[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An exemplary embodiment will now be described in detail with reference to the accompanying drawings.

[0012] The environment creating device 100 creates an environment for testing a test object placed inside the device. In this example, the environment creating device 100 is a thermo-hygrostat that maintains constant temperature and humidity in the internal space. The environment creating device 100 is used, for example, for reliability tests of various semiconductor elements, electronic circuits, etc., and for tests of heat resistance, moisture resistance, etc. of materials.

[0013] The environment forming device 100 includes a housing 1, an inner door 12 disposed in the housing 1, and a cleaner 2. The environment forming device 100 further includes an outer door 13 attached to the housing 1 so as to be able to open and close freely. The outer door 13 is disposed outside the inner door 12. In other words, the environment forming device 100 has a double door structure.

[0014] The housing 1 is, for example, a thermostatic chamber. The housing 1 is formed in a substantially rectangular parallelepiped shape having an internal space. The housing 1 has an opening 1a through which a test object is inserted.

[0015] The inner door 12 is attached to the housing 1 so that the opening 1a can be opened and closed freely. When closed, the inner door 12 blocks the opening 1a and seals the inside of the housing 1. The inner door 12 is an example of a translucent member. A translucent member is a member that has translucency, i.e., allows light to pass through. A user can observe the test object through the inner door 12 from outside the environment creating device 100. In this example, the inner door 12 is made of glass.

[0016] When closed, the outer door 13 covers the inner door 12 and seals the inside of the housing 1. In this example, the outer door 13 is made of, for example, metal.

[0017] The cleaner 2 is a cleaner for the environment creating device. The cleaner 2 is attached to the inner door 12 so as to be slidable in the in-plane direction of the inner door 12. The cleaner 2 slides in the in-plane direction of the inner door 12 during the test, thereby removing water droplets, fogging, frost, dirt, etc. (hereinafter referred to as "water droplets, etc.") that may adhere to at least the inner surface of the inner and outer surfaces of the inner door 12. In this example, the cleaner 2 slides in the in-plane direction of the inner door 12 during the test, thereby removing water droplets, etc. that may adhere to both the inner and outer surfaces of the inner door 12.

[0018] Next, a detailed description will be given of the configuration of the cleaner 2. Figure 2 is a schematic diagram of the inner door 12 and the cleaner 2 as viewed from above the inner door 12.

[0019] The cleaner 2 includes an inner cleaner 3A disposed on the inner surface 12a of the inner door 12, and an opposing member 3B disposed on the outer surface 12b of the inner door 12 and facing the inner cleaner 3A across the inner door 12. The inner cleaner 3A is maintained facing the opposing member 3B by magnetic force. The inner cleaner 3A slides on the inner surface 12a of the inner door 12 as the opposing member 3B slides on the outer surface 12b of the inner door 12.

[0020] FIG. 3 is a perspective view of the inner cleaner 3A. FIG. 4 is a schematic diagram of the inner cleaner 3A viewed from the thickness direction. The inner cleaner 3A is formed in a generally rectangular parallelepiped shape. The inner cleaner 3A has a longitudinal direction, a lateral direction, and a thickness direction. The inner cleaner 3A is disposed on the inner surface 12a (see FIG. 2) of the inner door 12 so that the thickness direction coincides with the normal direction of the inner surface 12a. Hereinafter, the side of the inner door 12 in the thickness direction will be referred to as the "front side," and the side opposite the inner door 12 in the thickness direction will be referred to as the "rear side."

[0021] Figure 5 is an exploded perspective view of the inner cleaner 3A. The inner cleaner 3A has a cleaning member 4A that contacts the inner surface 12a (see Figure 2) of the inner door 12. The inner cleaner 3A may further have a magnet 5A that generates a magnetic force that maintains the inner cleaner 3A and the opposing member 3B facing each other, and a casing 6A that airtightly houses the magnet 5A. The inner cleaner 3A may further have a support base 81 that supports the magnet 5A and a fastening member 7A that attaches the cleaning member 4A to the casing 6A.

[0022] 6 is a cross-sectional view taken along line VI-VI in FIG. 4. The casing 6A is a box-shaped member having an internal storage space. In this example, the storage space is sealed. The casing 6A is made of, for example, metal. The casing 6A includes an inner case 60 and an outer case 65.

[0023] Each of the inner case 60 and the outer case 65 is shaped like a substantially rectangular parallelepiped box with an opening. Specifically, the inner case 60 has a substantially rectangular bottom plate 61 and four side plates 62 bent from each of the four sides of the bottom plate 61. The outer surface of the bottom plate 61 forms an opposing surface 61a that faces the inner surface 12a of the inner door 12. In this example, the opposing surface 61a is substantially flat. Every two adjacent side plates 62 are connected to each other. In other words, the edges of the four side plates 62 opposite the bottom plate 61 form the opening edge 63 of the inner case 60. The outer surfaces of the four side plates 62 form side surfaces 62a that bend from the opposing surface 61a.

[0024] The outer case 65 has a substantially rectangular bottom plate 66 and four side plates 67 bent from each of the four sides of the bottom plate 66. Any two adjacent side plates 67 are connected to each other. That is, the edges of the four side plates 67 opposite the bottom plate 66 form an opening edge 68 of the outer case 65.

