In an embodiment of the air outlet device 100 of the present invention, the air outlet device 100 includes:
the air duct structure 10 is provided with an air inlet 12 and an air outlet 13, and a water diversion structure 14 is formed on the air duct structure 10; and

Specifically, the air duct structure 10 may be a part of a casing component of the whole machine, for example, when the air outlet device 100 is applied to an air processing device, it is a structure formed inside a casing of the whole machine and integrally formed with the casing; but may be a separately provided cylindrical structure, annular structure, semi-annular structure, or the like. The water dispersing structure 30 is disposed on the inner wall surface of the air duct structure 10, and the water dispersing structure 30 may be a rib, a plate-shaped structure, a protrusion structure, or the like. The water dispersing structure 30 may be integrated with the air duct structure 10 or may be separately disposed. The inner wall surface of the air duct structure 10 between the water dispersing structure 30 and the air outlet 13 is formed as a water supply region 11, and the lowest outer edge of the water supply region 11 is formed as the water diversion structure 14. The water diversion structure 14 may be a guide plane (e.g., water diversion section 14 hereinafter) having a height difference of no more than 6mm from the bottom wall of the water supply structure (e.g., water tray 41 hereinafter); the height difference between the lower end of the guide inclined plane and the bottom wall of the water supply structure (such as a water receiving tray 41 in the following text) is not more than 6 mm; it is also possible to provide a guide step surface whose lower end has a height difference of not more than 6mm from the bottom wall of the water supply structure (for example, the drip tray 41 described later), and in which the height difference between two adjacent steps does not exceed 6 mm.
The fan 20 rotates to drive water in the air duct structure 10 to the end of the water dispersing structure 30, that is, the water dispersing end, via the inner wall surface of the air duct, and then water drops are separated from the inner wall surface of the air duct structure 10 and sucked to the middle wind area of the fan 20 under the action of static pressure, and are discretely atomized into fine micro beads by the fan blades of the fan 20 rotating at high speed to be blown out and utilized. At this moment, the heat exchanger is placed at the downwind direction position of the air outlet device 100, the tiny micro-beads which are blown out by the air outlet device 100 and are discretely atomized by the fan blades can be sprayed on the surface of the heat exchanger, and then the micro-beads are gasified and evaporated, so that heat is absorbed, the heat exchange of the heat exchanger is assisted, the heat exchange efficiency and the energy efficiency of the heat exchanger are further improved, and the heat exchange efficiency and the energy efficiency of the air treatment device provided with the air outlet device 100 are improved.
It should be noted that, the air outlet device 100 generally provided can prevent water from entering the inner wall surface of the air duct structure 10, and prevent splashing from causing adverse effects on the motor. The air outlet device 100 of the present invention is provided with the water diversion structure 14 in the air duct structure 10, and through reasonable cooperation with the fan 20, a negative pressure space is formed at the water diversion structure 14 while air outlet is realized, so that water is sucked into the water diversion structure 14, and further water is utilized (for example, the air is blown out from the air outlet 13 to exchange heat with the heat exchanger, thereby improving heat exchange efficiency and energy efficiency of the heat exchanger, and improving heat exchange efficiency and energy efficiency of the air treatment device).
The following description specifically describes the air duct structure 10 as an air duct, the water dispersing structure 30 as a flow blocking rib, and the fan 20 including an axial flow wind wheel as an example:
as shown in fig. 1 to 13, in an embodiment of the air outlet device 100 of the present invention, the air outlet device 100 includes:
the air guide cylinder 10 is provided with an air inlet 12 and an air outlet 13;
the axial flow wind wheel 20, at least part of the axial flow wind wheel 20 is arranged in the air duct 10;
the flow blocking ribs 30 are convexly arranged on the inner wall surface of the air guide cylinder 10, extend along the circumferential direction of the air guide cylinder 10, and define the inner wall surface of the air guide cylinder 10 between the flow blocking ribs 30 and the air outlet 13 as a water supply area 11; and
a water supply structure 40, the water supply structure 40 being disposed adjacent to the air duct 10 and communicating with the water supply area 11 to supply water to the water supply area 11;
the flow blocking ribs 30 include water dispersing ends extending along the rotation direction of the axial flow wind wheel 20, and the water dispersing ends are arranged higher than the horizontal plane where the center of the air duct 10 is located.
Referring to fig. 4 to 6 and fig. 10, specifically, the air duct 10 is a cylindrical structure with two open ends, one open end is an air inlet 12, the other open end is an air outlet 13, an axis of the air duct 10 is horizontally disposed, and the fan 20 is disposed coaxially with the air duct 10. The fan 20 has an air inlet side and an air outlet side which are oppositely arranged, the air inlet side of the fan 20 extends from the air outlet 13 of the air duct 10 and is accommodated in the air duct 10, and the air outlet side of the fan 20 protrudes from the air outlet 13 of the air duct 10. Furthermore, the lowest part of the inner wall surface of the bottom of the air duct 10 is convexly provided with a flow blocking rib 30, and the flow blocking rib 30 extends along the circumferential direction of the air duct 10, that is, one end of the flow blocking rib 30 extends along the rotation direction of the fan 20, and the other end extends along the direction opposite to the rotation direction of the fan 20. At this time, an inner wall surface of the air guide duct 10 between the flow blocking ribs 30 and the air outlet 13 is defined as a water supply region 11, the water supply structure 40 is disposed adjacent to the air guide duct 10 and adjacent to the water supply region 11, and the water supply structure 40 communicates with the water supply region 11 to supply water droplets to the water supply region 11.
