Hereinafter, an example of the ossuary chamber ventilation apparatus according to the embodiment of the present invention will be described by taking as an example the case of a Japanese tomb provided with an ossuary chamber on the ground.

The osteotomy ventilator of Example 1 will be described with reference to FIGS. 1 to 4 (particularly, corresponding to claims 4 and 5).
FIGS. 1A to 1C are a rear view, a side view, and a plan view, respectively, of a Japanese grave in which Example 1 of the ossuary chamber ventilation apparatus according to the embodiment of the present invention is installed. FIG. 2 is a block diagram illustrating a configuration of the ossuary chamber ventilation apparatus according to the first embodiment. FIGS. 3A and 3B are a front view and a side view, respectively, of the ossuary chamber ventilation apparatus of the first embodiment. 4 (a) and 4 (b) are a partially enlarged view of the cross section taken along line XX of FIG. 1 (c) and a cross sectional view taken along line YY of FIG. 1 (a), respectively. In FIGS. 3A and 3B, illustration of a part of the wiring and the solar cell panel is omitted.

As shown in FIGS. 1 (a) to 1 (c), the ossuary chamber 1 is a space surrounded by the root stone 2, the lower bedstone 3, and the headstone 4 arranged below the meteorite 5. Ventilation holes 6a to 6c are formed in the back and side surfaces.
The ossuary ventilator of the present embodiment includes a ventilation unit 7 inserted into the ventilation hole 6a, solar cell panels 8a and 8b installed on the upper surface of the capstone 4, and solar cell panels 8a and 8b with a motor 13 (FIG. Wiring 9 connected to 2), a control unit 18 (FIG. 2), and a sensor 20 (FIG. 2) are provided. Moreover, the sensor 20 detects the output voltage of the solar cell panel 8a as shown by the arrow A in FIG. 2, and the control unit 18 determines the operation of the storage battery 19 built in the solar cell panel 8b based on the detection result. I have control. Specifically, the storage battery 19 is charged by the solar battery panel 8b as indicated by an arrow B while the solar battery panel 8a supplies power to the motor 13, and the sensor 20 outputs the output voltage of the solar battery panel 8a. Is detected to be below the set value, a detection signal a is sent to the control unit 18. And the control part 18 which received the detection signal a sends the command signal b to the storage battery 19, and the storage battery 19 supplies electric power to the motor 13 as shown by the arrow C according to the command signal b.

  As shown in FIGS. 3 (a) and 3 (b), the ventilation unit 7 constituting the ossuary chamber ventilation apparatus of the present embodiment includes a fixture 10 having a substantially cylindrical shape, and an opening 10b inside the fixture 10. A fan 12 inserted from the side of the fan 12 and a motor 13 connected to the fan 12 are provided. The wiring 9 is detachably connected to the motor 13 and the solar battery panels 8a and 8b via connectors (not shown). The wiring 9 is covered with a synthetic resin having heat resistance and water resistance. The solar cell panels 8a, 8b and the portions where the motor 13 and the wiring 9 are connected to each other by the connector are waterproofed, and the ventilation unit 7 is connected from the inside of the ventilation hole 6a during inspection and replacement. A reserve length is formed so that it can be pulled out easily toward the outside.

