DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a view showing a main part structure used in an embodiment of the present invention, and will be described based on this. (1) is inside a refrigerator or the like, and it is preferable to use one provided with a circulation path through which the air inside (1) circulates. (2) and (3) are two electrode plates arranged facing the inner wall of the refrigerator (1) interior (1). The electrode plates (2) and (3) are a kind of pickling. A certain stainless steel plate treated with a rinsing is used, and positive and negative DC low voltages are applied between the electrode plates (2) and (3). The electrode plates (2) and (3) may be arranged at the four corners of the interior (1) and vertically without facing each other. The electrode plates (2) and (3) are, for example, those having a width of 3.5 cm and a length of 13 cm. In addition, this magnitude | size is determined by the width | variety, width | variety, etc. of the inside (1) of refrigerators. Moreover, it becomes suitable for foodstuffs by using the stainless steel board which carried out the rinse process as an electrode plate (2) and (3). If steel plates or plated plates are used for food, they are not used because they may be harmful. (4) is a deodorizing device main body. In the deodorizing device main body (4), a transformer (41) for transforming AC100V to 6V or 12V and a transformer (41) transformed to 6V or 12V from AC And at least a rectifier (42) for converting to direct current, and in addition to this, the pilot lamp (43), 6V or 12V selector switch (44), fuse (45), AC100V is selected to be turned on or off A power switch (46) and the like are provided (see FIG. 2).
[0007]
Next, the method of the present invention will be explained. Is the electrode plate (2), (3) disposed in advance facing the inner wall of the interior (1) and whether the deodorizing device body (4) is installed outside the refrigerator or the like? Or let it be built in. First, when the power switch (46) is turned on and energized, if the changeover switch (44) is on the 6V side, the positive and negative of the DC 6V low voltage are respectively between the electrode plates (2) and (3). Applied separately. Then, a low voltage direct current self-discharge action (referring to a state where air is gradually discharged in the present invention) is generated, and air with a changed potential circulates in the chamber (1), Increasing the potential reduces the potential release of fresh foods such as meat and vegetables, makes it possible to maintain the freshness by delaying the change of fresh food in the warehouse (1), and to prevent the generation of bad odors in fresh food There is also an effect of pressing and deodorizing the unpleasant odor in the chamber (1) to the extent that it does not matter due to the change in potential. When the DC low voltage used in the present invention is 6 V, 0.15 mA or less, the effect is extremely reduced, and when it is 12 V, 0.25 mA or more, there is a problem in safety to the human body. Also, by using batteries or car batteries as a power source and placing the electrode plates (2) and (3) in a container for storing fresh food at camping or outdoors, the internal deodorization or perishment of fresh food Can be delayed.
[0008]
Next, an experiment for confirming the effect of the method of the present invention is performed. First, 10 units each having the electrode plates (2) and (3) of this embodiment attached to the refrigerator and those not attached are prepared. Prepare a refrigerator with a size of 500 liters and a width of 83 cm. When the electrode plates (2) and (3) are placed in the chamber (1), they are placed facing the inner wall, and a 0.15 mA current of 6V is applied to the electrode plates (2) and (3). The experiment was conducted. And recruit 10 monitors, put the following samples under the same conditions as a pair of the refrigerator with the electrode plate (2), (3) of this embodiment and the refrigerator as it is in each monitor, We had you check comparison experiment of deodorization effect and freshness. As experimental samples to be placed in the refrigerator, 1) the same vegetables such as lettuce, leek, and apple were purchased and divided in half. 2) Garlic was added to the chicken meat to make raw food for yakiniku and divided into equal amounts. 3) Ice was made by freezing from water with an ice maker. Next, as a method for checking the deodorizing effect and freshness comparison experiment, the samples (1) to 3) in the chamber (1) were checked for changes for 10 days. As this content, at the same time every day, record whether or not the bad odor in the chamber (1) is felt, whether or not the samples 1) to 3) have changed, and if so, the state is recorded.
[0009]

As shown in the above table, the effect of the method of the present invention is that the odor in the storage (1) gradually disappears and the odor is not noticeable from the third day, and the deodorizing effect is sustained, compared to the case of nothing. It was confirmed that it was demonstrated. And when it is stored lettuce, leeks, in the internal sample 1) of vegetables of apple, etc. (1), the effect of keeping the freshness was confirmed to have been demonstrated to delay the corruption of deodorizing and vegetables. In addition, although the raw sample 2) for grilled meat and the ice sample 3) of the ice maker were observed for 10 days, there was almost no change. In addition, when the electrode plates (2) and (3) were touched by mistake, a weak current flowed, but it did not feel strong enough to adversely affect the human body. Furthermore, when placing the electrode plates (2) and (3) in the refrigerator, they can be installed anywhere without taking up space with a compact design, so hold them in your hand and stick them to the inner wall of the cabinet (1) Simply set up. Further, when the effect is lowered, if the surface is wiped cleanly on the electrode plates (2) and (3), the original effect can be exhibited immediately. When the surface of the electrode plates (2) and (3) is not cleaned, it may be replaced. At this time, the electrode plates (2) and (3) are peeled off by hand. The other parts can be used as they are without replacement. Moreover, since there is no moving part in the above embodiment, there is almost no failure, and the electricity cost when a 0.15 mA current of 6 V is passed through the electrode plates (2) and (3) is 6 yen per month. It was confirmed that it was very economical for 9 yen.
