Description

[Detailed Description of the Invention] This invention relates to a humidity control device that prevents deterioration of a moisture absorbent.

Conventionally, a humidity control device having a configuration as shown in FIG. 1 has been used to heat a crucible, cool it naturally in a hygroscopic atmosphere, and measure the rate of weight loss.

In this conventional humidity control device, the lid 2 is opened and closed, and the fixing plate 3
The fixed plate 3 is configured to place the humidity controlled member 10 on the
Moisture is absorbed by the moisture absorbent 9 filled in the lower part of the container.

In such a conventional humidity control device, the humidity control target member 1
Since the moisture absorbing agent 9 comes into contact with the atmosphere each time the moisture conditioner 9 is put in and taken out, when a plurality of humidity conditioned members 10 are to be subjected to humidity conditioning, the effectiveness of the moisture conditioning agent 9 is reduced because the sample is taken in and out frequently. There was a drawback.

This invention was made in order to eliminate the above-mentioned drawbacks, and the object is to provide a humidity control device that prevents the moisture absorbent from absorbing moisture in the atmosphere.

An embodiment of this invention will be described below based on the drawings. FIG. 2 is a front sectional view of a humidity control device showing an embodiment of this invention. In the figure, reference numeral 1 denotes a container in which a humidity-controlled member 10, which will be described later, is housed, and is provided with a flange 1a constituting a sealed portion. Reference numeral 2 denotes a lid provided with a flange 2a facing the flange 1a, and an opening 2b is provided at the center of the flange 2a, which bulges from the inner circumference toward the center. 2c is a filling port provided in the lid 2, and 2d is a plug for the filling port. A fixing plate 3 is connected to the side wall of the lid 2 at a predetermined distance from the brim 2a, and has a plurality of holes 8a and a connecting hole in the center. 4 is a cylindrical fixing shaft that connects the opening 2b and the connection hole of the hole fixing plate 3; 5 is a square placed on the fixing plate 3, and the eyes have a predetermined size. A movable plate 6 faces the fixed plate 3, and is provided with a plurality of holes 6a that communicate directly with the holes 3a.The holes 6a are arranged so as to be able to close the holes 3a by rotating the movable plate 6. A movable shaft 7 is connected to the center of the movable plate 6 and is inserted through the fixed shaft 4 to form a predetermined sealing portion. 8 is a knob provided at the end of the movable shaft 7, and 9 is a moisture absorbent filled between the lid 1 and the fixed plate 3, which is sealed with a plug 2d inserted into the filling port 2c. Reference numeral 10 denotes a humidity-controlled member housed in the container 1.

Next, the operation will be explained. Humidity control member 10
3 and 4 are plan views of the fixing plate 6 seen from inside the lid, and as shown in the figure, the knob 8
by rotating the hole 6a of the movable plate 6 and the hole 8a of the fixed plate 3.
The inside of the container 1 and the moisture absorbent 9 are connected to each other by being arranged so as to communicate directly with each other. When the humidity adjustment is completed, the knob 8 is rotated again so that the hole 3a of the fixed plate 3 is sealed by the movable plate 6, as shown in FIG. This isolates the moisture absorbent 9 from the atmosphere and prevents it from absorbing moisture.

If the connection between the movable plate 6 and the movable shaft 7 in the above embodiment is a screw connection, manufacturing will be further facilitated.

According to this invention, the lid that seals the container is filled with a moisture absorbent, and the movable plate blocks the moisture absorption member from coming into contact with the atmosphere, thereby preventing deterioration of the moisture absorbent during periods other than humidity adjustment. This has the effect of significantly extending the life of the moisture absorbent.
