Description

Refrigerating appliances with drainage

technical field

The invention relates to a refrigerating appliance, in particular a refrigerating appliance, having a drainage device for draining water produced there from an interior of the refrigerating appliance, in particular during defrosting.

Background technique

In conventional refrigerating appliances with a flat-bottomed inner container, the problem arises that the water generated during defrosting collects on the bottom of the inner chamber, and in order to prevent the water from flowing out over the entire width of the front edge and onto the floor, the inner chamber must The constant drying of this water on the bottom of the chamber makes the defrosting process unnecessarily labor-intensive.

In order to overcome this problem, a refrigeration appliance is proposed in DE 8906085U1, wherein a discharge duct is connected to the lowest point of the inner container, which extends to the outside through the intermediate chamber of the housing filled with insulating material and has A line section that can be pulled out from the body of the refrigerating appliance, so that when the end of the line section is pulled out, a collecting container can be connected, which collects the escaping defrost water.

The discharge duct of the conventional appliance comprises a vertical section extending through the insulation and a substantially horizontal section receiving the pull-out section and positioned outside the outer wall of the appliance housing. This arrangement requires the provision of an intermediate chamber between the outer wall of the bottom of the body and the base on which the refrigeration appliance is placed, the width of which is sufficient to accommodate said substantially horizontal section of the discharge duct. Since the height of the furniture compartments in which known refrigeration appliances are installed is usually already fixed, this intermediate space deprives usable interior space of the refrigeration appliance. In other words, an unfavorable ratio between the volume of the available interior space and the furniture compartment results.

Contents of the invention

The object of the present invention is to provide a refrigerating appliance with a drain line for draining water, which has a pull-out line section, wherein the drain line does not affect, or at least does not significantly affect, the positional requirements of the appliance and its internal The ratio between the available space of the room.

For this reason, the present invention proposes a kind of refrigerating appliance, and its main body that is provided with the doorway comprises inner container, outer wall and the intermediate chamber that is filled with insulating material between outer wall and inner container, and in this refrigerating appliance, the draining The discharge pipe extends from the lowest point of the bottom of the inner container through the intermediate chamber to the outside and has a pipe section that can be pulled out from the body, wherein the pipe section that can be pulled out is laid in the heat-insulating material and is opposite to the In a tube sealed with insulating material, wherein, at the lowest point of the bottom, a downwardly protruding drain plug is integrally formed on the inner container, and the tip of the drain plug projects into said tube, at A drain opening is arranged on the free end of the drain plug.

In one embodiment of the invention, the pull-out line section is laid in a pipe which is embedded in the heat insulating material and sealed against it. The line section is laid in such a way that it is superfluous to provide an intermediate chamber under the refrigeration appliance body. The sealing of the tubes prevents, on the one hand, the intrusion of water into the insulating material, which would affect its insulating capacity, and, on the other hand, prevents the intrusion of the foam into the tubes during foaming, if the insulating material is foam expanding in the intermediate chamber And block the pipe section that can be pulled out. The foam-surrounded tube is held securely in place by the condensed insulating foam.

If the inner container is configured with a surrounding eaves on the side of the doorway, as is known in conventional one-piece deep-drawn inner containers, then the pipes receiving the pull-out pipe sections are preferably connected to the eaves formed in the eaves. export. This allows the discharge duct to be completely assembled on the inner container before assembling the refrigerating appliance body, making the subsequent assembly of the body simpler than that of a refrigerating appliance without a discharge duct.

At the lowest point of the base, a downwardly protruding drain pin is preferably formed, from which a tip protrudes into the tube. On the one hand, such a drain plug can be easily formed by deep drawing during the production of the inner container, and on the other hand, the tip of the drain plug protruding into the tube can be used as a stop, which limits the drawable The degrees of freedom of motion of the outgoing pipe segment.

The pull-out pipe section is purposefully comprised of an inner section movable in the tube and a head section which cannot enter the tube so that it can be grasped by the user in order to remove the inner section Pull out from the tube.

