By the way, in recent years, various animals and plants have been distributed as meat, vegetables, cooked foods, and ornamental fresh flowers. It is important to maintain quality between the time of arrival and the time of sale, and the time of purchase and consumption.

For example, vegetables change color over time, but when vegetables are cut, the cut ends change color rapidly. Vegetables contain oxidases such as polyphenols, and when the vegetables are cut, the cut end comes into contact with the air and the color changes due to a chemical change. The action of the enzyme drops sharply at low temperatures. Therefore, lettuce, cabbage, apples, peaches, etc., which are easily discolored, are generally kept at a certain temperature or lower in the refrigerator, and consideration is given to keeping the temperature low even when the lettuce, cabbage, apples, peaches, etc. are displayed at the storefront. This also applies to the sale of fresh flowers.

As a method of preventing discoloration, there is also a method of stopping the oxidation itself. Specifically, a substance that prevents oxidation is added to vegetables, and food additives such as hypochlorous acid, baking soda, and trehalose are used. It is often used for business purposes such as cut vegetables for ready-to-eat meals sold at supermarkets. Oxidation of meat also impairs the flavor of the meat when its fat and protein are oxidized, so that antioxidant is an extremely important factor, and it is common practice to add additives.

Maintaining quality for a long time is important not only for business use but also at home. In recent years, the number of so-called single-person households has increased, but due to the increase in overtime hours, many households cannot afford to go shopping every day. Therefore, bulk buying will be done once every few days. Therefore, it is necessary to have an environment in which the quality of the purchased meat and vegetables can be maintained for several days to a week, and in response to this, refrigerators with a dedicated environment such as a meat room and a vegetable room are on the market.

By the way, various effects of hydrogen water have been clarified. Hydrogen water is believed to have a strong antioxidant function. Hydrogen water consists of water and hydrogen and does not contain any additives that may cause side effects on the human body, so it is considered that it can be used as a promising antioxidant.

Furthermore, hydrogen water has the effect of suppressing the solubilization of pectin, which is a polysaccharide that is abundant in fruits, and this can be used to suppress the softening of fruits. In addition, the effect of closing the stomata in the epidermis of the leaves of plants has been clarified. By closing the stomata, the effect of preventing the transpiration of water from the stomata and making the whole plant less likely to wilt can be expected. Regarding the absorption of hydrogen water into plants, there are various channels other than via the canal, and even if the stomata are closed, it is considered that there is no decisive adverse effect on the absorption of hydrogen water into plants. ing. Furthermore, it is considered that hydrogen contained in hydrogen water is easily dissolved in lipids and dissolves in phospholipids constituting biological membranes to suppress deterioration of the membranes due to oxidation of the membranes.

Therefore, various effects can be expected by using hydrogen water to maintain the quality of plants and meat, but when leafy vegetables come into contact with water, the areas where the water adheres tend to hurt. When water adheres to meat, the umami melts and the flavor is impaired. Furthermore, if hydrogen water is kept attached for a long period of time, the tissue may collapse or rot. Therefore, the antioxidant function of hydrogen water could not be used to extend the expiration date of vegetables, fruits, fresh flowers, and meat.

Therefore, in the present invention, a storage device that utilizes hydrogen water and a hydrogen water tank that supplies hydrogen water inside the storage device.
A nebulizer that turns hydrogen water into mist by applying ultrasonic waves,
First closing plate with many holes on one side,
It has a second closing plate, which is characterized by being reticulated.
Provided is a storage device, which is provided with a fan for discharging air from the inside of the storage device to the outside.

The mist-ized hydrogen water spreads throughout the storage device through the holes in the first closing plate, and the density (humidity) around the stored objects such as vegetables, fruits, fresh flowers and meat installed in the second closing plate is always above a certain level. ) To stay. Therefore, the stored object is always affected by hydrogen water, and the time until deterioration such as yellowing starts is postponed.

Further, since the second closing plate has a net shape, water does not collect between the stored object and the plate, and the stored object is not damaged. Furthermore, since the internal air is discharged to the outside by the fan linked with the atomizer, dew condensation due to excessive humidity is prevented.

The storage device 1 is provided with a water tank 2, a hydrogen addition device 3, and a mist conversion device 4 inside.

The water tank 2 is a tank for storing water inside. This water may be ordinary water or hydrogen water which is water containing hydrogen may be adopted. However, hydrogen has a small molecular weight, so it is difficult to seal it. Since hydrogen cannot be retained in resin or wooden tanks, it is desirable to use aluminum for the inner wall when hydrogen water is used.

