Further, the storage container 18 is mounted across the receiving members 60 on both the left and right sides. Alternatively, the storage container 18 is fixed to the receiving member 60 or the freezer compartment door 29 with screws or the like. Therefore, when the freezer compartment door 29 and the receiving member 60 are pulled out, the storage container 18 is also pulled out together with them. The positional relationship between the container 18 and the freezer compartment door 29 is fixed.

As shown in FIG. 6, the storage container 18 is a box-shaped container. A front wall 80, which is the front wall portion of the storage container 18, has a central portion in the left-right direction that is a forward protruding wall portion 81 that protrudes forward when viewed from the outside of the storage container 18. When viewed from the inside, it is a recess that is concave toward the front). The forward protruding wall portion 81 is inserted between the left and right inner side stepped portions 54 .

As shown in FIGS. 4 and 6, the height of the forward protruding wall portion 81 is lower than the downward inclined surface 76 of the convex portion 72 on the inside of the freezer compartment door 29 . The forward projecting wall portion 81 is close to the bottom surface 75 of the recessed portion 74 of the freezer compartment door 29 . Note that the forward projecting wall portion 81 may be in contact with the bottom surface 75 of the concave portion 74 .

Further, the forward projecting wall portion 81 is lower than the surrounding wall portion of the storage container 18 .

A front storage area 83 projecting forward is formed in the storage container 18 at the front by such a forward projecting wall portion 81 . The front storage area 83 is below the protrusion 72 of the freezer compartment door 29 . Therefore, cold air flowing from the rear to the front in the freezer compartment 28 hits the downward inclined surface 76 of the projection 72 and flows toward the front storage area 83 .

Further, as shown in FIG. 6, a protrusion 82 projecting upward is provided on the bottom of the front storage area 83 of the storage container 18 . This protrusion 82 is used for fixing the freezing device 40 which will be described below.

As shown in FIGS. 7 and 8, the freezing device 40 is arranged in the front storage area 83 inside the storage container 18 along the front projecting wall portion 81 which is a part of the front wall 80 of the storage container 18 . ing. Therefore, at least part of the freezing device 40 is housed in the front storage area 83 . Also, at least part of the freezing device 40 is contained in the recess 74 inside the freezer compartment door 29 . It can also be said that the freezing device 40 is provided along the freezer compartment door 29 .

In addition, the fact that a certain object A is along another object B means that A is arranged parallel or nearly parallel to B so that A does not separate from B. When it is said that A follows B, A and B may be in contact with each other, or there may be a space between A and B or another object may exist. When we say that A is along B, it is permissible that there is a distance between A and B equal to the thickness of the thicker of A and B, and that there may be another object at that distance. Permissible.

Also, the freezing device 40 is positioned lower than the projection 72 of the freezer compartment door 29 . Therefore, the cold air that flows forward from the rear and hits the downward inclined surface 76 of the projection 72 hits the freezing device 40 below.

The freezing device 40 is a device that rapidly cools and freezes the stored items 42 using the antifreeze liquid 19 . Here, the antifreeze liquid 19 is a liquid that does not freeze even at a freezing temperature and maintains fluidity. Examples of the items 42 to be stored in the freezer 40 include foods such as meat, seafood, processed foods, vegetables, and fruits.

As shown in FIGS. 11 and 12, in the freezing apparatus 40, a first member 44 on the front side (that is, on the freezer compartment door 29 side) and a second member 45 on the rear side (that is, inside the refrigerator) serve as connecting portions. It has an outer shell container that is connected by a hinge 46 .

As shown in FIG. 11, the first member 44 includes a first box-shaped member 55 having a thin thickness in the front-rear direction and having a rearward opening, and a first box-shaped member 55 covering the first box-shaped member 55 from the rear (opening side). and a first fixing member 56 . As shown in FIGS. 11 and 12, the first fixing member 56 has an opening 47 in the center which is slightly smaller than the rear opening of the first box-shaped member 55 . This opening 47 is also the rear opening of the first member 44 . The first fixing member 56 is fixed to the first box-shaped member 55 by fixing means such as nails, screws, adhesive tape, or the like.

As shown in FIGS. 11 and 13, the second member 45 includes a second box-shaped member 57 having a thin thickness in the front-rear direction and a forward opening. and a second fixing member 58 covering from the side). The second fixing member 58 has an opening 77 in the center that is slightly smaller than the front opening of the second box-shaped member 57 . This opening 77 is also the front opening of the second member 45 . The second fixing member 58 is fixed to the second box-shaped member 57 by fixing means such as nails, screws, adhesive tape, or the like.

These members that make up the outer shell container are, for example, synthetic resins, synthetic resins containing thermally conductive fillers (such as alumina or boron nitride), or metals with high thermal conductivity (such as aluminum or heat It is made of a metal with higher conductivity than aluminum).

The first member 44 and the second member 45 can be opened and closed with a hinge 46 as an axis. In this embodiment, the hinge 46 shall be in the lower part of the 1st member 44 and the 2nd member 45. As shown in FIG. Therefore, the first member 44 and the second member 45 are opened and closed at the top.

