Description

Containment and temperature control system

The present invention relates to a container and a temperature control system.

For example, foods such as seafood, fruits and vegetables (vegetables and fruits), meat, etc. need to be kept fresh for a relatively long period of time, from collection to distribution, store display, etc., even though the freshness tends to drop. In addition, such foods are favored by customers as having higher freshness. Therefore, it is necessary to display the foods in the store while keeping the freshness.

Conventionally, attempts have been made to maintain the freshness of food by freezing or refrigeration of the food using a freezer or the like (see, for example, Patent Document 1). However, when the food is frozen, there is a problem that the cell membrane of the food is destroyed and the taste of the food is lowered. In addition, because temperature control is performed by turning on / off the compressor power supply and controlling the inverter for freezers, refrigerators, etc., there is a large temperature error range and temperature difference in each part of the refrigerator, making it impossible to perform precise temperature adjustment. was there. For this reason, when adjusting to the temperature which does not freeze, temperature may become high and it was difficult to maintain sufficient freshness. In addition, depending on the location and method of food installation, the temperature in each part of the refrigerator is often uneven, and there is a problem that places where the temperature is much higher or lower than the set temperature are created. It was.

In particular, when transporting food while cooling in a refrigerator installed on a truck bed, or when transporting food while cooling in a container with a cooling system loaded on a ship, the arrangement of food in the warehouse, etc. Depending on the case, there is a problem that the cold air is not uniformly transmitted to the inside of the cabinet, and the inside of the cabinet is unevenly cooled. Furthermore, in summer, places where cold air does not reach may reach 20 ° C. or higher, causing food damage.

The container of the present invention can be used as, for example, a stationary container that is installed indoors, such as a food processing factory or a storage, or a mobile type that can be loaded on a moving body such as a ship, an airplane, a train, or an automobile Although it can be used as a storage (for example, a container), it is particularly suitable to be used as the latter mobile storage (for example, the automobile 10 shown in FIG. 1). The mobile storage has a very large temperature adjustment function that affects the external environment (temperature, weather, shade / hinata), and so on. For example, when the temperature is high in summer or when passing through the equator, It was very difficult to keep the inside of the container in a predetermined temperature range. In addition, depending on the amount and arrangement of the luggage loaded in the warehouse, circulation of cold air / hot air is hindered, and it is difficult to adjust the temperature uniformly throughout the warehouse. On the other hand, according to the storage of the present invention, the inside of the storage can be kept in a predetermined temperature range without being substantially affected by the external environment or the situation inside the storage. In this respect, it can be said that the storage of the present invention is particularly suitable for a mobile storage.

The target object stored in the storage of the present invention is not particularly limited, and examples thereof include foods, fresh flowers (including seeds, bulbs, etc.), seedlings, trees, pharmaceuticals (drugs, blood, etc.). In addition, the target may be an animal such as a human, a dog, a cat, a cow, a pig, or a horse (regardless of a living body or a dead body). In addition, the food is not particularly limited, for example, processed foods such as fish, shrimp, squid, octopus, sea cucumber, shellfish and other seafood and their fillets, fruits such as strawberries, apples, tangerines, pears, cabbage, Examples include fresh foods such as vegetables such as lettuce, cucumber and tomatoes, meat such as beef, pork, chicken and horse meat, and noodles made from cereal flour such as wheat flour, rice flour and oat flour. In the following, fruits and vegetables are also referred to as fruits and vegetables.

Hereinafter, preferred embodiments of the container and the temperature adjustment system of the present invention will be described in detail with reference to the accompanying drawings. In the following, for convenience of explanation, the case where the object to be stored in the storage is food and the food is further stored in a cold state will be described as a representative.

FIG. 9 is a side view for explaining an example of control by the control unit shown in FIG. In the following description, the upper side in FIG. 1 is also referred to as “upper” and the lower side is also referred to as “lower”. In order to facilitate the correspondence between the drawings, three axes (X axis, Y axis, Z axis) orthogonal to each other are shown.

The automobile 10 shown in FIG. 1 has a storage 1 arranged on a loading platform. As shown in FIG. 2, the container 1 has a main body 2 having an outer wall 21 and an inner wall 22 made of, for example, aluminum or stainless steel, and a heat insulating material 23 filled between the outer wall 21 and the inner wall 22. is doing. However, the configuration (material and shape) of the main body 2 is not limited to this. The main body 2 is provided with a door (not shown). By opening and closing the door, the food can be stored in the main body 2 and the food in the main body 2 can be taken out. The installation location of the door is not particularly limited. For example, the door may be provided on the side wall of the main body 2, may be provided on the ceiling, or may be provided on the floor. Moreover, as a structure of a door, if food can be taken in and out, it will not specifically limit, For example, a hinge door, a slide door, a shutter door, etc. can be used.

A box-shaped top plate 26 is arranged on the ceiling in the main body 2, and the inside of the main body 2 is partitioned into a space inside the top plate 26 and a space outside. And the space inside the top plate 26 functions as a guide path S1 for guiding air from the temperature adjusting unit 3 described later, and the outer space functions as a storage chamber S2 for storing (storing) food. The configuration of the top plate 26 is not particularly limited as long as the guide path S1 and the accommodation room S2 can be partitioned. Further, the capacity of the storage room S2 is not particularly limited, but for example, a relatively large capacity of about 150 m ³ to 1000 m ³ is suitable.

Moreover, the storage 1 has a machine room R arranged outside the main body 2, and a temperature adjusting unit 3 for adjusting the temperature in the storage room S 2 is provided in the machine room R. Yes. The temperature adjusting unit 3 is not particularly limited as long as the temperature in the storage chamber S2 can be lowered and raised, and for example, a known heat pump can be used.

Further, on the wall at the boundary between the machine room R and the main body 2, the intake port 28 that takes in the air in the storage chamber S 2 toward the temperature adjustment unit 3 and the air cooled by the temperature adjustment unit 3 (hereinafter “cold air”). Is also provided with a blowout port 29 through which the air is blown into the guiding path S1. The intake port 28 and the blowout port 29 are respectively provided with fans (not shown) so that the intake and the blowout can be performed smoothly.

