The following description will be made taking a horizontal arrangement of the water distribution device 100 as an example.

Specifically, the chassis 300 is located at the bottom of the air conditioner outdoor unit 1000, and has a substantially disc structure, and is used for storing condensed water, tap water, rainwater or other water bodies generated in the air conditioner outdoor unit 1000. The casing 200 is covered on the upper surface of the chassis 300, and a first accommodating space 210 and a second accommodating space 220 are formed inside the casing 200, where the first accommodating space 210 and the second accommodating space 220 may be sequentially disposed along the length direction of the air conditioner outdoor unit 1000, or may be sequentially disposed along the width direction or the height direction of the air conditioner outdoor unit 1000. The heat exchanger 400 and the water distribution device 100 are located in the first accommodating space 210, and the compressor assembly 500 is located in the second accommodating space 220. The water-beating structure 10 of the water-distribution device 100 can be a water-beating ring, the central axis of the water-beating ring is horizontally arranged, the bottom of the water-beating ring is positioned in the water storage space of the chassis 300, and the top of the water-beating ring is positioned above the chassis 300. Further, the water ring can rotate about its axis so that its bottom lifts the water in the chassis 300. Of course, in order to enable the water-beating ring to rotate about its axis, the water distribution device 100 further comprises a driving assembly for driving the water-beating ring to rotate about its central axis. In this embodiment, the driving component may be an axial flow fan 60, the axial flow fan 60 includes a motor 61 and an axial flow wind wheel 63, and the water-beating ring is disposed around the outer edge of the axial flow wind wheel 63, when the axial flow fan 60 runs, the motor 61 drives the axial flow wind wheel 63 to rotate and drives the water-beating ring to rotate, so that the bottom of the water-beating ring can play up the water in the chassis 300. Of course, in other embodiments, the driving component may be the motor 61, and the water-spraying ring is directly sleeved on the output shaft of the motor 61, and when the motor 61 is operated, the motor 61 drives the water-spraying ring to rotate. Or a combination of the motor 61, the gear and the gear ring, wherein the gear ring can be arranged around the water ring along the circumferential direction of the water ring and is fixedly arranged on the water ring; the gear can be sleeved on the output shaft of the motor 61 and meshed with the gear ring; when the motor 61 is operated, the motor 61 drives the water-beating ring to rotate through the cooperation of the gear and the gear ring. Of course, those skilled in the art may implement other reasonable and effective embodiments according to the inventive concept, and will not be described in detail herein.

In addition, the water-beating structure 10 may be a water-beating plate, a water-beating wheel or other reasonable and effective water-beating structure. The corresponding driving assembly can adopt a crank rocker mechanism driven by a motor to enable one end of the strip-shaped water beating plate to swing highly, so as to contact and beat up water in the chassis 300; the rotation of the water-pumping wheel can also be directly driven by a motor, so that the outer edge of the water-pumping wheel contacts and pumps up the water in the chassis 300 during the rotation process. Of course, the driving components corresponding to the other water-beating structure 10 can be reasonably and effectively arranged, and will not be described in detail herein.

