Description

refrigerator

The present disclosure relates to a refrigerator in which a plurality of drawers of storage containers are arranged in a storeroom provided in a refrigerator body.

A refrigerator has a plurality of storage compartments such as a freezer compartment or a refrigerator compartment inside the refrigerator body. The arrangement position of each storage room is often determined according to the use of each storage room. In a particularly large storage compartment on the lower side of the refrigerator, a storage container with an open top is designed to be pulled out and pushed into the refrigerator main body or the storage compartment in conjunction with the opening and closing of the drawer door. In that case, the storage container is often divided into a plurality of stages in the vertical direction, and it is not uncommon to have three stages of upper, middle and lower stages. Moreover, the handle of such a drawer door is arranged on the upper side of the drawer door.

A refrigerator described in Patent Document 1 is an example of a refrigerator in which three storage containers are stored in the storage chamber, upper, middle, and lower. In the refrigerator described in Patent Literature 1, a pair of frames are fixed to the back surface of the drawer-type door on the left and right sides, respectively, and the first storage container is arranged on the frames. Also, the second storage container is arranged on the flange sliding surface formed on the upper end portion of the side wall of the first storage container. A pair of rollers are provided at the front of both side walls of the second storage container, and a pair of projections projecting from the side walls are provided at the rear. The pair of rollers and the pair of protrusions of the second storage container are in contact with the flange sliding surfaces of the first storage container.

In the refrigerator described in Patent Document 1, when trying to take out the contents stored in the first storage container, it is done as follows. First, the first storage container is pulled forward in conjunction with the drawer-type door. At this time, the second storage container is pulled out together with the first storage container. Therefore, the user puts his or her hand on the second storage container arranged above the first storage container and pushes it inward. Then, the rollers of the second container that are in contact with the flange sliding surface of the first container move along the flange sliding surface, and the second container is pushed inward.

In the refrigerator described in Patent Document 1, a third storage container is provided above the second storage container so as to be movable in the front-rear direction. The third storage container is supported by rails provided on the left and right sides of the storage chamber. In the refrigerator described in Patent Literature 1, the first storage container and the second storage container are pulled out in conjunction with the drawer door while only the third storage container remains inside the refrigerator main body. When trying to take out the contents stored in the third storage container, the user pulls out the third storage container forward along the rail with the drawer type door opened to take out the contents.

However, in the refrigerator described in Patent Document 1, when an article is to be put in and taken out of the first storage container, the drawer-type door is pulled out to pull out both the first storage container and the second storage container, and then the second storage container is pulled out. Only the second storage container is moved rearward by sliding on the flange sliding surface of the first storage container. In that case, the second storage container moves on the first storage container while being supported on the first storage container, so the frontage of the opening of the first storage container is limited. As a result, there is a problem that it is inconvenient to put in and take out the articles stored in the back side of the first storage container.

On the other hand, for example, in the refrigerator described in Patent Document 2, rails are newly provided on the left and right sides of the storage compartment for storing the second storage container inside the storage compartment. When the user opens the drawer type door, the second storage container is pushed inward along the rail. Thereby, the second storage container can be moved from above the first storage container to above the rail, thereby moving to a position where it is completely stored in the refrigerator main body.

First, the configuration of the refrigerator 100 will be roughly explained. The details of the configuration of refrigerator 100 will be described later.

As shown in FIG. 5, fixed rails 14 extending in the Y direction are provided on left and right side walls of the refrigerator body 1 (specifically, left and right side walls of the freezer compartment 4). Left and right side walls of the refrigerator main body 1 (specifically, left and right side walls of the freezer compartment 4 ) are formed from an inner box 51 . The fixed rail 14 is sometimes called a "first support". Also, the second support portion 17 is arranged in the upward direction Z1 in the Z direction with respect to the fixed rail 14 . The second support portions 17 extend in the Y direction from left and right side walls of the freezer compartment 4 . The fixed rail 14 and the second support portion 17 are spaced apart from each other and arranged parallel or substantially parallel.

On the other hand, the door 11 is arranged parallel to the XZ plane and arranged at the opening of the freezer compartment 4, as shown in FIG. Further, the door 11 has a pair of left and right frames 12, as shown in FIG. The left and right frames 12 are rectangular plate-like members, each extending in the Y direction. The left and right frames 12 are arranged facing each other. The left and right frames 12 are arranged parallel to each other. Also, the height positions of the left and right frames 12 are the same. Each frame 12 is fixed to the rear surface 11a of the door 11, as shown in FIG. Therefore, the frame 12 extends from the back surface 11a toward the interior of the freezer compartment 4 in a direction crossing the back surface 11a. Further, the frame 12 has a bent portion 12a and rollers 13, as shown in FIG. The bent portion 12a is arranged at the lower end of the frame 12 in the longitudinal direction. The roller 13 is arranged at an end portion 12 b of the frame 12 on the far side. The bent portion 12a of the frame 12 and the roller 13 are arranged in the recessed portion 14a of the fixed rail 14, guided by the fixed rail 14, and slide in the recessed portion 14a of the fixed rail 14. As shown in FIG.

