Definitions

  • the invention relates to a refrigerator with a furniture body, which contains a goods room and facilities for cooling and circulating a cooling air flow.
  • Refrigerated cabinets of the type mentioned are used in particular as refrigerated counters or refrigerated shelves in wholesale markets and retail stores.
  • the goods room contains a storage area on which goods are presented for sale.
  • a cold air stream is routed through the goods room continuously or at intervals.
  • the cold air flow is generated by means of a device for air circulation, for example a radial fan or fan, which sucks in air from the environment or from the goods room and conveys it into the goods room, the air being cooled in a cooling device before entering the goods room.
  • the devices for cooling and circulating the air are located below the storage surface in the furniture body.
  • the inside of the furniture body must be cleaned from time to time in order to remove impurities, for example blood running down from meat counters, or to wipe up any cleaning liquid that drips down when cleaning the shelf.
  • impurities for example blood running down from meat counters
  • the internals that are located below the storage surface namely the devices for cooling and circulating the cooling air
  • the internals are very cumbersome. Since the internals often have sharp edges, there is also injury to the personnel performing the cleaning work. For this reason, it has already been proposed to fix the device for air circulation arranged under the storage area to the underside of the storage area, so that it is lifted out of the furniture body for cleaning when the storage area is opened (EP-A-16 402).
  • the invention is therefore based on the object to develop a refrigerator of the type mentioned, in which the furniture body is easy to clean.
  • This object is achieved in that the devices for cooling and circulation are arranged on the back of the goods room.
  • the furniture body is completely free from interfering fixtures, so that the furniture body is freely accessible for cleaning work.
  • Another aspect is the possibility of arranging the storage area deeper than before, so that the volume of the goods space is increased.
  • the device for cooling is composed of sections having fins and the device for circulating is located between the sections.
  • the arrangement of the devices for circulating and cooling according to the invention causes a shortening of the goods space, which is undesirable in many cases. If, according to the further development proposal, the device for circulating is now housed between two sections of the device for cooling, the two devices are essentially in one plane, i.e. the two devices together do not take up more space than the cooling device.
  • the device for cooling is arranged on the exhaust air side of the device for circulating in the cooling air flow.
  • the cooling device has flow openings for cooling air in its upper and lower region and is closed on its sides. This arrangement requires the cooling air flow to flow perpendicularly through the cooling device. It is conveniently located above the cooling device an air outlet opening into the goods room.
  • the device for circulating is arranged in a flow channel which is open at the bottom and which is connected to a flow channel for the cooling air flow located below the goods space.
  • the flow channel which contains the device for circulating, is closed towards the front from the goods room located in front of the device for circulating.
  • the flow path below the goods room is preferably limited by the furniture body on the one hand and by the storage surface on the other.
  • the intermediate space containing the device for circulation is closed on the sides and at the top and is open towards the underside of the device for cooling.
  • the cooling air flow is first led downward and passed through the cooling device from bottom to top.
  • Two of the side walls can be formed by evaporator fins of the sections of the device for cooling which adjoin the intermediate space on both sides.
  • the devices for circulating and cooling are arranged below a worktop for sales personnel.
  • a fan is provided as the device for circulating.
  • the refrigerated counter according to FIG. 1 contains a furniture body 2 and an attachment 3 on a base 1.
  • the attachment 3 has a front pane 4 on the side facing the buyer.
  • a storage surface 6 is inserted, which, in conjunction with a rear air baffle 7 and a front grille 8, forms a goods space 9 in which goods are offered for sale.
  • the refrigerated counter is used, for example, to offer meat and sausage products, cheese, salads, delicatessen, etc.
  • an evaporator 10 for cooling At the rear of the goods room 9 there is an evaporator 10 for cooling and a fan 11 for circulating cooling air.
  • the fan 11 is, as can be clearly seen from FIGS. 3 and 5, inserted in an intermediate space of the evaporator 10, so that its front edge is approximately flush with the front edge of the evaporator 10. In this way, the space required for the evaporator and fan is minimal.
  • a partition 12 is provided between the evaporator 10 and the fan 11 and has an opening in the area of the fan 12.
  • the one containing the fan 11 Air duct is closed at the top by a cover 13, while at the bottom it is openly connected to an air flow path formed between the storage surface 6 and the furniture body 2.
  • the evaporator 10 has flow openings for air in its upper and lower region. In the area of the air outlet openings there is an opening 14 in the goods room.
  • the air flow in the refrigerator is illustrated by arrows 15. More precise details of the air flow can be found in FIGS. 2 to 5.
  • FIGS. 2 and 3 as well as 4 and 5 show two different embodiments of the evaporator 10.
  • two fans 11 are provided in each case, depending on requirements, just one fan or a larger number of fans could also be provided.
  • the evaporator according to Figures 2 and 3 contains cooling tubes 16 in which a coolant is guided. Slats 17 are arranged transversely to the cooling tubes 16. The fins are interrupted at two points, so that the evaporator has three sections 10a, 10b, 10c. The gaps 18, 19, which are formed between the sections 10a, 10b, 10c, are sealed off on the sides. The fans 11 are inserted into the spaces 18, 19.
  • the front of the evaporator is closed by the partition 12, which has circular openings only in the area of the fan blades.
  • the evaporator thus has air passage openings only on its lower and on its upper side.
  • the gaps are through the cover 13, the partition 12 and the sides walls on the sections 10a, 10b, 10c of the evaporator closed, so that the air flow is deflected downward, from where it is distributed over the underside of the evaporator.
  • the air flow flows through the evaporators from bottom to top, cooling down. The cold air flow is then directed into the goods room.
  • Figures 4 and 5 differ from Figures 2 and 3 only in that instead of an evaporator with continuous cooling tubes three sections with separate cooling tube sections 20a, 20b, 20c are provided.
  • the other components correspond to those in FIGS. 2 and 3.