The water collecting structure 20 may be a plate-shaped structure to collect water using the lower surface thereof; a cover structure is also possible to collect water by its inner surface. The water collecting structure 20 is located in the first accommodating space 210 and above the water pumping structure 10, and is used for collecting water in the chassis 300 pumped by the water pumping structure 10 and guiding the collected water into the water distributing structure 30. The water distribution structure 30 is located above the heat exchanger 400, and the water distribution structure 30 may be a plate-shaped structure so as 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 drop to the heat exchanger 400; the water may be collected by using an inner space of the tray, the case, the tank, or the case, and then be dropped into the heat exchanger 400 by using an opening or a hole. The water may be directed to the heat exchanger 400 vertically from directly above the heat exchanger 400 or may be directed to the heat exchanger 400 obliquely from above the heat exchanger 400. Specifically, the water collecting structure 20 may be a plate-like structure which is disposed obliquely above the water beating structure 10 and the heat exchanger 400 with its plate surface at an angle to the horizontal plane, and whose plate surface height gradually decreases in a direction from the water beating structure 10 to the heat exchanger 400. The water distribution structure 30 may be disposed between the water collecting structure 20 and the heat exchanger 400, and is communicated with the water collecting structure 20 through flow guiding structures such as flow guiding pipes and flow guiding grooves; of course, the water distribution structure 30 may be arranged side by side with the water collection structure 20, i.e. the two structures have the same height. At this time, the lower surface of the plate-shaped structure may collect water in the bottom plate 300 lifted by the water-beating structure 10, and the collected water in the bottom plate 300 may flow along the lower surface of the plate-shaped structure to the water distribution structure 30, and flow from the water distribution structure 30 to the upper side of the heat exchanger 400, and finally drop over the upper side of the heat exchanger 400 to contact the heat exchanger 400, thereby completing the humidification process of the heat exchanger 400. Of course, a water baffle may be protruded towards the chassis 300 (downward) around the plate structure, so as to obtain a cover structure integrating the water collecting function and the water distributing function, thereby realizing water collection and water distribution with higher efficiency.

Therefore, it can be understood that in the technical solution of the present invention, by disposing the heat exchanger 400 and the water distribution device 100 in the first accommodating space 210 of the air conditioner outdoor unit 1000, and disposing the compressor assembly 500 in the second accommodating space 220, the compressor assembly 500 is separately and independently disposed from the heat exchanger 400 and the water distribution device 100, so that the respective operation reliability can be ensured. The water distribution device 100 comprises a water taking structure 10, a water collecting structure 20 and a water distribution structure 30, wherein the water taking structure 10 is arranged in the chassis 300, and water in the chassis 300 can be taken up by the water taking structure 10; then, the water collecting structure 20 is arranged above the water spraying structure 10, water sprayed by the water spraying structure 10 can be collected, and the collected water is guided into the water distribution structure 30; finally, the water distribution structure 30 is disposed above the heat exchanger 400, and is used for receiving water collected by the water collection structure 20, guiding the water to the heat exchanger 400, and completing the humidification process of the heater. In this way, the heat exchanger 400 obtains an additional humidification process besides using an air cooling mode, and can use water cooling to cool, so that the heat exchange efficiency is greatly improved, and the energy efficiency of the air conditioner outdoor unit 1000 is improved.

Referring to fig. 5, 17 and 18, the heat exchanger 400 has a linear structure or a bent structure. Referring to fig. 16, in an embodiment of the invention, the heat exchanger 400 is of a linear structure, and extends along the length direction of the water distribution structure 30, and the first accommodating space 210 is also of a linear structure corresponding to the cavity wall of the heat exchanger 400, so that the internal structure of the air conditioner outdoor unit 1000 is more compact.

Of course, in other embodiments, referring to fig. 18, the heat exchanger 400 has a bent structure, the heat exchanger 400 has a substantially L-shaped structure, and the first accommodating space 210 is also configured to have an L-shaped structure corresponding to the cavity wall of the heat exchanger 400, so that the internal structure of the air conditioner outdoor unit 1000 is more compact. The heat exchanger 400 is in an L-shaped structure, so that water flowing down from the water distribution holes 32 of the water distribution structure 30 can be more fully contacted with the heat exchanger 400, and the heat exchange efficiency of the heat exchanger 400 is further improved. It should be noted that the heat exchanger 400 may have a single-row structure, or may have a multi-row structure.

Alternatively, when the heat exchanger 400 is of a multi-row configuration, the size of the inner row heat exchanger is smaller than the size of the outer row heat exchanger. Referring to fig. 17 and 18, the heat exchanger 400 has a two-row structure, including a first row of heat exchangers 410 and a first row of heat exchangers 420 sequentially arranged outward along the width direction of the water distribution structure 30, wherein the size of the first row of heat exchangers 410 is smaller than that of the first row of heat exchangers 420, so that a part of water falling from the water distribution holes 32 directly flows to the first row of heat exchangers 410, and another part of water is blown to the second row of heat exchangers 420 by air flow, so that the water falling from the water distribution holes 32 is more fully contacted with the whole heat exchanger 400, thereby further improving the heat exchange efficiency of the heat exchanger 400. In this embodiment, referring to fig. 19, the first heat exchanger 410 is a linear heat exchanger, and the first heat exchanger 420 is a bent heat exchanger. Of course, in other embodiments, referring to fig. 20, the first row of heat exchangers 410 is a linear heat exchanger, and the second row is a linear heat exchanger.

