Detailed Description

The present invention first provides a control method of an air treatment device, fig. 1 is a schematic configuration diagram of an air treatment device according to an embodiment of the present invention, and fig. 2 is a schematic sectional view of an air treatment device according to an embodiment of the present invention.

Referring to fig. 1 and 2, the air treatment device 1 of the present invention includes a housing 10. The housing 10 is provided with an air inlet and an air outlet 13. The air outlet 13 is used for communicating with the indoor. In a specific embodiment, the number of the air inlets can be one, and the air inlets can be communicated with the indoor space or the outdoor space. In another specific embodiment, the number of the air intakes may also be two or more, for example, in the embodiment shown in fig. 1, the number of the air intakes is two, and it includes an indoor air intake 11 for communicating with the indoor space and an outdoor air intake 12 for communicating with the outdoor space to introduce fresh air. The indoor air inlet 11 and/or the outdoor air inlet 12 can be selectively opened or closed by a damper, so as to selectively allow indoor return air and/or outdoor fresh air to enter the air processing device 1, and the air is processed by the air processing device 1 and then sent out.

It should be noted that the indoor space in the embodiment of the present invention means an indoor environment space where the air processing device 1 is located, and the outdoor space in the embodiment of the present invention means an outdoor environment space.

An air duct communicating the air inlet and the air outlet 13 is formed in the housing 10, and a fan 21 for driving air flow to flow from the air inlet to the air outlet 13, a water storage tank 31 for containing water, and a drum-type washing device are arranged in the air duct.

The drum type water washing device includes a drum 41 rotatably disposed in the water storage tank 31, and an upper section of the drum 41 is in an airflow flow path in the air duct to take out water in the water storage tank 31 by rotation of the drum 41 and wash the airflow with water taken out on the drum 41 for purification and/or humidification as the airflow passes through the drum 41.

Specifically, when cylinder 41 rotated, can take out the water in the storage water tank 31, can contact with the water that takes out on the cylinder 41 when the air current flows through cylinder 41, on the one hand, solid pollutants such as particulate matter, batting in the air current and water-soluble harmful gas all can remain the aquatic, and on the other hand, the air current still can carry away partial aqueous vapor after contacting with water to the mesh of washing purification and humidification has been realized to the air current. This application utilizes water and the air current contact of carrying on the cylinder 41 to cylinder 41 is pivoted, compares the water curtain that forms among the prior art, and the mode of this application water and air current contact can not produce great resistance to the air current, has reduced the influence to the air current velocity of flow.

FIG. 3 is a schematic exploded view of a portion of an air treatment device according to one embodiment of the present invention. In some embodiments, the drum-type washing device further includes a driving mechanism 42 for driving the drum 41 to rotate. The drive mechanism 42 may include a motor 421 and a gear assembly 422. The motor 421 is provided on the housing 10 for outputting a driving force. The gear assembly 422 is connected between the motor 421 and the rotating shaft 411 of the drum 41, for transmitting the driving force output from the motor 421 to the rotating shaft 411, thereby causing the drum 41 to rotate. Both ends of the rotating shaft 411 may be rotatably supported at both side walls of the water storage tank 31 through a bearing, respectively.

Specifically, the gear assembly 422 may include a primary gear coaxially connected to an output shaft of the motor 421 and a secondary gear engaged with the primary gear, and the rotational shaft 411 of the drum 41 is coaxially connected to the secondary gear. Since the rotational speed of the drum 41 need not be too fast, the gear assembly 422 can be a reduction gear set, where the number of teeth of the secondary gear is greater than the number of teeth of the primary gear.

In some embodiments, a partition 43 is further disposed in the air duct and located above the drum 41, and the partition 43 is used for guiding all the air flow entering the air duct through the air inlet to the drum 41, so that all the air flow in the air duct passes through the water washing purification and/or humidification of the drum, and the comprehensiveness of the purification and/or humidification treatment of the air flow is improved.

