JP, 2005-161488, A

The temperature-controlled storage device of Patent Document 1 has a limit in allowing the conditioned air to flow evenly through the entire contained object, and further improvement in temperature-controlled unevenness is required. Further, when the amount of the contained items is small, the shutter cannot sufficiently close the upper gap of the contained items, and there is a problem that the conditioned air passes through the upper gap and is ventilated. Further, when the space between the stored items becomes large when the stored items are arranged, there is a problem that the amount of the conditioned air that does not contribute to the temperature control of the stored items that is blown through the space increases. That is, the temperature control storage device of Patent Document 1 has a problem in that the temperature control performance is apt to decrease depending on the amount or arrangement of the contained items, and the contained items must be stored in consideration of this, resulting in poor workability. Further, since the work of arranging the shutter is required in the work of accommodating the contained objects, workability is also poor in this respect.

An object of the disclosure is to provide a temperature controlled storage device capable of improving temperature control unevenness and improving workability.

The aspects disclosed in this specification employ different technical means to achieve their respective purposes. The claims and the reference numerals in parentheses in this section are examples showing the correspondence with specific means described in the embodiments described later as one aspect, and limit the technical scope. is not.

One of the disclosed temperature control storage devices includes a housing (3) having a storage chamber (30A) in which a temperature control target (10) is housed, and a blower (21), which is integrated with the housing. Installed in the air conditioner (2) for generating conditioned air that is blown into the storage room by the blower, and a blowout part (23) that blows out the conditioned air blown by the blower toward the storage room and the storage room. A suction part (24) for sucking in the conditioned air and a differential pressure forming chamber (30B) provided between the storage chamber and the suction part, the pressure difference forming chamber (30B) being a negative pressure with respect to the storage chamber. And a partition member (6) for partition formation. The partitioning member has a wind shield (6a) that blocks ventilation of the conditioned air from the ceiling of the storage room to a predetermined height, and a shield that has the same vertical dimension as the height of the temperature-controlled object when the maximum storage amount is stored. A rectifying part (6b), which is provided below the wind part and allows conditioned air to pass from the storage chamber to the differential pressure forming chamber while receiving ventilation resistance, is provided separately from the temperature control object .

According to this disclosure, by forming the differential pressure forming chamber by the partition member, a flow in which the conditioned air is sucked from the storage chamber to the differential pressure forming chamber is formed. Since the partition member has the wind shielding part and the rectifying part, the conditioned air passing through the partition member flows so as to be biased toward the rectifying part side. Due to the flow of the conditioned air that is biased toward the rectifying unit side, the conditioned air can be uniformly ventilated through the space in the storage chamber where the temperature control object can be stored. This can improve temperature control unevenness. In addition, the flow of the conditioned air that is biased toward the rectification unit side is formed regardless of the amount or the arrangement of the temperature adjustment target. Therefore, it is possible to prevent the conditioned air from blowing through the upper portion of the temperature control object. Further, even when the gap between the temperature control target and the temperature control target becomes large, the amount of conditioned air that does not contribute to temperature control can be suppressed by uniform ventilation. That is, it is possible to suppress a decrease in the temperature control performance due to the amount and arrangement of the temperature control target, and thereby improve workability. Further, since it is not necessary to install a shutter or the like in the work of accommodating the temperature controlled object, workability can be improved also in this respect. As described above, it is possible to provide a temperature controlled storage device capable of improving temperature control unevenness and improving workability.

(First embodiment)
The temperature control storage device disclosed is a device that can transport, for example, a temperature control target housed in a storage chamber in a frozen state or a refrigerated state. The temperature controlled storage device is carried on a moving body such as a vehicle, a ship, or an aircraft. At the time of this transportation, the temperature controlled storage device is mounted as a container for transportation. The temperature-controlled objects to be transported include fresh foods such as vegetables, fruits, and meats, various frozen foods transported in a frozen state, and the like. Further, the temperature-controlled object may be a living thing or an article which is not a food but needs to be transported at a predetermined temperature.

