Description

The present invention relates to a ventilation system for a soundproof room such as a music rental studio.

For example, in Patent Document 1, a gap is left between the ceiling plasterboard, which is the lower-floor ceiling material, and a sound-absorbing material, glass wool, is provided on the lower surface of the floor plywood, which is the upper-floor floor material except the floor joists, using a fastener. There is disclosed a soundproofed wooden house that firmly fixes the wooden house.

In the case of a wooden house as disclosed in Patent Document 1, it is difficult to keep the soundproof construction of the room on the second floor airtight, so sound leakage from the room on the second floor to the room on the lower side cannot be completely eliminated. Also, the users of the room on the second floor are usually limited to families. Therefore, there was almost no possibility that an unspecified number of people would enter the room on the second floor for a long time and cause oxygen deficiency or carbon dioxide poisoning.

However, recently, a soundproof room called a rental music studio has become available which can be easily used by an unspecified number of people. For example, when a vacant room is renovated to create a soundproof room and a large number of users are packed into it, the air conditioner is fully activated to adjust the temperature and humidity. If a piano concert is held here, adults and children will be locked in a soundproof room for a long time, but since the air conditioner has almost no ventilation function, there is concern that it may cause oxygen deficiency and carbon dioxide poisoning. .. On the other hand, oxygen consumption, carbon dioxide emissions, and height are greatly different between adults and children. Therefore, in order for anyone to be able to use the soundproof room with peace of mind, it is essential to construct a ventilation system that takes into consideration such differences between adults and children.

The present invention has been made in view of such circumstances, and an object thereof is to provide a ventilation system for a soundproof room that anyone can use with peace of mind.

The present invention is a ventilation system for a soundproof room, comprising an air supply duct for supplying air sucked from the outside to the room, an exhaust duct for discharging the air in the room to the outside, and an adult housed in the room. And a ventilation device for ventilating the room so that the amount of air supplied from the air supply duct and the amount of air discharged from the exhaust duct can be adjusted according to the number of children and children. To do.

According to the present invention, the air supply duct that supplies the air sucked from the outside to the room, the exhaust duct that discharges the air inside the room to the outside, and the number of adults and children accommodated in the room are configured. Accordingly, since a ventilation device that ventilates the interior of the room so that the amount of air supplied from the air supply duct and the amount of air discharged from the exhaust duct can be adjusted is provided, there is a risk of causing oxygen deficiency and carbon dioxide poisoning. Anyone can use it without anxiety.

As in the second aspect of the present invention, it is preferable that the air supply duct and the exhaust duct are bent at least twice.

According to the invention described in claim 2, since the air supply duct and the exhaust duct are bent at least twice, sufficient ventilation can be performed while preventing sound leakage.

As in the invention according to claim 3, it is preferable that the exhaust duct is capable of discharging the air near the floor in the room to the outside of the room.

According to the invention of claim 3, the exhaust duct can discharge the air near the floor in the room to the outside of the room, so that the safety of children can be ensured.

An electric shutter may be provided because there is concern that outside air may enter when the vehicle is stopped or when wind is strong, but it is not effective during a power failure. Therefore, as in the invention according to claim 4, it is preferable that the exhaust duct be capable of interposing a vortex diode for increasing the line resistance when the air flows backward as compared with the forward flow.

According to the invention as set forth in claim 4, since the exhaust duct can include a vortex diode for increasing the line resistance when the air flows backward as compared to when the air flows forward, outside air enters even when the air is stopped or during a power failure. Can be reliably prevented.

According to a fifth aspect of the present invention, the soundproof room has a solid foundation, a multiwall that is erected on the solid foundation and includes a first soundproof material, and the first multiwall has almost no break. A plurality of ceilings that are continuous and include a second soundproofing material, and a floor material is placed on the solid foundation with the third soundproofing material sandwiched between the solid sounding material and the solid foundation, and the surroundings of the solid foundation are raised. It is preferable that the third soundproofing material is extended and sandwiched in the rising portion so that the periphery of the floor material abuts.

According to the invention of claim 5, the soundproof room has a solid foundation, a multiple wall that is erected on the solid foundation and includes a first soundproof material, and the first multiple wall is substantially seamless. A plurality of ceilings that are continuous and include a second soundproofing material, and a floor material is placed on the solid foundation with the third soundproofing material sandwiched between the solid sounding material and the solid foundation, and the surroundings of the solid foundation are raised. The third soundproofing material is extended and sandwiched in the rising portion so that the periphery of the floor material is in contact with the soundproofing material, so that the sound source can be a heavy object.

