This application is based on Japanese Patent Application No. 2017-009563 filed on Jan. 23, 2017, the disclosure of which is incorporated into this application by reference.

This disclosure relates to a temperature control storage device that accommodates a temperature control object to be temperature controlled.

Patent Document 1 discloses a temperature-controlled storage device. In this temperature control storage device, since the outlet and the suction port are provided at diagonal positions in the accommodation space, the conditioned air can be passed through all the accommodation items. The temperature control storage device has a shutter made of a flexible film member provided to hang down from the ceiling of the accommodation space. By arranging the shutter so as to close the space between the storage object and the ceiling of the storage space, the cool air can be prevented from passing through the upper gap.

Japanese Patent Laying-Open No. 2015-161488

The temperature control storage device of Patent Document 1 has a limit in allowing air-conditioning air to flow uniformly throughout the entire package, and further improvement in temperature control unevenness is required. Furthermore, if the amount of the stored item is small, the upper gap of the stored item cannot be sufficiently closed by the shutter, and there is a problem that the conditioned air passes through the upper gap. In addition, if the gap between the stored items becomes large when arranging the stored items, there is a problem that the amount of conditioned air that does not contribute to the temperature adjustment of the stored items blown through the gap increases. That is, the temperature control storage device of Patent Document 1 has a poor workability because the temperature control performance tends to be lowered depending on the amount or arrangement of the stored items, and the stored items must be stored in consideration of this. Moreover, since the operation | work which arrange | positions a shutter is needed in the accommodation operation | work of an accommodation thing, workability | operativity is bad also in this point.

The purpose of the present disclosure is to provide a temperature control storage device that can improve temperature control unevenness and improve workability.

A temperature control storage device according to a feature example of the present disclosure includes a housing having a storage chamber in which a temperature control object is accommodated, and a blower, and is integrally installed in the housing, and the storage chamber is configured by the blower. An air conditioner that produces conditioned air to be blown into the air, a blowout unit that blows out the conditioned air blown by the blower toward the storage room, a suction part that sucks the conditioned air that has passed through the storage room, and a storage room and a suction part And a partition member that partitions and forms a differential pressure forming chamber that is negative with respect to the storage chamber. The partition member is provided below the wind shield part and a wind shield part that blocks the ventilation of the conditioned air from the ceiling part of the storage room to a predetermined height, and the conditioned air receives ventilation resistance from the storage room to the differential pressure forming room. And a rectifying unit that can pass through.

According to this disclosure, a flow in which conditioned air is sucked from the storage chamber into the differential pressure forming chamber is formed by forming the differential pressure forming chamber with the partition member. Since the partition member has the wind shielding portion and the rectification portion, the conditioned air passing through the partition member flows so as to be offset toward the rectification portion. Due to the flow of the conditioned air that is biased toward the rectifying unit, the conditioned air can be uniformly passed through the space in the storage room where the temperature control object can be accommodated. Thereby, temperature control nonuniformity can be improved. In addition, the flow of the conditioned air that is biased toward the rectifying unit side is formed regardless of the amount or arrangement of the temperature control object. Therefore, it can suppress that an air conditioning wind blows through the upper part of a temperature control object. In addition, even when the gap between the temperature adjustment object and the temperature adjustment object is large, the amount of conditioned air that does not contribute to temperature adjustment can be suppressed by uniform ventilation. That is, it is possible to suppress a decrease in temperature adjustment performance due to the amount and arrangement of the temperature adjustment object, thereby improving workability. Furthermore, since it is not necessary to install a shutter or the like in the operation of housing the temperature control object, workability can be improved in this respect. As described above, it is possible to provide a temperature control storage device that can improve temperature control unevenness and improve workability.

(First embodiment)
The temperature control storage device to be disclosed is a device capable of transporting a temperature control object accommodated in a storage chamber in a frozen state or a refrigerated state, for example. The temperature control storage device is carried on a moving body such as a vehicle, a ship, or an aircraft. During the transportation, the temperature control storage device is mounted as a transportation container. The temperature controlled objects to be transported are fresh foods such as vegetables, fruits and meat, and various frozen foods transported in a frozen state. Further, the temperature control object can be a living thing or an article that is not food but needs to be transported at a predetermined temperature.

