Description

refrigerator

The present invention relates to a refrigerator, and more particularly to a configuration that improves the rigidity of the refrigerator body.

In recent years, refrigerators have been improved from the viewpoints of energy saving and space saving capacity, while improving the heat insulation performance of the refrigerator body and reducing the wall thickness of the refrigerator. Specifically, the refrigerator has an outer box and an inner box, and a foam heat insulating material is filled between them and a vacuum heat insulating material is arranged. With such a configuration, the heat insulation of the refrigerator main body is improved, and the wall thickness is reduced to realize space saving and large capacity.

Recently, the capacity has been further increased due to changes in the living environment. For this reason, increasing the rigidity of the refrigerator body is becoming a major issue.

In order to cope with such problems, the conventional refrigerator main body has been devised in various ways to increase its rigidity (for example, see Patent Document 1).

FIG. 34 shows the configuration of the refrigerator body described in Patent Document 1. As shown in FIG. 34, the refrigerator main body 3400 has an outer box 3403. The outer box 3403 includes a top plate 3401 and side plates 3402. The outer box 3403 includes a substantially L-shaped frame reinforcing member 3404 along the lower side of each side plate 3402. Further, the front side of the side plate 3402 is connected by a front plate member 3405. Further, the front plate member 3405 and the frame reinforcing member 3404 are connected by a screw 3406 at the position of the lower corner portion on the front side of the outer box 3403.

According to such a conventional configuration, since the side plate 3402, the front plate member 3405, and the frame reinforcing member 3404 are connected, the rigidity of the outer box 3403, that is, the refrigerator main body 3400 can be increased.

However, in recent refrigerators, in addition to the increase in size of the refrigerator main body 3400 described above, the door is configured with a glass door from the viewpoint of improving the quality, and the weight of the refrigerator is considerably combined with the weight of the refrigerator main body and the glass door. It's getting bigger. Therefore, it is becoming difficult to endure long-term use only with the conventional configuration as described above that increases the rigidity of the refrigerator body.

Especially, as described above, since the wall thickness of recent refrigerators is reduced in order to save space and increase capacity, there is a concern that the refrigerator main body 3400 may be deformed when used for a long period of time.

In addition, since the door as described above is cantilevered, the portion of the refrigerator body side plate that pivotally supports the door cannot withstand the cantilever moment load of the door and slightly deforms over time. There is a fear. Further, in the case of a double door, a step is generated between the left and right doors, and this may become apparent as time passes.

In particular, when the size of the left and right doors of the double doors is large and the other is small, the size of the cantilever moment load of the door applied to the left and right side plates of the refrigerator main body is different, so deformation is likely, It will be big.

In general, the refrigerator is configured such that the refrigerator main body is partitioned into a plurality of storage rooms such as a refrigerator room, a freezer room, a vegetable room, and the like by a partition plate, and each storage room can be opened and closed by a door. . In such a refrigerator, the storage room between the refrigerator compartment and the freezer compartment is further divided into two rooms on the left and right, one of which is an ice making room and the other is a freezer room or a switching room that can be switched between temperature zones. Is known (for example, see Patent Document 2).

FIG. 35 shows the refrigerator described in Patent Document 2. The refrigerator shown in FIG. 35 is provided with a refrigerator compartment 3502, a freezer compartment 3503, and a vegetable compartment 3504 in a refrigerator main body 3501. In addition, a storage room between the refrigerator compartment 3502 and the freezer compartment 3503 is divided into left and right rooms, and an ice making room 3505 and a freezer room or a switching room 3506 are provided. The ice making chamber 3505 and the freezer chamber or the switching chamber 3506 are divided as follows. That is, the end surface of the upper vertical partition 3509a projecting downward from the upper partition plate 3508 and the end surface of the lower vertical partition body 3509b projecting upward from the lower partition plate 3510 are brought into contact with and contacted with each other. A decoration cover (not shown) is arranged on the rear side, and a partition plate (not shown) is installed behind the decorative cover, so that the partitioning is performed.

The refrigerator configured as described above is provided with a freezer room or a switching room 3506 in addition to the refrigerator room 3502, the freezer room 3503, and the vegetable room 3504, so that meat and fish are stored in a semi-frozen state. It has the advantage of being easy to use.

In addition, since the freezer room or the switching chamber 3506 is positioned at the substantially central portion of the refrigerator main body 3501 in the vertical direction, the upper and lower partition plates that define the freezer chamber or the switching chamber 3506 and the like are substantially at the center of the opening of the long thin refrigerator main body 3501. There is also an advantage that the rigidity of the refrigerator main body 3501 is increased by becoming a strength member that reinforces the portion.

However, in recent refrigerators, the size of the refrigerator main body 3501 is increasing due to changes in the living environment, and as described above, the doors are becoming glass doors and are becoming heavier from the viewpoint of high quality. For this reason, the refrigerator main body 3501 is required to have a higher level of rigidity, and improvement in rigidity is becoming a major issue.

Especially, when the size of the refrigerator main body 3501 is increased, the size of the refrigerator main body is increasing in the horizontal direction instead of the vertical direction due to the height of the user. For this reason, the upper partition plate and the lower partition plate, which are also strength members of the refrigerator main body 3501, have large lateral dimensions, and if the plate thickness is kept at the current level, the function as the strength member cannot be fully exhibited. Also from this point, the improvement of the rigidity of the refrigerator main body 3501 has become a big problem.

Conventionally, among the doors for opening and closing the refrigerator compartment, the freezer compartment, the vegetable compartment, etc., the door for opening and closing the refrigerator compartment is pivotally supported by the refrigerator main body by a hinge. A reinforcing plate is additionally installed in the door hinge mounting portion to improve the strength of the hinge mounting portion and prevent deformation of the hinge mounting portion, door lowering, and the like (for example, see Patent Document 3).

36 and 37 show the door support structure of the refrigerator described in Patent Document 3. FIG. As shown in FIGS. 36 and 37, in the conventional door support structure, a reinforcing plate 3604 is provided on the rear surface of the front partition plate 3603 on the front surface of the partition wall 3602 to which the hinge member 3601 is attached and fixed. A hinge member 3601 is fixed to the reinforcing plate 3604 with screws 3605. With such a configuration, the load of the door 3606 is supported by the reinforcing plate 3604, and deformation of the front partition plate 3603 serving as a hinge attachment portion and door lowering are reduced.

It should be noted that the reinforcing plate 3604 has both end portions 3604a fixed to the left and right end surfaces of the partition wall 3602, and integrated with the partition wall 3602, thereby improving the strength of the partition wall 3602 and the partition front plate 3603. In FIG. 36, a heat insulating material 3607 is provided at the front end portion of the partition wall 3602.

However, as described above, recent refrigerators are becoming larger, and the front plate of the door is made of a glass plate from the viewpoint of improving the quality, and the door is heavier.

For this reason, the load applied to the hinge mounting portion is also increasing, and the conventional reinforcement plate 3604 arranged on the back surface of the front partition plate 3603 is fixed and integrated with the partition wall 3602 to support the door load. With this configuration, sufficient support strength cannot be obtained, and the strength of the hinge mounting portion is further increased.

Also, as described above, generally, a refrigerator is provided with a partition plate in the refrigerator body, and a storage room such as a refrigerator room, a freezer room, and a vegetable room is formed. A partition plate, for example, a partition plate for partitioning between a refrigerator compartment and a freezer compartment, is filled with urethane foam in the interior, as is the space between the inner box and the outer box constituting the refrigerator body. Is configured to have a heat insulating property (see, for example, Patent Document 4).

