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] Traditional air conditioners use HEPA nets for dust and haze removal. The fan's suction circulates indoor air through the HEPA net to remove small solid particles. However, while the HEPA net removes small PM2.5 solid particles in the air, it is often easy to accumulate dust. Dust clogs the HEPA net, causing the HEPA net to lose its filtering effect quickly, and the HEPA net needs to be replaced frequently, resulting in increased costs. Summary of the invention

[0003] The main purpose of the present invention is to provide an air purification module, which aims to effectively purify the air while reducing the increase in costs.

[0004] To achieve the above object, the present invention provides an air purification module, the air purification module comprising:

[0005] A housing is formed with a purification air duct; and

[0006] A rotating body is rotatably arranged in the purification air duct. When water is sprayed onto the rotating body, the rotating body throws the water outward by rotating. The rotating body has a rotation axis. The rotating body has a first point and a second point located on its outer circumference. The distance from the first point to the rotation axis is different from the distance from the second point to the rotation axis.

[0007] Optionally, the rotating body has two ends distributed along the rotation axis, and the distance between the outer circumference of the ends of the rotating body and the rotation axis is smaller than the distance between the outer circumference of the middle part of the rotating body and the rotation axis.

[0008] Optionally, the outer circumference of the rotating body gradually decreases from the middle to the end.

[0009] Optionally, the rotating body is spherical or ellipsoidal.

[0010] Optionally, the rotating body has two ends distributed along the rotation axis, and the distance between the outer circumference of the ends of the rotating body and the rotation axis is greater than the distance between the outer circumference of the middle part of the rotating body and the rotation axis.

[0011] Optionally, the outer circumference of the rotating body gradually increases from the middle to the end.

[0012] Optionally, the outer circumference of the rotating body first increases gradually toward the end and then decreases gradually.

[0013] Optionally, the rotating body has two ends distributed along the rotation axis, and the outer circumference of the rotating body gradually increases from one end to the other end.

[0014] Optionally, the rotating body has a longitudinal section along the rotation axis, and the outer periphery of the longitudinal section is wavy.

[0015] Optionally, a mounting channel extending along the rotation axis is formed in the rotating body, and a water-spinning channel is provided on the peripheral side of the rotating body;

[0016] The air purification module also includes a water tank and a water spray pipe installed on the shell, one end of the water spray pipe is connected to the water tank, the other end of the water spray pipe extends into the installation channel, and the water spray pipe is provided with a water spray hole connected to the water throwing channel.

[0017] Optionally, when the air purification module is working, the linear speed of the outer edge of the rotating body is 10m / s to 45m / s.

[0018] Optionally, when the air purification module is working, the linear speed of the outer edge of the rotating body is 20m / s to 30m / s.

[0019] The present invention also provides an air conditioner indoor unit, comprising:

[0020] A casing, wherein the casing is provided with a heat exchange air inlet, a heat exchange air outlet, a purification air inlet and a purification air outlet, and the heat exchange air inlet is connected to the heat exchange air outlet; and

[0021] An air purification module is located in the housing, and a purification air duct of the air purification module is connected to the purification air inlet and the purification air outlet respectively.

[0022] The present invention also provides an air conditioner, comprising:

[0023] Air conditioner outdoor unit; and

[0024] An air-conditioning indoor unit is connected to the air-conditioning outdoor unit via a refrigerant pipe.

[0025] In the present invention, due to the shape feature of the rotating body, there are at least multiple positions on its outer circumference with different distances to the axis of rotation, that is, the rotation radius of each position or part of the rotating body is different, and different rotation radii have different supergravity accelerations. The centrifugal forces on the water particles at different rotation radii are also different. Therefore, the motion state of the water particles finally ejected from different positions of the rotating body is different, which makes the diameters of the water particles different. In addition, the water particles are ejected at high speed along the tangent direction of the rotating body due to the action of centrifugal force, and the tangent directions at multiple positions of the rotating body are different from the orderly arrangement of the tangents of the cylindrical rotating body. The tangent arrangement of various parts of the rotating body is relatively messy and disordered, so the arrangement of the water particles ejected from different positions is disordered. In this way, the disordered water particles and water particles of different sizes are fully in contact with the air, which can capture pollutants of different particle sizes, and the purification range is wider, which improves the purification effect. And the water washing method can reduce the cost increase while effectively purifying the air. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] 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

[0047] 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.

