  Reference numeral 16 denotes a refrigerator compartment partition member provided at the back of the refrigerator compartment 2. A cold air duct 17 is provided on the back of the refrigerator compartment partitioned by the refrigerator compartment partitioning member 16. The cold air duct 17 is formed in a heat insulating material included in the refrigerator compartment partition member 16. Details will be described later. The cool air cooled by the cooler 12 is blown from the cooler chamber 10 to each storage chamber by the cool air circulation blower 14. Thereafter, the cool air blown to each storage room is returned to the cooler room 10, cooled by the cooler 12, and sent to each storage room again. That is, a cold air circulation structure is formed.

  A specific cold air circulation structure will be described. First, in the ice making room 3 a-1, the quick freezing room 3 a-2, and the freezing room 3 a, the ice making room 3 a is supplied from the freezing room cold air discharge port 21 provided at the upper part of the freezing room partition member 11 by the cool air circulation blower 14. -1 and the quick freezer 3a-2.

  Next, in the refrigerator compartment 2, a part of the cold air blown by the cold air circulation blower 14 is blown to the cold air duct 17 of the refrigerator compartment partition member 16 via the electric damper 20. The electric damper 20 is provided at the cold air upstream position of the cold air duct 17 of the refrigerator compartment partition member 16. Although specifically described in detail, the electric damper 20 is provided in a lower portion of the refrigerator compartment partitioning member 16 and in a damper storage portion 34 communicating with the cold air duct 17. Thereby, in order to keep the refrigerator compartment 2 at preset temperature, the amount of cold air sent to the refrigerator compartment 2 is adjusted. Then, cold air is blown into the refrigerating chamber 2 from the refrigerating chamber cold air discharge ports 21 a provided in the vertical direction so as to communicate with the cold air duct 17 in the refrigerating chamber partition member 16. Here, the refrigerating room cold air discharge ports 21a are provided at positions at which the cold air is blown out above the shelves 33 in which a plurality of the refrigerating room 2 are provided in the vertical direction in the refrigerating room 2 and on which stored items are placed.

  The chilled air after cooling the refrigeration chamber 2 is supplied from a refrigeration chamber cold air return duct 23 provided on the heat insulating partition wall 22 that partitions the refrigeration chamber 2 from the ice making chamber 3a-1 and the quick freezing chamber 3a-2. It is returned to the cooler chamber 10 through the cold air return path.

  Next, the vegetable room 4 is cooled by blowing the cold air in the cold room return air passage, which is the return passage of the cold room 2 described above, into the vegetable room 4. In addition, when the vegetable room 4 does not become preset temperature, in addition to the cold air which passed through the refrigerator compartment cold air return path, the structure which makes the vegetable room 4 blow out the cold air which passed through the electric damper 20 directly may be sufficient.

  The cold air blown into the vegetable compartment 4 is returned to the cooler 12 through the vegetable compartment cold air return duct 25 formed in the heat insulating partition wall 24 that partitions the freezer compartment 3 a and the vegetable compartment 4.

  With the cold air circulation structure as described above, each storage chamber is maintained at a predetermined temperature.

  Next, the refrigerator compartment partition member 16 is demonstrated using FIG.4, FIG.5, FIG.6. FIG. 4 is a front perspective view of a refrigerator compartment partition member provided on the back of the refrigerator compartment of the refrigerator of FIG. FIG. 5 is a front perspective view of a heat insulating material for forming a cold air duct used for the refrigerator compartment partition member of FIG. 4. 6 is a perspective view of an electric damper for adjusting the amount of cool air provided in the refrigerator compartment partition member of FIG.

  As shown in FIG. 3, the refrigerator compartment partition member 16 is attached to the rear of the refrigerator compartment 2a. A cooling promotion plate 31 made of metal (for example, aluminum) is provided on the front surface of the refrigerator compartment partition member 16. Thereby, the cooling promotion plate 31 itself is cooled, and the inside of the refrigerator compartment 2 can be uniformly cooled by the heat transfer from the cooling promotion plate 31.

  Moreover, the refrigerator compartment partition member 16 is comprised by the decorative board 16a and the heat insulating material 16b which form the front, as shown in FIG. And the cooling promotion board 31 is attached to the decorative board 16a side.

  Further, the decorative plate 16a is provided with cold storage air outlets 21a at positions corresponding to the plurality of shelf plates 33 provided in the vertical direction.

The decorative plate 16 a covers the entire back surface of the refrigerator compartment 2 and also serves as a back wall of the refrigerator compartment 2.

  Reference numeral 34 denotes an electric damper 20 storage portion formed so that the lower portion of the refrigerator compartment partitioning member 16 protrudes toward the refrigerator compartment 2 side. As shown in FIG. 3, the electric damper 20 is also provided in the damper housing portion 34 so as to be surrounded by the heat insulating material 16 b so as to be in communication with the cold air duct 17.

