However, in the conventional air treatment apparatus, since water is stored in the water container, bacteria may grow in this water and the water may be contaminated. Further, for example, when a substance such as ammonia (a harmful substance or an odorous substance) is contained in the air flowing through the air passage, the substance may be dissolved in water to contaminate the water in the water container. Therefore, when such contaminated water is supplied indoors as humidified water, the cleanliness of the room is impaired. Moreover, when draining such contaminated water suitably, the water pollution load of a drainage system (for example, a sewer) will become large.

Here, it may be possible to suppress the growth of bacteria by putting a disinfectant in the water container, but there is a possibility that a sufficient disinfecting action may not be obtained. In addition, an active species generating part is also provided on the water container side to generate active species such as radicals in the air or water, thereby sterilizing the active species in water or removing harmful substances dissolved in water. Although removal by oxidative decomposition can be considered, it is not preferable because it causes an increase in size and cost of the entire apparatus.

While supplying to (20), it is comprised so that the air containing the remaining active species may be supplied to the water in the said water container (41).

In the first invention, active species (radicals, ozone, fast electrons, excited molecules, etc.) are generated along with the discharge in the discharge processing section (25). A part of the air containing the generated active species is supplied to the air purification means (20), and the air containing the remaining active species is supplied to the water in the water container (41). Therefore, harmful substances contained in the air or water are decomposed and removed into active species and sterilized.

The air containing the active species that has been purified by the air purification means (20) and then transferred to the discharge processing section (25) through the return passage (15) is sent back to the air purification means (20) again. . Therefore, by circulating the active species by the air purification means (20), harmful substances in the air are reliably decomposed and removed by the active species and sterilized. Moreover, since the purified air is introduced into the discharge processing section (25), the discharge can be stabilized over a long period of time.

The second invention is an air purifying means (20) for purifying the air passing through the air passage (14), and a humidifying means for humidifying the air by applying water stored in the water container (41) to the air. (40) is assumed. The air treatment device includes a discharge processing unit (25) in which discharge is performed so as to generate active species, and the active species supplied from the discharge processing unit (25) to the water in the water container (41). And an active species return passage (36) for returning the active species to the upstream side of the discharge processing section (25), and the discharge processing section (25) removes a part of the generated active species from the air purification means ( 20), while the air containing the remaining active species is supplied to the water in the water container (41).

In the second invention, the active species generated in the discharge processing section (25) is supplied to the water in the water container (41), and the active species is supplied to the discharge processing section (25 via the active species return passage (36). ). Therefore, the active species are concentrated by repeatedly circulating air containing active species in the discharge processing section (25).

The third invention is an air purifying means (20) for purifying air passing through the air passage (14), and a humidifying means for humidifying the air by applying water stored in the water container (41) to the air. (40) is assumed. And this air treatment device comprises a discharge treatment section (25) where discharge is performed so as to generate active species, and air purified by the air purification means (20) upstream of the air purification means (20). A return passage (15) for returning to the air container, and a circulation passage (35) for circulating the air that has passed through the water container (41) to the air purification means (20), the discharge treatment section (25) Is arranged in the middle of the return passage (15) and is configured to supply air containing the generated active species to the water in the water container (41), and passes through the water container (41). The activated species are supplied to the air purification means (20) through the circulation passage (35).

In the third aspect of the invention, active species (radicals, ozone, fast electrons, excited molecules, etc.) are generated with the discharge in the discharge processing section (25). The air containing the generated active species is supplied to the water in the water container (41). Then, the active species that have passed through the water container (41) are supplied to the air purification means (20) via the circulation passage (35). Therefore, after harmful substances contained in water are decomposed and removed into active species and sterilized, harmful substances contained in the air are made active species by using the active species that have passed through the water container (41). It is decomposed and removed and sterilized.

According to a fourth aspect of the present invention, in any one of the first to third aspects, the first blower that supplies air containing active species from the discharge processing unit (25) to the air purification unit (20). Means (18) and second air blowing means (31) for supplying air containing active species from the discharge treatment section (25) into the water container (41). is there.

In 4th invention, while the air containing the active species produced | generated in the discharge process part (25) is supplied to the air purification means (20) by the 1st ventilation means (18), while the 2nd ventilation means (31) It is supplied into the water container (41). Therefore, the air containing the active species generated in the discharge treatment section (25) is reliably supplied into the air purification means (20) and the water container (41), and harmful substances contained in the air and water are activated species. It is decomposed and removed to be sterilized.