In addition, "the first member 44 and the second member 45 open and close" may be expressed as "the outer shell container opens and closes". Further, "the first member 44 and the second member 45 are closed" or "the outer shell container is closed" means that the front open end of the second member 45 and the rear open end of the first member 44 are brought into contact or close to each other. means to

The thickness of the outer shell container at the thickest point in the closed state (that is, the length in the front-rear direction) is not limited, but as an example, it is 1/3 of the shorter of the vertical and horizontal lengths of the outer shell container. It is below.

As shown in FIG. 11, inside the first member 44, a flat heat regenerating agent 50 having a wide plane perpendicular to the front-rear direction is arranged. The cold storage agent 50 is, for example, a flat container filled with a medicine (for example, a medicine containing water and a polymer) and frozen. be.

A metal plate 51 is arranged behind the cold storage agent 50 so as to close the rearward opening 47 of the first member 44 . The metal plate 51 is preferably made of aluminum or a metal having a higher thermal conductivity than aluminum (eg, copper). The metal plate 51 is in contact with the first fixing member 56 from the front. The metal plate 51 has a slightly larger area than the rear opening 47 of the first fixing member 56 . Therefore, the metal plate 51 does not come off rearward from the first fixing member 56 .

On the other hand, an antifreeze bag 52 is accommodated inside the second member 45 . The inside of the antifreeze bag 52 is filled with the antifreeze 19 . The antifreeze bag 52 has a size that fits just inside the second member 45 when viewed in the front-rear direction.

As shown in FIGS. 13 and 14, when the antifreeze bag 52 is viewed from the front and back direction, a portion of the outer periphery (four side portions) (for example, two opposite left and right sides of the four sides) has , ear portions 53 are formed. The ear portion 53 is formed by extending an elastic thin film constituting the antifreeze bag 52 outward. The antifreeze bag 52 is fixed inside the second member 45 by sandwiching the ear portion 53 between the second box-shaped member 57 and the second fixing member 58 .

More specifically, when the second box-shaped member 57 is viewed from the front-rear direction, a portion of the outer periphery (four sides) (for example, as shown in FIG. 15, two opposing sides of the four sides) ) is provided with a plate-like holding plate 48 extending outward. In addition, a part of the outer peripheral portion (four side portions) when the second fixing member 58 is viewed from the front and rear direction (for example, two opposing side portions among the four sides as shown in FIG. 16) also A plate-shaped holding plate 49 extending outward is provided. The ears 53 of the antifreeze bag 52 are sandwiched between the holding plates 48 and 49 . Further, the holding plates 48 and 49 are covered with the cover 39 to prevent the holding plates 48 and 49 from separating from the ears 53 .

The first box-shaped member 55 and the first fixing member 56 are also provided with holding plates similar to the holding plates 48 and 49, respectively. These holding plates are covered with a cover 39 similar to the cover 39 described above. Thereby, the first box-shaped member 55 and the first fixing member 56 are fixed more firmly.

The antifreeze bag 52 is made of an elastic thin film impermeable to the antifreeze 19 . In addition, the antifreeze bag 52 is preferably made of a stretchable thin film having high stretchability, high recovery, and high puncture strength. Specifically, as will be described later, the antifreeze bag 52 has elasticity that allows it to expand and contract so as to conform to the outer shape of the storage item 42 when the storage item 42 is pressed against it, and a stretchability that allows it to deform when it is separated from the storage item 42 . It is preferable to have resiliency to return to its original shape and piercing strength to the extent that it does not break when the corners of the stored article 42 are pressed. The puncture strength is preferably 5N or more, more preferably 10N or more. Moreover, the antifreeze permeability of the antifreeze bag 52 is preferably 10 g/(m ² ·day) or less.

It is preferable that the stretchable thin film forming the antifreeze bag 52 is capable of realizing the above properties of the antifreeze bag 52 . Examples of materials for such a stretchable thin film include EVA (ethylene-vinyl acetate copolymer resin), polyisoprene rubber, and nylon. The antifreeze bag 52 may be such a stretchable thin film with a surface coating (for example, aluminum vapor deposition).

The antifreeze 19 inside the antifreeze bag 52 is preferably slurry or sherbet at the freezing temperature. The viscosity of the slurry-like or sherbet-like antifreeze 19 at the freezing temperature is preferably 15 Pa·s or more and 150 Pa·s or less, more preferably 50 Pa·s or more and 60 Pa·s or less.

Also, the antifreeze 19 is preferably a harmless substance that can be taken orally by humans. Examples of harmless substances that can be used as antifreeze 19 include ethanol-based food additives, propylene glycol-based food additives, aqueous sodium chloride solution, and vegetable oils. Also, the antifreeze liquid 19 is preferably colored. When the antifreeze 19 is colored, the color of the antifreeze 19 is preferably different from the color of the antifreeze bag 52 .

The antifreeze 19 preferably has two or more properties of being slurry or sherbet at freezing temperatures, being a harmless substance, and being colored, and having all three properties. is more preferred.