In the first embodiment, a temperature control storage device 1 capable of controlling the temperature control object 10 accommodated in the transport container 3 to a predetermined temperature will be described with reference to FIGS. The vertical direction shown in the drawing is a direction orthogonal to both the depth direction and the width direction, and the depth direction is a direction orthogonal to both the vertical direction and the width direction. The width direction is a direction orthogonal to both the vertical direction and the depth direction. Moreover, in each figure, in order to make it easy to understand the configuration of the temperature control storage device, the built-in parts of the container are indicated by solid lines.

The temperature control storage device 1 is a box-shaped device in which an air conditioner 2 is integrally assembled with a container 3, which is an example of a casing, and is stored in the ventilation space 30 in the container 3 by the conditioned air generated by the air conditioner 2. The temperature adjustment object 10 accommodated in the chamber 30A is adjusted to a predetermined temperature. Here, an example of the temperature control object 10 is a large number of plastic computers or cardboard boxes containing fruits and vegetables such as vegetables and fruits. The platen is an abbreviation for a plastic box having a structure in which a mesh-like ventilation surface is formed on a side surface and a bottom surface, and can be fitted and stacked in the vertical direction. The cardboard box has vent holes on the side and bottom. The conditioned air flowing through the storage chamber 30A enters and exits the inside of the placon and the cardboard box through this ventilation hole.

The air conditioner 2 air-conditions, for example, a refrigeration cycle device, a heat radiating fan, a blower 21 that drives conditioned air, a blower duct 22 in which conditioned air flows toward the storage chamber 30A, and a control device that controls the operation of each device. It is a device configured as a unit. The refrigeration cycle apparatus is a refrigerant circuit configured by connecting, for example, an electric compressor, a condenser, an expansion valve, an evaporator 20 and the like in an annular shape, and the refrigerant circulates by the driving force of the electric compressor. Among the air conditioners 2, the refrigeration cycle device, the heat dissipating fan, the blower 21, and the control device are attached to one end in the depth direction of the container 3, and the blower duct 22 is one of the depth direction with respect to the container 3. Mounted on the end and bottom. Hereinafter, one end portion in the depth direction is referred to as a front portion for convenience of explanation.

An electric compressor is configured by combining an electric motor and a compression mechanism. In the electric compressor, the compression mechanism is driven by the electric motor, and the control device controls the voltage applied to the electric motor to control the operation state of the refrigeration cycle. Be controlled. As described above, the air duct 22 extends in the vertical direction at the front portion of the container 3 and further forms an air passage extending in the depth direction at the bottom portion of the container 3. The blower duct 22 is a member constituting an air passage for sucking the air in the storage chamber 30A and returning it to the storage chamber 30A, and the blower 21 and the evaporator 20 are installed therein.

The heat dissipating fan is an electric fan that forcibly exchanges heat between the condenser and the air outside the container 3, and the air volume is controlled by a control device. The blower 21 is an electric fan for sucking the air in the storage chamber 30A into the blower duct 22 and blowing out the air that has passed through the evaporator 20 to the storage chamber 30A again, and the air volume is controlled by the control device.

Also, the control device acquires the cold air temperature from a temperature sensor that detects the temperature of the cold air blown into the storage chamber 30A. The control device controls the electric motor and the like of the electric compressor so that the temperature of the storage chamber 30A maintains the set temperature based on the set temperature set and the cold air temperature acquired from the temperature sensor. For example, the control device controls the rotational speed of the compressor by performing inverter control of the energization amount of the electric motor based on the set temperature and the cold air temperature. In addition, the control device controls the heat radiation amount of the condenser by controlling on / off of energization to the electric motor of the heat dissipating fan according to the operating state of the refrigeration cycle apparatus.

