Definitions

  • the present invention relates to a refrigeration device with an evaporator around which the air from a storage room flows and which is exposed to tires due to moisture condensing out of this air.
  • the DE 20 2014 009 192 U1 discloses a refrigeration device according to the preamble of claim 1 and shows a refrigeration device in which a projection is formed on a wall of an evaporator housing, which protrudes into a space between pipe bends of the evaporator.
  • the projection is covered with a silicone mat as a leveling layer.
  • the evaporator housing and the buffer can have a second projection and a second recess which engage in one another transversely to the longitudinal direction of the first projection. A detachment of the buffer from the evaporator housing is then only possible if the buffer is deformed at the same time.
  • the differently oriented projections can be distributed over a main wall and a side wall of the evaporator housing that is connected to the main wall over an edge. In this way, both projections can essentially protrude from the wall of the evaporator housing that supports them.
  • the passage is preferably surrounded by a sealing edge protruding into the evaporator chamber.
  • This sealing edge can engage in a recess in the buffer.
  • Fig. 1 shows a schematic section through a household refrigerator according to the present invention.
  • This is a combination device in which two storage chambers 1, 2 at different temperatures, typically a normal cooling compartment and a freezer compartment or a cold storage compartment, and a machine room niche 3 share a common housing 4.
  • One of the two storage chambers 1 is accommodated together with an evaporator chamber 5 in a common inner container 6.
  • the evaporator chamber 5 extends vertically and in the width direction of the housing 4 and covers most of a rear wall 7 of the inner container 6. It is delimited towards the front by a main wall of an evaporator housing 8.
  • a distribution chamber 9 which in turn is delimited from storage chamber 1 by a wall plate 10.
  • Two side walls 23 and a bottom wall 24 extend from the edges of the main wall 20.
  • the evaporator housing 8 of the refrigerator Fig. 2 can be identical to the one described above except for its installation position; ie the bottom wall 24 is located in the installed state on top and forms a ceiling of the evaporator chamber, the evaporator 11 is flowed through from top to bottom, and the opening 21 to which the fan 9 is attached is located below the evaporator 11.
  • the distance between the outer fins 26 of the evaporator 11 and the side walls 23 is considerably greater than the distance between the fins from one another.
  • the space between the outer fins 26 and the side walls 23 on both sides of the evaporator 11 must be closed by a bypass blocker.
  • Fig. 3 does not show the bypass blockers but projections 27, 28 on one of the side walls 23, which serve to anchor such a bypass blocker.
  • FIG. 4 FIG. 11 is an enlarged view of these protrusions 27, 28.
  • the rib 34 engages around an edge 47 of the buffer 35 opposite the flank 36 at one end.
  • the housing 4 When assembling the in Fig. 1 In the refrigeration device shown, the housing 4 is first assembled from the outer walls and the inner container 6, and the evaporator 11 is inserted into the inner container, connection lines of the evaporator 11 running through an initially still empty space between the outer walls and the inner container 6. The housing 4 is stabilized by foaming the gap and the connection lines are firmly embedded. The evaporator housing 8 is then mounted in the inner container 6. This assembly is made more difficult by the fact that the evaporator housing 8 blocks the view of the evaporator 11. According to the invention, the correct placement of the evaporator housing 8 is nevertheless possible with the aid of the buffers 35 previously attached to its two side walls 23.
