Hereinafter, an air cleaner having a humidifying function will be described as an example of a humidifier to which the present invention is applied. However, the present invention does not require an air cleaning function as an essential component, and can be applied to a humidifier without an air cleaning function.
(1) Overview of Air Purifier Configuration and Operation An overview of the overall configuration of an air purifier according to an embodiment of the present invention is shown in FIGS. FIG. 1 is a perspective view seen from the upper right side toward the front of the air cleaner, and FIG. 2 is a perspective view seen from the upper left side toward the back of the air cleaner.
The air cleaner 10 has a suction port 11 that takes in indoor air and a blower port 12 that blows out humidified air. The suction port 11 includes a front lower suction port 11a and a side suction port 11b.

FIG. 3 is a conceptual diagram for explaining the concept of dust removal and decomposition and humidification in an air cleaner. The sirocco fan 16 generates an air flow 13 from the inlet 11 to the outlet 12. Dust and odor components are removed from the indoor air sucked from the suction port 11 by the filter unit 14, and humidified by the humidifying unit 15, and clean air humidified from the sirocco fan 16 is blown out.
The filter unit 14 includes a pre-filter 17A, a HEPA (High Efficiency Particulate Air Filter) filter 17B, and a deodorizing element 17C. First, large dust is removed by the pre-filter 17A that the air cleaner 10 has. Next, finer dust is removed by the HEPA filter 17B. Further, the air that has passed through the HEPA filter 17B is decomposed or adsorbed by formaldehyde, odor components, and the like by the deodorizing element 17C containing activated carbon or the like.

The humidifying unit 15 includes a humidifying rotor 50, a water tray 40, and the like. The air that has passed through the deodorizing element 17 C passes through the humidification rotor 50 of the humidification unit 15. When air passes through the humidification rotor 50, moisture is released from the humidification rotor 50 into the air. The humidification rotor 50 receives water from the water tray 40 in order to compensate for moisture that is reduced by being discharged.
A diversion stream 13 a blown from the sirocco fan 16 is sent to the streamer discharge unit 18. When the air flow 13a passes through the streamer discharge unit 18, active species are supplied by the streamer discharge. A part of the divided stream 13b to which the active species is supplied is divided into a plurality of divided streams 13c and is blown out from the small openings to the front of the prefilter 17A. The plurality of branch streams 13c join the room air sucked from the prefilter 17A and reach the deodorizing element 17C. The deodorizing effect is enhanced by the active species reaching the deodorizing element 17C.

The branch stream 13d separated from the branch stream 13b and the branch stream 13c is sent to the upper space Sp1 of the water in the water tray 40. Due to the active species of the diversion flow 13c, the propagation of bacteria in the water tray 40, the occurrence of slime, and the like are suppressed, and the inside of the water tray 40 is kept clean.
Switching of the operation of the air cleaner 10 having such a humidifying function is performed by an operation panel 19 provided on the upper portion of the air cleaner 10. The operation panel 19 is provided with a switch for operating on / off of the humidifying operation in addition to on / off of the operation of the air purifier 10. Thereby, an operation mode in which only air cleaning is performed without humidification and an operation mode in which humidification is performed simultaneously with air cleaning are prepared.
In the operation mode in which only air cleaning is performed, the rotation of the humidification rotor 50 is stopped, and water is not supplied to the humidification rotor 50. Therefore, after the humidification rotor 50 is dried, the release of water into the air stops.

(2) Detailed Configuration (2-1) Water Tank As shown in FIG. 4, a water tank 30 is accommodated on the left side of the air cleaner 10. The outer casing of the air cleaner 10 is covered with a main body casing 20. The main body casing 20 is configured such that the left side plate 21 can be removed, and a water tank 30 is attached to the left side plate 21. Although not shown, a water inlet is provided below the water tank 30.
In the main body casing 20, a lower left side plate 22 that is curved so as to squeeze the lower side of the air cleaner 10 is disposed below the left side plate 21. This lower left side plate 22 is attached to the water tray 40. When the water tank 30 is attached, the water in the water tank 30 is poured into the water tray 40 from the water inlet below the water tank 30.

A fan casing 70 in which the sirocco fan 16 shown in FIG. 3 is housed is disposed on the right side of the water tank 30 in the main body casing 20. The fan casing 70 extends upward toward the air outlet 12, and the air outlet of the fan casing 70 coincides with the air outlet 12 of the main body casing 20.
(2-2) Water Tray The state shown in FIG. 5 is a state where the left side plate 21, the water tank 30 and the water tray 40 are removed from the state shown in FIG. 4, and the sirocco fan is removed together with the fan casing 70. The water tray 40 is mounted from the external space Sp1 shown in FIG. In FIG. 5, a member on the front side having a honeycomb-shaped opening is a filter support member 80. The pre-filter 17A, the HEPA filter 17B, and the deodorizing element 17C shown in FIG. 3 are attached to the filter support member 80.

