Description

  The present invention relates to a temperature control storage device that adjusts the temperature of a stored item stored in a storage space in a housing to a desired temperature, for example, a technique suitable for use in cooling fruits and vegetables.

[Conventional technology]
Refrigeration apparatuses, refrigeration apparatuses, and refrigeration apparatuses are known as temperature control storage apparatuses that adjust the temperature of an item accommodated in an accommodation space in a housing to a desired temperature. In each of these apparatuses, it takes time to adjust the temperature of the stored item stored in the storage space to a desired temperature.
A specific example of the prior art will be described using pre-cooling of fruits and vegetables (vegetables and fruits).

Fruits and vegetables are pre-cooled before shipping. As a typical precooling method, a forced ventilation method, a differential pressure ventilation method, and a vacuum cooling method are known (see Patent Document 1).
(I) The forced ventilation method is a method in which cool air of a refrigerator is blown into the accommodation space, and the accommodation (for example, cardboard containing fruits and vegetables) accommodated in the accommodation space is cooled.
(Ii) In the differential pressure ventilation method, each cardboard containing fruits and vegetables is provided with a vent hole, all the cardboards are stacked and stacked so that the vent holes match, and the top is covered with a shielding sheet. This is a method in which pressure is generated and cold air due to differential pressure is passed through each cardboard.
(Iii) The vacuum cooling method is a method in which the pressure of the accommodation space is lowered to about 5 mmHg to promote moisture evaporation from the fruits and vegetables, and cooling is performed by latent heat of evaporation due to evaporation of moisture.

[Problems of the prior art]
However, the forced ventilation method, differential pressure ventilation method, and vacuum cooling method described above have the following problems.
(I) The forced ventilation method has the merit of being the cheapest among the above three methods, but is a method for cooling the contents by blowing cold air into the accommodation space, and is therefore a general precooling temperature of 0. It takes a long time to cool to -10 ° C.
Further, the cold air blown out from the outlet is unlikely to be circulated by the stored items loaded in the storage space, and temperature unevenness is likely to occur in the storage space.
As a specific example, when a large amount of stored items are put in a refrigerated container using short type containers (sea container and vehicle-mounted container), for example, to cool the stored items to 5 ° C, it is more than a day at a place where it is difficult to cool. Cooling time is required (see graph A in FIG. 4).

(Ii) In the differential pressure ventilation method, in order to cool in a short time, it is necessary to stack all the cardboards so that the respective vent holes coincide with each other. If the vent holes do not match, no differential pressure is generated in the cardboard. In addition, cold air will not pass. For this reason, there is a concern about reliability, and cooling failure may occur.
In addition, there is a problem that the labor for stacking the vent holes in the same manner and the work of covering with the shielding sheet are required, and the labor for stacking becomes large.

(Iii) Although the vacuum cooling method can surely perform cooling in a short time, since vacuuming is performed, the box body needs to be strong and the equipment cost becomes high.
In addition, a separate cold storage for maintaining the low temperature of the cooled material once cooled by the vacuum cooling method is required. For this reason, the vacuum cooling method causes a great cost increase.

[Example 1]
Example 1 is demonstrated based on FIGS.
The refrigerated container is one in which a refrigerator 2 is assembled to a transport container 1 that is insulated for freezing or refrigeration, and is accommodated in an accommodation space (internal space of the accommodation container 1) by the operation of the refrigerator 2. The stored contents α are adjusted to a desired temperature. Note that the transport container 1 corresponds to a housing having a storage space in which the storage object α can be stored, and creates cold air (air conditioning air) that the refrigerator 2 blows into the storage space.

  The transport container 1 is a short-type marine container or an in-vehicle container, and has a substantially rectangular parallelepiped shape that can be transported independently. Below, for convenience of explanation, the door 3 side of the transport container 1 is “rear”, the side away from the door 3 is “front”, the floor side is “lower”, the ceiling side is “upper”, and the door 3 side is viewed from the door 3 side. The description will be made by referring to the right side as “right” and the left side as viewed from the door 3 side as “left”. These directions are for explaining the embodiments and are not limited.

