A freezer damper 110 is provided between them.

The refrigerator compartment 102 of each storage compartment of the refrigerator 100 is configured to keep the set temperature at 3 degrees, the vegetable compartment 103 at 5 degrees, and the freezer compartment 104 at -18 degrees. Here, the refrigerator compartment damper 108, the vegetable compartment damper 109, and the freezer compartment damper 110 are controlled to open and close when the cool air cooled by the cooler is sent to each room by a fan in order to maintain the set temperature of each room. ing.

  In addition, the vegetable compartment 103 may be 0 degrees or less due to cooling from the freezer compartment 104 that is in contact with the lower surface −18 degrees. For this reason, a vegetable room heater 111 is provided on the lower surface of the vegetable room 103 as means for keeping the vegetable room 103 at 5 degrees to warm the lower surface of the vegetable room 103.

On the other hand, malachion was reduced by 52% in the Chinese cabbage preserved at an oxygen concentration of 25%, clearly showing a difference in residual pesticide concentration. Moreover, although the browning state of the vegetable surface was compared, the direction of the comparative example 1 was brown. In addition, experiments were also conducted with chloropyrifos and methamidophos, and there was less pesticide residue when stored at an oxygen concentration of 25%.

  The vegetable compartment 103 generates light of 315 nm to 380 nm, that is, ultraviolet rays for decomposing and removing harmful substances such as agricultural chemicals adhering to the surfaces of vegetables and fruits stored in the vegetable compartment 103 by oxidative decomposition. A light source 310 and a pump 212 for controlling the air pressure in the vegetable compartment 103 are provided.

  About the agrochemical degradation promotion means of the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

Light is emitted from a light source 310 installed in the vegetable compartment 103, and light is applied to vegetables and fruits. Light comes into contact with harmful substances such as pesticides adhering to the surface of vegetables and fruits, and these harmful substances are decomposed into harmless safe substances by oxidative decomposition of ultraviolet rays.

  Here, the decomposition and removal by the light emitted from the light source 310 is oxidative decomposition, so that the oxidative decomposition proceeds faster when the intensity of light is as high as possible. As a result, these harmful substances can be decomposed efficiently. Since UV rays have a high concentration, there is a concern about adverse effects on stored foods such as vegetables and fruits. Although any light source can be used as the light source 310, it is preferable to use an LED lamp because it is inexpensive.

Next, the case where the pump 311 is driven will be described. By operating the pump 311, the pressure in the vegetable room can be reduced or increased from the normal pressure of 1 atm, and the activity of the vegetables can be stimulated.
(Experimental example 2)
Apples with a known concentration applied to a vegetable room with different atmospheric pressure were stored for 24 hours, and the change in the concentration of pesticide from the beginning was compared. The operation state of the refrigerator is as in the first embodiment. As the light source, an ultraviolet LED having a center wavelength of 365 nm was used. The output is a 0.6 mW LED. A light source was installed at the top of the vegetable room so that the distance from the light source to the apple was 15 cm. The apple stored in the vegetable room was cut into 4 cm square, and chloropyrifos was applied at 5 ppm by weight. As a comparative example, this was stored for 24 hours in a vegetable room where the pressure at which the pump 311 was not operated was 1 atm. Ten test pieces were used. At the same time, the apples that had been treated in the same manner were stored in a vegetable room where the pressure was reduced to 0.8 atm by operating the pump 311. After 24 hours, the Chinese cabbage was taken out, crushed and extracted with a solvent, and then quantified using a gas chromatograph.

  As a result, in Comparative Example 1, chloropyrifos was reduced by 20% compared to the initial coating amount. In contrast, in apples stored in a vegetable room at 0.8 atm, chloropyrifos decreased by 41%, clearly showing a difference in residual pesticide concentration. Moreover, although the browning state of the vegetable surface was compared, the direction of the comparative example 1 was brown. In addition, experiments were also conducted in malathion and methamidophos, and there was a tendency for the amount of pesticide residue to be reduced when stored in a vegetable room at 0.8 atm, that is, a large decrease compared to the initial stage.