FIG. 38 shows a refrigerator described in Patent Document 4. The refrigerator shown in FIG. 38 has a refrigerator main body 3800 divided into a refrigerator compartment 3802 and a freezer compartment 3803 by a heat insulating partition plate 3801. The partition plate 3801 is filled with urethane foam 3804 in the hollow portion between the upper surface plate 3801a and the lower surface plate 3801b.

The refrigerator described in Patent Document 4 has high heat insulating properties because urethane foam 3804 is filled in a partition plate 3801 for heat insulation. Therefore, there is an advantage that heat insulation can be ensured without reducing the thickness of the partition plate 3801 and reducing the volume of the refrigerator compartment 3802 and the freezer compartment 3803. In particular, since the refrigerator compartment 3802 and the freezer compartment 3803 have greatly different cooling temperature zones, the heat insulating effect is great if applied to a partition plate that partitions the two.

However, since the upper surface plate 3801a and the lower surface plate 3801b of the partition plate 3801 are made of polypropylene resin, the adhesion with the urethane foam 3804 is poor. Therefore, in some cases, separation occurs between the partition plate 3801 and the urethane foam 3804, and floating deformation or the like occurs in a part of the upper surface plate 3801a that becomes the bottom of the refrigerator compartment of the partition plate 3801 having heat insulation properties. There is.

One of the objects of the present invention is to provide a refrigerator that suppresses deformation of the main body of the refrigerator that has become heavy even when used for a long period of time and does not reduce reliability.

Specifically, a refrigerator according to an example of the embodiment of the present invention includes a refrigerator body having a plurality of storage rooms and a plurality of doors for opening and closing the plurality of storage rooms. The refrigerator body includes an outer box, an inner box, and a foam heat insulating material filled between the outer box and the inner box. The refrigerator body further includes a plurality of side plate portions and a bottom plate portion. The storage chamber disposed at the lowermost of the plurality of storage chambers has a corner portion that serves as a connection portion between each of the plurality of side plate portions and the bottom plate portion, and the corner portions are both on the side plate portion side and the bottom plate portion side. , The first thick wall portion thicker than the wall thickness of the wall of the refrigerator body other than the corner portion is provided.

With such a configuration, the rigidity of the refrigerator main body can be greatly improved at the lower end of the side plate portion of the refrigerator main body, which has a high ratio of receiving the total weight of the heavy refrigerator main body, and the total load of the refrigerator main body and the door can be increased over a long period of time. Even if it keeps supporting, it can prevent that a refrigerator main body deform | transforms. And since each corner part of the side-plate part side and bottom-plate part side of a refrigerator main body lower part is equipped with the 1st thick wall part thicker than the wall thickness of another part, around the storage chamber of the refrigerator main body lowermost part As compared with the case where the wall thickness of the entire wall is increased, it is possible to prevent deformation without greatly reducing the capacity.

This makes it possible to prevent deformation of the refrigerator body for a long period of time without greatly reducing the capacity of the refrigerator body. Therefore, the reliability with respect to a refrigerator can be maintained, and a space-saving large capacity and highly reliable refrigerator can be provided.

Further, in the refrigerator according to an example of the embodiment of the present invention, one of the doors that opens and closes the plurality of storage rooms is configured with a double door, and one of the double doors is formed larger than the other, You may have a small door. In this case, among the plurality of side plate portions, the side plate portion of the refrigerator body on the side where the large door is pivotally supported is thicker than the wall thickness of the side plate portion of the refrigerator body on the side where the other small door is pivotally supported. A thick wall is provided. Furthermore, a partition plate disposed on each of the upper part and the lower part of the second thick wall part and a square frame part having the second thick wall part on the side are disposed in the refrigerator main body.

With such a configuration, the strength of the side plate portion of the refrigerator body to which a large door cantilever moment load is directly applied is enhanced by the second thick wall portion. In addition, since the square frame portion having the second thick wall portion on one side is arranged in the refrigerator body, the rigidity of the portion directly below the door shaft support of the refrigerator body is increased, and the cantilever moment load of the door is received. Even if it continues, it can resist the cantilever moment load of a door and can suppress a deformation | transformation of a refrigerator main body. Therefore, even if it is used for a long time, there is no step between the left and right doors of the double doors, and a highly reliable refrigerator can be obtained.

Also, in the refrigerator according to an example of the embodiment of the present invention, the lowermost storage chamber of the refrigerator body among the plurality of storage chambers has a corner portion that serves as a connection portion between the side plate portion and the bottom plate portion. A corner part is provided with the 1st thick wall part thicker than the wall thickness of the wall of the refrigerator main body of other parts other than a corner part in both a side-plate part side and a baseplate part side. Furthermore, one of the plurality of doors is constituted by a double door, and one of the double doors is formed larger than the other, and has a large door and a small door. Of the plurality of side plate portions, the side plate portion of the refrigerator body on the side that pivotally supports the large door has a second thick wall portion that is thicker than the wall thickness of the side plate portion of the refrigerator body on the side on which the other small door is pivotally supported. Prepare. Furthermore, in the refrigerator according to the example of the embodiment of the present invention, the rectangular frame portion having the partition plates arranged on the upper and lower portions of the second thick wall portion and the second thick wall portion on the side includes the refrigerator main body. It is arranged in the inside.

With such a configuration, a refrigerator that combines the effects of providing the above-described first thick wall portion, the effects of providing the second thick wall portion, and the effect of providing the square frame portion. Can be provided. That is, the portion directly below the door support portion (second thick wall portion) of the side plate portion of the refrigerator body that intensively supports the load of the door, and the lower portion of the refrigerator body that receives the total weight of the refrigerator body (first (Thick wall portion) The rigidity of each can be increased, and the entire refrigerator body can be made tougher. Therefore, it is possible to provide a highly reliable refrigerator with little deformation of the refrigerator body even when used for a long time.

In addition, the refrigerator according to an example of the embodiment of the present invention has a stepped portion of the side plate portion formed by the first thick wall portion having a thick wall thickness of the corner portion, and a storage chamber disposed at the lowermost portion of the refrigerator body. A container rail provided so as to be freely put in and out may be provided.

With such a configuration, the container can be installed in a state where it floats from the bottom surface of the storage room using the first thick wall portion, and the rail installation can be rationalized. Furthermore, even if condensed water forms on the bottom of the storage room and accumulates, it can be prevented that the rails are immersed in the condensed water and the condensed water adhering to the rails freezes or the rails rust and cause malfunctions. In addition, a highly reliable refrigerator can be provided.

Further, in the refrigerator according to the example of the embodiment of the present invention, the step portion of the bottom plate portion formed by the first thick wall portion having the thick wall thickness of the corner portion has a top surface in front of the storage chamber having the corner portion. You may be made to incline so that it may become low toward an opening edge part.

Such a configuration can prevent the bottom surface of the container from rubbing against the top surface of the stepped portion even when the container is pulled down due to the weight of the container when the container is pulled out. That is, it is possible to prevent the appearance facing from being deteriorated due to scratches on the portion facing the opening of the storage chamber.

Further, in the refrigerator according to the example of the embodiment of the present invention, the rectangular frame portion having the partition plates arranged on the upper and lower portions of the second thick wall portion and the second thick wall portion on the sides is vertically arranged. The storage chamber divided into the left and right storage chambers by the partition may be formed such that one of the storage chambers has a larger volume than the other. The side plate part of the refrigerator main body on the side where the storage room having a large volume among the storage rooms divided into right and left may be provided with a second thick wall part.

