- the second water-permeable porous body 36 approaches the upper frame 21 . Specifically, the second water-permeable porous body 36 approaches the heat-insulating porous body 25 . That is, when the left sliding door 30 moves, the gap H1 between the second water-permeable porous body 36 and the heat-insulating porous body 25 is the same as that of the second water-permeable porous body 36 when the left sliding door 30 is closed. and the adiabatic porous body 25 (FIG. 6).
- the left sliding door 30 moves to the right along the pair of rails 22a while maintaining the narrowed gap between the second water-permeable porous body 36 and the heat insulating porous body 25.

- Condensed water is generated on the upper frame 21 due to the temperature difference between the temperature inside the storage room and the outside air temperature. Condensed water is generated on the outer surface of the upper frame 21 and the surface of the heat insulating porous body 25 . The condensed water generated on the upper frame 21 gathers to form droplets, and then falls on the upper surfaces of the second water-permeable porous body 36 and the upper frame 31a.
- the condensed water falling on the second water-permeable porous body 36 passes through the second water-permeable porous body 36 and flows out to the upper surface of the upper frame 31a. Further, as described above, in the closed state of the left sliding door 30, the upper surface of the left sliding door 30 is inclined downward from above as it goes from right to left. Therefore, the condensed water that has flowed out to the upper surface of the upper frame 31a and the condensed water that has fallen from the upper frame 21 to the upper surface of the upper frame 31a is separated from the front, rear, and right sides of the left sliding door 30 by the pair of long portions 31a1 and the right frame 31c. It flows to the left without flowing down on the surface.
- the condensed water that flows with the upper surface of the upper frame 31 a facing left reaches the water-permeable porous body 35 .
- the condensed water that has reached the water-permeable porous body 35 passes through the water-permeable porous body 35 and flows out to the inside of the left frame 31b. Since the water-permeable porous body 35 has an open-cell structure as described above, it acts as a resistance against the flow of condensed water.
- the flow of condensed water is suppressed by the water-permeable porous body 35 . Therefore, the flow rate of the condensed water flowing from the upper surface of the upper frame 31a to the inside of the left frame 31b, that is, the flow rate per unit time is suppressed.
- the drain port 22c has the minimum size necessary to minimize the influence of the environment inside the machine storage room 50 on the inside environment. If the flow rate of condensed water per unit time is not controlled and a large amount of condensed water is supplied around the drain port 22c at once, the condensed water cannot smoothly pass through the drain port 22c and the lower frame 22 It spreads on the top. Once the condensed water spreads, the condensed water located far from the drain port 22c cannot move to the drain port 22c.
- the flow rate of condensed water per unit time is suppressed. Specifically, the flow rate is controlled to be less than or equal to the flow rate at which water can smoothly pass through the drain port 22c. Since the flow rate of the condensed water per unit time is suppressed by the water-permeable porous body 35, the condensed water does not remain on the lower frame 22 and is discharged from the drain port 22c. Therefore, the drainability of condensed water can be improved by the water-permeable porous body 35 .
- the material and size of the water-permeable porous body 35 are determined in such a unit that the flow rate per unit time of the condensed water passing through the water-permeable porous body 35 allows the condensed water to pass through the drain port 22c only by gravity. It is preferably determined and set so as to be equal to or less than the flow rate per hour.
- the second water-permeable porous body 36 approaches the heat insulating porous body 25 .
- the second water-permeable porous body 36 scrapes off droplets W of condensed water on the surface of the heat-insulating porous body 25, as shown in FIG. Therefore, when the left side sliding door 30 is opened and the sample or the like is taken out from the storage room, it is possible to prevent the condensed water from falling on the sample or the like.
- the right side sliding door 40 is configured to be bilaterally symmetrical with respect to the left side sliding door 30 .
- the right side stepped portion 22b corresponding to the right side sliding door 40 is provided so as to be deeper than the left side stepped portion 22b, when the right side sliding door 40 is closed, the upper surface of the right side sliding door 40 is positioned to the left side. It slopes from top to bottom as it goes to the right from the top. Therefore, the condensed water that falls on the upper surface of the right sliding door 40 passes through the water-permeable porous body 35 and flows out to the lower frame 22 via the inside of the right frame in the same way as the condensed water that falls on the upper surface of the left sliding door 30. .
- the second water-permeable porous body 36 attached to the right sliding door 40 is attached to the upper surface of the right sliding door 40 in the same manner as the second water-permeable porous body 36 attached to the left sliding door 30. Droplets of condensed water formed on the heat-insulating porous bodies arranged facing each other are scraped off.
- the present disclosure is not limited to the embodiments described so far. As long as it does not deviate from the gist of the present disclosure, a mode constructed by combining various modifications of the present embodiment is also included within the scope of the present disclosure.
- the upper frame 31a has the water-permeable porous body 35 and the second water-permeable porous body 36 attached to its upper surface, but the second water-permeable porous body 36 may not be attached.
- a porous body in which the water-permeable porous body 35 and the second water-permeable porous body 36 are combined and integrated may be attached.
- another porous body having water permeability may be further attached.
- the size of the gap between the second water-permeable porous body 36 and the heat-insulating porous body 25 when the left sliding door 30 moves, and the second water-permeable porous body 36 when the right sliding door 40 moves may be different.
- the gap between the second water-permeable porous body 36 and the heat-insulating porous body 25 is narrowed for the left sliding door 30 and the right sliding door 40 where dew condensation water is likely to occur. This makes it easier for the second water-permeable porous body 36 to scrape the condensed water out of the left sliding door 30 and the right sliding door 40 where condensed water is more likely to occur.
- the heat insulating porous body 25 may not be attached to the upper frame 21 . If the heat-insulating porous body 25 is not attached to the upper frame 21, the second water-permeable porous body 36 acts as the second water-permeable porous body 36 in the upper frame 21 when the left sliding door 30 and the right sliding door 40 move.
- the porous body 36 is formed so as to come close to the opposing portion and scrape off drops of condensed water.
- the water-permeable porous body 35 has an L-shaped shape (FIG. 2), but may have a linear shape as shown in FIG. Thereby, the production of the water-permeable porous body 35 can be facilitated. Moreover, when the water-permeable porous body 35 is formed in a flexible shape, it can be easily attached without being bent.
- the water-permeable porous body 35 formed in a straight line is arranged inside the left frame 31b. It faces the lower frame 22 so as to face the inner side of the left frame 31b without being exposed.
- the inside of the left frame 31b is a drainage channel through which the condensed water passes, but the drainage channel may also be provided inside the right frame 31c.
- the right frame 31c is provided in a cylindrical shape like the left frame 31b, and a water-permeable porous body is attached to the upper surface of the upper frame 31a so as to face the inside of the right frame 31c.
- drainage channels are provided both inside the left frame 31b and inside the right frame 31c, the upper surface of the left sliding door 30 does not tilt (that is, becomes approximately horizontal) in the closed state, corresponding to the left sliding door 30.