In addition, as shown in FIG. 6, the first storage container 20 has a first flange portion 21 on the side surface portion 20b. Since the first flange portion 21 is supported by the frame 12 , it moves in the Y direction in conjunction with the opening/closing operation of the door 11 . As a result, the first storage container 20 moves in the Y direction as the door 11 opens and closes. Further, the first storage container 20 has a support surface portion 23 that supports the second storage container 30, as shown in FIG.

Further, the second storage container 30 has a stepped portion 31 and a second flange portion 33 arranged above the stepped portion 31, as shown in FIG. The stepped portion 31 is placed on and supported by the support surface portion 23 of the first storage container 20 . As a result, the second storage container 30 moves in the Y direction together with the first storage container 20 as the door 11 is opened and closed. Also, when the user takes out the contents stored in the first storage container 20, the user pushes the second storage container 30 in the depth direction Y2 in the Y direction. At this time, the second flange portion 33 of the second storage container 30 slides on the support surface portion 23 . The second flange portion 33 of the second storage container 30 pushed backward in this manner is supported by the second support portions 17 (see FIG. 5) provided on the left and right side walls of the freezer compartment 4 .

Further, the third storage container 40 is provided with third projections 41 on the left and right side surfaces 40b. The third protrusion 41 is placed in contact with the upper surface of the stepped portion 31 of the second storage container 30 . A first protrusion 36 and a second protrusion 37 are provided on the upper surface of the stepped portion 31 of the second storage container 30 to restrict the movement of the third protrusion 41 in the Y direction. . The third protrusion 41 is fitted between the first protrusion 36 and the second protrusion 37 . As a result, the third storage container 40 moves in the Y direction together with the first storage container 20 and the second storage container 30 as the door 11 is opened and closed. Also, when the user takes out the contents stored in the second storage container 30, the user pushes only the third storage container 40 in the depth direction Y2 in the Y direction. At this time, the pushing force of the user causes the third protrusion 41 of the third storage container 40 to climb over the second protrusion 37 provided on the upper surface of the stepped portion 31 of the second storage container 30 . Also, the third storage container 40 has a third flange portion 43 on the side portion 40b. As the third flange portion 43 slides on the second support portions 17 provided on the left and right inner walls of the refrigerator body 1, the third container 40 moves rearward in the Y direction.

In Embodiment 1, a handle 11b that a user grips when opening and closing the door 11 is provided on the top of the door 11 . In Embodiment 1, two rails, ie, a fixed rail 14 as a “first support” and a second support 17 are provided on the left and right inner walls of the refrigerator body 1 . On the other hand, in Patent Document 2 mentioned above, three rails are provided. In Patent Literature 2, the three rails need to be spaced apart vertically, so the lower rail is placed considerably below the storage compartment. As a result, the distance in the height direction between the frame sliding in the lower rail and the handle of the door increases. Therefore, when the door is pulled out, a large rotational moment is generated between the frame and the handle of the door. On the other hand, in Embodiment 1, since the number of rails can be reduced, the position of the fixed rail 14, which is the lower rail, can be increased. Therefore, the height-direction distance L1 (see FIG. 6) between the frame 12 sliding in the lower rail and the handle 11b of the door 11 can be reduced. As a result, since the generation of rotational moment can be suppressed, the increase in the size and thickness of frame 12 attached to door 11 can be avoided, and the manufacturing cost of refrigerator 100 can be reduced.

The configuration of refrigerator 100 will be described in detail below with reference to FIGS. 3 to 8. FIG.

Moreover, the longitudinal direction of the first flange portion 21 extends in the Y direction. The first flange portion 21 may be provided over the entire length of the outer surface 20b1 in the Y direction, but as shown in FIG. may The first flange portion 21 is supported by the frame 12 of the door 11 . Therefore, the first storage container 20 moves in the front-rear direction (Y direction) as the door 11 is opened and closed. The first container 20 is placed on the frame 12 from above. Thus, the first storage container 20 is detachably supported by the frame 12 and further by the door 11 .

