Benefits of technology

[0007]Each end of the second fan system is several inches shorter than the display case to allow for case to case attachment. The second fan system includes a louver near each of the side walls and a front of the second fan system. Each louver includes a plurality of slanted panels. The louvers direct the ambient air towards the side walls of the display case to improve the secondary discharge air velocity in a front corner area of the display case.

Problems solved by technology

A drawback to prior display cases is that the flow of ambient air is restricted towards the side walls of the display case, reducing the supply and velocity of ambient air at both ends of the display case.

Embodiment Construction

[0016]FIG. 1 illustrates a supermarket display case 10 or merchandiser. The display case 10 cools or refrigerates products 12 and presents the products 12 to customers in an appealing manner. The products 12 can be produce, dairy products, meat products, or any other refrigerated product. The display case 10 includes shelves 36 that hold the products 12.

[0017]The display case 10 includes a first fan system 14 that circulates cool air through the display case 10 to cool the products 12 to a desired temperature. The display case 10 includes a fan blade 84 and a fan motor 86 located in a lower section 16 of the display case 10 that draws air through a return grille 18. The air is forced through an evaporator coil 20 (part of a refrigeration system including a compressor, not shown) that cools the air to a desired temperature. The cooled air flows upwardly through a rear duct 22. Part of the air moving up the rear duct 22 also diffuses into an interior display volume 30 of the display c...

Abstract

A display case cools and displays products. A first fan system circulates cool air through the display case. The cool air is directed downwardly along a front of the display case to form a primary air curtain. A second fan system circulates ambient air to generate a secondary air curtain. The secondary air curtain is located between the primary air curtain and the outside environment, trapping the primary air curtain near an interior display volume of the display case. Each end of the second fan system is several inches shorter than the display case to allow for case to case attachment. The second fan system includes a louver near each of the side walls and a front of the second fan system. Each louver includes a plurality of slanted panels. The louvers direct the ambient air towards the side walls of the display case to improve the secondary discharge air velocity in a front corner area of the display case.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates generally to a display case including a fan system having deflectors that direct ambient air towards side walls of the display case to improve the discharge air velocity of the ambient air in a front corner area of the display case.[0002]Refrigerated food and beverage display cases (or merchandisers) are commonly used in grocery stores or supermarkets to cool refrigerated products and present the products to customers in an appealing manner. A first fan system generates a first air curtain that cools the products in the display case. A second fan system generates a second air curtain that reduces the entrapment of ambient air in the display case.[0003]Several display cases can be attached side by side. The second fan system is several inches shorter than the display case at each side to allow for case to case attachment. A drawback to prior display cases is that the flow of ambient air is restricted towards the side wall...