The ventilation space 30 in the container 3 has an air outlet 23 through which the conditioned air created by the air conditioner 2 is blown out to the ventilation space 30 and a suction port 24 that returns the air in the ventilation space 30 to the air conditioner 2. . The air outlet 23 is an air-conditioned air outlet that opens at the downstream end of the air duct 22, and is located at the lower end of the other end in the depth direction in the ventilation space 30. Hereinafter, the other end portion in the depth direction is referred to as a rear portion for convenience of explanation. Therefore, the air outlet 23 opens at the lower end of the rear part in the ventilation space 30. The suction port 24 is a suction portion through which the conditioned air flowing through the storage chamber 30 A and the differential pressure forming chamber 30 B formed in the ventilation space 30 flows out from the ventilation space 30, and is positioned at the upper end of the front portion in the ventilation space 30. To do. Accordingly, the air outlet 23 and the air inlet 24 are diagonally positioned in the ventilation space 30 and are provided at locations farthest from each other. The ventilation space 30 is partitioned by the partition plate 6 into two chambers, a storage chamber 30A and a differential pressure forming chamber 30B.

The partition plate 6 has a wind shielding part 6a and a rectifying part 6b. The partition plate 6 is a plate member formed of a metal material such as aluminum. For example, the partition plate 6 is a flat plate parallel to the height direction and the width direction. The partition plate 6 is set apart from the suction port 24 by a predetermined distance. The partition plate 6 partitions the ventilation space 30 so that the air outlet 23 and the suction port 24 open to different chambers. More specifically, the partition plate 6 partitions the ventilation space 30 such that the air outlet 23 opens to the storage chamber 30A and the suction port 24 opens to the differential pressure forming chamber 30B. In other words, of the two chambers of the ventilation space 30 partitioned by the partition plate 6, the chamber in which the air outlet 23 opens is the storage chamber 30A, and the chamber in which the suction port 24 opens is the differential pressure forming chamber 30B. . That is, the storage chamber 30 A is a chamber formed between the outlet 23 and the differential pressure forming chamber 30 B, and the differential pressure forming chamber 30 B is formed between the storage chamber 30 A and the suction port 24. It is a room. The partition plate 6 partitions the ventilation space 30 so that the volume of the storage chamber 30A is larger than the differential pressure forming chamber 30B.

The partition plate 6 is fixed to the container 3 and installed. For example, the partition plate 6 is fixed to a predetermined position by being screwed to a frame portion formed on a ceiling portion, a wall portion, and a bottom portion of the ventilation space 30. In the wall portion of the container 3 that partitions the storage chamber 30 A, an inlet portion such as a door for carrying the temperature-controlled object 10 into the interior is provided. Therefore, the temperature control object 10 cannot be accommodated in the differential pressure forming chamber 30B.

The wind shield 6a is an area that blocks the ventilation of the conditioned air in the partition plate 6. The air shielding part 6a is configured as a plate part in which openings such as holes and slits are not formed, and has a structure that can block the ventilation of the conditioned air. The wind shielding portion 6a is a portion having a predetermined dimension from the ceiling portion of the ventilation space 30 in the partition plate 6 to a predetermined height below. That is, the air shield 6a prevents the conditioned air from passing from the storage chamber 30A to the differential pressure forming chamber 30B above the ventilation space 30.

The rectifying unit 6b is a region in the partition plate 6 that allows ventilation of the conditioned air. The rectifying unit 6b is provided below the wind shield 6a. The rectifying unit 6b is configured, for example, as a so-called punching metal having a plurality of holes 61 formed therein. The plurality of holes 61 are formed over the entire rectifying unit 6b. In FIG. 1, the plurality of hole portions 61 are illustrated as circular through holes, but the shape is not limited. For example, the hole portions 61 may be polygonal through holes. The plurality of holes 61 are formed, for example, so that the number and size per unit area in the rectifying unit 6b are constant. In other words, the plurality of hole portions 61 are formed in the entire region of the rectifying portion 6b without any deviation. The conditioned air passing through the rectifying unit 6b flows from the storage chamber 30A through the plurality of holes 61 to the differential pressure forming chamber 30B. In the rectifying unit 6b, a portion where the plurality of holes 61 are not formed is a resistance unit 62 that provides ventilation resistance to the conditioned air passing through the rectifying unit 6b.

