Description

[Detailed Description of the Invention] The present invention relates to a box-type desiccator designed to minimize the exchange of dehumidified air with the atmosphere when taking samples in and out.

Currently, various types of desiccators are widely used as experimental items in laboratories and the like, and large box-type desiccators that can store a large number of samples are also becoming popular. This type of desiccator has a single opening/closing door on the front of the main unit, and inside the desiccator, there are multiple shelves for storing samples arranged above and below. The entire desiccator is dehumidified using a dehumidifying agent such as silica gel through the ventilation holes in each shelf. in this way,
In a conventional box-type desiccator, samples on each shelf are taken in and taken out using a single opening/closing door, so when samples are exchanged, the dehumidified air in the entire sample chamber is replaced with outside air. Regardless of the number of samples being taken in or taken out, exchanging the dehumidified air in the entire desiccator with outside air exposes the sample to outside air more than necessary, which is not desirable for the original purpose of the desiccator.

The present invention solves the above problems by partitioning the desiccator body into multiple sample chambers with shelf boards, providing an opening/closing door for each sample chamber, and further adding a dehumidifier to the sample chamber when the opening/closing door is closed. The shelf board is characterized in that a communicating ventilation hole is provided in the shelf board.

Hereinafter, the present invention will be explained in detail using the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention. In FIG. 1, the interior of the desiccator main body 3 is vertically partitioned into a plurality of sample chambers by a plurality of shelf boards 4, 4, . Therefore, it is attached to the desiccator main body 3 so that it can be opened and closed. Furthermore, as shown in FIG. 2, each shelf board is provided with a ventilation hole 5 that communicates each sample chamber with the dehumidifier 10 at the bottom of the main body, and two shutters 6, 6 is slidably installed, and the shutters 6, 6 are biased by a spring 7 in the direction of opening the ventilation hole 5 of the shelf board. On the other hand, as shown in Figure 3,
The inside of the door 1 is provided with a projection 8 which pushes the projections 9 of the shutters 6, 6 inward to open the ventilation hole 5 by the shutters 6, 6 when the door 1 is closed. Further, 11 is a rubber seal for airtightness attached to the periphery of the door 1, and 12 is a clasp of the door 1.

In the embodiment, in order to take out a stored sample, only the opening/closing door of the sample chamber storing the sample is opened and the sample is taken out. In that case, the doors of the other sample chambers do not need to be opened, so they remain closed, and the samples on the other shelves are not exposed to the outside air. Furthermore, when the door 1 is closed, the protrusion 8 attached to the door 1 changes to the protrusion 9 attached to the shutter 6.
is pressed, the ventilation hole 5 of the shelf board 4 opens, the sample chamber communicates with the dehumidifier through the ventilation hole 5, and the air inside the sample chamber is dehumidified. Further, when the door is opened, the protrusion 8 of the door 1 comes off from the protrusion 9 of the shutter 6, the shutter 6 is moved by the spring 7, and the ventilation hole 5 of the shelf board 4 is closed as shown in FIG. Only the sample chamber with the opening/closing door 1 open is open to the outside air. In this case, the other shutters are open, but each sample chamber is separated by a shelf, so the air in the chamber opened to the outside air is exchanged with the outside air, and the air in the other chambers is exchanged with the outside air. Never. In addition, the shelf board can be inserted and removed, and several opening/closing doors may be connected and used as one opening/closing door, and by using this method, it is possible to store large samples.

Therefore, according to the present invention, it is possible to reduce the amount of air exchanged with outside air when taking out a sample, and moreover, it is possible to expose only the sample to be taken out to outside air, which has the effect of allowing the desiccator to fully demonstrate its original function. It is something that you have.