In the inserted state of the pipe section, the end section is preferably received in a recess of the body, preferably in a recess of the surrounding eaves of the inner container. Since the end section does not protrude beyond the front side of the body, it is not required that the door of the refrigerating appliance is fitted with a pull-out duct section, whereby the same type of door can be used for the refrigerating appliance according to the invention as well as for a refrigerating appliance without a discharge duct traditional refrigeration appliances.

In order to make the pull-out line section easy to handle and on the other hand to obtain a largely closed, easy-to-clean housing surface of the refrigerating appliance, the end section is preferably dimensioned in such a way that, apart from two spaces for the operator's fingers The hollow portion is filled with the cross-section of the depression. For the same reason, it is preferred that the end section in the inserted state terminates flush with the outer surface of the body, in particular of the eaves, around the depression.

The end piece can have a removable cover in order to prevent unwanted moisture from escaping. Alternatively, however, the tip section is adjustable relative to the inner section between a first position in which it blocks the inner section and a second position in which it frees the passage from the inner section to the outlet .

In this case it is particularly expedient if the end piece fits into the recess of the body only in the first position.

Detailed ways

FIG. 1 shows an inner container 1 of a refrigeration appliance according to the invention in a perspective view. The open front side of the inner container 1 is surrounded by a circumferential web 2 protruding outwards from a side wall 3 , a top 4 and a bottom 5 . Drain channels 6 are pressed into the bottom 5, which meet at a lowest point near the front edge of the bottom 5. At this lowest point there is integrally formed a connection stub 7 which, as can be seen more clearly in section in FIG.

A recess 8 open to the front is embossed in the web 2 below the bottom 5 , and a hole 9 is cut in the bottom of this recess.

FIG. 2 shows a section through the bottom 5 and the adjoining webs in the depth direction of the inner container 1 , in a plane extending through the connection stub 7 and the recess 8 . One end of the tube 10 is locked tightly in the bore 9 by means of a bayonet connection, the end 11 of the tube facing away from the bore is closed. The connection stub 7 extends into the interior of the tube 10 through a side hole. The outlet at the free end of the connection stub 7 can optionally be machined into this connection stub directly after production of the inner container 1 or after assembly of the pipe 10 . Between the pipe 10 and the drainage groove 6, there is a seal 12 which surrounds the connecting short pipe 7 in the form of a collar and is force-lockedly fixed on the connecting short pipe 7. The connecting short pipe 7 starts from the drainage groove 6 Initially, the seal closes the lateral opening 13 of the pipe 10 like a jacket in an insulating foam manner. The connection stub 7 itself is blocked by a pull-out stopper 14 .

The displaceable line section 15 accommodated in the pipe 10 is shown in the sunken stop position. The inner section 16 of the pipe section 15, which is accommodated in the pipe 10 in this stop position, is formed by an open groove above or a pipe in which an elongated hole 17 is cut into the housing of the pipe 7 to which the short pipe 7 is connected. The tip reaches the elongated hole. The inner end wall 18 of the inner section 16 is dimensioned in such a way that it hits the tip of the connection stub 7 when the pipe section 15 is pulled out and thus defines an outer stop (not shown) of the pipe section 15 Location. Furthermore, the width of the elongated hole 17 is adapted to the outer diameter of the connection stub, so that the pipe section 15 is guided in a non-rotatable manner by the connection stub 7 over the extension length of the pipe section 15 .

The end section 19 of the movable pipe section 15, which is accommodated in the recess 8 in the position shown in FIG. Cover 20 constitutes.

In order to defrost a refrigerating appliance with the inner container 1 shown here, the pipe section 15 is pulled out, the cover 20 is removed, the collecting container (not shown) is placed under the mouth of the pipe section 15 and the plug 14 is removed, This allows water to flow out of the channel 6 via the line section 15 into the collecting container.