In addition, as shown in FIG. 6, the rear surface portion 20c of the first storage container 20 is one step lower than the left and right side surface portions 20b so that it does not come into contact with the second storage container 30. Further, the rear surface portion 20c of the first storage container 20 has a rear stopper portion 20d.

The bent portion 12a and the roller 13 are inserted into the concave portions 14a of the fixed rails 14 provided on the left and right side surfaces 18 of the freezer compartment 4. As shown in FIG. The roller 13 rotates on the upper surface of the lower projecting portion 19b, and the roller 15 rotates on the lower surface of the bent portion 12a of the frame 12. As shown in FIG. As a result, the “support frame 120 ” (the left and right frames 12 and the frame connecting portion 55 ) slides inside the concave portion 14 a of the fixed rail 14 . By assembling the fixed rails 14, the rollers 15, the frames 12, and the rollers 13 in this manner, the "support frame 120" moves along with the first storage container 20 as the door 11 opens and closes. is loaded and unloaded back and forth from the The "support frame 120" is moved in and out by opening and closing the door 11 (forward and backward movement). In addition, the first storage container 20 is also taken in and out by opening and closing the door 11 (forward and backward movement) together with the "support frame 120".

As shown in FIG. 6, the second storage container 30, which is the storage container in the middle stage, has a rectangular parallelepiped box shape with an open top and a bottom. The second storage container 30 is arranged above the first storage container 20 so as to cover the entire open upper surface of the first storage container 20 or substantially the entire upper surface. The second storage container 30 has a second storage container main body 30a with an open upper surface. The second storage container body 30a is shallower than the first storage container body 20a, and the volume of the second storage container body 30a is smaller than that of the first storage container body 20a.

The second storage container main body 30a has a pair of left and right side portions 30b, a back portion 30c, a front portion 30e, and a bottom plate 30d. A pair of left and right side portions 30b face each other. The rear portion 30c and the front portion 30e face each other.

As shown in FIG. 8, the upper end of the side surface portion 30b of the second storage container main body 30a protrudes outward (in the left-right direction) in two steps toward the upward direction Z1 in the Z direction. Specifically, the side surface portion 30b has a stepped portion 31 and a second flange portion 33 arranged above the stepped portion 31, thereby protruding outward in two steps.

The left and right stepped portions 31 are arranged at the upper ends of the left and right side portions 30b of the second storage container main body 30a, respectively, and protrude outward (lateral direction) in directions away from each other. The stepped portion 31 is arranged between the side portion 30b of the second storage container main body 30a and the second flange portion 33 . The stepped portion 31 is arranged inside and below the second flange portion 33 .

The longitudinal direction of the concave portion 32a extends in the Y direction. Further, as shown in FIG. 6, a rib 32b (stopper piece) extending downward is provided at the front end of the recess 32a.

As shown in FIG. 8, the second flange portion 33 extends upward from the outer edge portion 31b of the stepped portion 31, has a bent portion 33a at a position above the stepped portion 31, and protrudes outward. there is The longitudinal direction of the second flange portion 33 extends in the Y direction.

In addition, as shown in FIG. 6, the rear surface portion 30c of the second storage container 30 is one step lower than the left and right side surface portions 30b so that it does not come into contact with the third storage container 40. In addition, the second container 30 has projections 35 on the left and right in front of the lower surface of the bottom plate 30d. The projection 35 protrudes downward from the lower surface of the bottom plate 30d of the second storage container 30. As shown in FIG. The projection 35 has a 45-degree slope at the front edge and a nearly vertical surface at the rear edge. The size (height dimension) of the protrusion 35 in the Z direction is approximately 15 mm.

As shown in FIG. 6, the first storage container 20 is provided with support surface portions 23 extending in the Y direction and having left and right widths at the upper ends of the left and right side portions 20b. The left and right support surface portions 23 protrude outward from the left and right side portions 20b in directions away from each other. In addition, a locking portion 24 that protrudes upward is provided in front of the upper surface of the support surface portion 23 . The locking portion 24 engages with a rib 32b (stopper piece) provided at the front end of the concave portion 32a of the stepped portion 31 . The ribs 32b (stopper pieces) and the locking portions 24 are brought into contact with each other to restrain the movement of the second storage container 30 in the Y direction and the X direction with respect to the first storage container 20 . The recessed part 32a may be called a "receiving part." When at least part of the engaging portion 24 provided in the first storage container 20 is positioned within the recessed portion 32a, which is the "engagement portion", the Y direction of the second storage container 30 with respect to the first storage container 20 movement is suppressed.