With such a configuration, the square frame portion is divided into two left and right storage chambers by the vertical partition, whereby the rigidity of the square frame portion itself can be further improved. At the same time, the second thick wall portion can improve the strength of the storage chamber, which has a large volume, has a wide opening, and tends to be weak. Therefore, the deformation | transformation of a refrigerator main body can be suppressed further effectively and the reliability of a refrigerator can be improved greatly.

Further, in the refrigerator according to the example of the embodiment of the present invention, a vacuum heat insulating material may be arranged on a part of the side plate portion of the refrigerator main body. In this case, the vacuum heat insulating material is disposed so that the lower end of the vacuum heat insulating material does not overlap the first thick wall portion at the lower portion of the side plate portion, and the corner portion between the side plate portion and the bottom plate portion of the refrigerator main body is foamed as the heat insulating material. Only the heat insulating material is used and formed.

With such a configuration, the corner portion of the side plate portion and the bottom plate portion of the refrigerator main body is filled only with a foam heat insulating material having rigidity higher than that of the vacuum heat insulating material. It is higher than when letting go. Therefore, the deformation of the refrigerator body can be strongly prevented and the reliability can be further enhanced.

The refrigerator according to an example of the embodiment of the present invention further includes a partition plate that partitions the inside of the refrigerator body into a plurality of storage chambers, and one of the plurality of storage chambers is divided into left and right by a vertical partition, The upper and lower partition plates of the storage chamber divided into two parts may be configured by being connected by a vertical partition.

With such a configuration, the upper partition plate and the lower partition plate constituting the storage chamber divided into the left and right are connected by the vertical partition, so that the torsional force applied to the storage chamber divided into the left and right , They will reinforce each other. Furthermore, even if the horizontal width dimension of the storage room is large, the horizontal width in the left-right direction is divided into two parts by a vertical partition, and the storage room divided into the left and right functions as a strength member. Thereby, even if a width width dimension is large, the rigidity of a refrigerator can be improved greatly. Therefore, even if a twisting force or the like is applied to the refrigerator main body when the door is opened or closed, this can be resisted. At the same time, even if the door is made of a glass material or the like and becomes heavy, it can resist the weight of the door, and the deformation of the refrigerator main body can be strongly suppressed. In addition, even if the refrigerator body is enlarged in the horizontal width direction and the left and right horizontal dimensions of the upper partition plate and the lower partition plate of the storage room divided into left and right are increased, the upper partition plate and the lower partition plate are And since it is connected by the vertical partition in a part in the width direction, it can prevent that an upper part partition plate and a lower part partition plate deform | transform into a drum shape. Thereby, the flatness of the refrigerator body can be increased, and a high-quality refrigerator with high dimensional accuracy can be provided, and at the same time, the rigidity of the refrigerator body can be increased, and a large-sized and high-quality refrigerator can be provided. it can.

In the refrigerator according to the example of the embodiment of the present invention, the vertical partition may be integrally formed with at least one of the upper partition plate and the lower partition plate. Further, the upper partition plate and the lower partition plate may be connected by fitting (a fitting method) between the engaging portion and the engaged portion provided in the vertical partition.

With such a configuration, the connection between the upper partition plate and the lower partition plate can be performed simply by fitting the engaging portion and the engaged portion provided in the vertical partition, and screws are used. Compared to the case, the connecting operation can be performed easily and quickly. In addition, since the vertical partition is integrally formed with at least one of the upper partition plate and the lower partition plate, the number of parts can be reduced, and it can be provided at a low cost in combination with a reduction in working hours.

In the refrigerator according to an example of the embodiment of the present invention, the vertical partition may have a vertical partition and a vertical partition. In this case, the vertical partition is integrally formed with the upper partition plate so as to protrude downward from the upper partition plate, and the lower vertical partition is protruded upward from the lower partition plate. It may be integrally formed with the lower partition plate. In addition, a hook portion may be provided on one of the butt joint end surfaces on the vertical partition and the bottom of the vertical partition, and a recess into which the hook portion is fitted may be formed on the other.

With such a configuration, the upper partition plate and the lower partition plate are connected by simply fitting the hook portion provided on one of the vertical partition and the lower partition into the recess provided on the other. Therefore, the connecting operation can be performed easily and quickly as compared with the case of screwing. In addition, since the upper and lower vertical partitions are integrally formed with the upper and lower partition plates, respectively, the number of parts can be reduced, and it can be provided at a low cost in combination with a reduction in working hours. Is possible.

In addition, the refrigerator according to an example of the embodiment of the present invention has a storage room divided into left and right among a plurality of storage rooms, one of which has a larger volume than the other, Among them, the side plate portion of the refrigerator main body on the side where the storage chamber formed with a large volume is arranged is the side plate portion of the refrigerator main body on the side where the storage chamber formed with a small volume is arranged among the left and right storage chambers. It may be formed thicker than the side plate portion.

With such a configuration, among the storage rooms divided into the left and right two rooms, the rigidity of the large storage room, which tends to be weak due to the large opening, can be increased by the thick side plate, The rigidity can be further increased.

Further, in the refrigerator according to an example of the embodiment of the present invention, the storage room located at the upper part of the storage room divided into right and left includes a double door, and one of the double doors is larger than the other, and is large. You may have a door and a small door.

You may be comprised so that a volume may become larger than a storage chamber. Furthermore, in the refrigerator according to the example of the embodiment of the present invention, the side plate portion of the refrigerator main body on the side where the large volume storage chamber is arranged is walled from the side plate portion of the refrigerator main body on the side where the small volume storage chamber is arranged. You may be comprised so that thickness may become thick.

Such a configuration increases the rigidity of the storage chamber having a larger volume among the storage chambers divided into left and right even if the opening is large and the strength tends to be weak. At the same time, it is possible to increase the strength of the side plate portion of the refrigerator body where the large door cantilever moment load is directly applied. Therefore, even if the door is composed of a glass door or the like and the refrigerator becomes heavier, deformation of the refrigerator body can be effectively suppressed.

Further, the refrigerator according to an example of the embodiment of the present invention is resistant to the heavy weight even if the door is enlarged and the glass door is made large (the door is made of a heavy material such as a glass plate). You may be comprised so that a door can be supported firmly.

Specifically, the refrigerator according to an example of the embodiment of the present invention is disposed on the front surface of the refrigerator main body, the partition plate that partitions the inside of the refrigerator main body, the partition front plate that covers the front surface of the partition plate, and the front partition plate. You may provide the hinge member and the reinforcement metal fitting arrange | positioned at the back surface of the front partition plate facing a hinge member. In this case, the hinge member is fixed to the front surface of the partition plate together with the partition plate and the reinforcing metal fitting. At the same time, the end of the reinforcing bracket extends to the front end surface of the side plate portion of the refrigerator body, and the extended piece of the reinforcing bracket is fixed to the front end surface of the side plate portion of the refrigerator body together with the end portion of the partition front plate.

With such a configuration, the reinforcing bracket for supporting the door load is configured to be integrated with the side plate portion of the refrigerator main body together with the partition plate to support the door load applied to the reinforcing bracket. In other words, the door load applied to the reinforcing bracket is supported by the side plate portion of the refrigerator main body together with the partition plate. For this reason, the strength of the hinge mounting portion can be greatly improved. In other words, the hinge member mounting portion is able to greatly improve the strength of the hinge mounting portion by adding a reinforcing effect by fixing the extension piece of the reinforcing bracket to the refrigerator body side plate. Therefore, even if the door is increased in weight, it is possible to effectively suppress the deformation of the hinge mounting portion, the door lowering, etc., and provide a highly reliable refrigerator.

