Description

  The present invention relates to an air cleaner, and more particularly, to an air cleaner provided with an ion generator.

  Indoor air is polluted with various substances such as dust, cigarette smoke, and carbon dioxide discharged with breathing. In recent years, airtightness has been enhanced in houses in recent years, and such pollutants tend to accumulate in the room, and it is necessary to actively ventilate the room air.

  However, in a house or office in an area where air pollution is relatively severe, it is not preferable to open a window and ventilate instead of taking dirty air into the room. In addition, even in a house or the like in an area where air pollution is not severe, pollen is taken into the room depending on the season, which is not preferable for people with hay fever.

  Therefore, an air purifier is used to clean indoor air without opening a window. As a method for purifying indoor air, a general method is to suck indoor air, collect dust with a filter, and adsorb contaminants with activated carbon or the like. Therefore, the following basic structure is adopted for the air cleaner.

  That is, a blower passage having a blower is provided in the main body of the air cleaner, and an air suction port is disposed at the inlet of the blower passage, while a blowout port is disposed at the outlet of the blower passage. And a dust collection filter and a deodorizing filter are each arrange | positioned in the middle of a ventilation path. Furthermore, an ion generator is disposed in the middle of the air passage, and ions generated by the ion generator are released into the room together with clean air. Mold fungi floating in the room are surrounded and inactivated by the released ions. Thus, the indoor air is purified by the air cleaner. Such an air cleaner is proposed in Patent Document 1, for example.

As shown in FIGS. 2 and 3, two air outlets 14, a first air outlet 14 </ b> A and a second air outlet 14 </ b> B, are provided in the upper portion of the main body casing 2. The outlet 14 is an opening for blowing the air cleaned by the air cleaner 1 to the outside of the air cleaner 1.

  Next, the internal structure of the air cleaner 1 will be described. As shown in FIGS. 4 and 5, in the air cleaner 1, a space formed by the main body casing 2 is divided into a front space S <b> 1 on the side where the front panel 24 is located and a rear space S <b> 2 on the back side. A partition wall 7 is located. Between the partition wall 7 and the front panel 24, a highly functional filter 28 including three components, a deodorizing filter, a formaldehyde adsorption filter, and an antibacterial / dust collecting filter, is disposed. The high function filter 28 is disposed in the recess 6 provided on the front side of the main casing 2 and divides the front space S1 into two in the front-rear direction. The front space S <b> 1 communicates with the outside of the air cleaner 1 via the suction port 12 on the side of the main body casing 2.

  On the other hand, as shown in FIGS. 4 to 6, a sirocco fan 18 is disposed behind the partition wall 7. The sirocco fan 18 is rotationally driven by a motor 20 disposed behind the sirocco fan 18. The communication hole 8 provided in the partition wall 7 is provided to face the suction surface of the sirocco fan 18. A rear fan cover 10 is attached to the partition wall 7 so as to cover the sirocco fan 18. The rear side fan cover 10 and the partition wall 7 constitute an air passage 13.

  An ion generator 22 that generates at least one of positive ions and negative ions is provided at a predetermined position of the partition wall 7 in the air passage 13. Ions generated by the ion generator 22 are released to the outside of the air purifier 1 along the air flow.

(the flow of air)
Next, the flow of air in the air cleaner 1 will be described. First, when the sirocco fan 18 is rotationally driven by the motor 20, negative pressure is generated in the front space S1 of the main casing 2 and, as shown in FIG. 5, through the suction port 12 located on the side of the main casing 2. Indoor air is taken into the front space S1.

  As shown in FIGS. 4 and 5, the air taken into the front space S1 is subjected to deodorization treatment, formaldehyde adsorption treatment, dust collection treatment and antibacterial treatment when it passes through the high-functional filter 28, and is divided into partitions. It passes through a communication hole 8 provided in the wall 7. Next, the air that has passed through the communication hole 8 is blown outward from the peripheral surface of the sirocco fan 18, as shown in FIG. 4 or FIG. The air thus blown out is guided to the blowout port 14 by the blower passage 13 and is sent out into the room together with the ions generated by the ion generator 22. 4 to 6, such a series of air flows is indicated by arrows (outlined).

The third side plate portion 10d faces the second side plate portion 10c and extends away from the second side plate portion 10c from the other end side in the circumferential direction of the first side plate portion 10b toward the outlet port 14. The second side plate portion 10c has a deflecting portion 11 inclined toward the third side plate portion 10d so that a component of the wind that tends to flow in the tangential direction has a component toward the third side plate portion 10d. Is provided.