The stepped portion 31 is placed on the support surface portion 23 of the first storage container 20 . At this time, the stepped portion 31 is placed on the support surface portion 23 so that the concave portion 32a of the stepped portion 31 vertically overlaps the support surface portion 23 of the first storage container 20, as shown in FIG.

As shown in FIG.

In addition, as shown in FIG. 6, the first storage container 20 is provided with an inclined surface portion 25 whose height decreases toward the rear at the rear end portion of the support surface portion 23 .

When the second storage container 30 is placed on the first storage container 20 , the engaging portion 24 of the first storage container 20 enters the concave portion 32 a of the second storage container 30 . Thereby, the locking portion 24 forms the front side surface of the recess 32a. When the second storage container 30 is viewed from the front, the front surface of the rib 32b (stopper piece) can be visually recognized. Then, the rib 32b (stopper piece) and the locking portion 24 abut against each other, so that the movement of the second storage container 30 in the Y direction with respect to the first storage container 20 is suppressed. In this manner, the second storage container 30 is constructed so that it can be taken in and out together with the first storage container 20 .

When the second storage container 30 is placed on the first storage container 20, the lower end 31a of the stepped portion 31 contacts the upper surface of the support surface portion 23, as shown in FIG. In this state, the second flange portion 33 is separated from the second support portion 17 and arranged above the second support portion 17, as shown in FIG. As an example, the second flange portion 33 has a gap of distance L2 with respect to the upper surface of the second support portion 17 . Note that the distance L2 is approximately 5 mm. That is, when the second storage container 30 is placed on the first storage container 20, the second flange portion 33 of the second storage container 30 is not in contact with the second support portion 17. . On the other hand, when the second storage container 30 is pushed rearward in the Y direction and comes down from the first storage container 20 , the second flange portion 33 of the second storage container 30 moves toward the second support portion 17 . It is placed on top and supported by the second support portion 17 .

Further, when the user pushes the second storage container 30 rearward with a force that exceeds the engagement force between the locking portion 24 and the rib 32b while the door 11 is pulled out, the locking portion 24 does not move toward the rib 32b. overcome. Then, the second storage container 30 slides rearward on the support surface portion 23, thereby moving the second storage container 30 rearward.

Then, when the second storage container 30 is slid further rearward, the second flange portion 33 of the second storage container 30 slides on the second support portion 17 (see FIG. 5). Become. As shown in FIGS. 5 and 8 , second support portions 17 are provided on left and right side surfaces 18 of the freezer compartment 4 formed by the inner box 51 . When the user pushes the second storage container 30 rearward while the door 11 is open, the second storage container 30 slides on the second support portion 17 and moves rearward, thereby moving the frozen container 30 backward. It is housed in room 4.

Then, when the second storage container 30 is slid further rearward, the projection 35 provided in front of the lower surface of the bottom plate 30d of the second storage container 30 is provided on the rear surface portion 20c of the first storage container 20. The second container 30 abuts against the rear stopper portion 20d and restrains the second storage container 30 from sliding rearward.

In addition, as shown in FIG. 6, a first protrusion 36 and a second protrusion 37 are formed on the upper surface of the stepped portion 31 of the second storage container 30 . The first protrusion 36 and the second protrusion 37 are protrusions protruding upward from the upper surface of the stepped portion 31 . The first protrusion 36 and the second protrusion 37 are arranged at different positions in the Y direction behind the center point of the second storage container 30 in the Y direction. Between the first protrusion 36 and the second protrusion 37, a third protrusion 41 of a third storage container 40, which will be described later, is fitted. Therefore, the first projecting portion 36 and the second projecting portion 37 are separated by a distance that allows the third projecting portion 41 of the third storage container 40 to fit therebetween. Compared with the first protrusion 36, the height of the second protrusion 37 is low. The second projecting portion 37 has a low and smooth inclined surface shape (mountain-like shape) with respect to the third projecting portion 41 of the third storage container 40 to be described later.

In addition, the second storage container 30 further has a recessed portion 38 on the upper surface of the stepped portion 31 . The recessed portion 38 is arranged behind the second projection portion 37 . The recessed portion 38 is recessed downward from the upper surface of the stepped portion 31 . The concave portion 38 has a gently sloping surface on the front side and a surface arranged at an angle close to vertical on the rear side.

Further, as shown in FIG. 6 , a rear flange portion 39 is formed behind the second flange portion 33 in the second storage container 30 . The Y-direction length (depth dimension) of the rear flange portion 39 corresponds to the Y-direction length (depth dimension) of the third flange portion 43 of the third container 40 . The height of the rear flange portion 39 in the Z direction is lower than that of the second flange portion 33 .

