Specifically, the water distribution holes 32 are disposed right above the heat exchanger 400, and at this time, water in the water storage tank 31 of the water distribution structure 30 may directly drop to the upper surface of the heat exchanger 400 through the water distribution holes 32, thereby completing the humidification process of the heat exchanger 400. And, the water collecting structure 20 is disposed adjacent to the water distributing structure 30, and is used for collecting the 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. Furthermore, a first rib 34 is arranged around the water distribution hole 32, and the first rib 34 is of an annular structure and is lower than the side wall of the water storage tank 31. At this time, the water introduced into the water storage tank 31 by the water collection structure 20 cannot leak down through the water distribution holes 32 in the first time, and needs to be accumulated in the water storage tank 31, so that the water can leak down after the liquid level rises to a height higher than the first rib 34, and impurities such as silt in the water can be settled in the accumulation process of the water. That is, utilize first flange 34 to be higher than 31 diapalls of aqua storage tank and the backstop effect that takes place, can make the water in the aqua storage tank 31 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 31, and then reduce along with the water droplet leak down and with the quantity of impurity such as silt of heat exchanger 400 contact, reduce the erosion and the influence of impurity such as silt to heat exchanger 400, avoid heat exchange efficiency and the life of heat exchanger 400 to be influenced.

The water distribution structure 30 has such a simple structure, is convenient to produce and manufacture and has high reliability; meanwhile, the water distribution structure 30 of this structure greatly shortens the travel of water droplets before reaching the heat exchanger 400, avoids the loss of water droplets, and avoids the loss of cooling capacity, thereby effectively improving the heat exchange efficiency of the heat exchanger 400 and improving the energy efficiency of the outdoor unit 1000 of the air conditioner.

It should be noted that, referring to fig. 10 and 11, the height of the first rib 34 is defined as H, H should not be too high, and should not be too low: if the height is too high, a large amount of water needs to be gathered in the water storage tank 31, and the water can leak through the water distribution holes 32, so that a large amount of water cannot leak, 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 400 along with the leakage of water drops, so as to erode and influence the heat exchanger 400, and thus the heat exchange efficiency and the service life of the heat exchanger 400 are influenced. Therefore, in the present embodiment, the height H of the first rib 34 is designed to be in a range of not less than 3mm and not more than 6 mm. It is understood that in practical applications, the height H of the first rib 34 may be 3mm, 3.1mm, 3.2mm, 3.3mm, 3.5mm, 4mm, 4.5mm, 5mm or 6 mm.

Meanwhile, referring to fig. 11, the aperture of the water distribution holes 32 is defined as D1, D1 should not be too large or too small: if the water volume is too large, the water in the water storage tank 31 leaks too fast, the water is not fully contacted with the heat exchanger 400 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 31 is too slow, the humidification efficiency of the heat exchanger 400 is reduced, and the improvement effect of the heat exchange efficiency of the heat exchanger 400 is weakened; in addition, the aperture of the water distribution holes 32 is too small, so that the water distribution holes 32 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 400 is weakened. Therefore, in this embodiment, the aperture D1 of the water distribution holes 32 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 32 may be 3mm, 3.1mm, 3.2mm, 3.3mm, 3.5mm, 4mm, 4.5mm, 5mm or 6 mm.

Referring to fig. 10 and 11 again, in an embodiment of the present invention, an overflow hole 33 communicating with the water storage tank 31 is further formed on a surface of the water distribution structure 30 facing the heat exchanger 400, a second rib 35 is disposed around the overflow hole 33 on a bottom wall of the water storage tank 31, and the height of the second rib 35 is higher than the height of the first rib 34 and lower than the height of a side wall of the water storage tank 31. It can be understood that if the water distribution holes 32 are blocked, the liquid level in the water storage tank 31 will rise continuously; at this time, the arrangement of the overflow holes 33 and the second ribs 35 can make the water in the water storage tank 31 leak down from the overflow holes 33 and drip toward the heat exchanger 400 when the liquid level rises to a height higher than the second ribs 35, so as to realize the humidification process of the heat exchanger 400, thereby effectively avoiding the situation that the water overflows from the side wall of the water storage tank 31 when the water distribution holes 32 are blocked, so as to cause a large amount of loss of cold energy, making the water distribution structure 30 still normally operate when the water distribution holes 32 are blocked, realizing the humidification of the heat exchanger 400, improving the heat exchange efficiency of the heat exchanger 400, improving the energy efficiency of the air conditioner outdoor unit 1000, and also improving the reliability of the water distribution device 100.

