9 Claims.
My invention relates to refrigerating apparatus and particularly to mechanical refrigerators having a plurality of heat absorbing elements.
It is an object of my invention to provide a mechanical refrigerator embodying means to absorb heat from the air in the lfood storage compartment and means to congeal Vliquids in a separate compartment without materially affecting the temperature of the air in the food storage y 10 compartment. f
"It is another object of my invention to provide a mechanical refrigerator in which the ice freezing compartment, the heat absorbing means and the air circulatingmeans may be removed fr om 1 5 or inserted into the food storage compartment as a unit. I
It is a further object of my invention to provide a mechanical refrigerator in vwhich the refrigerant circulating means and the heat absorbing means are removable from or replaceable in the cabinet as a unit without breaking the refrigerant connections therebetween. A
'I'hese and other objects are.1 effected byY my invention as will be apparent from the following description and claims, taken in connection with the accompanying drawing, forming a part of this application, in which:
The single figure is a diagrammatic sectional View of a refrigerator embodying my invention.
Referring tothe drawing for a detailed descrip-v tionof my invention, numeral I0 designates, generally, a refrigerator cabinet embodying a food storage compartment II and an apparatus compartment I2. The food storage compartment' |I is provided with an access opening I3 which is sealed by a closure member I4. A'second opening I6, which is closed by a removable heatinsulated wall portion I'I, is provided in the food storage compartment |I in the wall opposite the access opening I3. l 3
A refrigerating system associated with the refrigerator cabinet includes a first heat absorbing element 2| for absorbing heat from the ambient air in the food storage compartment II and av .4'5 second heat absorbing element 22 for absorbing heat from a heat insulated ice freezing compartment |8 disposed in the lower portion of the food storage compartment The heat absorbing elements 2| and 22 are of the evaporative type. A compressor 23 withdraws refrigerant vapor from the heat absorbingelements 2| and 22 'and circulates it to a condenser 26, cooled by a fan v2'I, wherein it is condensed. An expansion device shown diagrammatically at- 28 distributes the condensed refrigerant to the heat absorbing `ele- (Cl. (i2-416) ments 2| and 22. The compressor 23, its 'driving motor 24,' the condenser 26,-the condenser fan 21 3 vand the expansion device 28 are assembled on a base 29 disposed in the apparatus compartment I2. The base 29.with the apparatus assembledl 5 thereon is removable from or insertable in the apparatus compartment |2as a unit thereby facilitating the service and repair of the apparatus. The ice freezing compartment I8 is formed of a 'rectangular outer metal shell 3| anda similarly 10 shaped smaller inner metal shell 33. The inner metal shell 33 is telescoped within the outer metal shell 3| and is positioned therein so as to provide a spacev between the two shells. A heat insulating material 38 is provided in the space between 15 the shells 3| and 33 in order to. reduce the'heat transfer therebetween. A flared portion 31 of the inner shell 33 engages the wall of the outer shell* 3| near its open end and is secured thereto, preferably by welding, in order to .provide a moisture- 20- proof joint between the shells. The second heat absorbing element 22, which is formed of a continous copper tube of substantial length, is provided with an inlet 38 and an outletl 39 and is shaped to conform'to the inner'periphery of the 25 inner shell 33 to provide a freezing chamber 4| ,within the ice freezing compartment IIl.A The heat absorbing element 22 is held in intimate contact'with the inner shell 33 by a rectangular shell 42. A tray 41 containing liquids to be con- 30 gealed is disposed in intimate thermal contact with the shell 42 and the heat absorbing elemnt- 22. A door 4.8 is movably secured to the outer shell 3| 'and provides aclosure for the open end of the ice freezing compartment I8 so that it is 35 'accessible through the access opening'I3. The
construction of the ice freezing compartment I8 makes it possible to congeal liquids in the tray 4'I at arapid rate without materially affecting the temperature of the ambient air 'in the food 40 storage compartment The rst heat absorbing element 2| is positionedin' the food storage compartment I| be.'- tween the ice freezing compartment I3 and the wall portion il. The heat absorbing element 2| 45 comprises a metal cage member 49 formed. of a pluralityof 4radially extending fins 5`I with a cylindrical opening 52'.through the center. vA continuous copper tube '5.3, having `an'inlet 54 y which is connected to thev outlet-39 of the second 50 heat absorbing element 22 and an outletal55, passes through the ilns II, as shown In the drawing. A fan 51 is disposed within the cylindrical opening 52 in alignment withthe heat absorbing elements :AI anni, 'and wan the freezing chamlili ber I8. 'I'he fan I1 is driven by a motor I8 which is supported .by the wall 'portion I1 outside the food storage compartment II. 'I'he fan 51 forces the air in the food storage compartmentv II over the heat absorbing element 2l and then toward the upper portion of the food storage compart- A temperature responsive device 58 is disposed Y within the food storage compartment II and is used to control the operation of the motor 58' in vresponse to the temperature of the air in the food storage compartment II. Corresponding electrical connections 65 and 88 on the temperature responsive device 59 and on the fan motor 58 are connected together (not shown). 'I'he operation of the motor 58 is independent of that of the motor 28 and is effected when the temperature of the air in the food storage compartment II reaches a predetermined upper limit. Operation of the motor 58 will be discontinued when the temperature of the air has reached a predetermined lower limit corresponding to the cutout setting of the temperature of the temperature responsive device 59.
