In FIG. 2, it can be seen that a switching chamber 6 having a door 6 a is provided next to the ice making chamber 5 immediately above the freezing chamber 3.

  In FIG. 2, the storage container 11 is accommodated in a container cover 15, and rails 17 (so-called slide rails) are respectively attached to the outer sides of the upper ends of the left and right sides of the container cover 15. Is fixed to the back side of the door 3 a of the freezer compartment 3, and when the door 3 a is pulled forward, the container cover 15 is pulled out together with the rail 17 and the storage container 11. In addition, a so-called dish-shaped aluminum plate 19 having a rising portion at the peripheral portion is placed on the placing portion 11 d at the bottom of the storage container 11.

  FIG. 3 is an exploded perspective view of the freezer compartment 3 shown in FIG. As shown in FIG. 3, one end of the two rails 17 is firmly attached to an upper portion of the left and right ends on the back side of the door 3a of the freezer compartment 3 by an L-shaped bracket 81, a bolt 83, and the like. The container cover 15 is attached to the two rails 17 so that the container cover 15 is pulled out in conjunction with the door 3a.

  A hooking portion 15e that rises upward is formed at a rear position of the container cover 15, and a rising portion 15f that extends upward is also formed at the front end. An engagement hole 15g is formed in the rising portion 15f. The container cover 15 hooks a hook portion 15e on an upper portion of a rail 17 fixed to the back side of the door 3a of the freezer compartment 3, and engages an engagement hole 15g with an L-shaped hook portion 23 provided on the back surface of the door. Thus, the container cover 15 is detachably positioned.

  The two rails 17 are so-called double rail structures that are slidably fitted via rollers or bearings to other rails (not shown) attached to both side wall surfaces of the refrigerator-freezer body of the freezer compartment 3. As shown in FIG. 2, the freezer compartment 3 is pulled out largely together with the container cover 15 by sliding on the other rail.

  As shown in FIG. 3, the container cover 15 is formed with a bottom opening 15 a that opens largely to the bottom where the bottom of the storage container 11 hits when the storage container 11 is accommodated. The bottom opening 15a is smaller than the size of the flat portion of the bottom surface of the storage container 11. When the storage container 11 is accommodated in the container cover 15, the bottom surface of the storage container 11 is the edge of the bottom opening 15a. In this case, the bottom opening 15a is closed without a gap. This state will be described with reference to FIG.

  FIG. 4 shows a state in which the storage container 11 is accommodated in the container cover 15 and the bottom surface of the storage container 11 hits the edge of the bottom opening 15a of the container cover 15 and closes the bottom opening 15a. It is AA sectional drawing (refer FIG. 3) seen from the front side, and has shown the cross-sectional state of the both sides of the storage container 11 and the container cover 15. FIG.

  As shown in FIG. 4, the bottom surface of the storage container 11 accommodated in the container cover 15 is in contact with the peripheral edge of the bottom opening 15 a of the container cover 15 at the edge thereof. More specifically, the peripheral edge portion of the bottom opening portion 15a of the container cover 15 is formed with a short protruding rib portion 15b that is bent upward at its end portion. The projection 15b abuts against the bottom surface of the storage container 11 to support the storage container 11, and, as will be described later, expands the gap between the container cover 15 and the storage container 11 in the vicinity of the contact, The air layer is expanded.

  Further, in the storage container 11, the bottom surface of the outer portion of the portion of the container cover 15 with which the projecting portion 15b abuts rises upward, and the lower curved portion 11a is formed at the raised portion. The strength of the storage container 11 is increased and the protrusion 15b of the container cover 15 is abutted to be firmly supported. Further, by providing the lower curved portion 11a, the bottom corner of the storage container 11 is pushed upward, and an air layer in the gap is further formed between the storage container 11 and the container cover 15 at the corner. I try to expand.

  As shown in FIG. 4, support portions 27 are formed on the upper ends of the left and right sides of the storage container 11, and the container cover 15 is hooked on the rail 17 so as to cover the hook portion 15 e of the container cover 15. 15, the support portion 27 is positioned so that the left and right side surfaces of the container cover 15 and the left and right side surfaces of the storage container 11 are separated from each other, and a gap is provided between the storage container 11 and the container cover 15. Further, a cold air supply unit 21a for supplying cold air is provided in the gap (see FIG. 5).

  In this way, the air layer 21 for convection of air is formed between the left and right side portions of the container cover 15 and the left and right side portions of the storage container 11, and the heat insulation efficiency and refrigeration efficiency of the storage container 11 are increased by the air layer 21. And energy saving effect has been achieved.

  That is, the air layer 21 is intruded by cold air from above and convects the cold air, thereby preventing frost and freezing in the air layer 21 and promoting sublimation even if frost is formed in the air layer 21. In particular, even when the outside air enters the air layer 21 when the storage container 11 is pulled out by pulling the door 3a, the air is actively sent into the air layer 21. Since the upper side of the layer 21 is opened and the cold air outlet 31a is arranged above the storage container 11 as shown in FIG. 1, the generation of frost can be effectively suppressed even when moist air enters the air layer 21. .

  In addition, since the storage container 11 and the container cover 15 are brought into contact with each other below the air layer 21 to ensure a certain degree of sealing, even when the storage container 11 is pulled out and exposed outside the refrigerator. By suppressing the outside air from flowing through the gap between the storage container 11 and the container cover 15, it is possible to prevent the cool air inside the air layer 21 from escaping and to the heat insulating effect of the air layer 21. The container can be prevented from warming.