[0025] The planar shape of the bottom plate 61 of the inner case 60 is smaller than that of the bottom plate 66 of the outer case 65. A flange 64 that extends outward from the inner case 60 is connected to an opening edge 63 of the inner case 60.

[0026] The inner case 60 is disposed inside the outer case 65. Specifically, an opening edge 63 of the inner case 60 comes into contact with a bottom plate 66 of the outer case 65. The flange 64 is joined to the bottom plate 66 of the outer case 65 by, for example, bolts or welding. The opening of the inner case 60 is closed by the bottom plate 66 of the outer case 65. This forms a sealed storage space in the casing 6A.

[0027] At this time, at least the bottom plate 61 of the inner case 60 protrudes outward from the opening of the outer case 65. That is, the bottom plate 61 is located outside the outer case 65. Specifically, the width of the side plate 62 of the inner case 60 (i.e., the dimension of the side plate 62 in the direction away from the bottom plate 61) is greater than the width of the side plate 67 of the outer case 65 (i.e., the dimension of the side plate 67 in the direction away from the bottom plate 66).

[0028] The support base 81 is disposed within the storage space of the casing 6A. The support base 81 is connected to the inner surface of the bottom plate 66 of the outer case 65, for example, by bolts. The support base 81 attaches the magnet 5A to the casing 6A so that the magnet 5A is located close to the bottom plate 61 of the inner case 60, i.e., the inner door 12. The support base 81 includes a mounting portion 83 to which the magnet 5A is attached. The mounting portion 83 extends substantially parallel to the bottom plate 66 of the outer case 65. The distance between the magnet 5A and the bottom plate 61 can be adjusted by using various support bases 81 with different thickness dimensions. This allows the attractive force between the inner cleaner 3A and the opposing member 3B to be adjusted. Alternatively, a spacer may be disposed between the mounting portion 83 of the support base 81 and the magnet 5A, and the magnet 5A may be attached to the mounting portion 83 via the spacer. The distance between the magnet 5A and the bottom plate 61 may be adjusted by the spacer.

[0029] The magnet 5A generates a magnetic field to maintain the inner cleaner 3A facing the opposing member 3B. The magnet 5A is disposed within the accommodation space of the casing 6A. It is preferable to use a magnet with excellent heat resistance as the magnet 5A. In this example, the magnet 5A includes a first magnet 51 and a second magnet 52 aligned in the longitudinal direction.

[0030] The first magnet 51 has a substantially rectangular plate shape in a plan view. The first magnet 51 is arranged so that the thickness direction of the first magnet 51 is substantially parallel to the thickness direction of the inner cleaner 3A. The first magnet 51 is magnetized in the thickness direction of the first magnet 51. Two surfaces of the first magnet 51 facing the thickness direction of the first magnet 51 are each magnetic pole surfaces.

[0031] The second magnet 52 has a substantially rectangular plate shape in a plan view. The second magnet 52 is arranged so that the thickness direction of the second magnet 52 is substantially parallel to the thickness direction of the inner cleaner 3A. The second magnet 52 is magnetized in the thickness direction of the second magnet 52. Two surfaces of the second magnet 52 facing the thickness direction of the second magnet 52 are each magnetic pole surfaces.

[0032] The first magnet 51 and the second magnet 52 are each arranged with their magnetic pole faces facing forward, i.e., facing toward the inner door 12. This causes the magnetic flux from the first magnet 51 and the second magnet 52 to extend so as to penetrate the bottom plate 61 of the inner case 60. At this time, the magnetic poles of the magnetic pole faces facing forward are different between the first magnet 51 and the second magnet 52. In this example, the magnetic pole of the magnetic pole face facing forward of the first magnet 51 is a north pole, and the magnetic pole face of the magnetic pole face facing forward of the second magnet 52 is a south pole.

[0033] The first magnet 51 and the second magnet 52 are each attached to the support base 81 by, for example, screws or the like.

[0034] The cleaning member 4A is exposed to the outside of the casing 6A at the front side. The cleaning member 4A of the inner cleaner 3A comes into contact with the inner surface 12a of the inner door 12. The cleaning member 4A of the inner cleaner 3A removes water droplets and the like on the inner surface 12a when the inner cleaner 3A slides on the inner surface 12a.

[0035] The cleaning member 4A is formed in a sheet shape. The cleaning member 4A is disposed on at least the facing surface 61a of the inner case 60. In this example, the cleaning member 4A is disposed across both the facing surface 61a and the side surface 62a of the casing 6A. That is, the cleaning member 4A is disposed so as to cover both the facing surface 61a and the side surface 62a of the casing 6A.

[0036] The cleaning member 4A is preferably made of a water-absorbent, stretchable material to which dirt and other particles easily adhere. In this example, the cleaning member 4A is made of heat-resistant felt. The heat-resistant felt may have a heat resistance of, for example, 400°C or higher, more specifically, a thermal decomposition temperature of 400°C or higher.

