Description

Environment Testing Apparatus

The present invention relates to an environmental test apparatus for performing environmental test of a sample.

In an environmental test for confirming operational reliability of a product in various environmental conditions, it is separated by a partition wall as shown in Japanese Laid-Open Patent Publication No. 2002-349914 (hereinafter referred to as Prior Art 1) An environment test apparatus having a test room and an air conditioner communicating with each other through a communication network is used. In the environmental testing apparatus, the air is adjusted to a constant temperature and humidity by a humidifying device, a cooling device, and the like in the air conditioning room, and the adjusted air is supplied to the test room through the upper opening by the blower installed on the uppermost side of the air conditioning room, Is maintained at a constant temperature and humidity.

However, in the environmental test apparatus according to the prior art document 1, the air that has just entered the test chamber through the upper opening becomes an air stream flowing from the top to the bottom in the test chamber, and is sucked in the lower opening.

Therefore, for example, when a plurality of horizontal shelves are vertically installed in a test room and a sample is placed on each shelf (that is, when a plurality of samples are arranged in a vertical direction), the sample placed on the bottom of the shelf The air flow becomes difficult to reach, and the environmental conditions of the sample at the top of the shelf and the sample at the bottom of the shelf are changed. In addition, if the sample on the top of the shelf is heated, the heat will affect the sample on the bottom of the shelf, and the temperature conditions for these samples will also vary.

Further, even in the environmental testing apparatus in which a plurality of samples are arranged in the horizontal direction in the test room and air is supplied from the air-conditioning chamber to the test chamber so that air flows in the direction in which the samples are arranged, Environmental conditions vary. For example, if a sample on the upstream side is heated, the heat of the sample on the downstream side influences the environmental conditions for these samples. If the environmental conditions for the plurality of samples are different from each other, the accuracy of the environmental test is lowered.

Japanese Laid-Open Patent Publication No. 2002-349914

Accordingly, an object of the present invention is to provide an environmental test apparatus capable of reducing non-uniformity of environmental conditions for a sample.

The environmental test apparatus of the present invention is an environmental test apparatus having a test chamber and a private room separated by a partition wall having a first air vent hole and a first air suction hole, wherein, among six or more wall surfaces defining the test chamber, An exhaust duct having a first wall surface excluding a wall and having a second air vent hole for discharging air in a direction perpendicular to a direction in which a plurality of samples arranged in the test chamber are arranged, And a guide duct constituting at least a part of a second wall surface adjacent to the first wall surface excluding the partition wall and guiding air discharged from the first air discharge hole to the discharge duct through the private room .

According to this, the air discharged from the second air discharge hole to the test chamber flows in a direction perpendicular to the direction in which the plurality of samples are arranged. Therefore, it becomes possible to reduce non-uniformity of environmental conditions for the sample.

In the present invention, among the six or more wall surfaces defining the test chamber, a part of the second wall surface or a third wall surface facing the second wall surface is formed, and the third wall surface facing the second wall surface And a suction duct having a second air suction hole formed at a position away from the plurality of samples. Preferably, the suction duct guides the air sucked by the second air suction hole to the first air suction hole. As a result, air discharged from the second air discharge hole to the test chamber flows reliably in a direction perpendicular to the direction in which the plurality of samples are arranged. Therefore, it becomes possible to further reduce the non-uniformity of the environmental conditions for the sample.

In the present invention, it is preferable that the second wall surface is adjacent to both the partition wall and the first wall surface, and the guide duct has, on one side, a plate-like member constituting the second wall surface, And a communication hole formed in one end of the member in the orthogonal direction and facing the other surface of the plate-like member and communicating with the discharge duct, and a through hole projecting from the other surface of the plate- Wherein the first air discharge hole is divided into a first area extending in a direction intersecting the direction of the first air discharge hole and a second area not formed with the communication hole, It is preferable to communicate with the space facing the first region. As a result, the air discharged from the first air discharge hole flows into the discharge duct through the space and the communication hole facing the first area.