The refrigerator 2 is operated by receiving electric power from a commercial power source or a container power source. The refrigeration cycle, the cold air production duct 4, the condenser fan, the evaporator fan 5, the control device, etc. are unitized to carry containers. 1 is assembled at the front position.
The refrigeration cycle is configured using an electric compressor, a refrigerant condenser (condenser), a pressure reducing device (expansion valve), a refrigerant evaporator 6 (evaporator), and the like.

The electric compressor is configured by combining an electric motor and a refrigerant compressor, and the refrigerant compressor is driven by the electric motor, and the operation state of the refrigeration cycle is controlled mainly by energization control of the electric motor by the control device. And the temperature of the accommodation space is controlled.
The cold air manufacturing duct 4 is an air passage that extends in the vertical direction and is attached to the front portion of the transport container 1. Specifically, the cold air production duct 4 is a passage member that sucks air in the accommodation space and returns it to the accommodation space, and the refrigerant evaporator 6 is disposed therein.

The condenser fan is an electric fan that forcibly exchanges heat between the refrigerant condenser and the outside air (outside air of the transport container 1), and is energized and controlled by the control device.
The evaporator fan 5 is an electric fan that sucks the air in the accommodation space into the cold air production duct 4 and blows out the air (cold air) that has passed through the refrigerant evaporator 6 again into the accommodation space, and is energized and controlled by the control device.

The control device performs energization control of each electric functional component mounted on the refrigerator 2.
Here, the refrigerant evaporator 6 described above corresponds to a heat exchanger that cools the air. In addition, the refrigerator 2 includes a temperature sensor 7 that measures the temperature of the cold air blown into the accommodation space. Further, the refrigerator 2 is provided with temperature setting means that is manually set by the user.
Based on the set temperature set by the temperature setting means and the temperature detected by the temperature sensor 7, the control device controls the energization of the electric motor of the electric compressor and the like so that the temperature of the housing space maintains the set temperature. .

  As a specific example, the control device performs inverter control of the energization amount of the electric motor based on the set temperature and the detected temperature to variably control the rotation speed of the refrigerant compressor. The control device controls the condenser fan on and off according to the operating state of the refrigeration cycle. Further, the control device switches the evaporator fan 5 to a high operation or a low operation according to a fan switch set by a user.

(Feature Technology 1 of Example 1)
In the refrigerated container according to the first embodiment, the air outlet 8 that blows out the cold air produced by the refrigerator 2 into the storage space and the suction port 9 that returns the air in the storage space to the refrigerator 2 are provided via the storage space. Are provided at opposite positions.
The container 1 for conveyance is an example of the case which can be conveyed, and the blower outlet 8 and the suction inlet 9 of this Example 1 are provided in the diagonal position of accommodation space. Thereby, it becomes the positional relationship from which the cold wind which came out from the blower outlet 8 is suck | inhaled by the suction inlet 9 via the accommodation thing (alpha).

  More specifically, as shown in FIGS. 2 and 3A, the air outlet 8 is provided along the lower edge of the rear end of the accommodation space, and the suction port 9 is the upper edge of the front end of the accommodation space. As shown in FIG. 1, the cold air blown out from the blowout port 8 is sucked from the suction port 9 after passing through all the stored items α stored in the storage space.

  Here, an example of the container α is a large number of plastic containers (vegetables such as vegetables and fruits) (a plastic box that can be fitted and stacked in a vertical direction in which a substantially net-like ventilation surface is formed on the side surface and the bottom surface) Numerous placons containing fruits and vegetables are stacked and placed inside the refrigerated container (accommodating space) in a state where they are overlapped in the left, right, front, rear, top and bottom directions.