Most of the fresh flowers, meat, vegetables, and fruits that are considered to be stored in the storage device 1 can be extended in their expiration date by controlling the temperature. Therefore, it is conceivable to give the storage device 1 a cooling function, and as a part of this, it is effective to lower the temperature of the mist itself. Therefore, it is preferable to provide the water tank 2 with a cooling function so that the temperature of the water stored in the water tank 2 is kept below a certain level, preferably 10 ° C. or lower. As a matter of course, any cooling function such as blowing air below room temperature can be adopted as a cooling function.

The hydrogen addition device 3 is a device that changes the water supplied from the water tank 2 into hydrogen-containing hydrogen water by giving hydrogen to the water. As the hydrogen addition means, any known hydrogen generation method can be adopted. As an example, it is conceivable to electrolyze the water supplied from the water tank 2 and adopt the water near the electrode on the side where hydrogen is generated.

Other examples include a method of generating hydrogen by bringing water supplied from the water tank 2 into contact with a catalyst made of silicon, magnesium, lime, etc., or a hydrogen gas supplied from the outside or stored in the hydrogen generator 3. Is a method of dissolving hydrogen gas in water by supplying little by little in the water supplied from the water tank 2 and bubbling, by dissolving the coral contained in the hydrogen gas with the water supplied from the water tank 2. A method of obtaining water containing hydrogen gas can be considered.

The hydrogen addition device 3 adds hydrogen to the water supplied from the water tank 2 by any of the above, a combination thereof, or any known means, and changes the water into hydrogen water. The obtained hydrogen water is supplied to the mist conversion device 4.

The mist-forming device 4 is provided with a small-capacity water tank 41 and an air generator 42 inside, and both are internally connected. Further, the water tank 41 is opened to the outside through a nozzle 43 provided near the tip of the mist-forming device 4. An ultrasonic vibrator 44 is provided on the bottom surface of the water tank 41, and a transmission film 45 is provided inside.

The hydrogen water supplied from the hydrogen generator 3 is temporarily stored in the hydrogen water tank 41. When the mist-forming device 4 starts operating, ultrasonic waves are oscillated from the ultrasonic vibrator 44. This ultrasonic wave is transmitted by the transmission film 45, and the hydrogen water stored in the water tank 41 vibrates. As a result, a liquid column is ejected from the liquid surface of the hydrogen water, and fine hydrogen water mist 46 is generated from the liquid column.

Of the generated mist, the fine particle hydrogen water mist 46 having a mass below a certain level, that is, a size below a certain level, is guided to the outside through the nozzle 43 by the flow of air blown from the air generator 42, and is guided to the outside through the nozzle 43. It is sent out to the inside. Hydrogen water mist having a mass above a certain level cannot reach the outside by the flow of air, and is integrated with the water in the water tank 41 again. As a result, the fine hydrogen water mist 46 discharged to the outside from the nozzle 43 is extremely large. It becomes a fine hydrogen water mist, that is, high quality hydrogen water mist.

The mist-forming device 4 only needs to be able to mist water, and the optimum method thereof is a combination of the above-mentioned ultrasonic vibrator 44 and the transmission film 45, and more specifically, the method described in JP-A-2010-94602. be. The transmission film 45 installed in a state where the ultrasonic waves emitted by the ultrasonic vibrator 44 installed at the bottom of the mist conversion device 4 are inclined from the horizontal by a certain angle to the partition wall installed in the middle of the mist conversion device 4 is hydrogen. It is efficiently transmitted to water 31. It is possible to enjoy a part of the effect of the present invention by using any other known mist-forming means.

The hydrogen addition device 3 and the mist conversion device 4 can be integrated. In that case, a means for imparting hydrogen may be further installed in the hydrogen water tank 41.

The fine particle hydrogen water mist 46 released from the mist conversion device 4 fills the inside of the storage device 1 and comes into contact with vegetables, fruits, fresh flowers, meat and the like stored in the storage device 1. Since the fine particle hydrogen water mist 46 is a very fine water mass, it easily permeates not only the surface of vegetables, fruits, fresh flowers and meat, but also the inside thereof. Therefore, the antioxidant function of hydrogen water works stronger than that of conventional hydrogen water, and it is possible to suppress the influence of deterioration due to oxidation.

Further, since the fine particle hydrogen water mist 46 is a very fine mass of water, the amount of water is insufficient to form a water droplet or a puddle. Therefore, deterioration of vegetables and the like caused by the adhesion of water does not occur.

