Further, according to the present invention, a dehumidifier is configured by storing a deliquescent drug packaged with a water-soluble and / or water-decomposable packaging material in a container including a moisture-permeable and water-impermeable member. 7. At this time, the packaged deliquescent drug is taken out from the gas barrier packaging material and then stored in a container containing a moisture-permeable and water-impermeable member. 8. The container of the dehumidifying device includes a lid and a container body, and the lid of the container is provided with a moisture-permeable and water-impermeable member, and the lid can be opened and closed and / or detachable from the container body. 9. A deliquescent drug packaged with a water-soluble and / or water-disintegrating packaging material is disposed above the container of the dehumidifier, and a deliquescent liquid reservoir of the deliquescent drug is disposed below the container. 10. The container of the dehumidifier is provided with a means for opening at least a part of the packaging bag for the deliquescent drug. 11. A fan is provided in the container of the dehumidifier. 12. The container of the dehumidifier is made of a biodegradable resin.

[0006]

According to the means for solving the present invention as described above, the following functions and effects can be obtained. 1. Since the deliquescent drug is packaged in a water-soluble and / or water-decomposable packaging material, a small-sized packaging bag is formed, and handling is facilitated. 2. Since the deliquescent drug is packaged, there is no danger or potential for dirt from direct handling by the operator. On the other hand, the packaging bag itself does not melt due to moisture absorption during use, so that there is no problem of post-processing of the bag. 3. In the case of a deicing agent, it can be provided in the form of a small-sized packaging bag containing the deliquescent drug, so that it can be easily used as a deicing agent for entrance doors, sidewalks and the like in ordinary households. 4. In the case of a dehumidifier, the above-described packaging bag containing the deliquescent drug can be repeatedly used, and it is sufficient to simply store it in a container including a moisture-permeable and non-permeable member. There is no need for any ancillary configuration that was required for conventional refilling, and the amount of waste can be significantly reduced.
This effect is further enhanced because the bag itself melts and disappears.