(Effect 1 of Example 1)
As described above, the refrigerated container according to the first embodiment accommodates the air outlet 8 that blows out the cold air produced by the refrigerator 2 into the accommodation space, and the suction port 9 that returns the air in the accommodation space to the refrigerator 2. It is provided at a position facing through the space.
As a result, the cold air blown out from the outlet 8 passes through all the stored items α stored in the storage space (the fruits and vegetables in all the platens stacked in the storage space) and is sucked into the suction port 9. All the contents α are cooled to a desired temperature in a short time without unevenness.
As described above, the refrigerated container according to the first embodiment employs an inexpensive forced ventilation method, but can cool all the contents α to a desired temperature in a short time without unevenness.

A specific example will be described with reference to the graph of FIG.
In the case of a refrigerated container having a conventional structure in which cold air is blown from the floor surface of the storage space of the refrigerated container, it takes about 26 to 29 hours to cool the stored material α to 5 ° C. in a place where it is difficult to cool. (See graph A in FIG. 4).
On the other hand, while disposing the outlet 8 and the suction port 9 at the opposite positions and providing the outlet 8 and the suction port 9 at diagonal positions in the accommodation space, to cool the contents α to 5 ° C. Even if it is difficult to cool, it can be shortened to about 14 hours (see graph B in FIG. 4).

(Effect 2 of Example 1)
The refrigerated container can be transported. For this reason, it is possible to quickly cool the contents to be transported and to stably maintain the desired temperature.
Moreover, unlike transportation, it can also be used as a movable precooling facility or storage refrigerator. Thereby, a refrigerated container can be conveyed and utilized to the place which requires pre-cooling equipment and a storage, and the operation rate of a refrigerated container can be raised. That is, the cost effectiveness of the refrigerated container can be enhanced.
As described above, the refrigerated container can be transported, and the pre-cooling facility and the storage refrigerator can be moved. Therefore, according to the first embodiment, it is possible to use the refrigerated container at the site of the transport destination and the destination. For this reason, it becomes possible to cool the contents α immediately at the destination.

(Effect 3 of Example 1)
The refrigerated container is provided with the air outlet 8 and the air inlet 9 at diagonal positions in the accommodation space. As a result, a large number of the stored items α stacked in the storage space can be brought to a desired temperature without unevenness in a short time, and uneven cooling of the stored items α can be suppressed.

(Feature Technology 2 of Example 1)
As described above, the refrigerated container of the first embodiment is provided with the air outlet 8 along the lower edge of the rear end of the accommodation space. On the other hand, the refrigerator 2 is unitized and assembled at the front position of the transport container 1.
For this reason, the cold wind guide passage 10 for guiding the cold wind from the cold wind outlet of the cold wind production duct 4 to the outlet 8 at the lower edge of the rear end of the housing space is required.

  Here, a plurality of T-shaped rails 11 are provided in advance on the floor surface of the transport container 1 as shown in FIG. Therefore, in the first embodiment, the cold air guide passage 10 is provided using a plurality of T-shaped rails 11.

Specifically, the T-shaped rail 11 extends in the front-rear direction, and a slit extending in the front-rear direction is provided between the upper surface of the T-shaped rail 11 and the upper surface of the adjacent T-shaped rail 11. . If this slit is a conventional structure, it is used as a cold air blowing slit. However, in this embodiment 1, in order to guide the cold air to the outlet 8 at the lower edge of the rear end of the housing space, there is a blowing slit on the floor surface. Must not exist.
Therefore, in the first embodiment, the upper surface of the plurality of T-shaped rails 11 is covered with a plate material 12 made of aluminum or the like to close the blowing slit, and the space between the plurality of T-shaped rails 11 is used as the cold air guide passage 10.

(Effect 4 of Example 1)
In this way, by laying the plate material 12 on the upper surface of the T-shaped rail 11, it is possible to obtain the cold air guide passage 10 that guides the cold air from the front end (cold air outlet of the cold air production duct 4) to the rear end (air outlet 8). it can.
Thereby, the blower outlet 8 and the suction inlet 9 can be easily arrange | positioned in a diagonal position. That is, the implementation cost of the refrigerated container to which the present invention is applied can be suppressed.

