Referring to fig. 1, the present invention provides an air purification module 100, wherein the air purification module 100 can be applied to an indoor unit 200 of an air conditioner. The air purification module 100 is used for purifying air and sending the purified air to the indoor environment, so as to improve the air quality of the indoor environment.

Referring to fig. 2 to 4, in an embodiment of the air purification module 100 of the present invention, the air purification module 100 includes a housing 110, a rotating body 120 and a water supply pipe 130. Wherein the housing 110 is provided with an air inlet 1101 and an air outlet 1102. The rotating body 120 is rotatably mounted in the housing 110, the rotating body 120 is provided with an air outlet path 1202 extending along the rotation axis thereof and communicating with the air outlet 1102, the rotating body 120 has a bottom wall 121, an inner peripheral wall 122 surrounding the air outlet path 1202, and an outer peripheral wall 123 spaced from the inner peripheral wall 122; the rotary body 120 is formed with an air inlet path 1201 through which air enters from the outer peripheral wall 123 and flows into the air outlet path 1202 through the inner peripheral wall 122, so as to communicate the air inlet 1101 with the air outlet path 1202. The water supply pipe 130 is provided in the air outlet duct 1202 to supply water to the inner peripheral wall 122 so that the water is thrown out from the outer peripheral wall 123 by the rotating body 120 when the rotating body 120 rotates.

Specifically, the casing 110 includes a casing body 111, and a wind-guiding casing 112 and a casing cover 113 sequentially mounted on the casing body 111. Wherein the case body 111 is provided with an air inlet 1101 and the case cover 113 is provided with an air outlet 1102. The rotating body 120 and the water supply pipe 130 are both located within the case body 111. The rotating body 120 is rotatably installed in the casing body 111, the water supply pipe 130 is fixedly installed in the casing body 111, and the water supply pipe 130 extends into the air outlet passage 1202 of the rotating body 120 to supply water to the inner circumferential wall 122 of the rotating body 120. It should be noted that the water supply pipe 130 is in a stationary state with respect to the rotating body 120 and does not rotate together with the rotating body 120.

Referring to fig. 4 and 5, when the air purification module 100 is operated, the rotating body 120 rotates at a high speed, and the air flow path is opposite to the flow path of the water droplets, i.e., the air and the water droplets flow in opposite directions, so as to achieve the collision flushing purification. Wherein, the flow path of the air is as follows: the rotating body 120 rotates at a high speed, negative pressure is formed in the air outlet duct 1202, and air enters the casing 110 from the air inlet 1101 under the difference between the internal pressure and the external pressure; then passes through the air inlet path 1201 and flows into the air outlet path 1202; finally, the air is blown out from the air outlet duct 1202 to the air outlet 1102 and blown out from the air outlet 1102. In the process of the air passing through the intake air passage 1201, the air first passes through the outer peripheral wall 123, enters the inside of the rotary body 120, flows from the outside to the inside of the rotary body 120, and then passes out of the inner peripheral wall 122 and flows into the intake air passage 1202.

And the flow path of the water is: the water supply pipe 130 supplies water to the inner circumferential wall 122 of the rotating body 120, and when the rotating body 120 rotates at a high speed, the water on the inner circumferential wall 122 is thrown out from the inside to the outside in the radial direction by a centrifugal force, and the thrown water droplets are reduced into water droplets having a small particle size. In the water throwing process, the water drops moving outwards collide with the air flowing inwards in the air inlet duct 1201 in the rotating body 120, so that the water throwing and air purifying by the super-gravity are realized. Such as settling fine particles, pollen, etc. in the air, or dissolving floating microorganisms, bacteria, volatile organic compounds, etc. (e.g., formaldehyde, benzene, TOVC) in the water.

In the technical solution of the present invention, the air outlet path 1202 extending along the rotation axis and communicating with the air outlet 1102 is provided on the rotating body 120, and the air inlet path 1201 for the air to flow into the air outlet path 1202 from the outer peripheral wall 123 through the inner peripheral wall 122 is formed on the rotating body 120, so as to communicate the air inlet 1101 and the air outlet path 1202. The water is supplied to the inner peripheral wall 122 by the water supply pipe 130 provided in the air outlet duct 1202, so that when the rotating body 120 rotates, the rotating body 120 throws out the water from the outer peripheral wall 123, and the water drops thrown out from the inside collide with the air flowing from the outside to the inside. In the collision process, the collision contact time is long, and the particle size of the water drops is extremely thinned, so that the water drops are fully contacted with air, and the purification efficiency is effectively improved.

Referring to fig. 4 and 5, based on the above embodiments, the air outlet duct 1202 may be disposed to extend horizontally or vertically (i.e., vertically). In the present embodiment, the air outlet duct 1202 extends in the vertical direction of the air purification module 100, so that the air flows from the bottom to the top.