The filter support member 80 is provided with a delivery port 81 facing the space above the water tray 40 in the space Sp1. Air containing active species is blown out from the outlet 81.
6 and 7 show a state in which the main body casing 20, the water tank 30, and the filter support member 80 excluding the lower left side plate 22 are removed from the state of FIG. 6 is a perspective view of the air purifier 10 as viewed from the upper left side of the air cleaner 10, and FIG. 7 is a perspective view of the air purifier 10 as viewed from the upper left side of the air cleaner 10.
The water tray 40 mainly includes a water receiving portion 41 disposed under the water tank 30, a rotor immersion portion 42 in which a lower portion of the humidifying rotor 50 is immersed in water, a partition wall 43, a bearing 44, a partition And a plate 45. The bearing 44 that receives the shaft of the humidifying rotor 50 is attached on the side wall of the water tray 40 that constitutes the rotor immersion portion 42.

The water receiving part 41 and the rotor immersion part 42 are partitioned by a partition wall 43 that partitions the water stored in the water tray 40. The partition wall 43 is provided with an opening from the water receiving portion 41 to the rotor immersion portion 42 in a lower portion hidden by the lower left side plate 22 in FIG. Thereby, the opening is closed with water while water is in the water tray 40, and the water receiving part 41 and the rotor immersion part 42 are separated.
The partition plate 45 extends upward from above the partition wall 43 without a gap. In a state where the water tray 40 is mounted, the partition plate 45 is fitted to the fan casing 70 without a gap. Then, the water tray 40 is locked to the fan casing 70 by the lock mechanism in the state shown in FIG.
A space Sp 2 in which the humidification rotor 50 is accommodated is a space inside the housing formed by the fan casing 70 and the filter support member 80. The space Sp 2 is surrounded by the side wall 71, the upper wall 72, the lower wall 73, the rear wall 74, the partition plate 45, and the filter support member 80. Thereby, the space Sp2 is partitioned from the external space Sp1, and the path connecting the external space Sp1 and the space Sp2 is limited to a specific path such as the suction port 11 or the air outlet 12. This housing has no openings other than the honeycomb-shaped openings formed in the filter support member 80 and the openings provided in the rear wall 74. Therefore, the same amount of air as the air supplied from the filter support member 80 to the space Sp 2 passes through the rear wall 74 from the space Sp 2 and is supplied to the sirocco fan 16.

A part of the air blown upward from the sirocco fan 16 becomes a divided flow 13a and is sent from the opening 79 of the fan casing 70 toward the streamer discharge unit 18. The flow path through which the diversion flow 13 a passes is surrounded by the main body casing 20 and the fan casing 70, and does not communicate except for the opening 79 and the streamer discharge unit 18. For this reason, air does not flow in from the external space, and the divided flow 13a does not flow out to the external space. The diversion flow 13b to which the active species is applied by the streamer discharge unit 18 is blown out from the streamer discharge unit 18 toward the lower water tray 40.
FIG. 8 is a diagram showing a configuration of a part in which a water receiving part 41, a rotor immersion part 42, and a partition wall 43 of a water tray are integrally formed. FIG. 8A is a plan view of this part, FIG. 8B is a front view of this part, and FIG. 8C is a side view of the partition wall.

Screws for fastening the partition plate 45 are screwed into the two screw holes 40 a in the vicinity of the water receiving portion 41 and the partition wall 43. In addition, screws for fastening the bearings 44 are screwed into the screw holes 40b and 40c provided in the front side wall 42a and the rear side wall 42b of the rotor immersion part 42, respectively.
As can be seen from FIG. 8B, the partition 40 d protrudes below the water tray 40. The partition portion 40d extends long in the front-rear direction below the water tray 40. The partition portion 40d hits the lower wall 73 of the housing below the water tray 40 to partition the housing space Sp2 and its external space.
As shown in FIG. 8C, the partition wall 43 is provided with an opening 43a, and the water receiving part 41 and the rotor immersion part 42 are connected by the opening 43a. Therefore, the water supplied from the water tank 30 to the water receiving part 41 flows into the rotor immersion part 42 through the opening 43a. The water level when water remains in the water tank 30 is indicated by a two-dot chain line 43b. If there is a water level up to this height, the opening 43a is blocked by water, so the opening 43a does not serve as an air bypass path.