The fine particle hydrogen water mist 46 is a very fine mass of water, but if the fine particle hydrogen water mist 46 in the storage device 1 exceeds a certain concentration, there is a risk of water droplet formation. Therefore, it is desirable to provide a humidity sensor 47 in the fine particle hydrogen water mist 46 so that the mist formation is interrupted when the concentration exceeds a certain level. Alternatively, an exhaust fan 5 may be provided in the storage device 1 so that the fine particle hydrogen water mist 46 in the storage device 1 is always discharged.

Since the position of the sensor and the position where the vegetables and the like are stored are different, there is a possibility that when the humidity sensor 47 detects excessive humidity, the humidity becomes high around the vegetables and the like and dew condensation starts. The mist-forming device 4 performs an intermittent operation that repeats a cycle of operating for 1 second and then resting for 3 seconds. The humidity sensor 47 monitors the humidity in the storage device 1, and when the humidity is above a certain level, the operation of the mist conversion device 4 is stopped. This is because if the humidity exceeds a certain level, water droplets may be generated in the storage device 1 due to dew condensation or the like and adhere to the stored object. When the humidity is below a certain level, the operation of the mistizing device 4 is restarted. The humidity is measured at the timing when the mist conversion device 4 is stopped, and the humidity is measured in a state where the fine particle hydrogen water mist 46 is sufficiently diffused in the storage device 1. If the temperature of vegetables etc. is lower than the temperature inside the storage device, it is necessary to control it with the open-air temperature. Therefore, a temperature sensor is further built in to measure the temperature of vegetables etc. It may be controlled by temperature.

The exhaust fan 5 is preferably installed above the storage device 1 and has a function of sucking air from the inside of the storage device 1 to the outside. About 1 to 3 intake fans 5 may be installed depending on the size of the storage device 1. The exhaust fan 5 forcibly discharges the fine particle hydrogen water mist 46 together with the internal air to the outside of the storage device 1, so that the total amount of the fine particle hydrogen water mist 46 inside the storage device 1 exceeds the saturation limit, and the vegetables, vegetables, The risk of water droplets adhering to fruits, fresh flowers, meat, and the inside of the storage device 1 is eliminated.

The exhaust fan 5 may have any form as long as it can cause an air flow from the inside to the outside of the storage device 1, including a fan 5 that causes an air flow by rotating a propeller. ..

Depending on the shape of the vegetables or the like, the fine particle hydrogen water mist 46 may locally fill the narrow region sandwiched between the vegetables and the storage device 1 and exceed the saturation limit. In this case, since the saturation limit is exceeded near vegetables and the like, there is a high possibility that the mistized water will become water droplets and adhere to the vegetable surface. In order to prevent this, it is desirable to provide a shelf 6 for stored items in the storage device 1.

The shelf 6 for stored objects is preferably a wire mesh plate made of a wire having a thickness of about 1 mm. The mesh may have a diagonal length of approximately 0.5 mm or more. When vegetables or the like are placed on this wire mesh plate, there is always a sufficient gap between the vegetables and the wire mesh due to the presence of the mesh. Therefore, a certain space or more is always secured between the vegetables and the wire mesh, and the fine particle hydrogen water mist 46 exceeding the saturation limit is not suitable for water.

The storage device 1 of the present invention is filled with the fine particle hydrogen water mist 46 in the entire area inside the storage device 1, particularly around the vegetables, fruits, fresh flowers, meat, etc., which are stored objects, and does not fill the storage device 1 beyond the saturation limit. , It becomes possible to exert the effect. Therefore, it is important that the fine particle hydrogen water mist 46 is equally distributed over the entire area where the stored object may be installed.

However, it is inevitable that there will be a difference in the concentration of the fine particle hydrogen water mist 46 between the periphery of the nozzle 43 and other parts. In particular, when the exhaust fan 5 is provided, an air flow is generated from the periphery of the nozzle 43 to the upper part of the storage device 1 in which the exhaust fan 5 exists, and the peripheral portion of the storage device 1 deviating from the flow is generated. The fine-grained hydrogen water mist 46 almost disappears.

As a countermeasure, it is desirable to provide a mist diffusion plate 7 between the storage shelf 6 and the mist conversion device 4 when the storage shelf 6 exists between the mist conversion device 4 and the non-stored object. The mist diffusion plate 7 is a plate made of resin or glass and having a thickness of about 2 mm, and a large number of holes 71 having a diameter of about 0.1 cm to 2 cm are opened at intervals of a pitch of 5 mm to 1 cm. As a result of repeated experiments by the inventors, when the diameter of the hole 71 exceeds 3 cm, almost all of the mist is removed from the hole 71 directly above the mist-forming device 4, and the mist diffusion effect can hardly be exhibited. all right.

