JP 2012-052699 A

  In an air purification device that removes bacteria, viruses, odors, etc. by bringing this type of electrolyzed water into contact with room air, the contact efficiency between the electrolyzed water and air must be increased in order to increase the sterilization and deodorization effect. Although demanded, increasing the contact efficiency between electrolyzed water and air has a problem of promoting moisture evaporation and humidifying.

  Then, this invention solves the said subject, and it aims at providing the air purification apparatus which can suppress a humidification amount, improving disinfection and deodorizing performance.

  In order to achieve this object, the present invention provides an air purification device, wherein the main body case has an intake port and an outlet, and the air purifier is provided with a blowing means and an air purification means. Is formed from a tray for storing water, an electrolysis unit for generating electrolyzed water with the water in the tray, and a filter part partially immersed in the water in the tray, and from the intake port by the blowing means The sucked air is blown to the outlet through the filter unit, and the filter unit is formed in a hollow cylindrical shape and is rotatably disposed on the tray. The direction enters the electrolyzed water from the downstream side of the flow path and moves to the upstream side of the air flow path.

  By these means, the initial purpose is achieved.

  As described above, according to the present invention, as the air purification device, the main body case has the intake port and the air outlet, and the blower unit and the air purification unit are provided in the main body case, and the air purification unit stores water. Formed in a tray, an electrolysis unit that generates electrolyzed water with water in the tray, and a filter part that is partially immersed in the water in the tray, and the air sucked from the intake port by the blowing means The filter unit is configured to be blown to the outlet through the filter unit, and the filter unit is formed in a hollow cylindrical shape and is rotatably disposed on the tray, and the rotation direction of the filter unit is set downstream of the air flow path.

Then, the filter part that does not contain much water is brought into contact with the downstream side of the air flow path. At this position, the air that contains a relatively large amount of water and the filter part that does not contain a relatively large amount of water contact each other. As a result, the humidification efficiency decreases. Thereby, it is possible to provide an air purification device that suppresses the humidification amount while improving the sterilization effect.

  The air purification means 5 includes a tray 6 for storing water, a water supply tank 7 for supplying water to the tray 6, an electrolysis unit 8 for generating electrolyzed water from the water in the tray 6, and a part of the water in the tray 6. Is formed from the filter part 9 immersed in the filter.

  The tray 6 has a box shape with an opening on the top and has a structure capable of storing water. The tray 6 is disposed at the lower part of the main body case 1 and is detachable by sliding horizontally from the main body case 1. Yes.

  The water supply tank 7 is installed on the front side inside the main body case 1 so as to be built in the tray 6, and is structured to be detachable from the tray 6. The water supply tank 7 has a structure that can be sealed with a cap. However, when the water supply tank 7 is installed on the tray 6, the water tap provided on the cap is released and water is supplied to the tray 6. . When the water surface rises to the faucet, the water supply tank 7 is sealed by the water surface, the supply of water is stopped, and a constant amount of water can always be supplied.

  The electrolysis unit 8 is composed of a plurality of electrode plates, and the electrode plates are installed so as to be immersed in the water in the tray 6. By energizing these electrodes, water containing chloride ions in the tray 6 is provided. Electrolyzed water is generated by electrochemically electrolyzing (in this embodiment, water in which sodium chloride is dissolved in tap water).

  The filter unit 9 is a member that makes the electrolytic water generated by the electrolysis unit 8 in the tray 6 come into contact with the indoor air sucked into the main body case 1 by the blowing means 4. A filter having a cylindrical shape and provided with a hole through which air can flow is arranged in the circumferential portion, and one end of the filter is rotatably incorporated in the tray 6 so as to be immersed in the electrolytic water of the tray 6. And it is the structure rotated by the drive part (not shown), and makes electrolyzed water and room air contact continuously.

  The material constituting the filter unit 9 is a material that is less reactive to electrolyzed water, that is, a material that is less deteriorated by electrolyzed water, such as polyolefin resin (polyethylene resin, polypropylene resin, etc.), PET (polyethylene terephthalate resin). ), Vinyl chloride resin, fluorine-based resin (PTFE, PFA, ETFE, etc.), cellulose-based material, ceramic-based material, or the like is used. In this embodiment, polyester is employed.

