[0002] As users' demand for air purification increases, air conditioners with purification modules are becoming more popular. The air purification module can realize centrifugal water removal through the composition of a tube body and a rotating body.

[0040] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The present invention provides a water spray assembly, a purification module, an air conditioner indoor unit and an air conditioner. The air purification module can be used alone or in combination with the air conditioner. Specifically, the air conditioner can be a wall-mounted unit, an air conditioner indoor unit or a mobile air conditioner. The air purification module can purify indoor air or fresh air by water washing, so that the air flowing into the room is cleaner and can achieve a humidification effect.

[0043] In the embodiment of the present invention, Figures 1 to 5 As shown, the air purification module includes a housing 60, a rotating body 30, a driving device 40 and a water spraying assembly. Among them, the housing 60 is provided with an air inlet, an air outlet and a purification air duct 61 connecting the air inlet and the air outlet. The indoor air or fresh air enters the housing 60 from the air inlet, and is cleaned by the water sprayed by the rotating body 30 arranged in the housing 60, and then blown out from the air outlet. In order to distinguish from the air inlet and air outlet of the air conditioner, and facilitate the subsequent better description, the air inlet of the housing 60 is defined as the air inlet 62, and the air outlet of the housing 60 is defined as the air outlet 63 for explanation. The housing 60 is generally cylindrical and extends in the up and down direction. For example, the housing 60 can be square or circular, etc. In addition, the housing 60 can also be a structure with two ends sealed. In one embodiment, the air inlet 62 is arranged on the peripheral side of the housing 60, and the open opening at the top of the housing 60 is the air outlet 63. Of course, in other embodiments, the air outlet 63 can also be arranged on the peripheral side of the housing 60. The water spray assembly includes a first tube body 10 and a second tube body 20 . The first tube body 10 is connected to the second tube body 20 . A plurality of water spray holes 21 are formed on a circumferential surface of the second tube body 20 .

[0044] The rotating body 30 is arranged in the purification air duct 61, and the rotating body 30 is used to throw water around the housing 60. Specifically, the rotating body 30 has a water supply pipe installation space 31 extending along its rotation axis, and a water throwing hole 32 connected to the water supply pipe installation space 31 is opened on the peripheral side of the rotating body 30. The second tube body 20 of the water spray assembly is inserted into the water supply pipe installation space 31, and the first tube body 10 is connected to the water source. The purified water enters the second tube body 20 through the first tube body 10 and is then sprayed to the rotating body 30 from the water spray hole 21. In practical applications, the air purification module also includes a water tank 70 and a water pump 71, the water inlet end of the water pump 71 is connected to the water tank 70, and the water outlet end of the water pump 71 is connected to the first tube body 10 of the water spray assembly. The water tank 70 is arranged below the purification air duct 61 so that the water thrown out by the rotating body 30 can flow back to the water tank 70 to achieve the recycling of water.

[0045] The driving device 40 is installed on the housing 60, and the output shaft of the driving device 40 is connected to the rotating body 30 to drive the rotating body 30 to rotate along the axis of rotation. The driving device 40 is specifically a motor or other driving member that can drive the rotating body 30 to rotate. The driving device 40 drives the rotating body 30 to rotate along the axis of rotation, and the rotating body 30 generates a huge centrifugal force. When the water sprayed from the water spray hole 21 passes through the rotating body 30, it will be broken up by the rotating rotating body 30 to form fine water particles or water flow. When the air enters the housing 60, it comes into contact with the water particles, and the air is purified and humidified. By throwing water from the rotating body 30, the water flow can be broken up to form finer water particles, so that the contact area between the air and the water particles is larger, and the contact between the two is more sufficient, so the purification effect is better. In practical applications, the rotational linear speed of the rotating body 30 is 10m / s to 45m / s, preferably 20m / s to 30m / s. In this way, the water can be more fully dispersed, effectively increasing the distribution of water droplets and water mist, while reducing the noise generated and improving practicality.

