This invention relates to refrigerators of the type employing water ice and is concerned with improvements in the construction thereof which ’ (@l. 62-81) . adapted to contain any suitable and well kno form of liquid secondary refrigerant. The wall 3 is preferably made in the form of 2. series of con make it possible to attainlower temperatures in , nected troughs to form a more or less corrugated 5‘ the storage spaces from ordinary water ice, to wall, thereby increasing the area thereof exposed ,5" ' create and maintain proper humidity in the stor age spaces, and to secure more uniform tempera. ture conditions therein. Generally, it may be statedvthat the mechanism 10 includes a heat exchange wall, in contact with which is. pieced the water ice-on one side and a erant, which is free to circulate therein under the suitable secondary liquid refrigerant circulating in thermosyphonic forces generated. heat exchange relation with the well and a heat from and connected to the wall 3 in heat ex collecting system exposed to the storage space 15 of the refrigerator. in'addition, there is em— ployed mechanism for insuring the presence of ‘the proper amount of moisture in the atmosphere of the storage space while arranging to collect end carry away any condensed moisture. -20 to the convection currents within the cabinet. The well 3 is sealed to the bottom of the shallow container 2 to produce a. series of disconnected and completely closed splices.v These spaces are ?lled with a liquid, so-called secondary, refrig- 1o These and many other objects as will appear from the following disclosure are secure by means of this invention. This invention resides substantially in the com bination, construction, arrangement and relative 25 location of parts, all as will be described in greater detail in the following speci?cation. ‘in the accompanying drawings, ‘ Figure; 1 is e. side elevational view of the mech enism comprising this invention within a heat do‘ insulated cabinet which is shown in cross-section; v Depending chsnge relation, by soldering, welding or other wise, are e series of ?ns t which likewise are it corrugated to increase the erea thereof. Secured to the lower edges of the outermost ?ns are a pair of brackets 5 and F5, between which extend and to which are secured a series of small troughs or gutters ‘i. The brackets are of dl?erent lengths 20 so that the gutters ‘i all have an inclination to wards the hack of the cabinet. Supported so as to be below the discharge ends of the gutters is a rectangular tank 3 which is mounted on the back wall of the refrigerator.’ This ‘container is pro- 25 vided with a discharge spout 9 in the bottom thereof which projects into a. waste pipe in ex tending to the exterior of the cabinet. Within the container 8 is a smaller container ll of rectangular form which is provided with a. dis- 30 “ Figure 2 is a. cross-sectional view taken on the ' charge or over?ow pipe H in the bottom wall line 2-2 of Figure 1; thereof which extends into the container and Figure 3 is a. top plan view of the inner moisture above the bottom waLlL'as is clear from Figures 1 end‘ 2. ‘Thespout I2 is positioned so that when 35 Figure d is a. top plan view ‘of the outer moisture the container ii is placed within the container 8 35 receptacle. it discharges into the spout 9. At i4 is a'dis As is well known, the ordinary water ice refrig- ' charge drain pipe for the shallow pen 2 which is orator is highly ine?icient and it is not possible positioned so as to discharge onto a. battle l3 to reduce the temperature in the storage space secured in the container Ill vso asfto divert the to thereof to anywhere near the temperature of the -,water discharged from the drain. pipe I4 from 40 water ice. In addition, refrigerators of this type direct entry into the spout i2. As is clear from‘ "Rare notoriously ineflicient in maintaining any the figures, the container ii is smaller than the receptacle; and _ , where near a uniform temperature within the‘ container 3 and sits therein spaced from all of its , storage space. The structure of this invention wells. ‘ makes it possible to attain much lower tempera. In the operation of the device, 9. block. of water 45 ~ turcs with water ice than’ is common practice ice is set in the shallow pan 2 so as to rest .on the today and to hold these lower temperatures uni bottom wall of the pan. The secondary refrig formly and at the same time insure ‘the proper erant is on the other side of this wall and carries humidity in the storage space. the heat absorbed from the storage space and £50 ‘One/form‘ of mechanism is illustrated in the . conducted to it by the ?ns 4 and the wall 3 to 50 drawings and comprises a. heat insulated cabinet the bottom wall of the pan where it gives this 6 of any suitable form and construction.

As the ice melts, the ice water the cabinet is mounted a shallow metal container is discharged through the drain ll into the con 2, which in conjunctionlwlth a. suitably formed tainer ii. The convection currents in the stor 55 bottom wall 3 formsra. closed circulatory space age space circulate upwardly when heated into 65 2 " ' ' 2,122,752 contact with the wall ,3 and the ?ns 4 and give up their heat thereto. Any moisture that collects on_the bottom wall 3 and the ?ns 4 drips into ~ the gutters ‘I and runs back into the container 5115.‘; By reason of the fact that the spout I2 is above the bottom of the container I! it will be apparent that a body of water will eollect therein 2.
