The present invention relates to refrigerators, and particularly to refrigerators in which the mechanical apparatus and the compartment cooled thereby are contained- 5 within one cabinet.

In refrigerators of the above t pe it is desirable to cool the condenser of die refrigerating apparatus by air, and since refrigerators are often placed against the walls of a room, it is desirable to expel the air from the same side of the cabinet in which the door opening for the storage compartment is disposed. One of the objects of the present invention is to prevent the relatively l5 warm air which isexpelled from the machine compartment from entering the storage compartment when the door of said latter compartment is, open.

It is another object of the invention to di- 2 root the air leaving the condenser or machine compartment away from the air entering the machine compartment so that the relatively warm air will not be recirculated about the condenser.

I Further objects and advantages of the present invention will be apparent from the following description, to the accompanying drawing, wherein a preferred form of the present invention is 30 clearly shown.

In the drawing Fig. 1 is a front view of my improved refrigerator showing the door of the storage compartment open, and I F 1g. 2 is a top plan view ofthe refrigerator showing the machine compartment thereof in section, the section being taken on line 2-2 of Fig. 1.

Referring tothe drawing, indicates a refrigerator which is substantially the same as that shown in the copending application of Harry :8. Hull, Serial No. 147,862, filed Nov. 12, 1926. Cabinet 21 includes a storage compartment 22 and a machine compertinent 23 which are separated by a horizontal wall 24. The cabinetmay be rectangular in horizontal cross section, thus having four vertical outer walls, the front wall 26 of which is provided with a door 5 opening 27 and is closed by a door 28. This reference being had vers 32 direct 1927. Serial No. 202,619.

front wall is also provided with two sets of openings or

passages

29 and 30 which are formed by slitting vertically the sheet metal front wall and forming louvers 31' and 32.

The condenser 33 is disposed within the machine compartment 23 and comprises a plurality of turns of copper tubing vertically spaced from one another and for thepurpose of illustrating the resent invention, the condenser is herein s own as forming a part of a refrigerating. apparatus of the compressor-condenser-expander type in which a compressor 35 draws refrigerant from an evaporator 34, contained within the storage compartment 22, and forces the compressed refrigerant into the condenser 33. The compressor 35 is driven by an electrical motor 36 through a belt '37 connected with the motor pulley 38 and flywheel 39 of the compressor. A fan 40 is carried on the armature shaft of the motor and is disposed Within the turns of the condenser 33.

Rotation of this fan causes air to .be drawninwardly through the passages 29 and about the condenser 33 and expelled through the passages 30. A portion of the air entering the machine compartment will flow transversely across the coiland about the compressor and motor and transversely across the opposite end of the condenser and in the opposite direction while another portion of this air will flow longitudinally over the turns of the condenser The passages 29 preferably extend in a vertical direction and the louvers 32 are arranged to direct the air sideways away from the air inlet passages 29 and away from the door opening27. In this manner relatively warm air leaving the machine compartment will not enter the storagecompartment 22 when the door 28 is open while the refrigerating apparatus is operating. Likewise, the louthe air away from the passages 29 so that the relatively warm air will not recirculate within the machine compartment and the louvers 31 are arranged. so that relatively cool air will be taken into the passages 29 from a direction opposite the direction of the flow of expelled air.

While the form of embodiment of the ini tangular in vention as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.

What is claimed is as follows:

1. A refrigerator comprising a cabinet recs ta'ngular in cross section having a storage compartment, a machine compartment and four Vertical outer walls, one of said Walls of said cabinet having a door opening for the storage compartment and an opening in the machine compartment, an air cooled condenser within the machine compartment, means for circulating air outwardly from the anachine compartment through said latter opening, and means for directing said air sideways away from the door opening.

2. A refrigerator comprising a cabinet reccross section having a storage compartment, a machine compartment and four vertical outerwalls, one of said walls of said cabinet having a door opening for the storage compartment and a plurality of louvered openings for conducting air outwardly from the machine compartment, an air cooled condenser within the machine compartment, means for circulating air outwardly from the machine compartment through said louvered openings, the louvers being; arranged for di rooting air sideways away from the door opening.

3. A refrigerator comprising a cabinet rectangular in cross section having a storage compartment, a machine compartment and four vertical outer walls, one of said walls of said cabinet having a door opening for the storage compartment and a plurality of low vered openings for conducting air outwardly from and inwardly into the nachine compartment, an air cooled condenser within the machine compartment, means for circulating air outwardly from and inwardly into the machine compartment through said louvered openings, the louversv being arranged for directing air sideways away from the door opening, the louvered openings conducting the air outwardly being directed in a direction opposite from that of the louvered openings conducting the air inwardly.

In testimony whereof Ihereto afix my signature.
