Definitions
- the invention relates to motor-driven chimney draft systems used for assisting or supplementing the thermally induced draft in a chimney.
- Motor-driven chimney draft systems are used when the thermally induced chimney draft is insufficient. This is the case when the temperature in the chimney has not yet reached a level where the thermally induced draft is sufficient for a proper combustion and operation of the system.
- a motor-driven chimney draft system supplements an insufficient thermally induced draft, and the forced draft increases the flow of flue gases which are removed from a furnace, a stove or other fireplace, which in turn draws fresh air into the furnace to support the combustion. After some time the combustion may have reached a stage where the thermally induced draft is sufficient and the motor-driven chimney draft system can be deactivated.
- Flue gases can be very hot, and although some cooling will take place on their way from the fireplace to the flue gas outlet of the chimney, the flue gases can still be hot when leaving the flue gas outlet of the chimney.
- Chimney draft system including its motor must therefore be constructed to operate at elevated temperatures caused by the flue gases.
- Document CN281928Y discloses a motor-driven chimney draft system according to the preamble of claim 1.
- motor-driven chimney draft systems add as little as possible flow resistance to the flow path of flue gases. It is also desirable that the motor is protected from excessive heating by the flue gases so that no arrangements, or only cost-effective arrangements, need be taken for preventing excessive heating of the motor.
- the invention provides a motor-driven chimney draft system according to claim 1.
- the flue gas compartment preferably has a cover which can be opened to allow access to the flue gas compartment, e.g. for cleaning by a chimney sweep or inspection, service and maintenance.
- a motor compartment housing the motor is situated laterally relative to the flow direction and separated from the flow of flue gases by a separating wall extending parallel to the flow direction with the motor shaft extending through the separating wall in a direction transverse to the flow direction.
- each of the separating wall of the flue gas compartment and the separating wall of the motor compartment extends parallel to the flow direction of flue gases, and they are arranged facing each other so as to define an air space therebetween, where the air space has openings allowing ambient air to flow through the air space.
- the distance between the separating walls reduces heat transfer from the flue gas compartment to the motor compartment, and access by the ambient air to the space will give rise to thermally induced convection, in particular when the space is oriented vertically and is open upwardly.
- the figures show a motor-driven chimney draft system for mounting on top of a chimney leading flue gases from a fireplace such as a stove.
- the system has a generally cylindrical shape.
- FIGS 2 and 4 are shown a fitting device 10 at the bottom of the system which is used for fitting the system to the top of a chimney so that a flue gas inlet 11 of the system can receive a flow 12 of flue gases from the chimney.
- the flow of flue gases have a flow direction indicated by arrows which is the same flow direction as in in the chimney.
- a motor compartment 14 of the system houses a motor 13 which has a motor shaft 15 carrying an impeller 16 with impeller blades 17, in this embodiment six impeller blades 17, for driving the received flow of flue gases out through a flue gas outlet 18 at the top of the system.
- the motor compartment 14 is situated laterally relative to the flow direction of flue gases and is separated from the flow of flue gases by two separating walls 19, 20 each extending parallel to the flow direction of flue gases.
- the motor shaft 15 extends through the separating walls 19, 20 in the horizontal direction, i.e. transverse to the flow direction of flue gases.
- a screen 21 is mounted on the separating wall 19 on the upstream side of the impeller (here: below the impeller) and extends from the separating wall 19 on the upstream side of the impeller 16 and has a portion which extends in the downstream direction (here: upward) on the suction side of the impeller 16 and covers a peripheral portion of some of the impeller blades 17 and leaves a central suction zone uncovered.
- the impeller 16 When the impeller 16 is driven in rotation by the motor 13 the impeller blades 17 will drive flue gases in all radial directions away from the shaft 15, and a central zone will act as a suction zone and suck flue gases in the flue gas compartment 27 towards the suction zone.
- the screen 21 blocks a radial flow path from the impeller 16 in the upstream direction (here: downward) towards the flue gas inlet 11, and the screen 21 thereby prevents flue gases and air from being blown out through the flue gas inlet 11, i.e. in the undesired reverse direction. Flue gases which are sucked toward the central suction zone will consequently be blown in the downstream direction (here: upward) and out through the flue gas outlet 18 as indicated by an arrow at the flue gas outlet 18.
- the impeller 16 will also cause a vortex with a rotational movement of the flue gases in the direction of rotation of the impeller.
- the screen can therefore advantageously be asymmetric and have a unilateral portion extending in the downstream direction as indicated by a dashed line 21'.
- the portion of flue gases between the separating wall 19 of the flue gas compartment 27 and the lateral portion 21' of the screen 21 are moving in the desired downstream direction, and the lateral portion 21' of the screen 21 separates this downstream flowing portion of the flue gases from the flue gases in the remaining part of the flue gas compartment whereby mixing is prevented or at least reduced with the effect that the efficiency of the system is further increased.