[0037] The cleaning member 4A is attached to the casing 6A by fastening members 7A. The fastening members 7A are fastened to the side surface 62a of the inner case 60. That is, the fastening members 7A fix the cleaning member 4A to the side surface 62a of the inner case 60. The fastening members 7A are arranged in the space between the side plate 62 of the inner case 60 and the side plate 67 of the outer case 65. In this example, as shown in FIG. 5, the inner cleaner 3A has four fastening members 7A. One fastening member 7A is arranged at a position corresponding to each of the four side plates 62 of the inner case.

[0038] The structure for attaching the cleaning member 4A to the casing 6A using the fastening member 7A will be described in detail. The fastening member 7A includes a screw 71 and a pressing member 72. The inner case 60 has screw holes 62b into which the screws 71 are fastened. In this example, the inner case 60 has multiple screw holes 62b. More specifically, each screw hole 62b is formed in each of the four side plates 62 of the inner case 60. Specifically, each side plate 62 has two screw holes 62b. The cleaning member 4A has through holes 41 through which the screws 71 are inserted. In this example, the cleaning member 4A has multiple through holes 41. Each through hole 41 is positioned corresponding to a corresponding one of the multiple screw holes 62b. That is, at least one through hole 41 is positioned in each of the cleaning member 4A corresponding to each side plate 62 of the inner case 60. The cleaning member 4A is attached to the casing 6A by fastening the screws 71 through the through holes 41 into the screw holes 62b.

[0039] The pressing members 72 press the cleaning members 4A against the casing 6A. In this example, the pressing members 72 are in the shape of a substantially rectangular plate in a plan view. In this example, the inner cleaner 3A has four pressing members 72. One pressing member 72 is disposed at a position corresponding to each of the four side plates 62 of the inner case 60. In other words, the cleaning members 4A are pressed against the inner case 60 by the pressing members 72.

[0040] As shown in FIG. 6, the pressing member 72 includes a protruding portion 74 that protrudes toward the cleaning member 4A. In this example, the pressing member 72 includes two protruding portions 74 and an intermediate portion 73 disposed between the two protruding portions 74. The intermediate portion 73 extends substantially parallel to the side surface 62a of the inner case 60. The protruding portion 74 is inclined relative to the side surface 62a so that the protruding portion 74 approaches the side surface 62a as it moves away from the intermediate portion 73. More specifically, the pressing member 72 has a substantially rectangular plate shape in plan view as a whole. However, since the pressing member 72 has the protruding portion 74, it is not flat as a whole. The intermediate portion 73 has a through hole 75 through which the screw 71 is inserted. In this example, the intermediate portion 73 has a plurality of through holes 75.

[0041] 7, 8, 9, and 10 are explanatory diagrams illustrating a method for attaching the cleaning member 4A to the casing 6A using the fastening member 7A. FIGS. 7 and 8 are schematic side views of the inner case 60 and the cleaning member 4A viewed from the longitudinal direction. FIGS. 9 and 10 are schematic side views of the inner case 60, the cleaning member 4A, and the pressing member 72 viewed from the longitudinal direction. Specifically, FIG. 7 is a side view of the cleaning member 4A arranged on the outer surface of the inner case 60. FIG. 8 is a side view of the cleaning member 4A in an extended state. FIG. 9 is a side view of the pressing member 72 arranged on the outer surface of the cleaning member 4A. FIG. 10 is a side view of the cleaning member 4A and the pressing member 72 fastened to the inner case 60 with screws.

[0042] First, as shown in FIG. 7 , the cleaning member 4A is placed on the outer surface of the inner case 60. Before the screws 71 are inserted, the through holes 41 are offset from the screw holes 62b. That is, the through holes 41 are offset. Specifically, the through holes 41 are offset forward from the screw holes 62b. That is, the through holes 41 are offset inward in the in-plane direction of the sheet-like cleaning member 4A from the screw holes 62b. Next, as shown in FIG. 8 , the user pulls the cleaning member 4A rearward. The through holes 41 of the cleaning member 4A move rearward, that is, outward in the in-plane direction of the sheet-like cleaning member 4A. As the cleaning member 4A is pulled and stretched, the through holes 41 overlap with the screw holes 62b. This allows the screws 71 fastened to the screw holes 62b to be inserted into the cleaning member 4A. As the cleaning member 4A is pulled and stretched, the cleaning member 4A becomes substantially flat. Thereafter, as shown in Fig. 9, the pressing member 72 is placed on the outer surface of the cleaning member 4A. At this time, when viewed from the longitudinal direction, the position of the through hole 75 of the pressing member 72 is approximately aligned with the positions of the screw hole 62b and the through hole 41 of the cleaning member 4A. As shown in Fig. 10, the user inserts the screw 71 through the through hole 75 of the pressing member 72 and the through hole 41 of the cleaning member 4A and screws the screw 71 into the screw hole 62b. At this time, the protrusion 74 of the pressing member 72 is pushed into the cleaning member 4A. As a result, the cleaning member 4A is firmly attached to the casing 6A in a pulled state.