Further, in the present invention, it is preferable that at least one deflection plate parallel to the partitioning plate projects from the first region of the plate-like member. Thus, the air discharged from the first air discharge hole can be effectively passed through the discharge duct.

In the present invention, it is preferable that an air blower for discharging air from the first air discharge hole toward the guide duct is provided in the private room. This makes it possible to effectively flow the air from the private room to the guide duct.

Further, the present invention further includes a test tank having an internal space, wherein the test duct is defined by the exhaust duct and the guide duct being installed in the internal space, and the exhaust duct and the guide duct are connected to the test tank It is preferable that it is detachably installed. Thus, even if the exhaust duct and the guide duct constituting a part of the wall of the test chamber are damaged by heat generation or explosion of the sample, for example, it is possible to restore the wall of the test chamber only by exchanging them.

Further, in the present invention, it is preferable that a heat insulating layer is formed around the test tank. This makes it difficult for the environmental conditions for the sample to fluctuate, thereby improving the test accuracy.

According to the environmental test apparatus of the present invention, the air discharged from the second air discharge hole to the test chamber flows in a direction perpendicular to the direction in which the plurality of samples are arranged. This makes it possible to reduce non-uniformity of environmental conditions for the sample.

Hereinafter, an environment test apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. The following drawings are provided by way of example so that those skilled in the art can fully understand the spirit of the present invention. Therefore, the present invention is not limited to the following drawings, but may be embodied in other forms. In addition, like reference numerals designate like elements throughout the specification.

In this case, unless otherwise defined, technical terms and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. In the following description and the accompanying drawings, A description of known functions and configurations that may unnecessarily obscure the description of the present invention will be omitted.

As shown in Figs. 1 to 3, the environmental test apparatus 1 according to one embodiment of the present invention is used in various environmental tests. The environmental test apparatus 1 includes a substantially rectangular parallelepiped-shaped case 2, A test tank 3 having an internal space 3a and a heat insulating door 4 covering an opening of the test tank 3. [

As shown in Figs. 2 and 3, the test tank 3 is arranged to open forward in front of the case 2 (the front side in Fig. 2 and the lower side in Fig. 3). As shown in Fig. 3, the rear portion of the case 2 is a power storage space in which the power supply device 5 is housed. As shown in Figs. 1 and 2, a display portion 8 and an operating portion 9 are provided on the right side of the door 4 of the case 2. The display unit 8 displays temperature and humidity data in the test chamber 10 of the test tank 3 and the like. The operation unit 9 is an operation unit for performing the temperature and humidity setting in the test chamber 10.

The test tank 3 is surrounded by the heat insulating layer 3b with the surrounding wall surface except for the front opening which is opened and closed by the door 4. [ As a result, the temperature and humidity of the inner space 3a are hardly changed. Therefore, the environmental condition for the sample is hardly changed, and the test accuracy is improved. Four through holes 6 are formed in the heat insulating layer 3b on the back side and the rear side of the test tank 3. In these through holes 6, a connector 5a as a connection portion of the power supply device 5 projects forward. The sealant is filled between the through hole 6 and the connector 5a to maintain the airtightness of the test chamber 10.

In the present embodiment, a sample tray 91 of a flat plate shape shown by a chain double-dashed line in Figs. 2 and 3 is accommodated in the test chamber 10. The sample tray 91 includes a plurality of sockets connectable to the secondary battery as the sample 90 and a plurality of sockets connected to the ends of the socket 90 in the direction of insertion into the test chamber 10 (direction from front to back with respect to the test chamber 10) Formed terminals, and a plurality of wires connecting these sockets and terminals. The sample tray 91 is accommodated in the test chamber 10 so that the terminals of the sample tray 91 are connected to the connector 5a and a plurality of samples 90 (secondary batteries) (5) can be electrically connected to each other. This makes it possible to carry out a charge / discharge test of the secondary battery under various environments.