Further, in the refrigerator according to the example of the embodiment of the present invention, a part of the hinge member is fixed together with the extension piece portion of the reinforcing metal fitting and the end portion of the partition front plate at the front end surface of the side plate portion of the refrigerator main body. May be.

With such a configuration, the hinge member is directly supported also by the side plate portion of the refrigerator main body, and the door lowering and the like can be effectively prevented by the support by both the refrigerator main body side plate portion and the partition plate. it can.

In the refrigerator according to the example of the embodiment of the present invention, the partition plate may include an upper partition plate cover and a lower partition plate cover, and these may be combined. In this case, the front plate of the upper partition plate cover and the lower partition plate cover that constitute the front surface of the partition plate may be overlapped and fixed.

With such a configuration, the strength of the front surface of the partition plate for fixing the hinge member, the front partition plate and the reinforcing bracket can be improved. Therefore, the strength of the hinge mounting portion can be further improved, and the door can be prevented from falling down more effectively.

Further, the refrigerator according to an example of the embodiment of the present invention may be configured by filling the partition plate with a foam heat insulating material.

With such a configuration, the strength of the partition plate itself is increased by the foam heat insulating material, and the strength of the hinge mounting portion can be further improved.

Further, in the refrigerator according to an example of the embodiment of the present invention, a reinforcing member may be mounted on the inner surface of the front plate of the partition plate, and the reinforcing member may be protruded into the foam heat insulating material.

With such a configuration, the strength of the front plate portion of the partition plate can be greatly improved by the reinforcing member protruding into the foam heat insulating material. Therefore, the strength of the hinge mounting portion is greatly improved, and the door can be lowered more effectively.

Further, a refrigerator according to an example of the embodiment of the present invention includes a refrigerator body, a partition plate that forms a plurality of storage chambers in the refrigerator body, and a door that opens and closes the plurality of storage chambers. The partition plate is filled with a foam heat insulating material in a hollow portion inside thereof, and the partition plate has a surface plate, and a rib having a hook-shaped portion is provided on the inner surface of the surface plate, and the rib is foam heat insulating. It may be configured to be buried in the material.

With this configuration, the rib-shaped portion of the rib provided on the inner surface of the surface plate of the partition plate is mechanically coupled to the foam heat insulating material. For this reason, it can suppress that the surface plate of a partition plate peels from a foam heat insulating material. Thereby, the high quality refrigerator which does not have the floating deformation of a surface board etc. can be provided.

In addition, the refrigerator according to an example of the embodiment of the present invention is configured such that the refrigerator main body has an inner box and an outer box, and a foam heat insulating material is filled between the inner box and the outer box. In addition, a urethane filling port communicating between the inner box and the outer box of the refrigerator main body may be provided. Furthermore, the refrigerator according to an example of the embodiment of the present invention may have a plurality of ribs arranged in a direction intersecting the opening surface of the urethane filling port. Further, the rib may be configured to have a bridge shape.

And the foaming heat insulating material which flows in into a partition plate from a urethane filling port can be made to flow more reliably between the surface board inner surface of a partition plate, and a bridge-shaped rib, and can be solidified. Furthermore, when the rib is configured to have a bridge shape, the flange-shaped portion that mechanically couples with the foamed heat insulating material of the rib is a bridge shape, so the foamed heat insulating material that flows into the partition plate from the urethane filling port However, it becomes a structure which couple | bonds with a foam heat insulating material in the both ends of a bridge-shaped rib. For this reason, the mechanical coupling between the foam heat insulating material and the bridge-shaped rib is more reliable and strong. Therefore, it is possible to more reliably and strongly prevent the separation of the surface plate of the partition plate and the foam heat insulating material while improving the productivity by simultaneously filling the foam heat insulating material between the refrigerator main body and the partition plate.

The (first) thick wall portion 126 is a corner portion of the refrigerator main body 101 in both the (first) thick wall portion 126a on the side plate portion 101a side and the (first) thick wall portion 126b on the bottom plate portion 101b side. It is formed so as to be thicker than the wall thickness of the wall other than X. With such a configuration, the rigidity of the lower end of the side plate portion 101a of the refrigerator main body 101 having a high ratio of receiving the total weight of the refrigerator main body 101 is greatly improved by the (first) thick wall portions 126 (126a, 126b). Thereby, even if it keeps supporting the full load of the refrigerator main body 101 and the door 110 (110a, 110b) which increased in weight for a long period of time, it can prevent that the refrigerator main body 101 deform | transforms. In addition, the (first) thick wall portion 126 for increasing the rigidity of the refrigerator main body 101 is formed only in the corner portion X serving as a connecting portion between the lower side plate portion 101a and the bottom plate portion 101b of the refrigerator main body 101. Thereby, compared with the case where the wall thickness of the whole wall around the lowermost vegetable compartment 109 of the refrigerator main body 101 is set thick, the deformation | transformation prevention of the refrigerator main body 101 is realizable, without reducing a capacity | capacitance largely.

In particular, in the refrigerator main body 101 of the refrigerator 100 according to the present embodiment, the (first) thick wall portion 126b is provided not only on the side plate portion 101a side but also on the bottom plate portion 101b side. When the door 110a is opened and closed, the thick wall portion 126b acts as a strength member against the moment load in the twisting direction applied to the corner portion X which is a connecting portion between the side plate portion 101a and the bottom plate portion 101b of the refrigerator main body 101. . Therefore, compared with the case where only the (first) thick wall portion 126a is provided on the side plate portion 101a, the resistance against the load of the refrigerator main body 101 and the door 110 (110a, 110b) is improved, and the refrigerator main body 101 is more effectively produced. Can be prevented from being deformed.

As described above, in the refrigerator 100 of the present embodiment, it is possible to achieve both the securing of the capacity of the refrigerator main body 101 and the prevention of deformation at a high level.

Further, the refrigerator 100 of the present embodiment includes a side plate portion 101a on which the large door 110a is pivotally supported among the side plate portions 101a on which the double doors 110 (110a, 110b) of the refrigerator main body 101 are pivotally supported. You may have the thick wall part 127 (2nd) thicker than the wall thickness of the side plate part 101a by which the other small door 110b is pivotally supported.

Furthermore, in the refrigerator 100 of the present embodiment, a square frame portion R having a thick (second) thick wall portion 127a formed on one side may be formed in the refrigerator main body 101. Specifically, the square frame portion R is opposed to the (second) thick wall portion 127a, the

partition plates

121 and 22 provided above and below it, and the (second) thick wall portion 127a. And a thick wall portion 127b provided on the wall.

With such a configuration, even if the door 110 (110a, 110b) is formed of a glass plate or the like and has a large weight, the door 110 (110a, 110b) (particularly on the larger door 110a side). Can resist deformation against cantilever moment load.

That is, by increasing the wall thickness of the side plate portion 101a on the side where the larger door 110a is pivotally supported, the strength of the portion of the side plate portion 101a to which the cantilever moment load of the door 110a is directly applied is improved. Can do. As a result, the strength balance with the side plate portion 101a on the side on which the smaller door 110b is pivotally supported is obtained, so that it resists the deformation that tends to occur due to the difference in the left and right door moment loads. become. Furthermore, since the square frame portion R having the (second) thick wall portion 127a on one side is arranged in the portion directly below the door shaft support, the rigidity of the portion directly below the door shaft support of the refrigerator body 101 can be increased. . Thereby, even if it continues receiving the cantilever moment load of the door 110 (110a, 110b), it can resist the cantilever moment load of the door 110 (110a, 110b), and can suppress the deformation | transformation of the refrigerator main body 101. it can.

