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 photocatalyst to remove formaldehyde; (2) using electrostatic dust removal technology; (3) using HEPA screen 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 have the following main problems: 1. Secondary pollution occurs after the activated carbon is saturated; 2. The catalyst becomes ineffective after being covered by dust; 3. CADR decreases after the screen is blocked, and secondary pollution precipitates; 4. The screen needs to be replaced frequently, 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 housing and a rotating body. The rotating body is rotatably arranged in the housing, so that when water is sprayed onto the rotating body, 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. However, the number of water particles generated by a single rotating body is limited, the air purification effect is limited, and the water particles in the housing are unevenly distributed, resulting in poor purification effect.

[0050] 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

[0051] 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.

[0052] 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.

[0053] Please refer to Figures 2 to 5 Specifically, the air purification module 100 in the present invention includes a shell 110 and a rotating body. 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 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 sealed ends. 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.

[0054] Please refer to Figures 2 to 5, a plurality of rotating bodies 120 are rotatably disposed in the purification air duct 113. When water is sprayed onto the rotating body, the water is thrown outward by rotation, that is, the rotating body is used to rotate the water outward 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, a plurality of rotating bodies are provided, and the plurality of rotating bodies are arranged in sequence in the first direction, and the rotation axis of each rotating body extends along the first direction.

[0055] 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 to work simultaneously can produce more water particles, so that the adsorption of particles in the air is more thorough. At the same time, multiple rotating bodies are arranged in sequence in the same direction, and the rotating shafts of each rotating body extend along this direction. Each rotating body generates disturbances to the air, which is beneficial to the uniform distribution of water particles in the purified air duct 113. Compared with the prior art, without further increasing the rotation speed of the rotating body 120, by setting multiple rotating bodies, the air purification effect is further enhanced, which is beneficial to the stability of the air purification module 100.

[0056] In one embodiment, when the air purification module 100 is working, at least two adjacent rotating bodies among the multiple rotating bodies have different rotation speeds. In this way, different rotating bodies have different rotation speeds and throw out different water particle sizes, so that particles of different sizes can be absorbed, which is beneficial for purifying and absorbing particles of different sizes in the air, thereby improving the purification effect.

[0057] In one embodiment, when the air purification module 100 is working, at least two adjacent rotating bodies among the multiple rotating bodies rotate in opposite directions. The adjacent rotating bodies rotate in opposite directions, providing a great shear force, so that the airflow in the purification air duct 113 is cut, thereby generating strong turbulence. At this time, the turbulence intensity of the gas is enhanced, and the renewal speed of the airflow surface is increased, which is conducive to the uniform distribution of air and water particles in the purification air duct 113, thereby improving the air purification effect.

[0058] In one embodiment, the rotation axes of the multiple rotating bodies extend coaxially, which is more conducive to the fixed installation of the rotating bodies and saves space.

[0059] Preferably, the number of the rotating bodies is two, so as to realize double water washing of the air entering the purification air duct 113, and further improve the air purification effect. At the same time, the number of the rotating bodies can be made more reasonable, so as to simplify the internal structure of the air purification module 100 and reduce the occupied space of the air purification module 100. In this embodiment, the rotating axes of the first rotating body 121 and the second rotating body 122 extend up and down, and the first rotating body 121 is arranged above the second rotating body 122. In this way, the first rotating body 121 and the second rotating body 122 are arranged in the up and down direction, which is conducive to the installation and arrangement of the rotating bodies.

[0060] Based on the previous embodiment, further, please refer to Figures 3 to 5 The air purification module 100 further includes a first driving device 131 and a second driving device 132. The first driving device 131 is connected to the first rotating body 121 to drive the first rotating body 121 to rotate. The second driving device 132 is connected to the second rotating body 122 to drive the second rotating body 122 to rotate. In this way, the two rotating bodies are driven by separate driving devices, respectively, so that the rotation speed and direction of each rotating body can be controlled separately.

