(Embodiment 1)
The gas purification system in Embodiment 1 of this invention is demonstrated using FIGS. FIG. 1 is a diagram showing a configuration of a gas purification system in the present embodiment.

  As shown in FIG. 1, the gas purification system according to the present embodiment has an air including a clean filter 22 as an impurity recovery unit that recovers impurities contained in the gas by flowing the gas in the space, for example, impurity particles. A cleaner 23, circulators 24A to 24D as gas flow means arranged to be separated from the air cleaner 23 and flowing the gas, and a dust sensor 25 as impurity detection means for detecting impurities in the gas. The air purifier 23 operates in accordance with the amount of impurities detected by the dust sensor 25.

  26 is a control means provided in the air purifier 23, and a control circuit (not shown) for operating the circulators 24A to D when the air blowing operation of the air purifier 23 is stopped or when the capacity is reduced to a low air volume. )have. Further, the circulators 24 </ b> A to 24 </ b> D are operated and controlled while changing the air direction, the air volume, the operation time, and the like, thereby guiding impurities away from the air purifier 23 toward the air purifier 23.

Here, 27 is a room in which the gas purification system in the present embodiment is installed, 28 is furniture, and 29 is an airflow sensor installed in each of the circulators 24A to 24D.
FIG. 2 is an explanatory diagram showing the movement of air in the room. An arrow indicating the main flow, a thin dotted line indicating the vortex flow, and a dotted line indicating the air flow by the circulators 24A to 24D are shown.

  About the gas purification system in this Embodiment comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  In this gas purification system, indoor air is circulated by an air purifier 23, and particles such as impurities and pollen are removed by a purifying filter 22 attached to the air purifier 23 to purify the air. Here, a plurality of circulators 24A, 24B, 24C, and 24D are provided as devices for assisting air circulation. These circulators 24 </ b> A to 24 </ b> D are operated in conjunction with the operation of the air purifier 23 by the control means 26.

  An example of the operation of the control means 26 is shown in FIG. For example, while the air cleaner 23 is operating, the circulators 24A to 24D stop operating (at time T1). And when the air volume by the air cleaner 23 becomes below predetermined air volume, circulators 24A-D start an operation | movement (time T2).

  Even if the operation of the air purifier 23 is turned off, the circulators 24A to 24D continue to operate (at time T3), and when the air purifier 23 restarts the operation, the circulators 24A to 24D stop operating. Yes (at time T4). Then, when the air purifier 23 stops the air blowing operation again, the circulators 24A to 24D start operating (at time T5).

  As described above, the circulators 24 </ b> A to 24 </ b> D are configured to control the operation state without overlapping operations between the strong operations by the operation of the air purifier 23. Moreover, in this Embodiment, operation | movement is controlled by the signal of the dust sensor 25 installed in the inlet 23a vicinity of the air cleaner 23, For example, the detection amount of impurities, such as the impurity which the dust sensor 25 detects, is detected. Control to change the wind direction and the air volume of the circulators 24A to 24D is performed so as to increase.

  The air volume and the wind direction are not fixed, but the signal of the dust sensor 25 is fed back and sequentially changed in the direction in which the detected amount increases. At time T6 in FIG. 3, it is shown that the air volumes of the circulators 24A to 24D are changed. When the output signal of the dust sensor 25 reaches a predetermined amount, the air cleaner 23 starts the air blowing operation again to purify the air.

  The circulator 24 includes an airflow sensor 29 that detects an airflow around the circulator 24. When the airflow generated by the air purifier 23 becomes weak, the circulator 24 collects dust away from the air purifier 23. Start to work. For example, this is the case when the air cleaner 23 is weakly operated or when the blowing direction of the air cleaner 23 is in another direction.

  In addition to the signal from the airflow sensor 29, the operation is started also in the weak operation when the air blowing amount of the air purifier 23 is reduced. As described above, the control unit 26 controls the operation of the circulators 24 </ b> A to 24 </ b> D according to the amount of air blown from the air cleaner 23 and the signal from the airflow sensor 29. At this time, the air purifier 23 and the circulators 24A to 24D can perform the operation status by communicating with a communication unit (not shown), and can also know by the detection of the airflow sensor 29, such as by movement of a human body or furniture. It can also handle the effects of indoor obstacles.

  With such a configuration, impurities floating away from the air purifier 23 can be effectively guided to the vicinity of the air purifier 23 by the circulators 24A to 24D, and the air is efficiently purified. be able to.