Moreover, the top plate 26 is provided with a plurality of air blowing units 4. The air blowing unit 4 is configured by a fan, and has a function of sending the cold air supplied from the temperature adjusting unit 3 into the guide path S1 through the blowout port 29 to the housing chamber S2. However, the configuration of the blower 4 is not limited to a fan as long as it can send cool air to the storage chamber S2, and for example, an injection nozzle or the like may be used. Although not adopted in the present embodiment, the air outlet 29 of each temperature adjusting unit 3 and each air blowing are provided in the guide path S1 so that the cold air blown out by the temperature adjusting unit 3 is evenly guided to each air blowing unit 4. A plurality of ducts connecting the portion 4 may be arranged.

On the other hand, the floor of the main body 2 is provided with a duct 6 that takes in the air in the storage chamber S2 and guides it to the temperature adjusting unit 3. By providing the duct 6, as shown by the arrow in FIG. 1, the air in the storage chamber S2 can be circulated, and the storage chamber S2 can be efficiently cooled.

Next, the blower unit 4 will be described in detail. As shown in FIG. 3, the plurality of air blowing units 4 provided on the top plate 26 include a first air blowing unit 41 and a second air blowing unit 42. In FIG. 3, for convenience of explanation, the first blower unit 41 is shown in a circle, and the second blower unit 42 is shown in a square.

As shown in FIG. 4, the 1st ventilation part 41 was comprised so that cold air | gas C1 might be sent out toward the floor surface of storage chamber S2, ie, a substantially vertical direction (the height direction of the storage 1) downward. I am a fan. On the other hand, the 2nd ventilation part 42 is a fan (for example, centrifugal fan) comprised so that cold air C2 might be sent out toward a substantially horizontal direction (direction orthogonal to the said height direction).

The 2nd ventilation part 42 is located below the 1st ventilation part 41, and the cold air C2 ventilated from the 2nd ventilation part 42 collides with the cold air C1 ventilated from the 1st ventilation part 41. ing. Thereby, the nonuniformity of the cooling air in the storage room S2 is reduced, and the inside of the storage room S2 can be cooled more uniformly. On the contrary, the cool air C1 blown from the first blower 41 by the cool air C2 can be guided to a predetermined location, and the predetermined location can be preferentially cooled. Here, the second blower 42 not only blows the cool air C2 toward the cool air C1 blown from the first blower 41, but also the cool air blown from the first blower 41 under predetermined conditions. You may drive so that C1 may be attracted | sucked. Moreover, the 2nd ventilation part 42 has the "swing mechanism" used also for a general air blower, for example, and the ventilation direction may be changeable. Thereby, it becomes easier to preferentially cool the predetermined part as described above.

Moreover, as shown in FIG. 3, the 1st ventilation part 41 and the 2nd ventilation part 42 each spread over the whole region of storage chamber S2 by the planar view seen from the perpendicular direction, and are arrange | positioned substantially uniformly. Although it does not specifically limit as arrangement | positioning of the 1st ventilation part 41 and the 2nd ventilation part 42, In this embodiment, the 1st ventilation part 41 is arrange | positioned in matrix form, and the 2nd ventilation part 42 is arrange | positioned among these. Yes. In the present embodiment, eight first air blowing parts 41 and three second air blowing parts 42 are arranged, but the number of first and second

air blowing parts

41 and 42 is not limited to this, It can be set as appropriate in consideration of the size of the storage chamber S2, the power of the first and

second blower portions

41 and 42, the cost, and the like.

In addition, the arrangement density of the first air blowing units 41 is not particularly limited, and may vary depending on the size and power of the first air blowing units 41, for example, about 250 cm ² to 1 m ² / piece in plan view. Is preferred. Further, the flow rate of the cool air sent out by the first blower unit 41 is not particularly limited, but for example, it is preferably about 0.01 to 2.0 m / second immediately below the first blower unit 41. More preferably, it is about 1 to 0.5 m / sec. By setting the flow rate to this level, the storage chamber S2 can be sufficiently cooled and the flow of cold air can be made gentle. As the maximum air volume of the first blower 41 is not particularly limited, for ^example, it is preferably 4.0m ³ /min~5.0m 3 / min approximately. By using such an air volume, it is theoretically possible to move the air up to 5 m or more ahead of the first air blowing section 41, and more effectively, the cool air can be blown uniformly throughout the storage chamber S2. it can. Moreover, it does not specifically limit as a maximum static pressure of the 1st ventilation part 41, However, It is preferable that it is 1 Pa or more. The same applies to the second blower 42.

Next, the duct 6 will be described in detail. As shown in FIG. 5, one duct 6 is provided on each side of the storage chamber S2 (two in total). One end of each duct 6 is closed, and the other end on the opposite side is combined into one and connected to the intake port 28. A plurality of openings 61 are formed in the side walls of the portions arranged along the floor of each duct 6, and the air in the storage chamber S 2 can be guided into the duct 6 from these openings 61.

In particular, as in the present embodiment, by providing the opening 61 on the side wall of the duct 6, the opening 61 faces in a substantially horizontal direction (a direction inclined with respect to the vertical direction). The cool air that has flown (that is, the cool air sufficiently provided for cooling the storage chamber S 2) can be guided into the duct 6. In other words, it is possible to reduce the suction of cool air that can still be used sufficiently to cool the storage chamber S2. Therefore, the storage chamber S2 can be efficiently cooled. However, the direction of the opening 61 is not particularly limited, and may be inclined with respect to the horizontal direction and the vertical direction, or may be directed in the vertical direction.

The plurality of openings 61 are arranged along the extending direction of the duct 6 (the direction in which the cold air flows), and the opening area of the opening 61 on the one end side (the upstream side of the cold air flow) is It is larger than the opening area of the opening 61 on the end side (downstream side of the cold air flow). In particular, in the present embodiment, the opening areas of the plurality of openings 61 are gradually reduced from the one end side (upstream side of the cold air flow) toward the other end portion (downstream side of the cold air flow). Thereby, cold air can be uniformly guided into the duct 6 from all the openings 61, and the cold air can be circulated uniformly in the storage chamber S2.