Specifically, the partition 43 may include a first section 431 covering the drum 41 and a second section 432 extending from an end of the first section 431 toward the intake vent. The first section 431 may have an arc structure having the same shape as a partial section of the drum 41, so that the fit between the first section 431 and the drum 41 is more close to prevent the air from flowing through the gap between the first section 431 and the drum 41 as much as possible. The air inlet may be located at a higher position than the roller 41, and the second section 432 may extend obliquely upward from the end of the first section 431 to a position at or near the air inlet to guide the air flow entering the air duct from the air inlet.

In some embodiments, the air inlet may be located radially outside the drum 41 such that the air flow entering the air duct through the air inlet flows toward the drum 41 along the radial direction of the drum 41. In the embodiment shown in fig. 1, the air inlet includes an indoor air inlet 11 and an outdoor air inlet 12, and both the indoor air inlet 11 and the outdoor air inlet 12 are located at the radial outer side of the drum 41. Therefore, the design of the air duct is simplified, the air flow path between the air inlet and the roller 41 is shortened, and the air flow resistance is reduced.

In some embodiments, the drum 41 includes a rotating shaft 411 extending horizontally and a plurality of rotating disks 412 disposed through the rotating shaft 411 at intervals, so as to take out the water in the water storage tank 31 through the rotating disks 412 when the drum 41 rotates and to wash-purify and/or humidify the air flow by the water attached to the rotating disks 412 when the air flow passes through the drum 41 through a gap between two adjacent rotating disks 412.

Therefore, a gap is formed between every two adjacent rotating disks 412, when the airflow flows to the drum 41 along the radial direction of the drum 41, the airflow can flow through the gap between the two adjacent rotating disks 412, and the drum 41 hardly generates any resistance to the airflow, so that the air outlet speed of the air outlet 13 is hardly influenced. When the drum 41 rotates, the water in the water tank 31 adheres to the rotating disk 412 and is carried out by the rotating disk 412. When the air flow passes through the gap between the adjacent two rotating disks 412, it comes into contact with the water attached to the rotating disks 412, thereby being washed with water and/or humidified. The rotatable disk 412 provides a reliable, large contact area for the air stream with the water, and the water is distributed relatively evenly over the rotatable disk 412, thereby ensuring that the water is in sufficiently effective contact with the air stream. Moreover, the arrangement of the plurality of rotating discs 412 can ensure that the air flow flowing through the drum 41 can contact with water, thereby improving the air flow purification effect and efficiency. As the drum 41 is continuously rotated, the water adhered to the rotary disk 412 is continuously renewed to maintain a good washing purification capacity for a long time.

Fig. 4 is a schematic configuration view of a rotary disk according to an embodiment of the present invention, and fig. 5 is a schematic enlarged view of a portion a of fig. 4. In some embodiments, the rotating discs 412 are disposed on the rotating shaft 411 in a penetrating manner, and each rotating disc 412 includes two opposite end surfaces perpendicular to the rotating shaft 411, and each end surface is provided with densely arranged ribs 4123 to form densely arranged slots 4124 on the end surface.

The slots 4124 not only have a larger surface area relative to the flat surface but also can accommodate more water and have a greater retention capacity for water under capillary suction. Therefore, the densely arranged ribs 4123 and slots 4124 not only increase the total area of the rotary disk 412 that can be contacted with the airflow to a great extent, but also effectively increase the amount of water attached to the entire end surface, so that sufficient water is contacted with the airflow, and further improve the purification efficiency and the purification effect.

In some embodiments, the ribs 4123 extend at an end face in a bent manner such that at least a portion of the formed slots 4124 extend at a bent manner. The bent and extended ribs 4123 and the grooves 4124 have a plurality of corner points, and the corner points generate a larger capillary suction force to the water, so that the water holding capacity of the rotary disk 412 and the amount of the carried water can be further improved, thereby further improving the purification efficiency and the purification effect of the air flow.

In some embodiments, the ribs 4123 may be regularly shaped ribs evenly distributed on the end face such that the formed slots 4124 are evenly distributed and regularly shaped. Accordingly, the water holding capacity of each region of the rotary disk 412 can be equalized, the amount of water carried out can be made relatively uniform, and the air flow passing through the drum 41 can be relatively uniformly washed, purified and/or humidified.