In the first embodiment, a temperature controlled storage device 1 capable of controlling the temperature of a temperature controlled object 10 housed in a container 3 for transportation to a predetermined temperature will be described with reference to FIGS. 1 to 4. The vertical direction illustrated in the drawings 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. Further, in each drawing, in order to make the configuration of the temperature controlled storage device easy to understand, the internal parts of the container are shown by solid lines.

The temperature controlled storage device 1 is a box-shaped device in which an air conditioner 2 is integrally assembled in a container 3 which is an example of a housing, and is stored in a ventilation space 30 in the container 3 by the conditioned air produced by the air conditioner 2. The temperature of the temperature control object 10 housed in the chamber 30A is controlled to a predetermined temperature. Here, an example of the temperature control target 10 is a large number of plastic containers or cardboard boxes containing fruits and vegetables such as vegetables and fruits. The platen is an abbreviation for a plastic box having a mesh-like ventilation surface formed on the side surface and the bottom surface and having a configuration in which the mesh surfaces can be fitted and stacked in the vertical direction. Ventilation holes are formed on the side surface and the bottom surface of the cardboard box. Air-conditioned air flowing through the storage room 30A enters and exits the interior of the plastic container and the cardboard box through this ventilation hole.

The air conditioner 2 air-conditions, for example, a refrigeration cycle device, a heat dissipation fan, a blower 21 that drives conditioned air, a blast duct 22 that allows conditioned air to flow toward the storage chamber 30A, and a control device that controls the operation of each device. The device is configured as a unit. The refrigeration cycle device is, for example, a refrigerant circuit configured by annularly connecting an electric compressor, a condenser, an expansion valve, an evaporator 20 and the like, and a refrigerant is circulated by a driving force of the electric compressor. In the air conditioner 2, the refrigeration cycle device, the heat dissipation fan, the blower 21, and the control device are attached to one end of the container 3 in the depth direction, and the blower duct 22 is provided in one of the depth direction with respect to the container 3. Attached to the end and bottom. Hereinafter, one end portion in the depth direction will be referred to as a front portion for convenience of description.

The electric compressor is configured by combining an electric motor and a compression mechanism section. 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 operating state of the refrigeration cycle, and the temperature of the air conditioned by the evaporator 20 is controlled. Controlled. As described above, the blower duct 22 forms an air passage extending vertically in the front part of the container 3 and further extending in the depth direction in the bottom part of the container 3. The blower duct 22 is a member that constitutes an air passage for sucking the air in the storage chamber 30A and returning it to the storage chamber 30A again, and the blower 21 and the evaporator 20 are installed therein.

The heat dissipation 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 the control device. The blower 21 is an electric fan that sucks the air in the storage chamber 30A into the blower duct 22 and blows the air that has passed through the evaporator 20 back into the storage chamber 30A, and the air volume is controlled by the control device.

Further, the control device acquires the cold air temperature from the 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 based on the set temperature that has been set and the cool air temperature acquired from the temperature sensor so that the temperature of the storage chamber 30A maintains the set temperature. For example, the control device performs inverter control of the energization amount of the electric motor based on the set temperature and the cool air temperature to control the rotation speed of the compressor. Further, the control device controls the heat radiation amount of the condenser by controlling the on/off of the power supply to the electric motor of the heat radiation fan according to the operating state of the refrigeration cycle device.

