The main container 10A is placed on the support member 21. By pulling the pull-out door 9 forward, the main container 10A, the auxiliary container 10B, and the lid 10C are pulled out together with the support member 21. For this reason, if the lid 10C is removed in this pulled out state, the frozen food can be easily taken in and out of the auxiliary container 10B, and if the auxiliary container 10B is removed together with the lid 10C, the frozen food can be easily taken in and out of the main container 10A.

  As described above, the freezer compartment container 10 is supported by the support device 20. In this case, the left and right side walls 10A3 and 10A4 of the main container 10A are supported by the support device 20, so that this support structure is used as the freezer compartment. The container 10 can be shared with the support of the freezer container 10 in the form of a single container in which the auxiliary container 10B is not provided, and the cost of the support device 20 can be reduced. Further, since the main container 10A is supported by the support device 20, it is easy to detachably support the entire freezer compartment container 10 including the auxiliary container 10B.

  The main container 10A includes a cold air inlet 25 at the upper part of the rear wall 10A1 of the main container 10A, and a cold air outlet 26 at the upper part of the front wall 10A2 of the main container 10A. The cold air inlet 25 is formed in a notched state in which the upper portion of the rear wall 10A1 is recessed at a position lower than the auxiliary container 10B, and the cold air outlet 26 is in a state in which a plurality of vertically long holes are formed at substantially equal intervals in the horizontal direction. Is formed. A cold air outlet 27 is provided on the back wall of the freezer compartment 5 so as to protrude forward. The cold air blown out from the cold air outlet 27 is supplied by the blower 8 with the cold air cooled by the evaporator (cooler) 7.

The bottom surface of the main container 10A enters the main container 10A, and the upper surface opening of the main container 10A is almost covered with the auxiliary container 10B. In order to maintain the state where the auxiliary container 10B is placed at a predetermined position of the main container 10A, the front end portions of the left and right flanges 10AH of the main container 10A are provided at the front end portions of the left and right support portions 10B5 of the auxiliary container 10B. A locking projection 10BT that fits into the locking recess 10AU formed in the above is provided. Thus, in the state where the auxiliary container 10B is placed at a predetermined position of the main container 10A, the auxiliary container 10B prevents the cold air in the main container 10A from escaping upward. In addition, the bottom surface of the auxiliary container 10B also serves as a cold air guide while the cold air entering the main container 10A from the cold air inlet 25 flows out from the cold air outlet 26.

  Also, a lid 10C is detachably mounted on the upper end of the left and right wall 10BP of the auxiliary container 10B so as to cover the upper surface opening of the auxiliary container 10B. In this case, protrusions are provided on the upper surface of the left and right walls 10BP of the auxiliary container 10B or the lower surface of the lid 10C with a space in the front and rear, and the protrusions provide a space between the lid 10C and the upper surfaces of the left and right walls 10BP of the auxiliary container 10B. If a slight gap is formed, it is possible to prevent the auxiliary container 10B and the lid 10C from being combined by freezing and becoming difficult to separate.

  The auxiliary container 10B is formed by forming a portion 10B1 in which a part of the front wall (right side in the front view in the figure) is notched backward so that tall frozen food can be stored in the main container 10A. A region R where the auxiliary container 10B does not exist is formed in a part of the front portion. For this reason, a tall article can be stored in the region R. This is used to store tall items such as milk cartons in this region R when the combination of the main container 10A and the auxiliary container 10B as described above is used as the vegetable compartment container 40. It is convenient.

  The lid 10C covers the upper surface opening of the auxiliary container 10B, and the main container 10A, the auxiliary container 10B, and the cover 10C are pulled out integrally by pulling the pull-out door 9 forward. In this pulled out state, the lid 10C serves to prevent cold air leakage in the auxiliary container 10B, suppresses the temperature rise of the frozen food in the auxiliary container 10B, and the upper surface opening of the main container 10A is covered with the auxiliary container 10B. Therefore, the temperature rise of the frozen food in the main container 10A is also suppressed. Further, in this pulled out state, the auxiliary container 10B is covered with the lid 10C, and the auxiliary container 10B is slid rearward on the left and right flanges at the upper end of the upper opening of the main container 10A, thereby allowing the frozen food in the main container 10A to be frozen. However, since the upper surface opening of the auxiliary container 10B is covered with the lid 10C, the temperature rise of the frozen food in the auxiliary container 10B is suppressed.