In the freezing apparatus 40 having the structure described above, the stored items 42 are sandwiched between the metal plate 51 on the first member 44 side and the antifreeze bag 52 on the second member 45 side.

As shown in FIG. 11, a space forming portion 84 is formed on the second member 45 at a location opposite to the hinge 46 (a location far from the hinge 46). A specific location where the space forming portion 84 is formed is, for example, a location above the center position of the second member 45 in the vertical direction. The space forming part 84 forms a space that serves as an escape for the antifreeze 19 when the antifreeze bag 52 is pushed due to the object 42 being sandwiched between the metal plate 51 and the antifreeze bag 52.例文帳に追加

The space forming portion 84 is formed as a recess when the second member 45 is viewed from the inside, and the space forming portion 84 is formed as a protrusion when the second member 45 is viewed from the outside. there is The space forming portion 84 as a concave portion is gradually deepened with distance from the hinge 46 . As a specific example, as shown in FIGS. 11 and 13, the space forming portion 84 is deepened in two steps, and consists of a shallow first step portion 85 and a deep second step portion 86 . The second stepped portion 86 is further away from the hinge 46 . As a preferable example, as shown in FIG. 11, the first stepped portion 85 is wider than the second stepped portion 86 in the vertical direction, and as shown in FIG. Large area when you see it.

Note that the space forming portion 84 may be divided into more steps (portions with different depths). Further, the depth of the space forming portion 84 may not be increased stepwise, but may be increased continuously with increasing distance from the hinge 46 by one inclined surface.

Due to the presence of such a space forming portion 84, an internal container space 87 is formed between the second member 45 and the antifreeze bag 52, as shown in FIG. The container internal space 87 is located behind the antifreeze bag 52 and widens stepwise as the distance from the hinge 46 increases. That is, the container internal space 87 is separated from a first container internal space 88 between the first stepped portion 85 and the antifreeze bag 52 and a second container internal space 89 between the second stepped portion 86 and the antifreeze bag 52. Become. The first container inner space 88 and the second container inner space 89 are continuous, and the second container inner space 89 is farther from the hinge 46 .

Here, since the first stepped portion 85 is shallow and the second stepped portion 86 is deep in the space forming portion 84 as described above, the first container internal space 88 is narrower in the front-rear direction than the second container internal space 87 . The container internal space 89 is wider in the front-rear direction. Further, when the first stepped portion 85 has a larger area than the second stepped portion 86 when viewed in the front-rear direction as described above, the first container inner space 88 is vertically wider than the second container inner space 89. , the area of the first container internal space 88 is larger than that of the second container internal space 89 when viewed from the front-rear direction.

As shown in FIG. 11, in this embodiment, the first member 44 is also formed with a space forming portion 67 composed of a shallow first stepped portion 63 and a deep second stepped portion 64, similar to the second member 45. ing. This space forming portion 67 is modified from the present embodiment so that the antifreeze bag 52 is accommodated in both the first member 44 and the second member 45, or the antifreeze bag 52 is accommodated in the first member 44 and the second member It can be used as an escape place for the antifreeze liquid 19 when storing the cooling agent 50 and the metal plate 51 in the 45 . When the antifreeze bag 52 is accommodated in the first member 44 , a space inside the container is formed in front of the antifreeze bag 52 .

Thus, in this embodiment, the first member 44 is also formed with the space forming portion 67, but the space forming portion 67 is not necessarily required if there is no possibility of accommodating the antifreeze bag 52 in the first member 44. . In that case, as shown in FIG. 17, the first member 44 may not have the space forming portion 67 and the front surface of the first member 44 may be flat.

Further, the hinge 46 has a structure in which the first member 44 and the second member 45 can be separated when the first member 44 and the second member 45 are opened by a predetermined angle (for example, a predetermined angle of 180° or more). is preferred. 18 to 20 show an example of the detailed structure of such a hinge 46. FIG.

The hinge 46 is formed by combining a first hinge member 90 provided at the lower end of the first fixing member 56 and a second hinge member 91 provided at the lower end of the second fixing member 58 . ing.

As shown in FIG. 18 , the first hinge member 90 has a circular portion 92 protruding downward from the lower end of the first fixing member 56 . The circular portion 92 has a substantially circular shape when viewed in the left-right direction (in the direction of the hinge axis), but is partially formed with a notch 93 formed by cutting out the circumference. Further, the first hinge member 90 has a shaft portion 94 extending from the circular portion 92 in one direction in the hinge axis direction.

Further, as shown in FIG. 19, the second hinge member 91 has a circular portion 95 protruding downward from the lower end portion of the second fixing member 58 . The circular portion 95 has a substantially circular shape when viewed in the left-right direction (hinge axis direction). A hole 96 is formed in the center of this circular portion 95 . Further, the second hinge member 91 includes an arm portion 97 extending from the circumferential surface of the circular portion 95 toward the other side of the hinge axial direction (the opposite direction to the direction in which the shaft portion 94 extends), and the tip of the arm portion 97. and a stop 98 provided on the . The stop portion 98 is aligned with the center hole 96 of the circular portion 95 in the hinge axis direction.

