Abstract

To provide an air cleaner having sufficient dust collection capability and deodorization capability and capable of suppressing noise. An air cleaner (1) comprises a dust collection unit (22), a deodorization unit (23), and a blower (25). The dust collection unit (22) includes two electric dust collectors having low air resistance. In the deodorization unit (23), two radiator plates (23c) cover only part of a deodorization filter (23a). For this reason, the deodorization unit (23) has low air resistance. Accordingly, even if the blower (25) has a relatively quiet turbofan (25a), a sufficient air flow rate can be ensured, and therefore sufficient dust collection capability and deodorization capability can be obtained.

Description

Air Purifier

The present invention relates to an air purifier that purifies air that is drawn into the interior of a tank and sends the purified air out of the room.

In the air purifier, the air in the main body casing is sequentially passed through the dust collecting filter, the humidifying unit, and the deodorizing unit, for example, by the driving of the fan provided in the main body casing (for example, refer to Japanese Laid-Open Patent Publication No. 2014-52084 number).

The air cleaner described in Japanese Laid-Open Patent Publication No. 2014-52084 has a blowing passage that guides air sucked into the main body casing from the air intake port to the air blowing port. A prefilter, a dust collecting filter, a deodorizing unit, a humidifying unit, and a fan are disposed in the air blowing passage in a direction from the air suction port toward the air blowing port.

The prefilter is formed, for example, by braiding a linear PET (polyethylene terephthalate) material, and has a mesh structure. The dust collecting filter is composed of, for example, a nonwoven fabric formed in a pleated shape. The humidifying unit includes: a humidifying filter having a pleated shape; and a water storage container that supplies water to the humidifying filter. The deodorizing unit includes a catalyst filter that adsorbs and decomposes the odor component, and a heating portion that covers the entire catalyst filter. In the deodorizing unit, the catalyst filter is heated by the heating portion to remove the catalyst filter Flavor ability regeneration. The fan has a variable speed fan motor and a sirocco fan connected to the output shaft of the fan motor.

By the driving of the fan, the air sucked into the air supply passage from the air suction port passes through the prefilter and the dust collecting filter, and at this time, the dust contained in the air is removed. Further, the air passing through the dust collecting filter is humidified while passing through the humidifying unit. Further, the air that has passed through the humidifying unit passes through the deodorizing unit, and at this time, the odor component contained in the air is removed. As described above, the purified air is blown out from the air outlet to the room by the driving of the fan.

In the air cleaner described in Japanese Laid-Open Patent Publication No. 2014-52084, a sirocco fan having a high static pressure is used. Therefore, even if a dust collecting filter and a deodorizing unit having a large air resistance are used, the amount of air required for air purification can be ensured. However, as described above, the sirocco fan has a high static pressure. Therefore, there is a limit in improving the quietness of the air cleaner. On the other hand, for a fan having a low static pressure, it is difficult to ensure the air volume required for air purification due to the air resistance of the dust collecting filter and the deodorizing unit, and it may be impossible to obtain sufficient dust collecting ability and deodorizing ability.

A front baffle 13 made of a synthetic resin material is disposed in front of the front panel 12. A gap is formed in four places of the upper, lower, left, and right sides between the front bezel 13 and the front panel 12. The gaps of the four portions are respectively formed on the front side of the upper side, the bottom surface, the left side surface, and the right side surface of the casing. The gap formed on the front side of the upper side of the casing is the upper suction port 13a. The gap formed on the front side of the right side surface of the casing is the right side suction port 13b. The gap formed on the front side of the left side surface of the casing is the left side suction port 13c.

