JP-A-2001-204428

In the container described in Patent Document 1, since the electrodes are arranged in an exposed state in the internal space of the container, for example, an unintended current flows from the electrode to the inner wall surface of the container through foreign matter adhering to the outer surface of the electrode. so-called leakage current may occur. Foreign matter adhering to the outer surface of the electrode includes water components present in the inner space of the container, frost formed inside the container, dust adhering to the outer surface of the electrode over time, and the like. When leakage current occurs, the current value of the voltage applying device increases, which may cause problems such as an increase in power consumption.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a container capable of forming a more uniform electric field while suppressing leakage current.

A container for solving the above-mentioned problems is composed of a container body having a container inside, an electrode member arranged in the container, and an electrode member separate from the electrode member. and an intermediate member disposed in the . The electrode member has an electrode body that forms an electric field inside the storage chamber based on voltage application, and an insulating member that surrounds the electrode body, and is fixed to the intermediate member. The intermediate member is made of an insulating material.

If the periphery of the electrode body is surrounded by the insulating member as in this configuration, foreign matter is less likely to come into direct contact with the outer surface of the electrode body. Therefore, it is possible to suppress the occurrence of leakage current in the electrode main body through foreign matter. Further, since the intermediate member is arranged between the inner surface of the container body and the electrode member, the electrode member can be separated from the inner surface of the container body. As a result, it becomes difficult to form an electric field from the electrode member that is directed directly toward the inner surface of the container body rather than toward the inside of the container body. Moreover, since the intermediate member is made of an insulating material, this configuration also makes it difficult to form an electric field that is directed directly from the electrode member to the inner surface of the container body. Therefore, it becomes possible to form a more uniform electric field inside the container body.

In the container described above, it is preferable that the electrode main body and the insulating member are integrally molded.
With this configuration, the electrode main body can be reinforced by the insulating member, so that the electrode main body can be made as thin as possible. Therefore, it becomes possible to reduce the weight of the electrode member.

Said storage shed WHEREIN: It is preferable that the insulating member is formed with resin.
With this configuration, it is possible to easily integrate the electrode main body and the insulating member.
Another container for solving the above problems is composed of a container main body having a container inside, an electrode member arranged in the container, and an electrode member separate from the electrode member, and the inner surface of the container main body and the electrode member and an intermediate member disposed between. The electrode member has an electrode body that forms an electric field inside the storage chamber based on voltage application, and a first insulating member and a second insulating member that sandwich the electrode body in the thickness direction, and is fixed to the intermediate member. ing. The intermediate member is made of an insulating material.

If the electrode main body is sandwiched between the first insulating member and the second insulating member as in this configuration, most of the outer surface of the electrode main body can be covered with the first insulating member and the second insulating member. Therefore, it is difficult for foreign matter to come into direct contact with the outer surface of the electrode main body, so that it is possible to suppress the occurrence of leakage current in the electrode main body through the foreign matter. Further, since the intermediate member is arranged between the inner surface of the container body and the electrode member, the electrode member can be separated from the inner surface of the container body. As a result, it becomes difficult to form an electric field from the electrode member that is directed directly toward the inner surface of the container body rather than toward the inside of the container body. Moreover, since the intermediate member is made of an insulating material, this configuration also makes it difficult to form an electric field that is directed directly from the electrode member to the inner surface of the container body. Therefore, it becomes possible to form a more uniform electric field inside the container body.

Preferably, in the container described above, the intermediate member is formed in a rectangular shape, and the electrode member is fixed to the bottom surface of the intermediate member.
In the container described above, the intermediate member has a hat-shaped cross section having a flat bottom and a pair of legs continuously formed from the bottom, and the electrode member is fixed to the bottom of the intermediate portion. preferably.

It is preferable that the above storage includes a transformer that applies voltage to the electrodes and a control panel that controls the transformer, and the total weight of the transformer is less than 36 [kg].
It is preferable that the storage container is a new or second-hand product.

According to the container of the present invention, it is possible to form a more uniform electric field while suppressing leakage current.

A container 10 shown in FIG. 1 is used as a refrigerator for refrigerating articles to be stored therein. The articles stored in the container 10 are fresh foods, dairy products, noodles, and the like. Fresh foods include, for example, seafood such as fish and shellfish, fruits such as strawberries and apples, vegetables such as cabbage and tomatoes, meat such as beef and pork, eggs, and processed foods thereof. Dairy products include milk and cheese. Noodles are made from grain powder such as wheat flour and buckwheat flour. It should be noted that the articles stored in the storage shed 10 are not limited to foods, but may be fresh flowers, medicines, internal organs, and the like.