(2-3) Humidification Rotor A humidification rotor 50 shown in FIG. 6 has a structure in which a porous vaporization filter 51 is attached to a ring-shaped frame 52. The humidification rotor 50 performs humidification by vaporizing water from the vaporization filter 51. Therefore, it is designed so that the lower part of the dry vaporization filter 51 is immersed in the water of the rotor immersion part 42 as the humidification rotor 50 rotates. Further, in order to assist water supply to the vaporization filter 51, water is pumped up by the water reservoir 53, and the inner periphery of the ring frame 52 is vaporized from the water reservoir 53 through a hole (not shown) of the ring frame 52. The filter 51 is configured to be able to supply water. Although not shown, the humidification rotor 50 is rotated by a motor.
(2-4) Sirocco Fan and Fan Casing FIG. 9 shows a state where the humidification rotor 50 and the bearing 44 are removed from the state shown in FIG. By removing the humidification rotor 50, the sirocco fan 16 on the downstream side of the humidification rotor 50 can be seen. Humidified air is supplied to the sirocco fan 16 from the opening 76 of the rear wall 74 of the housing.

(3) Flow path for supplying active species A flow path for flowing the diversion flows 13a, 13b, 13c, and 13d shown in FIG. 3 will be described with reference to the drawings. FIGS. 10 and 11 are a perspective view and a front view of the air cleaner 10 in a state where the front lid 23 of the main body casing 20 shown in FIG. 1 is removed. FIG. 12 shows a cross section taken along the line II of FIG. In addition, what was shown with the dotted line in FIG. 12 is the mesh part of the pre-filter 17A. 13 and 14 are views for explaining the configuration of the filter support member. 13A is a front view of the filter support member, FIG. 13B is a rear view of the filter support member, and FIG. 13C is a side view of the filter support member.
The flow path through which the divided flow 13a flows has already been described with reference to FIG. The flow path through which the divided flow 13 a flows is a flow path that leads from the opening 79 of the fan casing 70 to the streamer discharge unit 18, and is surrounded by the main body casing 20 and the fan casing 70.

As shown in FIG. 7, the diversion flow 13 b supplied with the active species by the streamer discharge unit 18 is blown downward from the streamer discharge unit 18. As shown in FIGS. 13A and 13B, the streamer discharge unit 18 is provided in the upper left part of the filter support member 80 for storing the streamer discharge unit 18 that penetrates from the back side to the front side. A storage portion 82 is formed. A hollow portion extends downward from the storage portion 82 to form a flow path 83. The hollow part which comprises the flow path 83 is formed by fitting the front side part 80a and the back side part 80b which comprise the filter support member 80 so that FIG. 12 may show.
The channel 83 is formed with a large number of apertures 84 arranged in the vertical direction. The opening 84 is formed along the side suction port 11b. Therefore, the branch flow 13c blown from the opening 84 is a flow toward the prefilter 17A.

A delivery port 81 is formed below the flow path 83. As shown in FIG. 5, the delivery port 81 is located above the upper end of the lower left side plate 22, that is, located in the space above the water tray 40. The position of the delivery port 81 is above the water receiving part 41 of the water tray 40. From this outlet 81, active species can be sent into this water receiving part 41 to suppress the growth of bacteria in the water receiving part 41 and to suppress the occurrence of sliminess. And when the water level of the water receiving part 41 is low, active species are sent to the rotor immersion part 42 through the opening part 43a shown in FIG.
(4) Features (4-1)
As shown in FIG. 3, part of the air blown out by the sirocco fan 16 from the opening 79 of the fan casing 70 becomes a diversion 13 a, and finally, the outlet in the upper space of the water tray 40. 81 is blown out. No particular fan or the like is provided during this period, and the air is blown out only by the wind pressure of the sirocco fan 16. Therefore, it is generated by streamer discharge (plasma discharge) in the streamer discharge unit 18 (discharge section) in the space above the water in the water tray 40 by a simple mechanism such as a flow path 83 such as a flow path (flow path). Activated species can be sent. Thereby, the water receiving part 41 of the water tray 40 can be kept clean. Further, in a situation where the active level can be sent to the rotor immersion part 42 through the opening 43a of the partition wall 43 by lowering the water level, the rotor immersion part 42 can also be kept clean by the active species.

As described with reference to FIG. 9 and the like, the sirocco fan 16 is disposed on the downstream side of the humidifying unit 15 including the water tray 40 and the humidifying rotor 50. The streamer discharge unit 18 (discharge section) is provided between the opening 79 of the fan casing 70 and the flow path 83 of the filter support member 80, and is disposed on the downstream side of the sirocco fan 16. The water tray 40 in the vicinity of the outlet 81 of the flow path 83 is disposed on the downstream side of the streamer discharge unit 18 in the flow path. In this way, a flow path that creates a flow of active species air to the upper space of the water tray 40 only by blowing out the sirocco fan 16 is realized with a simple configuration.
