Detailed Description

The present invention first provides an air treatment device, fig. 1 is a schematic structural diagram 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 the general flow direction of 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, and 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. The drum 41 includes a rotation shaft 411 extending vertically and a plurality of rotation plates 412 penetrating the rotation shaft 411 and arranged at intervals on the rotation shaft 411, each rotation plate 412 being disposed to be inclined with respect to a horizontal plane. That is, a gap extending obliquely upward is formed between each adjacent two of the rotating plates 412.

Further, the drum 41 is configured to cause the water in the water storage tank 31 to rise along the gap between two adjacent rotating plates 412 into the airflow flow path above the water surface of the water storage tank 31 by the rotating plates 412 when rotating, so as to water wash and/or humidify the airflow in the airflow flow path.

Specifically, when the drum 41 rotates, the rotating plates 412 can stir the water in the water storage tank, and since the rotating plates 412 are inclined, the water can be promoted to rise along the gap between two adjacent rotating plates 412 to the airflow flow path above the water surface of the water storage tank 31 so as to be contacted with the airflow in the airflow flow path, solid pollutants such as particles and lint 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 moisture, so that the water is washed, purified and/or humidified. More importantly, the rotating shaft 411 is vertically arranged, and the plurality of rotating plates 412 arranged on the rotating shaft 411 in a penetrating mode are obliquely arranged, so that the roller 41 can form 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 air flow in the airflow flow path can be uniformly washed, purified and/or humidified.

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.

Fig. 3 is a schematic cross-sectional view of a rotating plate according to an embodiment of the present invention. In some embodiments, each rotating plate 412 is perforated with honeycomb holes 4121 to allow some water to remain in the honeycomb holes 4121 during the water rising along the gap between two adjacent rotating plates 412. The honeycomb holes 4121 of at least part of the rotating plate 412 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 4121 when the airflow is headed toward the rotating plate 412, thereby water-washing the airflow for purification and/or humidification by the water held in the honeycomb holes 4121.

The honeycomb holes 4121 have a strong ability to hold water and hold a large amount of water. Therefore, the amount of water carried over the entire rotating plate 412 can be increased to ensure the contact time between the air flow and the water, and it can be seen that the air flow is washed and purified and/or humidified by the water in the honeycomb holes 4121, and the effect is better. Moreover, the design of the honeycomb holes 4121 can also greatly reduce the resistance of the rotating plate 412 to the airflow, thereby reducing the effect on the airflow rate.

In some embodiments, the air inlet is 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 4121 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.

In some embodiments, at least a portion of the rotating plate 412 has only a partial section submerged in the water within the storage tank 31 such that the at least a portion of the rotating plate 412 has an upper section above the water surface of the storage tank 31 and in the airflow flow path above the storage tank 31. The airflow within the duct may flow through the upper section of the at least partially rotating plate 412. The cell holes 4121 of the rotating plate 412 are distributed at least in an upper section of the rotating plate 412 to ensure the gas flow through the cell holes 4121.

It is understood that the above description of at least a portion of the pivotal plates 412 may include a portion of the pivotal plates 412 located at an upper portion of the pivotal shaft 411, and the entire pivotal plates 412.

In some embodiments, the plurality of rotating plates 412 are arranged in parallel, and the spacing between any two adjacent rotating plates 412 is the same. Therefore, gaps with the same size can be formed between any two adjacent rotating plates 412, and the size of each gap is equal from top to bottom, so that the same amount of water rising through the gaps between any two adjacent rotating plates 412 can be ensured when the drum 41 rotates, the water flow resistance is reduced, and the uniformity of water distribution on the rotating plates 412 is improved.

In some alternative embodiments, the gaps between the plurality of rotating plates 412 may also be tapered or divergent from bottom to top.

In some embodiments, the plurality of rotating plates 412 are disposed in parallel, and the acute angle between the rotating plates 412 and the horizontal plane is any value in the range of 30-80 °. For example, the acute angle between the rotating plate 412 and the horizontal plane may be 30 °, 40 °, 50 °, 60 °, 70 °, or 80 °. If the acute angle formed between the rotating plate 412 and the horizontal plane is too large, for example, greater than 80 °, the inclination of the rotating plate 412 is too small, which results in too small an area of the rotating plate 412 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 rotating plates 412 and the horizontal plane is too small, for example, less than 30 °, the inclination of the rotating plates 412 is large, which causes the difficulty of water rising along the gap between two adjacent rotating plates 412 to be large, and the washing and purifying effect is also not good.

In some embodiments, the rotating plate 412 may be a square plate or a circular disc with the rotating shaft 411 as a center, and the surface area of the rotating plate 412 with this shape is large, so that a large area can be provided for water to contact with the air flow, and the water washing and purifying effect and efficiency are further improved.

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. 4 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.