Note that the arrangement pitch of the plurality of openings 61 is not particularly limited, and is preferably about 500 mm to 1000 mm, for example, although it varies depending on the size and shape of the storage chamber S2. Further, the opening shape (area) of the opening 61 is not particularly limited, and may vary depending on the size and shape of the storage chamber S2, but may be, for example, a square of length × width: about 30 mm × 30 mm to 100 mm × 100 mm. it can.

Although the duct 6 has been described above, the configuration of the duct 6 is not particularly limited as long as the air in the storage chamber S2 can be guided to the temperature adjustment unit 3.

Further, as shown in FIG. 2, the storage room S2 is provided with a plurality of temperature sensors 51 (indoor temperature detection units) for detecting the temperature in the storage room S2. These temperature sensors 51 can detect temperatures at a plurality of different locations in the storage chamber S2, and detect the temperature difference (the difference between the highest temperature and the lowest temperature in the storage chamber S2) ΔT in the storage chamber S2.

Although the arrangement of the plurality of temperature sensors 51 is not particularly limited, it is preferable that the plurality of temperature sensors 51 are arranged so as to be spread over the entire storage chamber S2. In the present embodiment, the temperature sensor 51 is arranged separately on the left and right side walls of the storage chamber S2, and is arranged so as to be shifted in the height direction. Since the cold air sinks downward in the vertical direction, a temperature difference is likely to occur in the height direction of the storage chamber S2. Therefore, by arranging the temperature sensors 51 side by side in the height direction, the temperature difference ΔT can be detected more accurately. Can do. The temperature sensor 51 is not particularly limited as long as the temperature can be detected. For example, a thermocouple or a thermistor can be used.

Further, as shown in FIG. 2, the storage room S2 is provided with a plurality of food temperature sensors 52 (object temperature detection units) for detecting the temperature of the food stored in the storage room S2. The temperature sensor 51 described above can detect the temperature in the vicinity of the temperature sensor 51, but it is difficult to detect the temperature of the food that is disposed away. Therefore, in the storage 1, a food temperature sensor 52 is disposed in addition to the temperature sensor 51, and the temperature of the food in the storage room S 2 is detected in addition to the temperature in the storage room S 2. By providing such a food temperature sensor 52, temperature adjustment with higher accuracy can be performed.

The temperature of the food may be, for example, the temperature of the food itself (for example, the surface temperature of the food, the center temperature), or when the food is packed in a packing box such as a cardboard box, It may be the surface temperature of the packaging box. In addition, when the position and state of food can be detected by the temperature sensor 51, the temperature sensor 51 may also serve as the object temperature detection unit. In this case, the food temperature sensor 52 may be omitted. .

The food temperature sensor 52 is not particularly limited as long as the temperature of the food can be detected. For example, an infrared array sensor can be used. The infrared array sensor is, for example, an element in which a plurality of thermopiles are arranged in an array, and is a sensor that can capture temperature on the surface. By using an infrared array sensor as the food temperature sensor 52, the food temperature sensor 52 can detect the position of the food. Thus, by detecting the position of the food in the storage room S2, for example, as described later, it becomes possible to blow cool air toward the specific food, and the specific food is given priority when necessary. Can be cooled to.

As described above, in the present embodiment, the food temperature sensor 52 also serves as the object position detection unit. However, as the object position detection unit, if the position of the food in the storage room S2 can be detected. Alternatively, it may be provided separately from the food temperature sensor 52. In this case, as the object position detection, for example, an image recognition technique using an imaging device such as a camera can be used.

Further, as shown in FIG. 6, the container 1 controls the driving of the temperature adjusting unit 3 based on the detection results of the temperature sensor 51 and the food temperature sensor 52, and each air blowing unit 4 (first and first). 2 has a control unit 7 for independently controlling the driving of the air blowing units 41 and 42).

Based on a temperature range (predetermined temperature range) T1 that is set according to the type of food, the control unit 7 controls the temperature adjusting unit 3 and each blowing unit so that the temperature in the storage chamber S2 is within the temperature range T1. And a second control mode for controlling the driving of the temperature adjusting unit 3 and each blowing unit 4 so that the food in the storage chamber S2 is within the temperature range T1. Yes.

In the first control mode, the temperature adjustment is performed while feeding back the detection results of the temperature sensors 51 so that the temperatures of all the temperature sensors 51 are within the temperature range T1 and the temperature difference between all the temperature sensors 51 is as small as possible. In this mode, the drive of the unit 3 (temperature adjustment of the cool air, the air volume, etc.) is controlled, and the drive of each blower unit 4 (the direction of the air blower 4, the air volume, etc.) is controlled. According to such a first control mode, the interior of the storage room S2 can be more reliably maintained within the temperature range T1 with relatively simple control, and the food in the storage room S2 can be maintained within the temperature range T1. Can be stored.

For example, as shown in FIG. 7, the storage chamber S2 is virtually divided into a plurality (18 in this embodiment) of blocks (areas) B, the temperature of each block B is in the temperature range T1, and each You may control the drive of the temperature adjustment part 3 and each ventilation part 4 so that the temperature difference of the block B may become as small as possible.

Further, the temperature range T1 (temperature in the storage chamber S2) is not particularly limited, but is preferably Tf−2.0 ° C. to Tf + 2.0 ° C. when the food freezing temperature is Tf (° C.). Tf−1.0 ° C. to Tf + 1.0 ° C. is more preferable. However, when the food is fruit and vegetables, a low temperature failure may occur. Therefore, the temperature range T1 is preferably Tf−2.0 ° C. to Tf + 15.0 ° C. Here, the moisture contained in the food causes a freezing point depression because it is a solution in which some solute is dissolved. Therefore, the freezing temperature of general foods is about -5 ° C to 0 ° C. Therefore, in the case of these foods, the temperature range T1 may be about -6.0 ° C to 15.0 ° C, preferably about -3 ° C to 0 ° C. Thereby, while being able to prevent the deterioration of the taste of food more effectively, the freshness of food can be maintained over a long period of time.