The middle partition 330 is vertically disposed on the upper surface of the chassis 300 to divide the entire indoor space of the air-conditioning outdoor unit 1000 into the first and second receiving spaces 210 and 220, and the first and second receiving spaces 210 and 220 are sequentially disposed along the length direction thereof, thus making the arrangement of the internal parts of the air-conditioning outdoor unit 100 more compact. Optionally, the middle partition 330 is provided with a through hole, so that the air flow can pass through the through hole to effectively dissipate heat of the compressor assembly 500.

Of course, in other embodiments, the three components may be formed separately, and then mounted and fixed to each other by using a connecting structure (such as a buckle, a screw, etc.). In this way, the water diversion structure 10 is arranged in the air duct 51, and the water collection structure 20 and the water distribution structure 30 are positioned at the top of the air duct 51. At this time, a part of the water pumped by the water pumping structure 10 is collected and utilized by the water collecting structure 20, and the collected water is humidified by the top of the heat exchanger 400 through the water distribution structure 30, and the other part of the water is directly blown to the surface of the heat exchanger 400 by the air flow, so that the surface of the heat exchanger 400 is humidified, and the two parts are combined, so that the humidifying area is effectively increased, the humidifying efficiency is improved, the heat exchange efficiency of the heat exchanger 400 is greatly improved, and the energy efficiency of the air conditioner outdoor unit 1000 is improved.

Referring to fig. 5,6 and 10, in an embodiment of the present invention, a water storage tank 31 is concavely disposed on a surface of the water distribution structure 30 facing away from the heat exchanger 400, a water distribution hole 32 communicating with the water storage tank 31 is formed on a surface of the water distribution structure 30 facing the heat exchanger 400, a first flange 34 is circumferentially disposed on a bottom wall of the water storage tank 31 around the water distribution hole 32, and a height of the first flange 34 is lower than a height of a side wall of the water storage tank 31.

Specifically, the water distribution hole 32 is disposed right above the heat exchanger 400, and at this time, water in the water storage tank 31 of the water distribution structure 30 can directly drop to the upper surface of the heat exchanger 400 through the water distribution hole 32, so as to complete the humidifying process of the heat exchanger 400. The water collecting structure 20 is disposed adjacent to the water distributing structure 30, and is used for collecting water pumped by the water pumping structure 10 and guiding the collected water into the water storage tank 31 of the water distributing structure 30. Further, the water distribution hole 32 is circumferentially provided with a first flange 34, and the first flange 34 is in an annular structure, and the height of the first flange is lower than the height of the side wall of the water storage tank 31. At this time, the water guided into the water storage tank 31 by the water collecting structure 20 cannot leak down from the water distribution hole 32 at the first time, and needs to be accumulated in the water storage tank 31, so that the water level can leak down after rising to a height higher than the first flange 34, and impurities such as sediment in the water can be settled in the accumulating process of the water. That is, by utilizing the stop effect that the first flange 34 is higher than the bottom wall of the water storage tank 31, the water body in the water storage tank 31 can be subjected to the sedimentation process of impurities such as silt, so that the content of impurities in surface water in the water storage tank 31 is greatly reduced, the quantity of impurities such as silt which are contacted with the heat exchanger 400 along with water dripping is further reduced, the erosion and influence of the impurities such as silt on the heat exchanger 400 are reduced, and the heat exchange efficiency and the service life of the heat exchanger 400 are prevented from being influenced.

