[0008] Technical problem to be solved by the invention

[0009] The test chamber (article storage room) of an environmental testing device is generally composed of a main body surrounded by a thermally insulating wall and a door. However, the boundary between the main body and the door tends to have poorer thermal insulation performance than other areas due to its structure.

[0010] Therefore, condensation may sometimes form on a portion of the main body near the door. For example, when the test chamber is maintained at a high temperature and high humidity, the temperature and humidity inside the main body are higher than those outside. Furthermore, because the interface between the main body and the door is poorly insulated, the temperature of the main body inner wall near the interface is lower than that of other areas due to the influence of the outside air temperature. The air at the interface is cooled by the main body inner wall near the interface. Consequently, condensation forms on the main body inner wall near the interface between the main body and the door.

[0011] Therefore, when the user opens the door, water droplets may fall from the ceiling of the test room, hitting the user or landing in front of the user's eyes, causing discomfort. In addition, the falling water droplets may splash onto objects such as the test object.

[0012] The present invention solves the above-mentioned technical problems of the prior art and provides an environment forming device capable of suppressing water droplets from falling when a door is opened.

[0013] Means for solving technical problems

[0014] An embodiment for solving the above-mentioned technical problem has an item placement room for placing items, and the item placement room is part or all of an area surrounded by a main body and a door. The environment forming device is capable of adjusting the item placement room to a specified environment, and is characterized in that it has a scraping component and a dew-collecting component installed on the door, and the scraping component is configured to contact the ceiling of the main body and / or water attached to the ceiling.

[0015] The environment forming device of this embodiment includes an article placement room for placing articles, and can adjust the article placement room to a predetermined environment.

[0016] The article storage room is a part or the whole of an area surrounded by a main body and a door, and the interior can be opened by opening the door.

[0017] The environment forming device of this mode is provided with a scraping member and a dew collecting member on the door, and the scraping member is arranged in a manner so as to hit the ceiling of the main body or water attached to the ceiling.

[0018] Therefore, when opening the door, scrape out component and move together with the door, scrape out component and wipe the ceiling or the water that is attached to the ceiling. As a result, the water drop that is attached to the ceiling is wiped out by scraping out component and enters the dew receiving component.

[0019] In the above manner, the door is preferably a swing door.

[0020] Here, a swing door is a door structure that swings. For example, a swing door is a door structure in which one end is attached to the main body side by a hinge or the like, and the other end moves toward or away from the main body.

[0021] In each of the above aspects, the exposure member preferably has a length extending across substantially the entire width of the article storage chamber.

[0022] According to this aspect, water droplets adhering to the entire width of the ceiling can be received.

[0023] In each of the above-mentioned methods, preferably, there is a groove formed by the exposure component and the door or a groove formed by the exposure component, and the door has an edge on the installation side of the main body and an edge on the free end side, and the bottom of the groove is inclined downward from the free end side toward the installation side.

[0024] According to this aspect, the collected water droplets (water) can be collected and drained to the door installation side.

[0025] The door mounting side moves less when the door is opened or closed, so the user is less likely to notice it. In other words, the door mounting side is inconspicuous. This environmental shaping device can discharge condensation water unobtrusively.

[0026] Effects of the Invention

[0027] The environment forming device of the present invention can prevent water droplets from falling when the door is opened. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Hereinafter, the environment forming device 1 according to the embodiment of the present invention will be described. Specifically, the environment forming device 1 according to the present embodiment is an environmental testing device.

[0036] like Figure 1 、 Figure 2 、 Figure 3 As shown, the environment-forming device 1 of this embodiment includes a main body 3 formed by a heat-insulating wall 2. The main body 3 includes a ceiling wall 5, a bottom wall 6, an inner wall 7, a left side wall 8, and a right side wall 10, and is open on the front side. The main body 3 is a frame having an opening 11 on the front side.

[0037] A door 15 is provided to cover the opening 11 of the main body 3. The door 15 also has heat insulating properties.

