Abstract

The present invention relates to a cooling device (1) comprising at least one fresh food compartment (2) wherein foodstuffs to be cooled are placed, a compressor (3) that compresses and circulates the refrigerant fluid in the refrigeration cycle, at least one evaporator (4) that provides the cooling of the interior volume of the fresh food compartment (2) by absorbing the thermal energy, a fresh food compartment temperature sensor (5) that measures the temperature in the fresh food compartment (2), an evaporator temperature sensor (6) that measures the temperature on the evaporator (4), a first heater (7) disposed on the evaporator (4), a second heater (8) disposed at the rear side of the fresh food compartment (2) so as to heat the fresh food compartment (2) and a control unit (9) that regulates the operation thereof, and wherein the foodstuffs placed in the fresh food compartment (2) are prevented from freezing.

Description

technical field [0001] The present invention relates to a cooling device for preventing freezing of food placed in a fresh food compartment. Background technique [0002] In cooling devices, especially refrigerators, foods like vegetables, fruits and beverages are usually placed in fresh food compartments and are not expected to freeze. In the case of low ambient temperature, for example, below 0°C, even if the compressor providing cooling for the fresh food compartment does not work, the temperature of the fresh food compartment enclosure will drop close to a negative value and cause the food therein to freeze. In order to solve this problem, heaters which are usually arranged on the rear side of the fresh food compartment are used. However, at very low ambient temperatures (for example, at -15°C), even raising the area around the heater to the desired temperature value does not provide uniform heat distribution within the fresh food compartment and in some places suffers ...
