Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a so-called drawer type door used for a storage.

[0002]

FIGS. 15 and 16 show a conventional structure of a drawer type door in a refrigerator. Door body 1
Is composed of a door outer plate 2 made of a steel plate, caps 3a and 3b mounted on the upper and lower sides of the door outer plate 2, and a gasket mounting sash 4 mounted on a peripheral portion on the back side (left side in FIG. 16). The gasket mounting sash 4 is formed in a box shape and has a space 5 formed therein.
Is formed.

[0003] A reinforcing member 6 made of an iron plate and having substantially the same size as the opening 4a is fixed to the back side of the door body 1 by, for example, screws. The reinforcing member 6 has a circular urethane inlet 6a formed at the center and screw mounting holes 6b formed at both left and right sides. A back paper 7 is attached to the back surface (the left surface in FIG. 16) of the reinforcing member 6.

A cut 8 is formed near the corner of the back paper 7, and the back paper 7 uses the cut 8 so as to sandwich the opening edge of the gasket mounting sash 4 so as to sandwich the gasket. It is attached to the attachment sash 4. The back paper 7 also has a circular urethane inlet 7a corresponding to the urethane inlet 6a at the center and a screw insertion hole 7b corresponding to the screw mounting hole 6b at both left and right sides. I have. A portion between the screw mounting hole 6b of the reinforcing member 6 and the screw insertion hole 7b of the backing paper 7 is adhered by a double-sided adhesive tape 9 (shown by a dotted line in FIG. 15). Thus, the door shell 10 is configured.

[0005] Thus, the door shell 1 constructed as described above.
Reference numeral 0 denotes a state in which the backing paper 7 is placed in an upside-down state in a foaming jig (not shown). The space 5 is filled with a foamed heat insulating material 11 made of urethane foam. After this,
As shown in FIG. 16, a plastic door inner plate 12 is attached so as to overlap the backing paper 7, and a support for supporting a storage container (not shown) is provided on the reinforcing member 6 via the door inner plate 12. The member 13 is attached by a screw 14.

However, the above-described conventional configuration has the following disadvantages. That is, since the reinforcing member 6 made of an iron plate has substantially the same size as the opening 4 a of the gasket mounting sash 4, heat in the storage compartment of the refrigerator is easily transmitted to the outer peripheral side of the door via the reinforcing member 6. . For this reason, dew is easily generated on the surface of the door, and in some cases, a structure for preventing dew is required. Further, since the reinforcing member 6 is large, the weight of the entire door is also heavy.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a door of a storage which can make it difficult for heat in the storage chamber to be transmitted to the outer peripheral side of the door and reduce the weight of the entire door. To provide.

[0008]

In order to achieve the above object, a first aspect of the present invention is a box-shaped door body having an opening on the back surface and a space inside the door body. Door inner plate arranged to close the opening on the back of the door,
The outer shape is formed smaller than the opening on the back surface of the door main body, and is attached in a state where a part of the inner surface of the door inner plate is in contact with the space portion side, and forward from the contact surface with the door inner plate. A first bent piece bent toward the rear, and a first bent piece bent rearward from a tip end of the first bent piece.
A reinforcing member integrally having a second bent piece portion forming an acute angle smaller than 90 degrees between the bent piece portion and the space portion of the door main body; A foam insulating material in which the first and second bent pieces of the reinforcing member are buried, and a support member attached to and fixed to the reinforcing member via the door inner plate and supporting a storage container. It is characterized by having.

According to such means, since the reinforcing member is formed smaller than the opening on the back surface of the door main body, heat in the storage becomes difficult to be transmitted to the outer peripheral side of the door, and the weight of the entire door is reduced. Is also lighter.

In addition, since the reinforcing member is formed small and the reinforcing member is formed with the first and second bent pieces which form the acute angle portion, when the door is opened, foam insulation is provided. Peeling between the material and the reinforcing member can be prevented as much as possible.

In this case, it is preferable that the first and second bent pieces of the reinforcing member are provided on a side close to a handle provided on the front surface of the door body.

