置に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a constant temperature and constant humidity tank for conducting an environmental test on electric and electronic parts and the like placed in the tank with a constant temperature and humidity in the tank, and particularly, It relates to a tank ventilation device.

【従来の技術】恒温恒湿槽は、槽背部に加湿器、冷却器
及び加熱器等を備え、これらにより槽内を一定の温度と
湿度に保つようになっている。2. Description of the Related Art A constant temperature and constant humidity tank is provided with a humidifier, a cooler, a heater and the like at the back of the tank so that the inside of the tank can be kept at a constant temperature and humidity.

まで槽内温度の維持を図っているほどである。Of these, it is particularly important to maintain the humidity. For example, in the constant temperature and constant humidity chamber described in Japanese Utility Model Laid-Open No. 1-152242, a dehumidifier is provided outside the chamber, and the dehumidifier removes the gas in the gas surrounding the chamber The temperature inside the tank is maintained until the water is captured and taken in.
【0004】しかし、このようにして試験中、加湿を続
けているため、試験運転を停止しても湿気が槽内に残
り、これが原因で、恒温恒湿槽の槽内にはカビや異臭が
発生するという問題があった。However, since the humidification is continued during the test in this way, even if the test operation is stopped, the moisture remains in the tank, which causes mold and an offensive odor in the tank of the constant temperature and constant humidity tank. There was a problem that it occurred.

が、もとよりそうした手段では、短時間の乾燥が不可能
で、カビや異臭の発生を完全に防止することはできなか
った。Therefore, in some cases, the test operation of the constant temperature and constant humidity chamber is stopped and the opening / closing door on the front of the chamber is immediately opened to dry the inside of the chamber. By such means, it was impossible to dry for a short time, and it was not possible to completely prevent the generation of mold and offensive odor.

ある。In view of the above situation, the present invention proposes a ventilation device for forcibly ventilating the inside of a constant temperature and constant humidity tank that is stopped.
Thus, it is an object of the present invention to provide the comfortable test environment of the constant temperature and humidity chamber while preventing the above-mentioned mold and offensive odor.

る。That is, the feature of the present invention which meets the above-mentioned object is that an exhaust port and an intake port are opened in the ceiling wall of a constant temperature and humidity chamber, and the lower part of each of the exhaust port and the intake port is respectively. A damper that opens and closes at a predetermined angle is provided obliquely downward toward the inner wall of the tank, and an exhaust fan or an intake fan is provided above the exhaust port and / or the intake port.

駆動すると、槽内に気流が吸気口から流れ込み、排気口
から排出されることとなる。In the above structure, the two dampers are opened when the operation of the constant temperature and humidity chamber is stopped. This naturally opens the intake port and the exhaust port, but at this time, if an exhaust fan is provided at the exhaust port and this exhaust fan is driven, the airflow will flow into the tank from the intake port and the exhaust gas will be exhausted. It will be discharged from the mouth.

一掃される。By the way, since the damper is opened obliquely downward toward the inner wall of the tank, this air flow goes toward the inner wall of the tank on the inlet side along the inclination of the damper when entering the intake port. It flows from the side wall to the bottom of the tank, then rises on the opposite side wall of the tank, and goes out from the exhaust port along the inclination of the other damper. Therefore, the wall surface in the tank is dried in an extremely short time by the air flow, and the cause of mold and offensive odor is eliminated.

し最大に開放した状態でも30゜〜45゜である。At this time, it is preferable to open / close the damper (9) by a gad motor (M 1 ). As shown in the figure, the exhaust port (6) inside the tank (2) and the ceiling wall (5) is connected to the exhaust port (6). A gad motor (M 1 ) is hung down from the ceiling wall (5) and fixed to a position very close to the exhaust port (6) between the intake port (7) and the rotary shaft of this gad motor (M 1 ). One end of the damper (9) is attached. Since the gad motor (M 1 ) rotates in both forward and reverse directions at, for example, about 3 rpm, the damper (9) slowly rotates about the rotary shaft mounting portion. The rotation angle of the damper (9) is limited, and is 30 ° to 45 ° even when the damper (9) is fully opened with respect to the exhaust port (6).

First, when the control device confirms that the test operation in the constant temperature and constant humidity chamber is stopped and all the machines such as the humidifier are stopped (a), The gad motors (M 1 ) and (M 2 ) start rotating (b). Then, both dampers (9) and (15) are opened to a predetermined angle, the limit dog (10) of the exhaust side damper (9) contacts the open detection limit switch (11), and the switch (11) is turned on. Then, (C), the geared motors (M 1 ) and (M 2 ) stop, and the exhaust fan (8) rotates (D). This state continues while the test operation is stopped (e) until an operation command is externally issued to the machine (e). When an operation command is issued (G), the exhaust fan (8) first stops (G) along with the operation of the machine (H), and then the gad motors (M 1 ) and (M 2 ) move in the opposite direction. When the dampers (9) and (15) are closed by rotating to the full closed state, the closing detection limit switch (12) operates (L) and finally the gad motors (M 1 ) and (M 2 ) Stops. After that, while the machine is operating in the constant temperature and humidity chamber, the gad motors (M 1 ) and (M 2 ) and the exhaust fan (8) maintain this stopped state, and the constant temperature and constant humidity chamber performs the normal test operation. I do.

While is spinning. At this time, the exhaust side damper (9) and the intake side damper (15) are both in the tank (2).
It is opened at 30 ° to 45 ° toward the inner wall side, and moreover, both side parts (16), (1) of both dampers (9), (15).
6) is a bellows (1) with respect to the exhaust port (6) or the intake port (7)
7) and (17) are connected, the air flow generated by driving the exhaust fan (8) enters from the intake port (7).
After being blown onto the inner wall of the tank (2) along the inclination of the intake-side damper (15) and flowing down the side wall, the inner wall of the other tank (2) rises through the inner bottom of the tank (2). Finally, the flow goes out from the exhaust port (6) according to the inclination of the exhaust side damper (9). As a result, all the water adhering to the side wall in the tank (2) is dried by the air flow.

The bellows (17) connecting between both side portions (16) and (16) of (15) and the side edges of the exhaust port (6) and the intake port (7) constitutes the present invention. It is not always necessary, for example, each damper (9), (15)
If the opening angle of 10 ° to 15 ° is smaller than the above 30 ° to 45 °, the air flow entering from the intake port (7) without the bellows (17) is the inner wall of the tank (2). Almost all of them are sprayed on, and it is possible to obtain substantially the same operational effects as those described above.
