And a room panel 10.

The heat-insulating door 7 is provided with a handle 7A and a keyhole 7B for locking the heat-insulating door 7.

A slit-shaped suction port 11 is formed in the machine room panel 10, and a control panel 12 is exposed. In addition, 13 is a pedestal with an adjuster that supports the low-temperature storage 1, 14 is a caster that can move the low-temperature storage 1, 15 is a storage product such as a brown rice bag to form a gap with the bottom wall of the heat insulating box 6. A snowboard on which 16 and the like are placed.

Furthermore, the left and right side walls 1 in the heat insulating box 6
A plurality of air ribs 20 extending in the up-down direction are provided on the side walls 19 on the rear sides 7 and 18. This air rib 2
No. 0 is provided so as to be located at the center of the brown rice bag 16 when the brown rice bag 16 is stored. Therefore, a gap is formed between the brown rice bag 16 and each of the side walls 17, 18, 19, and the brown rice bag 16 can be cooled uniformly.

In this embodiment, a brown rice bag 16 capable of storing 30 kg of brown rice is used. This bag is made of cardboard and is 620 mm long, 400 mm wide and 170 mm high.
Is the size of The size of the brown rice bag 16 varies depending on the weight of the brown rice, but a fixed bag is used.

When the standard brown rice bag 16 is stored such that the length direction is horizontal and the width direction is depth,
Two rows can be placed on the left and right.

Therefore, as shown in FIG. 3, the air ribs 20 are provided in two rows on the left and right side walls 17 and 18 and are provided on the rear side wall 19 in two rows.
A row is provided.

Further, as shown in FIG. 2, cold air flows between the brown rice bags 16, 16 placed on the left and right sides, so that
The air rib 20A may be provided substantially at the center of the air rib. In the air rib 20A at the center of the side wall 19,
A drain hose 21 for draining drain water from the cooling device 8 is provided.

The material of the air rib 20 (the air rib 20A has the same structure) is a soft vinyl chloride resin, which is manufactured by extrusion molding and has a cylindrical shape.
That is, a space 23 that communicates vertically is formed inside.

With the above configuration, the cooling device 8 of the present invention will be described with reference to FIGS.

In the cooling device 8, in addition to the evaporator 22,
A blower 24 for circulating cool air is provided in the refrigerator,
The drain hose 21 is connected, and is covered with a cover 25 which also serves as a drain pan and a fan casing.

The blower 24 is of a suction type and comprises a cooling fan 24A and a fan motor 24B for driving the cooling fan 24A to rotate. The fan motor 24B is connected to the cover 25 by a motor fixing bracket 26. It is fixed to.

As shown in FIG. 3, the air ribs 20 are opposed to the rear air ribs 20 attached to the left and right side walls 17 and 18.

With such a configuration, as shown by the arrows in FIG.
Since the cool air is diverted in the left and right direction, and the left and right outlets 28 and 29 are opposed to the air rib 20, the air rib 2
At 0, the flow is diverted in the front-rear direction.

Further, the brown rice bag 16 is formed by the air rib 20.
As shown by solid arrows in FIG. 2, the cool air flows downward through the gap between the brown rice bag 16 and the left and right side walls 17 and 18, and It is guided downward, moves upward from the central part, and is introduced into the cooling device 8 from the suction port 27.

Further, as described above, since the space 23 communicating vertically is formed in the air rib 20, the air rib 20 flows downward in the space 23 of the air rib 20 as shown by a dotted arrow in FIG. After passing below, it moves upward from the central portion and is introduced into the cooling device 8 from the suction port 27.

As described above, the cool air is applied to the brown rice bag 1 located above.
Cooling can be uniformly performed from 6 to the brown rice bag 16 located below, so that cooling unevenness in the refrigerator can be prevented as much as possible.

Further, the stored items 16 of the low-temperature storage 1 of the present invention may be not only brown rice but also other foods such as vegetables, meat, fish and beer. When used in a minus temperature zone, the drain hose 21 needs to be provided with a heating device such as an electric temperature heater.