Therefore, even if it is used for a long time, deformation of the portion directly below the door shaft support of the refrigerator main body 101 can be prevented, and for example, no step is generated between the left and

right doors

110a and 110b of the double door 110, and reliability is improved. High refrigerator can be provided.

In the refrigerator 100 of the present embodiment, as described above, the (first) thick wall portion 126 (126a, 126b) is formed in the corner portion X that is a connecting portion between the side plate portion 101a and the bottom plate portion 101b. Has been. Furthermore, in the refrigerator 100 of the present embodiment, the (second) thick wall portion 127a has a (second) thick wall portion 127a having a thicker wall thickness than the other portions, provided on the side plate portion 101a of the door shaft support portion. May be provided on one side.

With such a configuration, the rigidity of the lower part of the refrigerator main body 101 having a high ratio of receiving the total weight of the refrigerator main body 101 and the portion directly below the door support portion that intensively supports the heavy load of the door 110 are increased. The entire refrigerator main body 101 can be made stronger. Thereby, even if it uses for a long period of time, a reliable refrigerator with few deformations can be obtained.

Moreover, in the refrigerator 100 of this Embodiment, the container provided in the step part 128 (128a, 128b) of the side-plate part 101a formed in the corner part X of the lowest part of the refrigerator main body 101 so that insertion / extraction in the vegetable compartment 109 is possible. A fixed rail 130 may be installed. With such a configuration, the fixed rail 130 becomes a strength member of the side plate portion 101a, and the rigidity can be further increased. Moreover, the container may be installed in a state of floating from the bottom of the vegetable compartment 109 using the (first) thick wall portion 126 (126a, 126b) provided to improve the rigidity of the refrigerator main body 101. As a result, the rail installation can be rationalized.

Moreover, in the refrigerator 100 of this Embodiment, the fixed rail 130 and the moving rail 129 may be provided in the level | step-difference part 128 (128a, 128b). With such a configuration, even if dew condensation water is generated on the bottom surface of the vegetable compartment 109 and accumulates, the fixed rail 130 and the movement rail 129 are immersed in the dew condensation water, so that It is possible to prevent the attached condensed water from freezing, and to prevent the occurrence of rust due to the attached condensed water. Therefore, a highly reliable refrigerator that avoids malfunction of the rail can be obtained.

In addition, the refrigerator 100 of the present embodiment is inclined such that the upper surface of the stepped portion 128b formed by the (first) thick wall portion 126b is lowered toward the front opening end of the vegetable compartment 109 with respect to the horizontal plane. May be formed. With such a configuration, when the container is pulled out, the bottom surface of the moving rail 129 can be prevented from being rubbed against the stepped portion 128b even if the container is lowered due to the weight of the container. Therefore, it is possible to prevent the appearance of the vegetable chamber 109 from being deteriorated due to scratches on the portion facing the opening.

On the other hand, the square frame portion R disposed in the portion directly below the door shaft support of the refrigerator main body 101 may be divided into the switching chamber 106 and the ice making chamber 107 by the vertical partition 125. With such a configuration, the rigidity of the square frame portion R itself can be improved, and deformation of the portion directly below the door shaft support can be effectively prevented. Moreover, the (second) thick wall portion 127a formed in the portion directly below the door shaft support is formed in the side plate portion 101a on the switching chamber 106 side having a wide opening. With such a configuration, it is possible to improve the opening strength of the switching chamber 106, which has a wide opening and tends to be weak, and the deformation of the refrigerator main body 101 can be more effectively suppressed.

Further, in the refrigerator 100 of the present embodiment, the vacuum heat insulating material 124 provided on the side plate portion 101a of the refrigerator main body 101 is in a position where it does not overlap with the (first) thick wall portion 126a in the lower portion of the side plate portion 101a. It may be provided only. Further, the corner portion X of the side plate portion 101a and the bottom plate portion 101b of the refrigerator main body 101 may be configured using only the foam heat insulating material 104 as a heat insulating material. That is, the corner portion X between the side plate portion 101a and the bottom plate portion 101b of the refrigerator main body 101 is filled with only the foam heat insulating material 104 having higher strength than the vacuum heat insulating material 124 as a heat insulating material (that is, having a vacuum heat insulating material). It may be configured). With such a configuration, the strength of the corner portion X becomes higher than when the vacuum heat insulating material 124 is interposed, and the deformation of the refrigerator main body 101 can be strongly prevented, and a refrigerator with higher reliability can be obtained. Can do.

Further, in the refrigerator 100 of the present embodiment, the corner portion X, which is a connecting portion between the side plate portion 101a and the bottom plate portion 101b of the lowermost storage chamber 109 of the refrigerator main body 101, is the corner portion X and the bottom plate portion of the side plate portion 101a. Both the corner parts X of 101b are provided with the 1st thick wall part 126 thicker than the wall thickness of the wall of other parts other than the corner part X. FIG.

With such a configuration, the rigidity of the lower end of the side plate portion 101a of the refrigerator main body 101 having a high ratio of receiving the total weight of the heavy refrigerator main body 101 can be greatly improved. Thereby, it can prevent that the lower end of the side-plate part 101a of the refrigerator main body 101 deform | transforms even if it continues supporting the weight of the refrigerator main body 101 and the

doors

110, 111, 112, 113, 114 for a long period of time. And the wall thickness of the corner part X used as the connection part of the side plate part 101a of the lowermost storage chamber 109 of the refrigerator main body 101 and the bottom plate part 101b is each of the lower side plate part 101a and the bottom plate part 101b of the refrigerator main body 101. Since only the corner portion X is set to be thick, it is possible to prevent deformation without greatly reducing the capacity of the refrigerator 100 as compared with the case where the wall thickness of the entire wall around the lowermost storage chamber 109 of the refrigerator body 101 is set to be thick. Can be realized.

In addition, in the refrigerator 100 of the present embodiment, one of the

doors

110, 111, 112, 113, 114 is constituted by a double door 110, and one of the double doors 110 has a door 110a having a larger size than the other. You may have. In this case, the side plate portion 101a of the refrigerator main body 101 on the side where the large door 110a is pivotally supported has a wall thickness that is larger than the wall thickness of the side plate portion 101a of the refrigerator main body 101 on the side where the other small door 101b is pivotally supported. It is desirable to provide a thick second wall portion 127a.

In addition, the refrigerator 100 according to the present embodiment has a square frame portion R having

partition plates

With such a configuration, the strength of the side plate portion 101a of the refrigerator main body 101 to which the cantilever moment load of the large door 110a is directly applied is increased by the second thick wall portion 127a. Moreover, since the rectangular frame portion R having the second thick wall portion 127a as one side is disposed in the refrigerator main body 101, the rigidity of the portion directly below the shaft support of the door 110 of the refrigerator main body 101 is enhanced. Thereby, even if the side plate part 101a of the refrigerator main body 101 continues to receive the cantilever moment load of the door 110a having a large door 110, it can resist the cantilever moment load of the door 110 and suppresses deformation of the refrigerator main body 101. can do. Therefore, no step is generated between the left and right doors of the double door 110 even when used for a long time, and a highly reliable refrigerator can be obtained.