Thus, when the fan 20 rotates at a high speed, the airflow flows through the air inlet 12 of the air duct 10 to the air outlet 13 at a high speed, and can be blown to the heat exchanger 200 of the air treatment device 1000. Because the air at the air inlet side of the air inlet 12 is continuously conveyed to the air outlet 13 side of the air duct 10 by the fan, a negative pressure space is formed at the air inlet side of the air inlet 12 relative to the air outlet 13 side, and at the moment, a pressure difference is formed at two sides of the water drops located in the water supply area 11, so that the water drops move from the air outlet 13 side to the air inlet 12 side to form backflow. Further, the water droplets in the water supply area 11 are accelerated by the blade of the fan 20 rotating at a high speed, then rapidly ascend upward along the inner wall surface of the air guide duct 10 and the upstream surface of the flow blocking rib 30, and then fly to the elevation point B (located in the air guide duct 10) by separating from the inner wall surface of the air guide duct 10 and the upstream surface of the flow blocking rib 30 under the action of inertia. Further, water drops at the elevation point B (located in the air duct 10) are sucked toward the fan 20 under the action of static pressure, and are discretely atomized into fine micro-beads by the fan blades of the fan 20 rotating at a high speed and blown toward the high-temperature heat exchanger 200 for gasification and evaporation, so that the heat exchanger 200 is assisted in heat dissipation and cooling, and further, the heat exchanger 200 is cooled by air cooling, and meanwhile, a water cooling function is added, the heat exchange efficiency of the heat exchanger 200 is improved, and the energy efficiency of the air treatment device 1000 with the blowing structure of the present invention is improved.
Of course, it will be appreciated that the flow-blocking ribs 30 may also be joined end to form a loop, resulting in a flow-blocking collar.
Referring to fig. 10 and 11, in an embodiment of the present disclosure, the flow blocking rib 30 includes a main flow guiding section 35 and an auxiliary flow guiding section 37, the main flow guiding section 35 has two opposite sides, one side of the main flow guiding section 35 is connected to an inner wall surface of the air guiding cylinder 10, the other side extends from the air inlet 12 to the air outlet 13, and the auxiliary flow guiding section 37 extends along a radial direction of the air guiding cylinder 10. In this embodiment, one side of the flow blocking rib 30 is connected to the inner wall surface of the air guide duct 10, and the other side of the flow blocking rib extends from the air inlet 12 to the air outlet 13, so that the flow blocking rib has a guiding effect on the flow of air in the air guide duct 10, noise generated by friction between the air entering the air guide duct 10 and the side surface of the air inlet 12 of the air guide duct 10 is reduced, loss of air inlet energy is reduced, and wind resistance is reduced, thereby improving the ability of the fan to blow fine micro-beads, and further improving the heat exchange efficiency of the heat exchanger 200 and the energy efficiency of the air treatment device 1000. Because the air guide cylinder 10 is annularly arranged, the auxiliary flow guide section 37 extends along the radial direction of the air guide cylinder 10, so that the stress of the main flow guide section 35 can be uniformly distributed, and the stability of the flow blocking ribs 30 is improved.
Referring to fig. 12 and 13, in an embodiment of the present application, the water dispersing end of the flow blocking rib 30 extending along the rotation direction of the axial flow wind wheel 20 is higher than the horizontal plane where the center of the air duct 10 is located, so that water droplets can be accelerated to a position higher than the horizontal plane where the center of the air duct 10 is located along the inner wall surface of the air duct 10 and the upstream surface 30a of the flow blocking rib 30, so that the water droplets obtain greater kinetic energy to reach a position higher than the horizontal plane where the center of the air duct 10 is located, and then are discretely atomized by the fan blades, and further sprayed to cover a wider range on the heat exchanger 200, so that the heat exchange efficiency of the heat exchanger 200 is further improved, and the energy efficiency of the heat exchanger 200 and the air treatment device 1000 can be further improved.
In an embodiment of the air outlet device 100 of the present invention, an included angle between a connection line between the water dispersing end and the center of the air guiding duct 10 and a horizontal plane is defined as α, where α is greater than 0 ° and less than or equal to 60 °. Therefore, the included angle alpha between the connecting line of the water dispersing end of the flow blocking rib 30 and the center of the air duct 10 and the horizontal plane can be effectively controlled within the range of not more than 60 degrees, and the phenomenon that water drops are separated from the inner wall surface of the air duct 10 too late due to the fact that the water dispersing end of the flow blocking rib 30 is too high (the included angle alpha is too large) is avoided, so that the range of the heat exchanger 200 covered by spraying after water drops are dispersed and atomized is obviously deviated is avoided, namely the range of the heat exchanger 200 covered by spraying after water drops are dispersed and atomized is obviously reduced, and the better heat exchange efficiency and energy efficiency of the heat exchanger 200 are guaranteed. It is understood that in practical applications, the included angle α may be selected from 1 °, 2 °, 3 °, 5 °, 10 °, 20 °, 40 °, or 60 °.
Furthermore, the included angle alpha between the connecting line of the water dispersing end and the center of the air duct 10 and the horizontal plane is not less than 30 degrees, namely alpha is not less than 30 degrees. Therefore, the included angle alpha between the connecting line of the water dispersing end of the flow blocking rib 30 and the center of the air duct 10 and the horizontal plane can be further controlled within the range of not less than 30 degrees, and the phenomenon that water drops are separated from the inner wall surface of the air duct 10 too early due to too low water dispersing end (the included angle alpha is too small) of the flow blocking rib 30 is avoided, so that the range of the heat exchanger 200 covered by spraying after dispersion atomization of the water drops is obviously deviated downwards is avoided, namely the range of the heat exchanger 200 covered by spraying after dispersion atomization of the water drops is obviously reduced, and the better heat exchange efficiency and energy efficiency of the heat exchanger 200 are ensured. It is understood that in practical applications, the included angle α may be selected from 30 °, 31 °, 32 °, 35 °, 40 °, 50 °, or 60 °.