- an optional rain screen 22 shown in dashed line can be arranged at the top wall of the system and extending downward into the flue gas compartment 27. If present, the lower edge of the rain screen 22 will preferably be closer to the separating wall 19 than is the upper edge of the screen 21, so that water dripping from the rain screen 22 will be caught by the screen 21 and can be drained from the system as indicated by arrows 23 in figure 4 .
- the size and shape of the rain screen 22 shown in figures 2 and 4 are only for illustrative purposes.
- the top wall 28 of the flue gas compartment 27 is hinged and can be opened to give access to for inspection and easy cleaning by a chimney sweep.
- the motor compartment 14 is separated from the flue gas compartment 27 by a vertical air space 24 defined by the separating walls 19, 20 which are at a distance from each other.
- the air space 24 is closed downwardly whereby flue gases cannot enter into the air space 24, and the air space 24 has openings to the ambient at the two opposite vertical sides or, preferably, also upwardly i.e. at all three of the other sides allowing ambient air to flow through the air space 24.
- Flue gases in the flue gas compartment 27 will heat the separating wall 19 and air in the air space 24 which is in contact with the separating wall 19 will be heated, which will cause thermally induced convection whereby ambient air will be drawn into the air space 24 from the sides as indicated by arrows 25 in figures 1 and 3 and leave the air space 24 in an upward direction as indicated by arrow 26 in figure 2 .
- the air space 24 is oriented vertically which enhances thermally induced convection.
- the distance between the separating walls 19, 20 will in itself reduce heat transfer from the flue gas compartment 27 to the motor compartment 14, and the thermally induced convection will have a cooling effect. Furthermore, wind will have access to the air space 24 and provide cooling. Finally, because the flue gas outlet 18 and the upper opening of the air space 24 are close to each other over almost the entire diameter of the system, the flue gas flow out of the flue gas outlet 18 will also draw air out through the upper opening of the air space 24.
- the motor shaft can carry an impeller in the air space 24 for assisting the thermally induced convection.

Description
- The invention relates to motor-driven chimney draft systems used for assisting or supplementing the thermally induced draft in a chimney.
- Motor-driven chimney draft systems are used when the thermally induced chimney draft is insufficient. This is the case when the temperature in the chimney has not yet reached a level where the thermally induced draft is sufficient for a proper combustion and operation of the system. A motor-driven chimney draft system supplements an insufficient thermally induced draft, and the forced draft increases the flow of flue gases which are removed from a furnace, a stove or other fireplace, which in turn draws fresh air into the furnace to support the combustion. After some time the combustion may have reached a stage where the thermally induced draft is sufficient and the motor-driven chimney draft system can be deactivated.
- In existing motor-driven chimney draft systems the flue gases are forced to change flow direction which increases the flow resistance, which is undesirable.
- Flue gases can be very hot, and although some cooling will take place on their way from the fireplace to the flue gas outlet of the chimney, the flue gases can still be hot when leaving the flue gas outlet of the chimney. Chimney draft system including its motor must therefore be constructed to operate at elevated temperatures caused by the flue gases.
- Document
CN281928Y discloses a motor-driven chimney draft system according to the preamble of claim 1. - It is desirable that motor-driven chimney draft systems add as little as possible flow resistance to the flow path of flue gases. It is also desirable that the motor is protected from excessive heating by the flue gases so that no arrangements, or only cost-effective arrangements, need be taken for preventing excessive heating of the motor.
- The invention provides a motor-driven chimney draft system according to claim 1.
- With this structure the flow direction of the flue gases received from a chimney is maintained with a minimal disturbance also when the motor-driven impeller is inactive, and the motor-driven chimney draft system therefore exhibits a minimal flow resistance to the flue gases.
- The flue gas compartment preferably has a cover which can be opened to allow access to the flue gas compartment, e.g. for cleaning by a chimney sweep or inspection, service and maintenance.
- Preferably, a motor compartment housing the motor is situated laterally relative to the flow direction and separated from the flow of flue gases by a separating wall extending parallel to the flow direction with the motor shaft extending through the separating wall in a direction transverse to the flow direction.
- Advantageously, each of the separating wall of the flue gas compartment and the separating wall of the motor compartment extends parallel to the flow direction of flue gases, and they are arranged facing each other so as to define an air space therebetween, where the air space has openings allowing ambient air to flow through the air space. The distance between the separating walls reduces heat transfer from the flue gas compartment to the motor compartment, and access by the ambient air to the space will give rise to thermally induced convection, in particular when the space is oriented vertically and is open upwardly.

Figure 3 corresponds tofigure 1 ; -
Figure 4 is a vertical section through the chimney draft system infigure 3 taken along the line B-B; and -
Figure 5 is a perspective view of the chimney draft system infigures 1-4 . - The figures show a motor-driven chimney draft system for mounting on top of a chimney leading flue gases from a fireplace such as a stove. In the shown embodiment the system has a generally cylindrical shape.
