Description

  The present invention relates to a container capable of retaining and cooling a storage object.

  In general refrigeration equipment, it is difficult to maintain the humidity of the refrigerated space at the same level as before cooling. This is because moisture in the air is removed by condensing moisture on the low temperature surface for cooling the air. Here, when fresh food or the like is refrigerated at low humidity, moisture in the food may be lost and quality may be impaired, and equipment that can be refrigerated while maintaining humidity is required.

  For example, Patent Document 1 describes a high-humidity cool box that humidifies and cools the inside of the box. The high-humidity cool box has a circulation unit, a cooling unit, and a humidifying unit arranged in a sealed container. The air in the sealed container is circulated by the circulation means, cooled by the cooling means, and humidified by the humidification means. The humidifying means humidifies by spraying water on the circulating air.

JP 2006-31729 A (paragraph [0032], FIG. 1)

  However, the high-humidity cool box described in Patent Document 1 requires a power for spraying water throughout the operation, and there is a problem that the operation cost is high. In particular, even when the number of objects to be stored is small, the entire sealed container is humidified, so that useless power is consumed.

  In view of the circumstances as described above, an object of the present invention is to provide a container for moisturizing and keeping cold that does not require the cost for moisturizing.

In order to achieve the above object, a container according to an embodiment of the present invention is a container that keeps an object to be kept moisturized by being placed in a space cooled to a predetermined temperature, and includes a container body, a lid, It comprises.
The container body is made of metal and has a bottom wall, a side wall that surrounds the bottom wall and forms an internal space, and a partition that defines the internal space, so that the container body is higher than before cooling when cooled at the predetermined temperature. A shelf connected to the side wall, which forms a space for accommodating the object to be stored, which is humidity.
The lid is made of metal and is hermetically attached to the side wall, thereby sealing the internal space.

In order to achieve the above object, a container according to an embodiment of the present invention stores an object to be stored in an internal space of the container.
A space for maintaining the water retention amount of the object to be stored during cooling at a predetermined temperature is formed by installing a shelf in the internal space.
The space is made to have a higher humidity than before cooling by cooling the container to the predetermined temperature.

It is sectional drawing which shows the container which concerns on 1st Embodiment. It is a perspective view which shows the 1st accommodation tray which concerns on the same embodiment. It is sectional drawing which shows the container which concerns on 2nd Embodiment. It is a perspective view which shows the 1st accommodation tray which concerns on the same embodiment. It is a perspective view which shows the container which concerns on 3rd embodiment.

A container according to an embodiment of the present invention is a container that keeps an object to be kept moisturized by being placed in a space cooled to a predetermined temperature, and includes a container body and a lid.
The container body is made of metal and has a bottom wall, a side wall that surrounds the bottom wall and forms an internal space, and a partition that defines the internal space, so that the container body is higher than before cooling when cooled at the predetermined temperature. A shelf connected to the side wall, which forms a space for accommodating the object to be stored, which is humidity.
The lid is made of metal and is hermetically attached to the side wall, thereby sealing the internal space.

  An object to be accommodated is accommodated in the space portion of the container main body, and the internal space is sealed by attaching the lid to the side wall in an airtight manner. When the container is placed in a space cooled to a predetermined temperature, it is cooled by cold air, and the air in the internal space is further cooled to a predetermined temperature by the cooled container, thereby cooling the object to be stored. Here, since the shelf connected to the side wall is also cooled by heat conduction from the side wall, the space portion is quickly cooled. Immediately after the cooling is started, the internal space is the atmosphere when the object to be accommodated is accommodated. As the internal space is cooled, the amount of saturated water vapor in the internal space is reduced and the humidity is higher than before cooling, so that the water vapor is absorbed by the accommodation object and the accommodation object is moisturized. When the initial atmosphere is low humidity or the object to be stored contains a large amount of moisture, the moisture is temporarily released from the object to be stored into the internal space. Since the internal space is partitioned into a plurality of space portions by shelves, the released moisture remains in each space portion. Due to the increase in humidity accompanying cooling, the released moisture is again absorbed by the accommodation object, and the accommodation object is moisturized.

