[0003] [Patent Document 1] JP 2019-27651 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the storage (refrigerator) described in Patent Document 1, the electrode unit 80 is embedded inside the upper insulating partition wall 17a (paragraph 0019, FIG. 2). Therefore, there is room for improvement in the insulating performance compared to a structure in which the electrode unit 80 is not embedded. The problem that the present disclosure aims to solve is to provide a storage facility having excellent insulation performance. [Means for solving the problem]

[0005] The storage facility of the present disclosure comprises a storage chamber, a container disposed on the floor of the storage chamber, one or more shelves disposed above the container, and an electrode disposed between an upper surface of the lowest of the one or more shelves and the floor of the storage chamber, for generating an electric field in the interior space of the container.

[0007] Hereinafter, a form for carrying out the present disclosure (referred to as an embodiment) will be described with reference to the drawings. In the following description of one embodiment, other embodiments applicable to the one embodiment will also be described as appropriate. The present disclosure is not limited to the following one embodiment, and different embodiments can be combined with each other or modified as desired without significantly impairing the effects of the present disclosure. In addition, the same symbols will be used for the same members, and duplicate descriptions will be omitted. Furthermore, the same names will be used for members having the same functions. The contents shown are merely schematic, and for the sake of illustration, changes may be made from the actual configuration within a range that does not significantly impair the effects of the present disclosure, and some members may be omitted or modified between drawings. In addition, the same embodiment does not necessarily need to have all the configurations.

[0008] 1 is a front view of a storage cabinet 10 according to the present disclosure. In the illustrated example, the storage cabinet 10 is a refrigerator, but it may be a warming cabinet, a constant temperature storage cabinet, etc. The storage cabinet 10 includes a door 1 that can rotate around an axis at both left and right ends of the storage cabinet 10, and drawer doors 2, 3, 4, and 5.

[0009] 2 is a cross-sectional view taken along line AA in FIG. 1. The storage facility 10 includes a metal housing 30 (so-called outer box) that defines the exterior of the storage facility 10. The storage facility 10 also includes a communication unit 31 that is arranged outside the housing 30 and is capable of wireless communication with an external device of the storage facility 10. The communication unit 31 is arranged at the top end of the rear side of the storage facility. The communication unit 31 is connected to a control device 100 (FIG. 11) described below. The control device 100 transmits, for example, the status of the storage facility 10 (such as the temperature of the storage room 11) to the external device via the communication unit 31. Note that the communication unit 31 does not need to be arranged entirely outside the housing 30, and only a portion of the communication unit 31, such as an antenna portion constituting the communication unit 31, may be arranged outside the housing 30.

[0010] The storage facility 10 includes storage chambers 11, 12, 14, and 15 inside a housing 30. That is, the housing 30 is disposed outside the storage chambers 11, 12, 14, and 15. The storage chambers 11, 12, 14, and 15 are partitioned by an inner box made of resin, for example, and are formed inside the inner box. The doors 1, 2, 4, and 5 close openings formed on the front sides of the storage chambers 11, 12, 14, and 15. By opening the doors 1, 2, 4, and 5, the front sides of the storage chambers 11, 12, 14, and 15 are opened, and food and the like can be put in and taken out of the storage chambers 11, 12, 14, and 15. Although not shown, food and the like can be put in and taken out of a storage chamber (for example, an ice-making chamber) formed inside the storage facility 10 even when the door 3 is opened. The storage compartment 11 is, for example, a refrigerator compartment, the storage compartment 12 is, for example, a quick-freezing compartment, the storage compartment 14 is, for example, a freezing compartment, and the storage compartment 15 is, for example, a vegetable compartment.

[0011] The storage chamber 11 is provided with one or more shelves 21. The shelves 21 are arranged above the containers 28 (FIG. 4). The shelves 21, including the shelf 23 arranged at the lowest level, are made of a material that is permeable to an electric field E (described later). Such materials are, for example, polystyrene, resins such as ABS resin, glass, etc. In the illustrated example, there are multiple shelves 21, but there may be only one. Foods and the like are placed on the shelves 21. Shelves 22 other than the shelf 23 arranged at the lowest position among the shelves 21 are supported on guides 24 formed on the left and right side surfaces of the storage chamber 11. Therefore, a user can freely remove the shelves 22 depending on the height of, for example, food, etc., to be stored in the storage chamber 11.

