[Examples]

As shown in FIG. 1 and FIG. 2, an air purification method according to an embodiment of the present invention The machine 1 has a main body portion 11, a front panel 12, and a rear panel 14. The main body portion 11 includes a top plate 11a, a right side panel 11b, a left side panel 11c, and a bottom portion 11d which are formed of a synthetic resin material, and are formed in a substantially rectangular parallelepiped shape. The front panel 12 is a molded product of a synthetic resin material and is disposed on one surface of the main body portion 11. The rear panel 14 is a molded product of a synthetic resin material and is disposed on the other surface of the main body portion 11. In the following description, the side of the main body portion 11 on which the front panel 12 is disposed is referred to as the front side of the main body portion, and the side of the main body portion 11 on which the rear panel 14 is disposed is referred to as the rear portion of the main body portion. side.

A front panel 13 as a molded material of a synthetic resin material is disposed in front of the front panel 12. An upper suction port 13a, a right side suction port 13b, and a left side suction port 13c which are air intake ports of the air cleaner 1 of the present embodiment are formed between the front panel 13 and the front panel 12. Further, between the main body portion 11 and the rear panel 14, an upper air outlet 14a, a right side air outlet 14b, and a left side air outlet 14c which are air blowing ports of the air cleaner 1 of the present embodiment are formed. In the air cleaner 1, the air sucked into the main body portion 11 from the upper suction port 13a, the right side suction port 13b, and the left side suction port 13c is blown into the room from the upper air outlet 14a, the right side air outlet 14b, and the left side air outlet 14c. Blow it out. During this period, air dedusting, humidification, and deodorization are performed.

As shown in FIG. 3 and FIG. 4, the inside of the main body portion 11 that communicates the upper suction port 13a, the right side suction port 13b, the left side surface suction port 13c, the upper surface air outlet 14a, the right side air outlet 14b, and the left side air outlet 14c The space becomes the ventilation duct 10 of the air cleaner 1 of this embodiment.

On the upper surface of the air cleaner 1 to cover the upper suction port 13a The operation unit 15 is provided in a part of the manner. A button for operating the air cleaner 1 such as a power button and an operation mode switching button is disposed on the operation unit 15. Further, a display unit is disposed on the operation unit 15. The display unit displays the detection state of the operation state of the air cleaner 1 and a detector such as a dust sensor (not shown).

As shown in Fig. 3, in the ventilation passage 10 inside the main body portion 11 of the air cleaner 1, a strainer 21, a dust collecting unit 22, a deodorizing unit 23, and humidification are sequentially disposed from the air suction port to the air blowing port. Unit 24 and fan 25.

The strainer 21 is formed of a mesh structure by, for example, braiding a linear PET (polyethylene terephthalate) material. The strainer 21 traps dust contained in the air that is taken into the inside of the main body portion 11. As shown in Fig. 4, the strainer 21 has an arch shape that is convex toward the front side of the main body portion. When the strainer 21 has an arch shape, the coarse filter 21 that passes through the upper suction port 13a, the right side suction port 13b, and the left side suction port 13c into the air inside the main body portion 11 passes through the coarse filter 21 when the strainer 21 has a flat shape. The area is large. Therefore, the strainer 21 is capable of trapping more dust.

As shown in FIGS. 3 and 5, the dust collecting unit 22 includes a first electronic dust collector 22a and a second electronic dust collector 22b. The first electronic dust collector 22a and the second electronic dust collector 22b are arranged side by side in the vertical direction. The first electronic dust collector 22a and the second electronic dust collector 22b have a discharge electrode and a dust collecting electrode (not shown). The first electronic dust collector 22a and the second electronic dust collector 22b charge the fine dust pollen or the like which is not collected by the strainer 21 by the corona discharge generated by the discharge electrode, and collect the charged dust by the dust collecting electrode. Pollen, etc. The first electronic dust collector 22a and the second electronic dust collector 22b are mainly composed of The discharge electrode, the dust collecting electrode, and the casing holding the same. Therefore, the air resistance of the dust collecting unit 22 is small as compared with the dust collecting filter composed of the non-woven fabric formed into the pleated shape described in the prior art. In addition, in FIG. 5, the drawing of the front panel 13 is abbreviate|omitted so that the dust collection unit 22 (1st electronic dust collector 22a and the 2nd electronic dust collector 22b.

