  • the evaporation rate of the evaporation tray is influenced by the ambient conditions. These are e.g. the ambient air temperature, air currents and temperatures in the vicinity or in thermal contact with the evaporation tray befind Anlagen components.
  • a common solution to compensate for sometimes low evaporation performance is to place a pipe in the evaporation tray.
  • This tube leads, for example, gas heated by the condenser to the evaporation tray. The additional heating results in a further evaporation effect of condensation from the evaporation tray.
  • a refrigeration device has a compressor and an evaporation tray for receiving condensed water.
  • the evaporation tray is arranged so that it encloses the compressor at least in sections.
  • the evaporation tray can comprise an at least partially curved surface, or an outer surface or contact surface, which can be applied flat on an at least partially curved surface of the compressor or lies flat against it.
  • the heat transfer between the compressor and the evaporation tray can be improved, resulting in a greater heating of the condensate in the evaporation tray and thus to an improved Evaporation performance of condensation in the evaporation tray leads. It can therefore be better utilized the waste heat of the compressor. Even with a less warming compressor so that a sufficient evaporation performance can be achieved. By enclosing the compressor through the evaporation sound, the evaporation sound can be arranged even with small spaces.
  • the evaporation tray can be pivoted into the space available, for example, above the compressor space. After pivoting in, we compress the compressor at least in sections through the curved, flat contact surface of the evaporation tray.
  • the contact surface of the evaporation tray is increased with the compressor, the heat transfer from the compressor is increased to the water in the evaporation tray.
  • the water in the evaporation tray thus heats up more than the water in conventional refrigerators. Due to the improved contact between the evaporation tray and the compressor, the evaporation performance can be increased accordingly.
  • the evaporation tray can be made small, thereby saving space and the evaporation tray can be reduced in weight.
  • the copper pipes provided on some refrigeration appliances, which serve to increase the evaporation capacity can be saved.
  • a refrigerant circuit of the refrigeration device comprises, for example, the compressor for compressing refrigerant vapor, a condenser downstream of the compressor for condensing the refrigerant vapor, and an evaporator downstream of the condenser and upstream of the compressor for vaporizing the liquefied refrigerant.
  • Compressor and evaporator are then preferably each provided with a heat exchanger for heat transfer between the supplied air and the fluid.
  • Under refrigeration device is in particular a household refrigeration appliance understood, ie a refrigerator, which is used for household management in households or in the catering sector, and in particular serves to food and / or drinks certain temperatures, such as a refrigerator, a freezer, a refrigerator combination, a freezer or a wine fridge.

  • the binding is realized in such a way that the compressor has a curved convex portion, which extends within a curved concave portion of the evaporation shell.
  • a curved convex portion which extends within a curved concave portion of the evaporation shell.
  • the convex portion and the concave portion may be at least partially spherical in shape.
  • the evaporation tray then sits like a hood, especially from above, on the compressor. This ensures optimal proximity of the evaporation tray and compressor and optimizes heat transfer. Furthermore, the evaporation tray is thereby centered on the compressor and prevents it from slipping off the compressor.
  • the evaporation tray can be latched to the compressor.
  • the evaporation tray can then be placed back on the compressor after emptying and attached thereto. Furthermore, a removal of the evaporation tray is facilitated for their cleaning.
  • releasably securing the evaporation tray to the compressor provides security against tilting and leaking of the evaporation tray compared to a simply loosely mounted evaporation tray.
  • the evaporation tray can be latched to the compressor by pivoting about the compressor. This makes it possible to guide the evaporation tray along a curvature along a curved surface of the compressor. As a result, latching can be achieved by moving the evaporation tray relative to the compressor even with curved mutually facing surfaces of the compressor and evaporation tray.

  • the depression runs, for example, in a slope, so that the bridge can easily initiate into the depression.
  • the locking element is formed substantially as a barb.
  • the collecting container is at least partially transparent.
  • the transparent collecting container allows easy readability of the liquid level in the collecting container by the user.
  • the collecting container can be produced, for example, inexpensively from plastic as an injection molded part.
  • the evaporation tray comprises an asymmetrical contact surface to the compressor.
  • the contact surface can be formed for example by an at least partially curved surface, in particular outer surface.
  • the asymmetrical contact surface may, for example, have differently curved contact sections with different radii of curvature.
  • the asymmetric contact surface may have a front curved contact portion and a rear curved contact portion.
  • Contact portion may be shallower curved than the rear curved contact portion, so have a smaller radius of curvature.