The rectifying unit 6b has a vertical dimension from the bottom of the storage chamber 30A to the height of the lower end of the wind shield 6a. The vertical dimension of the rectifying unit 6b is equivalent to the maximum height at which the temperature control object 10 can be accommodated. That is, the suitable maximum accommodation amount of the temperature control object 10 is determined by the vertical dimension of the rectifying unit 6b. The vertical dimension of the rectifying unit 6b is determined in consideration of, for example, workability in the operation of housing the temperature control object 10. Or the maximum accommodation amount of the temperature control object 10 may be determined from the weight etc. which the temperature control storage apparatus 1 can store, and the up-down dimension of the rectification | straightening part 6b may be determined from this maximum accommodation amount.

The opening ratio of the rectifying unit 6b is between 0.5% and 30%. Here, the opening ratio is a ratio of the opening area of the plurality of hole portions 61 to the area of the rectifying portion 6b. The opening ratio of the rectifying unit 6b is appropriately set with respect to the air volume of the air blown by the blower 21.

The first guide plate 5a and the second guide plate 5b are air direction guide members that guide the air direction of the conditioned air blown out from the air outlet. In the following, when there is no need to particularly distinguish the first guide plate 5a and the second guide plate 5b, they may be simply referred to as guide plates. The guide plate is a rectangular plate having a width direction length equal to or greater than the width direction length of the air outlet 23 at a position corresponding to the air outlet 23. Therefore, the guide plate is provided over the entire range of the width of the air outlet 23. The guide plate is provided with its angle set so that the direction of the conditioned air blown out from the outlet is directed toward the front of the storage chamber 30A. In the temperature control storage device 1, the two guide plates of the first guide plate 5a and the second guide plate 5b are arranged in the vertical direction.

The first guide plate 5a is a guide plate provided below the second guide plate 5b and guides part of the conditioned air blown from the outlet 23 toward the front of the storage chamber 30A. The first guide plate 5a is formed with an opening 51 through which the remainder of the conditioned air passes when blown through the second guide plate 5b. The opening 51 is an opening having an opening area such that the air volume of the conditioned air guided by the first guide plate 5a is equal to the air volume of the conditioned air guided by the second guide plate 5b.

The second guide plate 5b is a wind direction guide member that guides the wind direction of the conditioned air that has passed through the opening 51 of the first guide plate 5a. The 1st guide plate 5a and the 2nd guide plate 5b are each installed in the height by which the conditioned air branched by these two guide plates is guided at equal intervals with respect to the height of the rectification part 6b.

Since the two guide plates are installed in the vertical direction, the conditioned air blown from the outlet 23 is adjusted so that the flow is distributed in the vertical direction and guided to the storage chamber 30A. Thereby, the layer of the flow of the conditioned air in the height region of the rectifying unit 6b described later is more easily formed. Three or more guide plates may be installed in the vertical direction. The greater the number of guide plates installed in the vertical direction, the easier it is to form a layer of conditioned air flow with respect to the rectifying unit 6b.

The guide plate may be configured such that the vertical angle can be changed. That is, by adjusting the angle of the guide plate, the air-conditioning air blowing angle may be adjusted to a desired angle at the site of loading the load or at the shipment stage or delivery stage of the temperature control storage device 1. Further, the height of the guide plate may be configured to be changeable by a configuration in which the guide plate is installed to be slidable in the vertical direction by a rail or the like. According to such a structure, in order to form the flow of the air-conditioning air which can adjust the air-conditioning air more efficiently by arrangement | positioning of the temperature control object 10, the wind direction of an air-conditioning air can be adjusted.

Next, the flow of the conditioned air flowing through the ventilation space 30 will be described with reference to FIGS. When the air conditioner 2 is activated, the blower 21 starts to blow air. By this blowing, a differential pressure is generated before and after the blower 21. That is, the air between the partition plate 6 and the blower 21 is sucked out by the blower 21 and blown out from the blower 21 to the space from the blower 21 through the blower duct 22 to reach the partition plate 6. The section from to the blower 21 has a negative pressure relative to the other sections. This is because the air conditioner 2 sucks the air in the differential pressure forming chamber 30B from the suction port 24 and blows it out from the outlet 23 to the storage chamber 30A, so that the differential pressure forming chamber 30B becomes a negative pressure with respect to the storage chamber 30A. In other words, Thereby, a differential pressure is formed between the differential pressure forming chamber 30B and the storage chamber 30A.

