Abstract
A chill blow-off port is provided on a front surface side within a refrigerating compartment, and a chill return port is provided on a back wall of the refrigerating compartment, so that a chill generated by a heat exchanger flows from the front surface side within the refrigerating compartment toward the rear in the depth. Thereby, temperature unevenness within the refrigerating compartment is effectively eliminated and a cooling rate of a preserved food is enhanced.
Claims34
A refrigerator comprising,
- partition walls,
- a main compartment vertically partitioned into a plurality of spaces by means of the partition walls, one of the spaces at an uppermost part forming a refrigerating compartment, the other spaces in lower parts forming other storing compartments including a vegetable compartment and a freezer compartment,
- doors formed at the respective refrigerating compartment and storing compartments,
- a duct formed in the main compartment, extending from a back surface side of said main compartment over a top surface side, and containing a blower and a heat exchanger therein,
- a chilled air blow-off port formed at one end of said duct on a top surface side and having an opening located only at an upper part of a front surface of said refrigerating compartment on a door side,
- a plurality of shelf plates vertically partitioning the refrigerating compartment into storage portions to have independent air flow paths, and
- a plurality of first chilled air return ports formed in a back wall of the refrigerating compartment in each of the storage portions except for an uppermost storage portion, communicating to said duct, and being arranged along a vertical direction, chilled air generated by said heat exchanger flowing from the front surface side facing said door within said refrigerating compartment through the independent air flow paths of the refrigerating compartment toward a rear side, and being returned to the duct through each of the first chilled air return ports even when the door of the refrigerating compartment is closed.
A refrigerator comprising,
- partition walls,
- a main compartment partitioned into a plurality of spaces by the partition walls, one of the spaces at an uppermost part forming a refrigerating compartment, and the other spaces in lower parts forming other storing compartments including vegetable compartments and a freezer compartment, said vegetable compartments having a low-temperature vegetable compartment and high-temperature vegetable compartment through a partition,
- a back surface duct and a top surface duct continuously formed from a back surface side of the main compartment over an upper surface side,
- a duct provided at one end of the top surface duct and having a chilled air blow-off port opened in an upper part of a front surface of said refrigerating compartment and a chilled air return port communicating with the back surface duct on a back wall of the refrigerating compartment, and
- a blower and a heat exchanger arranged in an upper part of the refrigerating compartment on a back surface side within the duct for supplying chilled air, said chilled air supplied from said blower being partially conducted through dedicated ducts into the respective vegetable compartments, the chilled air in each of said refrigerating compartment and said storing compartments being returned to a heat exchanger side through said back surface duct.
