Claims.
My invention relates to heat operated refrigeration systems and particularly to the generator assembly of such systems.
An object of my invention is to provide an improved construction and arrangement of elements in the generator assembly of a heat operated refrigerating system.
The invention together with its objects and advantages will be more clearly understood from the following description and accompanying drawing, wherein:
Fig. l is a top plan view, partly in section, of a generator assembly incorporating my invention.
Fig. 2 is a top plan view of a part of the assembly showing a preferred form of my invention.
A generator ID, of the horizontal type, is provided with a longitudinally extending inner flue it running therethrough. A fluid fuel burner (not shown) is mounted adjacent the inlet end ii of the flue ll so as to direct its flame into the flue. The outlet end l3 of the flue communicates with a horizontal portion of a chimney it which is provided for the disposal of products of combustion. Closely fitted within the flue, adjacent its outlet end 13, is a flue baflie l5 which acts to inhibit the flow of the products of combustion whereby the heat exchange is made more thorough. A retainer wire it having an offset portion I? and a threaded end i8 is pivotally connected at one of its ends it to an end of the flue baflie [5. A cleanout cap 20 is provided to close off the cleanout end 2| of the chimney l4 during operation of the apparatus. The working media inlet and outlet connections to the generator, not being a part of this invention, have been omitted from the drawing.
When the apparatus is mounted within a refrigerator cabinet (not shown) the generator is positioned in a lower part of the cabinet so as to be in a horizontal plane within the lower front of the cabinet causing the chimney to lie parallel to a side wall of the cabinet in a horizontal plane with its cleanout end 2| directed towards the front of the cabinet. With the apparatus mounted in this manner the chimney and the flue may be cleaned from the front of the cabinet.
In assembling the flue bafile, retainer wire and cleanout cap in their respective places, the end it of the retainer wire is inserted through a hole in one end of the flue baflie and then bent back upon itself so as to form a linked connection between the retainer wire and the flue baflle. Any other type of movable joint would be suitable. The retainer wire-flue bafiie assembly i then inserted, retainer wire first, into the inlet end [2 of the flue. For reasons to be later explained, care must be taken to be sure that the ofiset portion ll of the retainer wire is directed towards the rear of the cabinet when the retain-er wireflue bafiie assembly is inserted into the flue. The retainer wire-flue baffle assembly is then pushed into the flue to the outlet end thereof. When the threaded end I8 of the retainer wire abuts against the inner surface of the chimney, the retainer wire will pivot about its point of junction with the flue bafile and turn into the front end of the chimney. The oflset portion ll of the retainer wire acts as a bumper against a rear portion 22 of the generator flue chimney junction and nestles down over a front portion 23 of the generator flue chimney junction thus forcing the retainer wire to turn into the front end of the chimney.
The cleanout cap 20, provided with a hole to receive the threaded end [8 of the retainer wire which projects out of the front end of the chimney, is now slipped onto the threaded end of the retainer wire and a wing nut 24 is screwed onto the threaded end of the retainer wire forcing the cleanout cap against the end of the chimney so that the cleanout opening 2| is completely covered. In this manner, as shown in Fig. 1, both the flue bafile and cleanout cap are secured in their respective positions by the threaded engagement of the nut 24 to the retainer wire. The burner (not shown) is now mounted in place at the inlet end of the generator flue and the apparatus is ready for operation.
When it is desired to clean the generator flue and chimney, the burner, cleanout cap and flue baffle retainer wire assembly are removed. The burner is first removed, then nut 24 is removed from the retainer wire, whereby the cleanout cap 20 will drop 01f the front end of the chimney and the flue baffle-retainer wire assembly may easily be pulled out the inlet end I2 of the generator flue. The retainer wire will negotiate the flue chimney junction in the same manner as previously explained. The chimney and generator flue may then be cleaned from the front of the cabinet. In reassembling the apparatus it is necessary that the flue baflie be replaced in its proper position, otherwise the cleanout cap for the chimney cannot be attached to the retainer wire. In this manner it is assured that the flue bafiie is properly positioned within the generator flue.
While I have shown only one embodiment of my invention, I realize that many modifications may be made by anyone skilled in the art and I therefore desire to be limited only by the extent of the following claims.
What is claimed is:
1. A generator assembly for supplying heat to a heat operated refrigeration system comprising a. flue, a chimney connected to the flue, a flue baffle within the flue, a cleanout cap for closing off one end of the chimney, and a retainer wire attached at one of its ends to the flue baifie and at the other of its ends to the cleanout cap se curely holding the flue bafile and the cleanout cap in their respective positions. I
2. Heat transfer apparatus as described in claim 1 wherein the retainer wire has an offset portion intermediate its ends.
3. A generator assembly for supplying heat to a heat operated refrigeration system comprising a flue, a chimney at one end of the flue and having an open end, a cleanout cap for closing the open end of said chimney, and a flue bafile within the flue having means attached to one end thereof adapted to removably secure the cleanout cap over the open end of the chimney.
4. A generator assembly for supplying heat to a heat operated refrigeration system comprising a generator, a flue passing therethroug'h, means in said flue for inhibiting the flow of products of combustion therethrough, a chimney adjacent one end of said flue, said chimney being provided with an open end, means for closing the open end of said chimney, and a single connecting means for removably securing both of the aforementioned flow inhibiting and chimney closing means in their respective positions in the assembly.
5. A generator assembly for a heat operated refrigeration system comprising a flue, a chimney having an angular junction with said flue and an opening adjacent the juncture but out of line with the flue, a removable baffle in the flue, and a retainer link pivotally connected at one end to said baffle and having an offset portion for directing the link around the corner at said juncture and toward the opening in the chimney, and means c0-operating with the other end of the link at said opening to hold the bafile in operative position in the flue.
