[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a freezer-refrigerator in which a refrigerating compartment and a refrigerating compartment are formed by partitioning a heat insulating box, and more particularly, the structure of a portion where the partition is attached to a wall surface of the heat insulating box. Regarding

[0002]

2. Description of the Related Art As a conventional refrigerator-freezer, as shown in FIG. 10, a partition 42 having an L-shaped front surface is provided inside a heat insulating box 41.
It is known that a freezer compartment 43 is formed in one corner of the refrigerator and a refrigerating compartment 44 is formed in the remaining portion by attaching the. The partition body 42 has a structure in which a heat insulating material 47 is filled between the two panels 45 and 46 to be integrated, and the upper end surface 42a of the partition body 42 and the back side are orthogonal to each other. 4 of the end faces 42b and 42c and the right end face 42d
The two end surfaces are attached to the ceiling surface, the back surface and the right side surface of the inner box 48 of the heat insulating box 41, respectively.

The detailed mounting structure is as follows.
For example, taking the upper end surface 42a of the partition 42 as an example, as shown in FIG. 11, the edge of the panel 45 on the refrigerating compartment 44 side of the two panels 45, 46 is the refrigerating compartment 44 side. By being bent at a right angle to, a mounting seat 50 provided with an insertion hole for the screw 49 is formed, and the end edge of the panel 46 on the freezer compartment 43 side is one step lower than the panel 45 on the refrigerating compartment 44 side. It is bent at a right angle toward the refrigerating compartment 44 side, and a heat insulating material 47 is filled between both panels 45 and 46.

A seal body 51 made of moltoprene, styrene, or the like is provided on the step portion of the end surface 42a of the partition body 42.
The mounting seat 50 is fixed to the ceiling surface by placing the mounting seat 50 against the ceiling surface of the inner box 48 of the heat insulating box body 1 and tightening the screw 49 while sandwiching the seal body 51. . Here, the seal body 51 is for absorbing the tolerance of the mounting portion to prevent air leakage between the freezer compartment 43 and the refrigerating compartment 44. The other three end faces 42b of the partition body 42
Up to 42d also have the same mounting structure as above.

[0005]

That is, in each of the mounting end faces 42a to 42d of the partition body 42, since the mounting seat 50 is provided on the refrigerating chamber 44 side, the seal body 51 is exposed on the freezing chamber 43 side. It is installed. Here, for example, as when defrosting the freezer compartment 43,
When the temperature inside the freezer compartment 43 changes and the air inside expands or contracts, the air circulation occurs despite the presence of the sealing body 51, which is called breathing action, and particularly from the refrigerating compartment 44 to the freezer compartment 43. Moisture in the inflowing air may freeze on the surface of the seal body 51 exposed on the freezing chamber 43 side. Further, since the exposed seal body 51 also impairs the aesthetics of the freezer compartment 43, in addition to preventing the above freezing, the exposed surface of the seal body 51 is provided with caulking 52 of silicon or the like. Measures were being taken. However, caulking takes a great deal of work, and the appearance is not always good-looking.

As another problem other than the above, the partition 42
When the mounting seats 50 of the respective end faces 42a to 42d are screwed, the end face 42c of the horizontal portion on the back side and the end face 42d on the right side of the end face 42a to 42d go into the narrow portion of the refrigerating chamber 44 below the freezing chamber 43. Since it had to be screwed in, there was a drawback that the work was difficult. The present invention has been completed based on the above circumstances, and an object of the present invention is to provide a partition body mounting structure in a refrigerator-freezer, which is capable of mainly performing the mounting work easily. Is.

[0007]

As a means for achieving the above object, the invention of claim 1 is a freezer-refrigerator in which a freezing compartment and a refrigerating compartment are divided into compartments by providing a partition in the heat insulating box. The partition body is formed by filling a heat insulating material between two panels, and an end surface of the partition body is attached to a wall surface of the heat insulating box body with a seal body interposed therebetween. The end face is characterized in that a mounting seat for the wall surface of the heat insulating box is formed by bending the edge of the panel on the freezer compartment toward the freezer compartment.

The invention of claim 2 is characterized in that, in the invention of claim 1, the bent portion of the mounting seat is formed in a curved shape. According to a third aspect of the present invention, in the first or second aspect of the present invention, a hygroscopic material is interposed between the seal body and the wall surface of the heat insulation box body in a state of being exposed to the refrigerating compartment side. It has a feature in that it has a structure.

