It is designed to be pulled out while positioned on the rear side of the portion 26h. A second container 26 covers the accommodation space of the first container 24 .

Further, when the second container 26 is pushed back to open the first container 24 after being pulled out, the third container 28 is held by the second container 26 by the hill-shaped hook portion (described above) of the second container 26 . configured to move with

In this embodiment, even when the large freezer compartment 18 is closed (the door 18d is closed), that is, even when the first to third containers are located on the farthest side, the handle of the second container 26 is The portion 26h is located on the rear side of the handle portion 24h of the first container 24 (moreover, on the rear side of the handle portion 18h of the door 18d), and the handle portion 28h of the third container 28 is located on the handle portion 26h of the second container 26. It is in a state of being located on the rear side. Moreover, when the large freezer compartment 18 is closed, the hooking portion of the lower container is positioned rearward from the hooked portion of the upper container.

The first container 24 is a deep, substantially rectangular parallelepiped container with an open top (see FIG. 4). The first container 24 includes a first side portion 24w (see FIGS. 4 and 6) that defines the inner space of the first container 24, and a first side portion 24w that slidably supports the second container 26. and a support portion 24s (see FIG. 6). The first support portion 24s is continuous with the upper end portions of the left side and the right side of the first side portion 24w when viewed from the front side of the refrigerator and protrudes outward from the container.

The first support portion 24s includes a first support plate portion 24sg that protrudes outward in the width direction of the first container 24 from the first side portion 24w in a flange shape and has a top surface that serves as a sliding surface, and a first support plate portion 24sg. and a regulating plate portion 24se that extends upward from the container width direction outer end of the second container 26 to regulate the movement of the second container 26 to the width direction outside.

The second container 26 is a shallow rectangular parallelepiped container with an open upper surface (see FIGS. 4 and 5). The second container 26 includes a second side portion 26w (see FIG. 6) forming the inner space of the second container 26, and second support portions 26s (see FIG. 6) and a rail member 26r (see FIGS. 5 and 6) that is locked onto the second support portion 26s.

The second supporting portion 26s includes a second supported plate portion 26sa that protrudes outward in the width direction of the second container 26 from the second side portion 26w in a flange shape and has a lower surface that serves as a sliding surface, and a second supported plate portion 26sa. an upper plate portion 26su projecting from the second side portion 26w to the outside in the width direction of the second container 26 at a position slightly above the portion 26sa and having a locking hole H for locking the rail member 26r; , have

The rail member 26r is composed of a rail body 26rm having a substantially U-shaped cross section along the width direction (horizontally directed square pipe shape without an upper portion), and a rail body 26rm extending downward from the bottom surface of the rail body 26rm. and a locking protrusion P that protrudes and is inserted into the locking hole H. A slidable rail surface RS is formed on the rail body 26rm.

The third container 28 is a shallow rectangular parallelepiped container with an open top (see FIG. 4). The third container 28 is provided on a third side portion 28w (see FIG. 6) forming an inner space of the third container 28 and on upper portions of left and right ends of the third side portion 28w, and slides on the rail surface RS. and a possible supported portion 28s (see FIG. 6).

The lower end surface of the protruding portion 28p is a sliding surface, and when the third container 28 is placed on the second container 26, the lower end portion of the protruding portion 28p contacts the rail surface RS and is slidable. there is In addition, the rail body 26rm is substantially U-shaped in cross section along the short direction of the rail member 26r, thereby preventing the projecting portion 28p from coming off the rail member 26r in the left-right direction.

With such a configuration, when the first container 24 is pulled out, the hill-shaped hooking portion of the first container 24 contacts the hooked portion of the second container 26 from the rear side, and the second container 26 is also interlocked. is pulled out. Moreover, when the second container 26 is pulled out, the hill-shaped hooking portion of the second container 26 abuts the hooked portion of the third container 28 from the rear side, and the third container 28 is also pulled out in conjunction. .