According to a third aspect of the present invention, in order to achieve the same object as in the first aspect, a box-shaped door body having an opening on the back surface and a space inside thereof, and a back surface of the door body A door inner plate arranged to close the opening, and the outer shape is formed smaller than the back opening of the door body,
A reinforcing member attached in a state that a part thereof is in contact with the surface of the door inner plate on the space portion side; a foam heat insulating material foam-filled in the space portion of the door main body by an in-situ foaming method; On the surface on the space side of the plate, of the peripheral portion of the portion where the door inner plate and the reinforcing member are in contact with each other, at least a portion on the upstream side at the time of foam filling of the foam heat insulating material is provided integrally. And a support member fixed to the reinforcing member via the door inner plate and supporting the storage container.

[0013] According to such means, as in the case of the first aspect, since the reinforcing member is formed smaller than the opening on the back surface of the door body, heat in the storage is transferred to the outer peripheral side of the door. It becomes difficult to be transmitted, and the weight of the entire door is reduced.

[0014] Further, on the surface of the door inner plate on the space portion side, of the peripheral portion of the contact portion between the door inner plate and the reinforcing member,
Since the ribs are provided integrally at least on the upstream side at the time of foam filling of the foam heat insulating material, it is possible to prevent the foam heat insulating material from entering the contact portion between the door inner plate and the reinforcing member as much as possible.

In this case, there are two ribs, two parallel to the side where the handle portion of the door body is located, and two ribs extending in a direction perpendicular to the side where the handle portion is located. It is preferable that the two ribs orthogonal to the side where the rib exists are set to be longer than the interval between the two ribs parallel to the side where the handle portion exists.

It is preferable that the ribs provided on the upstream side at the time of foam filling of the foam heat insulating material are set higher than the ribs provided on the downstream side.
The rib may be provided with an engagement claw that engages with and holds the reinforcing member.

Furthermore, the rib is provided so as to surround the portion where the door inner plate and the reinforcing member are in contact with each other, and of the portion surrounded by the rib, the furthest from the injection portion of the foamed heat insulating material. It is preferable to provide a gas vent hole or slit in the vicinity.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. First, FIG.
A refrigerator 21 as a storage is shown. In the refrigerator 21, the top end of the refrigerator compartment door 22 is pivotally supported at one end via a hinge (not shown), and is a so-called pivot type. On the other hand, the door 23 for the upper freezer compartment, the door 24 for the lower freezer compartment, and the door 25 for the lowermost vegetable compartment are all of a so-called drawer type that slide in the front-rear direction. Doors 23, 24, 25 for the upper freezer compartment, the lower freezer compartment, and the vegetable compartment
Is basically the same, and the following description will be made on behalf of the upper freezing compartment door 23 (corresponding to the door of the present invention).

First, as shown in FIGS. 1 and 2, the door main body 26 of the door 23 has a door outer plate 27 made of a steel plate and a door outer plate 2 made of the same.
7 and a gasket mounting sash 30 mounted on the peripheral edge of the back side (left side in FIG. 2), and has a space 31 formed therein. And a gasket mounting sash 3
0 has a rectangular opening 32 formed therein. A handle 33 is provided on the upper side of the front side of the upper cap 28. A gasket mounting groove 34 for mounting a gasket (not shown) is formed in the peripheral portion of the gasket mounting sash 30.

A door inner plate 35 made of, for example, plastic is formed on the back side of the door body 26 so as to close the opening 32.
Is disposed, and a foam heat insulating material 37 made of urethane foam is foam-filled in the space 31 of the door outer shell 36 formed by the door main body 26 and the door inner plate 35 as described later. . The door inner plate 35 has a circular injection port 3 at the center.
8, and a ridge 39 projecting rearward (to the left in FIG. 1) is formed on the outer peripheral portion. And
Iron plate reinforcing members 40 are attached to the left and right two places on the space portion 31 side (front side) of the door inner plate 35 by, for example, a double-sided adhesive tape (not shown). Here, the outer shapes of both reinforcing members 40 are formed sufficiently smaller than the opening 32.

Since the left and right reinforcing members 40 have the same configuration, only one reinforcing member 40 will be described. In the reinforcing member 40, a central rectangular mounting portion 41 is bonded to the door inner plate 35. At the upper part of the mounting part 41, a first bent piece part 42 bent substantially 90 degrees forward is provided.
And a second bend that is bent rearward from the distal end of the first bent piece portion 42 to form an acute angle portion 43 smaller than 90 degrees with the first bent piece portion 42. One part 44,
A third bent piece 45 bent so as to be parallel to the door inner plate 35 is formed integrally with the tip of the second bent piece 44.