[0048] 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, a floor-standing 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.

[0049] Please refer to Figures 8 to 10 as well as Fig.15 Specifically, the air purification module 100 in the present invention includes a housing 110, a rotating body 120 and a driving device. Among them, the housing 110 is provided with an air inlet, an air outlet and a purification air duct 113 connecting the air inlet and the air outlet. The indoor air or fresh air enters the housing 110 from the air inlet, and is cleaned by the water sprayed by the rotating body 120 arranged in the housing 110, and then blown out from the air outlet. In order to distinguish from the air inlet and air outlet of the air conditioner, and facilitate the subsequent better description, the air inlet of the housing 110 is defined as the air inlet 111, and the air outlet of the housing 110 is defined as the air outlet 112 for explanation. The housing 110 is generally cylindrical and extends in the up and down direction. For example, the housing 110 can be square or circular, etc. In addition, the housing 110 can also be a structure with two ends sealed. In one embodiment, the air inlet 111 is arranged at the bottom of the housing 110, and the air outlet 112 is arranged at the top of the housing 110 to achieve lower air intake and upper air outlet. It should be noted that the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), and 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 indication will also change accordingly.

[0050] The rotating body 120 is rotatably arranged in the housing 110, that is, rotatably arranged in the purification air duct 113. When water is sprayed on the rotating body 120, the rotating body 120 throws the water outward by rotating. Specifically, the rotating body 120 has a rotation axis, and a mounting channel 123 extending along the rotation axis is formed in the rotating body 120, and a water-throwing channel 124 is provided on the circumference of the rotating body 120. The rotating body 120 is used to throw the water sprayed on the rotating body 120 out from the water-throwing channel 124, and the thrown water is sprayed around the housing 110. In one embodiment, the water source is connected to the mounting channel 123, that is, the water is directly provided to the mounting channel 123, and then thrown out from the water-throwing channel 124. In one embodiment, a water spray pipe 141 is provided in the mounting channel 123, and a water spray hole is provided on the water spray pipe 141. The water source is connected to the water spray pipe 141, and the water is thrown out from the water spray hole through the water-throwing channel 124122.

[0051] Optionally, the air inlet 111 is located below the rotating body 120, and the air outlet 112 is located above the rotating body 120, so that the air moves from bottom to top, and the water sprayed from the rotating body 120 flows from top to bottom under the influence of gravity, and the air collides with the water to be purified.

[0052] In the present invention, when the rotating body 120 rotates at high speed, a huge centrifugal force is generated. The water in the installation channel 123 (or the water sprayed from the water spray pipe 141) has supergravity acceleration under the action of the rotating body 120 and moves at high speed. When passing through the water-spinning channel 124, dispersed droplets are generated and thrown outward. The small droplets moving at high speed collide with the particles in the air. The water particles moving at high speed can clean the tiny dust in the air, and organic matter such as formaldehyde is dissolved in water, thereby playing a role in purifying the air. Since the water-spinning channel 124 is set on the rotating body 120, it can disperse the water flow into water particles and spray them out. Therefore, the water particles sprayed from multiple water-spinning channels 124 have a larger coverage range and a better contact effect with the air, so the purification effect can be greatly improved.

[0053] The driving device is installed on the housing 110, and the driving device is connected to the rotating body 120 to drive the rotating body 120 to rotate along the rotation axis. In order to facilitate the subsequent distinction of other driving devices, the driving device that drives the rotating body 120 to rotate is taken as the first driving device 131 (please refer to the figure) as an example for explanation in the specification. The first driving device 131 is specifically a motor or other driving member that can drive the rotating body 120 to rotate. In the embodiment of the present invention, the first driving device 131 drives the rotating body 120 to rotate along the rotation axis of the rotating body 120, and the rotating body 120 generates a huge centrifugal force. When the water in the installation channel 123 flows to the water-throwing channel 124, it is ejected through the water-throwing channel 124. When the air enters the purification air duct 113, it contacts with the water particles, and the air is purified and humidified. The way of throwing water by the rotating body 120 can break up the water flow to form finer water particles, so that the contact area between the air and the water particles is larger, and the contact between the two is more sufficient, so the purification effect is better.

