  The illumination device 33 is provided so as to be positioned in front of the front edge of the cover plate 15 when the cover plate 15 of the low-temperature storage chamber 16 is opened so as to improve the irradiation property when the cover plate 15 is opened. Considered.

  Furthermore, a cold air duct 19 for supplying the cold air generated by the cooler 10 to the cold room 3 is provided on the back surface of the cold room 3. As shown in FIGS. 3 and 4, the cold air duct 19 is provided vertically at a substantially central portion of the back surface of the refrigerator compartment 3 in the vertical direction, and a duct cold air inlet portion 21 connected to the cold air passage portion 20 from the cooling chamber 9. And a duct lower portion 22 connected thereto, and cold air outlets 23 that open to the spaces partitioned by the storage shelf 14 are provided on the front surface and the left and right side surfaces, respectively.

  The cool air passage portion 20 from the cooling chamber 9 is led out from the central portion of the cooling chamber 9 as shown by the broken line in FIG. 4, and the cool air efficiently cooled in the central portion of the cool cooler is supplied to the cool air duct 19. It comes to be supplied.

  Further, as shown by the broken line in FIG. 4, a cold air return port 24 is provided in the uppermost back portion of the refrigerator compartment 3. The cold air return port 24 opens into the low temperature storage chamber 16 and communicates with the refrigerating room space below the low temperature storage room 16 via the cold air return duct 25, and the cold air in the refrigerating room 3 is left and right of the cooling room 9. It is configured to return to both side portions, that is, both side portions of the cooler 10.

  Here, in the cold air duct 19, as shown in FIG. 5, a damper 26 for controlling the cold air supply is incorporated in the duct cold air inlet portion 21, and the wall thickness of the duct cold air inlet portion 21 on the side of the refrigeration room is the lower portion of the duct. It is formed to be thicker than the side wall thickness of 22 refrigerator compartment surfaces. In this embodiment, the wall thickness of the duct lower portion 22 is 20 mm to 10 mm, and the wall thickness of the lowermost end portion of the duct cold air inlet portion 21 is 40 mm to 50 mm.

  Further, the wall of the duct cold air inlet portion 21 on the side of the refrigerating room surface is inclined so that the wall surface protrudes forward so that the wall thickness further increases as it goes upward. The closer to the cool air passage portion 20, the thicker the wall thickness.

Also, the duct cold air inlet portion 21 and the duct lower portion 22 of the cold air duct 19 are shown in FIG.
As shown in FIG. 5, the cool air duct 19 is configured by combining and combining these as separate parts. The duct cold air inlet portion 21 and the duct lower portion 22 are each composed of a duct main body portion 19a formed of a heat insulating material such as polystyrene foam, and a duct cover 19b covering the inside of the refrigerator main body 19a.

  Further, the cold air duct 19 has a closed surface without providing the cold air outlets on both sides of the duct cold air inlet portion 21 facing the uppermost low temperature storage chamber 16 among the cold air outlets 23 provided on both side surfaces thereof, as shown in FIG. The cold air outlet provided in the front portion is hereinafter referred to as a cold air outlet 23a for a low temperature storage room). Further, as shown in FIG. 5, a wind shielding plate 27 protruding toward the front (in the refrigerator compartment side) is provided at a lower portion of the cold air outlet 23a for the low temperature storage room.

  In FIG. 6, 28 is a sealing material for the damper mounting portion, and 29 is a deodorizing filter provided in the cool air return duct 25.

  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  In the refrigerator, cold air is generated in the cooling chamber 9 at the back of the freezer compartment 2. This cold air flows from the duct cold air inlet portion 21 to the cold air duct 19 through the cold air passage portion 20, and is cooled at a low temperature as indicated by solid line arrows in FIG. 4 from the cold air outlets 23 and 23a on the front surface and both sides of the cold air duct 19. It is supplied into the refrigerator compartment 3 including the storage compartment 16.

  The cold air supplied into the refrigerator compartment 3 cools the food in each space of the low temperature storage compartment 16 and the refrigerator compartment 3, and as shown by the broken line arrows in FIG. Then, the circulation after being cooled by the cooler 10 and flowing to the refrigerating chamber 3 again is repeated.

  Here, since the refrigerator compartment 3 partitions the refrigerator compartment space into a plurality of upper and lower spaces by a plurality of storage shelves 14, the height of each space can be changed by changing the height position of the storage shelves 14. Different foods can be stored.

  Further, in this refrigerator, a storage box 18 incorporated in one of a plurality of spaces partitioned by the storage shelf 14, in this example, the lowermost space, of the support member 31 a provided in the upper part of the refrigeration room space It can be incorporated by moving to the auxiliary rail portion 17a. That is, the position of the pull-out storage space 18a can be changed, and the usability of the user who frequently uses the pull-out storage space 18a can be greatly improved.