[0046] The combination rate of the thrown water droplets and the air is affected by factors such as the number and distribution of the water droplets. Therefore, if more water spray holes 21 are opened on the second tube body 20, the distribution of the water droplets in all directions will be denser. The number of water spray holes 21 is affected by the circumferential area of ​​the second tube body 20. When the aperture of the water spray hole 21 is constant, the larger the circumferential area of ​​the second tube body 20, the more water spray holes 21 can be opened. From the geometric relationship, it can be seen that if the radial dimension of the second tube body 20 is directly increased, that is, the cross-sectional area of ​​the second tube body 20 is increased, the circumferential area of ​​the second tube body 20 will also increase accordingly, but this will reduce the water pressure entering the second tube body 20, thereby reducing the flow rate of the water flowing out of the water spray hole 21, so that the water cannot effectively reach the rotating body 30. Based on the above situation, the inner diameter of the first tube body 10 is defined as r1, and its flow path cross-sectional area is S1=πr12, and the cross-sectional area defined by the inner edge of the second tube body 20 is S2≤S1.

[0047] The outer circumference corresponding to the cross section of the first tube body 10 is L1, and the outer circumference corresponding to the cross section of the second tube body 20 is L2, where L1≤L2.

[0048] When the water spray assembly is in working state, the water pressure in the first pipe body 10 is P1, and the flow rate is V1; the water pressure in the second pipe body 20 is P2, and the flow rate is V2, P1≤P2, V1≤V2.

[0049] Specifically, in one embodiment of the present application, the second tube body 20 includes a plurality of branch pipes 22 extending in parallel, the plurality of branch pipes 22 are connected to the first tube body 10, and the peripheral surface of the branch pipes 22 is provided with a plurality of water spray holes 21. In this embodiment, the cross-sectional shape of the conventional tube body is a common geometric shape, and the water inlet area of ​​the conventional tube body can be equal to the area enclosed by the edge of its cross section; for the conventional tube body, the circumference of the circle is the smallest among geometric shapes of equal area, so this embodiment defines a base circle, and the circumference of the base circle can be regarded as the minimum cross-sectional circumference of the conventional tube body of equal cross-sectional area. The effective water inlet area of ​​the second tube body 20 can be regarded as equal to the area of ​​the base circle. The second tube body 20 is composed of a plurality of branch pipes 22 extending in parallel, and the area enclosed by the edges of the plurality of branch pipes 22 is greater than the sum of the water inlet areas of the plurality of branch pipes 22, that is, in fact, the effective water inlet area of ​​the second tube body 20 is smaller than the cross-sectional area of ​​the second tube body 20, so that the cross-sectional area of ​​the second tube body 20 is greater than the area of ​​the base circle. From the geometric relationship, it can be seen that the larger the area, the larger the circumference, so the overall circumference of the second tube body 20 is correspondingly larger than the circumference of the base circle, that is, under the same height, the circumferential area of ​​the second tube body 20 will be larger than the circumferential area of ​​a conventional tube body with the same water inlet cross-sectional area. Therefore, under the premise that the effective water inlet area of ​​the second tube body 20 remains unchanged, that is, under the premise that the water inlet pressure remains unchanged, the circumferential area of ​​the second tube body 20 is effectively increased, thereby increasing the number of water spray holes 21 opened on the circumference of the second tube body 20.

[0050] The branch pipe 22 may be cylindrical, or may be other shapes such as an ellipse or a polygon. Multiple branch pipes 22 may be arranged in a straight line direction or in a circumferential direction. Two adjacent branch pipes 22 may be connected to each other or may form a gap. After multiple branch pipes 22 are combined to form the second tube body 20, the circumference of the branch pipe 22 will be partially hidden, and the water spray holes 21 may be opened only on the exposed circumference of the branch pipe 22, or may be opened on the circumference of the branch pipe 22 that is blocked from each other, as long as the second tube body 20 effectively sprays water outward. The specifications of each branch pipe 22 may be set to be the same to facilitate unified production and simplify the production process.