As shown in FIGS. 3, 4, and 6, the deodorizing unit 23 has a deodorizing filter 23a and a heating unit 23f as a heating means. As shown in FIG. 6, the deodorizing filter 23a has a disk-shaped base material 23aa having a porous structure such as a wavy structure or a honeycomb structure. The wavy structure has, for example, a flat plate shape that alternately overlaps and a curved member that is continuously curved into a wave shape. A catalyst layer 23ab that adsorbs and decomposes an odor component is provided on the substrate 23aa. As shown in FIGS. 3 and 4, the heating portion 23f includes a PTC (Positive Temperature Coefficient) heater 23b, two heat radiating plates 23c, two heat insulating members 23d, and two outer casings 23e. The PTC heater 23b is mounted on the heat dissipation plate 23c disposed on the front side of the main body portion of the two heat dissipation plates 23c. The PTC heater 23b heats the two heat radiating plates 23c. The two heat radiating plates 23c are metal plates each formed into a substantially triangular shape. As shown in FIGS. 3 and 4, the two heat radiating plates 23c are disposed to cover a part of the deodorizing filter 23a. The two heat radiating plates 23c are in contact with the portion located at the center of the deodorizing filter 23a and the outer diameter side of the deodorizing filter 23a. Therefore, the PTC heater 23b heats not only the heat radiating plate 23c disposed on the front side of the main body but also the heat radiating plate 23c on the back side of the main body. The heat insulating member 23d is disposed to cover the PTC heater 23b and the heat radiating plate 23c. The heat from the PTC heater 23b and the heat sink 23c is suppressed from being radiated to the outside by the heat insulating member 23d. Housing 23e shape The shape of the PTC heater 23b, the heat dissipation plate 23c, and the heat insulating member 23d can be maintained.

Thereby, the deodorizing filter 23a has a porous structure. Further, in the configuration of the deodorizing filter 23a, the heating portion 23f covers only a part of the deodorizing filter 23a. Therefore, the air resistance of the deodorizing filter 23a is small.

When the deodorizing ability of the deodorizing filter 23a is regenerated, the two heat radiating plates 23c are heated by the PTC heater 23b. At this time, a part of the deodorizing filter 23a covered by the two heat radiating plates 23c is heated. The motor (not shown) rotates the deodorizing filter 23a to heat the deodorizing filter 23a. Thereby, the decomposition of the odor component adsorbed on the catalyst layer 23ab of the deodorizing filter 23a is promoted. Thereby, the deodorizing ability of the deodorizing filter 23a is regenerated. Alternatively, instead of rotating the deodorizing filter 23a, the deodorizing filter 23a may be heated by moving the heat radiating plate 23c. Further, the deodorizing unit 23 is not limited to the above unit. For example, the heating device (the PTC heater 23b and the heat dissipation plate 23c) may not be provided. In this case, instead of the catalyst layer, a deodorizing unit comprising a deodorizing filter to which a base material of an odor component adsorbing material such as activated carbon is added may be used. Also, when the adsorption capacity is lowered, a new deodorizing filter can be replaced.

As shown in FIGS. 3, 4, and 6, the humidifying unit 24 has a humidifying filter 24a and a water storage container 24b for storing water. The humidification filter 24a is formed in a disk shape. The humidification filter 24a is rotatably supported by the rotating shaft in a state where a part of the water is immersed in the water stored in the water storage container 24b. The humidification filter 24a is rotated by a motor (not shown). Thereby, the water sucked from the water storage container 24b by the suction bucket provided on the outer circumference of the humidification filter 24a, The humidification filter 24a is wetted. In addition, the humidifying unit 24 may not have the above structure. The humidifying unit 24 may have a humidifying filter that absorbs moisture by capillary action instead of the humidifying filter 24a. In addition, in FIG. 6, in order to clearly show the deodorizing unit 23 and the humidifying unit 24, the front panel 13, the member which comprises the main-body part 11 except the bottom part 11d, and the drawing of the dust collection unit 22 etc. are suitably ab

As shown in FIGS. 3, 4, and 7, the fan 25 has a turbo fan 25a and a fan motor 25b. The turbo fan 25a is formed of a synthetic resin material and is connected to the output shaft of the fan motor 25b. The fan motor 25b is a motor of a variable speed type. When the fan motor 25b is rotated, the turbo fan 25a also rotates. By the rotation of the turbo fan 25a, air is caused to flow into the interior of the air cleaner 1, and air flows out from the inside of the air cleaner 1. In addition, in FIG. 7, the front panel 13, the member contained in the main-body part 11 except the bottom part 11d, the dust collection unit 22, the deodorizing unit 23, and humidification are suitably ab Drawing of unit 24 and the like.

In the air cleaner 1 having the configuration described above, if the user operates the operation unit 15 to start the operation of the air cleaner 1, the fan 25 is driven, and the first electronic dust collector that starts the dust collection unit 22 is started. 22a and the second electronic dust collector 22b are energized. Further, the humidification filter 24a of the humidification unit 24 starts to rotate. When the fan 25 is driven, air is taken into the inside of the main body portion 11 from the upper suction port 13a, the right side suction port 13b, and the left side suction port 13c.

The air sucked into the inside of the main body portion 11 flows in the following manner.