According to a fifth aspect of the present invention, in the fourth aspect of the invention, the control unit (17) includes a control unit (17) that controls the blowing operation of the first blowing unit (18) and the second blowing unit (31). The first air blowing means (18) and the second air blowing means (31) can be independently controlled for operation.

In the fifth invention, the air blowing operations of the first air blowing means (18) and the second air blowing means (31) are independently controlled by the controller (17). Therefore, the air blowing operation of the second air blowing means (31) can be performed even when the first air blowing means (18) is stopped. For this reason, even when air purification is not performed for a long period of time, it is possible to prevent bacteria from growing in the water in the water container (41) by operating the second air blowing means (31) independently.

The sixth invention is characterized in that, in the fourth or fifth invention, the second air blowing means (31) is disposed on the upstream side of the discharge processing section (25).

In the sixth invention, the second air blowing means (31) is disposed upstream of the discharge processing section (25). Therefore, the air containing the active species generated by the discharge processing unit (25) is not supplied to the second blowing means (31). For this reason, resin, rubber packing, etc. used for the ventilation pump etc. which comprise the 2nd ventilation means (31) do not corrode with the strong oxidizing power of active species .

In the present invention, a part of the air containing the active species generated in the discharge processing section (25) is supplied to the air purification means (20), and the air containing the remaining active species is supplied to the water in the water container (41). Therefore, it is possible to perform sterilization by decomposing and removing harmful substances contained in the air or water with active species.

That is, like conventional air treatment devices, air containing active species is supplied to the air purification means (20) to decompose and remove harmful substances, and a disinfectant is placed in the water container (41). In the configuration in which the propagation of harmful substances and the like is suppressed, the propagation of harmful substances in water may not be sufficiently suppressed. However, as in the present invention, the active species generated in the discharge treatment section (25) If the air containing water is supplied to the air purification means (20) and the water container (41), harmful substances in the water are reliably decomposed and removed by the active species, and the water can be purified. As a result, the water in the water container (41) can be purified more efficiently, and the purity of the water applied to the air can be maintained by sending the purified water to the humidifying means (40).

Therefore, for example, it can be avoided that contaminated water is supplied indoors and the cleanliness of the room is impaired, and the reliability of the air treatment device (10) can be ensured. For example, even if this water is discharged out of the system (sewer), the water pollution load outside the system can be surely reduced.

Furthermore, since the air containing the active species is supplied to the air purification means (20) and the water container (41) using one discharge processing section (25), the apparatus configuration can be simplified and the entire apparatus can be saved. This is advantageous in reducing costs by reducing the number of parts and the number of parts.

Further, after being purified by the air purification means (20), it is transferred to the discharge treatment section (25) through the return passage (15) and the air containing the active species is sent back to the air purification means (20) again. Therefore, by circulating the active species with the air purification means (20), harmful substances in the air can be reliably decomposed and removed by the active species. Moreover, since the purified air is introduced into the discharge processing section (25), the discharge can be stabilized over a long period of time.

In the second invention, the active species generated in the discharge processing section (25) is supplied to the water in the water container (41), and the active species is supplied to the discharge processing section via the active species return passage (36). Since the air is returned to (25), air containing active species is repeatedly circulated in the discharge processing section (25), and the active species can be concentrated to improve the sterilizing power of water. In other words, the concentration of active species can be increased using a small, low-power discharge processing unit (25) without increasing the concentration of active species by increasing the size of the discharge processing unit (25) or increasing the power. A sufficient sterilizing effect can be obtained while saving space and increasing the cost of the entire apparatus.

Moreover, in 3rd invention, the air containing the active seed | species produced | generated in the discharge process part (25) is supplied in a water container (41), and the active seed | species which passed the inside of a water container (41) is circulated through a circulation path (35). Since the harmful substances contained in the water are decomposed and removed into active species and sterilized by using the active species that have passed through the water container (41) Since harmful substances contained in the air are decomposed and removed into active species and sterilized, the active species can be efficiently circulated to purify air and water by using only one discharge treatment section (25). Can do.

Further, after being purified by the air purification means (20), the air containing the active species transferred to the discharge treatment section (25) through the return passage (15) is sent back to the air purification means (20) again. Therefore, by circulating the active species with the air purification means (20), harmful substances in the air can be reliably decomposed and removed by the active species. Moreover, since the purified air is introduced into the discharge processing section (25), the discharge can be stabilized over a long period of time.

