[0005] PATENT LITERATURE

[0006] Patent Literature 1: Japanese Patent Application Laid-Open No. 2001-204428 SUMMARY

[0007] PROBLEMS TO BE SOLVED BY THE INVENTION

[0008] In the storage described in Patent Literature 1, since the electrode is arranged in the inside space of the storage in an exposed state, for example, it is possible that an undesirable current, so-called leakage current, flows from the electrode to the inner wall surface of the storage via a foreign matter attached to the outer surface of the electrode. The foreign matter attached to the outer surface of the electrode refers to a water component existing in the inside space of the storage, frost formed in the inside of the storage, dust attached to the outer surface of the electrode over time, and the like. If the leakage current occurs, the current value of the voltage application device increases, and thus it is possible that an adverse situation such as an increase in power consumption occurs.

[0009] The present application has been made in view of such a situation, and an object thereof is to provide a storage that can form a more uniform electric field while suppressing leakage current.

[0010] MEANS FOR SOLVING THE PROBLEM

[0011] The storage battery includes a storage battery main body having a storage chamber inside, an electrode member disposed in the storage chamber, and an intermediate member configured separately from the electrode member and disposed between an inner surface of the storage battery main body and the electrode member. The electrode member has an electrode main body that forms an electric field inside the storage chamber based on application of a voltage, and an insulating member that surrounds the electrode main body and fixes the electrode member to the intermediate member. The intermediate member is formed of an insulating material.

[0012] If the electrode main body is surrounded by the insulating member as in this configuration, it is difficult for foreign matter to directly contact the outer surface of the electrode main body. Therefore, it is possible to suppress generation of a leakage current in the electrode main body via the foreign matter. In addition, since the intermediate member is disposed between the inner surface of the storage battery main body and the electrode member, it is possible to separate the electrode member from the inner surface of the storage battery main body. Thus, it is difficult to form an electric field that directly faces the inner surface of the storage battery main body from the electrode member toward the inside of the storage battery main body. Moreover, since the intermediate member is formed of an insulating material, it is also difficult to form an electric field that directly faces the inner surface of the storage battery main body from the electrode member by this configuration. Therefore, it is possible to form a more uniform electric field inside the storage battery main body.

[0013] In the storage battery described above, it is preferable that the electrode main body and the insulating member be integrally formed.

[0014] According to this configuration, since it is possible to reinforce the electrode main body with the insulating member, it is possible to make the electrode main body as thin as possible. Therefore, it is possible to make the electrode member lightweight.

[0015] In the storage battery described above, it is preferable that the insulating member be formed of a resin.

[0016] According to this configuration, it is possible to easily integrate the electrode main body and the insulating member.

[0017] Another storage battery that solves the above-described problem includes a storage battery main body having a storage chamber inside, an electrode member disposed in the storage chamber, and an intermediate member configured separately from the electrode member and disposed between an inner surface of the storage battery main body and the electrode member. The electrode member has an electrode main body that forms an electric field inside the storage chamber based on application of a voltage, and a first insulating member and a second insulating member that sandwich the electrode main body in a thickness direction and fix the electrode member to the intermediate member. The intermediate member is formed of an insulating material.

[0018] If the electrode main body is sandwiched by the first and second insulating members as in this structure, most of the outer surface of the electrode main body can be covered by the first and second insulating members. Therefore, it is difficult for foreign matter to directly contact the outer surface of the electrode main body, and thus it is possible to suppress the generation of a leakage current in the electrode main body via the foreign matter. In addition, since the intermediate member is disposed between the inner surface of the storage main body and the electrode member, it is possible to separate the electrode member from the inner surface of the storage main body. Thus, it is difficult to form an electric field directly toward the inner surface of the storage main body from the inside of the electrode member toward the inner surface of the storage main body. Also, since the intermediate member is formed of an insulating material, it is also difficult to form an electric field directly toward the inner surface of the storage main body from the electrode member by this structure. Therefore, it is possible to form a more uniform electric field in the inside of the storage main body.

