In the above-mentioned conventional air purification device, since a large amount of water is used and vaporized, there is a problem that the amount of humidification increases and the humidity of the room rises too much.

Therefore, the present invention solves the above-mentioned conventional problems, and the air purifying filter includes two fiber base materials having different thicknesses of fibers forming openings, and a base material having thick fibers forming openings. By using the main fiber base material and the base material having fine fibers as the sub fiber base material and arranging the main fiber base material upstream of the air cleaning filter, an air purifying device having high deodorizing performance while having a low humidification amount can be obtained. The purpose is to provide.

In order to achieve this object, the air purification apparatus of the present invention, flow and air air passage for communicating the suction plug mouth and blow outlet, the air toward the air-air duct in the blowing outlet from suction plug mouth and blowing means, and the air cleaning filter of a rotatable cylindrical which is provided in the empty air flow path so as to block the air-air path, and a driving unit for rotating the air-purifying filter, air-purifying rotated by the drive movement unit the lower portion of the filter is closed and the water tank which can be immersed in water. Air cleaning filter includes a main fiber base material formed on the first grating shape having a first opening, a sub fiber base formed in the second grating shape having a larger second opening of the opening area than the first opening It is composed of a material and a bonding layer using a monofilament between a main fiber base material and a sub fiber base material. The main fiber substrate is disposed upstream of the sub fiber substrate in air air passage. The main fiber base material and the sub fiber base material are in a state where the first lattice-shaped lattice portion and the second lattice-shaped lattice portion are superimposed when viewed from the direction orthogonal to the surface of the air cleaning filter. It is characterized in that the first opening and the second opening are arranged so as to communicate with each other, thereby achieving the intended purpose.

According to the present invention, while a low humidification amount, it is possible to provide an air purification device having a high deodorizing performance.

When a collision occurs between the indoor air flowing in the air air passage and the water contained in the air purifying filter, the dirt components contained in the indoor air flowing in the air air passage dissolve in the water on the air purifying filter, and deodorization is promoted. Will be done. Since the thick base material contains a large amount of fresh water, by arranging the base material with thick fibers upstream of the air cleaning filter, the absorption rate of dirt components at the time of collision is increased and the efficiency of deodorization is improved. If the fibers at the time of the first collision are thick, the opening becomes small and the air passage is narrowed, so that the probability of collision between the fibers containing water and the indoor air flowing in the air air passage is high. As the number of collisions increases, turbulence is generated on the surface of the air purification filter, and the chances of collision between the indoor air flowing in the air air passage and the main fiber base material increase, so that deodorization is performed efficiently. The sub-fiber base material also holds a small amount of water, which contributes to the improvement of deodorizing performance. However, because the fiber is thinner than the main fiber base material and it is difficult to hold water, it is deodorized without increasing pressure loss or humidification amount. Performance can be improved. As a result, it is possible to have high deodorizing performance while having a low humidification amount.

Air purification device according to the present invention includes an air air passage for communicating the suction plug mouth and blow outlet, a blower means for flowing the air toward the air-air duct in the blowing outlet from suction plug mouth, to block the air-air path an air cleaning filter of a rotatable cylindrical which is provided in the empty air flow passage, a driving unit for rotating the air cleaning filter, the lower portion of the air cleaning filter is rotated by the driving pivot portion can be immersed in water to Yes and the water tank, the. Air cleaning filter includes a main fiber base material formed on the first grating shape having a first opening, a sub fiber base formed in the second grating shape having a larger second opening of the opening area than the first opening It is composed of a material and a bonding layer using a monofilament between a main fiber base material and a sub fiber base material. The main fiber substrate is disposed upstream of the sub fiber substrate in air air passage. The main fiber base material and the sub fiber base material are in a state where the first lattice-shaped lattice portion and the second lattice-shaped lattice portion are superimposed when viewed from the direction orthogonal to the surface of the air cleaning filter. It is characterized in that the first opening and the second opening are arranged so as to communicate with each other. As a result, when the indoor air flowing in the air air passage collides with the water contained in the air cleaning filter, the dirt component contained in the indoor air flowing in the air air passage dissolves in the water on the air cleaning filter. Deodorization is promoted.

