Description

  The present invention relates to a partition device that partitions rooms and the like.

  Conventionally, walls, partitions, folding screens, partitions, and the like are known as partitions between rooms, and curtains, blinds, fences, and the like are sometimes used for simple partitioning.

  For example, in the guest room structure of an inn described in Patent Document 1 below, a partition that can be selectively switched from either one of two rooms to a state where the other can be seen through and a state where the other cannot be seen through is provided. ing. As this partition, Patent Literature 1 exemplifies a water tank device using a thin water tank that can be selectively switched between a transparent state and an opaque state by the generation or non-occurrence of bubbles.

  Specifically, the water tank apparatus includes a thin liquid container, an air pump, and an air diffusing pipe, and generates bubbles from the air diffusing pipe by driving the air pump. In this water tank device, it becomes opaque as a large amount of foam is generated, and it becomes impossible to see through the other from either one of the two chambers, and when the generation of foam is stopped, it is switched to a transparent state, The two rooms become transparent, and the feeling of narrowness is eliminated.

  However, in the above water tank apparatus, the size of the air bubbles to be generated is relatively large, and it is difficult to generate fine bubbles in a liquid such as water so as to enable white turbidity. For this reason, even if a large amount of bubbles are generated, it is pointed out that the shielding effect as a partition is not so high between the two rooms because it is difficult to see from one to the other.

  This invention is made | formed in view of the above situations, and makes it a subject to provide the partition apparatus which can implement | achieve an effective shielding effect, utilizing an air bubble.

 In order to solve the above-mentioned problem, the partition device of the present invention is a water tank provided with two transparent plates opposed to each other with a space in the front and rear, and after taking out the water stored in this water tank to the outside of the water tank A partition device having a circulation channel for returning to the water tank, which is equipped with a pump, takes air into the water taken out from the water tank, and generates fine air bubbles having an average particle diameter in the range of 0.1 to 50 μm. The bubble generating means is provided in the middle of the circulating water channel.

  In this partition device, it is preferable to include water supply means for pouring water that does not contain fine bubbles into the water tank.

  Further, in this partition device, the fine bubble generating means relates to the pump and the circulating water channel, the dissolving tank disposed downstream of the pump, and the circulating water channel relating to the decompressing means disposed downstream of the dissolving tank. In a dissolution tank, air is dissolved in a pressurized state in water pumped from a pump, air-dissolved water is generated, pressure is reduced in a decompression means, and air dissolved in the air-dissolved water is precipitated, It is more preferable to generate fine bubbles.

  Furthermore, in this partition device, it is more preferable that one end of the intake pipe is connected to the circulation water channel upstream of the pump, and the other end of the intake pipe is opened.

  According to the partition device of the present invention, since the fine bubbles of air are generated in the water by the fine bubble generating means, the water in the water tank becomes cloudy and opaque when the fine bubbles are generated. On the other hand, when the operation of the fine bubble generating means is stopped, the fine bubbles gradually disappear and can be returned to the original transparent water. Therefore, the partition device of the present invention has a high shielding effect due to white turbidity of water when fine bubbles are generated, and can be shielded from light, so that it is effective as a partition device. Further, switching between transparent and opaque can be easily performed by operating / stopping the fine bubble generating means.

It is the perspective view which showed roughly one Embodiment of the partition apparatus of this invention. It is the perspective view which showed the state when operating the partition apparatus shown in FIG. 1, and partitioning between rooms.

  As described above, FIG. 1 is a perspective view schematically showing an embodiment of the partition device of the present invention. FIG. 2 is a perspective view showing a state when the partition device shown in FIG. 1 is operated to partition rooms and the like.

  The partition device 1 has a water tank 2 that has a size capable of partitioning a room or the like. The water tank 2 has a substantially rectangular parallelepiped shape and is thin with a thickness d smaller than the lateral width w and the height h. In the water tank 2, the front plate 3 and the back plate 4 disposed at the front and back with an interval corresponding to the thickness d are both flat, and a transparent plate 5 that can be passed through is adopted. In addition to being colorless, the transparent plate 5 can also be colored to such an extent that the other side can be seen from the near side of the water tank 2. Examples of the material of the transparent plate 5 include glass and resin.

  The left and right side plates 6, 7, the top plate 8 and the bottom plate 9 that form the water tank 2 are also flat. However, the side plates 6, 7, the top plate 8 and the bottom plate 9 do not necessarily need to be transparent, and can be formed from a non-translucent material such as metal or resin.

  Such a water tank 2 has water tightness so that the water 10 poured therein can be stably stored without leaking water. A water supply pipe 11 extending from a water source such as a water supply is connected to an upper end portion of the right side plate 7 of the water tank 2 through a water injection valve 12. The water supply pipe 11 and the water injection valve 12 form water supply means 13 in the partition device 1. The water supply pipe 11 is for pouring water 10 such as clean water not containing fine bubbles into the water tank 2, and water injection and its stop are controlled by a water injection valve 12. By opening the water injection valve 12, the water 10 is injected into the water tank 2, and when it is closed, the water injection is stopped. As a method for opening and closing the water injection valve 12, a manual type or an electric type can be selected. Due to the arrangement of the water supply means 13, water injection into the water tank 2 is easy in the partition device 1.

  In the water tank 2, a drain port 14 is formed at a corner portion at the lower end of the front plate 3, and a drain drain 15 is provided at the drain port 14. The drainage drain 15 is connected to and communicated with the drainage pipe 17 via the drainage valve 16. When maintenance inspection of the water tank 2 or the like or replacement of the water 10 is necessary, the drain valve 16 is opened, and the water 10 can be drained to the outside of the water tank 2, so that the water draining operation is easily realized. The drain valve 16 can be opened and closed in accordance with the water injection valve 12 opening and closing method.

