My invention relatesto mechanically refrigerated food storage cabinets, and more particularly to cabinets in which mechanical refrigerating mechanism is mounted within !the casing. V
An object of myinvention is to provide a self contained mechanically refrigerated cabinet in which the mehanical refrigeratng apparatus can be readily associated or removed 10, as a unit. V
A further object of my invention is to provide a self cntained'mechanically refrigerated cabnet havingrelatively isolated refri" erated and machinery chambers with whch a unitaryrfrigerating apparatus is laterally movable relative thereto so that the evaporator will extend into the refrigerated chamber and the Operating mechanism will extend within the machinery chamber.
. Still another object of my invention is to provide a supporting frame, for mounting the evaporator and machinery of mechanical refrigerating apparatus in separate chamhers of a refrigerator which encloses the refrigerant conne'ctions between the evaporator and machinery interiorly of a refrigerator. Other objects of the invention, more or less incidental or ancillary to the foregoing will appear in the following description which sets forth in connection with the accompanying drawings a preferred embodiment of the invention; v
In the accompanying drawings Figure 1 is a front elevation of a mechani-- cally refrigerated refrigerator embodying my invention. v
Figure 2 is a section of the same, taken on line- 2- -2 of Fig. 1, and
Figure 3 is a section of the same, taken on line 3-3 of Fig. 1. t L
' Referring to the drawings by characters of reference, 11 represents a refrigerator having superposed isolated compartments 12 and 14, the upper refrigerated com artment 12 -receivi'g the cooling unit 13 o a mechanical refrgerating' apparatus and the com- `partment 14 being insulated from the refrigv erated ccpartment .to receive the machinery of the mechanical refrigerating apparatus.
The comp'artments have lateral openings on the same side of the refrigerator and are' separated by the partition 16, the front edge of whichis provided with recesses 17. Suitable movable closure members 10 are provided to close 'the lateral openings in the re- 'frigerator leading to the interior Compart- 18 which are Secured adjacent the upper ends 65 of the tubes 20. The base 19 has mounted thereupon the major portion of a compressorcondenser-evaporator refrigerating. apparatus, and directly supports all of the apparatus excepting the cooling unit,- expansion valve, refrigerant co'nduits and the thermostat control which are directly carried by tle tubes 20; A compressor 21, a driving u motor 30 and the transmission belt 3 1 exr tending therebetween are carried directly by the base 19. Likewise the con-denser 24: and a cooling fan (not shown) are also carried by the base. i r
The upright tubes 20 of the support are ^utilized to enclose the major portion of the refrigerant return conduit 23, which extends from thfiaporizer 32 to the compressor inlet 22, and the refrigerant feed conduit 28 which connects the xpansion valve mechanism 29 v with the condenser outlet( `A conduit 9 ex- 5 tends from the compressor outlet 26 to the condenser inlet 25 completing the refrigeri ant circuit.
The cooling unit 13 is carriedby the upper end of the upright tubes and the arms 18 which-extend therefrom, and consists of a brine tank 32 within which the evaporator' 'coils 8 are arrangedto sur-round a flue 35 for receiving an ice forming pan. The expansion valve 29 is carried by the cooling unit 'and connects the inlet end of the evaporator with the feed conduit 28. A thermostat 33 is also supported by the cooling unit, and is p suitably connected with 'conventional mech-` anism (not shown) for automatically con- 3 trolling the motor 30. A drain tray 36 projects from the standards 20 beneath the cooling unit to catch condensation, and is associated With the drain pipe 37 which leads the condensation exteriorly of the refrigerator in any conventional manner.
The refrigerating apparatus herein described is of the conventional automatically Operating compressor-condenser-evaporator type and a further description of the operation thereof to refrigerate the compartinent 12 is not deemed necessary to understand the invention. The refrigerating mechanism is carried entirely by the supporting frame and can be laterally moved through the openings leading to the compartments vhen" the closure members 10 are removed or opened. The upright tubes 20 can be moved into the recesses 17 in the partition 16 so that the supporting frame can be moved laterally p interiorly of the refrigerator and plugs 38 are associated With the tubes 20 to enclose the space in the recesses intermediate the tubes and the partition so that the compartments 12 and 14 will be isolated relatively;
It Will be seen that the evaporator is secured to thesupporting frame in a plane above the machinery portion of the refrigerating apparatus, so that it can be located in the refrigerated compartment while the machinery Will be located in 'the machinery compartment. It Will 'also be seen that the entire refrigerating apparatus is rem-ovab-le from the refrigerator, and that the refrigerant conduits are substantially enclosed by a portion of the supporting frame.