In addition, since the thick base material contains a large amount of fresh water, by arranging the base material with thick fibers upstream of the air cleaning filter, the absorption rate of dirt components when indoor air collides is increased and the deodorization efficiency is increased. Will improve.

Further, if the fibers at the time of the first collision of the indoor air are thick, the opening becomes small and the air passage is narrowed, so that the collision probability between the fibers containing water and the indoor air flowing in the air air passage is high. As the number of collisions increases, turbulence is generated on the surface of the air purification filter, and the chances of collision between the indoor air flowing in the air air passage and the main fiber base material increase, so that deodorization is performed efficiently.

In addition, although the sub-fiber base material exists on the downstream side of the air purification filter, the fibers are thin and have a structure that makes it difficult to retain water, so that the deodorizing performance and strength of the main fiber base material are not increased without increasing pressure loss or humidification amount. Can be secured.

In addition, capillarity does not occur between monofilaments, water is no longer retained in the thickness direction of the air purification filter, vaporization is unlikely to occur even if indoor air and the air purification filter come into contact, and deodorization is performed with a low humidification amount. be able to.

As a result, it is possible to have high deodorizing performance while having a low humidification amount.

In particular, by connecting the base materials with monofilaments and arranging them at intervals between the monofilaments, it is possible to prevent the phenomenon of having water between the monofilaments. Can be secured.

Further, by increasing the strength of the air purifying filter, the durability of the air purifying filter is increased, and the air purifying filter can be used for a long time without deterioration.

Humidification is also promoted by lengthening the contact time and allowing the wind to flow as if stroking between the air purifying filters. Therefore, by thinning the fibers on the downstream side, the contact time is shortened, which has the effect of suppressing the amount of humidification. As a result, it is possible to have high deodorizing performance while having a low humidification amount.

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

(Embodiment 1)
As shown in FIG. 1, the air purification device of the present embodiment includes a substantially box-shaped main body case 1. A substantially square suction port 2 is provided on both side surfaces of the main body case 1, a substantially square air outlet 3 is provided on the top surface of the main body case 1, and a suction port 3 is provided in the main body case 1. Immerse the air air passage 4 that communicates 2 and the air outlet 3, the air blowing means 5 that allows air to flow from the suction port 2 to the air outlet 3 in the air air passage, the air cleaning filter 6, and the lower part of the air cleaning filter 6. A water tank 7 is provided. The air purifying filter 6 has a rotatable tubular shape and is provided so as to block the air air passage 4. The air cleaning filter 6 includes two fiber base materials 9 having different thicknesses of the fibers forming the opening 8 shown in FIG. 2, and one of the two fiber materials has a thick fiber forming the opening 8. The main fiber base material 10 is a sub-fiber base material 11 in which the fibers forming the openings 8 are thin, and the main fiber base material 10 is arranged upstream of the sub-fiber base material 11. As the air cleaning filter 6 is rotated by the drive unit 16 (rotating in the direction indicated by the arrow A), the air cleaning filter 6 contains water when it comes out of the water tank 7.

As shown in FIG. 3B, the tubular shape is formed by cutting the original fabric of the main fiber base material 10 into a quadrangle and joining the opposite ends to each other to form an endless shape.

The blower means 5 is provided on the upper part of the main body case 1 and is formed as a so-called sirocco fan composed of a motor, an impeller rotated by the motor, and a case surrounding the motor.

The water tank 7 has a box shape with an open top surface and has a structure capable of storing water. It is arranged at the bottom of the main body case 1 and can be attached and detached by sliding horizontally from the main body case 1. There is.

The drive unit 16 shows the shape of a gear provided at the center of rotation of the air purifying filter 6, and transmits the rotational operation of a motor (not shown) or the like to the air purifying filter 6 to rotate the air purifying filter 6 in the A direction. It is the one that drives.