In the fourth invention, the air containing the active species generated in the discharge processing section (25) is supplied to the air purification means (20) by the first blowing means (18), while the second blowing means (31). The air containing the active species generated in the discharge treatment section (25) is reliably supplied into the air purification means (20) and the water container (41), and the air is supplied to the water container (41). Hazardous substances contained in the inside and water are reliably decomposed and removed by the active species, and the air and water can be purified.

In the fifth aspect of the invention, since the controller (17) controls the air blowing operations of the first air blowing means (18) and the second air blowing means (31) independently, the first air blowing means (18 ) Can be blown by the second blowing means (31). For this reason, even when air purification is not performed for a long period of time, it is possible to prevent bacteria from growing in the water in the water container (41) by operating the second air blowing means (31) independently.

In the sixth aspect of the invention, since the second air blowing means (31) is disposed on the upstream side of the discharge processing section (25), the air containing the active species generated by the discharge processing section (25) is the second air blowing. It is not supplied to the means (31). For this reason, the resin and rubber packing used in the blower pump and the like forming the second blower means (31) do not corrode with the strong oxidizing power of the active species, and the corrosion resistance as a material of the resin or rubber packing There is no need to select a certain material, which is advantageous in reducing costs .

An inflow end of the return passage (15) is opened above the centrifugal fan (18) and below the outlet (13). That is, a part of the air flowing out from the air passage (14) to the blowout port (13) is divided into the return passage (15). The return passage (15) constitutes a space extending forward and backward so as to be partitioned from the air passage (14). The outflow end of the return passage (15) is connected to the upstream side of the prefilter (21). Further, a discharge processing section (25) is provided in the middle of the return passage (15).

As shown in FIG. 4, a guide passage (16) communicating with the return passage (15) is formed on the front side of the prefilter (21).

The guide passage (16) guides the air that has flowed out of the return passage (15) to the intermediate portion in the width direction of the prefilter (21), and flows this air to the left and right sides to send it to the prefilter (21) side. (See the arrow in FIG. 4).

Here, the return passage (15) is branched on the downstream side of the discharge processing section (25), one of which communicates with the guide passage (16), and the other is the water tank (41) of the humidifying unit (40). ) Communicates with the transfer pipe (30) toward In the middle of the passage of the transfer pipe (30), a blower pump (31) (second blower means) for supplying air containing active species generated in the discharge treatment section (25) to the water in the water tank (41) ) Is provided.

Here, the centrifugal fan (18) and the blower pump (31) are configured such that the blowing operation can be independently controlled by the control unit (17) provided in the casing (11). Thereby, even in a state where the centrifugal fan (18) is stopped, the blowing operation of the blowing pump (31) can be performed. For this reason, even when air purification is not performed for a long period of time, it is possible to prevent bacteria from growing in the water in the water tank (41) by operating the blower pump (31) independently.

As described above, in the air treatment device (10) of the present embodiment, a part of the air on the outflow side of the air passage (14) is supplied to the inflow side of the air passage (14) and the water tank through the discharge treatment section (25).

The pre-filter (21) constitutes a dust collecting filter that physically captures relatively large dust contained in the air.

The ionization part (22) constitutes a dust charging means for charging dust in the air. The ionization part (22) is provided with, for example, a linear electrode and a plate-like electrode facing the linear electrode. In the ionization part (22), a voltage is applied to both electrodes from a power source, so that corona discharge is performed between both electrodes. By this corona discharge, dust in the air is charged to a predetermined charge (positive or negative charge).

The pleated filter (23) constitutes a corrugated electrostatic filter. That is, in the pleated filter (23), the dust charged by the ionization part (22) is electrically attracted and captured. Note that a deodorizing material such as a photocatalyst may be supported on the pleated filter (23).

The deodorizing member (24) is configured such that a deodorizing agent for deodorizing air is carried on the surface of a substrate having a honeycomb structure. As the deodorizer, an adsorbent that adsorbs components to be treated (odorous substances and harmful substances) in the air, a catalyst for oxidizing and decomposing the components to be treated, and the like are used.

<Composition of humidification unit>

A humidification rotor (43) for applying water to the air and a drive motor (44) for rotationally driving the humidification rotor (43) are provided.

