[0045] 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

[0046] 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.

[0047] The present invention provides an air 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 have a humidification effect.

[0048] Please refer to Figures 1 to 3 Specifically, the air purification module 100 in the present invention includes a shell 110 and a rotating body 120. Among them, the shell 110 has a purification air duct 113. Specifically, an air inlet and an air outlet can be opened on the shell 110. The purification air duct 113 connects the air inlet and the air outlet. The indoor air or fresh air enters the shell 110 from the air inlet, and is washed by the water sprayed by the rotating body 120 arranged in the shell 110, and then blown out from the air outlet. In order to distinguish it from the air inlet and air outlet of the air conditioner and facilitate better description later, the air inlet of the shell 110 is defined as the module air inlet 111, and the air outlet of the shell 110 is defined as the module air outlet 112 for explanation. The shell 110 is generally cylindrical and extends in the up and down direction. For example, the shell 110 can be square or circular, etc. In addition, the shell 110 can also be a structure with both ends sealed. In one embodiment, the module air inlet 111 is arranged on the peripheral side of the housing 110, and the opening at the top of the housing 110 is the module air outlet 112, so as to achieve air intake at one end and air outlet at one end. Of course, in other embodiments, the module air outlet 112 may also be arranged on the peripheral side of the housing 110. Preferably, a fan may be arranged on the housing 110 to accelerate the circulation of air in the purification air duct 113 and improve the purification efficiency. It should be noted that the directional indications involved in the embodiments of the present invention (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications also change accordingly.

[0049] Please refer to Figure 2 and Figure 3 The air purification module 100 includes a housing 110, a rotating body 120 and a water supply device. The housing 110 has a purification air duct 113, and the rotating body 120 is rotatably arranged in the purification air duct 113, so that when water is sprayed on the rotating body 120, the water is thrown outward by rotation to generate water particles, which combine with dust in the air to achieve the purpose of purifying the air. The water supply device includes a water tank 140, which is arranged below the housing 110 and connected to the purification air duct 113. The water tank 140 is used to provide water sprayed on the rotating body 120. Among them, a water inlet 151 is opened on the housing 110, and the water inlet 151 is connected to the purification air duct 113.

[0050] In this embodiment, the water thrown out by the rotating body 120 combines with the dust in the purification air duct 113 and falls under the action of gravity. The water inlet 151 opened on the housing 110 is located above the water tank 140 and is connected to the water tank 140 through the purification air duct 113, so that water can be added to the water tank 140 through the water inlet 151. When the air purification module 100 needs to be filled with water, the user does not need to take out the water tank 140, but only needs to add water to the purification air duct 113 from the water inlet 151, so as to avoid frequent movement of the water tank 140 to affect the operation of other components, and the water inlet 151 is high for easy operation, thereby reducing the user's squatting action.

[0051] Based on the previous embodiment, please refer to Figure 3 and Figure 4 A guide member 153 is provided at the water adding port 151 , and the guide member 153 is protruded from the outside of the shell 110 . A water adding channel 150 is formed in the guide member 153 . An upwardly opened water inlet 152 is provided at the upper end of the water adding channel 150 , and the water inlet 152 is connected to the water adding port 151 through the water adding channel 150 .

[0052] In this embodiment, the user can directly add water to the water inlet 152 from above, and the water flows along the water adding channel 150 through the water adding port 151 into the housing 110, and enters the water tank 140 through the purification air duct 113. The water in the water tank 140 is used to provide water for spraying on the rotating body 120. Adding water from above is more convenient for users to operate and is not easy to splash.

[0053] For further information, see Figure 4 and Figure 5 The water adding channel 150 is arranged in a downwardly curved arc shape at one end near the water adding port 151. In this way, when adding water, the water entering the water inlet 152 can flow more smoothly to the central area of ​​the purification air duct 113 when entering the water adding port 151 under the guidance of the arc-shaped water adding channel 150, and is not easy to splash out or accumulate.