Please refer to fig. 11, the difference between the height of the second rib 35 and the height of the first rib 34 is defined as L, and L should not be too large or too small: if the height is too large, when the water distribution holes 32 are blocked, the liquid level in the water storage tank 31 needs to be higher than the second baffle 35 for a long time, so that the baffle is broken for a long time, the heat exchanger 400 is not humidified during the process, and the heat exchange efficiency is obviously reduced; moreover, if L is too large, a large amount of water bodies will be gathered in the water storage tank 31, on one hand, a large amount of water bodies cannot leak down, which will cause loss of cooling capacity, and on the other hand, the weight of a large amount of water bodies is too large, which will affect the stability of the water distribution structure 30; if the water quantity is too small, when the water collection efficiency of the water collection structure 20 is accelerated, the liquid level in the water storage tank 31 is easily higher than the second rib 35, and the water distribution holes 32 and the overflow holes 33 leak water at the same time, so that the water body leaks too much, and the water body is not fully contacted with the heat exchanger 400 and flows and scatters, and the loss of cold quantity is caused. Therefore, in the present embodiment, the difference L between the height of the second rib 35 and the height of the first rib 34 is designed to be in the range of not less than 5mm and not more than 8 mm. It is understood that in practical applications, the difference L between the height of the second rib 35 and the height of the first rib 34 may be 5mm, 5.1mm, 5.2mm, 5.3mm, 5.5mm, 6mm, 6.5mm, 7mm or 8 mm.

Furthermore, a plurality of water distribution holes 32 are provided, and a plurality of water distribution holes 32 are arranged at intervals along the length direction of the water distribution structure 30. At this time, a plurality of overflow holes 33 are also arranged, but the number of the overflow holes 33 is less than that of the water distribution holes 32, and each overflow hole 33 is arranged between two adjacent water distribution holes 32; 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 flow guiding role, ensure that the water body is guided to the heat exchanger 400, and ensure the normal operation of the water distribution structure 30.

Referring to fig. 7 to 9, in an embodiment of the present invention, the water collecting structure 20 includes a guide plate 21, the guide plate 21 is disposed above the water fetching structure 10 in an inclined manner, the guide plate 21 includes a first side and a second side which are disposed oppositely, the second side is higher than the first side, and the first side is higher than the water distributing structure 30 and is located within a range of the water distributing structure 30.

Specifically, the second side of the baffle 21 is higher than the first side thereof, and the first side of the baffle 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 guide plate 21 can collect the water kicked up by the water kicking structure 10; then, the part of the collected water can flow to the first side of the baffle 21 along the lower surface of the baffle 21 and in the direction from the second side to the first side; then, the water drops from the first side of the baffle 21 into the water storage tank 31 of the water distribution structure 30. The arrangement of the water collecting structure 20 is simple in structure, convenient to produce and manufacture, high in water collecting efficiency and high in reliability. And, with the water distribution structure 30 cooperation well, can realize the effect to the quick water conservancy diversion of water distribution structure 30 to further promote the heat exchange efficiency of heat exchanger 400, promote the efficiency of air condensing units 1000.

It should be noted that the included angle between the guide plate 21 and the horizontal plane should not be too large or too small: if the inclination angle of the guide plate 21 is too large, the overall height of the water distribution device 100 will be too high, and the outdoor unit 1000 of the air conditioner will have a large volume and is inconvenient to install and install; if the inclination angle of the deflector 21 is too small, the flow of water droplets on the lower surface thereof is very slow, and the water droplets are difficult to be introduced into 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 this embodiment, the angle between the baffle 21 and the horizontal plane is set to be not less than 5 ° and not more than 30 °. It can be understood that, in practical applications, the included angle between the baffle 21 and the horizontal plane may be selected from 5 °, 6 °, 7 °, 8 °, 10 °, 15 °, 20 °, or 30 °.

