Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly relates to an air purification module and an indoor air conditioner. Background Art

[0002] With the improvement of living quality, people pay more and more attention to air quality, and the competition of air conditioners with purification functions is becoming more and more fierce. Currently, for the indoor air conditioners on the market, an air purification module is usually installed to purify the air by using the air purification module. Such a conventional air purification module usually adopts a cross-flow manner of water flow and air (as shown in the attached drawings of the specification, air flows from the bottom wall of the rotating body 120 to its top wall, and the water supply pipe 160 sprays water onto the inner peripheral wall of the rotating body 120, and the rotating body 120 rotates to throw the water out from its outer peripheral wall) to purify the air. However, in this cross-flow manner of water flow and air, the contact between air and water flow is not sufficient, resulting in poor mass transfer effect between air and water flow, and thus low purification efficiency. Figure 10 The above content is only used to assist in understanding the technical solution of the present invention. Even if the applicant believes that there are still deficiencies in this technology and writes it into the background art, it does not mean that the applicant admits that this technology is the prior art.

[0042] Please refer to Figure 1 The present invention provides an air purification module 100, and the air purification module 100 can be applied to an air conditioner indoor unit 200. The air purification module 100 is used to purify air and send the purified air to the indoor environment to improve the air quality of the indoor environment.

[0043] Please refer to Figures 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. Among them, the housing 110 is provided with an air inlet 1101 and an air outlet 1102. The rotating body 120 is rotatably installed in the housing 110. The rotating body 120 is provided with an air outlet passage 1202 extending along its rotation axis 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 passage 1202, and an outer peripheral wall 123 spaced from the inner peripheral wall 122; the rotating body 120 forms an air inlet passage 1201 for air to enter from the outer peripheral wall 123 and flow into the air outlet passage 1202 through the inner peripheral wall 122, so as to connect the air inlet 1101 and the air outlet passage 1202. The water supply pipe 130 is disposed in the air outlet passage 1202 and is used to supply water to the inner peripheral wall 122, so that when the rotating body 120 rotates, the rotating body 120 can throw the water out from the outer peripheral wall 123.

[0044] Specifically, the housing 110 includes a housing body 111, a blower housing 112 and a housing cover 113 that are sequentially installed on the housing body 111. Among them, the housing body 111 is provided with an air inlet 1101, and the housing cover 113 is provided with an air outlet 1102. The rotating body 120 and the water supply pipe 130 are both located inside the housing body 111. Among them, the rotating body 120 is rotatably installed inside the housing body 111, and the water supply pipe 130 is fixedly installed inside the housing body 111. The water supply pipe 130 extends into the air outlet passage 1202 of the rotating body 120 to supply water to the inner peripheral wall 122 of the rotating body 120. It should be noted that the water supply pipe 130 is stationary relative to the rotating body 120 and does not rotate with the rotating body 120.

[0045] Please refer to Figure 4 and Figure 5 , when the air purification module 100 is working, the rotating body 120 rotates at a high speed, and the flow path of the air is opposite to the flow path of the water droplets, that is, the air and the water droplets flow in opposite directions to achieve collision flushing and purification. Among them, the flow path of the air is as follows: the rotating body 120 rotates at a high speed, and a negative pressure is formed in the air outlet passage 1202. Under the internal and external pressure difference, the air enters the inside of the housing 110 from the air inlet 1101; then it passes through the air inlet passage 1201 and flows into the air outlet passage 1202; finally, it blows from the air outlet passage 1202 to the air outlet 1102 and is blown out from the air outlet 1102. During the process of the air passing through the air inlet passage 1201, the air first passes through the outer peripheral wall 123 and enters the inside of the rotating body 120, flows from the outside to the inside inside the rotating body 120, and then passes through the inner peripheral wall 122 and flows into the air outlet passage 1202.