  For example, in this embodiment, the refrigerator compartment 3 is provided with the rail portion 17 at the lowermost portion of the refrigerator compartment and the auxiliary rail portion 17a is provided at the support member 31a at the upper portion of the refrigerator compartment. It can be changed above and below the refrigerated room.

  Therefore, in this example, the drawer-type storage space 18a provided at the lowermost part of the refrigerator compartment is changed to the vicinity of the user's waist position so that the food in the drawer-type storage space 18a can be taken out without bending the waist. Can do. Therefore, even if the food stored in the drawer-type storage space 18a formed by the storage box 18 is a heavy food such as canned beer, it can be easily put in and out, and the user who frequently uses the drawer-type storage space 18a. Convenience is greatly improved.

  Thus, in this refrigerator, the position of the drawer-type storage space 18a can be changed in the same manner as the change of the height position of each space partitioned by each storage shelf 14, and can be used according to the user's preference. Greatly improved.

  Further, in this embodiment, the part where the storage box 18 is installed is the lowermost part of the refrigeration room, and the back surface of the storage box 18 protrudes greatly forward by the machine room 12, so that the storage provided in the space part at the lowermost part of the refrigeration room. The box 18 tends to be a small one with a short front and rear length. However, in this embodiment, since the door pocket 30 is not provided on the inner surface of the door 8 facing the space part at the lowermost part of the refrigerator compartment, the front and rear lengths of the storage box 18 installed in the part are ensured to be large. And the internal volume of the drawer-type storage space 18a can be increased.

  That is, even if the portion where the storage box 18 is installed protrudes greatly toward the refrigeration room, such as the machine room 12 provided for installing the compressor 13, there are no door pockets on the inner surface of the door, so that the storage box. The front-rear length of 18 can be increased, and the volume of the drawer-type storage space 18a can be increased.

  As a result, more food can be stored in the drawer-type storage space 18a formed by the storage box 18, and usability is improved.

  On the other hand, there is a door pocket 30a in the door inner surface portion on the side where the installation position of the storage box 18 is changed, in this example, the door inner surface portion facing the space on the side where the auxiliary rail portion 17a is provided. Even if there is, the back of the refrigerator compartment space where the door pocket 30a exists does not protrude as much as a plane or the machine room 12, so that the protrusion of the door pocket 30a replaces the protrusion margin generated by the machine room 12. It becomes. Therefore, the storage box 18 can be repositioned without any problem, that is, without being replaced with another storage box having a different size, and the storage box 18 can be shared while securing a storage capacity, thereby improving usability.

  Moreover, the refrigerator compartment 3 of the refrigerator shown in this embodiment can be used by changing the usage of the drawer-type storage space 18a by changing the installation position of the drawer-type storage space 18a in the storage box 18. Usability is further improved.

  More specifically, the refrigerating chamber 3 has one of the space portions in which the storage box 18 can be installed. In this example, the cold air duct 19 is located in the space above the auxiliary rail portion 17a and the cold air outlet 23 is provided. Therefore, if the storage box 18 is installed above the auxiliary rail portion 17a, the drawer-type storage space 18a in the storage box 18 is filled with the cold air blown out from the cold air outlet 23. The temperature is slightly lower than that.

  On the other hand, the drawer-type storage space 18a in the storage box 18 installed at the lowermost part of the refrigerating room has a machine room 12 on the back surface and no cold air outlet, so that the auxiliary rail portion has substantially the same temperature as the refrigerating room space. The temperature is slightly higher than when the storage box 18 is installed in the space above 17a.

  Accordingly, the drawer-type storage space 18a of the storage box 18 can be properly used as a storage space with different cooling temperatures, and various foods can be stored in a refrigerator, further improving usability.

  For example, when the storage box 18 is installed at the lowermost part of the refrigerator compartment, the drawer-type storage space 18a is used as a vegetable storage room, and when the storage box 18 is installed above the auxiliary rail portion 17a, the drawer-type storage space. 18a can be used as a storage room for meat, fish and the like, and various foods can be refrigerated at temperatures suitable for each.

Thus, in this refrigerator, the usage purpose of the drawer-type storage space 18a spreads, and usability is greatly improved.

  The storage shelves 14a and 14b located at the upper part of the storage box 18 are arranged so as to be close to and cover the upper opening of the storage box 18, so that the drawer-type storage in the storage box 18 is provided. The space 18a can be more effectively made into a cold room or a storage space having a relatively high temperature, and various foods can be stored in a cooled state in a more optimal state.