(1) in the ventilation passage 10, in the lower portion of the deodorizing unit 23 and humidification The upper portion of the unit 24 is overlapped in the front-rear direction, and the air flows in the order of the coarse filter 21 → the dust collecting unit 22 → the deodorizing unit 23 → the humidifying unit 24.

(2) In the ventilation duct 10, the deodorizing unit 23 and the humidifying unit 24 are not overlapped in the front-rear direction (that is, the lower portion of the deodorizing unit 23 and the upper portion of the humidifying unit 24 are overlapped in the front-rear direction). Other than the air, the air flows in the order of the coarse filter 21 → the dust collecting unit 22 → the deodorizing unit 23, or the order of the coarse filter 21 → the dust collecting unit 22 → the humidifying unit 24.

After the air that has entered the inside of the main body portion 11 flows as (1) or (2), the air is blown out from the upper air outlet 14a, the right side air outlet 14b, and the left side air outlet 14c to the room where the air cleaner 1 is installed.

As described above, when the air passes through the ventilation passage 10 inside the air cleaner 1, the dust filter 21 and the energized dust collecting unit 22 are used to remove dusty pollen or the like. Further, the odor component is removed by the deodorizing unit 23, and the passing air is humidified by the humidifying unit 24. Further, as described above, the dust collecting unit 22 is disposed closer to each air suction port than the deodorizing unit 23. Therefore, the air that has flowed into the deodorizing unit 23 is air from which dust and pollen are removed. Therefore, the deodorizing filter 23a of the deodorizing unit 23 is not blocked by dust or pollen.

The arrangement of the deodorizing unit 23 and the humidifying unit 24 will be further described in detail with reference to FIGS. 3 and 6 . As shown in FIG. 3 and FIG. 6, the deodorizing unit is a part of the deodorizing filter 23a included in the deodorizing unit 23 and a part of the humidifying filter 24a of the humidifying unit 24 overlapping the ventilation direction. 23 and the humidifying unit 24 are sequentially disposed along the ventilation passage 10 in the ventilation passage 10. Specifically, the deodorizing unit 23 is disposed in the ventilation passage 10 The upper portion of the humidification unit 24 is disposed at a lower portion of the ventilation passage 10. At this time, the two units are disposed in the ventilation passage 10 in the ventilation direction so that the lower portion of the deodorizing filter 23a and the upper portion of the humidifying filter 24a overlap in the front-rear direction with respect to the ventilation direction (part A of FIG. 3). Thus, by disposing the deodorizing unit 23 and the humidifying unit 24, it is possible to perform deodorization and humidification, and it is possible to reduce the size of the casing and suppress the ventilation resistance. Further, a part of the deodorized air can be humidified by the humidification filter 24a. Further, the deodorizing unit 23 is disposed at an upper portion of the ventilation passage 10, and further, the humidifying unit 24 is disposed at a lower portion of the ventilation passage 10. By arranging in the above-described manner, as shown in FIG. 6, the heating unit 23f of the deodorizing unit 23 and the water storage container 24b of the humidifying unit 24 can be disposed at positions separated from each other. Therefore, when the humidifying unit 24 sucks the water stored in the water storage container 24b by the rotation of the humidifying filter 24a to wet the humidifying filter 24a, the sucked water does not scatter to the heating portion 23f of the deodorizing unit 23. .

As shown in FIG. 6, the deodorizing unit 23 is disposed on the upper side of the wind of the humidifying unit 24. The deodorizing unit 23 has a holding portion 23g that holds the deodorizing filter 23a so as to be rotatable. The internal shape of the holding portion 23g is formed into a cylindrical shape along the shape of a disk of the deodorizing filter 23a. Further, the outer shape thereof is formed in a rectangular shape. Further, a vent hole 23ga (ventilating portion) for ventilating the air inside the main body portion 11 is formed in a portion of the lower portion of the holding portion 23g that overlaps the humidifying filter 24a with respect to the ventilation direction. In addition, a slit may be formed as a ventilating portion instead of the vent hole 23ga. As described above, the deodorizing unit 23 is disposed on the upper side of the humidifying unit 24 toward the wind. Therefore, the deodorizing list is not blocked by the air containing moisture after humidification. Deodorizing filter 23a of element 23.

Further, the humidifying unit 24 can control the wet state of the humidifying filter 24a by controlling the driving of a motor (not shown). When the operation mode switching button of the operation unit 15 is pressed and only the deodorizing operation mode is selected, the driving of the motor (not shown) is stopped. Therefore, the rotation of the humidification filter 24a is stopped, and the humidification operation of the air is stopped by stopping the supply of water to the humidification filter 24a.