[0019] In the above-described storage, it is preferable that the intermediate member be formed in a rectangular shape, and the electrode member be fixed to the bottom surface of the intermediate member.

[0020] In the above-described storage, it is preferable that the intermediate member be formed in a hat shape having a flat bottom and a pair of leg portions continuously formed from the bottom, and the electrode member be fixed to the bottom of the intermediate member.

[0021] In the above-described storage, it is preferable that the storage include a transformer that applies a voltage to the electrode and a control panel that controls the transformer, and the total weight of the transformer be less than 36 [kg].

[0022] The above-described storage is preferably a new product or a second-hand product.

[0036] <First Embodiment>

[0037] Hereinafter, a first embodiment of a storage will be described with reference to the drawings. For easy understanding of the description, the same reference signs are attached to the same constituent elements in each drawing as much as possible, and repetitive description will be omitted.

[0038] Figure 1 The storage 10 shown in the drawing is used as a refrigerator that refrigerates and stores articles stored in the inside thereof. The articles stored in the storage 10 are fresh foods, dairy products, noodles, and the like. The fresh foods are, for example, seafood such as fish and shellfish; fruits such as strawberries and apples; vegetables such as Chinese cabbages and tomatoes; edible meat such as beef and pork; eggs; and processed foods thereof. The dairy products are, for example, milk or cheese. The noodles are made of a powder of a grain such as wheat flour or buckwheat flour. In addition, the articles stored in the storage 10 are not limited to foods, and can be, for example, flowers, pharmaceutical products, and organs.

[0039] Storage unit 10 can be used as a fixed refrigerator, a mobile refrigerator, etc. A fixed refrigerator is a refrigerator installed indoors in a food processing plant or storage facility. A mobile refrigerator is a refrigerator mounted on a mobile vehicle such as a ship or aircraft. Alternatively, storage unit 10 can also be a non-movable warehouse such as a shipping container (excluding those used for transport) or a prefabricated warehouse. Furthermore, storage unit 10 can be used for both new and used products.

[0040] like Figure 1 As shown, the storage compartment 10 includes a storage compartment body 20 capable of storing items inside and a cooling device 30 built into the storage compartment body 20. Additionally, in Figure 1 In the diagram, the vertical direction above is indicated by arrow Z1, and the vertical direction below is indicated by arrow Z2.

[0041] The main body 20 of the storage unit has a box 40 and a pair of doors 50. The box 40 and the doors 50 are made of metal materials such as aluminum and stainless steel, and are electrically grounded.

[0042] The box body 40 is formed into a rectangular box shape with an opening on the front. The opening on the front of the box body 40 is closed by a pair of doors 50. The space enclosed by the inner surface of the box body 40 and the inner surface of the doors 50 forms a... Figure 2 The interior space of the main storage unit 20 shown is the storage room S10. The following will describe the structure... Figure 2 Of the multiple wall portions on the outer wall of the shown housing 40, the wall portion 41 located at the top vertically Z1 is called the "upper wall portion 41," the wall portion 42 located on the right side when viewed from the door 50 is called the "right wall portion 42," the wall portion 43 located on the left side when viewed from the door 50 is called the "left wall portion 43," and the wall portion 44 located at the bottom vertically Z2 is called the "bottom wall portion 44." The storage chamber S10 is a space for storing items. To improve the refrigeration performance of the storage chamber 10, insulating material is embedded inside both the housing 40 and the door 50. This insulating material is used to suppress heat transfer from the storage chamber S10 to the outside of the storage chamber 10.

[0043] like Figure 1 As shown, a pair of doors 50 are connected to the housing 40 and can be opened and closed freely. In the storage compartment 10, by opening the doors 50, any item can be placed into the storage compartment S10 or the items stored in the storage compartment S10 can be taken out. In addition, by closing the doors 50, the storage compartment S10 becomes a closed space, and the items inside the storage compartment S10 are preserved in a cooling environment.

