Application August 28,

1 Claim.

This invention is applicable to refrigerators of any size but is more particularly valuable to that class of regriferators of the larger sizes in which meat and other perishable goods are kept and which are provided with refrigerating means to keep the meat and goods properly cooled.

An object of the invention is to prevent warm air pockets and to give the cold air currents the most effective direction.

An object is to provide air baffle pans having a forward gutter with an added pitch to speed up the water drain and being provided with a ledge to direct down draft and to prevent ice forming in the gutter.

Simplicity and moderate cost are also objects of the invention.

Another object is to provide baffles of siphon type which will assure perfect air circulation and keep the refrigerator free from sweat and moisture at all times.

Another object is to make provision for easily and conveniently cleaning the refrigerator throughout, so as to secure perfect sanitation.

It is understood that changes may be made in 5 the air circulation and construction of parts without departing from the scope of the invention or from the principles therein disclosed and claimed.

Other objects, advantages and features of invention may appear from the accompanying 0 drawings, the subjoined detailed description and the appended claim.

The accompanying drawings illustrate the invention.

1933, Serial No. 687,082

The refrigerator body is constructed with walls a, b, c, and 01, top 6 and floor f, enclosing a refrigerator chamber 1 and a storage and cooling room 2, and is provided in one end with the cooling and storage room door 3. 4 indicates a window in one end and 5 a window in the side. The door 3 is appropriately hinged as at 6 and secured with an appropriate latch as at 7.

The walls are preferably constructed with outside and inside wooden panels formed of tongued and grooved boards, preferably flooring nailed to upright studding, plates and sills forming chambers filled with insulation g.

The refrigerating chamber 1 is arranged above the cooling room 2 and is separated therefrom by the air bafiie pans 8 and 9 above which is provided refrigerating pipes 10 for the purpose of lowering the temperature of the cooling room.

The air baflie pans 8 and 9 comprise panels 11 and 12 that are fixed to the transverse members 13 and 14 and form the chambers filled with insulation 15.

16 indicates the wedge supports that are interposed between the panels 12 and support members 1'? that hold the air bafiie pans in position as shown in Figs. 1, 2 and 3 of the drawings.

The air bafi'le pans slope downward toward a central vertical plane which is indicated by the section line X2 in Fig. 1, and are provided with a galvanized iron or suitable covering 18 which overhangs as at 18a the forward gutters 19 that are provided with an added pitch beginning at 20 at the front end and sloping downward toward the rear end as at 21 as shown in Figs. 2 and 5 to speed up the water drain to prevent ice forming in the gutters.

The overhanging ledge 18a extends as far as possible over the gutter to still permit the water to drop into same. The heavy cold air hits the vair baffle pan and the pitch of said pan gives the cold air a momentum which with the aid of the ledge 18a, causes it to slide over without entering the gutter to any great extent; and then goes down through the cold air space 22 between the gutters 19 into the cooling room below as shown in Fig. l of the drawings.

To permit the water to escape from the gutters l9, outlets 23 are provided that empty into the drain gutter 24 that is fixed to one of the support members 17 at the rear end which is provided with a discharge outlet pipe 25 that empties into the drain pipe 26 that leads through the rear refrigerator Wall c into a sewer or other suitable drain, not shown.

Baiiles 27 of which there are two in number are shown mounted upon the highest edge of the air baiile pans 8 and 9 and extend from the front end to the rear end of the refrigerator and fixed thereto and held in alignment by the strips 28.

The said bafiles 27 comprise slats 29 that are arranged and spaced at an angle to form the openings 30 that permits the warm air to pass therethrough.

31 indicates the top strip and 32 the bottom strip and at 33 is shown a finishing strip which are all fixed to the baffle in a manner well known to the art.

The baflles 27 are spaced a certain distance away from the side walls d and g to form flues 33 that permits the warm air to rise from the cooling room 2 below.

I have thus provided means for collecting and discharging the drip water from the refrigerating chamber and have made provision for keeping the cooling room practically dry.

The air circulation is as follows: When the warm gases reach the ceiling of a refrigerator generally they will condense and leave the ceiling wet. The warm gases are drawn through the baffles 27 before they reach the top, are cooled by the refrigerating pipes 10 and become heavy and drop through the cold air space 22 into the cooling chamber 2 below.

As the cold air passes downward the warm air is drawn thru the baffles 27 to replace the cold air on its downward course.

Provisions stored within the cooling room 2 as well as thermal radiation from the refrigerator body cause a gradual rise in the cooling room temperature and the warmer air will gradually rise along the walls 01 and b of the refrigerator until said warmed air passes through the ilues 3S, and through the openings 30 of the baffles into the refrigerating chamber 1 as shown by the arrows in Fig. 1.

I claim:

In a refrigerator provided with insulated walls, top and bottom, and having a cooling room and a refrigerating chamber thereabove; insulated air baffle pans having a downward slope and separating said cooling room from the refrigerating room; means to support said air baffle pans; gutters fixed to the forward end of said air bafile pans and provided with an added pitch to speed up the water drain; a ledge extending partly over said gutters to direct down draft and to prevent ice forming in said gutters; said gutters being provided at one end with outlets that permits the water to drain through; a drain gutter directly underneath said outlets and means to drain water from said drain gutter to the outside of the refrigorator.