Next, the third storage container 40, which is the upper storage container, will be described. As shown in FIGS. 6 to 8, the third storage container 40 has a rectangular parallelepiped box shape with an open top. The third storage container 40 is arranged above the second storage container 30 so as to cover a portion of the open upper surface of the second storage container 30 . In Embodiment 1, as shown in FIG. 3, the third storage container 40 is arranged so as to cover the rear portion of the second storage container 30 in the Y direction. The third storage container 40 has a third storage container main body 40a with an open upper surface. The third storage container body 40a is shallower than the second storage container body 30a, and the volume of the third storage container body 40a is smaller than that of the second storage container body 30a.

The third storage container main body 40a has a pair of left and right side portions 40b, a back portion 40c, a front portion 40e, and a bottom plate 40d. A pair of left and right side portions 40b face each other. The rear portion 40c and the front portion 40e face each other.

In Embodiment 1, the third storage container 40 covers about half of the rear side of the second storage container 30, as shown in FIG. Therefore, the Y-direction size (depth dimension) of the third storage container 40 is about half that of the second storage container 30, but is not limited to this, and may be about the same.

The third storage container 40 is provided with a third projection 41 and a fourth projection 42 on the outer side faces 40b1 of the left and right side faces 40b. The third projecting portion 41 and the fourth projecting portion 42 are provided one each on the front side and the rear side along each of the left and right sides of the bottom plate 40d. Specifically, the third protrusion 41 is arranged in front of the fourth protrusion 42 in the Y direction. Therefore, the third protrusion 41 is the front protrusion, and the fourth protrusion 42 is the rear protrusion. Of the third protrusion 41 and the fourth protrusion 42, at least the third protrusion 41 may be called a "slider".

The third protrusion 41 is placed in contact with the upper surface of the stepped portion 31 of the second storage container 30 . Thereby, the third storage container 40 is slidably supported in the Y direction with respect to the second storage container 30 . On the other hand, when the third protrusion 41 is fitted between the first protrusion 36 and the second protrusion 37 of the second storage container 30 , the third protrusion for the second storage container 30 Movement of the storage container 40 in the Y direction is restricted.

The third protrusion 41 and the fourth protrusion 42 are made of the same resin material as the third storage container body 40a and the second storage container body 30a. The third projecting portion 41 and the fourth projecting portion 42 are attached by being inserted into the attaching portion 40b2 provided on the outer side surface 40b1 of the third storage container main body 40a. Alternatively, the third protrusion 41 and the fourth protrusion 42 may be integrally molded with the third storage container body 40a and the second storage container body 30a.

Further, the third storage container 40 has third flange portions 43 provided at the upper ends of the left and right side portions 40b. Furthermore, the third storage container 40 has a fifth projection 44 and a sixth projection 45 arranged below the third flange portion 43 . The fifth projecting portion 44 and the sixth projecting portion 45 are arranged side by side below the third flange portion 43 along the lower end portion of the third flange portion 43 . The fifth projecting portion 44 and the sixth projecting portion 45 are provided along the lower end portion of the third flange portion 43 one each on the front side and the rear side. Specifically, the fifth protrusion 44 is arranged in front of the sixth protrusion 45 in the Y direction. Therefore, the fifth protrusion 44 is the front protrusion, and the sixth protrusion 45 is the rear protrusion. The fifth projecting portion 44 and the sixth projecting portion 45 extend downward in the Z direction Z2 from the lower end portion of the third flange portion 43 . The fifth projecting portion 44 and the sixth projecting portion 45 slide on the second support portion 17 when the third storage container 40 is pushed rearward and stored in the freezer compartment 4. It is.

The third flange portions 43 of the third storage container 40 are arranged at the upper ends of the left and right side portions 40b and extend in the Y direction. Moreover, the third flange portion 43 has a width that spreads in the left-right direction. The third flange portion 43 is positioned on the second support portion 17 when the door 11 is open and the third storage container 40 is housed in the freezer compartment 4 . On the other hand, regardless of whether the door 11 is open or closed, when the third storage container 40 is placed on the second storage container 30, the third flange portion 43 is positioned as shown in FIG. It is located on the rear flange portion 39 of the container 30 . When the third flange portion 43 is placed on the rear flange portion 39 of the second storage container 30 , the third flange portion 43 is larger than the second flange portion 33 of the second storage container 30 . , located above in the Z direction.