At the lower portion of the mounting portion 41, a fourth bent piece 46 bent substantially 90 degrees toward the front, and a door inner plate 35 at the tip of the fourth bent piece 46 are provided. And a fifth bent piece portion 47 bent so as to be parallel to. The mounting portion 41 has a mounting hole 49 for mounting a screw 48. A support member 5 for supporting a storage container (not shown) is provided on the rear side of the door inner plate 35.
0 is attached to the reinforcing member 40 by a screw 48. Although not shown, a gasket provided with a magnet is mounted in the gasket mounting groove 34.

In the above configuration, the handle 33 of the door 23
, The storage container supported by the door 23 and the supporting member 50 is pulled out, and when the storage container is pushed in, the door 23 and the storage container are pushed in.

Here, a procedure for manufacturing the door 23 will be described. First, the door outer plate 27 and the upper and lower caps 28, 2
9 and the gasket mounting sash 30 are assembled to form the door body 26. Then, the two reinforcing members 40, 40
Is disposed on the back surface of the door body 26 so as to cover the opening 32. The door outer shell 36 thus configured is housed in a foaming jig (not shown) with the door inner plate 35 facing upward, and in this state, the undiluted liquid urethane foam is poured into the space 31 from the inlet 38. The space 31 is filled with the foamed heat insulating material 37 by injecting, foaming and curing the stock solution. At this time, each bent piece portion 42, 44, 45, 46, 47 of the reinforcing member 40 and the acute angle portion 4
3 is buried in the foam heat insulating material 37. After this,
A support member 50 is attached to the rear surface side of the door inner plate 35 with screws 48. A gasket (not shown) is mounted in the gasket mounting groove 34.

According to the above-described embodiment, since the reinforcing member 40 made of an iron plate is formed sufficiently smaller than the rear opening 32 of the door main body 26, the heat in the storage (freezer compartment) is reduced by the door. 23 is hardly transmitted to the outer peripheral side. Therefore, door 2
The occurrence of dew on 3 can be prevented as much as possible. Further, since the reinforcing member 40 is reduced, the weight of the entire door 23 is reduced.

By the way, in the case of such a configuration, the contact area between the reinforcing member 40 and the foamed heat insulating material 37 is reduced by the size of the reinforcing member 40, and accordingly, the adhesive strength between them is also reduced. Will be smaller. Further, the mounting strength of the door 23 is maintained by the adhesive strength of the portion where the reinforcing member 40 is in contact with the foamed heat insulating material 37 and the strength of the reinforcing member 40 itself and the foamed heat insulating material 37 itself.

In the above configuration, the handle 33 of the door 23
4 and the reinforcing member 40 has
The forces F1, F2, F3 shown in FIG. Here, as shown in FIG. 5, it is assumed that the foamed heat insulating material 37 is peeled off from the acute angle portion 43 formed by the first and second bent pieces 42 and 44 in the reinforcing member 40 (the peeled portion). Is denoted by reference numeral 51), and this is not realized unless the first bent piece portion 42 is deformed downward (in the direction of arrow A). In order to deform the first bent piece portion 42 downward, the foamed heat insulating material 37 is required.
Needs to be compressed and deformed. However, since the force for compressively deforming the foamed heat insulating material 37 is substantially orthogonal to the force that the reinforcing member 40 receives from the screwing portion, this phenomenon is unlikely to occur.

Therefore, in this case, as shown in FIG.
Over a wide area near the acute angle portion 43 of the reinforcing member 40,
It is necessary to peel them almost at the same time (a peeled portion is denoted by reference numeral 52) or, as shown in FIG. 7, to generate a crack 53 in the foamed heat insulating material 37 itself, which requires a large force. On the other hand, as shown in FIG. 8, when the upper portion of the reinforcing member 40 is not the acute angle portion 43 but the right angle portion 54, the portion 54a extending outside the right angle portion 54 is deformed. As a result, peeling 55 occurs. At this time, the direction of the force for deforming the right-angled portion 54 of the reinforcing member 40 (the direction of arrow B) matches the direction of the force that the reinforcing member 40 receives from the screwing portion, and such peeling 55 is relatively easy. Will occur.

