Abstract
Description
- This invention relates to a stove, comprising a combustion chamber with at least two closable openings and a flue duct, a controllable damper being provided between the combustion chamber and the flue duct in order to close off the abovementioned duct.
- This invention relates in particular to a see-through stove.
- Atmospheric stoves are available in many types, styles and sizes. A particular form, which is becoming increasingly popular is the see-through stove. Such stoves have at least two closable openings lying opposite each other. This stove is placed in a wall in such a way that the hearth fire is visible on both sides, for example in two adjacent rooms.
- See-through stoves with, for example, two closable openings must be connected to a chimney (flue) which draws very well, for if the user has the fire on with one or two openings not closed off, smoke must not pass through these unclosed openings into the living room. In the closed state (both openings closed off) the chimney then draws much too hard, with the result that the chimney draws the heat out of the appliance. The result is poor combustion and much lower efficiency.
- Since the efficiency of see-through stoves is largely determined by the chimney draught, it is known to provide such stoves with a control damper in order to adjust the air supply and thus increase the efficiency.
- This solution has the disadvantage, however, that the damper has to be opened every time a door is opened. This is often forgotten, with the result that smoke often goes into the living room. Furthermore, in the case of such see-through stoves there is still too much chimney draught when the damper is open and the fire is on with one opening closed off.
- The object of this invention is to provide a stove with better combustion and greater efficiency in all circumstances, irrespective of whether the openings are open or closed.
- The object of the invention is achieved by providing a stove comprising a combustion chamber with at least two closable openings and a flue, a controllable damper being provided between the combustion chamber and the flue, which damper comprises at least two individually controllable damper elements. By dividing the damper it is ensured that the damper can be opened only partially or can be opened fully depending on the number of openings not closed off. This results in better combustion and considerably greater efficiency. In particular, the damper comprises two individually controllable damper elements.
- According to a preferred embodiment of the stove according to the invention, the abovementioned stove comprises a closing means for each opening, each closing means being provided for controlling at least one damper element. The abovementioned closing means is preferably a lifting door, tilting door or revolving door.
- In a particular embodiment of a stove according to this invention each closing means is movable between an open and a closed position, in the closed position of a closing means the respective damper element being provided so that it partially closes off the flue duct. It should be pointed out here that the expression in a closed position of the closing means does not rule out a statutory minimal opening still remaining in order to allow the combustion gases to leave the combustion chamber.
- In a more particular embodiment of the stove according to the invention, when each closing means is in its closed position, the damper elements are provided so that together they close off the abovementioned duct to the maximum permitted extent.
- According to a particularly advantageous embodiment of the stove according to the invention the abovementioned stove comprises setting means for setting the angle of the two damper elements depending on the chimney draught. The setting means preferably comprise a threaded rod that can be screwed in and out.
- The stove according to this invention is preferably a see-through stove.
- In order to explain the features of this invention further and to indicate additional advantages and details of the invention, there now follows a more detailed description of a stove according to the invention. It should be clear that nothing in the description below can be interpreted as a limitation of the protection for this invention applied for in the claims.
- In this description reference is made by means of reference numerals to the appended drawings, in which:
-
Figure 1 is a front view of a see-through stove; -
Figure 2 is a view of the see-through stove shown inFigure 1 along line A - A; and -
Figure 3 is a perspective view of a damper with two controllable damper elements provided in the flue duct of the see-through stove. - This invention relates to a stove (1), in particular a coal-fired or wood-burning stove, comprising a combustion chamber with at least two closable openings and a flue duct (2), a controllable damper (3) being provided between the combustion chamber and the flue duct (2) in order to close off the abovementioned duct (2). The stove according to this invention is characterized in that the abovementioned damper (3) comprises at least two individually controllable damper elements (4, 5).
- The stove (1) shown in
Figure 1 is a see-through stove with two closable openings lying opposite each other. The see-through stove illustrated is provided with two lifting doors (6, 7) for closing off the openings lying opposite each other. - The damper (3) (see
Figures 2 and3 ) comprises two damper elements (4 and 5) which are operated separately by the two lifting doors (6 and 7). In the figures shown the first lifting door (6) will control a first damper element (5), and the second lifting door (7) will control the second damper element (4). The lifting doors are provided with a mechanical transmission (9) for controlling the different damper elements (4, 5). - Since the damper elements (4, 5) are operated individually by two lifting doors (6, 7) functioning independently of each other, when the fire is on with only one lifting door open the flue duct (2) will be only partially closed off by one damper element, with the result that the fire will remain burning more gently.
- When the fire is burning with two lifting doors (6, 7) open, both damper elements (4, 5) will open fully automatically, so that smoke will no longer go into the living room.
- When the fire is burning with two lifting doors (6, 7) closed, both damper elements (4, 5) will also close, thereby closing off the flue duct (2). This will produce a higher temperature in the stove, resulting in better combustion, considerably greater efficiency and much less pollution of the environment, and much less wood or fuel consumption, and the glass lifting doors which make the see-through stove so interesting remain cleaner for much longer.
- The stove according to this invention is furthermore provided with setting means (8) for adjusting the angle of the two damper elements (4, 5) and thereby adjusting the chimney draught depending on the circumstances. The setting means preferably comprise a threaded rod (8) that can be screwed in and out, being pressed down by a small lip of the door when the door closes, thereby making the damper element close at a particular angle depending on the length of the threaded rod (8).
