The freezing chamber container has a double wall structure in which a lower part of the freezing container that is supported by the supporting device has an internal air layer.

  The storage of the third invention is a storage in which a freezing chamber container made of synthetic resin having an upper surface opening is supported in a freezing chamber having a front opening so as to be movable in the front-rear direction by a support device using a left and right rail or a combination of a rail and a roller. The freezing chamber container has a cold air inlet at the upper part of the rear wall and a cold air outlet at the upper part of the front wall, and the front wall, the rear wall, the left and right side walls, and the bottom of the bottom wall are separated from the cold air inlet and the cold air outlet. It is characterized by a double wall structure in which an air layer is formed.

  The storage of the fourth invention is a storage in which a freezing chamber container made of synthetic resin with an opening on the upper surface is supported in a freezing chamber with an opening on the front so as to be movable in the front-rear direction by a support device using a combination of left and right rails or rails and rollers. The freezer container has a cold air inlet at the upper part of the rear wall and a cold air outlet at the upper part of the front wall, and is supported by the support device, the cold air inlet, and the front wall and the rear wall that are out of the cold air outlet, The left and right side walls and the bottom wall have a double wall structure in which an internal air layer is formed.

  In the first invention, when the freezer container is pulled out of the freezer compartment, even if the wall of the freezer container in contact with the frozen food stored therein, for example, the bottom wall or the front wall is below freezing point, Due to the double wall of the wall and front wall, even if the outer surface of the bottom wall or front wall touches the outside air, the internal air layer contributes to the improvement of heat insulation performance, thereby suppressing the temperature rise of frozen food. The For this reason, when the freezer compartment is stored again in the freezer compartment, the temperature rise in the freezer compartment is reduced, the freezing operation time for cooling the frozen food to a predetermined low temperature is also reduced, and an energy saving effect can be expected.

  In the second aspect of the invention, in the configuration in which the freezer compartment container is supported by the left and right support devices so as to be movable in the front-rear direction, the lower part off the portion supported by the support device has a double wall structure. The support device for the freezer compartment, which has the wall structure, can be applied as it is, and the same effects as the first invention can be achieved without changing the structure of the support device.

  In the third aspect of the present invention, when a cold air inlet is provided in the upper part of the rear wall and a cold air outlet is provided in the upper part of the front wall in order to circulate the cooler into the freezer compartment, the front wall and the rear wall are separated from the cold air inlet and the cold air outlet. Since the left and right side walls and the bottom wall have a double wall structure, the structure of the cold air inlet and the cold air outlet can be designed so as not to be restricted by the double wall structure, and the same effects as the first invention can be achieved. Will be able to.

  In the 4th invention, the storage provided with the outstanding freezer compartment container which had the effect of 2nd invention and 3rd invention can be provided.

  The present invention provides a double-wall structure in which a freezer compartment container made of a synthetic resin having an upper surface opening is supported in a freezer chamber having a front opening so as to be retractable and retractable in the front-rear direction and the lower part of the freezer compartment container has an internal air layer. Examples of the present invention will be described below.

  Next, an embodiment in which the storage of the present invention is a refrigerator-freezer will be described. 1 is a longitudinal side view of a refrigerator-freezer, FIG. 2 is a front view of a refrigerator-freezer body, FIG. 3 is a perspective view of a freezer compartment container, FIG. 4 is an exploded perspective view of the freezer compartment container, and FIG. FIG. 6 is a longitudinal side view showing a cold air inlet portion to the freezer compartment container, and FIG. 7 is an exploded perspective view of an exterior box having a double wall structure at the lower part of the freezer compartment container. .

  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 supported by the left and right rails 22 or a support device 20 including a combination of the rails 22 and rollers 23, and the freezer compartment 5. The front opening is opened and closed by a pull-out door 9 supported by the support device 20 so as to be movable in the front-rear direction together with the freezer compartment 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. Returning from the cold air inlet 45 at the lower back of the freezer compartment 5 so that it is cooled again by the evaporator (cooler) 7, the same circulation is performed. 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 becomes easy to put frozen food into and out of the freezer compartment 10. The support member 21 is provided with a stopper portion for restricting the pull-out door 9 to be pulled forward so that the support member 21 is not detached from the support by the roller 23 due to 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 main container 10 </ b> A is supported by the support device 20, so that the freezer compartment container 10 serves as the auxiliary container 10 </ b> B. This can be shared with the support of the freezer compartment container 10 in the form of a single container, 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 top opening of the main container 10A, and the bottom surface of the auxiliary container 10B enters the main container 10A. It will be in the state covered with 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, the cold air inlet 25 of the main container 10A is attached with an opening / closing plate 28 maintained by the left and right shaft support portions 28A so that the cold air inlet 25 is always closed by a spring force or its own weight. Yes. 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 28 </ b> A is pivoted to a substantially horizontal state to open the cold air inlet 25. 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.