The container body includes a first storage wall having a first bottom wall portion constituting the bottom wall, a first side wall portion constituting a part of the side wall, and a second constituting the shelf. A second storage tray having a bottom wall and a second side wall connected to the second bottom wall and constituting another part of the side wall; the first side wall; and the second side And a sealing member disposed between the side wall portions of the first and second side walls.
By accommodating and stacking the objects to be stored in the first and second storage trays, it is possible to form a container body in which the objects to be stored are stored. When the volume of the internal space is excessive with respect to the amount of the object to be stored, moisture released from the object to be stored diffuses into the internal space when the temperature of the internal space at the start of cooling is high. There may be no humidity. Since the container main body is configured by stacking the first storage tray and the second storage tray, the number of the storage trays, that is, the volume of the internal space is adjusted according to the amount of objects to be stored. Is possible. Thereby, even if it is a case where there are few accommodation objects, the humidity of internal space is maintained at a higher humidity than before cooling, and an accommodation object is moisturized.

The said container main body may have a water | moisture-content supply part for supplying the water | moisture content for moisture retention to the said internal space, and the channel | path for making the said space part connect individually.
There may be a shortage of moisture for retaining the object to be stored, such as when the initial atmosphere is low humidity or the amount of water contained in the object to be stored is small. Moisture is supplied to the internal space by the water supply unit, and the moisture is communicated to each space by the passage, whereby the humidity of the internal space is maintained and the object to be stored is moisturized.

The passage may be a through hole formed in the shelf.
According to this structure, the water | moisture content supplied by the water | moisture-content supply part is connected to each space part through the through-hole formed in the shelf.

The accommodation object is a farm product, and the container body may have an absorber for absorbing ethylene released from the farm product.
When the object to be stored is a crop, ethylene crops or the like (hereinafter referred to as ethylene), which are plant growth hormones, are released from the crop and stay in the internal space, so that the crop may mature or rot. Ethylene released from the object to be stored is absorbed by the ethylene absorber disposed in the internal space, and the decay or ripening of the crop is suppressed.

The said shelf forms the said space part in the magnitude | size which can maintain the water retention amount of the said accommodation target object at the time of the said predetermined temperature cooling.
The inner space is partitioned by the shelf, and a plurality of space portions having a small volume are formed. Thereby, it is prevented that the water | moisture content discharge | released from an accommodation target object in the state where the temperature of the internal space at the time of a cooling start is high spread | diffuses to an internal space, and an accommodation object is moisturized.

The object to be stored is a crop, and the internal space has a storage space for storing the crop, and an ethylene decomposition space for decomposing ethylene released from the crop, and the container has the ethylene decomposition You may further comprise the ethylene decomposition apparatus arrange | positioned in space, and the circulation part which circulates the gas in the said internal space between the said storage space and the said ethylene decomposition space.
Plant growth hormone (ethylene gas or the like, hereinafter referred to as ethylene) released from agricultural products is carried to the ethylene decomposition space by the circulation part and decomposed by an ethylene decomposition apparatus provided in the ethylene decomposition space. Thereby, it becomes possible to suppress the decay or ripening of crops by ethylene.

The ethylene decomposition apparatus is an ozone generator that generates ozone in the ethylene decomposition space or an ultraviolet radiation source that radiates ultraviolet light into the ethylene decomposition space, and the container is sent from the ethylene decomposition space to the accommodation space. You may further comprise the ozone removal part which removes ozone from the gas to be performed.
According to this configuration, ethylene is decomposed by ozone generated from an ozone generator or ultraviolet rays emitted from an ultraviolet radiation source. Furthermore, when the ethylene decomposing apparatus is an ultraviolet radiation source, ethylene is also decomposed by ozone generated by the ultraviolet rays. However, when ozone comes into contact with the object to be stored in the storage space, there may be an effect that the object to be stored is decolorized or oxidized. According to the said structure, since ozone is removed from the gas sent to an accommodation space from ethylene decomposition space by an ozone removal part, it is prevented that an accommodation target is influenced by ozone.

