Detailed Description

The present invention is to provide an air treatment apparatus, fig. 1 is a schematic configuration diagram of an air treatment apparatus according to an embodiment of the present invention, fig. 2 is a schematic cross-sectional view of an air treatment apparatus according to an embodiment of the present invention, and a dotted arrow in fig. 2 indicates a general flow direction of an air flow.

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.

The air treatment device 1 further includes a blower 21, a water storage tank 31 for containing water, and a drum 41.

The blower 21 is disposed in the housing 10 and is used for driving the airflow to flow from the air inlet to the air outlet 13. The fan 21 may be a centrifugal fan, an axial flow fan, or a cross flow fan.

The water storage tank 31 is provided within the housing 10, i.e., in the airflow flow path within the housing 10.

The drum 41 is rotatably disposed in the water storage tank 31, and includes a plurality of rotating disks 412 disposed on a rotating shaft 411 thereof. The drum 41 is arranged to take out the water in the water storage tank 31 through the rotary disk 412 when rotating, so that the air flow is water-washed and purified by the water attached to the rotary disk 412 when the air flow passes through the drum 41.

Specifically, when the drum 41 rotates, part of the water in the water storage tank 31 may adhere to the rotary disk 412 and be carried out with the rotation of the rotary disk 412. When the airflow contacts with the water on the rotating disc 412 when flowing through the roller 41, contaminants such as impurities, lint, water-soluble harmful gas and the like in the airflow are dissolved in the water, thereby realizing water washing purification of the airflow. The rotating disc 412 provides a reliable and large contact area for the air flow and the water, and the water is distributed on the rotating disc 412 more uniformly, so that the water can be ensured to be in full and effective contact with the air flow, and the air flow purification effect and efficiency are improved.

It will be appreciated that the height of the drum 41 in the storage tank 31 may be set such that at least a section of the drum 41 is above the water level of the storage tank 31 when the water in the storage tank 31 reaches a maximum level such that at least a section of the drum 41 is in the airflow flow path and such that at least a section of the drum 41 is submerged in the water when the water in the storage tank 31 reaches a minimum level so as to be able to carry the water out as the drum rotates.

The water level in the water storage tank 31 can be obtained by the existing methods such as a liquid level sensor and a magnetic float, and when the liquid level in the water storage tank 31 is lower than the lowest water level, a user can be prompted to add water into the water storage tank 31 through a display screen, a buzzer and the like.

In some embodiments, the air treatment device 1 further comprises a driving mechanism 42 for driving the rotation of the drum 41. The drive mechanism 42 may include a motor and gear assembly. The motor may be provided on the housing for outputting the driving force. The gear assembly is connected between the motor and the rotating shaft 411 of the drum 41 for transmitting the driving force output from the motor 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.

The applicant has appreciated that a problem with water scrubbing of the air stream using the drum 41 is that after the air treatment device 1 is used for a period of time, certain contaminants may accumulate on the rotating disc 412, and if not cleaned in time, the contaminants may become thicker and thicker on the rotating disc 412, which may affect the life of the rotating disc 412 and the ability of the rotating disc 412 to catch water, thereby affecting the scrubbing effect on the air stream. To this end, the air treatment device 1 of the present application further comprises cleanliness detection means for detecting cleanliness of the rotary disk and an automatic cleaning device 80 for cleaning the rotary disk 412 under control. Thus, the contamination condition of the rotating disk 412 can be timely acquired by the cleanliness detection device. When the cleanliness of the rotary disc 412 is low, the contamination is serious, and the contamination on the rotary disc 412 can be cleaned by the automatic cleaning device 80, so that the self-cleaning of the roller 41 is realized, the service life of the roller is prolonged, and the roller is ensured to have good water washing and purifying capacity for a long time.

Fig. 3 is a schematic configuration diagram of an automatic washing apparatus in a washing state according to an embodiment of the present invention, and fig. 4 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. Referring to fig. 3 and 4, in some embodiments, a plurality of rotating discs 412 are disposed through the rotating shaft 411 at intervals, each rotating disc 412 includes a transparent detection area 4129, and projections of the detection areas of the respective rotating discs 412 in a plane perpendicular to the rotating shaft 411 coincide.

Further, the cleanliness detecting means may include a light emitter 71 for emitting light and a light receiver 72 for receiving light, the light emitter 71 and the light receiver 72 are respectively disposed at both sides of the drum 41 in a direction parallel to the rotating shaft 411, and a straight line in which the light emitter 71 and the light receiver 72 are located passes through the detection area 4129 of each rotating disk 412 to judge the light transmittance of the detection area 4129 based on the light received by the light receiver 72, thereby judging the cleanliness of the rotating disk 412 based on the light transmittance.

The present application provides that a transparent detection area 4129 is provided on each rotating disc 412 and the projections of the detection areas 4129 of the respective rotating discs 412 in a plane perpendicular to the axis of rotation 411 coincide. Therefore, the cleanness of all the rotating discs 412 can be effectively detected only by arranging the pair of the light emitter 71 and the light receiver 72 on the two sides of the roller 41, the number and the structure of the cleanness detection devices are reduced, and the cleanness detection devices are convenient to mount.