By inserting the shaft portion 94 of the first hinge member 90 into the hole 96 of the second hinge member 91, the first hinge member 90 and the second hinge member 91 are combined as shown in FIG. there is When the first hinge member 90 and the second hinge member 91 are combined, the circular portion 92 of the first hinge member 90 fits between the circular portion 95 and the stop portion 98 of the second hinge member 91. , thereby preventing the first hinge member 90 and the second hinge member 91 from coming off.

However, when the user opens the first member 44 and the second member 45 by a predetermined angle, the notch 93 of the circular portion 92 of the first hinge member 90 and the stop portion 98 of the second hinge member 91 move in the hinge axial direction. match. In this state, when the user shifts the first member 44 and the second member 45 in the other of the hinge axial directions (the direction opposite to the direction in which the shaft portion 94 extends from the circular portion 92), the second hinge member 91 The stop portion 98 passes through the notch 93 of the first hinge member 90 , and the shaft portion 94 of the first hinge member 90 is pulled out from the hole 96 of the second hinge member 91 . And thereby, the first member 44 and the second member 45 are separated.

With such a structure, the first member 44 and the second member 45 can be separated.

Looking at the outside of the freezing device 40, as shown in FIGS. 9 and 11, a hook 78 is provided on the upper portion of the outer surface of the first member 44. As shown in FIGS. Further, a recessed groove 79 recessed upward is formed in the lower portion of the first member 44 . The hook 78 is hooked to the upper end of the front wall 80 of the storage container 18 , and the protrusion 82 (see FIGS. 4 and 6 ) at the bottom of the storage container 18 is inserted into the concave groove 79 , so that the first member 44 is attached to the storage container 18 . Fixed. And thereby, the freezing device 40 is fixed to the front wall 80 of the container 18 .

However, the user can easily remove the freezing device 40 from the storage container 18 by removing the hook 78 from the front wall 80 of the storage container 18 and pulling the freezing device 40 upward.

Further, due to the structure as described above, the first member 44 holding the metal plate 51 remains fixed to the front wall 80 of the storage container 18, and the second member housing the antifreeze bag 52 is held. 45 can be tilted backward to open and close the outer shell container.

Further, the first member 44 and the second member 45 are provided with lock members for holding the outer shell container in a closed state. As shown in FIG. 11 , in this embodiment, as an example of the locking member, a hooking portion 43 is provided on the upper portion of the first member 44 and a hooking claw 41 is provided on the upper portion of the second member 45 . By hooking the hook 41 on the hooking portion 43, the upper portion of the first member 44 and the upper portion of the second member 45 are fixed to hold the outer shell container in a closed state. By manipulating the hooking claw 41, the user can lock and unlock the outer shell container so as to hold it in the closed state.

A large number of fins 59 are provided on the outer surfaces of the first member 44 and the second member 45 . As a result, the heat of the object 42 stored in the freezing device 40 is radiated from the fins 59 via the antifreeze liquid 19, and the cooling speed of the object 42 is increased.

The fins 59 on the outer surface of the second member 45 are provided not on the outer surface side of the space forming portion 84 but on the outer surface side below the space forming portion 84 as shown in FIGS. Therefore, as shown in FIG. 11, the fins 59 are outside the area where the second member 45 and the antifreeze bag 52 are always close to each other (the second member 45 and the antifreeze bag 52 are not in contact with each other). may be used). Similarly, the fins 59 on the outer surface of the first member 44 are also provided not on the outer surface side of the space forming portion 67 but on the outer surface side below the space forming portion 67 .

4. Method of Using the Freezing Apparatus First, it is assumed that the freezing apparatus 40 is stored in advance in the front storage area 83 of the storage container 18 of the freezer compartment 28 . Therefore, the antifreeze liquid 19 is lowered to the freezing temperature or its vicinity. At this time, the first member 44 of the freezing device 40 is fixed to the front wall 80 of the container 18 .

When the user pulls the freezer compartment door 29 forward to open the freezer compartment 28 , the freezer 40 can be visually recognized from the outside of the freezer compartment 28 . Since the freezing device 40 is provided along the front wall 80 of the storage container 18 (strictly speaking, the front protruding wall portion 81 which is a part of the front wall 80), the user only needs to pull the freezer compartment door 29 slightly. The freezing device 40 can be visually recognized, and the operation for storing the object 42 in the freezing device 40 can be started.

Two examples will be introduced as a method of storing the storage object 42 in the freezing device 40. FIG. As a first example of the storage method, first, the user hooks the hook 41 of the freezing device 40 while the first member 44 of the freezing device 40 is fixed to the front wall 80 of the storage container 18 . The second member 45 is removed from the stop portion 43, moved backward, and knocked down to open the outer shell container. FIG. 21 shows how the second member 45 is tilted backward to open the outer shell container. Next, the user places the container 42 between the metal plate 51 on the first member 44 side and the antifreeze bag 52 on the second member 45 side. Next, the user moves the second member 45 forward to close the outer shell container, and hooks the hook 41 on the hook portion 43 to lock it.

