Abstract
A solid fuel stove (fig 1, a) includes a door (fig 1 b), a handle (fig 1 c) and a window d. The door has a number of holes g. A plate h with holes j is fitted across the holes in the door. The plate is attached to a handle (fig 1 g) which moves in a slot e so that the plate moves from side to side, opening and closing the holes and controlling the amount of air supplied to the stove.
Description
Variable output stove This invention relates to a means to alter the setting for the maximum heat output of a solid fuel burning stove.
When a consumer is choosing to purchase a solid fuel burning stove, one of the deciding factors is the rated heat output of the stove. This is measured in kilowatt hours. The kilowatt hour rating is determined by how quickly the fuel is burnt which is in turn determined by the amount of air which is allowed to enter the combustion chamber via a variable sized aperture. Heat output can be altered by the operator between a maximum and a lower rate by regulating the size of the variable aperture and therefore the amount of air allowed to enter the combustion chamber.
Once a consumer has purchased a stove however, for example with a maximum rated output of 5kWh, they cannot then alter the maximum output should they find they need more heat. This may be desirable if the consumer moves house and finds that the new living room requires a maximum output of say 8kWh. A stove with a variable maximum output would also be helpful for retailers and manufacturers as they would need to stock a fewer number of different models.
To overcome this problem this invention provides a method of altering the maximum output of a solid fuel burning stove. This invention will now be described using the following drawings.
Figure 1 shows a typical wood burning stove (a), with a door (b) comprising of a handle (c) and glass window (d). The air supply to the combustion chamber is usually provided by slots or holes such as those at the top and bottom identified by (g). A plate (not shown) with corresponding holes is positioned behind the holes (g), and can be slid from side to side by handle (f) which slides along slot (e).
Figure 2 shows a view of the rear of the door. Plate (h) locates over the holes (g).
Figure 3 shows a front view of plate (h) so the handle (k) can be seen. The handle fits through slot (e).
Figures 4 and 5 demonstrate how the holes in the plate (j) are in line with the holes in the door (g) which are represented by the dotted line, and how they move out of line when the plate is slid across.
In this example the maximum output of the stove is determined by selecting which way round the plate (h) is fitted. The holes in the plate shown in figures 4, 5 and 6 are not along the centre line but are closer to one edge. In this example if plate (h) is fitted with the holes (j) closer to the lower edge they will line up with the holes (g) in the door. If however plate (h) is removed, rotated through 180 degrees and refitted so the holes (j) are closer to the top edge, even in the open position the holes (g) in the door will still be partially obscured so the maximum amount of air which can pass through them has been reduced, thereby reducing the maximum heat output of the stove.
Figure 7 shows another example of how the maximum heat output of a stove could be altered. In this example one or more of the holes in plate (h) has been threaded. A bolt (I) can be added or removed to alter the number of holes which are obscured to prevent air to pass through.
The sliding plate (h) could also have a screw or screws which could be used to alter the maximum distance of travel and therefore set the desired maximum opening.
Claims (4)
- Claims 1. A solid fuel burning stove with a means to alter the maximum amount of air which can enter the stove for combustion.
- 2. A solid fuel burning stove with a plate with number of holes in it which alters the maximum amount of air which can pass through it depending on which way round it is fitted.
- 3. A solid fuel burning stove as described in claim 2 with more than 1 plate.
- 4. A solid fuel burning stove with a sliding plate to regulate the amount of air which can enter the combustion chamber with means of limiting the distance of travel of the sliding plate so various maximum settings ca n be selected.