As a result of not worrying about sound leakage from this sound source, it is possible to fully play a loud acoustic instrument even at midnight.

Further, since the periphery of the floor material abuts with the third soundproofing material being extended and sandwiched in the rising portion while raising the periphery of the solid foundation, vertical and horizontal shaking during an earthquake is prevented. Can handle both.

According to the present invention, the air supply duct that supplies the air sucked from the outside to the room, the exhaust duct that discharges the air inside the room to the outside, and the number of adults and children accommodated in the room are configured. Accordingly, since the ventilation device for ventilating the room is provided so that the amount of air supplied from the air supply duct and the amount of air discharged from the exhaust duct can be adjusted, anyone can use it with peace of mind.

(Embodiment 1)
FIG. 1 is a perspective view showing an appearance of a soundproof room 1 according to the first embodiment of the present invention, and FIG. 2 is a vertical sectional view showing a detailed structure of the soundproof room 1 according to the first embodiment. However, the left side of the paper of FIG. 1 corresponds to the north side of the soundproof room 1, and the right side corresponds to the west side of the soundproof room 1. As an engineer of a plant maker, the present inventor actually made a soundproof room 1 on the premises of his home by taking advantage of many years of experience in soundproofing measures, and the results obtained there will be described below.

As shown in FIGS. 1 and 2, the soundproof room 1 is a wooden house built independently on the ground. Basically, it is a solid foundation made of concrete and main parts such as wooden columns and beams. However, the sound source 9, which is a heavy object, can be accommodated therein. Examples of the sound source 9 include a grand piano having a weight of more than 500 kg and a large-sized automatic musical instrument. The reason why the building is not entirely made of concrete is that continuous dehumidification with an air conditioner may be necessary to prevent the growth of mold when storing a grand piano or the like. On the other hand, in a wooden house built independently on the ground, there are few such problems, and in the case of a solid concrete foundation that is limited to the underfloor, moisture enters from the ground into the room in the summer. On the other hand, in winter, it is thought to play a role in properly humidifying the room.

Therefore, in the soundproof room 1, a concrete solid foundation 2 cast on the crushed stone 21 and glass wool (corresponding to the first soundproof material) 31 standing upright on the solid foundation 2 are formed into two layers. And a double wall 3 included in a panel board, and suspended from a roof 10 by an anti-vibration hanger 42, which also includes glass wool (corresponding to a second soundproof material) 41 in two layers and is included in the panel board. The double ceiling 3 is provided with a heavy ceiling 4, and the double wall 3 and the double ceiling 4 are substantially continuous, and two layers of rock wool (corresponding to a third soundproof material) 22 are provided on the solid foundation 2. The concrete floor material 5 is placed in a state of being sandwiched between.

Each layer of glass wool has a thickness of about 100 mm, and each layer of rock wool has a thickness of about 25 mm. Further, between the solid foundation 2 and the double wall 3 and between the double wall 3 and the double ceiling 4, a significant gap is eliminated by a packing or a sealer.

The solid foundation 2 is strong against vertical vibration during an earthquake, but does not prevent horizontal vibration. Therefore, the circumference of the floor material 5 is abutted while the circumference of the solid foundation 2 is raised and the rock wool 22 is extended and sandwiched in the rising portion. This makes it possible to deal not only with vertical vibrations during an earthquake but also with horizontal vibrations.

In addition, the symmetry in the plane of the room is reduced and the aspect ratio is greatly changed, so that the sound waves emitted from the sound source 9 are less likely to interfere even when reflected by the wall. In addition to this, for example, a sound insulation sheet (sound insulation material) 32 made of felt is attached to the panel board on the inner side of the north side of the double wall 3, and a sound absorbing panel is used on the panel board on the lower side of the double ceiling 4. Therefore, the wall reflection itself is reduced.

Out of the periphery of the double wall 3, from the lower part on the north side and the west part to the middle part, a slight step is provided in the thickness direction to provide an opening notched to the outside and to include glass wool or the like therein. Double doors 6a and 6b are provided so as to be openable and closable.

