The present invention relates to a refrigerator having a freezer compartment in which freeze drying of frozen food is reduced.

For example, there is provided a freezer storage of an upper opening type having an inner cover made of foamed styrol and the like in addition to the outer cover. This kind of inner cover is mainly used for the low temperature type freezer storage, and it is to save energy by suppressing the discharge of cold air in the refrigerator and suppressing the temperature rise in the refrigerator.

In addition, as an invention for suppressing an increase in the freezer temperature, a cold storage material is also provided on the inner surface of the outer lid (on the inner lid) and the inner wall of the reservoir as in JP-A-9-303931.

Subsequently, the home refrigerator includes a refrigerating compartment, which is cooled at a refrigerating temperature, a vegetable compartment, and a freezing compartment, which is cooled at a refrigerating temperature. In general, the lower the cooling temperature is, the longer the preservation period of frozen food is. A jet port is provided to blow cold air at about -30 ° C directly into the storage container (for example, Japanese Patent Laid-Open No. 2004-69253).

However, in the case of using an inner cover such as foamed plastic, cold air discharge can be suppressed by installing the cover. However, once the temperature in the freezer rises, the temperature inside the freezer does not drop at all due to the heat insulation of the cover. It was not a composition.

In addition, in the case where the coolant is provided on the inner cover and the inner wall, the temperature stability in the freezer is improved due to the effect of the coolant, but the use of the coolant increases the overall weight or decreases the storage volume in the freezer.

By the way, in a storage container stored in a freezer compartment of a refrigerator, no inner cover such as foamed styrol is provided and no cold storage material is installed, and very cold air (for example, -30 ° C) is directly blown from the evaporator to food. Since a lot of water is sublimated in the frozen food when cooked and eaten the frozen food, there is a problem that the food is dull and the texture is greatly reduced.

However, in the structure of the conventional freezer compartment, since cold air is directly blown into the container containing the frozen food, the bag containing the food is cooled rapidly, and the temperature difference between the bag and the food increases, thereby subliming the moisture of the food, In the frozen food contained in the bag by the so-called freeze-drying phenomenon, which is attached to the frost, the moisture is sublimed a lot and the frost is attached to the inner circumferential surface of the bag, such that there is a problem in that the surface or the edge of the frozen food is dried. As such, when the frozen food is freeze-dried, when the frozen food is cooked and eaten, there is a problem that the food is heavily deteriorated and the texture is greatly deteriorated. In order to prevent the freeze-drying phenomenon as described above, an indirect cooling method employed for cooling the vegetable compartment may be implemented. However, the freezer compartment needs to be cooled to a low temperature of −18 ° C. or lower, and only the indirect cooling may freeze a predetermined frozen food. There is a possibility that it cannot be cooled to the temperature zone and cannot be frozen.

The present invention has been made in view of the above, and an object of the present invention is to provide a refrigerator which can prevent the drying of the stored food by the sublimation of moisture of the frozen food with a simple structure while optimally preserving the frozen food.

Further, the present invention has been made in view of the above circumstances, and an object thereof is to preserve a refrigerator capable of suppressing sublimation of moisture in frozen foods with a simple structure while optimally storing frozen foods.

The present invention relates to a refrigerator having a box-shaped storage container housed in a freezing section and in which cold air from an evaporator is blown into the interior from an opening on an upper surface thereof, the refrigerator being mounted on the storage container and mounted from the evaporator in a mounted state. It is to install a non-sealing cover body having a thermal conductivity to block the cold air from blowing directly into the interior from the opening of the storage container.

Moreover, in order to solve the said subject, this invention provides the freezing chamber cooled by the freezing temperature by the cold air blown out from the cold air ejection opening provided in the back surface, the storage container which opened the upper surface installed in the said freezing chamber, and the at least said storage container. The upper surface opening of the rear surface which opposes a cold air jet opening is closed by the cover body.

Between the refrigerator compartment 3A and the vegetable compartment 4A is partitioned up and down by the partition board 11A, and inside the vegetable compartment 4A, the vegetable storage container 12A connected to the inner surface side of the vegetable compartment door 8A is accessible. Is housed.

Between 4A of vegetable chambers, 5 A of switching chambers, and the freezing chamber for ice-making which is not shown in figure, it is partitioned up and down by 13 A of heat insulation partition walls integrally provided in 2 A of heat insulation boxes.

Between the switching chamber 5A and the freezing chamber for ice making and the freezing chamber 6A, the insulating partition wall is partitioned up and down by the insulating insulating wall 14A, and the insulating partition wall not shown is also shown between the switching chamber 5A and the ice-making freezing chamber. It is partitioned to the left and right, and 5 A of switch chambers are comprised by the form which is spatially and thermally independent from another chamber by this. In the switching chamber 5A, a storage container 15A connected to the inner surface side of the switching chamber door 9A is housed so as to be accessible.

In the freezer compartment 6A, a storage container 16A connected to the inner surface side of the freezer compartment door 10A is housed so as to be accessible.

