[0004]

Therefore, it is conceivable to store polished rice at a low temperature by using a refrigerator, for example, using a refrigerator. They are often not suitable for storage. Even if the milled white rice is stored in small bags, it must be taken out and stored each time rice is cooked, which requires extremely complicated labor.

On the other hand, the above-mentioned conventional grain storage is originally for business use, and therefore has a large storage capacity, requires a large amount of energy, is often provided with a separate cooling unit, and occupies a large area. There is a problem that it is large. In order to maintain a low-temperature atmosphere, the storage section must be thermally isolated from the outside air by heat insulating material, but most of the grain outlets or outlets are not provided with heat insulating material. There is a problem that power loss is large due to insufficient power. In addition, it is conceivable to surround the whole storage including the grain outlet with a heat insulating material, but it is not preferable because the volume of the cooling space required becomes large and more energy is required.

There is also a type in which a Peltier element is provided in a part of an outer shell constituting a storage unit and is rapidly cooled by a cooling fan. In addition, there is a problem that the temperature distribution in the entire storage section becomes non-uniform and the cooling rate is low.

An object of the present invention is to solve the above-mentioned problems in the prior art, and to provide a grain storage which can maintain grain quality, is small in size and consumes low power, and can store grains uniformly at a low temperature. And

Reference numeral 3 denotes a lid member, which is made of a heat insulating material and is detachably provided in an opening above the housing 1. By providing, for example, a rubber magnet on the contact surface of the lid member 3 with the housing 1, the degree of adhesion between the two can be improved.

Reference numeral 4 denotes a storage section, which is provided inside the housing 1 and is formed so that, for example, white rice 5 can be charged and stored through an opening above the storage section. The lower part of the storage part 4 is formed in a funnel shape, and the lower end part thereof is provided with a discharge port 6 penetrating the housing 1. Reference numeral 7 denotes a fan, which is provided above the storage unit 4. Reference numerals 8 and 9 denote small windows made of a transparent material, which are provided on the side of the storage unit 4 and the housing 1, respectively, for checking the remaining amount of the white rice 5 in the storage unit 4 from outside. .

Reference numeral 10 denotes a shutter, which is provided to be movable in the horizontal direction so as to face the discharge port 6. The shutter 10
Is formed at least in the vicinity of the outlet 6 using a heat insulating material as a constituent member. Reference numeral 11 denotes a measuring unit, and the shutter 10
Is provided in the vicinity of the front end of the shutter 10 so as to penetrate the shutter 10, and its projected shape dimension on a plane is formed corresponding to the discharge port 6. Reference numeral 12 denotes a stopper, which is provided at a lower portion of the housing 1 and regulates a moving range of the shutter 10. Reference numeral 13 denotes an extraction, which is formed in a box shape and is provided below the shutter 10 so as to be movable in the horizontal direction, so that white rice from the weighing unit 11 of the shutter 10 can be stored via a guide 14.

Next, 15 and 16 are a compressor and a condenser, respectively, which are provided in the support 2. Reference numeral 17 denotes an evaporator, which is provided in a gap between the side surface of the storage unit 4 and the side surface of the housing 1 so as to surround the storage unit 4, for example. And compressor 1