[0044] The cooling device 30 is driven by an electric power supply to supply cold air to the storage chamber S10 to cool the storage chamber S10.

[0045] like Figure 2As shown, the storage magazine 10 further has an intermediate member 60 and an electrode member 70 arranged near the inner surface of the upper wall portion 41 of the storage magazine main body 20.

[0046] The intermediate member 60 is formed in a rectangular shape by an insulating material such as resin. The intermediate member 60 is separate from the electrode member 70. A placement member 80, 81 is fixedly arranged at the upper portion of the right side wall portion 42 and the upper portion of the left side wall portion 43 of the storage magazine main body 20, respectively. The placement members 80, 81 are formed in a substantially L shape by an insulating material such as resin. Alternatively, the placement members 80, 81 can be formed by a material that does not have insulating properties, such as metal. By placing both end portions of the intermediate member 60 on the placement members 80, 81, respectively, the intermediate member 60 is arranged above the storage chamber S10. The electrode member 70 is fixedly arranged 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 storage magazine main body 20 and the electrode member 70.

[0047] As shown in Figs. 1 and 2, the electrode member 70 is formed in a rectangular plate shape. Alternatively, as shown in Figs. 3 and 4, the electrode member 70 can be formed in a rectangular plate shape with a cutout portion 710. Figure 3 Figure 4 As shown, the electrode member 70 is formed in a rectangular plate shape. Alternatively, as shown in Figs. 3 and 4, the electrode member 70 can be formed in a rectangular plate shape with a cutout portion 710. Figure 3 Figure 4 As shown in Figs. 1 and 2, the electrode member 70 is formed in a rectangular plate shape. Alternatively, as shown in Figs. 3 and 4, the electrode member 70 can be formed in a rectangular plate shape with a cutout portion 710.

[0048] The electrode main body 71 is formed in a thin plate shape by a metal material such as steel. The electrode main body 71 is surrounded by the insulating member 72. The outer surface of the electrode main body 71 is covered by the insulating member 72 except for a portion to which the wiring 75 is connected.

[0049] The insulating member 72 is formed in a plate shape by an insulating material such as resin. As shown in Figs. 1 and 2, a plurality of insertion holes 720 that penetrate in the thickness direction are formed in the outer edge portion and the central portion of the insulating member 72. The electrode member 70 is fixedly assembled to the intermediate member 60 shown in Fig. 1 by being screwed into the insertion holes 720. Figure 3 Figure 2 As shown in Figs. 1 and 2, the wiring 75 is formed so as to penetrate the insulating member 72 from one end portion of the electrode main body 71 and be exposed to the outside. The wiring 75 is used to apply a voltage to the electrode main body 71.

[0050] As shown in Figs. 1 and 2, the wiring 75 is formed so as to penetrate the insulating member 72 from one end portion of the electrode main body 71 and be exposed to the outside. The wiring 75 is used to apply a voltage to the electrode main body 71. Figure 3 Figure 4 As shown in Figs. 1 and 2, the wiring 75 is formed so as to penetrate the insulating member 72 from one end portion of the electrode main body 71 and be exposed to the outside. The wiring 75 is used to apply a voltage to the electrode main body 71.

[0051] ​​​​During the manufacture of the electrode component 70, the electrode body 71 and the insulating component 72 are integrally formed. For example, when using a mold having a cavity corresponding to the electrode component 70, after the electrode body 71 with the wiring 75 connected to it is placed inside the mold, molten resin is allowed to flow into the mold. Then, after the mold is cooled, if the mold is removed from the resin molded article, it is possible to manufacture an electrode component 70 in which the insulating component 72, made of resin, is integrally formed around the electrode body 71.

