Definitions

  • the present invention relates to a refrigeration appliance, in particular a domestic refrigeration appliance, with a storage space bounded by an inner container and a built-in component anchored to a wall of the inner container, in particular an evaporator.
  • the object of the invention is therefore to provide a refrigeration device with a plate-like mounting part, in particular an evaporator, in which the built-in part is clearly fixed and the occurrence of stresses between the mounting part and housing due to different thermal expansion behavior is avoided.
  • the object is achieved by play in a refrigerator with a limited storage space of an inner container and anchored to a wall of the inner container via at least two mounting points anchoring in the direction of a connecting line between two attachment points at the first attachment point play and at the second attachment point play.
  • the connecting line extends between the first and the second connection point, and the anchoring is free of play at the first attachment point also in a wall-parallel direction orthogonal to the connection line, i. the built-in part is displaceable at the first attachment point in any direction parallel to the wall of the inner container.
  • a third attachment point may be provided, which spans a triangle with the first and the second attachment point.
  • the attachment points should be as far apart as possible. Therefore, in the case of a substantially rectangular fitting, preferably the first and second anchoring points adjacent to the ends of a first edge of the fitting and the third anchoring point are centrally located on a second edge opposite the first edge.
  • the connecting line extends between the second and a third attachment point. Then, the anchoring should be playful at the first attachment point in a direction orthogonal to the bond line to prevent differential thermal expansion behavior of the wall and fixture from causing rotation of the fixture. At the third point of attachment, anchoring in the direction of the connecting line should be playful in order to prevent the occurrence of stresses.
  • the second and third anchoring points adjacent to the ends of a first edge of the rectangular fixture and the first anchoring point may be centrally located on a second edge opposite the first edge.
  • the attachment points can each be formed by stationary pins on the wall and holes penetrated by the pins of the insert. By the shape of the holes can be easily determined whether and, if so, in which direction and to what extent at a point of attachment game.
  • At least one of the holes may be formed in the near-wall plate and be covered by the wandfernen plate to conceal the anchorage.
  • At least one of the holes may be key-shaped, such that a head of a stationary pin can be pushed through the hole and the fitting can be engaged on the pin behind the head.
  • the keyhole shape is particularly useful for a hidden hole, as insertion of the pin is precluded by a hole of the fixture after its placement on the wall here.
  • the pins may be part of expanding rivets, each held in a cup tightened in the wall.
  • the use of the cup formed preferably as a blind hole formed in the inner container instead of a hole has the advantage that no opening is formed through which insulating material could enter the storage space.
  • the formation of the bowl can be simple and economical in one
  • the expansion rivet preferably has a tubular housing part with a shaft and an insertable into the bowl root portion and an insertable for spreading the root portion in the housing part plunger.
  • the plunger may conveniently be identical to the above-mentioned pin.
  • the root portion to be spreadable divided into separate and expandable wall segments.
  • At an end remote from the root portion of the shaft is preferably arranged on the fitting fitting elastic member to attenuate possibly excited by the operation of a compressor vibrations of the mounting part.

  • cups 8 are at different points of the walls of the inner container, in the case shown here on its rear wall 6 and the ceiling 7, tightened.
  • Each cup 8 receives a spreading rivet 9.

  • On the ceiling is secured by means of the expansion rivets 9, a flat shell 12 made of plastic.
  • a trough 13, which is arranged centrally at the rear edge of the shell 12, adjacent to the rear wall 6, receives a fan not visible in the figure. The fan is provided to draw cold air from the air gap 10 via a suction slot 14 between the bottom of the trough 13 and the rear wall 6 and to lead between the shell 12 and the ceiling 7 along the door 5.

  • the expansion rivet 9 is essentially composed of two parts, a tubular housing part 15 and a plunger 16.
  • the housing part 15 has a substantially hollow cylindrical root portion 17 in which two flexible tongues through slots 18 in two offset parallel to the longitudinal axis of the expansion rivet 9 parallel tongues 19 are cut free, and a shaft 20, stiffened by radially projecting struts 21, an annular flange 22 carries.
  • an elastically deformable O-ring 23 is inserted.
  • the plunger 16 has a flat head 24 and a protruding therefrom cylindrical, slightly widened at its tip 24 facing away from the head tip pin 25.
  • the widened tip 26 of the pin 25 is behind an inwardly directed circumferential rib 27 of the root portion 17 locked.
  • the free cross section of the root portion 17 is so large in front of the rib 27, so that the plunger 16 can freely penetrate into the passage of the housing part 15 to the rib 27, without deforming the root portion 17. Only when passing the rib 27 spreads the Pestle 16 whose tongues 19 apart. Behind the rib 27, the free cross-section of the root portion 17 is smaller than before, so that the tongues remain spread apart when the plunger 16 engages behind the rib 27.
  • a flat rib 28 running around outside on the root sections 17 presses into the walls of the cup 8 and produces a frictional connection, preferably even a positive connection between the root section 17 and the cup 8.
  • the length of the pin 25 is adapted to the thickness of the part of the plate evaporator to be fastened 1 1 or the shell 12, so that when the tip 26 is locked to the rib 27, the part 11 or 12 between the head 24 of the plunger and the elastically deformed ring 23 is clamped.

  • a third hole 32 is placed centrally near the bottom of the evaporator 11.
  • the diameter of the circular hole 30 corresponds substantially exactly to the outer diameter of a short annular nozzle 33 (see Fig.
  • the nozzle 33 thus provides a mounting position for the evaporator 11 exactly, if only the housing part 15 is inserted into its cup 8, but it is not yet locked by inserting the plunger 16 therein on the inner container 2.
  • the holes 31, 32 are elongated holes whose longitudinal direction substantially coincides with the direction of an imaginary connecting line between you and the hole 30. Due to the play between the oblong holes 31, 32 and the nozzle 33 of the engaging in them expansion rivets 9 manufacturing tolerances, in particular those that affect the placement of the holes 30, 31, 32 and the cups 8, can be compensated.
  • the inner container 2 and the evaporator 1 1 expand or contract to different degrees, this leads to a displacement of the expansion rivets 9 in the oblong holes 31, 32, whereby the formation of thermal stresses in the body 1 is avoided.