When the door 23 is opened, the force for peeling the foamed heat insulating material 37 is generated on the side of the handle 33 (upper side) of the reinforcing member 40. In the refrigerator 21, when the door 23 is opened, a force for removing the magnetic attraction force of the gasket is required. Generally, when the door 23 is opened, a larger force is required than when the door 23 is closed. Therefore, it is understood that the acute angle portion 43 of the reinforcing member 40 is more effectively provided on the side of the handle 33. Of course, such an acute angle portion 43 may be provided not only on the handle portion 33 side but also on another side side.

FIGS. 9 to 11 show a second embodiment of the present invention. The second embodiment differs from the first embodiment in the following points. That is, the four ribs 61, 61 and 62, 62 are integrally provided on the surface of the plastic door inner plate 35 on the space portion 31 side (front side) so as to surround the periphery of the mounting portion 41 of the reinforcing member 40. ing. In this case, the heights of the four ribs 61, 61 and 62, 62 are the same, and are set higher than the auxiliary bent pieces 63 formed on the left and right sides of the reinforcing member 40.

The four ribs 61, 61 and 62, 6
2, the length L1 of two ribs 61 perpendicular to the side (upper side) of the door main body 26 where the handle 33 is located is two ribs parallel to the side where the handle 33 is located. It is set so as to be longer than the distance L2 between 62, 62 (see FIG. 11). Therefore, the ribs 61 extending vertically extend above and below the mounting portion 41 of the reinforcing member 40. In this case, the reinforcing member 40
May be attached to the door inner plate 35 via a double-sided adhesive tape, or may be fitted to the four ribs 61, 61, 62, 62 using the fitting force. .

The second embodiment has the following advantages in addition to the first embodiment. That is, the reinforcing member 4
Since the periphery of the mounting portion 41 is surrounded by the four ribs 61, 61, 62, 62 provided on the door inner plate 35, the mounting portion 41 of the reinforcing member 40 and the mounting portion 41 of the reinforcing member 40 are filled when the foam heat insulating material 37 is filled with foam. Intrusion of the foamed heat insulating material 37 between the door inner plate 35 and the door inner plate 35 can be prevented as much as possible.

Further, by providing the ribs 61 and 62, the contact area between the door inner plate 35 and the foam heat insulating material 37 is increased, and when the door 23 is opened, the foam heat insulating material 37 and the door inner plate 37 are opened. It is possible to suppress the occurrence of peeling between the base material and the base material 35. Considering that peeling occurs between the foam heat insulating material 37 and the door inner plate 35, the peeling occurs first from a contact portion between the foam heat insulating material 37 and the reinforcing member 40. Spread along the direction. At this time, the rib 61 extending in the vertical direction extends longer than the mounting portion 41 of the reinforcing member 40, and a portion protruding from the reinforcing member 40 prevents the door inner plate 35 from being deformed,
As a result, the area in which the foam heat insulating material 37 must be peeled off at one time increases. For this reason, there is an advantage that the door inner plate 35 is hardly peeled off from the foam heat insulating material 37.

FIG. 12 shows a third embodiment of the present invention. The third embodiment differs from the second embodiment in the following points. FIG. 12 is a cross-sectional view of the right reinforcing member 40 in FIG. Reinforcing member 4
Of the ribs provided so as to surround the 0 mounting portion 41, the rib 64 on the left side in the drawing on the side near the injection port 38 at the center (the upstream side at the time of foam filling of the foam heat insulating material 37).
Is the right side in the figure on the side remote from the injection port 38 (foam insulation 37
(A portion on the downstream side during foam filling). The other ribs 66 (upper and lower)
It is formed at the same height as the rib 64 on the left side in the figure. In this case, the ribs 64 and 66 are set higher than the auxiliary bent piece 63 of the reinforcing member 40, and the rib 65 is set lower than the auxiliary bent piece 63.

When foaming the stock solution of foam insulation 37,
Each rib 64-66 acts to impede the flow of the stock solution,
In particular, since a large pressure is applied to the rib 64 on the upstream side near the inlet 38, the ribs 64 and 66 are increased, so that the foam insulating material is provided between the mounting portion 41 of the reinforcing member 40 and the door inner plate 35. 37 is prevented as much as possible.