(Embodiment 3)
FIG. 3 is a side sectional view of the refrigerator according to the embodiment of the present invention.

  In FIG. 3, the refrigerator 100 is partitioned into a refrigerator compartment 102, a vegetable compartment 103, and a freezer compartment 104 from above by a partition plate 101.

  Further, in order to cool the refrigerator 101, the refrigeration cycle includes a compressor, a condenser, a decompression device (not shown) such as an expansion valve and a capillary tube, a cooler 105, piping connecting these components, a refrigerant, and the like. The storage room of the refrigerator 101 is cooled by the cold air generated by the refrigeration cycle.

  The refrigerator 101 has a fan 106 for conveying the cold air cooled by the cooler 105 to each storage room space, and a cooling air passage 107 for conveying the cold air blown by the fan 106 to each storage room space. Yes, the air passage 107 is thermally insulated by each storage chamber and the partition plate 101.

  The cooling air passage 107 is provided with a refrigerator compartment damper 108 between the cooler 104 and the refrigerator compartment 102, and the vegetable compartment damper 109, the cooler 104 and the refrigerator compartment between the condenser 104 and the vegetable compartment. A freezer damper 110 is provided between them.

  The refrigerator compartment 102 of each storage compartment of the refrigerator 100 is configured to keep the set temperature at 3 degrees, the vegetable compartment 103 at 5 degrees, and the freezer compartment 104 at -18 degrees. Here, the refrigerator compartment damper 108, the vegetable compartment damper 109, and the freezer compartment damper 110 are controlled to open and close when the cool air cooled by the cooler is sent to each room by a fan in order to maintain the set temperature of each room. ing.

  In addition, the vegetable compartment 103 may be 0 degrees or less due to cooling from the freezer compartment 104 that is in contact with the lower surface −18 degrees. For this reason, a vegetable room heater 111 is provided on the lower surface of the vegetable room 103 as means for keeping the vegetable room 103 at 5 degrees to warm the lower surface of the vegetable room 103.

  Moreover, under the cooler 105, frost adheres to the cooler 105 due to moisture generated from food stored in the refrigerator 100, and a defrost heater 112 is provided for melting the frost. When the defrost heater 112 is in operation, in order to prevent the air heated by the defrost heater 112 from flowing into the refrigerator compartment 102, the vegetable compartment 103, and the freezer compartment 104 and increasing the temperature of each storage compartment, the refrigerator compartment damper 108 and vegetables The chamber damper 109 and the freezer damper 110 are controlled to be closed to prevent a temperature rise.

Further, the vegetable compartment 103 includes a hypochlorous acid aqueous solution generation and supply device 410 for decomposing and removing harmful substances such as agricultural chemicals attached to the surfaces of vegetables and fruits stored in the vegetable compartment 103 by oxidative decomposition. 422 light sources A and 423 light sources B are provided. The hypochlorous acid aqueous solution supply device 410 will be described. When two electrodes are installed in the tap water in the container and a voltage higher than a certain level is applied between the electrodes, electrolysis occurs, and chlorine is generated in addition to oxygen on the anode side. A certain proportion of the chlorine becomes hypochlorous acid and hypochlorite ions having strong oxidizing power in the aqueous solution.
The light source A 422 can emit light having a wavelength of 315 nm to 380 nm, that is, ultraviolet rays, and the light source B 423 can emit light having a wavelength of 780 nm to 1 mm, that is, infrared rays.

