Definitions

• a collecting channel is formed in refrigerators with Coldwall evaporator conventionally on the cooled wall below the evaporator, in which collects downflowing water, and of the lowest point of which is passed through a conduit through the wall of the device, through which the condensed water can flow to a arranged outside the storage chamber evaporation tank.
• the collecting channel In order to catch the dripping water, the collecting channel must be wider than the space between the evaporator and the adjacent wall. If the drip height is too large, a portion of the water from the collection channel injected again and moistened adjacent deposited refrigerated goods. The space between the lower edge of the evaporator and the gutter is not usable because of the dripping water there to accommodate refrigerated goods.
• a known approach to solving this problem is to mount on a wall of the storage chamber below the evaporator a condensate collecting tray placed close enough to the evaporator to prevent spattering and through which the condensate can be fed to a collecting channel without splashing ,
• a known such rail has a substantially V-shaped cross section, with one leg of the V is mounted on the wall of the device and the other leg so far obliquely upwardly protrudes from the wall, that drops of water that detach from a lower edge of the evaporator fall on it. Through openings at the lower apex of the collecting rail the collected water drains and flows along the wall or drips in the immediate vicinity of the wall in the collecting channel below.
• Object of the present invention is therefore to provide a refrigerator with an internal evaporator, which allows optimal utilization of space and eliminates the problem of splashing.
• the distance between wall and gutter can be made large enough to avoid affecting the air circulation in the space.
• Refrigeration appliance is here understood to mean a domestic refrigeration appliance, that is to say a refrigeration appliance that is used for household management, such as, for example, a refrigerator or a refrigerated freezer combination.
• the channel leads the water to a laterally adjacent wall in order to allow it to flow down therefrom.
• problems due to manufacturing tolerances of the inner container are easier to avoid when a first branched off from the gutter a gap between the collecting rail and Bridging the wall along which the collecting rail passes, in order to bring the condensation from the channel to this wall and drain it.
• the collecting rail is attached to the evaporator, in particular by a snap connection.
• other types of attachment are possible, such as screw, adhesive or formations.
• the collecting rail need not be considered in the manufacture of an inner container for the refrigeration device, and existing models of inner containers can be used cost-effectively for the refrigeration device according to the invention.
• the width of the gap should be at least half the size of the gap.
• the first web preferably unconnected touches the side wall.
• the water can seep in direct contact with the side wall between this and the end of the web, thereby ensuring that it instead of dripping , flows in contact with the wall downwards.
• the channel may expediently comprise two branches sloping down to the first bridge.
• a second and a third land may each extend between one of the branches and the wall to stabilize the position of the collection rail relative to the wall.
• a collecting channel known per se is expediently formed on a lower edge of the wall.
• FIG. 1 is a perspective view of a refrigerator according to a first
• FIG. 2 shows a section through the suspension of a collecting rail at a lower edge of an evaporator of the refrigerator.
• FIG. 5 is a perspective view of a refrigerator according to a second embodiment of the invention.
• FIG. 6 is a partial plan view of the collecting rail of the refrigerator of FIG .. 5
• the evaporator 5 fills the rear wall 4 only about halfway in an upper area thereof.
• a collecting channel 8 is formed familiar in the expert of Coldwall refrigerators forth, from the lowest point of a line is guided through the rear wall 4 to condensate water from the collecting channel 8 (not shown) in evaporation tray to supply a machine room filling the rear lower corner of the carcass.
• the collecting rail 6 is anchored to the evaporator 5 by means of two integrally formed arms 9.
• Fig. 2 shows a vertical section through the collecting rail 6, the lower portion of the evaporator 5 and an adjacent piece of the rear wall 4 in a plane passing through one of the arms 9 cutting plane.
• a detent opening 10 is cut adjacent to its lower edge.
• Two fingers 1 1 at the top of the arm 9 engage around the evaporator 5 at the front and back, wherein a locking lug 12 of the front finger 11 engages in the latching opening 10. Since the front finger 1 1 remains accessible after attachment of the collecting rail 6, it can easily be removed again if necessary, by the finger 11 is bent so far that the latch 12 disengages from the opening 10.
• the collecting rail 6 has a channel-like cross-section with a shot bottom, the lowest point of which lies vertically below the lower edge of the plate evaporator 5. In order to be able to reliably catch drops falling from the evaporator 5, the rail 6 must approach closer to the rear wall 4 than the evaporator 5 does. However, in order not to interfere with a free air circulation through a gap 13 between the rear wall 4 and the evaporator 5, the distance d of the collecting rail 6 from the rear wall 4 is not less than half the width D of the gap thirteenth
• FIG. 4 shows a plan view of a collecting rail 6 according to a slightly modified embodiment. It differs from that described with reference to FIGS. 1 to 3 by the presence of two additional webs 15, each extending between the branches 7 and the rear wall 4.
• the webs 15 may be shaped so that condensation from higher, outer regions of the branches 7 flows over them to the rear wall 4, but they can also serve only by their contact to stabilize the alignment of the collecting rail 6 parallel to the rear wall 4 with the rear wall 4 and to prevent the collecting rail 6 in contact with pushed against refrigerated goods in an inclined position, could drip in the condensate from the evaporator 5 to the rail 6.