(Feature Technology 3 of Example 1)
The air outlet 8 of the first embodiment is provided with a wind direction control means 13 for adjusting the vertical blowing angle of the cold air blown out.
The air direction control means 13 is provided in substantially the entire range of the air outlet 8 and is attached to the inner surface of the door 3 as shown in FIG. It is aimed at. Of course, the wind direction control means 13 is provided so as not to interfere with the opening and closing of the door 3.

The air direction control means 13 may be fixed and cannot change the angle, or may be capable of arbitrarily adjusting the vertical angle of the cold air blown from the air outlet 8.
Although the angle adjustment mechanism of the wind direction control means 13 is not limited, an example is demonstrated with reference to FIG. The wind direction control means 13 is a rectangular plate, and the wind direction control means 13 according to the first embodiment is divided into a plurality of parts in the left-right direction, and is provided so that the blowing angle can be adjusted at each location in the left-right direction. .

  The lower end of each wind direction control means 13 is assembled to a support plate 15 attached to the inner surface of the door 3 via a hinge 14. On the other hand, angle fixing plates 16 for fixing the angle of the wind direction control means 13 at an arbitrary position are provided at the left and right ends of each wind direction control means 13. The angle fixing plate 16 has a rear end fixed to the support plate 15, and an arcuate slit 16 a is provided in the rotation range of the wind direction control means 13. A screw (bolt or the like) that can be screwed into the left and right ends of the wind direction control means 13 is inserted into the slit 16a. After adjusting the angle of the wind direction control means 13, the screw is tightened. The angle of the wind direction control means 13 is fixed.

(Effect 5 of Example 1)
Thus, by providing the wind direction control means 13 for directing the blowing direction of the cold air toward the suction port 9 at the air outlet 8, the cold air can be blown out toward the contained material α stacked in the accommodation space. The cooling time can be shortened.
Specifically, by providing the wind direction control means 13, it is possible to reduce the content α to about 5 hours even when it is difficult to cool, even when the contents α are cooled to 5 ° C. (FIG. 4). (See graph C).
In the first embodiment, the wind direction control means 13 is fixedly arranged or provided so that the angle can be adjusted. However, the wind direction control means 13 may be provided so as to be swingable by electric drive.

(Feature Technique 4 of Example 1)
The outlet 8 of the first embodiment is provided with a plurality of louvers 17 that adjust the horizontal blowing angle of the cold air blown out.
The louver 17 is provided in substantially the entire range of the air outlet 8. Specifically, as shown in FIG. 7, the louver 17 is provided in the wind direction control means 13, and adjusts the left and right direction of the cold air blown from the outlet 8 to reduce the left and right cooling unevenness. It is to suppress.

  Each louver 17 may be fixed and cannot be changed in angle, or may be capable of arbitrarily adjusting the angle of the cold air in the left-right direction. Of course, the angle adjusting mechanism of the louver 17 is not limited, and can be appropriately adopted.

(Effect 6 of Example 1)
In this way, by providing the louver 17 that adjusts the horizontal blow direction of the cold air blown from the blower outlet 8, it is possible to quickly and uniformly cool all the stored items α stacked in the storage space.
In the first embodiment, the louver 17 is fixedly arranged or provided so as to be adjustable in angle. However, the louver 17 may be provided so as to be swingable by electric drive.

(Feature Technology 5 of Example 1)
In the upper part of the accommodation space (specifically, the ceiling portion of the accommodation space) in the first embodiment, the flexibility that closes the upper gap between the accommodation object α accommodated in the accommodation space and the ceiling of the accommodation space. A shutter 18 made of a film member is attached.
The shutter 18 is made of, for example, a resin having a predetermined thickness (for example, a thick vinyl film), and the left and right width is provided so as to coincide with the left and right width of the accommodation space.
The shutter 18 hangs down from the ceiling on the rear side of the accommodation space. As an example, the lower end of the hanging shutter 18 reaches the floor surface.