The conditioned air blown from the outlet 23 to the storage chamber 30A is guided in the direction of the rectifying unit 6b by the

guide plates

5a and 5b. Due to the differential pressure between the differential pressure forming chamber 30B and the storage chamber 30A, the conditioned air in the storage chamber 30A is sucked by the rectifying unit 6b. That is, the conditioned air is sucked in a distributed manner with respect to all of the plurality of holes 61 formed in the rectifying unit 6b. In addition, the conditioned air passing through the height region of the wind shield 6a is blocked from passing from the storage chamber 30A to the differential pressure forming chamber 30B by the wind shield 6a. Therefore, the conditioned air flowing through the height region of the wind shield 6a flows through the storage chamber 30A so as to be guided to the rectifier 6b by the wind shield 6a. For this reason, in the storage chamber 30A, the conditioned air flows over the entire vertical region where the rectifying unit 6b is formed. That is, the conditioned air that flows through the storage chamber 30A flows toward the rectifying unit 6b side by the wind shield 6a and the rectifying unit 6b formed on the partition plate 6. In other words, a layer of conditioned air flow is formed in the storage chamber 30A in the height region of the rectifying unit 6b.

As described above, the layer of the conditioned air flow formed in the storage chamber 30 A is due to the negative pressure formed in the differential pressure forming chamber 30 B by the partition plate 6. Regardless, it is formed. Therefore, for example, even if the temperature control object 10 is arranged with a gap as shown in FIG. 2, it can be suppressed that the flow of the conditioned air flowing through the gap becomes dominant. Air-conditioning air is evenly distributed. Thus, even if the amount or arrangement of the temperature control object 10 is appropriately changed, the conditioned air is uniformly supplied to all the temperature control objects 10 accommodated in the storage chamber 30A. That is, uneven temperature control of the temperature control object 10 can be improved.

As shown in FIG. 4, the temperature adjustment object 10 accommodated in the storage chamber 30A may be accommodated with a height exceeding the height of the rectifying unit 6b. The flow of the conditioned air in the storage room 30A is shifted toward the rectifying unit 6b, but a part of the conditioned air flows through a region higher than the height of the rectifying unit 6b, that is, the height region of the wind shielding unit 6a. Thereafter, a flow is formed that is sucked into the hole 61 above the rectifying unit 6b. Therefore, even if the temperature controlled object 10 is loaded higher than the height of the rectifying unit 6b, the conditioned air is passed through all the temperature controlled objects 10 by the flow of this part of the conditioned air. be able to.

The conditioned air passing through the storage room 30A adjusts the temperature of the temperature adjustment object 10 accommodated in the storage room 30A to a predetermined temperature. Since the partition plate 6 forms a uniform flow of conditioned air in the storage chamber 30A, the conditioned air passes through all the temperature control objects 10 accommodated in the storage chamber 30A. Therefore, the temperature control object 10 is all temperature-controlled.

Next, the effect which the temperature control storage apparatus 1 of 1st Embodiment brings is demonstrated. The temperature control storage device 1 is installed integrally with the container 3 having a storage chamber 30 A in which the temperature control object 10 is accommodated, and creates conditioned air that is blown to the storage chamber 30 A by the blower 21. The air conditioner 2 is provided. The temperature control storage device 1 includes an air outlet 23 that blows out the conditioned air blown by the blower 21 toward the storage chamber 30A, and a suction port 24 that is provided through the air outlet 23 and the storage chamber 30A and sucks the air conditioned air. Prepare. The temperature-controlled storage device 1 includes a partition plate 6 that partitions and forms a differential pressure forming chamber 30B that is negative with respect to the storage chamber 30A between the storage chamber 30A and the suction port 24. The partition plate 6 is provided below the wind shield 6a and the wind shield 6a that blocks the ventilation of the conditioned air from the ceiling of the storage chamber 30A to a predetermined height. And a rectifying unit 6b that can pass through 30B while receiving ventilation resistance.

