Definitions

  • the invention relates to a display cabinet for holding ready-to-eat food and maintaining the food at a suitable hot or cold temperature.
  • the display cabinet is intended to hold and display hot ready-to-eat food such as cooked chickens, pastries and ethnic snacks.
  • One known kind of display cabinet comprises a deck having apertures therein and stainless steel Bain Marie bowls depending from the deck through the apertures. Beneath the deck is a rod element which heats the bowls. A thermostat arranged in the heated region controls the operation of the rod element which, when switched on, operates at constant temperature.
  • the display cabinet comprises a hood extending over the bowls, the hood having high power halogen lamps which both illuminate the food and provided a supplementary source of heat for the food.
  • US-A-4,990,749 describes a Bain Marie cabinet where heated water is arranged to heat a plurality of bowls in the cabinet. The use of water to heat bowls in that way is not ideal as the heated water can be a source of bacteria and there are associated cleaning and maintenance problems.
  • a deck of the display cabinet has a Bain Marie bowl arrangement similar to the above cabinet. Under the deck, forced air heaters circulate air to heat the bowls and hence the food. Further apertures are provided in the deck and the hot air passes through the further apertures to create a hot air environment above the deck which heats the food. A thermostat arranged below the deck controls the heaters.
  • a further kind of known display cabinet has a deck in the form of a hot water reservoir which is heated from below by a known heating element. Bain Marie bowls sit in the reservoir and are thus heated by the reservoir. Steam evaporated from the reservoir passes through spaces defined by the bowls to communicate with the region above the deck to create a hot wet atmosphere which heats the food. A thermostat in the water controls the heaters. Again, the use of water to heat bowls in that way is not ideal
  • One object of the present invention is to provide a display cabinet which reduces that problem.
  • a display cabinet for holding ready-to-eat food on a deck comprising a plurality of zones for the food, in which the zones can be temperature controlled independently.

  • the combination may be in the form of a one piece heating member.
  • the heating member is moveable away from the deck to allow cleaning of the heating member, most preferably, the heating member is pivoted about a hinge position towards an edge of the deck. In that way, the heating member can be cleaned without removing the heating member from the display cabinet.
  • the plurality of independent heating elements may be separated simply by leaving a space between adjacent heating elements or, preferably, by extending the epoxy resin layer into a space between adjacent heating elements.
  • the plurality of zones are preferably temperature controlled by an electronic controller.
  • the controller preferably controls the plurality of zones through respective relays.
  • the controller preferably has selector means by which a given zone can be heated to a temperature which is correct for a give type and/or quantity of food to be displayed.
  • the controller has a control panel on which the selector means is mounted.
  • the display cabinet preferably comprises a plurality of timers, each of which corresponds to an area of the deck, most preferably each timer being positioned in line which vertically coincides with the corresponding area of the deck. In that way, the progress of food on a particular area of the deck can be followed.

  • Fig. 1 shows the infrared heaters 36 are located above Zone B and tends to heat Zone B more than Zones A and C.
  • the halogen lamps 35 are located above Zone C and tend to heat Zone C more than Zones A and B. Due to the greater heating of Zones B and C by respectively the infrared heater 36 and the halogen lamps 35, the heating elements 24, 26 corresponding to those Zones B and C need be heated to a lesser extent than Zone A. In some cases (for example when heating carvery food) it may be necessary to heat only the heating element 22 corresponding to Zone A and rely on the infrared heating arrangement 36 and the halogen lamps 35 to heat Zones B and C respectively. When using Bain Marie bowls it is necessary to heat all the Zones A, B, C with the heating elements 22, 24 and 26.

  • lateral edges 107a of the receptacles 107 rest on respective upper surfaces 108 of the side members 106 such that the main body 107b thereof is suspended on the frame 100.
  • the side members 106 are further formed so as to define channels 110.
  • the channels 110 enable ⁇ the frame 100 to be slidably located within a display cabinet.
  • the end member 102 is provided with a folded handle 112. Projecting tangs 114 of the end member 102 provide a location for the side members 106 to be welded there to and further serve to enhance the structural rigidity of the completed frame 100.
  • the channels 110 of the side members 106 are adapted to co-operate with guides provided on a display cabinet primarily of the kind shown in Fig 1 and indicated at 10 in Fig 25.
  • Figs. 21 to 24 show an embodiment of such a guide generally designated 116.
  • the guide 116 is generally "T" shaped and comprises a stem 118 having laterally extending lips 120.
  • the base 122 of the stem 118 is provided with two threaded apertures 124 which enable the guide 116 to be secured to a wall 117 of the display cabinet 10 by the use of appropriately screw threaded fasteners 119.
  • the display cabinet is provided with two guides 116 in a rear portion thereof, which guides 116 are spaced so as to correspond to the spacing of the channels 110 of the frame 100.
  • the folded longitudinal edges 126, 128 defining the channel 110 of each side member 106 are not of equal length, with the result that the lower edge 128 terminates before the end member 102.
  • This configuration enables the lips 120 of the guides 116 to be readily introduced into the channels 110, Fig 25 showing the way in which the lips 120 of one of the guides 116 locate in a corresponding channel 110 of the frame 100.
  • the guides 116 and channels 110 co-operate slidably so as to enable the frame 100 to be slid out from the rear of the cabinet on the guides, for example to enable the gastronorms supported thereon to be replaced and/or replenished.
  • the rearward movement of the frame 100 relative to the display cabinet is limited by folded stops 130 of the side members which serve to close the channels 100 at the front member 104.
  • the channels 100 and guides 1 16 co-operate to support the frame 100 in a cantilevered manner, the stops 130 limiting the extent of rearward movement of the tray by contact with the guides

Abstract

L'invention concerne un présentoir vitré servant à contenir des aliments prêts-à-manger, comprenant un plateau (14) sensiblement plat et des éléments chauffants (22, 24, 26) destinés à chauffer les zones A, B, C correspondantes du plateau. Les éléments chauffants (22, 24, 26) peuvent fonctionner indépendamment de façon à chauffer une zone du plateau indépendamment d'une autre, et à chauffer par en dessous les récipients (32) pour aliments situés dans ces zones. Ainsi, il n'est plus nécessaire de chauffer tout le plateau (14), les récipients (32) pour aliments n'occupant qu'une partie du plateau. Un chauffage supplémentaire peut se présenter sous la forme d'un dispositif chauffant (36) infrarouge à impulsions qui chauffe les aliments contenus dans les récipients (32) par en dessus. Les récipients pour aliments peuvent avoir comme support des structures (100) coulissantes permettant d'avoir accès aux aliments dans les récipients sans avoir à les chercher à l'intérieur du présentoir.