Further, a gap is formed at three locations on the upper, left, and right sides between the main body portion 11 and the rear panel 14. The gaps of the three portions are formed on the back side of the upper side, the left side, and the right side of the case, respectively. The gap formed on the back side of the upper side surface of the casing is the upper air outlet 14a. The gap formed on the back side of the right side surface of the casing is the right side air outlet 14b. The gap formed on the back side of the left side surface of the casing is the left side air outlet 14c. The upper air outlet 14a, the right side air outlet 14b, and the left side air outlet 14c are air blowing outlets of the air cleaner 1 of the present embodiment that send air from the cabinet toward the outside. In other words, the air blowing port of the air cleaner 1 includes an upper air outlet 14a, a right side air outlet 14b, and a left side air outlet 14c formed on the back side of the casing. In other words, the air blowing port of the air cleaner 1 is disposed on the upper side surface, the left side surface, and the right side surface on the back side of the casing.

In addition, the upper air outlet 14a, the right side air outlet 14b, and the left side air outlet 14c which are air outlets of the air cleaner 1 are a part of a gap (gap) between the main body part 11 and the rear panel 14.

In the air cleaner 1, the air in the main body portion 11 is sucked (sucked in) from the upper suction port 13a, the right side suction port 13b, the left side suction port 13c, and the bottom surface suction port 13d from the upper air outlet 14a and the right side air outlet 14b and the left side air outlet 14c are blown out into the room. The air is dedusted, humidified, and deodorized while the air is sucked into the main body portion 11 from the air suction port and blown out from the air blowing port to the room.

As shown in FIGS. 3 and 4, the upper suction port 13a, the right side suction port 13b, the left side surface suction port 13c, the bottom surface suction port 13d, the upper surface air outlet 14a, the right side air outlet 14b, and the left side air outlet 14c are communicated. Lord The space inside the body portion 11 serves as the ventilation passage 10 of the air cleaner 1 of the present embodiment. In addition, in the following description, each suction port side of the ventilation duct 10 is made into the upstream side, and each blower side is a downstream side, as needed.

The operation portion 15 is provided on the upper side surface of the casing of the air cleaner 1 so as to cover a part of the upper suction port 13a. 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 operation state of the air cleaner 1 and the detection results of 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 prefilter 21, a dust collecting unit 22, a deodorizing unit 23, and a humidifying unit 24 are disposed in this order from the upstream side toward the downstream side. And fan 25.

The prefilter 21 is formed, for example, by braiding a linear PET material, and has a mesh structure. The prefilter 21 removes (or traps) dust contained in the air taken in to the inside of the main body portion 11. As shown in Fig. 4, the prefilter 21 has an arch shape that is convex toward the front side of the main body portion. When the prefilter 21 has an arch shape, the pre-filter 21 has an arch shape, and the inside of the main body portion 11 is sucked from the upper suction port 13a, the right side suction port 13b, the left side suction port 13c, and the bottom surface suction port 13d. The area of the prefilter 21 through which the air passes becomes large. Therefore, the prefilter 21 can remove more dust.

As shown in FIGS. 3 and 5, the dust collecting unit 22 includes a first electric dust collector 22a and a second electric dust collector 22b. The first electric dust collector 22a and the second electric dust collector 22b are arranged in the vertical direction. First electric dust collector 22a The second electric dust collector 22b has a discharge electrode and a dust collecting electrode (not shown). The first electric dust collector 22a and the second electric dust collector 22b charge the fine dust and pollen which are not removed by the prefilter 21 by the corona discharge generated by the discharge electrode, and remove the charged dust by the dust collecting electrode. And pollen, etc. The first electric dust collector 22a and the second electric dust collector 22b are mainly composed of the discharge electrode, the dust collecting electrode, and a case holding the same. Therefore, the air resistance of the dust collecting unit 22 is smaller than the air resistance of the dust collecting filter composed of the non-woven fabric formed into a pleated shape.

In addition, in FIG. 5, in order to clearly show the dust collection unit 22 (the first electric dust collector 22a and the second electric dust collector 22b), the drawing of the front shutter 13 is abbreviate|omitted.