According to this temperature control storage device 1, by forming the differential pressure forming chamber 30B with the partition plate 6, a flow in which conditioned air is sucked from the storage chamber 30A into the differential pressure forming chamber 30B is formed. Since the partition plate 6 includes the wind shielding portion 6a and the rectifying portion 6b, the conditioned air passing through the partition plate 6 flows so as to be offset toward the rectifying portion 6b side. Due to the flow of the conditioned air that is biased toward the rectifying unit 6b, the conditioned air can be uniformly passed through the space in the storage chamber 30A in which the temperature controlled object 10 can be accommodated. Thereby, temperature control nonuniformity can be improved. In addition, the flow of the conditioned air that is biased toward the rectifying unit 6b is formed regardless of the amount or arrangement of the temperature-controlled object 10. Therefore, the conditioned air can be prevented from blowing through the upper part of the temperature adjustment object 10 or between the temperature adjustment object 10 and the temperature adjustment object 10. That is, it is possible to suppress a decrease in the temperature adjustment performance due to the amount and arrangement of the temperature adjustment object 10, thereby improving workability. Furthermore, since it is not necessary to install a shutter or the like in the operation of housing the temperature control object 10, workability can also be improved in this respect. As described above, it is possible to provide a temperature control storage device 1 that can improve temperature control unevenness and improve workability.

The partition plate 6 is fixed at a predetermined position inside the container 3. According to this, since the partition plate 6 is provided in the container 3 in advance, it is not necessary for the worker to attach the partition plate 6 when accommodating the temperature control object 10. Therefore, workability can be further improved.

The partition plate 6 is a plate-like member that integrally includes a wind shielding portion 6a and a rectifying portion 6b. According to this configuration, the partition plate 6 can be easily assembled to the container 3 as compared with the case where the wind shield 6a and the rectifying unit 6b are installed separately.

The rectifying unit 6b has a plurality of holes 61 through which the conditioned air can flow. According to this, the conditioned air is sucked into the entire rectifying unit 6b. Therefore, the conditioned air can be evenly ventilated in the height region of the rectifying unit 6b in the storage chamber 30A. Therefore, the temperature control unevenness in the storage chamber 30A can be further improved.

The temperature control storage device 1 has a plurality of guide plates in the vertical direction for guiding the conditioned air blown into the storage chamber 30A. According to this, since it can adjust so that the flow of the conditioned air which blows off to 30 A of storage chambers may be distributed to an up-down direction, the layer of the conditioned air flow by the rectification | straightening part 6b can be formed more easily.

The temperature control storage device 1 is transported by at least one of a vehicle, a ship, and an aircraft. According to this, the temperature control storage apparatus 1 is applicable to the container for conveyance conveyed by the at least 1 mobile body of a vehicle, a ship, and an aircraft. Since the container for transportation accommodates the temperature-controlled object 10 over a relatively long period of time, there is a high need for uniformly adjusting the temperature-controlled object 10 without temperature unevenness. Therefore, by applying the temperature control storage device 1 to such a container, the effect of improving the temperature control unevenness is great.

(Second Embodiment)
A second embodiment will be described with reference to FIG. In the second embodiment, components having the same reference numerals as those in the drawing according to the first embodiment and configurations not described are the same as those in the first embodiment and have the same effects. In the second embodiment, only parts different from the first embodiment will be described.

In the temperature control storage device 1 of the second embodiment, the air duct 222 extends in the vertical direction at the front portion of the container 3 and further forms an air passage extending in the depth direction at the ceiling portion of the container 3. In the ventilation space 30, the blower outlet 23 is located in the upper end of the other edge part of a depth direction. That is, the blower outlet 23 opens at the upper end of the rear part in the ventilation space 30. The suction port 24 is located at the lower end of the front portion in the storage chamber 30A. That is, the conditioned air is blown out from the upper end of the rear portion of the storage chamber 30A, is sucked into the rectifying unit 6b by the differential pressure formed in the differential pressure forming chamber 30B, and is sucked in from the lower end of the front portion of the differential pressure forming chamber 30B.

