The water in the water storage structure 10 may be condensed water inside the air treatment device 1000 such as a window unit, an outdoor unit of an air conditioner, or a mobile air conditioner, or may be tap water, rainwater, or other water bodies.

The water fetching structure 20 may be a water fetching ring, the central axis of the water fetching ring is horizontally disposed, the bottom of the water fetching ring is located in the water storage space of the water storage structure 10, and the top of the water fetching ring is located above the water storage space of the water storage structure 10. Further, the water-beating ring can rotate around its axis, so that its bottom can beat up the water in the water storage structure 10. Of course, in order to enable the water-fetching ring to rotate around its axis, the water distribution device 100 further comprises a driving assembly for driving the water-fetching ring to rotate around its central axis. In this embodiment, the driving component is an axial flow fan 50, the axial flow fan 50 includes a motor 51 and an axial flow wind wheel 53, and the water-beating ring is disposed around the outer edge of the axial flow wind wheel 53. When the axial flow fan 50 operates, the motor 51 drives the axial flow wind wheel 53 to rotate, and the axial flow wind wheel 53 drives the water beating ring to rotate, so that the bottom of the water beating ring can beat up water in the water storage structure 10.

Of course, those skilled in the art can implement other reasonable and effective embodiments according to the concept of the present invention, and the detailed description is omitted here.

In addition, the water fetching structure 20 may also be a water fetching plate, a water fetching wheel, or other reasonable and effective water fetching structures 20.

Of course, the driving components corresponding to the other water fetching structures 20 can also be reasonably and effectively arranged, and are not described in detail herein.

Part of the water collecting and distributing structure 30 is located above the water fetching structure 20 and is used for collecting water in the water storage structure 10 fetched by the water fetching structure 20; meanwhile, a part of the water collecting and distributing structure 30 is located above the heat exchanger 200, and is used for guiding the collected water in the water storage structure 10 to the heat exchanger 200. It should be noted that the water may be guided to the heat exchanger 200 vertically from directly above the heat exchanger 200, or may be guided to the heat exchanger 200 obliquely from obliquely above the heat exchanger 200. Specifically, the water collecting and distributing structure 30 may be a plate-shaped structure, which is obliquely disposed above the water fetching structure 20 and the heat exchanger 200 at a certain angle with the horizontal plane, and the height of the plate-shaped structure gradually decreases from the water fetching structure 20 to the heat exchanger 200. At this time, the lower surface of the plate structure can collect the water in the water storage structure 10 pumped up by the pumping structure 20, and the part of the collected water in the water storage structure 10 can flow to the upper side of the heat exchanger 200 along the lower surface of the plate structure, and finally drops on the upper side of the heat exchanger 200 to contact with the heat exchanger 200, thereby completing the humidification process of the heat exchanger 200. Of course, water baffles may be protruded toward the water storage structure 10 (downward) around the plate structure to obtain a cover structure integrating the water collecting function and the water distributing function, thereby realizing more efficient water collecting and distributing.

Therefore, it can be understood that, according to the technical solution of the present embodiment, by disposing at least part of the water pumping structure 20 in the water storage structure 10, the water in the water storage structure 10 can be pumped up by using the water pumping structure 20; then, by arranging at least part of the water collecting and distributing structure 30 above the water beating structure 20, the water which is beaten up can be collected by the water collecting and distributing structure 30; finally, by disposing at least a part of the water collecting and distributing structure 30 above the heat exchanger 200 of the air treatment device 1000, the collected water can be guided to the heat exchanger 200 by the water collecting and distributing structure 30, and the humidifying process for the heat exchanger 200 is completed. At this time, the heat exchanger 200 obtains an additional humidification process and additional cooling capacity in the air treatment device 1000, and the heat exchange efficiency is greatly improved, so that the energy efficiency of the air treatment device 1000 is improved.

As shown in fig. 1 to 5, in an embodiment of the air treatment device 1000 of the present invention, the water collecting and distributing structure 30 includes a water collecting structure 31 and a water distributing structure 33;

the water collecting structure 31 is arranged above the water fetching structure 20 and used for collecting water fetched by the water fetching structure 20 and guiding the collected water into the water distributing structure 33;

the water distribution structure 33 is disposed above the heat exchanger 200, and is configured to receive the water collected by the water collection structure 31 and guide the water to the heat exchanger 200.

Specifically, the water collecting structure 31 may be a plate-shaped structure to collect water using a lower surface thereof; the cover structure can also be used for collecting water by utilizing the inner surface of the cover structure; accordingly, the water distribution structure 33 may be a plate-shaped structure to receive the collected water by using the upper surface thereof, and then the water flows to the edge along the upper surface thereof to be dropped toward the heat exchanger 200; or a tray structure, a box structure, a trough structure or a box structure to receive the collected water by using the internal space thereof, and then drip the water to the heat exchanger 200 by using the opening or the hole. Moreover, the diversion between the water collecting structure 31 and the water distributing structure 33 can be realized by directly dropping up and down, and can also be realized by arranging diversion structures such as a diversion pipe and a diversion trench between the water collecting structure 31 and the water distributing structure 33.