On the other hand, as shown in FIG. 2, the refrigeration cycle apparatus 17A is assembled in the back part of 1A of refrigerator main bodies. That is, a refrigerator compartment evaporator chamber (hereinafter referred to as "R evaporator chamber") 18A is formed in the rear side portion of the vegetable chamber 4A, and a refrigeration cycle device (18A) is formed in the R ever chamber 18A. A refrigerating chamber blower (19A) provided with a refrigerating chamber evaporator (hereinafter referred to as " R Ever ") constituting 17A), and positioned at the top thereof and capable of varying the variable speed (for example, 1800 to 2400 rpm). Hereinafter, "A room fan" (20A) is provided. In the state where the R chamber fan 20A is driven, the cold air generated by the R ever 19A is supplied to the refrigerating chamber 3A and the vegetable chamber 4A, and then returned to the lower part of the R ever chamber 18A. The circulation is to be carried out. Moreover, 21 A of defrost heaters for R ever are provided in 18 A of R ever chambers.

In addition, 22 A of freezer compartment evaporator chambers (henceforth "Fever chamber") are formed in 5 A of switching chambers, and the back side part which spreads above and below the ice-making freezer compartment and freezer compartment 6A which are not shown in figure. In the ever chamber 22A, a freezer evaporator (hereinafter referred to as “F-aver”) 23A constituting the refrigeration cycle device 17A is provided, and is positioned at the top thereof to enable variable speed driving (for example, 1800-2400 rpm) freezer blowing fan (hereinafter referred to as "F chamber fan") 24A is provided. In addition, 25 A of defrost heaters for F ever are provided below 23 A of F ever.

Here, the downstream side (discharge side of cold air) of the F chamber fan 24A installed in the F chamber 22A is branched into a cold air passage connected to the switching chamber 5A, and a cold air passage connected to the freezing chamber 6A. In the cold air flow path connected to 5 A of switching chambers, the damper 26A for switching chambers opened and closed controlled by the control apparatus which is not shown in figure is provided.

When the F chamber fan 24A is driven while the switching chamber damper 26A is closed, the cold air generated by the F-aver 23A is supplied to the freezing chamber 6A and the freezing chamber for ice making (not shown), and then F The circulation which returns to the lower part in 22 A of ever seals is performed. On the other hand, when the F chamber fan 24A is driven with the switching chamber damper 26A open (or partially open), not only the cool air is supplied to the freezing chamber 6A and the freezing chamber for ice making but also into the switching chamber 5A. After supplying the water, circulation to return to the lower part in the F-average 22A is performed again.

27A of machine rooms are formed in the lower back part of the refrigerator main body 1A, The compressor 28A which comprises the refrigeration cycle apparatus 17A is provided in the machine room 27A, and the compressor 28A and illustration are shown. A cooling fan 29A for cooling the condenser that has not been provided is provided. The compressor 28A is driven at variable speed by inverter control (for example, the operating frequency of the inverter is 30 to 70 Hz), and the cooling fan 29A is also driven at variable speed (for example, 1800 to 2000 rpm). It is supposed to be.

In addition, in FIG. 1 which shows the storage container 16A accommodated in the freezer compartment 6A, the opening 16Aa of the storage container 16A is equivalent to a rapid storage plate (cover body) concerning this invention. 30A) is mounted, and the rapid storage plate 30A blocks almost half of the inside of the opening 16Aa of the storage container 16A. This rapid cooling plate 30A is made by integrating a 0.8 mm aluminum plate 32A with a frame 31A made of resin, and is attached to the rail portion 33A provided in the opening 16Aa of the storage container 16A. This makes it possible to slide from the closed position shown in FIG. 1 to the inwardly open position shown in FIG. 3 and to stop by a stopper not shown in the open position. In this case, as shown in FIG. 5, when the storage container 16A in which the rapid storage plate 30A is in the open position is returned to the freezing chamber 6A, the rapid storage plate 30A is formed on the inner wall of the freezing chamber 6A. It is adapted to slide from the open position to the closed position by being pressed. Accordingly, when the storage container 16A is located in the freezer compartment 6A, the rapid storage plate 30A blocks the cold air blown from the F-average 23A to the storage container 16A by the opening 16Aa. Is located inside).

Subsequently, the operation of the above configuration will be described.

When food is stored in the freezer compartment 6A, as shown in Fig. 4, the freezer compartment door 10A is taken out to take out the storage container 16A, and if necessary, as shown in Fig. 5, a rapid storage plate ( After storing food in the storage container 16A with 30A slide inward, the storage container 16A is stored in the freezer compartment 6A. As a result, almost half of the inside of the opening 16Aa of the storage container 16A is blocked by the rapid storage plate 30A, so that cold air from the F Ever 23A is received by the rapid storage plate 30A and then the storage container 16A ), And the food in the storage container 16A can be cryopreserved for a long time.

By the way, while frozen food can be eaten with a good texture when cooked while maintaining the frozen state of moisture in the food, frozen food has a problem of deterioration of the texture due to sublimation of water.

