Moreover, the design and integration degree of the gear box is higher, the structure is simple, and the compactness of the structural layout of the air treatment device can be improved.

Detailed Description

The present invention is to provide an air treatment apparatus, fig. 1 is a schematic configuration view of an air treatment apparatus according to an embodiment of the present invention, and fig. 2 is a schematic sectional view of an air treatment apparatus 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 14 communicating the air inlet and the air outlet 13 is formed in the housing 10, and a blower 21, a water storage tank 31 for containing water, and a roller 41 disposed in the water storage tank 31 are disposed in the air duct 14.

The air treatment device 1 further comprises a drive mechanism 50 and a transmission mechanism 60.

The driving mechanism 50 is used for driving the fan 21 and the drum 41 to rotate simultaneously, so as to promote the air flow to flow from the air inlet towards the air outlet 13, and the water in the water storage tank 31 is brought into the air flow path in the air duct 14 by the rotation of the drum 41, so that the air flow in the air flow path is subjected to water washing purification and/or humidification. That is, the fan 21 and the drum 41 share one drive mechanism 50. When the roller 41 rotates, water is brought upwards to the airflow flow path, the water is contacted with the airflow in the airflow flow path, 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 vapor, so that the water vapor is washed, purified and/or humidified.

Further, the applicant considers that the rotation speed of the fan 21 is directly related to the wind speed, and the rotation speed of the drum 41 is directly related to the contact time of the air flow and the water, and the amount of water contacted with the air flow. When the fan 21 and the drum 41 share one driving mechanism 50, it is necessary to comprehensively consider various factors such as the wind speed, the amount of water contacting with the air current, the contact time of the air current with the water, noise, and the like. If the fan 21 and the roller 41 rotate synchronously, when the rotating speed is high, although the requirement of the wind speed is met, the problem that too high rotating speed of the roller 41 causes too much water, high noise and the like in contact with the airflow is caused; when the rotating speed is small, although noise is reduced and proper water quantity contacting with the airflow is ensured, the rotating speed of the fan 21 is too low, so that the problems of low wind speed, too long time of contacting the airflow with the water, over-wet airflow and the like are caused.

To this end, in some embodiments, applicants further design drive mechanism 60. The transmission mechanism 60 is used for transmitting the driving force output by the driving mechanism 50 to the fan 21 and the drum 41 at different transmission ratios so that the rotation speed of the fan 21 is greater than that of the drum 41. That is, the transmission mechanism 60 can be used to realize that the rotation speed of the fan 21 is greater than that of the drum 41 under the driving of the same driving mechanism 50, so that the driving force output by the driving mechanism 50 is fully utilized, the number of the driving mechanisms is reduced, the structure of the air processing device 1 is simplified, the cost is reduced, and the normal flow speed and humidity of the air flow and the operation noise are ensured.

Fig. 3 is a schematic structural block diagram of a driving mechanism, a transmission mechanism, a fan and a drum according to an embodiment of the present invention. In some embodiments, the transmission 60 may be a gearbox. The gear box includes an input shaft 61 coaxially connected with an output shaft of the driving mechanism 50, first and

second output shafts

62 and 63 coaxially connected with a rotation shaft of the fan 21 and a rotation shaft of the drum 41, respectively, and a plurality of gears connected between the input shaft 61 and the first output shaft 62 and/or between the input shaft 61 and the second output shaft 63, the plurality of gears being disposed such that a rotation speed of the first output shaft 62 is greater than a rotation speed of the second output shaft 63.

Specifically, the drive mechanism 50 may be a motor. The output shaft of the motor is coaxially connected with the input shaft 61 of the gear box to input the driving force output from the motor into the gear box. The driving force of the input gear box reaches the first output shaft 62 and the second output shaft 63 through the transmission of a plurality of gears according to different transmission ratios, so that the fan 21 and the roller 41 are driven to rotate according to different rotating speeds through the first output shaft 62 and the second output shaft 63 respectively. The design of gear box integrates the degree higher, and simple structure, can improve the compactness of air treatment facilities 1 structural layout.

