  • display unit 10 constructed in accordance with one embodiment of the present invention.
  • display unit 10 includes a main display housing or bin 12 having an enclosed display area 13 defined by bottom wall 14, rear wall section 16, opposite side members 18 and 20, and first and second transparent covers 22a and 22b which can be separately pivotally secured to rear wall section 16 by one or more hinges (not shown) , or slidably secured to rear wall 16 and bottom wall 14 by elongated slots (not shown) positioned in the upper interior edge of rear wall 16 and the front interior edge of bottom wall 14.
  • a strip of rigid material 21 is included which extends from the upper interior edge of rear section 16 to the front interior edge of bottom wall 14 for providing support for a lateral edge of each transparent cover.
  • covers 22a and 22b and side members 18 and 20 are preferably manufactured from a transparent, lightweight material such as plexiglass.
  • a lightweight material is desired to enable the consumer to lift or slide the covers without undue exertion.
  • cover and side members are preferably made from the same material for aesthetic purposes, it should be readily appreciated by those skilled in the art that different materials may be used.
  • transparent covers 22a and 22b collectively define front and upper interior surface portions 23 and 25 of the enclosed display area, respectively.
  • Side members 18, 20 and covers 22a and 22b are preferably configured as individual components to keep the weight of the cover to a minimum.
  • a suitably lightweight material having the desired degree of transparency it is also possible to construct a single cover having the side members integrally provided thereon, or alternatively, to integrally form side members 18 and 20 as part of individual covers 22a and 22b, respectively.
  • suitable gaskets may be utilized where appropriate to prevent leakage of refrigerated air from the enclosed display area. As more clearly shown in FIG.
  • rear wall 16 there is disposed immediately behind rear wall 16 a refrigerated air supply plenum 24 which extends transversely preferably the full width of the main display housing 12.
  • rear wall 16 is a common wall separating plenum 24 from the interior of the display area. Passage of refrigerated air from plenum 24 into the display area is thus facilitated by a plurality of elongated apertures or slots 26 defined in rear wall 16 (FIG. 1) .
  • display unit 10 utilizes a conventional, thermostat- controlled refrigeration system 28.
  • a conventional refrigeration system includes a compressor, a condenser, a liquid tank, an expansion valve or capillary tube, an evaporator, and an accumulator, all connected in series. Because such systems have long been in use and are deemed to be very well known, a detailed illustration and description of the operation thereof has been omitted herein.
  • the exterior of main display housing 12 includes exterior side walls 36 and 38, upper wall 40, rear wall 42, and a bottom wall (not shown) . Collectively these walls define a back chamber 44 for accommodating evaporator portion 30 and plenum 24.
  • chamber 44 essentially defines a return air plenum communicating with evaporator portion 30 in order to re-cool and re-circulate air within the enclosed display area.
  • a plurality of return air intake openings 47 are formed in bottom wall 14 (FIG. 1) .
  • Arrows A, B, and C signify the direction of air flow, with arrow A showing the flow of spent or warm air after it has passed over grocery products (not shown) disposed in the display area of unit 10.
  • the air is recirculated in the direction of the arrows by evaporator fan 32.
  • additional fans may be placed in other areas of chamber 44 or within the plenum itself, in order to ensure a uniform flow pattern.
  • the warmer returned air is diverted upward, as shown by arrow B, between the outer housing rear wall 42 and the evaporator portion 30.

  • display unit 10 further includes a remote housing 48 for accommodating the remainder of refrigeration system 28, including the compressor 49 and condenser 51. Placing the condenser, compressor and other elements of the refrigeration system in remote housing 48 reduces the overall size of the system and permits easier access for recharging of refrigerant and other maintenance or repair operations which must typically be performed on such systems. Also provided are first and second fluid connection lines 50 and 52 for supplying refrigerant between the evaporator, compressor, and condenser components. For a purpose which will now be explained, the fluid connection lines are preferably configured as hoses and are made of a flexible material compatible with the refrigerant material being conveyed.
  • the main display unit housing can be positioned on any counter or on any shelf which provides sufficient overhead clearance to enable upward pivoting of the cover.
  • the cover can be alternatively configured as one or more sliding doors.

  • FIG. 4 there is shown a typical installation in which main display housing 10 is positioned on an uppermost shelf 54 and remote housing 48 on the base shelf 56 of a gondola display rack system 58. It will, of course, be understood that if space permits, the remote housing may be placed on the same shelf as the main unit, or even suspended directly above the main unit. In any event, it will be readily apparent to those skilled in the art that the flexibility of hoses 50 and 52 permits a wide variety of arrangements which would not be possible if the hoses were constructed of metal or other rigid materials.
  • FIG. 5 there is shown a slightly modified embodiment of the display system of the present invention. Specifically, there are shown first and second main display housings 100 and 102, which are each constructed in an identical manner to that described above in connection with housing 10. However, rather than utilizing independent remote housings as remote housing 48 discussed above, the embodiment depicted in FIG. 5 utilizes common compressor and condenser sections
  • each main display housing located in a single housing 146.
  • the evaporator sections (not shown) of each main display housing are connected to the common compressor and condenser sections by flexible hoses 150a, 152a and 150b and 152b, respectively, in a manner similar to that described above except that suitable means, such as corresponding "T" connectors (not shown) , must be utilized to connect hoses 150a, 150b and 152a, 152b to the common compressor and condenser sections, respectively.
  • FIG. 6 there is illustrated a display unit 210 in accordance with another embodiment of the present invention.
  • the construction of the embodiment presented in FIG. 6 is, in every material respect, identical to the embodiment depicted in FIGS. 1-4, except that instead of utilizing a remote housing and the flexible refrigerant connections attendant therewith, compressor 249 and condenser 251 are disposed within a second chamber 268 separated from chamber 244.
  • an insulating barrier 270 is preferably provided therebetween.
  • chamber 268 is shown positioned beneath chamber 244, it may, in fact, be positioned over the top, or adjacent the side walls, of chamber 244, if desired. Referring now to FIGS.