As a second example of the storage method, first, the user removes the freezing device 40 from the front wall 80 of the storage container 18 and takes it out of the storage. Next, the user opens the outer shell container, puts the contents 42 between the metal plate 51 and the antifreeze bag 52, and then closes and locks the outer shell container. . The user then replaces the freezing device 40 to its original location in the container 18 .

When the object 42 is placed between the metal plate 51 of the freezing device 40 and the antifreeze bag 52 as in these two examples, the antifreeze bag 52 is deformed so as to follow the shape of the object 42 . close to the rear part of the Note that "close contact" includes not only a state in which no air exists between the stored item 42 and the antifreeze bag 52, but also a state in which some air exists between the stored item 42 and the antifreeze bag 52.

When the stored material 42 enters between the metal plate 51 of the freezing device 40 and the antifreeze bag 52, as shown in FIGS. and opposite direction) and enters the container inner space 87 in the outer shell container. That is, the antifreeze bag 52 deforms and expands toward the container internal space 87 .

When the stored item 42 has a general size, as shown in FIG. get into However, when the stored item 42 is large, as shown in FIG. 23, the antifreeze liquid 19 pushed by the stored item 42 is not only in the first container inner space 88 but also in the second container above it (the side farther from the hinge 46). It even enters the inner space 89 .

If the object 42 is larger than the metal plate 51 and the antifreeze bag 52, and if the object 42 is placed between the metal plate 51 and the antifreeze bag 52, the outer shell container cannot be closed. 45 are opened by a predetermined angle to separate the first member 44 and the second member 45 . Then, the user puts the storage object 42 between the separated first member 44 and second member 45 . As a result, the metal plate 51 comes into contact with the front portion of the stored item 42 , and the antifreeze bag 52 is in close contact with the rear portion of the stored item 42 . The user may bundle the first member 44, the stored article 42 and the second member 45 together with a binding band or the like when the stored article 42 is sandwiched between the separated first member 44 and the second member 45. FIG.

The user closes the freezer compartment 28 after storing the contents 42 in the freezer 40 . The contents 42 are frozen inside the closed freezer compartment 28 .

Specifically, in the freezing device 40, the antifreeze bag 52 is deformed so as to follow the shape of the stored item 42 and is in close contact with the rear portion of the stored item 42. It is surrounded by the antifreeze liquid 19 through. As a result, heat is exchanged with the antifreeze liquid 19 in the rear portion of the stored item 42, and the stored item 42 is rapidly cooled. Of course, heat exchange is also performed between the stored object 42 and the metal plate 51 . When cooled in this manner, the contents 42 cool faster than if the contents 42 were placed directly into the freezer compartment 28 without the freezing device 40 being used.

Thereafter, after a certain amount of time has passed since the stored item 42 was sandwiched between the metal plate 51 and the antifreeze bag 52 , the temperature of the stored item 42 drops to the same level as that of the antifreeze liquid 19 . The stored object 42 is frozen until it reaches a temperature equivalent to that of the antifreeze liquid 19.例文帳に追加As described above, in the present embodiment, the cooling speed of the stored items 42 is high, so the time required for the stored items 42 to freeze is also short.

When the stored item 42 is to be taken out from the freezing device 40, the user opens the outer shell container and takes out the stored item 42 in the same manner as when it was stored. When the user removes the contents 42 from the freezer 40, the antifreeze bag 52 recovers its original shape. In this manner, the antifreeze bag 52 can repeat deformation and recovery each time the user puts in and takes out the storage item 42 .

The user can also carry the freezing device 40 in which the stored items 42 are stored outside the refrigerator or leave it outside the refrigerator.

5. Effects of the Embodiment In the refrigerator 10 of the present embodiment, the freezing device 40 as a container is provided along the front wall 80 of the storage container 18, so that the space near the freezer compartment door 29 is effectively utilized. .

In this embodiment, a recess 74 is formed inside the freezer compartment door 29, and the front storage area 83 of the storage container 18 enters the recess 74, and the front storage area 83 serves as a storage tool. At least a portion of device 40 is positioned. Therefore, the recess 74 inside the freezer compartment door 29 is effectively utilized.

In addition, in this embodiment, since the front storage area 83 is provided under the downward inclined surface 76 of the protrusion 72 on the inner side of the freezer compartment door 29, the cold air flowing from the rear to the front in the freezer compartment 28 is provided. , hits the downward inclined surface 76 of the projection 72 and flows into the front storage area 83 . Therefore, the freezing device 40 as a storage device arranged in the front storage area 83 is rapidly cooled.

Further, in this embodiment, the first member 44 and the second member 45 are provided so as to be openable and closable, and the first member 44 is fixed to the front wall 80 of the storage container 18 . Therefore, while the first member 44 remains fixed to the front wall 80 of the storage container 18, the user can tilt the second member 45 backward to open and close the outer shell container.

