And can be adjusted as needed by those skilled in the art to suit particular applications. For example, although the air purifying apparatus according to the embodiment of the present invention is described in connection with an air conditioner, the air purifying apparatus is not limited to be applied to the air conditioner, and other devices having air purifying requirements may be configured with the air purifying apparatus according to the embodiment of the present invention.
Next, it should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "inside", "outside", and the like are based on the direction or positional relationship shown in the drawings, which are only for convenience of description, and do not indicate or imply that the device or member must have a specific orientation, be constructed in a specific orientation, and operate, and thus, should not be construed as limiting the present invention.
Furthermore, it should be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "connected" and "connected" should be interpreted broadly, e.g., as being fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the two components can be directly connected or indirectly connected through an intermediate medium, and the two components can be communicated with each other. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The terms "upper", "lower", "top", "bottom" and the like as used herein refer to the orientation of the air purification apparatus in the normal operation state. The foregoing directional terms are used for convenience of description only and do not constitute any limitation on the structure.
In a correlation technique, air purification device's water knockout subassembly includes water knockout sleeve and transmission shaft, and wherein, water knockout sleeve includes upper cover, upper sleeve structure and lower sleeve structure triplex, is provided with the water hole of getting rid of at upper sleeve structure. In the using process, the transmission shaft is utilized to drive the water throwing sleeve to rotate at a high speed so as to generate negative pressure, so that water in the water tank is pumped into the water throwing sleeve and is thrown out of the water throwing holes to form a water curtain. The structure of the water throwing sleeve is complex, and the number of parts is large, so that the assembly efficiency of the air purifying device is influenced, and the production cost is improved. To provide sufficient suction to the water in the water tank, the hydro-extracting sleeve needs to rotate at a high speed, and the complex structure easily causes the rotation clamping stagnation of the hydro-extracting sleeve and abnormal sound in the rotation process. In addition, because the water throwing hole sets up on last sleeve structure, quantity is limited, and is lower to the humidification and the purification efficiency of air.
In view of the above problems, an embodiment of the present invention provides an air purification apparatus, in which a material of a water-throwing blade is a hydrophilic and/or water-absorbing material, water in a water tank is lifted by rotation of the water-throwing blade, the water-throwing blade absorbs water in the water tank and wets the whole water-throwing blade by virtue of the hydrophilic/water-absorbing characteristics of the material, the water absorbed by the water-throwing blade can be thrown out through a water-throwing hole during rotation, and the two materials are combined to humidify and purify air entering the water tank.
An air cleaning device according to an embodiment of the present invention is described below with reference to the drawings.
Referring to fig. 1, fig. 1 is a cross-sectional view of an air cleaning apparatus according to an embodiment of the present invention. As shown in fig. 1, an air purification apparatus according to an embodiment of the present invention includes a water tank 10, a blower (not shown), a motor 20, and a water throwing structure 30. The water tank 10 is provided with an air inlet and an air outlet, and the fan is used for driving air to flow into the air inlet and be discharged from the air outlet, so that an air flow path in the water tank is formed between the air inlet and the air outlet. The motor 20 is used for driving the water throwing structure 30 in the water tank 10 to rotate, so that water in the water tank 10 is raised to form a water curtain, air entering the water tank 10 is filtered and humidified by the water curtain, dust, bacteria, viruses and the like in the air are dissolved in the water or water molecules and negative ions formed by the water throwing structure 30 are removed, and the air is washed and purified.
The water throwing structure 30 includes a middle shaft 31 and water throwing blades 32 connected to the outer side surface of the middle shaft 31, wherein the middle shaft 31 is connected to the motor shaft 21 of the motor 20, so that the middle shaft 31 and the water throwing blades 32 are driven to rotate by the motor 20. The water throwing blades 32 are provided with a plurality of water throwing holes, the material of the water throwing blades 32 comprises a hydrophilic material and/or a water absorbing material, namely, the material of the water throwing blades 32 can be the hydrophilic material, can also be the water absorbing material, and can also have both the hydrophilic material and the water absorbing material. In this way, the hydrophilic/absorptive properties of the hydro-extracting blades 32 are utilized to absorb water in the water tank 10 so that the entire hydro-extracting blades 32 are wetted. It is understood that "hydrophilic" as used herein refers to molecules having polar groups, which have a greater affinity for water and attract water molecules, and hydrophilic materials such as ABS plastic, PPO (polyphenylene oxide), PS (polystyrene), etc. The term "water-absorbing" as used herein refers to a property of absorbing water in water, and examples of the water-absorbing material include pet (polyethylene terephthalate), nylon, and the like.