[0038] Door 15 is a quadrilateral swing door, such as Figure 1 As shown, one side is supported by the main body 3 via a hinge 16. The hinge 16 side of the door 15 is a mounting side 17, and the other side is a free end side 18. The mounting side 17 side of the door 15 is fixed to the main body 3 via the hinge 16, and the free end side 18 side swings widely.

[0039] In this embodiment, the main body 3 and the door 15 form a heat insulation tank. Figure 2 As shown, a partition wall 20 is provided, which insulates the interior of the tank from the article storage chamber 22 and the air conditioning unit 25. It should be noted that the environment creation device 1 of this embodiment is used as an environmental testing device, and the article storage chamber 22 is used as a test chamber. Test objects (articles) are placed in the article storage chamber 22.

[0040] like Figure 1 、 Figure 3 As shown, a drainage hole 40 is provided on the bottom wall 6 of the article arrangement chamber 22 and near the installation side 17 of the door 15 .

[0041] In this embodiment, a portion of the area surrounded by the main body 3 and the door 15 is an article placement chamber 22 for placing articles. More specifically, the space between the door 15 and the partition wall 20 in the heat-insulating tank is the article placement chamber 22.

[0042] The present invention is not limited to this structure, and the entire area surrounded by the main body 3 and the door 15 may be the article storage room without the partition wall 20. In this case, temperature-controlled air is supplied to the article storage room from other air conditioning equipment.

[0043] The partition wall 20 has openings at its upper and lower ends. The upper opening functions as an air outlet 26 , and the lower opening functions as an air inlet 23 .

[0044] The article storage chamber 22 and the air conditioning unit 25 are connected at two locations: an air blowing portion 26 and an air introducing portion 23 .

[0045] The air conditioning section 25 is an air conditioning ventilation path that is annularly connected to the article storage chamber 22 and contains an air conditioner (environmental adjustment device) 27 and a blower 30. The air conditioner 27 is composed of a humidifier (humidifying heater) 31, a cooling device 32, and a heating device 33.

[0046] When the blower 30 is activated, air in the storage compartment 22 is introduced into the air conditioning unit 25 through the air intake 23. The air conditioning unit 25 then enters a ventilation state, where the air contacts the air conditioner 27 for heat exchange and humidity adjustment. The adjusted air is then blown out of the air outlet 26 into the storage compartment 22.

[0047] Furthermore, a temperature sensor 37 and a humidity sensor 38 are provided near the air blowing portion 26 .

[0048] The signals of the temperature sensor 37 and the humidity sensor 38 are input to a control device (not shown). Then, the control device compares the detection values ​​of the temperature sensor 37 and the humidity sensor 38 with the set values.

[0049] When the environment forming device 1 is used, the blower 30 is driven to ventilate the air conditioning unit 25 , and the air conditioning unit 27 is controlled so that the detection values ​​of the temperature sensor 37 and the humidity sensor 38 approach the set environmental temperature and humidity.

[0050] Specifically, by operating the blower 30, air in the article storage room 22 is introduced from the air intake section 23 into the air conditioning section 25, passes through the air conditioning equipment 27 in the air conditioning section 25, and is adjusted in temperature and humidity. The air with adjusted temperature and humidity then returns to the article storage room 22 from the air outlet section 26, creating an environment within the article storage room 22 with the desired temperature and humidity.

[0051] Next, a characteristic configuration of the environment forming device 1 according to this embodiment will be described.

[0052] The environment forming device 1 of the present embodiment is provided with a water guide member 50 on the inner surface side of the door 15 .

[0053] like Figure 4 As shown, the water guide member 50 is composed of a dew receiving member 51 and a scraping member 52 .

[0054] like Figure 5 As shown, the dew collecting component 51 receives and collects condensation falling from the ceiling, and is a component that constitutes a groove 70 for allowing water to flow in the width direction of the door 15. It has a longitudinal wall 53 that is a vertical wall based on the installation posture, a bottom wall 55 that is continuous with the longitudinal wall 53 and is a horizontal wall, and an installation wall 56 that is continuous with the bottom wall 55 and is a vertical wall.

