invention relates to refrigeration and more particularly to small household refrigerators of the type in which a refrigerating unit is removably assembled with a cabinet.
In accordance with this invention there is provided a simple household refrigerator which may either stand on the floor or hang on the wall and in which a refrigerating apparatus, with its heat emitting parts located in an air circulating flue, is readily removable as a unit from the cabinet, thereby affording ready interchangeability of units and cabinets.
Further advantages will be apparent from the following description taken in connection with the accompanying drawings, in which,
Fig. 1 is a vertical section of a refrigerator contemplated by this invention;
Fig. 2, a section taken on line 22 of Fig. l;
Fig. 3, a section taken on line 3-3 in Fig. 1; and
Fig. 4, an exploded view showing the removability of the several parts.
9' Referring to the drawings, the refrigerator shown in vertical section in Fig. 1 comprises two principal parts; a suitably insulated cabinet l0 enclosing a refrigerating compartment ll accessible through a door l2, and a refrigerating unit l3. These parts are shown separated in Fig. 4.
Referring to Figs. 1 and 2 of the drawings, the unit l3 comprises an open box-like framework closed at two sides by plates l4 and I5 leaving the top, bottom, and other two sides open. On this frame is mounted the refrigerating apparatus with the heat emitting parts l6 within the structure and the evaporator ll extending outwardly through one of the open sides. For purposes of illustration there is shown absorption refrigerating apparatus of the pressure equalized type having all the parts in open fluid communication and in which circulates an inert pressure equalizing medium such as hydrogen. For a detailed description and explanation of operation of this type of apparatus, reference may be had to Patent No. 1,609,334, Baltzar C. von Platen et al. and Patent No. 1,808,723 to Carl G. Munters.
The generator l8, absorber l9, condenser 2|, rectifier 22, and liquid heat exchanger 23 are all within the lower part of the framework and the gas heat exchanger 24 extends horizontally through an open side of the framework and conveniently supports the evaporator I! at its outer end. The side plates l4 and I5 may be provided with downwardly extending portions to form the rear legs 31 of the refrigerator or these legs may be made separately and demountably attached by bolts 25 as shown. The upper crossbar 28 at the rear of the apparatus framework may be provided with hook or eyelet portions 21 by which the refrigerator can be hung against a wall.
The refrigerator cabinet I0 is generally of any desired construction providing a heat insulated refrigerating compartment il accessible through a heat insulated door l2. In accordance with this invention a section of the bottom of the cabinet is omitted or out out, forming a channel or recess 28 extending forwardly from the rear edge of the cabinet and adapted to receive the connection from the evaporator to the. other portions of the refrigerating apparatus which is the portion of the gas heat exchanger 24 extending outwardly from the mounting frame of the unit. An aperture 29 from the recess 28 into the refrigerating compartment H is provided for the insertion of the evaporator I'I into the refrigerating compartment when the cabinet and unit are assembled, as hereafter described.
Referring more particularly to Figs. 1, 3, and 4, the apparatus unit l3 and cabinet II] are conveniently assembled by lowering the latter from a position shown in dotted lines in Fig. 4 down over the evaporator ll until the latter projects upwardly through the aperture 29 into the refrigerating compartment H and the gas heat exchanger 24 is positioned within the recess 28. The cabinet is secured in position to the mounting frame of the unit by any convenient means such as screws 30. The recess 28 is then .covered by a heat insulated wall section 3| and the aperture 29 is sealed by a gasket 32 placed between the evaporator I1 and a rim 33 around the aperture 29 which is conveniently formed by flanging up the liner of the cabinet around the aperture. After the cabinet and refrigerating unit are assembled, the cooling element herein referred to as a chilliator 34 is placed in the refrigerating compartment and secured to the evaporator II. The chilliator is preferably an aluminum casting formed with heat radiating fins 35 and recesses in whichtrays of water for freezing ice cubes or other substances to be frozen may be placed. The cast aluminum chilliator is bolted or otherwise secured in a good thermal contact with the evaporator.
The cabinet I0 is provided with two legs 36 which are preferably detachably mounted on the front corners, as shown, to form the front legs of the refrigerator. If the refrigerator is to stand on the floor, the rear legs 31 and front legs 36 are secured in position and the refrigerator placed against a wall to close the back of the re- Y is frigerating apparatus unit, thereby forming a flue II. In operation, cooling of the apparatus is aided by the upward draft of air induced through the flue 39 due to the heating of the air therein by the heat emitting parts of the ref-rigerating apparatus. If it is not convenient to stand the refrigerator against a wall, the open back portion should be closed by a sheet of suitable material, not shown.
This refrigerator may be made in small sizes which can conveniently be hung on a wall, as indicated in Fig. 4. In this case the front legs 30 are detached and also the rear legs 31, if desired,
and the refrigerator suspended by the eyelets 11 on hooks 38 or the like in the wall.
It will beobvious to those skilled in the art that various other changes may be made in the construction and arrangement without departing from the spirit of the invention and therefore the invention is notlimited to what is shown in the drawings and described in the specification but only as indicated in the following claims.