Among the above-mentioned air purification device, the blade 32 that gets rid of among the structure 30 of getting rid of water sets up to hydrophilic and/or the material that absorbs water, when motor 20 drive gets rid of the structure 30 of getting rid of water and rotates, on the one hand, the rotation of getting rid of the blade 32 of getting rid of can be with the water in the water tank 10 being raised, on the other hand, get rid of the blade 32 of getting rid of water and throw away its absorptive water by getting rid of the water hole through rotating in the water tank 10, both combine to realize humidification and purification to the air that gets into in the water tank 10, moreover, the steam generator is simple in structure, can effectively improve assembly efficiency, and the production cost is reduced. Because the hydro-extracting blades 32 have hydrophilic/hydrophilic properties, the water level in the water tank 10 can be set to be low, and the whole hydro-extracting blades 32 can be wetted by the hydrophilic/hydrophilic properties of the hydro-extracting blades 32, so that waste of water resources is avoided. In addition, due to the fact that the number of parts is reduced, abnormal sound is not prone to being generated when the water throwing structure 30 rotates, and the problem of blocking cannot occur.
The air inlet and the air outlet of the water tank 10 can be arranged at any positions of the water tank 10, so that an air flow path formed between the air inlet and the air outlet by the fan can flow through the water curtain thrown out by the water throwing structure 30. In a specific embodiment, the air inlet is disposed at a side portion of the water tank 10, and the air outlet is disposed at a top portion of the water tank 10, fig. 2 is an air path diagram of the air purification apparatus, and as shown in fig. 2, the air inlet and the air outlet are disposed at positions to form an airflow path for side air inlet and top air outlet. Suitably, the axis of the middle shaft part 31 of the water slinging structure 30 extends vertically, i.e. in an up-and-down direction. Thus, in the lower portion of the tank 10, the flow path of the airflow is substantially horizontal or at a small angle to the horizontal, while in the upper portion of the tank 10, the flow path of the airflow is substantially vertical or at a small angle to the vertical.
The size of the water throwing holes on the water throwing blades 32 can be the same or different. In the embodiment of the water tank 10 having the air inlet at the side and the air outlet at the top, as shown in fig. 2, since the air flow impacting the lower portion of the water throwing blade 32 is substantially horizontal, and the air flow impacting the upper portion of the water throwing blade 32 is substantially vertical, preferably, the aperture of the water throwing hole at the lower portion of the water throwing blade 32 is larger than the aperture of the water throwing hole at the upper portion of the water throwing blade 32, so that the air flow impacting the lower portion of the water throwing blade 32 passes through the water throwing hole as much as possible to drive the water thrown out from the water throwing hole, and the water throwing hole with the smaller aperture at the upper portion of the water throwing blade 32 throws more water out to form a finer water curtain, so as to utilize the finer water curtain to better humidify and purify the air flow moving vertically.
The aperture of the water throwing hole can be gradually increased from bottom to top, or the water throwing blade 32 can be divided into an upper part and a lower part, the aperture of the water throwing hole in the upper half part is the same, the aperture of the water throwing hole in the lower half part is also the same, and the aperture of the water throwing hole in the upper half part is only set to be smaller than that of the water throwing hole in the lower half part.
The number of the water throwing blades 32 is not limited, and may be one or more, and in order to improve the efficiency of humidifying and purifying air, a plurality of water throwing blades 32 are preferably provided, and the plurality of water throwing blades 32 are uniformly arranged along the circumferential direction of the middle shaft portion 31. For example, fig. 3 is a schematic view of a water slinging structure of an air purification apparatus provided in an embodiment of the present invention, and in the embodiment shown in fig. 3, three water slinging blades 32 are provided. Of course, it is understood that the number of the water slinger blades 32 may also be two, four or more.