In the ventilation space 30 in the container 3, an outlet 23 for blowing out the conditioned air created by the air conditioner 2 into the ventilation space 30 and a suction port 24 for returning the air in the ventilation space 30 to the air conditioner 2 are opened. .. The air outlet 23 is an air-conditioning air outlet that opens at the downstream end of the blower duct 22, and is located at the lower end of the other end of the ventilation space 30 in the depth direction. Hereinafter, the other end portion in the depth direction will be referred to as a rear portion for convenience of description. Therefore, the air outlet 23 opens at the lower end of the rear portion in the ventilation space 30. The suction port 24 is a suction part through which the conditioned air that has flowed through the storage chamber 30A and the differential pressure forming chamber 30B formed in the ventilation space 30 flows out from the ventilation space 30, and is located at the upper end of the front portion of the ventilation space 30. To do. Therefore, the air outlet 23 and the air inlet 24 have a diagonal positional relationship in the ventilation space 30 and are provided at positions 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 shield portion 6a and a rectifying portion 6b. The partition plate 6 is a plate member formed of a metal material such as aluminum. The partition plate 6 is, for example, a flat plate parallel to the height direction and the width direction. The partition plate 6 is installed 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 so 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, among 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 30A is a chamber defined between the outlet 23 and the differential pressure forming chamber 30B, and the differential pressure forming chamber 30B is partitioned between the storage chamber 30A 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 that of the differential pressure forming chamber 30B.

The partition plate 6 is fixedly installed in the container 3. The partition plate 6 is fixed to a predetermined position by being screwed to a frame portion formed on the ceiling portion, the wall portion and the bottom portion of the ventilation space 30, for example. An inlet portion such as a door is provided on a wall portion of the container 3 that divides the storage chamber 30A so as to carry the temperature control target 10 therein. Therefore, the differential pressure forming chamber 30B has a configuration in which the temperature adjustment target 10 cannot be accommodated.

The wind shield 6a is a region of the partition plate 6 that blocks ventilation of conditioned air. The air blocking portion 6a is configured as a plate portion in which openings such as holes and slits are not formed, and has a structure capable of blocking ventilation of conditioned air. The wind-shielding portion 6a is a portion of the partition plate 6 having a predetermined dimension from the ceiling portion of the ventilation space 30 to a predetermined height below. That is, the wind shield portion 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 of the partition plate 6 that allows ventilation of conditioned air. The rectification part 6b is provided below the wind shield part 6a. The rectifying portion 6b is configured as, for example, a so-called punching metal, which is a metal plate having a plurality of holes 61 formed therein. The plurality of holes 61 are formed over the entire rectifying portion 6b. In FIG. 1, the plurality of holes 61 are shown as circular through holes, but the shape is not limited, and the holes 61 may be polygonal through holes, for example. The plurality of holes 61 are formed, for example, so that the number and size per unit area of the rectifying unit 6b are constant. In other words, the plurality of holes 61 are formed in the entire region of the rectifying portion 6b without any deviation. The conditioned air passing through the rectifying unit 6b passes through the plurality of holes 61 from the storage chamber 30A and flows into the differential pressure forming chamber 30B. A portion of the rectifying portion 6b where the plurality of holes 61 are not formed is a resistance portion 62 that provides ventilation resistance to the conditioned air passing through the rectifying portion 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 section 6b is equal to the maximum height in which the temperature-controlled object 10 can be accommodated. That is, the suitable maximum storage amount of the temperature control target 10 is determined by the vertical dimension of the rectifying unit 6b. The vertical dimension of the rectification unit 6b is determined, for example, in consideration of workability in accommodation work of the temperature control target 10. Alternatively, the maximum storage amount of the temperature control object 10 may be determined from the weight that can be stored in the temperature control storage device 1, and the vertical dimension of the rectifying unit 6b may be determined from this maximum storage amount.

The rectification unit 6b has an aperture ratio of 0.5% to 30%. Here, the opening ratio is the ratio of the opening area of the plurality of holes 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 wind direction guide members that guide the wind direction of the conditioned air blown from the air outlet. In the following, the first guide plate 5a and the second guide plate 5b may be simply referred to as a guide plate unless it is necessary to distinguish them. The guide plate is a rectangular plate having a width-direction length that is equal to or larger 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 outlet 23. The angle of the guide plate is set so that the direction of the conditioned air blown from the air outlet is directed to the front of the storage chamber 30A. In the temperature controlled storage device 1, two guide plates, a first guide plate 5a and a second guide plate 5b, are vertically arranged.