At one end of the fixture 10, a flange-like locking portion 10a that locks to the edge of the ventilation hole 6a when the ventilation unit 7 is inserted into the ventilation hole 6a is formed. A metal or plastic rain protection cover 11a covering approximately half of the portion 10a is attached. The rain protection cover 11a has a 1/4 spherical shell shape, and one of the 1/2 arc-shaped end edges is joined to the end edge of the locking portion 10a so as not to cause a gap for rain water to enter. ing. In this case, an opening of the rain protection cover 11a is formed in a direction perpendicular to the cylindrical axis of the fixture 10. That is, the rain protection cover 11a is installed at the end of the fixture 10 so as to cover a part of the opening 10b of the fixture 10 while ensuring air permeability.
A metal or plastic disk-shaped insect repellent cover 11b having a plurality of louvers is fitted into the opening 10b of the fixture 10. The louver is variably attached at an angle, and the width of the substantially strip-shaped gap formed by the louver can be adjusted by changing the angle of the louver. Therefore, the rotation state of the fan 12 can be visually recognized from the outside via the insect repellent cover 11b, and visual inspection can be performed without removing the ventilation unit 7. Of course, since the exhaust by the fan 12 can be felt by holding a hand or the like, not only visual inspection but also inspection by bodily sensation is possible.
Although the detailed structure of the motor 13 is not shown in FIG. 3B, an arrow D extending from the opening 10c to the opening 10b is provided between the inner wall surface of the fixture 10 and the motor 13. A sufficiently large gap is formed so as not to obstruct the air flow as shown.

  As shown in FIG. 4A, when the ventilation unit 7 having the above structure is inserted into the ventilation hole 6a and connected to the solar cell panels 8a and 8b (see FIG. 1C) via the wiring 9, The fan 12 rotates by being driven by the motor 13 supplied with power from the solar cell panel 8a. As a result, as indicated by the arrow D, the air inside the osteotomy chamber 1 is discharged to the outside through the ventilation hole 6a. Along with this, a flow of air flowing from the outside into the osteoid chamber 1 through the ventilation holes 6b and 6c is generated (arrow E in FIG. 4B). Thereby, the inside of the ossuary chamber 1 is forcibly ventilated.

As described above, when the power supply from the solar cell panel 8 a to the motor 13 is sufficient, the solar cell panel 8 b charges the built-in storage battery 19. If the power generation by the solar cell panel 8a is not sufficient due to cloudy weather, rainy weather, or nighttime, and the power supplied to the motor 13 is insufficient, the storage battery 19 is supplied to the motor 13 according to the command of the control unit 18 as described above. In contrast, power is supplied. Thereby, the inside of the ossuary chamber 1 is continuously ventilated.
Moreover, in the ossuary chamber ventilation apparatus of a present Example, since the fan 12 and the motor 13 are integrated as the ventilation unit 7, attachment with respect to the ventilation hole 6a is easy. In particular, when the ventilation unit 7 is inserted into the ventilation hole 6a from the outside, the locking portion 10a of the fixture 10 is locked to the edge of the ventilation hole 6a. There is no risk of falling. Note that the opening 10c of the fixture 10 is formed to be smaller than the motor 13 so that the motor 13 does not go out of the opening 10c even when the ventilation unit 7 is tilted.
Further, in the state where the ventilation unit 7 is inserted in the ventilation hole 6a, the rain protection cover 11a prevents the rainwater from flowing into the ventilation hole 6a, and the insect protection cover 11b prevents the insects and the like from entering the ventilation hole 6a. Demonstrate the effect of blocking. Therefore, there is no possibility that the fan 12 or the motor 13 may get short-circuited due to water or insects may be involved, causing the fan 12 to fail.

  As described above, in the osteoid ventilator of the present embodiment, the ventilation unit 7 can be inserted from the outside into the ventilation hole 6a and can be easily arranged at a predetermined location. Moreover, since the wiring 9 is detachably connected to the solar cell panels 8a and 8b and the ventilation unit 7 via connectors, the solar cell panels 8a and 8b and the ventilation unit 7 can be easily detached. Further, a spare length is formed at the connection portion between the wiring 9 and the motor 13, so that the ventilation unit 7 inserted and arranged from the outside to the ventilation hole 6a can be easily moved from the ventilation hole 6a to the outside again. Since it can be pulled out, the ventilation unit 7 can be installed, removed, and inspected without opening the ossuary chamber 1. Therefore, workability is good. This reduces costs associated with installation, removal and maintenance. Moreover, since nothing is installed inside the ossuary chamber 1 except that the wiring 9 is installed along the inner wall surface of the ossuary chamber 1, the inside of the ossuary chamber 1 can be widely used. Furthermore, it is possible to forcibly ventilate the interior of the ossuary 1 regardless of the weather and time, and to keep the humidity always low. Thereby, generation | occurrence | production of mold | fungi and a pest can be prevented. In addition, since the structure of the device is simple, it is difficult to break down and the manufacturing cost is reduced.

