PURPOSE:To increase food containing efficiency and to improve cleanability by a method wherein the front and rear shelf guide surfaces with a partition wall of the side wall of an inner box with which a cooling air passage is formed are formed in the shape of a protrusion, and are disposed so as to be positioned flush with a partition wall surface. CONSTITUTION:A shelf guide surface 25 of the front part of a partition wall mounting surface formed to a side wall 26 of an inner box and a shelf guide surface 27 of the rear part of the partition wall mounting surface are formed so as to be positioned flush with a partition wall 19 surface. Cold air cooled by a vaporizer 17 flows through a louver 24 to the interior of a refrigerating chamber 12 with the aid of a cooling fan 18. After the cold air cools a food placed on a shelf 31, it is sucked from the lower part of the partition wall and flows through a space 28 formed in the side wall 26 of the inner box in a way that the shelf guide surfaces of the front and the rear part of the partition wall mounding surface are formed in the shape of a protrusion, and is returned to the vaporizer to form a cycle. In this case, no staged part is produced between the inner box and the partition wall, regarding the shape of a shelf, a shelf holding part has no uneven surface and is formed in a flat manner, whereby food containing efficiency is improved, and cleaning of the side wall of the inner box can be facilitated. |