The first guide plate 5a is a guide plate provided below the second guide plate 5b, and guides a 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 rest of the conditioned air passes when it blows through to 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 and the air volume of the conditioned air guided by the second guide plate 5b become equal.

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 first guide plate 5a and the second guide plate 5b are respectively installed at heights at which the conditioned air branched by these two guide plates is guided at equal intervals with respect to the height of the rectifying section 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. This makes it easier to form a layer of the conditioned air flow in the height region of the rectifying unit 6b, which will be described later. Further, three or more guide plates may be installed in the vertical direction. The larger the number of the guide plates installed in the vertical direction, the easier it is to form a layer of the flow of conditioned air with respect to the rectifying unit 6b.

The guide plate may be configured so that the vertical angle can be changed. That is, by adjusting the angle of the guide plate, the blowing angle of the conditioned air may be adjusted to a desired angle at the site of luggage loading or at the shipping stage or delivery stage of the temperature controlled storage device 1. Further, the height of the guide plate may be changeable by a configuration in which the guide plate is installed slidably in the vertical direction by a rail or the like. With such a configuration, the direction of the conditioned air can be adjusted in order to form a flow of the conditioned air that can more efficiently adjust the temperature of the conditioned air by disposing the temperature control target 10.

Next, the flow of the conditioned air that passes through the ventilation space 30 will be described with reference to FIGS. 2 and 3. When the air conditioner 2 operates, the blower 21 starts blowing air. Due to 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 by the blower 21 and blown into the space from the blower 21 through the blower duct 22 to reach the partition plate 6, so that the partition plate 6 The section from the fan to the blower 21 has a negative pressure with respect 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 air 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. It can be paraphrased as. 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 by the guide plates 5a and 5b in the direction of the rectifying unit 6b. Due to the pressure difference between the pressure difference 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 dispersed and sucked into all of the plurality of holes 61 formed in the rectifying section 6b. Further, the conditioned air that flows 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 that flows through the height region of the wind shield 6a flows through the inside of the storage chamber 30A so as to be guided to the rectifying unit 6b by the wind shield 6a. Therefore, in the storage chamber 30A, the conditioned air flows over the entire vertical region in which the rectifying section 6b is formed. That is, due to the air-shielding portion 6a and the rectifying portion 6b formed on the partition plate 6, the conditioned air flowing through the storage chamber 30A flows toward the rectifying portion 6b side. In other words, in the storage chamber 30A, a layer of the conditioned air flow is formed in the height region of the rectifying section 6b.

As described above, the layer of the flow of the conditioned air formed in the storage chamber 30A is due to the negative pressure formed in the differential pressure forming chamber 30B by the partition plate 6, and it depends on the amount and arrangement of the temperature control target 10. It is formed regardless. 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 that blows through this gap becomes dominant, and Air-conditioning air flows evenly. As described above, even if the amount or arrangement of the temperature control objects 10 is appropriately changed, the conditioned air is uniformly ventilated to all the temperature control objects 10 housed in the storage chamber 30A. That is, the temperature control unevenness of the temperature control target 10 can be improved.

As shown in FIG. 4, the temperature control target 10 stored in the storage chamber 30A may be stored with its height exceeding the height of the rectifying section 6b. The flow of the conditioned air in the storage room 30A is a flow that is biased toward the rectifying unit 6b side, but a part of the conditioned air is passed through a region higher than the height of the rectifying unit 6b, that is, the height region of the wind shielding unit 6a. After that, a flow that is sucked into the hole 61 above the rectifying portion 6b is formed. Therefore, even if the temperature control objects 10 are stacked higher than the height of the rectification unit 6b, the air conditioning air is ventilated to all the temperature control objects 10 by this partial flow of the air conditioning air. be able to.