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

  Tap water is supplied to the tray 6 by the water supply tank 7. At this time, sodium chloride is simultaneously put into the tray 6 by the user. The water containing chloride ions is energized by the electrolysis unit 8 and electrolyzed to generate electrolyzed water containing active oxygen species.

  Here, the reactive oxygen species are oxygen molecules having an oxidation activity higher than that of normal oxygen and related substances, and the so-called narrow definition such as superoxide anion, singlet oxygen, hydroxy radical, or hydrogen peroxide. The active oxygen includes so-called broadly active oxygen such as ozone and hypochlorous acid (hypohalogenous acid).

  The electrolyzed water soaks the entire filter unit 9 by the rotation of the filter unit 9, and comes into contact with the room air sucked into the main body case 1 from the air inlet 2 by the blower 4.

  Bacteria, fungi, viruses, odorous components, etc. in the air sucked into the main body case 1 together with room air are decomposed, inactivated, etc. by contacting the electrolytic water on the filter unit 9. The purified air is supplied into the room from the outlet 3.

  As shown in FIG. 3, the feature of the present embodiment is that the filter portion 9 is formed in a hollow cylindrical shape and is rotatably arranged on the tray 6, and the rotation direction of the filter portion 9 is electrolyzed from the downstream side of the air flow path. The direction is to enter the water and move to the upstream side of the air flow path.

  That is, in FIG. 3, white arrows indicate the flow of room air, and solid arrows indicate the rotation direction of the filter unit 9.

  In addition, an air flow path in which the water content of the electrolytic water in the filter section 9 is increased by providing a shielding section 10 that shields the upstream and downstream sides of the air flow path in the vicinity of the upper outer surface of the hollow cylindrical filter section 9. The upstream side portion of the air channel is formed to have a surface area larger than that of the downstream side portion, and the upstream wind speed with respect to the filter portion 9 of the air flow path is made slower than the downstream wind speed with respect to the filter portion 9 of the air flow path. is there.

  That is, the filter unit 9 is separated from the air path by the shielding unit 10, and the indoor air passes through the filter unit 9 twice.

  In addition, an attachment frame 11 for fixing the filter portion 9 in a hollow cylindrical shape and a rotating means (not shown) for rotating the attachment frame 11 are provided, and the attachment frame 11 is attached to the attachment frame 11 in the hollow cylinder of the filter portion 9. The rotation shaft 12 is provided at the center of rotation, and the air direction changing means 13 has a structure in which a substantially cylindrical portion is provided in the hollow cylindrical inner portion of the filter portion 9 of the rotation shaft 12. The upstream wind speed with respect to 9 is made slower than the downstream wind speed with respect to the filter portion 9 of the air flow path.

  That is, the inside of the hollow cylinder of the filter portion 9 also functions as an air path, but this wind direction changing means 13 changes a part of the air path, and by changing the pressure loss of the air path, It has a function of changing the wind speed and direction. And in a present Example, it installs so that a wind direction may be changed so that the wind speed of the air of the downstream of the filter part 9 may be accelerated.

  The effect of the characteristic in this embodiment is demonstrated.

  First, the filter portion 9 is formed in a hollow cylindrical shape and is rotatably arranged on the tray 6. The rotation direction of the filter portion 9 enters the electrolyzed water from the downstream side of the air flow path, and the upstream side of the air flow path. The direction to move to.

  As a result, the room air is pumped up while the filter unit 9 rotates, and the room air taken into the main body case 1 is first introduced into the filter unit 9 containing a large amount of electrolyzed water. By increasing the efficiency and bringing bacteria, viruses, odors, and the like contained in room air into contact with electrolyzed water more efficiently, the effect of removing electrolyzed water from bacteria, viruses, odors, and the like can be enhanced. And in the downstream of an air flow path, the filter part 9 which does not contain much water will contact, In this position, the air which contains much moisture on the upstream side, and the filter part which does not contain moisture relatively 9 will come into contact, and the humidification efficiency will be reduced. Thereby, it is possible to provide an air purification device that suppresses the humidification amount while improving the sterilization effect.