The container 10 can be used as a stationary refrigerator, a mobile refrigerator, or the like. A fixed refrigerator is a refrigerator installed indoors such as a food processing factory or a storage room. A mobile refrigerator is a refrigerator that is loaded onto a mobile object such as a ship or an airplane. Storage warehouse 10 may also be a container for transportation or other purposes, or an immovable warehouse such as a prefabricated warehouse. Furthermore, the storage shed 10 may be either new or second-hand.

As shown in FIG. 1, the container 10 includes a container body 20 in which articles can be stored, and a cooling device 30 built in the container body 20. As shown in FIG. In FIG. 1, the vertical direction upward is indicated by an arrow Z1, and the vertical direction downward is indicated by an arrow Z2.
The container main body 20 has a box body 40 and a pair of door portions 50 . The box 40 and the door portion 50 are made of a metal material such as aluminum or stainless steel, and are electrically grounded.

The box 40 is formed in a rectangular box shape having an opening in the front. A front opening of the box 40 is closed by a pair of doors 50 . A space surrounded by the inner surface of the box 40 and the inner surface of the door portion 50 forms a storage chamber S10, which is the internal space of the storage body 20 shown in FIG. Hereinafter, of the plurality of walls constituting the outer wall of the box 40 shown in FIG. The wall portion 42 arranged on the right side is sometimes called the "right side wall portion 42", and the wall portion 43 arranged on the left side when viewed from the door portion 50 is called the "left side wall portion 43". The wall portion 44 arranged at the bottom wall portion 44 is referred to as a "bottom wall portion 44". The accommodation room S10 is a space in which articles are accommodated. In order to improve the refrigerating performance of the container 10, a heat insulating material for suppressing heat transfer from the container S10 to the outside of the container 10 is embedded inside each of the box 40 and the door portion 50. .

As shown in FIG. 1, the pair of door portions 50 are connected to the box 40 so as to be openable and closable. In the container 10, by opening the door portion 50, it is possible to put any article into the accommodation room S10 or take out the article stored in the accommodation room S10 to the outside. Further, by closing the door portion 50, the accommodation room S10 becomes a closed space, and the articles inside the accommodation room S10 are stored in a cooling environment.

The cooling device 30 supplies cool air to the accommodation room S10 by being driven based on the supply of electric power, thereby cooling the inside of the accommodation room S10.
As shown in FIG. 2 , the container 10 further includes an intermediate member 60 and an electrode member 70 arranged near the inner surface of the upper wall portion 41 of the container body 20 .

The intermediate member 60 is formed in a rectangular shape from an insulating material such as resin. The intermediate member 60 is separate from the electrode member 70 . Mounting members 80 and 81 are fixedly provided on the upper portion of the right side wall portion 42 and the upper portion of the left side wall portion 43 of the container body 20, respectively. The mounting members 80 and 81 are made of an insulating material such as resin and formed in a substantially L shape. Note that the mounting members 80 and 81 may be made of a non-insulating material such as metal. Both ends of the intermediate member 60 are placed on the mounting members 80 and 81, respectively, so that the intermediate member 60 is installed above the storage chamber S10. An electrode member 70 is fixedly provided on the bottom surface of the intermediate member 60 . The intermediate member 60 is arranged between the inner surface of the upper wall portion 41 of the container body 20 and the electrode member 70 .

As shown in FIGS. 3 and 4, the electrode member 70 is shaped like a rectangular plate. 3 and 4, etc., the longitudinal direction of the electrode member 70 is indicated by an arrow X, and the lateral direction thereof is indicated by an arrow Y. As shown in FIG. The electrode member 70 has an electrode body 71 , an insulating member 72 and wiring 75 .
The electrode main body 71 is formed in a thin plate shape from a metal material such as steel. The electrode body 71 is surrounded by an insulating member 72 . The entire outer surface of the electrode body 71 is covered with an insulating member 72 except for the portion where the wiring 75 is connected.

The insulating member 72 is formed in a plate shape from an insulating material such as resin. As shown in FIG. 3, the insulating member 72 is formed with a plurality of insertion holes 720 along the outer edge and central portion thereof, which penetrate in the thickness direction. The electrode member 70 is fixedly attached to the intermediate member 60 shown in FIG.

As shown in FIGS. 3 and 4, the wiring 75 is formed so as to extend from one end of the electrode body 71 through the insulating member 72 and be exposed to the outside. The wiring 75 is for applying voltage to the electrode body 71 .
When the electrode member 70 is manufactured, the electrode body 71 and the insulating member 72 are integrally molded. For example, when a mold having a cavity corresponding to the electrode member 70 is used, the electrode body 71 to which the wiring 75 is connected is placed inside the mold, and then molten resin is poured into the mold. Subsequently, after the mold is cooled, the mold is removed from the resin-molded product, thereby manufacturing the electrode member 70 integrally molded so that the insulating member 72 made of resin surrounds the electrode main body 71 .