The fine particle hydrogen water mist 46 discharged from the nozzle 43 spreads laterally by being blocked by the mist diffusion plate 7, and gradually passes to the upper part through the holes 71. As a result, the fine particle hydrogen water mist 46 spreads over the entire area of the storage device 1. By inserting another mist diffuser plate 7 having different holes, the fine particle hydrogen water mist 46 can be diffused over the entire area of the storage device 1 without any bias.

Hereinafter, the present invention will be described in a manner more suitable for the embodiment.

Example 1 is a storage device 1 in a normal temperature environment suitable for storing vegetables and fruits. As shown in FIG. 1, the storage device 1 includes a water tank 2, a hydrogen addition device 3 and a mist conversion device 4 integrated therein, an exhaust fan 5, a shelf for stored objects 6, and a mist diffusion plate 7. It has. FIG. 2 is an image diagram of a storage device having the function shown in FIG.

The storage device 1 has a depth of 50 cm, a width of 50 cm, and a height of 80 cm, and is formed in a rectangular parallelepiped shape by a resin plate. A power cord for supplying electricity to the mist-forming device and the like and a switch 11 for turning on / off the electricity supply from the power source are provided on the outside of the storage device 1.

When the switch 11 is turned on with the power cord connected to the power supply, the hydrogen addition device 3, the mist conversion device 4, and the exhaust fan 5 start operating, and when the switch 11 is turned off, these devices stop operating. It also has a timer function, which automatically turns off after a certain period of time.

The water tank 2 can store about 300 ml of water. The water tank 2 is configured to be removable, and when replenishing water, it is removed from the storage device 1.

The device in which the hydrogen addition device 3 and the mist conversion device 4 are integrated is provided with a hydrogen gas storage cylinder 31, a hydrogen water tank 41, an air generator 42, and a nozzle 43 inside the hydrogen water tank 41. Is provided with an ultrasonic transducer 44 and a transmission film 45. The ultrasonic transducer 44 is provided at the bottom of the hydrogen water tank 41, and the transmission film 45 is provided in the middle of the hydrogen tank 41. The ultrasonic transducer 44 receives the ultrasonic waves generated by the ultrasonic transducer 44 and efficiently transmits the ultrasonic waves to the hydrogen water 31. ..

When the switch 11 is turned on, the hydrogen addition device draws water from the water tank 2 by a known method and guides it to the hydrogen water tank 41. When it is detected that the amount of water exceeds a certain amount, the hydrogen gas supplied from the hydrogen gas storage cylinder 31 is then released in the hydrogen water tank 41.

As a result, a part of the hydrogen gas is dissolved in the water to generate hydrogen water 31. The undissolved hydrogen diffuses to the inside and the outside of the storage container 1 without being affected by the presence of the resin due to its small molecular weight.

Ultrasonic waves are generated from the ultrasonic vibrator after about 1 to 3 minutes have passed to generate hydrogen water in which sufficient hydrogen is dissolved. This ultrasonic wave vibrates the hydrogen water 31 through the transmission film 45 installed in the middle of the hydrogen water tank 41, and as a result, a liquid column is generated on the liquid surface of the hydrogen water 31.

At the same time as the ultrasonic vibration is generated, air is supplied from the air generator 42 to the upper part of the hydrogen tank 41. Of the mist generated from the periphery of the liquid column, a water mass having a size and weight equal to or less than a certain level is blown off by air and discharged as fine particle hydrogen water mist 46 from the nozzle 43. A water mass having a certain size and weight is not blown off by the air, stays in the hydrogen water tank 41 as it is, and is finally integrated with the hydrogen water 31.

The fine particle hydrogen water mist 46 discharged from the nozzle 43 diffuses into the inside of the storage device 1. Since the exhaust fan 5 starts operating at the same time as the air generator 42 operates, the storage device 1 moves from the lower part of the storage device 1 where the nozzle 43 is installed to the upper part of the storage device 1 where the exhaust fan 5 is installed. There is an air flow towards it. Along with this flow, the fine particle hydrogen water mist 46 diffuses into the storage device 1.

The mist diffusion plate 7 is composed of two resin plates having a diameter of 3.5 mm and a large number of holes having a diameter of 7 mm at intervals of 7 mm and having a thickness of 2 mm, and the positions of the holes are different between the two plates. It is characterized by. The mist diffusion plate 7 obstructs the flow of air from the lower part to the upper part of the storage device 1, and the air cannot flow to the upper part without passing through a large number of holes 71 formed in the mist diffusion plate 7. In the process, the air flows along the mist diffusion plate 7 in the lateral direction and the depth direction of the storage device 1, and the fine particle hydrogen water mist 46 also diffuses to the entire area of the storage device along this flow. To go.