[0052] like Figure 3 As shown, wiring 75 connects to a voltage application device 90 located inside or outside the storage compartment body 20. The voltage application device 90 is configured to include a transformer 91 and a control panel 92, etc., and applies a predetermined high voltage to the electrode body 71 via wiring 75. The transformer 91 boosts the voltage supplied from the power source and applies it to the electrode body 71. The control panel 92 has various circuits for controlling the transformer 91, etc. The high voltage applied to the electrode body 71 from the voltage application device 90 can be, for example, an alternating voltage whose magnitude and orientation change periodically over time, or a constant voltage whose magnitude and orientation do not change over time. The electrode body 71 forms an electric field within the storage compartment S10 based on the high voltage applied by the voltage application device 90.

[0053] Next, the function and effects of the storage compartment 10 in this embodiment will be explained. Furthermore, from now on, the items stored in the storage room S10 will also be referred to as stored items.

[0054] By creating an electric field within the storage chamber S10, the stored items can be sterilized and their maturation promoted. Therefore, the stored items can be preserved for a long time while maintaining freshness, and their flavor can be enhanced. Furthermore, by placing the stored items in a controlled electric field environment, their freezing point can be lowered, allowing them to be preserved without freezing even at lower temperatures, such as sub-zero temperatures. This further maintains the freshness of the stored items for an extended period.

[0055] Furthermore, in the storage chamber 10 of this embodiment, since the electrode body 71 is surrounded by the insulating member 72, it is difficult for foreign objects to directly contact the outer surface of the electrode body 71. Therefore, leakage current generated in the electrode body 71 via foreign objects can be suppressed.

[0056] Figure 5(A) is a graph obtained by experimentally measuring the leakage current when using the electrode component of the comparative example and the leakage current when using the electrode component 70 of this embodiment. The electrode component of the comparative example has a structure in which the electrode body is exposed; in other words, it has a structure in which the electrode body is not surrounded by an insulating component. The surface area of ​​the electrode component of the comparative example is set to 16.32 [m²]. 2 In contrast, the surface area of ​​the electrode component 70 in this embodiment is set to 14.48 m². 2 In this experiment, a leakage current of 18 mA was measured when using the electrode component of the comparative example, and a leakage current of 8 mA was measured when using the electrode component 70 of the embodiment. Therefore, the leakage current can be reduced by approximately 41% in the electrode component 70 of this embodiment compared to the electrode component of the comparative example. Incidentally, the current value per unit surface area of ​​the electrode component 70 of this embodiment is also smaller than that of the electrode component of the comparative example.

[0057] Figure 5 (B) is a graph obtained by experimentally measuring the leakage current when the surface areas of the electrode components of the comparative example and the electrode component 70 of this embodiment are set to the same value. Furthermore, the surface areas of both the electrode components of the comparative example and the electrode component 70 of the comparative example are set to "500 [mm] × 400 [mm]". In this experiment, a leakage current of "0.15 [mA]" was detected when using the electrode component of the comparative example, and a leakage current of "0.09 [mA]" was detected when using the electrode component 70 of this embodiment. In this experiment, it was confirmed that the leakage current in the electrode component 70 of this embodiment can be reduced by approximately 40% compared to the electrode component of the comparative example. Thus, by reducing the leakage current, the current value that should be supplied to the electrode component 70 can be reduced, and therefore, a smaller transformer 91 can be used. Therefore, the overall weight of the storage container 10 can be made lighter than that of conventional storage containers.

[0058] In addition, such as Figure 2As shown, since an intermediate member 60 is disposed between the inner surface of the upper wall portion 41 of the storage container body 20 and the electrode member 70, the electrode member 70 can be separated from the inner surface of the upper wall portion 41 of the storage container body 20. Therefore, it is difficult to form an electric field from the electrode member 70 directly toward the inner surface of the upper wall portion 41 of the storage container body 20 without it facing the interior of the storage container body 20. Furthermore, since the intermediate member 60 is made of insulating material, it is also difficult to form an electric field from the electrode member 70 directly toward the inner surface of the upper wall portion 41 of the storage container body 20 with this structure. Therefore, a more uniform electric field can be formed inside the storage container body 20. Moreover, if the intermediate member 60 is disposed between the inner surface of the upper wall portion 41 of the storage container body 20 and the electrode member 70 as in this embodiment, the structural strength can be improved compared to a structure where only a space is formed between the inner surface of the upper wall portion 41 of the storage container body 20 and the electrode member 70.