  In addition, the osteotomy room ventilation apparatus of this invention is not limited to the case shown in a present Example. For example, the number and installation locations of the solar cell panels 8a and 8b are not limited to those shown in FIGS. 1C and 4B, and can be changed as appropriate. Further, instead of installing the wiring 9 along the inner wall surface of the osteoid chamber 1, the wiring 9 may be installed so as to be drawn out from the ventilation hole 6a. In this case, when installing the ossuary chamber ventilation device, it is not necessary to open the ossuary chamber 1 at all, and workability and checkability when performing installation, removal or maintenance are greatly improved. Therefore, the life of the ventilation unit 7 can be extended. Further, the locking portion 10a may have a shape other than the flange shape. In addition, the shape and material of the rain repellent cover 11a and the insect repellent cover 11b are not limited to those shown in the present embodiment, and can be changed as appropriate. For example, the insect repellent cover 11b may be a mesh member. Moreover, the ventilation unit 7 can also be installed in the ventilation hole 6b or the ventilation hole 6c instead of the ventilation hole 6a.

Next, the ossuary chamber ventilation apparatus of Example 2 is demonstrated using FIG.5 and FIG.6.
FIGS. 5A to 5C are a rear view, a side view, and a plan view, respectively, of a Japanese tomb in which Example 2 of the ossuary chamber ventilation apparatus according to the embodiment of the present invention is installed. 6 (a) and 6 (b) are a side view of the ossuary chamber ventilation apparatus of Example 2 and an enlarged view taken along the line XX of FIG. 5 (c), respectively. FIG. It is a modification of (b). 6A and 6B correspond to FIGS. 3B and 4A of the first embodiment, respectively.

  In the first embodiment, the solar cell panels 8a and 8b are installed on the upper surface of the cap stone 4, whereas in the present embodiment, the solar cell panels 8a and 8b are disposed on the upper surface of the cap stone 4 as shown in FIGS. A recess (not shown) is formed in the upper inclined portion 14a of the upper bed stone 14, and the solar cell panels 8a and 8b are installed in the recess with the upper surface exposed. A heat-resistant member (not shown) is installed between the upper stone 14 and the solar cell panels 8a and 8b. Thus, by providing a recess in the stone material arranged in the upper part of the ossuary chamber 1 and installing the solar cell panels 8a and 8b therein, the solar cell panels 8a and 8b are hardly exposed to the human eye. . Therefore, there is no risk of damaging the surrounding aesthetics.

  Further, as shown in FIG. 6 (a), the ossuary chamber ventilation apparatus of the present embodiment is the same as the ossuary room ventilation apparatus of the first embodiment, in which a mounting tool 15 made of a thin plate spring material is attached to the side surface of the motor 13. The inner surface of the tool 10 is installed so that it can be pressed, and a filter 11c made of non-woven fabric is attached to the rear part of the motor 13 so as to cover the entire opening 10d of the fixture 10. With such a structure, the fan 12 and the motor 13 can be attached to and detached from the fixture 10 in the osteoid ventilator of the present embodiment. In this embodiment, unlike the case of the first embodiment, the opening 10 d of the fixture 10 is formed larger than the motor 13.