The reason why water is sublimed from frozen food is due to the following phenomenon. That is, as shown in Fig. 6A, since the frozen food 34A is usually packaged in the storage bag 35A, the storage bag 35A is stored in the cold air from the F-aver 23A in the state stored in the freezing chamber 6A. Is exposed, and the temperature of the storage bag 35A is the lowest. That is, when the target temperature of the freezing chamber 6A is -18 ° C and the temperature of the cold air is -30 ° C, the temperature of the storage bag 35A can be regarded as -30 ° C while the temperature of the frozen food is -18 ° C. Thus, in the state where the temperature of the storage bag 35A is much lower than that of the frozen food 34A, the water sublimed from the frozen food 34A adheres to the inner surface of the storage bag 35A as a frost (see FIG. 6A). In this case, as a result, the entire moisture sublimed from the frozen food 34A adheres to the inner surface of the storage bag 35A as a frost, and as a result, the saturated steam density in the storage bag 35A does not increase, and moisture is released from the frozen food 34A. Subsequently, the sublimed water is attached to the inner surface of the storage bag 35A as a frost. As a result of this phenomenon, since the moisture of the frozen food 34A moves to the inside of the storage bag 35A, much moisture is sublimed from the frozen food 34A.

In addition, when the temperature of the freezer compartment 6A rises due to defrosting operation or the like and the temperature of the frozen food 34A falls below the temperature of the air in the storage bag 35A, the frost attached to the storage bag 35A sublimates. At this time, the frozen food 34A is attached as frost (see FIG. 6B). When the temperature of the storage bag 35A is lower than that of the frozen food 34A again by the blowing of cold air, the castle attached to the surface of the frozen food 34A is sublimated to adhere to the inside of the storage bag 35A.

As a result of the repetition as described above, a lot of moisture is moved from the frozen food 34A to the inside of the storage bag 35A. For this reason, when cooked and eat | maintained the frozen food 34A which sublimed water in this way, a food will permute and a texture will worsen significantly.

On the other hand, in this embodiment, since the inside part through which cold air from the F ever 23A blows in the opening 16Aa of the storage container 16A is interrupted by the rapid storage plate 30A, it is blown to the storage container 16A. The cold air is once received by the rapid storage plate 30A and then blown into the storage container 16A. As a result, the strength of the cold air blown into the storage container 16A is significantly reduced compared to the configuration in which cold air is directly blown into the storage container 16A, and thus the inside of the storage container 16A can be cooled almost uniformly, and the frozen food ( The cooling can be performed so that the temperature difference between 34A) and the storage bag 35A does not increase.

Thus, even when the frozen food 34A and the storage bag 35A are cooled so that the temperature difference does not increase, moisture is sublimed from the frozen food 34A. However, since the temperature of the frozen food 34A and the storage bag 35A is the same, the frozen food is frozen. The water sublimed from the food 34A adheres not only to the inner surface of the storage bag 35A but also to the surface of the frozen food 34A. That is, even if the water is sublimated from the frozen food 34A, part of the water is returned to the frozen food 34A, so that the sublimation of the water from the frozen food 34A and the return to the castle to the frozen food 34A are balanced. The sublimation of moisture from the frozen food 34A is stopped.

In addition, when the temperature of the storage bag 35A becomes higher than the temperature of the frozen food 34A by the defrosting operation, the frost attached to the storage bag 35A is sublimated and adheres to the surface of the frozen food 34A. When the temperature with the storage bag 35A is lower than the temperature of the frozen food 34A due to the blowing of cold air, the temperature difference between the frozen food 34A and the storage bag 35A does not become large. The attached frost does not completely move to the inner surface of the storage bag 35A, and moisture from the frozen food 34A does not sublimate.

Therefore, since the movement of moisture from the frozen food 34A is stopped, when the frozen food 34A is cooked and eaten, turbidity is eliminated, and it can be eaten with a good texture. Furthermore, the food becomes a porous phase by drying, and it can also suppress the oxidation (so-called discoloration by freezing) promotion of the food component by the surface area increasing.

Moreover, 30 A of rapid cooling plates are formed with aluminum (Thermal conductivity is 237 W / (m * K)), and the rapid cooling plate 30A is made into very low temperature (-) by blowing air from the F Ever 23A. 30 ° C.) can be cooled in a short time, so that the food placed below the rapid storage plate 30A can be efficiently cooled by radiation.

In addition, since the rapid storage plate 30A does not completely close the opening 16Aa of the storage container 16A, the sublimed moisture is stored even if the frost is attached to the inside of the storage container 16A during the defrosting operation. It can discharge to the outside of the container 16A, and can prevent frost accumulating.

According to such a structure, the cold air blown from the F ever 23A in the opening 16Aa of the storage container 16A accommodated in the freezer compartment 6A is blocked by the rapid storage plate 30A, and the cold air is stored in the storage container 16A. Since the air is not directly blown, the temperature in the storage container 16A can be made almost uniform. Therefore, the temperature difference between the frozen food 34A accommodated in the storage container 16A and the storage bag 35A for packaging the same can be reduced, and the sublimation of moisture from the frozen food 34A can be prevented from continuing. Deterioration of the texture when cooking and eating frozen food 34A can be prevented.