[0059] On the other hand, in the storage compartment 10 of this embodiment, the electrode body 71 and the insulating member 72 are integrally formed. According to this structure, since the electrode body 71 can be reinforced by the insulating member 72, the electrode body 71 can be made as thin as possible. Therefore, the electrode member 70 can be made lightweight.

[0060] Figure 6 The graph is obtained by experimentally measuring the weight of the electrode components of the comparative example storage container and the weight of the electrode components 70 of the storage container 10 of this embodiment. The comparative example storage container has a structure where the electrode body is not surrounded by an insulating component, thus requiring necessary rigidity. Therefore, the weight of the electrode body tends to be large. In this respect, in the storage container 10 of this embodiment, the electrode body 71 can be reinforced using the insulating component 72, therefore, as... Figure 6 As shown, compared to the storage container of the comparative example, the weight of the electrode components in the storage container 10 of this embodiment can be reduced by approximately 400 kg. By reducing the weight of the electrode components, the storage container 10 of this embodiment can increase its load-bearing capacity compared to the storage container of the comparative example.

[0061] Furthermore, as described above, leakage current can be reduced in the electrode component 70 of this embodiment, thus making the voltage application device 90 lighter. Specifically, as Figure 6 As shown, compared to the storage case of the comparative example, the storage case 10 of this embodiment can reduce the weight of the voltage application device by about 80 kg. As a result, when viewed as a whole storage case, the storage case 10 of this embodiment can reduce the weight by about 480 kg compared to the storage case of the comparative example.

[0062] On the other hand, in the conventional storage battery, in order to obtain a higher effect on the freshness of the fresh food and the like, it is necessary to form an electric field with a higher strength. That is, it is necessary to apply a higher voltage to the electrode. In order to cope with such a requirement, the mode of the voltage applied from the voltage application device to the electrode is provided with not only a voltage mode corresponding to a low voltage but also a plurality of modes corresponding to a high voltage and the like. In order to realize the plurality of voltage modes, the capacity of the transformer corresponding thereto is necessary. As a result, in the conventional storage battery, it is necessary to mount a plurality of transformers. This becomes a main cause of increasing the weight of the voltage application device and further increasing the weight of the entire storage battery.

[0063] On the other hand, in the conventional storage battery, in order to obtain a higher effect on the freshness of the fresh food and the like, it is necessary to form an electric field with a higher strength. That is, it is necessary to apply a higher voltage to the electrode. In order to cope with such a requirement, the mode of the voltage applied from the voltage application device to the electrode is provided with not only a voltage mode corresponding to a low voltage but also a plurality of modes corresponding to a high voltage and the like. In order to realize the plurality of voltage modes, the capacity of the transformer corresponding thereto is necessary. As a result, in the conventional storage battery, it is necessary to mount a plurality of transformers. This becomes a main cause of increasing the weight of the voltage application device and further increasing the weight of the entire storage battery.

[0064] Specifically, in the conventional storage battery, as the mode of the voltage applied from the voltage application device to the electrode, for example, a voltage mode set at every 1 [kV] in the range of 2 [kV] to 7 [kV] is used, and a total of 6 voltage modes are used. In order to realize the 6 voltage modes, 6 transformers are necessary in the voltage application device. Therefore, if the weight of each transformer is "6 [kg]", the total weight of the transformers is "36 [kg] (= 6 [kg] x 6)". On the other hand, in the storage battery 10 of the present embodiment, the number of transformers 91 can be less than 6, and therefore the total weight of the transformers can be less than "36 [kg]".

[0065] Similarly, if the volume of each transformer is "0.00594 [m 3 ]", the total volume of the transformers in the conventional storage battery is "0.03564 [m 3 ] = (0.00594 [m 3 ] x 6)". On the other hand, in the storage battery 10 of the present embodiment, the number of transformers 91 can be less than 6, and therefore the total volume of the transformers 91 can be less than "0.03564 [m 3 ]".

