Definitions

  • the present invention relates to a refrigeration device, in particular a household refrigerator, with a condensation water evaporator.
  • a refrigeration device in particular a household refrigerator
  • a condensation water evaporator At the evaporators conventional refrigeration equipment is reflected in the operation of moisture.
  • the evaporator In a refrigerator, the evaporator generally does not continuously reach temperatures below 0 ° C, the condensate can flow continuously from the evaporator.
  • a layer of ice forming on the evaporator over time must be thawed from time to time.
  • a drain line from the evaporator to an evaporation tank, and the evaporation tank is mounted on a compressor to the waste heat generated by the compressor during operation, to evaporate in the container collected condensed water to use.
  • the amount of waste heat released by the compressor becomes smaller and smaller in proportion to the amount of condensate to be removed.
  • the problem may arise that the waste heat of the compressor is no longer sufficient to evaporate the accumulating condensate, and the evaporation tank overflows. If the overflowing water comes into contact with live parts of the refrigeration device, damage to the device can be the result, and also a risk to the user is not excluded. Also water damage to flooring, adjacent furniture, etc. are possible. It is therefore important to provide an adequate evaporation capacity for condensate even under unfavorable climatic conditions.
  • the object of the present invention is to provide a refrigeration device which is able to make available the heat released by a condenser for the purpose of evaporating condensate without impairing the heat output of the condenser.
  • the object is achieved by forming in a refrigerator with a cabinet-like housing, a arranged at the back of the housing condenser and at least one evaporation tank, the condenser first wall of a extending along the back of the housing duct and the evaporation container to the condenser on a second wall lie opposite the duct.
  • a plurality of evaporation containers is arranged vertically staggered.
  • both the radiated heat from the condenser and the air flow can be optimally utilized.
  • the evaporation containers can be designed to save costs on a one-piece molded plastic plate.
  • the second wall of the air duct is preferably formed by a rear wall of the housing itself, in other words, the condenser is mounted at a distance from the rear wall through the air duct.
  • the one-piece plate on which the evaporation containers are formed can then expediently serve as an outer skin of the wall, in particular in order to delimit an insulating foam layer of the rear wall.
  • an overflow through a locally deepest point in a side of the evaporation tank facing the air duct is formed on the at least one evaporation tank in order to supply over the overflow a respective next deep evaporation tank arranged on the wall or elsewhere.
  • the condenser is preferably constructed in a wire-tube technique, with a meandering tube through which the refrigerant to be liquefied flows, and with wires attached to the tube to stabilize it in shape.
  • the condenser comprises a plurality of horizontal pipe sections, wherein the vertical distance between two evaporation tanks corresponds to the distance between two of the pipe sections or a multiple of this distance.
  • one of the pipe sections or a plurality of pipe sections can be placed in a height matched to the position of the evaporation tank, so that heat radiation emitted by the pipe sections can be absorbed by the water of the evaporation tank.
  • a reflector surface may be formed over the evaporation tank.
  • the reflector surface may also help to limit the swirling of the air stream ascending in the air duct to the evaporation tanks and thereby accelerate the air flow in the shaft.
  • an evaporator of which the evaporating condensate comes, expediently high up in an interior of the housing, preferably attached to the ceiling of the interior.
  • a partition that divides the interior into an evaporator chamber and a storage chamber may serve to capture condensate draining from the evaporator.
  • Fig. 1 shows a schematic vertical section through a household refrigerator with a body 1 and a door 2, which define an interior 3.
  • the body 1 is assembled in a manner known per se from a deep-drawn plastic inner container 4, a plurality of plate-shaped outer skin elements and a layer 5 of a rigid foam, which fills the space between the inner container 4 and the outer wall panels.
  • a plastic injection molded rear wall plate 6 shown highlighted.
  • a plurality of grooves 7 are formed, which extend substantially horizontally, each with a slight slope towards the center, over the entire width of the rear wall 8 of the body 1. In the uppermost of these grooves 7 opens a guided through the insulating foam layer 5 of the rear wall 8 through drain line 9.
  • the drain line 9 is based on a partition 10, which divides the interior 3 in an evaporator chamber 11 and a storage chamber 12 and from a directly below the Ceiling of the carcass 1 mounted evaporator 13 dripping dew water dripping.
  • the refrigerator is a refrigerator and the temperature of the evaporator is on average above the freezing point, at least in non-operating phases of the evaporator 13, the condensate drip and pass through the line 9 to the outside.
  • the evaporator 13 is expediently still equipped with an electric heater, which makes it possible to heat the evaporator 13 from time to time in a non-operating phase above the freezing point, without simultaneously heat the storage chamber 12 significantly.
  • a continuous refrigerant tube comprises a plurality of horizontally oriented sections 16 connected together by semicircular arches.
  • the tube sections 16 are interconnected by a plurality of vertically oriented wires 17 soldered to two sides of the tube sections 16.
  • the distance of the pipe sections 16 of the condenser 15 corresponds to the distance of the grooves 7 in the rear wall panel.
  • Air which heats up in contact with the pipe sections 16 and the wires 17, rises in the air shaft 14 and thereby carries water vapor from the grooves 7 from. Since the inclined wall sections 18 each form a continuous transition without sharp edges between adjacent grooves 7, the air flow ascending in the shaft is substantially only directly adjacent to the condenser 15 Edges 19 of the grooves 7 swirled so that the water vapor is efficiently removed from the water surface; At other points, the air flow offers no appreciable resistance, so that even a low heating power of the condenser 15 is sufficient to set a strong air flow in the duct 14 in motion.
  • Fig. 3 shows an upper portion of the rear wall plate 6 in a perspective view. It can be seen here that the edges 19 of the grooves 7 from both a left boundary wall 20 as well as a mirror image of their opposite, not shown in the figure, right boundary wall down gently towards the center, so that the grooves 7 always in a middle Overflow section of their edges 19.
  • the edges 19 are additionally provided with a small centrally arranged notch 21, which also extends over the adjacent sloping wall portion 18 and overflowing water in the form of individual tropics 22 reliably and without losses in the next lower groove 7 passes.
  • the channels 7 are arranged exactly vertically one above the other, there is thus no risk that overflowing water outside the device falls to the ground.
  • evaporation tray 23 can, for example, like in Fig.
  • notch 25 may be formed in which the water, guided by capillary effect, obliquely downward and forward to a drip tip 26, under which the evaporation tray 23 protected inside the engine room without being able to protrude over the back panel 6 to the rear, can be placed.