In some embodiments, a center of each of the rotating discs 412 is provided with a connecting hole 4121 for the rotating shaft 411 to penetrate through, and the periphery of the connecting hole 4121 is provided with two flanges 4125 extending in directions away from each other and protruding from two end surfaces respectively. The oppositely disposed flanges 4125 of two adjacent rotary disks 412 abut to form a constant gap between the two adjacent rotary disks 412. Therefore, the problems that the gap between two adjacent rotating disks 412 is changed or even disappears due to factors such as shaking and deviation of the rotating disks 412 in the rotating process of the drum 41 can be avoided, and the influence on the airflow flowing and the airflow purifying effect between two adjacent rotating disks 412 can be avoided. Meanwhile, the flange 4125 increases the contact area between each rotating disc 412 and the rotating shaft 411, so that the supporting stability of the rotating discs 412 is improved, and the rotating discs are prevented from shaking relative to the rotating shaft 411 during rotation.

Since the flange 4125 is located at the center of the rotary disk 412 and the rotary disk 412 has a relatively large diameter, it may not be possible to effectively prevent the outer circumferential edge of the rotary disk 412 from being shaken or shifted by simply relying on the flange 4125. To this end, in some embodiments, each end surface of each rotary disk 412 is provided with a distance post 4126 protruding therefrom, and the distance posts 4126 on the facing end surfaces of two adjacent rotary disks 412 abut to form a constant gap between the two adjacent rotary disks 412. Because the distance posts 4126 are located on the end surface, the distance posts 4126 of the two rotating disks 412 can support the whole disk body of the rotating disks 412 well after being abutted, so that the problems that the gap between two adjacent rotating disks 412 is changed or even disappears due to factors such as shaking and deviation of the rotating disks 412 in the rotating process of the drum 41 are effectively solved, and the influence on the airflow flowing and airflow purification effects between two adjacent rotating disks 412 is avoided.

In some embodiments, the distance between the gauge posts 4126 and the outer edge of the rotating disc 412 is greater than the distance between the gauge posts 4126 and the flange 4125. That is, the distance posts 4126 are closer to the outer side edge of the rotating disk 412, whereby the distance posts 4125 and the flange 4125 can support the outer side and the inner side of the rotating disk 412, respectively, and the rotating disk 412 is less likely to have any shaking or deviation under the combined action of the two, improving the distance maintaining effect.

Fig. 6 is a schematic structural view of a rotary disk according to another embodiment of the present invention. In some embodiments, each rotating disk 412 has a plurality of honeycomb holes 4120 cut therein for retaining water. It can be understood that compared with the structural design of the ribs, the grooves and the like, the honeycomb holes 4120 can hold a larger amount of water, so that the amount of water brought out of the rotating disc 412 can be increased, and the purification effect and the purification efficiency of the air flow can be further improved.

Further, the rotary disk 412 may be a curved plate extending in a wave shape to form a plurality of ridges 4128 and a plurality of valleys 4127 on both sides of the rotary disk 412. Thereby increasing the surface area of the rotary disk 412. Further, each ridge 4128 and each valley 4127 are formed with a plurality of honeycomb holes 4120. Thus, increasing the number of the honeycomb holes 4120 not only increases the total area of the rotary disk 412 that can be contacted with the air stream, but also increases the amount of water held by the entire rotary disk 412 so that a sufficient amount of water is contacted with the air stream, further improving the purification efficiency and purification effect.

In these embodiments, the same or similar structure of the flange 4125, the spacer 4126, etc. as the embodiment shown in fig. 4 may be provided on the rotating disc 412, and will not be described herein.

Fig. 7 is a schematic structural view of an air treatment device according to another embodiment of the present invention, in which broken-line arrows indicate the general flow direction of air flow. In some embodiments, the drum 41 includes a rotation shaft 411 extending horizontally and a plurality of rotation plates 413 arranged in a central emission shape centering on the rotation shaft 411, each rotation plate 413 having a plurality of honeycomb holes to take out water in the water storage tank 31 through the honeycomb holes when the drum 41 rotates to allow the air flow to blow off the water held in the honeycomb holes when the air flow head-on flows to the rotation plates 413, thereby performing water washing purification and/or humidification on the air flow by the water held in the honeycomb holes.

