Definitions

  • the sensor tube bridging the spatial distance between the evaporator and the temperature controller either completely freely along the walls inside the device housing or at least in sections in a guide tube which runs in the heat-insulated walls of the device housing.
  • an electrically insulating protective tube which is made of flexible material in a hose-like manner in order not to hinder the laying of the sensor tube. It must be ensured here that the ends of the insulating protective tube cannot be moved in the axial direction, since otherwise there is a risk that locations on the sensor tube are unintentionally exposed, as a result of which the required safety against contact is no longer provided.
  • To the Secure fixing of the jacket are therefore clamps, clamps or the like. required, the attachment of which is difficult and costly.
  • the invention is therefore based on the object in cooling devices of the type described in more detail to determine the protective tube required for the electrical insulation of the sensor tube, so that the contact safety prescribed for the relevant electrical protection class of the device is ensured.
  • the protective tube is provided near its ends with an axial force-absorbing stop in the form of a deformation changing its outer diameter.
  • the ends can be securely fixed in a simple manner and secured against unintentional axial displacement, so that inadvertent exposure of the sensor tube is avoided.
  • the stop is designed as an annular bulge of the protective tube which is produced by compression.
  • the evaporator and the temperature regulator are provided with means for positively clamping the stops of the protective tube.
  • a household refrigerator designated 10 in FIG. 1 has a housing 12 which can be closed with a door 11, in the upper right corner region of which an evaporator 14 in the form of a box evaporator 13 is arranged behind an evaporator door 13.
  • the spatial distance between the temperature controller 18 and the evaporator 14 is bridged by a sensor tube 20 which bears against the inner wall of the housing 12 and is covered by a protective tube 21 over its free length.
  • the section of the sensor tube emerging directly behind the regulator / lamp housing 19 is inserted in a groove 22 arranged in the side wall of the housing 12, in which it is held securely by clamping points 23 arranged at intervals from one another.
  • the middle section of the sensor tube 20 is guided upwards in the throat between the side and rear walls of the housing 12 and is clamped there in a groove 25 formed between projecting guide strips 24 for the support gratings 15 and the rear wall of the housing 12.
  • the end section of the sensor tube 20 enveloped by the protective tube 21 is then guided in an arc from the rear wall of the housing 12 to the underside of the evaporator 14, which for this purpose is provided on the underside with a blind channel 27 for inserting its end. In this way, good heat transfer from the evaporator 14 to the end section of the sensor tube 20 is ensured.
  • the protective tube 21 enveloping the free length of the sensor tube 20, as can be seen in particular from FIG. 3, is provided near its ends with a stop 28 which absorbs axial forces and which is designed in the form of a deformation which changes the outer diameter of the protective tube.
  • these stops are designed as ring-shaped beads formed by compression of the protective tube, which on the one hand at corresponding points on the bottom of the evaporator 14 and on the other hand are positively clamped in the regulator-lamp housing 19. This can be done by clamping between two housing parts of the controller-lamp housing or by a corresponding deformation of the end of the blind channel 27 on the evaporator 14.
  • the protective tube 21 is connected to the free end of the sensor tube 21 assigned to the evaporator by clamping or the like. sealed watertight to prevent the ingress of moisture - such as condensation - and thus to ensure perfect electrical contact safety.