[0046] The flow path of the water is as follows: the water supply pipe 130 supplies water to the inner peripheral wall 122 of the rotating body 120. When the rotating body 120 rotates at a high speed, the water on the inner peripheral wall 122 is thrown out radially from the inside to the outside under the centrifugal force, and the thrown water droplets are refined into water beads with smaller particle sizes. During this water throwing process, the outward moving water beads collide with the inward flowing air on the air inlet passage 1201 inside the rotating body 120 to achieve air purification by supergravity water throwing. For example, fine particulate matter, pollen, etc. in the air are settled, or floating microorganisms, bacteria, volatile organic compounds, etc. (such as formaldehyde, benzene, TOVC) are dissolved in water and carried away.

[0047] In the technical solution of the present invention, an air outlet duct 1202 is provided on the rotating body 120, which extends along its rotation axis and communicates with the air outlet 1102. An air inlet duct 1201 is formed on the rotating body 120 for air to flow from the outer peripheral wall 123 through the inner peripheral wall 122 into the air outlet duct 1202, so as to connect the air inlet 1101 and the air outlet duct 1202. The water supply pipe 130 provided in the air outlet duct 1202 supplies water to the inner peripheral wall 122. When the rotating body 120 rotates, the rotating body 120 throws the water out from the outer peripheral wall 123, so that the water droplets thrown out from the inside to the outside collide with the air flowing from the outside to the inside. During this collision process, not only is the collision contact time long, but the water droplet diameter is extremely refined, so that the water droplets are in full contact with the air, effectively improving the purification efficiency.

[0048] Please refer to Figure 4 and Figure 5 , based on the above embodiments, theoretically speaking, the air outlet duct 1202 can be arranged to extend horizontally or vertically (i.e., up and down). In this embodiment, the air outlet duct 1202 extends along the up and down direction of the air purification module 100, so that the air flows from bottom to top.

[0049] Based on this, the air inlet 1101 is arranged at the lower part of the housing 110 and is connected to the lower end of the air outlet duct 1202 through the air inlet duct 1201; the air outlet 1102 is arranged at the upper part of the housing 110 and is connected to the upper end of the air outlet duct 1202. Such a design can make full use of the longitudinal space of the air treatment module and reduce the lateral size of the air treatment module.

[0050] Please refer to Figure 4 and Figure 5 , the air treatment module further includes a purification fan 150, and the purification fan 150 is located between the air outlet 1102 and the air outlet duct 1202. Specifically, the purification fan 150 is installed on the housing cover 113. When the purification fan 150 works, it can form a large negative pressure in the air outlet duct 1202, thereby driving the air to accelerate from the air inlet duct 1201 into the air outlet duct 1202 and blowing upward through the air outlet duct 1202 to the air outlet 1102.

[0051] Please refer to Figure 4 and Figure 5 , the air purification module 100 further includes a water supply tank (not shown), the water supply tank is located below the rotating body 120, and the water supply tank is connected to the water supply pipe 130 through a water pipe to serve as the 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 housing 110. The water supply tank provides sufficient water for the water supply pipe 130. Of course, the water source of the water supply pipe 130 can also be provided by the user.

[0052] Please refer toFigure 4 and Figure 5 For the water supply pipe 130, the extending direction of the water supply pipe 130 is the same as that of the air outlet air path 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. Considering that water flows downward under the action of its gravity, the water inlet 131 of the water supply pipe 130 is arranged at the upper end of the water supply pipe 130 herein.

[0053] The peripheral wall of the water supply pipe 130 is penetrated with water spraying holes (not shown). Among the plurality of water spraying holes, some of the water spraying holes are arranged at intervals along the length direction of the water supply pipe 130, and the other part of the water spraying holes are arranged at intervals along the circumferential direction of the water supply pipe 130. The rotating body 120 is penetrated with water throwing holes (not shown), and the water spraying holes are communicated with the water throwing holes.

[0054] When the rotating body 120 throws water, the water supply pipe 130 sprays water through the plurality of water spraying holes to the water throwing holes on the inner peripheral wall 122. The rotating body 120 rotates at a high speed to throw out the water in the water throwing holes, and the thrown water is thrown out tangentially along the outer peripheral wall 123 to enhance the purification effect.