When the drum 41 rotates, the plurality of rotating plates 413 thereof are alternately submerged in the water storage tank 31 and alternately float out of the water. The airflow flowing in the radial direction of the drum 41 flows to the rotating plate 413 floating out of the water surface in a head-on direction when passing through the drum 41. Note that "facing" in the present invention means that the airflow flows against the rotating plate 413 or flows toward the plate surface of the rotating plate 413, and the case where the airflow direction is parallel to the rotating plate 413 is excluded.

When the drum 41 rotates, some of the water in the water storage tank 31 is retained in the honeycomb holes of the rotating plate 413 and is carried out of the water storage tank 31 with the rotation of the rotating plate 413. When the air current head-on along the radial direction of the roller 41 flows to the rotating plate 413 above the water surface, the water kept in the honeycomb holes of the rotating plate is blown off by the air current, and the air current is washed, purified and/or humidified during the contact with the water in the honeycomb holes. Because honeycomb holes on the rotating plate are much larger than the aperture of the filter element in the prior art, the resistance encountered when the airflow flows through the honeycomb holes is relatively small, and the influence on the air outlet speed of the air outlet 13 is small.

In some embodiments, the rotating plate 413 may be a square plate. The length direction of the rotating plate 413 is parallel to the rotating shaft 411, the width direction of the rotating plate 413 is perpendicular to the rotating shaft 411, and one long side of the rotating plate 413 is adjacent to the rotating shaft 411. From this, increased the face area of rotor plate 413 as far as possible to can set up more honeycomb holes, can reduce the resistance that produces the air current on the one hand, on the other hand, can also improve the water yield that rotor plate 413 brought out, improved the purifying effect and the purification efficiency to the air current.

In some embodiments, the included angle between any two adjacent rotating plates 413 is the same. Thereby, it is possible to ensure that the air flow is uniformly water-washed for purification and/or humidification, with the rotation speed of the drum 41 being constant.

FIG. 8 is a schematic block diagram of an air treatment device according to yet another embodiment of the present invention, in which the dashed arrows indicate the general direction of air flow. In some embodiments, the drum 41 includes a rotating shaft 411 extending along a vertical direction and a plurality of water stirring plates 414 disposed on the rotating shaft 411 at intervals, each water stirring plate 414 is disposed obliquely with respect to a horizontal plane, so that when the drum 41 rotates, water in the water storage tank 31 is forced to rise along a gap between two adjacent water stirring plates 414 into an airflow flow path in which an upper section of the drum 41 is located by the water stirring plates 414, thereby performing water washing purification and/or humidification on the airflow in the airflow flow path.

Specifically, when the drum 41 rotates, the water stirring plates 414 can stir the water in the water storage tank, and since the water stirring plates 414 are inclined, they can promote the water to rise along the gap between two adjacent water stirring plates 414 into the airflow flow path above the water surface of the water storage tank 31, so as to contact with the airflow in the airflow flow path, and the airflow is washed with water and/or humidified. More importantly, the rotating shaft 411 is vertically arranged, and the plurality of water stirring plates 414 arranged on the rotating shaft 411 in a penetrating manner are obliquely arranged, so that the roller 41 forms a plurality of gaps which are tightly arranged from top to bottom, water in an airflow flow path which rises to the position above the water surface of the water storage tank 31 along the gaps is uniformly distributed from top to bottom, and the airflow in the airflow flow path can be uniformly washed, purified and/or humidified.

In some embodiments, each of the water-stirring plates 414 is perforated with honeycomb holes, so that part of water is retained in the honeycomb holes during the water rises along the gap between two adjacent water-stirring plates 414. The honeycomb holes of at least part of the agitating plate 414 above the water surface of the water storage tank 31 are located in the airflow flow path to allow the airflow to blow down the water held in the honeycomb holes when the airflow is flowing head-on to the agitating plate 414, thereby washing the airflow with water for purification and/or humidification.

