Definitions
- the invention relates to a refrigeration device, in particular a household refrigeration device, e.g. a refrigerator, and a water outlet arrangement for a refrigeration device.
- a refrigeration device in particular a household refrigeration device, e.g. a refrigerator, and a water outlet arrangement for a refrigeration device.
- condensation water that has accumulated in a refrigerated goods container of the refrigeration device is passed through a water outlet arrangement into an evaporation container located in a machine room, in which it evaporates to the outside atmosphere.
- a water outlet component is attached to the inner container of the refrigerator. At the connection point between the two parts, it must be ensured that no capillary action can occur through which water could otherwise penetrate the insulating material. Otherwise the result would be a severe loss of the insulating effect and, under certain circumstances, the water drainage freezing.
- plastic parts in the machine room are made of a fire-proof material.
- Either metal or fireproof plastic can be used here.
- metal parts the freedom of design is limited, in the case of plastic parts made of fire-proof material, the choice of materials is reduced and expensive.
- the processing tools and recycling are complex.
- the present invention creates a refrigeration device according to claim 1 and a what water outlet arrangement for a refrigeration device according to claim 12.
- the idea on which the present invention is based is to provide a positioning device which positions the wall area and the tube device in relation to one another in such a way that the drip edge is radially fixed in the tube device at a circumferential distance from an inner wall of the tube device.
- the positioning device comprises a first surface contour area of the tube device and a second surface contour area of the wall area, which are arranged above the drip edge and connected to one another in a form-fitting manner. This makes it possible to spatially separate the drip edge and the positioning device, but still attach them close to one another on the refrigerated goods container and on the tube device.
- the positioning device comprises a first spacer device which has a plurality of ribs which, starting from the inner wall, are directed radially into the interior of the tube device and are arranged adjacent to an outer side of the wall area.
- the plurality of ribs of the first spacer device in the interior of the tube device extend axially up to the drip edge and are spaced apart from the wall area on their upper side. This further reduces the capillary effect.
- the positioning device comprises a second spacer device which has a plurality of ribs which, starting from the inner wall, are directed curved into the interior of the Röhrenein direction and are arranged adjacent to an outside of the wall area. This also creates elastic tolerance compensation against fluctuations in the thickness of the refrigerated goods container, which also acts as a self-centering function.
- the plurality of ribs of the second spacer device extend axially in the interior of the tube device as far as the drip edge and are at a distance from the wall area on their upper side. This further reduces the capillary effect.
- the tube device has a single tube. This minimizes the number of components required.
- the tube device has a first tube and a second tube, the first tube extending in a funnel shape up to an inwardly directed sloping edge of the first tube into the second tube and wherein the positioning device has the wall area and the first tube in relation to one another positioned so that the drip edge is circumferentially fixed at a distance from the inner wall of the first tube in the first tube.
- the first tube is made of non-fireproof plastic and the second tube is made of fireproof plastic or metal. This leads to a cost reduction.
- the second tube extends from the side of the machine room wall facing away from the insulating material area into the machine room. This further simplifies assembly.
- the tube device is glued or screwed to the wall area. This enables a stable connection to be achieved.
- Fig. 4 is a schematic cross-sectional view of a Wasserauslaufan order according to a fourth embodiment of the invention.
- FIG. 1a), b) show schematic cross-sectional representations of a refrigeration device and a water outlet arrangement provided therein according to a first embodiment of the invention.
- the refrigeration device 1 shown in FIG. 1a in particular a household refrigeration device, has a refrigerated goods container 2 which encloses a cooling space 3 for refrigerated goods.
- Condensate KW accumulated in refrigerated goods container 2 of refrigeration device 1 is passed through a water outlet arrangement W (shown only schematically in FIG. 1a) into an evaporation container S located in a machine room M above compressor K, in which the condensation water KW evaporates to the outside atmosphere .
- the water outlet arrangement W shown in detail in Fig. 1b) passes the condensate water KW from the refrigerated goods container 2 through a trough-shaped wall area 2a of the refrigerated goods container 2 directed towards the machine room wall 6, through an insulating material area 5 and through a machine room wall 6 into the evaporation container S, whereby through the design of the Wasserauslaufan order W ensures that no condensation KW penetrates into the insulating material area 5.
- the water outlet arrangement W has a trough-shaped wall area 2a of the refrigerated goods container 2 directed towards the machine room wall 6, which extends in a funnel-shaped manner to a drip edge 2b of the wall area 2a.
- a tube 10 which widens towards the wall area, is connected to the wall area 2a, for example by gluing.
- the drip edge 2b extends into this tube 10.
- the tube 10 extends over its length starting from the wall area 2a through the insulating material area 5 and through an opening 60 of the machine room wall 6 into the machine room M in order to direct the condensation water KW into the evaporation container S.
- the wall area 2a and the tube 10 are positioned relative to one another by means of a positioning device K1, K2 in such a way that the drip edge 2b is fixed in the tube 10 at a circumferential distance from an inner wall 10a of the tube 10.
- the positioning device K1, K2 comprises a first multi-curved surface contour region K1 of the tube 10 and a multi-curved second surface contour region K2 of the wall region 2a.
- the first and second several times curved surface contour area K1, K2 are arranged above the drip edge 2b and connected to one another in a form-fluid manner.
- the positioning device K1, K2 designed in this way ensures that the drip edge 2b cannot move due to the foam pressure of the insulating material area 5 and is centered in the tube 10. Furthermore, the centering around the circumference of the drip edge 2b with respect to the inner wall 10a ensures that the mentioned capillary effects are suppressed.
- the tube 10 additionally has a spacer device 11 which defines the distance between the machine room wall 6 and the wall area 2a.
- the drip edge 2b and the positioning device K1, K2 are spatially separated, but still close to one another, so that exact positioning is ensured during assembly.
- FIG. 2a) -d) show schematic representations of a water outlet arrangement according to a second embodiment of the invention, namely Fig. 2a), b) in cross-sectional view and Fig. 2c) in perspective view and Fig. 2d) in plan view.