Also, the third storage container 40 is installed on the second storage container 30 so that the third flange portion 43 is positioned directly above the rear flange portion 39 of the second storage container 30 . At this time, a gap of about 1 mm is created between the third flange portion 43 of the third storage container 40 and the rear flange portion 39 . Therefore, since no friction occurs between the third flange portion 43 and the rear flange portion 39, it is possible to suppress the occurrence of excessive friction when the third projection portion 41 slides on the stepped portion 31. can.

Further, the second storage container 30 has an upper side surface portion 34 above the stepped portion 31, as shown in FIG. The upper side surface portion 34 is arranged between the stepped portion 31 and the rear flange portion 39 . When the third storage container 40 is supported by the second storage container 30 , the left and right side surfaces 40 b of the third storage container 40 are arranged inside the upper side surface portion 34 . Further, when the first storage container 20 is pulled out from the freezer compartment 4 and both the second storage container 30 and the third storage container 40 are in the freezer compartment 4, the second flange portion 33 and the third 3 and the flange portion 43 are both supported by the second support portion 17 . Specifically, since the second flange portion 33 is placed on the second support portion 17 and the third flange portion 43 is placed on the rear flange portion 39, the third flange portion 43 is indirectly supported by the second support portion 17 .

By configuring the second storage container 30 and the third storage container 40 in such a manner, the third storage container 40 can be taken in and out together with the second storage container 30 when the door 11 is opened and closed. is. Further, when the user pushes the third storage container 40 rearward with the force that the third protrusion 41 of the third storage container 40 climbs over the second protrusion 37 behind the second storage container 30, , the third protrusion 41 of the third storage container 40 climbs over the second protrusion 37 . Thereby, the third storage container 40 can be slid on the second support portion 17 and moved backward. At this time, the second support portion 17 and the third flange portion 43 are in contact with each other.

After sliding, the third protrusion 41 of the third storage container 40 fits into the recess 38 of the second storage container 30, preventing the third storage container 40 from moving further rearward. Suppress.

Further, the user lifts the third storage container 40 to disengage the engagement between the third projecting portion 41 and the recessed portion 38, and slide the third storage container 40 further rearward. At this time, the fifth projecting portion 44 and the sixth projecting portion 45 provided below the third flange portion 43 slide on the second support portion 17 . As a result, the entire third storage container 40 is placed on the second support portions 17 formed on the left and right side surfaces of the freezer compartment 4 . Thus, the third storage container 40 is housed in the freezer compartment 4 while being supported by the second support portion 17 . Since the third storage container 40 is housed in the refrigerator main body 1, the opening of the second storage container 30 is fully opened.

When the user pushes the third storage container 40 rearward in the Y direction, such as when closing the door 11 , the rear end 46 of the third flange portion 43 of the third storage container 40 is positioned at the end of the freezer compartment 4 . It abuts on the rear ends of the second support portions 17 formed on the left and right side surfaces 18 and stops. Therefore, it is possible to prevent the third storage container 40 from moving too far rearward and falling off the second support portion 17 .

As described above, the first storage container 20 and the second storage container 30 contact each other with the locking portion 24 and the rib 32b, so that the second storage container 30 moves in the front-rear direction (that is, in the Y direction). directional movement) is suppressed. In addition, the second storage container 30 and the third storage container 40 are configured such that the third protrusion 41 is fitted between the first protrusion 36 and the second protrusion 37, Movement of the third storage container 40 in the front-rear direction (that is, movement in the Y direction) is suppressed. Since the frame 12 of the door 11 and the first storage container 20 are engaged with each other, the third storage container 40, the second storage container 30, and the first storage container 40, the second storage container 30, and the first storage container 40 are opened as the door 11 is pulled out. The container 20 is pulled out together.

Further, when the user puts in or takes out the contents of the third storage container 40 or the front contents of the second storage container 30, it is sufficient to open the door 11 only. On the other hand, when the user puts in and takes out the contents behind the second storage container 30, the third storage container 40 can be pushed backward. Furthermore, when the user puts in and takes out the stored items in the first storage container 20, the second storage container 30 may be pushed backward. Since the third storage container 40 is placed on the second storage container 30, the second storage container 30 and the third storage container 40 can be separated by pushing the second storage container 30 backward. move backwards at the same time. As a result, the opening of the first container 20 is opened.

Further, when the third storage container 40 is pushed backward while the second storage container 30 and the third storage container 40 are pulled out, the third storage container 40 is pulled out behind the second storage container 30 . The rearward movement of the container 40 stops once. This is because the third protrusion 41 of the third storage container 40 fits into the recess 38 of the second storage container 30 . In this state, the third container 40 is within reach of the user.

