Hereinafter, some embodiments according to the present invention will be described by way of example with reference to the drawings. This embodiment is merely an example embodying the configuration of the present invention, and various design changes can be made without departing from the matters described in the claims.
As shown in FIG. 1 or FIG. 2, the electric field forming panel A according to the present invention includes a planar electrode 11 as an electrode in which a panel-shaped main body portion 1 is formed in a flexible mesh shape. It is comprised from the protective sheet 12 as a surface layer material which surrounds the plane electrode 11, and the insulating material 13 of the insulating material arrange | positioned in any one between this protective sheet 12 and the plane electrode 11. FIG.
The planar electrode 11 is made of a conductive metal material having a mesh shape of 30 to 50 mesh, and is formed into a round shape, a rectangular shape, or a round donut shape or a rectangular donut shape with a gap at the center. In the present embodiment, the planar electrode 11 is a stainless steel net having a mesh number of 40 mesh, and is formed in a rectangular shape. The flat electrode 11 is meshed to be flexible so that it can be easily attached to a refrigerator or the like. Further, the size (area) of the planar electrode 11 is 1 m × 2 m at the maximum, and it may be matched with the size of the wall surface or door portion of the storage unit such as a refrigerator to be attached in a range smaller than that. If the size of the wall surface or door portion to be attached exceeds 1 m × 2 m, the electric field space can be widened by using a plurality of electric field forming panels A. The flat electrode 11 formed in a round donut shape or rectangular donut shape with a gap in the center is applied to the case where a glass window is provided in a door portion of a refrigerator or the like.
The protective sheet 12 is made of a material that does not react to water droplets or condensation in consideration of the temperature environment of the attachment destination, such as cloth or vinyl. In this embodiment, the protective sheet 12 employs a flame retardant tent fabric. Note that the protective sheet 12 is subjected to a thermocompression treatment as shown in FIG. 2 in order to reliably avoid discharge and electric leakage at the time of implementation or to reduce electric shock due to contact when surrounding the flat electrode 11. It is preferable to form the electric field forming panel A by providing a thickness in at least the direction in which the electric field space is to be formed, that is, the electric field forming direction.
The insulating material 13 is formed of a flexible insulating material such as a synthetic resin. In the present embodiment, the insulating material 13 is made of high-density polyurethane. The insulating material 13 is disposed on either one of the protective sheet 12 and the planar electrode 11, and specifically, disposed on the opposite side of the electric field forming direction in contact with the planar electrode 11. The size (area) is preferably a size corresponding to the planar electrode 11. The reason for adopting a flexible material for the insulating material 13 is to enable easy attachment as with the reason for adopting a flexible material for the planar electrode 11.
In addition, when attaching the electric field forming panel A to the storage unit wall surface of the storage or the door portion of the refrigerator, rather than applying a hook using a double-sided tape or the like, the planar electrode 11 at the end is surrounded and laminated. It is preferable to apply the insulating rivet 12a to a portion formed only from the protective sheet 12 having a thickness. Attaching through the insulating rivet 12a is convenient for preventing accidental disconnection.
Next, the application of a voltage to the planar electrode 11 to be performed when the electric field forming panel A is performed will be described. In this invention, in order to achieve the structure which does not require special power supply equipment and a power supply device, it is a subject, Therefore Under such conditions, electric field space is formed using a commercial power supply frequency. For this reason, the range of the electric field space in which it is possible to surely cause supercooling in which water becomes unfrozen at a temperature below the freezing point is determined based on the following electrical theory.
Assuming that the electric field forming panel A is an opposing planar electrode, the capacitance C [F] can be expressed by the following formula 1.

The electric charge Q [C] stored in the electric field forming panel A can be expressed by the following formula 2.

The electric field amount (electric field strength) E [V / m] at a position r (m) away from the charge Q [C] can be expressed by the following Equation 3.

An alternating current I [A] flowing through a capacitor (electric field space) having a capacitance C can be expressed by the following mathematical formula 4.