  Moreover, the ion generator 22 is attached to the part of the partition wall 7 right under the 2nd blowing outlet 14B. As shown in FIGS. 4 and 8, the ion generator 22 is fixed by a predetermined presser 23 in a state where the surface electrodes 22a and 22b for generating ions are inclined so as to face downward. The presser 23 is provided with an inclined portion 23c corresponding to this inclination and openings 23a and 23b exposing the surface electrodes 22a and 22b. Furthermore, the surface electrodes 22a and 22b are arranged in a direction intersecting with the flow of air (white arrow) flowing in the air passage 13.

As shown in FIGS. 6 and 7, the air outlet 14 is disposed immediately above the sirocco fan 18 and includes a first air outlet 14A and a second air outlet 14B. The first outlet 14A is disposed on the end plate portion 10a side of the rear fan cover 10, and the second outlet 14B is disposed on the partition wall 7 to which the ion generator 22 is attached.

  In particular, the first outlet 14A is formed so as to surround the side and rear (back side) of the second outlet 14B. The opening length W of the blowout port 14 (first blowout port) in the direction orthogonal to the rotation shaft 18 a of the sirocco fan 18 is set to be larger than the diameter D of the sirocco fan 18. In addition, louvers 16A, 16B, and 16C for adjusting the direction of air are provided in each of the first outlet 14A and the second outlet 14B. The louvers 16A, 16B, and 16C also have a function of preventing troubles and taking safety measures such as preventing foreign matter from entering the air passage and preventing hands and fingers from entering.

(Ion generator)
As shown in FIG. 9, the ion generator 22 provided in the middle of the ventilation path 13 is comprised by the case main body 22c and the ion generating element (not shown) inserted in the case main body 22c. A drive circuit for driving the ion generating element, a booster coil, and the like are incorporated in the case body 22c. The ion generating element is configured as a laminated body in which predetermined dielectrics are laminated. On the surface of the laminate, for example, a plurality of mesh-like surface electrodes 22a and 22b are arranged in one direction. One direction in which the surface electrodes 22a and 22b are arranged intersects the flow of air to be sent out. On the other hand, a plate-like back electrode (not shown) is disposed on the back surface of the laminate.

By applying an alternating voltage between the front electrode and the back electrode, oxygen or moisture in the air is ionized by receiving energy by ionization, and H ⁺ (H ₂ O) _m (m is an arbitrary natural number) and O Ions mainly composed of ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number) are generated. The generated ions are released into the room from the outlet by the wind generated by the sirocco fan. These released H ⁺ (H ₂ O) _m and O ₂ ⁻ (H ₂ O) _n adhere to the surface of planktonic bacteria and chemically react with H ₂ O ₂ or (.OH) as an active species. Generate. Since H ₂ O ₂ or (.OH) shows extremely strong activity, they can surround and inactivate airborne bacteria in the air. Here, (.OH) is one kind of active species, and represents radical OH.

The positive ions and the negative ions cause a chemical reaction on the cell surface of the floating bacteria as shown in the formulas (1) to (3) to generate hydrogen peroxide H ₂ O ₂ or a hydroxyl radical (· OH) is produced.
H ⁺ (H ₂ O) _m + O ₂ ⁻ (H ₂ O) _n → OH + _1/2 O ₂ + (m + n) H ₂ O (1) H ⁺ (H ₂ O) _m + H ⁺ (H ₂ O) _{m ^{'+ O 2 - (H 2}} O) n + O 2 - (H 2 O) n' →
2.OH + O ₂ + (m + m ′ + n + n ′) H ₂ O (2)
H ⁺ (H ₂ O) _m + H ⁺ (H ₂ O) _{m ′} + O ₂ ⁻ (H ₂ O) _n + O ₂ ⁻ (H ₂ O) _{n ′} →
H ₂ O ₂ + O ₂ + (m + m ′ + n + n ′) H ₂ O (3)
Here, in Formula (1)-Formula (3), m, m ', n, and n' are arbitrary natural numbers. Thereby, floating bacteria are destroyed by the action of decomposing active species. Therefore, the floating bacteria floating in the air efficiently are inactivated and can be removed.

