1 and 2 show the outer shape of a thermo-hygrostat which is an example of an environmental device. The thermo-hygrostat is a test tank 2 as an environment chamber in which a sample to be subjected to an environmental test is placed as an object and is controlled in temperature and humidity, which is enclosed by a heat insulating layer 1 as an outer wall, and FIG. As shown in the enlarged view of FIG. 1, the apparatus has a wick pan 3, a wick 4 for sucking water therein, and a detection end 5 on which the wick is placed, and a wet-bulb temperature detecting unit 6 for detecting a wet-bulb temperature.

The wet-bulb temperature detector 6 is disposed near the heat insulating layer 1 and has a through-hole 7 which is large enough for humans to access in the present embodiment. And a small door 8 as a closing member large enough to open and close the door. The through-hole 7 and the small door 8 correspond to the position of the wet-bulb temperature detecting unit 6, and the wick 4 covered on the detecting end 5.
To a position where it can be easily attached and detached. Therefore, as shown in FIGS. 1 and 2, when the wet-bulb temperature detecting unit 6 is located above and at a position close to the door 1 a in the heat insulating layer 1, the through hole 7 is placed above the door 1 a. When provided near the side wall 1b of the heat insulating layer 1 as shown in FIG. 2, the through hole 7 is also provided in that portion.

When the through-hole 7 is made large enough for a human hand, the human hand can easily and quickly remove the wick 4 from the detection end 5 and take it out. or,
If the small door 8 is provided and the wick 4 is exchanged by opening and closing the small door 8 as described above, the original door 1a does not need to be opened and closed for wick exchange, so that the atmosphere in the test tank 2 is less disturbed. In addition, the through-hole 7 does not necessarily need to be large enough for human hands. By making this a small diameter hole, for example, a knob portion may be provided on the wick 4, the portion may be pinched with an appropriate holding tool, and the wick 4 may be attached to or detached from the detection end 5. In that case, the operation is somewhat difficult, but the disturbance in the atmosphere in the test tank is further reduced.

FIG. 3 shows the configuration of a thermo-hygrostat provided with the wet-bulb temperature detecting section 6 in the air-conditioning room and the access state when the wick is replaced. In the thermo-hygrostat of this example, the wet-bulb temperature detector 6
Is provided in the air conditioning room 9. A humidifying heater 10, a cooler 11, which is cooled by a refrigerant sent from a refrigeration unit (not shown), a heater 12, a blower 13 for circulating air, and the like are arranged in the air-conditioning room 9 to adjust the temperature and humidity.

Reference numeral 14 denotes a device for supplying water to the wick pan 3, and reference numeral 15 denotes a register for adjusting the direction of air blowing.

The through hole 7 and the small door 8 are provided at positions where the wick 4 covered on the detecting end 5 can be easily attached and detached corresponding to the position of the wet bulb temperature detecting section 6 as in the example of FIG. 3 (a)
Is provided at the upper part of the side wall 1b in the case of the constant temperature and humidity chamber, and is provided at the end of the door 1c of the lower air-conditioning room 9 in the case of FIG. If the wet-bulb temperature detector 6 is provided in the air-conditioning room 9 as in this example, even if outside air enters through the through-hole 7 at the time of wick replacement, the air is mixed with the conditioned air, so that the outside air is applied to the internal test object. There is no direct hit. Therefore, the test conditions are hardly disturbed by the wick exchange.

FIG. 4 shows an example in which the detection end 5 is of a plug type. The detection end 5 is a plug, and is formed on the wick pan 3 and has a connector 51 to which the lead wire 5a is connected.
It is removable. As a result, it is possible to move from the position at the time of detection in the internal test tank 2 or the air conditioning room 9 (hereinafter, represented by “test tank 2”) to the outside 100 of the heat insulating layer 1. By doing so, the wick 4 can be taken in and out together with the detection end 5 from the through-hole 7, so that the wick can be exchanged with the outside 100, and workability is improved. Further, since the detection end 5 and the connector 51 can be attached and detached by inserting and pulling out, the operation is also easy.