In some embodiments, at least a portion of the at least partially splash plate 414 is submerged in the water within the tank 31 such that the at least partially splash plate 414 has an upper section that is above the water level of the tank 31 and in the airflow flow path above the tank 31. The airflow within the air chute may flow through the upper section of the at least partially splash plate 414. The honeycomb holes of the water-stirring plate 414 are distributed at least in the upper section of the water-stirring plate 414 to ensure the air flow passing through the honeycomb holes.

In some embodiments, the plurality of water stirring plates 414 are disposed in parallel, and the acute angle between the water stirring plates 414 and the horizontal plane is any angle value in the range of 30-80 °. For example, the acute angle between the water-agitating plate 414 and the horizontal plane may be 30 °, 40 °, 50 °, 60 °, 70 °, or 80 °. If the acute angle formed between the water stirring plate 414 and the horizontal plane is too large, for example, greater than 80 °, the inclination degree of the water stirring plate 414 is small, which may result in too small an area of the water stirring plate 414 above the water surface for contacting with the air flow, and thus the efficiency of water washing and purifying the air flow is low and the effect is poor. If the acute angle formed between the water-stirring plate 414 and the horizontal plane is too small, for example, less than 30 °, the inclination of the water-stirring plate 414 is large, which causes the difficulty of water rising along the gap between two adjacent water-stirring plates 414 to be large, and the washing and purifying effect is also not good.

In some embodiments, the water stirring plate 414 may be a square plate or a circular disc with the rotating shaft 411 as a center, and the water stirring plate 414 with such a shape has a large surface area, so as to provide a large area for water to contact with the air flow, thereby further improving the cleaning effect and efficiency of the water washing.

The applicant has appreciated that a problem with the water cleaning of the air flow by the drum 41 is that after the air treatment device 1 is used for a period of time, certain contaminants may accumulate on the drum 41, and if the contaminants are not cleaned in time, the contaminants on the drum 41 may be thicker, the service life of the drum 41 and the water attachment capacity of the drum 41 are affected, and therefore the air flow cleaning effect is affected.

To this end, in some embodiments, the air treatment device 1 further comprises a cleanliness detection device and an automatic cleaning device 80. The cleanliness detection means is used to detect the cleanliness of the drum 41 so as to timely acquire the contamination condition of the drum 41. The automatic washing device 80 is used for washing the drum 41 in a controlled manner, thereby realizing self-cleaning of the drum 41 and restoring the water washing purification and humidification capability of the drum 41.

In some embodiments, at least a partial region of the drum 41 is transparent; the cleanliness detecting means includes a light emitter 71 and a light receiver 72 respectively provided on both sides of the transparent area of the drum 41 to judge the light transmittance of the transparent area based on the light received by the light receiver 72, thereby judging the cleanliness of the drum 41 based on the light transmittance.

The washing of the drum 41 will be described in detail below by taking the rotating disk of the embodiment shown in fig. 4 as an example.

Fig. 9 is a schematic configuration diagram of an automatic washing apparatus in a washing state according to an embodiment of the present invention, and fig. 10 is a schematic configuration diagram of an automatic washing apparatus in a non-washing state (i.e., an idle state) according to an embodiment of the present invention.

When the drum 41 includes a plurality of rotating disks 412 disposed at intervals, since the drum 41 performs water washing purification on the air stream by the water attached to the rotating disks 412, contaminants in the air stream may be attached to the rotating disks 412. That is, the cleaning of the drum 41 is substantially performed on the rotating disk 412. At this time, the transparent region of the drum 41 may include a transparent detection region 4129 formed on each of the rotating disks 412. The projection of the detection area of each rotary disk 412 in the plane perpendicular to the rotation axis 411 coincides, and the line in which the light emitter 71 and the light receiver 72 are located passes through the detection area 4129 of each rotary disk 412. From this, reduced cleanliness detection device's quantity and structure, be convenient for cleanliness detection device's installation.

In some embodiments, the detection zone 4129 is an annular detection zone concentric with the axis of rotation 411. Thus, the cleanliness of the rotating disk 412 can be detected by the cleanliness detecting means regardless of the position to which the drum 41 is rotated, even during the rotation of the drum 41.

In some embodiments, the automatic cleaning device 80 may be any one of a brush, a nozzle, and an ultrasonic cleaning device.