[0009]

According to the first aspect of the present invention, since the mounting seat is provided on the panel on the freezer compartment side, the seal body interposed between the end face of the partition body and the wall surface of the heat insulating box body is on the refrigerating compartment side. Can be exposed to. Further, the work of fixing the mounting seat with a fastener such as a screw can be performed from the freezer compartment side. In the invention of claim 2, since the bent portion of the mounting seat is formed into a curved surface, it is easy to clean that portion.

The operation of the invention of claim 3 is as follows. At the inner wall of the heat insulating box where the end face of the partition is attached, especially at the boundary with the partition on the refrigerating compartment side, cooling may occur due to the conduction of cold air from the freezer compartment, causing condensation. There is. In this respect, according to the third aspect of the invention, since the moisture absorbent is provided in the portion where dew condensation easily occurs, it is possible to prevent moisture from being absorbed by the moisture absorbent to cause dew condensation.

[0011]

According to the first aspect of the present invention, since the seal body is exposed to the refrigerating chamber side, there is no possibility of icing on the seal body, so that caulking becomes unnecessary and the mounting seat Since the installation can be done from the freezer side, the work becomes easier, and the work of installing the partition can be done easily. In addition, since caulking is not required, the appearance can be improved. There is.

According to the second aspect of the present invention, in addition to the above effects, the corner portion in the freezing compartment can be easily cleaned, so that the interior of the freezing compartment can be made cleaner. According to the invention of claim 3, in addition to the above-mentioned effect, there is an effect that it is possible to reliably prevent dew condensation from occurring at the boundary between the inner wall of the refrigerating compartment and the partition.

[0013]

Embodiments of the present invention will be described below with reference to the accompanying drawings. <First Embodiment> FIGS. 1 to 4 show a first embodiment of the present invention. In FIG. 1, reference numeral 1 is a heat insulating box, which is filled with a heat insulating material between the outer box 2 and the inner box 3 and is formed in a rectangular parallelepiped shape with the front surface opened as a whole. In the upper right portion of the heat insulating box 1 when viewed from the front, the partition body 5 having an L-shaped front shape as described later in detail (see FIG. 2).
Is attached, so that a freezing chamber 6 is formed in the upper right corner and a refrigerating chamber 7 is formed in the remaining portion. A front frame 8 assembled in a cross shape is attached to the front opening of the heat insulating box 1 so that a part of the front frame 8 covers the front end surface of the partition body 5. A heat insulating door (not shown) is attached to the opening so as to be openable and closable.

Next, the structure of the partition 5 will be described. As shown in FIG. 2, the partition body 5 is provided with two inner and outer metal panels 10 and 11 each bent into an L-shape, and both panels 10 and 11 are arranged at regular intervals. Then, the heat insulating material 12 is filled between them to form an integrated structure. The inner panel 10 (hereinafter referred to as the inner panel) of the two panels 10 and 11 faces the freezer compartment 6, and the outer panel 11 (hereinafter referred to as the outer panel) faces the refrigerating compartment 7. To be done. Also, the inner panel 10
The bent portion 13 of is bent with a roundness. The end surface 5a on the upper side of the partition body 5, the two end surfaces 5b and 5c on the inner side, which are orthogonal to each other, and the end surface 5d on the right side,
It is adapted to be attached to the ceiling surface 3a, the back surface 3b and the right side surface 3c of the inner box 3 of the heat insulating box 1, respectively.

Next, the structure of the mounting end faces 5a to 5d of the heat insulating box 1 of the partition 5 to the inner box 3 will be described in detail. First, at the upper end surface 5a attached to the ceiling surface 3a of the inner box 3, as shown in FIG. 3, the end edge of the inner panel 10 is bent inward at a right angle toward the inside (the freezing compartment 6 side), and The mounting seat 14 is formed by. Insertion holes for a plurality of screws 15 are formed in the mounting seat 14 at intervals in the length direction, and the bent portion 17 of the mounting seat 14 is bent with a particular roundness. The edge of one outer panel 11 is located at a position one step lower than the edge of the inner panel 10, and the edge is bent inward at a right angle to form a contact surface 20 of the seal body 19. The heat insulating material 12 described above is filled up to a position flush with the contact surface 20. Therefore, the above-described mounting seat 14 and the contact surface 2
0 and the end surface of the heat insulating material 12 have a step, and the seal body 19 is provided on the upper surface of the contact surface 20 and the end surface of the heat insulating material 12 over the entire length. The seal body 19 is made of moltoprene, styrene, or the like, and is formed in a band shape having a thickness slightly larger than the step size.

