7 Claims.
The present invention relates to improvements in a refrigeration unit, and has particular reference to a unit of the character described in which storage space and an ice-maker are combined in the same cabinet.
In units of this character, means are usually provided for cooling the storage space by the circulation of air around the ice-maker, and through the storage space. In such an arrangement it bec mes necessary from time to time to de-frost the. ice-maker, and it has been customary to do this by shutting off the refrigeration apparatus and allowing the temperature in the ice-maker to slowly rise, which rise was accompanied by corresponding increase in the temperature prevailing in the storage compartment.
Such de-frosting required a considerable length of time, usually about six hours or more, and since the rise in temperature during such period was quite considerable, it would take a long time after the starting of the refrigeration apparatus to restore the storage compartment to a desired normal temperature.
In the present invention, I propose to provide means whereby the time period for de-frosting is reduced considerably and a quarterof an hour is usually suflicient to effect the desired results. This makes it possible to do the de-frosting' at any convenient time, and with a comparatively little raise in temperature in the storage compertinent More particularly, it is proposed to effect rapid de-frosting through suitable controlof air circulation. While normally, the air is circulated in such a manner that it passes around the icemaker and through the storage compartment, it is proposed in the present invention to provide a second path for the air, which causes the latter to travel right through the interior of the icemaker and thence through the storage compartment.
In this manner a much more rapid heat exchange is provided between the ice-maker and the storage compartment, and as a result, the temperature in the ice-maker rises rapidly, while the storage compartment substantially retains its temperature, the more rapid exchange make ing up, in part at least, for the loss'due to the stopping of the refrigeration apparatus.
It is further proposed to provide a very simple arrangement, whereby the air circulation may be shifted from one path to the other without any effort.
Further objects and advantages of my invention will appear as the specification proceeds and the novel features thereof will be fully set forth in the claims hereto appended.
The preferred form of my invention is illustrated in the accompanying drawing, in which:
Figure 1 shows avertical section through my refrigeration unit;
Figure 2, a vertical section taken along line 2-2 of Figure 1;
Figure 3, a vertical section taken along line 3-3 of Figure 2;
Figure 4, a vertical section taken along line 4-4 of Figure 1; and
Figure 5, a schematic front elevation of a unit, withthe wall shown in section. Y
While I have shown only the preferred form of my invention, I wish to have it understood that various changes or modifications may be made within the scope of the claims hereto attached, without departing from the spirit'of the invention.
Referring to the drawing in detail, my cabinet I may be of any suitable form, and comprises a bottom 2, a top 3, sides 4, a rear 5, and a front .6. The front preferably tapers into the top, as
shown at I, and may be formed with-suitable doors, as indicated at.8 and 9.
In its principal parts, the. cabinet is divided into three sections, a storage compartment I0 occupying the major portion of the cabinet, the
left side, as viewed in Figure 5; an ice-making compartment l l, occupying the upper portion of the right side of the cabinet, and a compartment l2 below the ice-making compartment for accommodating the compressor unit or refrigeration apparatus.
The ice-making compartment contains the icemaker l3, which may be of conventional construction, and which comprises, as here shown, a
box l4 having a plurality of shelves l5 arranged on the inside thereof and being providedwith cooling coils l8 underneath the shelves, the cooling coils being suitablyconnected. to the refrigerating apparatus accommodated in the com-- partment underneath, and ,not shown in the drawing.
The box I4 is provided with annular fins ll which run parallel to the front and rear walls of the cabinet. 1
The ice-maker occupies only the rear portion of the right-hand upper compartment, and, is
separated-from the storage compartment by -a vertical partition l8, and from the lower compart ment by a horizontal partition IS. The front of the ice-maker is generally open, as at 20, to allow of insertion of conventional trays, and is pro-- vided with a flange 2|, which fits against the walls of the compartment so as to separate the chamber 22 surrounding the ice-maker from the chamber 23 disposed in front thereof.
The rear wall 24 of the ice-maker is spaced from the rear wall of the cabinet, and is provided with apertures 25 which connect the inside of 7 the ice-maker with the air shaft behind the same. The vertical partition I8 is formed in its upper rear portion, and above the ice-maker, with an opening 26 in which is mounted a fan unit 21 comprising a housing 28, a fan 29, and a motor ment passes around the ice-maker, some along the near side and some along the far side, as indicated in Figure 2,and after being cooled by the ice-maker, returns to-the fan to be again discharged into the storage chamber for cooling: the latter and absorbing heat units therefrom.
. In the normal process of operation, the: air circulates continuously around the ice-maker and through the storage compartment, without coming into contact with the inside of the ice-maker.
For, de-frosting operations, I provide a second slot 32 in the lower portion of partition l8, the
second slot being in line with the slot 3| and being in: substance, a continuation of the latter into the front chamber 23. 1
A slide 33 is movably mounted with respect to the two slots 3| and 32, so as to coverone thereof. If the slide 33 is in the position indicated in Figure 1, the air circulation proceeds normally in the manner previously described, as indicated in Figure 2.
But if the slide 33 is moved backwards to close the slot 3|, and to open the slot, the air returning from the storage compartment, is cutoff from direct communication with the ice-making chamber 22 and instead, passes through slot 32 intothe front chamber 23.
From there its only approach to the fan is through the interior of the ice-maker and the opening in the rear wall thereof, as indicated in Figure 3; Thus-the relatively warm air coming from the storage compartment, passes in direct contact with the coils, and melts the ice formed thereon quite rapidly. j
If the trays are on the shelves, the ice therein will also melt away fromthe conventionalcells used in the trays, so that they may be more easily emptied. e v I In operation, the only adjustment required, is the pushing backward or forward of the slide 33. When the latter is in its forward position, circulation takes place through the slot 3| and around the ice-maker.
When the slide is in its rearward position, circulation takes place through the slot 32 and through the interior of the ice-maker ina fore and aft direction. a
I have found in actual experience, that the icemaker may be readilyde-frosted in a period of about fifteen minutes when the air circulation is changed to'pass through the ice-maker instead of around the same, while the. refrigerating apparatus is being stopped. I have also found that during this period, thefltemperature rise in the storage compartment is relatively negligible due to the'fact that the rapid de-frosting requires more heat units than would be absorbed in the conventional slow de-frosting. 1
