  The refrigerator 10 includes a cooling device 50 on the rear wall 16 side of the refrigerator compartment 21 as shown in FIG. The cooling device 50 includes a compressor 51, a cooler 52, and a cooler 53. The compressor 51 is provided at the rear wall 16 side, that is, behind the freezer compartment 24 at the lower end of the refrigerator 10. The cooler 52 is provided on the rear wall 16 side of the refrigerator compartment 21. The cooler 53 is provided on the rear wall 16 side of the freezer compartment 24.

Next, the back cover will be described in detail.
The refrigerator 10 includes an upper back cover 60 and a lower back cover 80 between the refrigerator wall 21 and the rear wall 16. That is, the upper back cover 60 and the lower back cover 80 form a cooling passage 61 that houses the cooler 52 between the rear wall 16 and the rear wall 16 behind the refrigerator compartment 21. The upper back cover 60 accommodates not only the cooler 52 but also the fan 54. The upper back cover 60 has an air outlet 62 through which cool air is blown out by the fan 54. The lower back cover 80 has a suction port 81 for sucking cold air. When the fan 54 is driven, the cool air sucked from the suction port 81 is discharged from the air outlet 62 via the cooler 52. The cool air sucked from the suction port 81 is cooled by passing through the cooler 52 and blown out from the blowout port 62 to the refrigerator compartment 21. Thus, the upper back cover 60 and the lower back cover 80 form the cooling passage 61 and accommodate the cooler 52 and the fan 54. A decorative cover 63 is attached to the front side of the upper back cover 60. The decorative cover 63 is provided with an opening 64 for guiding the cold air blown from the air outlet 62 to the refrigerator compartment 21 at the upper end. The upper back cover 60 is provided with a lighting tool (not shown) and a wiring member (not shown) for illuminating the inside of the refrigerator compartment 21. The cooler 52, the fan 54, the illuminator, the wiring member, and the like constitute a functional product as claimed. A defrosting heater may be provided as a functional product between the upper back cover 60 and the rear wall 16.

  The upper back cover 60 has an upper fixed cover 65 and an upper movable cover 66 as shown in FIGS. The upper fixed cover 65 is fixed to the rear wall 16 by, for example, bolts or the like at the fixing portion 67. The fan 54 and the air outlet 62 are provided on the upper fixed cover 65, and are fixed to the rear wall 16 of the main body 11 together with the upper fixed cover 65. The upper movable cover 66 is detachably attached to the upper fixed cover 65. That is, the upper movable cover 66 is attached inside the opening 68 formed by the upper fixed cover 65. The upper movable cover 66 has a claw portion 69, and is held by the upper fixed cover 65 by fitting the claw portion 69 into the upper fixed cover 65 that forms the opening 68. By pushing the upper movable cover 66 in front of the opening formed by the upper fixed cover 65, that is, from the doors 31 and 32 side, the claw portion 69 is locked to the upper fixed cover 65. As a result, the upper movable cover 66 is attached to the upper fixed cover 65. Further, the upper movable cover 66 is made of resin and bends easily. Therefore, the engagement between the claw portion and the upper fixed cover 65 is released by slightly bending the upper movable cover 66. Thereby, the upper movable cover 66 can be easily detached from the upper fixed cover 65. Thus, the upper movable cover 66 can be easily attached to and detached from the upper fixed cover 65 without using a special tool.

  The upper fixing cover 65 has a fixing portion 67 to which a fixing member such as a bolt (not shown) is attached. The upper fixed cover 65 is fixed to the rear wall 16 by a fixing member. Therefore, the upper fixed cover 65 and the upper movable cover 66 are attached to the rear wall 16 in an assembled state. Thereby, the attachment to the rear wall 16 of the upper back cover 60 becomes easy. Further, when the fixing member is removed and the upper fixed cover 65 is removed from the rear wall 16, the upper movable cover 66 fitted in the upper fixed cover 65 is also removed from the rear wall 16. That is, the upper fixed cover 65 and the upper movable cover 66 constituting the upper rear cover 60 are removed by removing the fixing member that fixes the upper fixed cover 65 to the rear wall 16 in the fixing portion 67 of the upper fixed cover 65. Are integrally removed from the rear wall 16.