A packing is interposed between the double doors 6a and 6b and the opening corresponding to the double doors 6a and 6b in order to prevent the passage of sound waves. The double door 6a is a relatively large door provided for carrying in and out the sound source 9, and a small space is provided between the inner door and the outer door arranged so as to face each other. It is closed during the performance. The double door 6b is a relatively small door provided for the entry and exit of a person, and a space large enough for a person to stay is provided between the inner door and the outer door that are provided at right angles to each other. By adopting the so-called air-lock type, it can be opened and closed even during a performance.

Around the middle of the double wall 3 to the middle portion on the side of the double door 6b, a slight step is provided in the thickness direction to provide an opening notched outward, and there is a triple The glass window 7 is detachably attached. As a result, so-called lighting can be performed. Although not shown, a similar glass window is also provided on the east side.

The air supply duct 82 and the air exhaust duct 84 that penetrate the upper portion of the double door 6b in the periphery of the double wall 3 are provided, and the ventilation device 14 is provided on the double ceiling 4 to provide the air supply duct 82. The exhaust duct 84 and the exhaust duct 84 are bent at least twice and are connected to the ventilation device 14 (see FIG. 3 ). Both the air supply duct 82 and the exhaust duct 84 are made of dew-proof heat insulating material. As a result, sound leakage from the air supply duct 82 and the exhaust duct 84 is reduced, ventilation can be performed in the room, and an increase in humidity in the room can be suppressed.

Here, as a specific method of bending the air supply duct 82 and the exhaust duct 84, it is preferable to bend each of the air supply duct 82 and the exhaust duct 84 by 45 degrees twice or more in the same direction. As a result, the increase in the pipeline resistance due to the air passing through the air supply duct 82 and the exhaust duct 84 is suppressed as much as possible, and the ventilation performance is ensured, while the sound waves are generated inside the air supply duct 82 and the exhaust duct 84. Sound leakage due to slipping through can be reduced.

Small holes are made in the lower wooden part 33 of the double wall 3 at intervals of approximately 0.3 to 1 m, a chemical solution of an insect repellent is injected therein, and each small hole is backfilled with putty. Therefore, so-called termite countermeasures are taken. However, no specific termite countermeasures are applied to the upper wooden part 34 of the double wall 3 and the pillars (not shown) between the two wooden parts 33, 34, but all the wooden parts used in the construction stage are pre-insulated. It is preferable to process.

FIG. 3 is a schematic diagram showing the ventilation system 8 of the soundproof room 1 according to the first embodiment. The solid line in FIG. 3 indicates the duct, and the broken line indicates the electric system. As shown in FIG. 3, the ventilation system 8 uses the air supply fan 14a from the air filter 81 through the air supply duct 82 in accordance with the number of adults M1 and children M2 accommodated in the soundproof room 1 to achieve the soundproof room 1. The amount of air supplied to the inside of the soundproof chamber 1 and the amount of air discharged from the inside of the soundproof chamber 1 to the exhaust port 83 by the exhaust fan 14b through the exhaust duct 84 are adjusted so that the inside of the soundproof chamber 1 is ventilated. The air fan 14a and the exhaust fan 14b are integrated to form the ventilation device 14. The air filter 81 removes particles such as cedar pollen which is a causative substance of pollinosis and PM2.5 which is a causative substance of air pollution. The most basic grade ventilation system 8 will be described below.

Here, “strong” and “weak” selection switches 602 are provided separately from the power switch 601 of the ventilation device 14. The power switch 601 and the selection switch 602 are electrically connected to the air supply fan 14a and the exhaust fan 14b through the control panel 600. Then, the user or owner of the soundproof room 1 (not shown) looks at the selection table as shown in Table 1 and switches the selection switch 602 to either “strong” or “weak”. The children in Table 1 are assumed to be kindergarten children or children in the lower grades of elementary school. At first, since the user is not in the soundproof room 1, the power switch 601 is “off” and the selection switch 602 is “weak”.

Now, when the user of the soundproof room 1 is one teacher (adult) and three children (children), the teacher presses the power switch 601 of the ventilation device 14 to turn it “on”, and see the selection table in Table 1. , The selection switch 602 remains “weak”. Then, the air supply fan 14a and the exhaust fan 14b rotate at a low speed, the outside air is supplied into the soundproof chamber 1 through the air filter 81 and the air supply duct 82, and the air in the soundproof chamber 1 becomes the exhaust duct 84. It is exhausted to the outside of the soundproof room 1 through the exhaust port 83. The air supply amount and the exhaust amount at this time are set to be relatively small (the set value 1 is the maximum value of the ventilation “weak” range in Table 1), but the diagonal line to the lower right of Table 1 In the case of one adult shown in the area (1), it can be understood that up to 6 children shown in the area with diagonal lines rising to the right are OK.

