Definitions

  • the present invention relates to a refrigerated sales cabinet.
  • Refrigerated sales cabinets as they are known in the art respectively comprise a cabinet body, side panels, a door frame and at least one hinged door, wherein the side panels are installed on the sides of the cabinet body, the door frame is installed on the cabinet body, the hinged door is installed on the door frame so that it is moveable in a swinging motion, and sealing strips are provided between the cabinet door and the door frame.
  • the door frame comprising a front surface, which is exposed to ambient conditions, is cooled when the refrigerated sales cabinet is operated. If the temperature of the front surface drops below the dew point, humid ambient air condensates at said front surface causing water droplets to appear; this is uncomfortable for the customers. Therefore, there is a desire to prevent the temperature of the front surface to fall below the dew point temperature in order to avoid condensation at said front surface.
  • WO 2014/019625 A1 discloses a refrigerated sales cabinet comprises a cabinet body providing a refrigerated sales space for supporting refrigerated goods to be sold, a door frame having a top post, a bottom post and at least two upright posts, and at least one door.
  • At least one of the posts comprises a cold main body and an insulating front element comprising, from back to front, a rear panel, which is attached to the cold main body, and a front panel forming the front surface of the post.
  • At least one surface of the front panel is covered with a coating employing nano-technology for providing thermal insulation against the cold main body of the post.
  • US 3 508 361 A discloses a pair of sliding doors are mounted in a rectangular door frame having top, bottom and side members. Each door is supported by a pair of grooved rollers which ride along a flange or track projecting upwardly from the bottom member of the frame. Each roller has a shaft with an eccentric mounting stud which can be turned to adjust the elevation of the roller, so that the doors can be aligned with the frame. Each door has a closure spring which is mounted vertically along one of the side members and is connected to the door by a cable which is wrapped around a pulley. The spring and the vertical portion of the cable are enclosed by a removable channel shaped strip which is mounted in the side member of the frame.
  • Each door contains a heater which is supplied with electrical current by a cord connected between the door and the frame.
  • the cord is formed into a u-shape with upper and lower horizontal legs.
  • Horizontal channel members are provided on the frame and the door to retain and conceal the upper and lower legs of the cord so that the cord will be kept out of the way and out of view.
  • a refrigerated sales cabinet is defined in claim 1 and comprises a cabinet body providing a refrigerated sales space for supporting refrigerated goods to be presented therein and a door frame having a top post, a bottom post, and at least two upright posts.
  • At least one of the posts comprises a main body having a constant cross-section including a rear wall portion and two side portions respectively extending forwardly from the rear wall portion, the rear wall portion and at least one of the two side portions being at least partially in contact with refrigerated air; and a front element, a front portion of which being in contact with warmer ambient air.
  • the refrigerated sales cabinet further comprises a hinged door, which is moveable in a swinging motion between an open state providing access to the refrigerated sales space and a closed state shutting the refrigerated sales space, wherein the door is configured to abut, in its closed state, only against a side portion of at least one of the posts.
  • the doors do not contact the front element, which is exposed to warm ambient air and therefore has a higher temperature than the doors, in particular the inner panel of the doors and the side wall portions of the post facing the refrigerated sales space.
  • the formation of a heat bridge which would allow an undesirable transfer of heat from the relatively warm front side of the front element via the doors into the cooled refrigerated sales space, is reliably prevented.
  • the temperature of the front side of the front element remains high and a condensation of moisture form the ambient air on the front side of the front element is reliably avoided.
  • the energy needed for cooling the refrigerated sales space is minimized, as the entry of thermal energy into the refrigerated sales space is considerably reduced.
  • a refrigerated sales cabinet 20 of the front-access type with doors 38 and a door frame 21 according to an exemplary embodiment of the invention is shown in Figure 1 .
  • the refrigerated sales cabinet 20 as shown in Figure 1 comprises a cabinet body 22, a left side panel 30, a right side panel 31, a door frame 21 and a plurality of doors 38.
  • the cabinet body 22 comprises a bottom part 26, a roof plate 24, a rear wall 27 defining a refrigerated goods storage and presentations space (“refrigerated sales space") 29 comprising a plurality of goods presentation shelves 28.
