In other words, when the flap 53 is closed, it is preferable that the upper end of the protrusion 22X reaches the vicinity of the upper end of the area where cool air from the fan 43 reaches. In other words, when the refrigerator 1 is viewed from the front, the VF in the area where the cool air from the fan 43 directly reaches in the state where the flap 53 is closed by the convex portion 22X rising upward from the VF shelf 22 Preferably, the portion above shelf 22 is covered.

In a normal refrigerator, even if the R damper 52 is closed, cold air cooled by the evaporator 42 flows to the bottom surface of the R damper 52 or the flap 53. Condensation tends to occur in front of the However, with refrigerator 1 according to the present embodiment, the above configuration can reduce the possibility of condensation occurring in vegetable compartment 12 due to cooling of the lower portion of V-duct 51 .

Refrigerator 1 according to the present embodiment is configured as follows in order to fix partition frame 23 to freezer compartment 20 after urethane foaming.

Referring to FIG. 10 , door opening/closing sensor 27 for detecting opening/closing of door 13 a of first freezing area 13 is attached to partition frame 23 in the present embodiment. From the liner 94 of the freezer compartment 20, the electric wire 28 and the connector 29 for connecting to the door open/close sensor 27 are pulled out. More specifically, the wires 28 and the connectors 29 are pulled out from the liner 94 of the freezer compartment 20 of the heat insulation box 90 behind the part where the partition frame 23 is attached. In the present embodiment, the electric wire 28 and the connector 29 are pulled out from a hole opened in the liner 94 and then pulled out from a pull-out opening 97B formed in the front portion of the rail 97. As shown in FIG.

Behind the drawer opening 97B formed in the liner 94 or the rail 97, a storage portion 95X is formed for storing the electric wire 28 and the connector 29 during urethane foaming. In the present embodiment, the lower surface and the rear surface of the storage portion 95X are configured by the ribs 95 formed in the liner 94 of the second freezing area 15, and the upper surface of the storage portion 95X is configured by the lower surface of the rails 97, The front surface of the storage portion 95X is formed by the rear surface of an extension portion 97A, in which the front portion of the rail 97 extends downward. In this way, recesses are formed in the side surfaces of the freezer compartment 20, and the electric wires 28 and the connectors 29 are accommodated in the recesses during urethane foaming.

Next, as shown in FIG. 12, reinforcing members 24L and 24R are attached to recesses 91L and 91R for fixing partition frame 23 (step S104). By attaching the reinforcing members 24L, 24R, the shape of the concave portions 23L, 23R is kept from collapsing during urethane foaming.

A jig 200 as shown in FIG. 13 is prepared (step S106). The jig 200 has an upper portion 202 that slides vertically with respect to a lower portion 201 . A convex shape 202B is formed in the rear portion of the upper portion 202 . The convex shape 202B has the same shape as the concave portion at the rear portion of the lower surface 22B of the VF shelf 22 .

As shown in FIGS. 14 and 15, the jig 200 is inserted from the front of the refrigerator 1 into the freezer compartment 20, that is, the area below the VF shelf 22 (step S108).

When the jig 200 is fully inserted, the upper portion 202 of the jig 200 is lifted as shown in FIG. As a result, the convex shape 202B at the rear of the jig 200 comes into contact with the ceiling at the rear of the freezer compartment 20, that is, the inclined surface 22C at the rear of the lower surface 22B of the VF shelf 22 and the concave portion shown in FIGS. step S110).

In this state, urethane is injected into the heat insulating box 90 and foamed (step S112).

After urethane foaming, the jig 200 is removed from the heat insulation box (step S114).

As shown in FIG. 17, the evaporator 42 is attached to the rear end of the freezer compartment 20 (step S116).

As shown in FIG. 17, the fan 43 is attached to the upper rear surface of the lower EVA cover 45A (step S118).

As shown in FIG. 17, lower evaporator cover 45A is attached to the rear end of freezer compartment 20 (step S120).