Further, the structure of the two end surfaces 5b and 5c on the back side which are applied to the back surface 3b of the inner box 3 of the heat insulating box 1 is formed similarly to the above-mentioned upper end surface 5a. Repeatingly, the edge of the inner panel 10 is rounded inward and bent at a right angle to form the mounting seat 14, and the edge of the outer panel 11 is formed.
The contact surface 20 is formed by being bent at a right angle inward from a position retracted by a certain size from the end edge of the seal member 19, and the seal body 19 is interposed in the step portion.

At the remaining right end surface 5d, as shown in FIG. 4, the end edge of the inner panel 10 is bent so as to be bent inward in an arc shape, and the mounting seat is not formed. In addition, the edge of the outer panel 11 is bent at a right angle inward from a position retracted by a certain size, so that the contact surface 20
Is formed, and the seal body 19 is similarly interposed at the step portion. As described above, the right end surface 5d is not provided with a mounting seat, and instead, the angled bracket 2 can be fixed to the right side surface 3c of the inner box 3 with the screw 25.
4 is provided, and the right end surface 5d is received by the bracket 24, and the screw 2 is provided between the bracket 24 and the outer panel 11.
It is fixed by stopping at 5.

In addition, on the two end surfaces 5e and 5f on the front side of the partition body 5 which are orthogonal to each other, the inner and outer panels 10 and 11 are formed.
End edges are bent at right angles in a direction in which they face each other on the same surface, and the front frame 8 is attached to the front surfaces of the respective end surfaces 5e and 5f.

Next, a method of mounting the partition body 5 having the above structure will be described. As shown in FIG. 3, the upper end surface 5a and the inner two end surfaces 5b and 5c are provided with seal bodies 19 respectively at the step portions, and the mounting seats 14 are sandwiched with the seal bodies 19 interposed therebetween. Ceiling surface 3a and back surface 3b of 3
Then, the end faces 5a to 5c are fixed by screwing the screws 15 into the inner box 3 through the insertion holes formed in the mounting seat 14.

When the right end surface 5d is attached, as shown in FIG.
As shown in, an angled bracket 24 is attached to the right side surface 3c of the inner box 3 by screwing. And
The inner panel 1 is sandwiched by the seal body 19 interposed in the step portion.
The arc-shaped portion 22 having the edge of 0 is placed on the horizontal portion 24a of the bracket 24 with the right side surface 3c of the inner box 3 being contacted. Then, the bracket 24 is fixed by screwing it into the outer panel 11 through the screw 25 from the lower surface side of the horizontal portion 24a.

The reason why the inner panel 10 is not provided with the mounting seat only on the right end surface 5d as described above is as follows. That is, if a mounting seat is provided and screwing is to be performed, it is difficult for a general right-handed worker to operate a screwing driver. In that respect, if the bracket 24 is used for the attachment as in the present embodiment, the driver is mounted on the horizontal portion 24 of the bracket 24 when screwed.
Since the operation can be performed from the lower surface side of "a", the screwing work becomes simple. In addition, at the right end face 5d, the seal body 1
Since it is not screwed in the direction in which the inner panel 9 is crushed, it is desirable to apply caulking 27 of silicon or the like along the edge of the inner panel 10 in order to achieve a more perfect sealing property.

As described above, according to this embodiment, the seal body 19 provided on each of the end surfaces 5a to 5d of the partition body 5 is blocked by the mounting seat 14 or the arc-shaped portion 22 of the inner panel 10 and frozen. Since it is not exposed to the chamber 6 side and is exposed only to the refrigerating chamber 7 side, there is no risk of ice formation on the seal body 19, and it is not necessary to perform caulking to prevent it. However, the caulking 27 is required on the right end surface 5d where the mounting seat is not provided, but since the caulking 27 is required only at one place, the burden of caulking work is greatly reduced. Further, since the mounting seat 14 can be screwed from the freezer compartment 6 side, the work is facilitated, so that the mounting work of the partition body 5 can be easily performed. In addition, it is possible to prevent the appearance from being deteriorated as much as possible by performing the caulking at one place as described above. Also,
Since the boundary between the freezing compartment 6 and the partition 5 and the bent portion 13 of the inner panel 10 of the partition 5, that is, the corner of the freezing compartment 6 is formed with a rounded shape, cleaning of that portion is performed. It becomes easier and the inside of the freezer compartment 6 can be kept clean.

<Second Embodiment> FIGS. 5 and 6 show a second embodiment of the present invention. In this embodiment, an improvement is added to the structure of the seal body interposed on the mounting end surface of the partition body 5, particularly on the end surfaces 5a to 5c provided with the mounting seats 14. The seal body 30 of the present embodiment is made of soft rubber, and as shown in FIG. 5, the inner panel 10 and the outer panel 1 are
Two air chambers 32 are formed inside by a partition wall 31 which is formed in a hollow shape having a thickness larger than the step size between the end edges of No. 1 and which is integrally molded. That is, the seal body 30 has a structure that is easily deformed and has high elasticity.