Referring to fig. 12 and 13, in an embodiment of the air outlet device 100 of the present invention, the flow blocking ribs 30 further include a starting point end extending in a direction opposite to a rotation direction of the axial flow wind wheel 20.
In this way, by means of the arrangement that the starting point end extends along the opposite direction of the rotation direction of the axial flow wind wheel 20, the amount of water drops which can be blocked by the flow blocking ribs 30 can be increased, and the possibility that the water drops overflow to the other side or splash around the flow blocking ribs 30 is reduced, so that more water drops are accelerated to complete the processes of climbing, suction, discrete atomization, spraying coverage, evaporation gasification and the like, namely more water drops are used for heat dissipation of the heat exchanger 200, the heat exchange efficiency of the heat exchanger 200 is further increased, and the energy efficiency of the heat exchanger 200 and the air treatment device 1000 is further increased.
Further, the flow blocking ribs 30 are distributed on the inner wall surface of the air duct 10 in a range of 0 to 45 degrees at most in the opposite direction along the rotation direction of the axial flow wind wheel 20 from the vertical surface where the axis of the air duct 10 is located, that is, an included angle β between a connecting line of the starting point end and the center of the air duct 10 and the vertical surface is not more than 45 degrees, that is, β is not more than 45 degrees. Therefore, the included angle beta between the connecting line of the starting point end of the flow blocking rib 30 and the center of the air duct 10 and the vertical plane can be effectively controlled within the range of not more than 45 degrees, the obvious reduction of air volume caused by the overhigh starting point end of the flow blocking rib 30 (the overlarge included angle beta) and the resource waste and the cost improvement caused by no water drop blocked near the starting point end of the flow blocking rib 30 caused by the overhigh starting point end of the flow blocking rib 30 (the overlarge included angle beta) are avoided. It is understood that in practical applications, the included angle β may be selected from 1 °, 2 °, 3 °, 5 °, 10 °, 20 °, 40 °, or 45 °.
Further, the inner wall surface of the air duct 10 is distributed with the flow blocking ribs 30 at least in the range of 0 to 10 degrees in the opposite direction along the rotation direction of the axial flow wind wheel 20 from the vertical surface where the axis of the air duct 10 is located, that is, the included angle β between the connecting line of the starting point end and the center of the air duct 10 and the vertical surface is not less than 10 degrees, that is, β is not less than 10 degrees. Therefore, the included angle beta between the connecting line of the starting point end of the flow blocking rib 30 and the center of the air duct 10 and the vertical plane can be further controlled to be not less than 10 degrees, so that most of water drops are blocked by the flow blocking rib 30, the possibility that the water drops overflow to the other side or splash around after bypassing the flow blocking rib 30 is further reduced, more water drops are accelerated to finish the processes of climbing, sucking, discrete atomization, spraying coverage, evaporation gasification and the like, namely more water drops are used for heat dissipation of the heat exchanger 200, the heat exchange efficiency of the heat exchanger 200 is further improved, and the energy efficiency of the heat exchanger 200 and the air treatment device 1000 is further improved. It is understood that, in practical applications, the included angle β may be 10 °, 11 °, 12 °, 15 °, 20 °, 40 °, or 45 °.
Referring to fig. 8 and 9, in an embodiment of the present application, a height L of the flow blocking ribs 30 in a radial direction of the air duct 10 is set within a range of L being greater than or equal to 5mm and less than or equal to 17mm, because a maximum diameter of a water droplet that can be formed by the water droplet is 4mm to 5mm under the action of surface tension, when the height of the flow blocking ribs 30 is less than 5mm, the height L of the flow blocking ribs 30 protruding from an inner wall surface of the air duct 10 is lower than the maximum diameter (4mm to 5mm) of the water droplet that can be formed under the action of surface tension, which further causes the water droplet to "climb over" the flow blocking ribs 30 to be lost, and avoids a reduction in heat exchange efficiency of the heat exchanger 200 caused thereby; when the height of the flow blocking ribs 30 is larger than 17mm, the height of the flow blocking ribs 30 is too high, so that wind passing through the air duct 10 is blocked, wind energy is reduced, water drops can not be blown to the heat exchanger 200 by the axial flow wind wheel 20 well, and the production and processing cost is increased by the axial flow wind wheel 20 with too high height, so that the use by a user is inconvenient. When the height L of the flow blocking ribs 30 is set within the range that L is not less than 5mm and not more than 17mm, the height L of the flow blocking ribs 30 protruding from the inner wall surface of the air duct 10 is not less than the maximum diameter (4mm to 5mm) of water drops which can be formed under the action of surface tension, so that the water drops are prevented from "crossing" the flow blocking ribs 30 to be lost, the reduction of the heat exchange efficiency of the heat exchanger 200 caused by the loss is avoided, the reduction of wind energy passing through the air duct 10 is well prevented, the production and processing costs are ensured, the capability of a fan for blowing fine micro-beads is improved, and the heat exchange efficiency of the heat exchanger 200 and the energy efficiency of the air treatment device 1000 are further improved. It can be understood that the height L of the flow blocking rib 30 can be set to be 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm or 16mm, and the like, and the height L of the flow blocking rib 30 protruding from the inner wall surface of the air guide tube 10 can be not less than the maximum diameter (4mm to 5mm) of a water drop which can be formed under the action of surface tension, so as to avoid the water drop from "turning over" the flow blocking rib 30 to cause loss, avoid the reduction of the heat exchange efficiency of the heat exchanger 200 caused by the loss, better prevent the reduction of wind energy passing through the air guide tube 10, ensure the production and processing costs, improve the blowing capability of the fan for small micro-beads, and further improve the heat exchange efficiency of the heat exchanger 200 and the energy efficiency of the air treatment device 1000.
