Description

The present invention relates to a cooling device.

In general, consumers prefer fresher foods such as fruits and vegetables. For this reason, the foodstuffs are stored at a low temperature using a cooling device and the gas composition in the foodstuff storage is adjusted so that the freshness of the foodstuffs such as fruits and vegetables is not deteriorated during the distribution process from the producer to the consumer. The technology is disclosed (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2001-352899

Here, if an attempt is made to maintain the inside of the storage at a low temperature, the moisture in the gas will condense and the humidity inside the storage will be low. For this reason, there is a problem that water is deprived from foodstuffs such as fruits and vegetables and the quality deteriorates.
For example, it is conceivable to install a humidifier in the storage, but in many cases, the high humidity gas discharged from the humidifier is immediately sucked into the cooling device and condensed. Therefore, it may be difficult to increase the humidity in the storage.

Therefore, the present invention provides a cooling device capable of maintaining the inside of the storage at a low temperature and a high humidity, and maintaining the freshness of foodstuffs such as fruits and vegetables.

In order to solve the above problems, the cooling device according to the present invention is provided in a housing, a gas intake port provided in the housing, a gas intake port for taking in gas, and a gas intake port provided in the housing. A fan that blows the gas from the outside to the inside, a humidifying / cooling unit that is provided inside the housing to humidify and cool the gas, and a humidifying / cooling unit that is provided in the housing and uses the gas in the housing. It is characterized by having an outlet for discharging to the outside of the gas.

With this configuration, the humidified and cooled gas can be discharged from the outlet of the cooling device itself. Therefore, the inside of the storage can be maintained at a low temperature and a high humidity, and the freshness of foodstuffs such as fruits and vegetables can be maintained.
Further, since the gas is taken into the housing from the gas intake port by the fan, the wind hits the fan itself, and the cooling effect of the fan can be enhanced. As a result, it is possible to suppress a decrease in drive efficiency due to heat generation of the fan, and it is possible to efficiently take in gas into the housing. In addition, the gas taken into the storage is not heated without being affected by the heat generated by the fan, preventing a decrease in relative humidity and making it possible to obtain an efficient high-humidity gas.
Further, since the gas is taken into the housing, the inside of the housing can be made positive pressure. Therefore, it is possible to bring the gas into contact with water evenly to obtain a high humidity gas.

In the above configuration, a humidity adjusting unit for adjusting the humidity of the gas discharged from the housing to the outside may be provided in the vicinity of the outlet.

With this configuration, the gas maintained at a desired humidity can be discharged from the cooling device by discharging the gas from the outlet through the humidity adjusting unit.

In the above configuration, the humidity adjusting unit may be a moisture absorbing and holding member capable of holding water.

With this configuration, the humidity control unit can have a simple structure. Therefore, the manufacturing cost of the cooling device can be further reduced. Further, since the outlet provided with the humidity adjusting unit is located between the fan and the deflection unit and is arranged close to the humidifying / cooling unit, water is generated from the high humidity gas of the humidifying / cooling unit by using the moisture absorbing / cooling member. Easy to hold. Therefore, it is possible to easily maintain the humidity of the humidity adjusting unit while having a simple structure.

In the above configuration, a position is provided inside the housing and at a position facing the fan in the first blowing direction of the gas blown from the fan, and the wind direction of the gas intersects the first blowing direction. (2) The gas flowing in the second blowing direction may be discharged to the outside of the housing through the outlet, which is provided with a deflection portion that changes in the blowing direction.

With this configuration, the first blowing direction of the gas and the second blowing direction of the gas by the fan intersect, so that the first blowing direction and the second blowing direction are the same direction. Compared with, the gas passage can be miniaturized. As a result, the cooling device can be miniaturized.
Further, by providing the deflection portion, it is easy for gas to hit the deflection portion and increase the air pressure inside the housing (it is easy to make the inside of the housing positive pressure). Therefore, it is possible to bring the gas into contact with water evenly to obtain a high humidity gas.

In the above configuration, the housing has a rectangular parallelepiped box shape, the gas intake port is provided on one surface of the housing, and the other surface has a direction intersecting the surface direction of the one surface of the housing as a surface direction. In addition, the outlet may be provided between the fan and the deflection portion.

With this configuration, it is possible to efficiently change the direction of the gas wind while making the gas flow path in the housing the shortest path. Therefore, the housing can be miniaturized.

In the above configuration, the deflection portion may be a plate-shaped member whose plane direction is a direction intersecting with the first ventilation direction.

