Further, the glass plate 124 is colorless and transparent, so that the food stored in the upper container 72 can be seen through.

(4) Storage and withdrawal state of upper container 72 The storage and withdrawal states of the upper container 72 in the chilled chamber 42 will be described.

  First, a state where the door 14b of the refrigerator compartment 14 is closed and the upper container 72 and the lower container 74 are stored in the chilled chamber 42 will be described. As shown in FIGS. 3 and 9, the front surface 80 of the upper container 72 and the front surface of the lower container 74 are positioned side by side in the vertical direction, and the space above the front of the upper container 72 is covered with a cover 90. At this time, the contact 130 of the rotary arm 128 that protrudes rearward from the cover 90 is located on the inner side (rear side) of the bent portion 102 at the front end of the regulating piece 100. The door pocket 44 provided on the rear surface of the door 14b of the refrigerator compartment 14 is located in front of the chilled chamber 42. The rear surface of the door pocket 44 is the front of the cover 90, the front surface 80 of the upper container 72, and the front surface of the lower container 74. Is located. The same applies to the right side of the upper container 72.

  Second, when the user opens the door 14b, the chilled chamber 42 appears as shown in FIG. Therefore, the user places a hand on the handle portion 86 of the upper container 72 and pulls only the upper container 72 forward. As shown in FIG. 10, the rail protrusions 106 and 120 of the upper container 72 move forward along the rails 61 and 61. Further, since the restricting piece 100 also moves forward, the contact 130 located inside the bent portion 102 moves relatively rearward along the lower side of the restricting piece 100, and the cover 90 moves the rotating shaft 126 together with it. Rotate upward to the center and begin to open.

  Thirdly, when the user continues to pull the upper container 72 forward, the contact 130 of the cover 90 moves further rearward along the lower part of the restriction piece 100 as shown in FIG. At this time, since the restriction piece 100 is upward as it goes rearward (that is, downward as it goes forward), the contact 130 moves upward and the cover 90 opens more. When the contact 130 moves between the restriction piece 100 and the guide portion 94, the contact 130 slides on the upper surface of the guide portion 94 or the lower surface of the restriction piece 100 depending on how the upper container 72 is pulled out. That is, a portion where the contact 130 is present is a space between the regulation piece 100 and the guide portion 94.

  Fourth, when the user pulls the upper container 72 forward, the contact 130 of the cover 90 passes the rear end of the restriction piece 100 as shown in FIG. It falls on the part 94. The contact 130 of the cover 90 moves backward on the guide portion 94. Further, before the contact 130 reaches the flange portion 96 from the rear end portion of the guide portion 94, a protrusion is provided at the rear end portion of the rail protrusion 120 so that the upper container 72 cannot be pulled out. Yes.

  Further, the right side contact 78 of the upper container 72 also moves in the same manner as the left side by the guide portion 110 and the restriction piece 116. However, since the rear end portion of the restriction piece 116 is shorter than the left restriction piece 100, most of the movement moves on the right guide portion 110.

  When the user stores the upper container 72, the contact 130 moves forward opposite to the above.

  Thereby, the upper container 72 can be pulled out and stored while the cover 90 is smoothly opened and closed.

(5) When a foreign object is caught between the upper container 72 and the cover 90 Next, a case where a foreign object such as a finger is caught between the front surface 80 of the upper container 72 and the cover 90 will be described with reference to FIGS. .

  As shown in FIGS. 13 and 14, since the space 104 is provided between the bent portion 102 of the restricting piece 100 and the guide portion 94, the user can contact the contact at the tip of the rotating arm portion 128 of the cover 90. 130 is moved forward through the space 104. Further, as shown in FIG. 15, since the cover 90 can be rotated upward, the user can easily remove the foreign matter. In particular, since the step piece 114 is provided continuously from the front end portion of the guide portion 94, the space 104 is wider and the contact 130 is easily pulled out.

(6) When the door 14b is closed vigorously Next, the upper container 72 and the cover 90 when the user closes the door 14b vigorously will be described with reference to FIGS.

  When the user closes the door 14b with the upper container 72 pulled out forward, the rear surface of the door pocket 44 hits the front surface 80 of the upper container 72, and the upper container 72 is pushed backward vigorously. At this time, the contact 130 is located between the guide portion 94 and the restriction piece 100, but when the restriction piece 100 moves rearward, the contact 130 is also moved upward by the bent portion 102 at the front end portion of the restriction piece 100. As the container 72 moves, the cover 90 moves rearward and closes vigorously, so that the lower end of the cover 90 does not cover the door pocket 44 as in the prior art.

(7) State when Attaching Cover 90 A case where the cover 90 is attached will be described with reference to FIGS. 19 and 12.

  First, the user attaches the pair of left and right rotating shafts 126 of the cover 90 to the pair of left and right support arm portions 71 of the ceiling surface 58.

  Second, as shown in FIG. 19, the user turns the cover 90 to the uppermost position around the rotation shaft 126. In this case, the contact 130 is placed on the restriction piece 100.

  Third, when the user pulls the upper container 72 forward, even if the contact 130 is positioned on the restriction piece 100, the contact 130 is placed on the guide portion 94 from the rear end of the restriction piece 100. As shown in FIG. 12, the contact 130 moves to the normal position.

  Fourth, when the user moves the upper container 72 backward again, the cover 90 closes in a normal state.

(8) Effect According to the above embodiment, the cover 90 opens and closes smoothly when the upper container 72 is pulled out or stored from the chilled chamber 42.

  Further, even if a foreign object is sandwiched between the cover 90 and the upper container 72, the cover 90 can be pulled up, so that the foreign object can be easily removed.

  Even if the door 14 b is closed with the upper container 72 pulled out, the contact 90 of the cover 90 is pushed backward by the bent portion 102 of the restricting piece 100, so that the cover 90 gets on the upper surface of the door pocket 44. There is nothing.

  Further, even when the cover 90 is attached, the contact 90 can be dropped from the restriction piece 100 onto the guide portion 94 to return to the normal state, so that the cover 90 can be easily attached.

  Further, since the contact 130 moves outside the upper container 72, it does not come into contact with the food in the upper container 72 and does not damage the food.

  In addition, since the cover 90 includes a glass plate, it is heavier than the resin, and when glass having high strength is used, the glass itself is broken or the glass stored in the stored product stored on the door pocket 44 side. A chilled chamber 42 using glass can be realized while preventing damage.

(9) Modified Example In the above embodiment, the long restricting piece 100 is provided only on the left bulging portion 92 of the upper container 72, but instead, a long restricting piece 116 may be provided only on the right side surface 78. Long restricting pieces 100 and 116 may be provided on both side surfaces.

  In the above embodiment, the upper and lower two-stage upper and lower containers 72 and 74 are arranged inside the chilled chamber 42. Instead, only one chilled container is provided, and this chilled container is provided with the upper container of the above embodiment. A structure similar to that of the container 72 may be provided.

  Although one embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