Specifically, in the embodiment shown in fig. 9 and 10, the automatic cleaning device 80 may include a plurality of brushes 81 arranged at intervals in the direction of the rotation shaft 411, and the automatic cleaning device 80 is configured to be controlled to move toward the direction close to the drum 41 to a cleaning position where the brushes are brought into contact with the end surface of the rotation disc 412 when the cleanliness of the rotation disc 412 is equal to or less than the first minimum cleanliness to clean the rotation disc 412 during the rotation of the rotation disc 412, and to move away from the drum 41 to an initial position at a radially side of the drum 41 when the cleanliness of the rotation disc 412 is equal to or more than a preset standard cleanliness.

In other embodiments, the automatic cleaning device 80 may also include a nozzle and a water pump. The nozzle is disposed toward the drum and communicates with the interior of the water storage tank. The water pump is arranged on a pipeline between the nozzle and the water storage tank and used for pumping water in the water storage tank to the nozzle and spraying the water to the roller through the nozzle so as to clean the roller by using the water in the water storage tank.

In still other embodiments, the automatic cleaning device 80 may also be an ultrasonic cleaning device disposed in the water storage tank 31 for emitting ultrasonic waves and cleaning the roller 41 with the ultrasonic waves.

The applicant has recognised that when the air temperature is low, particularly when fresh air is introduced into the room at an outdoor temperature below zero, it is likely that the air will cause freezing in the storage tank 31 when it comes into contact with water. To this end, in some embodiments, a water tank heating device 33 for heating water in the water storage tank 31 may be disposed in the water storage tank 31 to perform water washing purification and/or humidification on the air flow by using the heated water. When the heated water contacts with the airflow, the heat can be transferred to the airflow, and the temperature of the airflow is further increased. That is to say, this application develops the heating of air current into the heating of water in a new way for purification, humidification, the intensification of air current all go on simultaneously when air current and water contact, and the realization of three kinds of functions does not influence each other, can not only carry out humidification and washing purification to the air effectively, can compensate air temperature, auxiliary heating again.

Further, the tank heating device 33 may be disposed at the bottom of the storage tank 31 to directly contact with water after the storage tank 31 is filled with water, so as to transfer heat to the water, in such a manner that the heat transfer efficiency is high and the heating speed is high. At the same time, it is ensured that water can be heated efficiently by direct contact when there is a small amount of water in the water storage tank 31.

Specifically, the tank heating device 33 may be a heating rod, a heating wire, or the like.

In some embodiments, the casing 10 further has a return air inlet 14 for communicating the indoor environment with the air duct, and the return air inlet 14 is provided with an electrically controlled damper 22; on the airflow flow path in the air duct, the air return opening 14 is located downstream of the water storage tank 31 and the drum-type water washing device, so that the airflow entering the air duct through the air return opening 14 directly flows to the air outlet 13. When the blower 21 is operated, indoor air and/or outdoor fresh air entering the housing 10 through the air inlet can be forced to flow to the air outlet 13 through the air duct. Meanwhile, when the air return opening 14 is opened, part of indoor air can enter the air duct through the air return opening 14 under the action of negative pressure generated by air supply in the casing 10, so that the indoor air is mixed with air flowing through the roller 41 and then is sent out from the air outlet 13. Since the indoor air introduced into the duct through the return air inlet 14 is not humidified by the drum 41, the humidity is relatively low. Therefore, the humidity of the mixed air flow formed by mixing the indoor air entering the air duct through the air return opening 14 and the air flow passing through the drum 41 is lower than that of the air flow humidified by the drum 41.

In some embodiments, the housing 10 defines a filling port 15, the filling port 15 defines a filling box 50 for filling the water into the water storage tank 31, and the filling box 50 is configured to be operatively switchable between a closed position hidden in the housing 10 and closing the filling port 15 and an open position outwardly protruding from the housing 10 to allow water to flow through the filling box 50 to the water storage tank 31. That is, when the water storage tank 31 does not require adding water, the water adding box 50 may be hidden in the housing 10 and close the water adding port 15 without affecting the appearance of the housing 10 and causing water to splash through the water adding port 15. When the water storage tank 31 needs to be filled with water, the water filling box 50 can be pulled out from the housing 10 to extend out of the housing 10, so that water is allowed to flow to the water storage tank 31 through the water filling box 50. After the water storage tank 31 is filled with water, the water filling box 50 is directly pushed into the shell 10. The whole water adding process does not need to move the water storage tank 31 or other components, and the water adding operation is very simple and convenient.