The air cleaning filter 6 is formed by the main fiber base material 10 shown in FIG. 2 (a) and the sub fiber base material 11 shown in FIG. 2 (b), and both the main fiber base material 10 and the sub fiber base material 11 are fibers. The main fiber base material 10 has an opening 8 made of thick fibers, and the sub fiber base material 11 has an opening 8 made of fibers finer than the fibers of the main fiber base material 10. The opening area of the opening 8 of the sub-fiber base material 11 is larger than the opening area of the opening 8 of the main fiber base material 10.

With this configuration of the air purifying filter 6, after the air comes into contact with the main fiber base material 10, the air can pass through without being hindered by the sub fiber base material 11, so that the pressure loss can be small.

Further, the opening 8 may be a polygon such as a triangle, a quadrangle, or a hexagon. In such a configuration, the main fiber base material 10 and the sub fiber base material 11 can be continuously provided with openings having a similar shape or the same size, and a continuous opening 8 can be obtained without forming a closed portion. Can be done. As a result, the air is less likely to be obstructed by the air purifying filter 6 in the air air passage 4, and the pressure loss is reduced.

Further, as shown in FIG. 3A, the air purifying filter 6 is formed so close that the main fiber base material 10 and the sub fiber base material 11 have a predetermined space between them. In FIG. 3A, for ease of explanation, the main fiber base material 10 is shown by a thick black line, and the sub fiber base material 11 is shown by a thin white solid line. The lattice shape formed by the main fiber base material 10 and the lattice shape formed by the sub fiber base material 11 overlap. As a result, when a collision occurs between the indoor air flowing in the air air passage and the water contained in the air cleaning filter 6, the dirt component contained in the indoor air flowing in the air air passage becomes the water on the air cleaning filter 6. It dissolves and promotes deodorization. Since the thick main fiber base material 10 contains a large amount of fresh water, by arranging the thick main fiber base material upstream of the air cleaning filter 6, the absorption rate of dirt components at the time of collision is increased and deodorization is performed. It will be more efficient. Further, if the fibers at the time of the first collision are thick, the opening becomes small and the air passage is narrowed, so that the collision probability between the fibers containing water and the indoor air flowing in the air air passage 4 is high. As the number of collisions increases, turbulence is generated on the surface of the air purifying filter 6, and the chances of the indoor air flowing in the air air passage 4 colliding with the main fiber base material 10 increase, so that deodorization is efficiently performed. Although the sub-fiber base material 11 exists on the downstream side of the air cleaning filter 6, the fibers are thin and have a structure that makes it difficult to retain water. Therefore, the deodorizing performance of the main fiber base material 10 and the deodorizing performance without increasing the pressure loss and the amount of humidification are achieved. The strength can be guaranteed.

As a result, it is possible to have high deodorizing performance while having a low humidification amount.

In addition, unlike the present embodiment, when two fiber base materials having thick fibers are bonded to each other as the air cleaning filter 6, the pressure loss is high, the contact is increased, and the humidification amount is also increased. Not suitable for the purpose.

Further, when the thin fiber base material is installed on the upstream side of the air cleaning filter 6 and the thick fiber base material is arranged on the downstream side of the air cleaning filter 6, the thin fiber base material having a small amount of retained water is placed in the air air passage 4. The indoor air flowing through the air passage 4 hits and turbulent flow occurs, and the indoor air flowing in the air air passage 4 collides with the thin fiber base material, but the chances of collision on the base material with a small amount of water increase, so the air is polluted. The component does not easily dissolve in the water in the fiber, and the deodorizing efficiency deteriorates.

Further, when both the upstream side and the downstream side of the air purifying filter 6 are made of a fiber base material having a thickness intermediate between fine fibers and thick fibers, the indoor air flowing in the air air passage 4 has less collision with the fibers and is opened. The air passing through 8 increases. Furthermore, since the fibers retain a certain amount of water, the humidification efficiency is improved, so that the structure is not suitable for this purpose.

Further, if a thin fiber base material is used for both the upstream side and the downstream side of the air purifying filter 6, the indoor air flowing in the air air passage has less collision with the fibers, and the fibers contain almost no water, so the opening 8 is opened. The amount of air passing through increases, the humidification efficiency and deodorizing performance decrease, and the structure is not suitable for this purpose.

