    DETAILED DESCRIPTION OF THE EMBODIMENTS

    [0032] Identical reference signs in the figures of the drawings refer to identical or functionally identical elements, parts or components provided that the opposite is not disclosed.

    [0033] FIGS. 1a), b) shows schematic cross-sectional illustrations of a refrigeration appliance and a water outlet arrangement that is provided therein in accordance with a first embodiment of the invention.

    [0034] The refrigeration appliance 1 that is illustrated in FIG. 1a), in particular a household refrigeration appliance, has a refrigerated goods container 2 that encompasses a refrigerating zone 3 for refrigerated goods.

    [0035] Condensation water KW that is collected in the refrigerated goods container 2 of the refrigeration appliance 1 is guided via a water outlet arrangement W (only illustrated schematically in FIG. 1a)) into an evaporation container S that is located in a machine compartment M above a compressor K, in which evaporation container the condensation water KW is evaporated to the outside atmosphere.

    [0036] The water outlet arrangement W that is illustrated in detail in FIG. 1b) guides the condensation water KW from the refrigerated goods container 2 through a tub-shaped wall region 2a of the refrigerated goods container 2, said wall region being oriented toward the machine compartment wall 6, through an insulating material region 5 and through a machine compartment wall 6 into the evaporation container S, wherein it is ensured by the embodiment of the water outlet arrangement W that no condensation water KW penetrates into the insulating material region 5.

    [0037] The water outlet arrangement W in accordance with the first embodiment has a tub-shaped wall region 2a, of the refrigerated goods container 2, oriented toward the machine compartment wall 6, said refrigerated goods container extending in a funnel-shaped manner as far as a drip edge 2b of the wall region 2a.

    [0038] A tube 10 which widens toward the wall region is connected to the wall region 2a by adhesive bonding, for example. The drip edge 2b extends into this tube 10.

    [0039] The tube 10 extends over its length starting from the wall region 2a through the insulating material region 5 and through an opening 60 of the machine compartment wall 6 into the machine compartment M in order to guide the condensation water KW into the evaporation container S.

    [0040] The wall region 2a and the tube 10 are positioned with respect to one another by means of a positioning facility K1, K2 in such a manner that the drip edge 2b is radially fixed in the tube 10 spaced circumferentially from an inner wall 10a of the tube 10. The positioning facility 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 multi-curved surface contour region K1, K2 are arranged above the drip edge 2b and are connected to one another in a form-locking manner.

    [0041] The positioning facility K1, K2 that is designed in this manner consequently ensures that the drip edge 2b cannot be displaced by the foam pressure of the insulating material region 5 and is centered in the tube 10. Furthermore, it is ensured by the circumferential centering of the drip edge 2b with respect to the inner wall 10a that the capillary actions mentioned are suppressed.

    [0042] In the region of the machine compartment wall, the tube 10 additionally has a spacing facility 11 which determines the distance of the machine compartment wall 6 to the wall region 2a.

    [0043] In the case of the first embodiment, the drip edge 2b and the positioning facility K1, K2 are therefore spatially separated, but nevertheless are provided close to one another so that during assembly an exact positioning is ensured.

    [0044] FIG. 2a)-d) illustrate schematic illustrations of a water outlet arrangement in accordance with a second embodiment of the invention, and namely FIGS. 2a), b) in a cross-sectional view and FIG. 2c) in a perspective view and FIG. 2d) in a plan view.

    [0045] The water outlet arrangement W′ in accordance with the second embodiment differs from the first embodiment in the design of the positioning facility A1, A2, A3 for the drip edge 2b.

    [0046] A tube 10′ which is connected to the wall region 2a and also the wall region 2a in the case of the second embodiment do not have repeatedly curved surface contour regions.

    [0047] On the contrary, a spacing facility is provided as a positioning facility A1, A2, A3 and said spacing facility has a plurality of ribs A1, A2, A3 that are oriented radially starting from the inner wall 10a′ of the tube 10′ into the interior of the tube and are arranged resting against an outer side A of the wall region 2a.