When the end surfaces 5a to 5c of the partition body 5 are attached to the inner box 3 of the heat insulating box body 1, the seal body 30 is interposed at the stepped portions of the end surfaces 5a to 5c, as shown in FIG. ,
The mounting seat 14 is fixed to the inner box 3 with the screw 15 while sandwiching the seal body 30. Since the seal body 30 has a structure which is easily deformed and has a high elasticity as described above, it is smoothly crushed and sandwiched. Therefore, the work of attaching the partition body 5 can be performed quickly. Further, since the seal body 30 is easily deformed, the seal body 30 is attached to the inner box 3 in a state of being in close contact over the entire length, and air leakage can be more reliably prevented.

Further, the seal body 19 made of moltoprene or styrene disclosed in the first embodiment described above gradually absorbs moisture when used for a long period of time, and particularly in the vicinity of the contact with the inner box 3, the frozen body 19 is frozen. Condensation may occur due to cooling by the cool air on the chamber 6 side. In that respect, since the seal body 30 of the present embodiment is made of soft rubber, it does not absorb such moisture, and therefore condensation is prevented from occurring.

<Third Embodiment> Next, a third embodiment of the present invention will be described with reference to FIGS. As illustrated in the above-described embodiment, in the refrigerator-freezer in which the partition 5 is attached to the inside of the heat-insulating box 1 to partition the freezer compartment 6 and the refrigerator compartment 7, the inside of the refrigerator compartment 7 In the boundary portion of the box 3 with the partition body 5 (for example, the portion indicated by reference numeral 35 in FIG. 8), the cold air in the freezer compartment 6 is cooled by being transmitted through the inner box 3, and the dew condensation is formed there. May occur. The third embodiment takes measures to prevent such dew condensation.

Therefore, as shown in FIG. 7, a plurality of elongated holes 36 are formed in two rows in the mounting portion of the partition 5 in the inner box 3 of the heat insulating box 1. These long holes 3
Reference numeral 6 functions to block transmission of cold air from the freezer compartment 6 to a portion 35 (a portion where dew condensation is likely to occur) which is a boundary between the inner box 3 on the refrigerating compartment 7 side and the partition body 5. That is, the heat insulating effect is obtained, and the cooling of the above-mentioned dew condensation-prone portion 35 is suppressed as much as possible.

Although the formation of the dew condensation is attempted by providing the elongated hole 36 as described above, there are still cases where the dew condensation cannot be sufficiently prevented. Therefore, as shown in FIG. 8, in the mounting portion of the partition body 5 in the inner box 3, a certain size is projected from the place where one row of the long holes 36 (row on the refrigerating compartment 7 side) is provided to the refrigerating compartment 7 side. A strip-shaped hygroscopic material 38 is attached to the open portion (the portion 35 where dew condensation is likely to occur). The hygroscopic material 38 is made of a shape memory polymer made of polyurethane resin, and functions so as to have high moisture absorption when the ambient temperature is higher than the glass transition temperature of the resin, and conversely lower moisture absorption when the ambient temperature is low. It is a thing. Then, the seal body 30 illustrated in the second embodiment is pressed against a part of the moisture absorbent body 38, and the partition body 5 is formed.
Is attached to the inner box 3.

For example, when a new object to be refrigerated is put in the refrigerating compartment 7, the refrigerating compartment 7 is in a relatively high temperature and high humidity state, and in particular, the portion 35 of the inner box 3 where dew condensation is likely to occur. Condensation may occur at. However, in the present embodiment, the hygroscopic material 3 is formed on the portion 35 where dew condensation easily occurs.
8 is provided, and the hygroscopic material 38 exhibits a high hygroscopicity when the ambient temperature is high, so that even if dew condensation is attempted, the moisture is effectively absorbed by the hygroscopic material 38, and the dew condensation is surely prevented. Note that the place where the hygroscopic material 38 is attached may be set so as to project from the position deviated from the long hole 36 to the refrigerating compartment 7 side, as shown in FIG. 9.

<Other Embodiments> The present invention is not limited to the embodiments described above and illustrated in the drawings. For example, the following embodiments are also included in the technical scope of the present invention. In addition, various changes can be made without departing from the scope of the invention. (1) In the third embodiment, as the hygroscopic material, a material that changes the hygroscopicity according to the ambient temperature is exemplified, but a normal hygroscopic material that exhibits a water absorbing function regardless of the ambient temperature may be used. .