  The upper fixed cover 65 has a flange 71 on the refrigerator compartment 21 side. Moisture contained in the cold air circulating in the refrigerator compartment 21 is condensed or frosted when passing through the cooler 52. The water that has condensed or formed frost in the cooler 52 is sublimated or melted by rotating the fan 54 while the supply of refrigerant to the cooler 52 is stopped, for example, and is provided on the rear wall 16 of the refrigerator compartment 21. It is collected in the drainage part 72. In addition, the moisture contained in the cool air also adheres as condensation or frost to the refrigerator compartment 21 side of the upper fixed cover 65 adjacent to the cooler 52. The upper fixed cover 65 has a flange 71 on the side of the refrigerator compartment 21 facing the decorative cover 63. The water droplets adhering to the upper fixed cover 65 fall downward along the upper fixed cover 65 due to gravity, are collected by the flange 71, and are discharged to the drain 72. The water collected in the drainage part 72 is guided to the compressor 51 side via a guide passage (not shown). Thereby, the discharged water is converted into water vapor by the heat of the compressor 51 and discharged into the air. The boundary between the upper fixed cover 65 and the upper movable cover 66 is located below the flange 71. Therefore, the water condensed or melted on the upper fixed cover 65 is collected in the flange 71 before reaching the boundary between the upper fixed cover 65 and the lower fixed cover 82. Thereby, even when the upper back cover 60 is divided into the upper fixed cover 65 and the lower fixed cover 82, condensed or melted water is collected in the flange 71 and there is no possibility of leaking from these boundaries. The upper movable cover 66 is located between the shelf plate 44 and the shelf 45 on the rear wall 16 side of the refrigerator compartment 21. Therefore, when removing the upper movable cover 66, it is not necessary to remove the shelf plate 44 and the shelf 45 from the main body 11.

  Similarly, the lower back cover 80 includes a lower fixed cover 82 and a lower movable cover 83. The lower fixed cover 82 is fitted between the partition wall 17 of the main body 11 and the upper back cover 60. The suction port 81 is provided in each of the lower fixed cover 82 and the lower movable cover 83. Further, a deodorizing device 84 is attached to the lower fixed cover 82. The lower movable cover 83 is detachably attached to the lower fixed cover 82, that is, the lower movable cover 83 is attached to the inside of the opening 85 formed by the lower fixed cover 82. The lower movable cover 83 has a claw portion 86, and is held by the lower fixed cover 82 when the claw portion 86 is fitted into the lower fixed cover 82 that forms the opening 85. The lower movable cover 83 is attached by being pushed into the upper fixed cover 65 in the same manner as the upper movable cover 66 described above, and is removed by being slightly bent. Therefore, the lower movable cover 83 can be easily attached to and detached from the lower fixed cover 82 without using a special tool.

  The deodorizing device 84 generates ozone by applying a high voltage between the electrodes to deodorize the sucked air. A temperature sensor 87 is provided in the vicinity of the deodorizing device 84. The temperature sensor 87 detects the temperature of the refrigerator compartment 21. The temperature sensor 87 also constitutes a functional product. The deodorizing device 84 is applied with a high voltage as described above. Therefore, covering the deodorizing device 84 with the lower fixed cover 82 prevents the user's hand from touching the deodorizing device 84. The temperature sensor 87 is provided in the vicinity of the opening 85 of the lower fixed cover 82. Since the temperature sensor 87 operates at a low voltage, even if it is provided in the vicinity of the opening 85 of the lower fixed cover 82, there is no possibility that the safety is lowered. On the other hand, by disposing the temperature sensor 87 in the vicinity of the opening 85 of the lower fixed cover 82, the temperature sensor 87 can be easily replaced or repaired. As a result, the maintainability of the temperature sensor 87 is improved.

  Furthermore, the refrigerator 10 includes a back cover 90 on the rear wall 16 side in the ice making chamber 22, the switching chamber 23, and the freezing chamber 24 as shown in FIGS. That is, the back cover 90 forms a cooling passage 91 that houses the cooler 53 between the ice making chamber 22, the switching chamber 23, and the freezing chamber 24 and the rear wall 16. As described above, the refrigerator 10 includes the cooler 52 that cools the refrigerator compartment 21 and the cooler 53 that cools the ice making chamber 22, the switching chamber 23, and the freezer compartment 24. As shown in FIG. 5, the back cover 90 houses not only the cooler 53 but also the fan 56 and the defrosting heater 57. The back cover 90 has a two-layer structure, and a cooling passage 91 is formed between the rear cover 90 and the rear wall 16, and a ventilation passage 92 is formed on the front side. The back cover 90 has air outlets 93, 94, 95, 96, 97 for blowing out cool air and an inlet 98 for sucking in cold air. Air outlets 93, 94, 95, 96, and 97 are provided corresponding to the ice making chamber 22, the switching chamber 23, and the freezing chamber 24 by connecting to the air passage 92. The suction port 98 is provided at the lower end of the back cover 90 adjacent to the air outlet 97 of the freezer compartment 24. When the fan 56 is driven, the cool air sucked from the suction port 98 passes from the air outlets 93, 94, 95, 96, 97 via the cooler 53 provided in the cooling passage 91 and the air passage 92. Discharged. The cold air drawn from the suction port 98 is cooled by passing through the cooler 53 provided in the cooling passage 91, and the ice making chamber 22 is connected to each of the outlets 93, 94, 95, 96, 97 connected to the blower passage 92. Then, it blows out to the switching chamber 23 or the freezing chamber 24. The defrosting heater 57 generates heat when energized and melts frost adhering to the back cover 90. Thus, the back cover 90 forms the cooling passage 91 and houses the cooler 53, the fan 56, and the defrosting heater 57. The cooler 53, the fan 56, and the defrosting heater 57 constitute a functional product as claimed.

