Description

The present invention relates to an air purifier that purifies air by capturing fine particles floating in the air.

  Recently, health damage caused by aspiration of fine particles such as SARS virus, avian influenza virus and asbestos floating in the atmosphere has become a problem.

  As one method for solving this problem, an air purifier having a HEPA filter has been proposed. This air purifier has a suction part for sucking air containing fine particles and a HEPA filter arranged in a discharge path of air drawn in by the suction part, and uses the HEPA filter to remove fine particles in the air. By capturing, it is configured to discharge the purified air.

  However, since all the air fine particles drawn by the suction part are captured by the HEPA filter, the replacement period of the HEPA filter is shortened and the running cost is increased.

  Then, an object of this application is to provide the air cleaner with low running cost.

  In order to solve the above problems, a first configuration of the present invention is an air purifier that captures particulates contained in the air sucked inward from the outside of the container body and discharges the purified air. The container main body contains water, and oil is disposed on the water. The discharge port has a lipophilic first filter portion and a second filter portion made of a water-absorbing polymer. , And the first filter part is arranged upstream of the second filter part in the discharge direction.

  Here, a guide member for guiding the sucked air may be provided, and the guide member may be extended into the oil or the water.

  Moreover, it is good to arrange | position the grid | lattice-like member provided with the several opening part extended in an up-down direction in the levitation path where the air guide | induced in the said water or oil floats.

  The second configuration of the present invention is an air cleaner that captures particulates contained in the air sucked inward from the outside of the container body, and discharges the purified air. Oil is accommodated, and the discharge port is provided with a fine particle capturing filter for capturing lipophilic fine particles.

  Here, a guide member that guides the sucked air into the oil may be provided.

  Moreover, it is good to arrange | position the grid | lattice-like member provided with the several opening part extended in an up-down direction in the floating path where the air guide | induced in the said oil floats.

  According to the first configuration of the present invention, oil or water adheres to the fine particles (eg, SARS virus, avian influenza virus, asbestos) drawn into the container, and most of them remain in the oil or water, and remain. Since a part of can be captured by the first filter part or the second filter part, the fine particles can be reliably captured.

  In addition, according to the second configuration of the present invention, oil adheres to the fine particles (eg, SARS virus, avian influenza virus, asbestos) drawn into the container, most of the oil remains in the oil, and the remaining part is retained. Since it can be captured by a filter, lipophilic fine particles can be reliably captured.

Embodiments of the present invention will be described below with reference to the drawings.
Example 1
FIG. 1 is a cross-sectional view of an air cleaner. The container body 11 constituting the air purifier 1 is provided with a suction port 11a and a discharge port 11b having a circular opening cross section. A suction fan 12 for sucking air from the outside of the container body 11 to the inside is provided inside the suction port 11a.

  The container body 11 contains water, and oil is disposed on the water. The layer thickness of the oil layer 17 is preferably 10 to 15 mm, and examples of the oil include vegetable oil.

  A guide wall 13 extending toward the lower region of the container is provided at one end of the suction port 11a inside the container, and the guide wall 13 extends into the oil layer 17. Note that the guide wall 13 may be extended into the water layer 18.

  Inside the discharge port 11b, a discharge fan 14 and a filter 15 (particulate trapping filter) are provided in order from the outlet side of the discharge port 11b.

  The filter 15 includes a second filter unit for capturing fine particles to which moisture has adhered and a first filter unit for capturing fine particles to which oil has adhered. The first filter unit is more than the second filter unit. It is arranged on the discharge direction start end side. Here, examples of the trapped microparticles include lipophilic microparticles such as SARS virus, avian influenza virus and asbestos, ionizable substances such as salts and sugars, and hydrophilic microparticles such as surfactants. Since most of the fine particles present in the air are oleophilic, the fine particles in the air can be efficiently captured by disposing the first filter portion upstream of the second filter portion in the discharge direction. Further, hydrophilic fine particles that are not captured by the first filter part can be reliably captured by the second filter part.

  Examples of the material for the first filter part include highly lipophilic materials such as vinylidene chloride, polypropylene, polyethylene, polyester, acrylic, and nylon, and examples of the material for the second filter part include fibrous absorbent polymers.

  The discharge fan 14 and the filter 15 are detachably attached to the discharge port 11b.