Therefore, by installing the base material with thick fibers on the upstream side of the air cleaning filter 6 and the base material with thin fibers on the downstream side of the air cleaning filter, a large amount of fresh water is contained and the base material with thick fibers is used for air cleaning. By arranging it upstream of the filter 6, the absorption rate of the dirt component when the indoor air collides is increased, and the deodorizing efficiency is improved. Further, if the fibers at the time of the first collision of the indoor air are thick, the opening becomes small and the air passage is narrowed, so that the collision probability between the fibers containing water and the indoor air flowing in the air air passage is high. As the number of collisions increases, turbulence is generated on the surface of the air purification filter, and the chances of the indoor air flowing in the air air passage 4 colliding with the base material having thick fibers increase, so that deodorization is efficiently performed. The sub-fiber base material 11 exists on the downstream side of the air cleaning filter 6, but because the fibers are thin and it is difficult to retain water, the deodorizing performance of the main fiber base material 10 without increasing the pressure loss or the amount of humidification. And the strength can be guaranteed. As a result, it is possible to have high deodorizing performance while having a low humidification amount.

Further, the air cleaning filter 6 is such that the openings 8 of the fiber base material 9 communicate with each other when viewed from a direction orthogonal to the surface of the fiber base material 9 formed by the main fiber base material 10 and the sub fiber base material 11. Is formed.

As a result, the indoor air flowing in the air air passage 4 can pass through without being hindered by the subfiber base material 11, so that the pressure loss can be kept small.

Further, the main fiber base material 10 and the sub fiber base material 11 may be formed of two different types of fiber members. As the material constituting the main fiber base material 10 and the sub fiber base material 11, paper or wood material such as cellulose, natural fibers such as silk, wool, cotton and linen, synthetic fibers such as rayon, acetate and triacetate are used. be able to. For example, synthetic fibers include polyolefin, polyester, acrylic, nylon, vinylon, rayon, polynosic, cupra, acetate, triacetate, promix and the like. Examples of natural fibers include silk, hair, cotton and linen. In this embodiment, polyester is used as the material of the fiber base material for both the main fiber base material 10 and the sub fiber base material 11.

Next, FIG. 3B shows a schematic view of the tubular air purifying filter 6. The air purifying filter 6 has a tubular shape, and the tubular shape may be a cylindrical shape or an elliptical tubular shape as shown in FIG. By using a highly flexible air purifying filter as in this configuration, the shape becomes free, the degree of freedom in the shape of the main body case 1 is expanded, and the main body case 1 can be made compact.

FIG. 3C shows a schematic side view of the tubular air purifying filter. Since the air cleaning filter 6 is provided in the air air passage in a rotatable shape, the indoor air that has passed through the main fiber base material 10 and the sub fiber base material 11 in this order is again subjected to the sub fiber base material 11 and the main fiber base material 11. The material 10 is passed through in order, but since the odor component of the indoor air after once passing through the main fiber base material 10 and the sub fiber base material 11 has already been deodorized by the fiber base material 9, after that, Even if it passes through the sub-fiber base material 11 and the main fiber base material 10 in order, the contribution to deodorization is low. That is, it is important that the main fiber base material 10 is arranged on the upstream side of the sub fiber base material 11 at the portion where the indoor air and the main fiber base material 10 first come into contact with each other.

In the present embodiment, the air purifying filter 6 has two fibers, a main fiber base material 10 made of thick fibers and a sub fiber base material 11 made of fibers thinner than the fibers of the main fiber base material 10. Although the configuration in which the base materials are brought close to each other is illustrated, the air cleaning filter 6 is not limited to the configuration of the present embodiment, and a plurality of layers of fiber base materials may be provided. In this case, the air purifying filter may have a structure in which the fiber base materials made of the thickest fibers are brought close to each other in order from the fiber base material made of the thickest fibers.

(Embodiment 2)
Next, a case where the air purifying filter is provided with a bonding layer using a monofilament will be described. In FIG. 5, FIG. 5 (a) shows a front view of the opening, and FIG. 5 (b) shows a side view of the opening.