  The back cover 90 has a fixed cover 101 and a movable cover 102 as shown in FIGS. 6 and 7. The fixed cover 101 is fixed to the rear wall 16 with a bolt or the like, for example. The movable cover 102 is detachable from the fixed cover 101. That is, the movable cover 102 is held by the fixed cover 101 by being fitted inside the lower end portion of the fixed cover 101. As shown in FIGS. 8 and 9, a bolt 103 as a support member is attached to the rear wall 16 of the main body 11. The bolt 103 is fixed to the rear wall 16 of the main body 11. A packing 104 is attached between the bolt 103 and the rear wall 16. The packing 104 is made of a flexible material such as rubber. As shown in FIG. 9, the movable cover 102 has a hole 105 at a portion corresponding to the bolt 103. The inner diameter of the hole 105 is slightly larger than the outer diameter of the packing 104. Since the packing 104 is flexible as described above, when the movable cover 102 is pressed from the front, the packing 104 is deformed radially inward of the hole 105 and inserted into the hole 105. Accordingly, the movable cover 102 is attached integrally with the fixed cover 101 inside the fixed cover 101. On the other hand, when the movable cover 102 is pulled forward, the flexible packing 104 is deformed and the movable cover 102 is removed from the bolt 103. As a result, the movable cover 102 is removed from the rear wall 16 and the fixed cover 101. Thus, the movable cover 102 can be easily attached to and detached from the fixed cover 101 without using a special tool or the like.

  As shown in FIG. 6, the fixed cover 101 has a fixed portion 107 to which a fixing member 106 such as a bolt is attached, in addition to the hole portion 105 of the movable cover 102. The fixed cover 101 is fixed to the rear wall 16 by a fixing member 106. Therefore, the fixing member 106 is removed to remove the fixing cover 101 from the rear wall 16 and the fitting of the hole 105 and the packing 104 is released by pulling the movable cover 102 so that the fixing cover 101 is fitted. The movable cover 102 is also removed from the rear wall 16 together with the fixed cover 101. That is, the fixed cover 101 and the movable cover 102 constituting the back cover 90 are integrated by removing the fixing member 106 that fixes the fixed cover 101 to the rear wall 16 at the fixing portion 107 of the fixed cover 101. And removed from the rear wall 16.

  The movable cover 102 integrally has an intake port 98 that sucks in the circulating cold air and air outlets 96 and 97 that blow out the cold air into the freezer compartment 24. Thereby, the movable cover 102 partitions the passage through which the cool air sucked from the suction port 98 flows and the passage through which the cool air blown out from the air outlets 96 and 97 flows by a partition wall (not shown). That is, the movable cover 102 divides the outlets 96 and 97 and the suction port 98 side by itself by a partition wall that the movable cover 102 has. Therefore, the outlets 96 and 97 side and the inlet 98 side are reliably partitioned by the partition wall. As a result, mixing of cool air having a relatively high temperature sucked from the suction port 98 and cool air having a relatively low temperature blown out from the air outlets 96 and 97 is reduced.

Temperature sensors 99 are provided in the vicinity of the air outlet 95 and the air outlet 96, respectively. The temperature sensor 99 detects the temperature of the freezer compartment 24. The temperature sensor 99 is provided on the movable cover 102 and is removed from the fixed cover 101 together with the movable cover 102. Since the operating voltage of the temperature sensor 99 is set low, even if it is provided on the movable cover 102, the safety is not lowered.
The upper end of the movable cover 102 is located slightly below the partition wall 18. Therefore, the movable cover 102 can be removed from the fixed cover 101 by removing the freezing container 35 accommodated in the freezer compartment 24. That is, removal of the movable cover 102 provided on the rear wall 16 side of the freezer compartment 24 is not hindered by the partition wall 18.

