Abstract
ABSTRACT OF THE DISCLOSURE
A chimney flue with ventilator means, wherein at the upper part of a conventional chimney, a chamber is provided having an exhaust outlet above roof level and intended to contain one or more ducts for the ventilation of air and/or effluent gases, as from a sewer, the chimney and the chamber walls forming on the exterior a single, unified chimney top structure.
A chimney flue with ventilator means, wherein at the upper part of a conventional chimney, a chamber is provided having an exhaust outlet above roof level and intended to contain one or more ducts for the ventilation of air and/or effluent gases, as from a sewer, the chimney and the chamber walls forming on the exterior a single, unified chimney top structure.
Description
The invention relates to a chimney flue with ventilator means, Most houses today have both a chimney flue and one or more separate vent pipes covered by cowls for venting air from rooms where ven-tilation is desired, either by natural draught or mechanical ventilation.
It is previously known to provide chimney flues with an extra duct for ventilation purposes. Such extra ducts were often used earlier for ventilating laundry rooms.
When there is snow on the roof, the warm air vented through the ventilator cowls causes the snow around the cowl to melt. When the melted water runs off away Erom the cowl it may freeze to ice. Eventually, as the heated air passing through the ventilator cowl melts more and more snow, a mound or patch of ice may form which can damage parts of the roof gutters on the house, and/or water may collect in front of the ice mound and penetrate the roof, often at the location of the ventilator cowl. If water goes through the roof it will cause damage to the underlying wood, insulation and interior ceilings.
In addition to the problem of roof leaks and ice build-up associated with the use of ventilator cowls, such ventilator cowls are also costly to buy and expensive to install. They also require regular maintenance.
Another drawback of ventilator cowls is that their presence makes for a less esthetically pleasing roof surface. Furthermore, a hold must be made in the roof for a ventilation duct underneath each cowl.
The solution of providing an extra ventilation duct in connection with the chimney flue itself is little used. Such a ventilation duct runs the entire length of the chimney flue, making this solution very expensive and labor-intensive.
The object of the invention is to provide a chimney with ventilator means which is inexpensive to produce and which makes the use of traditional :^~
7~
ventilator cowls superfluous.
This objective is obtained in accordance with the invention by providing a chimney with ventilator means, characterized in that in connection wi-th the upper part of a conventional chimney flue, a chamber is provided having an exhaust outlet to the open air above roof level and intended to contain one or more clucts for ventilation of air or effluent gases, as from a sewer, said chamber having a lower end disposed a-t a relatively short distance below the lower surface ofthe roof.
In a further development of the invention, at the upper part of the chimney flue but below the location where the chimney passes through the roof into the open air, a support plate is fastened which on at least one side projects outwardly from the chimney flue and supports the abovementioned chamber.
I'he support plate may be bricked in or embedded within the chimney and may be formed with openings for the passage of ventilation and/or discharye pipes.
The empty space within the chamber may be filled with insulation material.
On the exterior, the chimney flue and the walls of the chamber above the support plate preferably form a single, unified chimneytop structure.
An embodiment of the invention is illustrated schematic-ally in the accompanying drawings, wherein:
Figure 1 shows a longitudinal section through the upper part of a chimney flue with the ventilator means of the inven-tion, and Figure 2 is a cross section along the line A-A in Figurel.

The drawings show a chimney flue 1 with an insulated 2 smoke flue 3. At the upper part of the chimney 1, below the location at which the chimney passes through the roof 4 to the open air, a support plate 5 is bricked in which on one side projects outwardly from the part of the chimney flue 1 below the plate and supports the walls of a chamber 6 containing ducts 7, 8 - 2a -~3~671~
for venting air or effluent gases, as from a sewer. The support plate 5 is formed with openings 9 for the passage of the ducts 7,8 and for the passage of the insulated smoke flue 3 of the chimney 1. The chamber 6 exhausts into the open air above the roof 4. On the exterior, the chimney flue 1 and the walls of the chamber 6 above the support plate 5 form a single, unified chimneytop structure, covered by a cowl 10 at the top. In the embodiment illustrated the ducts 7,8 pass into the chamber 6 through openings ~ in the support plate 5, but the ducts could alternatively enter the chamber 6 through the side walls of the chamber. The empty space in the chamber 6 is preferably filled with insulation material.