  The damper storage part 34 is provided close to the right side when viewed from the front of the refrigerator compartment partition member 16. Thereby, since the left side sees from the front of the damper accommodating part 34 rather than the right side, the refrigerator compartment 2 can be used more widely. Moreover, the lower end of the heat insulating material 16b is formed in the magnitude | size which protrudes below from the decorative board 16a. Thereby, as shown in FIG. 3, when the heat insulation partition wall 22 and the refrigerator compartment partition member 16 are assembled to face each other, the lower end of the heat insulation material 16b is formed so as to enter the heat insulation partition wall 22 side.

  Moreover, the heat insulating material 16b has the electric damper 20 in the lower part, and has the cold air duct 17 in the upper part. As shown in FIG. 5, the cold air duct 17 is connected above the damper housing portion 34 of the heat insulating material 16 b, the first heat insulating material portion 35 connected above the damper housing portion 34, and the first heat insulating material portion 35. Each is formed in the second heat insulating material portion 36. The damper housing part 34, the first heat insulating material part 35, and the second heat insulating material part 36 are formed separately and then assembled together. In addition, each seam is sealed so as not to cause cold air leakage.

  Furthermore, as shown in FIG. 5, the cooler outlets 34a, 35a, and 36a are provided in the damper storage part 34, the first heat insulating material part 35, and the second heat insulating material part 36, respectively. Further, the cold air outlets 34a, 35a, and 36a are provided at positions corresponding to the refrigerator compartment cold air outlets 21a provided on the decorative plate 16a, respectively.

  The electric damper 20 shown in FIG. 6 is provided in the damper storage part 34. The electric damper 20 is for one motor and two baffles. One baffle adjusts the amount of cold air sent to the refrigerator compartment 2. The other baffle adjusts the amount of cold air sent to the vegetable compartment 4. Therefore, each baffle of the electric damper 20 is installed corresponding to a cold air passage to the refrigerator compartment 2 and a cold air passage to the vegetable compartment 4 respectively.

  The electric damper 20 drives the motor based on a temperature detected by a temperature sensor (not shown) to operate the flapper (baffle) from open to closed or from closed to open. Thereby, the amount of cold air sent to the refrigerator compartment 2 and the vegetable compartment 4 is adjusted, and the refrigerator compartment 2 and the vegetable compartment 4 are set to preset temperature.

  Further, the opening 20a of the electric damper 20 communicates with the cold air duct 17 formed in the first heat insulating material portion 35 constituting the heat insulating material 16b. The opening 20b communicates with a duct through which cool air for cooling the vegetable compartment 4 (not shown) passes.

  5 and 6, reference numeral 37 denotes a lead wire. The lead wire 37 is a lead wire that supplies power to the electric damper 20. One end of the lead wire 37 is connected to the electric damper 20, and the other end is provided with a connecting portion 37b. The connection part 37b is connected to the refrigerator main body 1 side.

The receiving portion of the locking claw 18 is provided on the refrigerator main body 1 and / or the heat insulating partition wall 22. Therefore, since it is the structure which does not use a screw etc., it can be incorporated and fixed to the refrigerator main body 1 without a tool.

  Here, generally, when inspecting the refrigerator compartment partition member 16, it is not usually necessary to remove the lead wire 37. Moreover, since the electric damper 20 is provided in the heat insulating material 17b, the lead wire 37 cannot be attached or detached easily. Therefore, when inspecting the refrigerator compartment partition member 16, it is desirable that the inspection can be performed with the lead wires 37 connected.

  Therefore, in the present embodiment, the lead wire 37 has a length having a slack portion 37a in a state where both ends are connected. As an example, the slack portion 37a has such a length that the connection is not disconnected even when the refrigerator compartment partition member 16 is tilted forward as shown by the dotted line in FIG. In other words, the electric damper 20 provided on the refrigerator compartment partition member 16 side moves as the refrigerator compartment partition member 16 rotates, but the slack portion 37a follows this movement. Therefore, the refrigerator compartment partition member 16 can be inspected while the lead wire 37 is connected.

  Moreover, the damper accommodating part 34, the 1st heat insulating material part 35, and the 2nd heat insulating material part 36 are comprised by the different body. Thereby, in the connection state of the lead wire 37, for example, only the first heat insulating material part 35 can be removed and inspected, so that frost clogging in the cold air duct 17 can be easily eliminated.

  As described above, when inspecting the electric damper 20 and the cold air duct 17, even when the lead wire 37 is connected, the locking claws 18 of the refrigerator compartment partition member 16 are removed and moved to the position indicated by the broken line shown in FIG. can do. It is also possible to remove the refrigerator compartment partition member 16 by removing the lead wire 37.

  The lead wire 37 of the electric damper 20 has a length having a slack portion 37 a between the refrigerator compartment partition member 16 and the refrigerator main body 1. Thereby, the refrigerator compartment partition member 16 can be removed without using a tool in the connected state, and the operation of the electric damper 20 can be confirmed.

  Moreover, the heat insulating material 16b which forms the cold air duct 17 of the refrigerator compartment partition member 16 is comprised with the some shaping | molding heat insulating material. Thereby, the refrigerator compartment partition member 16 can be removed without using a tool in a connected state, and frost clogging in the cold air duct 17 can be easily eliminated.
