Definitions

  • the present invention relates to a refrigerator, in particular a household refrigerator.
  • the object of the invention is to provide a refrigeration device in which a risk of moisture condensing on the outside of the housing can be avoided without impairing the energy efficiency of the device.
  • the object is achieved by a collecting channel is attached to an outer surface of the refrigerator in such a refrigerator.
  • a gutter is arranged on the outside of a wall of the device, on the inside of which an evaporator is mounted, that is generally on a rear wall of the device. Since this wall is more strongly cooled by the evaporator from the inside than other walls of the device, it achieves a lower temperature outside with a comparable insulation thickness and is therefore more prone to condensation.
  • the flat material part is preferably bent at a lower edge with its laminated side to the outside to form a drip edge.
  • the water can no longer reach an edge of the lamination, and the flat material part remains dry inside.
  • the bent lower edge jumps behind a main part of the flat material part inside the device.
  • the gutter jumps back against the outer surface of a wall.
  • the wall forms a return for it, in particular in the region of the gutter. It is therefore not necessary to increase the distance between the main part of the flat material part and an opposite furniture or building wall to accommodate the gutter.
  • the gutter therefore does not affect the efficient use of space of the device, and the housing dimensions need to be compared to a conventional refrigerator without the gutter not to be changed.
  • the invention can therefore easily be integrated into existing device concepts, since at most a small part of the housing components of the devices must be modified for carrying out the invention.
  • the gutter is part of a molded part, which further forms a downwardly open groove for receiving an upwardly bent edge of the flat material part.
  • This molding is the only housing part that is additionally required to implement the invention over a conventional refrigeration device.
  • this molding is considerably simplified if it has a hinge, in particular a film hinge, which connects two side walls of the groove.
  • the two side walls of the groove are expediently held together by latching elements.
  • the latching elements can each be provided only at the ends of the groove. However, in order to ensure a secure cohesion over the entire length of the groove, locking elements should be distributed along the groove. In particular, for this purpose, at least one of the latching elements should intersect a cutout in the bent-over edge of the flat material part.
  • a lower edge of the rear wall board may be inserted in a groove of a bottom part of the housing.
  • the molded part expediently has a rib which engages in the groove of the housing part.
  • the wall thickness of the rib is expediently equal to that of the flat material part.
  • the molding can be provided for fixing in the insulating layer extending lines in an insulating layer of the device engaging holder. Since the molded part is advantageously made in injection molding, the additional expense associated with the molding of the holder is low, the installation of the device, however, is simplified, since the otherwise required for attaching the holder operations omitted.
  • a preferred material for the molding is polypropylene, since it is impact resistant and therefore insensitive to assembly and is well suited for the formation of a film hinge. In addition, it is well diffusion-tight against water vapor, so that moisture can not penetrate through the molding into the insulation layer.
  • a condensate drain from a storage chamber of the apparatus preferably opens into the gutter, so that the condensed water from the storage chamber and condensed water collected on the outside of the appliance can be supplied together from the gutter from an evaporation device.
  • a base unit of the refrigerator are housed in the heat-dissipating components such as a compressor and a condenser, below the gutter an air outlet opening can emerge through the hot air and can rise past the gutter. This warm air can reduce the amount of condensed water collected by the gutter.
  • Fig. 1 shows a perspective rear view of a built-in refrigeration appliance according to the invention.
  • the refrigerator has a cuboid housing with a body 1 and a door 2, which define a thermally insulated storage chamber inside, as well as a pedestal unit 3 suspended below the carcass 1.
  • a refrigerator is mounted in a furniture recess of a kitchen appliance by placing in a base plate of the niche a cutout is created through which the base unit 3 dips into a base region of the furniture, while the underside of the body rests on the base plate.
  • the base unit 3 includes a compressor and a condenser and a fan that sucks in through openings on the front of the base unit 3 facing away from the viewer fresh air, blowing on the compressor and the condenser and ejects again. Some of the air heated at the condenser and / or compressor exits via openings 4 in a rear wall of the base unit 3.
  • obliquely positioned guide blades 5 direct the escaping air upward into a space between a rear wall 6 of the body and one of these rear wall 6 in the installed state typically opposite, not shown in the figure furniture. or building wall.
  • the outside of the rear wall 6 consists in a manner known per se essentially of a rectangular cardboard 9 vapor-tightly and watertightly laminated with aluminum foil.