  Further, as the drawer-type door 9 is pulled forward, the freezer compartment container 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 spring force or its own weight. 3, the cold air inlet 25 is kept closed as shown in FIG. 3, so that the cold air in the main container 10A is prevented from escaping from the cold air inlet 25 in the pulled-out state.

  By the drawer as described above, the main container 10A and the auxiliary container 10B are both pulled out to the front of the refrigerator-freezer main body 2 and exposed to the outside air. At this time, if the frozen food is stored in the main container 10A and the auxiliary container 10B, the walls of the main container 10A and the auxiliary container 10B that are in contact with the frozen food remain at a temperature below zero. The temperature of the frozen food stored inside increases. Therefore, in the present invention, in order to prevent this, the lower part of the container has a double wall structure. In this case, since the auxiliary container 10B has a shallow container form, the surface area exposed to the outside air is narrow, but the main container 10A has a deep container form, and therefore its front wall 10A2, rear wall 10A1, left side wall 10A3, right side wall 10A4. And the surface area of the bottom wall 10A5 is large, the surface area exposed to the outside air is widened, and this phenomenon is likely to appear. For this reason, the main container 10A is mainly formed into a double wall structure having an internal air layer. This double wall structure does not use the inside of the double wall as a cold air duct, but provides heat insulation performance as a sealed space.

  As described above, since the main container 10A is supported by the support device 20, a double-wall structure is required, so that the indication structure must be changed, and the cost is increased, which is not preferable. In addition, the frozen food stored in the main container 10A is placed mainly on the bottom wall 10A5, and the lower part of the front wall 10A2, the rear wall 10A1, the left side wall 10A3, and the right side wall 10A4, except when it is fully stored. And the part remains cooled below zero. For this reason, the outer shell wall 31 is placed on the outer surface of the main container 10 with a space (inner air layer 30) on the outer periphery of the main container 10 so that the lower part of the main container 10 has a double wall structure having the inner air layer 30. It is set as the combination attached to. Of course, the same applies to the case of the freezer compartment container 10 constituted only by the main container 10A without providing the auxiliary container 10B.

Further, since the left side wall 10A3 and the right side wall 10A4 are placed and supported on the support member 21 of the support device 20, the double wall structure has a lower front wall 10A2 that is separated from the supported part, and a rear side. The wall 10A1, the left side wall 10A3, the right side wall 10A4, and the bottom wall 10A5 have a double wall structure in which the internal air layer 30 is formed. For this reason, even if the wall of the freezer compartment that is in contact with frozen food is below freezing point, this wall is a double wall, so that the inner air layer is insulated even if the outer surface of the wall touches the outside air. By contributing to the performance improvement, the temperature rise of the frozen food is suppressed. Therefore, the temperature rise of the freezer compartment 5 when the freezer compartment 10 is again stored in the freezer compartment 5 is reduced, the freezing operation time for cooling the frozen food to a predetermined low temperature is also reduced, and an energy saving effect can be expected. . Moreover, since it is a double wall structure in the lower part of the support apparatus 20, there also exists an effect that the support apparatus of the freezer compartment container which was a single wall structure can be applied as it is.

  Further, since the rear wall 10A1 is provided with the cold air inlet 25 and the front wall 10A2 is provided with the cold air outlet 26, the lower rear wall 10A1, the front wall 10A2, the left side wall 10A3, the right side which is out of the cold air inlet 25 and the cold air outlet 26, The wall 10A4 and the bottom wall 10A5 have a double wall structure in which an internal air layer 30 is formed. For this reason, the outer wall of the bottom wall 10A5 and the surrounding wall is not cooled by the frozen food due to the internal air layer 30, so that frost adheres to the outer surface and no icy ice is formed. There is no risk of hindrance. Moreover, since the structure of the cold air inlet 25 and the cold air outlet 26 is not influenced by the double structure, the structure of the cold air inlet 25 and the cold air outlet 26 can be formed in a preferable state.

  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. It can be applied to refrigerators and freezer containers.
