2. Description of the Related Art Conventionally, a small refrigerator has been used as a low-temperature storage for storing various foods used at home.
In this refrigerator, the inside is partitioned into small rooms, and for example, rice and vegetables cannot be stored in large quantities for a long period of time due to internal volume limitations.

[0003] In recent years, as interest in the quality of rice has increased, a large number of low-temperature storages of various volumes have been developed to store a large amount of cereals such as white rice and brown rice at a low temperature in each bag to prevent deterioration in cereal quality. Widely used by farmers.

[0004] When a relatively large low-temperature storage having a capacity of, for example, 1800 liters is used, if the cereals stored in the storage are used every day, the storage amount is reduced to about half near summer. At present, other storage items such as vegetables, fruits, flowers, and the like (hereinafter, collectively referred to as vegetables) are stored in an open space in the storage.

[0005]

However, in this low-temperature storage, since storage conditions such as temperature and humidity in the storage are set for grains mainly made of brown rice,
When vegetables are stored, the quality deteriorates, such as drying of the vegetables, and the vegetables cannot be stored for a long time. As a result, the items to be stored in the cold storage are specified,
There is a problem in that the usability is inferior and the open space in the storage increases, so that the space in the storage cannot be effectively used.

The present invention has been made in view of such circumstances, and an object of the present invention is to store cereals and vegetables in a storage for a long period of time, to improve the usability thereof, and to improve the space in the storage. Another object of the present invention is to provide a low-temperature storage that can effectively utilize the storage.

[0007]

In order to achieve the above object, the invention according to claim 1 of the present invention has a storage inside a casing having an internal volume of about 1800 liters, and a front opening of the casing. In a low-temperature storage in which a storage device is stored in a low-temperature state in which a storage device is provided in a storage and a cooling device is provided at an upper portion, at least two storages are provided in the storage, and each storage has an opening and closing door. And at least one of the at least two storages.
A storage is formed in a forced circulation structure by the cooling device,
Can be set to 60-70% humidity and cereals are stored
In both cases, the other storage is a surface cooling structure by the cooling device.
It is formed and its humidity can be set to 90% or more,
It is characterized by being stored .

[0008]

By forming in this way, cereals
For example, vegetables are stored in one storage of a forced circulation structure of low temperature and low humidity with a humidity of 60 to 70%, and vegetables have a humidity of, for example, 9%.
It is stored in the other low temperature and high humidity storage having a surface cooling structure of 0% or more. Cereals and vegetables are stored under the most suitable conditions, preventing the deterioration of the grains and drying of the vegetables,
Stored for a long time without reducing its quality. As a result, the application range of the storage object is expanded, the usability of the low-temperature storage is greatly improved, and the open space in the storage can be reduced, so that the space can be effectively used.

The invention according to claim 2 is characterized in that the storage conditions of at least two storages can be individually controlled, and the invention according to claim 3 is characterized in that at least two storages are stored. It is characterized in that the storage conditions can be controlled to be the same conditions.

[0011] By forming as described above, each storage is individually controlled and the storage conditions in the storage are set respectively. Therefore, for example, one storage has optimal storage conditions according to the characteristics of the cereal, and The other storages are stored under optimum conditions according to the characteristics of vegetables and the like without being affected by each other.

By setting the storage conditions of both storages to be the same, for example, both storages are set to low temperature and low humidity to store only grains, or both storages are set to low temperature and high humidity to store only vegetables and the like. Can be stored, the usability of the low-temperature storage can be further improved, and the space in the storage can be more effectively utilized.

It is connected to a provided temperature sensor (not shown). The temperature indicators 33 and 34, the temperature sensors, and the operation switches 27 and 29 of the operation panel 25 are appropriately connected to the cooling device 16, and by operating the operation panel 25, the low humidity chamber 10 and the high humidity chamber 10 are operated. The storage conditions such as the temperature in 11 are set, and the low-temperature storage 1 is operated.

The temperature controllers 28, 30 of the operation panel 25
The adjustment range is set to about 5 ° C. to 15 ° C. A caster 35 with four stoppers for movement is provided on the bottom surface 2e of the housing 2, and a power cord 36 (see FIG. 2) is drawn out on the back side of the cooling device 16.