[0055] like Figure 4 As shown in (a), a blocking wall 57 is provided at one end of the longitudinal direction of the exposure member 51. Figure 4 As shown in (b), the other end of the exposure member 51 in the longitudinal direction is an open portion 61.

[0056] The total length L of the exposure member 51 is slightly shorter than the width WA of the opening 11 of the main body 3 (see Figure 1 That is, the dew-receiving member 51 has a length that spans substantially the entire width of the article storage chamber 22. The total length L of the dew-receiving member 51 is preferably at least 80% of the width WA of the opening 11 of the main body 3 (which is the same as the width of the article storage chamber 22), and more preferably at least 90%.

[0057] The scraping member 52 is a strip-shaped member. The total length of the scraping member 52 is substantially equal to the total length of the dew-receiving member 51. The upper end of the scraping member 52 is provided so as to protrude upward from the upper end of the dew-receiving member 51.

[0058] Although the material of the scraping member 52 is not limited, it is preferably a soft material that does not absorb water. The scraping member 52 of this embodiment is made of rubber.

[0059] like Figure 4 As shown in FIG. 5A , the scraper 52 is fixed to the vertical wall 53 of the dew-receiving member 51. The scraper 52 is attached to the vertical wall 53 along the length of the dew-receiving member 51. A portion of the scraper 52 protrudes upward from the vertical wall 53 of the dew-receiving member 51. The length of the portion of the scraper 52 protruding upward from the dew-receiving member 51 is greater than the distance between the upper end of the dew-receiving member 51 and the ceiling wall 5.

[0060] like Figure 1 、 Figure 2 As shown, the water guide member 50 is attached to the inner wall 60 of the door 15. The water guide member 50 is attached to the inner wall 60 of the door 15 so that the upper end of the dew receiving member 51 is located slightly lower than the ceiling wall 5 of the main body 3. Furthermore, the water guide member 50 is attached to the inner wall 60 of the door 15 so that the upper end of the portion of the scraper member 52 that protrudes upward from the dew receiving member 51 is in contact with the ceiling wall 5 of the main body 3.

[0061] The attachment position of the water guide member 50 in the width direction of the door 15 is a position where the water guide member 50 enters the opening 11 of the main body 3 when the door 15 is closed.

[0062] Therefore, when the door 15 is closed, the water guide member 50 enters the main body 3 , and the groove 70 formed by the dew receiving member 51 and the inner wall 60 of the door 15 is located below the ceiling wall 5 of the main body 3 and near the opening 11 .

[0063] The water guide member 50 is attached in a posture slightly inclined downward from the free end side 18 side toward the attachment side 17 side.

[0064] When the water guide member 50 is mounted on the inner wall 60 of the door 15, Figure 5 As shown, a groove 70 covered on three sides is formed by the inner wall 60 of the door 15 , the bottom wall 55 of the water guide member 50 , and the vertical wall 53 .

[0065] Specifically, the mounting wall 56 of the water guide member 50 is fixed to the inner wall 60 of the door 15 by screws (not shown). Because a bottom wall 55 is located between the vertical wall 53 and the mounting wall 56 and is perpendicular to the vertical wall 53 and the mounting wall 56, the vertical wall 53 is in a parallel position facing the inner wall 60 of the door 15 with the bottom wall 55 interposed therebetween.

[0066] The bottom wall 55 of the dew contact member 51 functions as a bottom wall of the groove 70 .

[0067] The groove 70 extends in the width direction of the inner wall 60 of the door 15. The upper surface of the groove 70 is open.

[0068] As described above, the water guide member 50 is installed with a slight downward inclination from the free end side 18 toward the mounting side 17. Consequently, the groove 70 is tilted slightly downward from the free end side 18 toward the mounting side 17. In other words, the bottom wall 55 of the groove 70 is tilted slightly downward from the free end side 18 toward the mounting side 17. Consequently, the dew-receiving member 51 has a slope that allows water to flow from the free end side of the door 15 toward the mounting side.

[0069] The groove 70 extends in the width direction of the ceiling wall 5 of the main body portion 3 , and an open surface of the groove 70 faces the ceiling wall 5 .

