Description

Technical Field

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

[0002] The purification scheme adopted by air conditioners in the prior art is mainly to install a purification module at the air outlet or air inlet of the air conditioner. There are several main methods for purifying air: (1) using photocatalysts to remove formaldehyde; (2) using electrostatic dust removal technology; (3) using HEPA filters to remove PM2.5. (4) filtering and purification with ordinary filter cartridges; (5) negative ion adsorption; (6) activated carbon adsorption. Currently, air conditioners have water washing functions. However, the mainstream purification methods of air conditioner products on the market currently have the following problems: 1. Secondary pollution occurs after the activated carbon is saturated; 2. The catalyst becomes ineffective after being covered by dust; 3. The CADR decreases after the filter is blocked, and secondary pollution precipitates; 4. The filter is frequently replaced, which increases costs; 5. Incomplete photocatalytic catalysis produces toxic substances; 6. Electrostatic dust removal technology produces ozone problems; 7. Incomplete HEPA cleaning reduces cleaning efficiency, etc.

[0003] To this end, a manufacturer has developed an air purification module, which includes a shell and a rotating body. The rotating body is rotatably arranged in the shell, so that when water is sprayed on the rotating body, the water is thrown out through rotation to generate water particles, which combine with dust in the air to achieve the purpose of purifying the air. However, the number of water particles generated by a single rotating body is limited, and the air purification effect is limited. If the air purification effect is to be further improved, when a single rotating body is used to rotate, the rotating body's speed is too fast, which will lead to poor equipment stability. If the rotating body's speed is controlled for equipment stability, the purification effect cannot be improved.

[0047] 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

[0048] 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.

[0049] 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.

[0050] Please refer to Figures 2 to 6 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 inlet at one end and air outlet at the other end. Of course, in other embodiments, the module air outlet 112 may also be arranged on the peripheral side of the housing 110. It should be noted that the directional indications involved in the embodiments of the present invention (such as up, down, left, right, front, back...) 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 indication will also change accordingly.

[0051] In one embodiment, please refer to Figure 6 , the lower end of the shell 110 expands outward to form a step, and the module air inlet 111 is opened on the peripheral side of the lower end of the shell. In this way, the phenomenon of water droplets spraying from the air inlet can be reduced, and the step can receive a small amount of sprayed water droplets to prevent water droplets from being splashed onto the floor. In another embodiment, the upper end of the shell 110 shrinks upward to form a step-shaped boss 170, and the module air outlet 112 is opened on the peripheral side of the boss 170. In this way, a water baffle extending laterally is formed at the upper end of the shell to block water droplets splashing upward to reduce the phenomenon of water droplets spraying from the module air outlet 112. The above settings of the module air inlet 111 and the module air outlet 112 can be implemented in combination.

[0052] Please refer to Figure 3 and Figure 5 , multiple rotating bodies 120 are rotatably arranged in the purification air duct 113. When water is sprayed on the rotating body 120, the water is thrown out by rotation, that is, the rotating body 120 is used to rotate the water out when it rotates around its rotation axis. The thrown water contacts the air in the purification air duct 113 and absorbs particles in the air, thereby purifying the air. Specifically, in this embodiment, multiple rotating bodies 120 are provided. Multiple rotating bodies 120 can be arranged in the same purification chamber, or they can be correspondingly arranged in multiple relatively separated purification chambers.

[0053] In the technical solution provided by the present invention, the water thrown out by each rotating body 120 forms water particles, which come into contact with the air in the purified air duct 113, adsorb the particles in the air, and thus purify the air. Using multiple rotating bodies 120 to work simultaneously can produce more water particles, thereby more thoroughly adsorbing the particles in the air. Compared with the prior art, without further increasing the rotation speed of the rotating body 120, by setting multiple rotating bodies 120, the air purification effect is further enhanced, which is beneficial to the stability of the air purification module 100.

[0054] There are many ways to arrange the multiple rotating bodies 120, such as coaxial arrangement or side by side arrangement. Optionally, the multiple rotating bodies 120 are arranged side by side at intervals, so that the structure of the air purification module 100 is more reasonable and the space occupied by the air purification module is reduced.