Further, in the refrigerator 100 of the present embodiment, the corner portion X, which is a connecting portion between the side plate portion 101a and the bottom plate portion 101b of the lowermost storage chamber 109 of the refrigerator main body 101, is the corner portion X and the bottom plate portion of the side plate portion 101a.

doors

110, 111, 112, 113, 114 is You may comprise the double doors 110. In this case, the double door 110 may have a door 110a having a larger size than the other and a small door 110b on the other. In this case, the side plate portion 101a on the side where the large door 110a is pivotally provided includes a second thick wall portion 127a which is thicker than the wall thickness of the side plate portion 101a on the side where the other small door 101b is pivotally supported. In addition, a rectangular frame portion R having a

partition plate

121, 122 disposed above and below the second thick wall portion 127a and the second thick wall portion 127a on the side is disposed in the refrigerator main body 101. Yes.

With such a configuration, the effect of providing the first thick wall portion 126 described above and the effect of providing the second thick wall portion 127a are combined, and the door 110 that supports the load of the door 110 in a concentrated manner is supported. The rigidity of each of the lower part of the refrigerator main body 101 and the lower part of the refrigerator main body 101 having a high ratio of receiving the total weight of the refrigerator main body 101 can be increased. Thereby, the whole refrigerator main body 101 can be made tougher, and even if it has been used for a long time, it can be made highly reliable with little deformation.

Further, the refrigerator 100 of the present embodiment is a container provided in a stepped portion 128 of the side plate portion 101a formed by the first thick wall portion 126 having a thick wall portion of the corner portion X so as to be freely put in and out of the storage chamber 109. The moving rail 129 may be installed.

With such a configuration, the container can be installed in a state of floating from the bottom surface of the storage chamber 109 using the first thick wall portion 126, so that the installation of the moving rail 129 can be rationalized. Furthermore, even if condensed water is generated and accumulated on the bottom surface of the storage chamber 109, the moving rail 129 is immersed in the condensed water, so that the condensed water adhering to the moving rail 129 is frozen or the moving rail 129 is rusted. It is possible to prevent the occurrence of defects. Therefore, a more reliable refrigerator can be obtained.

In the refrigerator 100 of the present embodiment, the upper surface (stepped portion 128a) of the stepped portion 128 of the bottom plate portion 101b formed by the first thick walled portion 126 having the thick wall thickness of the corner portion X is in a horizontal plane. Further, it may be formed to be inclined so as to become lower toward the opening end of the storage chamber 109.

Such a configuration can prevent the bottom surface of the container from rubbing against the top surface of the stepped portion 128 even when the container is pulled down due to the weight of the container when the container is pulled out. Accordingly, it is possible to prevent the appearance of the storage chamber 109 from being deteriorated due to scratches on the portion facing the opening.

Further, in the refrigerator 100 of the present embodiment, the square frame portion R is divided into two left and

right storage chambers

With such a configuration, since the square frame portion R is divided into the two

storage chambers

106 and 107, the rigidity of the square frame portion R itself can be further improved. At the same time, it is possible to improve the opening strength of the storage chamber 106 which has a wide opening and tends to be weak. Thereby, the deformation | transformation of the refrigerator main body 101 can be suppressed further effectively, and reliability can be improved significantly.

The corner portion X between the side plate portion 101a and the bottom plate portion 101b of the refrigerator main body 101 is configured using only the foam heat insulating material 104 as a heat insulating material.

With such a configuration, the corner portion X of the side plate portion 101a and the bottom plate portion 101b of the refrigerator main body 101 is filled with only the foam heat insulating material 104 having higher strength than the vacuum heat insulating material 124 as the heat insulating material. Is higher than when the vacuum heat insulating material 124 is interposed. Therefore, the deformation of the refrigerator main body 101 can be strongly prevented and the reliability can be further increased.

In addition, as shown in FIG.1 and FIG.5, the vacuum heat insulating material 124 is installed in the refrigerator main body 101 in this Embodiment between the outer box 102 and the inner box 103 which comprise this. By providing the vacuum heat insulating material 124 and the foam heat insulating material 104, the wall thickness of the refrigerator main body 101 can be reduced as a whole as compared with the case where only the foam heat insulating material 104 is used, and the capacity can be increased. it can.

Furthermore, as shown in FIG. 5, the refrigerator main body 101 in the present embodiment includes a switching chamber 106 disposed below the refrigerator compartment 105, an ice making chamber 107, a freezer compartment 108, and vegetables arranged in parallel therewith. The wall thicknesses T2, T3, T4, and T5 of the chamber 109 are set to be thicker than the wall thickness T1 of the refrigerator compartment 105. In addition, in the storage chamber disposed below the refrigerator compartment 105 in which the wall thickness is set to be thicker than the wall thickness T1 of the refrigerator compartment 105, the switching chamber 106 having a low cooling temperature zone that requires strong heat insulation and the switching chamber 106 The wall thicknesses T2, T3, and T4 of the ice making chamber 107 and the freezing chamber 108 arranged side by side are set to be thicker than the wall thickness T5 of the vegetable chamber 109 where the cooling temperature zone is set to be relatively high. It is desirable. In the present embodiment, the wall thicknesses T1, T2, T3, T4, and T5 of the refrigerator main body 101 have a relationship of T2> T3 = T4> T5> T1.

Moreover, the refrigerator main body 101 of this Embodiment has the corner part X used as the connection part of the side plate part 101a and the bottom plate part 101b of the vegetable compartment 109 which is a storage room arrange | positioned at the lowest part of the refrigerator main body 101, FIG. As shown in FIG. 5, both the corner portion X of the side plate portion 101a and the corner portion X of the bottom plate portion 101b have a thick (first) thick wall portion 126 that is thicker than the wall thickness of the wall other than the corner portion X. .

About the refrigerator 100 comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

The refrigerator 100 according to the present embodiment includes an ice making chamber 107 and a switching chamber 106 that are divided into two chambers, a left chamber and a right chamber, in a substantially central portion between the refrigerator chamber 105 and the freezer chamber 108 of the refrigerator main body 101. Has been placed. Further, the upper partition plate 121 and the lower partition plate 122 constituting the ice making chamber 107 and the switching chamber 106 are connected by a vertical partition 125. With such a configuration, the upper partition plate 121 and the lower partition plate 122 reinforce each other against torsional force due to the connection by the vertical partition 125. Moreover, even if the refrigerator main body 101 is expanded in the horizontal width direction and the horizontal width dimensions of the upper partition plate 121 and the lower partition plate 122 constituting the ice making chamber 107 and the switching chamber 106 are increased, the horizontal width is increased. Since it is divided and connected by the vertical partition 125, the function as a strength member of the storage chamber (the ice making chamber 107 and the switching chamber 106) having the upper partition plate 121 and the lower partition plate 122 is improved. Thereby, the rigidity of the refrigerator main body 101 can be greatly improved.

Therefore, even if a twisting force or the like is applied to the refrigerator main body 101 when the door 110, particularly the large door 110a is opened or closed, the door 110 (110a, 110b formed of a heavy material such as a glass plate) can be resisted. ), And the deformation of the refrigerator main body 101 can be strongly suppressed.