FIG. 13 shows a fourth embodiment of the present invention. The fourth embodiment differs from the second embodiment in the following points. That is, two engaging claws 67 are integrally provided on each of the two ribs 61 extending vertically, and each of the engaging claws 67 is engaged with the auxiliary bending piece 63 of the reinforcing member 40. This allows the reinforcing member 4 to be mounted in a state where the mounting portion 41 of the reinforcing member 40 is in close contact with the door inner plate 35.
0 is attached to the door inner plate 35. In this case, a double-sided adhesive tape or an adhesive for attaching the reinforcing member 40 is not required.

In this embodiment, the length of the two ribs 61 extending in the up-down direction is longer than the length of the reinforcing member 40 in the up-down direction. Further, at the lower part of the reinforcing member 40, similarly to the upper part, first and second bent piece parts 42 and 44 forming the acute angle part 43 and a third bent piece part 45 are formed.

FIG. 14 shows a fifth embodiment of the present invention. The fifth embodiment differs from the second embodiment in the following points. That is, of the portion surrounded by the four ribs 61 and 62 provided around the mounting portion 41 of the reinforcing member 40, the portion farthest from the injection port 38 which is the injection portion of the foamed heat insulating material 37, in this case, Two ribs 61 extending in the direction
A rib 62 extending in the left-right direction of the outer rib 61
A slit 68 for venting gas is formed in the vicinity of the intersection.

Incidentally, when the periphery of the mounting portion 41 of the reinforcing member 40 is completely surrounded by the four ribs 61 and 62, gas escapes at the surrounded portion when the foamed heat insulating material 37 foams. Unfilled portions may remain without being cut, but by forming the slits 68 as described above, this can be prevented as much as possible. A similar effect can be obtained by forming a hole instead of the slit 68.

The present invention is not limited only to the above-described embodiments. For example, the reinforcing member 40 may be constituted by one piece instead of being divided into two pieces. It can be modified and implemented.

[0041]

According to the first aspect of the present invention, the reinforcing member is
Since it is formed smaller than the opening on the back surface of the door body, the heat in the storage becomes difficult to be transmitted to the outer peripheral side of the door, and the weight of the entire door can be reduced. In addition, since the reinforcing member is formed small and the first and second bent pieces forming the acute angle portion are formed on the reinforcing member, when the door is opened, the foamed heat insulating material and the reinforcing material are used. It is possible to prevent peeling between members from occurring as much as possible.

According to the second aspect of the present invention, the first and second bent pieces forming the acute angle portion are provided on the side close to the handle, so that the foamed heat insulating material and the reinforcing member are not separated. This can be more effectively prevented.

According to the third aspect of the invention, similarly to the first aspect, the reinforcing member is formed smaller than the opening on the back surface of the door body, so that the heat in the storage is transferred to the outer peripheral side of the door. And the weight of the entire door can be reduced. In addition, a rib is integrated with at least a portion of the peripheral portion of the door inner plate on the space portion side where the door inner plate and the reinforcing member are in contact with at least the upstream side during foam filling of the foam heat insulating material. With this arrangement, it is possible to prevent the foamed heat insulating material from entering the contact portion between the door inner plate and the reinforcing member as much as possible, and to prevent peeling between the foamed heat insulating material and the door inner plate. It can be suppressed as much as possible.

According to the fourth aspect of the present invention, the two ribs orthogonal to the side where the handle is present are set to be longer than the distance between the two ribs parallel to the side where the handle is present. Thereby, the occurrence of peeling between the foam heat insulating material and the door inner plate can be more effectively prevented. According to the invention of claim 5, it is possible to more effectively prevent the foamed heat insulating material from entering the contact portion between the door inner plate and the reinforcing member.

According to the sixth aspect of the present invention, since the engagement claws are provided on the ribs, a double-sided adhesive tape or an adhesive for attaching the reinforcing member to the door inner plate can be eliminated. According to the invention of claim 7, it is possible to prevent the unfilled portion of the foamed heat insulating material from remaining in the portion surrounded by the ribs.
