Definitions

  • the present invention relates to a cooler comprising a drawer whose temperature and humidity is controlled by means of a cover having shape memory material.
  • coolers cooler and freezer compartments are cooled by sending into said compartments the air cooled by being passed over an evaporator.
  • the air passed over an evaporator by means of a fan is sent into the compartments by being passed through air blowing ducts on an evaporator cover disposed on the rear wall of the compartment.
  • Flaps are used to send air into certain special compartments such as a 0°C compartment and the like, which can be adjusted for a discrete temperature.
  • Compartment interior temperature information is obtained by a sensor provided in such a compartment, and flaps can be opened or closed by means of a motor according to this obtained information. Said compartment can thus have desired temperatures and low temperature swing values.
  • the flaps, motor, and the sensor used in such compartments and the electronic control unit through which these units are controlled have a complex control method and highly increase the costs.
  • shape memory materials can remember a shape they have at a given temperature. Such materials transform into martensitic phase in their normal state, and into austenitic phase upon reaching a given temperature.
  • a humidity control device comprising a shape memory material and a heater used for heating the shape memory material.
  • the shape memory material is positioned on an opening disposed on an air duct opening into a body.
  • the shape memory material isolates the humidity control device and the body.
  • the shape memory material is enabled to be opened and closed by being heated according to the humidity value set by a user, enabling adjusting the humidity.
  • the aim of the present invention is to realize a cooler comprising a drawer whose temperature and humidity is controlled by means of a cover having shape memory material.
  • the cooler realized to achieve the aim of the present invention and disclosed in the first claim and the dependent claims, comprises a cover made of shape memory material, disposed between an air duct provided on a rear wall and at least one storage chamber placed in a body, having two positions and closing upon heating and opening upon cooling.
  • the flow rate of the cool air blown through the air duct opening is enabled to be spontaneously controlled according to the temperature value of the storage chamber by means of the cover comprising shape memory material.
  • the pores of the shape memory material close.
  • the storage chamber is thus inhibited from being heated by being sent hot air.
  • the compressor is activated, the pores open due to contacting cool air, and the storage chamber is cooled by receiving cool air. This enables maintaining lower temperature swings in the storage chamber, enabling keeping the storage chamber at a desired temperature.
  • At least one opening is provided on the cover. This opening prevents complete blockage of the air flow towards the storage chamber.
  • the air flow is maintained at a low level when the compressor is not operating.
  • the air flow rate increases when the compressor is activated and cooling is thus continued.
  • the temperature swings of the storage chamber are kept at a low level when the compressor is not operating (halted period or defrosting, etc.) by sending less hot air into the storage chamber. Keeping temperature swings at lower levels prolongs the shelf-lives of the food products stored in the storage chamber.