In this device, the support plate 81 can be easily attached and detached, and the attachment / detachment allows the detection end 5 and the wick 4 covering the detection end 5 to be automatically taken in and out, and the wick can be exchanged externally, so that operability and workability are good. . Further, since the area of the through hole 7 is reduced, the disturbance of the atmosphere in the test tank 2 at the time of wick replacement is further reduced. Furthermore, since the wick pan 3 is fixed, water inside does not spill due to vibration or the like. The apparatus of FIG. 6 is the same as the apparatus of FIG. 5, except that the wick 3 is stopped in the test tank 2 and
It does not protrude to the 0 side. In this case, it is necessary to bend the wick 4 to pass through the through-hole 7, so that the through-hole 7 is L-shaped as shown. Then, in order to prevent the wick 4 from being inserted into the wick pan 3 in a distorted shape, an oblique cut portion 4a is formed at the tip of the insertion side, and the wick 4 is smooth as shown in FIG. The wick pan 3 is bent into the through hole 7, passes through the through hole 7, and is restored to the original shape in the wick pan 3. In this device, since there is no protrusion on the outside 100 side and the water surface of the wick pan 3 does not open on the outside world, conduction of the inside and outside air is further reduced.

In the apparatus shown in FIG. 7, the support plate 81 of the apparatus shown in FIG.
And a front end cover 3b and a rear end cover 3c are formed at both ends of the wick pan 3 so as to extend to the upper part. The detection end 5 is U-shaped and is slidably supported by the covers 3b and 3c. I have. Similarly, an angle-shaped through hole 7 is opened in the rear end cover 3c and the heat insulating tank penetration portion, and a wick 4 is placed on one end of the detection end 5 and a stopper 82 fixed at the other end is also bent at an angle. By supporting the plate 83 and inserting and removing the detection end 5, the wick 4 is put in and out, and the through hole 7 is opened and closed. That is, also in this example, the detection end 5 is movable between the detection position in the test tank 2 and the outside 100, is attached to the stopper 82 serving as a closing member, and is opened and closed together with the wick 4 by opening and closing. . In this case, the same operation and effect as those in FIG. 6 can be obtained, and the structure can be simplified. Further, the dry-bulb temperature detection sensor 20 can be disposed at the position shown in the drawing by utilizing the U-shaped portion of the detection end 5. In this case, from the stopper plate 83, the lead plugs 5a and 20a for detecting the wet bulb temperature and the dry bulb temperature are led out.

The apparatus shown in FIG.
e, a cylindrical member 85 having a support 84 for supporting the detection end 5 at the tip is inserted as a closing member, and the cylindrical member 85 is fixed with a screw cap 86. Is formed. As a result, the detection end 5 can be moved between inside and outside of the test tank 2 by attaching and detaching the cylindrical body 85. When the cylindrical body 85 is inserted, the wick 4 covered on the detection end 5 enters the wick pan 3 fixed inside as shown. Also in this device, the wick 4 can be taken out together with the detection end 5 by removing the cap 86 and pulling out the cylindrical body 85, so that the wick can be easily replaced.

FIGS. 9 to 11 show examples in which the detection end 5 is formed integrally with the wick pan 3 or both are separately attached to the closing member so that they can be moved as a whole. .

In the apparatus shown in FIG. 9, the wick pan 3 and the detection end 5 are supported by a small door 8, and when the small door 8 is opened and closed, these move between the inside and outside of the test tank 2, and the wet bulb temperature is automatically adjusted. The detection unit 6 can be set at the equipment position and the take-out position. In this apparatus, for example, a pivot portion rotatably connecting the heat insulating layer 1 and the small door 8 is used for supplying water to the wick pan 3 and taking out the lead wire 5 a of the detection end 5. Even with this device, the wick can be easily exchanged outside. In addition,
In this example, the wick pan 3 and the detection end 5 are separately attached to the small door 8, but the wick pan and the detection end may be integrated and attached to the small door 8.

In the apparatus shown in FIG. 10, a cylindrical through-hole 7 is formed in the heat insulating layer 1, and a cylindrical lid 87 as a closing member to which the wet-bulb temperature detecting section 6 is attached is fitted into the hole. A slide shaft 88 is fixed to the cover 87. When the cover is attached, the slide shaft 88 is inserted into a small hole penetrating through the heat insulating layer 1 to prevent the cover 87 from rotating or falling off, and to detect the wet bulb temperature. The part 6 is positioned. Also in this example, the wick pan and the detection end may be integrated and attached to the lid 87. Further, the lid 87 may be square.