In the test chamber 10, a guide rail (not shown) is provided. In the sample tray 91, three samples 90 are arranged in a direction orthogonal to the direction of insertion into the test chamber 10. At this time, the plurality of samples 90 are arranged in a line in a direction orthogonal to the inserting direction, but are not listed along the inserting direction. By sliding the sample tray 91 along the guide rails in the horizontal insertion direction, the terminals are connected to the connector 5a so that the plurality of samples 90 and the power supply device 5 are electrically connected. The terminal 90 is detached from the connector 5a by pulling the sample tray 91 in the horizontal direction (direction opposite to the inserting direction) along the guide rails so that the sample 90 and the power source device 5 are electrically disconnected . As described above, the electrical connection and the non-connection of the sample 90 and the power source device 5 can be simply performed by simply inserting or removing the sample tray 91 into the test chamber 10. In the present embodiment, it is possible to store four sample trays 91 in which three samples 90 are arranged in the test chamber 10 along the vertical direction.

The test tank 3 is provided with a partition wall 15 and three ducts 21 to 23 for dividing the rectangular space 3a into a lower space 11 and an upper space 16. As shown in Figs. 2 and 3, the partition wall 15 is provided with two air discharge holes (first air discharge holes) 41 at the right end thereof and one air suction hole Air suction holes) 42 are formed. The two air discharge holes 41 are arranged in the front-rear direction as shown in Fig. The air suction holes 42 extend in the front-rear direction.

2, an air heater 32 composed of an electric heater such as a sheath heater, a cooling device 33 (air cleaner) ) And a humidifier 34 for heating the water in the container with a built-in heater to perform humidification. The two blowers 31 are arranged in the back-and-forth direction and face the air discharge holes 41, respectively. That is, one blower 31 is provided for one air discharge hole 41. By installing the blower 31 as described above, it is possible to effectively flow conditioned air in the air conditioning chamber 11 to the guide duct 22 (to be described later). The air introduced into the air conditioning chamber 11 from the air suction hole 42 flows to the right while the temperature and humidity thereof are adjusted by the humidifying device 34, the cooling device 33, and the air heater 32, And is discharged upward from each air discharge hole 41 by two blowers 31 in a state of constant temperature and humidity.

The three ducts 21 to 23 are installed in the upper space 16 and each of the ducts 21 to 23 constitute one of the six wall surfaces of the substantially rectangular parallelepiped test chamber 10. The partition wall 15 constitutes a wall surface on the lower surface side of the test chamber 10. The three ducts 21 to 23 are provided with a discharge duct 21 having an air discharge hole 21a for discharging air into the test chamber 10 and a discharge duct 21 for discharging the air discharged from the two air discharge holes 41 to the discharge duct 21 And a suction duct 23 for guiding the sucked air to the air suction hole 42. The suction duct 23 is provided with an air suction hole 23a for sucking air in the test chamber 10,

As shown in Fig. 2, the discharge duct 21 is provided with a plate-like member having a rectangular planar shape. The four plate-like members are screwed to the test tank 3 with their four sides abutting against the upper plate, the ducts 22 and 23 and the partition wall 15 of the test tank 3. That is, the discharge duct 21 is detachably attached to the test tank 3 by unscrewing the screw. The plate member of the discharge duct 21 is disposed so as to be spaced apart from the rear side of the test tank 3 and constitutes a flow path 21b through which air flows between the rear side of the test tank 3 and the back side. Further, the discharge duct 21 has an air discharge hole (second air discharge hole) 21a, and air in the flow passage 21b is horizontally discharged forward. The surface of the discharge duct 21 facing the door 4 constitutes one of the six walls defining the test chamber 10 (first wall surface).