The conditioned air that ventilates the inside of the storage chamber 30A controls the temperature of the temperature control target 10 housed in the storage chamber 30A to a predetermined temperature. Since the partition plate 6 forms a uniform conditioned air flow in the storage room 30A, the conditioned air passes through all the temperature control objects 10 accommodated in the storage room 30A. Therefore, the temperature of the temperature controlled object 10 is controlled evenly.

Next, the function and effect of the temperature controlled storage device 1 of the first embodiment will be described. The temperature controlled storage device 1 is installed integrally with the container 3 having the storage chamber 30A in which the temperature controlled object 10 is housed, and is integrally installed in the container 3 to generate conditioned air that is blown into the storage chamber 30A by the blower 21. And an air conditioner 2. The temperature controlled storage device 1 includes a blowout port 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 via the blowout port 23 and the storage chamber 30A and that sucks in the 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 a negative pressure 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-shielding portion 6a and the wind-shielding portion 6a that blocks the ventilation of the conditioned air from the ceiling of the storage chamber 30A to a predetermined height, and the conditioned air is generated from the storage chamber 30A in the differential pressure forming chamber. 30B and the rectification|straightening part 6b which can pass, receiving a ventilation resistance.

According to this temperature controlled storage device 1, by forming the differential pressure forming chamber 30B by the partition plate 6, a flow in which conditioned air is sucked from the storage chamber 30A to the differential pressure forming chamber 30B is formed. Since the partition plate 6 has the wind shielding part 6a and the rectifying part 6b, the conditioned air passing through the partition plate 6 flows toward the rectifying part 6b side. Due to the flow of the conditioned air that is biased to the side of the rectifying unit 6b, the conditioned air can be uniformly ventilated in the space in the storage chamber 30A in which the temperature control target 10 can be stored. This can improve temperature control unevenness. Further, the flow of the conditioned air that is biased toward the rectifying unit 6b is formed regardless of the amount or the arrangement of the temperature adjustment target 10. Therefore, it is possible to prevent the conditioned air from blowing through the upper portion of the temperature control target 10 or between the temperature control target 10 and the temperature control target 10. That is, it is possible to suppress deterioration of the temperature control performance due to the amount and arrangement of the temperature control target 10, and thereby improve workability. Further, since it is not necessary to install a shutter or the like in the work of accommodating the temperature controlled object 10, workability can be improved also in this respect. As described above, it is possible to provide the temperature controlled storage device 1 capable of improving the temperature control unevenness and improving the workability.

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

The partition plate 6 is a plate-shaped member that integrally includes a wind shield 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 part 6a and the rectifying part 6b are separately installed.

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

The temperature controlled storage device 1 has a plurality of vertical guide plates for guiding the conditioned air blown into the storage chamber 30A. According to this, the flow of the conditioned air blown into the storage chamber 30A can be adjusted so as to be distributed in the vertical direction, so that the layer of the conditioned air flow by the rectifying unit 6b can be more easily formed.

The temperature controlled storage device 1 is carried by at least one of a vehicle, a ship, and an aircraft. According to this, the temperature controlled storage device 1 can be applied to a container for transportation that is transported by at least one moving body such as a vehicle, a ship, and an aircraft. Since the container for transportation accommodates the temperature control object 10 for a relatively long period, it is highly necessary to control the temperature control object 10 uniformly without temperature unevenness. Therefore, by applying the temperature control storage device 1 to such a container, the effect of improving temperature control unevenness is great.

The air outlet 23 is located at the upper end of the other end in the depth direction in the ventilation space 30. That is, the air outlet 23 opens at the upper end of the rear portion in the ventilation space 30. The suction port 24 is located at the lower end of the front portion of the storage chamber 30A. That is, the conditioned air is blown from the upper end of the rear portion of the storage chamber 30A, is sucked into the rectifying portion 6b by the differential pressure formed in the differential pressure forming chamber 30B, and is sucked 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 controlled storage device 1 according to 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 in the portion of the storage chamber 30A where the temperature controlled object 10 can be stored, and the same effect as that of the temperature controlled storage device 1 of the first embodiment can be obtained. ..