In an embodiment of the present application, a height of the main flow guiding section 35 in a radial direction of the air guiding cylinder 10 is d, a height of the auxiliary flow guiding section 37 in the radial direction of the air guiding cylinder 10 is l, and a value range of a sum of d and l is: d + l is more than or equal to 5mm and less than or equal to 17 mm. The main guide flow section 35 is mainly used for guiding the condensed water in the water tray 41, so that the condensed water can climb along the air guide cylinder 10 and then be blown away by the axial flow wind wheel 20; and the main air guiding section 35 is also used for guiding the air flow flowing into the air guiding duct 10 from the air inlet 12, so as to ensure that the air guiding duct 10 has a better air inlet amount. The auxiliary flow guide section 37 is mainly used for reinforcing the structure of the main flow guide section 35, the main flow guide section 35 extends along the inner wall surface of the air guide cylinder 10, and the end part of the main flow guide section 35, which deviates from the air guide cylinder 10, is a free end, so that the main flow guide section 35 is easily stressed to influence the structural stability, and the auxiliary flow guide section 37 is arranged to be convenient for leaving machining allowance when the main flow guide section 35 is cast and forged, so that the water guide and air guide effects of the flow blocking ribs 30 are prevented from being reduced due to machining errors.
In an embodiment of the present application, the length d is a length from a side edge of the main flow guiding section 35 connected to the inner wall surface of the air guiding duct 10 to a radial direction of the air guiding duct 10 where the main flow guiding section 35 is connected to the auxiliary flow guiding section 37; the length of the connection between the free end of the auxiliary flow guide section 37 and the main flow guide section 35 and the auxiliary flow guide section 37 in the radial direction of the air guide duct 10; setting the value range of the sum of d and l as follows: d + l is more than or equal to 5mm and less than or equal to 17mm, so that water in the water supply structure 40 can better enter the water supply area 11 from the water supply structure 40 under the combined action of liquid surface tension, centrifugal action and siphon effect of the axial flow wind wheel 20 when the water is statically placed, the wind energy passing through the air guide cylinder 10 is better prevented from being reduced, the production and processing cost is ensured, the capability of the fan for blowing fine micro-beads is improved, and the heat exchange efficiency of the heat exchanger 200 and the energy efficiency of the air treatment device 1000 are further improved.
Referring to fig. 9, in an embodiment of the present application, a value range of d is: d is more than or equal to 5mm and less than or equal to 12 mm; because the maximum diameter of the water drop formed by the water drop under the action of surface tension is 4mm to 5mm, when the height of the flow blocking ribs 30 is less than 5mm, the height of the flow blocking ribs 30 protruding from the inner wall surface of the air guide duct 10 is less than the maximum diameter (4mm to 5mm) of water drops which can be formed under the action of surface tension, thereby leading to the loss of water drops when the water drops cross the flow blocking ribs 30, avoiding the reduction of the heat exchange efficiency of the heat exchanger 200 caused by the loss, therefore, the air can not be blown to the heat exchanger 200 by the axial flow wind wheel 20 well, when the height of the main guide flow section 35 is more than 12mm, the height of the main guide flow section 35 is too high, the wind passing through the wind guide duct 10 is blocked, the wind energy is reduced, and the water drops are not well blown to the heat exchanger 200 by the axial flow wind wheel 20, and the axial flow wind wheel 20 with too high height increases the production and processing cost and is inconvenient for users to use. When the height d of the main flow guiding section 35 is set within the range that d is not less than 5mm and not more than 12mm, water in the water supply structure 40 can better enter the water supply area 11 from the water supply structure 40 under the combined action of liquid surface tension, centrifugal action of the axial flow wind wheel 20 and siphon effect when the water is statically placed, and the wind energy passing through the air guide cylinder 10 is better prevented from being reduced, so that the production and processing cost is ensured, the capability of the fan for blowing fine micro-beads is improved, and the heat exchange efficiency of the heat exchanger 200 and the energy efficiency of the air treatment device 1000 are further improved. It can be understood that the height d of the main flow guiding section 35 can be set to be 6mm, 7mm, 8mm, 9mm, 10mm or 11mm, and the like, so that the height H of the flow blocking ribs 30 protruding from the inner wall surface of the air duct 10 is not less than the maximum diameter (4mm to 5mm) of water drops which can be formed under the action of surface tension, thereby avoiding the loss of water drops when the water drops "turn over" the flow blocking ribs 30, avoiding the reduction of the heat exchange efficiency of the heat exchanger 200 caused by the loss, better preventing the reduction of wind energy passing through the air duct 10, ensuring the production and processing costs, improving the blowing capability of the fan on fine micro-beads, and further improving the heat exchange efficiency of the heat exchanger 200 and the energy efficiency of the air treatment device 1000.
In an embodiment of the present application, a value range of l is: l is more than 0mm and less than or equal to 5 mm. Because the auxiliary diversion section 37 has the advantages of increasing the strength of the flow blocking ribs 30 and providing allowance for processing the main diversion section 35, the height of the auxiliary diversion section is set to be larger than 0, but the overhigh auxiliary diversion section 37 can reduce the air inlet amount of the air guide ring and reduce wind energy, further the blowing-off of the axial flow wind wheel 20 to condensed water is reduced, and the efficiency of the heat exchanger 200 is not favorably improved. When the value range of l is as follows: when l is more than 0mm and less than or equal to 5mm, on one hand, the air inlet volume of the air guide cylinder 10 can be ensured, and on the other hand, the strength of the flow blocking ribs 30 can be ensured, so that allowance can be provided for processing the main flow guide section 35. It can be understood that the value of l can also be 1mm, 2mm, 3mm, 4mm, etc., which can ensure the air inlet volume of the air duct 10, ensure the strength of the flow blocking ribs 30 and provide a margin for processing the main flow guide section 35.