[0012] FIG. 3 is a perspective view of the shelf 23 arranged at the lowest position. When only one shelf 21 is provided, the shelf 21 arranged as the only one (the shelf 21 closest to the container 28) is the shelf 23 arranged at the lowest level. Unlike the shelf 22 (FIG. 2), the shelf 23 (lowest shelf) is fixed to the storage chamber 11 by a fixing device 53 that cannot be easily removed by the user. In this manner, the electrode 41 (described later) arranged on the lower side of the shelf 23 can be made difficult to touch by the user. In the illustrated example, the fixing device 53 is a screw or bolt or other screw-threaded member. The shelf 23 is fixed to the storage chamber 11 on the rear side of the storage chamber 11 by inserting the fixing device 53 (screw-threaded member) downward through the insertion hole 52 (see also FIG. 9A described later) that opens upward.

[0013] Note that the fastener 53 is not limited to a screw member, and may be, for example, a claw, a fastener forming a snap-fit ​​structure, an adhesive, etc. However, from the viewpoint of improving maintainability by repair personnel, a fastener that cannot be easily removed by general users but is removable by repair personnel (for example, a screw member, a claw, a fastener forming a snap-fit ​​structure, etc.) is preferable.

[0014] Fig. 4 is an enlarged view of part B in Fig. 2. For convenience of illustration, Fig. 4 only shows an electric field E directed downward from electrode 41. However, in reality, electric field E is generated, for example, in multiple directions toward a metal member that serves as an opposing electrode when viewed from electrode 41. The metal member here refers to a metal member provided in storage 10, such as a metal tray that can be placed in at least one of housing 30 (Fig. 2) and storage chambers 11, 12, 14, and 15. The metal member is preferably connected to earth.

[0015] A container 28 is disposed in the storage chamber 11. The container 28 is fixed to the storage chamber 11 by a fastening member such as a bolt or a screw. The container 28 is fixed to the floor of the storage chamber 11, but may be fixed to the back surface, left or right side surface, etc. of the storage chamber 11. The container 28 has a door 26 that can be opened and closed on the front side. By opening the door 26, an opening is formed on the front side of the container 28, and food or the like can be stored in the internal space 20 of the container 28. The internal space 20 is, for example, a chilled room in which at least one of fish or meat can be stored. The chilled room is, for example, a room with a set temperature of 0°C or higher and 2°C or lower. Details will be described later with examples, but by storing food such as fish or meat in the internal space 20 where an electric field E is generated, the freshness of the food can be maintained for a long period of time.

[0016] The storehouse 10 includes an electrode 41 disposed between an upper surface 231 of the shelf 23 disposed at the lowest position among the shelves 21 and a floor surface 111 of the storage room 11. The electrode 41 generates an electric field E in the internal space 20 of the container 28. By generating the electric field E by the electrode 41, the freshness of, for example, fish, meat, vegetables, etc. stored in the internal space 20 can be maintained for a long period of time, as will be described in detail later.

[0017] Although details will be described later, in the present disclosure, the electrode 41 may be disposed between the upper surface 231 and the floor surface 111. For example, the electrode 41 may be disposed inside the shelf 23 slightly lower than the upper surface 231. Furthermore, the electrode 41 may be disposed outside or inside (preferably outside) the container 28 disposed between the upper surface 231 and the floor surface 111, or may be disposed inside a resin wall surface (including left and right side walls, upper and lower side walls, front and rear side walls) constituting the container 28. Furthermore, the extending direction of the electrode 41 may be the front-rear direction, the left-right direction, or the up-down direction of the storage facility 10, for example, if the electrode 41 is a flat plate-shaped electrode.

[0018] The method for generating the electric field E is not particularly limited, but for example, the electric field E can be generated by applying a voltage to the electrode 41. The conditions of the voltage and current applied to the electrode 41 are not particularly limited as long as the conditions are such that the electric field E can be generated. For example, the voltage can be 1000 V or more and 4000 V or less, and the voltage can be 10 mA or more and 1 A or less. The applied voltage and current may be either DC or AC.

[0019] The electrode 41 is disposed in the storage chamber 11. Meanwhile, as described above, the metal housing 30 is disposed outside the storage chamber 11, and the communication unit 31 is disposed outside the housing 30. Therefore, the metal housing 30 is disposed between the electrode 41 and the communication unit 31. With such an arrangement, it is possible to avoid radio wave interference between the frequency band of the voltage and current applied to the electrode 41 and the frequency of the radio waves used by the communication unit 31 due to, for example, noise generated in switching.