  Furthermore, in the water tank 2, the suction port 18 and the discharge port 19 are provided in the bottom part. The suction ports 18 are formed at the lower end of the right side plate 7, and three discharge ports 19 are formed at equal intervals on the bottom plate 9.

  Further, the partition device 1 has a circulation water channel 20 from the suction port 18 to the discharge port 19. The circulation water channel 20 branches into three on the discharge port 19 side, and the branch water channels 20 a, 20 b, and 20 c are connected to one corresponding discharge port 19.

  In such a circulating water channel 20, the suction port 18 side is set as the upstream side, the discharge port 19 side is set as the downstream side, and the pump 21, the dissolution tank 22, and the decompression means 23 are located in the middle of the circulating water channel 20 from the upstream side to the downstream side. Are provided sequentially. That is, the dissolution tank 22 is disposed downstream of the pump 21 with respect to the circulation water channel 20, and the decompression unit 23 is disposed downstream of the dissolution tank 22 with respect to the circulation water channel 20.

  In addition, one end of an intake pipe 24 is connected to the circulation water channel 20 on the upstream side of the pump 21. The other end of the intake pipe 24 is open to an atmosphere such as a room. A check valve 25 is provided in the middle of the intake pipe 24 to allow air to be sucked from the atmosphere and to prevent leakage of the water 10 from the circulation water channel 20. In the partition device 1, the fine bubble generating means 26 is formed by the pump 21, the dissolution tank 22, the decompression means 23, and the intake pipe 24.

  In the fine bubble generating means 26, the water 10 stored in the water tank 2 is taken out to the circulation water channel 20 through the suction port 18 by the operation of the pump 21. At this time, a negative pressure is generated on the upstream side of the pump 21 in the circulating water channel 20, and air is sucked into the intake pipe 24 by the ejector effect or the like and mixed into the water 10 flowing through the circulating water channel 20. The mixed air and water 10 become a gas-liquid mixed fluid and are pumped into the dissolution tank 22. The pressure inside the dissolution tank 22 is increasing, and as a result, the air in the gas-liquid mixed fluid is dissolved in the water 10 by the pressure mixing action inside the dissolution tank 22 to generate air-dissolved water. The generated air-dissolved water flows downstream through the circulation channel 20 and is decompressed when passing through the decompression means 23. For this reason, cavitation etc. arise and the air melt | dissolved in the water 10 precipitates in a supersaturated state. Air bubbles precipitated in the water 10 are fine ones having an average particle diameter in the range of 0.1 to 50 μm. The water 10 containing such fine bubbles is discharged into the water tank 2 from the discharge ports 19 through the branch water channels 20a, 20b, and 20c as shown in FIG. The fine bubble generating means 26 effectively realizes the generation of fine bubbles as described above.

  While normal bubbles such as those supplied from the air diffuser described in Patent Document 1 only rise quickly in the water, the fine bubbles as described above flow on the water flow. Can be diffused throughout the aquarium 2. Then, due to the floating and accumulation of fine bubbles in the water 10, the water 10 gradually becomes cloudy and becomes opaque. In this state, it is impossible to see the other side from the front side of the water tank 2, and the rooms are partitioned by the partition device 1. Moreover, the light-shielding effect is also obtained.

  On the other hand, when the operation of the pump 21 is stopped, the supply of fine bubbles is stopped, so that the fine bubbles gradually disappear and return to the original transparent water. In this state, the other side can be seen from the near side of the water tank 2.

  Thus, in the partition device 1, switching between transparent and opaque is possible by operating / stopping the fine bubble generating means 26, and switching is simple. The partition device 1 can realize an effective shielding effect while using air bubbles. Even if the thickness d of the water tank 2 is thin, a sufficient shielding effect and further a shielding effect can be obtained. Light control is also possible by controlling the amount of microbubbles generated. In addition, since the partition device 1 can be thin as described above, the partition device 1 can be reduced in weight, and burdens such as transportation to the construction site, loading, and installation can be reduced. Furthermore, the water stored in the water tank 2 can be used for many times of transparent / opaque switching, and the running cost is reduced, which is economical, and the environmental load can be kept low.

  Moreover, in the partition device 1, since the fine bubbles in the water 10 are longer than normal bubbles until they disappear, even if the operation of the fine bubble generating means 26 is stopped, it is not immediately transparent, It can be kept cloudy for a certain amount of time. For this reason, it is possible to shorten the operation time of the fine bubble generating means 26, and the partition device 1 also has energy saving.

  In addition, since the partition device 1 can enjoy the complicated movement of fine bubbles floating in the water 10 with the eyes, it is excellent in design and entertainment. For example, when the shape of the aquarium 2 is changed to the substantially rectangular parallelepiped shape shown in FIGS. 1 and 2 and curved, the movement of the fine bubbles becomes even more complicated and the entertainment is improved. be able to. Further, by adding a water-soluble dye or the like to the water 10, it can be easily colored, and it is possible to express unique design properties.

  In addition, the partition apparatus of this invention is not limited to the above embodiment. Various modes are possible for details such as the shape and size of the water tank, the configuration and structure of the fine bubble generating means, and can be adopted as appropriate. In the partition device 1 shown in FIG. 1 and FIG. 2, the fine bubble generating means 26 provided with the dissolution tank 22 is adopted, but various kinds such as a venturi system can be adopted as the fine bubble generating means. Is possible.