Here, the method of using the low-temperature storage 1 is as follows.
Description will be made based on the usage pattern diagram of FIG. First, the opening and closing door 4 is opened, and brown rice bags F containing brown rice as grains are stored in the low-humidity storage 10 in a state where the bags F (for example, seven bags) are stacked. At this time, a rice pad 12 is set on the floor 10a of the low humidity chamber 10, and a brown rice bag F is placed on the rice pad 12. Further, the opening / closing door 5 is opened to store appropriate vegetables (potatoes Y1 in a bag, pumpkin Y2, etc.) in the high humidity chamber 11. In addition, the storage of vegetables is not carried out, but it can also be used as needed.

Then, the doors 4 and 5 are both closed, and the power cord 36 is plugged into, for example, a household 10 V power outlet (not shown).
6 is turned on, the operation switches 27 and 29 are turned on, and the temperatures of the low humidity chamber 10 and the high humidity chamber 11 are set by the temperature controllers 28 and 30, respectively. Since the set temperature is preferably about 12 ° C. for brown rice, the set temperature of the temperature controller 28 is set to 12 ° C.
The temperature controller 30 is appropriately (for example, 5
° C).

When the operation switch 27 of the low humidity chamber 10 is turned on, the evaporator fan 18 turns on and off in synchronization with the operation of the compressor 17 of the cooling device 16. 6, a flow of air (cold air) is generated to cool the brown rice bag F (brown rice) as shown by arrows a and b in FIG.
Is stopped, and the steam adhering to the evaporator fins (not shown) falls under its own weight to dehumidify the low humidity chamber 10.

After a predetermined time, the humidity in the low-humidity storage 10 is in an equilibrium state at about 60 to 70%, and the water content of the brown rice in the brown rice bag F at this time becomes about 14%. This allows
The deterioration of quality such as deterioration due to excessive moisture content of brown rice is prevented.

On the other hand, in the high humidity chamber 11, the cool air is not directly blown out from the cooling device 16, and the cool air flows through the cool air passage 13 a of the inner box 13 as shown by an arrow C, and the entire inner surface of the inner box 13 is Is surface cooled. Therefore, since there is no air in and out of the high humidity chamber 11, the air in the high humidity chamber 11 does not dry, and the relative humidity in the high humidity chamber 11 decreases by an amount corresponding to lowering the temperature in the chamber, and usually 90%. The above humidity is secured.

Due to this high humidity, vegetables are stored in the high humidity chamber 11 without drying. If it is desired to further increase the water content in the high-humidity storage 11, it is possible to obtain a humidity condition close to 100% by adding water or wet newspaper (not shown) to vegetables. .

As described above, according to the low-temperature storage 1 of the above embodiment, the inside of the one-box type storage 8 is divided into two, and the low-temperature low-humidity low-humidity storage 10 and the low-temperature high-humidity high-humidity storage 11 are provided. For example, the brown rice bag F can be stored in the low humidity storage 10 and the vegetables can be stored in the high humidity storage 11, and the brown rice and the vegetables can be stored simultaneously in one low temperature storage 1.

As a result, unlike the prior art, there is no opening space in the storage 8 during the summer season,
Brown rice and vegetables can be stored efficiently inside,
The usability of the low-temperature storage 1 is greatly improved, and the space in the storage 8 can be effectively used.

In addition, brown rice can be stored in the low humidity storage 10 under storage conditions suitable for the characteristics of brown rice, and vegetables can be stored in the high humidity storage 11 under storage conditions suitable for the characteristics of vegetables. In addition, it is possible to reliably prevent quality deterioration of the stored material such as deterioration of brown rice and drying of vegetables.

In particular, the low-humidity storage 10 has brown rice at a temperature of 12 °.
The storage condition of the circulating cooling system at about C and the humidity of 60 to 70%, and the high humidity chamber 11 can store the vegetables under the storage condition of the surface cooling system at a temperature of about 5 ° C and a humidity of 90% or more. Therefore, brown rice and vegetables can be stored in a stable state for a long period of time. And in the high humidity chamber 11,
For example, by using wet newspaper or the like, storage can be performed at a humidity close to 100%, so that vegetables can be stored more stably for a long period of time.

