Description

Structure of refrigerator

Technical Field

The present invention relates to a refrigerator structure having a dedicated device dedicated to handling the accumulation of water from external moisture condensation that can occur depending on the number of times the refrigerator door is opened.

Background

As is well known to those skilled in the art, a refrigerator is a household appliance for climatizing at least one refrigerating compartment in which products (generally food) can be stored and preserved.

According to the current state of the art, there are models of refrigerators in which the refrigerating chamber is cooled by a flow of cold air coming from a cooling unit (compressor, evaporator and ventilation device), circulating inside said refrigerating chamber.

In particular, it is observed that there are models of refrigerators in which the cold air outlet from the cooling unit is arranged on the rear wall of the refrigerating compartment.

In addition, it should also be noted that some refrigerator models are provided with a plurality of cool air outlets disposed on a rear wall of the refrigerating compartment, and thus, a vertical duct capable of supplying cool air from the cooling unit to the plurality of cool air outlets is provided.

The functional principle of refrigerators based on refrigerant fluid compressors is well known to the person skilled in the art.

Among these functional principles, it should be noted that the constant opening of the refrigerating compartment door eventually generates condensation droplets, which are the result of the combination of the humidity outside the cooling compartment and the internal temperature of the refrigerating compartment. Due to the effect of gravity, these condensation droplets tend to accumulate in the lower portion of the refrigeration compartment, often forming puddles which can contact the food products placed in the lower portion of the refrigeration compartment, thereby destroying the integrity of the food products and shortening the useful life of the food products.

Based on this situation, the utility model discloses appeared.

Purpose of the utility model

Therefore, the main object of the discussed utility model is to disclose a new refrigerator structure which is capable of preventing condensation droplets from accumulating on the lower part of the refrigerating compartment.

SUMMERY OF THE UTILITY MODEL

The above objects are fully achieved by a refrigerator structure comprising at least one refrigerating compartment and at least one cooling unit integrating at least one refrigerant fluid compressor, at least one evaporator, at least one condenser, at least one fluid refrigerant expansion device and at least one cold air ventilation device. Also, at least one fluid communication aperture disposed between the refrigeration compartment and the cooling unit is provided, wherein cool air generated in the cooling unit reaches the refrigeration compartment through the fluid communication aperture. At least one horizontal rib disposed on at least one wall of the refrigeration compartment is also provided. Preferably, but not limitatively, the horizontal rib comprises at least one condensation droplet holding surface formed in the refrigerating compartment.

According to a preferred embodiment of the subject utility model, there is thus provided at least one vertical cold air circulation duct arranged on the rear wall of the refrigerating compartment, wherein the fluid communication aperture is provided on said vertical cold air circulation duct; and at least one horizontal rib is arranged along the vertical cool air circulation duct.

Drawings

The discussed utility model is shown in detail on the basis of fig. 1.

Figure 1 schematically shows the rear wall of the refrigerating compartment of a refrigerator, object of the present invention.

Detailed Description

As shown in fig. 1, the subject utility model discloses a novel refrigerator structure comprising, in addition to other trivial systems known to those skilled in the art, a refrigerating compartment 1 and a cooling unit (not shown) integrating a refrigerant fluid compressor, an evaporator, a condenser, a refrigerant fluid expansion device and a cool air ventilation device. It is emphasized that these elements, as well as other conventional elements omitted from this specification, are part of the current state of the art. Accordingly, the details of construction and/or function of these elements may be deemed well known to those skilled in the art and do not require extensive explanation.

The refrigerating compartment 1 comprises three walls (one rear wall and two side walls) and a door (not shown) and defines a volume in which the circulation of air is generated by the cooling unit.

It is therefore important to underline that said air generated by the cooling unit reaches the inside of the refrigerating compartment 1 through the fluid communication aperture 21, the fluid communication aperture 21 being arranged between the refrigerating compartment 1 and the cooling unit to establish a fluid communication between these two environments.

Preferably, but not limitatively, the refrigerating compartment 1 comprises on its rear wall a vertical duct 2 for circulation of cold air. In the present embodiment, the fluid communication apertures 21 are all arranged on the vertical duct 2 such that the cold air generated by the cooling unit first occupies the entire volume of the vertical duct 2 and then is also ejected through the fluid communication apertures 21.

The greater technical advantage of the discussed utility model means that the refrigerator disclosed herein also comprises at least one horizontal rib 3 arranged on the wall of the integrated refrigerating compartment 1.

These horizontal ribs 3 each comprise a condensation droplet retention surface formed inside the refrigerating compartment 1.

This means that any condensation droplets temporarily accumulate on the surface of the horizontal ribs 3, rather than flowing down to the lower region of the refrigeration compartment 1.

Considering that said horizontal ribs 3 are arranged in the vicinity of the fluid communication aperture 21, the cold air flow generated by the cooling unit eventually dries the condensate droplets before they accumulate and contact the food product.

Preferably, but without limitation, the horizontal ribs 3 are arranged along the vertical ducts 2 and can therefore be made during the thermoplastic injection of the rear refrigerating compartment 1, said rear refrigerating compartment 1 having foreseen the incorporation of the vertical ducts 2.

It is also preferred, but not limiting, interesting to emphasize that in the case of the presence of shelves 4 arranged inside the refrigerating compartment 1, it is desirable to have horizontal ribs 3 above and below each shelf 4, since the greater the number of horizontal ribs 3, the more easily the condensation drops arranged on the retaining surfaces of the horizontal ribs evaporate.

Having described and illustrated a preferred embodiment of a constructive arrangement incorporated in a reciprocating compressor valve, it should be understood that the scope of protection concerned may encompass other possible variants, being limited only by the content of the claims which include feasible equivalents.