As shown in FIG. 5, a bonding layer 13 using the monofilament 12 is formed between the main fiber base material 10 and the sub fiber base material 11 of the air purifying filter, and the main fiber base material 10 and the sub fiber base material 11 are formed. Are held at intervals. The main fiber base material 10 and the sub fiber base material 11 are both made of fibers, the main fiber base material 10 has an opening 8 made of thick fibers, and the sub fiber base material 11 is made of fine fibers. It has an opening 8, and the opening area of the opening 8 of the sub-fiber base material 11 is larger than the opening area of the opening 8 of the main fiber base material 10.

This configuration increases the stability of the shape of the main fiber base material 10 and improves the durability against deformation that may occur repeatedly during cleaning of the air cleaning filter 6.

The bonding layer 13 is bonded in a state where the main fiber base material 10 and the sub fiber base material 11 of the air cleaning filter 6 do not come into direct contact with each other and a space is provided between the main fiber base material 10 and the sub fiber base material 11. The positions of the openings 8 of the joined main fiber base material 10 and the openings 8 of the sub fiber base material 11 coincide with each other in the direction orthogonal to the surface of the base material.

The number of monofilaments 12 may be changed according to the application and durability. In particular, it is preferable that the monofilaments 12 are spaced apart from each other, and it is preferable that the fibers are spaced apart from each other so that the capillary phenomenon does not occur. As a result, water is not retained in the thickness direction of the air purifying filter 6, and vaporization is unlikely to occur even if the indoor air comes into contact with the air purifying filter 6, thereby providing high deodorizing performance while having a low humidification amount. Can be done.

Further, since the bonding layer 13 does not retain water and has an effect only for connecting the main fiber base material 10 and the sub fiber base material 11, the water content retained in the air cleaning filter 6 is small and the pressure loss is low.

Examples of the material constituting the monofilament 12 include polyolefin, polyester, acrylic, nylon, vinylon, rayon, polynosic, cupra, acetate, triacetate, and promix. In the present embodiment, nylon is adopted as the material of the monofilament 12.

The operation of the air purifying device when the air purifying filter in which the bonding layer 13 made of the monofilament 12 is formed between the main fiber base material 10 and the sub fiber base material 11 will be described with reference to FIG.

The basic operation of the air purifying device is as described in the first embodiment, and the configuration of the air purifying filter 6 is replaced with the air purifying filter shown in FIG. 5 described above.

That is, when the air blowing means 5 blows air into the air air passage 4 from the suction port 2, the indoor air is sucked into the main body case and passes through the air purifying filter 6.

At that time, odorous substances and the like contained in the indoor air sucked into the main body case 1 come into contact with the main fiber base material 10 upstream of the air purifying filter 6, are captured, and are deodorized.

As described above, in the above-mentioned first and second embodiments, tap water is used as a medium for deodorization, but even electrolyzed water containing active oxygen species can similarly enhance the sterilization effect in addition to the deodorization effect. it can. The air purification device in this case is shown in FIG. In addition to the air purification device having the same basic configuration as the air purification device shown in the first embodiment, the water tank 7 is provided with the electrode unit 14. In such an air purification device, by charging the water tank 7 and the sodium chloride tablet 15, the water containing chloride ions is energized by the electrode unit 14 including the electrode, electrolyzed, and the active oxygen species are generated. Produces electrolyzed water containing.

Here, reactive oxygen species are oxygen molecules having higher oxidative activity than ordinary oxygen and related substances, and are in the so-called narrow sense such as superoxide anion, singlet oxygen, hydroxy radical, or hydrogen peroxide. Active oxygen contains so-called active oxygen in a broad sense such as ozone and hypochlorous acid (hypohalogenic acid), and is known to exhibit a high sterilizing effect.

Since the main fiber base material 10 of the air purifying filter 6 contains an appropriate amount of electrolyzed water, it is possible to enhance the sterilization effect in addition to the deodorizing effect.

It is expected to be used as an air purification device for removing odors, etc. for home use, office use, public spaces, etc.
