Definitions

  • the invention relates to an electric cooling device, in particular a refrigerator, with a closable by a heat-insulating door cooling chamber in which a temperature sensor is arranged, which is connected to a means of a temperature setting device adjustable control device for controlling the cooling temperature.
  • a refrigerator is known, on whose rear side an evaporator connected to a compressor is arranged.
  • a capillary tube sensor is attached to the rear cooling room wall in the cold room.
  • a cooling device according to the preamble of claim 1 is known.
  • the temperature sensor is arranged at an optimal measuring point on the inner rear wall of the cooling space and connected by means of an electric cable to the electronic controller.
  • the electronic controller is housed on an inner side wall in a controller housing, which at the same time has a manually operable thumbwheel for setting the desired cooling temperature.
  • a wheel is for example from the DE 94 20 648 U1 known.
  • Both the temperature sensor and the electronic control device must be housed in special housings that are waterproof and at the same time voltage-proof. In order to maintain a good quality control during operation, and the electronic control device is sealed waterproof and dipped in protective lacquer.
  • the invention has for its object to provide a refrigerator, which ensures reliable temperature control with a simple and inexpensive construction.
  • the cooling device according to the invention should also be characterized by a simple and comfortable operation.
  • the temperature sensor and the control device are arranged separately from the temperature-setting device.
  • the temperature sensor and the control device are arranged inside and the temperature setting device outside of the cold room.
  • the cooling temperature can thus be conveniently set from outside the refrigerator. To adjust or check the set cooling temperature, the refrigerator door does not need to be opened.
  • the temperature sensor and the control device is housed in a common housing.
  • the assembly is facilitated within the cold room, and at the same time components are saved.
  • the housing can be cast waterproof and / or provided with protective lacquer.
  • the temperature sensor and the control device is integrated on a common electrical circuit board.
  • Particularly compact is a housing of temperature sensor and control in an integrated circuit. Such an arrangement can be easily introduced into a common housing and seal.
  • the temperature-setting device may comprise a potentiometer with a manually operable Steilrad on which the desired cooling temperature can be easily adjusted.
  • the single FIGURE shows in side view and in the indicated principle section a cooling device.
  • the cooling device has an inner cooling space 12, which is closed on one side by a refrigerator door 10.
  • the illustrated refrigerator is a household refrigerator.
  • a planar evaporator 30 is arranged, which is connected via a pipe system with a compressor 28.
  • the compressor 28 is connected via an electrical line to a housing 20 disposed within the cooling chamber 12.
  • the housing 20 includes an electrical circuit board 20 on which an electrical temperature sensor 14 and the temperature control circuit 18 are housed.
  • the arrangement consisting of temperature sensor 14 and temperature control circuit 18 may also be arranged on an integrated circuit.
  • Such an IC chip can be produced inexpensively, in particular for larger quantities, and is particularly compact, so that the surrounding housing can also be designed to be particularly small.
  • the housing 20 is waterproof and at the same time potted stress-resistant.
  • a synthetic resin or the like plastic is used for this purpose.
  • the temperature control circuit 18 is connected by means of an electrical supply line with a outside of the cooling chamber on the door 10 associated front mounted temperature-setting device 16.
  • the temperature-setting device 16 has a potentiometer 24, which by means of a Adjusting wheel 26 can be adjusted manually.
  • the potentiometer 24 is connected to the temperature control circuit 18 in such a way that a predetermined temperature can be set by means of a scaling (not shown).
  • the temperature-setting device 16 ' may be arranged in an alternative embodiment, also within the cooling space.
  • potentiometer 24 may also be provided a tap changer, which allows the temperature selection in predetermined temperature steps.
  • a scale may be provided on the tap changer, which represents the set temperature.