After the first to third containers are pulled out in this way, the user puts his/her hand on the second container 26 and pushes it back so that the hooked portion of the second container 26 overcomes the hooking portion of the first container. The force (specifically, the force of the user fixing the door 18d with one hand to fix the first container 24 so that it does not move and pushing the second container 26 backward with the other hand) is applied to the second container. When given to the container 26, the second container 26 moves to the back side. At that time, the third container 28 moves to the back side together with the second container 26 .

Also, after the first to third containers have been pulled out, the user can place his or her hand on the third container 28 instead of the second container 26 so that the hooked portion of the third container 28 is hooked on the second container 26. (Specifically, a force for the user to fix the second container 26 with one hand so that it does not move and push the third container 28 rearward with the other hand to move it) is applied to the third container. 28, the third container 28 moves to the back side.

<Airflow in the large freezer compartment>
A structure for generating an airflow in the large freezer compartment will be described below with reference to FIGS. 7 and 8. FIG.

The first container 24, the second container 26, and the third container 28 are formed with holes 24a1, 26a1, and 28a1, respectively, through which cool air passes.

The positions of the holes are different from each other in the storage containers 22 that are adjacent to each other in the vertical direction. When the large freezer compartment 18 is closed, the hole 26a1 of the second container 26 is located forward of the hole 24a1 of the first container 24 adjacent on the upper side, and the hole 28a1 of the third container 28 is It is located behind the hole 26a1 of the second container 26 adjacent to the upper side.

In this embodiment, the holes 24a1, 26a1, and 28a1 are all arranged at the bottom of the container. The holes 24a1 are arranged on the left and right sides of the first side portion 24w when viewed from the front side of the refrigerator, and the holes 26a1 and 28a1 are located on the container side portions (left and right sides when viewed from the front side of the refrigerator). from the side of the container) to the bottom of the container, a plurality of slits are arranged in parallel with each other (for example, in the second container 26, as shown in FIG. 26b). The hole 24a1 and the hole 28a1 are at the same position in the front-rear direction.

The air circulation path C of the refrigerator main body 10 is formed with a first circulation path opening C<b>1 and a second circulation path opening C<b>2 for allowing cold air to flow into the large freezer compartment 18 .

The circulation path first opening C<b>1 is arranged on the rear side of the first container 24 . Further, the first container 24 is provided with the following structure so that the cool air that flows out from the circulation path first opening C1 when the large freezer compartment 18 is closed can flow into the first container 24 as it is without changing the flow direction. A rear opening 24j is positioned and arranged on the rear side of the container (see the airflow F1 shown in FIG. 7). That is, when viewed from the front side of the refrigerator, the rear opening 24j is formed at a position overlapping the first circulation path opening C1 or at a position where the first circulation path opening C1 is arranged in the inner region.

The circulation path second opening C<b>2 is arranged on the rear side of the third container 28 . In addition, the third container 28 is provided with the following structure so that the cool air that flows out from the second opening C2 of the circulation path when the large freezer compartment 18 is closed can flow directly into the third container 28 without changing the direction of flow. A rear opening 28j is positioned and arranged on the rear side of the container (see air flow F3 shown in FIG. 7). Viewed from the front of the refrigerator. The rear opening 28j is formed at a position overlapping the circulation path second opening C2 or at a position where the circulation path second opening C2 is arranged in the inner region.

Here, no circulation path opening for discharging cold air from the air circulation path C is formed on the rear side of the second container 26 . Therefore, such cold air does not flow from the rear side of the second container 26 .

In addition, as shown in FIG. 8, a container bottom portion 26b of the second container 26 is formed with a second hole 26a2. The second holes 26a2 are formed by arranging a large number of openings (which may be mesh-like). In this embodiment, the second holes 26a2 are arranged in front of the holes 26a1. The total opening area of the second holes 26a2 is larger than the total opening area of the holes 26a1. A container bottom portion 28b of the third container 28 is similarly formed with a second hole 28a2. In addition, the hole 26a1 is larger in size per hole than the hole 26a1 and the second hole 26a2. Among the holes 28a1 and the second holes 28a2, the hole 28a1 is larger in size per hole.