[0061] The first driving device 131 and the second driving device 132 can be installed in various ways, as long as they can achieve the driving connection between the first rotating body 121 and the second rotating body 122. Figure 6 The first driving device 131 is installed above the first rotating body 121 through the first motor bracket 141. The outer periphery of the first motor bracket 141 is connected to the housing 110. The central area of ​​the first motor bracket 141 is provided with a first driving mounting portion 1410. The first driving mounting portion 1410 has a mounting cavity. The first driving device 131 and the first bearing 171 are arranged in the mounting cavity along the vertical direction. The driving end 130 of the first driving device 131 is downwardly penetrated through the first bearing 171 and is drivingly connected to the upper end of the first rotating body 121. Only torque is transmitted between the first driving device 131 and the first rotating body 121. At the same time, the first rotating body 121 is supported by the bearing, so that it is more firmly supported to enhance the stability of the rotating body.

[0062] In one embodiment, please refer to Figure 7The second driving device 132 is installed below the second rotating body 122 through the second motor bracket 142. The outer periphery of the second motor bracket 142 is connected to the housing 110. The central area of ​​the second motor bracket 142 is provided with a second driving mounting portion 1420. The second driving mounting portion 1420 has a mounting cavity. The mounting cavity is provided with a second bearing 172 and a second driving device 132 in the vertical direction. The driving end 130 of the second driving device 132 is upwardly penetrated through the second bearing 172 and is drivingly connected to the lower end of the second rotating body 122. Only torque is transmitted between the second driving device 132 and the second rotating body 122. At the same time, the second rotating body 122 is supported by the bearing, so that it is more firmly supported to enhance the stability of the rotating body.

[0063] In one embodiment, please refer to Figure 8 The lower end of the second rotating body 122 is provided with a water baffle 123 extending outward from the outer circumference of the second rotating body 122, and the water baffle 123 is arranged above the second bearing 172 at intervals. Water particles are blocked by the water baffle 123 and do not enter the bearing and the driving device below, thereby preventing the electromechanical components from being corroded by liquid and affecting the service life of the air purification module 100.

[0064] There are many ways to supply water to the first rotating body 121 and the second rotating body 122. For example, a water supply device disposed above each rotating body can spray water downward on the rotating body, or water can be directly supplied to the inside of the rotating body. Figure 3 and Figure 8 The first rotating body 121 and the second rotating body 122 are respectively formed with water supply pipe installation spaces 124 extending up and down. The air purification module 100 also includes a water supply pipe 152, which is suitable for communicating with a water source. The water supply pipe 152 is inserted into the water supply pipe installation spaces 124 of the first rotating body 121 and the second rotating body 122. The peripheral wall of the water supply pipe 152 is provided with an overflow hole 153, and the peripheral sides of the first rotating body 121 and the second rotating body 122 are provided with a water-throwing channel connected with the overflow hole 153. The water transported to the water supply pipe 152 is ejected from the overflow hole 153 at a high speed to form fine water droplets. The ejected water droplets are thrown out through the external water-throwing channel, and are further subdivided due to the action of centrifugal force to become even smaller water particles, and are ejected along the tangential direction of the rotating body under the rotation of the rotating body. The dust in the air contacts and fuses with the high-speed water particles, thereby purifying the air.

[0065] On the basis of the previous embodiment, further, the first rotating body 121 has a first opening 1210 at the lower end thereof connected to the water supply pipe installation space 124, and the second rotating body 122 has a second opening 1220 at the upper end thereof connected to the water supply pipe installation space 124, the first opening 1210 and the second opening 1220 are arranged opposite to each other up and down, and a gap is formed between the first opening 1210 and the second opening 1220, the upper end of the water supply pipe 152 is inserted into the water supply pipe installation space 124 of the first rotating body 121 through the first opening 1210, and the lower end of the water supply pipe 152 is inserted into the water supply pipe installation space 124 of the second rotating body 122 through the second opening 1220, and the water supply pipe 152 is provided with a water delivery channel 154 at the gap, and the water delivery channel 154 is suitable for being connected to a water source. Through the above structure, the same water supply pipe 152 can simultaneously supply water to the first rotating body 121 and the second rotating body 122, the structure is simpler, and the water output of the two rotating bodies is more uniform, thereby improving the air purification effect.

[0066] The water source may be an external water source or an internal water source provided in the air purification module 100. For example, in the present embodiment, 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 delivery channel 154. In this way, the water in the water tank 150 can be transported to the inside of the first rotating body 121 and the second rotating body 122 through the water pump 151, and the water pressure can be increased through the water pump 151, so that the water is ejected from the inside of the rotating body at a high speed, achieving a better refinement effect and generating water particles at a higher speed.

