The structure is designed to prevent this.

  Next, a part of manufacturing process of the refrigerator according to the present invention will be described.

  As described above, the front partition 217a, the third partition 218, and the fourth partition 222 of the second partition 217 are assembled in advance on the inner box 203 side of the heat insulating box 201. It should be noted that components necessary for temporary mounting of the front partition 217a, the third partition 218, and the fourth partition 222 of the second partition 217 are attached to the inner box 203 or the like.

  A second air passage 216 is attached to the back of the third partition 218 and the fourth partition 222. As shown in FIG. 2, the attachment is performed by forcibly inserting a wedge-shaped attachment rib 251 protruding in the rear direction from the rear end portion of the third partition 218 into the second air passage 216. Specifically, the unitized third partition 218 and second air passage 216 are temporarily attached to the inner box 203. Next, the fourth partition 222 is temporarily attached in the inner box 203. At this time, the flange 225 of the fourth partition 222 and the flange 226 of the third partition 218 are engaged in the vertical direction as shown in FIG.

  Then, insert the inner box 203 attached with the front partition 217a, the third partition 218, and the fourth partition 222 of the second partition 217 from the open surface of the outer box 202 bent in a U-shape, A steel plate panel is attached to the open surface and the back surface to form a box before filling with the foam insulation.

  Then, it is set in a foaming jig, and the hard foamed urethane is filled in the space of the inner box 203 and the outer box 202. At that time, the rear part of the front partition 217a that cannot hold the inner box from the front with the inner box side tool is fixed by a movable jig.

  In addition, the opening part is provided also in the side peripheral edge of the 3rd partition 218 and the 4th partition 222, and the corresponding inner box 203, and the front partition 217a of the 2nd partition 217 is filled with hard foaming urethane. The third partition 218 and the fourth partition 222 are simultaneously filled with rigid foamed urethane and are integrally molded.

  Next, assembly of the first partition 211 and the second partition 217 will be described.

  The cooling chamber 210 is located across the freezer compartment 208 and the vegetable compartment 207 of the heat insulating box 201 integrally foamed with each partition, and the first for insulating and partitioning the front surface of the cooler 210a in the cooling chamber 210. The partition 211 is assembled from the front surface of the heat insulating box 201. At this time, since the rear of the front partition 217a of the second partition 217 has a space opened up and down, the first partition 211 can be easily assembled in the manufacturing process. Then, after the first partition 211 is assembled, a rear partition 217b for partitioning the rear space of the front partition 217a is assembled. The rear partition 217b includes a heat insulating material such as polystyrene foam inside, and is fixed to the front partition 217a with screws or the like so as to partition the rear space of the front partition 217a up and down from the upper vegetable compartment 207 side.

  With the above configuration, in the present embodiment, the second partition 217 that partitions the lowermost freezer compartment 208 of the heat insulation box 201 and the vegetable compartment 207 thereabove is composed of a front partition 217a and a rear partition 217b. In order to insulate and partition the front surface of the cooler 210a in the cooling chamber 210 located over the freezer compartment 208 and the vegetable compartment 207 by integrally molding only the front partition 217a with the heat insulation box 201 and the foam insulation material. The structural strength of the heat insulating box 201 by integral foaming can be increased while allowing the first partition 211 to be assembled. This is because the first partition 211 must have a structure that can be attached and detached by replacing cooling components (cooler, blower, etc.) in the cooling chamber 210 after assembly. It is possible to increase the structural strength. The reason why the cooling chamber 210 straddles the upper and lower chambers (the freezer compartment 208 and the vegetable compartment 207) is to enable efficient cooling of the freezer compartment 208 and the vegetable compartment 207 and to increase the depth dimension from the usability side. This is due to the necessity of arranging the blower above the cooler by reducing the depth of the cooler.

  In the present embodiment, in addition to the front partition 217a of the second partition 217, the inside of the third partition 218 and the fourth partition 222 constituting the plurality of partitions is simultaneously filled with rigid foamed urethane. Since it is integrally molded, further structural strength can be increased by integrally firing all the partitions in the vertical direction. In particular, from the standpoint of improving usability and storage performance in recent years, it is a very effective technology for reducing the wall thickness of the insulated box body for the purpose of improving the volumetric efficiency of a refrigerator having a plurality of storage rooms above and below. Become.

  In addition, since the depth of the front partition 217a formed integrally with the heat insulating box 201 and the foam heat insulating material is smaller than the depth of the rear partition 217b, the assembly workability of the first partition 211 incorporated after foaming is surely improved. Can do.

  In addition, the portion of the inner box 203 where the both side surfaces of the front partition 217a are connected to each other is provided with receiving portions 233 for supporting the both side surfaces of the front partition 217a downward, so that the front partition 217a can be easily positioned. The rigidity around the front partition 217a after the integral foaming can be further increased.

  Further, since the flanges 232 are provided on the outer periphery of both side surfaces of the front partition 217a, the rigidity around the front partition 217a due to the close contact between the integrally foamed flange 232 and the inner box 203 is increased. Further, the flange 232 also has a role of preventing rigid foam urethane leakage during integral foaming.

  The front partition 217a has a door switch 234 such as a Hall IC that detects opening / closing of a door (not shown) on the front surface of the front partition 217a, and the harness 235 (conductor) passes through the opening 236 on the inner box 203 side. With the structure communicating with the opening 236, the hole for penetrating the inner box 203 of the harness 235 can also be used as the opening 236, and the cost can be reduced by reducing the number of seals.

  In addition, since the vacuum heat insulating material 230 is disposed on the side surface of the outer box 202 in the heat insulating box body 201 so as to wrap at least on the projection surfaces on both sides of the front partition 217a, the front partition after integral foaming is improved. Deformation of the outer box due to shrinkage of the foamed heat insulating material around 217a can be prevented.

  In addition, since the switching chamber 205 and the ice making chamber 206 sandwiched between the third partition 218 and the fourth partition 222 that are foamed with hard urethane foam are the lowest in the storage chamber, a heat insulating box After urethane foaming 201, when the second air passage 216 is attached to the back of the switching chamber 205 and the ice making chamber 206, the workability becomes very bad. In this embodiment, the second air passage 216 is Workability can be improved by attaching before urethane foaming.

  Further, in the present embodiment, the compressor 209 is housed in a recess formed stepwise on the back surface of the uppermost refrigeration chamber 204, so compared to the case where it is installed on the back surface of the lowermost portion, which is generally conventional, It is possible to achieve both the effective use of the rear part of the uppermost refrigerator compartment 204, which is difficult to use, and the improvement of usability by increasing the depth of the lowermost storage room equipped with a drawer door. And the problem which arises when it is set as this form, ie, the noise and the vibration from the compressor 209 which approached the user, are also suppressed by the improvement of the structural strength by integral foaming of the front partition 217a. In addition, due to an increase in weight due to an increase in the storage capacity of the lowermost storage chamber (freezer compartment 208), the deformation of the heat insulating box 201 when the freezer compartment door is pulled out is also improved in structural strength by integral foaming of the nearest front partition 217a. It is suppressed by.