  As described above, the refrigerator can change the position of the drawer-type storage space 18a and improve usability. However, the following effects are also provided, and will be described.

  That is, in this refrigerator, the cold air duct 19 for supplying cold air to the refrigerator compartment 3 is connected to the cold air passage portion 20 and the duct cold air inlet portion 21 adjacent thereto is strongly touched by the low temperature cold air from the cold air passage portion 20 first. Cooling is likely to cause condensation.

  However, since the wall thickness of the duct cold air inlet portion 21 is thicker than the wall thickness of the duct lower portion 22, the temperature drop due to the low temperature cold air from the cooling chamber 9 is suppressed and the surface temperature is kept relatively high. be able to. Therefore, even if the used area is a hot and humid area and a relatively large amount of outside air enters the refrigerator compartment 3, the condensation at the duct cold air inlet portion 21 is suppressed. Can do.

  In particular, the duct cold air inlet portion 21 has a portion located above the damper 26 that is always in communication with the cooling chamber 9 and is always strongly cooled by low temperature cold air and tends to cause dew condensation. Since the wall thickness of the upper part is made thicker than 26, the temperature of the entire duct cold air inlet part 21 can be maintained relatively high, and the occurrence of condensation can be reliably suppressed.

  Further, since the cold air duct 19 has a thick wall thickness only for the duct cold air inlet portion 21, only the duct cold air inlet portion 21 has a large allowance to protrude into the refrigerating chamber 3, and the duct lower portion 22 below it is smaller. The number can be reduced as in the conventional case. Therefore, the reduction in the volume of the refrigerator compartment caused by increasing the wall thickness can be minimized, and the volume of the refrigerator compartment 3 is secured by minimizing the volume reduction while preventing condensation on the surface of the cold air duct 19. can do.

  In particular, in this embodiment, the inner surface side of the refrigerator cold air inlet portion 21 of the duct cold air inlet portion 21 is configured such that the wall surface is inclined so that its wall thickness increases toward the upper side, that is, the cooling chamber 9 side. Compared with the case where the wall thickness of the entire duct cold air inlet portion 21 is increased, the ratio of reducing the volume of the refrigerator compartment can be reduced, and the temperature in the portion where the cold air in the cooling chamber 9 is always present and is particularly likely to become extremely low is lowered. It is possible to effectively secure the refrigerator compartment volume while efficiently relieving.

  In addition, since the upper space where the duct cold air inlet portion 21 of the refrigerator compartment 3 is located is covered with the cover plate 15 as the low temperature storage chamber 16, the outside air is not opened unless the cover plate 15 is opened even if the door 8 of the refrigerator compartment 3 is opened. Does not touch the duct cold air inlet portion 21. Therefore, even if the door 8 is opened and closed and the outside air enters the refrigerating chamber 3, the opportunity for the outside air to touch the duct cold air inlet portion 21 can be greatly reduced. As a result, even if the door 8 is often opened and closed, or the opening time of the door is long, etc., the high temperature and high humidity outside air entering the refrigerator compartment 3 may increase. It is possible to prevent the occurrence of dew condensation by suppressing the touching to prevent the dew condensation.

Further, since the cold air duct 19 is formed by combining and connecting the duct cold air inlet portion 21 and the duct lower portion 22 as separate parts, the duct cold air inlet portion 21 is connected to the duct lower portion 22 at this connecting portion. The cold heat transfer number can be cut off. Therefore, it is possible to greatly reduce the cold energy transfer from the duct cold air inlet portion 21 that is strongly cooled by the low temperature cold air to the duct lower portion 22, and to prevent a temperature drop due to the cold heat transfer of the duct lower portion 22, thereby condensing the entire cold air duct 19. Prevention can be made more reliable.

  Furthermore, in this embodiment, since the wind shield plate 27 is provided in the lower portion of the cool air duct 19 at the lower portion of the cool air outlet 23a, the cool air blown out from the cool air outlet 23a is stored at a lower temperature. It is possible to prevent the duct lower portion 22 from being cooled by flowing down just below the room cold air outlet 23a. Therefore, it is possible to prevent the duct lower portion 22 of the cold air duct 19 from being cooled strongly by this low-temperature cold air, causing the temperature to drop and causing dew condensation in that portion.

  As described above, the refrigerator shown in this embodiment can prevent the occurrence of dew condensation over the entire cold air duct 19 as well as the duct cold air inlet portion 21, and can be a higher quality refrigerator.

  As mentioned above, although the refrigerator concerning this invention was demonstrated using the said embodiment, this invention is not limited to this.