The water distribution structure 30 has the advantages of simple structure, convenient production and manufacture and higher reliability; meanwhile, the water distribution structure 30 of the structure greatly shortens the stroke of water drops before reaching the heat exchanger 400, avoids the loss of the water drops and the loss of cold, thereby effectively improving the heat exchange efficiency of the heat exchanger 400 and the energy efficiency of the air conditioner outdoor unit 1000.

It should be noted that, referring to fig. 10 and 11, the height of the first flange 34 is defined as H, which is not too high or too low: if the water level is too high, a large amount of water needs to be gathered in the water storage tank 31 to leak down through the water distribution holes 32, and at this time, a large amount of water cannot leak down, so that waste is formed, and a large amount of cold is lost; if too low, the sedimentation effect of impurities such as silt will be obviously reduced, and at this time, some impurities such as silt will leak down along with water drops to the heat exchanger 400, so that the heat exchanger 400 is corroded and affected, and the heat exchange efficiency and the service life of the heat exchanger 400 are affected. Therefore, in the present embodiment, the height H of the first flange 34 is designed to be in a range of not less than 3mm and not more than 6mm. It will be appreciated that in practice, the height H of the first flange 34 may be selected from 3mm, 3.1mm, 3.2mm, 3.3mm, 3.5mm, 4mm, 4.5mm, 5mm, or 6mm.

Meanwhile, referring to fig. 11, the pore diameter of the water distribution hole 32 is defined as D1, where D1 is not too large or too small: if the water is too large, the water in the water storage tank 31 leaks too quickly, so that the water is scattered without being fully contacted with the heat exchanger 400, and the cold is lost; if too small, the water in the water storage tank 31 leaks too slowly, so that the humidifying efficiency of the heat exchanger 400 is reduced, and the heat exchange efficiency of the heat exchanger 400 is reduced; in addition, the water distribution holes 32 have too small pore diameters, so that the water distribution holes 32 are easily blocked by impurities such as silt and the like, poor water leakage is caused, and the heat exchange efficiency of the heat exchanger 400 is weakened. Therefore, in this embodiment, the pore diameter D1 of the water distribution hole 32 is designed to be within a range of not less than 3mm and not more than 6mm. It will be appreciated that in practical applications, the diameter D1 of the water distribution holes 32 may be 3mm, 3.1mm, 3.2mm, 3.3mm, 3.5mm, 4mm, 4.5mm, 5mm or 6mm.

Referring to fig. 10 and 11 again, in an embodiment of the present invention, the surface of the water distribution structure 30 facing the heat exchanger 400 is further provided with an overflow hole 33 communicating with the water storage tank 31, the bottom wall of the water storage tank 31 is circumferentially provided with a second flange 35 around the overflow hole 33, and the height of the second flange 35 is higher than the height of the first flange 34 and lower than the height of the side wall of the water storage tank 31. It can be understood that if the water distribution hole 32 is blocked, the liquid level in the water storage tank 31 will be increased continuously; at this time, due to the arrangement of the overflow holes 33 and the second flanges 35, when the liquid level of the water body in the water storage tank 31 rises to be higher than the height of the second flanges 35, the water body can leak down from the overflow holes 33 and drop to the heat exchanger 400, so that the humidifying process of the heat exchanger 400 is realized, the situation that a large amount of cold energy is lost due to overflow of the water body from the side wall of the water storage tank 31 when the water distribution holes 32 are blocked is effectively avoided, the water distribution structure 30 can still normally operate when the water distribution holes 32 are blocked, humidification of the heat exchanger 400 is realized, the heat exchange efficiency of the heat exchanger 400 is improved, the energy efficiency of the air conditioner outdoor unit 1000 is improved, and meanwhile, the reliability of the water distribution device 100 is also improved.

