As shown in FIG. 3 of the cross-sectional view taken along the line BB of FIG. 1, the refrigerating chamber door 6a is rotatably supported around the support shaft S1 and is made of a pocket-shaped translucent resin molding for storing drinks and the like. The door storage 6a1 is projected to the inside, and a rotary partition 6a2 is provided on the back surface thereof so as to be swingable by the urging force of the torsion coil spring and the guide.

The rotary partition 6a2 prevents cold air from leaking from between the refrigerating chamber doors 6a and 6b at a position along the left refrigerating chamber door 6a when the refrigerating chamber doors 6a and 6b are closed (see FIG. 1). When the refrigerating chamber door 6a is opened, the refrigerating chamber door 6a is configured to rotate in the thickness direction (indicated by a two-point chain line) so as not to disturb the user.

Further, the refrigerating room door 6b on the right side is rotatably supported around the support shaft S2, and a pocket-shaped translucent resin-molded door storage 6b1 for storing drinks and the like is projected on the inner side. ..

The chilled chamber shown in FIG. 3 is maintained in a chilled temperature range (for example, a temperature range of about 0 to 2 ° C.).

As shown in FIG. 3, when the refrigerating chamber door 6b is closed, a predetermined space is formed between the door storage 6b1 of the refrigerating chamber door 6b and the chilled chamber lid 16 of the chilled chamber 13 so as not to come into contact with each other. It is configured. The chilled chamber 13 is formed in a box shape having a width equal to or narrower than the width of the refrigerator compartment door 6b, which is one of the double doors.

The chilled chamber 13 has a flat outer member (storage portion) 14 having openings on the upper surface and the front surface and a long substantially rectangular parallelepiped shape in the back, and a lid member that opens and closes in front and behind to take in and out internal storage. It has a chilled chamber lid 16 and the like.

The outer member 14 is resin-molded using ABS (resin containing acrylonitrile, butadiene, styrene), AS (resin containing acrylonitrile, styrene), etc., and the left and right side walls 14a and 14b, the bottom wall 14c, and the rear wall 14d (FIG. 3), and the upper surface having the front wall 14e and the front surface are formed in an open shape.

FIG. 5 is a conceptual diagram of the chilled chamber 13 shown in FIG. 4 in the C direction.

As shown in FIG. 5, the chilled chamber lid 16 has a substantially rectangular shape when viewed from the front, and has an elongated shape in the left-right direction. Further, the chilled chamber lid 16 is provided with an opening / closing handle 26. On the back surface of the chilled chamber lid 16, an elastic packing 16p is disposed on the inner peripheral edge portion that comes into contact with the outer shell member 14 when closed, and this packing 16p is between the outer shell member 14 and the chilled chamber lid 16. We are sealing.

Next, the mounting structure of the lighting device 46 such as the LED substrate will be described. FIG. 6A is a side sectional view provided with an opening above the rear wall of the outer member 14. FIG. 6 (b) is an enlarged view of the E portion of FIG. 6 (a). FIG. 7 is a perspective view of the translucent member 43. FIG. 8 is a perspective view of the cover member 45.

As shown in FIG. 6, the lighting device 46 having an LED, a substrate, and the like is fixed to a translucent member 43 separate from the outer member 14. Further, the cover member 45 that covers the lighting device 46 is fixed to the opening edge of the outer member 14 from the outside. Here, the translucent member 43 has an edge portion 43f extending in the wall surface direction of the outer shell member 14, and by sandwiching the edge portion 43 between the outer shell member 14 and the cover member 45, the outer shell member 14 is sandwiched. The translucent member 43 is fixed.

Further, as shown in FIG. 7, the translucent member 43 is provided with a cylindrical portion 43a that serves as a light guide plate. By inserting the seal member 42 into the cylindrical portion 43a, the airtightness at the opening of the outer member 14 is improved, and the inside of the chilled chamber 13 can be depressurized when a decompression pump (not shown) is driven.

The translucent member 43 is provided with the locking pieces 43b and 43c shown in FIG. 7. The locking pieces 43b and 43c project to the opposite side (outside) of the outer member 14, and the side cross section is an L-shaped portion. When the lighting device 46 is pushed onto the L-shaped portion from top to bottom, the end sides of the locking pieces 43b and 43c are pushed open. After that, when the illuminating device 46 comes to a predetermined position, a force elastically pressing the illuminating device 46 against the translucent member 43 side acts on the end side of the locking portions 43b and 43c, and the illuminating device 46 acts. Is fixed.
Further, as shown in FIG. 6, the lighting device 46 and the translucent member 43 provided with the sealing member 42 are fitted into the opening edge above the rear wall of the outer member 14 to maintain the sealing property. The sealing member 42 is made of a flexible material such as silicon.