In addition, the constitution having such an excellent effect is solved only by forming the rapid cold storage plate 30A from aluminum, so that the weight of the rapid storage plate 30A is not excessively heavy and the storage volume of the storage container 16A is small. It can carry out without losing a cost significantly.

(2nd embodiment)

Subsequently, a second embodiment of the present invention will be described with reference to FIGS. 7 and 8. The second embodiment is characterized in that the rapid storage plate is made almost the same size as the opening of the storage container.

As described in the first embodiment, the rapid storage cooling plate 30A is provided to weaken the strength of the cold air blown from the F ever 23A. Ideally, however, the size is preferably as large as possible. In the case where the opening 16Aa of the container 16A is completely closed, cooling of the storage container 16A to food is only radiation of the rapid storage plate 30A, and the food in the storage container 16A cannot be cooled sufficiently. There is concern.

Therefore, in this embodiment, in FIG. 7 which shows 16 A of storage containers, the shape of the rapid storage plate 41A matches the shape of the opening part 16Aa of the storage container 16A, and the aluminum plate 42A. ), A plurality of long holes 43A having a width of, for example, 5 mm are formed in the periphery, and the fast storage plate 41A having such a configuration is placed on the upper surface of the storage container 16A with the closed position shown in FIG. It is made to be slidably mounted between the opening positions shown in FIG. In this case, the rapid storage plate 41A is non-closed with respect to the storage container 16A due to the presence of the long hole 43A.

Since the cooling of the cold air to the storage container 16A is performed through the long hole 43A of the rapid storage plate 41A, the strength of the cold air blown to the storage container 16A can be greatly reduced, and the storage container 16A is provided. The frozen food 34A stored in the refrigerator can be cooled so that the temperature difference from the storage bag 35A does not increase. In addition, although the air blowing amount of the cold air blown into the storage container 16A is small compared with the first embodiment, since the area of the rapid storage plate 41A is large, the food is efficiently cooled by the cooling of the rapid storage plate 41A. Can be cooled.

According to such a configuration, since most of the openings 16Aa of the storage container 16A are blocked by the rapid storage plate 41A, the strength of the cold air blown to the storage container 16A can be sufficiently weakened. Similarly, the frozen food 34A can be sufficiently cooled while suppressing the sublimation of moisture in the frozen food 34A. In this case, since the rapid storage plate 41A is slidably installed on the upper surface of the storage container 16A, the rapid storage plate 41A is slid according to the amount of the frozen food 34A accommodated in the storage container 16A. The frozen food 34A can be easily stored in the storage container 16A.

(Third embodiment)

Subsequently, a third embodiment of the present invention will be described with reference to FIGS. 9 and 10. The third embodiment is characterized by enabling the rapid storage plate to be bent in the middle.

In FIG. 9 which shows 16 A of storage containers, the quick storage plate 51A is comprised by connecting two aluminum plates 52A with the connection member which is not shown in figure, and can be bend | folded centering on an intermediate part. In addition, an elongated hole 53A is formed in the peripheral portion of the aluminum plate 52A. In this case, in the state where the rapid storage plate 51A is mounted in the opening 16Aa of the storage container 16A, as shown in FIG. 10, the frozen food 34A is lifted by lifting the aluminum plate 52A located in front of it. ) Can be stored in the storage container 16A.

According to such a configuration, since most of the openings 16Aa of the storage container 16A are blocked by the rapid storage plate 51A, the strength of the cold air blown to the storage container 16A can be sufficiently weakened. Similarly, the frozen food 34A can be sufficiently cooled while suppressing sublimation of moisture in the frozen food 34A. In this case, since the quick accumulating plate 51A is provided to be bent at an intermediate portion, the quick accumulating plate 51A is bent or lifted up in accordance with the amount of frozen food 34A to be stored in the storage container 16A. The frozen food 34A can be easily stored in the storage container 16A.

(4th Embodiment)

Subsequently, a fourth embodiment of the present invention will be described with reference to FIGS. 11 to 14. In the fourth embodiment, the rapid storage plate 51A of the third embodiment can be formed smaller than the inner shape of the storage container 16A and positioned in the storage container 16A.

As shown in FIG. 11, when the amount of the frozen food 34A in the storage container 16A is small, as shown in FIG. 12, when the rapid storage plate 51A is placed into the storage container 16A, the rapid storage plate is rapidly cooled. The 51A is placed on the frozen food 34A. In this state, when the cold air from the F-average 23A is blown into the storage container 16A, the blowing of the cold air into the frozen food 34A is blown through the long hole 53A of the rapid storage plate 51A. The space blocked by the rapid storage plate 51A can be cooled almost uniformly. In this case, since the rapid storage plate 51A is in contact with the storage bag 35A of the frozen food 34A, the cooling efficiency by the radiation of the rapid storage plate 51A can be maximized.

In addition, when the amount of the frozen food 34A in the storage container 16A is large, as shown in FIG. 13, the rapid storage plate 51A is the opening 16Aa of the storage container 16A as shown in FIG. Located in the to block the opening (16Aa).

