Air Blowing Arrangement For a Combined Refrigerator

Abstract

An air blowing arrangement for a combined refrigerator of the forced ventilation type and that comprises: a cabinet formed by an outer case and by two inner cases spaced from each other by a thermal insulating filler and defining a freezing compartment and a refrigerating compartment; and an air diffusing element defining at least one air distributing duct, having an air inlet in communication with the interior of the inner case of the freezing compartment and a plurality of air outlets opened to the interior of the refrigerating compartment. The air diffusing element is disposed in the interior of the thermal insulating filler and seated against the rear wall of the inner case of the refrigerating compartment, said rear wall being provided with a plurality of windows aligned with respective air inlet openings of the air distributing duct.

Description

FIELD OF THE INVENTION[0001]The present invention refers to an air blowing arrangement to be applied to a combined refrigerator of the forced ventilation type and presenting a single cabinet that internally defines a freezing compartment and a refrigerating compartment, usually separated by a horizontal dividing wall.PRIOR ART[0002]The combined refrigerators are generally constituted by a cabinet formed of an outer case, usually in metallic sheet, and by two inner cases molded in plastic material, EPS for example, which are spaced from each other and also from the outer case by a thermal insulating filler generally in polyurethane foam injected between said outer case and inner cases. The inner cases respectively define the freezing compartment and the refrigerating compartment, and the freezing compartment can be disposed above or below the refrigerating compartment and separated therefrom by the dividing wall.[0003]These combined refrigerators with forced ventilation are provided ...

AI Technical Summary

Benefits of technology

"The present invention provides an air blowing arrangement for a combined refrigerator that is simple and cost-effective to assemble. The arrangement includes an air diffusing body that is placed behind the rear wall of the inner case of the refrigerating compartment and is not visible to the user. The air diffusing body has multiple air outlets that are in communication with the interior of the refrigerating compartment. The arrangement can be used with different models of refrigerators and does not interfere with the esthetic design of the interior of the refrigerating compartment. The invention also provides an air inlet duct that can be used to keep the obturator away from the air cooling compartment when the latter is placed under the refrigerating compartment. Overall, the invention provides an efficient and aesthetically pleasing air blowing arrangement for combined refrigerators."

Problems solved by technology

This known construction requires the provision of a finishing cover to cover the whole extension of the diffusing duct, with the consequent costs in material and investments in moulds with considerably dimensions.

In addition to the inconvenience above, this prior art construction requires special cares for assembling the diffusing duct and its finishing cover, turning the assembling operations difficult and expensive and requiring a design for both the diffusing duct and the finishing cover for each model of combined refrigerator.

Finally, the fact of the diffusing duct-finishing cover assembly being exposed inside the refrigerating compartment restricts or impairs the introduction of new esthetic characteristics in the combined refrigerator.