Vegetables, fruits, fresh flowers, meat and the like stored in the storage device 1 are arranged on the storage shelf 6 provided above the mist diffusion plate 7. When the fine particle hydrogen water mist 46 moves to the uppermost part of the storage device 1 where the exhaust fan 5 exists via the holes 71 and the mesh of the shelf 6 for stored objects, vegetables, fruits, fresh flowers, meat, etc. Contact the items to be stored.

Since the fine hydrogen water mist 46 is a very small water mass or hydrogen gas melted in this water mass, it has a structure that is easily absorbed into the stored object when it comes into contact with the stored object. The fine particle hydrogen water mist 46 absorbed into the inside exerts various effects of hydrogen water on the stored object and exerts a function of delaying the deterioration of the stored object.

The fine particle hydrogen water mist 46 that has not been absorbed is discharged to the outside of the storage device 1 via the exhaust fan 5. The wind force of the exhaust fan 5 is set to a force capable of maintaining a concentration at which the fine particle hydrogen water mist 46 does not stay inside the storage device 1 at a concentration higher than necessary and water droplets do not adhere to the stored object. The force is controlled by the balance with the outputs of the ultrasonic vibrator 44 and the air generator 42.

In the storage device 1 created in Example 1, four slices of cut apples are stored, and as a comparative example, four slices of cut apples are stored in a place where the temperature is the same as the environment in which the storage device 1 exists and is not directly exposed to sunlight 48. Stored for hours. As a result of investigating the degree of discoloration after continuously operating the storage device 1 for 24 hours, the color was substantially the same as that before storage, and no discoloration was observed. On the other hand, all four slices of apples stored indoors turned brown.

The second embodiment is a storage device 1 capable of drawing out the effect of hydrogen water. Hydrogen water is water containing hydrogen, but since hydrogen rapidly diffuses into the atmosphere over time, it is important to constantly supply fresh hydrogen water in order to exert its efficacy. Hereinafter, the points different from those of the first embodiment will be mainly described with reference to FIG.

The shape of the storage device 1 is different from that of the first embodiment, and the bottom surface portion thereof becomes thinner as it approaches the bottom surface, and a hole is opened at the tip thereof. This is because a larger amount of fine particle hydrogen water mist 46 is supplied to the inside of the storage device 1 of the second embodiment, so that dew condensation is likely to occur, and the dew-condensed water is efficiently discharged from the holes on the bottom surface.

The storage device 1 is provided with two mist-forming devices 4, and is installed so as to face the vicinity of both sides of the storage device 1. Therefore, the fine particle hydrogen water mist 46 discharged from the nozzle 43 collides with the vicinity of the center of the storage device 1, causing turbulence, and the fine particle hydrogen water mist 46 is more likely to diffuse over the entire storage device 1 than in the first embodiment.

By setting a large displacement of the exhaust fan 5 installed on the upper part of the storage device 1, the diffusion speed of the fine particle hydrogen water mist 46 in the upward direction of the storage device 1 becomes high, and the unit time of the fine particle hydrogen water mist 46 is increased. Even if the amount of discharged particles per particle increases, the humidity inside the storage device 1 can be kept below a certain level. On the other hand, since it becomes difficult to diffuse in the lateral direction and the depth direction, two mist diffusion plates 7 are provided in order to further enhance the function of the mist diffusion plate 7. By installing the holes 71 of the mist diffusion plate 7 so as to be offset between the two, the diffusion effect is further enhanced.

The storage device 1 of the second embodiment enhances the function of the exhaust fan 5 while increasing the amount of the fine particle hydrogen water mist 46 released, whereby the fine particle hydrogen water mist in a state where the stored object has a higher hydrogen content. It is possible to bring the 46 into contact.

The third embodiment is a storage device 1 having a refrigerating function, and is preferably added as an additional function to the vegetable room and the meat room of a conventional refrigerator. Hereinafter, the points different from those of the first embodiment will be mainly described. As shown in FIG. 4, the storage device 1 includes a device in which a hydrogen addition device 3 and a mist conversion device 4 are integrated, a shelf for stored objects 6, and a temperature control device 8. The temperature control device 8 is a device that provides a function of performing normal temperature control, which is provided in a vegetable room or a meat room of a conventional refrigerator.

In the storage device 1 of the third embodiment, the water tank 2 and the hydrogen are not provided in order to use the refrigerator for a limited space, and the hydrogen addition device 3 and the mist conversion device 4 are integrated. Regarding the replenishment of water, water is directly supplied to the hydrogen water tank 41 from the outside.

