The invention relates to a fireplace with an approximately quaderförroiqen Firebox, which is dimensioned for burning several logs about 30 cm (centimeters) long and in the one below a fresh air line opens and from the top a smoke exhaust line goes out and the front side is open and can be closed by a door.

Fireplaces of this type are fed with logs in the firebox, which are burned down, whereby emphasis is placed on the fire - be it through windows in the doors or when the door is open neten doors - to look at.

It is desirable to use other fuels in such chimneys, such as coke and briquettes to burn, but the firebox is not equipped for this.

The object of the invention is to design a chimney of the type mentioned in such a way that coke, coal and briquettes can also be used can be burned with good efficiency.

The invention is characterized in that a filling shaft is provided under the furnace, which has a base area of at least 4 edm (square decimeters), a height of at least 15 cm and extends over 20 to 80 % (percent) of the cross-section of the floor area of the furnace , and that the bottom of the hopper is formed by a grate and that the fresh air line opens below the grate.

It has been shown that coke, coal and briquettes. if they are placed inside the filling chute, they can be burned off with extraordinary efficiency, i.e. with: favorable heat transfer to the surroundings of the chimney, while at the same time the wood fire, which is desirable for consideration, can be operated in the combustion chamber.

The supply of fresh air is used to ignite the filling of the hopper and the smoke outlet duct is open, then it burns experience has shown that the filling shaft is completely precipitated and the combustion chamber fills with burning gases. To it then the burning rate can then be reduced by restricting the smoke exhaust pipe accordingly and / or the fresh air supply line.

It is noteworthy that in this way the fireplace both for Burning off of coke, coal and charged in the hopper Briquettes or for. Burning of logs placed in the furnace and for burning coke, coal and briquettes in the hopper and logs in the firebox is suitable at the same time, firing with coke, coal and briquettes can be operated with a favorable heat yield.

The invention will now be explained in more detail with reference to the accompanying drawing.

In the drawing shows:

Figure 1 a Ka: nineinsatz in cross section and FIG. 2 shows the view according to arrow II from FIG. 1.

In the drawing, 1 denotes a cuboid furnace which is open at the front and can be closed by a double-leaf door 2. The combustion chamber 1 can be viewed through glass inserts and 4 in the door leaves. At the Eoden 5 of the furnace 1 closes a filling shaft 6, which extends below the furnace 1 and is closed at the bottom by an inserted grate 7. Below the grate 7 there is an ash tray 8 open to the grate for collecting cer ash. The ash tray 8 can be pulled out towards the front in the direction of the arrow 9. Below the ash pan, the bottom 11 is open, so that fresh air can flow in there in the direction of the arrow 12, which finds access past the ash pan ö through the supply air space 13 and the grate 7 into the filling chute 6 and from there into the combustion chamber 1.

15 with an upwardly tapering connector is referred to, which extends below over the entire width of the combustion chamber 1 and extends upwards approximately on the cross section a smoke extraction line 16 connected there tapers. Within this connection piece 15 deflection plates 17 are arranged, which are a labyrinth-like obstacle for the in Direction of arrow 19 form upwardly flowing smoke gases. The smoke exhaust pipe 16 is through an adjustable throttle valve 20 apparently and closable except for a narrow gap 21.

The walls of the fireplace are made of steel. The side walls and the rear wall and the bottom surface of the furnace 1 and the side walls of the hopper 6 are lined with chamotte 22.

Three different operating modes are possible: The first operating mode only burns wood that is in The shape of logs 23 is piled on the floor 5 of the furnace 1. The logs are about 30 cm long and span the width of the upper opening 25 of the hopper, indicated by the double arrow 24. When doing individual logs If you fall into the hopper, this is not a disadvantage. But you can, to make sure that the logs, so that the fire is clearly visible, remain within the combustion chamber 1 and do not fall into the hopper, there Support grate 26 - as indicated by dashed lines - set that spans the opening 25 and a support for the logs 23 forms.

In the second operating mode, ice is burned in wood, it is only coke, coal or briquettes 27 which are filled into the feed chute 6 are burned.

In the third operating mode, coke, coal, briquettes 27 are filled into the hopper 6 and logs 23 are burned, which are piled up in the combustion chamber 1.

In the first one mode of operation, fire is essentially used Consideration provided, in the second operating mode the fire is essentially only used for heating and in the third Operating mode, the fire is used for heating and viewing.

To utilize and dissipate the heat developed in the fire serve lateral air circulation channels 30, 31, which are open at the bottom and top and are flushed with room air and put in good heat exchange contact with combustion chamber 1.

The dimensions of the illustrated embodiment according to the double arrows shown are given in the table below. In addition, dimensions of further exemplary embodiments are specified in this table, which differ essentially only in terms of these dimensions from the exemplary embodiment shown.

The cross-section of the opening 25 extends in all exemplary embodiments over 20 to 50% of the bottom surface 5 of the combustion chamber 1. The total filling volume of the filling shaft 6 is approximately 8 to 20% of the filling volume of the cuboid part of the combustion chamber 1, i.e. up to the height of the dash-dotted line 33.
