Definitions

  • the invention relates to an electrical cooling device, in particular a refrigerator, with a cooling space which can be closed by a heat-insulating door and in which a temperature sensor is arranged, which is connected to a regulating device for regulating the cooling temperature which can be set by means of a temperature-setting device.
  • a refrigerator is known, on the back of which an evaporator connected to a compressor is arranged.
  • a capillary tube sensor is attached to the rear wall of the cooling chamber as a temperature sensor.
  • the temperature sensor is arranged at an optimal measuring point on the inner rear wall of the cooling room and is connected to the electronic controller by means of an electrical cable.
  • the electronic controller is housed on an inner side wall in a controller housing, which at the same time has a manually operated setting wheel for setting the desired cooling temperature.
  • a setting wheel is known for example from DE 94 20 648 U1.
  • Both the temperature sensor and the electronic control device must be housed in special housings that are waterproof and voltage-proof at the same time.
  • the electronic control device is also encapsulated in a watertight manner and immersed in protective lacquer.
  • the invention has for its object to provide a cooling device which ensures reliable temperature control with a simple and inexpensive structure.
  • the cooling device according to the invention should also be distinguished by simple and convenient operation.
  • the temperature sensor and the control device are arranged separately from the temperature specification device.
  • the temperature sensor and the regulating device are arranged inside and the temperature setting device is preferably arranged outside the cold room.
  • the cooling temperature can thus be conveniently set from outside the cooling device.
  • the refrigerator door does not have to be opened to adjust or check the set cooling temperature.
  • the housing can be encapsulated in a watertight manner and / or provided with a protective lacquer.
  • the temperature sensor and the control device are very advantageous to integrate on a common electrical circuit board. Housing the temperature sensor and control in an integrated circuit is particularly small. Such an arrangement can be easily introduced and sealed in a common housing.
  • the temperature setting device can have a potentiometer with a manually operable setting wheel, on which the desired cooling temperature can be easily set.
  • the single figure shows a cooling device in a side view and in the principle section indicated.
  • the cooling device has an inner cooling space 12 which is closed on one side by a cooling space door 10.
  • the refrigerator shown is a household refrigerator.
  • a flat evaporator 30 is arranged on the rear side of the cooling device and is connected to a compressor 28 via a pipe system.
  • the compressor 28 is connected via an electrical line to a housing 20 arranged inside the cooling space 12.
  • the housing 20 contains an electrical circuit board 20 on which an electrical temperature sensor 14 and the temperature control circuit 18 are accommodated.
  • the arrangement consisting of temperature sensor 14 and temperature control circuit 18 can also be arranged on an integrated circuit.
  • Such an IC chip can be produced inexpensively, in particular in the case of larger quantities, and is particularly small in size, so that the surrounding housing can also be made particularly small.
  • the housing 20 is watertight and at the same time cast in a stress-resistant manner.
  • a synthetic resin or similar plastic is used for this.
  • the temperature control circuit 18 is connected by means of an electrical supply line to a temperature setting device 16 which is attached outside the cooling space on the front side assigned to the door 10.
  • the temperature setting device 16 has a potentiometer 24, which is controlled by means of a Adjustment 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 using a scaling (not shown).
  • the temperature setting device 16 ′ can also be arranged inside the cooling space.
  • a step switch can also be provided, which enables the temperature preselection in predetermined temperature steps.
  • a scale can be provided on the tap changer, which represents the set temperature.

Abstract

L'invention concerne un appareil de refroidissement électrique comportant une enceinte frigorifique (12) fermée par une porte thermo-isolante (10). Dans cette enceinte est disposée une sonde thermique (14) reliée à un dispositif de régulation (18) qui régule la température de refroidissement et qui est réglable au moyen d'un dispositif de détermination thermique (16). La sonde thermique (14) et le dispositif de régulation (18) sont disposés séparément du dispositif de détermination thermique (16), à l'intérieur et de préférence à l'extérieur de l'enceinte frigorifique (12).