The second control mode is a mode selected when a food having a temperature higher than the temperature range T1 (a temperature outside the temperature range T1) is detected. In the second control mode, the food temperature higher than the temperature range T1 is preferentially cooled, and the temperature adjustment is performed while feeding back the detection result of the food temperature sensor 52 so that the food is quickly brought into the temperature range T1. While controlling the drive of the part 3, the drive of each ventilation part 4 is controlled. According to such a second control mode, the food can be cooled in a shorter time, and the damage to the food can be reduced.

In such a second control mode, the amount of cool air blown from the blower unit 4 toward the food (the amount of blown air) is larger than that in the first control mode, and accordingly, the food is more quickly produced than in the first control mode ( Can be cooled in a short time) For example, when the food 100 having a temperature higher than the temperature range T1 is arranged as shown in FIG. 8 and FIG. 9, the control unit 7 sets the second air blowing unit 42b more than the outputs of the second

air blowing units

42a and 42c. Reduce output. Or it drives so that the 2nd ventilation part 42b may be reversely rotated and cold air may be attracted | sucked. Then, under the influence of the airflow generated in the second air blowing unit 42, the cold air C1 from the first air blowing units 41a to 41d flows toward the food 100, and as a result, the food 100 is intensively cooled.

The first and second control modes have been described above. Such first and second control modes can be used in combination as follows.

For example, when food is stored in the storage room S2 that is previously maintained in the temperature range T1, the control unit 7 determines the temperature of the food and the storage room S2 based on information from the food temperature sensor 52. The position of is detected. If the temperature of the food is higher than the temperature range T1, the temperature in the storage chamber S2 increases due to the heat from the food, or temperature unevenness occurs. Foods are also easily damaged. Therefore, it is necessary to cool the food as quickly as possible. Therefore, when the temperature of the food is higher than the temperature range T1, the control unit 7 first cools the food quickly in the second control mode. When the temperature of the food falls within the temperature range T1, the control unit 7 switches from the second control mode to the first control mode and maintains the interior of the storage room S2 within the temperature range T1. That is, the control part 7 stops cooling food preferentially, and controls the drive of the temperature adjustment part 3 and the ventilation part 4 so that the temperature in the storage chamber S2 is maintained in the temperature range T1. According to such a method, food can be stably stored within the temperature range T1. As described above, by appropriately combining the first and second control modes, temperature adjustment with higher accuracy becomes possible.

According to such a container 1, food outside the temperature range T1 can be quickly cooled into the temperature range T1, so that food damage can be reduced. Furthermore, since the temperature difference ΔT in the storage chamber S2 can be kept small, the temperature of the storage chamber S2 can be set to a lower temperature while preventing freezing of food (destruction of the cell walls of the food due to freezing). . Thereby, the freshness of a foodstuff can be maintained over a long term. The temperature difference ΔT is preferably as small as possible. Specifically, the temperature difference ΔT is preferably within 2.0 ° C., more preferably within 0.5 ° C., and even more preferably 0 ° C. By setting it as such a numerical range, the said effect becomes more remarkable.

Moreover, as shown in FIG. 1, the storage 1 has a position detection unit 9 for detecting a position (current position). The position detection unit 9 is not particularly limited, and for example, a positioning system such as GPS (Global Positioning System) can be used. Moreover, as shown in FIG. 6, the storage 1 has a storage device 91. The storage device 91 includes, for example, the position information detected by the position detection unit 9 and the temperature in the storage chamber S2 at the position. Position / temperature information data including information is stored. Such position / temperature information data can be used as management history data, and it can be confirmed whether the container 1 was functioning normally during transportation. The storage 1 may further include a communication device 92 that communicates with an external terminal via a communication network N such as the Internet. If the communication device 92 is provided, for example, the position / temperature information data is periodically transmitted to the management terminal X that manages the storage 1 via the communication network N, or the position / The temperature information data can be confirmed, and the container 1 can be strictly monitored. Furthermore, if the storage 1 finds an abnormality (for example, the temperature of the storage room S2 is greatly deviated from the set temperature) by the position / temperature information data, for example, the storage 1 is remotely controlled via the control unit 7. 1 part (temperature adjustment part 3, ventilation part 4, electric field generation part 8, etc.) may be controllable.

The container 1 has been described above. For example, the container 1 may further include a controller for setting and monitoring the temperature in the storage room S2. For example, the controller is provided with an input unit for inputting a set temperature, a display unit that can display the temperature in the storage room S2, the arrangement of food, and the like. By having such a controller, the situation in the storage room S2 can be easily grasped, and the storage 1 with higher reliability can be obtained. In the case of the automobile 10 as shown in FIG. 1, for example, it is preferable to attach the controller to a position where the driver can operate and visually recognize the driver while sitting in the driver's seat.

The storage 1 of the first embodiment has been described above. The temperature adjustment system of the present invention has a configuration in which the main body 2 (the storage chamber S2) is omitted from the storage 1 as described above. According to the temperature adjustment system having such a configuration, for example, the above-described system can be introduced into an existing container or storage, and the functionality of the existing container or storage can be enhanced.

Second Embodiment
FIG. 10 is a vertical cross-sectional view of the storage case according to the second embodiment of the present invention. FIG. 11 is a cross-sectional view of the container shown in FIG. FIG. 12 is a perspective view showing a blower unit included in the storage case shown in FIG. 10. 13 to 16 are longitudinal sectional views for explaining an example of control by the control unit.

Hereinafter, the storage of the second embodiment will be described with a focus on the differences from the first embodiment described above, and description of similar matters will be omitted. In addition, the same code | symbol is attached | subjected to the structure similar to 1st Embodiment mentioned above.