[0051] It should be noted that the descriptions of "first", "second", etc. involved in the embodiments of the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0052] The present invention increases the circumferential area of ​​the second tube body 20 without increasing the cross-sectional area of ​​the second tube body 20, that is, without reducing the water inlet pressure of the second tube body 20, by configuring the second tube body 20 to be composed of a plurality of branch tubes 22 extending in parallel; thereby increasing the number of water spray holes 21 opened on the circumferential surface of the second tube body 20 without reducing the water inlet pressure of the second tube body 20, so as to increase the distribution amount of water discharged from the second tube body 20, refine the water droplet particle size and increase the water droplet coverage rate, so that the ejected water droplets can contact with the air more, improve the combination rate of the water droplets and impurities in the air, and thus improve the purification efficiency of the air purification module.

[0053] Furthermore, if Figure 1 and Figure 2 As shown, the water spray hole 21 is opened on the exposed surface of the branch pipe 22. In this embodiment, the water spray hole 21 is only opened on the exposed surface of the branch pipe 22, that is, the second pipe body 20 is prevented from spraying water in a direction that cannot reach the rotating body 30, thereby improving the effective utilization rate of the water spray hole 21 and increasing the effective water flow rate of the water spray hole 21.

[0054] Furthermore, if Figure 1 and Figure 2 As shown, the branch pipe 22 is a circular pipe. In this embodiment, the branch pipe 22 arranged in a circular pipe can reach the maximum circumference under a certain cross-sectional area, that is, after being combined into the second tube body 20, each branch pipe 22 can have more exposed surfaces, thereby further increasing the circumferential area of ​​the second tube body 20, that is, further increasing the number of water spray holes 21. In practical applications, the opening directions of the water spray holes 21 of two adjacent branch pipes 22 at the adjacent position will intersect, so that the water sprayed from the water spray holes 21 at this position will impact each other to form more scattered water droplets, thereby increasing the coverage rate of water droplets on the rotating body 30, that is, further increasing the coverage rate of water particles in the purification air duct 61 after being thrown out.

[0055] Furthermore, the number of the branch pipes 22 is 2 to 6. Figure 4 As shown, the number of branch pipes 22 can be selected as 4. If the number of branch pipes 22 is greater than 6, the water intake of each branch pipe 22 will be reduced, resulting in insufficient water spraying amount for purifying air; therefore, setting the number of branch pipes 22 to 2 to 6 can effectively increase the circumferential area of ​​the second tube body 20 and ensure the water spraying amount of the second tube body 20, thereby improving the stability of the air purification module.

[0056] Furthermore, if Figure 1 and Figure 2As shown, the plurality of branch pipes 22 are arranged in a ring shape. In this embodiment, the plurality of branch pipes 22 are adjacently arranged along the circumference of the second tube body 20 to enclose the second tube body 20, so that the size of the second tube body 20 as a whole in all directions is more uniform, and the space utilization rate of the space where the second tube body 20 is located is avoided to be reduced due to the excessive size in a single direction, so that the formation of the second tube body 20 is more reasonable, thereby making the overall structure of the air purification module more compact.

[0057] Furthermore, if Figure 1 and Figure 2 As shown, the water inlet ends of the multiple branch pipes 22 are located within the inner edge of the water outlet end of the first tube body 10. The cross-section of the first tube body 10 can be selected to be circular, and the cross-sectional size of the first tube body 10 can be the same as the base circle size defined in the above embodiment. The water outlet of the first tube body 10 and the water inlet of the multiple branch pipes 22 are both located on the end face, and the first tube body 10 has multiple water outlets respectively connected to the water inlet of each branch pipe 22. The water inlet ends of the multiple branch pipes 22 are located within the inner edge of the water outlet end of the first tube body 10, that is, the cross-sectional area of ​​the first tube body 10 is greater than or equal to the cross-sectional area of ​​the second tube body 20, so that the water pressure will increase in the process of water flowing from the first tube body 10 into the second tube body 20, so that the water flow rate sprayed from the water spray hole 21 is higher.