As shown in Figs. 2 and 3, the guide duct 22 has a plate-shaped member 25 having a rectangular planar shape, and three sides of the plate-shaped member 25 are connected to the upper plate of the test vessel 3, And is screwed to the test tank 3 while being in contact with the partition wall 15. That is, the guide duct 22 is detachably attached to the test tank 3 by unscrewing the screw. The guide duct 22 is arranged such that the plate member 25 is spaced apart from the right wall portion of the test tank 3 and has two air vent holes 41 between the right wall portion and the right wall portion of the test tank 3, And a flow path 22b communicable with the flow path 22b. One surface (the surface facing the suction duct 23) of the guide duct 22 (the plate-like member 25) is one of the six wall surfaces defining the test chamber 10, and the discharge duct 21 And constitutes a wall surface (second wall surface) adjacent to the constituting wall surface.

As shown in Fig. 4 (a), the plate-shaped member 25 is provided with two communication holes 22a at the right end (rear end) in the figure. These communication holes 22a extend along the vertical direction and are arranged along the above direction. These communicating holes 22a are formed in a portion of the plate-shaped member 25 facing the exhaust duct 21 (the oil passage 21b) to communicate the oil passage 22b with the oil passage 21b. A plurality of communication holes 22a are arranged along the vertical direction but two communicating holes 22a are formed in the right end portion (one end portion) of the plate-like member 25, The ball can be composed.

The guide duct 22 further has a partition plate 26 and a deflection plate 27 protruding from the other surface of the plate- 4 (a), the partition plate 26 is extended in the direction crossing the horizontal direction (forward and backward directions), and the plate member 25 is divided into the first region 25a and the second region 25b. The partition plate 26 is inclined at about 45 degrees with respect to the horizontal direction. Two communicating holes 22a are formed in the first region 25a of the plate-shaped member 25. The plate- The deflection plate 27 extends in parallel with the partition plate 26 and is disposed in the first area 25a. Both ends of the partition plate 26 and the deflection plate 27 extend vertically or horizontally to the side adjacent to the plate-shaped member 25. [ The projecting amounts of the partition plate 26 and the deflection plate 27 from the plate-shaped member 25 are the same. Both ends of the biasing plate 27 are disposed between the air discharge holes 41 and between the communication holes 22a.

The guide duct 22 is arranged such that the partition plate 26 and the deflection plate 27 are in contact with the right wall portion of the test tank 3. Thus, the flow path 22b is formed in a space facing the first region 25a. At this time, the flow path 22b is divided into two by the deflection plate 27. [ That is, the front air discharge hole 41 and the upper side communication hole 22a communicate with each other, and the rear air discharge hole 41 and the lower side communication hole 22a communicate with each other. As a result, the air discharged from the air discharge hole 41 can be effectively passed through the discharge duct 21. This is to prevent the air from the two blowers 31 from flowing to the upper communication hole 22a. The air from the blower 31 on the front side is blown into the communication hole 22a on the upper side by the partition plate 26 and the air from the blower 31 on the rear side is blown by the deflector plate 27 into the communication hole 22a so that the air homogenized in the guide duct 22 is supplied to the flow path 21b of the discharge duct 21. [ Therefore, the air discharged from the air discharge hole 21a of the discharge duct 21 flows horizontally in a forward direction in the test chamber 10, and the airflow is in a laminar flow state.

As shown in Figs. 2 and 3, the suction duct 23 has a plate-like member 35 having a rectangular planar shape, and three sides of the plate-like member 35 are connected to the upper plate of the test vessel 3, And is screwed to the test tank 3 while being in contact with the partition wall 15. That is, the suction duct 23 is detachably attached to the test tank 3 by unscrewing the screw. The suction duct 23 is disposed so that the plate member 35 is spaced apart from the left wall portion of the test tank 3 and communicates with the air suction hole 42 with the left wall portion of the test tank 3 A possible flow path 23b is formed. One surface (the surface facing the guide duct 22) of the suction duct 23 (plate-like member 35) is one of the six wall surfaces defining the test chamber 10, and the guide duct 22 And constitutes a wall surface (third wall surface) opposite to the wall surface constituting it.