The moisturizing and cooling method according to an embodiment of the present invention accommodates an object to be accommodated in an internal space of a container.
A space for maintaining the water retention amount of the object to be stored during cooling at a predetermined temperature is formed by installing a shelf in the internal space.
The space is made to have a higher humidity than before cooling by cooling the container to the predetermined temperature.
An object to be stored is stored in the internal space of the container body, and a shelf is formed in the internal space to form a space portion. By cooling the container to a predetermined temperature, the amount of saturated water vapor in the air in the internal space is reduced, and the humidity in the space becomes higher than before cooling, so that the object to be stored is moisturized.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
A first embodiment will be described.
FIG. 1 is a cross-sectional view showing a container 1 according to the first embodiment of the present invention.
As shown in the figure, the container 1 is disposed in the refrigerator F, and the container 1 accommodates the accommodation object S. The refrigerator F is maintained at 5 ° C., for example. In the present embodiment, the accommodation object S is a crop.

  The container 1 has a container body 2, a lid 3 and a support base 4. The support base 4 is placed on the floor of the refrigerator F. The container body 2 is placed on the support 4 and the lid 3 is attached to the container body 2. The container body 2, the lid 3, and the support base 4 are made of a metal having high thermal conductivity such as aluminum.

  As shown in FIG. 1, the container body 2 includes a bottom wall 5, a side wall 6, and a shelf 7. The bottom wall 5 and the side wall 6 surround the side surface and the bottom surface, and form an internal space that is a space in which the top surface is open. The internal space is partitioned by the shelf 7, and a plurality of space portions R are formed.

  The container body 2 includes a first storage tray 11, a second storage tray 12, a third storage tray 13, a fourth storage tray 14, a fifth storage tray 15, a sixth storage tray 16, and a seventh storage tray. The storage tray 17 and the eighth storage tray 18 are stacked in this order from the bottom. A seal member 20 for maintaining airtightness is disposed between the storage trays.

  Although details will be described later, the bottom wall 5 of the container main body 2 is configured by the first bottom wall portion 11a of the first storage tray 11, and the bottom wall portions of the second to eighth storage trays 12 to 18 respectively. A shelf 7 is configured. Moreover, the side wall 6 of the container main body 2 is comprised by each side wall part of the 1st-8th accommodation trays 11-18.

FIG. 2 is a perspective view showing the configuration of the first storage tray 11.
As shown in the figure, the first storage tray 11 has a first bottom wall portion 11a and a first side wall portion 11b. The first side wall portion 11b is erected on the periphery of the first bottom wall portion 11a. Although the 1st bottom wall part 11a is assumed to be square, it is not restricted to this, A circle etc. may be sufficient. A groove 11c into which the seal member 20 is fitted is formed in the first side wall portion 11b. The first bottom wall portion 11 a constitutes the bottom wall 5 of the container main body 2, and the first side wall portion 11 b constitutes a part of the side wall 6 of the container main body 2.

  Each of the second to eighth accommodation trays 12 to 18 has the same configuration as that of the first accommodation tray 11. That is, the second to eighth storage trays have second to eighth bottom wall portions 12a to 18a and second to eighth side wall portions 12b to 18b, respectively. The second to eighth bottom wall portions 12 a to 18 a constitute the shelf 7 of the container main body 2, and the second to eighth side wall portions 12 b to 18 b constitute a part of the side wall 6 of the container main body 2.

  The first to eighth storage trays are preferably sized so that the volume is as small as possible according to the size of the storage object S. For example, as shown in FIG. 1, when the size of the accommodation object S is uniform and is planned to be accommodated in two upper and lower stages, the first to eighth side wall portions 11b to 18b. The excess volume can be minimized by setting the height of the storage object S to about twice the height of the accommodation object S.