[0020] The time when the electric field E is generated (time when the current is applied to the electrode 41) is not particularly limited, but from the viewpoint of improving the freshness of the food stored in the internal space 20, it is preferable to generate the electric field E at all times (for example, at all times when the doors 1, 26 are closed). However, the generation of the electric field E may be switched on and off according to the user's desire, for example, by the user operating an operation unit such as an operation button. Also, it is preferable not to generate the electric field E (to stop the generation of the electric field E) when at least one of the door 26 closing the front opening of the container 28 and the door 1 closing the front opening of the storage chamber 11 is open. The opening and closing of the doors 1, 26 can be detected, for example, by using a sensor (not shown) installed in the storage 10 to detect the opening and closing of the doors 1, 26.

[0021] FIG. 5 is a perspective view of the electrode 41. The electrode 41 has, for example, a flat plate shape, but may also be a block shape. The width of the electrode 41 in the left-right direction is the same as or slightly shorter than the width of the container 28 in the left-right direction. The length (depth) of the electrode 41 in the front-rear direction is approximately half the length (depth) of the container 28 in the front-rear direction. The electrode 41 is disposed above the container 28 near the center in the front-rear direction of the storage 10. A lead wire 44 connected to the electrode main body 43 (FIG. 6B) is provided at the rear end of the electrode 41. The lead wire 44 is connected to a power supply device (not shown) that drives the storage 10.

[0022] FIG. 6A is a top view of the electrode 41 shown in FIG. 5. FIG. 6B is a cross-sectional view taken along the line CC in FIG. 6A. The electrode 41 includes a support member 42 and an electrode body 43. The support member 42 is made of a material that is permeable to the electric field E (FIG. 4). The material is, for example, a non-conductive resin (for example, polyethylene, polypropylene, styrene, ABS resin, etc.), glass, rubber, etc. The electrode body 43 includes the electrode body 43 that is supported by the support member 42 and to which a voltage is applied. The electrode 41 has such a structure, which makes it easy to arrange the electrode body 43. The electric field E can be generated at the installation location of the electrode 41. In the illustrated example, the electrode body 43 is contained in the support member 42. This makes it possible to prevent a user from touching the electrode body 43 to which a voltage is applied.

[0023] The electrode body 43 is made of, for example, a conductive metal and has, for example, a rectangular flat plate shape (foil shape). However, the electrode body 43 may also have, for example, a linear shape (wire shape), a punched metal (porous metal plate shape), a circular flat plate shape, etc. The support member 42 may be a flexible member.

[0024] The electrode 41 can be manufactured by, for example, insert molding. Specifically, for example, while the electrode body 43 is held in a mold, the constituent material of the support member 42, such as resin, is poured in so as to encase the electrode body 43, thereby enabling the electrode body 41 to be encapsulated in the support member 42. Alternatively, the electrode body 43 can be encapsulated by, for example, sandwiching the electrode body 43 between two plates made of the constituent material and bonding (welding, etc.) the plates together in the portion surrounding the electrode body 43.

[0025] Returning to FIG. 4, the electrode 41 is disposed between the upper surface 281 of the container 28 fixed to the storage chamber 11 and the lower surface 232 of the shelf 23 fixed to the storage chamber 11. In this manner, the electrode 41 can be disposed between the container 28 and the shelf 23, both of which are fixed. This prevents the user from removing the container 28 and the shelf 23, and thus prevents the user from touching the electrode 41. In addition to the electric field E directed toward the internal space 20, the electric field E also directs toward the shelf 23, which is made of a material that is permeable to the electric field E, such as resin or glass. Therefore, the electric field E can be generated on the food and the like placed on the shelf 23, including the shelf 23.

[0026] Between upper surface 281 of container 28 and lower surface 232 of shelf 23, structure 27 is formed at least on the front side of storage cabinet 10 to prevent the fingers of a user using storage cabinet 10 from getting in. Having structure 27 can prevent a user from getting their fingers in between upper surface 281 and lower surface 232 from the front side of storage cabinet 10, and can prevent a user from touching electrode 41 arranged between upper surface 281 and lower surface 232.

[0027] In the example of FIG. 4, structure 27 is a structure in which a gap of a height that prevents a user's fingers from entering (for example, 5 mm or less) is formed between upper surface 281 and lower surface 232 at least on the front side of storage 10. However, structure 27 may be a structure in which upper surface 281 and lower surface 232 are in close contact with each other, thereby forming no gap. Furthermore, structure 27 may be formed at least on the front side of storage 10 that catches the user's eye, and, for example, structure 27 does not need to be present over the entire area between upper surface 281 and lower surface 232. For example, a gap of a height of, for example, 1 cm may be formed between upper surface 281 and lower surface 232 in a portion other than the front side.