According to such a configuration, since the quick storage plate 51A is inserted into the storage container 16A, the freezing efficiency of the frozen food 34A can be increased by the copying of the rapid storage plate 51A.

(5th Embodiment)

Subsequently, a fifth embodiment of the present invention will be described with reference to FIGS. 15 and 16. In the fifth embodiment, the sub storage container is provided in the storage container 16A, and the present invention is implemented only in the sub storage container.

In FIG. 15 showing the storage container 16A, the storage container 16A has the sub storage chamber 61A, and only the sub storage chamber 61A is shown in FIG. 16 as shown in FIG. The 51A can be inserted. Therefore, as shown in FIG. 16, the frozen food 34A has a large influence due to the sublimation of water or a long-term preservation, so as to be cooled by the rapid storage plate 51A. It becomes possible.

I install it freely. The cover body 70 closes the rear part of the opening portion 54 so that the cool air ejected from the first cold air ejection port is not directly blown into the storage container 50.

As shown in FIG. 20, the recessed part 52 is formed in the all 51 of the storage container 50, and the decoration 53 is attached to the recessed part 52. As shown in FIG.

The inner surface on both sides of the flange portion 55 has a substantially U shape so as to be sandwiched between the retracting portion 56 extending downward from the outer circumference of the flange portion 55 and the outer circumferential wall of the storage container 50. The molded reinforcing member 57 is attached with a screw 58.

Rails are applied to the rear portions on both sides of the flange portion 55 so as to slide the lid 70 back and forth between the flange portion 55 and L to regulate the upward movement of the lid 70. A rising part in which a locking member 61 formed in a shape of a child is erected and installed and inclined upwardly to facilitate taking out the cover body 70 in front of the locking member 61 as shown in FIG. 25. (62) is formed.

Ribs 63a and 63b for positioning the lid 70 are placed up and down on the flange portion 55 located ahead of the front end of the locking member 61, respectively. As shown in FIG. 24, the flange portion 55 located at the rear side engages the recessed portion of the inner surface side of the lid 70 to stop the lid 70 from moving backward by a predetermined distance or more. Is installing.

In addition, the bottom surface 53 of the storage container 50 is positioned so that it does not move in the door opening operation or the like when the cover body 70 removed as shown in FIG. 23 is placed on the bottom surface 53. The rib 53a to be performed is erected and installed.

Then, the cover body 70 is explained in full detail. FIG. 26 is a plan view showing the lid 70, FIG. 27 is an exploded view of the lid of FIG. 26, FIG. 28 is a perspective view from below showing the lid of FIG. 26, and FIG. 29 is a corner portion of FIG. 30 is a cross-sectional view along the line AA of FIG. 26, FIG. 31 is a cross-sectional view along the line CC of FIG. 26, and FIG. 32 is a cross-sectional view along the line DD of FIG. 26.

As shown in Figs. 26 and 27, the cover body 70 is formed of, for example, a metal plate 71 made of aluminum or the like, and a synthetic resin formed in a lo shape, covering the outer periphery of the metal plate 71, for example. For example, it is comprised by the frame 75 made from ABS, and the metal plate 71 is provided with the positioning through-hole 72 near the center of each edge | side. The frame 75 is composed of an upper frame 75a and a lower frame 75b, and as shown in FIGS. 27, 30, and 32, the through frame of the metal plate 71 is formed in the lower frame 75b. Ribs 76 are inserted to pass through the 72 to position the ribs 72. Thus, the cover body 70 covers the upper frame 75a in the state which inserted the through-hole 72 of the said metal plate 71 into the rib 76 of the lower frame 75b, for example, an ultrasonic wave It is integrally formed by welding.

In addition, when the freezer compartment temperature such as a freezer compartment is low, each member contracts, and the shrinkage amount of the resin frame 75 is greater than that of the metal plate 71, so that the outer circumferential surface of the metal plate 71 and the inner circumferential surface of the frame 75 are different from each other. Clearances larger than the shrinkage difference, for example, about 0.4 to 1 mm are provided between the through holes 72 and the ribs 76.

As shown in FIG. 28, FIG. 31, the convex part 78 which contact | connects the stopper 64 of the storage container 50 to the center part of the right and left side of the inner surface of the cover body 70 to restrict the back movement of the cover body 70 is shown. ), And the groove portion 77 in which the stopper 64 slides before and after the convex portion 78 is formed. In addition, ribs 63b are inserted into the front and rear ends of the groove portion 77 to drill the cut portions 79 for positioning the lid 70.

The convex portion 78 and the groove portion 77 are provided to be symmetrical forward and backward, and the cover body 70 is attached to the storage container 50 in any direction.

Subsequently, the operation of the lid 70 will be described with reference to FIGS. 18, 19, 21, and 22.

As shown in FIGS. 18 and 21, in the state in which the lid 70 is mounted on the storage container 50, both side edges of the lid 70 are mounted on the flange portion 55, and the lid body ( The entirety of 70 and the cutout 79 are positioned in contact with each of the ribs 63a and 63b. At this time, the stopper 64 is located in the groove portion 77 of the lid 70.

