Therefore, the air blown out from the outlet 20 after the temperature is adjusted to the set temperature comes into contact with the specimen 200 on the shelf 201 and exchanges heat, and the air after that comes into contact with the temperature sensors 40a, 40b, and 40c provided on the door 6. , 40d.

Therefore, it can be said that the temperature distribution on the inner surface of the door 6 (the surface on the test chamber 8 side) not only represents the temperature distribution of the door 6 but also the temperature distribution in the test chamber 8 . That is, the temperature distribution on the inner surface of the door 6 correlates with the temperature distribution in the test chamber 8 .
In the environmental test apparatus 1 of the present embodiment, the temperature variations detected by the temperature sensors 40a, 40b, 40c, and 40d provided on the door 6 are displayed on the display device 100, so that the temperature variations in the entire test chamber 8 can be detected. can be monitored.

It is desirable that the display on the display device 100 be visually appealing to the user, and that the rough temperature distribution inside can be understood at a glance.
For example, it is recommended to use an isothermal line connecting portions having the same temperature as shown in FIG. 10(a).
FIG. 10(b) is an example in which the temperature distribution is displayed by color coding. For example, areas with high temperatures are colored red, which implies high temperatures, and areas where temperatures are low, blue, which implies low temperatures.

Further, in the present embodiment, temperature variations in the test chamber 8 can be automatically eliminated.
In this embodiment, diffusion amount control means for remotely operating the diffusion means 41 and wind direction control means for remotely operating the wind direction means 43 are provided.
That is, it has a linear drive mechanism 87 for adjusting the substantial opening 76 of the diffusion means 41, and a linear drive mechanism (Y-direction side) 88 and a linear drive mechanism (X-direction side) 90 for adjusting the direction of the wind direction means 43. . In this embodiment, these are automatically driven by the control device 101 so as to eliminate temperature variations in the test chamber 8 .

That is, in this embodiment, the diffusion means 41 is provided in front of the blower 30 . The diffusion means (hood member) 41 has an opening (substantial opening 76) on its side surface. Therefore, part of the air blown by the air blower 30 is discharged laterally as indicated by the arrow in FIG. flow along 11. Further, the blown air flows along the top wall and side walls of the test chamber 8 and spreads to every corner of the test chamber 8 .

Particularly in this embodiment, the control device 101 controls the linear drive mechanism 87 to rotate the outer cylinder 51 and increase or decrease the substantial opening area of the side surface of the diffusion means (hood member) 41 . That is, the environmental test apparatus 1 of this embodiment has an opening degree control means (diffusion amount control means) for substantially changing the opening degree of the opening. The environmental test apparatus 1 of this embodiment also includes a plurality of temperature sensors 40a, 40b, 40c, and 40d.
For example, when a high temperature test is performed in the test chamber 8, when it is determined that the temperature at the side of the test chamber 8 is low from the analysis of the temperatures detected by the temperature sensors 40a, 40b, 40c, and 40d, the diffusion means The opening area of the substantial opening 76 of the (hood member) 41 is automatically widened. Conversely, when the temperature of the side portion of the test chamber 8 is high, the substantial opening 76 is automatically narrowed.
Further, when a low-temperature test is performed in the test chamber 8 and it is determined from the analysis of the temperatures detected by the temperature sensors 40a, 40b, 40c, and 40d that the temperature of the side portions in the test chamber 8 is high, the side portions The opening area of the substantial opening 76 of the diffusing means (hood member) 41 is automatically widened so that the air blows around the entire area, and when the temperature of the side part in the test chamber 8 is low, the amount of air blowing to the side part is reduced. Substantial opening 76 of diffusing means (hood member) 41 is automatically narrowed to limit.

Thus, in the environmental test apparatus 1 of the present embodiment, the opening degree control means for changing the opening degree of the substantial opening 76, the plurality of temperature sensors 40a, 40b, 40c for measuring the temperature distribution in the test chamber 8, 40d, and the opening degree control means has a function of changing the opening degree of the substantial opening 76 in accordance with the temperatures detected by the temperature sensors 40a, 40b, 40c, and 40d.

In the above-described embodiment, the opening degree of the opening 76 is changed according to the temperature detected by the temperature sensors 40a, 40b, 40c, and 40d provided on the door 6. is provided, and the degree of opening of the substantial opening 76 may be changed according to the temperature detected by this temperature sensor.

Further, as described above, this embodiment has a wind direction control means for remotely controlling the wind direction means 43 .
That is, in this embodiment, the wind direction means 43 is provided in front of the blower 30 . By moving the operation shaft 78, the wind direction means 43 swings and can change the wind direction of the blower 30 in the X and Y directions.
In particular, in this embodiment, the operation shaft 78 can be moved by the linear drive mechanisms 88 and 90 to automatically change the wind direction of the blower 30 in the X and Y directions.
For example, when a high temperature test is performed in the test chamber 8, the airflow direction means 43 can be automatically directed so that the air blows to a region of the test chamber 8 where the temperature is low. That is, by referring to the temperatures detected by the temperature sensors 40a, 40b, 40c, and 40d provided on the door 6, the airflow direction means 43 can be automatically directed so that the airflow spreads over the areas of the test chamber 8 where the temperature is low.
In the case of performing a low-temperature test in the test chamber 8, the temperature detected by the temperature sensors 40a, 40b, 40c, and 40d is referred to, and the wind direction means 43 is automatically adjusted so that the air blows to the high-temperature region in the test chamber 8. can be aimed.

As described above, in the environmental test apparatus 1 of the present embodiment, the temperatures detected by the plurality of temperature sensors 40a, 40b, 40c, and 40d are referred to, and an area where the temperature detected by the temperature sensors is lower than the set temperature of the test chamber 8 is detected. Alternatively, the wind direction means 43 can be directed to a high area to blow air intensively to the area.

It is also recommended that the number of revolutions of the driving motor 33 of the blower 30 be variable by inverter control or the like. That is, it is recommended to have an air volume adjusting means by inverter control or the like.

As described above, in the environmental test apparatus 1 of this embodiment, the temperature of the air after heat exchange with the specimen 200 is detected by the temperature sensors 40a, 40b, 40c, and 40d.
Here, if there is a large difference between the temperature of the air adjusted by the air conditioning unit 15 and the temperature of the air detected by the temperature sensors 40a, 40b, 40c, and 40d, the amount of heat and the amount of cold heat of the air adjusted by the air conditioning unit 15 is considered inappropriate.

Assuming that the test piece 200 itself does not generate heat, for example, when a high-temperature test is performed, the temperature of the air detected by the temperature sensors 40a, 40b, 40c, and 40d is higher than the temperature of the air blown from the outlet 20. If the temperature is excessively low, the amount of heat in the air adjusted by the air conditioning unit 15 is considered to be insufficient.
In this case, for example, the number of rotations of the blower 30 is increased to increase the amount of air blown out from the outlet 20 .
Alternatively, the temperature of the air adjusted by the air conditioning unit 15 is corrected upward to raise the temperature of the air blown out from the blowout port 20 .

The same is true when a low-temperature test is performed. is increased to increase the amount of air blown out from the outlet 20. - 特許庁
Alternatively, the temperature of the air adjusted by the air conditioning unit 15 is corrected downward to lower the temperature of the air blown out from the blowout port 20 .

When the test piece 200 generates heat and a high temperature test is performed, the temperature of the air detected by the temperature sensors 40a, 40b, 40c, and 40d is higher than the temperature of the air blown out from the outlet 20. In some cases. In this case, the temperature of the air adjusted by the air conditioning unit 15 is corrected downward, and the temperature of the air blown out from the outlet 20 is lowered.