Further, as described above, the air cleaner 1 of the present embodiment has the dust collecting unit 22 composed of two electronic dust collectors, and the deodorizing unit 23 configured to cover only a part of the deodorizing filter 23a with the two heat radiating plates 23c. And a fan 25 having a turbo fan 25a. Further, as described above, the dust collecting unit 22 has a small ventilation resistance as compared with the dust collecting filter including the non-woven fabric formed into a pleated shape described in the prior art. Further, the ventilation resistance of the deodorizing unit 23 is small as compared with the deodorizing unit having the plate-shaped heating portion formed to have substantially the same area as the catalyst filter explained in the prior art.

Further, not only the ventilation resistance of the dust collecting unit 22 and the deodorizing unit 23 is small, but as shown in FIGS. 3 to 7 , two units are disposed such that a part of the deodorizing unit 23 and a part of the humidifying unit 24 overlap each other. Thus, even when the dust collecting unit 22, the deodorizing unit 23, the humidifying unit 24, and the fan 25 are arranged in this order from the air suction port to the air blowing port, the ventilation resistance does not become large. Therefore, the turbo fan 25a can be used for the fan 25, which has a lower static pressure than the sirocco fan, that is, the turbofan 25a has a smaller air volume than the sirocco fan when it has the same ventilation resistance, but efficiency High and low noise. Therefore, the air cleaner 1 capable of ensuring the required dust collecting ability and deodorizing ability and suppressing noise can be realized. In addition, the turbo fan 25a does not require a spiral casing that the sirocco fan has. Thereby, the air cleaner of the present invention can be made smaller and thinner than the sirocco fan. Therefore, it is possible to further prevent the size of the casing of the air cleaner 1 from becoming large. Further, as described above, the respective structural members (the dust collecting unit 22, the deodorizing unit 23, the humidifying unit 24, and the blower 25) are arranged in this order along the ventilation passage 10, and the size of the main body portion 11 in the front-rear (depth) direction becomes long. Further, each of the air suction ports is disposed on the front side of the main body portion 11, and each of the air blowing ports is disposed on the back side of the main body portion 11. Therefore, the distance L between each of the air suction ports and the air blowing ports shown in FIG. 4 can be increased. Thereby, the air blown into the room from each air outlet is suppressed from being immediately taken into the air cleaner 1 from the air intake ports, that is, the occurrence of a short circuit between the air intake port and the air outlet port is suppressed.

In the air cleaner 1, it is possible to realize a distance L in which the above short circuit is unlikely to occur. Therefore, the air cleaner 1 may have an upper suction port 13a and a right side suction port for taking air into the interior of the air cleaner 1 from three directions of the upper end portion, the right end portion, and the left end portion of the front portion of the main body portion 11. 13b and the left side suction port 13c. Further, the air cleaner 1 may have an upper air outlet 14a, a right side air outlet 14b, and a left side air outlet 14c for blowing air from the upper end portion, the right end portion, and the left end portion of the rear portion of the main body portion 11 in three directions. . Therefore, the area of the air intake port and the air outlet port can be increased. As a result, the air cleaner 1 can sufficiently ensure the intake amount and the amount of air blown. In addition, the air cleaner 1 performs three By sucking and blowing out the air in the direction, the air in the room in which the air cleaner 1 is installed can be sucked into the room to collect dust, humidify, and deodorize, and the purified air can be blown into the room.

Further, as shown by the line segment P in Fig. 3, it is preferable that the height of the center of the fan motor 25b is matched with the height of the space between the first electronic dust collector 22a and the second electronic dust collector 22b of the dust collecting unit 22, Dust collecting unit 22 and fan 25. The flow of air generated by the rotation of the turbo fan 25a in the vicinity of the center of the fan motor 25b is small. Therefore, in the space near the center of the fan motor 25b inside the main body portion 11, the flow of air is small. On the other hand, the space between the first electronic dust collector 22a and the second electronic dust collector 22b in the dust collecting unit 22 has no dust collecting ability with respect to the passing air. Therefore, by matching the height of the space with the height of the center of the fan motor 25b, the first electronic dust collector 22a and the second electronic dust collector 22b can be disposed in a space where the blades of the turbo fan 25a having a large amount of air flow. Thereby, the dust removal by the dust collection unit 22 can be performed efficiently.

As described above, in the air cleaner 1 of the present embodiment, the two units are in the ventilation passage 10 such that the lower portion of the deodorizing filter 23a and the upper portion of the humidifying filter 24a overlap in the front-rear direction with respect to the ventilation direction. The inner edge is arranged in the ventilation direction. Therefore, deodorization and humidification can be performed, and the ventilation resistance can be suppressed, and the main body portion 11 as the casing of the air cleaner 1 can be prevented from becoming large. Further, a vent hole 23ga is formed in a lower portion of the holding portion 23g of the deodorizing unit 23. Therefore, even in the portion where the lower portion of the deodorizing unit 23 and the upper portion of the humidifying unit 24 are overlapped, the ventilation resistance can be suppressed.

Further, the air cleaner of the embodiment of the present invention may be the following One to three air purifiers.