When the user takes out the frozen food, the storage container 50 is drawn out of the refrigerator by pulling out the door 19 as shown in FIG. 19, but if the cover body 50 is present, it is difficult to take out the frozen food, so the cover body Move 50 backward. At this time, the rib 63b is peeled off the cutout 79 to be moved backward by lifting the front of the lid 50 while lifting the front, and the stopper 64 slides in the groove 77. While the cover body 70 moves backward. And if it moves back to a predetermined distance, the convex part 78 of the cover body 70 will contact with the stopper 64, and the fall of the cover body 70 back is prevented. In addition, the lid 70 is in contact with the locking member 61 to prevent the lid 70 from falling from the storage container 50 at the time of movement, thereby restricting the movement in the up, left, and right directions.

After the user removes the frozen food, the lid 70 is moved forward to contact the ribs 63a and 63b with all and the cutouts 29 and closes the door, but the user forgets to return to the front position. In addition, the rear end surface of the cover body 70 comes into contact with the rear wall to automatically close the cover body 70 to close the opening 54.

In addition, when storing a long length of frozen food or a user who does not need the use of the present invention, the cover 70 by pulling out all of the cover body 70 inclined forward with the shape of the rising portion 62. The side edge of the sliding member 61 slides inside the locking member 61, and the restriction of the locking member 61 is released to remove it from the storage container 50.

At this time, the width of the lid 70 is less than or equal to the depth of the storage container 50, and the depth of the lid 70 is less than or equal to the width of the storage container 50. As shown in the drawing, it can be installed on the bottom surface 54 of the storage container 50. For this reason, the cover body 70 can be quickly attached as needed, and when it is unnecessary, it can arrange | position to the bottom face of the storage container 50, and loss of the cover body 70 can be prevented. Or by using the cover body 70 as a metal plate, the refrigerating ability can be improved as a cooling panel.

Subsequently, the operation of the present invention will be described. In general, frozen foods can be eaten with a good texture when cooked while maintaining a frozen state of moisture in the food, but frozen foods have a problem of deterioration of texture due to sublimation of moisture.

The reason why water is sublimed from frozen food is due to the following phenomenon. That is, as shown in FIG. 39, since the frozen food 90 is usually packaged with a storage member 91 such as a bag, a saran wrap, a tupper, or the like, the frozen food 90 is stored in the first freezing chamber 5. In the stored state, the temperature of the storage member 91 is lowest because the cold air flow from the cold air jet port 31 directly contacts the storage member 91. That is, when the target temperature of the first freezing chamber 5 is -18 ° C and the temperature of cold air is -30 ° C, the temperature of the storage member 91 is -30 ° C while the temperature of the frozen food 90 is -18 ° C. Can be regarded as.

In this way, when the temperature of the storage member 91 is much lower than the frozen food 90, the water sublimed from the frozen food 90 adheres to the inner surface of the storage member 91 as frost. In this case, all the water sublimed from the frozen food 90 adheres to the inner surface of the storage member 91 as a result of frost, and as a result, the density of saturated water vapor in the storage member 91 does not increase, and moisture is released from the frozen food 90. Subsequently, the sublimed water adheres to the inner surface of the storage member 91 as a frost. As a result of this phenomenon, since the moisture of the frozen food 90 is moved to the inside of the storage member 91, a lot of moisture is sublimed from the frozen food 90.

In addition, in the defrosting operation, the temperature of the first freezing chamber 5 rises due to the infiltration of warmed air by the energization of the F ever defrosting heater 25, and the temperature of the frozen food 90 is increased by the storage member 91. When the temperature is lower than the temperature in the air), the frost attached to the storage member 91 is sublimated, and this time, as shown in FIG. 40, the frozen food 90 is attached as the frost. When the operation is started, the temperature of the storage member 91 decreases more rapidly than the frozen food 90 again by the blowing of cold air, and sublimates to the castle attached to the surface of the frozen food 90 to form the inside of the storage member 91. Will be attached.

By the repetition as described above, a lot of moisture is moved from the frozen food 90 to the inside of the storage member 91. For this reason, when cooked and eaten the frozen food 90 sublimed in this way, the food is permuted and the texture is greatly deteriorated.

In contrast, in the present embodiment, the rear portion of the opening portion 54 of the storage container 50 through which the cool air generated by the F Ever 23A is blown from the cold air jet port 31 provided above the rear surface of the storage container 50 is covered. Since it is closed by the 70, the cool air blown from the cold air blower outlet 31 installed on the rear surface of the storage container 50 is blocked by contacting the cover body 70 to ventilate and circulate the upper surface of the storage container 50 by ventilation. . As a result, the strength of the cold air in contact with the frozen food is significantly reduced compared to the configuration in which cold air directly contacts the frozen food in the storage container 50, so that the temperature difference between the frozen food 90 and the storage member 91 does not increase. Can be cooled.