A catalytic method is adopted as the hydrogen addition method. When magnesium or silicon powder or the powder is kneaded and held in water, it acts on water molecules to generate hydrogen. Utilizing this property, a catalyst is supported in the hydrogen water tank 41, and the water in the hydrogen water tank 41 is changed to hydrogen water 31 in which hydrogen is dissolved.

The mist-forming device 4 performs an intermittent operation that repeats a cycle of operating for 1 second and then resting for 3 seconds. The humidity sensor 47 monitors the humidity in the storage device 1, and when the humidity is above a certain level, the operation of the mist conversion device 4 is stopped. This is because if the humidity exceeds a certain level, water droplets may be generated in the storage device 1 due to dew condensation or the like and adhere to the stored object. When the humidity is below a certain level, the operation of the mistizing device 4 is restarted. The humidity is measured at the timing when the mist conversion device 4 is stopped, and the humidity is measured in a state where the fine particle hydrogen water mist 46 is sufficiently diffused in the storage device 1.

However, the action of the catalyst is not in time for 5 minutes after the water is supplied, and sufficient hydrogen is not generated. Therefore, regardless of the judgment of the humidity sensor 47, the operation is not started for 5 minutes after the water is supplied to the storage device 1. In order to realize this operation, a sensor that measures the amount of hydrogen may be introduced, but as a pseudo-realization method, even if the storage device 1 is not operated for 5 minutes after opening and closing, almost the same result is obtained. The latter is selected in the storage device 1 of the third embodiment.

The storage device 1 of the third embodiment does not include the exhaust fan 5, and the state in which the internal humidity has risen tends to continue for a certain period of time. Therefore, it is equipped with a dehumidifying mechanism that operates about once every 30 minutes to 1 hour, and is configured to periodically reduce the humidity. When the dehumidifying mechanism is operating, the mistizing device 4 does not operate regardless of the determination of the humidity sensor 47.

The operation of the storage device 1 is the same as that of the first embodiment except that the water tank 2 does not exist and the hydrogen addition method is a catalytic method. That is, when the operation starts, the ultrasonic waves generated by the ultrasonic vibrator 44 vibrate the hydrogen water 31 through the transmission film 45, a liquid column is generated on the surface of the hydrogen water 31, and the air from the air generator 42 is generated. Only water lumps having a certain size and mass or less are discharged to the inside of the storage device 1 as fine hydrogen water mist 46 via the nozzle 43.

The storage device 1 is provided with a temperature control device 8, and it is necessary to keep the internal temperature below a certain level. Therefore, since the mechanism for discharging the internal air to the outside is not adopted, unlike the first embodiment, the air flow from the lower part to the upper part of the storage device 1 is small, but the entire area of the storage device 1 is covered with fine particle hydrogen over time. Water mist 46 diffuses. In the process, the fine hydrogen water mist 46 comes into contact with vegetables, fruits, meat, fresh flowers, etc. arranged on the shelf 6 for stored objects, and various effects of hydrogen water may be exerted on these stored objects. It will be possible.

In order to suppress the action of the enzyme that causes discoloration, it is effective to keep the temperature below a certain level and to utilize both antioxidants, but the storage device 1 of Example 3 is temperature-controlled. Since it has a function and can utilize the antioxidant function of the fine hydrogen water mist 46, it has a very excellent function of preventing discoloration and increasing the expiration date.

In the storage device 1 created in Example 3, 4 slices of cut apples are stored, and as a comparative example, 4 slices of cut apples are stored in a place where the temperature is the same as that of the storage device 1 and is not directly exposed to sunlight 96. Stored for hours. As a result of investigating the degree of discoloration after continuously operating the storage device 1 for 24 hours, the color was substantially the same as that before storage, and no discoloration was observed. On the other hand, all four slices of apples stored indoors turned brown.

Although a catalyst was adopted as the method of hydrogenation, the method of directly supplying hydrogen gas from the hydrogen gas storage cylinder 31 as in the first embodiment and the method of electrolyzing water are also adopted according to the third embodiment. The storage device 1 can be preferably implemented.

Example 4 is a storage device 1 suitable for fresh flowers. Hereinafter, the points different from those of the first embodiment will be mainly described. As shown in FIG. 5, the storage device 1 includes a water tank 2, a hydrogen addition device 3, a mist conversion device 4, a mist diffusion plate 7, and a temperature control device 8 inside.