  About the agrochemical degradation promotion means of the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, a hypochlorous acid aqueous solution is sprayed from a hypochlorous acid aqueous solution generation and supply device 410 installed in the vegetable compartment 103 to fill the mist in the vegetable compartment 103 in which vegetables and fruits are stored. The filled hypochlorous acid comes into contact with harmful substances such as pesticides adhering to the surface of vegetables and fruits, and these harmful substances cause a chemical reaction between ozone and oxidative degradation, and become safe and harmless substances. Disassembled. Here, the decomposition and removal by hypochlorous acid generated from the hypochlorous acid aqueous solution generation and supply device 410 is oxidative decomposition, so that hypochlorite progresses faster when the concentration of hypochlorous acid is as high as possible. Can be efficiently decomposed, but hypochlorous acid has a negative effect on the human body at high concentrations. Further, when the vegetable compartment 103 is cooled, the cooled cool air is blown and discharged to the vegetable compartment 103 through the cooling sealed passage 107 by the fan 106. For this reason, the hypochlorous acid filled in the vegetable compartment 103 is in an environment in which it is easily diffused from the vegetable compartment 103 due to the air blown at the time of cooling and the cool air of the outflow. Therefore, while the vegetable compartment 103 is being cooled, the hypochlorous acid aqueous solution supply device 410 is stopped. Thereafter, when the cooling to the vegetable compartment 103 is stopped, the hypochlorous acid aqueous solution supply device 410 repeatedly stops the operation and supplies hypochlorous acid to the vegetable compartment 103 again.

Thus, when cold air is flowing into the vegetable compartment 103, the operation is stopped, and when the cold air is not flowing, the hypochlorous acid aqueous solution generating and supplying device 410 is operated, so that the outside of the vegetable compartment 103 Since there is little outflow of hypochlorous acid to the inside of the storage room, a small amount of hypochlorous acid can be used to more reliably store it in the storage room for the purpose of decomposing harmful substances such as residual agricultural chemicals adhering to the surface of vegetables stored in the storage room. Can be filled with chlorous acid.
(Experimental example 3)
The experiment was carried out by storing the boiled vegetables with a known concentration in the vegetable room for 24 hours and comparing the change in the concentration of the agricultural chemical from the initial stage.

  The operating state of the refrigerator is as in Embodiment 1, but the presence or absence of hypochlorous acid generation and the driving states of light sources A and B are as shown in Table 1. The lighting time of the light source A and the light source B was 10 minutes. Bok choy preserved in the vegetable room was cut into 4 cm square leaves, and 5 ppm by weight of methamidophos was applied. Ten test pieces were used in each test. After 24 hours, the Chinese cabbage was taken out, crushed and extracted with a solvent, and then quantified using a gas chromatograph. In addition, the agricultural chemical extraction from vegetables and the analysis method followed the method prescribed | regulated to JIS.

結果を表２に示す、試験１では自然分解により２８％の減少となり、オゾンの存在する試験２ではオゾンの分解効果により、試験１よりは多く減少していた。試験３と試験４は試験２に比べ、青梗菜中の農薬量は減少し、さらに試験４の方がより減少する結果となった。つまり光源Ａと光源Ｂは同時に照射するよりも、交互に照射する方が効果的である結果となった。そのほかにクロロピリホス、マラチオンにおいても実験を行い、同様の順列の傾向がみられた。

The results are shown in Table 2. In Test 1, it was reduced by 28% due to natural decomposition, and in Test 2 where ozone was present, it decreased more than Test 1 due to the decomposition effect of ozone. Compared with Test 2, Test 3 and Test 4 resulted in a decrease in the amount of pesticides in the Chinese cabbage, and Test 4 showed a further decrease. That is, it was effective that the light source A and the light source B were alternately irradiated rather than simultaneously. In addition, experiments were conducted in chloropyrifos and malathion, and similar permutations were observed.

  By alternately irradiating light with wavelengths in the infrared region and light in the ultraviolet region, the vegetables are stimulated and activated, and the ultraviolet rays themselves have high energy and the ability to decompose pesticides. Seems something. However, when irradiation becomes excessive, it seems that it will inhibit the ability of the vegetables themselves to decompose pesticides. Simultaneously irradiating ultraviolet rays and infrared rays is not preferable because of its high inhibitory effect on vegetables and fruits.

  Since the refrigerator according to the present invention can provide more reliable vegetables and fruits to consumers, it can also be applied to storage and commercial refrigerators that store vegetables and fruits at low temperatures.
