- the evaporator is provided with a multilateral casing of a soft, elastic and / or deformable padding material.
- a direct freezing of the evaporator module and the evaporator environment, in particular thedeITAwandung prevented.
- it can lead to a freezing of the evaporator and the cushioning material on the one hand or the cushioning material and the device inner wall on the other.
- relative movements that occur due to thermal stresses can be compensated for by the deformable cushioning material, so that clicks caused by suddenly breaking connections are excluded.
- the padding material may in particular also have a thermal insulation function and accordingly act as a thermal insulator, which likewise has a positive effect on the energy consumption.
- the casing is provided at least on the plant sides of the evaporator, with which the evaporator comes to rest with walls of the cooling tank, in particular of the evaporator receiving space.
- the jacket is therefore provided where the evaporator could freeze.
- the sheathing only partially, for example in the form of a strip, on the abovementioned installation sides.
- the jacket of insulating material covers the contact surfaces of the evaporator over its entire surface.
- the cover of cushioning material cracking noises can be largely completely eliminated.
- care is taken here that no open abutting edges remain, but also the edge regions and edges of the evaporator housing are largely completely encased by the insulating material.
- the sheath covers two broad sides and three flat sides of the evaporator substantially completely.
- the sheath can basically consist of different materials. According to an advantageous embodiment of the invention, the sheath consists - A -
- the sheath is at least to some extent elastically deformable, so that it allows the described compensatory movements.
- the sheath may be at least partially hydrophobic, i. water repellent, be formed, wherein in particular at least the surface of the sheath is hydrophobic.
- the sheath does not absorb water during the entire operating time of the device. This can be achieved for example with a sheath made of a closed-cell foam material.
- the casing could basically be formed in one piece.
- the evaporator could be as it were foamed at its contact surfaces.
- the sheath consists of several pieces of foam, which are set accurately on the plant sides or surfaces of the evaporator and terminate flush with each other at their abutting edges, so that no open abutting edges of the evaporator remain.
- the cushioning material covering in the range of a few millimeters may already be sufficient.
- different wall thicknesses of the casing can be provided on different sides of the evaporator.
- the jacket can have a greater wall thickness on the side of the evaporator facing the cooling space than on the side of the evaporator facing away from the cooling space and / or on flat sides of the evaporator.
- the casing may have a thickness of 3 to 5 mm on the side facing the interior of the refrigerator, and a thickness of 1 to 3 mm on the remaining sides of the evaporator.
- a jacket with on all sides of the evaporator constant, sufficient wall thickness is used.
- the casing is connected to the surface of the respective evaporator surface, preferably non-positively and / or materially attached thereto.
- the sheath of foam can be glued to a metal jacket of the evaporator.
- the evaporator can be sufficiently secured in itself by accurately fitting in the designated evaporator receiving space.
- the evaporator receiving space is correspondingly adapted to the outer contour of the evaporator.
- the evaporator with a slight interference fit which is compensated by a slight elastic deformation of the sheath, is inserted into the evaporator receiving space.
- the slightly compressed foam of the jacket holds the evaporator wackeiok and shockproof in the evaporator receiving space.
- the evaporator with a non-positive fastening means are attached to the inner container. It proves to be advantageous if the evaporator is not attached by plastic plugs or bayonet, but by several screws at different points of the inner container at this. This further reduces the click sound.
- the evaporator receiving space can basically be designed differently. According to one embodiment of the invention, it may consist of a substantially trough-shaped depression in the container inner wall, which can be closed by an inner lid.
- the evaporator can be used from the interior of the cooling container forth in the evaporator receiving space in the inner container. If the inner lid is then placed on the trough-shaped depression in order to close it, the evaporator or the surrounding material applied to it comes to rest. Sheath made of upholstery material in contact with the tub bottom, the tub edges and the inner lid.
- the inner lid at least in the region of the evaporator, does not have any webs projecting into the evaporator receiving space, but is fastened lying flat on the edges of the trough-shaped depression.
- sealing beads of padding material in particular foam beads, may be provided at the edges of the inner cover and / or the edges of the trough-shaped depression, so that no cracking noises may occur between the inner cover and the container inner wall.