  Further, as shown in FIG. 3B, the shutter 18 is provided with a plurality of cut lines 18a (vertical slits) extending in the vertical direction, and the shutter 18 is divided into a plurality of parts in the horizontal direction. Although the number of cuts 18a and the positions where the cuts 18a are provided are not limited, as an example, in the first embodiment, three cuts 18a are provided at equal intervals.

(Effect 7 of Example 1)
Thus, by attaching the flexible shutter 18 to the upper part of the storage space, as shown in FIG. 1, the upper gap between the storage object α stacked in the storage space and the ceiling of the storage space. Can be closed by the shutter 18, and the problem that the cold air passes through the upper gap can be avoided.
Thereby, since the cold wind blown out from the blower outlet 8 can be reliably sucked into the suction inlet 9 via the accommodation thing (alpha), the accommodation object (alpha) can be cooled quickly and reliably.

A specific example will be described with reference to the graph of FIG.
When the shutter 18 is not provided, a part of the cold air blown out from the outlet 8 is sucked into the suction port 9 through the upper gap between the upper part of the storage object α and the ceiling of the storage space. As indicated by the solid line D, it takes time to cool the contents α.
On the other hand, in the first embodiment in which the shutter 18 is provided in the upper part of the accommodation space, the shutter 18 closes the upper gap between the upper part of the accommodation α and the ceiling of the accommodation space, so that the cool air is reliably accommodated without waste. The material α is sucked into the suction port 9 through the object α, and as shown by the solid line E in FIG.

(Effect 8 of Example 1)
In addition, since the slit 18a extending in the vertical direction is provided in the shutter 18 of the first embodiment, the shutter 18 divided by the cut 18a is formed even when a lateral width gap is generated between the storage object α and the side surface of the storage space. The width gap can be closed by a part of the.

A specific example is shown in FIG. When the lateral width of the storage object α loaded in the storage space is narrower than the lateral width of the storage space, the storage object α is stacked so that a lateral width gap does not occur on the left side surface of the storage space. As a result, a lateral width gap is generated between the right end surface of the stacked objects α and the right side surface of the storage space. However, in that state, as shown in FIG. 3C, a part of the shutter 18 divided by the cut line 18a fills the lateral width gap generated on the right side.
In this way, the lateral width gap can be blocked by a part of the shutter 18, and therefore the cooling time delay due to the lateral width gap can be prevented.

(Feature Technology 6 of Example 1)
As described above, the refrigerator 2 according to the first embodiment includes the temperature sensor 7 that detects the temperature of the cold air blown out from the air outlet 8.
Here, in the case of the refrigerator 2 having the conventional structure, the temperature sensor 7 is attached to the inside of the cold air production duct 4 and the temperature of the cold air immediately after passing through the evaporator 6 (the temperature of the cold air blown out from the cold air production duct 4). ) Was detected.

  On the other hand, in this Example 1, the cold air blown out from the cold air production duct 4 passed through the cold air guide passage 10 between the T-shaped rails 11 (a passage extending long in the front-rear direction on the lower surface of the transport container 1). Then, it blows out from the blower outlet 8. For this reason, when the temperature sensor 7 is disposed inside the cold air production duct 4 as in the conventional structure, the temperature actually blown out from the outlet 8 is higher than the outlet temperature detected by the temperature sensor 7, and cooling is performed. The trouble that time becomes long will arise.

  On the other hand, in the first embodiment, the temperature sensor 7 is disposed in the vicinity of the air outlet 8. As a specific example, as shown in FIG. 1, the temperature sensor 7 is disposed in the vicinity of the rear end of the T-shaped rail 11 (the rear end side of the cold air guide passage 10).

(Effect 9 of Example 1)
By providing in this way, the blowout temperature detected by the temperature sensor 7 and the temperature actually blown out from the blowout port 8 can be made substantially coincident with each other, so that cool air suitable for cooling can be blown out from the blowout port 8. It becomes possible. As a result, the problem that the cooling time becomes long can be avoided.