The storage 1 shown in FIG. 10 has a main body 2, and the inside of the main body 2 is a storage chamber S2. That is, in the storage 1 of the present embodiment, the guide path S1 as in the first embodiment described above is not provided. The container 1 has a machine room R disposed outside the main body 2, and a temperature adjusting unit 3 is provided in the machine room R.

In addition, a plurality of air blowing sections 4 are provided near the ceiling of the storage room S2. Moreover, each ventilation part 4 is being fixed to the ceiling via the attitude | position change mechanism 43, and can change now into various attitude | positions. Therefore, efficient cooling according to the purpose is possible. As shown in FIG. 11, such a plurality of air blowing sections 4 are spread out almost uniformly throughout the accommodation chamber S 2 in a plan view viewed from the vertical direction.

As shown in FIG. 12, the posture changing mechanism 43 includes a fixing portion 431 fixed to the ceiling of the storage chamber S 2 and a connecting portion 432 that connects the fixing portion 431 and the air blowing portion 4. The connecting portion 432 can swing (turn) around the first axis J1 along the vertical direction with respect to the fixed portion 431, and the blower portion 4 can move horizontally with respect to the connecting portion 432 (first shaft). It can swing around the second axis J2 along the direction crossing J1. Further, the posture changing mechanism 43 swings the connecting portion 432 about the first axis J1 with respect to the fixed portion 431, and swings the blower portion 4 about the second axis J2 with respect to the connecting portion 432. And a drive source 434. These drive

sources

433 and 434 are, for example, motors, and the drive is controlled by the control unit 7.

According to such a posture changing mechanism 43, since the posture of the air blowing unit 4 can be changed three-dimensionally, the degree of freedom in the air blowing direction of the air blowing unit 4 is increased, and more accurate in the storage chamber S2. Temperature adjustment is possible. However, the configuration of the posture changing mechanism 43 is not limited to this as long as the posture of the blower unit 4 can be changed. For example, the posture changing mechanism 43 swings only around one of the first axis J1 and the second axis J2. It may be configured to be movable.

Further, the arrangement density of the air blowing units 4 is not particularly limited, and may vary depending on the size and power of the air blowing unit 4, but is preferably about 250 cm ² to 1 m ² / piece in a plan view, for example. As the maximum air volume of the blower unit 4 is not particularly limited, for ^example, it is preferably 4.0m ³ /min~5.0m 3 / min approximately. By using such an air volume, theoretically, it is possible to move the air up to 5 m or more ahead of the air blowing unit 4, and it is possible to blow cool air uniformly in the entire storage chamber S 2 more effectively. Moreover, it does not specifically limit as a maximum static pressure of the ventilation part 4, However, It is preferable that it is 1 Pa or more.

Further, as shown in FIG. 12, the blower unit 4 is provided with a food temperature sensor 52 for detecting the temperature of the food. The food temperature sensor 52 can be configured by an infrared array sensor in the same configuration as that of the first embodiment described above.

The food temperature sensor 52 is arranged so as to detect the temperature of food located in front of the blowing unit 4 in the blowing direction (front of the blowing unit 4). In particular, in the present embodiment, the blowing axis of the blowing unit 4 and the detection axis of the food temperature sensor 52 are substantially parallel. In this way, by disposing the food temperature sensor 52 in the same direction as the air blower 4, if the predetermined air blower 4 is directed to the food in order to blow cold air toward the predetermined food, the air blower 4 can detect the temperature of the food. On the contrary, if the food temperature sensor 52 is directed to the food in order to detect the temperature of the predetermined food, cold air can be blown toward the food by the blower unit 4 in which the food temperature sensor 52 is arranged. As described above, since the temperature detection of the food and the blowing of the cold air to the food can be performed with the same operation, various controls are simplified.

Further, as shown in FIG. 12, the air blowing unit 4 is provided with a distance sensor 53 (distance measuring unit) that measures the distance from the air blowing unit 4 to the food 100. The distance sensor 53 is not particularly limited as long as the distance can be measured. For example, a sonic distance sensor or a laser distance sensor can be used. The cost can be reduced by adopting a sonic distance sensor.

The distance sensor 53 is disposed so as to be able to detect the distance to the food located in front of the blowing section 4 in the blowing direction. In particular, in the present embodiment, the blowing axis of the blowing unit 4 and the detection axis of the distance sensor 53 are substantially parallel. In this way, by disposing the distance sensor 53 in the same direction as the blower 4, if the predetermined blower 4 is directed to the food in order to blow cool air toward the predetermined food, the blower 4 is directed to the blower 4. A distance to the food can be detected by the provided distance sensor 53. As described above, since the detection of the distance to the food and the blowing of the cold air to the food can be performed by the same operation, various controls are simplified.

Based on a temperature range (predetermined temperature range) T1 that is set according to the type of food, the control unit 7 controls the temperature adjusting unit 3 and each blowing unit so that the temperature in the storage chamber S2 is within the temperature range T1 A first control mode for controlling the driving of the temperature control unit 4, a second control mode for controlling the driving of the temperature adjusting unit 3 and the air blowing units 4 so that the food in the storage room S2 is within the temperature range T1, and the storage room S2. And a third control mode for controlling the drive of the temperature adjusting unit 3 and each of the air blowing units 4 so that the specific region within the temperature range T1.

In the first control mode, in order to circulate the cold air uniformly in the storage chamber S2 and to avoid the cold air from continuously hitting a specific food, at least one blower unit 4 is connected to the first axis J1 and the second axis J2. It may be swung around at least one of the axes. Moreover, the control part 7 calculates | requires the suitable attitude | position of each ventilation part 4 based on arrangement | positioning of the foodstuff in the storage chamber S2 detected by the food temperature sensor 52 grade | etc., And makes each ventilation part 4 the attitude | position corresponding to the result. Also good. According to such a method, the first control mode can be executed more effectively.