The storage device 1 has a depth of 120 cm, a width of 180 cm, and a height of 200 cm. One of the four surfaces connecting the bottom surface and the ceiling surface and the bottom surface and the ceiling surface is made of a metal plate, and the remaining three surfaces are made of a glass plate. It is formed in a rectangular parallelepiped shape. A power cord for supplying electricity to the mist-forming device and the like and a switch 11 for turning on / off the electricity supply from the power source are provided on the outside of the storage device 1. A water supply dish 9 is provided at the bottom thereof.

When the switch 11 is turned on with the power cord connected to the power supply, the hydrogen addition device 3, the mist conversion device 4, and the temperature control device 8 start operating, and when the switch 11 is turned off, these devices stop operating.

The water tank 2 can store about 1 liter of water. The water tank 2 is configured to be removable, and when replenishing water, it is removed from the storage device 1.

The hydrogen addition device 3 is provided with a hydrogen gas storage cylinder 31. When the switch 11 is in the ON state, water is taken out from the water tank 2 and the hydrogen gas supplied from the hydrogen gas storage cylinder 31 in the water is released to change the water into hydrogen water 31 and to the mist conversion device 4. Hydrogen water 31 is supplied.

Like vegetables and fruits, fresh flowers accelerate quality deterioration when water droplets adhere to the flowers and leaves. However, for stems, soaking in water has the effect of sucking water from the canal and maintaining the freshness of fresh flowers. This effect is further enhanced by using hydrogen water having a strong antioxidant power. Therefore, hydrogen water 31 is supplied to the water supply dish 9 in addition to the mist conversion device 4, and the stems of fresh flowers are immersed in the water supply dish 9 for storage. The water supply dish 9 is installed on the mist diffusion plate 7.

The mist-forming device 4 includes a hydrogen water tank 41, an air generator 42, and a nozzle 43 inside, and an ultrasonic vibrator 44 and a transmission film 45 inside the hydrogen water tank 41.

When the switch 11 is turned on, the hydrogen water 31 supplied from the hydrogen addition device 3 is stored in the hydrogen water tank 41, and when it is detected that the amount of hydrogen water 31 exceeds a certain amount in the hydrogen water tank 41, it is super. Generates ultrasonic waves from a sound transducer. This ultrasonic wave vibrates the hydrogen water 31 through the transmission film 45 installed in the middle of the hydrogen water tank 41, and as a result, a liquid column is generated on the liquid surface of the hydrogen water 31.

At the same time as the ultrasonic vibration is generated, air is supplied from the air generator 42 to the upper part of the hydrogen tank 41. Of the mist generated from the periphery of the liquid column, a water mass having a size and weight equal to or less than a certain level is blown off by air and discharged as fine particle hydrogen water mist 46 from the nozzle 43. A water mass having a certain size and weight is not blown off by the air, stays in the hydrogen water tank 41 as it is, and is finally integrated with the hydrogen water 31.

The fine particle hydrogen water mist 46 discharged from the nozzle 43 diffuses into the inside of the storage device 1. Since the fine particle hydrogen water mist 46 is a very small water mass or hydrogen gas melted in this water mass, it comes into contact with fresh flowers. It has a structure that is easily absorbed into the inside of fresh flowers. The fine particle hydrogen water mist 46 absorbed into the inside exerts a function of delaying the deterioration of the stored object by the various effects of the hydrogen water acting on the fresh flowers.

The mist-forming device 4 performs an intermittent operation that repeats a cycle of operating for 1 second and then resting for 5 seconds. Since the size of the ikebana storage device 1 is large, it takes a long time to sufficiently diffuse the flower arrangement in the storage device 1, so that the rest time is set long. The humidity sensor 47 monitors the humidity in the storage device 1, and when the humidity is above a certain level, the operation of the mist conversion device 4 is stopped. This is because if the humidity exceeds a certain level, water droplets may be generated in the storage device 1 due to dew condensation or the like and adhere to the stored object. When the humidity is below a certain level, the operation of the mistizing device 4 is restarted. The humidity is measured at the timing when the mist conversion device 4 is stopped, and the humidity is measured in a state where the fine particle hydrogen water mist 46 is sufficiently diffused in the storage device 1.

The mist diffusion plate 7 is composed of four resin plates having a thickness of 2 mm and having a large number of holes having a diameter of 1 cm, and each of the four plates is characterized in that the positions of the holes are different. Although the ikebana storage device 1 is large in size, it is difficult to create an air flow because the exhaust fan 5 cannot be installed. Therefore, by increasing the number of mist diffusion plates 7, a configuration is adopted in which the fine particle hydrogen water mist 46 is easily diffused in the lateral direction.