  In the osteotomy ventilator of the present embodiment, since the mounting tool 15 is elastically deformed, the fan 12 and the motor 13 can be easily attached to and detached from the mounting tool 10. Further, when the mounting tool 15 that is elastically deformed presses the inner surface of the mounting tool 10, the fan 12 and the motor 13 are fixed to the mounting tool 10. Further, the filter 11c prevents insects and dust from entering the ventilation unit 7 from the inside of the ossuary chamber 1. Furthermore, as shown in FIG. 6B, when the ventilation unit 7 is mounted in the ventilation hole 6a, the entire opening on the ostium room side of the ventilation hole 6a is covered with the filter 11c. Thereby, the penetration | invasion to the ventilation unit 7 of garbage, an insect, etc. which exist in the inside of the ossuary chamber 1 is blocked | prevented. In addition, leakage of odors from the ossuary 1 to the outside is also prevented.

  As described above, according to the osteogenic ventilator of the present embodiment, the ventilation unit 7 is installed in the ventilation hole 6a by inserting the fan 12 and the motor 13 into the fixture 10 from the opening 10d side. Can be installed. Further, it is possible to prevent a failure due to the invasion of dust, insects, etc. existing in the ossuary chamber 1. Furthermore, even when a bad odor is generated inside the ossuary chamber 1, the state of the air discharged from the ventilation hole 6a can be kept clean. When the fan 12 and the motor 13 are inserted into the fixture 10, they are housed in a removable sleeve (not shown) having an opening having the same shape as the opening 10d of the fixture 10. Then, the sleeve may be attached to the fixture 10. By providing such a sleeve, the sleeve length can be adjusted in accordance with the thickness of the wall surface of the ossuary chamber 1, and the fan 12 and the motor 13 can be easily mounted even if the fixture 10 is an existing one. . Further, since the fan 12 and the motor 13 do not necessarily have to be inserted into the fixture 10, the sleeve length can be set according to the size of the fan 12 and the motor 13. Therefore, the handleability can also be improved.

The solar cell panels 8a and 8b are provided with recesses in the stone material arranged in the upper part of the ossuary chamber 1, and the entire structure of the solar cell panels 8a and 8b and the opening 10d of the fixture 10 are covered. Thus, the structure in which the filter 11c is installed is not limited to the present embodiment, and can be similarly adopted in the first embodiment. Furthermore, the formation part of the recessed part for installing solar cell panel 8a, 8b is not restricted to the upper surface inclination part 14a of the upper base stone 14, It can change suitably.
6 (a) and 6 (b), the fan 12 and the motor 13 are inserted and arranged inside the fixture 10, but the ossuary chamber ventilation apparatus of the present embodiment is limited to such a structure. It is not a thing. That is, the length of the cylindrical part of the fixture 10 may be shorter than the length of the ventilation hole 6a, and the fixture 10, the fan 12, and the motor 13 may be separately installed with respect to the ventilation hole 6a. . In this case, the mounting tool 15 acts to press the inner surface of the ventilation hole 6a and fix the fan 12 and the motor 13 to the ventilation hole 6a. The mounting tool 15 is not necessarily a thin plate-like spring material, and may be an elastic member such as rubber or sponge, for example.
Further, instead of inserting and arranging the fan 12 and the motor 13 in the ventilation hole 6a, the fan 12 and the motor 13 are housed in the substantially cylindrical mounting tool 16 as shown in FIG. The fixture 16 may be fixed to the inner wall surface of the ossuary chamber 1 by using a fixture 17 having a substantially L shape in cross section. Note that the opening 16b of the fixture 16 is formed smaller than the motor 13 so that the motor 13 does not go outside when the ventilation unit 7 is tilted. Further, a filter 11 d made of a nonwoven fabric is attached behind the motor 13 so as to cover the entire opening 16 b of the fixture 16. The inner wall surface on the opening 16a side of the fixture 16 is formed so as to become gradually narrower toward the opening 16a so that the wind generated by the fan 12 is concentrated and blown to the fixture 10. It has been devised. According to such a structure, even when the existing ventilation hole 6a is small, the fan 12 and the motor 13 having a desired size can be installed without modification. Therefore, the fan 12 and the motor 13 having desired performance can be used without being influenced by the size of the ventilation hole 6a. In addition, the fixing method of the fan 12 and the motor 13 with respect to the inner wall surface of the ossuary chamber 1 is not limited to the case shown in FIG.6 (c), It can change suitably. Moreover, it can also be set as the structure where only the motor 13 was installed in the inner wall surface of the ossuary chamber 1.
In addition, the positional relationship between the fan 12 and the motor 13 is not limited to the case shown in the first embodiment or the second embodiment. For example, in Example 1 or Example 2, the fan 12 may be installed on the side close to the inside of the osteoid chamber 1. In this case, since the motor 13 is installed on the side close to the opening 10b of the fixture 10, when the wiring 9 connected to the motor 13 is pulled out from the opening 10b of the fixture 10, the fan 13 There is an advantage that 12 does not get in the way.

