UNITED STATES PATENT OFFICE.
MELVIN SOLOMON OROH, OF TORONTO, ONTARIO, CANADA, ASSIGNOR T0 JOSEPH MERCADANTE, OF NEW YORK, N. Y.
ELECTRIC HOUSEHOLD REFRIGERATOR.
Application filed December 31, 1924.
To all whom it may concern:
Be it known that I, MELVIN SoLoMoN GROH, a citizen of Canada, residing at T0- ronto, in the county of York,in the Province ofOntario, Canada, have invented a new and useful Improvement in Electric Household Refrigerators, of which the following is a speci cation.
My invention relates to an electric household refrigerator adapted to be more efiicient and quieter in operation than those heretofore in use.
I attain this object by the mechanism illustrated in the accompanying drawings, in which:
Fig. 1 is a vertical sectional side view of my device taken on the line 11 of Fig. 2; Fig. 2 is a vertical sectional front view of my device taken on the line-2-2 of Fig. 1.
Similar letters refer to similar parts throughout the several views.
A is an outside housing of wood, metal or any other appropriate material. B is a board of cork or other non-conducting material. C is an upper door opening into the A, D is a lower door opening into storage chamber A". E are lattices permitting the passage of air through condensing chamber A. L are wire meshes permitting the passage of air through condensing chamber A. F is the closed bottom housing of condensing cham-' her A with machine spring supports N, adapted to absorb vibration, and supporting the water tight base M, with surrounding water-tight rail M which sustains rotary pump Q enclosed in housing R with fins S, and also supporting condensing coil T and electric motor 0. Supports N are preferably three in number, so that by loosening two of them, and leaving fixed the one directly under tube V the entire base M and its contents can be swung out of the refrigerator for adjustment when necessary. W is a pipe leading from the outlet of pump Q to the intake end of condensing coil T. P is an air fan mounted on driving shaft Q which connects electric motor 0 with pump Q. V is the discharge pipe from the lower end of condensing coil T, and U is the intake pipe leading into the intake end of P p Q- ipes U and V pass. G is an outside floormg, with boards H of cork or other nonconducting material lying between, and sep- M is a manifold through which Serial No. 759,003.
arating chamber A from chamber A". is a protecting tube containing pipes U and V, and V is a drip drain pipe adapted to carry any drip water or moisture from floor .l down onto coil T and thencedown onto wa-' vent any drip moisture from running along floor J into cold air flue J. K is a vertical wall leaving open spaces at the top and bottom, so as to permit a circulation of warm air from the top of storage chamber A into the top of cooling chamber A, and to permit a circulation of cool air from the bottom of cooling chamber A through cold air line J into the bottom of storage chamber It will be understood that storage clnuuber A may be fitted with shelves, and-"with one or more doors as is usual. W is a diagrammatic view of a thermostat connected (by wires'not shown) with motor 0, and adapted to start motor 0 whenthe temperature of the air in storage chamber A rises above a certain point, and to stop motor 0 when the temperature of the air in storage chamber A falls below a certain point. X is a control valve adapted to control the flow of liquid refrigerant from pipe V into liquid refrigerant Z. Z are depending loop tubes, adapted to carry liquid refrigerant from container Z and to freeze water into ice in containers Z in housing Z Z are de pending loop tubes, adapted to carry liquid refrigerant from container Z. Z are fins homogeneously connected to said tubes Z and Z. freezing liquid contained in said fins Z will absorb the heat from the outside air as hereinafter explained, and will transmit said heat through tubes Z and Z, into the liquid refrigerant therein contained. It will be observed that fins Z almost completely fill the space of cooling chamber A, and that the The said brine or water or other tit) top line of said fins Z are substantially in largely increased, as the structure disclosed admits no air whatever to cooling chamber A except from the extreme top of storage chamber A, which necessarily means the air of the highest temperature therein. When said warmer air is thus drawn into the top of cooling chamber A, the heat absorption by fins Z and tubes Z and Z, very rapidly reduces the temperature of the air, and causes it to drop to the lower ortion of cooling chamber A" and thence t irough air line J into the lower portion of storage chamber A". Thereupon the cold air Wlll begin to absorb heat from, and thus lower the tem rature ol' the various foods and other things in storage chamber A", whereupon said air, with this additional heat, will rise to the top of storage chamber A, and the cycle of air will then begin anew.
The various elements of my complete device herein shown, including the refrigerat ing cooling means shown 1n chamber A, the air cooling device shown in chamber A. the machine spring support N shown in the bottom F of chamber A, the automat ic control valve X shown in chamber A, the manifold M shown in chamber A are oacll a separate and individual and divisional invention in my complete device as shown,
and each of the said elements is covered by a separate application for patent thereon.
I claim: 1. In an electric household refrigerator, a condensing coil located in a separate condensing chamber in the bottom of said refrigerator, a compressor adapted to convey a refrigerating medium under pressure into said condensing coil, a refrigerating cooling means located in 'aseparate cooling chamber inside the top of said refrigerator, and a drip drain pipe extending through the bottom floor of said cooling chamber and down through the top floor of said condensing chamber, the lower end of'said drip pipe being over the condensing coil.
2. In an electric household refrigerator, a cooling chamber containing refrigerating cooling means including a container, tubes each end of which open into said container, and fins the sides of which are attached to said tubes, said tubes and fins transversely filling practically the entire side and bottom space of said cooling. chamber.
3. In an electric household refrigerator,
a condenser adapted to condense a refrigerating medium therein contained, a compressor adapted to convey said refrigerating medium under pressure 1nto said condenser, a water-tight pan open at the top and supporting said condenser, the lower coils of thecondcnser being below the to of said pan, a cooling element in the re rigerator,
means for collecting the condense water from the cooling element, means forconveying said condensed water from the cooling element into the pan, and an air fan adapted to cool said condenser by means of air circulation and to evaporate the condensed water in said pan.
4. In an electric household refrigerator, a condensing coil, a pump and an air fan inside of said condensing coil, a member adapted to support said condensing coil, pmnp and air fan, and three machine spring supports sustaining said member, one of said machine spring supports being directly be-v neath the vertical alignment of the intake and discharge pipes of said pump.
