  The size of the first recess 71 gradually decreases in the refrigerator width direction (second direction) toward the rear (first direction), that is, in the refrigerator width direction (second direction) toward the rear (first direction). It is inclined so that the opposing side walls are narrowed. Further, in this example, the first recess 71 is inclined so that the side wall facing in the direction (vertical direction) orthogonal to the first direction and the second direction also gradually decreases toward the rear (first direction). doing.

  The difference δ (the length in the second direction at the opening of the first recess 71 (in other words, the interval between the side walls facing the second direction in the opening) X and the length Y of the plug case 66 in the second direction δ ( = XY) is the clearance amount (movement amount) that the chilled container 19 can move in the refrigerator width direction (second direction) by the clearance formed between the moving rails 40, 40 and the fixed rails 42, 42. It is set large.

  The bottom of the first recess 71 is provided with a suction plate 73 and a pair of electrode pins 74, 74 protruding from both sides of the suction plate 73, and the power feeding side connection portion 65 is disposed in the first recess 71.

While being in contact with the contact point 68a of the electrode body 68, the metal plate 67b of the magnet assembly 67 is attracted to the attracting plate 73 so that the electrical connection state is maintained. When the pair of electrode pins 74, 74 contact the contact 68 a of the electrode body 68, the power supply unit 75 and the power storage unit 61 provided in the refrigerator body 10 are electrically connected, and the power output from the power supply unit 75 is stored. Is supplied to the unit 61 and stored in the power storage unit 61.

  Further, when the chilled container 19 is stored in the chilled chamber 20, the power storage unit 61 protruding from the rear wall 19 a of the chilled container 19 is stored in the second recess 72 without contacting the duct plate 6.

  In the refrigerator 1 of the present embodiment, even if the chilled container 19 provided movably with respect to the refrigerator main body 10 includes the lighting device 60, the chilled container is connected to the chilled container from the power supply side connecting portion 65 provided in the refrigerator main body 10. Power can be supplied to the power storage unit 61 via the power receiving side connection unit 63 provided in the power supply 19.

  In addition, since the power receiving side connecting portion 63 and the power feeding side connecting portion 65 include the magnet assembly 67 and the suction plate 73, even if the position of the chilled container 19 is likely to vary due to movement, the magnet assembly 67 and It is electrically connected to the suction plate 73 by a magnetic suction force generated.

  Further, in this embodiment, the difference δ between the length X in the second direction at the opening of the first recess 71 provided with the power supply side connection portion 65 and the length Y in the refrigerator width direction of the plug case 66 is: The clearance is set larger than the clearance formed between the moving rails 40, 40 and the fixed rails 42, 42. Therefore, when the chilled container 19 drawn forward is stored in the chilled chamber 20, the position of the chilled container 19 is moved in the second direction by the clearance formed between the moving rails 40, 40 and the fixed rails 42, 42. Even if they are displaced, the power receiving side connecting portion 63 provided in the chilled container 19 is positioned inside the opening of the first recess 71, and a large magnetic attraction force is generated between the magnet assembly 67 and the attraction plate 73. Thus, the power receiving side connecting portion 63 and the power feeding side connecting portion 65 can be more reliably electrically connected.

  In addition, in the present embodiment, the first recess 71 is inclined so that the distance between the side walls facing the refrigerator width direction becomes narrower toward the rear. Therefore, when the chilled container 19 moves rearward, the power supply side connection is made. Since the plug case 66 of the portion 65 is guided by the side wall of the first recess 71 to the bottom of the first recess 71 where the suction plate 73 and the electrode pin 74 are provided, the power receiving side connection portion 63 and the power feeding side connection portion 65 are provided. Can be securely and smoothly electrically connected.

  Moreover, in this embodiment, since the illuminating device 60 is provided in the back wall 19a of the chilled container 19, and illuminates the inside of the chilled container 19 from the back, the light from the interior lamp provided in the refrigerator compartment 11 and the exterior is received. The rear side of the chilled container 19 that is difficult to reach and easily becomes a blind spot can be effectively illuminated, and the visibility of the user can be improved. In the present embodiment, the LED 62 of the lighting device 60 is provided on the rear wall 19a of the chilled container 19, but the rear side of the chilled container 19 that tends to be a blind spot even if provided on the rear side from the center in the front-rear direction of the chilled container 19 is provided. It can be effectively illuminated.

  In the present embodiment, the case where the chilled container 19 is provided as the movable part has been described. However, in addition to the chilled container 19, for example, the doors 11a, 12a, 13a, and 15a, the shelf board 16, the automatic ice making machine 13c, and the storage The movable parts such as the containers 12 b to 15 b and the water storage tank 18 may be provided so as to be movable with respect to the refrigerator main body 10.

  Moreover, although this embodiment demonstrated the case where it provided LED62 of the illuminating device 60 as a functional component, for example besides the LED62, the operation panel which sets the driving | operation of the refrigerator 1, the display part which displays a driving condition, Any part provided on a movable part that operates by electric power, such as a photographing device that photographs the interior of the storage, or a deodorization and sterilization apparatus that deodorizes or disinfects the interior of the storage, may be used.