As shown in FIG. 3 , the wiring 75 is connected to a voltage application device 90 provided inside or outside the container body 20 . The voltage application device 90 includes a transformer 91 , a control panel 92 , and the like, and applies a predetermined high voltage to the electrode body 71 via wiring 75 . The transformer 91 boosts the voltage supplied from the power supply and applies it to the electrode body 71 . The control panel 92 has various circuits and the like for controlling the transformer 91 . The high voltage applied from the voltage application device 90 to the electrode main body 71 may be, for example, an alternating voltage whose magnitude and direction change periodically with the passage of time, or may be an alternating voltage whose magnitude and direction change with the passage of time. may be a constant voltage that does not change. The electrode main body 71 forms an electric field in the storage chamber S10 based on the high voltage applied by the voltage application device 90 .

Next, the action and effect of the storage shed 10 of this embodiment will be described. In addition, below, the article accommodated in accommodation room S10 is also called a content.
By forming an electric field in the storage room S10, it is possible to sterilize the contents in the storage room S10 and to accelerate the ripening of the contents. Therefore, the contents can be stored for a long period of time while maintaining freshness, and the taste of the contents can be amplified. In addition, since the freezing point of the content can be lowered by the presence of the content in an environment with a predetermined electric field, the content does not freeze even in a lower temperature environment, for example, a negative temperature environment. can be saved. Therefore, it is possible to maintain the freshness of the contents for a longer period of time.

In addition, since the electrode main body 71 is surrounded by the insulating member 72 in the container 10 of the present embodiment, it is difficult for foreign matter to directly contact the outer surface of the electrode main body 71 . Therefore, it is possible to suppress the occurrence of leakage current in the electrode main body 71 through foreign matter.
FIG. 5A is a chart obtained by experimentally measuring the leakage current when using the electrode member of the comparative example and the leakage current when using the electrode member 70 of the present embodiment. . The electrode member of the comparative example has a structure in which the electrode main body is exposed, in other words, a structure in which the electrode main body is not surrounded by an insulating member. The surface area of the electrode member of the comparative example is set to "16.32 [m ² ]". On the other hand, the surface area of the electrode member 70 of this embodiment is set to "14.48 [m ² ]". In this experiment, a leakage current of "18 [mA]" was measured when the electrode member of the comparative example was used, and a leakage current of "8 [mA]" was measured when the electrode member 70 of the embodiment was used. rice field. Therefore, as compared with the electrode member of the comparative example, the electrode member 70 of the present embodiment can reduce the leakage current by about 41[%]. Incidentally, the current value per unit surface area is also smaller in the electrode member 70 of the present embodiment than in the electrode member of the comparative example.

FIG. 5B is a chart obtained by experimentally measuring the leakage current when the surface areas of the electrode member of the comparative example and the electrode member 70 of the present embodiment are set to the same value. The surface areas of the electrode member of the comparative example and the electrode member 70 of the comparative example were both set to "500 [mm] x 400 [mm]. In this experiment, when the electrode member of the comparative example was used, [0 A leak current of 0.15 [mA]] was detected, and a leak current of "0.09 [mA]" was detected when the electrode member 70 of the present embodiment was used. This experiment also confirmed that the electrode member 70 of the present embodiment can reduce the leakage current by about 40[%] as compared with the electrode member of the comparative example. By reducing the leakage current in this way, the current value to be supplied to the electrode member 70 can be reduced, and as a result, a smaller transformer 91 can be used. Therefore, it is possible to make the overall weight of the container 10 lighter than that of the conventional container.

In addition, as shown in FIG. 2, the intermediate member 60 is arranged between the inner surface of the upper wall portion 41 of the container main body 20 and the electrode member 70, so that the inner surface of the upper wall portion 41 of the container main body 20 does not move. , the electrode member 70 can be spaced apart. As a result, it becomes difficult to form an electric field that directly goes from the electrode member 70 to the inner surface of the upper wall portion 41 of the storage main body 20 without going to the inside of the storage main body 20 . Moreover, since the intermediate member 60 is made of an insulating material, even with this configuration, it is difficult to form an electric field that directly goes from the electrode member 70 to the inner surface of the upper wall portion 41 of the container body 20 . Therefore, it becomes possible to form a more uniform electric field inside the container main body 20 . Furthermore, if the intermediate member 60 is arranged between the inner surface of the upper wall portion 41 of the container body 20 and the electrode member 70 as in this embodiment, the upper wall portion 41 of the container body 20 Compared to a configuration in which a space is simply formed between the inner surface and the electrode member 70, it is possible to increase the structural strength.