[0055] In one embodiment, the purification air duct 113 includes a plurality of connected purification chambers, so that air flows in from the module air inlet 111, flows through the plurality of purification chambers in sequence, and flows out from the module air outlet 112, and the plurality of rotating bodies 120 are correspondingly arranged in the plurality of purification chambers. In this way, the air entering the purification air duct 113 collides with the water particles thrown out by the rotating body 120 in the first purification chamber, and is merged into the water particles, thereby achieving purification of the air, and the harmful particles that have not been purified continue to flow to the next purification chamber, and are further purified by the next rotating body 120, thereby achieving multiple water washing of the air, and the air flows through each purification chamber in sequence, the purification path is lengthened, the purification time is lengthened, and thus the purification effect is improved.

[0056] Preferably, there are two rotating bodies 120 to achieve double water washing of the air entering the purification air duct 113, further improving the air purification effect. At the same time, the number of rotating bodies 120 can be more reasonable to simplify the internal structure of the air purification module 100 and reduce the space occupied by the air purification module 100. The two rotating bodies 120 can be arranged at intervals along the axial direction or along the radial direction, and can be arranged in the same cavity or in two relatively separated purification cavities.

[0057] In the first embodiment, see Figures 2 to 4 , the number of rotating bodies 120 is two. A partition 1101 is provided in the shell 110, and the partition 1101 divides the purification air duct 113 into a first purification chamber 1131 and a second purification chamber 1132. The first purification chamber 1131 is connected to the second purification chamber 1132 (for example, the top or bottom of the two can be connected, or the middle can be partially connected), one of the rotating bodies 120 is located in the first purification chamber 1131, and the other rotating body 120 is located in the second purification chamber 1132. In this embodiment, the air enters the first purification chamber 214 from the air inlet for purification and water washing, and then enters the second purification chamber 215 for secondary purification. Therefore, the flow path of the air in the purification air duct 113 is standardized by the partition 1101, ensuring that the air entering the purification air duct 113 flows through the first purification chamber 1131 and the second purification chamber 1132 in sequence, the purification path is lengthened, the purification time is lengthened, and the purification effect is improved.

[0058] In actual application, the tops of the first purification chamber 1131 and the second purification chamber 1132 are connected, and the module air inlet 111 and the module air outlet 112 are respectively arranged at the lower ends of the first purification chamber 1131 and the second purification chamber 1132. In this way, the air entering the purification air duct 113 fully flows through the two rotating bodies 120 from bottom to top and then downward, and the upward flowing air fully contacts the falling water particles, further enhancing the air purification effect.

[0059] In order to promote the flow of air in the purification air duct 113, a fan 140 may be provided. The purification air duct 113 forms an air passage cavity 1130 at the connection between the first purification cavity 1131 and the second purification cavity 1132, and the fan 140 is provided at the connection between the first purification cavity 1131 and the second purification cavity 1132 to reduce the resistance of the air flowing at the connection between the two purification cavities, accelerate the air flow in the purification air duct 113, and improve the air outlet efficiency.

[0060] In the second embodiment, see Figure 5 and Figure 6 , multiple rotating bodies are located in the same purification chamber. In this embodiment, "located in the same purification chamber" means that multiple rotating bodies 120 are arranged in the purification chamber enclosed by the shell 110, and there is basically no barrier between adjacent rotating bodies, so that the water particles thrown out by adjacent rotating bodies 120 can collide with each other. Taking the number of rotating bodies 120 as two as an example, the two rotating bodies 120 are located in the same purification chamber, the module air inlet 111 is arranged near one of the rotating bodies 120, and the module air outlet 112 is arranged near the other rotating body 120. In this way, the two rotating bodies 120 can work at the same time to produce more water particles, and the water particles collide with each other to produce more tiny water particles that are fully in contact with the air, and the air flows through the two rotating bodies 120 in the purification air duct 113 in turn, lengthening the purification path, thereby achieving a better purification effect. Preferably, the two rotating bodies 120 are arranged side by side and spaced apart. When the air purification module 100 is working, the two rotating bodies 120 rotate in opposite directions, thereby further strengthening the collision between the water particles, making the water particles more fully contact with the air, and enhancing the cleaning effect of the water particles. It can be understood that the specific number of rotating bodies 120 can be adjusted as needed, and when the number of rotating bodies 120 exceeds two, the above technical effect can also be achieved.

[0061] In one embodiment, the air purification module 100 further includes a driving device 130, which is drivingly connected to the plurality of rotating bodies 120 to drive the rotating bodies 120 to rotate along their rotation axes, so that the rotating bodies 120 generate a large centrifugal force, and the water flow is thrown outward, so that the water particles are in contact with the air in the purification air duct 113, so that the air is purified and humidified. Specifically, the driving device can be a motor installed on the inner wall of the housing, and is key-connected to each rotating body 120.