[0070] The scraping member 52 is in a bent state or a compressed state, and the upper end side of the scraping member 52 is in contact with the ceiling wall 5 .

[0071] In order to carry out the environmental test in this state, the interior of the article arrangement room 22 is adjusted to a high-temperature and high-humidity environment.

[0072] As described above, since the boundary between the main body 3 and the door 15 has poor thermal insulation, the temperature of the inner wall of the boundary of the article storage chamber 22 decreases due to the influence of the outside temperature, and the air in the boundary is cooled. Figure 5 As shown in FIG. 1( a ), condensation 100 occurs on the ceiling wall 5 at the boundary between the main body 3 and the door 15 .

[0073] When the condensation 100 grows, it separates from the ceiling wall 5 and falls, and is caught by the groove 70 formed by the lower dew receiving member 51. In addition, part of the enlarged condensation 100 passes through the inner wall 60 of the door 15 and is caught by the groove 70.

[0074] When the door 15 is opened, Figure 5 As shown in (b), the scraper member 52 moves in the opening direction along with the door 15. Here, since the upper end of the scraper member 52 is in contact with the ceiling wall 5, the scraper member 52 moves and wipes the ceiling wall 5, scraping off water droplets of condensation 100 adhering to the ceiling. The scraped water droplets are caught in the groove 70 formed by the dew-collecting member 51 below.

[0075] As described above, the scraper member 52 is arranged so that its upper end contacts the ceiling wall 5 of the main body 3. Since the upper end of the scraper member 52 contacts the ceiling wall 5, a load is applied to the scraper member 52.

[0076] In this embodiment, the lower portion of the scraper member 52 that does not protrude from the dew receiving member 51 is supported by the vertical wall 53 of the dew receiving member 51. Therefore, a load is applied to the portion of the scraper member 52 that protrudes from the dew receiving member 51. Therefore, when the door is opened, the upper end of the scraper member 52 moves along the ceiling wall 5, allowing the scraper member 52 to scrape out water droplets of condensation 100 adhering to the ceiling wall 5.

[0077] like Figure 5 As shown in (c), when the door 15 is opened, the condensation 100 on the ceiling wall 5 near the opening 11 is completely wiped off and enters the groove 70 formed by the dew receiving member 51 and the door 15.

[0078] Then, the water 101 collected by the water droplets flows along the longitudinal direction of the groove 70 along the slope and reaches the vicinity of the mounting side 17 of the door 15. The end of the dew receiving member 51 on the mounting side 17 side is the opening 61.

[0079] Therefore, part of the collected water 101 flows out from the installation side 17 side of the door 15, falls downward, and is received by a tray or the like not shown. The water 101 that is not drained and remains after the door 15 is closed is Figure 3 As shown, the liquid flows downward along the left side wall 8 of the main body 3 .

[0080] It should be noted that the water 101 collected when the door 15 is closed is Figure 3 As shown, the liquid flows downward along the left side wall 8 of the main body 3 .

[0081] In the present embodiment, a drainage hole 40 is provided on the bottom wall 6 of the article placement chamber 22 near the mounting side 17 of the door 15 .

[0082] Of the water 101 flowing out from the installation side 17 , the water flowing downward along the left side wall 8 falls near the drain hole 40 and is discharged from the drain hole 40 .

[0083] According to the environment forming device 1 of this embodiment, when the door 15 is opened, condensation on the ceiling wall 5 near the opening 11 is wiped off, thereby preventing water droplets from falling on the user and also preventing water from splashing onto items inside.

[0084] In addition, the hinge side of a swing door is generally difficult to notice. However, the environment forming device 1 of this embodiment collects condensed water and drops it to the installation side 17 side of the door 15, so the water is not conspicuous.

[0085] In the water guide member 50 described above, the inner wall 60 of the door 15 is used as a part of the groove 70, but as Figure 6 As shown in (a), the groove 70 may be formed only by the exposure member.

[0086] Right now, Figure 6 The water guide member 71 shown in (a) includes a first vertical wall 72 , a bottom wall 55 , and a second vertical wall 73 , thereby forming a groove 70 .