It should be noted that, referring to fig. 11, the difference between the height of the second flange 35 and the height of the first flange 34 is defined as L, where L is not too large or too small: if the water distribution hole 32 is too large, when the water distribution hole 32 is blocked, the liquid level in the water storage tank 31 needs to be higher than the second flange 35 for a long time, so that a long-time gear interruption occurs, the heat exchanger 400 is not humidified, and the heat exchange efficiency is obviously reduced; moreover, when L is too large, a large amount of water is accumulated in the water storage tank 31, so that on one hand, the large amount of water cannot leak down and can cause cold energy loss, and on the other hand, the large amount of water is too large in weight and affects the stability of the water distribution structure 30; if too small, when the water collecting efficiency of the water collecting structure 20 is increased, the liquid level in the water storage tank 31 is easily higher than the second flange 35, so that the water distribution holes 32 and the overflow holes 33 leak water at the same time, and the water leaks too much, which causes the water to be scattered without being fully contacted with the heat exchanger 400, and causes the loss of cold. Therefore, in the present embodiment, the difference L between the height of the second flange 35 and the height of the first flange 34 is designed to be within a range of not less than 5mm and not more than 8mm. It will be appreciated that in practical applications, the difference L between the height of the second flange 35 and the height of the first flange 34 may be 5mm, 5.1mm, 5.2mm, 5.3mm, 5.5mm, 6mm, 6.5mm, 7mm or 8mm.

Further, the water distribution holes 32 are provided with a plurality of water distribution holes 32, and the plurality of water distribution holes 32 are arranged at intervals along the length direction of the water distribution structure 30. At this time, the overflow holes 33 are also provided with a plurality of water distribution holes 32, but the number of the overflow holes is less than that of the water distribution holes 32, and each overflow hole 33 is arranged between two adjacent water distribution holes 32; and the aperture of the overflow hole 33 is larger than that of the water distribution hole 32; thus, when the water distribution holes 32 are blocked, the overflow holes 33 can play an effective role in guiding flow, so that the water body is guided to the heat exchanger 400, and the normal operation of the water distribution structure 30 is ensured.

Referring to fig. 7 to 9, in an embodiment of the invention, the water collecting structure 20 includes a baffle 21, the baffle 21 is obliquely disposed above the water spraying structure 10, the baffle 21 includes a first side and a second side disposed opposite to each other, the second side is higher than the first side, and the first side is higher than the water distributing structure 30 and is located in the range of the water distributing structure 30.

Specifically, the second side of the deflector 21 is higher than the first side thereof, and the first side of the deflector 21 is higher than the water distribution structure 30 and is located within the range of the notch of the water storage tank 31 of the water distribution structure 30. At this time, the lower surface of the deflector 21 may collect water beaten up by the water beating structure 10; thereafter, the portion of the collected water may flow along the lower surface of the baffle 21 and to the first side of the baffle 21 in a direction from the second side to the first side; then, the water drops from the first side of the deflector 21 into the water storage tank 31 of the water distribution structure 30. The water collecting structure 20 is arranged in this way, and has the advantages of simple structure, convenient production and manufacture, high water collecting efficiency and high reliability. And well matched with the water distribution structure 30, the effect of quickly guiding the water to the water distribution structure 30 can be realized, so that the heat exchange efficiency of the heat exchanger 400 is further improved, and the energy efficiency of the air conditioner outdoor unit 1000 is improved.

It should be noted that, the angle between the baffle 21 and the horizontal plane should not be too large or too small: if the inclination angle of the deflector 21 is too large, the overall height of the water distribution device 100 will be too high, so that the air conditioner outdoor unit 1000 is bulky and inconvenient to install; if the inclination angle of the baffle 21 is too small, the water drops on the lower surface thereof will flow very slowly, and it is difficult to guide the water distribution structure 30, so that the water distribution structure 30 lacks water, and the water is difficult to reach the heat exchanger 400. Therefore, in the present embodiment, the angle between the baffle 21 and the horizontal plane is designed to be within the range of not less than 5 ° and not more than 30 °. It will be appreciated that in practical applications, the angle between the baffle 21 and the horizontal plane may be 5 °, 6 °, 7 °, 8 °, 10 °,15 °, 20 °, or 30 °.

