Definitions

  • the present invention relates to a refrigerator with a condenser forced ventilation by a fan.
  • the storage space of such a refrigerator is cooled by means of a compressor, which is switched on and off in response to the temperature detected by a sensor mounted on the storage space.
  • the power of the compressor in the switched-on state is not regulated, a long-term control of the cooling capacity takes place via the ratio of the operating time of the compressor to the total operating time of the refrigeration device.
  • a refrigeration device according to the preamble of claim 1 is known, it discloses a refrigerator with compressor, a condenser and a fan for the forced ventilation of the condenser known in which a control circuit is arranged to detect the duty cycle of the compressor and a high speed of the fan to select if the relative duty cycle is above a limit and otherwise to select a low speed.
  • WO 2006/087690 A1 proposes to turn off the compressor and a fan cooling the condenser while the door of a refrigerator is open.
  • the object of the invention is to provide a refrigeration device with a condenser and a fan for the forced ventilation of the condenser, in which the noise is reduced by the fan at least temporarily.
  • the ambient temperature of the refrigerator can be used.
  • the actual temperature or the setpoint temperature of an interior of the refrigeration device can also be used.
  • refrigeration unit has a body 1 and a door 2, which enclose a thermally insulated interior 3.
  • the body 1 rests on a hollow, cuboidal base 4, which is divided by a parallel to the sectional plane of Fig. Partition in two rooms.
  • ventilation openings 5 are formed for the inlet and outlet of cooling air.
  • the cooling air first passes into the rear space of the base 4 in the perspective of FIG are hidden by the partition and therefore shown as dashed outlines, a condenser 6 and a compressor 7 are located.
  • a fan 8 In an opening of the partition wall, a fan 8 is mounted, which drives a flow of the cooling air from the rear to a front space of the base 4 through which the plane of the cut passes.
  • This front room contains an evaporation tray 9, which is fed into the interior 3 knockdown condensate.
  • a refrigerant circuit runs in a manner known per se from the compressor 7 via the condenser 6 to an evaporator 10 mounted in thermal contact with the interior 3 in the rear wall of the body 1 and from there back to the compressor 7.
  • a lighting assembly 11 is mounted in the interior 3.
  • the lighting assembly 11 includes a switch 12, which is actuated by a displaceable in contact with the door 2 plunger 13, and to detect the opening state of the door 2 and mounted behind a transparent screen 14 bulbs with the door open 2 and closed door 2 off.
  • the lighting assembly 11 further includes a temperature sensor 15 for detecting the temperature of the inner space 3 and a temperature controller 16, at which a user can set a target temperature of the inner space 3.
  • control circuit 17 which is housed in the example considered here in a cavity of a mounted on the body 1 countertop 18.
  • temperature sensor 19 is mounted for detecting the ambient temperature of the refrigerator adjacent to an outer surface of the countertop 18.
  • the control circuit 17 could be housed in any other suitable cavity of the device, in particular in the base 4, and the temperature sensor 19 could, for. B. in the rear space of the base 4 between the ventilation openings 5 and the condenser 6 may be arranged to detect the temperature of the incoming cooling air before it heats up the condenser 6.
  • the control circuit 17 is connected to the compressor 7 in order to switch it on and off in dependence on the actual temperature of the interior 3 detected at the temperature sensor 15 and the set temperature set on the temperature controller 16.
  • the control circuit 17 is further connected to the fan 8 to turn this time-correlated with the compressor 7 on and off.
  • the temporal correlation can be simultaneity in the simplest case; However, it is also conceivable to switch the blower 8 on and / or off with a specific delay with respect to the compressor 7, so that in an initial phase of the compressor operation in which no appreciable waste heat output at the condenser 6 is obtained, it is not forcibly cooled, and / or in a follow-up phase after switching off the compressor 7 residual heat, which is still stored in the condenser 6, discharged therefrom and thereby deprived of the refrigerant circuit.
  • the control circuit 17 regulates the speed of the fan 8, the higher the higher the temperature detected by the temperature sensor 19 is ambient.
  • a relatively noisy operation of the fan 8 remain reserved situations in which a high ambient temperature leads to a strong heat input into the interior 3 and, accordingly, also to a high dissipated by the condenser 6 waste heat.
  • a reduced speed of the blower 8 leads to reduced flow noise and to a reduced power consumption of the refrigeration device.
  • the speed control can be done solely on the basis of the detected ambient temperature; Alternatively, the target or actual temperature of the interior 3, in particular by forming the difference between this and the ambient temperature, be taken into account, since the heat flow into the interior 3 not from the ambient temperature alone, but from the temperature difference between the environment and the interior. 3 depends.
  • the control circuit 17 also evaluates the opening state of the door 2 via the switch 12 and, in the event that an opening of the door 2 has been observed between a current and the previous operating phase of the compressor 7, a higher Speed of the fan 8, as if such an opening of the door has not occurred.