With this configuration, the wind direction of the gas by the fan can be changed with a simple structure. Therefore, the manufacturing cost of the cooling device can be reduced.

In the above configuration, the gas intake port may be arranged below the humidifying / cooling section, and the outlet may be located above the humidifying / cooling section.

With this configuration, the variation of the cooling device can be increased.

In the above configuration, the humidifying / cooling unit is provided so that the gas can pass through, and water is sprinkled on the cooling unit for cooling the gas and the cooling unit to bring the gas and water into contact with each other through the cooling unit. It may be provided with a part.

With this configuration, the gas can be efficiently humidified and cooled.

In the above configuration, a water storage tank provided below the humidifying / cooling unit and capable of storing water is provided, and the water storage tank and the water sprinkling unit are provided via a pump that pumps water from the water storage tank to the water sprinkling unit. May be connected.

Here, when the water sprinkled by the sprinkler section passes through the cooling section, it is cooled, and the cooled water is stored in the tank. Further, since the water stored in the tank is pumped up and supplied to the sprinkler section, the temperature of the water sprinkled from the sprinkler section can be made almost the same as the cooling temperature by the cooling section. As a result, the load on the cooling unit can be reduced, so that a highly efficient cooling device can be obtained.

In the above configuration, the size of the opening area of the outlet may be set so that the air pressure inside the housing is higher than the air pressure outside the housing across the air outlet.

Here, in the cooling device, the gas easily passes through a portion having a low resistance from the fan to the outlet, and a so-called gas shortcut path is likely to occur. If such a shortcut path occurs, the gas may not be sufficiently brought into contact with water. However, by setting the size of the air outlet so that the air pressure inside the housing is higher (positive pressure) than the air pressure outside the housing across the air outlet, the air pressure inside the cooling device is set. The gas can be sufficiently contacted with water without creating a shortcut path for the gas. Therefore, it is possible to obtain a gas having a higher humidity.

According to the present invention, the humidified and cooled gas can be discharged from the outlet of the cooling device itself. Therefore, the inside of the storage can be maintained at a low temperature and a high humidity, and the freshness of foodstuffs such as fruits and vegetables can be maintained.

[First Embodiment]
(Cooling system)
FIG. 1 is a schematic configuration diagram of the cooling device 1 according to the first embodiment.
The cooling device 1 is provided in a storage H for storing foodstuffs such as fruits and vegetables, and is for maintaining the inside of the storage H at low temperature and high humidity.
As shown in FIG. 1, the cooling device 1 includes a housing 2, fans 3a and 3b provided in the housing 2, a deflecting portion 6 provided in the housing 2, and a fan 3a in the housing 2. , 3b and the humidifying / cooling unit 20 provided between the deflection unit 6 and the tank 7 provided on the side of the housing 2 opposite to the humidifying / cooling unit 20 of the deflection unit 6, and the housing 2 will be described later. The main configuration is the humidity adjusting portions 8a and 8b provided on the side plate 2c.
In the following description, the vertical direction of the cooling device 1 will be referred to simply as the vertical direction, and the direction orthogonal to the vertical direction will be referred to as the horizontal direction in a state where the housing 2 is installed on the floor surface F of the storage H. .. Further, in FIG. 1, in order to make the explanation easy to understand, the scale of each part is appropriately changed and shown.

The housing 2 is formed in the shape of a rectangular parallelepiped box. That is, the housing 2 connects the bottom plate 2a in contact with the floor surface F, the top plate 2b facing the bottom plate 2a in the vertical direction, and the bottom plate 2a and the top plate 2b, and the surface directions of the bottom plate 2a and the top plate 2b. It is provided with four side plates 2c whose plane direction is orthogonal to the above. A plurality of air intake ports (corresponding to gas intake ports in the claims) 9 (for example, two in the first embodiment) are formed on the top plate 2b. The air intake port 9 may be provided with, for example, a mesh plate (not shown) for preventing dust or the like from entering the housing 2. Further, of the four side plates 2c, two side plates 2c facing each other in the horizontal direction are each formed with an outlet 15.

The fans 3a and 3b are arranged inside the air intake port 9 in the radial direction. For example, two fans 3a and 3b are provided so as to correspond to the number of air intake ports 9.
The fans 3a and 3b take in air (gas) outside the housing 2 into the housing 2 (see arrow Y1 in FIG. 1). The air blowing direction of the air (hereinafter referred to as cooling air) by the fans 3a and 3b is along the vertical direction.