  For example, as shown in FIG. 2, an eddy current is generated in the corner of the room as shown by a thin dotted line around the main stream (solid arrow) created by the air purifier 23.

  Impurities riding on the mainstream can be recovered, but impurities circulating along the vortex are not on the mainstream and are difficult to recover.

  Therefore, in the present embodiment, when the air purifier 23 is stopped, that is, when there is no main flow, the circulators 24A to 24D blow the impurities in the main flow direction. Thereafter, when the air purifier 23 starts an operation, impurities floating in the vicinity of the mainstream ride on the mainstream and are collected by the air purifier 23. In this way, by controlling the operation of the circulators 24A to 24D, it is possible to collect impurities that have accumulated in the corners of the room, which has been difficult to collect. Further, even if the circulator 24 is operated during the operation of the air cleaner 23, it is difficult to repel the mainstream flow and to merge the impurities. Efficiency can be improved.

  Furthermore, in the case of a structure such as a hotel 30 as shown in FIG. 4, the structure of each room 31 is almost the same. Therefore, if this gas purification system is installed in each room 31 and the respective gas purification systems are connected via a network, when the air purification of the room 31 is performed, the control information of one room 31 is installed in the management room 32 by the network. Can be collected by the managed device 33.

  And while transferring the information to the gas purification system of the other room 31, impurities can be efficiently recovered by setting the same conditions. In the case of a room having the same structure, the optimum operating condition can be detected in a short time if the operation is started from the same setting condition. As a result, operating power can be saved, and an energy-saving cleaning system can be obtained.

  By connecting the network and managing the operation information, each room 31 can be operated, the overall power consumption per hour can be suppressed, the maximum electric capacity can be afforded, and the contract power consumption Can be set less. It can be easily installed in existing buildings by reducing the network construction by wireless communication.

  In addition, by managing the operation in the network, the gas purification system can be stably operated without buffering each other, and can be operated more safely and efficiently.

  Thus, in the gas purification system in the present embodiment, the circulators 24 </ b> A to 24 </ b> D arranged at positions distant from the air cleaner 23 are efficiently operated so as not to overlap with the operation of the air cleaner 23. Impurities floating away from the air purifier 23 can be guided to the vicinity of the air purifier 23, and energy saving is achieved by limiting the operation time, and a wide range of impurities are efficiently recovered. The air can be purified.

  In addition, the air flow of the air cleaner 23 is not obstructed, and the air flow is less disturbed and can be spent indoors without discomfort. Then, the circulators 24A to 24D can be stopped depending on conditions such as strong, medium, and weak air blowing conditions of the air purifier 23, and impurities can be efficiently recovered without inhibiting the air flow of the air purifier 23. .

  Further, by controlling the circulator 24 with a signal from the airflow sensor 29, it is possible to generate a circulating flow without competing with the airflow of the air purifier 23, and to effectively collect impurities and purify the air. Can do. Furthermore, since the dust around the air cleaner 23 can be increased by feeding back the signal from the dust sensor 25, the impurities can be recovered with a small air volume.

  In the above embodiment, the wall-mounted air purifier 23 provided with the cleaning filter 22 has been described. However, the floor-type air purifier 23, an air conditioner, a filter-equipped fan, a duct air conditioner, a central cleaner, etc. It is clear that even types can be adapted. In addition, when an air conditioner is used, impurities accumulated in a purification filter provided in the indoor unit may be cleaned by a cleaning robot provided in the indoor unit and discharged to the outdoors.

  The circulators 24A, 24C, and 24D are illustrated as floor-standing types, but may be wall-mounted like the circulator 24B.

  Further, in the above embodiment, four circulators 24A, 24C and 24D are used as the gas flow means. However, the present invention is not limited to the number, and one or two circulators are used depending on the structure of the room. If the gas can be sufficiently circulated by the table, only two devices may be used, and conversely, five or more devices may be used.

  As described above, the gas purification system and the gas purification management system according to the present invention can efficiently collect indoor impurities and fine particles such as pollen, and automatically clean the indoor air by operating automatically for 24 hours. Since the fine particles in the space away from the air purifier, which was difficult in the past, can be sucked by being guided by the circulator, the air can be cleaned in a wide space. As a result, since the amount of impurities accumulated on the dresser and the table can be greatly reduced, the cleaning interval can be lengthened, and housework can be reduced. In addition, by adopting a management system, the entire building can be efficiently cleaned where there are a number of rooms having the same shape, such as hotels and hospitals, and can be applied to various gas purification systems.
