Definitions

  • the invention relates to a refrigeration device, in particular a household refrigerating appliance, according to the preamble of claim 1.
  • the refrigerant circuit of a refrigerator is known to have a condenser which may be attached to the outer rear wall of the device housing.
  • the condenser consists of a bent coil, on both sides of which a wire structure of longitudinal wires is welded.
  • the housing is double-walled with a cooling space bounding inner lining and an outer lining and an intermediate bathisolierschaum is formed.
  • the outer lining has two, in the device side direction opposite side walls made of sheet metal, the back of each device facing each other, inwardly bent edge flanges. Between the edge flanges of the two side walls, for example, made of plastic or cardboard rear wall may extend.
  • the welded on the condenser plate angle are in screw connection with the respective edge flanges of the sheet metal side walls. The screwing of the sheet metal angles on the two edge flanges of the side walls is connected in particular in the context of a large-scale production with high assembly costs.
  • the object of the invention is to provide a refrigeration device with a condenser attachment, wherein the condenser permanently and without great installation effort on the refrigeration device can be fastened.
  • this attachment should absorb the forces occurring during the transport test and in particular form no interference contour that can affect the assembly process.
  • the invention relates to a refrigerator with a heat-insulating wall, in which a heat insulation material is provided between an outer lining and an inner lining.
  • a heat insulation material is provided between an outer lining and an inner lining.
  • On the outer lining at least one connection profile is provided, on which the condenser can be mounted.
  • the connection profile for holding the condenser is formed in a backing part, which is arranged on the, the heat insulation material facing side of the outer lining.
  • the backing part is foam on the outer panel.
  • the backing part is thus embedded in a simple manner stationary in the thermal insulation material. In this way, the backing part can first be pre-positioned loosely on the outer lining in a pre-assembly step prior to foaming the heat-insulating material.
  • the refrigeration device according to the invention is used for household management and may be, for example, a refrigerator, a freezer, a freezer, a wine storage cabinet or a fridge freezer.
  • the outer lining may also have a mounting opening, via which the connecting profile formed in the backing part is accessible from the outside.
  • the outer lining carrying the condenser can be a sheet-metal wall in which the assembly opening is introduced before the foaming process is carried out with the aid of milling robots or punching tools.
  • the connection profile can protrude from the outer lining with a predetermined, slight excess through the mounting opening.
  • the connection profile may also be formed as a hollow profile, which is limited foam-tight by the backing part. In the formed as a hollow profile connection profile thus no space outside the outer lining is taken. In this way, no interference contour on the rear wall of the refrigerator is present in the assembly process of the refrigerator, which possibly complicates the transport of the device on the back of the conveyor during assembly.
  • the backing piece can be inserted into the mounting opening of the outer lining and pre-positioned therein before the foaming process.
  • the backing part can be pre-positioned in the assembly opening, for example, by a latching connection or a clamping connection.
  • the backing part additionally has a sealant that can foam-tight seal the mounting opening to the outside.
  • a circumferential elastically yielding sealing lip may be formed on the backing part, which in the installed position on the side facing the thermal insulation material is pressed against the edge region of the mounting opening of the outer lining in a foam-tight manner.
  • the backing part may in this case be designed as a housing that limits the connection hollow profile.
  • the housing may also have a guided through the mounting hole insertion slot through which a fastened to the condenser holding part can be inserted. In the insertion direction, the connection hollow profile can connect to the insertion shaft.
  • the outer lining is made by opposing side walls and by a bottom and a top wall and by a rear wall.
  • the side walls are known to be made of sheet metal thin wall thickness executed and have the back of the device inwardly folded edge flanges on. Between the edge flanges extends the rear wall, which is preferably made of plastic or cardboard.
  • the condenser is attached to the two inwardly folded edge flanges of the sheet metal side walls.
  • the backing parts formed with the connection profile can be arranged in each case on the two opposite, device-rear-side edge flanges of the sheet metal side walls.
  • the condenser may have on its upper side two sheet metal angles, which can be brought, for example, in latching connection with the refrigeration device.
  • hook elements can be provided which can be hooked into contour-matching connection profiles on the refrigeration device.