[0028] In the example of the present disclosure, in order to provide a large front opening of container 28, the upper end of door 26 (front end of upper surface 281) is disposed close to lower surface 232. Therefore, there is almost no gap at the front end of container 28. On the other hand, on the rear side of door 26, electrode 41 is disposed between upper surface 281 and lower surface 232, so the gap between upper surface 281 and lower surface 232 has a certain height.

[0029] Fig. 7 is a perspective view of container 28 to which electrode 41 is fixed. Fig. 8 is a perspective view of container 28 shown in Fig. 7 with electrode 41 removed. In Figs. 7 and 8, part of the structure of electrode 41 is omitted for simplicity of illustration.

[0030] A plurality of ribs 212 extending in the left-right direction, for example, are formed on the upper surface 281 of the container 28. The rib 212 has a step portion 213 that is lower than the height of the left and right ends. One step portion 213 is provided on each side, and the space between the left and right step portions 213 is lower than both the left and right ends. The electrode 41 is disposed in this lowered portion. As a result, the electrode 41 is supported on the upper surface 281 of the container 28 via the upper ends of the ribs 212. By being supported on the upper surface 281, the electrode 41 can be exposed by a repair person removing the shelf 23 (FIG. 4) during maintenance, making it easier for the repair person to access the electrode 41. In addition, by disposing the electrode 41 between the two step portions 213, rattling of the electrode 41 can be suppressed.

[0031] Fig. 9A is a top view of shelf 23 (lowest shelf) according to another embodiment. Fig. 9B is a cross-sectional view taken along line DD in Fig. 9A. As described above, shelf 23 is made of, for example, resin, glass, etc. Electrode 41 is integrated with shelf 23. By integrating electrode 41 and shelf 23, the number of parts can be reduced. Also, the space in storage chamber 11 that houses the electrode and shelf 23 in which food and the like can be stored can be made larger.

[0032] The shelf 23 has a plurality of claws 234 on its lower surface. For example, the electrode body 43 having a flat plate shape is hooked onto the plurality of claws 234, whereby the electrode body 43 is supported on the shelf 23. Furthermore, for example, a flat plate-shaped support member 42 is fastened to the lower surface of the claws 234 so as to cover the electrode body 43. This allows the electrode body 43 to be contained within the shelf 23, making it possible to prevent the user from touching the electrode body 43.

[0033] The electrode 41 itself, including the support member 42 and the electrode body 43 , may be fixed to the lower surface of the shelf 23 .

[0034] 10 is an enlarged view of the vicinity of container 28 according to another embodiment. Electrode 41 is disposed on the rear side of container 28. For example, plate-shaped electrode 41 extends in the up-down direction (vertical direction) of storage 10, in the same direction as the rear wall surface of container 28. Therefore, the electric field E generated by electrode 41 is generated in the front-rear direction of storage 10, not in the up-down direction in FIG. 4 above. By disposing electrode 41 in this position, electric field E can be generated in internal space 20. Electrode 41 is disposed, for example, on the outside of the rear surface of container 28 and inside storage chamber 11 (forward of the rear wall of storage chamber 11).

[0035] The storage facility 10 includes a control device 100 (FIG. 11) that stops the generation of the electric field E when the door 1 is open. As described above, the door 1 closes the opening formed on the front side of the storage room 11. The electric field E generated from the electrode 41 is directed toward the door 1 that is in front of the electrode 41. Therefore, by stopping the generation of the electric field E by the control device 100 when the door 1 is opened (i.e., in the open state), it is possible to prevent the electric field E from leaking to the outside when the door 1 is open. In particular, when the door 26 is made of a material that is permeable to the electric field E (e.g., resin, glass, etc.), it is preferable to include such a control device 100. On the other hand, when the door 26 is made of a material that is not permeable to the electric field E (e.g., metal), such a control device 100 may not be included.

[0036] FIG. 11 is a block diagram showing a specific hardware configuration of the control device 100 that controls the operation of the storage 10 (e.g., control of current supply to the electrode 41). The control device 100 is configured to include, for example, a central processing unit (CPU) 1001, a random access memory (RAM) 1002, a read only memory (ROM) 1003, an interface (I / F) 1004, and a bus 1005. The CPU 1001, the RAM 1002, the ROM 1003, and the interface (I / F) 1004 are connected, for example, via the bus 1005. The control device 100 is realized by developing a predetermined control program (e.g., a method of current supply to the electrode 41) stored in the ROM 1003 into the RAM 1002 and executing it by the CPU 1001. Signals and information are exchanged between the control device 100 and various devices (e.g., servers), an external network, and the like, in terms of hardware, through the interface (I / F) 1004.