A mother (adult) with two children (children) enters the soundproof room 1 through the outer door 6b2 and the inner door 6b1 of the double door 6b. Then, since there are two adults and five children in the soundproof room 1, the teacher switches the selection switch 602 to “strong”. Then, the air supply fan 14a and the exhaust fan 14b rotate at high speed, the outside air is supplied into the soundproof chamber 1 through the air filter 81 and the air supply duct 82, and the air in the soundproof chamber 1 becomes the exhaust duct 84. It is exhausted to the outside of the soundproof room 1 through the exhaust port 83. The air supply amount and the exhaust amount at this time are set to be relatively large (the set value 2 being the maximum value of the “strong” range in Table 1), but the diagonally sloping line in the lower right of Table 1 In the case of the two adults shown in the area, it can be seen that up to 10 children shown in the area of the double diagonal line rising to the right are OK.

At the end of the first lesson (3 students), the soundproof room 1 will exit through the inner door 6b1 and the outer door 6b2, so there will be 2 adults and 2 children in the soundproof room 1, so the teacher will make a selection switch. 602 is switched to "weak". Then, the air supply fan 14a and the exhaust fan 14b return to the low speed rotation, the outside air is supplied into the soundproof room 1 through the air filter 81 and the air supply duct 82, and the air in the soundproof room 1 becomes the exhaust duct 84. It is exhausted to the outside of the soundproof room 1 through the exhaust port 83. At this time, the air supply amount and the exhaust amount return to the set value 1. When the number of users exceeds the maximum number, the required air amount exceeds the set value 2. Therefore, the teacher limits the number of people who can enter the soundproof room 1. The same applies hereinafter.

At this time, the teacher (adult) switches the selection switch 602 for each break of the lesson, but if it is considered to be troublesome, it may be left as “strong”. However, if the number of users exceeds the maximum number, the number of people entering the soundproof room 1 is limited. When all members leave, the teacher turns off the power switch 601 and sets the selection switch to "weak". Then, both the air supply fan 14a and the exhaust fan 14b stop rotating. Only by such a manual operation, oxygen deficiency and carbon dioxide poisoning due to insufficient ventilation in the soundproof room 1 can be easily and reliably avoided.

After the soundproof room 1 was completed, the sound source 9 was placed almost in the center of the room. The sound source 9 is a combination of sounds of a piano and a drum, and has a range from a high range to a low range. After that, the sound source 9 was turned on and off, and the A characteristic was actually measured using a sound level meter. As a result, even when the noise level of the sound source 9 was 110 db at maximum, the outdoor noise level was about 30 to 40 db, and a sound reduction effect of about 70 to 80 db was actually obtained.

Here, when the sound source 9 is turned on, the maximum measured value at a position 1 m away from the sound source 9 is 110 db, and the measured value at a position 1 m away from the outer wall surface of the double wall 3 at this time is It was about 30 db, and the measured value immediately outside the triple glass window 7 was about 40 db. When the sound source 9 is turned off, the measured value at a position 1 m away from the sound source 9 is about 30 db, the measured value at a position 1 m away from the outer wall surface of the double wall 3 is about 30 db, and the triple glass window 7 The measured value immediately outside was about 30 db. Note that 30 db has the same noise level as the outdoor environmental sound (rain sound, etc.).

Therefore, it was found that in the soundproof room 1, sound leakage was almost completely eliminated. Since a commercially available soundproof room has only a noise reduction effect of about 20 to 40 dB, it can be said that this is an epoch-making result compared to the fact that even if the soundproof room is provided, there is some sound leakage.

As described above, according to the soundproof room 1 of the first embodiment, the solid foundation 2, the double wall 3 standing upright on the solid foundation 2 and containing the glass wool 31, and suspended from the roof 10. A state in which the double wall 3 and the double ceiling 4 are substantially continuously connected and the rock wool 22 is sandwiched on the solid foundation 2 Since the floor material 5 is placed on the inside, the sound source 9 which is a heavy object can be housed inside.