Here, since the hook 78 is used to fix the first member 44 to the front wall 80 of the storage container 18 , the user can easily remove the freezing device 40 from the front wall 80 of the storage container 18 . Since the freezing device 40 can be easily detached, the user can take the freezing device 40 out of the freezer when storing the storage items 42 in the freezing device 40 to carry out the storage work. Also, the user can leave the freezing device 40 on a table or the like or carry it around.

Further, in this embodiment, since the first member 44 and the second member 45 are connected by the hinge 46, the first member 44 and the second member 45 can be easily opened and closed. Further, since this hinge 46 can be separated when it is opened at a predetermined angle, when the storage object 42 is large, the first member 44 and the second member 45 can be separated, and the first member 44 and the second member 45 can be separated. It is possible to use a method of sandwiching the stored article 42 between the two.

Further, in this embodiment, the freezing device 40 is used as a container, and the stored material 42 is sandwiched between the antifreeze bag 52 and the metal plate 51 . Therefore, heat is exchanged between the stored item 42 and the antifreeze liquid 19 in the antifreeze bag 52, and the stored item 42 is rapidly cooled and frozen in a short time. Also, heat is exchanged between the stored object 42 and the metal plate 51, but since the cold storage agent 50 is arranged on the back side (front) of the metal plate 51, the heat of the stored object 42 is transferred to the metal plate 51. A large amount is also taken from 51, and the stored article 42 is rapidly cooled.

Here, if the antifreeze bag 52 is made of a stretchable thin film having high stretchability, the antifreeze bag 52 can be brought into close contact with the stored object 42, so that the stored object 42 can be cooled efficiently. In addition, if the antifreeze bag 52 is made of a stretchable thin film with high recovery, the antifreeze bag 52 can be used many times. Also, if the antifreeze bag 52 is made of an elastic thin film having a high puncture strength and the puncture strength is, for example, 5N or more or 10N or more, the antifreeze bag 52 is hard to break even if the stored object 42 has corners.

Further, if the antifreeze liquid 19 in the antifreeze liquid bag 52 is slurry-like or sherbet-like at the freezing temperature, heat exchange between the antifreeze liquid 19 and the stored material 42 is facilitated. In particular, if the slurry-like or sherbet-like antifreeze liquid 19 has a viscosity at the freezing temperature of 15 Pa·s or more and 150 Pa·s or less, the heat exchange is further promoted, and if it is 50 Pa·s or more and 60 Pa·s or less, the heat exchange is further promoted. be done.

Further, in this embodiment, since the container internal space 87 is formed between the antifreeze bag 52 and the second member 45 , when the storage object 42 is stored in the freezing device 40 , the storage object 42 pushes the storage object 42 . The antifreeze 19 in the antifreeze bag 52 can escape to the container internal space 87 . Here, since the container internal space 87 is formed in the second member 45 on the opposite side of the hinge 46, the antifreeze liquid 19 gradually flows into the container as the first member 44 and the second member 45 are closed. It can escape to the inner space 87 .

In addition, since the container inner space 87 is formed above the second member 45 (that is, in the direction opposite to the direction in which gravity is applied), the antifreeze bag 52 is pushed by the stored material 42 and high pressure is applied to the antifreeze 19 . The antifreeze liquid 19 escapes to the container internal space 87 for the first time. As the antifreeze 19 escapes to the container internal space 87, the high pressure applied to the antifreeze 19 is released. Therefore, the pressure applied to the antifreeze liquid 19 is kept constant, and the pressure applied to the stored items 42 is also kept constant. Further, the container inner space 87 is formed in the upper part of the second member 45, and the antifreeze solution 19 escapes into the container inner space 87 only when the antifreeze bag 52 is pushed by the stored item 42. Therefore, the stored item 42 is stored. It is possible to prevent the antifreeze bag 52 from being deformed by gravity when it is absent.

Here, as described above, the width of the container inner space 87 in the front-rear direction widens as it moves away from the hinge 46, and widens as it moves upward (that is, in the direction opposite to the direction in which gravity is applied). Therefore, deformation of the antifreeze bag 52 can be minimized when the stored item 42 is small compared to when the container inner space 87 is wide in the front-rear direction.

Further, as described above, the width of the container inner space 87 in the front-rear direction widens step by step, and the first container inner space 88 below the container inner space 87 and the second container inner space above the container inner space 87 are formed. 89 are formed. The first container internal space 88 is narrow in the front-rear direction, and the second container internal space 89 is wide in the front-rear direction.

Therefore, when a relatively small storage object 42 is stored, the antifreeze liquid 19 pushed by the storage object 42 escapes only to the first container internal space 88 which is narrow in the front-rear direction. As a result, the antifreeze bag 52 is not greatly deformed, and a certain amount of pressure is applied from the antifreeze 19 to the stored item 42 , so that the antifreeze bag 52 can adhere to the stored item 42 . Also, when a relatively large storage object 42 is stored, the first container internal space 88 alone is not enough for the antifreeze liquid 19 pushed by the storage object 42 to escape, but there is a second container internal space 89 that is wide in the front-rear direction. Therefore, a sufficiently large amount of the antifreeze liquid 19 can be released into the second container internal space 89 .