- In
figures 2 and4 are shown afitting device 10 at the bottom of the system which is used for fitting the system to the top of a chimney so that aflue gas inlet 11 of the system can receive aflow 12 of flue gases from the chimney. The flow of flue gases have a flow direction indicated by arrows which is the same flow direction as in in the chimney. A motor compartment 14 of the system houses amotor 13 which has amotor shaft 15 carrying animpeller 16 withimpeller blades 17, in this embodiment siximpeller blades 17, for driving the received flow of flue gases out through aflue gas outlet 18 at the top of the system. As shown, the motor compartment 14 is situated laterally relative to the flow direction of flue gases and is separated from the flow of flue gases by two separatingwalls motor shaft 15 extends through theseparating walls impeller 16 is driven by themotor 13 theimpeller blades 17 will expel the flue gases in radial directions relative to the impeller in a radial direction of the impeller, and flue gases will be sucked by theimpeller 16 in its axial direction as indicated by a curved arrow. - A
screen 21 is mounted on the separatingwall 19 on the upstream side of the impeller (here: below the impeller) and extends from theseparating wall 19 on the upstream side of theimpeller 16 and has a portion which extends in the downstream direction (here: upward) on the suction side of theimpeller 16 and covers a peripheral portion of some of theimpeller blades 17 and leaves a central suction zone uncovered. - When the
impeller 16 is driven in rotation by themotor 13 theimpeller blades 17 will drive flue gases in all radial directions away from theshaft 15, and a central zone will act as a suction zone and suck flue gases in theflue gas compartment 27 towards the suction zone. Thescreen 21 blocks a radial flow path from theimpeller 16 in the upstream direction (here: downward) towards theflue gas inlet 11, and thescreen 21 thereby prevents flue gases and air from being blown out through theflue gas inlet 11, i.e. in the undesired reverse direction. Flue gases which are sucked toward the central suction zone will consequently be blown in the downstream direction (here: upward) and out through theflue gas outlet 18 as indicated by an arrow at theflue gas outlet 18. - The
impeller 16 will also cause a vortex with a rotational movement of the flue gases in the direction of rotation of the impeller. The screen can therefore advantageously be asymmetric and have a unilateral portion extending in the downstream direction as indicated by a dashed line 21'. The portion of flue gases between theseparating wall 19 of theflue gas compartment 27 and the lateral portion 21' of thescreen 21 are moving in the desired downstream direction, and the lateral portion 21' of thescreen 21 separates this downstream flowing portion of the flue gases from the flue gases in the remaining part of the flue gas compartment whereby mixing is prevented or at least reduced with the effect that the efficiency of the system is further increased. - In a typical situation of use the
flue gas outlet 18 faces upward and in order to prevent rain entering the system through theflue gas outlet 18 from reaching the chimney through theflue gas inlet 11 anoptional rain screen 22 shown in dashed line can be arranged at the top wall of the system and extending downward into theflue gas compartment 27. If present, the lower edge of therain screen 22 will preferably be closer to the separatingwall 19 than is the upper edge of thescreen 21, so that water dripping from therain screen 22 will be caught by thescreen 21 and can be drained from the system as indicated byarrows 23 infigure 4 . The size and shape of therain screen 22 shown infigures 2 and4 are only for illustrative purposes. - Since the flue gas inlet 11 and the flue gas
flue gas outlet 18 are substantially aligned with no or negligible changes in direction or sharp edges that would increase the flow path resistance. Therefore, when themotor 13 is inactive the system will have only negligible influence on the flow. - The
top wall 28 of theflue gas compartment 27 is hinged and can be opened to give access to for inspection and easy cleaning by a chimney sweep. - The motor compartment 14 is separated from the
flue gas compartment 27 by avertical air space 24 defined by the separatingwalls air space 24 is closed downwardly whereby flue gases cannot enter into theair space 24, and theair space 24 has openings to the ambient at the two opposite vertical sides or, preferably, also upwardly i.e. at all three of the other sides allowing ambient air to flow through theair space 24. - Flue gases in the
flue gas compartment 27 will heat the separatingwall 19 and air in theair space 24 which is in contact with the separatingwall 19 will be heated, which will cause thermally induced convection whereby ambient air will be drawn into theair space 24 from the sides as indicated byarrows 25 infigures 1 and3 and leave theair space 24 in an upward direction as indicated byarrow 26 infigure 2 . In the shown typical situation of use theair space 24 is oriented vertically which enhances thermally induced convection. - The distance between the separating
walls flue gas compartment 27 to the motor compartment 14, and the thermally induced convection will have a cooling effect. Furthermore, wind will have access to theair space 24 and provide cooling. Finally, because theflue gas outlet 18 and the upper opening of theair space 24 are close to each other over almost the entire diameter of the system, the flue gas flow out of theflue gas outlet 18 will also draw air out through the upper opening of theair space 24. If desired, the motor shaft can carry an impeller in theair space 24 for assisting the thermally induced convection.