As shown in FIG. 8, the cover member 45 is provided with a first claw 45a and a second claw 45b for fixing to the outer member 14. In the vicinity of the lighting device 46, there is little air flow and dew tends to adhere. Therefore, even if dew adheres, water droplets flow downward and are discharged from the slit 45d, so that the dew does not collect in the vicinity of the lighting device 46, and the structure is such that it is difficult to short-circuit.

The second claw 45b projects downward from the cover member 45 and has a hook-shaped portion at the tip. The hook-shaped portion of the second claw 45b is hooked on the hole provided in the lower part of the opening edge of the rear wall of the outer member 14. Next, the first claw 45a also has a hook-shaped portion at the tip, and the hook-shaped portion is fitted into a hole provided in the upper part of the opening edge of the rear wall of the outer member 14. As a result, the cover member 45 can be fixed to the opening edge formed on the rear wall of the outer member 14. When the cover member 45 is fixed to the outer shell member 14, the convex portion 45c of the cover member 45 presses the rib 43d of the translucent member 43, and the translucent member 43 is pressed against the opening edge of the outer shell member 14. At this time, since the seal member 42 interposed between the translucent member 43 and the outer shell member 14 is compressionally deformed, it is possible to maintain good airtightness in the chilled chamber 13 even if the outer shell member 14 is deformed. It has become.

In the present embodiment, since the translucent member 43 is elastically supported by the outer member 14, the pressure reducing pump is driven to reduce the pressure inside the chilled chamber 13, and even if the outer member 14 is deformed, the opening is opened. The airtightness of 41 can be maintained. Here, the area of the rear wall of the outer member 14 is smaller than the area of the side wall, the upper wall, and the lower wall of the outer member 14. Therefore, when the decompression load is uniformly applied to the outer member 14, the rear wall is most difficult to be deformed. Therefore, by providing the opening 41 on the rear wall, the amount of deformation can be reduced even when the pressure is reduced, and it is suitable for maintaining the airtightness by the cover member 45.

Further, a cold air return port for a chilled chamber is provided on the back side of the outer shell member 14, and the rear wall of the outer shell member 14 on which the lighting device 46 and the like are installed is close to the cold air return port. Further, since the chilled chamber 13 is sealed, there is almost no flow of cold air in the chilled chamber 13. Therefore, dew and frost are likely to occur on the rear wall surface of the outer member 14. However, when heat is generated by energizing the lighting device 46 having an LED substrate or the like, the rear wall surface can be kept warm, which also has the effect of preventing dew condensation.

Here, even when dew occurs, as shown in FIG. 6, the opening 41 is formed at the corner portion at the rear upper portion of the outer member 14, and the translucent member 43 and the lighting device 46 are oblique. Since it is attached to the lighting device 46, it is possible to prevent dew from flowing to the lighting device 46 side.

Further, in the present embodiment, although the lighting device 46 is located outside the outer member 14, a part of the translucent member 43 is exposed inward from the inner surface of the outer member 14, so that the lighting device 46 is used. Light easily spreads in the chilled chamber 13, and visibility is improved. Further, since the translucent member 43 is located behind the ceiling, even if the cylindrical portion 43a of the translucent member 43 is exposed inside the outer member 14, oil or the like is less likely to adhere. Since the peripheral side surface 43e below the cylindrical portion 43a of the translucent member 43 is textured, the light is softened.

Further, since the cover member 45 of the present embodiment is installed in a place where it is easy to see when working with the chilled chamber 13 at the time of manufacturing, the operator mistakenly hits a structure such as an inner box of the refrigerator at the time of assembly. It is difficult and has the effect of suppressing damage to the lighting device 46 and the like.

Further, a plurality of reinforcing ribs are formed on the outside of the outer member 14 of the present embodiment so as to withstand the pressure when the pressure is reduced, and the lighting device 46 is installed within the height range of the reinforcing ribs. There is. Therefore, the lighting device 46 can be installed without reducing the internal volume of the chilled chamber 13.
