ll/ly invention relates to improvements in food cabinets the objects of which to pro- `vide means whereby the cabinet may be divided into separate compartments, one of which is insulated against the'ingrcss of heat and'is capable of use as a retrigerator using ice as a cooling medium, or to be equipped with an evaporator.' unit of a mechanical refrigerator system. Also to provide` means whereby a circulation of air may pass from one compartment to another around the one insulated that they may be eflectively venti.- dated during periods of high temperature when the insulated compartment is in use as a refrigerator, and to provide means whereby a circulation of air may pass through all the compartments during periods of low temperature, or whenno extraneous cooling medium is used in the insulated compartment.
The invention consists essentially of a ventilated cabinet having an insulated compara ment disposed intermediate its height and spaced apart from seine of the side walls of the cabinet, said insulated compartment being provided with closable openings in its opposite side walls, so that the air flowing through the cabinet may also flow through the insulated compartment, as will be more fully described in the following specification, in which Fig. 1 is a sectional view of the invention taken on the line 11 of Figure 3.
Fig. 2 is a front view.,
Fig. 3 is a sectional view taken on the line 5%#3 of Figure l.
Fig. 4l is a sectional view taken on the ,line tl of Figure 1.
ln the drawings like characters of refer ence indicate corresponding parts in each ligure.
The front wall (i is provided with a pair of doors 8 adjacent the top and bottom thereof, which are suitably fitted with hinges 9 and catches 1.0, and intermediate the vertical length of the wall is a suitablv insulated door 11 preferably litted with. retrigerator hinges 12 and fastener 13. Fitted to the rear of the front wall G is a refrigerator compartment 1d which is slightly less in cross sectional area than the cabinet 1 to provide a plurality of spaces or air ducts 15. rlhis compartment divides the cabinet to define a lower compartment 16 and an upper compartment 1'? both of which may be titted with shelves 18 if desiredu rlhe refrigerator compartment 1t is provided with insulated side and rear walls 19 ano top and bottom walls L0 having apertures 21., 'iheseapertures are adapted to be closed by removable plugs 22 which are made of sheet corlr or other non-conducting material and are preferably held in place by friction, though any other holding means may be adopted.
Having thus described the several parts of my invention l will now briefly explain its function.
VFhe cabinet is assumed to be fitted with its Ventilating grilles Y in communication with air ducts extending through an outside wall of the building. During the warm weather when refrigeration is desirable and the quantity of perishable foodstuffs carried in the home is relatively small, the plugs 22 are set into the apertures 21 of the insulated compartment 1a, a cooling medium used and the foodstuffs stored therein. Foodstutls of a semi-perishable nature, such as bread or other things which will keep at normal temperatures, being stored in the lower or upper compartments 16 and 17 where they are subjected to ventilation consisting of a flow of air entering through one of the Ventilating grilles l and its compartment, thence through the ducts 15 between the insulated compartment and the walls of the cabinet, through the other con'ipartment and finally outwards through its ventilating grille. ln the cooler weather, the use of ice or other cooling medilill) llt) um in the insulated compartment may be dis pensed With and the entire cabinet used as a unit under an equal temperature throughout its several compartments by removing the plugs 22 and allowing a llow of air to pass therethrough.
It Will thus be seen that I have invented a food cabinet having upper .and vlower food compartments and an insulated intermediate compartment capable of being used las a rerigerato-r when required, and when so used an adequate y'fresh air ventilation is provided tofthe other compartments, also, that during such times as refrigeration is not required 'that 'fresh ai-r venti-lation is continuously provided through all the Acompartments.
lVhat I claim as my invention is:
A food cabi-net comprising -a casing having top and bottom openings for the circulation of air therethrough and provided ivi-th upper, lower and intermediate doors giving access to corresponding interior port-ions of 4the casing, the upper and lower portions of `the casing being provided with shelves designed'to support food or other Yart'icles'therein Without obstructing the `passage of air through .the casing, an'insulated compartment Vmit air to pass through as occupying the intermediate portion of the easing and secured to that wall portion of the easing by which the said intermediate door is carried and being accessible through said door, said insulated compartment heilig spaced from the remaining surrounding Wall portions ot the casing to provide air flow passages connecting the upper and -lower portions of the casing between which the insu- Clated compartment is situated, refrigerant and article supporting means contained within said insulated compartment, there inning openings formed in thc top and bottom Wall portions ot the insulated compartment `to perwell as around `said compartment when outside temperature conditions are such that circulation of outside. air through vthe easing and compartment is sutiicient to preserve the articles contained ltherein and `means for closing the openings in said compartment when temperature conditions vare such as to require lthe use of a refrigerant therein.