FIG. 11 shows an example in which the detection end 5 and the wick pan 3 are integrated so that they can be taken in and out of the test tank 2 to the outside 100. In this device, a rim 7a is attached to the through hole 7 of the heat insulating layer 1, a lid 87 is inserted into the integrally formed wick pan 3, the lid 87 is fitted to the rim 7a, and a support fixed to the flange portion of the rim 7a inside the tank.

FIG. 12 shows a control example at the time of wick exchange.
The thermo-hygrostat includes a temperature-humidity control unit 50 as humidity control means for controlling the humidity of the environment chamber, and a temperature-humidity control unit that controls humidity under predetermined conditions in place of the detection value of the detection end 5. An auxiliary control unit 70 as a wick exchange operation means for correcting the control of the small door 50 and a small door open / close switch 60 for detecting the opening and closing of the small door 8 as a wick exchange start time input means for inputting the start of the wick exchange. Have. In this embodiment, a mode selection input unit 61 for selecting an operation mode is also provided.

In this embodiment, the auxiliary control unit 70 includes a determination unit 71 for determining an operation state, a mode selection unit 72 for selecting an operation mode, a save operation output unit 73, and a constant value operation output unit 7.
4, an operation stop output unit 75, a timer 76, and the like.
Not all of these are essential,
Depending on the type and contents of the environmental device, the demands in driving operation, and the like, in the actual environmental device, these control units or other control units are appropriately selected.

As the wick replacement time input means, it is desirable to use a means such as an open / close switch 60 which automatically operates like a limit switch which operates when the small door 8 is opened and closed to replace the wick. It may be a manual switch that is turned on / off by a person at the time of replacement. Judgment unit 7
1) In order to perform the optimal wick replacement operation in accordance with the operating condition of the thermo-hygrostat at the time of wick replacement, the wick replacement is in a steady operation in which the temperature and humidity are kept constant or the temperature and humidity are increased. Alternatively, it is determined whether or not a transition operation for lowering is being performed. For example, if a preservation operation that maintains the operation state during the transition operation is performed, the temperature and the humidity exceed the set values and run away.

The mode selecting section 72 selects a control method which is set in advance so as to minimize the disturbance generated when the wick is replaced, based on the judgment of the steady operation or the transition operation by the judging section 71. For example, when the determination unit determines that the operation is a steady operation, based on the temperature / humidity set value at this time, from the control table for constant temperature and humidity stored in advance, the humidification and heating amount of the heater, the refrigerating capacity, etc. The control data is read out and the storage operation is controlled. In this case, the control data for the constant temperature / humidity operation stored in advance may take into account a correction value that takes into account even relatively small disturbance of the temperature / humidity control caused by opening the small door.

If the determination unit determines that the operation is the transition operation, and if "stop operation" is selected, the air conditioning control including the humidity control in the environment room is stopped until the wick exchange mode is reset. If "constant value operation" is selected, control data for maintaining the set value from a previously stored control table based on the temperature and humidity set value at that time (may be the same as the control table for constant temperature and humidity) Is read and controlled. At this time, instead of the control for maintaining the set value, the control for maintaining the measured value or the control for generating a predetermined temperature / humidity gradient may be performed. Further, the heat load in the environmental chamber is calculated from the temperature / humidity change pattern, and based on each operation data at that time, control is performed so that all subsequent operations are performed as estimated operations based on the calculated values. Operation control "may be adopted. The timer 76 measures and outputs the time required to open and close the small door 8 for wick exchange.

FIG. 13 shows an example of a control flow of the above-described auxiliary control unit. When the small door 8 is opened to start the wick replacement work, the small door opening / closing switch 60 is turned on (S-2). Based on the mode selection (S-1) previously selected by the operator in the mode selection unit 72 and the determination of the operation state of the determination unit 71 (S-3), the various operation controls (S -4, S-9). At the same time, the timer 76 is started to determine whether the switch 60 is turned off or the time is up (S-5, 6, 7). If the time is up, it is determined that the operator has forgotten to press the switch, and the wick exchange mode is forever set. An alarm is displayed to prevent the information from being held (S-7, 8). If switch off is detected after the timer starts, the wick exchange mode is reset to prepare for the next operation (S-10).

In order to reliably manage the timing of wick replacement, a timer linked to the open / close switch 60 is provided, and the time since the last time the open / close switch 60 was turned off is counted. In addition, a method of warning the operator, a method of detecting the deterioration of the wick itself and performing an abnormal output, or the like can be used.
