Detailed Description

The present invention first provides an air treatment device, fig. 1 is a schematic structural view of an air treatment device according to an embodiment of the present invention, fig. 2 is a schematic cross-sectional view of an air treatment device according to an embodiment of the present invention, and dotted arrows in fig. 2 indicate an approximate flow path 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 the indoor environment space where the air processing device 1 is located, and the outdoor space in the embodiment of the present invention means the outdoor environment space.

An air duct communicating the air inlet and the air outlet 13 is formed in the housing 10, a fan 21 for driving an air flow to flow from the air inlet to the air outlet 13, a water storage tank 31 for containing water, and a roller 41 rotatably disposed in the water storage tank 31 are disposed in the air duct, and the air flow in the air duct flows to the roller 41 along a radial direction of the roller 41. That is, the direction in which the air flows toward the drum 41 is perpendicular to the rotational axis thereof.

Fig. 3 and 4 are schematic cross-sectional views of a rotating shaft and a part of a rotating plate, respectively, taken along different cross-sectional planes according to an embodiment of the present invention. The drum 41 includes a rotation shaft 411 extending horizontally and a plurality of rotation plates 412 connected to the rotation shaft 411 and arranged in a center-emitting shape centering on the rotation shaft 411, each rotation plate 412 having a plurality of cell holes 4122. The drum 41 is provided to take out the water in the water storage tank 31 through the honeycomb holes 4122 of the rotating plate 412 when rotating, to allow the air flow to blow down the water held in the honeycomb holes 4122 and pass through the honeycomb holes 4122 when the air flow is in head-on direction to the rotating plate 412, thereby water-washing purifying and/or humidifying the air flow by the water held in the honeycomb holes 4122.

When the drum 41 rotates, the plurality of rotating plates 412 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 412 floating out of the water surface while passing through the drum 41. It should be noted that the term "facing" in the present invention means that the airflow flows against the rotating plate 412 or flows toward the surface of the rotating plate 412, and the case where the airflow direction is parallel to the rotating plate 412 is excluded.

When the drum 41 rotates, part of the water in the water storage tank 31 is held in the honeycomb holes 4122 of the rotating plate 412 and is carried out of the water storage tank 31 with the rotation of the rotating plate 4122. When the airflow flows to the rotating plate 412 above the water surface along the radial direction of the roller 41, the water kept in the honeycomb holes 4122 of the rotating plate is blown off by the airflow, and in the contact process with the water in the honeycomb holes 4122, solid pollutants such as particles and flocks in the airflow and water-soluble harmful gases such as formaldehyde and benzene can be dissolved in the water, and meanwhile, the airflow can take away part of the water, so that the water is washed, purified and/or humidified. Since the honeycomb holes 4122 on the rotating plate have a much larger aperture compared to the filter element of the prior art, the resistance encountered when the air flow passes through the honeycomb holes 4122 is relatively small, and the influence on the air outlet speed of the air outlet 13 is small.

Since the sewage after the air flow is washed, purified and humidified falls into the water storage tank 31, the rotating plate 412 rotates back to the water storage tank 31 again along with the rotation of the drum 41, and then the honeycomb holes 4122 can keep new water in the water storage tank 31, and the water kept in the honeycomb holes 4122 is continuously updated repeatedly, so that the better washing and purifying capacity can be kept for a long time.

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 so that at least a section of the rotating plate 412 where the drum 41 floats above the water level 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 when 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 rotating plate 412 may be a square plate. The length direction of the rotating plate 412 is parallel to the rotating shaft 411, the width direction of the rotating plate 412 is perpendicular to the rotating shaft 411, and one of the long sides of the rotating plate 412 is adjacent to the rotating shaft 411. Therefore, the area of the rotating plate 412 is increased as much as possible, so that a large number of honeycomb holes 4122 can be provided, and on the one hand, resistance to the airflow can be reduced, and on the other hand, the amount of water taken out by the rotating plate 412 can be increased, thereby improving the airflow purification effect and efficiency.

In some embodiments, the number of rotating plates 412 may be an even number. The plurality of rotating plates 412 are located in the same plane two by two, and the two rotating plates 412 located in the same plane are integrally formed to form a complete rotating plate 413, and the rotating shaft 411 is inserted into the rotating plate 413. Thus, the number of parts of the drum 41 is reduced, and the assembly process between the rotating plate 412 and the rotating shaft 411 is simplified.

Further, the number of the rotating plate bodies 413 is plural, and the plural rotating plate bodies 413 cross each other at a central line coinciding with the rotating shaft 411 at respective middle portions thereof. Thereby, the layout density of the rotating plate 412 is increased, and the air flow is convenient to be uniformly and comprehensively washed, purified and/or humidified.

In some embodiments, the included angle between any two adjacent rotating plates 412 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.

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.

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 head-on toward the rotating plate 412 of the drum 41 and passes through the honeycomb holes 4122 of the rotating plate 412. Specifically, 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.

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 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 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. 5 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.