[0043] FIG. 11 is a cross-sectional view of the opposing member 3B. The basic configuration of the opposing member 3B is the same as that of the inner cleaner 3A. That is, similar to the inner cleaner 3A shown in FIG. 5, the opposing member 3B has a casing 6B including an inner case 60 and an outer case 65, a magnet 5B supported by a support base 81 disposed within the inner case 60, and a cleaning member 4B fastened to the outer surface of the inner case 60 by a fastening member 7B. However, when the inner cleaner 3A and the opposing member 3B are disposed opposite each other across the inner door 12, the magnetic poles of the opposing magnets 5A and 5B are different. Note that the other configurations are the same as those of the inner cleaner 3A, and therefore detailed description thereof will be omitted.

[0044] Specifically, the opposing member 3B is disposed on the outer surface 12b so that its thickness direction coincides with the normal direction of the outer surface 12b of the inner door 12. The cleaning member 4B of the opposing member 3B is in contact with the outer surface 12b of the inner door 12. The cleaning member 4B of the opposing member 3B removes water droplets and the like on the outer surface 12b when the opposing member 3B slides over the outer surface 12b.

[0045] The magnet 5B generates a magnetic field to maintain the inner cleaner 3A facing the opposing member 3B. The magnet 5B is disposed within the storage space of the casing 6B. It is preferable to use a magnet with excellent heat resistance for the magnet 5B. In this example, the magnet 5B includes a first magnet 51 and a second magnet 52 aligned in the longitudinal direction. As shown in FIG. 2 , when the inner cleaner 3A and the opposing member 3B are disposed facing each other across the inner door 12, the first magnet 51 of the opposing member 3B faces the second magnet 52 of the inner cleaner 3A, and the second magnet 52 of the opposing member 3B faces the first magnet 51 of the inner cleaner 3A. The configuration of the first magnet 51 of the opposing member 3B is the same as the configuration of the first magnet 51 of the inner cleaner 3A, and the configuration of the second magnet 52 of the opposing member 3B is the same as the configuration of the second magnet 52 of the inner cleaner 3A. Therefore, detailed description of the first magnet 51 and the second magnet 52 of the opposing member 3B will be omitted.

[0046] With this configuration of the magnet 5B, when the opposing member 3B is placed opposite the inner cleaner 3A via the inner door 12, the north pole of the first magnet 51 of the inner cleaner 3A faces the south pole of the second magnet 52 of the opposing member 3B, and the south pole of the second magnet 52 of the inner cleaner 3A faces the north pole of the first magnet 51 of the opposing member 3B. As a result, the magnet 5A of the inner cleaner 3A and the magnet 5B of the opposing member 3B attract each other, and the state in which the inner cleaner 3A and the opposing member 3B face each other is maintained by magnetic force.

[0047] Next, a method of using the cleaner 2 will be described with reference to FIG. 2. First, before a test, a user places the inner cleaner 3A on the inner surface 12a of the inner door 12 with both the inner door 12 and the outer door 13 (see FIG. 1) open. At this time, the cleaning member 4A of the inner cleaner 3A is brought into contact with the inner surface 12a of the inner door 12. Next, the opposing member 3B is placed on the outer surface 12b of the inner door 12 so as to face the inner cleaner 3A across the inner door 12. At this time, the first magnet 51 of the inner cleaner 3A and the second magnet 52 of the opposing member 3B face each other across the inner door 12, and the second magnet 52 of the inner cleaner 3A and the first magnet 51 of the opposing member 3B face each other across the inner door 12. Furthermore, the cleaning member 4A of the opposing member 3B is brought into contact with the outer surface 12b of the inner door 12. The inner cleaner 3A and the opposing member 3B are attracted to each other by magnetic force, maintaining the inner cleaner 3A and the opposing member 3B facing each other. If water droplets or the like adhere to the inner door 12 during testing, the user opens the outer door 13, grasps the outer case 65 of the opposing member 3B, and slides the opposing member 3B along the outer surface 12b of the inner door 12. Following the sliding of the opposing member 3B, the inner cleaner 3A also slides along the inner surface 12a of the inner door 12. This allows the water droplets or the like adhering to the inner surface 12a and outer surface 12b of the inner door 12 to be removed.

[0048] In this cleaner 2, the inner cleaner 3A is maintained facing the opposing member 3B by magnetic force, and the inner cleaner 3A slides on the inner surface 12a of the inner door 12 as the opposing member 3B slides on the outer surface 12b of the inner door 12. This allows the inner cleaner 3A to be freely moved to a desired position on the inner door 12 to remove water droplets and other debris adhering to the inner surface 12a of the inner door 12. As a result, the cleaning range can be flexibly changed and expanded compared to a configuration that removes water droplets and other debris using a wiper attached to the inner door 12. In addition, because the inner cleaner 3A can be slid using the opposing member 3B located on the outside of the inner door 12, water droplets and other debris adhering to the inner surface 12a of the inner door 12 can be removed without opening the inner door 12. This allows the internal environment of the environment creating device 100 to be maintained during testing. In this example, the opposing member 3B also includes a cleaning member 4B, so that the outer surface 12b of the inner door 12 as well as the inner surface 12a can be cleaned simultaneously.