(Third Embodiment)
A third embodiment will be described with reference to FIG. In the third embodiment, the components denoted by the same reference numerals as those in the drawings according to the first embodiment and the configurations not described are the same as those in the first embodiment, and have the same operational effects. In the third embodiment, only parts different from the first embodiment will be described.

In the temperature controlled storage device 1 according to the third embodiment, the blower duct 222 forms an air passage extending in the depth direction at the ceiling of the container 3. The air outlet 23 is located at the upper end of the other end in the depth direction in the ventilation space 30 as in the temperature controlled storage device of the second embodiment. That is, the air outlet 23 opens at the upper end of the rear portion in the ventilation space 30. The suction port 24 is located at the upper end of the front portion of the differential pressure forming chamber 30B. Therefore, the differential pressure forming chamber 30B is located at the front end of the container 3. The blower 21 and the evaporator 20 are disposed inside the blower duct 222, that is, on the ceiling of the container 3. Therefore, in the temperature controlled storage device 1 of the third embodiment, the size of the storage chamber 30A in the depth direction can be set large, and the volume capable of accommodating the temperature controlled object 10 can be increased.

That is, the conditioned air is blown from the upper end of the rear portion of the storage chamber 30A, is sucked into the rectifying portion 6b by the differential pressure formed in the differential pressure forming chamber 30B, and is sucked from the upper end of the front portion of the differential pressure forming chamber 30B. Also in the temperature controlled storage device 1 according to the second embodiment, a negative pressure with respect to the storage chamber 30A can be applied to the differential pressure forming chamber 30B. Therefore, it is possible to ventilate the conditioned air like a layer in a portion of the storage chamber 30A where the temperature controlled object 10 can be housed, and obtain the same effect as the temperature controlled storage device 1 of the above-described embodiment. ..

(Fourth Embodiment)
A fourth embodiment will be described with reference to FIG. In the fourth embodiment, the components denoted by the same reference numerals as those in the drawings according to the above-described embodiment and the components not described are the same as those in the above-described embodiment, and have the same operational effects. In the fourth embodiment, only parts different from the above-described embodiments will be described.

In the temperature controlled storage device 1 of the fourth embodiment, the partition plate 6 is provided with a sealing member 7 that blocks ventilation in the upper part of the rectifying unit 6b. The sealing member 7 can be provided by a flexible sheet member such as a vinyl sheet. The sealing member 7 is fixed to the partition plate 6 so as to be suspended from the lower end of the wind shield 6a, for example. Only the upper end portion of the sealing member 7 is fixed to the partition plate 6. The sealing member 7 can seal a region from the upper end of the rectifying section 6b to a predetermined height so that conditioned air does not flow. That is, the sealing member 7 closes the rectifying portion 6b and blocks passage of the conditioned air through the hole portion 61. The sealing member 7 may have a vertical dimension capable of sealing from the upper end to the lower end of the rectifying portion 6b, that is, from the bottom of the container 3.

As shown in FIG. 7, the sealing member 7 is installed so as to be placed on the temperature control target 10 when the temperature control target 10 is accommodated. When the height of the housed temperature control object 10 is lower than the height of the upper end of the rectifying section 6b, the sealing member 7 is located above the temperature control object 10 from the upper end of the rectifying section 6b as shown in FIG. Block the area up to the height. The region of the rectifying portion 6b that is closed by the sealing member 7 is referred to as an upper region. The sealing member 7 blocks the upper region to prevent conditioned air from passing through the upper region. The sealing member 7 is formed of a flexible sheet member and can be easily placed on the temperature control target 10. Therefore, even if the amount and arrangement of the temperature control target 10 change and the height of the temperature control target 10 changes, the upper region of the rectifying unit 6b can be reliably blocked within the range of the vertical dimension. ..