Further, a first baffle 22 is protruded from the first side edge toward the water distribution structure 30, and a second baffle 23 is protruded from the second side edge toward the chassis 300.

Specifically, the water collecting structure 20 further includes a first baffle 22 disposed at the first side edge, the first baffle 22 is disposed vertically and extends toward the water storage tank 31 of the water distributing structure 30, and optionally, one side of the first baffle 22 facing away from the baffle 21 extends into the water outlet tank. It can be understood that the first baffle 22 is disposed to prevent part of the splashed water formed by the water kicked by the water kicking structure 10 striking the lower surface of the guide plate 21, so that the part of the splashed water can smoothly enter the water storage tank 31 of the water distribution structure 30 along the surface of the first rib 34, thereby improving the water collection efficiency of the water collection structure 20, reducing the loss of cooling capacity caused by splashing of the water, 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 a second side, the second baffle 23 being vertically disposed with its lower side disposed toward the bottom plate 300. It can be understood that the second baffle 23 is arranged to stop part of the splashed water formed after the water kicked up by the water kicking structure 10 hits the lower surface of the guide plate 21, so that the part of the splashed water can flow down along the surface of the second baffle 23 and return to the chassis 300 to be recycled and collected, thereby reducing the loss of cooling capacity caused by splashing of the water body and improving the heat exchange efficiency of the heat exchanger 400.

Referring to fig. 5 to 7, in an embodiment of the present invention, the water distribution device 100 further includes a frame 40 surrounding the water distribution structure 30, a water permeable opening 41 is formed on a surface of the frame 40 facing the water fetching structure 10, and the water collecting structure 20 is disposed above the water permeable opening 41 and connected to the frame 40. So, realized that water collecting structure 20 is fixed in the installation of frame 40, promoted water collecting structure 20 set up stability, ensured water collecting structure 20 and water distribution structure 30's effective cooperation, promoted the two complex reliability to effectively ensured the stability and the reliability of water distribution device 100, ensured heat exchanger 400's humidification effect, ensured heat exchanger 400's heat exchange efficiency's promotion effect. It can be understood that the diversion plate 21 of the water collection structure 20 is obliquely disposed above the water permeable port 41, and at this time, the water pumped by the water pumping structure 10 passes through the water permeable port 41 to reach the lower surface of the diversion plate 21, and flows along the lower surface of the diversion plate 21 to the upper side of the water distribution structure 30, and then drops from the upper side of the water distribution structure 30 to enter the water distribution structure 30.

Note that, the width range of the water penetration port 41 covers the width range of the water beating structure 10 in the vertical direction. Therefore, the probability that water pumped by the water pumping structure 10 passes through the water permeable port 41 and reaches the lower surface of the guide plate 21 can be improved, the amount of water entering the water distribution structure 30 is improved, the humidification amount of the heat exchanger 400 is increased, the cold loss is reduced, and the heat exchange efficiency is improved. Referring to fig. 6, a horizontal distance W between the width edge of the water inlet 41 and the width edge of the water outlet structure 10 is defined, W should not be too small or too large: if the water quantity is too small, the width of the water permeable port 41 is too small, the water quantity passing through the water permeable port 41 and reaching the lower surface of the guide plate 21 is too small, the cold quantity loss is too large, and the heat exchange efficiency improvement effect is obviously reduced; if too big, then the width of mouth 41 of permeating water is too big, not only can make the whole thickening of water distribution device 100 for the air treatment device thickening, inconvenient settling and installation, but also can make the width grow of guide plate 21, inclination descends, and the water conservancy diversion effect variation, thereby influences the water yield in the water distribution structure 30, causes the cold volume loss, and heat exchange efficiency's promotion effect will obviously reduce. Therefore, in the present embodiment, the distance W in the horizontal direction between the width edge of the water discharging structure 10 and the width edge of the water permeable port 41 opposite thereto is set to be not less than 10mm and not more than 45 mm. It is understood that in practical applications, the distance W between the width edge of the water spraying structure 10 and the width edge of the water penetration port 41 opposite to the width edge in the horizontal direction can be selected to be 10mm, 11mm, 12mm, 13mm, 15mm, 20mm, 30mm or 45 mm.