[0066] In addition, in the storage battery 10 of the present embodiment, the insulating member 72 of the electrode member 70 is formed of resin. According to this structure, by using the above-described manufacturing method, the electrode main body 71 and the insulating member 72 can be easily integrated.

[0067] (Modified Example)

[0068] Next, a variation of the storage library 10 of the first embodiment will be described.

[0069] like Figure 7 As shown, the electrode component 70 of this modified example has an electrode body 71, a first insulating component 73, and a second insulating component 74. The first insulating component 73 and the second insulating component 74 are formed into a flat plate shape from an insulating material such as resin. The electrode body 71 is sandwiched between the first insulating component 73 and the second insulating component 74. One outer surface 710 of the electrode body 71 in the thickness direction is covered by the first insulating component 73 throughout its entire surface. The other outer surface 711 of the electrode body 71 in the thickness direction is covered by the second insulating component 74 throughout its entire surface. Each insulating component 73, 74 is fixed to the electrode body 71 by adhesive or the like.

[0070] If the electrode body 71 is sandwiched in the thickness direction using the first insulating member 73 and the second insulating member 74 as in this structure, most of the outer surface of the electrode body 71 can be covered by the first insulating member 73 and the second insulating member 74. Therefore, foreign objects are unlikely to come into direct contact with the outer surface of the electrode body 71, thus suppressing leakage current generated in the electrode body 71 through foreign objects.

[0071] <Second Implementation>

[0072] Next, the storage unit 10 of the second embodiment will be described. Hereinafter, the description will focus on the differences from the storage unit 10 of the first embodiment.

[0073] In the storage library 10 of this embodiment, the following is used: Figure 8 The multiple intermediate components 60 are shown. (As shown in the image) Figure 8 As shown, the intermediate member 60 is formed in a manner that extends along the Y direction. The intermediate member 60 has a cross-section orthogonal to the Y direction and is formed in a hat-like shape, having a flat bottom 61 and a pair of legs 62, 63 continuously formed from the bottom 61.

[0074] like Figure 9 As shown, a plurality of through holes 610 are formed on the bottom 61 of each intermediate component 60. The positions of the plurality of through holes 610 formed on the intermediate component 60 are respectively related to the bottom 61 of each intermediate component 60. Figure 3 The multiple insertion holes 720 arranged along the Y direction in the electrode component 70 shown are each in the same position. Multiple intermediate components 60 are fastened to one electrode component 70 by screwing screws or the like into the through holes 610 of the intermediate components 60 and the insertion holes 720 of the electrode component 70, which are in the same position.

[0075] A plurality of through holes 620, 630 are formed at the front end of each pair of leg portions 62, 63 of the intermediate member 60. By inserting a rivet into the plurality of through holes 620, 630, respectively, as shown in Figure 10 Each intermediate member 60 is fixed to the inner surface of the upper wall portion 41 of the storage compartment main body 20, as shown in

[0076] The same or similar effects as those of the storage compartment 10 of the first embodiment can be obtained even when the intermediate member 60 of the present embodiment is used.

[0077] In addition, by further extending each intermediate member 60 in the Y direction, as shown in Figure 11 a plurality of electrode members 70 can be fixed to each intermediate member 60. Thus, for example, even when the storage compartment main body 20 is formed long in the Y direction, the electrode members 70 can be easily arranged on the entire inner surface of the upper wall portion 41.

[0078] <Other Embodiments>

[0079] In addition, the above-described embodiments can be implemented in the following manner.

[0080] • Figure 3 The electrode member 70 shown in Figure 4 As long as the electrode member 70 is a structure in which the electrode main body 71 is surrounded by the insulating member 72, it can also have a structure in which the electrode main body 71 is fixed inside the insulating member 72 formed in a box shape by adhesion or the like.

[0081] • In the electrode member 70 shown in Figure 7 The electrode main body 71 and the insulating members 73, 74 can also be integrally formed.
