These active species include fast electrons, ions, hydroxyl radicals, and excited oxygen molecules, and these active species are in the air consisting of small organic molecules such as ammonia, aldehydes, nitrogen oxides, etc. Decomposes harmful and odorous components.

The partition member 28 is a plate-like member that is disposed on the same plane as the right suction surface 20b of the blower fan 20, and is a member that partitions the space of the blower chamber 2 into the left space 2a and the right space 2b. Therefore, as shown in FIG. 3, the motor 22, the blower fan 20, the dust sensor 25, and the electrical member 26 are arranged in the left space 2 a on the left side of the blower chamber 2 when viewed from the front. The electrical component of the present invention includes a motor 22, a dust sensor 25, an electrical component member 26, and the like. A distance T1 from the left suction port 11a to the left suction surface 20a is longer than a distance T2 from the right suction port 12a to the right suction surface 20b. Further, the motor 22 and the water tank 53 are arranged apart from each other in the left-right direction.

In the air purifier 1, as shown by the dotted arrow in FIG. 3, a part of the air that has passed through the air purifying filter 30 is sent to the streamer discharge unit 27 as a tributary. When this tributary passes through the streamer discharge unit 27, the active species generated by the streamer discharge is supplied to the tributary. The tributary to which the active species is supplied merges with the air flow (main flow) indicated by the solid line arrow in FIG. 3 and is sent to the top air outlet 13a side.

As shown in FIG. 5, the air sent to the streamer discharge unit 27 as a branch flow passes through the duct 35 from the opening 34 of the filter cover 33 and passes through the duct 35 (specifically, the right suction port and the prefilter that covers the right suction port). And the streamer discharge unit 27 disposed inside the prefilter.

Fig.6 (a) is the schematic which shows the flow of the air of the ventilation chamber 2 of the air cleaner 1 of this invention, Comprising: FIG.6 (b) is the flow of the air of the ventilation chamber of the air cleaner of a comparative example. FIG. FIG. 6B is a diagram in which the partition member 28 is omitted from FIG. In the comparative example, as shown in FIG. 6B, the distance from the left suction port 11a to the left suction surface 20a is longer than the distance from the right suction port 12a to the right suction surface 20b. While much air is sucked into the blower chamber 2, the amount of air sucked into the blower chamber 2 from the left suction port 11a is small. The air sucked from the front suction port 10a is divided into the left suction surface 20a and the right suction surface 20b of the blower fan 20 and sucked. Therefore, the air sucked from the left suction surface 20a, a part of the air sucked from the front suction port 10a, and a part of the air sucked from the right suction port 12a are sucked into the left suction surface 20a of the blower fan 20. The air sucked from the right suction surface 20b and a part of the air sucked from the front suction port 10a are sucked into the right suction surface 20b. Thus, a part of the air sucked from the right suction port 12a circulates around the blower fan 20 and is sucked from the left suction surface 20a, so that the left suction surface 20a and the right suction surface 20b of the blower fan 20 are Approximately the same amount of air is inhaled. Therefore, in the comparative example, when the dust sensor is arranged on the left suction port 11a side where the amount of air sucked is small, there is a problem that the amount of dust cannot be properly detected by the dust sensor.

On the other hand, in the present invention, as shown in FIG. 6A, the distance T1 from the left suction port 11a to the left suction surface 20a is longer than the distance T2 from the right suction port 12a to the right suction surface 20b. Nevertheless, since the air blowing chamber 2 is partitioned into the left space 2a and the right space 2b by the partition member 28, the amount of air sucked into the air blowing chamber 2 from the left suction port 11a is increased as compared with the comparative example, The amount is slightly less than the amount of air sucked from the suction port 12a. The air sucked from the front suction port 10 a is sucked into the left suction surface 20 a of the blower fan 20. Therefore, a part of the air sucked from the left suction surface 20a and a part of the air sucked from the front suction port 10a are sucked into the left suction surface 20a of the blower fan 20, and the right suction surface 20b from the right suction surface 20b. Inhaled air is inhaled. In this way, a part of the air sucked from the right suction port 12a goes around the blower fan 20 and is not sucked from the left suction surface 20a, and the left suction surface 20a and the right suction surface 20b of the blower fan 20 are Approximately the same amount of air is inhaled. Therefore, in the present invention, the dust sensor 25 is disposed in the left space 2a. However, since the amount of air sucked from the left suction port 11a is larger than that of the comparative example, the dust sensor 25 can appropriately detect the amount of dust.