Next, the function and effect of the temperature controlled storage device 1 according to the fourth embodiment will be described. The temperature controlled storage device 1 has a sealing member 7 that regulates ventilation of conditioned air in the upper region of the rectifying unit 6b. According to this, when the height of the temperature control target object 10 is lower than the upper end of the rectification part 6b, the conditioned air flows between the upper end of the rectification part 6b and the height of the upper part of the temperature control target object 10. Can be blocked. Therefore, a larger amount of conditioned air can be ventilated by the temperature control object 10, and the temperature control performance can be further improved.

(Fifth Embodiment)
The fifth embodiment will be described with reference to FIG. In the fifth embodiment, the components denoted by the same reference numerals as those in the drawings according to the above-described embodiment and the components not described are the same as those in the above-described embodiment, and have the same operational effects. In the fifth embodiment, only parts different from the above-described embodiments will be described.

The temperature controlled storage device 1 of the fifth embodiment has a covering member 8 capable of covering the upper portion of the temperature controlled object 10. The covering member 8 is provided by, for example, a flexible sheet member having a predetermined area. The covering member 8 is installed on the temperature control object 10 in a state where it is not fixed to other members of the temperature control storage device 1. Alternatively, the covering member 8 may be fixed so as to be hung on a predetermined member of the temperature controlled storage device 1, for example, a ceiling portion or a wall portion of the storage chamber 30A. The covering member 8 blocks the ventilation of the conditioned air by covering the upper portion of the temperature control target 10. Therefore, it is possible to prevent the conditioned air from being concentrated and ventilated in the vicinity of the upper portion of the temperature control object 10, and thus it is possible to further improve the temperature control unevenness.

In the above-described embodiment, the plurality of hole portions 61 formed in the rectifying portion 6b have the same number and size throughout, but the number and size are changed depending on the region. Good. For example, the plurality of holes 61 may be formed such that the number of holes is smaller or the size thereof is smaller toward the upper part of the rectifying portion 6b. In other words, the rectification unit 6b may have a structure in which the ventilation resistance increases toward the top. In this configuration, the ventilation amount of the conditioned air becomes smaller toward the upper part of the rectification unit 6b. Therefore, even when a part of the conditioned air flows through a position higher than the rectifying unit 6b, the part of the conditioned air concentrates on the upper part of the rectifying unit 6b and concentrates on the upper part of the temperature-controlled object 10. As a result, it is possible to suppress temperature control unevenness due to ventilation of the conditioned air.

In the above-described embodiment, the partition plate 6 is assumed to be a single plate member on which the wind shield portion 6a and the rectifying portion 6b are formed. Instead of this, the partition plate 6 may be composed of two plate members, that is, 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 ventilation resistance. For example, the rectification 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 be arranged uniformly so that the flow velocity 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.

Although the partition plate 6 is a metal flat plate in the above-described embodiment, at least one of the wind shield part 6a and the rectifying part 6b may be a plate member other than metal as long as it has a function as a partition member. Further, instead of the partition plate 6, a sheet member may be applied to at least one of the wind shield portion 6a and the rectifying portion 6b. For example, a vinyl sheet having holes or slits formed in the rectifying portion 6b may be applied as the partition member.

In the above embodiment, the partition plate 6 is fixed to the container 3. Alternatively, the partition plate 6 may be movable with respect to the container 3. For example, the partition plate 6 may be attached to the rail portion installed in the container 3, and the partition plate 6 may be movable in the depth direction along the rail portion. With this configuration, since the volume of the storage chamber 30A can be changed, the accommodable amount of the temperature control target 10 can be arbitrarily changed.

In the above-described embodiment, the temperature controlled storage device 1 includes the wind direction adjusting plate, but may have a configuration that does not include the air direction adjusting plate. Even if the wind direction adjusting plate is not provided, if the air conditioning air blows out into the storage chamber 30A, the partition plate 6 sucks the air conditioning air in the storage chamber 30A, so that the air conditioning airflow in the height region of the rectifying unit 6b is increased. A flow layer can be formed.