Since the hydrophilic/water-absorbing property of the water throwing blade 32 itself is utilized to absorb water in the water tank 10 in the embodiment of the present application, the arrangement position of the water throwing hole is not limited, and the water throwing hole can be arranged at any position of the water throwing blade 32. Namely, the arrangement position, the arrangement mode and the quantity of the water throwing holes are not limited. In order to improve the efficiency of humidification and purification of air, it is preferable that the water slinging holes are distributed over the entire water slinging blade 32. In a specific embodiment, as shown in fig. 1 and 3, the hydro-extracting blade 32 includes a blade main body 321, the blade main body 321 is connected to the middle shaft 31, the hydro-extracting holes include a plurality of first hydro-extracting holes 3211 disposed on the blade main body 321, and the plurality of first hydro-extracting holes 3211 are arranged in an array on the blade main body 321, that is, the blade main body 321 is provided with a plurality of rows and a plurality of columns of first hydro-extracting holes 3211 distributed in an array.
The blade main body portion 321 may be provided in any shape, for example, in a rectangular plate-like structure, a triangular plate-like structure, or the like. In order to improve the water pumping effect of the blade main body 321 during the rotation process, as shown in fig. 3, the cross section of the blade main body 321 is preferably curved, and the curved direction of the blade main body 321 of each water slinging blade 32 is the same, so that the water in the water tank 10 can be pumped up better when each water slinging blade 32 rotates synchronously, and the air humidifying and filtering effect is further improved. The cross section described herein refers to a plane where a horizontal plane is taken on the blade main body portion 321. The curved shape may be an arc shape, may be formed by smoothly connecting a plurality of arc shapes having different radii of curvature, or may be a shape in which the radius of curvature is constantly changed. In order to increase the rotational resistance of the floor hydro-extracting blades 32, it is preferable that the curvature radius of the curved shape formed in the cross section of the blade body 321 gradually increases from the radially inner side of the middle shaft portion 31 toward the radially outer side.
For convenience of processing, the blade main body portion 321 may be configured to have a uniform vertical dimension. Since the hydro-extracting blade 32 mainly absorbs water through the lower structure, in order to provide a larger lift force for the rising of the moisture, it is preferable that the blade main body 321 is configured to have a lower size larger than an upper size, so that the blade main body 321 can have more structures to directly contact with the water in the tank 10, thereby enabling the water in the tank 10 to be more rapidly transported to each position of the blade main body 321.
In order to obtain a larger water slinging range, it is further preferable that the axes of the first water slinging holes 3211 located at the same height have an included angle, that is, in the blade main body 321 of one water slinging blade 32, the axes of the first water slinging holes 3211 located in the same row are not parallel. In this way, in the same height, the orientations of the first water throwing holes 3211 are different, so that the water throwing directions of the first water throwing holes 3211 are different from each other, and thus, the water throwing coverage area at the height position can be increased. The first water slinging holes 3211 at each height are all set to have included angles between axes, so that the overall water slinging range of the blade main body 321 is improved, and the water slinging uniformity of the blade main body 321 is ensured.
In the embodiment shown in fig. 3, the hydro-slinger blades 32 comprise only blade body portions 321. It will be appreciated that the hydro-slinger blades 32 may also include other parts. For example, in the embodiment that the air inlet is disposed at the side part of the water tank 10 and the air outlet is disposed at the top part, since the flow direction of the air flow reaching the upper part of the water slinging blade is substantially vertical, in order to further improve the purifying and humidifying effect of the air flow reaching the area, preferably, fig. 4 is a top view of the water slinging structure in the air purifying device according to another embodiment of the present invention, as shown in fig. 4, the water slinging blade 32 further includes a first extending plate part 322 extending from the top part of the blade main body part 321 along the circumferential direction, and the plurality of water slinging holes further include a second water slinging hole 3221 disposed on the first extending plate part 322. Since the air flow in the area of the first extension portion 322 is substantially vertical, the air flow can pass through the second water throwing holes 3221 on the first extension portion 322 more for purification and humidification, thereby further improving the air purification and humidification efficiency of the air purification device.