On the other hand, the water sublimates from the frozen food 90 no matter how cooled, but the water sublimed from the frozen food 90 is preserved by cooling so that the temperature difference between the frozen food 90 and the storage member 91 does not increase. It is attached to the surface of the frozen food 90 as well as the inner surface of the 91. That is, even if the water is sublimated from the frozen food 90, a part of the water is returned to the frozen food 90, so that the sublimation of water from the frozen food 90 and the return to the frost to the frozen food 90 are balanced. The sublimation of moisture from the frozen food 90 is stopped.

In addition, when the temperature of the preservation member 91 becomes higher than the temperature of the frozen food 90 after defrosting, the frost attached to the preservation member 91 is sublimated and adheres to the surface of the frozen food 90. If the temperature of the storage member 91 is lower than the temperature of the frozen food 90 due to the blowing of cold air, the temperature difference between the frozen food 90 and the storage member 91 does not become large. The attached frost does not completely move to the inner surface of the storage member 91, and moisture does not sublimate from the frozen food 90.

In addition, the cover body 70 may lower the temperature rise of the frozen food 90 during the defrosting operation in order to suppress the infiltration of warm air during the defrosting operation into the storage container 50. For this reason, even if the temperature of the storage member 91 decreases sharply after the start of the cooling operation, the temperature difference with the frozen food 90 can be kept small, whereby the sublimation of moisture from the frozen food 90 can be suppressed.

Therefore, since the movement of moisture from the frozen food 90 is stopped, when the frozen food 90 is cooked and eaten, turbidity is eliminated, and the food can be eaten with a good texture. Further, the food becomes a porous phase by drying, and the promotion of oxidation (so-called discoloration by freezing) of food ingredients due to the increase in the surface area can also be suppressed.

In addition, the first freezer compartment is a drawer-type storage chamber in which the storage container 50 is drawn out by the door opening operation, and the lid 70 is made to slide the upper surface of the storage container 50 toward the rear. It can be set as one structure, and the opening-closing operation | movement of the cover body 70 can be made easy, and it can make it easy to enter and leave frozen food. Further, even if the user forgets to return the lid 70 to the original state after removing the frozen food, the rear end of the lid 70 comes into contact with the rear wall of the refrigerator or the like due to the backward movement of the container 50 by the door closing. The opening 54 of the storage container 50 can be closed.

In addition, the storage container 50 of the present invention is provided with a locking member 61 for restricting the movement of the cover body 70 in the upper direction, and to release the restriction of the locking member by sliding the cover body forward. In this case, when the lid 70 is not necessary, the lid 70 can be easily removed from the storage container 50, and it can be prevented from inadvertently falling from the storage container 50 when the lid 70 is moved.

In addition, in the present invention, the cover member 70 can be easily moved from the storage container 50 by sliding forward to ride over the positioning unit by providing an upwardly rising inclined portion 62 inclined upwardly in all of the catching members 61. I can remove it.

In addition, the present invention prevents the rear cover from falling backward when the lid 70 is moved backward by providing a stopper 64 that restricts the rearward movement of the lid 70 or more in the storage container 50. can do.

In addition, according to the present invention, the inner surface of the lid 70 has a groove portion 77 in which the stopper 64 of the storage container 50 slides when the lid 70 is moved backwards, and the lid 70 is predetermined. When moving backward by distance, by providing the convex part 78 which contacts the stopper 64, the cover body 70 can be moved back and forth with a simple structure.

In addition, since the groove part 77 and the convex part 78 of the cover body 70 are provided symmetrically in the front and rear, when attaching again in the state which the user detached, it can be attached in either front or back, and usability improves. do. In addition, in this embodiment, although the groove part 77 was provided only in the inner surface of the lid | cover body 70, it can be attached to either of the outer surfaces by providing also in the surface.

In addition, when the synthetic container such as polypropylene, which is easy to bend, is used in the storage container 50, the flange portion 50 may be extended outward so that the front and rear movement of the lid 70 may not be possible. By providing the reinforcement member 57 which suppresses curvature at the side of the container 50, the cover part 70 can be prevented from bending, and the sliding property can be improved.

In addition, as shown by the broken line of FIG. 18, since all the cover body 70 is inclined upwards, the cold air blown from the rear can be directed upwards, so that the direct blow of the cold air into the storage container 50 is further increased. Therefore, the temperature difference between the frozen food 90 and the storage member 91 can be reduced, thereby preventing sublimation of moisture from the frozen food 90.

In addition, according to the present invention, the cover body 70 is made of the metal plate 71, and the cover body 70 is cooled at a very low temperature, for example, -30 ° C by a short time by blowing cold air from the F ever 23A. Since it can cool, the food located under the cover body 70 can be cooled efficiently by radiant heat.

Accordingly, the storage container 50 is blocked by blocking the cold air blown from the F ever 23A from the opening portion 54 of the storage container 50 accommodated in the first freezing chamber 5 by the cover body 70 by the metal plate 71. Since the cold air is not directly blown in the inside), the temperature in the storage container 50 can be made almost uniform. For this reason, the temperature difference between the frozen food 90 accommodated in the storage container 50 and the storage member 91 for packaging the same can be reduced, and the sublimation of moisture from the frozen food 90 can be prevented from continuing. It is possible to prevent the deterioration of the texture when cooking and eating the frozen food 90.

