った時である。The upper air duct 41 is formed to extend over the inner surface of the ceiling wall of the upper heat insulating box 6, and the air outlet 43 is disposed at the front of the inner surface of the ceiling wall. A blower device 44 is formed at a corner between the inner surface of the ceiling wall and the inner surface of the back of the upper blower duct 41. The blowing of cold air from the cooling @ 21 into the upper storage box body 2 involves pushing (blowing) cold air into the lower air duct 27 and the upper air duct 41 by the air blower 23, and the blowing of the cold air into the upper air duct 41 by the air blower 44. This is done by sucking up the back part. When the distance between the lower ventilation duct 27 and the upper ventilation duct 41 is long and the ventilation resistance is large, cold air can be efficiently blown to a high place using the small ventilation device 23.44. Since the upper air duct 41 is bent in the middle, the air blowing resistance increases, but the air blowing resistance due to the gravity of the cold air with increased specific gravity can be reduced, and the air blowing devices 23 and 44 can be stopped to prevent the backflow of cold air. It is preventable. Air blower 23.
44 is stopped when the temperature sensor detects that the internal temperature of the upper storage box body 2 and the lower storage box body 3 has reached a predetermined value.
This is when the cooler 21 is frosted and the defrosting operation is started.

実施例では冷気案内通路45を凹所にて形成している。The upper return duct 42 opens at the lower center corner of the rear surface of the upper heat insulating box 6. A cold air guide passage 45 communicating with the upper return duct 42 is formed at the rear of the inner bottom surface of the double-insulated box 6. The cold air guide passage 45 extends to both sides of the rear part of the inner bottom surface, and also extends to the front of the center part. In this embodiment, the cold air guide passage 45 is formed by a recess.
吹出口43より吹き出され、流下して上収納箱体2の下
部に溜った冷気は効率よく、上帰還ダクト42に案内さ
れる。The cold air that is blown out from the air outlet 43, flows down, and accumulates in the lower part of the upper storage box body 2 is efficiently guided to the upper return duct 42.

しない。Dew that condenses and flows down the inner surface of the upper storage box 2 or water liquid spilled from the items stored in the upper storage box 2 accumulates on the bottom of the upper storage box 2 and flows from the cold air guide passage 45 to the upper return duct 42. It flows down from the lower return duct 28 to the dew pan 26. The water accumulated in the dew pan 26 is drained to the evaporation pan 32 through a drain pipe 33. The cold air flowing through the upper return duct 42 and the lower return duct 28 is cold air that has flowed inside the upper storage box body 2 and has a relatively high temperature, so the water does not freeze and the water flows in the same direction as the cold air. Because it flows, it flows smoothly and drains water. By using the upper and lower return ducts 42.28 as drainage passages, no special structure for drainage is required.

The mounting position of the shelves 51 is such that the distance between the shelves 51 can be changed depending on the usability of the user. Supports 53 are formed on both sides of the dorsal inner surface of the upper heat insulating box body 6 of the upper storage body 2. Pillar 5
3 is a hollow body made of metal. The shape of the hollow body may be a cylinder, a frame with a U-shaped cross section, or the like, as long as the inside thereof forms a cold air circulation duct. A plurality of locking holes 54 which also serve as ventilation holes are formed in the vertical direction in the support column 53. The locking hole 54 is formed, for example, in a vertically elongated rectangular shape, and is formed in the front wall of the support column 53. Although an engaging body that is directly locked to the locking hole 54 of the support column 53 may be formed at the rear end of the shelf 51, in this embodiment, the separate shelf support supports the body 55 to the support column 5.
3 and indirectly connect the shelf 51 to the support post 5.
It is supported by 3. The shelf 51 has both side parts and the shelf support is the body 55.
The shelf 51 is placed and supported, and both side edges of the shelf 51 are opposed to the positioning pieces 56 to prevent the shelf 51 from rubbing sideways. The positional relationship between the shelf 51, the shelf support body 55, and the positioning piece 56 is clearly shown in FIGS. 11 and 12.

造が簡略となる。The lower end of the support column 53 is open and communicates with the cold air guide passage 45 with which the main return duct 42 communicates. By communicating the pillar 53 with the cold air guide passage, the cold air flows through the pillar 53.
The cold air is sucked in through the locking hole 54 and flows downward inside the support column 53 and into the cold air guide passage 45. Since the cold air is sucked in through the locking hole 54 of the support column 53, the pressure in the space between the shelves 51, 52 is reduced, and the cold air blown out from the outlet 43 is sucked into the space between the shelves 51, 52. Therefore, the shelf 51,
.. In this implementation structure where 52 has no air permeability, the air outlet 43
This prevents the cold air blown out from flowing down along the door body 4 and directly from the cold air guide passage 45 into the main return duct 42, allowing the cold air to circulate efficiently within the upper storage body 2. . By using the support column 53 as a cold air suction duct, there is no need to form a separate duct, and the structure is simplified.

く、枢支側部分を挿入することができる。When the door body 4 is in the closed state, its pivot side portion is in the position shown in FIG. 11. In this state, when the movable side of the door body 4 is pulled forward to open, a force that tries to rotate around the support shaft 88 is first applied, and the support shaft 87 is moved along the first guide portion 85. This results in a force acting to move it inward. When a force trying to move the support shaft 87 along the first guide section 85 acts, a force that tries to move the support shaft 88 along the second guide section 86 acts in turn. The force acting on the support shafts 87 and 85 to open the door body 4 causes the support shafts 87 to move inward along the first guide portion 85, and the support shafts 88 to move toward the second guide portion. This acts as a force to move the door body 4 outward along the section 86, and guides the door body 4 to open it. By this operation, the pivot side of the door body 4 is pushed into position along the side inner surface of the upper storage box body 2 in the open state as shown in FIG. By inserting the pivot side of the door body 4 into the upper storage box body 2, the amount of protrusion of the door body 4 in the open state is reduced. Since the door body 4 is opened while being inserted into the upper storage box body 2 even during opening, the space of the door body 4 for opening can be reduced. The opening/closing operation of the door body 4 can be performed in the same manner as the opening/closing operation of a door body pivoted at one point, and the pivot side portion can be inserted without requiring a pushing operation of the door body 4.