In some embodiments, the detection zone 4129 is an annular detection zone concentric with the axis of rotation 411. In these embodiments, the rotating disk 412 may be a flat disk-like structure arranged in parallel. In other embodiments, the projection of the detection zone 4129 in a plane perpendicular to the axis of rotation 411 is in the shape of a ring concentric with the axis of rotation 411. In these embodiments, the rotating disk 412 may be a curved disk-like structure. 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 plurality of rotating disks 412 are arranged in parallel, and each rotating disk 412 has two end surfaces that are arranged opposite to each other. The automatic cleaning device 80 is provided on the side of the drum 41 in the radial direction so as to be in direct contact with the end surface of each rotating disk 412. The automatic cleaning device 80 is configured to controllably move in a direction close to the drum 41 to a cleaning position in contact with the end surface of the rotating disc 412 when the cleanliness of the rotating disc 412 is equal to or less than a first minimum cleanliness to clean the rotating disc 412 during rotation of the rotating disc 412, and to controllably move in a direction away from the drum 41 to an initial position at a radially side of the drum 41 when the cleanliness of the rotating disc 412 is equal to or greater than a preset standard cleanliness.

Therefore, when the drum 41 does not need to be cleaned, the automatic cleaning device 80 is located at the radial side of the drum 41, and does not affect the rotation of the drum 41. When the automatic cleaning device 80 is in the cleaning position, each end face of each rotating disc 412 can be in direct contact with the automatic cleaning device 80, so that the rotating discs 412 can be cleaned more thoroughly and more comprehensively, and the cleaning efficiency and the cleaning effect of the rotating discs 412 are improved.

In some embodiments, the rotation shaft 411 of the drum 41 extends in a horizontal direction, and the air inlet is located at a radially outer side of the drum 41 so that the air flow entering the housing 10 through the air inlet flows toward the drum 41 in a radial direction of the drum 41 and flows through the drum 41 through a gap between two adjacent rotating disks 412, thereby performing water washing purification on the air flow by using water attached to the rotating disks 412. Specifically, 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.

Further, the automatic cleaning device 80 is disposed above the drum 41 to be distant from the water storage tank 31, and thus is not affected by water in the water storage tank 31, and does not generate a large resistance to the flow of the air flow, thereby reducing the influence on the flow rate of the air flow.

In some embodiments, the plurality of rotating disks 412 are equally spaced and each rotating disk 412 has the same thickness. 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. 3 and 4, the automatic cleaning device 80 may include a plurality of brushes 81 arranged at intervals along the rotating shaft 411, the distance between two adjacent brushes 81 corresponds to the thickness of the rotating disc 412, and the thickness of the brushes 81 corresponds to the distance between two adjacent rotating discs 412. When the automatic cleaning device 80 is in the cleaning position, the plurality of brushes 81 may be inserted into the plurality of gaps formed by the plurality of rotating disks 412 at intervals, respectively. Moreover, the brush 81 in the gap between two adjacent rotating disks 412 can reliably contact with the end faces of the two rotating disks 412 which are arranged in opposite directions, the two rotating disks 412 cannot extrude the brush 81, and the brush 81 is prevented from being deformed.

Further, the length of the brush 81 may be slightly greater than the radius of the rotating disc 412. The distance of downward movement of the automatic cleaning device 80 is set to make the bottom end of the brush 81 equal to or lower than the height of the rotating shaft 411 when the automatic cleaning device 80 is at the cleaning position, so as to ensure that the cleaning range of the brush 81 can cover the whole area of the rotating disc 412, further improve the comprehensiveness of cleaning the rotating disc 412, and avoid the problem that the periphery of the center of the rotating disc 412 cannot be cleaned.

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.

Fig. 5 is a schematic structural view of a rotary disk according to an embodiment of the present invention, and fig. 6 is a schematic enlarged view of a portion a of fig. 5. In some embodiments, each end surface of the rotating disk 412 is provided with closely spaced ribs 4123 to form closely spaced slots 4124 in 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.

Furthermore, a connection hole 4121 is formed in a center of each of the rotation discs 412 for the rotation shaft 411 to penetrate therethrough, and two flanges 4125 extending in directions away from each other and protruding from two end surfaces are disposed on a periphery of the connection hole 4121. That is, the coupling hole 4121 is provided at both side peripheries thereof with a flange 4125, and each flange 4125 protrudes from the end surface of the rotating disk 412. Each flange 4125 has an annular cylindrical shape.

Further, the oppositely disposed flanges 4125 of the adjacent two rotary disks 412 abut to form a constant gap between the adjacent two 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, each rotating disk 412 is perforated with a plurality of honeycomb holes for holding water. Understandably, compared with the structural design of the convex ribs, the concave grooves and the like, the honeycomb holes can hold a larger amount of water, so that the total amount of water brought out from the rotating disc 412 can be increased, and the purification effect and the purification efficiency of the air flow are further improved. With the continuous rotation of the drum 41, the water retained in the honeycomb holes is continuously renewed to maintain good water washing purification capacity for a long time.

In some embodiments, the cleanliness detection means is further configured for controlled detection of the cleanliness of the water within the storage tank 31. The air treatment device 1 further comprises a prompting device 90, wherein the prompting device 90 is used for controllably sending a prompting signal for instructing to replace the water in the water storage tank 31 when the cleanliness acquired again after the rotating disc 412 is cleaned by the automatic cleaning device 80 is less than the second minimum cleanliness.

When the cleanliness obtained again by the cleanliness detection device is still low after the automatic cleaning device 80 cleans the rotating disc 412, it indicates that the degree of contamination of the water in the water storage tank 31 is high, that is, the cleanliness detection device can also detect the cleanliness of the water in the water storage tank 31. When the cleanliness of water is lower, the prompting device 90 can send out a prompting signal, so that a user can be timely reminded to replace the water in the water storage tank 31, and the use experience of the user is improved.

Specifically, the prompting device 90 may be a display device, a buzzer, or the like.

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, 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 net 29 is also provided within the housing 10 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 can be dehumidified through the fog separation net 29, so that the air flow flowing into the room is not only purified through 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. 7 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.