It can be appreciated that the arrangement of the first baffle 22 can stop the part of the splash water formed by the water sprayed by the water spraying structure 10 impacting the lower surface of the deflector 21, so that the part of splash water can smoothly enter the water storage tank 31 of the water distribution structure 30 along the surface of the first baffle 34, thereby improving the water collecting efficiency of the water collecting structure 20, reducing the cold energy loss caused by water splashing, and improving the heat exchange efficiency of the heat exchanger 400. Likewise, the water collecting structure 20 further includes a second baffle 23 disposed at the second side, the second baffle 23 being disposed vertically with its lower side disposed toward the chassis 300. It can be appreciated that the second baffle 23 can stop the part of the splash water formed by the water sprayed by the water spraying structure 10 after impacting the lower surface of the guide plate 21, so that the part of splash water flows down along the surface of the second baffle 23 and returns to the chassis 300 to be recycled and collected, thereby reducing the loss of cold energy caused by water splashing and improving the heat exchange efficiency of the heat exchanger 400.

It will be appreciated that the baffle 21 of the water collecting structure 20 is obliquely disposed above the water permeable opening 41, and at this time, the water pumped up by the water pumping structure 10 passes through the water permeable opening 41 to reach the lower surface of the baffle 21, flows along the lower surface of the baffle 21 to the upper side of the water distributing structure 30, and then drops from the upper side of the water distributing structure 30 to enter the water distributing structure 30.

The width of the water permeable opening 41 covers the width of the water beating structure 10 in the vertical direction. Therefore, the probability that water beaten by the water beating structure 10 passes through the water permeable opening 41 and reaches the lower surface of the guide plate 21 can be improved, the water quantity entering the water distribution structure 30 is improved, the humidification quantity of the heat exchanger 400 is improved, the cold energy loss is reduced, and the heat exchange efficiency is improved. Further, referring to fig. 6, a horizontal spacing W between the width edges of the water permeable opening 41 opposite to the width edges of the water beating structure 10 is defined, wherein W is not too small or too large: if the width of the water permeable opening 41 is too small, the amount of water passing through the water permeable opening 41 and reaching the lower surface of the guide plate 21 is too small, the cooling capacity loss is too large, and the heat exchange efficiency improving effect is obviously reduced; if the width of the water permeable opening 41 is too large, the water distribution device 100 becomes thick, the air treatment device becomes thick and is inconvenient to install, the width of the guide plate 21 becomes large, the inclination angle is reduced, the guide effect is poor, the water quantity in the water distribution structure 30 is affected, the cold energy loss is caused, and the heat exchange efficiency is obviously improved.

It will be appreciated that in practice, the spacing W in the horizontal direction of the width edge of the watering structure 10 from the width edge of the water permeable opening 41 opposite thereto may be selected to be 10mm, 11mm, 12mm, 13mm, 15mm, 20mm, 30mm or 45mm.

Referring to fig. 6 and 7, in an embodiment of the present invention, a plugging slot 231 is formed on a side of the second baffle 23 facing away from the baffle 21, a shroud 42 is protruding towards the plugging slot 231 on a side of the water permeable opening 41, and a side of the shroud 42 facing away from the water permeable opening 41 is plugged into the plugging slot 231.

Further, a seal (not shown) is provided in the insertion groove 231, and the seal abuts against the groove wall of the insertion groove 231 and the surface of the shroud 42 inserted in the insertion groove 231, respectively. Thus, by using the sealing member, the gap between the groove wall of the insertion groove 231 and the surface of the coaming 42 inserted in the insertion groove 231 can be effectively sealed, and water is prevented from flowing out of the gap, so that leakage of water is reduced, and loss of cold is reduced.

Because part of water drops can splash and be adhered to the lower surface of the water collecting structure 20 above the water taking structure 10 in the movement process of the water taking structure 10 after water is taken up, the water taking structure 10 is low in normal temperature when taken up from the chassis 300, particularly when taken up water is condensed water formed on the surface of the heat exchanger 400, the lower surface of the water collecting structure 20 is close to one side of the heat exchanger 400, the air temperature at the side is low after the heat exchange of the heat exchanger 400, and therefore, after air with high temperature at the side of the water collecting structure 20 away from the water taking structure 10 encounters cold, the air is easy to condense to form secondary condensed water. In this embodiment, collect the utilization to secondary condensate through water collecting structure 80, effectively prevent the inside ponding of air treatment device, water economy resource. Specifically, the water collecting structure 80 may be a plate-shaped structure to receive the collected water by its upper surface, and then the water flows to the edge along its upper surface to drop toward the water distributing structure 30; the water distribution structure 30 may be a tray structure, a box structure, a tank structure, or a box structure, in which collected water is received by using an internal space, and then water drops are distributed to the water distribution structure 30 by using openings or holes.