Referring to fig. 5 to 9, in an embodiment of the present application, the air inlet 12 includes an air inlet side and an air outlet side, the main diversion section 35 includes a back surface 30b located on the air inlet side, and the back surface 30b is in an arc shape curved toward the air inlet side. The back surface 30b is used for facing the wind, and the back surface 30b is arranged in an arc shape, so that the air flow blown into the air guide duct 10 is guided smoothly, the energy loss of the outlet air is reduced, and the air flow can be guided to deviate to the middle part of the air guide duct 10 under the condition that the energy of the outlet air is not reduced. And the air flow can be smoothly transited, so that the air flow is prevented from impacting on the side surface of the air duct 10, the air flow noise is reduced, and the user experience is improved.
In an embodiment of the present application, a cross section of the backside surface 30b in a radial direction of the air guiding duct 10 forms an arc segment, and a central angle of the arc segment is 30 to 150 degrees. So configured, the airflow is best directed due to the smooth transition of the backing surface 30 b. When the central angle is less than 30 degrees, the air flow flows out of the back surface 30b without transition at the back surface 30b, and the transition effect of the back surface 30b is greatly reduced, so that the energy loss of the air flow is large, and noise is generated; when the central angle is larger than 150 degrees, the air flow is transferred too much to the back surface 30b and flows out of the back surface 30b, and the transfer effect of the back surface 30b is reduced much, so that the energy loss of the air flow is large and noise is generated. When the central angle is 30 degrees to 150 degrees, the transition of the airflow on the back water surface 30b is moderate, the transition of the airflow can be effectively ensured, and the energy loss of the airflow is small. It is understood that the central angle may also be 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, 90 degrees, 100 degrees, 120 degrees, 130 degrees, 140 degrees, etc., which can effectively ensure the transition of the air flow and the energy loss of the air flow is small. And the radius of the arc section can be set according to actual needs, so long as the air flow transition can be effectively ensured, and the energy loss of the air flow is small.
In an embodiment of the present application, the main diversion section 35 includes a back surface 30b located on the air inlet side, and the back surface 30b is bent towards the air inlet side and extends. The back surface 30b is arranged in a shape of Chinese character 'ren', and it can be understood that when the number of the bending sections of the back surface 30b which are bent mutually is small, a larger included angle is formed between the adjacent bending sections; when the number of the bending sections is large, a small included angle is formed between the adjacent bending sections, so that the air flow blown into the air guide duct 10 is guided smoothly, the energy loss of air outlet is reduced, and the air flow can be guided to deviate from the middle part of the air guide duct 10 under the condition that the air outlet energy is not reduced. And the air flow can be smoothly transited, so that the air flow is prevented from impacting on the side surface of the air duct 10, the air flow noise is reduced, and the user experience is improved.
Referring to fig. 8, in an embodiment of the present application, the flow blocking rib 30 further includes an upstream surface 30a away from the backside surface 30b, the upstream surface 30a is provided with a diversion trench 31, and the diversion trench 31 extends along an extending direction of the flow blocking rib 30. The upstream surface 30a is provided to facilitate rapid ascent of water droplets from the water supply structure 40 in the rotation direction of the wind wheel, and the guide grooves 31 are provided to provide a movement track for water supplied from the water supply structure 40 from the water supply region 11, thereby guiding the water to a position suitable for flying.
In an embodiment of the present invention, the back surface 30b is smoothly connected to an outer side surface of the air guiding duct 10. Due to the fact that air flow is prone to generate squeal in a fine gap, the transition surface (the back surface 30b and the outer side surface of the air guide cylinder 10) is in smooth transition, so that air transition is smooth, energy loss of the air flow entering the air guide cylinder 10 is reduced, and noise can be effectively reduced. It will be appreciated that to improve smoothness, the cambered surface may be formed by grinding in with a grinder or die casting with a die casting machine.
Referring to fig. 9, in an embodiment of the present application, the auxiliary flow guiding section 37 extends along a radial direction of the air guiding barrel 10 to form a radial plane, a maximum width of the main flow guiding section 35 from the radial plane in an axial direction of the air guiding ring is w, and a value range of the maximum width w is: w is more than or equal to 3mm and less than or equal to 8 mm. The maximum width is the distance between the highest point of the main flow guide section 35 and a radial plane formed by the auxiliary flow guide section 37 along the axial direction of the air guide ring, when the maximum width w is greater than 8mm, the main flow guide section 35 is raised too high, and the windward angle of the main flow guide section 35 when air flow enters the air guide cylinder 10 is further too large, so that noise is generated; when the maximum width w is less than 3mm, the arc surface of the main air guiding section 35 when the air flow enters the air duct 10 is too small to facilitate air guiding, and when the maximum width w takes a value range as follows: when w is not less than 3mm and not more than 8mm, on one hand, the noise is larger when the airflow enters the air duct 10, and on the other hand, the air duct is facilitated, so that the condensed water is blown away conveniently, and the heat exchange efficiency of the heat exchanger 200 is improved. It can be understood that the maximum width w may also be 4mm, 5mm, 6mm or 7mm, which can prevent the air flow from making a loud noise when entering the air duct 10 and is beneficial to guiding the air.
Referring to fig. 8 of patent 2, in an embodiment of the present application, a distance s from the back surface 30b to the upstream surface 30a is: s is more than or equal to 2mm and less than or equal to 5 mm. This surface of a backing 30b is the thickness of fender stream rib 30 promptly with the distance of upstream surface 30a, when the thickness of fender stream rib 30 is less than 2mm, fender stream rib 30 can produce the swing when the fan is rotatory, thereby be unfavorable for carrying out the water conservancy diversion to the air, when the thickness of fender stream rib 30 is greater than 5mm, can make the forging cost of fender stream rib 30 improve, thereby be unfavorable for the surface of a backing 30b with fender stream rib 30 crooked, when the thickness of fender stream rib 30 is 2mm to 5mm, be convenient for on the one hand its air and water guide, on the other hand easily reduces the forging cost. It can be understood that the thickness of the flow blocking ribs 30 can also be 2.5mm, 3mm, 3.5mm, 4mm or 4.5mm, which is convenient for guiding air and water and can reduce the forging cost.
