REFRIGERATOR.

. Application mea 'April 22 My invention relates to improvements vin refrigerators particularly, though not eX- clusiVely,-for domestic purposes.

An object of the invention is to provide a simple and elicient refrigerator including simple and effective means for Ventilating the same. 1, ,f

A further Object is to supply such ve'ntilating means, the same being so associated with the refrigerating medium as to set up ventilation in the refrigerator by gravity.

Another object is to provide Ventilating means, as above, arranged to stimulate the circulation of air in the produce compartments, also to nrnimize humidity from accumulations of dondensations therein and, further, to utilize compartment ypartitions in the structure of said Ventilating means.

With the foregoing and other objects in lView, which will appear in the following description, the `invention resides in the novel combination and arrangement of parts Aand in the details. of construction hereinafter described and claimed. a

In the drawings, Fig 1 is a Vertical central sectional View of a refrigerator embodying my invention; Fig. 2 is a horizontal sectional view thereof,the same beingI taken on the line 2-2 ofy Fig.- 1 and Fig. 3

is a Vertical sectional View taken on the line 3-3 of Fig. 1.

Reference bein had to the drawing, it will be Observed t at my improved refrigerator includes the usual box-like cabinet A comprising a bottom 10, ends 11, front with doers 13 therein', v'back-14 and top 15, which cabinet is supplied with an inner lining 16 insulated, as at 17, from said parts of said cabinet. Within the cabinet is a hollow partition B, L-shaped in Vertical cross section, and consisting of anupright branch b and a horizontal branch 'b'. This partiton 'B provides a compartment C in an upper corner of a provision chamber D encased by the cabinet. The upper extremity of the upright branch b of the partition B falls short of the top Of the cabinet providing an elevated port 18, affording communication between the upper portion of the provision chamber D and the upper portici of the refrigerant compartment C. The eX- tremity' of the horizontal branch b of the partition B falls short of the adjacent end wall of the lining 16 providing a portk 19 affording communication between the lower portion of the refrigerant compartment C 1926. Serial No. 103,779.

and the bay in the provision chamber neath saidhorizontal branch b.

The upright branch b of the hollow partition B lconsists of two spaced walls 20 and 21, while the horizontal branch b of said partitions consists of spaced trays 22 and 23, the upper tray 22 branching olf from the wall 2.0 and the lower tray 23 from the wall 21. These Walls 20and 2l and trays 22 and 23 form between them an air passageway the cabinet from front to back. The space between the Walls 20and 21 at the 'upper edges thereof is spanned bya cap-piece 24: through which theflower end of an upright air ingress duct 25 opens. This duct eX- tends through the top 15 of the cabinet bringing the upper portion of the air passageway E in the partition B into communication with the outer air. way E is unobstructed at the extremity the horizontal branch of the partition B, said passageway, at this point, (opening into the duct 19 between the refrigerant compart- 90 nient (l and the provision chamber D.

Between thev walls 20 and 21 of the parl tition B is an upright egress duct 26 cpening at its upper end near the ceiling o the `provision chamber D, the lowerend of said as duct opening outwardy through the front 12 of the cabinet into the outer air. n A suitable air chilling medium, shown) such as ice or any of the conventlonal freezing units is placed within the refrigerant comartment C. In the presence of a chilling medium so disposed, an internal circulation of air is set up within the cabinet by gravity, such circulation being accompanied with Ventilation, also by gravity, through the ipgress of air to the cabinet and the egress of nair therefrom. The cycle' of the air in its internal circulation Within the cabinet may be traced beginning in the refrigerant compartment C, where the air, cooled by the refrigerant, descendsV byA gravity throughv the port 19- into the pro,-m

\vision chamber D. Heated in chamber' D' by the provisions and along the walls 'of .said chamber, the air rises `tO-the upper portion of the chamber and thence flows throu h the port 'p18 into the upper portion of t e refrigerant compartment C,lwhence the cycle 'is completed. In the present connection, it will be noted that the port 19, disposed .i along the end wall of the interior of the cabinet, providesior a thorough circulation E traversing the interiorl of Said air passageof air .in that portion of the provision chamber D beneath the refrigerant compartment C, no dead air being permitted to stand in said portion of said chamber. To comprehend the movement of the air in ventilating the cabinet, it must be understood that the wall 20 and tray 22 of the partition B are chilled by the refrigerant in the compartment C. The air in the passageway E, in turn being cooled by said wall 20 and tray 22, fiows out of said passageway into the port 19 throughv which the circulating stream of air is passing the air {iowing from said passageway E being replenished with fresh air entering through the duct 25. Coincident with such ingress of fresh air to the interior of the cabinet is the egress of air therefrom, the same taking place in the egress duct 26. This egress duct being cooled through the wall 20, under` the influence of the refrigerant in the compartment C, results in the cooling of the air in said duct 26. Said air thus affected flows by gravity out of the duct 26 to the outside of the cabinet, the same being followed by air entering the upper end of said duct. f The provision of the air passageway within the partition B is advantageous 1n that the incoming of fresh -air therein in a measure insulates the wall 20 and tray 22 from the wall 21 and tray 23 keeping the former wall and tray comparatively dry and thereby minimizing the percentage of humidity within the cabinet. Further, the wall 21 thus insulated from the wall 20 and affected by the incoming air is relatively warm, the result being that the upward movement of air in the provision chamber D along said wall 21 is stimulated as opposed to being retarded were said wall to be relatively cold.

`Condensation accumulating in the lower pan 23 is conducted from the cabinet through a main drain pipe 27. Likewise, condensation accumulating in the upper pan 22 is led away through astub pipe 28,which empl ties into said main drain pipe 27.