The water tank (41) constitutes a horizontally long water container whose upper side is open. The water tank (41) is installed in a lower space in the casing (11), and is configured to be freely taken in and out through an outlet (11b) of the casing (11) (see FIG. 1). Thereby, the user etc. can replenish the water tank (41) with the water for humidification suitably. Further, a bearing member (41a) for rotatably holding the water wheel (42) is erected on the bottom surface of the water tank (41).

The water turbine (42) is formed in a substantially disk shape that is flat in the front-rear direction, and a rotating shaft (42a) projects from the axial center. The rotating shaft (42a) is pivotally supported on the upper end of the bearing member (41a). The water wheel (42) is rotatably provided so that a part (predetermined part including the lower end portion) of the water tank (41) is immersed in the humidified water, and constitutes a rotating member.

The water wheel (42) is formed with a plurality of rear recesses (42b) around the axis of the rear side surface (side surface facing the humidification rotor (43)). The rear concave portion (42b) constitutes a humidifying concave portion for pumping humidified water toward the humidifying rotor (43). The plurality of rear recesses (42b) have a substantially trapezoidal opening whose width is increased toward the radially outer side. The circumferential width of the opening of the rear recess (42b) is narrower than the circumferential width of the internal space of the rear recess (42b). Furthermore, the inner wall on the radially inner side of the rear concave portion (42b) is inclined so as to gradually approach the axial center side toward the opening end. The rear recesses (42b) are arranged at equal intervals in the circumferential direction at the radially outer end of the water turbine (42). In the water wheel (42) during the rotating operation, the position where the rear concave portion (42b) is immersed in the water of the water tank (41) and the position where the water tank (41) is drawn out are alternately displaced.

Further, a gear (42c) is integrally formed on the rear side surface of the water turbine (42) at a portion near the axial center. The gear (42c) is configured to mesh with a driven gear (43a) of a humidifying rotor (43) described later.

The humidification rotor (43) has an annular driven gear (43a) and a disk-shaped moisture absorbing member (43b) that is fitted and held in the driven gear (43a). The hygroscopic member (43b) is made of a non-woven fabric having water absorption. The humidification rotor (43) is rotatably held via a rotating shaft at a position higher than the water level when the water tank (41) is full. Moreover, the humidification rotor (43) is arrange | positioned so that the predetermined site | part containing the lower end may contact substantially with a water turbine (42). That is, the humidification rotor (43) has a portion that coincides with the rear recess (42b) of the water turbine (42) in the axial direction. Thereby, the humidification rotor (43) is configured such that the humidifying water (43b) can absorb the humidified water pumped up by the rear concave portion (42b) of the water wheel (42).

The drive motor (44) has a drive gear (44a). The drive gear (44a) meshes with the driven gear (43a) of the humidification rotor (43) via the pinion (45). That is, when the drive motor (44) rotationally drives the drive gear (44a), the pinion (45) and the driven gear (43a) rotate, and further the water wheel (42) that meshes with the driven gear (43a) rotates. .

<Configuration of purification unit>
The air treatment device (10) includes a purification unit for purifying air and humidified water. The purification unit includes the above-described discharge processing unit (25), and the discharge processing unit (25) performs streamer discharge to purify air and humidified water.

The discharge processing section (25) is provided with a rod-like or linear electrode (26) and a plate-like electrode (27). Both electrodes (26, 27) are arranged in parallel to each other. When voltage is applied to both electrodes (26, 27) from the power source, streamer discharge is generated from the tip of the rod-shaped electrode (26) toward the plate-shaped electrode (27). By this streamer discharge, active species (radicals, ozone, fast electrons, excited molecules, etc.) are generated in the air.

Part of the air containing the active species generated in the discharge treatment section (25) is supplied to the prefilter (21) disposed on the most upstream side of the air purification means (20) through the guide passage (16). Is done. Further, the air containing the remaining active species is supplied into the water tank (41) via the transfer pipe (30). And this active species reacts with the to-be-processed component in the air or water, and this to-be-processed component is oxidatively decomposed and removed.

In the discharge treatment section (25), the rod-shaped or linear electrode (26) is on the positive electrode side, and the flat electrode (27) is on the negative electrode (or ground electrode) side. In addition, it is preferable that a DC high voltage is supplied from the power source to the discharge processing unit (25), and so-called constant current control is performed so that the discharge current of the discharge processing unit (25) is constant. Is preferred.