Next, the ossuary chamber ventilation apparatus of Example 3 will be described with reference to FIGS. 7 to 11 (particularly, corresponding to claims 1, 3 and 6).
Fig. 7 (a) is a plan view of a Japanese grave where Example 3 of the ossuary chamber ventilation apparatus according to the embodiment of the present invention is installed, and Fig. 7 (b) is related to the ossuary chamber ventilation apparatus of this example. It is a side view of a dehumidification unit.

FIG. 10 is a partially enlarged view of the cross section taken along the line XX in FIG. 7A, and FIG. 11 is a view showing a modification of the dehumidifying unit according to the ossuary ventilator of the third embodiment. The components shown in FIGS. 1 to 6 are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in FIG. 7 (a), the osteoid ventilator of the present embodiment is characterized in that in addition to the ventilation unit 7 of the first embodiment, a dehumidifying unit 21 inserted into the ventilation hole 6b is provided. . As shown in FIG. 7 (b), the dehumidifying unit 21 includes a fixture 10 provided with vents 10e to 10g on the side surface near the opening 10c and a heat radiating plate 23 having a plurality of comb-like fins. The Peltier element 22 mounted on the surface 22b is fixed to the side surface of the heat dissipating portion 23 at one end, and the rectangular shape is extended along the axial direction of the fixture 10 so that the other end reaches the opening 10b. It consists of a support plate 24 and a fixing plate 25 that fixes the heat radiating plate 23 to the inner wall surface of the fixture 10. In addition, the Peltier element 22 and the heat sink 23 are installed between the opening part 10c and the vent holes 10e-10g. Moreover, the heat sink 22 is installed so that the fins are substantially horizontal. As a result, the air that has flowed through the fixture 10 and reached the heat radiating plate 22 is rectified by the fins, so that it easily flows to the vents 10 e and 10 g provided on the left and right sides of the heat radiating plate 22.

The Peltier element 22 is disposed so as to be perpendicular to the axial direction of the fixture 10 and the heat absorbing surface 22a is exposed from the opening 10c, and is connected to the solar cell panels 8a and 8b via the wiring 9. “The heat absorbing surface 22a of the Peltier element 22 is exposed from the opening 10c of the fixture 10” means “when the heat absorbing surface 22 of the Peltier element 22 is viewed from the opening 10c side. It means “visible”. Further, the Peltier element 22 and the wiring 9 are detachably connected by a connector (not shown), and the connection portion is waterproofed. A spare length is formed so that the dehumidifying unit 21 can be easily pulled out from the inside of the ventilation hole 6b to the outside during inspection or replacement.
A through hole 10h is provided in a radial direction in a part of the engaging portion 10a in the vicinity of the drainage port 26b of the water conduit 26 formed by a gap between the support plate 24 and the inner wall surface of the fixture 10. And the inner wall surface of the fixture 10 near the other opening end of the water conduit 26 is reduced in diameter toward the opening 10c to form a water receiving port 26a.