Referring to fig. 6 and 7, in an embodiment of the present invention, an insertion groove 231 is formed on a side of the second baffle 23 away from the guide plate 21, a surrounding plate 42 is protruded from a side of the water permeable opening 41 toward the insertion groove 231, and a side of the surrounding plate 42 away from the water permeable opening 41 is inserted into the insertion groove 231.

Specifically, a first connecting plate 232 is convexly arranged on the side of the second baffle 23 away from the guide plate 21 toward the chassis 300, a second connecting plate 233 is convexly arranged on the side of the second baffle 23 away from the guide plate 21, a third connecting plate 234 is convexly arranged on the side of the second connecting plate 233 away from the second baffle 23 toward the chassis 300, and the first connecting plate 232, the second connecting plate 233 and the third connecting plate 234 are enclosed to form the insertion groove 231. The side of mouth 41 that permeates water is equipped with bounding wall 42 towards the inserting groove 231 is protruding, and the top of bounding wall 42 is pegged graft in inserting groove 231, so, simple structure, manufacturing convenience to can make bounding wall 42 and second baffle 23's connection stability promote. In addition, due to the design, the splashing water stopped by the inner wall surface of the second baffle plate 23 is not blocked by other structures in the flowing process, so that the splashing water can smoothly flow back to the ground floor 300 to realize circulation, the cold loss caused by splashing of the water body is reduced, the heat exchange efficiency of the heat exchanger 400 is improved, and the energy efficiency of the air conditioner outdoor unit 1000 is improved. Of course, in other embodiments, the top of the enclosing plate 42 is connected to the second baffle 23, and may be realized by means of a snap connection, a screw connection, or the like.

Further, a sealing member is disposed in the insertion groove 231, and the sealing member abuts against a groove wall of the insertion groove 231 and a surface of the surrounding plate 42 inserted in the insertion groove 231. Thus, by using the sealing member, the gap between the wall of the insertion groove 231 and the surface of the enclosing plate 42 inserted into the insertion groove 231 can be effectively sealed, and water is prevented from flowing out from the gap, thereby reducing the leakage of the water body and reducing the loss of the cooling capacity. That is, the water collecting efficiency and the water collecting amount of the water collecting structure 20 are improved, the amount of water entering the water distributing structure 30 is improved, the cooling capacity obtained by the heat exchanger 400 is improved, the heat exchange efficiency of the heat exchanger 400 is improved, and the energy efficiency of the outdoor unit 1000 of the air conditioner is improved.

Referring to fig. 1 to fig. 3 again, in an embodiment of the present invention, the water distribution device 100 further includes a water collecting structure 80, the water collecting structure 80 is disposed on a side of the water distribution structure 30 away from the heat exchanger 400, and is used for collecting the condensed water on a side of the water collecting structure 20 away from the water fetching structure 10 and guiding the condensed water into the water distribution structure 30.