In the second control mode, it is preferable to drive the plurality of air blowing units 4 in cooperation in order to preferentially cool a specific food. That is, it is preferable that the plurality of blowing units 4 cooperate with each other to cool a specific food. For example, as shown in FIG. 13, when the food 100 is to be intensively cooled, at least two air blowing units 4 (4 a, 4 b, 4 c) located near the food 100 blow cool air toward the food 100. You may make it do. According to such a method, since the food 100 can be cooled with the cold air blown from the plurality of blowers 4, the food 100 can be cooled more quickly. For example, as shown in FIG. 14, when the food 100 is to be intensively cooled, the air blowing unit 4 (4 b) located immediately above (located in the vicinity of the food 100) cools the food 100 toward the food 100. And at least one other air blowing unit 4 (4a, 4c, 4d) may blow cool air to the air blowing unit 4b. According to such a method, since cold air can be supplied to the circumference | surroundings of the ventilation part 4b by the

ventilation parts

4a, 4c, and 4d, cold air can be efficiently blown toward the foodstuff 100 from the ventilation part 4b. . Therefore, the food 100 can be cooled more quickly. Thus, the second control mode can be more effectively executed by driving the plurality of air blowing units 4 in cooperation.

The third control mode is a mode for controlling the driving of the temperature adjusting unit 3 and controlling the driving of each blowing unit 4 so that a specific region in the storage chamber S2 is within the temperature range T1. According to such a third control mode, it is only necessary to adjust the temperature of a specific region (a part of the region) in the storage chamber S2, and thus, for example, power saving driving can be performed as compared with the first control mode. Furthermore, a plurality of regions maintained in different temperature ranges can be formed in the storage chamber S2.

For example, as shown in FIG. 15, in the case where the food 100 is disposed only in the region Sf on the front side of the storage chamber S2, there is a problem with storage of the food 100 if at least the region Sf is maintained in the temperature range T1. Does not occur. For this reason, in such a case, the temperature adjustment unit is configured so that the temperature of all the temperature sensors 51 in the region Sf is within the temperature range T1 and the temperature difference between all the temperature sensors 51 in the region Sf is as small as possible. 3 and the driving of each blower 4 are controlled (for example, only the blower 4 in the region Sf is driven). According to such control, power-saving driving can be performed.

Further, for example, as shown in FIG. 16, the food 100A is located in the region Sf, and the food 100B is located in the region Sr. Further, a temperature suitable for storage of the food 100A (temperature range T1 set as the temperature range of the region Sf). ') May be different from the temperature suitable for storage of the food 100B (temperature range T1 ″ set as the temperature range of the region Sr). In such a case, all the temperature sensors 51 in the region Sf. Is controlled to be in the temperature range T1 ′ and the temperatures of all the temperature sensors 51 in the region Sr are in the temperature range T1 ″. According to such control, foods of different varieties can be stored under appropriate temperature conditions.

The first, second, and third control modes have been described above. Such first, second, and third control modes can be used in combination as in the first embodiment described above.

Even in the second embodiment, the same effect as that of the first embodiment described above can be exhibited.

<Third Embodiment>
FIG. 17 is a vertical cross-sectional view of the storage case according to the third embodiment of the present invention. 18 is a cross-sectional view of the container shown in FIG. FIG. 19 is a perspective view showing a blower part included in the storage case shown in FIG. 17. 20 to 23 are diagrams illustrating driving of the air blowing unit illustrated in FIG. FIG. 24 is a cross-sectional view showing a drive mechanism of the blower.

Hereinafter, the storage of the third embodiment will be described with a focus on the differences from the first embodiment described above, and description of similar matters will be omitted. The container of this embodiment is the same as that of 1st Embodiment mentioned above except the structures of a ventilation part differing. In addition, the same code | symbol is attached | subjected to the structure similar to 1st Embodiment mentioned above.

In the storage 1 shown in FIG. 17, a plurality of openings 261 are formed in the top plate 26. Further, as shown in FIG. 18, the plurality of openings 261 extend and extend in the horizontal direction (Y-axis direction, a direction intersecting the flow direction of the cold air in plan view) of the container 1, and are spaced from each other. They are arranged side by side in the vertical direction (X-axis direction, the direction along the flow of cold air). These openings 261 are openings for introducing the cold air supplied from the temperature adjusting unit 3 to the guide path S1 into the storage chamber S2. And the ventilation part 4 is arrange | positioned at each of these opening 261. FIG.

The blower unit 4 is disposed on each opening 261, and can be switched between a closed state in which the opening 261 is closed and an open state in which the opening 261 is opened, and a driving mechanism 48 that drives each shutter unit 49. And have. The shutter portion 49 is not particularly limited as long as it can be bent and deformed. In the present embodiment, as shown in FIG. 19, the shutter portion 49 includes a plurality of bending movable portions 491 arranged side by side in the vertical direction. In 491, bending deformation (deflection deformation) can be performed in the thickness direction. Such a shutter unit 49 is driven as follows, for example.

For example, as shown in FIG. 20, introduction of cold air from the opening 261 to the storage chamber S2 is prohibited by closing the opening 261 with the shutter portion 49 closed. On the other hand, as shown in FIG. 21, the shutter portion 49 is slid forward (−X axis side, upstream in the direction of flow of cold air), and the shutter portion 49 is opened to open the opening 261, thereby opening the opening. Cold air is introduced from the H.261 to the storage chamber S2. Further, as shown in FIG. 22, the shutter portion 49 is slid forward, and the front portion 49a of the shutter portion 49 (at least a part of the shutter portion 49) is slid upward, so that the front portion 49a is one forward. By standing up behind the opening 261 so as to protrude into the guide path S1, cold air is guided along the front portion 49a, and the cold air is more efficiently introduced into the housing chamber S2 from the opening 261 one forward. be able to.

