2 to 6 illustrate another mounting arrangement for the form of a composite refrigerator, in which the composite refrigerator is simply fitted inside the cabinet 10 at different locations selected along the height of the cabinet and the box 60 is supplied with refrigerated air. Refrigerating chamber RC formed by the interior volume of the cabinet except for the position occupied by freezer compartment FC formed by removable box 60 leveled into at least one outlet opening 52 of duct 50. It includes. Each box 60 provides an air inlet hole 62 provided in a wall portion adjacent to the refrigeration air supply duct 50, and is aligned with each outlet opening 52 of the refrigeration air supply duct, Allow refrigerated air flow into the box 60. Each outlet opening 52 aligned with the air inlet hole 62 of the box 60 of the freezer compartment FC has a respective valve 70 operated in the open state, while the box 60 of the freezer compartment FC is operated. The outlet opening 42 of the refrigerating air supply duct 40 facing the region of the refrigerating chamber RC occupied by has a respective valve 70 closed.

Each box 60 is provided with at least one air outlet hole 63 aligned with each inlet window 910 of each refrigeration air return duct 9 upon mounting of the box 60. The return duct has a plurality of inlet windows 91 open to the interior of the cabinet 10 to some other height, and the refrigerated air return duct 90 has an outlet window open to the interior of the air refrigeration chamber 15. 92 is provided upstream of each portion 20b of the evaporator 20.

The inlet window 91 of the refrigerated air return duct 90 is interrupted by a closure device 95, generally in the form of a plug, which plug is removed to release the passage of the refrigerated air flow through the inlet window 91. Possibly provided. To prevent refrigerated air from returning to the area of the evaporator through which the air refrigeration chamber 15 and the refrigerated air flow circulate, an inlet window 91 directed into the interior of the refrigerating chamber RC is provided by each enclosure 95. Is blocked.

In an embodiment, the provided refrigeration air return duct 90 is along the height of one of the side wall portions of the cabinet 10, between the inner and outer boxes 12, 13 and from the interior of the refrigerating chamber RF 15. Is formed through a part of the dividing wall portion 18 for separating and opening or closing the inside of each box 60 of the freezer compartment FC through each air outlet hole 63 of the box 60. It is directed into the interior of one side of the cabinet 10 through the inner box 11 to be closed by 95.

In an embodiment, the refrigeration appliance comprises a refrigerated air supply duct 40 and a refrigerated air supply duct 50 positioned vertically along the inner rear wall portion of the cabinet 10 and each outlet opening of both ducts ( 42, 52 are located in pairs adjacent to the sides, each pair is provided with a single valve 70 configured to close one opening of one pair and simultaneously open another opening of the same pair.

In a preferred embodiment, the valve 70 in the form of an angled double gate acts in opposing operating conditions on the cabinet 10 during the mounting and removal operation of each freezer compartment FC. It is constantly pressurized by a spring (not shown) means to an operating position that closes each outlet opening 52 of the refrigeration air supply duct 50 and opens each outlet opening 42 of the refrigerated air supply duct 40. It is preferable.

FIG. 7 illustrates an assembly in which the entire cabinet 10 is filled with a freezer compartment FC having the same dimensions, in which case the refrigeration appliance is responsive to the refrigerated air flow and acts only as a freezer with a fan 30.

The freezer compartment FC illustrated in FIGS. 2 to 7, 10 and 12 is in the form of a basic module having a height that does not tolerate the equipment of the inner shelf. 8, 9 and 11, however, the freezer compartment FC may be in the form of a double or triple module, in which case the box 60 corresponds to twice or three times that of the base module. Indicates height. In this case, higher height modules may be provided with shelves therein. On the other hand, the interior space of the cabinet 10 which is not occupied by the freezing chamber FC forms each refrigerating chamber RC provided with the shelf 19.

In order to mount the freezer compartment inside the cabinet 10, the cabinet 10 has a means for allowing the box 60 to slide like a drawer on the inner side wall in the form of a rail support or to be fitted at a selected position inside the cabinet ( Not illustrated) is provided. Similar systems are used to support the shelves 19 of the refrigerator compartment RC.

The box 60 of the freezer compartment FC maintains a gap with respect to the inner adjacent wall portion of the cabinet 10, but the box has a thermally insulated wall portion as a surround layer of cold air from the refrigerating chamber RC. Covered, making the interior of the box 60 more frozen.

The refrigeration appliance of the invention can operate as a compressor C of fixed or variable performance. In the case where a variable performance compressor is used, control of the refrigerating performance is performed by changing the rotation of each fan 30 or by changing the speed of the compressor C. As shown in FIG. If a fixed performance compressor is used, it is controlled only by the rotation of the fan.

Although described by way of example as some embodiments of practicing the invention, changes in form and relative position of other component parts may be made without departing from the spirit of the following claims.