[0058] Furthermore, the inner edges of the plurality of branch pipes 22 are tangent to the inner edge of the first tube body 10. In this embodiment, the extension direction of the plurality of branch pipes 22 is consistent with the extension direction of the first tube body 10, and the inner edges of the plurality of branch pipes 22 are tangent to the inner edge of the first tube body 10, so as to maximize the circumferential area of ​​the second tube body 20 on the basis of ensuring the water inlet pressure of the support rod, thereby maximizing the number of spray holes, further increasing the coverage rate of the water outlet of the second tube body 20, so that the thrown water droplets can contact with the air more, improve the combination rate of the water droplets and impurities in the air, and thus improve the purification efficiency of the air purification module.

[0059] In another embodiment of the present application, at least part of the circumference of the second tube body 20 has a depression 23 to increase the area of ​​the circumference of the second tube body 20, and a plurality of water spray holes 21 are provided on the circumference of the second tube body 20. In this embodiment, the water spray holes 21 are arranged at intervals along the axial direction and circumferential direction of the second tube body 20, and the depression 23 of the second tube body 20 is also provided with water spray holes 21. Referring to the base circle defined in the above embodiment, the cross-sectional area of ​​the second tube body 20 at the depression 23 is equal to the base circle area, and the cross-sectional circumference of the second tube body 20 at the depression 23 is greater than the circumference of the base circle, so that the second tube body 20 increases the circumferential area without increasing the cross-sectional area, so as to increase the number of distribution of the water spray holes 21. It should be noted that the specific shape of the second tube body 20 is not limited, and it is only necessary to satisfy that the cross-sectional circumference of the depression 23 is greater than the circumference of the base circle of equal area. In practical applications, the number of the recess 23 may be one or more; the recess 23 may extend along the circumference of the second tube body 20 or extend along the circumference of the second tube body 20 .

[0060] The air purification module of the present invention increases the circumferential area of ​​the second tube body 20 without increasing the cross-sectional area of ​​the second tube body 20 by providing the circumferential surface of the second tube body 20 with a depression 23; thereby increasing the number of water spray holes 21 opened on the circumferential surface of the second tube body 20 without reducing the water inlet pressure of the second tube body 20, so as to increase the distribution amount of water discharged from the second tube body 20, refine the particle size of water droplets, so that the ejected water droplets can contact with the air more, increase the combination rate of water droplets and impurities in the air, and thus improve the purification efficiency of the air purification module.

[0061] Furthermore, the number of the recesses 23 is multiple, and the multiple recesses 23 are arranged at intervals along the circumference of the second tube body 20. In this embodiment, the recess 23 can extend along the axial direction of the second tube body 20 to further increase the circumferential area of ​​the second tube body 20. The recess 23 can be arranged in a concave arc shape, or in an inward pointed tip shape, or in an inwardly concave plane shape. A tip or a convex arc surface can be formed between two adjacent recesses 23. Multiple recesses 23 are arranged at intervals along the circumference of the second tube body 20, which can not only further increase the circumferential area of ​​the second tube body 20, but also make the distribution of the water spray holes 21 at various positions on the circumference of the second tube body 20 more uniform, so that the water flow sprayed from the water spray holes 21 is more uniform, so as to further improve the purification efficiency of the air purification module.

[0062] Furthermore, the cross section of the second tube body 20 is arranged in a convex arc between two adjacent depressions 23. The depression 23 is formed between two adjacent convex arc surfaces, and the tangent slopes of different parts of the convex arc surfaces are different, so that the opening directions of the water spray holes 21 opened on the convex arc surfaces are also different, thereby making the opening directions of the water spray holes 21 different in the circumferential direction of the second tube body 20, and the change trend of the opening direction is more uniform.

