Abstract

1414743 Open top display cabinets LINDE AG 21 Feb 1973 [22 Feb 1972] 8389/73 Heading F4H An open-top refrigerating goods storage unit includes a fixed goods container 2 and a removable goods container 3 spaced from the container 2 so that cold air passing over an evaporator 5 may also flow within the space 8 between the two said containers. A minor proportion of the cold air also passes across the unit from an outlet orifice 13 to an inlet orifice 14. When the container 3 is removed, baffles 21 direct all the air across the top of the unit (Fig. 2, not shown). The inclusion of a removable container 3 decreases the direct refrigerating ability of the unit and enables various food stuffs requiring differing cold temperatures to be stored in the unit without loss of moisture. [GB1414743A]

Claims

1. . An open refrigerating goods storage unit. of the type comprising one or more fixed open goods containers permanently installed in the unit and a cool air section for cooling said open goods containers comprising cooled air channels, at least. one vaporiser, a fan for conveying a stream of air cooled by the vaporisation of a refrigeran in' said vaporiser through said cooled air channels around said fixed goods container or containers, and, ..if desired, a defrosting heating unit, wherein at least one of said fixed goods containers is provided with a removable additional inner goods container which forns together with the fixed goods container a channel for the passage of cooled air, said channel constituting together with the other air channels a cooled air circuit.

2. A refrigerating unit as claimed in Claim 1 wherein said channel, together with further cool air channels, forms a circuit for a major part of said cooled air stream, which major part flows only around the walls of said inner goods container or containers, and wherein outlet orifices and inlet/ orifices having relatively small flow cross-sectional areas for the minor part of said cooled air stream are arranged in one or more of the cooled air channels and are directed towards the or each respective opening in the removable inner goods container or containers 41595/2

3. A refrigerating unit as claimed in Claim 2 wherein the cooled air channel defined between the fixed goods container and the revmovable inner goods container lies between the removable inner goods container and said vaporiser, said fan, and where present, said defrosting heating unit.

4. A refrigerating unit as claimed in any one of the preceding claims, wherein, when the inner goods container is removed, the cool air system comprises cooled air channels having outlet orifices directed towards the opening or openings in the fixed goods container or containers, whereby the whole of said cooled air stream is caused to flow both around the walls of said fixed goods container or containers and also across the opening or openings therein.

5. An open refrigerating goods storage unit, substantially as described hereinbefore, with reference to and as shown in the drawing.