[0062] In one embodiment, the rotation direction and / or rotation speed of the plurality of rotating bodies are adjustable. For example, the rotation speed of each rotating body 120 may have three gears: high speed, medium speed, and low speed, and the rotation direction of each rotating body 120 may have forward and reverse directions. In this way, when multiple rotating bodies 120 are set to rotate simultaneously, the water washing efficiency can be improved, and when different rotation speeds are selected, multi-stage adjustment control can be formed. The combination of different rotation speeds of the rotating body 120 increases the control level of the air purification module 100, and the user has more control options and can adapt to more scenarios. For example, setting a single rotating body 120 to work in silent mode, the noise of a single rotating body 120 is small, setting multiple rotating bodies 120 to work in enhanced mode, and the water washing effect of multiple rotating bodies 120 is better.

[0063] Furthermore, in the present embodiment, when the air purification module 100 is working, the linear speed of the outer edge of the rotating body 120 is 10m / s to 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.

[0064] Furthermore, 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.

[0065] There are many methods to spray water onto the rotating body 120. For example, a water source disposed above the rotating body 120 may spray water onto the rotating body 120, or a water pipe may be disposed to transport water into the 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 water supply channel is adapted to be connected to the water source. A water-throwing channel 122 connected to the water supply channel is provided on the circumference of the rotating body 120. Specifically, the water-throwing channel 122 may be a fine mesh, and the water entering the water supply channel is sprayed out from the fine mesh to form tiny water particles, which are ejected along the tangential direction of the rotating body 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.

[0066] In another embodiment, see Figure 4, a water supply pipe installation space 121 extending along the rotation axis is formed in the rotating body 120, and the air purification module also includes a water supply pipe 152, which is suitable for communicating with a water source, and the water supply pipe 152 is inserted in the water supply pipe installation space 121, and an overflow hole 1520 is provided on the peripheral wall of the water supply pipe 152, and a water-throwing channel 122 communicating with the overflow hole 1520 is provided on the peripheral side of the rotating body 120. Preferably, the diameter of the overflow hole 1520 is 1 mm, and water is ejected from the overflow hole 1520 at a high speed to form fine water droplets. The ejected water droplets are further subdivided through the external water-throwing channel 122 to become even smaller water particles, and are ejected along the tangential direction of the rotating body 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. In this way, a better purification effect can be achieved.

[0067] Furthermore, the water source may be an external water source or an internal water source provided in the air purification module 100. For example, it may be a water tank 150 and a water pump 151 provided at the bottom of the housing 110, the water inlet of the water pump 151 being connected to the water tank 150, and the water outlet of the water pump 151 being connected to the water supply channel or the water supply pipe 152. In this way, the water in the water tank 150 can be transported to the inside of the rotating body 120 through the water pump 151, and the water pressure can be increased by the water pump, so that the water is ejected from the inside of the rotating body 120 at a high speed, achieving a better refinement effect and generating water particles at a higher speed.

[0068] Furthermore, there are many ways to rotatably install the rotating body 120. In one implementation, one end of each rotating body 120 is rotatably connected to the inner wall of the housing 110, and the other end of each rotating body 120 is rotatably installed on the water supply pipe 152. Specifically, both ends of the rotating body 120 are fixed by bearings, so that each rotating body 120 is stably supported and is not easy to shake even in the case of high-speed rotation.

[0069] In one embodiment, a negative ion generator 160 is provided at the air inlet. The negative ions generated by the negative ion generator 160 gather dust in the air to form large dust particles. The dust particles come into contact with high-speed water particles and are washed away to achieve a better purification effect.

[0070] The present invention also proposes an air-conditioning indoor unit, which 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-conditioning 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-conditioning indoor unit also includes a heat exchanger and a heat exchange fan. The casing 200 extends in the up and down direction, and 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.

[0071] 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.

[0072] 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.

[0073] 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 151 transports the water in the water tank 150 to the water supply channel or water supply pipe 152, and sprays the water around the rotating body 120; the rotating body 120 rotates under the drive of the driving device 130, and the high-speed rotating body 120 generates centrifugal force to throw the water around, 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.

[0074] 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.

[0075] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