  Thus, floating bacteria and the like are destroyed by the release of positive ions and negative ions, and the floating bacteria in the air can be sterilized efficiently. In the air cleaner mentioned above, the sterilization effect of floating bacteria etc. can be acquired by the above mechanism.

Further, since the above formulas (1) to (3) can cause the same action even on the surface of harmful substances in the air, hydrogen peroxide H ₂ O ₂ or hydroxyl radical (.OH) which is an active species. However, by oxidizing or decomposing harmful substances, chemical substances such as formaldehyde and ammonia can be converted into harmless substances such as carbon dioxide, water, and nitrogen.

  In addition, positive ions and negative ions have a function to inactivate viruses such as Coxsackie virus and polio virus, and can prevent contamination due to contamination of these viruses. In addition, it has been confirmed that positive ions and negative ions have a function of decomposing molecules that cause odors, and can be used for indoor deodorization.

  In the air cleaner 1 described above, as shown in FIG. 6 or FIG. 7, two outlets 14 of a first outlet 14A and a second outlet 14B are provided as outlets. The first outlet 14A is disposed on the side of the end plate portion 10a of the rear fan cover 10 facing the partition wall 7, and the second outlet 14B is a part of the partition wall 7 to which the ion generator 22 is attached. Is disposed immediately above. Therefore, the air containing the ions generated by the ion generator 22 is mainly guided to the second outlet 14B, and air having a relatively high ion concentration is blown out from the second outlet 14B. From 14A, air having a relatively low ion concentration is blown out.

  The opening length W in the direction perpendicular to the rotation shaft 18 a of the sirocco fan 18 at the first outlet 14 </ b> A is set larger than the diameter D of the sirocco fan 18. At this time, the air sent out from the sirocco fan 18 toward the outlet 14 by centrifugal force tends to flow along the second side plate portion 10c extending in the tangential direction from the substantially arc-shaped first side plate portion 10b. The deflecting portion 11 provided on the second side plate portion 10c generates a component of the air flow toward the third side plate portion 10d.

  Thereby, it is suppressed that the amount of air blowing on the second side plate portion 10c side in the first outlet 14A is larger than the amount of air blowing on the third side plate portion 10d side, as shown in FIG. The air is blown out more uniformly over the opening length W of the first outlet 14A. In this way, the air 40 and 41 are blown out from the outlet 14 so that the air 41 having a relatively low ion concentration surrounds both sides and the rear side (back side) of the air 40 having a relatively high ion concentration. Will be.

  Further, as shown in FIG. 8, the surface electrodes 22a and 22b of the ion generator 22 are arranged in a direction intersecting with the air flow (white arrow), so that the air sent from the sirocco fan 18 has a plurality of air. No longer passes on the surface electrode, and the ions generated at one surface electrode located upstream of the flow are attenuated by interference with the ions generated at the other surface electrode located downstream of the flow. There is no longer to do.

  Further, the ion generator 22 is fixed to the partition wall 7 in a state where the surface electrodes 22a and 22b are inclined downward, so that the air sent from the sirocco fan 18 is directly applied to the surface electrodes 22a and 22b. In this case, the generated ions are not attenuated due to retention or the like. Thereby, the generated ions can be efficiently sent out of the air cleaner 1.

  Further, the ion generator 22 is inclined so that the surface electrodes 22a and 22b face downward, so that even if water or the like enters from the outlet 14 of the air purifier 1, the surface electrodes 22a and 22b. Can be prevented from getting wet, and a high voltage applied to the surface electrodes 22a and 22b can be maintained, and ions can be stably generated. Furthermore, adhesion of dust or the like due to water wetting of the surface electrodes 22a and 22b can be prevented.

  Then, as shown in FIGS. 10 and 11, air 41 having a low ion concentration from the first outlet 14A so as to surround the side and the rear of the air 40 having a high ion concentration blown from the second outlet 14B. The air 41 having a low ion concentration exhibits a function as an air curtain, and reaches the corners of the room more uniformly without directly hitting the air 40 having a high ion concentration directly on the wall of the room. And can be effectively sterilized and sterilized by ions.

  As shown in FIG. 11, the second outlet 14B employs fixed louvers 16B and 16C as louvers. In addition to this, a louver capable of changing the outlet angle is provided. May be. Thereby, the freedom degree of the blowing direction of air with high ion concentration is raised, As a result, the blowing of the air according to the shape and size of a room can be performed, and more effective air purification is performed. be able to.