  Moreover, by making the upstream wind speed with respect to the filter section 9 of the air flow path slower than the downstream wind speed with respect to the filter section 9 of the air flow path, the indoor air is more in contact with the electrolyzed water, so that sterilization, deodorization, etc. On the upstream side of the high-efficiency filter unit 9, the sterilization and deodorizing effect can be enhanced by slowing the wind speed and increasing the contact time of air and electrolyzed water. Furthermore, the downstream side of the filter part 9 in the air flow path has a high wind speed, and the contact time between the air and the filter part is shortened, so the humidification amount in this part can be further reduced, so the humidification efficiency is Will go down. Thereby, it is possible to provide an air purification device that suppresses humidification performance while improving the sterilization effect as a whole.

  Specifically, a shielding portion 10 that shields the upstream side and the downstream side of the air flow path is provided in the vicinity of the upper outer surface of the hollow cylindrical filter portion 9, and the water content of the electrolytic water in the filter portion 9 increases. By forming the upstream portion of the air flow path with a larger surface area than the downstream portion, the wind speed on the upstream side with respect to the filter portion 9 of the air flow path is made slower than the wind speed on the downstream side with respect to the filter portion 9 of the air flow path. It is something that can be done.

  Thereby, on the upstream side of the filter unit 9 where the indoor air is more in contact with the electrolyzed water, the wind speed is slowed down and the contact time between the air and the electrolyzed water is taken for a longer time, thereby enhancing the sterilization and deodorizing effect. . Furthermore, the downstream side of the filter portion 9 in the air flow path has a high wind speed, and the contact time between the air and the filter portion 9 is shortened, so the amount of humidification in this portion can be further reduced, so the humidification efficiency Will go down. Thereby, it is possible to provide an air purification device that suppresses humidification performance while improving the sterilization effect.

  In addition, a mounting frame 11 for fixing the filter unit 9 in a hollow cylindrical shape and a rotating means for rotating the mounting frame 11 are provided, and a wind direction changing unit 13 is provided in the mounting frame 11 in the hollow cylinder of the filter unit 9. The air velocity distribution of the indoor air with respect to the filter unit 9 can be freely set, and the configuration in which the wind speed to the filter unit 9 is slowed on the upstream side and the wind speed is made fast on the downstream side as described above. Can be realized. Thereby, on the upstream side of the filter unit 9 where the indoor air is more in contact with the electrolyzed water, the wind speed is slowed down and the contact time between the air and the electrolyzed water is taken for a longer time, thereby enhancing the sterilization and deodorizing effect. . Furthermore, since the wind speed is fast on the downstream side of the filter portion 9 in the air flow path, and the humidification amount in this portion can be further reduced, the humidification efficiency is lowered. Thereby, it is possible to provide an air purification device that suppresses humidification performance while improving the sterilization effect.

  Further, the mounting frame 11 is provided with a rotating shaft 12 at the center of rotation for rotating the mounting frame 11, and the wind direction changing means 13 is provided with a substantially cylindrical portion in the hollow cylindrical portion of the filter portion 9 of the rotating shaft 12. The air passage cross-sectional area in the portion 9 is smaller than the air passage cross-sectional area on the upstream side of the filter portion 9. The air passage cross-sectional area is an area on a plane perpendicular to the direction in which air flows.

  Thereby, the structure which slows the wind speed to the filter part 9 in the above-mentioned upstream, and speeds up the wind speed in the downstream can be realized with a simple structure.

  That is, the sterilization and deodorizing effect can be enhanced by slowing the wind speed on the upstream side of the filter unit 9 where the room air comes into contact with the electrolyzed water and taking the contact time between the air and the electrolyzed water for a longer time. Furthermore, since the wind speed is fast on the downstream side of the filter portion 9 in the air flow path, and the humidification amount in this portion can be further reduced, the humidification efficiency is lowered. Thereby, it is possible to provide an air purification device that suppresses humidification performance while improving the sterilization effect.

  As described above, according to the present embodiment, it is possible to provide an air purification device that can suppress the humidification amount while improving the sterilization and deodorization performance, with a simple configuration at low cost.

  The filter part is formed in a hollow cylindrical shape, and is rotatably disposed on the tray. The direction of rotation of the filter part enters the electrolyzed water from the downstream side of the air flow path and moves to the upstream side of the air flow path. By doing so, it is possible to provide an air purification device that can suppress the amount of humidification while improving the sterilization and deodorization performance at a low cost with a simple configuration.

  Therefore, it is expected to be used as an air purification device for sterilization and deodorization for home use, office use, public space, and the like.
