Definitions

  • Refrigeration appliance body with air duct
  • the present invention relates to a body for a refrigeration device.
  • a body for a refrigeration device.
  • Such a body is conventionally constructed of a molded from plastic sheet material inner container, an outer skin of sheet metal or plastic plates, and insulating foam material, which fills a gap between the inner container and the outer skin.
  • an evaporator is housed in a chamber separated from the interior, and the interior is cooled by circulating air between the chamber and the interior.
  • a distribution channel is provided, which serves to distribute cold air from the chamber over at different points in the interior to dispense exhaust openings in the interior or deduct from different locations and supply the chamber.
  • a combination refrigerator with a freezer compartment 15, a zero-degree compartment 16 and cooling compartments 17, 18 is known in which the evaporator chamber is housed between the freezer compartment and the zero-degree compartment 16, an air duct 27 itself extends in the rear wall of the device from the zero-degree compartment 16 to the cooling compartment 17 and air ducts 26 extend in the side walls of the device from the zero-degree compartment 17 to the evaporator chamber.
  • These channels are each embedded in the insulating foam layer. Since the sometimes complicated shaped channels must be prefabricated as individual parts and must be mounted at their ends in each case closely fitting in the inner container cut openings, the assembly of this refrigerator is complex and costly.
  • DE 101 43 242 A1 describes a refrigeration device in which a cold air duct is formed on the inside of the inner container. It extends along the ceiling and the door of the refrigerator. During the running on the inside of the door part of the channel the usable Volume of the interior hardly affected and also has the advantage of being able to serve as a holder for door racks, affects the running on the ceiling channel noticeably the uses of the upper portion of the interior. If you were to place a channel with the DE 101 43 242 A1 on the rear wall of the inner container, the restrictions would be even more serious.
  • the object of the invention is to provide a body for a refrigeration device, in which an air duct is simple and inexpensive to install, without significantly affecting the potential uses of the interior.
  • the object is achieved by a body with the features of claim 1.
  • B. deep-drawn groove is disposed of, eliminating the need to project a channel delimiting the interior of the cover plate far and disturbing in the interior to realize a required channel cross-section.
  • serving as an air duct groove is embedded in its closed-walled groove sides in the heat insulating material of the refrigeration unit body and thus simultaneously thermally insulated.
  • the supernatant of the cover plate is smaller than the depth of the groove via adjacent to the groove wall portions of the inner container.
  • the supernatant can be set to zero, so that the grooved inner container wall and the cover plate give a flush surface. In this case, for a wide distribution of air flowing out of openings of the cover plate, it may be advantageous to provide the openings with differently oriented guide blades.
  • cover plate may well be desirable; on the one hand, because the thermoforming technique used to form the inner container can lead to scattering dimensions of the groove, which make a precisely flush attachment of the cover plate difficult; on the other hand, flanks of the cover plate which project beyond the container wall permit the attachment of outflow openings aligned in different directions.
  • the cover plate is preferably provided with edge strips which rest against adjacent to the groove wall portions of the inner container.
  • cover plate may be provided by her projecting and applied to side walls of the groove webs.
  • FIG. 1 shows a schematic vertical section through a refrigerator body according to the invention.
  • Figs. 2 to 6 are each a horizontal section through a channel of the refrigerator in various configurations.
  • FIG. 1 shows a refrigerator body with an outer wall 1, a deep-drawn inner container 2 and an enclosed between both Isolierschaum Mrs 3.
  • the inner container defines two compartments, an upper compartment or freezer compartment 4 and a lower compartment or normal refrigeration compartment 5.
  • An intermediate wall between the compartments 4, 5 contains a chamber 7, in which a not shown evaporator is housed.
  • a groove 7 or 8 is formed in each case during deep drawing, which extends vertically from the intermediate wall 6 from.
  • the two compartments 4, 5 can be formed together with the outer skin of the intermediate wall 6 during deep drawing of the inner container; In this case, at the ends of the grooves 7, 8 at the level of the intermediate wall 6 in each case an opening in the inner container 2 is cut, and the two grooves are connected by a foam side inserted, communicating with the chamber 7 channel portion 9.
  • the two grooves 7, 8 continuously merge into one another at the level of the intermediate wall 6, and it is not necessary to cut an opening in the inner container in order to establish a connection between the chamber and the channels.
  • Controlled flaps disposed at the grooves 7, 8 at the level of the intermediate wall 6 for selectively supplying cold air from the chamber 7 into the groove 7, the groove 8 or both at the same time are omitted in the figure.
  • a cover plate 10 and 11 The grooves from the interior of the compartments 4, 5 each delimited by a cover plate 10 and 11 respectively.
  • the cover plates are provided in the embodiment considered here at intervals with outflow openings 12.
  • a closed cover plate could also be used to guide an air duct past a first compartment to a second, without air in the first To give a subject.
  • FIG. 2 shows a section along the line designated X-X in FIG. 1 according to a first embodiment.
  • the groove 8 has a flat rectangular cross section and, together with the cover plate 11, defines an air channel 13, through which air is guided from the chamber 7 to the compartment 5.
  • the outflow openings 12 lying in the sectional plane are provided with guide lamellae 14, which divert the discharged air flow respectively out of the sectional plane of FIG. 1 out to the right or left.
  • the cover plate 11 is here arranged flush with the groove 8 surrounding areas 15 of the inner container rear wall. It is held in this position by webs 16 which project from the longitudinal edges of the cover 11 protruding into the interior of the groove 8, are clamped between the side edges 17 and are supported on the bottom 18 of the groove 8.
  • FIG. 1 shows an embodiment with protruding cover plate 11; the supernatant is large enough here that discharge openings 19 can be provided on the webs 16 anchoring the cover plate 11. Air flowing out of these openings 19 initially flows along the rear wall of the inner container and thus distributes itself over the width of the compartment 5, without any refrigerated goods flowing directly to it.
  • the webs 16 are shortened compared to the embodiment of FIG. Laterally projecting nubs 20ververasten the cover plate 11 by engaging in recesses on the flanks 17 of the groove 8.
  • laterally projecting edge strips 21 are integrally formed on the webs, which cover the adjoining the groove 8 edge portions 15 of the rear wall a piece and thus complete a gusset 22 and protect against contamination, which is characterized by a rounded transition between the rear wall and the side edges 17 of the groove results.
  • a transition strip 23 is set back by a depth between the groove 8 and the adjacent regions 15 of the rear wall, which corresponds to the thickness of the edge strips 21 of the cover plate 11 protruding laterally beyond the webs 16.
  • a locking of the webs 16 on the side edges 17 of the groove an exact flush of the cover plate 11 with the rear wall is comparatively easy to implement here.
  • the webs 16 are reduced to individual arms 24 which are separated by cutouts.
  • the section of this figure extends in height of two such cutouts.
  • the cutouts act as outflow openings, which are concealed behind the cover plate 11 flush widening, spaced from the rear wall edge strip 20.