-Driving action-
In the air treatment device (10) according to the present embodiment, air is purified by the various air purification means described above, and indoor humidification is simultaneously performed by the humidification unit (40).

Specifically, first, the humidification rotor (43) and the water wheel (42) are rotationally driven by the drive motor (44). Further, when the centrifugal fan (18) is operated, indoor air is introduced into the air passage (14) through the suction port (12). Further, a high voltage is applied from the power source to the electrodes (26, 27) of the discharge processing section (25). Further, a voltage is applied from the power source to the electrode of the ionization section (22).

As shown in FIG. 2, the air flowing into the air passage (14) passes through the prefilter (21), captures dust, and then passes through the ionization section (22). In the ionization part (22), corona discharge is performed between the electrodes, and dust in the air is charged. The air that has flowed out of the ionization section (22) passes through the pleated filter (23). In the pleated filter (23), the charged dust is electrically attracted and captured. The air that has flowed out of the pleated filter (23) passes through the deodorizing member (24). In the deodorizing member (24), the component to be treated contained in the air is adsorbed by the adsorbent or is oxidized and decomposed by the catalyst.

By the way, in the air passage (14), part of the air on the outlet side (positive pressure side) of the centrifugal fan (18) flows into the return passage (15). The air flowing through the return passage (15) is sent forward and flows through the discharge processing section (25). In the discharge processing section (25), streamer discharge is performed between the electrodes (26, 27) facing each other. As a result, in the discharge processing unit (25), the above-described active species are generated along with the streamer discharge. Part of the air containing the active species joins with air flowing upstream of the prefilter (21) through the return passage (15). Therefore, in the air passage (14), active species flow from the inflow end to the outflow end, and a reaction time between the component to be treated and the active species in the air is secured, thereby improving the deodorization performance.

On the other hand, the remaining air containing the active species flowing through the return passage (15) is supplied into the water tank (41) through the transfer pipe (30) branched in the middle of the passage. This active species is used for sterilization of humidified water by removing toxic substances contained in water by oxidative decomposition.

During the humidification operation, the air that has passed through the deodorizing member (24) flows into the humidification rotor (43). Here, in the humidification unit (40), the water turbine (42) rotates, so that the humidified water in the water tank (41) is appropriately supplied to the moisture absorbing member (43b) of the humidification rotor (43). Specifically, in the water wheel (42), the rear concave portion (42b) is immersed in the humidified water stored in the water tank (41). Thereby, in humidified water, humidified water penetrate | invades and is hold | maintained in a back side recessed part (42b). The rear concave portion (42b) in the state of holding the humidified water is pulled up from the humidified water and further displaced upward. When the rear recess (42b) gradually approaches the humidification rotor (43), the humidified water retained in the rear recess (42b) gradually flows out of the rear recess (42b) by its own weight. . When the rear concave portion (42b) is displaced to the uppermost position, substantially all of the humidified water in the rear concave portion (42b) flows out.

The humidified water flowing out from the rear concave portion (42b) comes into contact with the humidifying rotor (43) adjacent to the rear concave portion (42b) and is absorbed by the moisture absorbing member (43b). With such an operation, in the humidification unit (40), humidified water is continuously supplied to the humidification rotor (43).

In the humidification rotor (43), air circulates through the portion replenished with moisture. As a result, the humidified water contained in the moisture absorbing member (43b) is released into the air, whereby the air is humidified. The air purified and humidified as described above is supplied into the room through the air outlet (13).

In the humidification operation, it is also possible to perform an operation that does not actively purify air by stopping the supply of voltage from the power source to the ionization unit (22) and the discharge processing unit (25). In addition, while the humidifying operation of the humidifying unit (40) is substantially stopped, the discharge is performed by the ionization unit (22) and the discharge processing unit (25), thereby purifying the air without humidifying the air. It is also possible to perform an air cleaning operation.

As described above, according to the air treatment device (10) according to the present embodiment, a part of the air containing the active species generated by the discharge treatment unit (25) is supplied to the air purification means (20), and the rest Since the air containing the active species is supplied to the water in the water tank (41), toxic substances contained in the air or water can be decomposed and removed by the active species for sterilization. Therefore, for example, it can be avoided that contaminated water is supplied indoors and the cleanliness of the room is impaired, and the reliability of the air treatment device (10) can be ensured. For example, even if this water is discharged out of the system (sewer), the water pollution load outside the system can be surely reduced.