[0063] In another embodiment of the present application, Figure 3 and Figure 4 As shown, the second tube body 20 includes an inner tube 24 and an outer tube 25, the outer tube 25 is sleeved with the inner tube 24, the outer tube 25 and the inner tube 24 are both connected to the first tube body 10, the first tube body 10 is connected to the gap between the outer tube 25 and the inner tube 24, and a plurality of water spray holes 21 are provided on the circumference of the outer tube 25. In this embodiment, the inner tube 24 can be arranged in a solid column shape or in a hollow column shape with both ends closed, as long as water does not flow into the inner tube 24. A water gap 26 is formed between the inner tube 24 and the outer tube 25, and the water spray holes 21 are connected to the water gap 26. The cross section of the water gap 26 is arranged in a ring shape. Referring to the base circle defined in the above embodiment, on the basis of a certain cross-sectional area of ​​the inner tube 24, if the effective water inlet area of ​​the water gap 26 is equal to the area of ​​the base circle, the cross-sectional area of ​​the outer tube 25 should be larger than the area of ​​the base circle, so that the circumference of the cross section of the outer tube 25 will be larger than the circumference of the base circle, that is, the circumferential area of ​​the second tube body 20 will be larger than the circumferential area of ​​a conventional tube body with the same water inlet area; thus, under the premise that the effective water inlet area of ​​the second tube body 20 remains unchanged, that is, under the premise that the water inlet pressure remains unchanged, the circumferential area is effectively increased, thereby increasing the number of water spray holes 21 opened on the circumference of the second tube body 20.

[0064] The water spray assembly of the present application is formed by setting the second tube body 20 to be formed by an outer tube 25 sleeved with an inner tube 24, and connecting the first tube body 10 with the gap between the inner tube 24 and the outer tube 25, so that the water inlet cross-section of the second tube body 20 is arranged in an annular shape. Compared with the conventional tube body with a circular water inlet cross-section, the second tube body 20 with an annular water inlet cross-section has a larger circumferential area when the water inlet cross-sectional area is equal; that is, under the premise of the same water inlet pressure, the number of water spray holes 21 that can be opened on the circumference of the second tube body 20 is greater, thereby increasing the distribution amount of water output from the second tube body 20, refining the water droplet particle size and increasing the water droplet coverage rate, so that the thrown water droplets can contact with the air more, improving the combination rate of water droplets with impurities in the air, thereby improving the purification efficiency of the air purification module.

[0065] Furthermore, if Figure 3As shown, the peripheral wall of the outer tube 25 protrudes from the peripheral wall of the first tube body 10. In this embodiment, the first tube body 10 and the second tube body 20 can be arranged in a circular tube shape. Referring to the base circle defined in the above embodiment, the water outlet area of ​​the first tube body 10 can be equal to the area of ​​the base circle, so that the cross-sectional area of ​​the outer tube 25 is larger than the cross-sectional area of ​​the first tube body 10, so as to further increase the peripheral area of ​​the outer tube 25, that is, further increase the number of water spray holes 21 opened on the peripheral surface of the outer tube 25, thereby increasing the distribution amount of water outlet from the second tube body 20, refining the water droplet particle size and increasing the water droplet coverage rate, so that the thrown water droplets can contact with the air more, improve the combination rate of water droplets and impurities in the air, and thus improve the purification efficiency of the air purification module.

[0066] The present invention also provides an air purification module, which includes:

[0067] A housing 60, wherein the housing 60 has a purification air duct 61;

[0068] A rotating body 30 is rotatably disposed on the purification air duct 61, the rotating body 30 has a rotation axis, a water supply pipe installation space 31 extending along the rotation axis is formed in the rotating body 30, and a water throwing hole 32 communicating with the water supply pipe installation space 31 is opened on the circumference of the rotating body 30; and,

[0069] A nozzle assembly, the specific structure of which refers to the above-mentioned embodiments. Since the air purification module adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here; wherein the second tube body 20 of the water spray assembly is inserted into the water supply pipe installation space 31.