As shown in Fig. 4 (b), three air suction holes (second air suction holes) 23a are formed on the right end (front end) of the plate-like member 35 in the figure. The suction duct 23 sucks the air in the test chamber 10 from the air suction hole 23a and guides the air to the airtight chamber 11 through the air suction hole 42. [ These air suction holes 23a extend along the vertical direction and are arranged along the corresponding direction. 3, the air suction holes 23a are formed at the ends which are farthest from the discharge duct 21 (the flow path 21b) of the plate-shaped member 35. [ More specifically, the air suction hole 23a is formed at a position away from the sample 90 in the air discharge hole 21a with respect to the anteroposterior direction. As a result, the air discharged from the air discharge hole 21a reliably flows from the rear to the front, that is, in a direction perpendicular to the direction in which the plurality of samples 90 are arranged. Therefore, it becomes possible to further reduce the non-uniformity of the environmental conditions for the sample 90. A plurality of air suction holes 23a are arranged along the vertical direction, but three air suction holes 23a are formed at one end of the plate-like member 35, . ≪ / RTI >

The suction duct 23 further has a partition plate 36 and two deflection plates 37 and 38 protruding from the other surface of the plate-shaped member 35. 4 (b), the partition plate 36 extends in the direction crossing the horizontal direction (forward and backward directions), and the plate member 35 is divided into the first region 35a and the second region 35b. The partition plate 36 is inclined at about 45 degrees with respect to the horizontal direction. Three air suction holes 23a are formed in the first area 35a of the plate-shaped member 35. [ The deflection plates 37 and 38 extend in parallel with the partition plate 36 and are disposed in the first area 35a. Both ends of the partition plate 36 and the deflection plates 37 and 38 extend vertically or horizontally to the side adjacent to the plate-like member 35. The projecting amounts of the partition plate 36 and the deflection plates 37, 38 from the plate-shaped member 35 are the same. One end of each of the deflection plates 37 and 38 is disposed between the air suction holes 23a and the other end is disposed at a position where the air suction hole 42 is divided into three equal parts with respect to the forward and backward directions.

The suction duct 23 is arranged such that the partition plate 36 and the deflection plates 37 and 38 are in contact with the left wall portion of the test tank 3. Thus, the flow path 23b is formed in a space facing the first region 35a. At this time, the flow path 23b is divided into three by the deflection plates 37 and 38. [ That is, each of the three air suction holes 23a communicates with the air suction holes 42 individually, and an equal suction force is generated in each air suction hole 23a. Therefore, the air discharged from the air discharge hole 21a to the test chamber 10 is likely to flow horizontally forward. As a result, the laminar flow state is effectively maintained in the test chamber 10.

Next, the air flow in the test tank 3 of the environmental test apparatus 1 will be described with reference to Figs. 3 and 5. Fig. The environmental test apparatus 1 in the present embodiment has three ducts 21 to 23. Therefore, the air adjusted by the air conditioning chamber 11 and discharged from the air discharge hole 41 by the blower 31 is temporarily accumulated in the flow passage 22b (a space facing the first region 25a). Then, air is uniformly pressurized in the flow path 22b and is supplied to the flow path 21b of the discharge duct 21 from the two communication holes 22a. That is, as shown in Fig. 5, the air discharged upward from the air discharge hole 41 flows obliquely upward in the flow path 22b and flows into the flow path 21b through the communication hole 22a. The air is once accumulated in the flow path 21b so that the air pressure in the air discharge hole 21a of the discharge duct 21 is discharged into the test chamber 10.

