FRIGIDAIRE CORPORATION, A CORPORATION OF DELAWARE REFRIGERATING APPARATUS Application filed November 80, 1925, Serial No. 72,096. Renewed December 18, 1928.

The present invention invention relates to refrigerators and particularly to refrigerators in which the cabinet thereof is divided into aplurality of compartments.

In certain types of mechanical refrigerator, water is frozen in receptacles and the ice blocks are removed from the receptacles and delivered to an ice storage chamber. One of the objects of the present invention is to simm plify this type of refrigerator. One manner of carrying out this object is to form a portion of a partition wall, which divides the refrigerator cabinet into afood compartment and a cooling compartment into a chamber for storing blocks of ice which have been frozen within the cooling chamber.

Another manner of carrying out the above object is to arrange the ice storage chamber in such a position with respect to the other portions of the partition wall that a plurality of air passages, connecting the compartments, can be arranged at different levels with respect to one another whereby natural circulation of air will take place.

Other and further objects of the present invention will be apparent from the following description reference being had to the accompanying drawings wherein a preferred form of embodiment of the present invention is clearly shown.

In the drawings:

Fig. 1 is a sectional view of the cabinet of the improved refrigerator showing a refrigerating machine in elevation.

Fig. 2 is a fragmentary sectional view taken on line 22 of Fig. 1.

Fig. 3 is a fragmentary sectional view taken on line 3-3 of Fig. 1, and

Fig. 4 is a front view in elevation showing a door of the cabinet open.

Referring to the drawing, the refrigerator includes a cabinet having a machine compartment 21, a cooling compartment 22 and a food compartment 23. The cooling com- .partment 22 and food compartment 23 are surrounded by insulation 25, the top portion 25 of the insulation being removable to provide access to the interior of the cooling compar tment 22. The cooling compartment 22 is provided with a lining 26 which forms the back, front and opposite side walls for said compartment. The lower portion of lining 26 extends inwardly to provide a flange 27. The compartment 23 is provided with a lining 29 which forms the bottom, back, front and opposite side walls for said compartment. The upper portion of lining 29 extends inwardly to substantially the same distance as the flange 27 of lining 26 to provide a flange 30. I

A partition wall 32 between

compartments

22 and 23 is secured to the

flanges

27 and 30 by bolts 33 which bolts are also utilized for securing flange 27 to flange 30, there being a gasket 34 interposed between these flanges. The partition wall 32 includes a downward. ly extending portion providing a chamber 36 which chamber includes a back wall 37. and a front wall 38, a bottom wall 39, a side wall 40 and an opposite side wall 41.

- The refrigerating machine herein shown is substantially the same as that shown and described in the patent to D. F. Keith, 1,510,147

of September 30. 1924, and shown in copending application Serial No. 3789, filed January 21, 1925. For the purpose of this invention it is deemed suflicient to state that this refrigerating machine is of the absorption type'including a generator-absorber 43 which i adapted to be intermittently heated 30 and intermittently cooled for intermittently forcing refrigerant therefrom into an evaporator 44 and for withdrawing refrigerant from the evaporator. As is disclosed in the aforementioned patent and application, the 35 entire refrigerating machine is pivotally mounted and the evaporator 44 is adapted to 'rock from the position shown in full line to the position shown in dotted line. The rocking from the full line position to the dotted line position is caused by the presence of substantially all of the refrigerant in the generator-absorber 43, and, the evaporator is rocked from the dotted line position to the full line position when substantially all of the refrigerant is in the evaporator 44.

Water receptacles 46 are provided in the cooling compartment 22 for receiving water which is delivered to the receptacles 46 in any suitable manner as disclosed in the previously mentioned patent and application. Ice pegs 47 attached to the evaporator 44 extend within the water receptacles 46. During the cooling phase of the evaporator 44, heat will be conducted from the water within the receptacles 46 to the evaporator 44 through the pegs 47, in order to freeze the water into ice blocks. After a predetermined period of the refrigerating cycle, the evaporator will move from the position shown in the full line to that shown in the dot and dash line and since the pegs 47 are located at an angle, the ice blocks 49 will be withdrawn from the receptacles 46. When the cooling compartment 22 becomes warmer the ice blocks 49 will slide from the pegs 47 and will fall into an ice tray 50 located within the storage chamber 36.

The front wall 38 of the storage chamber 36 is provided with an opening 51 through which the ice tray 50 may be removed. The ice tray has a handle 50 and a plate 50 which latter closes the opening 51 when the ice tray is in position in the storage chamber. The front wall 53 of the cabinet 20 is provided with a door opening 54 providing access to the food compartment 23. This door opening 54 is closed by door 55. The storage chamber 36 extends to such a distance within the food compartment 23 that the opening 51 of said chamber is in alignment with the door opening 54 whereby the ice trays 50 can be removed through said door opening. By constructing and arranging the elements as previously described, the ice trays are accessible and only one door is necessary to provide access to the food compartment and to the ice trays. Furthermore, the construction of the present refrigerator is relatively simple in that the partition wall between the cooling compartment and the food compartment is also utilized as a storage chamber for ice.

The inclined portion 41 of side wall 41 of chamber 36 is provided with an opening 56 and the artition wall 32 is provided with

openings

57 and 58 located at the front and rear of the cabinet and adjacent that side of the compartments op osite from the opening 56 and chamber 36. ince the chamber 36 is located below the other portion of the partition wall 32, the opening 56 is located at a lower level than the

openings

57 and 58. These openings being located at different levels, natural circulation of air will take place, the relatively cold air passing from compartment 22 into chamber 36 thence through opening 56 into the compartment 23, and the relatively warm air passing from the compartment 23 through openin s 57 and 58 and into the compartment 22. owever it will be noted that the opening 56 is above the bottom of the ice chamber and to one side of the ice drawer. Consequently the ice drawer is out of the path of air currents circulating thru the

openings

57 and 58 and 56. The ice therefore is in a pocket wherein the air is relatively quiet, this pocket being included between the portion of the inclined wall 41 which is below the opening 56,. the opposite side wall 40 and the front and

back walls

38 and 37 respectively. The cold air settling in the pocket of the ice chamber 36 will be further chilled and remain around the ice, and prevent the circulating air from causing more rapid melting thereof.

A drain 60 is connected with chamber 36 and extends through the lining 29 and insulation 25 and into the compartment 21. This compartment is provided with a'basin 61 for receiving water which water is conducted therefrom by a drain 62. All water of condensation which takes place within the compartment 22 will flow into the chamber 36 whence it flows to drain 60 into basin 61. Water from the melting ice within tray 50 will also flow from the chamber 36 through the drain 60.

It is apparent from the foregoing description that a relatively simple refrigerator has been provided. The partition wall between the cooling and food compartment provides means for readily draining water of condensation from the cooling compartment and also the melting ice. This partition wall also is formed in such a manner as to provide an ice storage chamber which may be maintained at a relatively low temperature so that the ice blocks are not readily melted, and the construction and arrangement is such that a plurality of air passages are provided between the compartments located at different levels whereby natural circulation of air may take place between the compartments.