Here, the area of the first container internal space 88, which is narrow in the front-rear direction, is larger than the area of the second container internal space 89, which is wide in the front-rear direction, when viewed from the front-rear direction. Therefore, normally, the antifreeze 19 is released only into the first container internal space 88 so that the stored object 42 is under high pressure, and the antifreeze 19 is released only when the stored object 42 is larger than usual and the first container internal space 88 cannot cope with it. can be escaped to the second container internal space 89 .

Further, as described above, the freezing device 40 has the first member 44 provided with the cold storage agent 50 and the metal plate 51 on the front side (that is, the freezer compartment door 29 side) and the second member 45 containing the antifreeze bag 52 on the front side. It is arranged so as to be on the rear side (that is, inside the chamber). Therefore, the space forming portion 84 of the second member 45 for forming the container inner space 87 is a convex portion that protrudes toward the inner side of the refrigerator rather than toward the freezer compartment door 29 side. Therefore, objects can be stored below the space forming portion 84 protruding rearward, and the space below the space forming portion 84 is not wasted.

In addition, since the fins 59 on the outer surface of the second member 45 are provided below the space forming portion 84 and outside the area where the second member 45 and the antifreeze bag 52 are always close to each other, the heat of the antifreeze 19 is is easy to dissipate heat. In addition, since there is no fin 59 outside the space forming portion 84 projecting in the front-rear direction, the freezing device 40 is compact.

6. Modification A modification of the above embodiment will be described. Any one of the plurality of modifications described below may be applied to the above embodiment, or any two or more of the modifications described below may be applied in combination. good. Moreover, various modifications other than the following modifications are possible. In addition, in the diagrams showing the modified examples, the same reference numerals as in the above-described embodiment are assigned to the same components as in the above-described embodiment.

(1) Modification 1
A storage device such as the freezing device 40 may be provided along the front wall 80 of the storage container 18 and may not necessarily be provided inside the storage container 18 as in the above embodiment.

For example, as shown in FIG. 24, a gap wider than the thickness of the freezer 40 may be formed between the front wall 80 of the storage container 18 and the freezer compartment door 29, and the freezer 40 may be provided in the gap. . In that case, the freezing device 40 may be fixed to the front wall 80 of the storage container 18 or the inside surface of the freezer compartment door 29 with a member such as the hook 78 in the above embodiment.

(2) Modification 2
The shape of the storage container 18 is not limited to that of the above embodiment. For example, in the above-described embodiment, the front wall 80 of the storage container 18 is formed with the forward protruding wall portion 81, but the front wall is not formed with such a forward protruding wall portion, and the entire front wall of the storage container is It may be in the shape of a single flat plate. It suffices if a storage tool is provided along such a front wall.

(3) Modification 3
The freezing device may be any device that rapidly cools and freezes the stored object 42 using the antifreeze liquid 19, and its specific structure is not limited to the structure of the above embodiment.

For example, a freezing apparatus may be used in which the antifreeze bags 52 are accommodated in both the first member 44 and the second member 45 in the above embodiment, and the stored items 42 are sandwiched between the antifreeze bags 52 on both the front and rear sides.

In the above embodiment, the first member 44 provided with the cold storage agent 50 and the metal plate 51 is on the front side (that is, the freezer compartment door 29 side), and the second member 45 that accommodates the antifreeze bag 52 is on the rear side (that is, inside of the refrigerator), but it may be the other way around. That is, the first member 44 provided with the cold storage agent 50 and the metal plate 51 may be on the rear side, and the second member 45 containing the antifreeze bag 52 may be on the front side.

(4) Modification 4
In the above embodiment, the hinge 46 that connects the first member 44 and the second member 45 in an openable/closable manner was provided at the bottom of the outer shell container, but the location of the hinge is not limited to the bottom. For example, a hinge may be provided on either the left or right portion of the outer shell container, and the first member and the second member can be opened and closed on the opposite side.

In the case where a hinge connecting the first member and the second member in an openable/closable manner is provided in a portion other than the lower portion of the outer shell container, and the antifreeze bag is accommodated in at least one of the first member and the second member, the above-described A space forming portion similar to the space forming portion 84 of the embodiment is preferably formed at a location in the front-rear direction of the antifreeze bag.

Two locations are conceivable as the location of the space forming portion in such a case. The first location is the location on the opposite side of the hinge from the outer shell container (the location farther from the hinge). For example, if the hinge is provided at the left end of the outer shell, the space forming portion is formed at the right side of the outer shell. In this case, it is preferable that the width of the space forming portion in the front-rear direction increases with distance from the hinge, and it is more preferable that the width increases stepwise as in the above embodiment. In addition, when the width of the space forming portion in the front-rear direction is gradually increased, the area of the space-forming portion that is narrower in the front-rear direction is larger than the area that is wider in the front-rear direction when viewed from the front-rear direction. Wide is preferred.

Since the space forming part is located far from the hinge, the antifreeze liquid gradually escapes into the space forming part as the first member and the second member are closed.