The air discharged from the air discharge hole 21a into the test chamber 10 flows between the sample tray 91 housed in the test chamber 10 and between the uppermost sample tray 91 and the upper surface of the test tank 3, And between the sample tray 91 on the lowermost side and the partition wall 15, horizontally from the rear to the front. At this time, the plurality of samples 90 are arranged in the left-right direction (the direction orthogonal to the back-and-forth direction) as shown in Fig. 3, . Then, the air exhausted into the test chamber 10 is sucked into the suction duct 23 from the front air suction hole 23a. Thereafter, the air flows from the flow path 23b to the air conditioning chamber 11 through the air suction hole 42. [

As described above, according to the environmental test apparatus 1 of the present embodiment, the air discharged from the air discharge hole 41 is guided to the discharge duct 21 by the guide duct 22 and discharged from the discharge duct 21 Air flows in a direction perpendicular to the direction in which the sample 90 is arranged (rear-to-front direction) in the test chamber 10. Therefore, the non-uniformity of the environmental conditions for the sample 90 is reduced. Further, since the respective ducts 21 to 23 are only screwed, the ducts 21 to 23 can be easily attached and detached. Therefore, for example, when the charge / discharge test of the secondary battery (sample 90) is carried out, the heat of the sample 90 and the explosion cause the duct 21 23 are damaged, it is possible to easily restore the test chamber 10 only by exchanging these.

The environmental test apparatus 1 according to the present embodiment has an air chamber 11 in the lower space of the test tank 3 and a test chamber 10 in the upper space, A discharge duct 21 and a guide duct 22 are installed so that the air discharged from the test chamber 41 flows forward from the rear of the test chamber 10. However, the positions of the air conditioning chamber 11, the test chamber 10, the discharge duct 21, the guide duct 22 and the like are not limited thereto.

6, the air conditioning chamber 11 is provided in the upper space of the test tank 3, the test chamber 10 is provided in the lower space, and the air is discharged from the air discharge hole 41 at the right end of the air conditioning chamber 11 The exhaust duct 21 and the guide duct 22 can be provided so that air flows forward from the rear of the test chamber 10 (first modification). Specifically, the discharge duct 21 and the guide duct 22 are installed at the same positions as in the above-described embodiment. At this time, the guide duct 22 can be configured so that the partition plate 26 and the deflection plate 27 are inclined in the direction opposite to the above-described embodiment to guide the air from the air discharge hole 41 obliquely downward. Also in this case, the same effects as those of the above-described embodiment can be obtained. At this time, the suction duct 23 is also installed at the same position as the above-described embodiment, and the partition plate 36 and the deflection plates 37 and 38 are inclined in the opposite direction to induce the air from the air suction hole 23a to diagonally upward Can be configured. By doing so, the same effects as those of the above-described embodiment can be obtained.

7, the air conditioning chamber 11 is provided in the right side space of the test tank 3, the test chamber 10 is provided in the left side space, and the air discharge hole 41 at the upper end of the air conditioning chamber 11, The exhaust duct 21 and the guide duct 22 can be installed so that the air discharged from the test chamber 10 flows forward from the rear of the test chamber 10 (second modified example). Specifically, the configuration is almost the same as that in the state in which the test tank 3 of the above-described embodiment is rotated by 90 degrees. Also in this case, the same effects as those of the above-described embodiment can be obtained. In this modification, a plurality of sample trays 91 can be arranged vertically in the transverse direction. At this time, the direction in which the samples 90 are arranged is the vertical direction, but the flow of the air is in the forward and backward directions, so that it is perpendicular to the horizontal direction. In addition, by arranging the suction duct 23 on the left side of the test tank 3, the same effect can be obtained even when the sample tray 91 is in the horizontal position. In this case, a space for communicating the suction duct 23 disposed on the left side with the air conditioning chamber 11 can be provided below the test tank 3.

8, a test chamber 210 is provided in the upper left space of the test chamber 3 and an air discharge hole 241 of the air chamber 211 is provided in the lower right space of the test chamber 3. Further, The exhaust duct 21 and the guide duct 222 can be provided so as to flow forward from the rear of the test chamber 210 (third modified example). The air conditioning chamber 211 in this modified example is a space defined by forming the partition wall 211a in the air conditioning chamber 11 described above. In this space, an air blower, an air heater, a cooling device, a humidification device, and the like are installed. An air suction hole 242 is also provided in the air conditioning chamber 211.

