Description

  The present invention relates to a mechanism such as air sterilization capable of killing and / or inactivating bacteria or viruses floating in the air.

Conventionally, there is an air cleaner as shown in Patent Document 1 below. The air cleaner includes a blower, a filter, a heat source device, and a controller. The filter is disposed on the downstream side of the blower, and the heat source device is disposed between the blower and the filter. In this air purifier, the first mode in which only the blower is operated by the controller and the second mode in which the heat source unit and the blower are simultaneously operated can be switched. This air purifier uses the operation mode switching function to collect and concentrate biological particles (for example, viruses and fungi) in the filter in the first mode, and collect biological particles collected and concentrated in the filter in the second mode. It can be inactivated or / and killed. Conventionally, there is also an air cleaner as shown in Patent Document 2 below. This air purifier collects and concentrates viruses, bacteria, and other dust using dust collecting electrodes and HEPA (High Efficiency Particulate Air) filters during operation of the blower fan, and an ozone generator when the blower fan is stopped. It is possible to inactivate or kill viruses and fungi collected and concentrated on the dust collecting electrode and the HEPA filter by operating (closing the casing in some cases). The two air purifiers are common in that they are not temporarily treated with viruses and bacteria, but are inactivated or / and killed after the viruses and bacteria are collected and concentrated.

It becomes. However, in the air cleaner as shown in Patent Document 1, since the entire surface of the filter must be heated at once, if the size is increased, a heater with a large heat capacity is required, resulting in high cost, danger, and waste of energy. There is a problem. Similarly, an air cleaner as disclosed in Patent Document 2 has a problem that a large amount of ozone needs to be generated when the size is increased, resulting in high costs, danger, and waste of energy.

  An object of the present invention is to provide a mechanism such as air sterilization that can realize low cost, safety, and energy saving even when the size is increased.
