  • a freezer is known from DE-GM 77 03 184, the thermally insulated freezer floor with a floor thickness penetrating drain pipe is equipped. This is at its outlet end to a drainage bracket Drain line connected, which for the purpose of their Connection with a pipe section in the flowable Cross section of the drain pipe protrudes and which on the jacket the pipe section with sealing lips molded onto it which cooperate with the inner wall of the drain pipe, to create a seal between the two To generate line sections.
  • Supportive measures are at the front end of the drain side Section of the drain pipe arranged inner lips provided which on the pipe jacket of the drain pipe act on the facing pipe section.
  • the drain pipe in terms of its length essentially adapted to the thickness of the freezer base be, which increases the height of the drain pipe serving, below the freezer interior arranged space could be reduced, but hides one such formation of the junction between the two line sections the danger that at the junction Leakage water can leak, especially if either the Sealing lips on the pipe casing of the drain pipe or the inner lips not easily recognizable on the drain pipe Have a defect or the assembly of the two line sections not executed each other with the necessary care has been. Careful, the tightness at the connection point ensuring assembly means again a not insignificant increase in assembly time.
  • Another cooling device with a condensate drain is from the DE-GM 84 36 339 known, which consists essentially of a channel-shaped drain line, one for guiding the drain line serving, equipped with a pipe section counter-guidance and an essentially tubular drain connector is formed. This is on the pipe jacket of its outlet side End with several, one above the other and protruding from the thermal insulation of the cold room floor Holding ribs fitted, on which the on the opposite guide arranged pipe socket for connecting the drain pipe to the drain pipe around a continuous condensate drain to generate is postponed.
  • the object of the invention is to propose a condensate drain, which with a simple construction in terms of improved functional reliability and space-saving is constructed.
  • connection between the drain pipe and the drain pipe is generated by holding means arranged on the latter, which attack on the flow-through cross section of the drain pipe and which essentially within the walls of the Drain pipe are arranged.
  • the solution according to the invention provides a water supply for creates a condensate drain in which over the entire Length without additional, usually complex and easy to install significantly reducing sealing measures Leakage losses are always safely avoided. Allows at the same time the solution according to the invention minimizing the Overall height of the condensate drain in favor of enlarging the freezer compartment, because due to the type of connection according to the invention a connection section protruding clearly above the floor thickness the drain pipe is unnecessary.
  • the invention provides that the holding means the drain line as at its flowable cross section arranged resilient locking hooks are formed, which with their free hook ends designed as locking lugs and / or are non-positively connected to locking means.
  • Such a design of the holding means is next to a secure mounting of the drain pipe on the drain pipe an assembly to be carried out with a single movement achieved, the bracket generated possibly slightly is resolvable.
  • the locking hook provided with openings for the melt water are, the locking lugs with locking means designed as projections, which in the flow cross-section of the drain pipe protrude, rest together.
  • Such a solution is particularly characterized by the integration the holding means in the melt water guide.
  • the snap hooks are particularly simple and robust, if after a further advantageous embodiment of the object the invention provides that the locking hook from at least one divided into two wall segments Circular hollow cylinders are formed, the cylinder wall with at least one as a passage opening for the melt water is provided.
  • the invention provides that the drain pipe a circular cross-section has, in which the free ends of the locking hooks protrude and on which the projections are arranged along its circumference are on which the locking lugs of the locking hook, one Allowing pivoting movement for the drain line, pivotable are stored.
  • the invention provides that the drain line is designed as a channel, on the one forming the channel run Channel bottom the locking hooks are arranged and whose the Lateral channel walls limiting the width of their channel run in the area of through the sectors of the circular hollow cylinder formed snap hooks in the manner of a to the outlet of the channel brought together with an outlet opening provided circular ring and arranged concentrically around them.
  • a drain line equipped with these features is not only is it particularly easy to manufacture, it also shows in addition to a stable coupling option to the drain pipe a targeted water supply to the gutter outlet towards.
  • connection point designed as a swivel joint the drain pipe and the drain pipe are still unintentional induced, improper operation the drain line if after another advantageous Design of the subject of the invention is provided that the portion of the walls formed by the annulus opposite the remaining wall sections of the channel is carried out increased and the supernatant in one by outlet-side end of the drain pipe arranged concentrically Guide groove is guided.
  • the invention provides that the drain pipe on the outlet side around its cross-section through which it can flow has drained edge, which is inside the Walls of the drain pipe and the holding means Connection of the drain pipe and the drain pipe surrounds.
  • the partial sketch is simplified Contour of the lower section of a freezer 10 indicated, its heat-insulating resting on a base 11 Housing 12 together with an appliance door, not shown encloses a freezer compartment 13. This is for thermal insulation of the housing 12 by means of a non-cutting Shaping a plastic board produced inner container 14 demarcated and points to the surface of its bottom 15 a in the inner container 14 with incorporated slope on. At its bottom, this is the inlet side End of a serving as a process to a final profile 16th associated drain pipe 17 connected.
  • the drain pipe penetrates 17 the thickness of the thermal insulation of the freezer compartment floor 15 and is in one piece with, for example, plastic injection molding manufactured, the thermal insulation of the freezer floor 15 together with the bottom portion of the inner container 14 enclosing and the end receiving the door front End profile 16 connected.
  • the drain pipe 17 connected to the end profile 16 has on its outlet side opposite the freezer compartment 13 End, within its essentially circular trained, flowable cross section 18 projections 19, which over the entire circumference of the flow Cross section 18 are arranged, protrude into this and thus reduce its diameter.
  • Concentric around is the flow-through cross section 18 of the drain pipe 17 a cross-section at the end of its outlet end annular drip nose 20 arranged, the Diameter is larger than that of the cross-section through which flow can pass 18.