  • the cardboard 9 covers a heat insulating foam layer. Cut edges that form the top and side edges of the carton 9 are bordered on ceiling and side wall panels 7, 8 of the body 1.
  • a central region 10 of the carton 9 projects a few centimeters beyond the edges to the rear.
  • a gutter 11 is inserted into the rear wall 6 to collect condensation, which can be reflected under unfavorable climatic conditions, especially at high ambient temperature and humidity, on the backboard 9.
  • Fig. 2 shows a section through the gutter 11 and its surroundings.
  • the polypropylene molded injection gutter 11 extends over the entire width of the rear wall 6 and is in each case from the sides down to a central drain opening 12.
  • An outer web 13 delimiting the gutter 11 towards the back of the body 1 extends substantially in a same vertical plane as the central portion 10 of the back wall carton 9.
  • An inner wall 14 bounding the gutter to the front of the body 1 leaps in front of the heat insulating foam layer 15, which fills the walls of the body 1.
  • a fork-like holder 16 is formed on the foam side, the two curved fingers of which fix an electrical line 17 extending inside the foam layer 15.
  • a drain channel 18 extends, which starts from the lowest point of a collecting channel 19 in the storage chamber 20 of the body 1.
  • the collecting channel 19 serves in a manner known per se for collecting condensation water, which precipitates on a rear wall evaporator 21 mounted in the rear wall 6 on the inside of the foam layer 15.
  • the inner wall 14 closes, via a shoulder 39 offset by a few millimeters to the rear of the device, in one piece, a further vertical wall 23 at. Diee bounded together with another wall 24, with which it is connected via a film hinge 25, a downwardly open groove 22.
  • a lower edge region of the back wall 9 is drawn around the lower edge of the wall 24, so that the lower cut edge of the back wall 9th is received in the groove 22.
  • the lowest point of the back wall carton is therefore formed by a bending edge 26, which is formed around the lower edge of the wall 24 around. Condensation that deposits on the outside of the back wall box 9 and flows downwards accumulates at the bending edge.
  • the shoulder 39 prevents the water from getting to the wall 14 and rising there between the upwardly unbent edge of the backwall carton 9 and the wall 14 or 22 and reaching the chipping edge of the carton 9. It can therefore drip only from the bending edge 26 down into the collecting channel 11. Since the bending edge 26 is continuously laminated on its outer side and the water can not rise up to the hidden in the groove 22 cutting edge, the back wall 9 is protected from moisture penetration.
  • a rib 27 extending below the gutter 11 and integrally connected thereto has the same wall thickness as the rear wall cardboard 9 and extends in the same plane as the edges of the rear wall cardboard 9 enclosed by the plates 7, 8.
  • the rib 27 is inserted in a groove 28 , which is formed at the rear edge of a bottom plate 29 of the body 1.
  • the bottom plate 29 may be the same as in a conventional refrigerator without the gutter 11 receives the lower edge of the back wall carton.
  • the base unit 3 has on its rear side a collecting projection 30, which is arranged below the drain opening 12 of the channel 11. Condensation, which drips onto the collecting projection 30, is derived from there into an evaporation tray 31, which forms part of the bottom of the base unit 3.
  • refrigerant lines 33 of the condenser may be partially immersed in the water 32 dipping.
  • Fig. 3 to 5 illustrate the assembly of the back wall 9 with a one-piece molding 34, which forms the collecting channel 11 and the groove 22.
  • the molding 34 is placed on a lower edge strip 35 of the back wall carton 9.
  • the wall 24 abuts against the edge strip 35, and a portion of the edge strip 35, which is approximately as wide as the wall 24, projects downward beyond it.
  • cutouts 40 are punched into the projecting portion of the lower edge strip 35 which, when the portion of the edge strip 35 projecting beyond the wall 24, is bent around the lower edge of the wall 24, as in FIG Fig. 4 shown, the latch hooks 36 record.
  • the cut of the Fig. 4 extends through one of the latching hooks 36, and one recognizes complementary to the latching hooks 36, a latching opening 37 in the wall 23.
  • the latching opening 37 meets the latching hook 36, as in Fig. 5 to see.
  • the in Fig. 2 is shown, all latching hooks 36 on a shoulder 38 (see Fig. 5 ) hooked their associated detent openings 37, so that the film hinge 25 can not open again.
  • the back wall board 9 and the molding 34 are positively fixed to each other, and the thus obtained unit of back wall board 9 and molding 34 can be mounted in the back wall 6 in exactly the same manner as conventionally the back wall board alone.