[0055] As for the fixing manner of the water supply pipe 130, the water supply pipe 130 can be directly connected and fixed to the housing 110 by itself, or can be connected and fixed to the housing 110 through a connecting member. There is no limitation herein, and there will be a detailed introduction later.

[0056] Please refer to Figure 4 and Figure 5 In an embodiment, to facilitate guiding the air in the air outlet air path 1202 to the air outlet 1102, optionally, the air purification module 100 further includes a wind guiding cylinder 140 fixedly connected to the housing 110. The wind guiding cylinder 140 extends into the air outlet air path 1202 to communicate the air outlet air path 1202 and the air outlet 1102.

[0057] Since the water supply pipe 130 needs to be fixedly installed in the air outlet air path 1202, and the wind guiding cylinder 140 is located in the air outlet air path 1202 and is fixedly connected to the housing 110, therefore, the water supply pipe 130 can be arranged on the side wall of the wind guiding cylinder 140 to simplify the fixing structure. Optionally, the water supply pipe 130 is arranged around the wind guiding cylinder 140 so that the water supply pipe 130 uniformly sprays water along the circumferential direction of the wind guiding cylinder 140 to the inner peripheral wall 122 of the rotating body 120.

[0058] Please refer to Figure 2 、 Figure 4 and Figure 5, Further, the water supply pipe 130 and the air guide cylinder 140 are integrally formed. The side wall of the air guide cylinder 140 is hollow, so that the cylinder wall of the air guide cylinder 140 forms the water supply pipe 130. Such a design can reduce the number of manufacturing parts and processes and improve production efficiency. Here, for the convenience of fixing the air guide cylinder 140, the upper end of the air guide cylinder 140 extends into the air induction shell 112 and is fixedly connected to the air induction shell 112.

[0059] Please continue to refer to Figure 4 , For the rotating body 120, the rotating body 120 is driven to rotate by a driving device. The driving device can be the structure of the air conditioner indoor unit 200 itself or be driven by linkage of the motor of the purification fan 150. In this embodiment, the air purification module 100 further includes a driving device (not shown). The driving device is installed on the housing 110 and is connected to the rotating body 120 to drive the rotating body 120 to rotate along the rotation axis.

[0060] In one embodiment, for the convenience of installing the rotating body 120, the air purification module 100 further includes a rotating support frame 170 rotatably installed in the housing 110. The rotating body 120 is installed on the rotating support frame 170 to be driven to rotate by the rotating support frame 170.

[0061] Specifically, a rotating shaft (not shown) is provided at the bottom of the rotating support frame 170. The rotating shaft is installed on the water supply tank through a bearing. The driving device is connected to the rotating shaft to drive the rotating support frame 170 to drive the rotating body 120 to rotate. By driving the rotating body 120 to rotate through the rotating support frame 170, the gravity of the rotating body 120 is supported, the load bearing of the rotating body 120 is reduced, and the rotating body 120 is not easily deformed or thrown out under high-speed rotation.

[0062] Regarding the specific structure of the rotating body 120, the rotating body 120 should be a pore structure having ventilation pores and water-throwing pores. The ventilation pores and the water-throwing pores are communicating pores. These pores can be holes, strip-shaped capillary pores, or gaps, etc. Therefore, the rotating body 120 can be formed of a porous material, such as a multi-layer mesh structure. The rotating body 120 can also be a hollow cylindrical structure, and pores (such as round holes, capillary pores, mesh holes, etc.) are correspondingly formed in its inner peripheral wall 122 and outer peripheral wall 123. Some pores are used for ventilation, and some pores are used for throwing out the water supplied by the water supply pipe 130.