(action, effect)
In this embodiment, the containers that are vertically adjacent to each other in the storage container 22, i.e., the first container 24 and the second container 26, and the second container 26 and the third container 28, have holes for cold air to pass through. are different from each other. Therefore, cold air from the first container 24 is prevented from flowing into the third container 28 without causing convection in the accommodation space of the second container 26 . Therefore, it is sufficiently avoided that the cold air temperature is lowered in order to lower the temperature inside the second container 26 and the food is frost-burned in the first container 24 or the second container 26 .

In addition, when the large freezer compartment 18 is closed, the hole 26a1 of the second container 26 adjacent to the lower side is located forward of the hole 28a1 formed in the third container 28 . As a result, the cool air that has flowed into the third container 28 flows into the second container 26 through the holes 28a1, flows forward in the second container 26, and flows into the first container 24 through the holes 26a1. available (see airflow F3 shown in FIG. 7).

The holes 26a1 and 28a1 are formed extending from the side of the container to the bottom of the container. As a result, the degree of freedom in the direction of punching increases when punching for hole formation, and the punching work can be easily performed.

In the first to third containers, the holes 24a1, 26a1, and 28a1 are arranged on the side of the container, respectively. In the second container 26, the second hole 26a2 is arranged in the bottom of the container. is arranged at the bottom of the container, cold air can flow downward from both the sides of the container and the bottom of the container.

Since the first container 24 is the lowest container of the storage container 22, such a second hole is not formed in the container bottom portion of the first container 24. As shown in FIG. Therefore, the cool air that has flowed into the first container 24 can be efficiently used in the first container 24 . In addition, since the first container 24 does not extend over the hole 24a1 at the bottom of the container, cold air is more likely to stay in the container than in the second container 26 and the third container 28 .

Further, the first container 24 has a container rear side so that the cool air flowing out from the circulation path first opening C1 can flow into the first container 24 without changing its direction when the large freezer compartment 18 is closed. A rear opening 24j is arranged in position adjustment. Further, the third container 28 is provided with a container rear side so that the cool air flowing out from the circulation path second opening C2 can flow into the third container 28 without changing its direction when the large freezer compartment 18 is closed. A rear opening 28j is arranged in position adjustment. Therefore, cold air can be efficiently introduced into the first container 24 and the third container 28 .

A circulation path opening for discharging cold air from the air circulation path C is not formed on the rear side of the second container 26 . Therefore, since such cold air does not flow in from the rear side of the second container 26, indirect cooling is performed in the second container 26. It can be cooled by cold air via the third container 28 . As a result, it is possible to prevent the temperature of the stored food such as food from dropping too low.

Also, since the storage container 22 is arranged in the freezer compartment, even if the liquid from the food leaks into the second container 26 or the third container 28, the liquid is frozen. This effectively prevents the liquid from dripping downward from the second hole 26a2 formed in the container bottom 26b.

Further, when the handle portion 18h of the door 18d is pulled out, the handle portion 26h of the second container 26 is positioned on the rear side of the handle portion of the first container 24, and the handle portion 28h of the third container 28 is positioned. is located on the rear side of the handle portion 26h of the second container 26 when it is pulled out. As a result, when the user opens the large freezer compartment 18 by holding the door 18d, the second container 26 makes it difficult for cold air in the first container 24 to escape. Further, it is easy to adopt a configuration in which the third container 28 is moved together with the movement of the second container 26 .

Further, when the second container 26 is pushed back to open the first container 24 after being pulled out, the third container 28 moves together with the second container 26 . This allows the user to push back the second container 26 to open the first container 24 without pushing back the third container 28 .

Further, in the present embodiment, when the handle portion 18h of the door 18d is pulled out by hand, the second container 26 covers the accommodation space of the first container 24, and the second container 24 is opened in order to open the first container 24. When the container 26 is moved, the third container 28 is also moved together. As a result, when the first container 24 is pulled out, the sealing property of the first container 24 can be improved, and furthermore, by moving (pushing back) the second container 26, the third container 28 is also pushed back and the first container 24 is closed. 24 can be opened, which is convenient. In addition, in this specification, the airtightness means that the inflow and outflow of air (cold air) can be suppressed.