  Next, the cleaning operation of the air cleaner 1 will be described. When a power button (not shown) that instructs the air cleaner 1 to start a cleaning operation is turned on, the suction fan 12 and the exhaust fan 14 start rotating.

  The air drawn into the container body 11 by the suction fan 12 is guided into the oil layer 17 while being guided by the guide wall 13. Most of the fine particles in the air led into the oil layer 17 are attached to the oil layer 17 by the oil component, and the rest passes through the oil layer 17 and falls into the water layer 18 below the oil layer 17. To do.

  The fine particles dropped into the oil layer 17 and the water layer 18 pass under the guide wall 13 by the wind sent from the suction fan 12, and move toward the discharge port 11b.

  Most of the fine particles that have passed under the guide wall 13 remain in the oil layer 17 or the water layer 18, but the remaining part is wound up by the rotating action of the exhaust fan 14. Among the rolled up fine particles, the oil is attached to the lipophilic fine particles, and the water is attached to the hydrophilic fine particles.

  When the lipophilic fine particles to which the oil component is attached reach the first filter portion, the lipophilic fine particles are captured by the first filter portion due to the viscous force of the oil component.

  When the hydrophilic fine particles to which moisture adheres reach the second filter portion, a jelly-like object is generated by chemical adsorption between the water-absorbing polymer and water, and the hydrophilic fine particles are captured by the jelly-like object.

  Thereby, since the fine particles in the air can be surely removed, the air can be cleaned.

  In the present embodiment, air containing fine particles is guided to the inside of the container body 11, so that most of the fine particles are captured by the oil layer 17 or the water layer 18, and the remaining fine particles not captured by the oil layer 17 and the water layer 18 are collected. The filter 15 is configured to capture. Therefore, the product life of the filter 15 is extended, and the running cost can be reduced.

  In addition, when water or oil adheres to the fine particles, the particle size may increase and the fine particles may aggregate. As a result, it is not necessary to use a fine filter such as a HEPA filter, the degree of freedom in selecting a filter is increased, and the cost can be reduced as a result.

Furthermore, since air is drawn into the oil and water contained in the container main body 11 and the filter 15 is disposed in the discharge port 11b, particulates in the air can be reliably captured, so that the cleaning effect is high with a very simple configuration. An air purifier can be provided.
(Example 2)
The air cleaner of the present embodiment will be described with reference to FIGS. Here, FIG. 2 is a sectional view of the air purifier, and the same components as those in the first embodiment are denoted by the same reference numerals. FIG. 3 is a perspective view of the lattice member and the suction pipe.

  In these drawings, a suction pipe 34 is connected to the suction port 11 a of the container body 11, and the suction pipe 34 extends into the oil layer 17 and the water layer 18 accumulated at the bottom of the container body 11. Yes.

  The front end of the suction pipe 34 is bent upward, and the discharge port 34a faces upward.

  Above the discharge port 34a of the suction pipe 34, a lattice member 35 having a plurality of openings 35a extending in the vertical direction is disposed. The lattice member 35 is submerged in the water accumulated at the bottom of the container body 11, and the air discharged from the discharge port 34 a is finely divided through the openings 35 a of the lattice member 35. It is like that. In addition, you may arrange | position this grid | lattice-like member 35 so that an upper end part may be on the oil layer 17. FIG.

  In the above-described configuration, when the suction fan 12 is rotated, air is drawn into the container body 11 through the suction port 11a, and the drawn air is discharged from the discharge port 34a through the suction pipe 34.

  The air discharged from the discharge port 34a is finely divided when passing through the openings 35a of the lattice member 35, and moisture or oil adheres to the fine particles contained in the air.

  Most of the fine particles to which moisture or oil is adhered remain in the water layer 18 or the oil layer 17 in the container main body 11, but the remaining part is sucked by the discharge fan 14 and enters the inlet side of the discharge port 11b. The filter 15 provided is reached.

  Thus, in the present embodiment, the air discharged from the discharge port 34a can be finely divided by passing through the openings 35a of the lattice-like member 35. Thereby, oil or water can be easily attached to the fine particles.

  Moreover, the effect described in Example 1 is also acquired.

  In the first and second embodiments, the oil is arranged on the water, but only the oil can be used.