Figures 3A to 3C show the assembly steps of a discharge conduit according to a preferred configuration of the present invention. FIG. 3A shows the recess 8 of the web 2 and the connection stub 7 with the seal 12 plugged thereon viewed from the foam side of the inner container 1 in a viewing direction parallel to the completed assembly. The longitudinal axis of the tube 10 at the time. The bottom of the depression 8 is perpendicular to this viewing direction. The bore has the configuration of a circle which widens over two opposite circumferential sections.

The tube 10 has on its outer end a flange 21 complementary to the configuration of said hole 9, which can pass through it when the tube 10 is in the orientation shown in FIG. The hole 9 of the inner container 1 moves until the surrounding rib 22 of the tube 10 touches the foam side of the depression. Since the rib 22 covers the flange 21 in the perspective view of FIG. 3B, the latter is indicated in dashed lines in the drawing. The distance between the flange 21 and the rib 22 corresponds to the wall thickness on the bottom of the recess 8, so that the tube 10 can be turned about its longitudinal axis in the position of FIG. 3B and the bottom of the recess 8 is clamped on the flange 21 and rib 22 between. In the position of FIG. 3B the contact between the tip of the connecting stub 7 and the tube 10 prevents the latter from occupying a substantially horizontal position parallel to the viewing direction, whereby when the bottom of the recess 8 is clamped due to the rotation of the tube 10 When held between the flange 21 and the rib 22 of the tube 10, the tab 2 is under a bending stress which seeks to swing the tube 10 into a horizontal position parallel to the viewing direction. As soon as its bore 13 reaches in front of the tip of the connecting stub 7 due to the rotation of the tube 10 , the tube 10 swings upwards under the influence of this bending stress and presses against the seal 12 , while the connecting stub 7 engages in the tube 10 . In this way, the anchoring of the tube 10 to the recess 8 on the one hand and the sealing between this tube and the connecting stub 7 on the other hand are achieved with a small number of operations.

Figures 4A to 4C illustrate the use of the discharge duct according to the invention. As a rule, the pull-out line section 15 is completely sunk in the tube 10 and the recess 8 of the web 2 , the front side of the cover 20 is flush with the front side of the web 2 . The cutouts 23 at the mutually opposite edge regions of the cover 20 make it possible to grasp the cover 20 with two fingers and to pull it out together with the pull-out line section 15 into the position shown in FIG. 4B . In this position, too, an elongated hole 17 protrudes a little from the recess 8 , into which the connecting stub 7 engages. If the pipe section 15 can be pulled out to reach its outer stop defined by the contact between the end wall 18 and the connection stub 7 , the cover 20 is removed by further pulling, as can be seen in FIG. 4C . If the plug 14 is now also removed from the connection stub 7 , water can flow from the inner container via the line section 15 into the collecting container located below.

Figure 5A shows a modified discharge conduit configuration in a pulled-out state corresponding to Figure 4B. In the submerged state, the discharge duct according to this configuration is identical to that of FIG. 4A , so reference can be made to this figure. In this configuration, the end piece 19 is not constructed as a pull-off lid, but comprises a rigid plate 24, which can be made of the same material as the inner container 1 itself, on which a side-slit Sleeve 25 , which is shown in dotted lines in the figures because it is concealed behind plate 24 and inside duct section 15 .

The pipe section 15 is also provided with a slot 26 on its underside, whereby, by rotating the plate 24 by 90°, as shown in FIG. .

The plate 24 can be completely sunk into the recess 8 only in one position in which the slots of the sleeve 25 and the pipe section 15 do not overlap. If the plate 24 is located in front of the surface of the web 2, it prevents the door of the refrigeration appliance from closing. Therefore, the refrigeration appliance cannot be accidentally operated without the discharge line being blocked.

FIG. 6 shows a variation of the pull-out line section 15 of FIGS. 5A , 5B in a position corresponding to FIG. 5B . In this case, a sleeve 25 surrounds the inner section 16 , and water can flow out through overlapping bores 27 , 28 of the inner section 16 and the sleeve 25 . The socket 29 formed on the bore 28 of the sleeve 25 prevents water droplets from migrating laterally on the underside of the sleeve 25 and falling out of the collecting container.