[0067] In a preferred embodiment, the water outlet of the water pump 151 is connected to the water delivery channel 154 through the water delivery pipe 155, and the middle section of the water delivery pipe 155 is located outside the housing 110. In this way, the water delivery pipe 155 is prevented from affecting the rotation of the first rotating body 121 and the second rotating body 122 in the purification air duct 113, which is convenient for installation and maintenance.

[0068] In one embodiment, in order to fix the water supply pipe 152, please refer to Fig. 9 A water supply pipe mounting frame 160 is also provided in the housing 110. The water supply pipe mounting frame 160 includes a mounting ring 161. The mounting ring 161 is provided at the gap between the first opening 1210 and the second opening 1220, and is used to sleeve and support the water supply pipe 152. A support member 162 extending radially outwardly along the water supply pipe 152 is provided on the outer periphery of the mounting ring 161. The outer end of the support member 162 is supported on the housing 110. The water supply pipe 152 is supported stably in this way, and it is ensured that the water supply pipe 152 extends up and down, and will not affect the rotation of the rotating body when the rotating body rotates.

[0069] Preferably, a third bearing 173 is sleeved in the mounting ring 161, and the third bearing 173 is disposed at the upper end of the second rotating body 122. After the water supply pipe 152 is downwardly passed through the third bearing 173, it is inserted into the water supply pipe installation space 124 of the second rotating body 122. In this way, the mounting structure is simpler, and effective support is provided for the second rotating body 122, making the second rotating body 122 more stable.

[0070] In one embodiment, a filter screen 125 is provided on the circumference of each rotating body, and the filter screen 125 extends radially outward from the outer periphery of each rotating body. The filter screen 125 is used to receive water sprayed onto the rotating body, so that the water on the filter screen 125 performs centrifugal motion during high-speed rotation, thereby forming a large number of tiny water particles on the filter screen 125 mesh disk, 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. Preferably, the filter screen 1251 is provided with multiple layers, and the multiple layers of the filter screen 125 are arranged on the rotating body at intervals along the axial direction of each rotating body, thereby increasing the number of water particles to improve the purification effect.

[0071] In one embodiment, when the air purification module 100 is working, the linear speed of the outer edge of the rotating body is 10 m / s~45 m / s. When the linear speed of the outer edge of the rotating body is too small, the speed of the water thrown out by the rotation is small, and the purification effect on the air is poor. When the linear speed of the outer edge of the rotating body is too large, the energy consumption of the rotating body is large and the noise generated is large, and continuing to increase the linear speed of the outer edge of the rotating body has little effect on improving the air purification effect.

[0072] On the basis of the previous embodiment, preferably, when the air purification module 100 is working, the linear speed of the outer edge of the rotating body is 20 m / s to 30 m / s. At this time, the rotating body has the advantages of good purification effect, reasonable energy consumption and low noise.

[0073] In one embodiment, a module air inlet 111 and a module air outlet 112 are provided on the housing 110, and the purification air duct 113 is connected to the module air inlet 111 and the module air outlet 112, and the module air inlet 111 and the module air outlet 112 are arranged at both ends of the purification air duct 113 in the first direction. In this way, the air flow flowing through the purification air duct 113 flows along the first direction, and forms a countercurrent between the water particles thrown out by the rotating body in the purification air duct 113, thereby improving the fusion effect between the water particles and the air and improving the purification effect. Preferably, the air purification module 100 also includes a fan 140, which is used to drive the air to flow in from the air inlet and out from the air outlet, thereby increasing the air circulation speed in the purification air duct 113 and improving the air purification efficiency.

[0074] The present invention also proposes an air-conditioning indoor unit, which includes a housing 200 and an air purification module 100. The specific structure of the air purification module 100 is referred 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 housing 200 extends in the up and down direction, and the housing 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.

[0075] 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.

[0076] 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 shell). 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 it can avoid other parts on the inner wall of the housing 200 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.

[0077] 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 pipe 152, and sprays the water around the rotating body; the rotating body rotates under the drive of multiple driving devices, and the high-speed rotating body generates centrifugal force to throw the water around, 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 113, 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 module air outlet 112, and finally blows out from the purification air outlet 230 on the housing 200.

[0078] 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.

[0079] 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.