The electrical component of the present invention includes a motor 122, a dust sensor, an electrical component, and the like.

In the present embodiment, as shown in FIG. 8, since the blower chamber 102 is partitioned into a front side space 102 a and a back side space 102 b by a partition member 128, the air sucked from the front suction port 110 a is blown by the blower fan 120. The air sucked into the front suction surface 120a and sucked from the left suction port 111a, the right suction port 112a, and the rear suction port 113a is sucked into the rear suction surface 120b of the blower fan 120. Therefore, the amount of air sucked into the front side space 102a of the blower chamber 102 and the amount of air sucked into the back side space 102b are substantially equal. Therefore, in the present invention, the dust sensor is disposed in the back side space 102b, but the amount of dust can be appropriately detected by the dust sensor.

<Characteristics of the air cleaner of the present embodiment>
The air cleaner 101 of this embodiment has the following features.

In the air cleaner 101 of this embodiment, in the air blowing chamber 102, the front side space 102a through which air flowing from the front suction port 110a of the casing toward the front suction surface 120a of the blower fan 120 passes, and the left suction port 111a of the casing. Since the rear side space 102b through which the air flowing from the right suction port 112a and the rear suction port 113a toward the rear suction surface 120b of the blower fan 120 passes is partitioned, the air is sucked into the front side space 102a of the blower chamber 102. The amount of air and the amount of air sucked into the back side space 102b can be made substantially equal.

In this embodiment, the front suction port 110a of the casing is the first suction port of the present invention, and the left suction port 111a, the right suction port 112a, and the rear suction port 113a of the casing are the second suction ports of the present invention. The front suction surface 120a of the blower fan 120 is the first suction surface of the present invention, and the rear suction surface 120b of the blower fan 120 is the second suction surface of the present invention.

As mentioned above, although embodiment of this invention was described based on drawing, it should be thought that a specific structure is not limited to these embodiment. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and further includes meanings equivalent to the scope of claims for patent and all modifications within the scope.

In the above-described first embodiment, the case where the left space 2a and the right space 2b are completely partitioned in the blower chamber 2 has been described, but the left space 2a and the right space 2b are mostly partitioned. In this case, the effect of the present invention can be obtained. Therefore, for example, as illustrated in FIG. 9, an opening 28 a may be formed in a portion of the partition member 28 that is disposed below the blower fan 20. In this case, since air flows from the right space 2b to the left space 2a, a part of the air that has passed through the streamer discharge unit 27 can be prevented from accumulating at the lower end of the right space 2b.

In the first embodiment described above, the left and right ventilation resistances are different due to the difference in distance from the left suction port 11a to the left suction surface 20a and the distance from the right suction port 12a to the right suction surface 20b in front view. Although the case has been described, the distance from the left suction port 11a to the left suction surface 20a and the distance from the right suction port 12a to the right suction surface 20b may be the same, or the left suction surface 11a to the left suction surface 20a. And the distance from the right suction port 12a to the right suction surface 20b are the same and other configurations (for example, the size of the left suction port 11a and the right suction port 12a are different) The ventilation resistance may be different.

In the above-described first embodiment, the case where the casing 1a has the front suction port 10a disposed on the front surface thereof has been described. However, the casing 1a does not have the front suction port 10a disposed on the front surface thereof. It's okay.

In the first and second embodiments described above, the air cleaner has the air blowing chamber, the air cleaning chamber, and the humidifying chamber, and the humidifying function and the air cleaning function are described. It has a ventilation chamber and an air purifying chamber, and may have an air purifying function (without a humidifying function).

If the present invention is used, the amount of air sucked into the space on the first suction surface side and the space on the second suction surface side of the fan in the air blowing chamber can be made substantially equal.