[0037] In another embodiment, the control device 100 stops generation of the electric field E (FIG. 4) while the communication unit 31 (FIG. 2) is communicating with an external device (e.g., a mobile communication terminal, etc.). This makes it possible to suppress interference between the radio waves generated from the communication unit 31 and the electric field E, and to suppress malfunctions of the external device and the storage facility 10.

[0038] 12 is an enlarged view of the vicinity of container 28 according to another embodiment. Electrode 41 is disposed between lower surface 282 of container 28 and floor surface 111 of storage chamber 11. By disposing electrode 41 in this position, electric field E can be generated in internal space 20. The upper surface of electrode 41 is held down by rib 214 formed on lower surface 282. This makes it possible to prevent electrode 41 from rattling simply by placing electrode 41 on floor surface 111. However, electrode 41 may be fixed to floor surface 111.

[0039] The effect of generating the electric field E by the electrode 41 was verified by the following example.

[0040] First, as Example 1, a storage container 10 was produced in which the electrode 41 was arranged at the position shown in Fig. 4. Also, as Comparative Example 1, a storage container similar to Example 1 was produced except that the electrode 41 was not arranged.

[0041] Next, three horse mackerel were prepared, and the amounts of inosinic acid (IMP), inosine (HxR), and hypoxanthine (Hx) in one of the horse mackerels were measured, and the K value (initial K value) was calculated. The K value is an index of freshness, and the lower the K value, the fresher the fish. After death, inosinic acid, a flavor component, is broken down, and hypoxanthine is produced via inosine. The K value (%) was calculated based on the following formula (1). K value = (HxR amount + Hx amount) / (IMP amount + HxR amount + Hx amount) x 100 ... Formula (1)

[0042] Of the remaining two, one horse mackerel was stored in the internal space 20 for three days using the storage facility 10 of Example 1. The internal space 20 was controlled for temperature and humidity as a chilled room, and an electric field E was constantly generated. The electric field E was generated by applying a DC voltage of 2000 V to the electrode 41 and passing a DC current of 100 mA. The doors 1 and 26 were kept closed for three days.

[0043] Furthermore, the remaining one was stored in the internal space 20 using the storage container of Comparative Example 1 under the same conditions as in Example 1, except that the electric field E was not generated.

[0044] After 3 days, horse mackerel were taken out from the storage facility 10 of Example 1 and the storage facility of Comparative Example 1, and the K values ​​of both horse mackerel were calculated in the same manner as for the initial K value.

[0045] FIG. 13 is a graph showing the K value when a voltage of 2000V was used. "Initial" is the K value of the fish before the start of the verification (before the start of storage; before the application of the electric field E). "With electric field" is the K value of Example 1, in which an electric field E of 2000V was applied. "Without electric field" is the K value of Comparative Example 1, in which the verification was performed under the same conditions as Example 1, but no electric field E was applied. For all of the cases, initial, with electric field (Example 1), and without electric field (Comparative Example 1), the numbers inside the graph are the calculated K values.

[0046] In both Example 1 and Comparative Example 1, the K value increased after three days of storage, and the freshness decreased from the initial value. However, the degree of decrease differed, with Example 1 only increasing to a value (34.56) that was about 10% higher than the initial K value (31.17). In contrast, Comparative Example 1 increased to a value (37.23) that was about 20% higher. Therefore, it was confirmed that the electric field E can reduce the decrease in freshness to about half.

[0047] Next, three new horse mackerels were prepared, and the K value was measured in the same manner as in Fig. 13. However, the voltage for generating the electric field E was changed to 3000V instead of 2000V in Example 1.

[0048] Fig. 14 is a graph showing the K value when a voltage of 3000 V is used. "Initial" is the same as Fig. 13 above, and "with electric field" is the K value of Example 2 in which an electric field E of 3000 V was applied. "Without electric field" is the K value of Comparative Example 2 in which verification was performed under the same conditions as Example 2, but in which the electric field E was not applied.

[0049] In both Example 2 and Comparative Example 2, the K value increased and the freshness decreased after three days of storage. However, the degree of decrease was different, and under the verification conditions shown in FIG. 14 (for example, the temperature in the room where the storage facility 10 was placed, etc.), Example 2 had a value (48.84) that was about 35% higher than the initial K value (32.21). In contrast, Comparative Example 2 had a value (52.81) that was about 64% higher. Therefore, compared to the verification conditions in FIG. 13 above, Example 2 and Comparative Example 1 had a large decrease in freshness, but when Example 2 and Comparative Example 2 verified under the same conditions were compared, it was confirmed that the electric field E could reduce the decrease in freshness to about half, as in FIG. 13.