  The lid 3 is attached to the side wall 6 in an airtight manner, thereby sealing an internal space formed by the bottom wall 5 and the side wall 6. The lid 3 is attached to the uppermost stage of the storage tray, that is, the eighth storage tray 18 via a seal member 20.

  The support 4 is cooled by the air in the refrigerator F, thereby preventing heat transfer between the floor of the refrigerator F and the container body 2. The support table 4 may not be provided when the floor of the refrigerator F is sufficiently low in temperature.

  An ethylene absorbent sheet 22 is laid around the accommodation object S in each space R. The ethylene absorbent sheet 22 absorbs ethylene released from the accommodation object S. The ethylene absorption sheet 22 is a sheet containing, for example, zeolite or calcium carbonate. In the present embodiment, the ethylene absorbent sheet 22 corresponds to an absorber.

  A moisturizing and cooling method using the container 1 configured as described above will be described.

  When the accommodation object S is accommodated in the container 1, the first accommodation tray 11 is placed on the support 4 and the accommodation object S is accommodated in the first accommodation tray. Next, the seal member 20 is fitted into the groove 11 c and the second storage tray 12 is stacked on the first storage tray 11. Note that the seal member 20 may be assembled in the groove 11c from the beginning. Next, the objects to be stored are stored in the second storage tray 12 and stacked on the first storage tray 11. Hereinafter, the accommodation object S is accommodated while the third to eighth accommodation trays 13 to 18 are stacked via the seal member 20. Note that the number of storage trays to be stacked may be adjusted according to the amount of the storage object S. Finally, the lid 3 is attached to the uppermost storage tray.

  Due to the weights of the second to eighth accommodation trays 12 to 18 and the lid 3, the seal member 20 provided in each part is elastically deformed, and each space R is sealed. In addition, this accommodation operation may be performed inside the refrigerator F, or after being performed outside the refrigerator F, the container 1 may be carried into the refrigerator F. The refrigerator F may be maintained at a low temperature before the container 1 is assembled or carried in, and cooling may be started after the container 1 is assembled or carried in. A plurality of containers 1 may be arranged in one refrigerator F.

  As described above, the internal space is sealed in a state where the accommodation object S is accommodated. The container 1 is cooled by the low-temperature air in the refrigerator F, and the air in the internal space is cooled by the cooled container 1. Here, since the shelf 7 that partitions the internal space is also cooled by heat conduction from the side wall 6, the internal space is quickly cooled.

  Immediately after the cooling is started, the internal space is an atmosphere (hereinafter referred to as an initial atmosphere) when the accommodation object S is accommodated. As the internal space is cooled, the amount of saturated water vapor in the internal space decreases and the humidity (relative humidity) increases, so that the water vapor is absorbed by the accommodation object S and the accommodation object is moisturized. In addition, when the initial atmosphere is relatively low humidity or the accommodation target S contains a large amount of moisture, moisture is temporarily released from the accommodation target S into the internal space. Here, since the internal space is partitioned into a plurality of space portions R by the shelf 7, the released moisture remains in each space portion R. Due to the increase in humidity accompanying cooling, the released moisture is again absorbed by the accommodation object S, and the accommodation object is moisturized.

  When the volume of the internal space is excessive with respect to the amount of the object to be stored S, the moisture released from the object to be stored S diffuses into the internal space, and the humidity may not be sufficient. Since the container body 2 is composed of the stacked first to eighth storage trays 11 to 18, the number of storage trays, that is, the volume of the internal space is adjusted according to the amount of the storage object S. Is possible. Thereby, even if it is a case where the quantity of the accommodation target S is small, the humidity of internal space is maintained and the accommodation target S is moisturized.

  Moreover, the container main body 2 which concerns on this embodiment has the ethylene absorption sheet 22 accommodated in each space part R. As shown in FIG. Since the accommodation object S is an agricultural product, ethylene, which is a growth hormone released when the plant matures, is released and stays in the space R, so that the agricultural product may mature or decay. By disposing the ethylene absorbent sheet 22 in the space R, it is possible to absorb the released ethylene and suppress the decay or ripening of the crops.