The second location is the upper (ie, opposite direction of gravity) location in the outer shell container. For example, a hinge is provided at the left end of the outer shell and a space forming portion is formed at a location above the outer shell. In this case, it is preferable that the width of the space forming portion in the front-rear direction increases upward, and it is more preferable that the width increases stepwise as in the above embodiment. In addition, when the width of the space forming portion in the front-rear direction is gradually increased, the area of the space-forming portion that is narrower in the front-rear direction is larger than the area that is wider in the front-rear direction when viewed from the front-rear direction. Wide is preferred.

Since the space forming part is located above the outer shell container, the antifreeze bag can be prevented from being deformed by gravity, and the deformation of the antifreeze bag can be minimized.

Also, the first member and the second member may be connected by a connecting portion other than a hinge.

(5) Modification 5
In a case where a freezing device as a storage device has a first member and a second member that can be opened and closed, and an antifreeze bag filled with antifreeze liquid is stored in at least one of the first member and the second member, the antifreeze liquid A pressing mechanism for pressing the bag may be provided. An example of a freezing apparatus provided with a pressing mechanism will be described with reference to FIGS. 25 and 26. FIG.

In the freezing device 140 of this modified example, the cold storage agent 50 and the metal plate 151 are held in the front first member 144, and the antifreeze bag 52 is accommodated in the rear second member 145, as in the above-described embodiment. do. However, the first member 144 may contain the antifreeze bag 52 instead of the cold storage agent 50 and the metal plate 151 .

The second member 145 has a thickness in the front-rear direction, and the antifreeze bag 52 is accommodated in the front region inside the second member 145 . A plate member 148 movable in the front-rear direction is in close contact with the rear surface of the antifreeze bag 52 . A pushing mechanism for pushing the antifreeze bag 52 forward by pushing the plate-like member 148 forward is housed in the rear region of the second member 145 .

The pressing mechanism has, as a part thereof, a rack and pinion consisting of a rack 101 which is a toothed plate-shaped member extending left and right, and a first gear 102 which meshes with the teeth of the rack 101 . The rack 101 is integrated with a slide bar 103 that can slide in the horizontal direction. As shown in FIGS. 25 and 26, the rear portion of the second member 145 is formed with a window 104 which leads to the outside. It's becoming

The first gear 102 is a gear that rotates around a vertical rotation axis, and meshes with a second gear 105 that rotates around a horizontal rotation axis. A pressing rod 106 is fixed to the second gear 105 as a pressing member extending in the circumferential direction of the second gear 105 (downward as shown in the drawing as a more specific example). The tip of the pressing rod 106 is in contact with the plate member 148 .

When the user slides the slide bar 103 left and right, the rack 101 moves together with the slide bar 103, the first gear 102 meshing with the rack 101 rotates, and the second gear 105 meshing with the first gear 102 rotates. It rotates and the tip of the pressing rod 106 moves back and forth. As a result, the pressing rod 106 pushes the plate-like member 148 forward or separates from the plate-like member 148 . When the pressing rod 106 pushes the plate member 148 forward, the antifreeze bag 52 is pushed forward by the plate member 148 .

Due to this structure, the user can press the antifreeze bag 52 forward by operating the slide bar 103 after storing the storage item 42 in the freezing device 140 to bring the antifreeze bag 52 into close contact with the storage item 42 . can.

In the second member 145, an escape space for the antifreeze liquid 19 may be provided like the container internal space 87 in the above embodiment. For example, a portion of the plate member 148 may be deformed to have the same shape as the space forming portion 84 in the above embodiment.

Alternatively, the pressing rod 106 may directly press the antifreeze bag 52 without the plate member 148 interposed therebetween.

(6) Modification 6
Another example of a freezing device provided with a pressing mechanism will be described with reference to FIGS. 27 and 28. FIG.

In the freezing apparatus 240 of this modified example, the cold storage agent 50 and the metal plate 251 are held in the front first member 244, and the antifreeze bag 52 is accommodated in the rear second member 245, as in the above-described embodiment. do. However, the first member 244 may contain the antifreeze bag 52 instead of the cold storage agent 50 and the metal plate 251 .

The second member 245 has a thickness in the front-rear direction, and the antifreeze bag 52 is accommodated in the front region inside the second member 245 . A plate member 248 movable in the front-rear direction is in close contact with the rear surface of the antifreeze bag 52 . A pushing mechanism for pushing the antifreeze bag 52 forward by pushing the plate member 248 forward is housed in the rear area of the second member 245 .

The pressing mechanism has, as a part thereof, a ratchet consisting of a gear 205 that rotates around a rotation axis in the horizontal direction and a pawl 201 that stops the rotation of the gear 205 . In this ratchet, the gear 205 can only rotate in one direction (forward direction), and rotation in the opposite direction is blocked by the pawl 201 meshing with the gear 205 . However, when a release button 203, which will be described later, is pressed, the pawl 201 is disengaged from the gear 205, allowing the gear 205 to rotate in the opposite direction.

A pressing member 206 is fixed to the gear 205 and extends in the circumferential direction of the gear 205 (as a more specific example, downward as shown). The tip of the pressing member 206 is in contact with the plate member 248 .