In order to avoid the air output of the air purification device being affected by the blocking of the airflow caused by the arrangement of the first extension plate portion 322, it is preferable that the first extension plate portion 322 is arranged in a spiral blade shape, so that when the water throwing blade 32 rotates, the first extension plate portion 322 can provide a lifting force for the flow of the airflow, thereby ensuring the air output of the air purification device. Further preferably, the fan includes an axial flow fan disposed at the top of the water tank 10, and a spiral direction of the first extension plate 322 is the same as a spiral direction of a blade of the axial flow fan, so that the first extension plate 322 and the blade of the axial flow fan form a relay on the air path, and an air output of the air purification apparatus is further ensured.
Because structures such as a sterilization bottle and the like are required to be arranged in the water tank 10, the projection area of the rotation range of the water throwing blade 32 in the horizontal plane is smaller than the area of the air outlet, and part of air is discharged through the space between the side wall of the water tank 10 and the water throwing blade 32 without being purified and humidified. To solve this problem, in a preferred embodiment, fig. 5 is a front view of a water-throwing structure in an air purification apparatus according to still another embodiment of the present invention, and as shown in fig. 5, the water-throwing blade 32 further includes a second extending plate portion 323 extending radially outward from an upper portion of the blade body portion 321, the plurality of water-throwing holes further include third water-throwing holes 3231 provided in the second extending plate portion 323, and an upper space region of the water tank 10 is compensated by the second extending plate portion 323, thereby further improving air purification and humidification efficiency of the air purification apparatus.
It is understood that the first extension plate portion 322 and the second extension plate portion 323 can be disposed according to specific requirements, that is, the hydro slinger blade 32 can be disposed with the first extension plate portion 322 only on the blade main body portion 321, with the second extension plate portion 323 only on the blade main body portion 321, or with both the first extension plate portion 322 and the second extension plate portion 323 on the blade main body portion 321.
In order to guide the air from the air inlet to the lower region of the water slinging blade 32 more downward, it is further preferable that, as shown in fig. 1, the water tank 10 includes a water tank body 11 and a partition sleeve 12 disposed in the water tank body 11, the air inlet is disposed on the side wall of the water tank body 11, the air outlet is disposed at the top of the water tank body 11, and the partition sleeve 12 extends from the top of the water tank body 11 to below the air inlet. As shown in fig. 2, by providing the partition sleeve 12, the air flow entering from the air inlet does not directly flow to the region of the water throwing blade 32 with the same height as the air inlet, but bypasses the bottom end of the partition sleeve 12 under the drainage action of the partition sleeve 12, and at the same time, flattens the flow direction of the air under the action of the axial flow fan, and further flows upwards. Therefore, the flow path of the air flow can be prolonged, and the air flow can be guided to the lower area of the water throwing blades 32 with more moisture, so that the water washing effect and the water washing efficiency of the air purification device on the air are further improved.
Further preferably, the bottom end of the partition sleeve 12 is extended radially inward to form a partition ring plate, which is provided to prevent the gas flow from being directly discharged from the space between the partition sleeve 12 and the water slinger blade 32, similarly to the second extension plate portion 323.
In another embodiment, fig. 6 is a schematic cross-sectional view of a water slinger blade in an air purification apparatus according to still another embodiment of the present invention, as shown in fig. 6, the water slinger blade 32 may be further configured in a wave shape, specifically, the water slinger blade 32 includes at least one wave plate layer 324, the wave plate layer 324 includes a plurality of first bending portions 3241 and a plurality of second bending portions 3242, the first bending portions 3241 and the second bending portions 3242 extend in an axial direction of the middle shaft portion 31, the cross-sections of the first bending portions 3241 and the second bending portions 3242 are curved and have opposite bending directions, and in the one wave plate layer 324, the plurality of first bending portions 3241 and the plurality of second bending portions 3242 are alternately connected in a radial direction of the middle shaft portion 31, so as to form a wave-shaped structure. Each first bending portion 3241 is provided with a plurality of water throwing holes arranged at intervals along the extending direction of the first bending portion, and each second bending portion 3242 is provided with a plurality of water throwing holes arranged at intervals along the extending direction of the second bending portion.
