  • machine compartment 101a is disposed in the area behind the storage compartment in the uppermost part of heat insulating box 101 to accommodate compressor 109, i.e., in an area difficult for user's hand to reach and therefore regarded as a dead space.
  • This arrangement offers the following advantages. That is, the space in the lowermost part of heat insulating box 101, which is easily utilized by the user but has been occupied by the machine compartment of the conventional refrigerator, is effectively utilized as a storage compartment volume. Accordingly, the storage capability and usability can be greatly improved.

  • Upper delivery port 120 is provided in the vicinity of a lower surface of upper partitioning wall 118a which separates cold storage compartment 104 from second freezing compartment 105 and ice-making compartment 106. Cool air having flowed through flow duct 111c is supplied from upper delivery port 120 to second freezing compartment 105, ice-making compartment 106, and first freezing compartment 107. Cool air delivered from upper delivery port 120 circulates through second freezing compartment case 105b, ice-making compartment case 106b, upper freezing compartment case 107b, and lower freezing compartment case 107c.

  • Door 71 joined with door frame 135 is attached in a condition movable back and forth within second freezing compartment 105.
  • Door frame 135 is positioned on the bottom side of second freezing compartment case 105b so as to increase the food storage volume of second freezing compartment case 105b. Accordingly, the fixing unit between door frame 135 and inner plate 132 of door 71 is disposed in the lower part of second freezer door 105a.
  • the inner surface of second freezing compartment door 105a on the storage compartment side is constituted by inner plate 132.
  • projection 138 is formed on inner plate 132 so as to increase a creepage distance from second freezing compartment 105 to the outside of second freezing compartment 105 in the closed state of door 71.
  • Gasket 133 is provided throughout the circumference of the end of inner plate 132. Gasket 133 is brought into tight contact with outer box 102, and metal contact members 139 provided on upper partitioning wall 118a and lower partitioning wall 118b.
  • Frame protection member 140 is provided so as to cover a fixing surface of door frame 135 to inner plate 132.
  • Heat insulating material 141 is further provided between frame protection member 140 and the fixing surface of door frame 135 to inner plate 132.
  • cool air guiding portion 150 is formed at a lower end of frame protection member 140.
  • Engagement fixing portions 151 are further provided on frame protection member 140 for attachment of frame protection member 140 to door frame 135.
  • Screw fixing portion 152 is further formed in frame protection member 140 as a screw hole through which a screw is threaded to fix frame protection member 140 to inner plate 132.
  • projected area C of a profile of frame protection member 140 is larger than area A of fixing surface 135a of door frame 135 to inner plate 132, and than area B of contact surface 136a of frame fixing member 136 with inner plate 132.
  • protrusion dimension D of frame protection member 140 on the downstream side of flow of cool air in the vicinity of lower partitioning wall 118b is larger than protrusion dimension E of an upper end of frame protection member 140 on the upstream side of flow of cool air.
  • frame protection member 140 is designed such that identical frame protection members 140 are attachable to both second freezing compartment door 105a and ice-making compartment door 106a.
  • Cool air cooled by cooler 112 is forcibly delivered by blower 113 from upper delivery port 120 into second freezing compartment case 105b to cool stored foods.
  • cool air forcibly delivered by blower 113 is supplied to each of upper freezing compartment case 107b and lower freezing compartment case 107c within first freezing compartment 107.
  • Cool air having cooled the foods passes through a clearance between second freezing compartment 105 and upper partitioning wall 118a in an upper section, and passes through a clearance between second freezing compartment case 105b and upper freezing compartment case 107b in an intermediate section.
  • the cool air having flowed through the clearance in the upper section and the cool air having flowed through the clearance in the interruption are joined.
  • the cool air after being joined flows through a clearance below lower freezing compartment case 107c, and is sucked through returning inlet port 125 to return to cooler 112.
  • Cool air forcibly supplied by blower 113 from upper delivery port 120 into second freezing compartment case 105b passes through second freezing compartment case 105b, and flows toward second freezing compartment door 105a.
  • Frame protection member 140 is provided to cover the whole area of fixing surface 135a of door frame 135 so as to avoid direct contact between cool air having passed through second freezing compartment case 105b toward second freezing compartment door 105a, and the fixing surface between door frame 135 and inner plate 132. Cool air after collision with frame protection member 140 passes along a surface of frame protection member 140, and subsequently flows toward the cases within first freezing compartment 107.
