Embodiment Construction

[0090] See attached picture, figure 1 A standard front-loading refrigerator 1 is shown with an open front 2 and a plurality of shelves 3 . The refrigerator 1 comprises an air curtain system having an air outlet 4 located above the open front of the refrigerator and a return air inlet 5 located below the outlet 4 at its top.

[0091] There are various other components of air curtain systems, but such systems are well known in the art, so further discussion of it is not deemed necessary.

[0092] The air curtain system of the refrigerator 1 is suitable for making the air curtain of cooling air blow between the air outlet 4 and the return air inlet 5 , so that the air curtain blows in front of the shelf 3 to improve the efficiency of the refrigerator 1 .

[0093] The air outlet 4 has an outer edge 9 , so that the air curtain discharged from the air outlet 4 has its front edge substantially aligned with the outer edge 9 immediately after leaving the air outlet 4 .

Abstract

A refrigerator has an open front and an air curtain system having at least one upper air egress with an outer edge and at least one lower air-recovery ingress. The air curtain system is adapted to produce a substantially vertical air curtain over at least part of the open front of the refrigerator. The refrigerator comprises at least one shelf between the egress and the ingress, the shelf having a front edge, and at least one elongate air-guiding strip extending across at least part of the open front of the fridge. The strip is located substantially in the plane of the shelf and spaced from the front edge of the shelf. The strip is located substantially vertically beneath the outer edge of the upper air egress.

Description

technical field [0001] The present invention relates to the improvement of refrigerators. Background technique [0002] Front-loading freezers are used in a variety of commercial settings, especially in supermarkets and grocery stores. The purpose of a front-loading freezer is to allow customers easy access to the refrigerated goods stored therein, which may be especially advantageous in high-traffic stores because of the ease of retrieval and loading. [0003] However, a significant disadvantage of front-loading refrigerators compared to refrigerators with closable doors is that their energy efficiency ratio is very low. [0004] One of the ways to reduce the high energy costs of such front opening installations is to install doors or plastic strips which completely cover the opening. But such an addition defeats the whole purpose of the front loader and is a hindrance to shoppers. [0005] Another prior art method for reducing the high energy costs of such front opening...
