Definitions

  • the invention relates to a refrigerator according to the preamble of claim 1.
  • a condensation water outlet is provided below the evaporator.
  • this is a pipeline which is opened by defrosting by means of a flap and then closed again so that no hot air enters the evaporator.
  • the condensation drain provided below the evaporator comprises a catch basin in the form of a siphon, eliminating any closing elements such as flaps and their control.
  • the water-filled siphon ensures in a simple way that no air enters the evaporator, which would result in undesirable heating. This simplification is of particular importance in so-called no-frost refrigerators, in which the defrosting process is to be carried out periodically and as quickly as possible.
  • Fig. 1 shows a portion of a refrigerator 1 with a partially illustrated evaporator 10, which is arranged in an upright evaporator chamber 5 substantially.
  • the evaporator 10 forms part of a equipped with a compressor and a condenser cooling circuit, of which only the compressor 9 can be seen.
  • the evaporator 10 is used for cooling of at least one cooling compartment, which is carried out by means of a circulated via the evaporator 10 by means of a fan cooling air. This air is sucked from above into the evaporator chamber 5, flows through an outer part 5a of the evaporator chamber 5 down and then from below through the evaporator 10 therethrough upwards. How the cooling air in the refrigerator compartment (or in the cooling compartments) passes and is made there for circulation, is below with reference to a refrigerator embodiment after Fig. 2 and Fig. 3 described in more detail.
  • a condensation water outlet 50 is provided below the evaporator 10, which according to the invention comprises a collecting basin in the form of a siphon 51.
  • the siphon 51 forms part of a pipeline 52, which opens at the bottom 5b of the evaporator chamber 5 and at the exit into a Verdunsterschale 53 or directly into a sewer line.
  • the bottom 5b of the evaporator chamber 5 is funnel-shaped or has at least in the mouth region of the pipe 52 a funnel-shaped reservoir 54.
  • the filled with condensation siphon 51 ensures that after the end of the defrosting process no air through the pipe 52 into the evaporator chamber 5 and the evaporator 10, which would have an undesirable heating result.
  • the condensation water drain 50 is thus simply designed and there are no closing elements, such as flaps, etc., and no control to operate necessary.
  • the compressor 9 is arranged below the siphon, the heat contributes to the fact that the condensation in the siphon 51 does not freeze.
  • the simplification of the condensation water outlet according to the invention is particularly important in so-called no-frost refrigerators, in which the defrosting process is to be carried out periodically and as quickly as possible.
  • FIGS. 2 and 3 An embodiment of such a refrigerator 1 'is in FIGS. 2 and 3 indicated schematically and described below. Also, this refrigerator 1 'is provided with a arranged in an evaporator chamber evaporator, with the Fig. 1 corresponding reference numerals are designated.
  • the refrigerator 1 two superposed cooling compartments 2, 3, of which the lower serves as a freezer compartment 2.
  • the cooling compartments 2, 3 are each closable with a door 2a, 3a.
  • the evaporator 10 is arranged in a separate evaporator chamber 5 substantially upright on a rear wall 4 of the freezer compartment 2.
  • the air provided for the cooling is sucked from above into the evaporator chamber 5, flows through the outer part 5a of the evaporator chamber 5 down and then from below through the evaporator 10 therethrough.
  • a number of inlet openings 12 is present, via which the cooling air is introduced into the freezer compartment 2, wherein the by means of a fan, not shown in the freezer 2 circulating cooling air in turn passes through a number of provided in the lower part of the partition wall 11 outlet openings 13 from below into the evaporator 10.
  • the temperature in the freezer compartment 2 is measured and regulated so that the inlet openings 12 are closed when a setpoint value is reached, preferably with the aid of a slide 14.
  • connection openings 18, provided on the one hand, which lead to the upper cooling compartment 3, and on the other hand a number of return openings 17 for the circulating in the upper cooling compartment 3 cooling air available.
  • connection and return openings 16, 17 are preferably closed by means of a slider.
  • connection paths between the evaporator chamber 5 and the two cooling compartments 2, 3 are closed by means of slides 14, 16, so that no air circulation takes place in the freezer compartment 2, and also the air circulation in the upper cooling compartment 3 is suppressed.
  • the connection openings 18 to the upper cooling compartment 3 are connected to the return openings 17 and there is an air circulation in the evaporator chamber 5 alone, the air through the outer part 5a down, through the evaporator 10 through and up the connection 20 again flows from above into the outer part 5a. This ensures fast defrosting, in particular when the air in the evaporator chamber 5 is temporarily heated, for example by means of a heating coil (not shown in the drawing).
  • the thawing water is in turn in the way out of the Fig. 1 apparent and below the evaporator chamber 5 arranged condensation water outlet 50 collected (in FIGS. 2 and 3 not shown).
  • the assignment of the evaporator chamber 5 on the rear wall of the freezer compartment 2 is not absolutely necessary; it could also be positioned on a side wall of the same or even be assigned to one of the walls of the upper cooling compartment 3.
  • the solution shown allows a particularly advantageous air flow.
  • the means for closing and opening communication paths between the evaporator chamber 5 and the individual refrigerators may be different than slides, e.g. be designed as flaps or the like.
  • Fig. 4 shows in the context of the invention still a variant of a condensation water outlet 40, which in turn is arranged at the outlet of a funnel-shaped collecting basin 54 at the bottom 5b of an evaporator chamber.
  • the siphon 41 is formed by a tube part 42 and the condensation water collecting evaporator shell 43, wherein the tubular member 42 is advantageously arranged from the reservoir 54 approximately vertically immersed vertically downward into the evaporator shell 43 and so deeply protrudes into this, that its lower end 42nd 'always immersed in water.
  • the Verdunsterschale 43 is, as their name indicates, open at the top, so that the water contained in it can partially evaporate and does not overflow.
  • this water drain 40 is the same as the one after Fig. 1 because the Verdunsterschale 43 fills with the expiring condensation water and this pipe part 42 is always immersed in the water, which can be prevented that air can flow into the evaporator chamber.