In an embodiment of the present application, the flow blocking rib 30 is integrally formed with or detachably connected to the air duct 10; and/or, the auxiliary flow guiding section 37 and the flow blocking rib 30 are integrally formed or detachably connected.
The integrally formed arrangement makes the flow blocking ribs 30 and the air duct 10 have no connection gap, so as to best reduce the energy loss of the outlet air and guide the air flow to deviate to the middle of the air duct 10 under the condition that the energy of the outlet air is not reduced. Specifically, in the process of producing the air guide cylinder 10, a section of malleable part is reserved on the outer side surface of the air guide cylinder 10, and then the forged part is bent to make the part have a certain radian. And, the removable connection arrangement facilitates replacement of damaged baffle ribs 30, maintaining the energy efficiency of air treatment device 200.
As shown in fig. 1 to 5, in an embodiment of the air outlet device of the present invention, a water ring 60 is disposed around an outer edge of the air outlet side, and a bottom of the water ring 60 extends into the water pan.
Specifically, the water ring 60 is substantially in a circular ring structure, the air outlet side of the axial flow wind wheel 20 is located at a hollow position in the middle of the water ring 60, and the inner edge of the water ring 60 is arranged around the air outlet side of the axial flow wind wheel 20 and is fixedly connected with each blade of the axial flow wind wheel 20, so that the water ring 60 and the axial flow wind wheel 20 are coaxially arranged. At this time, the water ring 60 is vertically arranged, and the lowest position of the inner edge of the bottom of the water ring is not higher than the side wall of the water receiving tray.
Thus, when the water ring 60 rotates along with the axial flow wind wheel 20, the inner edge of the bottom of the water ring 60 takes up the water in the water pan, and the water is blown to the heat exchanger 200 by the axial flow wind wheel 20, so as to further perform water cooling on the heat exchanger 200, thereby improving the heat exchange efficiency and energy efficiency of the heat exchanger 200.
As shown in fig. 1 to 3, in an embodiment of the air outlet device of the present invention, a distance between the water ring 60 and the air outlet 13 is defined as E, and E is greater than or equal to 10mm and less than or equal to 20 mm. Therefore, on one hand, the distance E between the water ring 60 and the air outlet 13 is controlled to be not less than 10mm, so that the safety distance between the water ring 60 and the air duct 10 can be guaranteed, and the possibility that the water ring 60 collides or extrudes with the air duct 10 due to the fact that the clearance matched with the structure displaces along the axial direction of the air duct 10 when the water ring 60 and the axial flow wind wheel 20 run together is reduced. That is, if the distance E between the water ring 60 and the air outlet 13 is less than 10mm, the probability that the water ring 60 collides or extrudes with the air duct 10 due to the axial displacement of the air duct 10 along the clearance of the structural fit when the water ring and the axial flow wind wheel 20 are operated together will be greatly increased, thereby affecting the operation of the axial flow wind wheel 20 and the water ring 60 and destroying the stability and reliability of the air outlet device 100. On the other hand, the distance E between the water ring 60 and the air outlet 13 is controlled not to exceed 20mm, so that the water carried by the water ring 60 can be ensured to obtain larger wind force to blow to the heat exchanger 200, the part of water energy can cover a wider range on the heat exchanger 200, and the heat exchange efficiency and the energy efficiency of the heat exchanger 200 are improved. It is understood that, in practical application, the distance E between the water ring 60 and the air outlet 13 may be 10mm, 11mm, 12mm, 13mm, 15mm, 18mm, 19mm or 20mm, etc.
As shown in fig. 1 to 3, 14 and 15, in an embodiment of the present invention, the water supply structure 40 includes a water pan 41, and the water pan 41 is horizontally disposed to contain the condensed water. The air duct 10 is arranged in the water receiving tray 41, and the height of at least part of the water supply area 11 is not higher than the height of the side wall of the water receiving tray 41. Thus, when the axial flow wind wheel 20 rotates at a high speed, the condensed water in the water receiving tray 41 will "climb" the water supply area 11 on the inner wall surface of the wind guide ring due to the surface tension of the liquid, the centrifugal action and the siphon effect of the axial flow wind wheel 20. In this way, the secondary use of the condensed water in the air treatment device 1000 (for example, the condensed water generated in the indoor heat exchanger 200 in the cooling state) is also realized. In addition, the temperature of the condensed water is lower, the cooling capacity is more sufficient, and the heat exchange efficiency of the heat exchanger 200 can be higher by performing water cooling on the heat exchanger 200, so that the heat exchange efficiency of the heat exchanger 200 is further improved, and the energy efficiency of the air treatment device 1000 is improved. Further, the inner wall surface of the air duct 10 forms a water diversion section 14 at the position, adjacent to the water pan, of the water supply area 11, and the height difference between the lowest position of the water diversion section 14 and the bottom wall of the water pan is not more than 6 mm.
In this embodiment, the heat exchanger 200 of the air processing apparatus 1000 is disposed on the water pan, and the condensed water generated by the heat exchanger 200 during the operation process directly flows into the water pan, so as to avoid providing a water source in the air outlet apparatus 100. Of course, a piping structure may be used to collect the condensed water and then lead the water source to the water-diverting section 14. Alternatively, a water tank may be provided at the water receiving tray, and water in the water tank flows into the water receiving tray to supply water to the water supply region 11. Of course, in other embodiments, the water supply structure 40 may be a pipeline structure, and directly introduce water drops to the water supply area 11.