  As shown in FIGS. 8A to 8C, the support plate 24 is installed below the dehumidifying unit 21 when viewed from the front, and the through hole 10 h extends from the inside of the fixture 10 downward to the locking portion 10 a. It has been drilled. Moreover, the heat sink 23 is installed inside the fixture 10 so that the plurality of fins 23a are substantially horizontal. And the vents 10e-10g are provided in the upper part of the side surface of the fixture 10, and right and left, respectively. Furthermore, the upper part of the side surface of the heat sink 23 and the left and right gaps with respect to the inner wall surface of the fixture 10 are shielded by the fixing plate 25, and the support plate 24 whose one end is fixed to the lower side surface of the heat sink 23 and the inner wall surface of the fixture 10. As described above, the gap between and forms the water conduit 26. The support plate 24 and the fixing plate 25 are made of a heat insulating member made of synthetic resin having wood or heat resistance, and have an action of blocking heat transfer from the heat radiating plate 23 side to the heat absorbing surface 22a side of the Peltier element 22. is doing.

  As shown in FIG. 9, while the solar cell panels 8a and 8b are exposed to sunlight, the solar cell panel 8a supplies power to the motor 13 and the Peltier element 22 as indicated by an arrow A, and as indicated by an arrow B. The solar battery panel 8b charges the storage battery 19. When the sensor 20 detects that the output voltage of the solar battery panel 8a is lower than the set value, the sensor 20 sends a detection signal a to the control unit 18, and the control unit 18 sends a command signal b to the storage battery 19. Thereby, as shown by the arrow C, the storage battery 19 supplies electric power to the motor 13 and the Peltier element 22.

Next, the operation of the dehumidifying unit 21 will be described with reference to FIG.
First, the dehumidifying unit 21 is inserted into the ventilation hole 6b so that the opening 10c of the fixture 10 is located on the bone delivery chamber 1 side. Next, when electric power is supplied to the Peltier element 22 from the solar cell panels 8a and 8b, heat is transferred from the heat absorption surface 22a to the heat dissipation surface 22b, the heat absorption surface 22a is cooled, and the heat transferred to the heat dissipation surface 22b is dissipated. It is discharged from the plate 23 into the air in the dehumidifying unit 21. In the ossuary chamber ventilator of the present embodiment, by operating the ventilation unit 7 inserted in the ventilation hole 6a, the air in the exterior of the ossuary chamber 1 is opened at the opening of the fixture 10 as indicated by the arrow E. After flowing into the dehumidifying unit 21 from 10b and taking heat away from the heat sink 23, it flows out from the vents 10e to 10g to the bone chamber 1. Due to this air flow, heat dissipation from the heat radiating plate 23 is promoted, and cooling of the heat absorbing surface 22a of the Peltier element 22 proceeds. As a result, moisture contained in the air in contact with the endothermic surface 22a is condensed and becomes condensed water. The condensed water drops by its own weight along the heat absorbing surface 22a and flows into the water conduit 26 through the water receiving port 26a as indicated by an arrow F. Then, as shown by an arrow G, the condensed water flowing in the water conduit 26 flows out of the ventilation hole 6b through the gap between the drain outlet 26b and the insect repellent cover 11b, and further flows down through the through hole 10h.

  As described above, in the ossuary chamber ventilation apparatus of the present embodiment, it is easy to attach and remove the dehumidifying unit 21 to the ventilation hole 6b. Accordingly, the cost associated with the installation, removal and maintenance of the dehumidifying unit 21 can be reduced. Moreover, since the dehumidifying unit 21 is configured to be installed in the ventilation hole 6b, the inside of the osteoid chamber 1 can be widely used. Furthermore, in addition to the ventilation by the ventilation unit 7, the dehumidification unit 21 forcibly reduces the humidity in the ossuary chamber 1, so that generation of mold and pests can be prevented more reliably than in the first embodiment. is there. In addition, since the dehumidifying unit 21 has a simple structure, it is unlikely to fail. Moreover, it can be manufactured at low cost.