In accordance with my invention, the heat absorbing elements 2| and 22, the heat insulated ice freezing compartment I8 and the fan 51 are disposed in the food storage compartment II in alignment with the second opening I 8. 'I'he heat' absorbing element 2| and the ice freezing compartment -I8 with the heat absorbing element 22 as a part thereof are supported by a bracket I9 which is rigidly secured to the wall portion I1. Thus the ice freezing compartment I8 with the heat absorbing element 212 associated therewith, the heat absorbing element 2|, the fan 51 and the fan motor 58 assembled as a unit with the wall 'portion I1 may be easily removed from. or in- 'I'he compressed vapor refrigerant is condensed in the condenser 26 and is distributed by the expansion device 28 to the heat absorbing element 2l and 22 through a conduit 82 which connects the expansion device 28 with the inlet 88 of the. heat absorbing element 22. The compressed refrigerant vapor is conveyed from the compressor 23 to the condenser 28 through a conduit 88. A`
conduit 68 conveys the liquid refrigarnt from thecondenser 28 tothe expansion device 28. The liquid refrigerant entering the heat absorbing element 22 absorbs heat from the ice freezing compartment I 8, and congeals the liquid in the tray 41 without materially affecting the temperature of the ambient ir` in the food storage compartment II. From the heat absorbing element 22 a-nilixture of liquid refrigerant and refrigerant. vapor passes in series to the heat absorbing element 2| to absorb heat from the air which is driven over the heat absorbing element 2I by the action of the fan 51 when refrigeration is |required in the food storage compartment Il. The
vaporized refrigerant then returns to the compressor 23 .through the conduit 8| completing the cycle. When the temperature of the food storage compartment II has'reached the lower limit for which the temperature responsive device 59 a,1os,4ao
fan'u wm no longer arcuate air in un roodstorage compartment II over the heat absorbing f element 2I and the'cooling fins 8l with the result that the refrigerant passing through the heat absorbing element 2| will have little or no effect on the temperature of the food storage compartment I I..- L
The conduits 8Iand 82, both of which passA out of the apparatus compartment I2 and upwardly along the outside of the refrigerator cab' iiet III into the food storage compartment II through Vthe wall portion I1 toconnect with the outlet 85 of the heat absorbing element 2l -and theinlet 88 of the heat absorbing .element 22re spectively, are preferably flexible and afford the removal from or replacement in the refrigerator cabinet ofthe plug I1 together with the elements associated therewith without breaking any of the physical connections between the respective elements or between the elements supported by the wall portion I1 and those elements disposed in the apparatus compartment. It is also possible to remove the base 28 with the apparatus assembled thereon from the apparatus compartment I2 at the same time thatthe wall portion I1 and its associated apparatus is removed fecting the temperature of the air in the food storage compartment. It is also apparent that the apparatus disposed in the apparatus comparti ment and that disposed in the food storage compartment may be removed from or replaced in the respective compartments without breaking any of the physical connections necessary for the operation of the apparatus.