As a result of eliminating the fear of sound leakage from the sound source 9, a loud acoustic instrument can be fully played even at midnight.

(Embodiment 2)
The second embodiment is mainly an upgrade of the ventilation system 8 of the first embodiment. Since the basic structure of the soundproof room 1 is the same as that of the first embodiment, detailed description thereof will be omitted. FIG. 4 is a schematic diagram showing the ventilation system 8a of the soundproof room 1 according to the second embodiment, and FIG. 5 is a conceptual diagram of the vortex diode 83a according to the second embodiment. The solid line in FIG. 4 indicates the duct, and the broken line indicates the electric system.

As shown in FIG. 4, unlike the first embodiment, in the second embodiment, the ventilation device 14 including the air supply fan 14a and the exhaust fan 14b is provided in the lower portion of the double wall 3. Considering that children are shorter than adults, they are more susceptible to oxygen deficiency and carbon dioxide poisoning. As a result, the exhaust duct 84 can discharge the air in the vicinity of the floor 5 in the soundproof room 1 to the outside of the soundproof room 1, and the air supply duct 82 can supply the outside air into the soundproof room 1, which is especially safe for children. Can be secured.

Further, when the ventilation system 8a is stopped or when the wind is strong even when the ventilation system 8a is operating, outside air may enter the soundproof room 1 through the exhaust duct 84. Therefore, conventionally, an electric shutter is provided. However, it is not effective during a power failure. Therefore, in the exhaust duct 84 of the second embodiment, the vortex diode 83a that makes the line resistance larger when the air flows backward than when the air flows forward can be interposed. According to this, outside air can be reliably prevented from entering the soundproof room 1 even when the ventilation system 8a is stopped or a power failure occurs.

The vortex diode 83a is a kind of fluid element, and as its constituent elements, as shown in FIG. 5, a cylindrical main body 831, an inlet nozzle 832 connected to the side surface of the main body 831 in the central axis direction, The main body 831 is provided with an outlet nozzle 833 tangentially connected to the peripheral surface thereof.

In the vortex diode 83a, as shown by A→B in FIG. 5, when air flows in from the inlet nozzle 832 connected to the side surface of the main body 831 in the direction of the central axis, almost no vortex is formed and the small shape resistance Will only occur. On the contrary, as shown by B→A in FIG. 5, when air flows in from the outlet nozzle 833 connected tangentially to the peripheral surface of the cylindrical main body 671, a vortex is surely formed, which causes centrifugal force. The force acts to reduce the central pressure, resulting in a large resistance. As described above, the vortex diode 83a has a smaller resistance when the fluid flows in from one side thereof and a larger resistance when the fluid flows in from the other side thereof, and thus performs a function similar to that of a diode in an electric system.

The ventilation system 8a of the second embodiment will be described below.

Here, as shown in FIG. 4, in the space between the inner door 6b2 and the outer door 6b1 of the double door 6b, for example, sensors 603 to 606, which are photointerrupters composed of a pair of a light emitting unit and a light receiving unit, Two pairs are provided for each of the high and low positions. The higher sensors 603 and 605 are positioned based on the height of the adult M1 and the lower sensors 604 and 606 are positioned based on the height of the kindergarten child and the child M2 of the lower elementary school age, but both are height. It can be adjusted. The ventilation system 8a according to the second embodiment is installed in the soundproof room 1 with the air supply fan 14a from the air filter 81 through the air supply duct 82 according to the number of adults M1 and children M2 housed in the soundproof room 1. The air supply fan is designed to ventilate the soundproof room 1 by adjusting the amount of air supplied and the amount of air discharged from the soundproof room 1 to the vortex diode 83a by the exhaust fan 14b through the exhaust duct 84. 14 a and the exhaust fan 14 b are integrated to form the ventilation device 14. The air filter 81 removes particles such as cedar pollen which is a causative substance of pollinosis and PM2.5 which is a causative substance of air pollution.

Also here, the “strong” and “weak” selection switches 602 are provided separately from the power switch 601 of the ventilation device 14. The power switch 601, the selection switch 602, and the sensors 603 to 606 are electrically connected to the air supply fan 14a and the exhaust fan 14b through the control panel 600.