In some embodiments, the applicant considers that the requirement of the rotational speed of the fan 21 is relatively large, and therefore, the input shaft 61 of the gearbox may be coaxially connected with the first output shaft 62 thereof, so that the rotational speed of the first output shaft 62 is the same as that of the input shaft 61, that is, the rotational speed of the output shaft of the driving mechanism 50 is the same as that of the fan 21 (see fig. 2), thereby eliminating the trouble of providing gears between the input shaft 61 and the first output shaft 62, simplifying the structure of the gearbox, and reducing the cost.

Further, a plurality of gears of the gear box may be disposed between the input shaft 61 and the second output shaft 63 and form a reduction gear set such that the rotational speed of the second output shaft 63 is less than the rotational speed of the input shaft 61, that is, the rotational speed of the drum 41 is less than the rotational speed of the input shaft 61. Since the rotation speed of the input shaft 61 is the same as that of the fan 21, the purpose that the rotation speed of the drum 41 is lower than that of the fan 21 can be achieved. The specific way of designing the plurality of gears into the reduction gear set is a technology that is easily available to a person skilled in the art, and therefore, the detailed description thereof is omitted here.

Further, when the input shaft 61 of the gear box is coaxially connected with the first output shaft 62 thereof, the positions of the fan 21 and the drum 41 are arranged differently, and the number of gears and/or the gear engagement manner of the reduction gear set are also different. Fig. 2 is a schematic diagram showing an embodiment in which an input shaft 61 of the gear box is coaxially connected to a first output shaft 62 thereof, and a rotation shaft of the fan 21 may be perpendicular to a rotation shaft of the drum 41, and for simplicity, an output shaft of the driving mechanism 50, the input shaft 61 of the gear box, and the first output shaft 62 are simplified as one body in fig. 2.

Specifically, in some embodiments, the rotational axis of the fan 21 may be perpendicular to the rotational axis of the drum 41, that is, the directions of the first output shaft 62 and the second output shaft 63 are perpendicular to each other. At this time, the reduction gear set has odd number of direction changes, that is, the reduction gear set needs odd number of direction changes to realize the power output of the first output shaft 62 and the second output shaft 63 in two directions perpendicular to each other under the power input of the same input shaft 61. The reduction gear set can realize one, three, five and other odd-numbered commutations by helical gears, bevel gears and the like, and the specific gear design is easily obtained by a person skilled in the art and is not described in detail herein. In other embodiments, the rotation axis of the fan 21 and the rotation axis of the drum 41 may be parallel or coincident with each other, that is, the directions of the first output shaft 62 and the second output shaft 63 are parallel or coincident with each other. At this time, the reduction gear set has zero or even number of reversals. That is, the reduction gear set needs to perform even number of reversals or not to perform reversals, so that the power output of the first output shaft 62 and the second output shaft 63 in two directions parallel or overlapped with each other can be realized under the power input of the same input shaft 61. The reduction gear set can realize even number of commutations such as twice, four times, six times and the like through a helical gear, a conical gear and the like, and can also realize no commutation through a common gear, and the specific gear design is easy to obtain by the technical personnel in the field, and is not described again here.

FIG. 4 is a schematic cross-sectional view of an air treatment device according to another embodiment of the present invention. In other embodiments, the plurality of gears of the gearbox may include a drive wheel 641 coaxially connected with the input shaft 61, a first gear set 642 connected between the drive wheel 641 and the first output shaft 62, and a second gear set 643 connected between the drive wheel 641 and the second output shaft 63. It should be appreciated that the first gear set 642 and the second gear set 643 each include at least one gear. That is, power is transmitted between the driving mechanism 50 and the fan 21 and between the driving mechanism 50 and the drum 41 through the gear train, and these embodiments are suitable for the case where the rated rotational speed of the driving mechanism 50 does not match the rotational speed range of the fan 21.