The first guide plate 5a and the second guide plate 5b are provided such that the first guide plate 5a is located above and the second guide plate 5b is located below. The angle and position of the guide plate are adjusted so as to guide the conditioned air blown from the upper end of the rear portion of the storage chamber 30A to the rectifying unit 6b.

Also in the temperature control storage device 1 of the second embodiment, a negative pressure with respect to the storage chamber 30A can be applied to the differential pressure forming chamber 30B. Therefore, the conditioned air can be ventilated like a layer through the portion of the storage chamber 30A where the temperature control object 10 can be accommodated, and the same effect as the temperature control storage device 1 of the first embodiment can be obtained. .

(Third embodiment)
A third embodiment will be described with reference to FIG. In 3rd Embodiment, the component which attached | subjected the same code | symbol as drawing concerning 1st Embodiment, and the structure which is not demonstrated are the same as that of 1st Embodiment, and there exists the same effect. In the third embodiment, only parts different from the first embodiment will be described.

In the temperature control storage device 1 of the third embodiment, the air duct 222 forms an air passage extending in the depth direction at the ceiling of the container 3.

In the above-described embodiment, the plurality of holes 61 formed in the rectifying unit 6b are uniform in number and size throughout, but the number and size are changed depending on the region. Also good. For example, the plurality of hole portions 61 may be configured such that the number is reduced or the size is reduced toward the upper portion of the rectifying portion 6b. In other words, the rectifying unit 6b may have a configuration in which the ventilation resistance increases toward the top. In this configuration, the airflow rate of the conditioned air becomes smaller toward the upper part of the rectifying unit 6b. For this reason, even when a part of the conditioned air passes through a position higher than the rectifying unit 6b, the part of the conditioned air is concentrated and blown on the upper part of the rectifying unit 6b, and the upper part of the temperature control object 10 is blown. It is possible to suppress temperature control unevenness due to concentration of air-conditioned air.

In the above-described embodiment, the partition plate 6 is a single plate member in which the wind shielding portion 6a and the rectifying portion 6b are formed. Instead of this, the partition plate 6 may be composed of two plate members, a wind shield plate and a current plate.

In the above-described embodiment, the rectifying unit is formed with the plurality of holes 61, but is not limited to this configuration as long as the conditioned air can pass while receiving the ventilation resistance. For example, the rectifying unit may have a configuration in which a plurality of slits are formed side by side. At this time, it is desirable that the plurality of slits have a uniform arrangement because the flow rate of the conditioned air is more uniform. Alternatively, the rectifying unit may have a configuration in which a plurality of plates are arranged with a gap therebetween.

In the above-described embodiment, the partition plate 6 is a metal flat plate. However, as long as it has a function as a partition member, at least one of the wind shielding portion 6a or the rectifying portion 6b may be a plate member other than metal. Moreover, you may apply a sheet | seat member to at least one of the wind-shielding part 6a or the rectification | straightening part 6b instead of the division board 6. FIG. For example, a vinyl sheet in which holes or slits are formed in the rectifying unit 6b may be applied as the partition member.

In the above-described embodiment, the partition plate 6 is fixed to the container 3. Instead of this, the partition plate 6 may be configured to be movable with respect to the container 3. For example, the partition plate 6 may be attached to a rail portion installed in the container 3, and the partition plate 6 may be movable in the depth direction along the rail portion. If it is this structure, since the volume of 30 A of storage chambers can be changed, the amount which can accommodate the temperature control object 10 can be changed arbitrarily.

In the above-mentioned embodiment, although the temperature control storage apparatus 1 was provided with the wind direction adjustment board, the structure which is not provided with a wind direction adjustment board may be sufficient. Even in the case where the wind direction adjusting plate is not provided, if the conditioned air blows into the storage chamber 30A, the conditioned air in the storage chamber 30A is sucked by the partition plate 6, so A flow layer can be formed.