The control panel 600 here is provided with a memory, a calculation function, a determination function, etc., unlike the first embodiment. Then, the number of adults and children passing through the double door 6b is calculated from the count values of the sensors 603 to 606, and this calculated value corresponds to the set value 1 (the first set value) in the first embodiment. ), the selection switch 602 is automatically switched from “weak” to “strong”. On the other hand, when the calculated value again falls below the set value 1, the selection switch 602 is automatically switched from "strong" to "weak". When the calculated value reaches the set value 2 (corresponding to the second set value) of the first embodiment, the buzzer sounds and the closing of the double door 6b is automatically prohibited by the lock mechanism (not shown). It is supposed to do.

6 and 7 are flowcharts showing an operation example of the ventilation system 8a of the second embodiment. In FIG. 6, when the user or owner turns the power switch 601 “on”, the operation of the control panel 600 causes the number of adults and the number of children stored in the selection switch 602, the sensors 603 to 606, and the memory. Each is reset (step S1). That is, the power switch 601 is “off”, the selection switch 602 is “weak”, and the sensors 603 to 606 are all “off”. The number of adults and the number of children stored in the memory are both zero.

Next, the numbers of adults and children entering and leaving the soundproof room 1 are detected (step S2). In FIG. 7, it is determined whether or not the sensor 603 at the higher position on the outer door 6b2 side of the double door 6b is "ON" (step S201). Then, when the sensor 603 is turned “on”, it is determined whether the sensor 605 at the higher position on the inner door 6b1 side is “on” (step 202). When the sensor 605 is turned "on", one adult is added (step S203). One adult is subtracted in the reverse order (steps S211 to S213).

It is determined whether the sensor 604 at the lower position on the outer door 6b2 side of the double door 6b is "on" (step S221). Then, when the sensor 604 is turned "on", it is determined whether the sensor 606 at the lower position on the inner door 6b1 side is "on" (step 222). When the sensor 606 is turned “on”, one child is added (step S223). One child is subtracted in the reverse order (steps S231 to S233).

Returning to FIG. 6, the required ventilation amount Q is calculated by the following equation (step S3).
Ventilation Q=20*Number of adults N1+10*Number of children N2
Is. The grounds are based on the Ministry of Education, Culture, Sports, Science and Technology "Survey and Research Report on Exhaust Systems of School Facilities" Then, it is determined whether the ventilation amount Q is larger than the set value 1 (step S4). When the ventilation amount Q becomes larger than the set value 1, the selection switch 602 automatically switches from "weak" to "strong" (step S5). Further, it is determined whether the ventilation amount Q is larger than the set value 2 (step S6). When the ventilation amount Q becomes larger than the set value 2, the buzzer sounds and the double door 6b does not close, so that a so-called entry restriction is made (step S7). It is determined whether the user or the owner turns off the power switch 601 to release the restriction (step S8). When the power switch 601 is turned off and the restriction is released, the automatic operation ends at that point. This makes it possible to more reliably avoid oxygen deficiency and carbon dioxide poisoning due to insufficient ventilation.

Although it is not the soundproof room 1, the present inventor has the experience of arranging the photovoltaic power generation panel 11 on the roof 10 in the same wooden house, and in order to improve the power generation efficiency, the photovoltaic power generation panel 11 I thought about washing with water. Specifically, the rainwater from the roof 10 is made available as wash water for the photovoltaic power generation panel 11 through the rainwater tub 12. A schematic diagram showing the electric system and the water system in that case is shown in FIG. In addition, the broken line in FIG. 8 shows an electric system, and the two-dot chain line shows a water system.

As shown in FIG. 8, direct current (DC) generated in the photovoltaic power generation panel 11 is converted into alternating current (AC) by the inverter 501, and the water distribution device 13, the ventilation device 14, and other electric devices (air conditioners) are converted by the switchboard 502. , Lighting, musical instruments, etc.). Here, the surplus power is stored in the storage battery 503 or returned to the system via the watt-hour meter 504 and sold, while the insufficient power is supplied from the storage battery 503 or the watt-hour meter 504 is used. Power will be supplied from the grid via the system.

Rainwater collected from the roof 10 by a gutter (not shown) is temporarily stored in a rain tub 12 provided near the ground GL, and is sprinkled by the sprinkler 13 as washing water for the photovoltaic power generation panel 11 at a predetermined timing. To do so. The predetermined timing may be irregular, such as when the photovoltaic panel 11 is soiled by yellow sand or bird droppings, or may be regular.