  • Projected area C of the profile of frame protection member 140 is configured so as to meet conditions C > A and C > B as relationships with area A of fixing surface 135a of door frame 135 and with area B of contact surface 136a of frame fixing member 136 with inner plate 132. This configuration effectively prevents cooling of door frame 135 and frame protection member 140.
  • Projection 138 of inner plate 132 protrudes toward the storage compartment side to secure a sufficient creepage distance from metal contact members 139 in tight contact with gasket 133 of door 71, thereby preventing entrance of heat from metal contact members 139 also in contact with the outside air.
  • Frame protection member 140 has cool air guiding portion 150 on the tip side of projection 138 of inner plate 132, wherefore the creepage distance between metal contact members 139 and the space within second freezing compartment 105 further increases. In addition, the flow direction of circulating cool air is guided toward a direction away from metal contact members 139 to prevent entrance of heat.
  • Protrusion dimension D of frame protection member 140 in the vicinity of lower partitioning wall 118b and protrusion dimension E of the upper end of frame protection member 140 are configured so as to satisfy the relationship D > E.
  • This configuration allows the flow direction of cool air to be guided toward a direction away from metal contact members 139.
  • the direction of inclination thus produced becomes equivalent to the direction of inclination of draft of a metal mold of second freezing compartment case 105b, and therefore a flow path of cool air is easily secured between frame protection member 140 and second freezing compartment case 105b.
  • Heat insulating material 141 is provided between frame protection member 140 and fixing surface 135a of door frame 135 to inner plate 132. This configuration prevents indirect cooling of fixing surface 135a of door frame 135 resulting from cooling of frame protection member 140 by cool air. Accordingly, the power consumption further decreases.
  • the method for attaching frame protection member 140 to door frame 135 via engagement fixing portions 151 is a simplified attachment method, wherefore the number of production steps does not increase.
  • screw fixing portion 152 may be more rigidly fixed by screw fixation. In this case, since the screw hole of door frame 135 communicates with the screw hole of frame protection member 140, reduction of the number of parts can be achieved by utilizing screw 137 for fixing door frame 135.
  • screw fixing portion 152 may be eliminated.
  • Identical frame protection members 140 are adopted for both second freezing compartment door 105a and ice-making compartment door 106a. Accordingly, reduction of the metal mold cost, and reduction of overall cost are achievable.
  • the present invention includes a heat insulating box that includes an inner box, an outer box, and a heat insulating material that fills a space between the inner box and the outer box, and a plurality of storage compartments sectioned as upper and lower parts of the interior of the heat insulating box by a partitioning wall, each of the storage compartments having a different temperature zone.
  • the present invention includes doors disposed on individual front surfaces of the plurality of storage compartments, door gaskets provided on the doors and brought into tight contact with corresponding front surfaces around opening of the heat insulating box, and door frames that openably support the doors.
  • At least one of the doors includes an outer plate, an inner plate, a foamed insulator that fills a space between the outer plate and the inner plate, and a frame fixing member embedded in the foamed insulator.
  • Frame protection members are provided on storage compartment sides of the doors. This configuration prevents heat exchange caused by cooling of the door frames, thereby decreasing power consumption.
  • cool air guiding members may be provided on the storage compartment side of the doors. This configuration allows cool air circulating within the storage compartments to be guided toward a position away from the front surfaces around the opening of the heat insulating box which has a relatively higher temperature. Accordingly, this configuration prevents heat exchange between the circulating cool air and the front surfaces around the opening of the heat insulating box, thereby decreasing power consumption.
  • the frame protection members may be formed integrally with the cool air guiding members. This configuration eliminates junctions between components and allows cool air to flow smoothly, thereby reducing pressure losses, and decreasing power consumption accordingly. In addition, the cost decreases as a result of reduction of the number of parts.
  • a projected area of each profile of the frame protection members may be larger than at least one of an area of a fixing surface of the door frame to the inner plate, or an area of a contact surface of the frame fixing member with the inner plate.
  • a heat insulating material may be disposed between the frame protection member and the fixing surface of the door frame to the inner plate.
  • This configuration prevents direct contact between cool air and the door frame by the frame protection member and in addition, to increases heat insulation inside the frame protection member by the heat insulating material. Accordingly, this configuration prevents heat exchange between cool air and the door frame or the frame fixing member via the door frame, thereby decreasing power consumption.
  • the refrigerator according to the present invention is applicable to both household and business-use refrigerators.
