(Embodiment 1)
FIG. 1 shows a schematic view of an air purifier according to claims 1 and 2.

  The air purifying apparatus of the present embodiment is provided with an intake port 2 for sucking room air on one side surface of a substantially box-shaped main body case 1 and an outlet port 3 for blowing purified air on the other side surface.

  Inside the main body case 1, in the middle of an air air passage communicating the air inlet 2 and the air outlet 3, the air blowing means 4, the water storage part 5 for storing the chlorine-based compound-containing water, and the chlorine-based compound are supplied to the air. A chlorine-based compound supply unit 6 and a gas processing filter 7 constituted by a fiber holding any one of a compound having a primary amino group, ammonia, and an ammonium salt are provided.

  The air blowing means 4 is formed as a so-called sirocco fan composed of a motor (not shown), an impeller rotated by the motor, and a case surrounding them.

  In addition, as the base material constituting the gas processing filter 7, paper such as cellulose or woody material processed into a corrugated shape, natural fibers such as silk, wool, cotton and hemp, synthesis of rayon, acetate, triacetate, etc. A corrugated fiber or a ceramic honeycomb can be used. For example, for synthetic fibers, polyolefin, polyester, acrylic, nylon, vinylon, rayon, polynosic, cupra, acetate, triacetate, promix, polyvinyl acetate, polyvinyl alcohol sponge, nylon microfiber, polyolefin resin (polyethylene resin, polypropylene resin, etc.) ), PET (polyethylene terephthalate resin), polyamide resin, vinyl chloride resin, fluorine resin (PTFE, PFA, ETFE, etc.) and the like are used.

  The component retained in the gas processing filter 7 is any one of a compound having a primary amino group, ammonia, and an ammonium salt, and among them, sulfamic acid is desirable. This is because sulfamic acid is more stable when it becomes bound chlorine than other substances.

  In addition, the chlorine-based compound supply unit 6 promotes volatilization of chlorine-based compound-containing water, such as an ultrasonic vibrator or a nebulizer, forcibly spraying chlorine-based compound-containing water from the water storage unit 5 into the air duct. The structure which improves gas-liquid contact efficiency so that it may be mentioned. In the present embodiment, a structure in which chlorinated compound-containing water is sucked up by the capillary phenomenon of the filter immersed at one end in the water storage section 5 and the chlorinated compound-containing water volatilizes from the other end of the filter exposed in the air air passage. doing.

  In the above configuration, the operation of the air purification device will be described.

  The chlorinated compound supplied by the chlorinated compound supply unit 6 from the water storage unit 5 that stores chlorinated compound-containing water into the air taken into the main body case 1 from the air inlet 2 by the blower 4 is an air air passage. By reacting with any of the compound having primary amino group, ammonia, and ammonium salt on the gas processing filter 7 installed in the latter stage, it becomes combined chlorine.

  Formula 1 shows a reaction in which sulfamic acid and hypochlorous acid react on the gas processing filter 7 to produce monochlorosulfuramic acid as bound chlorine.

H ₃ NSO ₃ + HClO → H ₂ NSO ₃ Cl + H ₂ O Formula 1
When the combined chlorine formed on the gas processing filter 7 and bacteria, fungi, viruses, odorous substances, etc. contained in the indoor air sucked into the main body case 1 come into contact with each other, sterilization / Since it is deodorized, the purified air is supplied into the room from the outlet 3.

  As described above, in the present embodiment, deodorizing and sterilizing effects can be expressed by supplying the chlorine-based compound to the gas processing filter 7, so that the deodorizing and sterilizing effects are exhibited on the filter when necessary. Since it can be arbitrarily selected not to exert the deodorizing and sterilizing effect when unnecessary, it is possible to suppress the deodorizing and sterilizing effect reduction over time, which are generally problems.

  When it is determined that the room air to be treated contains a large amount of odorous components and microorganisms, the air blowing means 4 is operated, so that the air taken into the main body case 1 from the air inlet 2 by the air blowing means 4 is operated. The chlorine-based compound supply unit 6 supplies the chlorine-based compound-containing water from the water storage unit 5. On the other hand, when the room air is judged to be clean, deodorization and sterilization effects are not required, and if the air blowing means 4 is stopped, the room air does not pass through the air air passage where the chlorinated compound supply unit 6 is installed. Volatilization of chlorine compound-containing water from the chlorine compound supply unit 6 is suppressed. Therefore, since the consumption of chlorine-based compound-containing water is suppressed, it is possible to suppress the deodorization and sterilization effect reduction over time.

  It should be noted that the determination of how much odorous components and microorganisms are contained in the indoor air being treated may be based on the experience of the user, using detection means such as a gas sensor or odor sensor. You may judge.

  In addition, when a structure for forcibly spraying water containing chlorine compound into the air air passage from the water storage unit 5 such as an ultrasonic vibrator or a nebulizer is used as the chlorine compound supply unit 6, it contains chlorine compound when necessary. By spraying water, the deodorizing and sterilizing effect can be exhibited on the gas processing filter, and when it is unnecessary, the deodorizing and sterilizing effect cannot be exhibited unless the chlorine-based compound-containing water is sprayed.

Electrolyzed water can be generated as water containing a chlorinated compound as a representative.

  The generated electrolyzed water is stored in the water reservoir 5 as chlorine-based compound-containing water. As in the first embodiment, the chlorine-based compound supply unit 6 stores the chlorine-based compound-containing water in the air taken into the main body case 1 from the air inlet 2 by the blower 4 and the chlorine-based compound supply unit 6 performs the chlorine-based process. A compound is supplied. As in the first embodiment, the chlorine-based compound supplied into the air becomes combined chlorine by reacting with any of the compound having a primary amino group, ammonia, and ammonium salt on the gas processing filter 7.

  When the combined chlorine formed on the gas processing filter 7 and bacteria, fungi, viruses, odorous substances, etc. contained in the indoor air sucked into the main body case 1 come into contact, the bacteria are sterilized by the action of the combined chlorine. -Since it deodorizes, the purified air will be supplied indoors from the blower outlet 3.

  The chlorine-based compound supplied from the chlorine-based compound supply filter 9 is discharged from the air outlet 3 to the outside of the main body case, and is then disposed in the air air passage when it is sucked into the main body case 1 from the air inlet 2 again. It becomes bound chlorine on the gas processing filter 7 and exhibits deodorizing and sterilizing effects.

  Note that the chlorinated compound released to the outside of the main body case 1 can obtain a deodorizing and sterilizing effect even if the chlorinated compound alone is used indoors, for example.

  In this configuration, the taken-in air is deodorized and sterilized by the gas processing filter 7, and dust removal as a general function of the filter is also performed. The passed air is again deodorized and sterilized by the gas-liquid contact of the chlorine-based compound-containing water on the chlorine-based compound supply filter 9.