Referring to fig. 2 and 3, in an embodiment of the present invention, a water collecting tank 81 is disposed on a surface of the water collecting structure 80 facing away from the water distribution structure 30, a water collecting tank 20a is disposed on a side of the water collecting structure 20 facing away from the water pumping structure 10, and the water collecting tank 81 is communicated with the water collecting tank 20 a.

Specifically, the water collecting tank 81 may be a recess formed on the upper surface of the water collecting structure 80, the water collecting tank 20a is a recess formed on the upper surface of the water collecting structure 20, i.e. the surface facing away from the water pumping structure 10, and when the condensed water is generated on the upper surface of the water collecting structure 20, the condensed water is firstly contained in the water collecting tank 20a, and then flows from the water collecting tank 20a to the water collecting tank 811 to return to the water distribution structure 30 again for humidifying the heat exchanger 400. Therefore, the full utilization of the secondary condensation water is realized, the energy is saved, and the phenomenon of running, falling and leaking can not occur in the whole utilization process of the secondary condensation water. In this embodiment, the water collecting structure 20 is connected to a side wall of the water collecting structure 80 to form an integral structure, and the side wall is formed as a common groove wall of the water collecting groove 20a and the water collecting groove 81, and the common groove wall is provided with the water guide 82, so that the condensed water in the water collecting groove 20a can flow into the water collecting groove 81 through the water guide 82. The water guiding port 82 may be a notch on the slot wall, and the shape may be designed into a U shape or other special shapes, and of course, the water guiding port 82 may also be a through hole on the slot wall. The number of water guiding ports 82 may be designed according to the actual amount of the condensed water, for example, one, two or three or more. The water guide port 82 is formed in the side wall of the water collecting tank 81 and is directly communicated with the water collecting tank 20a, so that the stroke of secondary condensation water drops before reaching the heat exchanger 400 is greatly shortened, the loss of the secondary condensation water drops is avoided, the loss of cold is avoided, the heat exchange efficiency of the heat exchanger 400 is effectively improved, and the energy efficiency of the air conditioner outdoor unit 1000 is improved.

Referring to fig. 3 and 5, in an embodiment of the present invention, a drain hole 83 communicating with the water distribution structure 30 is formed in a wall of the water collecting tank 81.

Specifically, the drain hole 83 is formed in the bottom wall of the water collecting tank 81 and located above the water distribution structure 30, at this time, water in the water collecting tank 81 can be directly dripped into the water distribution structure 30 through the drain hole 83, and then is guided to the heat exchanger 400 by the water distribution structure 30. Alternatively, a plurality of drain holes 83 are provided, and the plurality of drain holes 83 are provided at intervals along the length direction of the water trap 81; correspondingly, the surface of the water distribution structure 30 facing the heat exchanger 400 is provided with a plurality of water distribution holes 32, and one water discharge hole 83 and one water distribution hole 32 are arranged in a staggered manner. In this way, in the process that water in the water collecting tank 81 flows into the water distribution structure 30 through the water discharge holes 83 arranged at intervals, because the corresponding water discharge holes 83 and the water distribution holes 32 are arranged in a staggered manner, the water flowing down from the water discharge holes 83 does not directly enter the water distribution holes 32 from the water discharge holes 83 and is dripped into the heat exchanger 400, but is uniformly distributed in the water distribution structure 30, water is uniformly distributed in the water distribution structure 30, and is uniformly dripped into the heat exchanger 400 from the plurality of water distribution holes 32, so that a spraying effect on heat exchange is realized, the humidifying efficiency of the heat exchanger 400 is greatly improved, and the heat exchange efficiency is improved.

