Abstract

Abstract A solar energy heat collector and storage chamber is provided with fixed side, rear, top, and bottom walls. A glass front wall permits sun rays to pass inwardly therethrough to heat rock pieces and also functions to help any heat from passing outwardly therethrough. This glass wall extends forwardly and downwardly. Behind and in spaced relation to this glass wall is a mesh screen wall which is preferably parallel thereto. Behind and in spaced relation to this screen wall are first and second baffle walls, the first forming with the screen wall a first rock chamber and the second forming with the first thereof, a second rock chamber. The first baffle wall extends from the top or bottom wall as a first wall, toward and short of the other wall thereof, while the second baffle wall extends from the other toward and short of the first wall. Such screen, first and second walls provide therebetween a circuitous passageway formed of first and second interconnected rock chambers, which are filled with irregular shaped pieces of rock, through which air may be circulated. The number of pairs of passageways and the length of the circuitous passageway may be increased and illustrative thereof, four are shown. The collector and storage chamber is connected with the hot air plenum chamber and cold air returns of a conventional hot air furnace. The furnace may utilize heat sources separate from the collector and storage chamber or the chamber may be the source of heat for the furnace.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 225 words
A heat collector and storage chamber having top and bottom walls forming vertically, spaced apart, horizontally extending walls, comprising a front, glass wall extending forwardly and downwardly in said chamber and disposed in the path of rays emanating from the sun; a front rock retaining mesh screen wall disposed in said chamber and in spaced relation to said glass wall; a first baffle wall disposed in said chamber, and in spaced relation to said screen wall and extending generally vertically from one of said horizontal walls toward but terminating short of the other wall thereof, thereby forming a first rock chamber with an adjacent one of said horizontal walls; a second baffle wall disposed in said chamber and in spaced relation to said first baffle wall and extending generally vertically from the other of said horizontal walls toward but terminating short of the one of said horizontal walls with an entrance adjacent the other of said horizontal walls, thereby forming a second rock chamber; a plurality of dark surfaces, irregular shaped pieces of rock disposed in said first and second rock chambers with spaces between pieces of rock; and air circulation means causing the air to pass in one direction in said first rock chamber, in the opposite direction in said second rock chamber, and to return to the entrance of the first rock chamber.
Claim 2
Dependent Claim 225 words
A heat collector and storage chamber having top and bottom walls forming vertically, spaced apart, horizontally extending walls, comprising a front, glass wall extending forwardly and downwardly in said chamber and disposed in the path of rays emanating from the sun; a front rock retaining mesh screen wall disposed in said chamber and in spaced relation to said glass wall; a first baffle wall disposed in said chamber, and in spaced relation to said screen wall and extending generally vertically from one of said horizontal walls toward but terminating short of the other wall thereof, thereby forming a first rock chamber with an adjacent one of said horizontal walls; a second baffle wall disposed in said chamber and in spaced relation to said first baffle wall and extending generally vertically from the other of said horizontal walls toward but terminating short of the one of said horizontal walls with an entrance adjacent the other of said horizontal walls, thereby forming a second rock chamber; a plurality of dark surfaces, irregular shaped pieces of rock disposed in said first and second rock chambers with spaces between pieces of rock; and air circulation means causing the air to pass in one direction in said first rock chamber, in the opposite direction in said second rock chamber, and to return to the entrance of the first rock chamber.
Claim 3
Dependent Claim 30 words
The combination of claim 1, wherein additional rock chambers are provided and air exiting from the second rock chamber is circulated therethrough and then returned to the first rock chamber.
Claim 4
Dependent Claim 35 words
The combination of claim 1, wherein an upper front, ray-masking door is hingedly connected with the top of the chamber and is movable into and out of ray-masking position relative to the front glass wall.
Claim 5
Dependent Claim 34 words
The combination of claim 1, wherein a lower front, ray-masking door is hingedly connected with the bottom of the chamber, is movable into and out of ray-masking position relative to the front glass wall.
Claim 6
Dependent Claim 21 words
The combination of claim 3, wherein the inner surface of said upper front door is provided with a sun ray-reflecting surface.
Claim 7
Dependent Claim 21 words
The combination of claim 4, wherein the inner surface of said lower front door is provided with a sun ray-reflecting surface.
Claim 8
Dependent Claim 55 words
The combination of claim 1 with a hot air heating furnace having a hot air plenum chamber and a cold air return wherein air leaving said second rock chamber is connected with said hot air plenum chamber through air ducts and said cold air return is connected with said first rock chamber through air duct.
Claim 9
Dependent Claim 23 words
The combination of claim 7, wherein air flow check valves are disposed in said air ducts limiting air travel therethrough to predetermined directions.
Claim 10
Dependent Claim 27 words
The combination of claim 7, wherein the air circulation means for said rock chambers is responsive to a selected temperature of the rocks in said rock chambers.