  As described above, the protrusion 15b is formed at the edge of the bottom opening 15a of the container cover 15, and the lower curved portion 11a of the bottom corner of the storage container 11 is formed, thereby forming the corner portion. The air layer 21 between the container cover 15 and the storage container 11 in FIG.

  In the above description with reference to FIG. 4, the inner side of the upper ends of the left and right sides of the container cover 15 is an air layer 21 that convects air between the left and right sides of the container cover 15 and the left and right sides of the storage container 11. However, the air layer 21 is not limited to the left and right side portions of the container cover 15 and the storage container 11, and is not shown, but the front side portion of the container cover 15 and the storage container 11 and It is also formed on the rear side, improving the heat insulation efficiency and the freezing efficiency of the freezer compartment 3 as a whole.

  That is, the inner sides of the upper ends of the front side portion and the rear side portion of the container cover 15 are in contact with the outer sides of the upper end portions of the front side portion and the rear side portion of the storage container 11, respectively. An air layer 21 for convection of air is formed between the rear side portion and the front side portion and the rear side portion of the storage container 11. Thus, by forming the air layer 21 between each side part of the container cover 15 and each side part of the storage container 11, and configuring the entire side surface of the freezer compartment 3 in a double structure, heat insulation efficiency and refrigeration efficiency And the temperature rise in the freezer compartment 3 when the door 3a of the freezer compartment 3 is opened and closed is suppressed.

  In addition, the bottom opening 15a is formed so as to cut out the bottom of the container cover 15, and the storage container 11 is accommodated in the container cover 15 so as to close the bottom opening 15a. Since the mounting portion 11d is provided in a concave shape on the bottom of the storage container 11 and the aluminum plate 19 is detachably mounted, the aluminum plate 19 made of aluminum having excellent thermal conductivity promotes the refrigeration effect of the storage object to be frozen. Moreover, by forming the bottom opening 15a in the container cover 15, the weight of the container cover 15, and thus the freezer compartment 3, can be reduced, and the door 3a can be easily opened and closed.

  In particular, since the protruding portion 15b is positioned and supported by the end portion of the mounting portion 11d, only the outside of the aluminum plate 19 is covered by the container cover 15, and the cold air flows downwardly throughout the aluminum plate 19 via the storage container 11. It is possible to cool it by applying it to the refrigeration and effectively promote freezing.

  Further, as shown in FIG. 3, a hook portion 23 having an L-shaped lateral cross section is formed in a portion near the upper portion of the center on the inner side on the door side. The storage container 11 is fitted into a rectangular opening 25 formed in a portion near the upper part of the center of the front portion disposed on the door side. And when the storage container 11 is put in the container cover 15, the opening part 25 of the storage container 11 is hooked by the hook part 23 which protruded from the engagement hole 15g of the container cover 15, and, thereby, the storage container 11 is in the front part. Is supported by the hook 23.

  As can be seen from FIG. 4, the upper ends of the left and right side portions of the storage container 11 are bent outward and bent slightly downward so as to cover the upper end portions of the left and right side portions of the container cover 15. A support portion 27 is formed that is supported on the upper end portion of the cover 15 by being hung from above. In addition, ribs (not shown) are appropriately provided inside the support portion 27 along the inner shape of the support portion 27 to increase the strength of the support portion 27 and to fit the container cover 15, that is, the fitted state. It ’s good.

  Accordingly, the storage container 11 is said that the support portions 27 at the upper ends of the left and right sides are hung on the upper ends of the left and right sides of the container cover 15 and the opening 25 is hooked on the hook portion 23 of the container cover 15. The container cover 15 is supported at three locations.

  Next, referring to FIG. 3, a plurality of slit-like vent holes 11b are formed in the upper portion of the upper left and right sides of the storage container 11, and a container cover 15 corresponding to the vent holes 11b is formed. A vent hole 15d in which a side wall portion between the hooking portion 15e and the rising portion 15f is notched is formed in a portion near the front surface of the upper part of the left and right side portions. The vent hole 11b and the vent hole 15d may be notched, slit-shaped, or punched holes (round holes, long holes).

  FIG. 5 shows a state in which the storage container 11 is accommodated in the container cover 15 and the bottom surface of the storage container 11 hits the edge of the bottom opening 15a of the container cover 15 to close the bottom opening 15a. It is BB sectional drawing (refer FIG. 3) seen from the front side, and has shown the cross-sectional state of the both sides which included the ventilation hole 15d of the container cover 15, and the ventilation hole 11b of the storage container 11.

  As shown in FIG. 5, when the storage container 11 is accommodated in the container cover 15, the vent hole 15d of the container cover 15 and the vent hole 11b of the storage container 11 are communicated at the same position. Cold air flows through the vent holes 15d and 11b, preventing the formation of icing and adhesion of frost in the air layer 21 formed between the container cover 15 and the storage container 11 described above.

  Further, as shown in FIG. 3, a notch 15c is formed in a large trapezoidal shape on the rear wall of the container cover 15, and is elongated on both the left and right sides of the upper end of the rear wall of the storage container 11. Although 11c is formed in two places on the left and right sides, cold air flows into the storage container 11 from the back of the freezer compartment 3 through these cutouts 15c and 11c, and cools the frozen storage in the storage container 11 It is supposed to be.

  That is, the cold air cooled by the cooler 51 is sent out by the fan 31, blown out from the upper rear part of the freezer compartment 3 through the cutouts 15c and 11c and into the storage container 11, and while being lowered in the storage container 11, it is covered. After the frozen stock is cooled, it flows out of the vent holes 11b and 15d described above, passes through the outside of both sides of the container cover 15, and flows out to the back of the freezer compartment 3 by the flow of cold air. Is cooled uniformly.