[0070] Furthermore, if Figure 6 and Figure 7 As shown, the air purification module further includes a driving device 40 disposed on the housing 60 , and an output shaft of the driving device 40 is connected to the rotating body 30 to drive the rotating body 30 to rotate.

[0071] like Figure 6 and Figure 7As shown, the present invention also proposes an air-conditioning indoor unit, which includes a casing 50 and an air purification module. The specific structure of the air purification module is referred to the above embodiment. Since the air-conditioning indoor unit includes the air purification module, it has all the effects brought by the air purification module, which will not be repeated here. Among them, the air-conditioning indoor unit also includes a heat exchanger and a heat exchange fan. The casing 50 extends in the up and down direction, and the casing 50 is provided with a heat exchange air inlet, a heat exchange air outlet 51 and a heat exchange air duct (not shown) connecting the heat exchange air inlet and the heat exchange air outlet 51. The heat exchanger (not shown) and the heat exchange fan (not shown) are arranged in the heat exchange air duct. Indoor air enters the heat exchange air duct from the heat exchange air inlet, and after heat exchange through the heat exchanger, it is blown out from the heat exchange air outlet 51.

[0072] There are many ways to fix the air purification module to the housing 50. For example, in some embodiments, the air purification module and the housing 50 are fixed by buckles; in some embodiments, the air purification module and the housing 50 are fixed by screws; in some embodiments, the air purification module and the housing 50 are fixed by welding. The fixing method of the air purification module and the housing 50 is not limited here, as long as the two can be connected.

[0073] The air purification module can be installed inside or outside the housing 50. The following description will be made by taking the installation of the air purification module inside the housing 50 as an example. In one embodiment, the air purification module is installed at the bottom of the housing 50. Since the air purification module is installed at the bottom of the housing 50 and is arranged in the up and down direction, it can avoid occupying the lateral space and reduce the occupation of the indoor lateral space. A purification air inlet 52 and a purification air outlet 53 are provided on the peripheral side of the housing 50. The purification air inlet 52 is connected to the air inlet 62, and the purification air outlet 53 is connected to the air outlet 63 (the purification air outlet 53 is specifically connected to the air duct formed by the air duct shell). Since the rotating body 30 is wrapped by the housing 60 and then installed in the housing 50, the housing 60 can prevent the water thrown out by the rotating body 30 from flowing to the inner wall of the housing 50, so that other parts on the inner wall of the housing 50 can be prevented from being wetted and damaged. In addition, a plurality of air inlets 62 are provided on the peripheral side of the housing 60 to achieve air intake at multiple positions in the circumference, so as to better increase the contact area with water.

[0074] The following is a detailed description of the air purification process: indoor air or fresh air enters the housing 50 from the purification air inlet 52 under the action of the purification fan, and flows into the purification air duct 61 from the air inlet 62. The water pump transports the water in the water tank to the water spray pipe, and the water spray pipe sprays the water in all directions; the rotating body 30 rotates under the drive of the first driving device 40, and the high-speed rotating body 30 generates centrifugal force to throw the water in all directions, forming fine water flow or water particles. The air is fully in contact with the water flow or water particles in the purification air duct 61, and the particles in the air adhere to the water and fall off. The purified air flows upward and flows into the air duct of the purification fan through the air outlet 63, and finally blows out from the purification air outlet 53 on the housing 50.

[0075] The present invention also provides an air conditioner, which includes an air conditioner outdoor unit and an air conditioner indoor unit, wherein the air conditioner indoor unit is connected to the air conditioner outdoor unit via a refrigerant pipe. The specific structure of the air conditioner indoor unit is shown in the above embodiment. Since the air conditioner includes the air conditioner indoor unit, it has all the effects brought by the air conditioner indoor unit, which will not be described in detail here.

[0076] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