In addition, if the metal plate 71 is moved back and forth with a wet hand or the like, there is a possibility that the moisture on the surface of the hand may freeze. However, in the present invention, the cover body 70 may be moved between the metal plate 71 and the outer circumference of the metal plate 71. By using the frame 75 made of a resin to be covered, the frame 75 having a large specific heat from the metal plate 71 is used as a handle of the cover 70, so that the cover body 70 can be moved back and forth. You can surely prevent freezing of your hands.

In the case where the freezing chamber temperature such as a freezing chamber is low, the metal plate 71 and the frame 75 shrink and the shrinkage of the resin frame 75 is larger than that of the metal plate 71. When the frame 75 is brought into close contact with each other, there is a possibility that damage such as deformation or cracking may occur. Therefore, in this invention, the said damage can be prevented by providing a clearance gap between the outer peripheral surface of a metal plate, and the inner peripheral surface of an edge.

In addition, according to the present invention, the width of the lid 70 is less than or equal to the depth of the storage container 50, and the depth of the lid 70 is less than or equal to the width of the storage container 50. 70 may be installed on the bottom surface 54 of the storage container 50. For this reason, the cover body 70 can be attached quickly as needed and the loss of the cover body 70 can be prevented.

Subsequently, another embodiment will be described with reference to FIGS. 33 to 35. In this embodiment, the cover body 70 makes the whole surface of the opening part 54 of the storage container 50 close. As described above, if the cover member 70 is present, the cooling air is not directly blown, and thus cooling is insufficient. However, if cooling is not insufficient due to the freezing capacity or the blowing amount, the entire surface is as shown in FIGS. 33 and 34. It is good also as a closing cover body 70. In this case, it is preferable that a gap is provided between the storage container 50 instead of being completely sealed, or a hole through which cold air passes through the upper surface of the metal plate 71.

In addition, when the width of the lid 70 is greater than or equal to the depth of the storage container 50 or the depth of the lid 70 is greater than or equal to the width of the storage container 50, the lid 70 is used. ) Width is less than or equal to the depth of the storage container 80 provided in the second storage compartment 6, as shown in Figure 35, the depth of the lid is the width of the storage container It can be set to the bottom surface 81 of the storage container 80 by the following. For this reason, the cover body 70 can be mounted quickly as needed like the case where it mounted in the said storage container, and the loss of the cover body 70 can be prevented. Or by using the cover body 70 as a metal plate, the refrigerating ability can be improved as a cooling panel.

On the other hand, in the above embodiment, the opening is closed over the entire width of the storage container. However, as shown in Figs. 36 to 38, a cover 70 is provided in a part of the storage container to provide a storage space having the effect of the present invention. You may also

Specifically, for example, a partition 83 for partitioning the storage space in the left-right direction is installed in the upper container 82 of the storage container 80 of the second freezing chamber 6 from the bottom surface, and another inner wall is provided. The flange portion 84 is placed upright, and the lid body 70 mounts the lid body 70 by moving the upper surface of the partition 83 and the flange portion 84 in the same manner as in the above embodiment. The storage portion can be a storage space having the effect of the present invention. In this case, the user can distinguish and store only foods requiring cooling and foods to be prevented from drying by sublimation of moisture, thereby improving usability of the user.

In addition, the said structure is only one Embodiment and various changes are possible in the range which does not change the summary of this invention. For example, the cover body 70 is not limited to the form which slides the upper surface of a storage container, but may be attached to the refrigerator main body 1, such as formed in an inner box, and cold air may be directly connected to the storage container 50. The shape of the cold air jet port 31 may be inclined upward so as not to penetrate the inside.

(Industrial availability)

The present invention is applicable to a refrigerator having a freezer compartment which is cooled to a freezing temperature.

According to the present invention, since the cold air from the evaporator is not directly blown by the non-closed cover body to the frozen food stored in the storage container, the strength of the cold air is greatly reduced and blown by the cover body, so that the temperature in the storage container can be almost uniform. have. In this case, since the lid has thermal conductivity, the inside of the storage container can be efficiently cooled even by the radiation of the lid.

As a result of uniformizing the temperature in the storage container, the difference in temperature between the frozen food packaged with the storage bag and the storage bag is reduced, and the movement of moisture due to the temperature difference is eliminated, so that sublimation of moisture from the frozen food can be suppressed. Can be. As a result, when the frozen food is cooked, it is possible to prevent the food from deteriorating.

Further, according to the present invention, since the cold air is not blown directly to the frozen food in the storage container by the cover body, the frozen food stored in the storage container can be prevented from rapidly cooling a bag containing the frozen food. Therefore, the temperature difference between the frozen food and the bag becomes small, and the movement of moisture due to the temperature difference is suppressed, so that it is possible to prevent the sublimation of moisture from the frozen food and to prevent drying.