In FIG. 22, since the front portion 49a is inclined so as to fall forward, the cold air guided to the front portion 49a is introduced into the storage chamber S2 obliquely rearward. In addition, since the height of the front portion 49a (the protruding height into the guide path S1) is low, the amount of cool air introduced into the storage chamber S2 is small. On the other hand, in FIG. 23, since the front portion 49a stands substantially vertically (in the Z-axis direction, the direction perpendicular to the flow of cool air in the guide path S1), the cool air from the one front opening 261 is cool. Can be introduced into the storage room S2 so as to be almost directly below. Further, since the height of the front portion 49a is higher than that shown in FIG. 22, the amount of cool air introduced into the storage chamber S2 is larger than that shown in FIG. Thus, by changing the inclination and height of the shutter portion 49, the amount and direction of the cool air introduced into the storage chamber S2 can be changed.

As shown in FIG. 24, the drive mechanism 48 for driving the shutter portion 49 has a guide 481 provided on the main body 2 (inner wall 22) and a longitudinal direction along the guide 481 (a direction along the flow of cool air). A first moving unit 482 that is movable in the X-axis direction), a second moving unit 483 that is disposed in the first moving unit 482 and is movable in the height direction (Z-axis direction) with respect to the first moving unit 482, And a drive source (not shown) such as a motor for moving the first and second moving

units

482 and 483.

The front end of the shutter unit 49 is connected to the second moving unit 483. The guide 481 has a fan-shaped first guide part 481a arranged side by side with the opening 261 so as to overlap the opening 261 in a plan view as viewed from the Y-axis direction, and a linear shape connected to the first guide part 481a. The second guide portion 481b. The second moving part 483 can move substantially only in the vertical direction in the second guide part 481b, and the second moving part 483 can move in both the vertical direction and the height direction in the first guide part 481a. It is like that.

Then, for example, if the first moving part 482 is moved in the vertical direction so that the second moving part 483 moves along the second guide part 481b, the opening 261 is opened and closed as shown in FIGS. be able to. Further, when the second moving part 483 is in the first guide part 481a and the second moving part 483 is moved in the height direction with respect to the first moving part 482, as shown in FIGS. Further, the front portion 49a can be protruded into the guide path S1. Here, a boundary portion 481c between the first guide portion 481a and the second guide portion 481b is positioned corresponding to the rear end portion of the opening 261, and the shutter portion 49 is bent and deformed at the boundary portion 481c. . Therefore, as shown in FIGS. 22 and 23, it is possible to mainly change only the posture of the portion (front portion 49a) overlapping the opening 261 of the shutter portion 49. The driving of the first and second moving

units

482 and 483 is controlled by the control unit 7.

Even in the third embodiment, the same effect as that of the first embodiment described above can be exhibited.

<Fourth embodiment>
FIG. 25 is a longitudinal sectional view showing a blower part of the storage case according to the fourth embodiment of the present invention. FIG. 26 and FIG. 27 are diagrams for explaining driving of the air blowing unit shown in FIG. 28 and 29 are diagrams showing a modification of the air blowing unit shown in FIG.

Hereinafter, the storage of the fourth embodiment will be described with a focus on the differences from the first embodiment described above, and description of similar matters will be omitted. The container of this embodiment is the same as that of 3rd Embodiment mentioned above except that the structure of a ventilation part differs. In addition, the same code | symbol is attached | subjected to the structure similar to 1st Embodiment mentioned above.

The blower unit 4 of the present embodiment includes a plurality of shutter units 49 that can open and close each opening 261 and a drive mechanism 47 that drives each shutter unit 49. The configuration of the shutter unit 49 is the same as the configuration of the third embodiment described above.

As shown in FIG. 25, the drive mechanism 47 has a guide part 471 for guiding the shutter part 49 and a drive source (not shown) such as a motor for moving the shutter part 49 along the guide part 471. The guide portion 471 is located in front of the opening 261 and is connected to the first guide portion 471a extending upward as it goes forward and the rear end portion of the first guide portion 471a. And a linear second guide portion 471b extending to the rear side. Further, the first guide portion 471a is curved in a substantially arc shape, and the distance from the top plate 26 increases as it goes forward, and the inclination with respect to the top plate 26 increases.

As shown in FIG. 25, when the shutter part 49 is positioned on the opening 261, the opening 261 is closed by the shutter part 49. Then, as shown in FIG. 26, when the shutter portion 49 is guided by the second guide portion 471b from the closed state and moves to the rear of the opening 261, the opening 261 is opened and the guide path S1 passes through the opening 261. The cold air flowing through is introduced into the storage chamber S2. At this time, by controlling the rearward movement amount of the shutter portion 49, the opening area of the opening 261 can be controlled, and the amount of cool air introduced into the storage chamber S2 can be adjusted. On the other hand, as shown in FIG. 27, when the shutter portion 49 is guided by the first guide portion 471a from the closed state and moves forward, the opening 261 is opened, and the front portion is located in front of the opening 261. 49a stands and protrudes into the guide path S1. Then, the cold air flowing through the guide path S1 is guided to the tip end portion 49a and is introduced into the accommodation chamber S2 through the opening 261. At this time, by controlling the amount of forward movement of the shutter portion 59, the inclination and height of the front portion 49a can be controlled, and the amount of cool air introduced into the storage chamber S2 can be adjusted. . For example, if the moving distance of the shutter portion 49 from the closed state is shortened, the inclination and the height can be suppressed small, and the amount of cool air introduced from the opening 261 into the storage chamber S2 is reduced. On the contrary, if the movement distance is long, the inclination and the height are increased, and the amount of cold air introduced from the opening 261 into the accommodation chamber S2 is increased. Thus, by changing the inclination and height of the shutter portion 49, the amount and direction of the cool air introduced into the storage chamber S2 can be changed. The driving of the shutter unit 49 can be controlled by the control unit 7.

Even in the fourth embodiment, the same effects as those of the first embodiment described above can be exhibited. In the present embodiment, the first guide portion 471a has a substantially arc shape, and the inclination of the shutter portion 49 when guided by the first guide portion 471a can be controlled steplessly. The configuration of the guide portion 471a is not limited to this. For example, as shown in FIG. 28, the first guide portion 471a may be linear, and the inclination of the front portion 49a may be constant regardless of the amount of movement. As shown in FIG. 29, the first guide portion 471a may have a plurality of linear portions with different inclinations, and the inclination of the front portion 49a may be changed in multiple stages.

