- the humidifying filter 22 since the humidifying filter 22 is disposed on the front surface of the blower 25, the humidifying filter 22 can be easily removed and removed by removing the air cleaning filter unit 20 so that the humidifying filter 22 can be easily cleaned or replaced. .
- the humidifying part 21 is arranged on the front surface of the blower 25, the humidifying part 21 can be installed downward. The For this reason, it is possible to prevent failure of electrical components due to leakage of the tray 23 and the water tank 24.
- FIGS. 17 (a) and 17 (b) are a top view and a front view showing the humidifying filter 22.
- the humidifying filter 22 has a water-absorbing material power having water absorption, and is formed in a folding screen shape that is zigzag bent in the front-rear direction. As a result, the humidifying filter 22 sucks up the water in the tray 23 and retains it.
- Each wall surface of the humidifying filter 22 that extends in the front-rear direction by bending is bonded with a predetermined gap by an adhesive 22b such as hot melt.
- the adhesive 22b is provided so as to be disposed near the opening of the tray 23 or inside the tray 23 when the humidifying filter 22 is inserted into the tray 23.
- a double cam-like air passage 22c is formed above the tray 23 in a plan view extending in the vertical direction between the wall surfaces of the humidifying filter 22, and the air passage 22c is directed upward from below. The air moves by force.
- the lower air that has passed through the air cleaning filter unit 20 collides with the humidifying filter 22, and the back side is shielded, so the arrow B along the folded wall surface of the water absorbing material (see Fig. 2).
- the downward force also rises upward in the air passage 22c.
- the water retained in the humidification filter 22 is vaporized and taken into the air flowing through the air passage 22c, and the humidified air flows into the ventilation path 31 through the vent 27.
- the humidification part 21 is a vaporization system.
- ions released from the ion generator 26 and water molecules are mixed in the main body of the air cleaner 1. As a result, it is sent out from the air outlets 29 and 30 of the main body into the room in a state surrounding the water molecular force ON.
- the state of air on the ion emission surface of the ion generator 26 reaches the ion emission surface due to water mixed with the air that has passed through the humidifying filter 22.
- This air When the air volume of the blower 25 is “strong”, it contains about 200 cm 3 Zh of water, and when the air volume is low, it contains about 50 cm 3 Zh of water. As a result, the relative humidity increases by 5 to 10% compared to the surrounding environment.
- a mode in which positive ions and negative ions are sent into the room and a mode in which only negative ions are sent into the room can be switched by operating the operation panel 15 (see FIG. 1).
- positive ions and negative ions can be sent into the room to sterilize and remove odors from the floating bacteria floating in the room.
- the mode can be switched to send negative ions into the room for a relaxation effect.
- the periphery of the ion i delivered into the room is surrounded by water molecules h.
- the force that the particle diameter d is estimated to be 2 to 3 nm. It is estimated that For this reason, airborne sterility bacteria, such as viruses, and ions i The degree of impact increases.
- the ion i collides with dust in the air, the ion i is protected by the water molecule h, and disappearance is reduced. Therefore, the floating bacteria in the room can be quickly removed.
- FIG. 19 shows the result of measuring the residual rate of airborne bacteria when positive ions and negative ions are sent into the room.
- the vertical axis shows the residual rate of airborne bacteria (unit:%), and the horizontal axis shows the drive time (unit: min) of the air purifier 1.
- the test was conducted at a high air flow (approximately 6. Om, humidification amount 2 OOcmV).
- the size of the room is 3m wide x 3.5m deep x 2.5m high.
- R1 indicates the case where ions are not delivered.
- R2 indicates the case where ions are sent without being humidified by the humidifying unit 21! /.
- R3 shows a case where ions are sent while being humidified by the humidifying unit 21.
- Fig. 20 shows the result of measuring the residual rate of odorous components by conducting a deodorization test when positive ions and negative ions are sent into the room based on the Japan Electric Industry Standard JEM1467. Yes.
- the vertical axis indicates the residual rate of odor components (unit:%), and the horizontal axis indicates the drive time (unit: min) of the air cleaner.
- the odor components are ammonia, acetic acid and acetonitrile.
- the test was carried out with the air volume increased (approximately 6.0 m 3 Zh, humidification amount 200 cm 3 Zh) with the air cleaning filter unit 20 removed.
- S1 indicates the residual rate of odor components when air containing no moisture is sent
- S2 indicates the residual rate of odor components when air containing moisture is sent. According to the figure, one hour after the start of the test, the effect of reducing the total residual rate by 15 to 18% was obtained compared to air without water.
- ions i collide with fibers such as clothes, curtains, sofas, etc. ions i are surrounded by moisture molecules h, so that they are protected, and the disappearance of ions is reduced. Therefore, ions surrounded by water molecules enter deep inside the fiber, and the attached odor components are removed. It can be surrounded and destroyed to remove odors quickly and efficiently.
- the deodorizing test was carried out with a test cloth at a point 1.5m in front of the outlet 30 with a strong air flow (approx. 6. Om, humidification amount 200cm 3 Zh).
- a strong air flow approximately 16% to 24% compared to when not humidified.
- the filter can be used for an air conditioner such as an air purifier or an air conditioner that collects dust and sends out ions into the room.
- an air conditioner such as an air purifier or an air conditioner that collects dust and sends out ions into the room.