On the other hand, in the container 10 of this embodiment, the electrode main body 71 and the insulating member 72 are integrally molded. According to this configuration, the electrode main body 71 can be reinforced by the insulating member 72, so that the electrode main body 71 can be made as thin as possible. Therefore, the weight of the electrode member 70 can be reduced.

FIG. 6 is a chart obtained by experimentally measuring the weight of the electrode member of the container of the comparative example and the weight of the electrode member 70 of the container 10 of the present embodiment. Since the housing of the comparative example has a structure in which the electrode main body is not surrounded by an insulating member, the electrode main body requires a required rigidity. Therefore, the weight of the electrode body tends to increase. In this respect, in the container 10 of the present embodiment, the electrode main body 71 can be reinforced by the insulating member 72. Therefore, as shown in FIG. It is possible to reduce the weight of the member by about 400 [kg]. Due to the weight reduction of the electrode member, the loading weight of the container 10 of the present embodiment can be increased compared to the container of the comparative example.

In addition, as described above, the electrode member 70 of the present embodiment can reduce leakage current, so that the weight of the voltage application device 90 can be reduced. Specifically, as shown in FIG. 6, in the container 10 of the present embodiment, the weight of the voltage application device can be reduced by about "80 [kg]" as compared with the container of the comparative example. be. As a result, when viewed as a whole container, the weight of the container 10 of the present embodiment can be reduced by about "480 [kg]" as compared with the container of the comparative example.

On the other hand, in the conventional container, it is necessary to form an electric field with a higher intensity in order to obtain a higher effect of ensuring the freshness of perishable food. That is, it is necessary to apply a higher voltage to the electrodes. In order to meet such requirements, the voltage pattern applied to the electrodes from the voltage application device includes not only a voltage pattern corresponding to a low voltage, but also a plurality of patterns such as a voltage pattern corresponding to a high voltage. It is In order to realize a plurality of voltage patterns, transformer capacities corresponding to them are required. As a result, conventional containment vaults must be equipped with multiple transformers. This increases the weight of the voltage application device, which in turn increases the weight of the entire container.

On the other hand, in the container 10 of the present embodiment, as described above, it is possible to form a more uniform electric field in the container 10. Therefore, even if the number of voltage patterns is reduced, a sufficient electric field likely to gain strength. If the number of voltage patterns can be reduced, the capacity of the transformer can be reduced. That is, the number of transformers 91 can be reduced. Therefore, in the container 10 of this embodiment, it is possible to reduce the total weight and total volume of the transformer 91 as compared with the conventional container.

Specifically, in the conventional warehouse, as the voltage pattern applied to the electrodes from the voltage application device, for example, a voltage pattern set for each 1 [kV] in the range of 2 [kV] to 7 [kV] is used. A total of six voltage patterns are used. In order to realize these six voltage patterns, six transformers are required in the voltage application device. Therefore, if the weight of one transformer is "6 [kg]", the total weight of the transformers is "36 [kg] (=6 [kg]×6)". On the other hand, in the storage warehouse 10 of the present embodiment, the number of transformers 91 can be reduced to less than six, so the total weight of the transformers can be less than "36 [kg]". .

Similarly, if the volume per transformer is "0.00594 [m ³ ]", the total volume of the transformers in the conventional storage is "0.03564 [m ³ ] (=0.00594 [m ³ ]×6)”. On the other hand, in the container 10 of the present embodiment, the number of transformers 91 can be reduced to less than six, so the total volume of the transformers 91 should be less than "0.03564 [m ³ ]". is possible.

Moreover, in the container 10 of the present embodiment, the insulating member 72 of the electrode member 70 is made of resin. According to this configuration, the electrode main body 71 and the insulating member 72 can be easily integrated by using the manufacturing method described above.

One outer surface 710 of the electrode main body 71 in the plate thickness direction is entirely covered with a first insulating member 73 . The other outer surface 711 of the electrode main body 71 in the plate thickness direction is entirely covered with a second insulating member 74 . Each insulating member 73, 74 is fixed to the electrode main body 71 by adhesion or the like.

If the electrode main body 71 is sandwiched between the first insulating member 73 and the second insulating member 74 in the thickness direction as in this configuration, most of the outer surface of the electrode main body 71 is covered by the first insulating member 73 and the second insulating member 74 . can be covered by Therefore, it becomes difficult for foreign matter to come into direct contact with the outer surface of the electrode main body 71 , so that generation of leakage current in the electrode main body 71 via the foreign matter can be suppressed.
