A home air purifier that purifies air by dust removal (removal of particulate matter) and deodorization will be described as an example. The purifier comprises a device that positively charges fine particles by corona discharge under a strong electric field, collects the charged fine particles by using a negatively charged filter, and deodorizes the fine particles by a deodorizing filter using activated carbon. It had been. In the purifier, the apparatus having the above-described configuration is usually installed on the floor of a living space of a person, and the surrounding air is forcibly ventilated into the purifier by the operation of a fan driven by the built-in electric power. Cleaning was going on. Such a configuration and operation have the following problems. That is, ozone is generated by corona discharge, and even a very small amount of this ozone is harmful to the human body. In charging by discharging, as the particle diameter becomes smaller, the charging efficiency becomes lower. For example, the collection performance of particles of 0.1 μm or less to which viruses are attached and particulate matter of 0.1 μm or less in tobacco smoke is extremely low,
Collection and removal were almost difficult.

The load on the rear filter increases, and a collecting material having a large collecting capacity is required. Since the deodorizing filter deteriorates quickly due to the above-mentioned generated ozone (the ozone reacts with the deodorizing filter), it has many disadvantages such as rapid deterioration of performance. Also,
Since the purifier is installed on the floor and operated by electric power, the space for human activities is limited (reduced), and a large amount of electric power needs to be supplied. On the other hand, the present inventors have proposed a method of charging and collecting fine particles by using photoelectrons generated by irradiating a photoelectron emitting material with ultraviolet rays (eg, Japanese Patent Publication No. 3-5859 and Japanese Patent Publication No. Hei 6-5859). -34941, Tokuhei 6

There was room. In the charging / collecting of the fine particles by the corona discharge method described above, the device by the method is installed on a floor where a person lives, and a strong electric field and forced ventilation of the surrounding air by a fan are required.
(2) The power cost for operating the device is high, (3) Ozone and fine particles are generated by the operation, and the charging efficiency is low (particularly, the particle size is small). (The lower the finer the particle, the lower the performance of removing fine particles).

(5) Comfortable air can be obtained by using sunlight (because a special air purifier is not required), and the activity space (space) for humans has been widened. In addition, since the power cost is only required for forming the electric field, the cost is lower than that of an air purifier in which contaminated air is forcibly ventilated by a conventional fan. In addition, because it is ozone-free and has no particulate generation, it has become a practically effective technology for creating a comfortable living space.
