Droplet infection suppression system and droplet infection suppression method
View Patent ↗A droplet infection suppression system includes an airflow generator capable of generating an airflow for separating a space into first regions, a first detector that detects human presence in each of the first regions, a second detector that detects coughing or sneezing in the space, and a controller which, when the second detector detects coughing or sneezing, controls the airflow generator to generate an airflow such that a second region including one or more first regions including a first region where human presence has been detected by the first detector is separated by the airflow from other regions.
1. A droplet infection suppression system comprising:
an airflow generator configured to generate an airflow for separating a space into a plurality of regions;
first detectors corresponding one-to-one to the plurality of regions;
a second detector; and
a controller which, when the second detector detects coughing or sneezing and the first detectors detect human presence in a first region of the plurality of regions, human presence in a second region of the plurality of regions, and no human presence in a third region of the plurality of regions, causes the airflow generator to generate an airflow, wherein
the first region, the second region, and the third region are provided side by side and have no common region,
the third region is provided between the first region and the second region,
one or more additional regions of the plurality of regions are not provided between the first region and the second region,
the airflow separates the first region and the second region, and
the airflow does not separate the first region and the third region.
2. The droplet infection suppression system according to claim 1 , wherein
in a case where the first detectors detect human presence in two or more of the plurality of regions, the controller controls the airflow generator to generate an airflow so as to separate the two or more of the plurality of regions from each other.
3. The droplet infection suppression system according to claim 1 , wherein
in a case where the first detectors detect human presence in two or more of the plurality of regions and the second detector detects coughing or sneezing in one of the two or more of the plurality of regions, the controller controls the airflow generator to generate an airflow such that the one of the two or more of the plurality of regions is separated by the airflow from the other regions.
4. The droplet infection suppression system according to claim 1 , further comprising
a desk, wherein
the airflow generator is included in the desk, and the airflow generator generates an airflow upward from the desk.
5. The droplet infection suppression system according to claim 4 , wherein the airflow generator has a lattice shape in plan view of the desk.
6. The droplet infection suppression system according to claim 4 , wherein the second detector is included in the desk.
7. The droplet infection suppression system according to claim 1 , wherein the second detector includes a microphone or a camera.
8. The droplet infection suppression system according to claim 1 , further comprising
chairs respectively including the first detectors.
9. The droplet infection suppression system according to claim 1 , wherein the first detector includes an infrared sensor or a pressure sensor.
10. A droplet infection suppression method performed using an airflow generator configured to generate an airflow for separating a space into a plurality of regions, first detectors corresponding one-to-one to the plurality of regions, and a second detector, the droplet infection suppression comprising:
when the second detector detects coughing or sneezing and the first detectors detect human presence in a first region of the plurality of regions, human presence in a second region of the plurality of regions, and no human presence in a third region of the plurality of regions, causes the airflow generator to generate an airflow, wherein
the first region, the second region, and the third region are provided side by side and have no common region,
the third region is provided between the first region and the second region,
one or more additional regions of the plurality of regions are not provided between the first region and the second region,
the airflow separates the first region and the second region, and
the airflow does not separate the first region and the third region.