As shown in FIGS. 17 to 21, the upper evacuator cover 45B is attached to the upper front surface of the lower evacuator cover 45A (step S122). 20 and 21, lower EVA cover 45A and upper EVA cover 45B are also collectively referred to as EVA cover 45. Referring to FIGS.

More specifically, in this embodiment, after lower evaporator cover 45A is attached to the back surface of freezer compartment 20, upper evaporator cover 45B is attached. The upper evacuator cover 45B according to the present embodiment is attached behind the sloped surface 22C at the rear of the VF shelf 22, and the upper end of the upper evacuator cover 45B is positioned higher than the ceiling of the freezer compartment 20, that is, the VF shelf 22 Since it reaches a position higher than the front part of the lower surface 22B, the lower evacuator cover 45A is attached, and then the upper evacuator cover 45B is attached to the concave portion of the rear part of the lower surface 22B of the VF shelf 22.例文帳に追加

Then, the V-duct 51 shown in FIGS. 22 and 23 is attached to the rear end portion of the upper surface of the VF shelf 22 (step S124). The V-duct 51 has a shape in which the lower half protrudes further forward than the upper half when attached to the rear surface of the vegetable compartment 12 . In other words, the V-duct 51 has a shape that bulges forward toward the bottom, that is, has a shape that dents rearward toward the top. This allows the cold air from the fan 43 to flow smoothly through the duct passage 51Y toward the refrigerator compartment 11. - 特許庁

In particular, in the present embodiment, projections 51L and 51R are formed on the lower portion of the back surface of V-duct 51. As shown in FIG. As shown in FIG. 24, the operator hooks the lower end 51X of the front surface of the V-duct 51 to the rear surface of the convex portion 22X of the VF shelf 22, and the protrusions 51L and 51R are attached to the rear surface of the vegetable compartment 12, that is, the insulation box. By pushing the upper portion of the V-duct 51 rearward while it is in contact with the liner 94 of the body 90, the protrusions 51L and 51R are slid downward. At this time, the protrusions 51L and 51R serve as fulcrums, and a force (forward) on the opposite side to the direction of the force applied to the upper portion of the V-duct 51 (backward) is generated at the lower end portion 51X. Therefore, the lower end portion 51X is reliably pushed into the rear surface of the convex portion 22X of the VF shelf 22. As shown in FIG. When the V-duct 51 is fixed to the rear surface of the vegetable compartment 12 in this manner, the V-duct 51 is press-fitted to the rear surface of the convex portion 22X of the VF shelf 22, thereby preventing cold air leakage and heat insulation deterioration.

The tape of the storage portion 95X is removed, and the electric wire 28 and the connector 29 are taken out from the storage portion 95X (step S126).

The connector 29 is connected to the door open/close sensor 27 of the partition frame 23 (step S128). More specifically, in the present embodiment, referring to FIG. 25, partition frame 23 has an end portion formed with hole 23X for inserting a connector. The operator connects the connector 29 to the door open/close sensor 27 after passing the connector 29 through the hole 23X. Therefore, the extra electric wires 28 and connectors 29 can be stored in the partition frame 23, and the electric wires 28 and connectors 29 can be prevented from being visually recognized or touched by the user.

The door open/close sensor 27 is fixed to the lower portion of the partition frame 23 (step S130).

As shown in FIGS. 25 and 26, both ends of the partition frame 23 are fitted into the reinforcing members 24L, 24R of the recesses 91L, 91R (step S132).

Both ends of the partition frame 23 are screwed into the screw holes 97C on the front surface of the rail 97 (step S134).

As described above, with regard to the refrigerator 1 according to the present embodiment, the cold air cooled by the evaporator 42 can smoothly flow into the freezer compartment while the cooling mechanism 40 having a relatively large size is provided and the size of the vegetable compartment is secured. 20, prevents the front of the V-duct 51 from being too cold, makes it easier to install the V-duct 51, and makes it possible to install the door open/close sensor 27 on the partition frame 23.例文帳に追加