<Fifth Embodiment>
FIG. 30 is a longitudinal sectional view showing a storage case according to the fifth embodiment of the present invention.

Hereinafter, the storage of the fifth embodiment will be described with a focus on the differences from the first embodiment described above, and description of similar matters will be omitted. The container of this embodiment is the same as that of 1st Embodiment mentioned above except having further an electric field generation | occurrence | production part. In addition, the same code | symbol is attached | subjected to the structure similar to 1st Embodiment mentioned above.

As shown in FIG. 30, the storage 1 of the present embodiment has an electric field generator 8 that forms an electric field (vibrating electric field) in the storage room S2. By causing the electric field generated by the electric field generator 8 to act on the food 100 in the storage room S2, the food 100 can be sterilized and the aging of the food 100 can be promoted. Therefore, the food 100 can be stored for a longer period while maintaining the freshness, and the umami of the food 100 can be amplified.

The configuration of the electric field generating unit 8 is not particularly limited, but the electric field generating unit 8 of the present embodiment applies a voltage to the plate 81 disposed on the floor surface of the storage chamber S2 via the spacer 83, and the plate 81. And a voltage applying unit 82 to be applied. The plate 81 also serves as a mounting table on which the food 100 is placed, and the food 100 is stacked on the plate 81. The plate 81 is made of a conductive material such as aluminum and functions as an electrode for generating an electric field. Such a plate 81 is installed in a state of being insulated from the main body 2. For example, a sufficient number of through holes (not shown) are preferably formed in the plate 81 so that the plate 81 does not hinder the suction of cold air from the duct 6 (opening 61). The voltage application unit 82 can be disposed in the machine room R.

Further, the spacer 83 is not particularly limited, but it is preferable to use a spacer having a shock absorbing mechanism (for example, a coil spring, a cylinder, a gel-like shock absorbing material, etc.). This makes it difficult for the impact generated by the movement of the automobile 10 to be transmitted to the food 100. Therefore, for example, the food 100 is hardly damaged, and the freshness of the food 100 can be more effectively maintained.

The strength of the electric field acting on the food 100 is not particularly limited, but is preferably, for example, 1000 V / m to 10,000 V / m. The frequency of the electric field (the frequency of the alternating voltage applied to the plate 81) is not particularly limited, but is preferably 5 Hz or more, more preferably 100 Hz to 1000 Hz or less. Thereby, the said effect (bactericidal effect and aging effect) becomes more remarkable. It should be noted that the ripening speed of the food 100 can be adjusted by adjusting the frequency. Therefore, it is preferable to appropriately set the frequency according to the type of food 100, the time (number of days) required for transportation, and the like. The electric field may be generated continuously or intermittently. By intermittently generating an electric field, the sterilization effect is improved, although the aging effect is reduced as compared with the case where the electric field is continuously generated. In addition, power consumption can be reduced. In particular, by changing the environment 2 in the storage room S2 within 20 minutes, that is, the period of electric field generation (the time from the disappearance of the nth electric field to the generation of the n + 1th electric field). By making it within 20 minutes, division (growth) of various bacteria such as Escherichia coli and Staphylococcus aureus can be effectively prevented, and the bactericidal effect is further improved. Further, the electric field generation time for each generation when the electric field is intermittently generated is not particularly limited, but is preferably about 10 seconds to 10 minutes, for example. By setting the lower limit, a sufficient sterilizing effect can be exhibited, and by setting the upper limit, the environment in the storage chamber S2 can be reliably changed within 20 minutes. In addition, when generating an electric field continuously, by changing the intensity of the electric field within 20 minutes (for example, by switching between an electric field of 1000 V / m and an electric field of 10,000 V / m in a cycle of 10 minutes), 20 minutes The environment in the storage chamber S2 can be changed within the range, and the sterilizing effect similar to the above can be exhibited.

The electric field generator 8 is preferably provided with a safety device for preventing an electric shock or a fire. For example, the safety device is provided with a sensor that detects opening and closing of a door installed in the main body 2, and is configured to stop voltage application from the voltage application unit 82 when the door is opened in conjunction with the sensor. It may be.

It is sufficient that the temperature can be lowered or raised. That is, if the object is used only when stored at a low temperature, it is sufficient if at least cold air can be supplied, and if the object is used only when stored at a high temperature, It is sufficient if at least hot air can be supplied.

In the above-described embodiment, the accommodation chamber is filled with air. However, the atmosphere in the accommodation chamber does not need to be filled with air, and a gas other than air (for example, nitrogen, argon, etc.) Inert gas), and the temperature of the gas may be adjusted by the temperature adjusting unit.

In the above-described embodiment, the machine room is arranged outside the main body. However, the arrangement of the machine room is not limited to this and may be arranged inside the main body. In particular, when used for a cargo container or the like, since the size of the container is usually determined, it is preferable to arrange the machine room inside the main body.

The storage of the present invention includes a storage chamber that stores an object, a temperature adjustment unit that adjusts the temperature of air in the storage chamber, a blower that blows air whose temperature is adjusted by the temperature adjustment unit, and the storage chamber At least one of the indoor temperature detector, the indoor temperature detector, and the object temperature detector, the indoor temperature detector that detects the temperature of the object, the object temperature detector that detects the temperature of the object disposed in the storage chamber, And a control unit that controls driving of the air blowing unit based on the detection result. Therefore, in addition to the temperature of the storage chamber, the temperature of the target object stored in the storage chamber can be detected, and the target object can be more reliably stored in a predetermined temperature range. In particular, when the temperature of the object is high (low), the object is first cooled (heated) preferentially, and when the temperature of the object is sufficiently lowered (increased), By maintaining the temperature uniformly and within a predetermined temperature range, the object can be quickly cooled (heated), and the above effects become more remarkable. Therefore, the storage of the present invention has industrial applicability.