In addition, the direction of the air which flows through the inside of the ventilation unit 7 or the dehumidification unit 21 is not limited to the case shown in a present Example. That is, even if the air flow is in the direction opposite to the arrow D and the arrow E in FIG. 7A, the action and effect of the ventilation unit 7 and the dehumidifying unit 21 are exhibited as in the case of the present embodiment. Moreover, the dehumidification unit 21 can also be installed not in the ventilation hole 6b but in the ventilation hole 6c. Furthermore, instead of forming the water conduit 26 with the support plate 24 and the inner wall surface of the fixture 10, a pipe having a funnel-shaped water inlet 26 a may be used as the water conduit 26. In this case, a vent can be provided also in the lower part of the side surface of the fixture 10. And when the clearance gap between the support plate 24 and the side surface of the fixture 10 is small, and there is little heat amount which moves to the heat absorption surface 22a side of the Peltier element 22 via the water conduit 26 side from the heat sink 23 side, a support plate A member having high thermal conductivity such as copper can be used for 24. In this case, since the support plate 24 also functions as a heat sink, the dehumidifying effect by the Peltier element 22 is further enhanced.
Further, as shown in FIG. 11, a motor 13 that operates by receiving power supply from the solar cell panels 8 a and 8 b via the wiring 9 and a fan 12 driven by the motor 13 are provided inside the dehumidifying unit 21. It may be an installed structure. According to such a structure, by rotating the fan 12, a stronger air flow (arrow E) is generated inside the dehumidifying unit 21 than in the present embodiment. Thereby, since the heat radiation from the heat sink 23 is further promoted than in the present embodiment, the dehumidifying effect by the dehumidifying unit 21 can be further enhanced. Further, since the ventilation unit 7 can be omitted, the manufacturing cost can be reduced.

The osteotomy ventilator of Example 4 will be described with reference to FIG. 12 (particularly, corresponding to claim 2).
FIGS. 12A and 12B are a side view and a plan view, respectively, of a dehumidifying unit according to Example 4 of the osteoid ventilator according to the embodiment of the present invention. In addition, about the component shown in FIG. 1 thru | or FIG. 11, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
As shown in FIGS. 12 (a) and 12 (b), the osteoid ventilator of the present embodiment is a Peltier element 22 and a heat radiating plate 23 arranged perpendicular to the axial direction of the fixture 10 in the third embodiment. Instead of the heat sink 28 in the shape of the letter “he” in side view, and the Peltier element 27 mounted on the heat sink 27 b. The heat radiating plate 28 is installed on the support plate 24 so as to expand from the opening 10b toward the opening 10c. The left and right gaps on the side surface of the radiator plate 28 with respect to the inner wall surface of the fixture 10 are shielded by the fixing plate 25, and the upper gap on the side surface of the radiator plate 28 with respect to the inner wall surface of the fixture 10 is covered by the upper part of the radiator plate 28. It is shielded by a substantially triangular heat insulating plate 29 and a fixed plate 25 provided. Moreover, the heat sink 28 is installed inside the fixture 10 so that the fins 28a are substantially horizontal.

  In the ossuary chamber ventilator having such a structure, the air outside the ossuary chamber 1 flowing into the dehumidifying unit 21 from the opening 10b of the fixture 10 reaches the heat radiating plate 28 and then rectifies the plurality of fins 28a. The action moves to the vents 10e and 10g along the heat radiating plate 28, so that heat radiation from the heat radiating plate 28 is further promoted than in the case of the third embodiment. Therefore, the dehumidifying effect by the dehumidifying unit 21 can be enhanced as compared with the case of the third embodiment.

  In the case of the present embodiment, as in the modification of the third embodiment (see FIG. 11), the dehumidifying unit 21 is operated by receiving power supplied from the solar cell panels 8a and 8b via the wiring 9. And a fan 12 driven by the motor 13 can be provided.

  The invention described in claims 1 to 6 of the present invention can be applied regardless of whether it is a Japanese grave or a Western grave, and whether the ossuary is of the above-ground type or underground type. It is.