Further, referring to fig. 3 and 4, in an embodiment of the invention, a third flange 85 is disposed around the drain hole 83, and the height of the third flange 85 is lower than the height of the wall of the water collecting tank 81. The third flange 85 is an annular structure and is arranged around the periphery of the drain hole 83, and the shape of the third flange can be a circular flange or a square flange, in practical application, due to the arrangement of the third flange 85, the condensed water flows into the water collecting tank 81, so that impurities such as sediment in the condensed water can be deposited at the bottom of the water collecting tank 81, and after the water level in the condensed water flowing into the water collecting tank 81 exceeds the height of the third flange 85, relatively clear water on the upper part of the condensed water flows into the water distribution structure 30 from the drain hole 83. It can be appreciated that the third flange 85 is designed to enable impurities such as sediment in the condensed water to be deposited, so as to ensure that the drain hole 83 is not blocked; meanwhile, the content of impurities in surface water flowing into the water storage tank 31 from the drain holes 83 can be greatly reduced, so that the quantity of impurities such as sediment which is in contact with the heat exchanger 400 along with water dripping is reduced, the erosion and influence of the impurities such as sediment on the heat exchanger 400 are reduced, and the heat exchange efficiency and the service life of the heat exchanger 400 are prevented from being influenced.

It should be noted that, referring to fig. 4, the height of the third flange 85 is defined as h1, where h1 is not too high or too low: if the water level in the water collecting tank 81 is too high, a large amount of condensed water is generated, and overflows from the water collecting tank 81 easily, so that inconvenience is brought to a user; if too low, sediment and impurities in the condensed water are not easy to deposit, so that the content of impurities in the surface water flowing into the water storage tank 31 from the drain holes 83 is increased, and the quantity of impurities such as sediment contacted with the heat exchanger 400 along with the leakage of water drops is increased, and the heat exchange efficiency and the service life of the heat exchanger 400 are affected. Of course, the aperture of the drain hole 83 should not be too large nor too small as well: if the water is too large, splashing is easily caused in the drainage process, water is wasted, and if the water is too small, overflow is easily caused by insufficient drainage flow when a large amount of condensed water is generated. Therefore, in the present embodiment, the height of the third rib 85 is designed to be in a range of not less than 5mm and not more than 8mm, and the aperture of the drain hole 83 is designed to be in a range of not less than 8mm and not more than 15mm. It will be appreciated that in practice, the height of the third flange 85 may be 5mm, 6mm, 6.5mm, 7mm or 8mm. The aperture of the drain hole 83 may be 8mm, 10mm, 12mm, 14mm, or 15mm.

Further, referring to fig. 3 again, in an embodiment of the present application, the water collecting tank 81 is further provided with an overflow hole 84 communicated with the water distribution structure 30, a fourth flange 86 is circumferentially disposed around the overflow hole 84, and the height of the fourth flange 86 is lower than the depth of the water collecting tank 81 and higher than the height of the third flange 85. It will be appreciated that if the drain hole 83 is blocked, the liquid level in the sump 81 will be continually raised; at this time, due to the arrangement of the overflow holes 84 and the fourth ribs 86, when the liquid level of the water body in the water collecting tank 81 rises to a height higher than that of the fourth ribs 86, the water can flow into the water distribution structure 30 through the overflow holes 84, so that the situation that a large amount of cold energy is lost due to the overflow of secondary condensation water from the side wall of the water collecting tank 81 when the drain holes 83 are blocked is effectively avoided, the water collecting structure 80 can still normally operate when the drain holes 83 are blocked, and the reliability of the water distribution device 100 is improved.

It should be noted that, referring to fig. 4 again, defining the height of the fourth flange 86 as h2, the relationship is satisfied: h2 is more than or equal to 10mm and less than or equal to 16mm; defining the pore diameter of the overflow hole 84 as d2, the relationship is satisfied: d2 is more than or equal to 13mm and less than or equal to 24mm.