In the summer, the watering has a certain effect of keeping the room cold, and in the winter of the watering, having a certain effect of melting the snow. If the amount of sprinkling water cannot be caught up only by storing water in the rain tub 12, tap water or well water can be used. If there is excess water in the rain tub 12, it can also be used for watering the garden. I have to. The solar power generation panel 11 is placed on the roof 10, and can be easily removed when the roof 10 is repaired, and the repair can be easily performed.

In the first and second embodiments, as the soundproof room 1, a rental music studio or the like is illustrated, but a soundproof room and a private diesel generator for the purpose of raising other loud pets such as large parakeets and dogs. It may be a soundproof room or the like having the purpose of incorporating mechanical equipment that emits noise, such as a machine tool.

Further, in the above-described first and second embodiments, the soundproof room 1 is composed of an independent house, but the soundproof room 1 does not necessarily have to be a completely independent house. For example, the soundproof room 1 may be the first floor of the main house. Further, instead of the wooden house, a concrete house or one room of an apartment/apartment may be used. In that case, measures against moisture in summer and measures against dryness in winter are required.

Further, in the above-described first and second embodiments, glass wool is used as the first and second soundproofing materials, and rock wool is used as the third soundproofing material, but any of them may be used, and other equivalent It may be a material having the performance of. However, high specific gravity materials such as lead, which may adversely affect the health and environment of workers, shall not be used at all.

Further, since glass wool, rock wool and the like have excellent heat insulation performance, the room temperature can be maintained almost constant even if the outside air temperature fluctuates to some extent, which is advantageous for storing musical instruments and the like.

However, the ventilator 14 alone may not be sufficient depending on conditions such as when the outside air temperature becomes higher or lower, the amount of heat generated by a musical instrument or lighting, or when a person is in the room. In that case, in that case, an air conditioner (not shown) or the like may be used. However, since the air conditioner has almost no ventilation function, the ventilation systems 8 and 8a of the soundproof room 1 are indispensable.

In addition, although the triple glass window 7 is provided in the first and second embodiments, at least a single-layer glass window 7 may be used. Instead of this glass, transparent acrylic may be adopted. The double wall 3 and the double ceiling 4 may be further multiplexed depending on the soundproof performance, or conversely may be a single-layer wall or ceiling.

Further, in the above-described first embodiment, it is divided into two types of persons, an adult and a child, but may be divided into three or more types including an intermediate between an adult and a child. Further, although the user or the owner is supposed to operate the power switch 601 and the selection switch 602, if a security surveillance camera 607 (see FIG. 4 of the second embodiment) is installed indoors or outdoors, this should be done. The operation may be instructed from outside the room to an adult inside the room.

Also in the second embodiment described above, the number of sensors may be increased and the setting and operation thereof may be complicated, although they may be divided into three or more types including those between adults and children. In that case, the image pattern of the monitoring camera 607 may be analyzed by AI technology such as deep learning. Further, the sensor is not limited to the photo interrupter, and for example, a load cell may be used to judge an adult and a child based on the weight difference. Further, an ultrasonic sensor, a magnetic sensor or the like may be used.

In the first and second embodiments, the ventilation device 14 has the air supply fan 14a and the exhaust fan 14b integrated with each other, but may be provided separately. In that case, for example, the attachment position of the air supply fan 14a may be the double wall 3 or the double ceiling 4, and the attachment position of the exhaust fan 14b may be the lower part of the double wall 3 or the opposite arrangement. .. Further, a plurality of ventilation devices 14 may be provided to perform parallel operation or series operation.

Further, in the above-described Embodiments 1 and 2, the ventilation systems 8 and 8a are incorporated when the soundproof room 1 is newly built, but the ventilation systems 8 and 8a may be retrofitted to an existing soundproof room. Good. Further, it is not necessary to equip the ventilation systems 8 and 8a in a complete manner, and it is also possible to equip a part thereof, or it is possible to equip additional options. For example, like a soundproof room for pets, it may be provided with only one of the air supply fan and the exhaust fan, although it is related to the required soundproof performance. Further, depending on the environment, the air fill of the air supply duct may be omitted. Furthermore, a more safe system can be constructed by providing an extension duct for the exhaust fan and opening it in the area where the child is.
