Description

  The present invention relates to a structure of a partition frame attached to a front opening of a heat insulating box constituting a storage body of a cooling storage.

  For example, a four-door type refrigerator has four entrances formed by attaching a cross-shaped partition frame to the front opening of a refrigerator body made of a heat insulating box, and each door is provided with a heat insulating door that can be opened and closed. The magnet packing attached to the peripheral edge of the back surface of each heat insulating door is attracted to the corresponding edge of the entrance and exit for sealing. Here, as a typical partition frame, a synthetic resin interior board having a gate-shaped cross section with an open front surface is fitted to the rear surface side of a magnetic metal plate having a gate-shaped cross section with an open rear surface. It has a structure in which a heat insulating material is foam-filled inside. The magnetic metal plate with a gate-shaped cross section was used for the exterior plate, by securing the magnet packing adsorption surface on the front part of the partition frame, and by increasing the rigidity of the front part to ensure flatness, This is to increase the adhesion of the magnet packing. Moreover, in order to prevent dew condensation on the front surface portion of the partition frame, a heater is attached to the back surface of the front surface portion.

By the way, in the partition frame of the said structure, since the exterior plate made of a metal plate extends from the front surface facing the outside air to the side surface facing the interior, the cold air inside the warehouse and the outside air are easily exchanged, and cooling I hate being inefficient. Moreover, since the front part of the partition frame is easily cooled by the cool air inside the cabinet, it is necessary to increase the amount of heat generated by the heater for preventing condensation.
Therefore, in order to save energy, the exterior plate of the partition frame has a structure in which the inner side of the compartment is made of synthetic resin and the outer side of the compartment is made of a metal plate, and the cool air inside the compartment is on the front side of the partition frame. Some are known to be difficult to transmit to (for example, Patent Document 1).

In the divided part of the outer box 11 and the decorative frame 32, the insertion part 30B of the outer box 11 is inserted and connected to a dead-end insertion groove 36 provided in the decorative frame 32. The occurrence of foam leakage from the divided portion is prevented.

Next, the structure of the partition frame 15 will be described using the vertical frame 15A as an example.
As shown in FIG. 4, the vertical frame 15 </ b> A includes a synthetic resin frame main body 50 having a gate-shaped cross section opened on the rear surface, and an interior plate made of a metal plate such as a stainless steel plate that closes the rear surface opening of the frame main body 50. 41 and an exterior plate 45 made of a metal plate such as a stainless steel plate, which is mounted on the surface of the front surface portion 51 of the frame main body 50. By assembling these, as shown in FIG. A rectangular tubular outer shell 40 having a rectangular cross section is formed.

  The interior plate 41 is formed in a gate-shaped cross section in which side plates 43 are bent at a right angle forward from both side edges of the rear plate 42 having a width comparable to the full width of the rear opening of the frame body 50. On the other hand, a thick wall portion 53 is formed at a position near the rear end of the back surface of the side wall portion 52 of the frame body 50, and the side wall plate 43 of the interior plate 41 is tightly attached to the base portion of the thick wall portion 53. An insertion groove 54 that is open to the rear and has a dead end shape is formed.

At the center in the width direction of the front surface portion 51 of the frame body 50, the mounting portion 55 of the exterior plate 45 described above is set over a region having a width dimension that is a little more than half of the full width, and both sides thereof are insulated. The magnet packing 18 attached to the door 17 serves as an attracting portion 56 that abuts. A magnetic metal thin plate 60 (hereinafter referred to as a magnetic thin plate 60) is attached to the surfaces of both adsorption portions 56.
The mounting portion 55 is formed so that the surface thereof is recessed by a predetermined dimension from the surfaces of the suction portions 56 on both sides, and is formed thinner than the suction portions 56 and the side portions 52. A groove forming portion 58 having a predetermined width is formed on the back surface of the boundary portion between the mounting portion 55 and the suction portion 56 so as to protrude rearward. The both groove forming portions 58 are formed with insertion grooves 59 that are open to the front surface and have a dead end shape from the positions of both side edges of the mounting portion 55.