Further, the gear ratio of the first gear set 642 and the gear ratio of the second gear set 643 are set such that the rotational speed of the second output shaft 63 is less than the rotational speed of the first output shaft 62. Therefore, the purpose that the rotating speed of the roller 41 is less than that of the fan 21 can be achieved. The size of the transmission ratio between the first gear set 642 and the second gear set 643 is realized by designing the number of gears and/or the number of gear teeth in the two gear sets, which is a technology easily obtained by those skilled in the art, and therefore, the details are not described herein.

Further, when the position arrangement of the fan 21 and the drum 41 is different, the number of gears and/or the gear engagement manner between the first gear set 642 and the second gear set 643 are also different. Fig. 4 is a schematic diagram of an embodiment in which the input shaft 61 of the gear box is connected to the first output shaft 62 thereof through a gear, and the rotation shaft of the fan 21 may be perpendicular to the rotation shaft of the drum 41.

Specifically, in some embodiments, the rotation axis of the fan 21 and the rotation axis of the drum 41 are perpendicular to each other, and the difference between the number of the commutations of the first gear set 642 and the second gear set 643 is an odd number. That is, the first gear set 642 and the second gear set 643 may both perform reversing at least once, or only one of the gear sets may perform reversing, and in any case, the difference between the reversing times of the two gear sets is odd, so that the power output in the two directions perpendicular to each other, of the first output shaft 62 and the second output shaft 63, can be realized under the power input of the same input shaft 61. The gear set may be reversed one or more times by means of helical gears, bevel gears, etc., and the specific gear design is readily available to those skilled in the art and will not be described further herein. In other embodiments, the rotation axis of the fan 21 and the rotation axis of the drum 41 may be parallel or coincident with each other, that is, the directions of the first output shaft 62 and the second output shaft 63 are parallel or coincident with each other. At this time, the difference between the numbers of commutation times of the first gear set 642 and the second gear set 643 is even or zero. That is, the first gear set 642 and the second gear set 643 may or may not perform reversing at least once, and it is necessary that the difference between the reversing times of the two gear sets is even or the reversing times are the same to achieve the power output of the first output shaft 62 and the second output shaft 63 in the two directions parallel or coincident with each other under the power input of the same input shaft 61. The gear set may be reversed one or more times by means of helical gears, bevel gears, etc., and the specific gear design is readily available to those skilled in the art and will not be described further herein.

It can be seen that, in the present application, the transmission mechanism 60 is designed to be a gear box having an input shaft 61, two output shafts and a plurality of gears, and no matter the fan 21 is arranged in parallel with the rotation shaft of the drum 41 or the fan 21 is arranged perpendicular to the rotation shaft of the drum 41, the reduction and/or the change of the transmission direction can be realized by selecting the shapes and the meshing modes of the plurality of gears in the gear box, so that the purpose of different rotation speeds of the two output shafts is realized, and the flexibility of the position layout among the fan 21, the drum 41 and the transmission mechanism 60 is improved.

The drum 41 may include a rotation shaft 411 and a plurality of rotation disks 412. There are various arrangements of the rotary disk 412 on the drum 41 and the structure thereof. The air flow in the air duct may flow toward the drum 41 in a radial direction of the drum 41.

In some embodiments, referring to fig. 4, the rotating shaft 411 of the drum 41 extends in a vertical direction, and a plurality of rotating disks 412 are disposed on the rotating shaft 411 at intervals. Each rotating disc 412 is arranged obliquely with respect to the horizontal plane. And the drum 41 is arranged to cause the water in the water storage tank 31 to rise along the gap between two adjacent rotary discs 412 into the air flow path above the water storage tank 31 by the rotary discs 412 when rotating, thereby water washing purifying and/or humidifying the air flow in the air flow path.