The humidifying / cooling unit 20 is arranged directly below the fans 3a and 3b. The humidifying / cooling unit 20 humidifies and cools the cooling air (details will be described later). The humidifying / cooling unit 20 includes a watering unit 4 arranged directly under the fans 3a and 3b, and a cooling unit 5 arranged directly under the watering unit 4.

The watering unit 4 sprinkles water downward. The watering section 4 includes a pipe 10 through which the water W flows, and a plurality of nozzles 10a provided in the middle of the pipe 10. The pipe 10 is provided so that the cooling air can pass through. The water W flowing through the pipe 10 is sprinkled downward through each nozzle 10a.

The cooling unit 5 includes a cooling unit main body 11 arranged inside the housing 2 and a refrigerator 12 provided outside the housing 2 and connected to the cooling unit main body 11. The cooling unit main body 11 is formed so as to have a plate shape as a whole by routing a pipe 11a through which a refrigerant (not shown) flows while bending it.
As the pipe 11a, it is preferable to use a member having good heat transfer efficiency. As the pipe 11a, for example, a copper pipe is used. Water W sprinkled from the sprinkling section 4 falls on the cooling section main body 11. The nozzle 10a of the sprinkling unit 4 is arranged so that the water W falls on the entire cooling unit main body 11.

A predetermined gap is formed between the routed pipes 11a. The water W sprinkled from the sprinkler portion 4 drips downward through this gap, and the cooling air also passes through the gap.
The refrigerator 12 cools the refrigerant flowing through the pipe 11a of the cooling unit main body 11 and circulates the refrigerant in the pipe 11a. As a result, the pipe 11a of the cooling unit main body 11 is cooled.

The deflection unit 6 is arranged directly below the cooling unit main body 11 and substantially in the center of the housing 2 in the vertical direction. In other words, the deflection unit 6 is arranged so as to face the fans 3a and 3b in the vertical direction of cooling air blowing (hereinafter referred to as the first blowing direction). The sprinkling unit 4 and the cooling unit 5 are arranged between the fans 3a and 3b and the deflection unit 6.

The deflection unit 6 changes the cooling air from the first air blowing direction to the second air blowing direction (horizontal direction, see arrow Y2) orthogonal to the first air blowing direction. The deflecting portion 6 is made of a metal plate having a high rust preventive effect such as stainless steel. The deflection portion 6 is formed to be inclined so as to gradually extend upward from the horizontal center of the housing 2 toward the side plate 2c of the housing 2. In other words, the deflection portion 6 is formed so as to be inclined so that the direction substantially orthogonal to the first ventilation direction is the surface direction. The outlet 15 is arranged at a position corresponding to the side plate 2c directly above the deflecting portion 6 formed in this way, that is, at a position corresponding to the cooling portion main body 11 of the side plate 2c. The outlet 15 is connected to the horizontal end of the deflection portion 6. The cooling air changed in the second blowing direction by the deflecting portion 6 is discharged to the outside of the housing 2 through the outlet 15.

It can be said that the deflecting portion 6 has a water gradient due to the inclined formation. That is, when the water W sprinkled from the sprinkling section 4 drips downward through the cooling section main body 11, the water W is guided to substantially the center of the deflection section 6 in the horizontal direction by the water gradient.
A drain pipe (corresponding to the drain portion in the claims) 16 is provided at substantially the center of the deflection portion 6 in the horizontal direction. The drain pipe 16 extends in the vertical direction. Water W drips downward through the drain pipe 16.

The tank 7 is arranged on the bottom plate 2a of the housing 2. The upper part of the tank 7 is connected to the lower end of the drain pipe 16. The water W dripping downward through the drain pipe 16 is stored in the tank 7.

The tank 7 and the pipe 10 of the watering portion 4 are connected via a pumping pipe 13. In the middle of the pumping pipe 13, a pump 14 for pumping the water W stored in the tank 7 to the pipe 10 of the watering section 4 is provided. As a result, the water W is circulated between the pipe 10 of the sprinkler portion 4 and the tank 7.

Humidity adjusting portions 8a and 8b are provided so as to close the outlet 15 formed on the side plate 2c of the housing 2. The humidity adjusting units 8a and 8b adjust the humidity of the cooling air discharged through the outlet 15 (details will be described later).
The humidity adjusting units 8a and 8b are, for example, porous hygroscopic holding members having hygroscopicity. Water is retained in the voids in the humidity control units 8a and 8b. Further, the humidity adjusting units 8a and 8b also have a role of removing (separating) the moisture when the discharged cooling air contains excess moisture.