Similarly, when the second storage container 30 is pushed backward while the second storage container 30 and the third storage container 40 are pulled out, the second storage container 20 is pushed behind the first storage container 20 . , the rearward movement of the storage container 30 stops once. This is because the protrusion 35 of the second storage container 30 is engaged with the rear stopper portion 20d of the first storage container 20. As shown in FIG. In this state, the second container 30 is within reach of the user.

In this way, when the third storage container 40 or the second storage container 30 is pushed rearward, the third storage container 40 is pushed behind the respective storage container and within reach of the user. storage container 40 or the second storage container 30 stops once. Therefore, when the user wants to take out the contents of the third storage container 40 or the second storage container 30, the user can pull out the third storage container 40 or the second storage container 30 again.

From the above configuration, in the refrigerator 100 of Embodiment 1, the support portions arranged on the left and right side surfaces 18 of the freezer compartment 4 and extending in the Y direction are composed of the fixed rails 14 as first support portions and the second support portions. 17 and two rails. The conventional refrigerator described above is provided with three support portions. Therefore, the fixed rail 14, which is the lower rail, can be positioned higher than in the conventional refrigerator. Therefore, the vertical distance between the handle arranged on the upper front surface of the door and the frame of the door can be made smaller than in the conventional refrigerator. Therefore, when the door 11 is opened and closed, the rotational moment generated between the handle 11b of the door 11 and the fixed portion of the frame 12 can be reduced. Therefore, the direction in which the door 11 is pulled out approaches the direction of the user's force to pull out the door 11, and the door 11 and the frame 12 do not wobble. As a result, the first storage container 20, the second storage container 30 and the third storage container 40 can be drawn out smoothly. In addition, since the frame 12 is not subjected to excessive rotational torque, the load on the fixed portion where the frame 12 and the door 11 are fixed can be reduced. As a result, an increase in the size of the frame 12 and an increase in the plate thickness of the frame 12 can be avoided.

In addition, in Embodiment 1, the usability of the storage containers stored in the freezer compartment 4, which is a storage room, is maintained by arranging the storage containers in three stages. As described above, in Embodiment 1, the manufacturing cost of refrigerator 100 can be reduced while maintaining usability due to smooth loading and unloading of storage containers stored in freezer compartment 4 as a storage compartment.

In addition, in Embodiment 1, the third storage container 40 and the second storage container 30 may each be made of a transparent material, that is, a transparent material. In this case, the user can grasp the contents of the items stored in the third storage container 40 and the second storage container 30 at a glance. Therefore, it is desirable that the third storage container 40 and the second storage container 30 are each made of a transparent material. In that case, the third storage container 40 and the second storage container 30 are made of, for example, resin that transmits light.

Embodiment 2.
FIG. 9 is a perspective view showing the configuration of a third storage container provided in the refrigerator according to Embodiment 2. FIG. In Embodiment 2, the same parts as those in Embodiment 1 are denoted by the same reference numerals, and description thereof is omitted, and only different parts will be described.

In the third storage container 40 provided in the refrigerator 100 of Embodiment 2, two slider members 47 are provided instead of the third projection 41 and the fourth projection 42 in Embodiment 1 described above. is provided. The slider member 47 is made of a material different from that of the second storage container 30, which is the middle storage container. Other configurations are the same as those of the first embodiment.

In the second embodiment, as shown in FIG. 9, an attachment portion 49 for attaching the slider member 47 is provided on the outer side surface 40b1 of the side surface portion 40b of the third storage container 40. As shown in FIG. A slider portion 56 is formed by attaching the slider member 47 to the attachment portion 49 . The slider member 47 is made of a material different from that of the second storage container 30 .

On the other hand, the mounting portion 49 is integrally molded with the outer surface 40b1 of the side surface portion 40b of the third storage container 40. As shown in FIG. Therefore, the mounting portion 49 is made of the same resin material as the second storage container 30 and the third storage container 40 .

As described in the first embodiment, when the third storage container 40 and the second storage container 30 are made of the same transparent resin material, the contents can be grasped at a glance. . However, in that case, the third protrusion 41 and the fourth protrusion 42 of the third storage container 40 and the second storage container 30 are made of the same material. The third protrusion 41 of the third storage container 40 slides on the second storage container 30 . When the members that slide against each other are made of the same material, the frictional force (friction coefficient) is higher than when they are made of different materials.

