FIG. 6 is a longitudinal sectional side view showing a cold air inlet portion to the freezer compartment container, and FIG. 7 is a transverse plan view showing a mounting portion of the cold air leakage suppression plate.

  The refrigerator-freezer 1 which concerns on Example 1 is the structure which partitions off the inside of the refrigerator-freezer main body 2 of front opening, and forms several storage chambers, and the front surface of each of these storage chambers can be opened and closed by each door. The refrigerator-freezer main body 2 has a heat insulating structure in which a foam heat insulating material 2C is filled between an outer box (outer wall plate) 2A and an inner box (inner wall plate) 2B. A refrigerator compartment 3, a freezer compartment 5, and a vegetable compartment 4 are partitioned from the top in the freezer main body 2, and the front opening of the refrigerator compartment 3 is closed by a left and right open door 3 </ b> A.

  Reference numeral 6 denotes a refrigerant compressor installed in a machine room provided at the bottom of the refrigerator-freezer body 2. The refrigerant compressed by the compressor 6 is condensed by a condenser 42 and passes through a decompression unit such as a capillary tube to be evaporated. After evaporating in the (cooler) 7, circulation is performed by returning to the compressor 6 and compressing again, and these constitute a refrigeration cycle. 8 is a blower that circulates the cold air cooled by the evaporator (cooler) 7 to the refrigerator compartment 3, the vegetable compartment 4, and the freezer compartment 5.

  In the freezer compartment 5, a synthetic resin freezer compartment container 10 having an upper opening is provided in the freezer compartment 3 having a front opening so as to be retractable in the front-rear direction. In order to make it easy to pull out and store the freezer compartment 10 in the front-rear direction, the left and right side walls of the freezer compartment 10 are placed on the left and right sides of the freezer compartment 5 by the support device 20 using the left and right rails 22 or the combination of the rails 22 and rollers 23. The front opening of the freezer compartment 5 supported by the side wall 5A is opened and closed by a pull-out door 9 supported on the left and right side walls 5A of the freezer compartment 5 by the support device 20 so as to be movable in the front-rear direction together with the freezer compartment container 10. The illustrated support device 20 is configured such that the rail portions 22 of the left and right support members 21 extending horizontally from the back side of the door 9 are placed on rollers 23 attached to the left and right walls of the freezer compartment 5. The freezer compartment 10 is mounted on left and right support members 21 with flange portions on both the left and right sides of the freezer compartment 10 so as to be removable upward.

  The front opening of the vegetable compartment 4 is closed by a drawer-type door 41 that is drawn forward together with a vegetable container 40 supported so as to be able to be drawn out in the front-rear direction by a support device using left and right rails and rollers provided in the vegetable compartment 4. . A cold air supply passage 43 in the vertical direction is formed between the back wall 44 of the refrigerator compartment 3 and the inner box (inner wall plate) 2B of the back wall of the refrigerator body 2.

  The cold air cooled by the evaporator (cooler) 7 is circulated by an air blower 8 as shown by an arrow. That is, the cold air sent out from the blower 8 is supplied to the freezer compartment 5 from the cold air outlet 27 on the back of the freezer compartment 5 and flows into the freezer compartment 10 as will be described later. The same circulation is performed by returning from the cold air suction port 45 at the lower back of the freezer compartment 5 so as to be cooled again by the evaporator (cooler) 7. Further, the cold air sent from the blower 8 is supplied to the cold air supply passage 43 through the damper device 46, distributed to the cold air passages 43 </ b> A formed on the left and right sides of the cold air supply passage 43, and formed on the back wall 44 of the refrigerator compartment 3. The cold air outlet 47 is supplied to the refrigerator compartment 3.

  The cold air supplied to the refrigerating room 3 is sucked from a cold air suction port 48 formed at one side lower part of the back wall 44 of the refrigerating room 3, and flows downward through a cold air passage 50 formed at the rear of the freezing room 5. It blows out to the vegetable compartment 4 from the cold air outlet 51 opened at the rear part of the compartment 4. The cold air blown into the vegetable compartment 4 indirectly cools the vegetables and the like in the vegetable container 40 with most of the cold air and directly cools it with a part of the cold air that enters, and is placed at the top of the vegetable compartment 4 or the rear of the vegetable compartment 4. It returns so that it may be cooled again by the evaporator (cooler) 24 from the open cold air inlet 52, and the same circulation is performed.

  With such a configuration, the support member 21 is pulled out by pulling the pull-out door 9 forward, so that the freezer compartment container 10 placed on the support member 21 is pulled out, and the upper surface opening of the freezer compartment container 10 is frozen. Since it is located in front of the refrigerator body 2, it is easy to put frozen food into and out of the freezer compartment 10. In addition, the support member 21 is provided with a stopper portion that restricts the pull-out of the pull-out type door 9 so that the support member 21 is not detached from the support by the roller 23 by the forward pull-out.