Because in the motion process after beating the structure 10 of fetching water, some water droplets can splash and be stained with on the water collection structure 20 lower surface of beating the structure 10 top of fetching water, because the water that beats structure 10 from chassis 300 is all lower in temperature usually, especially when the water that beats is the comdenstion water that the heat exchanger 400 surface formed, water collection structure 20 lower surface is close to one side of heat exchanger 400, after the heat exchanger 400 heat transfer, this side air temperature is also lower, the higher air of the side temperature that deviates from beating the structure 10 of fetching water of structure 20 like this meets the cold back, the easy condensation forms the secondary condensate water. In this embodiment, collect the utilization through water collecting structure 80 to the secondary condensate water, effectively prevent the inside ponding of air treatment device, the water economy resource. Specifically, the water collecting structure 80 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 dripped to the water distributing structure 30; or a tray structure, a box structure, a trough structure or a box structure, so as to utilize the inner space thereof to receive the collected water, and then utilize the opening or the hole to drip the water to the water distribution structure 30. The water collecting structure 80 is connected with one side of the water collecting structure 20, which is far away from the water pumping structure 10, and can be connected through a communicating pipe, a communicating groove and other structures, or can be connected with the water collecting and distributing structure 30 and then connected through structures such as a communicating port, a communicating hole and the like, so that the condensed water can be gathered in the water collecting structure 80 through the surface of the water collecting structure 20, which is far away from the water pumping structure 10, and then is guided back to the water distributing structure 30 from the water collecting structure 80, so that the condensed water can be used by the heat exchanger 400. Certainly, the water collecting structure 80 may be connected with the water collecting structure 20 to form an integral structure, and then fixed with the side of the water distributing structure 30 away from the heat exchanger 400 by welding or screwing, which is a common connection method in the art. So, be convenient for switch on catchment structure 20 and water collecting structure 80, needn't design complicated conduction structure, simultaneously, can reduce the degree of difficulty of manufacturing, promote the efficiency of manufacturing, still realized dismantling each other between the part moreover, promoted the convenience of changing the maintenance, promoted the practicality of product.

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

Specifically, the water collecting groove 81 may be a recess formed on the upper surface of the water collecting structure 80, and the water collecting groove 20a is a recess formed on the upper surface of the water collecting structure 20, i.e. the surface facing away from the water fetching structure 10, 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 groove 20a, and then flows from the water collecting groove 20a to the water collecting groove 811 to return to the water distributing structure 30 again for humidifying the heat exchanger 400. So, realize the make full use of to the secondary condensate water, the energy saving to, to the whole utilization in-process of secondary condensate water, the phenomenon that the leakage that appears running and reporting to the police can not appear. 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 wall of the water collecting tank 20a and the water collecting tank 81, and the common wall is provided with the water guiding opening 82, so that the condensed water in the water collecting tank 20a can flow into the water collecting tank 81 through the water guiding opening 82. The water guiding opening 82 may be a notch on the wall of the tank, and the shape may be designed to be "U" or other special shapes, of course, the water guiding opening 82 may also be a through hole on the wall of the tank. The number of water guiding openings 82 may then be designed according to the actual amount of condensed water, e.g. one, two or three, or even more. The water guide opening 82 is formed in the side wall of the water collecting groove 81 and is directly communicated with the water collecting groove 20a, so that the stroke of the secondary condensed water drops before reaching the heat exchanger 400 is greatly shortened, the loss of the secondary condensed water drops is avoided, the loss of cold energy 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 water drainage hole 83 is formed on a wall of the water collection tank 81 and is communicated with the water distribution structure 30.

Specifically, the drain hole 83 is opened on 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 directly drop 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, so that the structure setting is simpler, the production and the manufacture are convenient, and the reliability is higher. 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 collecting tank 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 a water discharge hole 83 is arranged in a staggered manner with respect to one water distribution hole 32. So, the in-process that the water in the water collecting tank 81 flows into the water distribution structure 30 through the drain hole 83 that the interval set up, because the drain hole 83 that corresponds sets up with the dislocation of water distribution hole 32, then water that flows down from the drain hole 83 can not directly get into in the water distribution hole 32 and drip to the heat exchanger 400 from the drain hole 83, but evenly distributed earlier in the water distribution structure 30, evenly distributed in the water distribution structure 30, just later evenly drip to the heat exchanger 400 from a plurality of water distribution holes 32, just so realize forming the spraying effect to the heat transfer, the efficiency of humidifying heat exchanger 400 has been improved greatly, thereby its heat exchange efficiency has been promoted.