  As shown in FIG. 3, an opening / closing plate 28 maintained by the shaft support portion 28A is attached to the cold air inlet 25 of the main container 10A so that the cold air inlet 25 is always closed by a spring force or a force of its own weight. The freezer compartment container 10 (the main container 10A and the auxiliary container 10B in the figure) placed on the support member 21 moves toward the predetermined storage position of the freezer compartment 5 by closing the pull-out door 9, and this As the main container 10A moves toward the back of the freezer compartment 5 toward the storage position, the cold air outlet 27 comes into contact with the opening / closing plate 28, and the opening / closing plate 28 resists the spring force or the acting force of its own weight. Is pushed forward by the cold air outlet 27. In the state where the drawer door 9 closes the front opening of the freezer compartment 5 and the freezer compartment container 10 is stored in a predetermined position of the freezer compartment 5, the open / close plate 28 in FIG. As shown, the shaft support portion 28A is pivoted to a substantially horizontal state and the cold air inlet 25 is opened. In this state, the cold air supplied from the cold air outlet 27 flows into the main container 10 </ b> A and flows out of the cold air outlet 26 into the freezer compartment 5. The cold air that has flowed into the freezer compartment 5 circulates back to the evaporator (cooler) 7 through a suction port provided in the lower part of the back wall of the freezer compartment 5 or the like. Moreover, since the opening / closing plate 28 is rotated to a substantially horizontal state as shown in FIG. 6, the front end of the opening / closing plate 28 does not move forward from the rear wall 10A1 of the main container 10A. Therefore, the rotation of the opening / closing plate 28 is not obstructed.

  Further, as the drawer-type door 9 is pulled forward, the freezer compartment 10 is pulled forward, so that the cold air outlet 27 is separated from the opening / closing plate 28 along with this drawing, and the opening / closing plate 28 has the spring force or Since the cold air inlet 25 is kept closed as shown in FIG. 3 by the action force of its own weight, the cold air in the main container 10A is prevented from escaping from the cold air inlet 25 in the pulled-out state.

That is, since the auxiliary container 10B is placed on the left and right flanges 10AH of the main container 10A as described above, the auxiliary container 10B is slidable in the front-rear direction on the main container 10A. Then, when the auxiliary container 10B is slid rearward with the lid 10C on, the upper opening of the main container 10A is opened widely, the left and right first support parts 10B5 are the left and right flanges of the main container 10A. 10AH, the rear portion of the auxiliary container 10B is a second support portion 10B6 formed at a position above the left and right support portions 10B5 (in the drawing, the one behind the second support portion 10B6 formed at the front and rear). Then, the freezing chamber 5 is placed on the front and rear support rails 5L provided on the left and right side walls 5A. For this reason, it becomes easy to take in and out the stored food in the main container 10A.

  Further, in this case, when the auxiliary container 10B is slid rearward with the lid 10C placed thereon and the auxiliary container 10B is moved rearward until it is disengaged from the left and right flanges 10AH of the main container 10A, the front and rear second support portions Since 10B6 is placed on the front and rear support rails 5L provided on the left and right side walls 5A of the freezer compartment 5, the upper surface opening of the main container 10A is opened entirely, making it easier to take in and out stored foods. .

  In the state where the freezer compartment container 10 is pulled out integrally with the drawer-type door 9 and the auxiliary container 10B is placed at a predetermined position of the main container 10A, when the stored food is taken in and out of the auxiliary container 10B, the lid 10C is removed. By sliding backward from the auxiliary container 10B, the upper surface opening of the auxiliary container 10B is greatly opened. In this case, the front portion of the lid 10C is placed on the upper ends of the left and right walls 10BP of the auxiliary container 10B, but the rear portion of the lid 10C is formed on the left and right sides of the lid 10C.