Because water is under the effect of surface tension, the maximum diameter of the water droplet that it can form is 4mm to 5mm, for the convenience of less water on the water collector can climb to the water supply area 11 of guide duct, the difference in height of the diapire that sets up drainage section 14 in this embodiment apart from the water collector is no longer than 6mm, and this difference in height can select for use 1mm, 2mm, 3mm, 4mm, 5mm or 6mm in practical application. Meanwhile, the height difference between the highest position of the water diversion section 14 and the bottom wall of the water receiving tray can be set to be not more than 6mm so as to increase the water diversion width of the water diversion section 14, and more water can climb to the water supply area 11 of the air guide cylinder 10 when less water exists in the water receiving tray. In practice, the water diversion section 14 may be arranged as a straight line or an arc.
Further, as shown in fig. 2 to 4, a water collecting groove 411 is formed in a recessed manner on a bottom wall of the water receiving tray 41 on the air outlet side of the air outlet 13, and the water collecting groove 411 is disposed adjacent to the water guiding section 14. The water collection tank 411 is used to collect condensed water. Thereby facilitating the water supply to the water supply area 11 by the axial flow wind wheel 20.
Referring to fig. 14 and 15, in another embodiment of the present invention, in order to facilitate the water in the drip tray 41 to "climb" to the water supply area 11, the outer edge of the water supply area 11 is formed with a water receiving part 15 toward the water collecting sump 411. The water receiving portion 15 is disposed adjacent to the water diversion section 14, and extends toward the direction away from the air guide duct 10 and into the water collection tank 411. The water receiving part 15 can be a sunken step structure, and the height difference between two adjacent step surfaces is not more than 6 mm. In this embodiment, the water receiving portion 15 is provided to drain water in the water collecting tank 411. So that when less water is in the water collecting tank 411, the water climbs to the water receiving part 15 under the negative pressure formed by the axial flow wind wheel 20 and then enters the water supply area 11 from the water guide section, and water supply to the water supply area 11 is realized.
Of course, in other embodiments, the water receiving portion 15 may also be a drainage surface, and the drainage surface may be a plane, an inclined surface, an arc surface, or a stepped surface with a height difference between adjacent steps not exceeding 6 mm. At this time, the upper surface of the water receiving part 15 is connected to the water guide section so that water smoothly enters the water supply area 11.
It can be understood that, in practical application, the drainage surface may be set as a plane, an inclined surface, an arc surface, or a stepped surface with a height difference between adjacent steps not exceeding 6mm, or may be set as a scheme of first plane and then inclined surface, or a scheme of first plane and then arc surface, or a scheme of first stepped surface and then plane, or a scheme of multiple stepped surfaces, and this scheme may be applied to a situation where the depth of the water collection tank 411 is deep.
In order to facilitate the condensed water to climb to the water guiding section 14 when the water amount in the water receiving tray is small, in an embodiment of the present application, the water supplying area 11 of the air guiding duct 10 is provided with a hydrophilic layer (not shown). Because the hydrophilic layer has hydrophilic groups, the hydrophilic layer can generate an adsorption force on water so as to facilitate the water to climb to the water diversion section 14. In this embodiment, the material of the hydrophilic layer may be polyurethane or polyacrylic acid. Polyurethane or polypropylene may be applied to the water-diverting section 14, and the thickness of the coating is 0.01mm to 0.03 mm. In practical use, the hydrophilic layer may also be made of other materials such as fiber.
Referring to fig. 1 to 3 and fig. 14, in order to facilitate the dropping of the condensed water, in the present embodiment, a water falling region 16 is further formed on an inner wall surface of the air guide duct 10, the water supply region 11 and the water falling region 16 are connected to each other along a circumferential direction of the air guide duct 10, and the water falling region 16 is disposed to be inclined toward the air inlet 12. That is, the inner wall surface of the air duct 10 where the water falling area 16 is located extends along the direction from the air inlet 12 to the air outlet 13 and towards the direction close to the central line of the axial flow wind wheel 20, so that when the condensed water moves towards the direction of the air inlet 12, the centrifugal action of the axial flow wind wheel 20 is smaller, and further when the condensed water drips from the air inlet 12, the speed of the horizontal direction is smaller, the distance from the axial flow wind wheel 20 is closer when the condensed water drips, the condensed water can be sucked towards the axial flow wind wheel 20 more quickly under the action of negative pressure, and the auxiliary heat exchanger 200 is convenient to cool.
Referring to fig. 6 to 9, in an embodiment of the present application, on a longitudinal cross section of the air outlet device 100, an included angle between a straight line formed by the water falling region 16 and a center line of the air guiding duct 10 is δ, where δ is greater than or equal to 2 ° and less than or equal to 3 °. In this embodiment, the downpipe region 16 is provided in the form of a partial truncated cone side to facilitate the manufacture of the air guide duct 10. Meanwhile, the air duct 10 in this embodiment may adopt an injection molding or punch forming process, and the angle is set, which is also convenient for forming and demolding of the air duct 10. In other embodiments of the present application, the water falling area 16 may also be in the shape of a cambered surface
As shown in fig. 8 and 9, in an embodiment of the present application, on a longitudinal section of the air outlet device 100, an included angle between a straight line formed by the water supply region 11 and a center line of the air guiding duct 10 is γ, that is, an inclination angle of the water supply region 11 on the longitudinal section is γ, and γ is not less than 2 ° and not more than 3 °. In the embodiment, the air duct 10 is an integrally formed structure, so that the integrally formed structure is convenient, and the height difference of the joint of the water falling area 16 and the water supply area 11 is also reduced, wherein in the embodiment, gamma is selected to be more than or equal to 2 degrees and less than or equal to 3 degrees. In other embodiments of the present invention, δ may also be selected from an angle of 4 °, 5 °, or 6 °, and γ may also be selected from an angle of 4 °, 5 °, or 6 °.
Further, there is a slope or camber transition between the water supply region 11 and the water fall region 16. To reduce the drop at the junction of the water supply region 11 and the water drop region 16 while avoiding stress concentrations at the junction or condensate retention at the junction.