  As described above, in the embodiment of the present invention, the upper fixed cover 65 and the lower fixed cover 82 cover a part of the rear wall 16 in the refrigerator compartment 21. Therefore, functional products such as the cooler 52, the fan 54, the deodorizing device 84, the temperature sensor 87, the lighting fixture, and the wiring member provided in the cooling passage 61 are covered with the upper fixed cover 65 and the lower fixed cover 82. . The fixed cover 101 covers a part of the rear wall 16 in the freezer compartment 24. Therefore, functional components such as the cooler 53, the fan 56, and the defrosting heater 57 provided in the cooling passage 91 are covered with the fixed cover 101. Thereby, a user's hand does not touch functional goods, such as the coolers 52 and 53, the fans 54 and 56 deodorizing apparatus 84, and the heater 57 for defrosting. On the other hand, the upper movable cover 66 is detachably fitted to the upper fixed cover 65, the lower movable cover 83 is detachably fitted to the lower fixed cover 82, and the movable cover 102 is detachably fitted to the fixed cover 101. Therefore, the upper movable cover 66, the lower movable cover 83, and the movable cover 102 are all easily removed from the upper fixed cover 65, the lower fixed cover 82, or the fixed cover 101 without using a tool or the like. The upper movable cover 66, the lower movable cover 83, and the movable cover 102 constitute a part of the upper back cover 60, the lower back cover 80, or the back cover 90, respectively. Therefore, by removing only the upper movable cover 66, the lower movable cover 83, or the movable cover 102 from the upper back cover 60, the lower back cover 80, or the back cover 90, respectively, for example, it is accommodated between the rear wall 16 and the rear cover 16. The temperature sensor 87 and the temperature sensor 99 that are present can be repaired or replaced. As a result, it is possible to remove the upper movable cover 66, the lower movable cover 83, or the movable cover 102 only by removing a minimum number of parts. Therefore, handling can be facilitated while improving safety.

  In one embodiment of the present invention, a refrigerator 52 is provided in the refrigerator compartment 21, and a cooler 53 is provided in the freezer compartment 24. On the other hand, the upper back cover 60 and the lower back cover 80 are provided in the refrigerator compartment 21, and the back cover 90 is provided on the freezer compartment 24 side. Thus, the upper back cover 60, the lower back cover 80, and the back cover 90 are provided for each room to which cold air cooled by the respective coolers 52 and 53 is supplied. Therefore, even when the air cooled by the plurality of coolers 52 or the coolers 53 is individually supplied to the refrigerator compartment 21 or the freezer compartment 24, the upper back cover 60, the lower back cover 80, and the back cover 90 are movable with the fixed side. Can be divided into side and side.

  In one embodiment of the present invention, the movable cover 102 provided in the freezer compartment 24 is attached to the main body 11 to which the fixed cover 101 is fixed by being fitted into the bolt 103 via the hole 105. The bolt 103 is fixed to the rear wall 16 of the main body 11. Therefore, even when the movable cover 102 is removed, the bolt 103 remains on the rear wall 16 of the main body 11. A packing 104 is provided on the bolt 103, and the movable cover 102 is attached and detached using the flexibility of the packing 104. Therefore, the movable cover 102 can be easily removed while supporting the movable cover 102 together with the fixed cover 101 on the main body 11.

  In one embodiment of the present invention, the movable cover 102 provided in the freezer compartment 24 is integrally formed with air outlets 96 and 97 and an inlet 98. Therefore, the cool air sucked from the suction port 98 and the cool air blown from the air outlets 96 and 97 are partitioned by an integral movable cover 102. Therefore, it is easy to secure a sealing property between the cool air having a relatively high temperature sucked from the suction port 98 and the cool air having a relatively low temperature blown out from the air outlets 96 and 97, and mixing of the cool air can be reduced. .

  In one embodiment of the present invention, a fixing portion 67 is provided on the upper fixing cover 65, and a fixing portion 107 is provided on the fixing cover 101. Therefore, when the upper fixed cover 65 and the upper movable cover 66 are integrally attached in the refrigerating chamber 21, the upper rear cover 60 and the upper fixed cover 65 are operated by operating the fixing portion 67 of the upper fixed cover 65. The upper movable cover 66 is integrally removed from the main body 11. Further, when the fixed cover 101 and the movable cover 102 are integrally attached in the freezer compartment 24, the rear cover 90 can be moved between the fixed cover 101 and the movable cover 102 by operating the fixed portion 107 of the fixed cover 101. It is integrally removed from the main body 11. Therefore, the upper back cover 60 can be easily attached and detached and the back cover 90 can be easily handled.

  In one embodiment of the present invention, the boundary between the upper fixed cover 65 and the upper movable cover 66 provided in the refrigerating chamber 21 is located below the flange 71 that guides the condensed water in the direction of gravity. . Therefore, the water condensed by the upper fixed cover 65 disposed close to the cooler 52 is guided to the collar portion 71 without falling from the upper fixed cover 65 side to the upper movable cover 66 side. Accordingly, it is possible to reduce water leakage to the refrigerator compartment 21 and cold air leakage.

  In the embodiment of the present invention, the upper movable cover 66 is provided between the shelf plate 44 and the shelf 45. Therefore, the upper movable cover 66 is removed from the upper fixed cover 65 without removing the shelf plate 44 and the shelf 45 from the main body 11. Therefore, the upper movable cover 66 can be easily handled. Further, the movable cover 102 has an upper end located slightly below the partition wall 18.
