Description

  The present invention relates to an air cleaner or a deodorizer.

Conventional technology

  Smoke and odor are filled in places where there is a large amount of cigarette smoking, such as a smoking area, or where a lot of odor gas is generated. However, with respect to deodorization, satisfactory performance is not exhibited. Also, if odorous substances adhere to clothes, carpets, walls, etc., it is difficult to remove them with an air cleaner or the like, and odors adhere to clothes even after leaving a smoking area, which is uncomfortable.

  Conventionally, in order to remove odors attached to clothes or the like, a deodorant is sprayed on the clothes with a spray or the like to mask or remove the odors. However, when the liquid is sprayed by spraying, the deodorant is not effectively used because the liquid has a large particle size and a large amount of spray unevenness. In addition, since the liquid has a large particle size, the speed of falling on the floor or the ground is high, and the floating time is short, and it is difficult to adhere to the back side of clothing or the like.

  By the way, electrostatic atomization technology is applied to various fields such as painting and agricultural chemical application. Electrostatic atomization is a phenomenon in which water is atomized when a high voltage is applied to the liquid and the liquid is exposed to an electric field. In this mechanism, when the electric field on the liquid surface increases, a large number of fine droplets are generated by the electrostatic force acting on the surface. When the liquid is finely divided, the surface area per unit mass increases, and at the same time, the liquid droplets are charged to the same polarity, so that the liquid is dispersed over a wide range by repulsive force.

  Therefore, the present invention proposes an air purifier or a deodorizer capable of solving the above-mentioned problems by paying attention to such an electrostatic atomization technique.

  That is, the present invention is characterized in that a negative ion effect is produced by charging a liquid with a negative charge and spraying the liquid when the liquid is electrostatically atomized.

  When the static electricity is charged, the electrostatic atomized liquid can be sprayed over a wide range since the particle size becomes small and the repulsive force works electrostatically. Further, since the sprayed liquid is charged with static electricity, it can be attached to the back side of the clothing.

  Since the current indoor environment is highly airtight, it will stay in the room if it is contaminated with certain fine particles or harmful gases. As countermeasures, air purifiers, deodorizers, and the like are used, but satisfactory effects cannot be obtained when pollutants are constantly discharged.

  In view of this, the invention according to claim 2 includes an electrostatic adsorption unit for adsorbing suspended fine particles and the like with static electricity simultaneously with the liquid sprayed by charging.

  The liquid charged by electrostatic atomization gives electric charge to airborne particulates and harmful gases, so that the harmful substances that are charged can be attracted to the grounded surface and removed from the air. Become.

  Most negative ion generators on the market charge negative ions in the air. Since air has a low dielectric constant, it is difficult to charge it efficiently, and the effects of negative ions cannot be fully exhibited. In addition, products such as ozone are produced. In the present invention, the negatively charged liquid particles are charged in the electrostatic atomization, and since the sprayed liquid has a higher dielectric constant than air, it can be charged efficiently.

BEST MODE FOR CARRYING OUT THE INVENTION

  Next, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a schematic configuration of a deodorant spraying apparatus according to the present invention, in which static electricity is applied to a nozzle 1 for ejecting a liquid deodorant (water droplet 5) and the deodorant (water droplet 5) ejected thereby. The charging unit 2 forms a high-voltage electric field for charging and atomizing, and the high-voltage power source 6 charges the charging unit 2. In this example, the charging unit 2 electrostatically atomizes the water column 3 ejected from the nozzle 1 by the dielectric charging method at the charging electrode 4, that is, by passing a high voltage electric field to reduce the particle size, The water droplets 5 are sprayed as fine particles.

  FIG. 2 shows an example of this. A part of the nozzle 1 is inserted into the cylindrical charging electrode 4, and a high voltage is applied by the high voltage power source 6 using the nozzle 1 as a positive electrode and the charging electrode 4 as a negative electrode. The water droplets 5 of the fine particles ejected from the nozzle are negatively charged and electrostatically atomized. When charged negatively in this way, the negative ion effect can also be exhibited.

  By mixing antioxidants such as vitamin C and bactericides with water droplets 5 and simultaneously spraying them by electrostatic atomization, active oxygen staying in the air can be removed with antioxidants, It can be sterilized with a disinfectant.

  If an AC high-voltage power supply is used as the high-voltage power supply 6, the positive and negative polar charges can be charged to the water droplets 5 of the fine particles, and the charge can be eliminated. If a grounded electrostatic adsorption unit (not shown) is installed at the tip of the charging unit 4 by the charging electrode 4, floating particles in the air can be adsorbed and collected simultaneously with water droplets 5.

  As shown in FIG. 3, when a high voltage is directly applied to the nozzle 1 itself, the water droplet 5 can be directly charged at the same time as spraying by the nozzle 1 using the nozzle 1 itself as a charging unit. Either the structure of FIG. 2 or the structure of FIG. 3 can be used by being incorporated in an air purifier.

  According to the first aspect of the present invention, the liquid can be sprayed in a wide range by electrostatic atomization, and the amount of liquid used can be saved by spraying efficiently. In addition, since the liquid is electrostatically atomized so as to have a negative charge, a negative ion effect can be expected at the same time.

  According to the second aspect of the present invention, the electrostatic atomized liquid has an electric charge, gives electric charge to dust and harmful gas floating in the air, and electrostatically adsorbs the charged dust and harmful gas. It can be adsorbed and removed from the air at the part.

It is a schematic block diagram which shows an example of this invention. It is the outline perspective view. It is a figure which shows the other structural example.