As shown in FIGS. 3, 4, and 6, the deodorizing unit 23 has a deodorizing filter 23a and a heating portion (heating means) 23f. As shown in Fig. 6, the deodorizing filter 23a includes a substrate 23aa having a disk shape, for example, having a porous structure such as a wavy structure or a honeycomb structure. The undulating structure has, for example, a flat material that is alternately laminated and a curved material that is continuously curved into a wave shape. A catalyst layer (deodorizing layer) 23ab that adsorbs and decomposes the odor component is provided on the substrate 23aa.

Further, the catalyst layer (deodorizing layer) 23ab may be a deodorizing layer which decomposes and/or adsorbs an odor component. Further, the deodorizing filter 23a has a circular plate shape and is rotatable. For example, the deodorizing filter 23a is rotatably supported on the main body portion 11 (or the casing).

As shown in FIGS. 3 and 4, the heating portion 23f includes a PTC (positive temperature coefficient) heater 23b and two dispersions. The hot plate 23c, the two heat insulating members 23d, and the two outer casings 23e. The PTC heater 23b is attached to the heat dissipation plate 23c disposed on the front surface side of the main body portion of the two heat dissipation plates 23c, and heats the two heat dissipation plates 23c. The two heat radiating plates 23c are metal plates each having a substantially triangular shape. As shown in FIGS. 4 and 6, the heat radiating plate 23c is disposed so as to cover only a part of the deodorizing filter 23a. The two heat radiating plates 23c are in contact with each other in the vicinity of the central portion of the deodorizing filter 23a or the outer diameter side of the deodorizing filter 23a. Therefore, the PTC heater 23b not only heats the heat radiating plate 23c disposed on the front side of the main body, The heat radiating plate 23c on the back side of the main body is also heated. The heat insulating member 23d is disposed to cover the PTC heater 23b and the heat radiating plate 23c. The heat insulating member 23d suppresses heat from escaping from the PTC heater 23b and the heat radiating plate 23c to the outside. The outer casing 23e has a shape capable of holding the PTC heater 23b, the heat radiating plate 23c, and the heat insulating member 23d.

Thereby, the deodorizing filter 23a has a porous structure, and the heating portion 23f has a structure that covers only a part of the deodorizing filter 23a. That is, the deodorizing filter 23a is disposed such that a part thereof is exposed to the ventilation passage 10. Therefore, the air resistance of the deodorizing filter 23a is small.

When the deodorizing ability of the deodorizing filter 23a is regenerated, a part of the deodorizing filter 23a covered by the two heat radiating plates 23c is heated by heating the two heat radiating plates 23c by the PTC heater 23b. The deodorizing filter 23a is heated while rotating the deodorizing filter 23a by a motor (not shown) to promote decomposition of the odor component adsorbed on the catalyst layer 23ab of the deodorizing filter 23a. Thereby, the deodorizing ability of the deodorizing filter 23a is regenerated. Alternatively, instead of rotating the deodorizing filter 23a, by dispersing The hot plate 23c is moved to heat the deodorizing filter 23a.

Further, the deodorizing unit 23 may not have the above-described configuration. The deodorizing unit 23 may not be provided with a heating device (the PTC heater 23b and the heat radiating plate 23c). In this case, the deodorizing filter of the deodorizing unit 23 includes an adsorbing material of an odor component such as activated carbon instead of the catalyst layer, and a substrate to which the adsorbent is added. In this case, when the adsorption capacity of the deodorizing unit 23 is lowered, the deodorizing ability of the deodorizing unit 23 can be restored by replacing the deodorizing filter with a new deodorizing filter.

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 humidifying filter 24a is rotatably supported by the rotating shaft in a state where a part thereof is immersed in water stored in the water storage container 24b. The humidification filter 24a sucks up moisture by rotating it by a motor (not shown).