[0054] The air purification module 100 in the present invention also includes a water supply device 140 installed on the shell 110, and the water supply device 140 is used to supply water to the rotating body 120. Specifically, the water supply device 140 is connected to the water-throwing channel 124 to supply water to the water-throwing channel 124. It should be noted that the water supply device 140 referred to in the embodiment of the present invention is connected to the water-throwing channel 124 to supply water to the water-throwing channel 124, including but not limited to the following situations: In one embodiment, the water supply device 140 extends into the installation channel 123 to spray water directly. Specifically, in this embodiment, the water supply device 140 includes a water spray pipe 141, which extends into the installation channel 123, and a water spray hole is provided on the water spray pipe 141 to spray water toward the installation channel 123, and the water is then sprayed from the installation channel 123 to the water-throwing channel 124. In one embodiment, the water supply device 140 includes a water spray pipe 141, which extends into the installation channel 123. The water spray pipe 141 is provided with a water spray hole to spray water directly toward the water-spinning channel 124, and the water sprayed from the water spray hole is directly sprayed from the water-spinning channel 124 without passing through the installation channel 123. In one embodiment, the water supply device 140 is located outside the installation channel 123 and is disposed near one end of the installation channel 123, and sprays water from the outside into the installation channel 123. For example, the water spray pipe 141 is located outside the installation channel 123 and does not extend into the installation channel 123.

[0055] Specifically, a plurality of water spray holes are provided on the peripheral side of the water spray pipe 141 so as to spray water in all directions. Alternatively, a water spray hole is provided at the end of the water spray pipe 141 for spraying water. In addition, a plurality of spray arms may be provided on the water spray pipe 141 for spraying water. Optionally, the aperture of the water spray hole is less than or equal to 5 mm, which can ensure that the sprayed water droplets are small and achieve a better atomization effect.

[0056] In one embodiment, the water supply device 140 further includes a water tank 142, which is mounted on the housing 110. Specifically, the water tank 142 is mounted on the outer bottom of the housing 110. In addition, the water tank 142 can also be mounted inside the housing 110. The housing 110 is generally cylindrical with upper and lower ends connected, and its lower end is covered on the upward opening of the water tank 142. One end of the water spray pipe 141 is connected to the water tank 142, and the other end of the water spray pipe 141 is connected to the installation channel 123. In addition, the water supply device 140 further includes a water pump, which is located on the connecting pipeline between the water tank 142 and the water spray pipe 141, and is used to transport the water in the water tank 142 to the water spray pipe 141. In one embodiment, the water tank 142 is located inside the housing 110 and directly below the rotating body 120, so that the water sprayed by the rotating body 120 can flow back to the water tank 142, realizing the recycling of water.

[0057] Specifically, the rotating body 120 includes a plurality of rotating rings 121 and a connecting member 122. The plurality of rotating rings 121 are sequentially arranged at intervals along the rotation axis, i.e., stacked, and the connecting member 122 connects the plurality of rotating rings 121 into one. The central areas of the plurality of rotating rings 121 are hollow to form an installation channel 123 extending along the rotation axis of the rotating body 120, and the gap between two adjacent rotating rings 121 forms a water-spinning channel 124 that is connected to the installation channel 123.

[0058] In the embodiment of the present invention, a large rotating body 120 is divided into a plurality of rotating rings 121. Since the plurality of rotating rings 121 are stacked and arranged at intervals, it is equivalent to a single rotating ring 121 rotating, so the shaking can be reduced. In addition, the gap between two adjacent rotating rings 121 can buffer the shaking, avoid or reduce the shaking from being transmitted to other rotating rings 121, and thus greatly improve the rotation stability of the entire rotating body 120. In addition, since the rotating body 120 is thrown out of water through the gap between two adjacent rotating rings 121, there is a gap in the entire circumferential direction, and the water throwing efficiency is high, that is, it is covered by water particles in the entire circumferential direction, so the contact range with the air is larger and the purification effect is better. At the same time, the water thrown out through the gap can form finer water particles under the action of centrifugal force, and can contact with the air more fully, so it can effectively ensure that the air purification module 100 has a high processing capacity for air purification.

