Definitions

  • the present invention relates to a refrigerator comprising a humidity and temperature controlled special compartment.
  • Refrigerators generally comprise special compartments wherein foodstuffs like fruits and vegetables are placed and wherein the control of humidity and temperature is performed independently.
  • the cold air entering into the compartment due to movable valves and the cavities between the compartment walls adversely affects the humidity levels of the foods inside the compartment and cause drying of the foods in the compartment.
  • a refrigerator comprising a plate having outlet openings that are opened controllably by means of the panel that moves by sliding, whereon the plate is disposed.
  • the aim of the present invention is the realization of a refrigerator wherein the refrigeration effectiveness of the humidity and temperature controlled special compartments is increased.
  • the refrigerator realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a body suitable for storing the foodstuffs and beverages to be cooled; a special compartment that is disposed inside the body and that is thermally insulated from the body; a wall that insulates the body from the outside environment; an evaporator that is disposed on the wall and that provides the refrigeration of the body; an evaporator lid disposed in front of the evaporator; more than one opening that is arranged on the evaporator lid and that enables the air cooled by means of the evaporator to flow towards the special compartment; a valve placed on the evaporator lid so as to be aligned with the openings; a frame wherein the valve is seated, supporting the valve and at least one slit that is arranged on the valve and that slides and displaces in front of the openings when the valve is moved.
  • the refrigerator of the present invention comprises an air directing rib that is disposed on the frame or the evaporator lid and that easily directs the air received from the evaporator to the channel surrounding the special compartment before filling into the special compartment.
  • the air directing rib By means of the air directing rib, the cold air is directed towards the fresh food compartment, particularly towards under the special compartment without air losses. Consequently, the refrigerator is enabled to operate more efficiently.
  • the refrigerator comprises a protrusion that is situated opposite the air directing rib extending from the special compartment towards the evaporator lid to form a neck together with the air directing rib.
  • the refrigerator comprises a damping element disposed on the air directing rib or the protrusion.
  • the damping element such as a gasket produced from a flexible material, decreases friction, thus preventing generation of noise.
  • the air directing rib is mounted by a pivoted connection on the evaporator lid or the frame and activated by an actuation means such as motor and opened when desired, allowing entrance of air into the special compartment.

  • the refrigerator (1) comprises a body (2) wherein the foodstuffs and beverages to be cooled are placed; a fresh food compartment (15) and a humidity and temperature controlled special compartment (3), both disposed inside the body (2); a channel (14) that performs heat exchange with the special compartment (3) by at least partially surrounding the special compartment (3); a wall (4) that insulates the interior of the body (2) from the outside environment; an evaporator (5) that is disposed on the wall (4) inside the body (2) and that provides the refrigeration of the interior volume of the body (2); an evaporator lid (6) that is disposed in front of the evaporator (5) between the evaporator (5) and the special compartment (3) and that enables the air cooled by the evaporator (5) to be directed into the channel (14), more than one opening (7) that is arranged on the evaporator lid (6) and that faces the special compartment (3); a valve (8) mounted on the evaporator lid (6) so as to cover the front of the openings (7); a frame (9) that is disposed
  • the valve (8) When the humidity and temperature controlled special compartment (3) suitable for placing foodstuffs like fruits and vegetables is desired to be cooled, the valve (8) is moved and the air cooled by means of the evaporator (5) is directed into the channel (14) through the openings (7) and through the slits (10) that partially or entirely open the front of the openings (7), allowing the passage of air in the desired amount. Furthermore, when required, the slits (10) are prevented from overlapping with the openings (7) by moving the valve (8) and the cold air flow is interrupted.
  • the refrigerator (1) of the present invention comprises an air directing rib (11) that is disposed on the frame (9) or the evaporator lid (6), that extends from the frame (9) or the evaporator lid (6) towards the side wall of the special compartment (3) and that at least partially covers the upper side of the channel (14).
  • the air directing rib (11) enables almost all the air passing into the channel (14) through the openings (7) and the slits (10) to circulate around the special compartment (3) and prevents the air circulating in the channel (14) from entering the special compartment (3) and other regions above the special compartment (3), for example the fresh food compartment (15).
  • the special compartment (3) is enabled to be cooled efficiently and the foods stored in the special compartment (3) are prevented from drying.
  • the refrigerator (1) comprises a protrusion (12) that is disposed above the upper side of the side wall of the special compartment (3) and that extends towards the evaporator lid (6) at the level of the air directing rib (11).
  • the protrusion (12) being situated opposite the air directing rib (11)
  • the cold air that passes through the valve (8) is prevented from entering the fresh food compartment (15) and the special compartment (3) and the cold air is directed towards the channel (14).
  • the length of the protrusion (12) is long enough such that a minimum distance is left between the protrusion (12) and the air directing rib (11) thereby preventing air from filling into the special compartment (3) and the fresh food compartment (15) and short enough to prevent generation of noise by contacting the air directing rib (11).
  • the refrigerator (1) comprises a damping element (13) disposed on the air directing rib (11) or the protrusion (12).
  • the flexible damping element (13) for example a rubber band, prevents the air directing rib (11) and the protrusion (12) from contacting each other, thus preventing the protrusion (12) and the air directing rib (11) from wearing off and generating noise.
  • the air directing rib (11) is mounted by a pivoted connection on the evaporator lid (6) or the frame (9) and activated by an actuation means such as a motor and opened when desired, allowing the air to enter the special compartment (3).
  • the cold air is directed towards the channel (14) and prevented from filling into the special compartment (3) and/or the fresh food compartment (15).
  • the refrigerator (1) is enabled to operate more efficiently and the foods inside the special compartment (3) are prevented from losing their moisture uncontrollably.