(Feature Technology 7 of Example 1)
In the refrigerated container according to the first embodiment, an inclined member 19 that smoothly changes the flow direction of the cold air is disposed at a corner portion (a location where the cold air rapidly bends) existing in the middle of the cold air passage led to the air outlet 8. Yes.
As a specific example, as shown in FIG. 1, the first embodiment has a curved surface shape at the connection portion between the lower end of the cold air production duct 4 extending in the vertical direction and the cold air guide passage 10 extending in the front-rear direction. An inclined member 19 having an (R shape) is arranged and provided so as to smoothly guide the cold air from the cold air production duct 4 to the cold air guide passage 10.

(Effect 10 of Example 1)
Thus, by providing the curved inclined member 19 at the corner where the cold air is bent sharply, the cold air can be smoothly guided from the cold air production duct 4 to the cold air guide passage 10, and the pressure loss of the cold air is suppressed. Can do. And the reduction of pressure loss can raise the cooling efficiency of the accommodation thing (alpha), and can aim at shortening of cooling time.
The shape of the inclined member 19 is not limited to a curved surface shape, and may be an inclined plate or the like. Of course, the location of the inclined member 19 is not limited. For example, the inclined member 19 is arranged at the exit location of the cold air guide passage 10 (that is, the air outlet 8), so that the cool air blown out from the cold air guide passage 10 is smoothly controlled by the air direction control means 13. You may provide so that it may face.

(Feature Technique 8 of Example 1)
In the first embodiment, a suction port 9 is provided on the back side (front side) of the accommodation space.
Then, the cold air that has passed through the storage object α stacked in the storage space is sucked into the upper suction port 9 through the front gap between the front surface of the storage space and the front surface of the storage object α stacked in the storage space. It is.
For this reason, when the storage object α is pressed against the front surface of the storage space, the front gap is closed, and in particular, the cooling rate of the cooling of the storage object α stacked on the lower side is lowered.

Therefore, in the first embodiment, on the back side (front side) of the storage space, the air passage (front) between the storage object α stored in the storage space and the wall surface on the back side of the storage space (front surface of the storage space). A stopper 20 is provided for ensuring a clearance.
A specific example of the stopper 20 is provided on the floor surface of the accommodation space. The stopper 20 is a member extending in the left-right direction, and the forward movement of the stored object α is prevented when the front end of the stored object α contacts the stopper 20.

  This stopper 20 is fixed to the rear floor surface by a predetermined distance from the front end of the accommodation space. The front gap secured by the stopper 20 is at least 5 cm, preferably 10 cm, and more preferably 20 cm to 30 cm. As an example, in this first embodiment, the front gap is secured by 30 cm by the stopper 20.

(Effect 11 of Example 1)
In the first embodiment, by providing the stopper 20, it is possible to avoid a problem that the front gap is blocked by the storage object α. As a result, the contents α can be reliably cooled quickly, and the reliability of the refrigerated container can be improved.
Further, the stopper 20 has a structure in which a member extending in the left-right direction is attached to the flooring, and the cost can be suppressed. That is, high reliability can be obtained at a low cost.

  The stopper 20 shown in the first embodiment is an example and is not limited. Specifically, the stopper 20 only needs to be able to prevent the contained material α from being pressed against the front surface of the accommodation space and to secure a front gap, for example, a bar, a wire mesh, a lattice or the like extending in the vertical direction. Also good.

[Example 2]
Embodiment 2 will be described with reference to FIG. In the following embodiments, the same reference numerals as those in the first embodiment denote the same functional objects.
In the second embodiment, the wind direction control means 13 is arranged in two stages, and the cold air blowing angle is provided in two stages. Specifically, the wind direction control means 13 of the second embodiment includes a first control plate 13a that directs the cool air blowing direction to an angle lower than the angle toward the suction port 9, and a second control plate 13a that directs the cool air blowing direction to the suction port 9. And a control plate 13b.