    [0048] The plurality of ribs A1, A2, A3 extend axially in the interior of the tube 10′ as far as the drip edge 2b however said plurality of ribs are arranged spaced on their upper side O from the wall region 2a. This supports the prevention of the capillary action and renders possible a more compact design than in the case of the first embodiment since it is not necessary to perform any modifications in the form of repeatedly curved surface contour regions on the wall region 2a of the refrigerated goods container 2.

    [0049] Apart from that, the second embodiment is constructed in a similar manner to the above-described first embodiment.

    [0050] FIG. 3a)-d) illustrate schematic illustrations of a water outlet arrangement in accordance with a third embodiment of the invention and namely FIGS. 3a), b) in a cross-sectional view and FIG. 3c) in a perspective view and FIG. 3d) in a plan view.

    [0051] The water outlet arrangement W″ in accordance with the third embodiment likewise comprises a positioning facility A1′-A6′ in the form of a spacing facility which comprises a plurality of ribs A1′-A6′ which are however oriented in a curved manner starting from the inner wall 10a″ into the interior of the tube 10″ and are arranged resting against the outer side A of the wall region 2a.

    [0052] In the case of this embodiment, the plurality of ribs A1′-A6′ also extend axially in the interior of the tube 10″ as far as the drip edge 2b and are spaced on their upper side O from the wall region 2a.

    [0053] Moreover, an elastic tolerance compensation against thickness fluctuations of the shaped refrigerated goods container 2 is provided by the curvature of the ribs A1′-A6′ and said elastic tolerance compensation simultaneously causes a self-centering effect.

    [0054] Apart from that, the third embodiment is constructed in a similar manner to the above-described second embodiment.

    [0055] FIG. 4 illustrates a schematic cross-sectional view of a water outlet arrangement in accordance with a fourth embodiment of the invention.

    [0056] The water outlet arrangement W″ in accordance with the fourth embodiment has a first tube 110a having a first inner wall 10a″ and a second tube 110b having a second inner wall 11a′″, wherein the first tube 110a extends in a funnel-shaped manner as far as an inwardly oriented inclined edge 3b of the first tube 110a to the second tube 110b.

    [0057] The positioning facility A1″, A2″ is likewise a spacing facility having a plurality of ribs A1″, A2″ as is already described in connection with the second embodiment. Unlike the second embodiment, in the case of the fourth embodiment the ribs A1″, A2″ are arranged with their upper side O resting against the wall region 2a.

    [0058] In the case of the fourth embodiment, with regard to the first and second tube 110a, 110b a material mix is realized, wherein the first tube 110a is produced from a non-fireproof plastic and the second tube 110b is produced from a fireproof plastic or metal.

    [0059] Special adhesive bonding processes/welding processes are not required in the assembly of the refrigerated goods container 2. The inclined edge 3b of the first tube 110a is used simultaneously as a lead-in chamfer into the second tube 110b, which facilitates the assembly of the second tube 110b which is carried out in the case of the present embodiment on the part of the machine compartment M.

    [0060] In the case of an accordingly selected insertion measure, the first tube 110a and the second tube 110b without further measures are sealed against the ingress of insulating material, for example insulating foam.

    [0061] It is preferred that the first tube 110a is initially mounted on the refrigerated goods container 2 and the entire housing including the machine compartment M can subsequently be mounted without special joining requirements/sequences.

    [0062] The second tube 110b can be mounted on the end and is fixed to the machine compartment wall 6 either using a bayonet fitting or by an adhesive bonding connection.

    [0063] Since only the second tube 110b is produced from fireproof plastic or metal, a smaller quantity of material of this type is required.

    [0064] The two-component design of the first and second tube 110a, 110b furthermore allows more design freedom for the remaining parts.

    [0065] Apart from that, the fourth embodiment is constructed in a similar manner to the above-described second embodiment.

    [0066] Although the present invention has been described above with the aid of preferred exemplary embodiments, said invention is not restricted thereto but can rather be modified in a variety of ways. In particular, the invention can be amended or modified in various ways without departing from the core of the invention.

    [0067] For example, a shape, a dimension or a geometry of the components can be modified in an arbitrary manner.