[0049] In this example, magnet 5A is housed airtight in casing 6A. This makes it possible to prevent moisture from entering casing 6A even if the surroundings of casing 6A are exposed to a high-humidity environment, for example. As a result, deterioration of magnet 5A due to moisture can be prevented. Similarly, magnet 5B is housed airtight in casing 6B. This makes it possible to prevent moisture from entering casing 6B even if the surroundings of casing 6B are exposed to a high-humidity environment, for example. As a result, deterioration of magnet 5B due to moisture can be prevented.

[0050] In this example, both the inner cleaner 3A and the opposing member 3B have magnets, and the inner cleaner 3A and the opposing member 3B are attracted to each other by magnetic force. Therefore, the attractive force between the inner cleaner 3A and the opposing member 3B can be made larger than in a case where, for example, only one of the inner cleaner 3A and the opposing member 3B has a magnet and the other of the inner cleaner 3A and the opposing member 3B has only a metal member that is attracted to the magnet. As a result, even if, for example, the inner door 12 is thick, the inner cleaner 3A and the opposing member 3B can be maintained facing each other via the inner door 12.

[0051] If the magnets 5A and 5B were each a single magnet and the inner cleaner 3A and the opposing member 3B were attracted to each other at one location within the surface of the inner door 12, there is a risk that the inner cleaner 3A and the opposing member 3B would rotate within the surface of the inner door 12. However, in this embodiment, the magnets 5A and 5B each include a first magnet 51 and a second magnet 52, and the first magnet 51 of the inner cleaner 3A is attracted to the second magnet 52 of the opposing member 3B, and the second magnet 52 of the inner cleaner 3A is attracted to the first magnet 51 of the opposing member 3B. In other words, in this embodiment, the inner cleaner 3A and the opposing member 3B are attracted to each other at two locations within the surface of the inner door 12. This prevents the inner cleaner 3A and the opposing member 3B from rotating within the surface of the inner door 12.

[0052] If the cleaning member 4A were chemically attached to the casing 6A using an adhesive or the like, there is a risk that the cleaning member 4A would peel off from the casing 6A if the inner cleaner 3A were exposed to a harsh environment. However, in this embodiment, the cleaning member 4A in the inner cleaner 3A is attached to the casing 6A using fastening members 7A. That is, the cleaning member 4A is physically attached to the casing 6A. This prevents the cleaning member 4A from peeling off from the casing 6A, even if the inner cleaner 3A is exposed to a harsh environment, such as high temperature and humidity. Particularly in this embodiment, the pressing member 72 includes a protrusion 74. The protrusion 74 sinks into the cleaning member 4A when the pressing member 72 is pressed against the cleaning member 4A. This improves the attachment strength of the cleaning member 4A to the casing 6A.

[0053] The cleaning member 4A is attached to the casing 6A in an extended state. This improves the flatness of the cleaning member 4A, making it easier for the inner cleaner 3A to slide on the inner surface 12a of the inner door 12. Similarly, it makes it easier for the opposing member 3B to slide on the outer surface 12b of the inner door 12.

[0054] The fastening member 7A of the inner cleaner 3A is fastened to a side surface 62a of the inner case 60. The side surface 62a is bent toward an opposing surface 61a that faces the inner surface 12a of the inner door 12. This prevents the fastening member 7A from interfering with the inner door 12 when the inner cleaner 3A slides on the inner surface 12a of the inner door 12.

[0055] Similarly, the fastening member 7B of the opposing member 3B is fastened to a side surface 62a of the inner case 60. The side surface 62a is bent toward an opposing surface 61a that faces the outer surface 12b of the inner door 12. Therefore, when the opposing member 3B slides on the outer surface 12b of the inner door 12, interference between the fastening member 7B and the inner door 12 can be suppressed.

[0056] In this example, the cleaning members 4A and 4B are made of heat-resistant felt, so that even if the inner cleaner 3A and the opposing member 3B are exposed to a high-temperature environment, the cleaning members 4A and 4B can be prevented from deteriorating.

[0057] The fastening member 7B is disposed in the space between the side plate 62 of the inner case 60 and the side plate 67 of the outer case 65. This allows the user to grip the outer case 65 of the opposing member 3B and slide the opposing member 3B without touching the fastening member 7B. As a result, loosening of the fastening member 7B due to the user's hand touching the fastening member 7B can be prevented.

[0058] Next, an environment forming device 200 according to a first modified example will be described. Fig. 12 is a perspective view of the environment forming device 200 according to the first modified example. The environment forming device 200 differs from the environment forming device 100 in that it has a storage pocket 15. The following description will focus on the parts of the configuration of the environment forming device 200 that differ from the environment forming device 100.

[0059] The environment creating device 200 further includes a storage pocket 15 attached to the inner surface 12a of the inner door 12. The storage pocket 15 stores the inner cleaner 3A, which slides on the inner surface 12a of the inner door 12 in conjunction with the opposing member 3B, in a removable manner.

[0060] 13 is a cross-sectional view of the inner door 12 and the storage pocket 15, illustrating how to use the storage pocket 15. The storage pocket 15 has an internal storage space and opens upward. This opening serves as an entrance and exit for the inner cleaner 3A. The storage pocket 15 is made of, for example, metal.