[0063] Here, in order to form the air inlet air path 1201, a plurality of air inlet holes are provided on the outer peripheral wall 123, and a plurality of air outlet holes 1221 are provided on the inner peripheral wall 122. The air inlet holes and the air outlet holes 1221 are communicated to form the air inlet air path 1201. There can be various choices for the positions of the air inlet holes and the air outlet holes 1221. Four examples are listed below:

[0064] Please refer toFigure 6 , in the first embodiment, the air outlet hole 1221 is located in a portion of the inner peripheral wall 122 close to the bottom wall 121, and the water supply pipe 130 supplies water to a portion of the inner peripheral wall 122 above the air outlet hole 1221. At this time, the plurality of air inlet holes may be arranged at intervals on the entire wall surface of the outer peripheral wall 123. That is to say, the entire wall surface of the outer peripheral wall 123 forms an air inlet surface, and air enters the interior of the rotating body 120 through the outer peripheral wall 123. During this process, the air collides with the water droplets moving outward in the radial direction of the rotating body 120 first, and then is squeezed and flows downward to the air outlet hole 1221, and flows into the air outlet duct through the air outlet hole 1221.

[0065] Please refer to Figure 7 , in the second embodiment, the difference from the above first embodiment is that the plurality of air inlet holes are all arranged in the middle and / or upper part of the outer peripheral wall 123. That is to say, only the middle and / or upper wall surface of the outer peripheral wall 123 forms an air inlet surface, and air enters the interior of the rotating body 120 through this air inlet surface. During this process, the air collides with the water droplets moving outward in the radial direction of the rotating body 120 first, and then is squeezed and flows downward to the air outlet hole 1221, and flows into the air outlet duct through the air outlet hole 1221. The path of the air flowing downward is effectively extended, and the purification effect can be enhanced.

[0066] Please refer to Figure 8 , in the third embodiment, the difference from the above first embodiment is that the rotating body 120 further includes a top wall 124, the air outlet hole 1221 is located in a portion of the inner peripheral wall 122 close to the top wall 124, and the water supply pipe 130 supplies water to a portion of the inner peripheral wall 122 below the air outlet hole 1221. At this time, the plurality of air inlet holes may be arranged at intervals on the entire wall surface of the outer peripheral wall 123. Similarly, the entire wall surface of the outer peripheral wall 123 forms an air inlet surface, and air enters the interior of the rotating body 120 through the outer peripheral wall 123. During this process, the air collides with the water droplets moving outward in the radial direction of the rotating body 120 first, and then floats upward by its own buoyancy to the air outlet hole 1221, and flows into the air outlet duct through the air outlet hole 1221.

[0067] Please refer to Figure 9 , in the fourth embodiment, the difference from the above third embodiment is that the plurality of air inlet holes are arranged in the middle and / or lower part of the outer peripheral wall 123. That is to say, only the middle and / or lower wall surface of the outer peripheral wall 123 forms an air inlet surface, and air enters the interior of the rotating body 120 through this air inlet surface. During this process, the air collides with the water droplets moving outward in the radial direction of the rotating body 120 first, and then floats upward by its own buoyancy to the air outlet, and flows into the air outlet duct through the air outlet hole 1221. The path of the air flowing downward is effectively extended, and the purification effect can be enhanced.

[0068] Based on any of the above embodiments, considering the collision purification of air and water droplets within the rotating body 120, in order to enhance the purification effect, a water spraying structure (not shown) can also be provided between the inner peripheral wall 122 and the outer peripheral wall 123 to break up and refine the water supplied to the rotating body 120 by the water supply pipe 130, so that the particle size of the water droplets is further reduced, enabling full contact with air and thereby improving the purification efficiency.

[0069] As for the water spraying structure, the water spraying structure can be water spraying plates stacked in upper and lower layers. The water spraying plates have a plurality of through holes that allow both air flow and water droplets to pass through. When the water droplets pass through, they are broken up and refined. The water spraying structure can also be water spraying rods arranged in a crisscross pattern. When the water droplets thrown out and moving outward within the rotating body 120 hit the water spraying rods, the water droplets are broken up into numerous water particles. In addition, the water spraying structure can also be a perforated mesh, which has numerous small holes that can also break up the water droplets into numerous water particles.

[0070] The present invention also provides an air conditioner indoor unit 200. The air conditioner indoor unit 200 includes a housing and an air purification module 100. Among them, the housing 210 is provided with a purification air inlet 211 and a purification air outlet 212. The specific structure of the air purification module refers to the above embodiments. Since this air conditioner indoor unit adopts all the technical solutions of the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.