Further, the humidifying unit 24 may not have the above-described configuration. The humidifying unit 24 may be provided with a humidifying filter that sucks water up by capillary action instead of the humidifying filter 24a. In addition, in FIG. 6, in order to clearly show the deodorizing means 23 and the humidifying unit 24, the drawing of the member which comprises the main-body part 11 other than the front-surface-

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. The fan motor 25b is configured to be air suctioned than the turbo fan 25a Entrance side (upstream side). By the rotation of the fan motor 25b, the turbo fan 25a also rotates. With the rotation of the turbo fan 25a, air flows into the inside of the air cleaner 1, and air flows out from the inside of the air cleaner 1. In addition, in FIG. 7, in order to clearly show the fan 25, the member which comprises the main body part 11 other than the front baffle 13, and the bottom part 11 d, the dust collection unit 22, the deodorizing unit 23, the humidification unit 24, etc Depiction.

Next, the operation of the air cleaner 1 during operation of the air cleaner 1 having the above configuration and the flow of air in the room in which the air cleaner 1 is installed will be described with reference to Fig. 8 . In the example shown in the figure, as shown in (B) of FIG. 8, the air cleaner 1 is installed in the room 300. The room 300 includes a ceiling surface 300a, a floor surface 300b, and four side wall surfaces 300c. The rear panel 14 of the air cleaner 1 is disposed adjacent to one surface of the side wall surface 300c so as to face the surface. When the user starts the operation of the air cleaner 1 by operating the operation unit 15, the fan 25 is driven, and the first electric dust collector 22a and the second electric dust collector 22b of the dust collection unit 22 are started to be energized. Further, the humidification filter 24a of the humidification unit 24 starts to rotate. When the fan 25 is driven, as shown by the broken line arrow 100 shown in FIG. 8(A), air is taken from the upper direction of the upper suction port 13a, the right side suction port 13b, the left side suction port 13c, and the bottom surface suction port 13d. The suction port is sucked into the inside of the main body portion 11.

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

(1) In the portion of the ventilation passage 10 where the lower portion of the deodorizing unit 23 and the upper portion of the humidifying unit 24 are overlapped in the front-rear direction, the air is pressed by the prefilter 21 → the dust collecting unit 22 → the deodorizing unit 23 → humidifying Sequence flow of unit 24 move.

(2) In the ventilating passage 10, in the portion where the lower portion of the deodorizing unit 23 and the upper portion of the humidifying unit 24 are not overlapped in the front-rear direction, the air is in the order of the prefilter 21 → the dust collecting unit 22 → the deodorizing unit 23. Or flowing in the order of the prefilter 21 → the dust collecting unit 22 → the humidifying unit 24.

At this time, the prefilter 21 and the energized dust collecting unit 22 remove dust and pollen contained in the inhaled air. Further, the deodorizing unit 23 removes the odor component contained in the inhaled air. Further, the humidifying unit 24 humidifies the inhaled air.

As shown by the solid arrow 200 shown in FIG. 8(A), the air after the dust removal, deodorization, and humidification in the air passage 10 is from the upper air outlet 14a, the right side air outlet 14b, and the left side air outlet 14c. The air outlets in these three directions are blown out into the room in which the air cleaner 1 is installed. At this time, as shown by the same solid arrow 200 shown in FIG. 8(B), the air blown from each air outlet is directed toward and disposed with the air cleaner 1 along the ceiling surface 300a or the side wall surface 300c of the room 300. The side of the side wall surface 300c on the opposite side of the side wall surface 300c flows, that is, the inside of the room 300 when viewed from the air cleaner 1. Specifically, the air blown from the upper air outlet 14a flows toward the inner side of the room 300 along the ceiling surface 300a. The air blown from the right side air outlet 14b flows toward the inner side of the room 300 along the right side wall surface 300c. The air blown from the left side air outlet 14c flows toward the inner side of the room 300 along the left side wall surface 300c.