Based on these electrical theories, when a voltage of 1 kV to 5 kV is applied to the planar electrode 11 of the electric field forming panel A with a sine waveform of a frequency of 48 Hz to 62 Hz, the electric field on the side where the insulating material 13 is not disposed. An electric field space having a considerable electric field strength is formed within 3 m from the surface of the planar electrode 11 in the forming direction. If the electric field strength of the formed electric field space is 0.3 kV / m to 15 kV / m, the electric field space is a general refrigerator refrigeration environment, even if the shape of the storage and the arrangement of stored items are taken into consideration- At 5 ° C. to 0 ° C., the water is adjusted to a non-freezing state and supercooling occurs. In the present invention, it is necessary to control the level of the AC applied voltage V [V] and the charge Q [C] stored in the electric field forming panel A. These controls can be achieved by using a known control device.
The electric field forming panel A uses the insulating rivet 12a at the end, and the side on which the insulating material 13 is arranged, that is, the surface of the protective sheet 12 opposite to the electric field forming direction, Install it in contact with the door. In addition, the size of the electric field forming panel A is determined within the range of 1 m × 2 m at the maximum because the size of the flat electrode 11 matches the size of the housing wall surface or door portion to be attached. Is determined. If the accommodating part wall surface or door part to be attached exceeds 1 m × 2 m, an electric field may be formed by using a plurality of electric field forming panels A.

Example of application to commercial refrigerators, laboratories, and refrigerators for medical institutions As shown in Fig. 3, the storage environment of the commercial refrigerator B is supercooled so that the water becomes unfrozen at -5 ° C to 0 ° C. When it is going to arrange in the state which happens, it is preferable to attach the panel A for electric field formation to the door part B1 of the refrigerator B for business use. This is because it can be easily attached and detached. Specifically, the surface of the protective sheet 12 opposite to the electric field forming direction, which is the side on which the insulating material 13 of the electric field forming panel A is disposed, is brought into contact with the door portion B1 of the commercial refrigerator B, and the end rivets Install using. Moreover, when it is going to return the commercial refrigerator B to a normal environment, what is necessary is just to remove the electric field formation panel A from the door part B1 of the commercial refrigerator B including a power cord.
Also, when the housing portion of the commercial refrigerator B is to be in an environment in which overcooling occurs, the electric field forming panel A is attached to the door portion B1 of the commercial refrigerator B, and then the electric field forming panel A is supplied from the power source through the control device. A voltage of 1 kV to 5 kV is applied to the flat electrode 11 with a sine waveform having a frequency of 48 Hz to 62 Hz. Then, an electric field space having an electric field strength of 0.3 kV / m to 15 kV / m is formed within 3 m from the surface of the planar electrode 11 in the electric field forming direction. A space under an electric field having an electric field strength of 0.3 kV / m to 15 kV / m is an environment where supercooling occurs in which water becomes unfrozen at -5 ° C to 0 ° C.

Example of application to a prefabricated refrigerator or container having a large storage volume When the storage environment of the container C is to be adjusted to a state where supercooling occurs in which water is unfrozen at -5 ° C to 0 ° C, It is preferable to attach the electric field forming panel A to the container wall surface C1 of the container C. If the accommodating part wall surface C1 to be attached exceeds 1 m × 2 m, a plurality of electric field forming panels A are used as shown in FIG. 4 (a). Since the method for adjusting the container C environment of the container C to a state in which overcooling occurs is the same as that in the first embodiment, the description thereof is omitted. Then, by using only a plurality of electric field forming panels A, the entire container C can be made into an environment in which supercooling occurs in which the water becomes unfrozen at a temperature below the freezing point. is there. When a plurality of electric field forming panels A are used in a prefabricated refrigerator or the like having a depth or width of 3 m or more, as shown in FIG. 4 (b), if the electric field forming panels A are installed so as to face each other, An electric field space having an electric field strength of 0, 3 kV / m to 15 kV / m can be obtained without leaving any space.
In addition, applying the electric field forming panel A according to the present invention to a refrigerator for general households is not excluded. When the electric field forming panel A according to the present invention is applied to a refrigerator for general household use, the environment of the storage unit for storing vegetables, meat, fish, etc. is supercooled so that the water becomes unfrozen at a temperature below the freezing point. It is possible to prepare a state in which food is generated, and it is possible to easily prevent the deterioration of food freshness and spoilage at home.
Therefore, the electric field forming panel A is suitable for various applications ranging from household refrigerators to large-volume containers to prefabricated refrigerators. It can be easily used as a means for adjusting to a state where supercooling occurs. Further, no special power supply equipment or power supply device is required, and no special insulation measures are required. Since it is easy to install, it can be easily used in more and more applications. An electric field space can be formed without requiring special handling from the user, and the environment in which the electric field space is formed is supercooling in which water is in an unfrozen state at -5 ° C to 0 ° C. It can be used in a normal environment, from a household refrigerator to a container with a large volume, a prefabricated refrigerator, etc., or used in an environment where overcooling occurs.
