Definitions
- the present invention refers to a combined refrigerator of the forced ventilation type with an air blowing arrangement, the refrigerator presenting a single cabinet that internally defines a freezing compartment and a refrigerating compartment, usually separated by a horizontal dividing wall.
- 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.
- These combined refrigerators with forced ventilation are provided with ducts for conducting cool air coming from the evaporator, to the freezing and refrigerating compartments.
- the cool air is produced in an air refrigerating compartment lodging an evaporator and a fan and which is disposed inside the freezing compartment, it is necessary to provide ducts that allow the cool air, which is produced upon passing through the evaporator, to be conducted not only to the freezing compartment inside which the air refrigerating compartment is situated, but also to the refrigerating compartment disposed below or above the freezing compartment, depending on the construction applied to the combined refrigerator.
- the conduction of cool air from the air cooling compartment to the refrigerating compartment is made through air passages provided in the horizontal dividing wall which separates the freezing compartment from the refrigerating compartment.
- the cool airflow After passing through said dividing wall, the cool airflow, to be released to the interior of the refrigerating compartment, is conducted through a diffusing duct mounted in the interior of the refrigerating compartment and seated and affixed against a rear wall of the latter, this diffusing duct being generally defined by an EPS body provided with at least one longitudinal slot opened to its rear face, against which is seated and affixed an adhesive blanket that operates as a sealing joint between the diffusing duct and the rear wall of the respective inner case.
- the diffusing duct body is provided with a plurality of air outlet openings turned to its front face and which are maintained in communication with the rear slot, in order to permit that the forced airflow admitted into the slot, by an adequately positioned inlet, be released through said openings in different levels of the refrigerating compartment.
- the diffusing duct is disposed inside the refrigerating compartment, therefore being exposed to the user upon the opening of the respective front door of the cabinet.
- this assembly it is necessary to provide a finishing cover to be affixed onto the diffusing duct, giving to the latter a esthetic aspect determined in the project of the refrigeration appliance.
- the finishing cover is designed to present openings or windows coinciding with the air outlet openings of the diffusing duct and also, optionally, an end portion with an increased depth, in order to define a chamber in which will be mounted an airflow control means for the diffusing duct, which can be defined by an obturator or a fan, depending on the design of the refrigerating appliance.
- 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.
- a refrigerator according to the preamble of claim 1 is known from EP-A-0 184 241 .
- a combined refrigerator as defined in claim 1 permits the air diffusing body to be disposed behind the rear wall of the inner case of the refrigerating compartment and, therefore, not visible to the user.
- the assembly of the diffusing body is effected concomitantly with the assembly of the outer case and inner cases, during the injection phase of the thermal insulating filler, dispensing esthetic finishings and leaving the interior of the refrigerating compartment free of covering pieces and liable to variations of its ornamental aspect.
- the air diffusing body can present two or more air distributing ducts and further at least one air inlet duct having an air inlet in communication with the interior of the inner case of the freezing compartment, and an air outlet in selective communication with the air inlet of the air distributing duct(s), said selective communication being controlled by the manual or automatic drive of an obturator or by the automatic drive of a fan, the automatic drive being achieved, both to the obturator and to the fan, through a driving means whose operation is controlled by a temperature sensor means mounted in the interior of the inner case of the refrigerating compartment.
- the provision of an air inlet duct along the air diffusing body is recommended to keep the obturator away from the air cooling compartment defined in the interior of the freezing compartment, when the latter is disposed under the refrigerating compartment.
- the present air blowing arrangement can be applied to the combined refrigerators of the no frost type and with forced ventilation, presenting the freezing compartment FC disposed above or under the refrigerating compartment RC.