(Operation of cooling device)
Next, the operation of the cooling device 1 will be described.
After the cooling unit main body 11 of the cooling unit 5 is sufficiently cooled, water W is sprinkled from the watering unit 4. In this state, the fans 3a and 3b are driven. Then, the air outside the housing 2 is taken into the housing 2 as cooling air by the fans 3a and 3b through the air intake port 9 (see Y1 in FIG. 1). At this time, the cooling air also hits the fans 3a and 3b themselves.

The cooling air flows in the first air blowing direction. Then, the cooling air flows to the deflection portion 6 through the pipe 10 of the watering portion 4 and the pipe 11a of the cooling portion main body 11. When the water W sprinkled from the sprinkler unit 4 and the cooling air come into contact with each other, the cooling air has a high humidity. The cooling air is cooled by passing the cooling air through the cooling unit main body 11. By being cooled by the cooling unit main body 11, the moisture of the cooling air is slightly condensed, but since sufficient water W is sprinkled from the sprinkling unit 4, the high humidity of the cooling air is maintained.

The direction of the cooling air flowing to the deflecting portion 6 is changed to the second blowing direction when the cooling air hits the deflecting portion 6. Then, the cooling air is discharged to the outside of the housing 2 via the humidity adjusting units 8a and 8b. Since the outlet 15 provided with the humidity adjusting portions 8a and 8b is connected to the horizontal end portion of the deflection portion 6, the outlet 15 can be smoothly outside the housing 2 via the deflection portion 6 and the humidity adjusting portions 8a and 8b. Cooling air is discharged.

Here, since water is held in the humidity adjusting units 8a and 8b, when the cooling air does not maintain the desired humidity, the cooling air passes through the humidity adjusting units 8a and 8b, so that the cooling air passes through the humidity adjusting units 8a and 8b. Is in contact with water, and cooling air is discharged to the outside of the housing 2 at a desired humidity (see arrow Y2 in FIG. 1). On the other hand, when the humidity of the cooling air is higher than necessary, when the cooling air passes through the humidity adjusting units 8a and 8b, predetermined moisture is clinging to the humidity adjusting units 8a and 8b and is specified outside the housing 2. The cooling air from which the moisture has been removed (separated) is discharged. As described above, the humidity adjusting units 8a and 8b have both humidifying and dehumidifying functions in order to maintain the cooling air at a desired humidity.

Further, since the humidity adjusting units 8a and 8b are provided at the outlet 15 formed at a position corresponding to the cooling unit main body 11 of the side plate 2c, they are also close to the watering unit 4. Therefore, the humidity adjusting units 8a and 8b hold the predetermined water W when the water W sprinkled from the sprinkling unit 4 falls on the humidity adjusting units 8a and 8b. Further, since the cooling air passes through the porous humidity adjusting portions 8a and 8b, the air pressure in the housing 2 tends to increase due to the resistance when passing through the humidity adjusting portions 8a and 8b. In other words, the pressure inside the housing 2 can be adjusted by the air permeability of the humidity adjusting units 8a and 8b.

The opening area of the air outlet 15 is such that the air pressure outside the housing 2 is higher than the air pressure outside the housing 2 across the air outlet 15 with the humidity adjusting portions 8a and 8b provided (positive). It is set (to be pressure). Therefore, the cooling air is evenly distributed in the housing 2 without forming a shortcut path. As a result, the cooling air is sufficiently brought into contact with the water W and is sufficiently cooled by the cooling unit main body 11 of the cooling unit 5, so that the cooling air is efficiently produced at low temperature and high humidity. Since the cooling air hits the deflection portion 6, the air pressure inside the housing 2 tends to increase without completely depending on the opening area of the outlet 15. For example, the opening area of the outlet 15 is preferably about 80% of the opening area of the air intake port 9. By setting in this way, the air pressure outside the housing 2 can be surely made higher than the air pressure outside the housing 2 with the outlet 15 interposed therebetween in the state where the humidity adjusting units 8a and 8b are provided.

The low temperature and high humidity cooling air is discharged from the outlet 15 of the housing 2, so that the inside of the storage H is maintained in a low temperature and high humidity environment. The humidity in the storage H can be maintained at about 85% or more.