Even if the door 18d is pulled out, when the third container 28 is in the closed position, that is, when the large freezer compartment 18 is closed and the door 18d is in contact with the opening 10f, the third When the container 28 is positioned, the space on the rear side of the first to third containers in the large freezer compartment 18 is a closed space (inside air circulates for cold air circulation, and outside air circulates). It may be set as a space that is rarely entered/exited directly. As a result, even when the first container 24 is pulled out, cold air can be prevented from escaping from the closed space. In order for the space behind the first to third containers to become a closed space, for example, the rear ends of the first container 24 and the second container 26 do not protrude forward from the opening 10f. be.

Also, the material of the rail member 26r may be a material different from that of the first to third containers. As a result, it is possible to effectively suppress the occurrence of scratches when members made of the same material slide against each other. For example, if the rail member 26r is made of a slippery material such as Durapon, this effect becomes even more pronounced.

Further, when the door 18d of the large freezer compartment 18 is forcefully pulled out to forcefully pull out the first container 24, the third container 28 is prevented from jumping out forcefully in the pull-out direction (front side). A stopper 26rs (see FIG. 5) may be arranged on the rail member 26r of the container 26 .

The stopper 26rs is arranged on the front side of the hill-shaped hook portion of the second container 26 . For example, the stopper 26rs protrudes into the rail from the bottom surface or side wall of the front end portion of the rail member 26r, and when the first container 24 is vigorously pulled out, the projecting portion 28p of the third container 28 hits the stopper 26rs. It has a shape that prevents the protruding part 28p from getting over even if it comes in contact with it (for example, a shape that the protruding part 28p does not get over by protruding perpendicularly to the bottom surface or the side wall). Furthermore, by arranging such a stopper on the first container 24 as well, it is possible to prevent the second container 26 from popping out in the pull-out direction (front side).

Moreover, the left-right direction side (both sides) of the second container front portion 26k (see FIG. 5) extending in the left-right direction and formed with the handle portion 26h of the second container 26, Holes for air flow (for passing air) may be formed on the lateral direction sides (both sides) of the third container front portion 28k (see FIG. 4) where the handle portion 28h of the third container 28 is formed. . This makes it possible to effectively utilize the airflow around the handle portion exposed from the accommodation spaces of the second container 26 and the third container 28 .

The holes may be formed over the entire surface of the second container front portion 26k and the third container front portion 28k so that the second container front portion 26k and the third container front portion 28k are meshed. In this case, the dimensions of the holes may be the same as those of the second holes 26a2 and 28a2 (see FIGS. 7 and 8).

Further, the holes may be arranged in a row in the container width direction (horizontal direction) in the second container front portion 26k and the third container front portion 28k. In this case, since the number of holes is smaller than when they are formed over the entire surface, the holes have an inner diameter two to three times that of the second holes 26a2 and 28a2 in order to effectively pass the air. may

(Second embodiment)
Next, a second embodiment will be described. FIG. 9 is a side cross-sectional view showing the essential parts of the refrigerator according to the present embodiment when the large freezer compartment is pulled out.

In this embodiment, when the second container 26 is pulled out (for example, when the first container 24 and the second container 26 are pulled out by pulling out the door 18d), the third container 28 is pulled out as compared to the first embodiment. It is pulled out while opening the second container 26 without moving together with the second container 26 . Here, "pulled out while opening the second container 26" means that the third container when pulled out is designed so that the user can put his hand into the second container 26 from above when pulled out. 28 is smaller than the movement of the second container 26 .

In this embodiment, when the second container 26 is pulled out, the gently hill-shaped hooking portion (described above) for hooking and moving the third container 28 is formed at the rear portion of the rail surface RS. , the frictional force between the rail surface RS and the projecting portion 28p of the third container 28 is sufficiently low. Therefore, the third container 28 does not move together with the second container 26 at the start of withdrawal. Then, when the second container 26 is pulled out to the drawable end (draw-out complete position), the handle portion 28h of the third container 28 is pushed to the door of the storage compartment adjacent to the upper side of the large freezer compartment 18 (the door of the ice making compartment 14). 14d and the door 16d) of the small freezer compartment 16, the placement position of the gently hill-shaped hook is adjusted in advance.