Therefore, in the second embodiment, a slider member 47 made of a different material is provided on the third storage container 40 instead of the third protrusion 41 and the fourth protrusion 42 of the third storage container 40. It is attached by being inserted into the attachment portion 49 . Thereby, the frictional force (or coefficient of friction) between the slider member 47 of the third storage container 40 and the second storage container 30 can be reduced. When the slider member 47 and the second storage container 30 are made of different materials, the frictional force (or coefficient of friction) can be reduced compared to when they are made of the same material. . However, it is more desirable that the combination of the material of the slider member 47 and the material of the second storage container 30 be a combination of materials that reduces the frictional force (coefficient of friction) as much as possible. Examples of the material of the slider member 47 include POM (Polyoxymethylene) material having excellent slidability.

As described above, in Embodiment 2, the slider member 47 provided on the third storage container 40 is made of a material different from that of the second storage container 30 . Thereby, the frictional force (friction coefficient) between the slider member 47 of the third storage container 40 and the second storage container 30 can be reduced. As a result, the problem that the slider member 47 of the third storage container 40 and the second storage container 30 are difficult to slide can be avoided.

Embodiment 3.
FIG. 10 is a cross-sectional view showing the configuration of a third storage container provided in the refrigerator according to Embodiment 3. FIG. In Embodiment 3, the same parts as those in Embodiment 1 are denoted by the same reference numerals, and descriptions thereof are omitted, and only different parts will be described.

In third storage container 40 provided in refrigerator 100 of Embodiment 3, similarly to Embodiment 2, instead of third projection 41 and fourth projection 42 in Embodiment 1 described above, , two slider members 47 are provided. Other configurations are the same as those of the first embodiment.

The difference between Embodiment 2 and Embodiment 3 is that, in Embodiment 3, as shown in FIG. , a fixing opening 60 is provided on the rear inclined surface 36a (that is, the rear surface) of the first protrusion 36. As shown in FIG. The fixing opening 60 is a through hole penetrating through the plate thickness of the first protrusion 36 . Alternatively, the fixing opening 60 may be a recess that is provided in the first protrusion 36 and has a concave shape toward the front.

Further, in the third embodiment, as shown in FIG. 10, the front slider member 47 of the two slider members 47 is formed with a convex insertion portion 48 projecting forward in the Y direction on the front surface thereof. ing. The insertion portion 48 is fitted into the fixing opening 60 .

Other configurations are the same as in the second embodiment.

In Embodiments 1 and 2 described above, the third storage container 40 and the second storage container 30 are only fixed in the height direction. Therefore, when the door 11 is pulled out forcefully, the third storage container 40 may bounce and generate an abnormal noise. Therefore, in Embodiment 3, the third storage container 40 is formed with the convex insertion portion 48 , and the second storage container 30 is formed with the fixing opening 60 . By fitting the insertion portion 48 into the fixing opening 60, the third storage container 40 and the second storage container 30 are fixed. As a result, the vertical movement of the third storage container 40 can be suppressed by fitting the insertion portion 48 and the fixing opening 60 . Therefore, it is possible to prevent the third storage container 40 from jumping, and to reduce the occurrence of noise.

In addition, in Embodiment 3, an example in which the insertion portion 48 is provided in the slider member 47 shown in Embodiment 2 has been described. However, the insertion portion 48 may be provided in the third projection portion 41 shown in the first embodiment without being limited to that case. In that case, similarly, the fixing opening 60 is provided in the first protrusion 36 . By fitting the insertion portion 48 of the third protrusion 41 into the fixing opening 60, the third storage container 40 and the second storage container 30 are fixed.

As described above, in Embodiment 3, the third storage container 40 is formed with the convex insertion portion 48 and the second storage container 30 is formed with the fixing opening 60 . By fitting the insertion portion 48 into the fixing opening 60, the third storage container 40 and the second storage container 30 are fixed. As a result, the movement of the third storage container 40 in the vertical direction can be restricted, so that the third storage container 40 can be prevented from bouncing and abnormal noise can be suppressed.

Also in Embodiment 3, as described in Embodiments 1 and 2, the slider portion 56 (in Embodiment 1, the third protrusion 41) is provided on the stepped portion 31. By being fitted between the first protrusion 36 and the second protrusion 37, movement of the third storage container 40 in the Y direction is restricted. As a result, in the third embodiment, movement in the Y direction and movement in the vertical direction of the third storage container 40 can be restricted.

In addition, the present disclosure is not limited to the configurations of Embodiments 1 to 3 described above and shown in the drawings. In particular, the interior of the refrigerator body 1 on the back side of the door 11 may be a storeroom other than the freezer compartment 4, and the number of storage containers stored in the storeroom including the freezer compartment 4 is three.
