

The air is heated by the combustion products of the solid fuels that burn on the fire surface. A chimney is completed by an extractor hood that collects the exhaust gases. Outside, the chimneys are _{clad with stone, wood (} copper panels, etc.) to improve the appearance.

In addition, hot water boilers are known, but they are not suitable to be installed in normal living spaces to become. After all, stoves are also known for cooking and as a heat source, but the effect is low when heating several rooms.

The object of the invention is to provide a fireplace that eliminates the above-mentioned disadvantages and for various Purposes can be used.

130062 / 059S

This object is achieved according to the invention by the features specified in the main claim.

Further developments result from the subclaims.

The fireplace according to the invention can be used as an alternative to oil heating of living spaces.

In detail, the following advantages result:

1. The fireplace has an appearance that is completely the same as that of a conventional fireplace.

2. The fireplace has the characteristics of being used as a stove and thus it can be used for cooking purposes as well as being used for heating purposes.

3. The fireplace can be used as a boiler with the appropriate control and regulation devices, whereby the hot water is distributed to radiators, convectors, boilers, etc., which, as usual, are used for domestic heating that is, thermohydraulic techniques are used.

4. The fireplace has a boiler in its frame or frame below the fire surface, as well as one or several combustion chambers for wood, coal, diesel oil, kerosene, gas etc. and the corresponding burners and operating devices.

5. The fireplace has a traditional look but can be used as a stove and boiler at the same time.

The hood is equipped with air locks, registers, extractors and the necessities for the best working of the chimney fitted.

The invention is to be explained below using an exemplary embodiment.

It shows:

Fig. A is a front view of the fireplace,

Fig. B shows a section along the line D-D in Figure A and

FIG. C shows a section along the line E-E in FIG. A.

In FIG. A, the feet are denoted by 1 and the floor on which the chimney stands is denoted by 2. The base plate 3 made of refractory cement is used as the combustion chamber floor. 4 with a drawer for collecting and pulling off the ashes is referred to. Adjustable slots 5 are used to supply air.

The surface 6 contains the combustion chamber at the top and acts as a stove-like cooking surface and as a fireplace surface, bounded by a front wall and by side walls 7.

The extractor hood for collecting the bgases and for forwarding it into the chimney is denoted by 8.

The above reference numerals also appear in FIG. B, with the entry of the combustion air here as well F is designated.

As can be seen from FIG. B, the combustion space 9 is divided by a double wall 10, 11, which forms a water space 12 forms which is closed at the top by a part of the surface 12 and at the bottom by the wall 13.

- 7 - 130062/0596

In a space delimited by the walls 7 and 11, the heat exchangers 15 are arranged, which consist of tubes and through which the flue gases from the combustion chamber 9 flow in space 16. In the illustrated embodiment, the combustion chamber 9 has a removable one Grid 17 is provided, which is designed for the combustion of wood, coal, sawdust, etc. At 19, the and return pipes for heating water generated by the fireplace. The reference number 20 indicates ■ the building wall on and with 21 a cover plate -which is hinged at H-.

The arrow G indicates the directions of movement of the cover plate, which depend on the various possible uses of the Chimney can be determined depending on whether it is used as a fireplace and / or is used as a stove and / or as a boiler.

In Figure C, the heat exchanger tubes 15 are shown again. The metal walls 10, 11, 7, 14 enclose the water in the space 12.

; The cooking or fire surface 6 is made up of movable rings 18

, which can be replaced by a grid around

' To let air or ash through if the surface is considered

• Fire surface, i.e. a normal fireplace, is used.