On the other hand, the water W sprinkled from the sprinkling section 4 drips down to the deflection section 6 via the cooling section main body 11 and further drips into the tank 7 via the drain pipe 16. The water W stored in the tank 7 is pumped up by the pump 14 and returned to the pipe 10 of the sprinkler unit 4 again.
Since the water W sprinkled from the sprinkler unit 4 passes through the cooling unit main body 11, it is cooled by the cooling unit main body 11. Therefore, the water W stored in the tank 7 is cooled to the temperature of the cooling unit main body 11 while repeating circulation with the watering unit 4. Specifically, it is cooled to the same temperature as the environmental temperature in the storage H.

As described above, the cooling device 1 in the first embodiment described above includes the fans 3a and 3b provided in the air intake port 9 of the housing 2, the humidifying cooling unit 20 provided in the housing 2, and the housing. It is provided with an outlet 15 provided on the side plate 2c of 2.
Therefore, the cooling air having a low temperature and a high humidity can be discharged from the outlet 15 of the cooling device 1 itself. Therefore, the inside of the storage H can be maintained at a low temperature and a high humidity, and the freshness of foodstuffs such as fruits and vegetables can be maintained. Further, since the cooling air (gas) is taken into the housing 2 from the air intake port 9, the cooling air hits the fans 3a and 3b themselves, and the cooling effect of the fans 3a and 3b can be enhanced. As a result, it is possible to suppress a decrease in drive efficiency due to heat generation of the fans 3a and 3b, and it is possible to efficiently take in gas into the housing. In addition, the air (gas) taken into the storage H is not heated without being affected by the heat generated by the fans 3a and 3b, preventing a decrease in relative humidity and providing an efficient high-humidity cooling air. It becomes possible to do.
Further, since the cooling air is taken into the housing 2, the inside of the housing 2 can be made positive pressure. Therefore, the cooling air can be evenly contacted with the water W to obtain a high humidity cooling air.

Further, the humidifying / cooling unit 20 includes a cooling unit 5 for cooling the cooling air and a watering unit 4 for sprinkling water on the cooling unit 5. Therefore, the cooling air can be efficiently humidified and cooled to generate desired water vapor.

Further, the cooling device 1 includes a deflection unit 6. The outlet 15 is arranged on the side plate 2c of the housing 2 and between the fans 3a and 3b and the deflection portion 6 (position corresponding to the cooling portion 5). By providing the deflecting portion 6, the cooling air abuts on the deflecting portion 6 and the air pressure of the cooling air can be easily increased. Therefore, the cooling air can be evenly contacted with the water W to obtain a high humidity cooling air.
Further, by making the first air blowing direction of the cooling air and the second air blowing direction of the cooling air intersect, the cooling air is compared with the case where the first air blowing direction and the second air blowing direction are the same direction. The path can be miniaturized. As a result, the cooling device 1 can be miniaturized.

Further, by forming the deflection portion 6 with a metal plate inclined so that the direction substantially orthogonal to the first air blowing direction is the surface direction, the air direction of the cooling air by the fans 3a and 3b can be changed with a simple structure. Can be made to. Therefore, the manufacturing cost of the cooling device 1 can be reduced.
Further, the opening area of the outlet 15 is such that the air pressure outside the housing 2 is higher than the air pressure outside the housing 2 across the outlet 15 with the humidity adjusting portions 8a and 8b provided. It is set (to be positive pressure). Therefore, the cooling air can be evenly distributed in the housing 2 without forming a shortcut path. As a result, the cooling air is sufficiently brought into contact with the water W and is sufficiently cooled by the cooling unit main body 11 of the cooling unit 5, so that the cooling air can be efficiently produced at low temperature and high humidity.

Further, the housing 2 is formed in a rectangular parallelepiped box shape. Then, an air intake port 9 is formed on the top plate 2b of the housing 2, and an outlet 15 is formed on the side plate 2c whose surface direction is orthogonal to the surface direction of the top plate 2b. Therefore, the direction of the cooling air can be efficiently changed while the flow path of the cooling air in the housing 2 is the shortest path. Therefore, the housing 2 can be miniaturized.

Further, by providing the humidity adjusting units 8a and 8b in the outlet 15, the cooling air maintained at a desired humidity can be discharged from the cooling device 1.
Further, by using the humidity adjusting portions 8a and 8b as a porous hygroscopic holding member having a hygroscopic property, it is possible to humidify and dehumidify the cooling air with a simple structure. Therefore, the manufacturing cost of the cooling device 1 can be further reduced.
By arranging the humidity adjusting units 8a and 8b close to the sprinkling unit 4, the humidity adjusting units 8a and 8b can easily hold the water W.