Further, each rotating disc 412 is provided with honeycomb holes, so that part of water is retained in the honeycomb holes in the process that the water rises along the gap between two adjacent rotating discs 412. The honeycomb holes of at least part of the rotating disc 412 above the water surface of the water storage tank 31 are located in the airflow flow path to allow the airflow to blow off the water held in the honeycomb holes when the airflow is flowing head-on to the rotating disc 412, thereby water washing the airflow for purification and/or humidification by the water held in the honeycomb holes.

FIG. 5 is a schematic cross-sectional view of an air treatment device according to yet another embodiment of the present invention. In some embodiments, the rotation shaft 411 of the drum 41 extends in a horizontal direction, a plurality of rotation disks 412 are disposed through the rotation shaft 411 at intervals, at least an upper region of the rotation disks 412 is in the airflow flow path, and the rotation disks 412 are parallel to the airflow direction in the airflow flow path. The drum 41 is arranged to take out water in the water storage tank 31 through the rotary disks 412 when rotating, to purify the air flow by water adhering to the rotary disks 412 when the air flow passes through the drum 41 through the gap between the adjacent two rotary 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.

Further, a plurality of slits may be formed on an end surface of the rotating disc 412 to improve the water holding capacity of the rotating disc 412 and the amount of carried-out water, thereby improving purification efficiency and purification effect.

Furthermore, a plurality of honeycomb holes can be formed in the rotating disc 412, and the water quantity retained by the honeycomb holes is large, so that the water quantity brought out of the rotating disc 412 can be increased, and the air flow purification effect and the air flow purification efficiency are improved.

FIG. 6 is a schematic cross-sectional view of an air treatment device according to yet another embodiment of the present invention. In still other embodiments, the rotation shaft 411 of the drum 41 extends in a horizontal direction, and the drum 41 further includes a plurality of rotation disks 412 arranged in a center-emitting shape centering on the rotation shaft 411, each rotation disk 412 having a plurality of honeycomb holes. The drum 41 is arranged to take out water in the water storage tank 31 through the honeycomb holes on the rotary disk 412 when rotating to allow the air flow to blow down the water held in the honeycomb holes when the air flow is headed to the rotary disk 412, thereby purifying the air flow by the water held in the honeycomb holes.

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 addition, the ultraviolet rays also have the function of degrading residual chlorine, so that a user can be allowed to directly add tap water into the water storage tank 31, and the problems of high use cost and troublesome use caused by the fact that the conventional device like water washing or humidifying needs to use pure water are solved.

Further, the ultraviolet 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 22 is also disposed within the air chute 14 for dehumidifying the airflow passing therethrough. On the airflow path from the air inlet to the air outlet 13, the mist barrier 22 is located downstream of the water storage tank 31. Therefore, when high humidity is not needed indoors, the air flow flowing out of the water storage tank 31 can be dehumidified through the fog separation net 22, so that the air flow flowing into the indoor room is not only washed and purified, but also the humidity is low, and the whole humidity of the indoor air cannot be influenced.

Further, the air treatment device 1 further comprises a driving mechanism 23, and the driving mechanism 23 is connected with the mist barrier 22 and is used for controllably adjusting the opening and closing state and/or the opening degree of the mist barrier 22. When the mist barrier 22 is in the open state, the mist barrier 22 blocks at least part of the flow cross section of the air duct, so that at least part of the air flow in the air duct flows through the mist barrier 22. Accordingly, when the mist barrier 22 is in the closed state, the mist barrier 22 does not block the flow cross section of the air duct, so that any air flow in the air duct does not pass through the mist barrier 22. The larger the opening of the mist barrier 22 is, the more the flow cross section of the air duct is blocked. When the mist barrier 22 is in the fully open state, the mist barrier 22 blocks all flow-through sections of the air duct, and all air flow in the air duct flows through the mist barrier 22.

In some embodiments, a duct heating device 24 is also provided within the duct 14 for heating the airflow passing therethrough. On the air flow path from the air inlet to the air outlet 13, the air duct heating device 24 is located downstream of the water storage tank 31. Therefore, the air flow can be heated through the air duct heating device 24, so that the temperature of the air flow is improved, and the heating is assisted.

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.