The exterior plate 45 is formed in a gate-shaped cross section in which side plates 47 are bent rearward at right angles from both side edges of the front plate 46 having a width comparable to the entire width of the mounting portion 55 of the frame body 50. The side plate 47 of the exterior plate 45 can be tightly inserted into the insertion grooves 59 on both side edges of the mounting portion 55 described above, and the front plate 46 can be brought into contact with the surface of the mounting portion 55 that has been retracted by a predetermined dimension. At that time, the surface of the front plate 46 is set to be flush with the surface of the magnetic thin plate 60 attached to the adsorption portions 56 on both sides.
In addition, on the back surface of the mounting portion 55 of the frame main body 50, a dew condensation prevention heater 62 including a cord heater 62 is disposed along the length direction of the frame main body 50 at positions close to both side edges. It is like that.

An example of the manufacturing procedure of the vertical frame 15A is as follows. A magnetic thin plate 60 is attached to the surface of the adsorption portion 56 in the front surface portion 51 of the frame body 50. Next, both side plates 47 of the exterior plate 45 are tightly inserted into the insertion grooves 59 on both side edges of the mounting portion 55, and the back surface of the front plate 46 is attached to the surface of the mounting portion 55 via an adhesive such as double-sided tape. Affixed to. At this time, the surface of the front plate 46 of the exterior plate 45 and the surface of the magnetic thin plate 60 attached to the adsorption portions 56 on both sides are flush with each other.
Subsequently, the heater 62 is inserted from the rear surface opening of the frame body 50, and is vertically disposed at positions near both side edges of the back surface of the mounting portion 55, and is attached with aluminum foil tape or the like.

Next, both side plates 43 of the interior plate 41 are tightly inserted into insertion grooves 54 formed at positions near the rear end of the back surfaces of the side surface portions 52 of the frame main body 50, and the rear plate 42 causes the rear surface of the frame main body 50 to be The opening is blocked. Thereby, as shown in FIG. 5, the outer shell 40 incorporating the heater 62 is assembled.
Finally, the outer shell body 40 is set in a foaming jig, and the outer shell body 40 is filled with a heat insulating material 64 made of a foamed resin such as urethane foam. As shown in FIG. Manufacturing is complete.
The horizontal frame 15B is manufactured in the same manner.

The partition frame 15 of the present embodiment has the above-described structure, and as described above, the four entrances 16 are formed by being attached to the front opening 14 of the refrigerator main body 10 in a cross-shaped state. In addition, one vertical side edge of each doorway 16 and one horizontal side edge connected thereto are covered by the vertical frame 15A and the horizontal frame 15B.
Then, when the heat insulating doors 17 attached to the respective entrances 16 are closed, as shown in FIG. 6, the magnet packing 18 fitted on the back surface of the heat insulating door 17 is attached to the adsorption portion 56 of the partition frame 15. By being attracted and adhered to the magnetic thin plate 60, the interior is sealed from the outside.

  The partition frame 15 has a frame body 50 made of a synthetic resin that extends from the side surface portion 52 facing the interior to the front surface portion 51 facing the exterior, and is formed at the center in the width direction on the surface of the front surface portion 51. A metal exterior plate 45 having a gate-shaped cross section is inserted into a dead-end insertion groove 59 and attached to the set mounting portion 55. That is, since the synthetic resin material is interposed between the front plate 46 of the exterior plate 45 facing the outside and the interior of the exterior plate 45, it is difficult for cold heat in the interior to be transmitted to the exterior plate 45. Cooling efficiency is increased. Further, since the cooling of the front plate 46 of the exterior plate 45 is suppressed, the amount of heat generated by the heater 62 disposed on the back surface of the mounting portion 55 can be suppressed in order to prevent condensation on the surface of the front plate 46. . Therefore, it can contribute to energy saving.

Here, although the frame main body 50 is made of synthetic resin, a metal exterior plate 45 having a gate-shaped cross section is inserted into and attached to the center of the front surface portion 51 in the width direction. Functions as a reinforcing material to increase the rigidity of the front surface portion 51 and prevent deformation and the like. In other words, since the flatness of the front surface portion 51 including the attracting portions 56 at both ends in the width direction is ensured, the magnet packing 18 can be more closely adhered and sealed.
In addition, since the exterior plate 45 is attached to the attachment portion 55 of the frame main body 50 by being inserted into a dead-end insertion groove 59, there are divided portions from the front surface of the partition frame 15 to both side surfaces. Therefore, the occurrence of foam leakage during the foam filling of the heat insulating material 64 is prevented.
Further, since the thickness of the mounting portion 55 to which the heater 62 is mounted is smaller than the thickness of the other portions of the frame body 50, the heat of the heater 62 is transferred to the front plate 46 of the exterior plate 45. The amount of heat generated by the heater 62 can be suppressed.
