[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a view showing a main part structure used in an embodiment of the present invention.
(1) is the inside of a refrigerator or the like, and it is preferable to use a refrigerator provided with a circulation path through which the air in the refrigerator (1) circulates. (2),
(3) is two electrode plates arranged opposite to the inner wall of the refrigerator (1), such as a refrigerator, and the electrode plates (2) and (3) are subjected to a rinsing treatment which is a kind of pickling. A stainless plate 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 chamber (1) and not vertically, without facing each other. The size of the electrode plates (2) and (3) is, for example, 3.5 cm.
And a length of 13 cm is used. The size is determined by the size and width of the refrigerator (1).
In addition, by using a stainless steel plate subjected to a rinsing treatment as the electrode plates (2) and (3), it becomes suitable for food. If a steel plate, a plated plate, or the like is used for food, there is a risk of harm. (4) is a deodorizing device main body.
A transformer (41) for transforming the voltage to V or 12V, and a rectifier (42) for converting the voltage transformed to 6V or 12V by the transformer (41) from AC to DC are further provided. 43), 6V or 12V switch (44), fuse (45), AC1
A power switch (46) for selecting whether to apply or cut off 00V is provided (see FIG. 2).

Next, the method of the present invention will be described. First, the electrode plates (2) and (3) face the inner wall of the chamber (1) in advance.
And the deodorizing device main body (4) is installed outside the refrigerator or the like or is built in. First, turn on the power switch (46) and turn on the power.
If it is on the side, a plus and minus of a DC 6V low voltage is separately applied between the electrode plates (2) and (3). Then, a low-voltage direct current self-discharge action (refers to a state of being gradually discharged in the air in the present invention) occurs, and the air having the changed potential circulates in the compartment (1), and the air in the compartment (1) By increasing the potential, the release of the potential of fresh food such as meat and vegetables is reduced, and the change of the fresh food in the refrigerator (1) can be delayed to maintain the freshness, and the generation of offensive odor of the fresh food can be prevented. In addition to the suppression, there is an effect that the unpleasant odor in the compartment (1) can be deodorized to the extent that it does not matter by the change in the potential. The low DC voltage used in the present invention is 6 V,
When it becomes 0.15mA or less, the effect is extremely reduced, 12V, 0.25mA
The above causes a problem in safety for the human body. In addition, a battery or a car battery is used as a power source, and an electrode plate (2),
By disposing (3), it is possible to delay the deodorization of the inside and the decay of fresh food.

Next, an experiment for confirming the effect of the method of the present invention is performed. First, ten refrigerators each having the electrode plates (2) and (3) of the present embodiment mounted thereon and one not mounting the same are prepared. A refrigerator having a size of 500 liters and a width of 83 cm is prepared. When the electrode plates (2) and (3) are arranged in the chamber (1), they are arranged so as to face the inner wall, and the electrode plates (2) and (3) have a voltage of 0.1 V of 6V.
The experiment was performed with a current of 5 mA. Then, 10 monitors were recruited, and a refrigerator provided with the electrode plates (2) and (3) of the present embodiment and a refrigerator as it were were paired for each monitor, and the following samples were prepared under the same conditions. We asked them to check the experiment for comparing the deodorant effect and freshness. As the experimental samples to be put in the refrigerator, 1) The same vegetables such as lettuce, chive, apple, etc. were purchased and halved. 2) Garlic was added to chicken meat and mixed to make raw meat for grilled meat. 3) I made ice by freezing from water with an ice maker. Next, as a method of checking the comparative experiment between the deodorant effect and freshness, the change in the samples 1) to 3) placed in the refrigerator (1) was checked for 10 days. At the same time every day, whether or not a bad smell in the refrigerator (1) is sensed, whether or not the samples in 1) to 3) have changed, and if so, the state is recorded.

[0009]

[Table 1]Conventional method of the present invention Number of people who felt odor Sample change Number of people who felt odor Sample change Day 1 10 people 10 days 2 day 3 people 10Day 3 0 people 10 people Day 4 0 None 10 Lettuce begins to melt Day 5 0 None 10 Leek begins to melt6th day 0 no people 10 people Day 7 0 people 10 peopleDay 8 0 people Lettuce, leek discoloration 10 people leek can not be used 9th day 0 people 10 people lettuce not availableApple wrinkles Day 10 0 people Lettuce, Chinese chive 10 people Some cannot be used

[0010] As shown in the above table, the effect of the method of the present invention is as follows. It was confirmed that the odor effect was continuously exhibited. Lettuce, leek,
It was confirmed that when the vegetable sample 1) such as an apple was stored in the refrigerator (1), the effect of maintaining the freshness by delaying deodorization and vegetable decay was demonstrated. In addition, a sample of the raw material for the yakiniku 2)
And the ice sample of the ice maker 3) was observed for 10 days, but there was almost no change. Also, when the electrode plates (2) and (3) were touched by mistake, a slight current flowed through the plate, but did not feel strong enough to adversely affect the human body. Furthermore, when placing the electrode plates (2) and (3) on the refrigerator, the compact design saves space and can be installed anywhere, so hold it in your hand and attach it to the inner wall of the refrigerator (1). Just set it easily. When the effect is reduced, the surfaces of the electrode plates (2) and (3) can be wiped cleanly to immediately exhibit the original effect. When the surfaces of the electrode plates (2) and (3) are not clean even after wiping, the electrodes may be replaced. In this case, the electrode plates (2) and (3) may be replaced.
If (3) is peeled off by hand and replaced with a new one, other parts can be used without replacement. In addition, since the embodiment has no moving parts, there is almost no failure, and the electricity bill when a 0.15 mA current of 6 V voltage is applied to the electrode plates (2) and (3) is 6 yen / month. It was confirmed that it was very economical at 9 yen.