Further, since the air containing the active species is supplied to the air purification means (20) and the water tank (41) using one discharge processing section (25), the apparatus configuration can be simplified and the entire apparatus can be saved. This is advantageous in reducing costs by reducing the number of parts and the number of parts.

<Modification 1>
As shown in FIG. 6, a discharge processing section (25) is disposed between the ionization section (22) and the pleated filter (23) to supply active species to the air passing through the air passage (14). The active species may be supplied to the water tank (41) through the transfer pipe (30) communicated with the downstream side of the discharge processing section (25). With this configuration, air containing active species is directly supplied to the dust trapped by the pleated filter (23) to decompose and remove harmful substances and sterilize the water in the water tank (41). It can decompose and remove contained harmful substances.

As described above, since only air and water can be sterilized by using only one discharge processing section (25), the configuration of the apparatus can be simplified, and the cost of the entire apparatus can be saved and the number of parts can be reduced. This is advantageous for downing.

<Modification 2>
As shown in FIG. 7, the air taken in from the outside of the casing (11) is sent to the discharge treatment section (25), the air containing the active species is supplied into the water tank (41), and the inside of the water tank (41) is supplied. The active species that have passed may be circulated to the prefilter (21) through the circulation passage (35). With such a configuration, the active species generated in the discharge treatment section (25) are supplied to the water tank (41) to decompose and remove toxic substances contained in the water, and then the water tank ( 41) Since active substances that have passed through can be sterilized by decomposing and removing harmful substances contained in the air, air and water can be efficiently used with only one discharge treatment section (25). Purification can be performed.

<Modification 3>
As shown in FIG. 8, the air that has passed through the deodorizing member (24) is sent to the discharge treatment section (25) through the return passage (15), and the air containing the active species is supplied into the water tank (41). The active species that have passed through the water tank (41) may be circulated to the prefilter (21) through the circulation passage (35). With such a configuration, as in the second modification, the active species generated in the discharge treatment section (25) are supplied to the water tank (41) to decompose and remove toxic substances contained in the water for sterilization. After that, the active species that have passed through the water tank (41) are used to decompose and remove toxic substances contained in the air for sterilization. And water purification. In FIG. 8, the return passage (15) is connected to the upstream side of the centrifugal fan (18), but may be connected to the downstream side.

Furthermore, in the modification 3, as shown also in FIG. 9, the ventilation pump (31) is arrange | positioned in the upstream of a discharge process part (25). With such a configuration, since the air containing the active species generated in the discharge processing section (25) is not supplied to the blow pump (31) side, the resin used for the blow pump (31) And rubber packing are preferred because they are not corroded by the strong oxidizing power of active species.

In addition to disposing the blower pump (31) on the upstream side of the discharge processing unit (25), as shown in FIG. 10, the downstream end of the discharge processing unit (25) is connected to the downstream side of the blower pump (31). May be combined with the transfer pipe (30), mixed with air and active species in the transfer pipe (30), and then supplied to the water tank (41). With such a configuration, since the air containing the active species generated in the discharge processing section (25) is not supplied to the blow pump (31) side, the resin used for the blow pump (31) This is advantageous in terms of cost reduction, because the rubber packing and the like are not corroded by the strong oxidizing power of the active species, and it is not necessary to select a corrosion-resistant material as the material of the resin or rubber packing.

<Modification 4>
As shown in FIG. 11, an active species return passage (36) is provided for returning the active species supplied from the discharge treatment section (25) to the water in the water tank (41) to the upstream side of the discharge treatment section (25). It is good also as a composition. With such a configuration, air containing active species is repeatedly circulated in the discharge processing section (25), and the active species can be concentrated, thereby improving the sterilizing power of water. In other words, the concentration of active species can be increased using a small, low-power discharge processing unit (25) without increasing the concentration of active species by increasing the size of the discharge processing unit (25) or increasing the power. A sufficient sterilizing effect can be obtained while saving space and increasing the cost of the entire apparatus.

In the above-described embodiment and each modification, a blowing unit and a blowing pump for conveying air containing active species are illustrated. However, air pressure sufficient for conveyance can be obtained by optimizing the flow path and the like. In such a case, a configuration that does not use them may be used.

As described above, the present invention is extremely useful and industrial because it provides a highly practical effect that the water in the water container can be stably purified while reducing the space and cost of the entire apparatus. The above availability is high.
