Definitions

  • the present invention relates to a chest freezer comprising air circulation ducts that provide the air inside the freezing compartment to be directed to the evaporator.
  • the deep freezer also known as the chest type, comprises a single freezing compartment disposed inside a cabinet, the upper part of which is closed with a cover.
  • a compressor and a condenser are disposed in the machine compartment, at the lower part of the freezing cabinet, known as the cabinet base region, which is insulated from the freezing compartment and for example a fin-tube type evaporator is situated behind the evaporator cover situated in the freezing compartment. Cooling of the foods – beverages placed into the freezing compartment is realized by forced convection by means of a fan situated on the evaporator.
  • the air heated in the freezing compartment is sucked by the fan by means of the air suction ducts situated at the lower side of the compartment, passed over the evaporator and is sent back into the freezing compartment through the holes on the evaporator cover.
  • the grainy foods and liquids spilled into the freezing compartment can clog the air suction ducts situated at the base of the compartment.
  • the narrowing in cross sections of the air ducts causes the amount of air sucked from the compartment to decrease and hence decrease in the cooling performance and increase in energy consumption.
  • the food and beverage items spilled on the suction ducts at the base of the compartment cause generation of bad odors.
  • the chest freezer comprises a cabinet, a freezing compartment situated inside the cabinet, an evaporator that provides cooling and return air ducts that direct the air sucked from within the compartment to the evaporator.
  • the aim of the present invention is the realization of a chest freezer wherein the air circulation ducts situated inside the cabinet can be cleaned by the user.
  • the chest freezer realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a freezing compartment situated inside a cabinet wherein foods and beverages are placed and air circulation ducts that are disposed at the lower side of the freezing compartment and that provide the air inside the compartment to be delivered to the evaporator.
  • An opening is arranged on the cabinet wall, aligned with the air circulation duct and the air circulation ducts can be taken out of the cabinet through the opening and cleaned.
  • the air duct is fixed to a cover placed into the opening and recess-shaped handles are located on the cover. The user takes the air circulation ducts out of the cabinet by moving the cover in the horizontal direction by means of the handle.
  • the air circulation duct is produced in three pieces, two horizontal pieces and one vertical piece and the pieces can be taken out of the cabinet separately or all together.
  • the cover whereto the air circulation ducts are fixed, is configured as a hollow box and insulation material is placed into the cover.
  • insulation material is placed into the cover.
  • fixing extensions situated at the lateral sides of the air circulation ducts are embedded into the insulation material in the cover and the cover is provided to be firmly fixed to the air circulation ducts.
  • thermal insulation is provided in the opening – cover section of the freezing compartment by means of a flange that surrounds the cover and seated on the outer surface of the cabinet wall. Leak-proofing is improved by placing a gasket between the flange and the outer surface of the cabinet wall.
  • the food & beverage items spilled on the air circulation ducts situated on the base of the chest freezer are cleaned easily by the user taking the air circulation ducts out of the cabinet.