[0061] Specifically, the storage pocket 15 includes a side plate 16 extending in the vertical direction and a bottom plate 17 connected to the lower end of the side plate 16. Specifically, the side plate 16 includes a first side plate 16a (see FIG. 12), a second side plate 16b (see FIG. 12), and a third side plate 16c. The first side plate 16a is attached to the inner surface 12a of the inner door 12 and is disposed so as to be approximately perpendicular to the inner surface 12a of the inner door 12. The second side plate 16b is attached to the inner surface 12a of the inner door 12 and is disposed so as to be approximately perpendicular to the inner surface 12a of the inner door 12 and face the first side plate 16a. The third side plate 16c connects the end of the first side plate 16a opposite the inner door 12 to the end of the second side plate 16b opposite the inner door 12. The third side plate 16c is disposed so as to be approximately parallel to the inner surface 12a of the inner door 12. The distance between the inner surface 12a of the inner door 12 and the third side plate 16c is slightly larger than the size in the thickness direction of the inner cleaner 3A. The bottom plate 17 is attached to the inner surface 12a of the inner door 12, and three end faces of the bottom plate 17 are connected to the lower ends of the first side plate 16a, the second side plate 16b, and the third side plate 16c, respectively.

[0062] In this example, the width W of the storage pocket 15 in the direction perpendicular to the inner surface 12a of the inner door 12 decreases downward at the bottom of the storage pocket 15. Specifically, the bottom plate 17 is inclined with respect to the inner surface 12a of the inner door 12 so as to approach the inner door 12 downward.

[0063] During testing, for example, when a user leaves the inner cleaner 3A inside the environment creating device 200 without using it, the user slides the inner cleaner 3A and the opposing member 3B in the in-plane direction of the inner door 12 to accommodate the inner cleaner 3A in the storage pocket 15. Then, the user pulls the opposing member 3B away from the inner door 12. This releases the opposing state between the inner cleaner 3A and the opposing member 3B. The inner cleaner 3A then remains accommodated in the storage pocket 15. At this time, the storage pocket 15 maintains the inner cleaner 3A, which has been released from the opposing state with the cleaning member 4A facing the inner surface 12a of the inner door 12. In this example, the cleaning member 4A is held in contact with the inner surface 12a of the inner door 12. When the user uses the inner cleaner 3A, the user places the opposing member 3B on the inner door 12 so that it faces the inner cleaner 3A. As a result, the inner cleaner 3A is attracted to the opposing member 3B by the magnetic force, and the inner cleaner 3A and the opposing member 3B are brought into an opposing state.

[0064] For example, during a high-temperature test, if the facing member 3B is left facing the inner cleaner 3A for a long period of time, the temperature of the facing member 3B may increase, reducing the ease of handling of the cleaner 2. In the environment creating device 200 described above, for example, when the inner cleaner 3A and the facing member 3B are not in use, the inner cleaner 3A can be stored in the storage pocket 15 and the facing member 3B can be separated from the inner door 12. This allows the facing member 3B to be stored outside the environment creating device 200. As a result, the temperature rise of the facing member 3B can be suppressed and the ease of handling of the cleaner 2 can be improved. Furthermore, in this example, the width W of the lower portion of the storage pocket 15 in a direction perpendicular to the inner surface 12a of the inner door 12 decreases downward. This allows the cleaning member 4A of the inner cleaner 3A to be compressed in a direction perpendicular to the inner surface 12a of the inner door 12 when the inner cleaner 3A is stored in the storage pocket 15. As a result, moisture and the like absorbed by the cleaning member 4A can be removed. Furthermore, in this example, the distance between the inner surface 12a of the inner door 12 and the third side panel 16c is slightly larger than the size of the inner cleaner 3A in the thickness direction. This allows the inner cleaner 3A to be smoothly stored in the storage pocket 15. In addition, the inner cleaner 3A, which has been released from the state of facing the opposing member 3B, can be effectively held in a state where the cleaning member 4A faces the inner surface 12a of the inner door 12.

[0065] Next, an inner cleaner 303A according to a second modified example will be described. Fig. 14 is a cross-sectional view of the inner cleaner 303A according to the second modified example. The inner cleaner 303A differs from the inner cleaner 3A in that it has a metal member 91 that attracts a magnet and a spacer 92. The following description will focus on the parts of the configuration of the inner cleaner 303A that differ from the inner cleaner 3A.

[0066] The inner cleaner 303A has a metal member 91 instead of the magnet 5A. The metal member 91 is made of a metal material that attracts magnets. More specifically, the metal member 91 is made of a ferromagnetic material. The metal member 91 is made of stainless steel, for example. When the inner cleaner 303A and the opposing member 3B face each other with the inner door 12 between them, the metal member 91 attracts the magnet 5B of the opposing member 3B. This allows the inner cleaner 303A and the opposing member 3B to maintain their opposing state by magnetic force.