Further, since the low humidity chamber 10 and the high humidity chamber 11 can be individually opened and closed by one separate opening / closing door 4, 5,
Only the necessary storage can be used alone, preventing leakage of cold air, etc., and enabling efficient storage of brown rice and vegetables, and suitable for the size of the low humidity storage 10 and the high humidity storage 11, for example. A large amount of brown rice and vegetables can be stored, and a more convenient low-temperature storage 1 can be obtained.

Further, since the low humidity chamber 10 and the high humidity chamber 11 can be operated independently by operating the operation switch 27 and the operation switch 29 of the operation panel 25, for example, when it is not necessary to store vegetables, If it is not necessary to turn off the operation switch 29 of the high humidity chamber 11 or to store brown rice, the operation switch 27 of the low humidity chamber 10 may be turned off, and the wasteful power associated with the idle operation may be reduced. Consumption can be prevented, and an energy saving effect can be obtained.

The temperature controllers 28 and 30 of the operation panel 25
, That is, the storage conditions of the low humidity chamber 10 and the high humidity chamber 11 can be set to be the same. For example, when there is no need to store vegetables, brown rice is stored in the high humidity chamber 11. Can be made and only vegetables can be stored in a low-humidity
0 and the high humidity chamber 11.

As a result, one low-temperature storage 1 can be stored in three ways: brown rice and vegetables, brown rice only and vegetables only, in three ways, and its versatility is greatly improved, making it easier to use. In addition to the improvement, for example, it is not necessary for a farmer or the like to have a low-temperature storage for brown rice and a low-temperature storage for vegetables, so that the economic burden on the user can be reduced.

Furthermore, since the casters 35 with stoppers are provided on the bottom surface 2e of the housing 2, the relatively large low-temperature storage 1 can be easily moved, and the storage container 12 is placed in the low-humidity storage 10. Is provided so that it can be detached, so that it is possible to select and use the cage 12 according to the type of the material to be stored.

In the above embodiment, the case where the inside of the storage 8 is divided into two parts has been described. However, the present invention is not limited to this. For example, as shown by a two-dot chain line in FIG. The inside of the warehouse 11 is divided into upper and lower parts by a partition plate 40,
Three storages may be provided in the storage 8.

With such a structure, different vegetables can be arranged and stored in the high-humidity storage 11 and the storage object other than the vegetables can be stored. In this case, it is of course possible to provide a plurality of storages in the low-humidity storage 10, and if the low-humidity storage 10 or the high-humidity storage 11 is divided into a plurality of parts, the opening / closing doors 4 and 5 may be divided as necessary. good.

In the above embodiment, the high humidity storage 11
Although the case where vegetables are stored as vegetables in the inside has been described, not only these vegetables but also vegetables such as fruits and flowers can be stored in the high humidity chamber 11. When these fruits and flowers are stored for a long period of time, ethylene gas, which is a plant aging hormone, is generated and the freshness of the fruits and the like is likely to be reduced. Therefore, an ethylene gas removing device (not shown) is installed. Better to do.

Further, in the above embodiment, the low humidity storage 1
0 and a temperature controller 28 for controlling the storage conditions of the high humidity chamber 11,
The adjustment range of 30 is set to be the same.
May be set to 2 to 15 ° C. and slightly different from the low humidity chamber 10. In this way, it is possible to easily set the stable storage temperature of vegetables and fruits at 3 to 5 ° C.
More stable storage of vegetables is possible.

Further, in the above embodiment, the case where the internal volume of the storage 8 is approximately 1800 liters, which is the most used range in general farms, has been described. For example, 150
Including a volume of about 0-2100 liters,
Further, in the above embodiment, the case of brown rice has been described as the cereal, but the cereal according to the present invention includes, for example, rice such as white rice and all cereals such as wheat, barley, beer wheat, and soybean.

Further, in the above embodiment, the low-temperature storage 1
It is needless to say that the overall shape, the structure and the arrangement position of the operation panel 25, the arrangement positions of the temperature indicators 33 and 34, and the like are merely examples, and various changes can be made without departing from the gist of each invention.