As described above, the purified and humidified air is blown in such a manner as to surround the room 300 in which the air cleaner 1 is installed. In addition, the rear panel 14 and side walls The air cleaner 1 in which the surface 300c is opposed to the surface is sucked into the air of the room 300 from the suction ports of the upper suction port 13a, the right side suction port 13b, the left side suction port 13c, and the bottom surface suction port 13d. Therefore, the air cleaner 1 can improve the air flow of the room 300. As a result, the air cleaner 1 can inhale the air of the room 300 without any omission and dedust, humidify, and deodorize the inhaled air. Further, the air cleaner 1 can suck and disperse dust, pollen, odor components, and the like on the floor 300b together with the air taken in from the bottom surface suction port 13d. Thereby, the air cleaner 1 can improve the air circulation including the room 300 on the floor 300b. As a result, the air cleaner 1 can purify the air of the entire room 300 more efficiently.

A conventional air cleaner (dust removal device) is described in Japanese Laid-Open Patent Publication No. 2000-167326, for example. In the dust removing device described in this publication, air is sucked into the casing from the through hole of the front wall through the front filter unit. Therefore, in addition to the mesh provided on the back side of the front filter unit, a mesh is also provided in front of the front filter unit. Therefore, it is difficult to improve the design of the dust removing device.

In the air cleaner 1 of the present embodiment, the upper surface suction port 13a, the right side surface suction port 13b, the left side surface suction port 13c, and the bottom surface suction port 13d are provided around the space formed on the front side of the casing. Therefore, since the air suction port is not provided in the front flap 13 located in front of the casing, the design of the air cleaner 1 is improved.

That is, the present embodiment can provide an air cleaner 1 capable of circulating air in a room and having a high external appearance. Design.

Further, the air resistance of the dust collecting unit 22 is smaller than the air resistance of the dust collecting filter composed of the non-woven fabric formed into a pleated shape. Further, the heating portion 23f has a structure that covers only a part of the deodorizing filter 23a. That is, the deodorizing filter 23a is disposed such that a part thereof is exposed to the ventilation passage 10. Therefore, the air resistance of the deodorizing unit 23 is smaller than the air resistance of the conventional deodorizing unit having the plate-shaped heating portion formed in substantially the same area as the catalyst filter. Thereby, the turbo fan 25a having a lower static pressure than the sirocco fan can be used for the fan 25.

If the air resistance is the same, the air volume when the turbo fan 25a is used becomes smaller than when the sirocco fan is used. However, the turbo fan 25a has high efficiency and high quietness compared to the sirocco fan. Therefore, it is possible to realize the air cleaner 1 capable of ensuring the necessary dust collecting ability and deodorizing ability and suppressing noise.

Further, since the turbo fan 25a can be provided without a scroll housing provided by the sirocco fan, it can be made smaller and thinner than the sirocco fan. Therefore, the distance L to be described later can be secured, and the size of the casing of the air cleaner 1 can be suppressed from becoming excessive.

Further, in the air cleaner 1, the air resistance of the dust collecting unit 22 and the deodorizing unit 23 is small. Therefore, as shown in FIGS. 3 to 7, even when the dust collecting unit 22, the deodorizing unit 23, the humidifying unit 24, and the blower 25 are arranged in this order from the upstream side toward the downstream side of the air passage 10, the air cleaner 1 is Air resistance will not become too large. Therefore, the amount of air that flows through the ventilation passage 10 inside the main body portion 11 by the fan 25 does not decrease. In addition, By arranging and arranging the respective members as described above, 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 made large. Thereby, the occurrence of a short circuit between the so-called air intake port and the air blowing port, which is instantaneously sucked into the air cleaner 1 from the air intake ports, is suppressed. Further, as described above, the dust collecting unit 22 is disposed on the upstream side of the deodorizing unit 23. Therefore, the air that flows into the deodorizing unit 23 is air after dust, pollen, and the like are removed. Therefore, it is possible to prevent the deodorizing filter 23a of the deodorizing unit 23 from being blocked by dust, pollen or the like.