[0087] In the water guide member 50 described above, the scraping member 52 is strip-shaped. In the water guide member 50, the contact line of the scraping member 52 is linear, and the linear portion contacts the ceiling wall 5 to remove the condensation 100.

[0088] The scraping member 52 does not necessarily need to be in a belt shape, and may be in a comb shape or a brush shape.

[0089] exist Figure 6 In the water guide member 75 shown in (b), a brush-shaped scraping member 76 is used.

[0090] In the water guide 75, multiple fibers 77 contact the ceiling wall 5 to remove condensation 100. Furthermore, since condensation 100 adheres to the ceiling wall 5 due to intermolecular forces overcoming gravity, when the fibers 77 contact the condensation 100, the fibers 77 guide the condensation 100 away from the ceiling wall 5 and into the groove 70.

[0091] The cross-sectional shape of the groove 70 is not limited and may also be Figure 6 In other words, the bottom wall 85 of the leak-receiving member may be formed to be inclined from the vertical wall 53 toward the inner wall 60 of the door 15 .

[0092] In addition, the cross-sectional shape of the groove 70 may also be Figure 6 That is, the bottom wall 86 of the exposure member may be formed in a stepped shape from the vertical wall 53 toward the inner wall 60 of the door 15 .

[0093] exist Figure 6 (c) Figure 6 In the groove 70 shown in (d), the captured water 101 is collected in the lower region having a narrow cross-sectional area, so the water level becomes high and the water flows easily.

[0094] In the embodiment described above, the groove 70 is inclined in the width direction of the door 15 by installing the water guide members 50 , 71 , 75 in an inclined posture.

[0095] On the other hand, it is preferable that the upper ends of the scraping members 52 and 76 are in contact with the ceiling wall 5 over their entire lengths. Here, when the inclination angle of the groove 70 is large, the contact amount between the scraping member 52 and the ceiling wall 5 may be excessively different between the portion located on the upper side of the inclination and the portion located on the lower side.

[0096] In this case, it is preferable to change the extension (protrusion amount) of the scraping member 52 from the dew contact member 51 in the longitudinal direction so that the extension on the inclined lower side is larger than the extension on the upper side.

[0097] Alternatively, the vertical width of the scraping members 52 and 76 themselves may be varied in the longitudinal direction so that the width of the inclined lower portion is larger than the width of the upper portion.

[0098] Alternatively, it is recommended to adopt a structure in which the extension (protrusion amount) of the scraping member 52 from the dew contact member 51 can be adjusted by attaching the scraping member 52 or 76 through a longitudinally long hole or the like.

[0099] In the above-described embodiment, the groove 70 is inclined by installing the water guide members 50 , 71 , 75 in an inclined posture. However, the bottoms of the water guide members 50 , 71 , 75 themselves may be inclined in the longitudinal direction.

[0100] The total length L of the exposure member 51 may be shorter than the width WA of the opening 11 of the main body 3 by several mm to several tens of mm.

[0101] The doors 15 in the above-described embodiments are all swing doors, but they can also be applied as sliding doors by refining the shape.

[0102] Figure 7 An example in which a water guide member 81 is attached to a sliding door 80 is shown.

[0103] The sliding door 80 moves in the direction of the arrow along a track (not shown) to open the opening of the main body 3 .

[0104] The water guide member 81 includes a groove-shaped dew-receiving member 82 , and a short scraping member 83 is provided at an end portion in the longitudinal direction of the dew-receiving member 82 .

[0105] When the sliding door 80 is moved in the direction of the arrow to open the sliding door 80 , the scraper member 83 moves linearly to remove dew condensation on the ceiling wall 5 .

[0106] In the embodiment described above, the scraping members 52, 76, and 83 contact the ceiling wall 5 to remove condensation, but the present invention is not limited to this configuration. Alternatively, the scraping members 52, 76, and 83 may be installed so that their upper ends contact condensation droplets adhering to the ceiling wall 5, causing the droplets to fall off as the scraping members contact the droplets.