The air discharge hole 241 is provided at the rear side, and the air suction hole 242 is provided at the front side. The guide duct 222 constitutes the rear half of the right side wall surface of the test chamber 210 and the suction duct 223 constitutes the front half of the right side wall surface of the test chamber 210. The guide duct 222 and the suction duct 223 are not provided with a deflection plate and are constituted by plate members 225 and 235 and partition plates 226 and 236.

A communicating hole 222a is formed at the rear end of the guide duct 222 and an air suction hole 223a is formed at the front end of the suction duct 223. Also in this case, air is discharged from the rear of the test chamber 210 toward the front, and the same effects as those of the above-described embodiment can be obtained.

In this configuration, the left side of the partition wall 211a may not become a space. The partition wall 211a may be integral with at least one of the plate-like members 225 and 235. Also in this modified example, the sample 90 and the sample tray 91 are housed in the same manner as in the above-described embodiment. In this modified example, instead of the air conditioning chamber 211, a front space communicated with the air suction hole 242 and a rear space communicated with the air discharge hole 241 are provided extending in the lateral direction in the air conditioning chamber 11 At the same time, it is possible to employ an air chamber 11 provided with a partition wall for communicating these two spaces at the left end portion of the air conditioner 11.

In this case, the air sucked by the air suction hole 242 flows leftward in the front space, then flows rightward in the rear space, and is discharged from the air discharge hole 241. Also in this case, the same effects as those of the above-described embodiment can be obtained.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims.

For example, the heat insulating layer 3b may not be formed around the test tank 3. [ In addition, each of the ducts 21 to 23 may not be detachably attached to the test tank 3. In addition, the guide duct 22 and the suction duct 23 may not be provided with the deflection plates 27, 37, and 38. Also, one or more blowers 31 may be provided. The suction ducts 23 and 223 may not be installed.

In this case, it is preferable that the air suction hole 42 is disposed at a position away from the sample 90 in the air discharge hole 21a of the discharge duct 21 with respect to the direction orthogonal to the direction in which the samples are arranged. Thereby, the flow of the air discharged from the air discharge hole 21a to the test chamber becomes a direction orthogonal to the direction in which the samples are arranged, and the same effect as described above can be obtained. Further, the test chambers 10, 210 may be in the form of a cube. And the test chamber may be a polyhedron defined by a wall surface of seven or more.

In the above-described embodiment and the first to third modified examples, the discharge duct 21 is provided in the rear portion (rear portion) of the test tank 3, but the discharge duct 21 may be provided at any position on the left, right, . That is, the discharge duct 21 can also be provided so as to discharge air in a direction perpendicular to the direction in which the sample 90 is arranged. In this way, the same effect as that described above can be obtained.

The position of the guide duct 22 and the suction duct 23 can be changed. Also, the positions of the guide duct 222 and the suction duct 223 can be changed. In this case, the discharge duct is moved to the guide duct side. The air conditioning equipment (for example, a blower, an air heater, a cooling device, a humidification device, etc.) may be installed in the guide ducts 22 and 222 or the suction ducts 23 and 223 instead of the air conditioning chamber 11 The guide ducts 22 and 222, or the suction ducts 23 and 223 may serve as an air conditioning chamber. In this case, the air conditioning room 11 becomes a simple private room.

The suction duct (23) may not be disposed at a position facing the guide duct (22). For example, the suction duct 23 may be disposed in place of the partition wall 15, and the air duct 23b may be provided with an air conditioning apparatus so that the suction duct 23 may serve as an air conditioning room (separate room). In this case, the plate member 35 of the suction duct 23 serves as a partition wall separating the test chamber 10 from the air conditioning chamber. At this time, it is preferable that the air suction hole 23a is disposed at the front side. Also in this case, the same effects as those of the above-described embodiment can be obtained. The rear side of the door 4 can be used as the guide duct 22 and the suction duct 23.
