Abstract
Abstract A method and apparatus for venting heated air from the upper portions of a room in a dwelling or the like, the invention acts to reduce heat loading within a building by providing a siphon vent pipe which opens into the upper portion of the room and extends upwardly into communication with a draft channel disposed near the roof of the building. Heated air within the upper portions of the room is thereby first vented from the room and then subsequently vented externally of the building through a vent formed in the roof of the building.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
234 words
In a building having a roof and at least one environmental space separated from the roof by at least a ceiling and an attic-like space between the roof and the ceiling, apparatus for causing heated air from the upper portions of the room to be vented from the building, comprising: a siphon duct member extending between the ceiling and upper portions of the attic-like space, the siphon duct member being opened at lower and upper ends, the lower end of the siphon duct member communicating with the upper portions of the room; means for defining a draft channel within the attic-like space, the upper end of the siphon duct member extending into the draft channel and communicating with the interior thereof to discharge air from the room into the draft channel; vent means for causing a flow of air through the draft channel from and to wherein the vent means comprise: a soffit vent formed in a lower portion of the roof and communicating the interior of the attic-like space with ambient, the soffit vent channeling a flow of ambient air into the attic-like space and subsequently into the draft channel; and, a ridge vent formed in an upper portion of the roof and communicating the interior of the draft channel with ambient, flow of air from the soffit vent passing through the draft channel and out of the building through the ridge vent.
Claim 2
Dependent Claim
234 words
In a building having a roof and at least one environmental space separated from the roof by at least a ceiling and an attic-like space between the roof and the ceiling, apparatus for causing heated air from the upper portions of the room to be vented from the building, comprising: a siphon duct member extending between the ceiling and upper portions of the attic-like space, the siphon duct member being opened at lower and upper ends, the lower end of the siphon duct member communicating with the upper portions of the room; means for defining a draft channel within the attic-like space, the upper end of the siphon duct member extending into the draft channel and communicating with the interior thereof to discharge air from the room into the draft channel; vent means for causing a flow of air through the draft channel from and to wherein the vent means comprise: a soffit vent formed in a lower portion of the roof and communicating the interior of the attic-like space with ambient, the soffit vent channeling a flow of ambient air into the attic-like space and subsequently into the draft channel; and, a ridge vent formed in an upper portion of the roof and communicating the interior of the draft channel with ambient, flow of air from the soffit vent passing through the draft channel and out of the building through the ridge vent.
Claim 3
Dependent Claim
51 words
In the structure of claim 1 and further comprising a nozzle member on the upper end of the siphon duct member, the nozzle member directing air flowing through the siphon duct member into the draft channel in a direction substantially coincidental with the direction of air flow within said draft channel.
Claim 4
Dependent Claim
31 words
In the structure of claim 1 wherein the upper end of the siphon duct member has the edges thereof aligned parallel with the direction of air flow within the draft channel.
Claim 5
Dependent Claim
33 words
In the structure of claim 1 and further comprising a fan disposed within the siphon duct member and adapted to evacuate air from the upper portions of the room into the draft channel.
Claim 6
Dependent Claim
40 words
In the structure of claim 1 wherein the means for defining the draft channel has an opening formed therein near the lowermost end of the draft channel, the opening communicating the draft channel with the interior of the attic-like space.
Claim 7
Dependent Claim
40 words
In the structure of claim 1 wherein the means for defining the draft channel has an opening formed therein near the uppermost end of the draft channel, the opening communicating the draft channel with the interior of the attic-like space.
Claim 8
Dependent Claim
27 words
In the structure of claim 1 and further comprising a layer of heat reflective material disposed at least on the upwardly facing surfaces defining the draft channel.