  • the condenser can be fastened by a simple latching and / or plugging operation on the back of the device. It is therefore advantageous if the connection profile of the backing part has at least one locking rib which can be brought into latching engagement with a corresponding sheet metal angle of the liquefier. Alternatively or additionally, the connection profile can also have an undercut into which a hook element of the condenser can be suspended.
  • the backing part can be located anywhere up or down on the outer panel, it is advantageous if the Schulegmaschine are designed as common parts, which can be used if necessary on Envelope at both opposite in the device side direction edge flanges of the outer lining.
  • each of the backing parts in a double function permits at least two different attachment options of the liquefier.
  • the backing part can have a connection profile in which both the locking rib for the latching connection with the condenser and the above-mentioned undercut for hooking in a condenser hook element are made possible.
  • a condenser 5 is supported at the back of the device housing 1 at the back of the device housing 1.
  • the condenser 5 is in the Fig. 1 for clarity, detached from the back of the device housing 1 shown.
  • the condenser 5 is designed by a running in a vertical plane coil, which has in the depth direction y on both sides of a welded wire structure 7, 9, each consisting of vertically extending wires.
  • the device housing 1 is double-walled with a, in the Fig. 1 shown outer lining 11, a plastic inner lining, not shown, and a foamed therebetween heat insulating layer 15 constructed.
  • the outer lining 11 is constructed by two, in the device side direction x opposite sheet metal side walls 17 and a bottom wall, a top wall 18 and a rear wall 21. According to the Fig. 1 have the two opposite side walls 17 on the back of each rearwardly bent edge flanges 19 on. These overlap the side edges of the rear wall 21, which is usually made of plastic or cardboard.
  • the condenser 5 For mounting on the back of the device housing 1, the condenser 5 has a total of four holding parts 23, 25. These are exemplary sheet metal angles, which are welded with a leg 27 to the wire structures 7, 9 of the condenser and are secured to the other leg 29 on the back of the device.
  • the fastening legs 29 of the upper holding parts 25 each have vertical elongated holes, while the fastening legs 29 of the two lower holding parts 23 are each designed as hooks.
  • the mounting legs 29 of the holding parts 23, 25 in access openings 31 of backing parts 33 insert as shown in the following Fig. 2 and 3 is shown. That in the Fig.
  • connection hollow profile 35 for holding the condenser 5.
  • the connection hollow profile 35 is accessible via the already mentioned access opening 31 to the outside.
  • the access opening 31 is in the Fig. 2 to 4 delimited by a slot-shaped insertion chute 37 of the backing part 33.
  • the insertion shaft 37 is again guided through a mounting opening 39 of the outer panel 11.
  • the mounting hole 39 is formed as a punching in each case in the inwardly folded edge flanges 19 of the two sheet-metal side walls 17.
  • the backing is shown with omitted side wall, so that the connection profile 35 is visible.
  • the connection profile 35 has according to the Fig. 2 to 4 a locking rib 41, which is integrally formed on the remaining side wall 43 of the backing part 33.
  • Each up and down the hollow profile 35 is extended with undercuts 45.
  • connection of an upper condenser holding part 25 to the backing part 33 is shown. Accordingly, the mounting leg 29 of the holding member 25 is inserted through the insertion shaft 37 through into the connecting hollow profile 35.
  • the slot formed in the mounting leg 29 is in latching connection with the locking rib 41. To accommodate mounting tolerances, the slot is dimensioned by a movement play s longer than the locking rib 41. In contrast remain in the Fig. 2 the undercuts 45 in the connection hollow profile 35 disengaged.
  • Fig. 3 In contrast to Fig. 2 is in the Fig. 3 the holder of a lower condenser holding part 23 is shown. Accordingly, now the hook formed on the attachment leg 29 is inserted into the connection hollow profile 35 and this engages behind the lower undercut 45. With the help of the hooks formed on the lower holding parts 23, the condenser 5 can at least partially be supported in the connection hollow profile 35.
  • the backing piece 33 is mounted on a side 47 of the edge flange 19 facing the heat insulating foam 15 even before the heat insulating foam 15 is foamed up.
