Application August 26, 1952, Serial No. 306,368
2 Claims. (Cl. 237--16) This invention relates to improvements in hot air heating devices.
in applicants Patent No. 2,577,728 there is disclosed a thermosiphonic steam boiler in which water when heated in a lower horizontal chamber is lifted by a geyser tube to an upper horizontal chamber to facilitate the generation of steam.
It is an object of the instant invention to utilize the steam boiler in the aforesaid patent for circulating hot air.
A further object is to circulate water at a high temperature through a radiator by thermosiphonic means rather than using a pump.
Another object is to provide a hot air system in which it is never necessary to add moisture to the heated air.
An additional object is to decrease costs in the installation of heating systems.
Other objects of the instant invention will become apparent in the course of the following specification.
In the attainment of the aforesaid objectives, the boiler of Patent No. 2,577,728 has a closure with open top added to one end thereof. Horizontally positioned in the top of the closure is a radiator of known type and having an inlet port and an outlet port. The top of the geyser tube of Patent No. 2,577,728 is interconnected with the inlet port of the radiator while the outlet port of the radiator is interconnected with a water wall of the boiler at the bottom. In the bottom of the closure is a blower which draws air from the outside and forces it through a filter and thence through the radiator and out of the top of the closure for distribution. Special doors of light weight are provided for the open top of the closure and opened by the force of the air when the heater is in operation but which close under gravity when the heater is not in use.
The invention will appear more clearly from the following detailed description when taken in conjunction with the accompanying drawings showing by way of example the preferred embodiment of the inventive concept.
In the drawings:
Figure l is an elevational view of the improved hot air heating device in part section to more clearly show the internal construction; and
Figure 2 is a top view of the boiler shown in Figure 1.
Referring now in greater detail to the drawings where like reference numerals indicate like parts, reference numeral indicates the boiler illustrated and described in Patent No. 2,577,728, and 11 indicates the hot air heating device.
The boiler 10, as illustrated and described in Patent No. 2,577,728, is constituted in part of the water wall 12 interconnected with a lower horizontal water chamber 13. In spaced horizontal arrangement with the lower water chamber 13 is an upper chamber 14. Water is raised, when heated, from a well 15 in the lower chamber 13, interconnected with the water wall 12, by a geyser tube 1-6 to the upper chamber 14 to facilitate and hasten the generation of steam.
The hot air heating device 11 is constituted in part of a closure formed with the front member 17 in spaced parallel arrangement with a back member 18 and an end member 19 secured to the abutting edges of the front and back members in a known manner. The free edges of the front and back members 17 and 18 are secured along the corresponding edges 19 and 20, respectively, of the rectangular casing forming the shell of the boiler 10. In the end member 19 is an opening 21 for the intake of fresh air as later shown.
Over the open top of the closure formed as aforesaid are the doors 22 and 23 of light weight but rigid construction, being hingedly attached on opposite sides of the opening and designed to be opened by the heated air forced through the top of the opening as later shown. However, when no air is being circulated, the doors will fall under gravity to close the opening.
A radiator 24 of known type is secured in the top of the closure below the doors and is provided with an inlet port 25 and an outlet port 26. The upwardly directed end of the geyser tube 16 is interconnected with the inlet port 25 of the radiator. The outlet port 26 of the radiator is interconnected with the water wall 12, at the bottom, by the pipe 27.
A blower 28 of known type is inserted in the bottom of the closure to draw air from the outside through the opening 21 and force it upwardly through the radiator and the doors.
Intermediate the radiator 24 and the blower 28 is an air filter 29 of known type and secured in the closure in a known manner.
In operation:
When the water in the well 15 of the boiler 10 has been sufliciently elevated in temperature, it will be forced upwardly by thermosiphonic action through the geyser tube 16, the radiator 24, and the pipe 27 back to the wall 12 of lower chamber 13 for a repetition of the cycle.
While there is above disclosed but one embodiment of the hot air heating unit, it is possible to produce still other embodiments without departing from the inventive concept herein disclosed, and it is desired therefore that only such limitations be imposed on the appended claims as are stated therein, or required by the prior art.
What is claimed is:
l. A hot air heating device in combination with a thermo-siphonic boiler, the boiler having at least one horizontal chamber and a geyser tube disposed in said chamber and extending upwardly therefrom, the device comprising, in combination, a radiator, said radiator having an inlet and an outlet, means for interconnecting the upwardly extended end of the geyser tube to the inlet of the radiator, means for interconnecting the outlet of said radiator with said horizontal water chamber adjacent the bottom thereof, means for circulating air through the radiator, and means for filtering the air circulated through the radiator.
2. A hot air heating device in combination with a thermosiphonic boiler enclosed in a rectangular casing, the boiler having at least one horizontal water chamber and a geyser tube disposed in said chamber and extending upwardly therefrom; the hot air heating device comprising a closure with open top for one end of the rectangular casing, said closure comprising spaced parallel front and back members and an end member, means for securing said members along abutting edges, means for securing the free edges of said front and back members to the corresponding edges of the rectangular casing, one of said members having an opening formed therein adjacent the bottom, two substantially light and rigid doors for the open top of the closure, said doors being hingedly secured on opposite sides of said open top, at least one radiator horizontally disposed in the closure below said doors, said radiator having an inlet port and an outlet port, means for interconnecting the upwardly extended end of said geyser tube with the inlet port of said radiator, means for interconnecting the outlet port of said radiator with the interior of said water compartment at the bottom, a blower disposed in the closure below the radiator and coacting with the opening in one of the members of said closure, and an air filter disposed in the closure intermediate the radiator and the blower.