As an example of this adjustment, when the door 18d is not pulled out, the hooking portion and the hooked portion are not in contact, and when the second container 26 is slightly pulled out, the hooking portion and the hooked portion come into contact. The arrangement positions of the hooking portion and the hooked portion are adjusted so that the third container 28 comes in contact with the second container 26 and moves forward in conjunction with the movement of the second container 26 . More specifically, when the door 18d is closed (not pulled out), the hooking portion and the hooked portion are separated in the front-rear direction. The distance from the position when the door is not pulled out to the position where the handle portion 28h is located on the front side of the door 14d (that is, is greater than the thickness of the door 14d).

In this embodiment, when the door 18d of the large freezer compartment 18 is pulled out, the second container 26 is open, so the user can use the second container 26 immediately. The hand portion 28h of the third container 28 can be immediately put on without being disturbed by the door 14d of the ice-making compartment 14 or the door 16d of the small freezer compartment 16 adjacent to the upper side, so that the operability is good.

Although the embodiments have been described above, the embodiments are presented as examples and are not intended to limit the scope of the invention. The novel embodiments can be implemented in various other aspects, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the scope of the invention described in the claims and equivalents thereof.

The structure of the refrigerator 1 shown in 1st Embodiment and 2nd Embodiment is an example to the last, and arbitrary structures can be employ|adopted.

For example, as shown in FIG. 10, the uppermost third container 28 may be composed of two left and right third containers 28u and 28v. This makes it easy to finely and accurately organize the contents in the uppermost container.

In order to have a structure in which the third containers 28u and 28v are pulled out together with the second container 26, for example, rail members 26r are provided on both sides of the third container 28u and on both sides of the third container 28v. placed. The laterally outer rail member 26r is arranged in the second container 26, and the laterally inner rail member 26r is supported by the partition portion 32 arranged between the third container 28u and the third container 28v. The third container 28u is provided with hooked portions on both sides thereof, and hooking portions are arranged on the rail members 26r on both sides of the third container 28v.

In order to provide a structure in which the third containers 28u and 28v are not pulled out together with the second container 26, for example, a structure in which the hooking portion and the hooked portion are not provided compared to the structure in which the third containers 28u and 28v are pulled out. As a result, the second container 26 and the third container 28 are not interlocked, so even if the second container 26 is pulled out, the third container 28 is not pulled out.

It should be noted that regardless of whether the third containers 28u and 28v are pulled out together with the second container 26 or not pulled out together with the second container 26, instead of the left-right inner rail member 26r supported by the partition 32, the partition 32 are provided with elongated flat plate-like flange-shaped guide portions for guiding the third container on both side surfaces in the left-right direction. may be formed.

In this case, the third containers 28u and 28v may have holes 28a1 formed in both side surfaces (side surfaces on both sides in the left-right direction), or may have holes 28a1 formed in one side surface (for example, when viewed from the front side of the container). It may be formed only on the widthwise outer side portion).

Also, the handle portion may be constructed so that the hand is put in from above, or it may be constructed so that the hand is put in from below.

Also, the color tones of the first to third containers may be different from each other. As a result, the stored items can be organized by color tone. The color tone is, for example, blue, green, white, etc., and may be transparent.

In the first and second embodiments, the first to third containers are arranged in the freezer compartment. It can be effective.

Also, although the example in which the first to third containers are arranged as the storage containers has been described, the number of containers stacked one above the other is not limited to three, and may be four, five, or more.

It is also possible to arrange the holes 24a1, 26a1, 28a1 in the upper part of the container instead of in the lower part.

Furthermore, the positions of the holes 28a1, 26a1, and 24a1 may sequentially change from the front to the rear as the container moves from the upper container to the lower container (that is, from the third container 28 to the first container 24). However, the position may be the front in order from the back. Also, the holes 26a1 and 28a1 do not have to extend over the bottom of the container.

At least part of the holes 24a1, 26a1, 28a1 may be formed in the front wall of the container, or may be formed in the rear wall of the container.

Further, the positions of the holes 24a1, 26a1, and 28a1 may be different between the left side and the right side of the container when viewed from the front side of the refrigerator.