In order to suppress the action of enzymes that cause deterioration of fresh flowers, it is effective to keep the temperature below a certain level and to utilize both antioxidants. Since it has a temperature control function and can utilize the antioxidant function of the fine particle hydrogen water mist 46, it has an excellent function of extending the product life of fresh flowers.

The storage device 1 of the fifth embodiment is a modification of the fourth embodiment, and is different in that it includes an exhaust fan 5 and a duct. Hereinafter, the points different from those of the fourth embodiment will be mainly described with reference to FIG.

The storage device 1 of the fifth embodiment includes an exhaust fan 5, and an air flow is generated around the object to be stored by using the exhaust fan. Therefore, the humidity of the place where the stored object is stored is unlikely to increase.

The air and fine particle hydrogen water mist 46 discharged from the exhaust fan 5 are not discharged to the outside of the storage device 1, but are guided to the temperature control device 9 via a duct which is an internal structure of the storage device 1. Be taken. The temperature control device 9 has both a temperature control function and a dehumidification function. The inside of the storage device 1 is again in a state where the fine particle hydrogen water mist 46 is removed from the air and cooled to the set temperature. Is released to.

By connecting the exhaust fan 5 and the temperature control device 9 with a duct, the storage device 1 of the fifth embodiment supplies a larger amount of fine particle hydrogen water mist 46 per unit time as compared with the storage device 1 of the fourth embodiment. Even if it does, there is no condensation. Therefore, the effect of hydrogen water can be brought out more strongly.

The storage device 1 of Examples 4 and 5 is mainly most suitable for storing fresh flowers, but it can also be used for storing vegetables and fruits when the water supply dish 9 is removed.

The storage device 1 of the sixth embodiment is a modification of the fourth and fifth embodiments, and the water tank 2, the hydrogen addition device 3, and the mist conversion device 4 of the storage device 1 of the fourth and fifth embodiments are placed inside the transportation container. It was installed. Hereinafter, the points different from those of Examples 4 and 5 will be mainly described.

Since it is possible to fill the inside of the transportation container with the fine particle hydrogen water mist 46, it is possible to deliver the fresh flowers to the destination in a fresher state. It may be installed inside a low temperature container having a temperature control function.

Since fresh flowers and vegetables are prone to deterioration and the product life is short, it was necessary to use air mail when importing from overseas and high-cost truck mail for domestic transportation, but the storage device of the present invention. If it is 1, the antioxidant function of the fine hydrogen water mist 46 significantly stagnates the action of the enzyme, so that even if the transportation time increases, it is possible to deliver to the destination with the same quality as before. Yes, sea mail and rail mail will be available.

Further, since hydrogen gas volatilizes in the fine particle hydrogen water mist 46 with time, there is no side effect. Therefore, it can be safely used for very sensitive shipments such as vegetables, fruits, and meat that enter the human mouth.

The storage device 1 according to the seventh embodiment is a portable type of the storage device 1 according to the first embodiment, and is used in an open space instead of filling the closed space in the storage device 1 with the fine particle hydrogen water mist 46. , Used to exert an antioxidant function on an object near the mist-forming device 4. Hereinafter, the points different from those of the first embodiment will be mainly described.

As shown in FIG. 7, the mist-forming device 4 includes a hydrogen gas storage cylinder 31, a hydrogen water tank 41, an air generator 42, and a nozzle 43, and an ultrasonic transducer is provided in the hydrogen water tank 41. 44, a transmission film 45 is provided.

The mist conversion device 4 of the seventh embodiment does not include the water tank 2 in order to improve portability, and the hydrogen addition device 3 and the mist conversion device 4 are integrated. Regarding the replenishment of water, water is directly supplied to the hydrogen water tank 41 from the outside.

When the switch 11 is turned on, the mist conversion device 4 starts operation, and the fine particle hydrogen water mist 46 is discharged from the nozzle 43 as in the first embodiment. The fine hydrogen water mist 46 diffuses from the periphery of the nozzle 46 to the entire open space, and in the process, the fine hydrogen water mist 46 comes into close contact with the object near the nozzle 46, and the fine hydrogen water mist 46 has. Various effects of hydrogen water can be applied. A suitable target is a flower that grows in a sword mountain or a vase, and by operating it near it, the cut flower can last a long time.

As the method of adding hydrogen, a method of releasing the hydrogen gas supplied from the hydrogen gas storage cylinder 31 in the hydrogen tank 41 is adopted, but a catalytic method or an electrolysis method may also be used. In particular, in the case of the catalytic method, the amount of hydrogen generated is inferior, but there is an advantage that it is easy to miniaturize.