[0054] In the case where there is an opening below the housing 110 or there is a gap between the water tank 140 and the housing, the water entering the purification air duct 113 is likely to overflow from the opening or gap, and if the water falls directly from a high place, it will collide with the water in the water tank 140, which will easily produce splashes, which will not only generate noise, but also splash onto some electronic components, thus affecting the practical life of the air purification module 100. For this reason, in one embodiment, refer to Figure 5 A water guide groove is also provided in the purification air duct 113, and the water guide groove is provided below the water inlet 151, for receiving the water added from the water inlet 151 and guiding the water to the water tank 140 below. In this embodiment, the water entering the water inlet 152 enters the water tank in an orderly manner under the guidance of the water guide groove, and it is not easy to generate splashes or noise, and it is not easy to overflow.

[0055] For further information, see Figure 5 The water guide groove includes an annular groove 181 and a confluence groove 182 provided on the inner wall of the shell, and a drainage groove (not shown in the figure) provided on the upper side of the water tank 140. The confluence groove 182 extends in the up-down direction to connect the annular groove 181 and the drainage groove. When the user adds water, the water flows into the water inlet 151 through the guidance of the water guide channel 150, and further flows along the inner wall of the shell 110 to the annular groove 181, and then is guided downward to the upper side of the water tank 140 through the confluence groove 182 connected with the annular groove 181, and finally is guided into the water tank 140 through the drainage groove on the upper side of the water tank 140. In this embodiment, through the setting of the water guide groove, the water added from the water inlet 152 is guided, so that the water flow is orderly guided from a high place to the water tank 140 at the bottom of the shell 110 without generating water splashes or splashes.

[0056] The water supply channel 150 can have various shapes. In one embodiment, see Figure 8 The water supply channel 150 is gradually narrowed from the water inlet 152 to the water supply port 151, that is, the water supply channel 150 is funnel-shaped. Figure 4 and Figure 7 The water adding channel 150 is arranged in a step shape from the water inlet 152 to the water adding port 151, so that the area of ​​the water inlet 152 is larger than the area of ​​the water adding port 151. In this way, when adding water, the water adding channel 150 can hold a part of the water, and the water poured into the water adding channel 150 is not easy to overflow or splash, and the water adding operation is more convenient.

[0057] The water inlet 151 on the housing 110 may cause the airflow flowing through the purification air duct 113 to overflow, resulting in air volume loss, thereby reducing the purification effect of the air purification module 100. For this reason, in this embodiment, the water inlet 151 can be closed when no water is added. Figure 8 The air purification module 100 further includes a cover 171, which is movably disposed at the water inlet 152, so as to have a closed state where the cover is disposed at the water inlet 152, or an open state where the cover is away from the water supply port. Figure 6 The air purification module 100 further includes a plug 172, which is movably disposed in the water supply channel to have a blocked state of being plugged into the water supply channel, or an open state of being away from the water supply channel. In this way, the cover 171 can be opened or the plug 172 can be taken out when adding water, and the cover 171 can be closed or plugged in after the water is added. When the air purification module 100 is working, the air volume will not be reduced due to the presence of the water inlet 151, thereby ensuring the purification effect of the air purification module 100.

[0058] In order to facilitate the user to control the amount of water added, in one embodiment, refer to Figure 7 and Figure 8 The air purification module 100 further includes a water level gauge 141, which is disposed in the water tank 140 and is used to indicate the amount of water in the water tank 140. In this way, the user can control the water addition according to the indication of the water level gauge 141 to prevent insufficient or excessive water addition from causing damage to the components. The water level gauge 141 can be in various forms, such as a transparent scale disposed on the side wall of the water tank 140, as long as it can indicate the amount of water in the water tank 140. In one embodiment, please refer to Figure 5 The water level gauge 141 includes a transparent tube 1411 and a buoy 1412. The transparent tube 1411 is disposed at the upper end of the water tank 140, the lower end of the buoy 1412 is disposed in the water tank 140, and the upper end of the buoy 1412 is inserted in the transparent tube 1411. In this way, the water volume in the water tank 140 is marked in a simple and clear manner, and the height of the water level gauge is relatively high, which is convenient for users to observe and add water according to the water volume.