Further, as shown in FIGS. 3 and 4, in the fan (25), a fan motor (25b) and a turbo fan (25a) are disposed in order from the respective air intake ports toward the respective air outlets. In other words, the turbo fan 25a is disposed at a position farthest from each air intake port, and each air blowing port is disposed corresponding to the arrangement of the turbo fan 25a. Therefore, the distance L between each air suction port and each air blowing port can be increased. As a result, it is possible to obtain a higher effect of suppressing the occurrence of a short circuit. In addition, the arrangement order of the turbo fan 25a and the fan motor 25b may be reversed from that described above.

Further, a conventional air cleaner is disclosed in, for example, Japanese Laid-Open Patent Publication No. 2009-22882. In the air cleaner described in the publication, an air intake port is provided in the upper and lower spaces formed between the partition plate and the front baffle. Further, air blowing ports are provided on the left and right side surfaces of the main body casing. Therefore, in order to suppress the short circuit, only the air outlet can be placed in the cabinet. The two largest parts of the left and right sides. Therefore, the amount of air sent out from the cabinet of the air cleaner cannot be sufficiently ensured, and the air purifying ability may not be sufficiently exerted.

In the air cleaner described in Japanese Laid-Open Patent Publication No. 2009-22882, both end portions (upper and lower end portions) of the air outlets provided on the left and right side surfaces of the casing are disposed on the upper and lower sides of the casing. Near the air intake. Therefore, air sent from both end portions of the air blowing port may be immediately sucked into the inside of the casing from the air suction port. Therefore, in this prior art, it is difficult to sufficiently suppress the short circuit.

In response to this problem, in the air cleaner 1, it is possible to realize a distance L in which it is difficult to generate the short circuit. Therefore, the upper, lower, left, and right four gaps formed on the front side of the casing can be used as the upper suction port 13a, the right side suction port 13b, and the left side suction port 13c for taking in air to the inside of the air cleaner 1, respectively. And the bottom suction port 13d. Further, the upper, left, and right spaces formed on the back side of the casing can be used as the upper air outlet 14a, the right side air outlet 14b, and the left side air outlet 14c for blowing air from the inside of the air cleaner 1, respectively. Thereby, since the area of the air suction port and the air blowing port can be increased, the amount of air suction and the amount of blowing can be sufficiently ensured.

That is, as described above, in the present embodiment, it is possible to provide an air cleaner 1 capable of ensuring sufficient dust collecting ability and deodorizing ability, and capable of suppressing a short circuit more reliably.

Further, it is preferable that the height of the center of the fan motor 25b and the space between the first electric dust collector 22a and the second electric dust collector 22b of the dust collecting unit 22 are as shown in the line segment P of FIG. Highly consistent way, configuration set Dust unit 22 and fan 25. In the vicinity of the center of the fan motor 25b, the flow of air generated by the rotation of the turbo fan 25a is small. Therefore, it is considered that the flow of air in the space near the center of the fan motor 25b inside the main body portion 11 is small. On the other hand, in the space between the first electric dust collector 22a and the second electric dust collector 22b in the dust collecting unit 22, the dust collecting ability to the passing air is small. Therefore, by aligning the height of the space with the height of the center of the fan motor 25b, the first electric dust collector 22a and the second electric power can be disposed in a space in which the blades of the turbo fan 25a, which is considered to have a large flow of air, are located. Dust collector 22b. Thereby, the dust removal by the dust collection unit 22 can be performed efficiently.

Further, in the embodiment described above, the case where the air cleaner 1 has a casing having a substantially rectangular parallelepiped shape has been described as an example. However, the shape of the casing of the air cleaner 1 is not limited thereto, and may be a polyhedral shape having an upper side surface, a bottom surface, a left side surface, and a right side surface, and an air suction port or an air blowing port may be provided on each of the surfaces.

Further, in the present embodiment, the air cleaner 1 has both the deodorizing unit 23 and the humidifying unit 24. However, the present invention is not limited thereto, and the air cleaner 1 may have either one of the deodorizing unit 23 or the humidifying unit 24.