[0067] The spacer 92 adjusts the distance between the metal member 91 and the magnet 5B of the opposing member 3B when the inner cleaner 303A and the opposing member 3B face each other via the inner door 12. That is, the spacer 92 adjusts the attractive force between the metal member 91 and the magnet 5B of the opposing member 3B. The spacer 92 is plate-shaped and extends substantially parallel to the bottom plate 66 of the outer case 65. The spacer 92 is attached to the mounting portion 83 of the support base 81 by, for example, screws. In this example, the inner cleaner 303A has multiple spacers 92, specifically, two spacers 92. The multiple spacers 92 are stacked in the thickness direction. The distance between the magnet 5B of the opposing member 3B and the metal member 91 can be changed by changing the number of the multiple spacers 92 or the thickness of each spacer 92. The aforementioned metal member 91 is attached to the frontmost spacer 92 of the multiple spacers 92 by, for example, screws.

[0068] For example, in an environment creating device that creates high-pressure and low-pressure internal environments, the storage space of the casing 6A may not be sealed to prevent a pressure difference between the inside and outside of the casing 6A. In the inner cleaner 303A described above, instead of a magnet, a metal member 91 that is attracted to the magnet is disposed inside the casing 6A. This reduces adverse effects such as deterioration of the magnet when moisture or the like enters the storage space, which can occur as a result of not sealing the storage space of the casing 6A. The inner cleaner 303A also includes a spacer 92. This allows for easy adjustment of the attractive force between the magnet 5B of the opposing member 3B and the metal member 91.

[0069] Other Embodiments As described above, the above embodiment has been described as an example of the technology disclosed in this application. However, the technology of the present disclosure is not limited to this and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made as appropriate. Furthermore, the components described in the above embodiment can be combined to create new embodiments. Furthermore, the components described in the accompanying drawings and detailed description may include not only components essential for solving the problem, but also components that are not essential for solving the problem in order to exemplify the technology. Therefore, the fact that these non-essential components are described in the accompanying drawings or detailed description should not be interpreted as immediately determining that these non-essential components are essential.

[0070] The environment forming device is not limited to a thermo-hygrostat. For example, the environment forming device may be a device capable of forming high-pressure and low-pressure environments inside. The environment forming device 100 may not have the inner door 12. In this case, the outer door 13 may have an observation window as a light-transmitting member, and the cleaner 2 may be disposed in the observation window. The light-transmitting member is not limited to the inner door. The light-transmitting member may be made of a material other than glass. For example, the light-transmitting member may be made of a light-transmitting resin.

[0071] The type, number, arrangement, shape, etc. of the magnets are not limited. For example, each of the inner cleaner 3A and the opposing member 3B may have one magnet, or three or more magnets. When each of the inner cleaner 3A and the opposing member 3B has one magnet, the direction of the magnetic flux lines formed by the magnet of the inner cleaner 3A may be opposite to the direction of the magnetic flux lines formed by the magnet of the opposing member 3B so that the inner cleaner 3A and the opposing member 3B attract each other via the inner door 12.

[0072] The cleaning members 4A and 4B are not limited to heat-resistant felt. For example, the cleaning members 4A and 4B may be made of a packing material, hard plastic, or the like. When the cleaning members 4A and 4B are made of a packing material, water droplets can be removed efficiently. When the cleaning members 4A and 4B are made of hard plastic, frost can be removed efficiently.

[0073] The shapes, arrangements, etc. of the cleaning members 4A and 4B are not limited. For example, the cleaning member 4A may be arranged only on the opposing surface 61a of the inner case 60. In this case, the cleaning member 4A may be attached to the opposing surface 61a with screws 71 without using the pressing member 72. The same applies to the cleaning member 4B.

[0074] The cleaning member 4A may be attached to the casing 6A in an unstretched state. The cleaning member 4A does not have to be attached to the casing 6A by the fastening member 7A. For example, the cleaning member 4A may be attached to the casing 6A by adhesive. The same applies to the cleaning member 4B.

[0075] The inner cleaner 3A has a magnet 5A, and the opposing member 3B may have a metal member that attracts the magnet 5A of the inner cleaner 3A instead of the magnet 5B.

[0076] The casing 6A does not have to accommodate the magnet 5A in an airtight manner, and the casing 6B does not have to accommodate the magnet 5B in an airtight manner.

[0077] The fastening member 7A is not limited to the configuration shown in Fig. 5. For example, the fastening member 7A does not have to include the pressing member 72. The number, shape, etc. of the pressing member 72 are also not limited. For example, the protruding portion 74 of the pressing member 72 may be a projection that protrudes from the middle portion 73 of the pressing member 72 toward the side surface 62a of the inner case 60. The same applies to the fastening member 7B.

[0078] [Aspect] The above embodiments are specific examples of the following aspects.

[0079] (Mode 1) The cleaner 2 is a cleaner 2 for an environment-forming device having a light-transmitting member (inner door 12) arranged in a housing 1, and has a cleaning member 4A that contacts the inner surface 12a of the light-transmitting member (inner door 12), and is equipped with an inner cleaner 3A, 303A that is arranged on the inner surface 12a of the light-transmitting member (inner door 12), and an opposing member 3B that is arranged on the outer surface 12b of the light-transmitting member (inner door 12) and faces the inner cleaner 3A, 303A across the light-transmitting member (inner door 12), and the inner cleaner 3A, 303A is maintained in an opposing state to the opposing member 3B by magnetic force, and slides on the inner surface 12a of the light-transmitting member (inner door 12) in accordance with the sliding of the opposing member 3B on the outer surface 12b of the light-transmitting member (inner door 12).

