Definitions

  • the invention relates to a refrigerator and / or freezer with an interior containing an evaporator and with a ventilated condenser arranged outside the interior.
  • Such a refrigerator is such.
  • B. become known from DE-OS 27 59 143.
  • the known type shows a household refrigerator with an air circulation and air cooling device for a first food storage chamber, which is kept at a temperature above freezing, and for a second food storage chamber, which is kept at a temperature below freezing point.
  • Air is circulated using a blower located adjacent the top of a vertical duct. This fan ensures that the air flowing through a cooling element is partly directed to one chamber and partly to the other chamber.
  • such cooling devices have a second fan motor, which is arranged outside the chambers and serves to ventilate a condenser arranged outside the chambers.
  • a disadvantage of such known designs is the arrangement of the blower in the interior of the cooling device because the heat incidence caused by the associated fan motor causes an increased energy consumption of the cooling device.
  • Another disadvantage when using two fan motors is the more complex control of the two motors and the additional wiring effort.
  • the invention has for its object to reduce the effort for ventilation of a cooling device mentioned.
  • the motor is fastened to the outside of a wall delimiting the interior, that an extended shaft end penetrates the wall and carries the fan wheel for the interior at its end and that the fan wheel for the condenser in the exterior on one short shaft end is attached to the opposite side of the motor.
  • This design enables a simple, space-saving arrangement and assembly of the fan motor with its two fan wheels or fan rollers.
  • the fan motor can either be attached to the rear wall, to the ceiling wall or to the bottom wall of the respective cooling room or freezer room.
  • the elongated shaft end penetrates the adjacent wall of the interior and carries the fan blade on the inside for the air circulation in the interior.
  • the passage of the extended shaft end to provide through the wall a plastic part provided with a bore, which is inserted into a recess in the cooling chamber wall and is provided on the outside with means for fastening the motor.
  • This design enables simple and safe mounting of the fan motor on the one hand and a reliable implementation of the extended shaft end through the wall on the other.
  • a reliable seal is preferably achieved in that the bore inside the plastic part is provided with two ring seals which are mounted in corresponding recesses.
  • the fan motor 11 has a shaft 12, the elongated shaft end 12a of which penetrates the wall 10, ends in the interior 13 of the cooling device and carries a first fan wheel 14.
  • a second fan wheel 15 is seated on a shaft end 12b which is led out on the other side of the motor.
  • the fan wheel 14 is used to circulate cold air 16 within the interior 13, and the fan wheel 15 is used to supply cooling air 17 to a condenser 18 arranged on the outer wall 10.
  • 19 denotes an evaporator mounted in the interior 13.
  • the shaft 12 is mounted in a plastic part 20 which is inserted into the wall 10 and contains two ring seals 20a.
  • the plastic part 20 has a flange-like widening 21 on the outside, which is provided with supports 22 for fastening the fan motor 11.
  • FIGS. 2 and 3 show two views of a cooling device 23, in which the fan motor 11 is attached to the outside of the rear wall of the cooling space 13 in the lower part.
  • An air duct 24 serves to guide the air 16 moved by the fan wheel 14 within the cooling space 13.
  • a compressor is designated by 25.
  • Axial fans, radial fans, cross-flow fans and combinations thereof can be used as embodiments of the fan.