So, catchment water distribution structure 30 is split into two relatively independent simple parts, can independently produce separately after making again together assemble, like this, has not only reduced the degree of difficulty of producing and making, has promoted the efficiency of producing and making, has realized still dismantling each other between the part moreover, has promoted the convenience of changing the maintenance, has promoted the practicality of product.

As shown in fig. 1 to 5, in an embodiment of the air processing apparatus 1000 of the present invention, a water storage tank 331 is concavely disposed on a surface of the water distribution structure 33 departing from the heat exchanger 200, and a water distribution hole 332 communicating with the water storage tank 331 is disposed on a surface of the water distribution structure 33 facing the heat exchanger 200.

Specifically, the water distribution holes 332 are disposed right above the heat exchanger 200, and at this time, water in the water storage tank 331 of the water distribution structure 33 may directly drop to the upper surface of the heat exchanger 200 through the water distribution holes 332, thereby completing the humidification process of the heat exchanger 200. At this time, the water collecting structure 31 is disposed adjacent to the water distributing structure 33 for collecting the water pumped by the water pumping structure 20 and guiding the collected water into the water storage tank 331 of the water distributing structure 33.

Therefore, the structure is simple, the production and the manufacture are convenient, and the reliability is high. And, the travel of the water drops before reaching the heat exchanger 200 is greatly shortened, the loss of the water drops is avoided, and the loss of the cooling capacity is avoided, so that the heat exchange efficiency of the heat exchanger 200 is effectively improved, and the energy efficiency of the air treatment device 1000 is improved.

Referring to fig. 6 and 7, in an embodiment of the air treatment device 1000 of the present invention, the bottom wall of the water storage tank 331 is provided with a first rib 334 around the water distribution hole 332, and the height of the first rib 334 is lower than the height of the side wall of the water storage tank 331. At this time, the water introduced into the water storage tank 331 from the water collection structure 31 cannot leak down from the water distribution holes 332 in the first time; it is necessary to accumulate in the water storage tank 331 so that the liquid level will leak down after rising to a height higher than the first rib 334, and impurities such as silt in the water body can be settled in the accumulation process of the water body. That is, utilize first flange 334 to be higher than aqua storage tank 331 diapire and the backstop effect that takes place, can make the water in the aqua storage tank 331 carry out the settlement process of impurity such as silt to the content of the top layer aquatic impurity in the greatly reduced aqua storage tank 331, and then reduce along with the water droplet leak down and with the quantity of impurity such as silt of heat exchanger 200 contact, reduce impurity such as silt to the erosion and the influence of heat exchanger 200, avoid heat exchange efficiency and the life of heat exchanger 200 to be influenced.

As shown in fig. 6 and 7, in an embodiment of the present invention of the air treatment device 1000, the height of the first rib 334 is defined as H, and the following condition is satisfied: h is more than or equal to 3mm and less than or equal to 6 mm. The height H of the first rib 334 should not be too high nor too low: if the height is too high, a large amount of water needs to be gathered in the water storage tank 331 to enable the water to leak down through the water distribution holes 332, and at the moment, a large amount of water cannot leak down, waste is generated, and a large amount of cold energy is lost; if it is too low, the settling effect of impurities such as silt will be obviously reduced, and at this moment, there will still exist some impurities such as silt and the like which invade the heat exchanger 200 along with the leakage of water drops, so as to erode and influence the heat exchanger 200, and the heat exchange efficiency and the service life of the heat exchanger 200 are influenced. Therefore, in the present embodiment, the height H of the first rib 334 is designed to be not less than 3mm and not more than 6 mm.

It is understood that in practical applications, the height H of the first rib 334 may be 3mm, 3.1mm, 3.2mm, 3.3mm, 3.5mm, 4mm, 4.5mm, 5mm or 6 mm.

As shown in fig. 6 and 7, in an embodiment of the air treatment device 1000 of the present invention, the aperture of the water distribution holes 332 is defined as D1, and the following condition is satisfied: d1 is more than or equal to 3mm and less than or equal to 6 mm. The aperture D1 of the water distribution holes 332 is not too large or too small: if the water volume is too large, the water in the water storage tank 331 leaks too fast, the water is not fully contacted with the heat exchanger 200 and flows and scatters, and the loss of cold energy is caused; if the water leakage rate is too small, the water leakage rate in the water storage tank 331 is too slow, and the humidification efficiency of the heat exchanger 200 is reduced, so that the improvement effect of the heat exchange efficiency of the heat exchanger 200 is weakened; in addition, the aperture D1 of the water distribution holes 332 is too small, so that the water distribution holes 332 are easily blocked by impurities such as silt, which causes poor water leakage, and the effect of improving the heat exchange efficiency of the heat exchanger 200 is weakened. Therefore, in this embodiment, the aperture D1 of the water distribution holes 332 is designed to be not less than 3mm and not more than 6 mm.

It is understood that in practical applications, the aperture D1 of the water distribution holes 332 may be 3mm, 3.1mm, 3.2mm, 3.3mm, 3.5mm, 4mm, 4.5mm, 5mm or 6 mm.

