Definitions

  • This invention relates to a refrigeration cabinet suitable for storing dairy products on a wheeled carrier.
  • Such cabinets are convenient because they permit ready stocking and restocking by simply wheeling suitable carriers into and out of the storage space.
  • the efficiency of known cabinets of this type is however significantly limited by the relatively poor air flow patterns which result in uneven cooling and loss of chilled air resulting in high energy consumption.
  • the present invention provides a refrigeration cabinet suitable for storing dairy products on a wheeled carrier, said cabinet having opposed side walls,,a rear wall and a roof defining a storage space and provided with a refrigeration unit and air flow generation means arranged for circulating in use, chilled air from the refrigeration unit downwardly through and to the front of said storage space, wherein is provided a detachable upwardly extending skirt means at the base of the front of said cabinet and wherein said air flow generation means includes duct means having an inlet in proximity to the rear of the base of said skirt and extending rearwardly from said inlet substantially below said storage space to the rear of said storage space whereby in use of the device chilled air is circulated downwardly across the front of the storage space and then under the storage space.
  • a refrigeration cabinet 1 comprising opposed side walls 2, a rear wall 3 and a roof 4 defining a storage space 5.
  • a cooler unit 6 is mounted in the roof 4 in series with air flow generation means comprising suitable fans 7,8 and ducting 9.
  • the ducting includes rear wall ducting 10 extending upwardly along the back wall 3 from a fan 8 at its base to a fan 7 at its upper end, and roof ducting 11 arranged for conveying air through the refriger-- ation unit 6 to a downwardly directed cold air outlet 13 at the front 14 of the cabinet 1 arranged to provide a cold air 'curtain'.
  • a downwardly directed ambient air outlet 12 Imemdiately in front of the cold air outlet 13 is provided a downwardly directed ambient air outlet 12 through which is forced air by a fan 29 whose intake is at the top of the front 14 of the cabinet.
  • This form of double curtain of air flows is itself known in the art.
  • flows of cold air may be employed to provide additional local cooling.
  • One such flow extends below the cooling unit 6 down the back of the storage space 5 to a forwardly directed duct 31 approximately one third of the way down the space 5.
  • a skirt means 16 in the form of a lightweight plastics material provided with suitable engaging means formed and arranged for inter-engagement with corresponding engagement means (not shown) on the side walls 2 for releasable fastening of the skirt means 16 in position at the front of the cabinet.
  • the skirt means 16 comprises a front wall 17 extending upwardly from the base 18 of the cabinet above the lowermost part of the storage space 5. Behind the front wall 17 are two downwardly extending tapering front ducts 19 whose rear walls 20 stop short of the cabinet base 18 to provide rearwardly directed outlets 21 which line up with the inlets 22 of two spaced apart rearwardly extending floor ducts 23 having outlets 24 which line up directly with the rear wall dueting 10 or indirectly via the fan 8.
  • the floor ducts 23 are defined at their base by the floor 25 on which the cabinet stands and at the sides and top by sheeting of suitably formed material, preferably a relatively durable and hygienic material such as stainless steel whereby the parts 26 of the sheeting to either side of the floor ducts 23 which parts rest on the floor 25 can support wheeled carriers 27 which can be safely driven repeatedly over said parts 26.
  • the storage space 5 is formed and dimensioned to receive a pair pf wheeled dairy produce carriers 27 side by side (only one visible) as well as a pair of adjustable shelves 28 for additional produce above the carriers 27.
  • the refrigeration cabinet construction is substantially conventional with the outer walls generally being insulated where possible and easily cleaned e.g. moulded plastics materials being used wherever possible on the inside in and around the storage space.
  • a chilled air curtain is directed downwardly across the open front of the cabinet (as shown by the arrows F) into the skirt ducts 19 and then through the floor ducts 23.
  • the chilled air flow is carried right around the front and bottom of the storage space 5 so that a proper cooling of the whole of -it is obtained.
  • the ready access of wheeled carriers in and out of the storage space is substantially unaffected.
  • a refrigeration cabinet according to any one of claims 1 to 4 wherein the rearwardly extending duct means (23) is formed and arranged to extend between wheel track pathway means (26) of a respective said wheeled carrier (27).
  • a refrigeration cabinet according to any one of claims 1 to 5 wherein the airflow generation means includes rear wall ducting (10) extending upwardly along the back wall (3) to roof ducting (11) having a downwardly directed outlet (13) at the front of the cabinet (1).
