ある。(Means for Solving the Problems) The present invention has been proposed to solve the above problems, and its gist is to cool, dehumidify, and reheat air extracted from a constant temperature and humidity chamber. In the constant temperature and constant humidity apparatus that circulates again in the constant temperature and constant humidity chamber, a part of the reheated air is accelerated to generate air along the boundary surface between the test space and the low humidity space which is limited to the constant temperature and constant humidity. A constant temperature and constant humidity apparatus characterized in that an air blower for blowing out in a curtain shape is provided and a means for jetting water vapor is provided in the test space.
空気吹出器から増速された空気の一部をバイパスさせて
上記空気吹出器が上記供試空間に対向する面に沿って吹
き出すスリットを設けることができる。It is possible to provide a slit that blows out a part of the air accelerated by the air blower and blows out along the surface of the air blower facing the test space.

所望の湿度に維持される。(Operation) Since the present invention has the above-mentioned configuration, the test space and the low humidity space are limited by the air curtain blown from the air blower into the constant temperature and humidity chamber, and only this test space has the desired humidity. Maintained at.
増速された空気の一部をスリットから吹き出せば、空気
吹出器が供試空間に対向する面に結露するのを防止でき
る。By blowing out a part of the accelerated air from the slit, it is possible to prevent dew condensation on the surface of the air blower facing the test space.
(実施例) 本考案の1実施例が第1図及び第2図に示されている。(Embodiment) One embodiment of the present invention is shown in FIGS. 1 and 2.
フィルター10の出口側に空気吹出器11が取り付けられ、
この空気吹出器11は水平な下部板11aと後流側に行くに
従って下降する上部板11bからなり、その入口から出口
に向かって流路断面積が次第に小さくなるように構成さ
れている。An air blower 11 is attached to the outlet side of the filter 10,
The air blower 11 is composed of a horizontal lower plate 11a and an upper plate 11b that descends toward the downstream side, and the flow passage cross-sectional area gradually decreases from the inlet to the outlet.

気の一部はバイパスして下部板11aに設けられたスリッ
ト16を経て下部板11aの下面に沿って供試空間14内に吹
き出される。Then, a part of the air that has passed through the filter 10 enters the air blower 11, and is gradually accelerated in the process of passing through the air blower 11 to become an air curtain 12, which is a low humidity space 13 in the constant temperature and humidity chamber 1.
And it is blown out along the boundary surface 15 of the test space 14. Then, the steam 9 generated in the humidifier 7 is ejected into the test space 14. A part of the air accelerated by the air blower 11 is bypassed and blown into the test space 14 along the lower surface of the lower plate 11a through the slit 16 provided in the lower plate 11a.
他の構成及び作用は第3図に示す従来のものと同様であ
り、対応する部材には同じ符号が付されている。Other configurations and operations are similar to those of the conventional one shown in FIG. 3, and corresponding members are designated by the same reference numerals.
しかして、エアカーテン12によって恒温恒湿室1が低湿

もに低湿空間13内に設置されている機器類の故障を防止
できる。また、低湿空間13内の雑菌等が供試空間14内に
浸入しないので供試空間14を清浄に維持できる。Then, the constant temperature and humidity chamber 1 is partitioned by the air curtain 12 between the low-humidity space 13 and the test space 14, and only the space in the test space 14 needs to be maintained at high humidity. Therefore, the operating cost of the constant temperature and constant humidity device can be reduced. Since the high-humidity air in the test space 14 does not enter the low-humidity space 13, it is possible to prevent dew condensation on the wall surface of the low-humidity space 13 and prevent breakdown of devices installed in the low-humidity space 13. . In addition, since bacteria and the like in the low humidity space 13 do not enter the test space 14, the test space 14 can be kept clean.

ある。Further, the water vapor 9 jetted into the test space 14 is slit 16
Since it is prevented from contacting the lower surface of the lower plate 11a by the air flow ejected from the dew condensation, dew condensation on the lower surface of the lower plate 11a is prevented. As a result, the amount of water vapor 9 to be supplied to the test space 14 can be reduced, and at the same time it is possible to prevent the generation and multiplication of various bacteria on the lower surface of the lower plate 11a. Needless to say, the structure of the air blower 11 is not limited to the illustrated structure as long as the number and mounting positions of the air blowers 11 can be selected according to the arrangement of the test space 14 and the air can be accelerated and blown out as an air curtain.

できる。(Effect of the Invention) In the present invention, since the test space and the low humidity space are limited by the air curtain blown from the air blower into the constant temperature and humidity chamber, it is sufficient to humidify only the test space. It is possible to reduce the operating cost of the moistening device and prevent breakdown of the analyzer, sample handling equipment, etc. arranged in the low humidity space.