Accordingly, air inlet 1101 is provided at the lower portion of casing 110, and communicates with the lower end of air outlet passage 1202 through air inlet passage 1201; the air outlet 1102 is provided at an upper portion of the casing 110 and communicates with an upper end of the air outlet duct 1202. The design can fully utilize the longitudinal space of the air treatment module and reduce the transverse dimension of the air treatment module.

Referring to fig. 4 and 5, the air treatment module further includes a cleaning fan 150, and the cleaning fan 150 is located between the air outlet 1102 and the air outlet duct 1202. Specifically, the purge fan 150 is attached to the case cover 113. When the cleaning fan 150 is operated, a large negative pressure is formed in the air outlet passage 1202, and the air is driven to flow into the air outlet passage 1202 from the air inlet passage 1201 at an accelerated speed, and is blown upward toward the air outlet 1102 through the air outlet passage 1202.

Referring to fig. 4 and 5, the air cleaning module 100 further includes a water supply tank (not shown) located below the rotating body 120, the water supply tank being communicated with a water supply pipe 130 through a water pipe to serve as a water source of the rotating body 120. The water pipe is hidden between the outer peripheral wall 123 of the rotating body 120 and the inner wall surface of the case 110. The water supply pipe 130 is supplied with a sufficient amount of water using the water supply tank. Of course, the water supply of the water supply pipe 130 may also be provided by the user.

Referring to fig. 4 and 5, in the water supply pipe 130, the extending direction of the water supply pipe 130 coincides with the extending direction of the air outlet passage 1202, and the water inlet 131 of the water supply pipe 130 is formed at the upper end or the lower end of the water supply pipe 130. The water inlet 131 of the water supply pipe 130 is provided at the upper end of the water supply pipe 130 herein in view of the water flowing downward from the top under the gravity thereof.

The water supply pipe 130 has water discharge holes (not shown) formed through a circumferential wall thereof, and some of the water discharge holes are spaced apart from each other in a longitudinal direction of the water supply pipe 130, and the other water discharge holes are spaced apart from each other in a circumferential direction of the water supply pipe 130. The rotary body 120 is provided with a water throwing hole (not shown) through it, and the water spraying hole is communicated with the water throwing hole.

When the rotating body 120 throws water, the water pipe 130 sprays water through the water throwing holes on the inner circumferential wall 122 of the plurality of water spraying holes, the rotating body 120 rotates at a high speed to throw the water in the water throwing holes, and the thrown water is thrown outwards along the tangent line of the outer circumferential wall 123, thereby enhancing the purification effect.

As for the fixing manner of the water supply pipe 130, the water supply pipe 130 may be directly connected to the housing 110 itself, or may be connected to the housing 110 through a connector, which is not limited herein and will be described in detail later.

Referring to fig. 4 and 5, in an embodiment, in order to guide the air in the air outlet path 1202 to the air outlet 1102, optionally, the air purification module 100 further includes an air duct 140 fixedly connected to the housing 110, and the air duct 140 extends into the air outlet path 1202 to communicate the air outlet path 1202 with the air outlet 1102.

Since the water supply pipe 130 needs to be fixedly installed in the air outlet path 1202 and the air guide duct 140 is located in the air outlet path 1202 and is fixedly connected to the housing 110, the water supply pipe 130 can be disposed on a side wall of the air guide duct 140 to simplify the fixing structure. Optionally, the water supply pipe 130 is disposed around the air guide duct 140, so that the water supply pipe 130 uniformly sprinkles water along the circumferential inner wall 122 of the air guide duct 140 to the inner circumferential rotating body 120.

Referring to fig. 2, 4 and 5, the water supply pipe 130 is integrally formed with the air guide duct 140, and a sidewall of the air guide duct 140 is hollow, so that the water supply pipe 130 is formed on a wall of the air guide duct 140. By the design, the number and the working procedures of manufacturing parts can be reduced, and the production efficiency is improved. Here, in order to fix the air guide duct 140, the upper end of the air guide duct 140 extends into the air inducing shell 112 and is connected and fixed with the air inducing shell 112.

Referring to fig. 4, for the rotating body 120, the rotating body 120 is driven by the driving device to rotate. The driving device may be the structure of the indoor unit 200 itself of the air conditioner, or may be driven by the motor of the cleaning fan 150 in a linkage manner. In this embodiment, the air purification module 100 further includes a driving device (not shown) mounted to the housing 110, and connected to the rotating body 120 to drive the rotating body 120 to rotate along the rotation axis.

In one embodiment, to facilitate the installation of the rotator 120, the air purification module 100 further includes a rotation bracket frame 170 rotatably installed in the housing 110, and the rotator 120 is installed on the rotation bracket frame 170 to be rotated by the rotation bracket frame 170.