Further, even if the refrigerator main body 101 is enlarged in the width direction and the left and right width dimensions of the upper partition plate 121 and the lower partition plate 122 are increased, the upper partition plate 121 and the lower partition plate 122 are Since the upper partition plate 121 and the lower partition plate 122 are connected in the direction by the vertical partition 125, it is possible to prevent the upper partition plate 121 and the lower partition plate 122 from being deformed into a bellows shape. Further, the flatness of the upper partition plate 121 and the lower partition plate 122 is increased, and a high-quality refrigerator with high dimensional accuracy is obtained.

The upper partition plate 121 and the lower partition plate 122 are particularly easily bent and deformed during resin molding. For example, the upper partition plate 121 is deformed upward, the lower partition plate 122 is deformed downward, and the upper partition plate 121 and the lower partition plate 122 are formed in a bellows shape (for example, a central portion in the left-right direction). May swell more than the left and right ends.

However, in the present embodiment, the upper partition plate 121 and the lower partition plate 122 having a bellows shape are corrected for deformation by the connection between the upper vertical partition 125a and the lower vertical partition 125b. The flatness of the upper partition plate 121 and the lower partition plate 122 is improved, and the dimensional accuracy can be increased.

In the present embodiment, the upper partition plate 121 and the lower partition plate 122 are connected such that the hook portion 225 of the lower vertical partition member 125b is fitted into the recess 226 provided on the upper vertical partition member 125a. Is going by. Therefore, compared with the case where the vertical partition body upper portion 125a and the vertical partition body lower portion 125b are connected by screws, the connecting operation can be performed easily and quickly, and the productivity can be increased.

Moreover, the upper vertical partition 125 a constituting the vertical partition 125 is integrally formed with the upper partition plate 121, and the lower vertical partition 125 b is integrally formed with the lower partition plate 122. Therefore, the number of parts can be reduced, and combined with the improvement in productivity by shortening the work time, it is possible to provide a refrigerator at low cost.

Moreover, since the vertical partition 125 is divided and formed by the vertical partition upper 125a and the vertical partition lower 125b, the vertical dimension of at least one of the vertical partition upper 125a and the vertical partition lower 125b can be shortened. it can. Therefore, it is possible to prevent the vertical partition 125 from being deformed, which tends to occur when the vertical partition 125 is provided on the upper partition plate 121 and the lower partition plate 122, and to prevent the upper partition plate 121 and the lower partition plate from being deformed. It is possible to prevent or minimize deformation such as bending of the partition plate 122 itself. Therefore, the flatness of the upper partition plate 121 and the lower partition plate 122 can be further increased to increase the dimensional accuracy.

Further, as shown in FIG. 14, the fitting connection portion between the vertical partition upper 125a and the vertical partition lower 125b has a shape in which the front side of the recess 226 provided on the vertical partition 125a is open. Therefore, it is possible to simply fit and connect the upper vertical partition 125a and the lower vertical partition 125b simply by pushing the hook portion 225 provided on the lower vertical partition 125b from the front to the rear. Moreover, the hook portion 225 can be pushed into the concave portion 226 at the same time as the lower partition plate 122 is mounted, and the assemblability can be improved and the cost can be reduced.

On the other hand, in the left and right storage chambers formed by the upper partition plate 121 and the lower partition plate 122, that is, the switching chamber 106 and the ice making chamber 107, one switching chamber 106 has a larger volume than the other ice making chamber 107. The other ice making chamber 107 is formed on the side plate on the side of the switching chamber 106 which is formed so as to have a smaller volume than the switching chamber 106 and has a large opening and a wide opening (second). A thick wall portion 127a is formed. With such a configuration, it is possible to increase the rigidity of the switching chamber 106, which has a large opening and tends to be weak, and the rigidity of the refrigerator body 101 can be further increased.

In addition, the large door 110a of the double doors of the refrigerating chamber 105 disposed above the switching chamber 106 and the ice making chamber 107 divided into two chambers on the left and right is the (second) thick wall portion of the switching chamber 106. It is pivotally supported by 127a. Accordingly, it is possible to increase the strength of the portion where the cantilever moment load of the large door 110a is directly applied, and even if the door 110a is made of a heavy material such as a glass plate and is increased in weight, the refrigerator body 101 can be effectively deformed. Can be suppressed.

Further, in the present embodiment, the refrigerator main body 101 is set such that the wall thickness of the side plate portion 101a of the storage room disposed below the refrigerator compartment 105 is thick (T2, T3, T4, T5> T1). With such a configuration, the rigidity of the lower portion of the refrigerator main body 101 that increases the ratio of receiving the load of the refrigerator main body 101 and the door 110 is increased. Thereby, even if the refrigerator main body 101 is enlarged or the door is formed of a glass plate or the like, and the refrigerator is increased in weight, deformation of the refrigerator main body 101 can be suppressed to a minimum.

In particular, the corner portion X, which is a connecting portion between the side plate portion 101a and the bottom plate portion 101b of the lowermost vegetable compartment 109 of the refrigerator main body 101, has a corner at both the corner portion of the side plate portion 101a and the corner portion X of the bottom plate portion 101b. It has a (first) thick wall portion 126 that is thicker than the wall thickness of other portions other than the portion X. With such a configuration, the rigidity of the corner portion X is greatly improved, and the refrigerator main body 101 can be effectively prevented from being deformed even if the loads of the refrigerator main body 101 and the door 110 are supported for a long time.

In addition, the (first) thick wall portion 126 for increasing the rigidity of the refrigerator main body 101 is formed only in the corner portion X serving as a connection portion between the side plate portion 101a and the bottom plate portion 101b at the lower portion of the refrigerator main body 101. Accordingly, it is possible to prevent deformation of the refrigerator body 101 without greatly reducing the capacity of the storage room at the bottom of the refrigerator body 101 (in this embodiment, the vegetable room 109).

In the present embodiment, the refrigerator main body 101 is provided with the (first) thick wall portion 126b not only on the side plate portion 101a having the above-described wall thickness but also on the bottom plate portion 101b side. With such a configuration, when the (first) thick wall portion 126b is opened and closed, the twist direction applied to the corner portion X which is a connecting portion between the side plate portion 101a and the bottom plate portion 101b of the refrigerator main body 101. It acts as a strength member against the moment load. Therefore, compared with the case where the (first) thick wall portion 126a is provided only on the side plate portion 101a, the resistance against the full load of the refrigerator main body 101 and the door 110 is improved, and the main body of the refrigerator main body 101 is extended over a longer period. Deformation can be prevented.

As mentioned above, although the refrigerator by an example of embodiment of this invention was demonstrated using the example, this invention is not limited to this.

For example, in the present embodiment, the vertical partition 125 is divided into an upper vertical partition 125a and a lower vertical partition 125b. However, the upper partition plate 121 or the lower partition plate 122 may be integrally formed as one of the upper and lower sides, that is, the vertical partition body 125a or the vertical partition body 125b as the vertical partition body 125, Alternatively, it may be formed as a separate body and engaged with or joined to the upper partition plate 121 or the lower partition plate 122.

Further, the storage chamber provided by dividing the upper partition plate 121 and the lower partition plate 122 into two chambers by the vertical partition 125 is not limited to the ice making chamber 107 and the switching chamber 106. For example, a storage room having other functions such as a freezer room and a freezer room can be used, and it can be divided into two or more rooms.

A hinge member 115 pivotally supports the door 110 (110a, 110b) of the refrigerator compartment formed above the partition plate 121.