[0059] In one embodiment, the connecting member 122 is in the shape of an elongated strip and extends along the rotation axis. In one embodiment, the connecting member 122 includes a connecting rod and a plurality of strip-shaped bodies arranged on the connecting rod, the connecting rod extends along the rotation axis, the plurality of strip-shaped bodies are arranged at intervals along the length direction of the connecting rod, and each strip-shaped body is connected to the rotating ring 121 adjacent to it. The connecting rod can be arranged on the periphery of the rotating body 120, and the strip-shaped bodies are also located outside the rotating body 120. In one embodiment, the connecting rod is arranged on the inner periphery of the rotating body 120, that is, in the installation channel 123, and a plurality of strip-shaped bodies are connected to the same rotating ring 121, and the plurality of strip-shaped bodies connected to the same rotating ring 121 are arranged radially with the connecting rod as the center, so that the installation stability of the rotating body 120 can be improved, and the problem of the overall structure being too large caused by setting the connecting member 122 outside the rotating body 120 can be avoided.

[0060] In other embodiments, the rotating body 120 may be an integral structure, and the water-shedding channel 124 is a water-shedding hole opened on the circumference of the rotating body 120 . The water-shedding hole may be a circular hole, a bar hole, a triangular hole, etc.

[0061] In one embodiment, the rotating body 120 is non-cylindrical or the rotating body 120 is non-columnar. Specifically, the rotating body 120 has a first point and a second point located on its outer circumference, and the distance from the first point to the rotation axis is different from the distance from the second point to the rotation axis.

[0062] In the embodiment of the present invention, due to the shape feature of the rotating body 120, there are at least multiple positions on its outer circumference with different distances to the rotation axis, that is, the rotation radius of each position or part of the rotating body 120 is different, and different rotation radii have different supergravity accelerations. The centrifugal forces on the water particles at different rotation radii are also different. Therefore, the motion states of the water particles finally ejected from different positions of the rotating body 120 are different, which makes the diameters of the water particles different. In addition, due to the action of centrifugal force, the water particles are ejected at high speed along the tangent direction of the rotating body 120, and the tangent directions at multiple positions of the rotating body 120 are different from the orderly arrangement of the tangents of the cylindrical rotating body 120. The tangent arrangement at various positions of the rotating body 120 is relatively disordered, so the arrangement of the water particles ejected from different positions is disordered. In this way, the disordered water particles and water particles of different sizes are fully in contact with the air, which can capture pollutants of different particle sizes, and the purification range is wider, which improves the purification effect.

[0063] The specific structure of the rotating body 120 is described below by taking multiple embodiments as examples, but is not limited thereto, as long as the rotating body 120 can be ensured to be non-cylindrical or non-columnar:

[0064] Please refer to Figures 3 to 7 In one embodiment, the rotating body 120 is in a shape with small ends and large middle. Specifically, the rotating body 120 has two ends distributed along the rotation axis, and the distance from the outer circumference of the ends of the rotating body 120 to the rotation axis is smaller than the distance from the outer circumference of the middle of the rotating body 120 to the rotation axis. In this embodiment, the outer circumference of the rotating body 120 gradually decreases from the middle to the ends. For example, the rotating body 120 is spherical (such as Figure 3 As shown), ellipsoidal (as Figure 6 When the rotating body 120 is spherical, the rotation axis passes through the center of the rotating body 120. When the rotating body 120 is ellipsoidal, the rotation axis coincides with the long axis of the rotating body 120. Alternatively, in other embodiments, as Figure 7 As shown, the rotating body 120 includes a plurality of rotating parts 125 distributed along the rotation axis and connected in sequence, and among two adjacent rotating parts 125, the outer circumferential size of the rotating part 125 close to the end of the rotating body 120 is smaller than the outer circumferential size of the other rotating part 125. The structure of each rotating part 125 is generally the same, and only the outer circumferential size varies. For example, the rotating part 125 can be in the shape of a cube or a truncated cone.

[0065] In this embodiment, since the rotating body 120 is a structure with small ends and large middle, the water droplets at the ends of the rotating body 120 are subjected to large centrifugal force and move faster, and the space formed between the ends of the rotating body 120 and the shell 110 is larger, so it can be ensured that the water droplets at the ends can fully interact with the air to remove particulate matter in the air. The water droplets in the middle of the rotating body 120 are subjected to small centrifugal force and move slower, and the space formed between the middle of the rotating body 120 and the shell 110 is relatively smaller, so even if the water droplets in the middle move at a low speed, the water droplets can still fully interact with the air because the amount of air is relatively smaller.