Specifically, a rotating shaft (not shown) is provided at the bottom of the rotating bracket frame 170, the rotating shaft is mounted to the water supply tank through a bearing, and the driving device is connected to the rotating shaft to drive the rotating bracket frame 170 to rotate the rotating body 120. The rotating body 120 is driven to rotate by rotating the bracket frame 170 to support the gravity of the rotating body 120, so that the load of the rotating body 120 is reduced, and the rotating body 120 is not easy to deform or throw out under high-speed rotation.

For a specific structure of the rotating body 120, the rotating body 120 should be a porous structure having a ventilation aperture and a water throwing aperture. The ventilation pore and the water throwing pore are communicated pores. The pores can be holes, strip-shaped capillary pores, gaps and the like. Accordingly, the rotating body 120 may be formed using a void material, such as a multi-layer mesh-like structure. The rotating body 120 may also be a hollow cylindrical structure, and the inner circumferential wall 122 and the outer circumferential wall 123 are respectively provided with apertures (e.g., circular holes, capillary holes, mesh holes, etc.), some of which are used for ventilation, and some of which are used for throwing out the water supplied from the water supply pipe 130.

Here, in order to form the intake air passage 1201, a plurality of intake holes are provided in the outer peripheral wall 123, a plurality of outlet holes 1221 are provided in the inner peripheral wall 122, and the intake holes and the outlet holes 1221 communicate with each other to form the intake air passage 1201. The positions of the inlet and outlet holes 1221 can be variously selected, and four kinds are exemplified here:

referring to fig. 6, in the first embodiment, the air outlet holes 1221 are located at a portion of the inner circumferential wall 122 near the bottom wall 121, and the water supply pipe 130 supplies water to a portion of the inner circumferential wall 122 located at an upper side of the air outlet holes 1221. At this time, a plurality of the intake holes may be arranged at intervals throughout the wall surface of the outer circumferential wall 123. That is to say, the whole wall surface of the peripheral wall 123 forms an air inlet surface, and the air passes through the peripheral wall 123 and enters the inside of the rotating body 120, and in the process, the air collides with the water drops moving outwards in the radial direction of the rotating body 120, and then is extruded to flow downwards to the air outlet hole 1221, and flows into the air outlet duct through the air outlet hole 1221.

Referring to fig. 7, the second embodiment is different from the first embodiment in that a plurality of the air inlet holes are disposed in the middle and/or the upper portion of the outer circumferential wall 123. That is, only the middle and/or upper wall surface of the outer peripheral wall 123 forms an air inlet surface through which air enters the inside of the rotating body 120, and in the process, the air collides with the water droplets moving outward in the radial direction of the rotating body 120, and then is extruded to flow downward to the air outlet hole 1221, and flows into the air outlet duct through the air outlet hole 1221. The downward flowing path of the air is effectively prolonged, and the purification effect can be enhanced.

Referring to fig. 8, in the third embodiment, the difference from the first embodiment is that the rotating body 120 further includes a top wall 124, the air outlet hole 1221 is located at a portion of the inner circumferential wall 122 adjacent to the top wall 124, and the water supply pipe 130 supplies water to a portion of the inner circumferential wall 122 located at a lower side of the air outlet hole 1221. At this time, a plurality of the intake holes may be arranged at intervals throughout the wall surface of the outer circumferential wall 123. Similarly, the entire wall surface of the outer peripheral wall 123 forms an air inlet surface, and the air passes through the outer peripheral wall 123 and enters the inside of the rotating body 120, and in the process, the air collides with the water drops moving outwards in the radial direction of the rotating body 120, and then floats upwards to the air outlet 1221 under the action of the buoyancy of the air, and flows into the air outlet duct through the air outlet 1221.

Referring to fig. 9, in the fourth embodiment, the difference from the third embodiment is that a plurality of the air intake holes are disposed in the middle and/or lower portion of the outer peripheral wall 123. That is, only the middle and/or lower wall surface of the outer peripheral wall 123 forms an air inlet surface through which air enters the inside of the rotating body 120, and in this process, the air first collides with the water droplets moving outward in the radial direction of the rotating body 120, and then floats upward to an outlet air under the buoyancy of the air, and flows into the outlet air duct through the outlet hole 1221. The downward flowing path of the air is effectively prolonged, and the purification effect can be enhanced.

Based on any of the above embodiments, in consideration of the collision and purification of air and water droplets in the rotating body 120, in order to enhance the purification effect, a water-breaking structure (not shown) may be further provided between the inner peripheral wall 122 and the outer peripheral wall 123 to break up and thin the water supplied from the water supply pipe 130 to the rotating body 120, so that the particle size of the water droplets is further reduced, and the water droplets are sufficiently contacted with the air, thereby improving the purification efficiency.