  The freezer compartment container 10 has an opaque main container 10A having a deep upper surface opening, and a shallow upper surface transparent that is slidable in the front-rear direction and detachably mounted on the left and right flanges at the upper end of the upper surface opening of the main container 10A. The auxiliary container 10B includes a transparent plate-like lid 10C that is detachably mounted on the peripheral edge of the auxiliary container 10B so as to cover the upper surface opening of the auxiliary container 10B. 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 auxiliary container 10B is placed on the left and right flanges at the upper end of the upper surface opening of the main container 10A, and the bottom surface enters the main container 10A. The upper surface opening of the main container 10A is almost auxiliary. It will be in the state covered with the container 10B. For this reason, the auxiliary container 10B prevents the cool air in the main container 10A from escaping upward. In addition, 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.

  The lid 10C covers the upper surface opening of the auxiliary container 10B, and the main container 10A, the auxiliary container 10B, and the lid 10C are pulled out integrally by pulling the pull-out door 9 forward. 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. The temperature rise of the frozen food within 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 placed on the support member 21 moves toward a predetermined storage position of the freezer compartment 5 by closing the pull-out door 9, so that the main container 10A faces the freezer compartment toward this storage position. 5, the cold air outlet 27 comes into contact with the opening / closing plate 28, and the opening / closing plate 28 is pushed forward by the cold air outlet 27 against the spring force or the force of its own weight. 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.

  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.

  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.

  In addition, when the lid 10C is detachably mounted on the upper ends of the left and right walls of the auxiliary container 10B so as to cover the upper surface opening of the auxiliary container 10B, there is a space in the front and back on the upper surface of the left and right walls of the auxiliary container 10B. If the projection is provided and the lid 10C is placed on the projection, it is possible to prevent the auxiliary container 10B and the lid 10C from being combined by freezing and difficult to separate.

  In the present invention, the freezer compartment container 10 is supported by the support device 20 integrally with the drawer-type door 9 so that it can be pulled out and housed in the left and right side walls 5A of the freezer compartment 5 in the front-rear direction. The side walls 10A3 and 10A4 are supported by the support device 20. In this configuration, in order to suppress cold air leakage from the space between the left and right side walls 5A of the freezer compartment 5 and the left and right side walls of the freezer compartment 10 below the support device 20, as shown in FIGS. The cold air leakage suppression plate 60 is attached to the left and right side walls 5A of the freezer compartment 5 for a long time.

  The cold air leakage suppression plate 60 is a synthetic resin in which a rigid fixing portion 60A and a flexible side 60B extending from the front end of the fixing portion 60A so as to approach or contact the left and right side walls of the freezer compartment 10 are integrally formed. A hard fixing portion 60 </ b> A is attached to the front portion of the left and right side walls 5 </ b> A of the freezer compartment 5 by a fixture 61 such as a screw. In this state, most of the gap between the left and right side walls 5 </ b> A of the freezer compartment 5 below the support device 20 and the left and right side walls of the freezer compartment 10 is closed at the front portion of the freezer compartment 5. become.

  For this reason, when the pull-out door 9 is opened and the freezer compartment container 10 is pulled out, the flexible side 60B suppresses cold air leakage in the freezer compartment 5, that is, suppresses the entry of outside air into the freezer compartment 5, While suppressing the temperature rise of the freezer compartment 5, frost adhesion to the evaporator (cooler) 7 due to the entry of outside air can be reduced, and the cooling performance of the evaporator (cooler) 7 is hardly lowered, and the evaporator (cooler). The number of times of defrosting 7 can be reduced.

  Due to the flexibility of the flexible side 60B, even when the cold air leakage suppression plate 60 and the left and right side walls of the freezer compartment container 10 are in contact with each other, there is little resistance when the drawer type door 9 and the freezer compartment container 10 are pulled out and stored. Will not be adversely affected. In addition, since the flexible side 60B extends from the front end of the fixed portion 60A so as to be close to or in contact with the left and right side walls of the freezer container 10, the flexible side 60B covers the fixed portion 60A so as not to be seen from the front. The appearance of this portion can be covered, which is preferable in terms of design effect. Furthermore, since the fixing portion 60A and the flexible side 60B are made of an integrally molded synthetic resin, it is easy to attach to the left and right side walls 5A of the freezer compartment 5 and handling becomes easy.

  In the above embodiment, the freezer compartment container 10 is composed of the main container 10A and the auxiliary container 10B. However, the same configuration can be applied to the structure in which the auxiliary container 10B is not provided and only the main container 10A is provided.

  The refrigerator-freezer of the present invention is not limited to the above-mentioned embodiment, and the form of the freezer and the form of the freezer container are not limited to the above-mentioned forms, and various forms of freezing are possible without departing from the technical scope of the present invention.