[0066] Please refer to Figures 8 to 14 In one embodiment, the rotating body 120 is in a shape that is large at both ends and small in the middle. Specifically, the rotating body 120 has two ends distributed along the rotation axis, and the distance between the outer circumference of the ends of the rotating body 120 and the rotation axis is greater than the distance between the outer circumference of the middle portion of the rotating body 120 and the rotation axis. In this embodiment, the outer circumference of the rotating body 120 gradually increases from the middle portion toward the ends, for example, the rotating body 120 is in the shape of a waist drum. In other embodiments, the outer circumference of the rotating body 120 first gradually increases and then gradually decreases from the middle portion toward the ends. For example, the rotating body 120 is in the shape of a gourd, etc.

[0067] Please refer to Fig.15 and Fig.16 In one embodiment, the rotating body 120 is in a shape with one end larger than the other end. Specifically, the rotating body 120 has two ends distributed along the rotation axis, and the outer circumference of the rotating body 120 gradually increases from one end to the other end. In this embodiment, the rotating body 120 is in a cone, a truncated cone, a quadrangular pyramid, etc.

[0068] Please refer to Fig.17 In one embodiment, the rotating body 120 has a longitudinal section along the rotation axis, and the outer periphery of the longitudinal section is wavy, that is, the rotating body 120 is a structure formed by stacking multiple gourd structures in sequence along the rotation axis.

[0069] In addition, at least one filter cartridge is sleeved on the outer periphery of the rotating body 120. The pores of the filter cartridge are small, which can further disperse the water. A filter screen can also be set at the end of the rotating body 120 to achieve a better atomization effect on the water.

[0070] Please refer to it again Fig.15In one embodiment, a purification fan 150 is further provided in the housing 110, and the purification fan 150 can be located above the rotating body 120. Of course, the purification fan 150 can be set at any position of the purification air duct 113. Under the action of the purification fan 150, air flows from the air inlet 111 to the air outlet 112. Optionally, the purification fan 150 is a centrifugal fan. Further, the air purification module 100 also includes a second drive device 132, which is connected to the purification fan 150 and drives the purification fan 150 to rotate.

[0071] In one embodiment, when the air purification module 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.

[0072] Furthermore, in this embodiment, when the air purification module 100 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.

[0073] Please refer to Figure 1 , Figure 2 and Fig.15 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 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 housing 200 extends in the up and down directions. The housing 200 is provided with a heat exchange air inlet 210, a heat exchange air outlet, and a heat exchange air duct (not shown) connecting the heat exchange air inlet 210 and the heat exchange air outlet. 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 210, and after heat exchange through the heat exchanger, it is blown out from the heat exchange air outlet.

[0074] 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.

[0075] 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 air inlet 111, and the purification air outlet 230 is connected to the air outlet 112. Since the rotating body 120 is wrapped by the shell 110 and then installed in the housing 200, the shell 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 air inlets 111 are provided on the peripheral side of the shell 110 to allow air to enter from a plurality of circumferential positions, thereby better increasing the contact area with water.

[0076] 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 150, and flows into the purification air duct 113 from the air inlet 111. The water pump 143 transports the water in the water tank 142 to the water spray pipe 141, and the water spray pipe 141 sprays the water from the water spray hole to the surrounding areas to produce atomization; the rotating body 120 rotates under the drive of the first driving device 131, and the centrifugal force generated by the high-speed rotating body 120 produces super gravity, and then atomizes the water again to form finer water droplets, and throws the water droplets to the purification air duct 113 around, and forms fine water particles in the purification air duct 113. The air is fully in contact with the water particles in the purification air duct 113, and the particulate matter in the air (such as large dust particles, PM2.5, formaldehyde, sulfur dioxide, bacteria or viruses, etc.) is captured by the water particles and falls, and flows back to the water tank 142. The purified air flows upward and flows into the air duct of the purification fan 150 through the air outlet 112 , and is finally blown out from the purification air outlet 230 on the housing 200 .

[0077] 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.

[0078] 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.