As shown in fig. 6 and 7, in an embodiment of the air treatment device 1000 of the present invention, an overflow hole 333 communicated with the water storage tank 331 is further opened on a surface of the water distribution structure 33 facing the heat exchanger 200, a second rib 335 is disposed around the overflow hole 333 on a bottom wall of the water storage tank 331, and the height of the second rib 335 is higher than the height of the first rib 334 and lower than the height of a side wall of the water storage tank 331. It can be understood that if the water distribution holes 332 are blocked, the liquid level in the water storage tank 331 will continuously rise; at this time, the arrangement of the overflow holes 333 and the second ribs 335 can make the water in the water storage tank 331 leak down from the overflow holes 333 and drip toward the heat exchanger 200 when the liquid level rises to a height higher than that of the second ribs 335, thereby realizing the humidification process of the heat exchanger 200, effectively avoiding the situation that the water overflows from the side wall of the water storage tank 331 when the water distribution holes 332 are blocked, causing a large amount of loss of cold energy, making the water distribution structure 33 still normally operate when the water distribution holes 332 are blocked, realizing the humidification of the heat exchanger 200, improving the heat exchange efficiency of the heat exchanger 200, improving the energy efficiency of the air treatment device 1000, and further improving the reliability of the water distribution device 100.

Specifically, the water distribution holes 332 are provided, and the water distribution holes 332 are arranged at intervals along the length direction of the water distribution structure 33. At this time, a plurality of overflow holes 333 are also provided, but the number is less than that of the water distribution holes 332, and each overflow hole 333 is arranged between two adjacent water distribution holes 332; the aperture of the overflow hole 333 is larger than that of the water distribution hole 332; thus, when the water distribution holes 332 are blocked, the overflow holes 333 can play an effective role in guiding water, ensure that the water body is guided to the heat exchanger 200, and ensure the normal operation of the water distribution structure 33.

As shown in fig. 6 and 7, in an embodiment of the air treatment device 1000 of the present invention, the difference between the height of the second rib 335 and the height of the first rib 334 is defined as L, so that the following condition is satisfied: l is more than or equal to 5mm and less than or equal to 8 mm. The difference L between the height of the second rib 335 and the height of the first rib 334 should not be too large or too small: if the water distribution hole 332 is too large, when the water distribution hole 332 is blocked, the liquid level in the water storage tank 331 needs to be higher than the second baffle 335 for a long time, so that the baffle is broken for a long time, the heat exchanger 200 is not humidified during the process, and the heat exchange efficiency is obviously reduced; moreover, the difference L between the height of the second rib 335 and the height of the first rib 334 is too large, so that a large amount of water is gathered in the water storage tank 331, on one hand, a large amount of water cannot leak down, which causes a loss of cooling capacity, and on the other hand, the stability of the water distribution structure 33 is affected by the too large weight of the large amount of water; if the water amount is too small, when the water collection efficiency of the water collection structure 31 is accelerated, the liquid level in the water storage tank 331 is easily higher than the second rib 335, and water leakage occurs at the same time from the water distribution hole 332 and the overflow hole 333, so that the water body leaks too much, and the water body is not fully contacted with the heat exchanger 200 and flows and scatters, resulting in loss of cooling capacity. Therefore, in the present embodiment, the difference L between the height of the second rib 335 and the height of the first rib 334 is designed to be within a range not lower than 5mm and not higher than 8 mm.

It is understood that in practical applications, the difference L between the height of the second rib 335 and the height of the first rib 334 may be 5mm, 5.1mm, 5.2mm, 5.3mm, 5.5mm, 6mm, 6.5mm, 7mm or 8 mm.

As shown in fig. 6 and 7, in an embodiment of the air treatment device 1000 of the present invention, if the aperture of the overflow hole 333 is defined as D2, the following condition is satisfied: d2 is more than or equal to 8mm and less than or equal to 15 mm. The diameter D2 of the overflow hole 333 should not be too large or too small: if the water distribution hole 332 is too large, when the water distribution hole 332 is blocked and the overflow hole 333 begins to guide the flow, the water body in the water storage tank 331 leaks too fast, the water body is not fully contacted with the heat exchanger 200 and flows and scatters, and the loss of cold energy is caused; if the water distribution hole 332 is too small, when the water distribution hole 332 is blocked and the overflow holes 333 start to guide the flow, the water in the water storage tank 331 leaks too slowly, and at the moment, because the number of the overflow holes 333 is small, not only the humidification efficiency of the heat exchanger 200 is reduced, but also the heat exchange efficiency of the heat exchanger 200 is reduced; and the liquid level in the water storage tank 331 may continue to rise and finally overflow from the side wall of the water storage tank 331, resulting in a great loss of cold. Therefore, in the present embodiment, the aperture D2 of the overflow hole 333 is designed to be not less than 8mm and not more than 15 mm.

It is understood that in practical applications, the aperture D2 of the overflow hole 333 may be 8mm, 8.1mm, 8.2mm, 8.3mm, 8.5mm, 9mm, 10mm, 12mm or 15 mm.