(Effect of Example 2)
Thus, by making the wind direction control means 13 in two stages, it is possible to suppress the uneven blow-out of the cold air in the vertical direction, and to suppress the uneven cooling of the contents α.
Specifically, in this embodiment, since the cool air is blown out at a low angle by the first control plate 13a, it is possible to increase the amount of cool air passing through the lowermost stage of the accommodation α. As a result, it is possible to avoid the cooling unevenness of the lowermost package α which is likely to generate the cold air unevenness.

[Example 3]
Embodiment 3 will be described with reference to FIG.
In the first embodiment, the shutter 18 that hangs down from the ceiling is shown. However, the shutter 18 of the third embodiment adopts a roll screen type, and the height from the ceiling to the lower end of the shutter 18 is arbitrarily adjusted. It is possible. During the operation of the evaporator fan 5 (during the operation of the refrigerated container), the lower end of the shutter 18 is pressed against the storage object α by the differential pressure between the upstream side and the downstream side of the shutter 18. Formation of gaps between them (cold air leakage) is avoided.

  As in the first embodiment, the upper gap between the accommodation α and the ceiling can be closed by the shutter 18 of the third embodiment, so that the cooling time delay due to the upper gap can be prevented. In addition, since the roll-up is performed at the time of loading / unloading the stored item α, there is no problem that the shutter 18 interferes with the operation of loading / unloading the stored item α.

Moreover, in the said Example 1, the example which block | closes the lateral width gap produced between the accommodation thing (alpha) and the side surface of the accommodation space with a part of shutter 18 divided | segmented by the cut 18a was shown. On the other hand, the third embodiment uses a movable closing plate 21 that can be opened and closed to close the lateral width gap. The movable blocking plate 21 is attached to the side surface (left side surface in the drawing) of the accommodating space, and opens the movable blocking plate 21 to close the horizontal width gap when a horizontal width gap is generated.
As in the first embodiment, the horizontal gap can be closed by the movable closing plate 21, so that the cooling time can be prevented from being delayed due to the horizontal gap.

However, the present invention is not limited, and the air outlet 8 and the air suction port 9 may be provided on the opposite side of the accommodation space. good.
Further, at least one of the air outlet 8 or the air inlet 9 may be arranged in a plurality of locations so as to further suppress the cooling unevenness.

  In the first embodiment, the wind direction control means 13 is set to one stage and the cold wind blowing angle is set to one stage. In the second embodiment, the wind direction control means 13 is set to two stages and the cold wind blowing angle is set to two stages. The number of stages of the means 13 is not limited to this, and the blowing angle of the cold air may be multistage as three stages, four stages,. The number of stages can be determined by design according to the size of the storage object α, the storage amount, etc., in order to further suppress the cooling unevenness.

  In the above-described embodiment, an example in which the cold air guide passage 10 is formed using the existing T-shaped rail 11 is shown. However, a plate material is provided on a floor surface (such as unevenness extending in the front-rear direction) that does not employ the T-shaped rail 11. 12 may be provided to cover the cold air guide passage 10. Of course, even if the T-shaped rail 11 or the corrugated sheet extending in the front-rear direction does not exist on the floor surface, the cold air guide passage 10 may be provided by forming a space under the plate material 12.

  In the above embodiment, the example of refrigeration was shown as an example of adjusting the temperature of the stored material α stored in the storage space to a desired temperature, but the present invention is not limited to refrigeration, and the stored product α is frozen. The refrigerator 2 may perform the heat pump operation and store the stored contents α.

  In the above embodiment, fruits and vegetables are shown as an example of the contents α, but the contents α are not limited to fruits and vegetables and can be variously changed.

The shutter 18 shown in the above embodiment is an example, and the material , shape, and the like are not limited. That is, the shutter 18 does not need to be made of resin as long as the shutter 18 has a function that allows the cool air to be reliably applied to the object α in the accommodation space. For example, a metal such as paper, wood, and aluminum can be applied. is there.