Here, in the partition plate 121, as shown in FIGS. 31, 32A and 32B, ribs 434 are integrally provided on the inner surface of the upper plate 121a serving as the bottom surface of the refrigerator compartment 105. As shown in FIG. 29, the rib 434 has a hook-like shape that can be buried in the foam heat insulating material 104 filled in the hollow portion of the partition plate 121 and mechanically coupled thereto. In the present embodiment, the rib 434 is formed in a bridge shape having hook-shaped portions W at both ends.

As shown in FIGS. 31, 32A, and 32B, the rib 434 has a rib 434a provided at the front portion of the partition plate 121 and a rib 434b provided at the rear portion. A plurality of ribs 434a and ribs 434b are also arranged in the left-right direction. In the present embodiment, the rib 434a provided at the front portion is formed such that the front-rear length L thereof is longer than the front-rear length l of the rib 434b provided at the rear portion.

Further, a plurality of

ribs

434a and 434b are arranged in a direction intersecting the opening surface of the urethane filling port 435 provided in the front portion of the side plate 430 of the upper plate 121a (see FIG. 31).

Next, the effect of the refrigerator 100 of the present embodiment configured as described above will be described.

First, the filling of the partition plate 121 with urethane will be described. In refrigerator 100 of the present embodiment, as shown in FIG. 30, upper plate 121a and lower plate 121b of partition plate 121 are combined to form hollow partition plate 121 in advance, and partition plate 121 is the main body of the refrigerator. 101. In this state, the foam heat insulating material 104 is filled between the inner box 103 and the outer box 102 of the refrigerator main body 101.

Thereby, the foam heat insulating material 104 flows into the hollow part of the partition plate 121 from the urethane discharge port (not shown) between the inner box 103 and the outer box 102 of the refrigerator main body 101 through the urethane filling port 435. The partition plate 121 is integrally formed with the refrigerator main body 101.

In the partition plate 121 of the refrigerator 100 configured as described above, when the bridge-shaped rib 434 is formed on the inner surface of the upper plate 121a, the bridge-shaped rib 434 is formed in the foam heat insulating material 104 of the partition plate 121. Buried. With such a configuration, the rib 434 is mechanically coupled to the foam heat insulating material 104. That is, the foam heat insulating material 104 flows and solidifies between the bridge-shaped portion of the rib 434 and the upper plate 121a, and the foam heat insulating material 104 and the hook-shaped portions W at both ends of the bridge-shaped rib 434 are mechanically coupled. . With such a configuration, it is possible to more reliably suppress the upper plate 121a of the partition plate 121 from being separated from the foam heat insulating material 104.

In particular, when the rib 434 has a bridge shape, the rib 434 is connected to the upper plate 121a of the partition plate 121 at two hook-shaped portions W at both ends of the bridge shape. Therefore, since the mechanical coupling between the foam heat insulating material 104 and the rib 434 becomes stronger, the peeling prevention effect can be enhanced. As the shape having the hook-shaped portion W that can be mechanically coupled to the foam heat insulating material 104, a substantially L-shaped shape is conceivable. In the case of the substantially L-shaped shape, the shape is mechanically coupled to the foam heat insulating material 104. Since the hook-shaped portion W has a single cantilever shape, the strength is slightly inferior. However, since the rib 434 is configured to have a bridge shape as in the present embodiment, the hook-shaped portion W mechanically coupled to the foam heat insulating material 104 becomes two places at both ends of the bridge shape. Since it has a doubly supported beam shape, the mechanical coupling force becomes strong.

Further, in the present embodiment, the ribs 434 have a bridge shape, and a plurality of rows are provided so as to intersect with the opening surfaces of the urethane filling ports 435 provided on the front left and right of the partition plate 121. With such a configuration, the foam heat insulating material 104 that flows into the hollow portion of the partition plate 121 from the urethane filling port 435 surely flows between the inner surface of the upper plate 121a of the partition plate 121 and the bridge-shaped portion of the rib 434 to be filled and solidified. To do. Therefore, the mechanical coupling between the foam heat insulating material 104 and the bridge-shaped rib 434 is more reliable, and the separation between the upper plate 121a of the partition plate 121 and the foam heat insulating material 104 can be more reliably suppressed.

Furthermore, since the foam insulating material 104 can be filled in the partition plate 121 simultaneously by filling the refrigerator main body 101 with the foam heat insulating material 104, the upper plate 121a of the partition plate 121 and the foam heat insulating material can be improved while increasing the productivity. 104 can be prevented from being peeled off.

Also, a plurality of bridge-shaped ribs 434 are arranged in the left-right direction at the front part and the rear part of the partition plate 121, respectively. At the same time, the rib 434a provided at the front part is formed such that the front-rear length L thereof is longer than the front-rear length l of the rib 434b provided at the rear part. With such a configuration, the mechanical connection between the upper plate 121a and the bridge-shaped rib 434 at the front portion of the partition plate 121 can be more strongly performed over the entire partition plate.

Therefore, it is possible to effectively prevent peeling at the front portion of the partition plate 121 that is easily noticeable by the user when the door 110 is opened. In particular, in the present embodiment, the rear part of the partition plate 121 is covered with the partial chamber 105a, and only the front part is configured to be visible to the user when the door is opened. Can be improved more effectively.

Furthermore, the rib 434aa located in the vicinity of the door shaft support portion of the partition plate 121 is provided closer to the front end surface of the partition plate 121 than the rib 434ab closer to the center portion. With such a configuration, the upper plate 121a on the left and right portions of the partition plate 121 on which the door 110 is pivotally supported and the rib 434 are mechanically coupled on the front end surface side.

Therefore, it is possible to effectively suppress the separation between the upper plate 121a in the vicinity of the shaft support portions at both ends of the partition plate 121 that is easily deformed into the front-down state due to the door load and the foam heat insulating material 104.

In addition, the rib 434ab near the center other than the rib 434aa located in the vicinity of the door shaft support portion of the partition plate 121 is positioned at a substantially central portion in the front-rear direction of the partition plate 121. With such a configuration, it is possible to ensure the mechanical coupling between the upper plate 121a and the foam heat insulating material 104 in the substantially central portion of the partition plate 121, and thus ensure a good mechanical connection over the entire surface of the partition plate 121. be able to.

Furthermore, in the present embodiment, as shown in FIG. 33, reinforcing metal fittings 230 are provided on the front end surface that serves as the left and right shaft support portions of the partition plate 121. Further, the end portion 230b of the reinforcing metal fitting 230 is provided so as to extend to the side plate portion front end surface 101aa of the refrigerator main body 101, and is fixed to the side plate portion front end surface 101aa with screws or the like. With such a configuration, the front lowering deformation of the shaft support portion of the partition plate 121 can be reliably prevented by the reinforcing metal fitting 230, and the peeling between the upper plate 121a in the vicinity of the shaft support portion of the partition plate 121 and the foamed heat insulating material 104 can be further prevented. It can be effectively suppressed.

That is, since the end 230b of the reinforcing metal fitting 230 is extended and fixed to the side plate front end surface 101aa of the refrigerator main body 101, the load of the door 110 applied to the door shaft support portion of the partition plate 121 is fixed by the reinforcing metal fitting 230. The refrigerator body 101 is also supported by the side plate front end face 101aa. Therefore, it is possible to strongly prevent the front end surface of the partition plate 121 from being lowered downward.

Accordingly, the rib 434aa located in the vicinity of the door shaft support portion is more effectively combined with the effect provided by the portion closer to the front end surface of the partition plate 121 than the rib 434ab near the other central portion, and more effectively the partition plate. It is possible to prevent peeling between the upper plate 121a near the shaft support portion 121 and the foam heat insulating material 104.
