Abstract

Fireplace insert and fireplace stove containing a combustion chamber (1), a door (2), an outer convection jacket (3), wherein an over-door ventilation flap (5) is pivotally mounted in an over-door space, the ventilation flap (5) enabling regulated flow of heated air in the over-door space.

Description

    Technical Field
  • Technical solution concerns a fireplace insert and a fireplace stove with an outer convection jacket for solid fuel with a device for ventilation of an over-door space.
    • Background Art
  • In fireplace inserts and fireplace stoves with an outer convection jacket and an unventilated over-door space (Fig. 1), local overheating of surrounding parts of the door construction, of parts of the combustion chamber and of parts of the convection jacket occurs in this unventilated space. This results in bringing thermal tensions into construction of the heating body and thereby also in increasing the danger of damaging of some parts.
  • In case the over-door space is ventilated by a permanent slot (Fig. 2), there is a possibility of sucking smoke while the door is opened, and thereby intruding the smoke to a heated space, what is also undesirable.
  • There is a particularly strong need to solve these deficiencies in heating devices of larger dimensions where the ratio of door breadth (B) and door height (H) is higher than 1.5 (B/H)>1.5).
  • The objective of the technical solution is to eliminate mentioned deficiencies and improve abovementioned utility parameters with the emphasis on user comfort.
    • Disclosure of the Invention
  • Mentioned deficiencies are considerably eliminated by a fireplace insert and a fireplace stove with an outer convection jacket for solid fuel with a device for ventilation of an over-door space, containing a combustion chamber, the door, the outer convection jacket, and the device for ventilation of the over-door space according to this technical solution, the nature of which is that an over-door ventilation flap is pivotally mounted in the over-door space, the ventilation flap enables regulated flow of heated air in the over-door space.
  • It is preferable, if movement of the over-door ventilation flap is controlled by the movement of the door, so that the ventilation flap is interconnected with the door by means of a gearing, wherein the movement of the ventilation flap from an open position to a closed position is ensured by the movement of the door from a closed position to an open position and the movement of the ventilation flap from a closed position to an open position is ensured by the movement of the door from an open position to a closed position.
  • The advantage of this technical solution is that it enables ventilation of the over-door space and also prevents the possibility of intrusion of combustion products through the ventilated space to the heated space. By mounting the over-door ventilation flap to the over-door space, the convection heat transfer into the heated air is also increased in comparison with the construction with the unventilated over-door space.
  • The moving over-door ventilation flap enables regulated air flow in the over-door space between the combustion chamber and the convection jacket.
    • Overview of Figures in Drawings
  • The state of the art is explained in more detail in Figures 1 and 2, in which:
    • Fig. 1
    shows in a simplified manner the cross section of the heating body with the unventilated over-door space, in which there are the combustion chamber (1), the door (2) and the outer convection jacket (3) with shown unventilated heated zone (4).
    Fig. 2
    shows in a simplified manner the cross section of the heating body with the over-door space permanently ventilated through the slot (X).
    Fig. 3
    shows in a simplified manner the cross section of the heating body with the mounted ventilation flap (5)
    Fig. 4
    shows in a simplified manner the detail of one alternative of interconnection of the movement of the door (2) with the movement of the ventilation flap (5) by means of the lever gearing (6)
    Example of Embodiment of the Technical Solution Example 1
  • The fireplace insert according to Figures 3 and 4 containing the combustion chamber (1), the door (2) and the outer convection jacket (3) was equipped with the ventilation flap (5), which moves pivotally from the first terminal position - open (Fig. 4, solid line) to the second terminal position - closed (Fig. 4, broken line) and enables regulated air flow in the over-door space between the combustion chamber (1) and the convection jacket (3),
  • The movement of the ventilation flap (5) is derived from the movement of the door (2) by means of the lever gearing (6), the door (2) in this described case moves sliding vertically in the direction of arrows.
  • After door (2) lifting, i.e. door (2) opening, the lever gearing (6) is disburdened, whereby enabling the ventilation flap (5) to move by its own weight to a position - closed, and thereby interrupting the possibility of air flow through the opening in the over-door space.
  • While closing the door (2), the door finger strikes the arm of the lever gearing (6), slews it and thereby opening the ventilation flap (5) by means of the second arm of the lever gearing (6).
    • Industrial Applicability
  • The technical solution is useful in manufacturing of fireplace inserts and fireplace stoves for solid fuel.