- FIG. 1 shows a schematic perspective overall view of a cooling device according to a preferred embodiment of the invention
- FIG. 2 shows a perspective inside view of the cooling container of the apparatus from FIG. 1 with the door open, showing the evaporator receiving space and the evaporator inserted therein in the rear wall of the cooling container, FIG.
- FIG. 3 shows a perspective view of the evaporator of the device from the preceding figures, which shows the jacket of insulating material on the metal jacket of the evaporator,
- FIG. 4 is a perspective view of an inner container lid for closing the evaporator accommodating space in the rear wall of the refrigerated container;
- Fig. 5 a schematic representation of the self-adjusting conditions in the case of the jacket provided with an evaporator and an ambient area
- Fig. 6 the self-adjusting conditions in an evaporator without sheathing and the surrounding area.
- the refrigerator 1 shown in the figures comprises a substantially cubic cooling container 2, which can be closed by a door 3.
- the interior space 4 of the cooling tank 2 shown in FIG. 2 is bounded by the walls of an inner tank 5.
- a trough-shaped depression 6 is formed which defines an evaporator receiving space 7, in which the evaporator 8 is accommodated.
- a blower 9 is also accommodated, which is arranged at the upper edge of the recess 6.
- the trough-shaped depression 6 is substantially rectangular, wherein the lower edge (cf., FIG. 2) is slightly sloping towards the middle.
- the trough-shaped depression 6 can be closed by an inner cover 20 shown in FIG. 4, which is adapted to the contour of the depression 6 with respect to its outer contour and is seated on the edge 11 which extends around the depression 6 and can be fastened there.
- On the lateral edges 11 right and left of the recess 6 of the inner lid 20 sits as airtight as possible, which can be achieved for example by the application of foam beads on said edges 11.
- the inner lid is not airtight on the edge 11 of the recess 6, so that air can be sucked in here.
- the blower 9 shown in Figure 2 sucks on this gap between the lower portion of the edge 11 of the recess 6 and the inner cover 20 air so that it flows upwards over the evaporator 8 and at the provided at the upper end of the inner cover 20 blower opening again flows.
- the evaporator 8 sits snugly in the trough-shaped depression 6. Its two vertical flat sides and its lower flat side sit fit exactly to the side walls of the trough-shaped recess 6 and are in contact with these. Towards the top, the evaporator receptacle 7 is larger than the evaporator formed so that free space remains, which receives the supply and discharge lines of the evaporator and other wiring.
- the evaporator 8 corresponds in thickness to approximately the depth of the trough-shaped recess 6, which would be measured perpendicular to the plane in Figure 2. If the inner lid is placed over the trough-shaped depression 6 in the inner container 5 in order to close it, a system of the evaporator 8 sets on the one hand on the bottom of the recess 6 and on the other on the inner lid. Although the evaporator 8 per se is accurately accommodated in the evaporator receiving space 7 and would be sufficiently secured in itself, the evaporator by a screw, preferably at the bottom of the trough-shaped recess 6, be screwed. This prevents in particular a Nachsteckrisonen the evaporator in the casing or wiring receiving cavity, z. B. during assembly.
- the evaporator 8 is encased in a sheath 12 made of closed-cell hydrophobic foam.
- the sheath 12 covers each of the entire surface of the contact surfaces of the evaporator housing 8, with which the evaporator 8 is present on the walls of the trough-shaped recess 6 and the inner lid.
- the evaporator 8 itself has an aluminum sheet metal jacket, which forms the abovementioned contact surfaces and, as it were, forms a housing of the evaporator 8. On this aluminum sheet metal jacket 12 foam is glued surface, so that the evaporator 8 is coated on all sides of said contact surfaces.
- the freezing condition shown in FIG. 5 results if renewed cooling takes place after a defrosting process.
- an ice layer between the sheath 12 and the evaporator 8 and the sheath 12 and the recess 6 is shown in each case. If there are thermal relative movements between the evaporator 8 and the inner wall of the device, they would lead to chipping the frozen ice drops without the sheath 12. However, the sheath 12 can compensate for these relative movements and therefore avoid corresponding cracking noises.
- Figure 6 shows the immediate freezing of an evaporator 8 without sheath directly on the inner surface of the recess 6, as they would set in the prior art without the sheath 12 according to the invention. If relative movements occur here, they can not be compensated for and the unwanted crackling noises occur.