[0059] There are many methods for spraying water onto the rotating body 120, for example, the water outlet 131 arranged around the rotating body 120 can spray water onto the rotating body 120, or water can be directly transported into the hollow rotating body 120. In one embodiment, a water supply channel extending along the axis of rotation is formed in the rotating body 120, and the air purification module 100 also includes a water pump 132, the water inlet end of the water pump 132 is connected to the water tank 140, and the water outlet end of the water pump 132 is connected to the water supply channel. The peripheral side of the rotating body 120 is provided with a water throwing channel (not shown in the figure) connected to the water supply channel. In this embodiment, the water entering the water supply channel is ejected from the water throwing channel to form tiny water particles, and is ejected along the tangential direction of the rotating body 120 under the rotation of the rotating body 120, and the dust in the air contacts and fuses with the high-speed water particles, thereby purifying the air.

[0060] In another embodiment, the water supply device further includes a water supply pipe 130 and a water pump 132, the water inlet end of the water pump 132 is connected to the water tank 140, the water outlet end of the water pump 132 is connected to the water supply pipe 130, and the water outlet 131 of the water supply pipe 130 is arranged in the housing 110 to provide water for spraying onto the rotating body 120. In this embodiment, please refer to Figure 2, the water outlet 131 of the water supply pipe 130 is arranged below the rotating body 120, the water flow is ejected toward the rotating body 120, and ejected along the tangent direction of the rotating body 120 under the rotation of the rotating body 120, the dust in the air contacts and fuses with the high-speed water particles, thereby purifying the air. Alternatively, a water supply pipe 130 installation space extending along the rotation axis is formed in the rotating body 120, the water supply pipe 130 is inserted into the water supply pipe 130 installation space, the water outlet 131 of the water supply pipe 130 is arranged in the water supply pipe 130 installation space, and a water throwing channel connected to the water supply pipe 130 installation space is opened on the peripheral side of the rotating body 120, water is ejected at high speed from the water outlet 131 of the water supply pipe 130, forming fine water droplets, the ejected water droplets are thrown out through the external water throwing channel, and ejected along the tangent direction of the rotating body 120 under the rotation of the rotating body 120, the dust in the air contacts and fuses with the high-speed water particles, thereby purifying the air. In this way, better purification effect can be achieved.

[0061] In this embodiment, when the air purification module 100 is working, the linear speed of the outer edge of the rotating body 120 is 10m / s~45m / s. When the linear speed of the outer edge of the rotating body 120 is too small, the speed of the water thrown out by the rotating body 120 is small, and the air purification effect is poor. When the linear speed of the outer edge of the rotating body 120 is too large, the energy consumption of the rotating body 120 is large and the noise generated is large, and continuing to increase the linear speed of the outer edge of the rotating body 120 has little effect on improving the air purification effect.

[0062] Preferably, in this embodiment, when the air purification module is working, the linear speed of the outer edge of the rotating body 120 is 20m / s to 30m / s. At this time, the rotating body 120 has the advantages of good purification effect, reasonable energy consumption and low noise.

[0063] In one embodiment, see Figure 2 and Figure 3 A filter screen 121 is provided on the circumference of the rotating body 120, and the filter screen 121 extends radially outward from the outer periphery of the rotating body 120. The filter screen 121 is used to receive water sprayed onto the rotating body 120, so that the water on the filter screen 121 performs centrifugal motion during high-speed rotation, thereby forming a large number of tiny water particles on the mesh disk of the filter screen 121, and the water particles are thrown outward and contact the air in the purified air duct 113 to absorb the particles in the air to purify the air.

[0064] In order to further improve the purification effect of the air purification module 100, please refer to Figure 2 The air purification module further includes a negative ion generator 161 and an IFD purification device 162 . The negative ion generator 161 is disposed at the module air outlet 112 , and the IFD purification device 162 is disposed in the purification air duct 113 and above the rotating body 120 .