As shown in the figure, the first storage tray 111 has a first bottom wall portion 111a and a first side wall portion 111b. The first side wall 111b is erected on the periphery of the first bottom wall 111a. The first bottom wall portion 111a is assumed to be square, but is not limited thereto, and may be circular or the like. A through hole 111d is formed in the first bottom wall portion 111a. The shape and number of the through holes 111d can be changed as appropriate. A groove 111c into which the seal member 20 is fitted is formed in the first side wall 111b. The first bottom wall portion 111 a constitutes the bottom wall 105 of the container main body 102, and the first side wall portion 111 b constitutes a part of the side wall 106 of the container main body 102.

The circulation part 232 is hermetically connected by a flange or the like at each part. The fan 233 blows the gas in the circulation unit 232 from the pipe 203a side to the pipe 201c side. As a result, an air flow is generated from the fan 233 through the pipe 210c to the container body 202 and from the pipe 203a through the pipe 234 to the fan 233. FIG. 5 shows this air flow by arrows.

  In the vicinity of the ethylene decomposition space T, the airflow passes from the accommodation space through the first ozone removing body 231a and flows into the ethylene decomposition space T. Since the gas shielding plate 203b is provided at the opening of the pipe 203a, the airflow is prevented from flowing into the pipe 203a from the vicinity of the pipe 203a, and the UV lamp is irradiated with ultraviolet rays or mixed with ozone generated from an ozone generator. After being received to some extent, it flows into the pipe 203a.

  A moisturizing and cooling method using the container 200 configured as described above will be described.

  Similarly to the container 1 according to the first embodiment, the accommodation object S is accommodated and the accommodation trays are stacked. After the lids 203 are stacked, the circulation unit 232 is connected in an airtight manner. The power of the fan 233 and the ethylene decomposition apparatus 230 is turned on, and the container 200 is cooled by the low-temperature air in the refrigerator F, and the accommodation object S is moisturized, similarly to the container 100 according to the second embodiment.

  Here, since the airflow is generated by the fan 233 as described above, the ethylene released from the accommodation object S flows into the ethylene decomposition space T by the airflow, and is decomposed and removed by ozone or ultraviolet rays from the ethylene decomposition apparatus 230. Is done. In addition, oxygen in the air is irradiated with ultraviolet rays to generate ozone, and ethylene is also decomposed by this ozone. On the other hand, when ozone contacts the accommodation object S, the accommodation object S is decolorized and oxidized, but the ozone is removed by the first ozone removal body 231a and the second ozone removal body 231b, and the accommodation object S. The influence on is prevented. This is because radicals generated by ozone decomposition transition from the excited state to the ground state on the surfaces of the ozone removing body 231a and the ozone removing body 231b.

  As described above, in the container 200 according to the present embodiment, the accommodation object S is moisturized, and ethylene released from the accommodation object S is decomposed, so that the accommodation object S is prevented from being spoiled or aged. Is possible.

  The present invention is not limited only to the above-described embodiment, and can be changed within a range not departing from the gist of the present invention.

  In each embodiment, the accommodation object is a farm product, but is not limited thereto. What needs moisture retention, such as fresh fish, can be used as the accommodation object.

  In each embodiment, the height of the side wall portion of each storage tray may not be the same. It can be changed according to the size of the accommodation object S.

  In the second embodiment, each accommodation tray is formed with a through hole as a passage for individually communicating the internal space, but is not limited to the through hole. For example, the passage may be a vent provided in the side wall of each storage tray.

  In the second embodiment, a fan or the like for circulating the gas in the internal space may be provided in the internal space. By circulating the gas in the internal space, it becomes possible to circulate water vapor and ethylene supplied to the internal space by the water supply means.

  In each embodiment, the container main body is configured by stacking the first to eighth accommodation trays, but is not limited thereto. For example, the container body can be configured by providing a detachable shelf on one storage tray. In the storage tray, the storage object is stored in a state where the shelf is removed, and after the shelf is attached, the storage object is stored again on the shelf.