Further, referring to fig. 3 and 4, in an embodiment of the present invention, a third rib 85 is disposed around the drain hole 83, and the height of the third rib 85 is lower than the height of the trough wall of the water collecting trough 81. Third flange 85 is the loop configuration, encloses the periphery of locating wash port 83, and its shape can be circular flange, also can be square flange, and in practical application, because the setting of third flange 85, the condensate flows into earlier in gathering water tank 81, makes like this impurity such as silt in the condensate can deposit in the bottom of gathering water tank 81, and after the water level that the condensate flowed into in gathering water tank 81 exceeded the height of third flange 85, the clear water of condensate upper portion can flow into in water distribution structure 30 from wash port 83. It can be understood that the third blocking edge 85 is designed to enable impurities such as silt 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 water discharge holes 83 can be greatly reduced, the amount of impurities such as silt contacting the heat exchanger 400 along with the leakage of water drops is reduced, the erosion and influence of the impurities such as silt on the heat exchanger 400 are reduced, and the influence on the heat exchange efficiency and the service life of the heat exchanger 400 is avoided.

It should be noted that, referring to fig. 4, the height of the third rib 85 is defined as h1, and h1 is not too high nor too low: if the water level in the water collection tank 81 is too high, the water level in the water collection tank 81 is high, and when a large amount of condensed water is generated, the condensed water is easy to overflow from the water collection tank 81, so that inconvenience is brought to a user; if the water content is too low, the sediment and impurities in the condensed water are not easy to be deposited, so that the content of the impurities in the surface water flowing into the water storage tank 31 through the water discharge hole 83 is increased, the amount of the impurities such as the sediment and the like contacting the heat exchanger 400 along with the leakage of the water drops is increased, and the heat exchange efficiency and the service life of the heat exchanger 400 are influenced. Of course, the diameter of the drain hole 83 should not be too large or too small: if too large, the phenomenon of splashing is easily caused in the drainage process, resulting in the waste of water, and if too small, the phenomenon of overflow is easily caused due to 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 hole diameter of the drain hole 83 is designed to be in a range of not less than 8mm and not more than 15 mm. It will be appreciated that in practice the height of the third rim 85 may be 5mm, 6mm, 6.5mm, 7mm or 8 mm. The hole diameter of the drain hole 83 may be 8mm, 10mm, 12mm, 14mm, or 15 mm.

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 distributing structure 30, a fourth rib 86 is disposed around the overflow hole 84, and a height of the fourth rib 86 is lower than a depth of the water collecting tank 81 and higher than a height of the third rib 85. It can be understood that if the drain hole 83 is blocked, the liquid level in the water collecting tank 81 will be raised continuously; at this time, the arrangement of the overflow holes 84 and the fourth ribs 86 enables the water in the water collecting tank 81 to flow into the water distributing structure 30 through the overflow holes 84 when the liquid level rises to a height higher than the fourth ribs 86, thereby effectively avoiding the situation that a large amount of cold energy is lost due to the overflow of secondary condensed water from the side wall of the water collecting tank 81 when the water discharge holes 83 are blocked, enabling the water collecting structure 80 to still normally operate when the water discharge holes 83 are blocked, and improving the reliability of the water distributing device 100.

Please refer to fig. 4 again, if the height of the fourth rib 86 is defined as h2, the relationship is satisfied: h2 is more than or equal to 10mm and less than or equal to 16 mm; the aperture of the overflow hole 84 is defined as d2, the relationship: d2 is more than or equal to 13mm and less than or equal to 24 mm. Specifically, the height of the fourth rib 86 may be 10mm, 11mm, 12mm, 13mm, 14mm, or 16 mm. The diameter of the overflow hole 84 may be 13mm, 15mm, 17mm, 20mm, 22mm or 24 mm. The diameter of the overflow hole 84 is designed to be slightly larger than that of the drain hole 83, which is beneficial to quickly draining the water in the water collecting tank 81 when the drain hole 83 is blocked, and the height of the fourth rib 86 is lower than the depth of the water collecting tank 81, so that the water is ensured not to overflow from the tank wall of the water collecting tank 81.