Further, the watering cartridge 50 is pivotally connected to the housing 10, facilitating the user's operation of opening and closing the watering cartridge 50.

In some embodiments, air treatment device 1 further comprises ultraviolet light generating device 34 for emitting ultraviolet light into water storage tank 31 to sterilize water in water storage tank 31. The ultraviolet ray generating device 34 may be disposed in the water storage tank 31. Thus, the ultraviolet rays emitted from the ultraviolet ray generator 34 can be transmitted to the water storage tank 31 through a short path, and the sterilization effect is improved with less ultraviolet ray loss.

In some embodiments, a mist barrier 29 is also provided within the air duct for dehumidifying the airflow passing therethrough. And, on the air current flow path from the air inlet to the air outlet 13, the mist isolation net 29 is positioned at the downstream of the drum-type washing device. When high humidity is not needed indoors, the air flow flowing out of the water washing device 40 can be dehumidified through the fog separation net 29, so that the air flow flowing into the indoor is not only purified by water washing, but also low in humidity, and the whole humidity of the indoor air cannot be influenced.

Specifically, the open-close state and/or the opening degree of the mist barrier net 29 may be adjusted by a drive mechanism.

The application also provides an air conditioner. Fig. 11 is a schematic structural view of an air conditioner according to an embodiment of the present invention. The air conditioner 100 of the present application may include the cabinet 200 and the air treatment device 1 described in any of the above embodiments.

Specifically, the casing 200 is opened with an air introduction port 301 for introducing an air flow therein. The air outlet 13 of the air treatment device 1 is connected to the induced air port 301 to introduce the air flow treated by the air treatment device 1 into the cabinet 200. Therefore, the air flows introduced into the cabinet 200 through the air treatment device 1 are all air flows which are washed, purified and/or humidified, so that the quality of indoor air is improved, and the humidity of the indoor air is improved.

In some embodiments, the air conditioner 100 further includes a jet device 300, and the jet device 300 is configured to controllably cause the airflow outside the air conditioner to flow into the air conditioner and be discharged through the jet outlet thereof, and mix the airflow discharged through the jet outlet with the heat exchange airflow discharged through the heat exchange airflow outlet of the air conditioner 100, so as to avoid the air conditioner 100 from being too cold or too hot, and improve the softness of the air and the comfort experience of the user. That is, the jet device 300 is used to introduce natural air into the air conditioner 100, which is not heat-exchanged by the heat exchanging device of the air conditioner 100, so as to moderate the outlet air temperature of the air conditioner 100.

Further, the induced draft opening 301 may be opened on the jet device 300 of the air conditioner 100 and serve as an air flow inlet of the jet device 300. Therefore, the air flow processed by the air processing device 1 can directly flow out through the jet device 300 and is mixed with the heat exchange air flow and then is sent into the room, the air flow directly sent into the room is washed, purified and/or humidified through the air processing device 1, a corresponding purifying device and/or a humidifying device do not need to be arranged in the air conditioner 100, and the structure of the air conditioner 100 body is simplified.

Further, the air conditioner 100 may be a cabinet air conditioner indoor unit, and the jet device 300 may extend vertically as a whole so that the jet air outlet thereof matches the shape of the air outlet of the cabinet air conditioner indoor unit. In these embodiments, the air inducing opening 301 may be disposed at the bottom of the jet device 300, and the air outlet 13 of the air processing device 1 may be disposed at the top thereof, so as to facilitate connection between the air inducing opening 301 and the air outlet 13.

Of course, in some alternative embodiments, the induced air opening 301 may also be a normal air inlet of the air conditioner 100, and the air flow purified and/or humidified by the air treatment device 1 is sent into the casing 200 through the induced air opening 301, and sent out after being heat-exchanged by the heat exchanging device of the air conditioner 100.