Further, the sprinkler portion 4 and the tank 7 are connected via a pump 14. Therefore, the water W sprinkled from the sprinkler unit 4 can be reused after being cooled by the cooling unit main body 11. As a result, the temperature of the water W sprinkled from the sprinkler portion 4 can be lowered as much as possible. Therefore, since the load on the cooling unit 5 can be reduced, the cooling device 1 can be made highly efficient.

In the first embodiment described above, the case where the deflection portion 6 is arranged substantially in the center of the housing 2 in the vertical direction has been described. Further, a case where the outlet 15 is formed at a position corresponding to directly above the deflection portion 6 in the side plate 2c of the housing 2 has been described. However, the position is not limited to this, and the position of the deflection unit 6 can be set to any position as long as it is below the cooling unit main body 11. Further, the outlet 15 can also be arranged at an arbitrary position as long as it is between the fans 3a and 3b and the deflection portion 6. However, it is desirable that it is below the sprinkler portion 4.

Further, in the above-described first embodiment, out of the four side plates 2c, two side plates 2c facing each other in the horizontal direction are formed with outlets 15, and humidity adjusting portions 8a and 8b are provided in the outlets 15, respectively. The case where it is provided has been described. However, the present invention is not limited to this, and the number of outlets 15 may be one or more, and at least one humidity adjusting units 8a and 8b may be provided. Even if a plurality of outlets 15 are provided, the humidity adjusting units 8a and 8b may be provided in at least one of the outlets 15.

Further, in the above-described first embodiment, the case where the housing 2 is formed in the shape of a rectangular parallelepiped box has been described. Then, the case where the air intake port 9 is formed in the top plate 2b of the housing 2 and the outlet 15 is formed in the side plate 2c whose surface direction is orthogonal to the surface direction of the top plate 2b has been described. However, the present invention is not limited to this, and after the wind direction of the air (gas) taken in from the air intake port 9 is changed by the deflection unit 6, the cooling air having the changed wind direction is blown through the outlet 15. It suffices if it can be discharged to the outside of the housing 2. For example, if the flow path of the cooling air can be defined, the air intake port 9 and the air outlet 15 can be arranged in the same plane.

[Second Embodiment]
(Cooling system)
Next, a second embodiment of the present invention will be described with reference to FIG.

The same embodiments as those of the above-described first embodiment are designated by the same reference numerals and the description thereof will be omitted (the same applies to the following embodiments).

The deflection unit 6 in the second embodiment is arranged below the position of the deflection unit 6 in the first embodiment so as to correspond to the position of the outlet 15. As a result, the outlet 15 is connected to the horizontal end of the deflection portion 6. The cooling air changed in the second blowing direction by the deflecting portion 6 is discharged to the outside of the housing 2 through the outlet 15.

Even when the mounting positions of the humidity adjusting units 8a and 8b are changed as in the second embodiment described above, the same effect as that of the first embodiment described above is obtained.

In the first and second embodiments described above, the case where the deflection portion 6 is formed of a metal plate inclined so that the direction substantially orthogonal to the first ventilation direction is the surface direction has been described. However, the shape is not limited to this, and any shape may be used as long as it changes the direction of the cooling air. For example, the deflection portion 6 may be a block body having an uneven surface, and the wind direction may be changed by applying cooling air to the uneven surface.

As shown in FIGS. 3 and 4, the above-described second embodiment and the third embodiment have the same basic configuration. The difference between the second embodiment and the third embodiment described above is that the humidity adjusting units 8a and 8b of the second embodiment and the humidity adjusting unit 308 of the third embodiment are different.

That is, in the third embodiment, the outlet 15 provided with the humidity adjusting portions 8a and 8b is arranged on the side plate 2c orthogonal to the side plate 2c of the housing 2 in the first and second embodiments. The outlet 15 is arranged below the cooling unit main body 11. In other words, the outlet 15 is arranged between the cooling unit main body 11 and the deflection unit 6. The outlet 15 is formed in a rectangular shape that is long in the horizontal direction so as to correspond to the width of the cooling unit main body 11 in the horizontal direction. The humidity adjusting unit 308 is formed in a rectangular shape long in the horizontal direction so as to correspond to the shape of the outlet 15 formed in this way.

Even when the humidity adjusting unit 8 is one and the discharge direction of the cooling air (see Y2 in FIGS. 3 and 4) changes as in the third embodiment described above, the same as the first embodiment described above. It has the same effect.