[0065] In this embodiment, the IFD purification device 162 uses a strong electric field with dielectric materials as carriers to exert a huge attraction on the charged particles moving in the air, adsorbing the moving particles in the air while only generating a small airflow impedance, and collecting and killing bacteria, microorganisms, etc. attached to the particles in the strong electric field. The negative ion generator 161 generates negative ions to make the indoor air healthier and charge the particles in the air, which helps the purification effect of the IFD purification device 162. The air entering the purified air duct 113 is first washed and purified by the rotating body 120 to adsorb large particles in the air, and then passes through the IFD purification device 161 to adsorb the residual particles in the air, thereby reducing the use burden of the IFD purification device 161, saving electricity, and extending the service life of the IFD purification device 161.

[0066] On the basis of the previous embodiment, a drain net 160 is provided between the rotating body and the IFD module. The drain net 160 plays the role of water blocking and ventilation, preventing the water thrown out by the rotating body 120 from splashing onto the electronic components, thereby extending the service life of the air purification module 100.

[0067] The present invention also provides an air conditioner indoor unit, see Figure 1 The air conditioner indoor unit includes a casing 200 and an air purification module 100. The specific structure of the air purification module 100 refers to the above embodiment. Since the air conditioner indoor unit includes the air purification module 100, it has all the effects brought by the air purification module 100, which will not be repeated here. Among them, the air conditioner indoor unit also includes a heat exchanger and a heat exchange fan. The casing 200 extends in the up and down direction. The casing 200 is provided with a heat exchange air inlet, a heat exchange air outlet 210 and a heat exchange air duct (not shown) connecting the heat exchange air inlet and the heat exchange air outlet 210. The heat exchanger (not shown) and the heat exchange fan (not shown) are arranged in the heat exchange air duct. The 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 210.

[0068] There are many ways to fix the air purification module 100 and the housing 200. For example, in some embodiments, the air purification module 100 and the housing 200 are fixed by buckles; in some embodiments, the air purification module 100 and the housing 200 are fixed by screws; in some embodiments, the air purification module 100 and the housing 200 are fixed by welding. The fixing method of the air purification module 100 and the housing 200 is not limited here, as long as the two can be connected.

[0069] The air purification module 100 can be installed inside or outside the housing 200. The following is an example of the air purification module 100 being installed inside the housing 200. In one embodiment, the air purification module 100 is installed at the bottom of the housing 200. Since the air purification module 100 is installed at the bottom of the housing 200 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 220 and a purification air outlet 230 are provided on the peripheral side of the housing 200. The purification air inlet 220 is connected to the module air inlet 111, and the purification air outlet 230 is connected to the module air outlet 112 (the purification air outlet 230 is specifically connected to the air duct formed by the air duct housing 171). Since the rotating body 120 is wrapped by the housing 110 and then installed in the housing 200, the housing 110 can block the water thrown out by the rotating body 120 from flowing to the inner wall of the housing 200, so other components on the inner wall of the housing 200 can be prevented from being wetted and damaged. In addition, a plurality of module air inlets 111 are provided on the peripheral side of the shell 110 to allow air to enter from multiple circumferential positions, thereby better increasing the contact area with water.

[0070] The following is a detailed description of the air purification process: indoor air or fresh air enters the housing 200 from the purification air inlet 220 under the action of the purification fan, and flows into the purification air duct 113 from the module air inlet 111. The water pump 132 transports the water in the water tank 140 to the water supply channel or water supply pipe 130, and sprays the water toward the rotating body 120; the rotating body 120 rotates at a high speed, generating centrifugal force to throw the water out to the surroundings, forming fine water flow or water particles, and the air is fully in contact with the water flow or water particles in the purification air duct 113, and the particles in the air adhere to the water and fall off, and the purified air flows upward, and flows into the air duct of the purification fan through the module air outlet 112, and finally blows out from the purification air outlet 230 on the housing 200.

[0071] 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.