[0080] According to this configuration, the inner cleaners 3A, 303A can be freely moved to a desired position on the inner door 12 to remove water droplets and the like adhering to the inner surface 12a of the inner door 12. As a result, the cleaning range can be expanded more flexibly than when removing water droplets and the like using a wiper attached to the inner door 12, for example.

[0081] (Aspect 2) In the cleaner 2 according to aspect 1, at least one of the inner cleaner 3A, 303A and the opposing member 3B has a magnet 5A that generates the magnetic force and a casing 6A that accommodates the magnet 5A in an airtight manner.

[0082] With this configuration, even if the surroundings of the casing 6A are exposed to a high humidity environment, for example, it is possible to prevent moisture from entering the inside of the casing 6A, and as a result, it is possible to prevent the magnet 5A from being deteriorated by moisture.

[0083] (Aspect 3) In the cleaner 2 described in aspect 1 or aspect 2, the inner cleaner 3A, 303A has a casing 6A, and the casing 6A includes an opposing surface 61a that faces the inner surface 12a of the translucent member (inner door 12), and the cleaning member 4A is sheet-shaped and is arranged at least on the opposing surface 61a of the casing 6A and attached to the casing 6A by a fastening member 7A.

[0084] If the cleaning members 4A were chemically attached to the casing 6A with an adhesive, there is a risk that the cleaning members 4A would peel off from the casing 6A if the inner cleaner 3A, 303A were exposed to a harsh environment. According to the above configuration, in the inner cleaner 3A, 303A, the cleaning members 4A are attached to the casing 6A with the fastening members 7A. That is, the cleaning members 4A are physically attached to the casing 6A. This makes it possible to prevent the cleaning members 4A from peeling off from the casing 6A, for example, even if the inner cleaner 3A, 303A is exposed to a harsh environment such as high temperature and high humidity.

[0085] (Embodiment 4) In the cleaner 2 described in any one of embodiments 1 to 3, the fastening member 7A includes a pressing member 72 that presses the cleaning member 4A against the casing 6A, and the pressing member 72 includes a protrusion 74 that protrudes toward the cleaning member 4A.

[0086] According to this configuration, when the cleaning member 4A is pressed against the casing 6A, the protrusion 74 can be caused to sink into the cleaning member 4A, thereby improving the attachment strength of the cleaning member 4A to the casing 6A.

[0087] (Mode 5) In the cleaner 2 described in any one of modes 1 to 4, the fastening member 7A includes a screw 71, the cleaning member 4A has a through hole 41 through which the screw 71 is inserted, the casing 6A has a screw hole 62b through which the screw 71 is fastened, the through hole 41 is positioned offset with respect to the screw hole 62b before the screw 71 is inserted, and when the cleaning member 4A is pulled and stretched, it overlaps with the screw hole 62b, and the screw 71 fastened to the screw hole 62b can be inserted.

[0088] With this configuration, the cleaning member 4A can be attached to the casing 6A in an extended state, which improves the flatness of the cleaning member 4A and makes it easier for the inner cleaner 3A to slide on the inner surface 12a of the inner door 12.

[0089] (Mode 6) In the cleaner 2 described in any one of modes 1 to 5, the casing 6A further includes a side surface 62a that bends from the opposing surface 61a, the cleaning member 4A is arranged across both the opposing surface 61a and the side surface 62a, and the fastening member 7A is fastened to the side surface 62a.

[0090] According to this configuration, when the inner cleaner 3A slides on the inner surface 12a of the inner door 12, the fastening member 7A can be prevented from interfering with the inner door 12.

[0091] (Seventh Aspect) The environment forming device 100, 200 includes a housing 1, a light-transmitting member (inner door 12) disposed in the housing 1, and the cleaner 2 according to any one of the first to sixth aspects.

[0092] According to this configuration, the cleaning range can be expanded compared to removing water droplets and the like using a wiper attached to the inner door 12, for example.

[0093] (Embodiment 8) The environment forming device 200 described in embodiment 7 further includes a storage pocket 15 that is attached to the inner surface 12a of the translucent member (inner door 12) and into which the inner cleaner 3A, 303A, which slides on the inner surface 12a of the translucent member (inner door 12) in conjunction with the opposing member 3B, can freely move in and out, and the storage pocket 15 holds the inner cleaner 3A, 303A, which has been released from its state of opposing the opposing member 3B, in a state in which the cleaning member 4A faces the inner surface 12a of the translucent member (inner door 12).

[0094] For example, during a high-temperature test, if the facing member 3B is left facing the inner cleaner 3A, 303A for a long period of time, the temperature of the facing member 3B may rise, which may reduce the ease of handling of the cleaner 2. With this configuration, for example, when the inner cleaner 3A, 303A and the facing member 3B are not in use, the inner cleaner 3A, 303A can be stored in the storage pocket 15, and the facing member 3B can be separated from the inner door 12 and stored outside the environment creating device 200. This makes it possible to suppress a rise in the temperature of the facing member 3B and improve the ease of handling of the cleaner 2. [Explanation of symbols]