As shown in fig. 8 to 11, in an embodiment of the air outlet device 100 of the present invention, the flow blocking ribs 30 include an upstream surface 30a and a downstream surface 30b that are oppositely disposed, the upstream surface 30a is provided with a diversion trench 31, and the diversion trench 31 extends along an extending direction of the flow blocking ribs 30.
At this moment, the diversion trench 31 can be used for accommodating water drops, provide guide and motion track for the water drops along the climbing of the inner wall surface of the air duct 10, thereby making the climbing process of the water drops more stable, make the system high point B after the water drops fly up more easily controlled, the position is more accurate, and then make the water drops be better to the discrete atomization of water drops by being inhaled the position to the fan blade, obtain more tiny microballon, in order to further accelerate its and heat exchanger 200's heat transfer process, promote heat exchanger 200's heat exchange efficiency, promote air treatment plant 1000's efficiency. Meanwhile, the position of the height-making point B after the water drops fly is more accurate, and the accuracy of the position of the water drops sucked into the fan blades can be improved, so that the dispersion range of the water drops on the heat exchanger 200 after the water drops are dispersed and atomized is wider and more reasonable, more efficient heat exchange is realized, and the energy efficiency is improved.
As shown in fig. 1 to 11, in an embodiment of the air outlet device 100 of the present invention, one end of the guiding groove 31 extending along the rotation direction of the axial flow wind wheel 20 penetrates through an end surface of the flow blocking rib 30. So, can make the water droplet deviate from in guiding gutter 31 smoothly and fly upward to system high point B, reduce the resistance that receives when the water droplet deviates from in guiding gutter 31, make the kinetic energy after the water droplet deviates from in guiding gutter 31 bigger, can come to higher position to after being dispersed atomizing by axial fan 20's fan blade, can be on heat exchanger 200 more extensive dispersion, thereby realize more efficient heat transfer, promote the efficiency.
As shown in fig. 1 to fig. 11, in an embodiment of the air outlet device 100 of the present invention, the cross section of the guiding groove 31 is at least partially arc-shaped.
In this embodiment, the cross section of the guiding groove 31 is formed by two parts, i.e., a straight part provided by the inner wall surface of the air guiding duct 10 and an arc part provided by the upstream surface 30a of the flow blocking rib 30. That is, the upstream surface 30a of the flow blocking rib 30 is curved. Of course, in other embodiments, the cross section of the diversion trench 31 may be all arc-shaped. It should be noted that the cross section is a plane perpendicular to the extending direction of the flow blocking ribs 30.
So, when the water droplet is acceptd in guiding gutter 31, can laminate more with the cell wall of guiding gutter 31, make the water droplet more stable when climbing along the internal face of guide duct 10 in guiding gutter 31, avoid the water droplet to make a round trip to rock and cause and fly upward the route skew, thereby make system high point B after the water droplet flies upward more easily control, the position is more accurate, and then it is better to the discrete atomization of water droplet to make the water droplet be inhaled the position of fan blade, obtain more tiny microballon, in order to further accelerate its and heat exchanger 200's heat transfer process, promote heat exchange efficiency of heat exchanger 200, promote air treatment plant 1000's efficiency. Meanwhile, the position of the height-making point B after the water drops fly is more accurate, and the accuracy of the position of the water drops sucked into the fan blades can be improved, so that the dispersion range of the water drops on the heat exchanger 200 after the water drops are dispersed and atomized is wider and more reasonable, more efficient heat exchange is realized, and the energy efficiency is improved. And, avoid the water droplet to shake still can make the kinetic energy loss of water droplet in the climbing in-process reduce, improved the kinetic energy when the water droplet flies upward, make the system high point B's of water droplet position higher to make it can cover wider scope on heat exchanger 200 after being dispersed atomizing by the fan blade, promote heat exchange efficiency and efficiency.
Further, the width of the guiding groove 31 along the radial direction of the air duct 10 is defined as d, and d is greater than or equal to 5 mm. Therefore, the width d of the diversion trench 31 along the radial direction of the air duct 10 can be effectively controlled within the range of not less than 5mm, so that the width d of the diversion trench 31 along the radial direction of the air duct 10 is not less than the maximum diameter (4mm to 5mm) of water drops which can be formed under the action of surface tension, and the water drops can enter the diversion trench 31 to move along the diversion trench 31 more smoothly.
Further, the width d of the guiding groove 31 along the radial direction of the air duct 10 is not more than 10mm, that is, d is not more than 10 mm. So, can further control guiding gutter 31 along radial width d of guide duct 10 within the scope that is not more than 10mm, thereby avoid guiding gutter 31 along radial width d of guide duct 10 too wide and lead to the water droplet to take place to rock back and forth when moving along guiding gutter 31, make the kinetic energy loss of water droplet in the climbing process further reduce, kinetic energy when having further improved the water droplet and having flown upward promptly, make the system height point B's of water droplet position higher, thereby make it can cover the wider scope on heat exchanger 200 after being dispersed atomizing by the fan blade, promote heat exchange efficiency and energy efficiency.
It will be appreciated that the width d may be selected to be 5mm, 5.5mm, 6mm, 7mm, 8mm, 9mm or 10mm in practice.
As shown in fig. 1 to fig. 3 and fig. 14, in an embodiment of the air outlet device 100 of the present invention, the axial flow wind wheel 20 includes an air inlet side and an air outlet side that are oppositely disposed, and the air inlet side extends into the air outlet 13. That is, the air inlet side of the axial flow wind wheel 20 extends from the air outlet 13 of the air duct 10 and is accommodated in the air duct 10. Therefore, on one hand, a matching structure between the inner wall surface of the air duct 10 and the blades of the axial flow wind wheel 20 is formed, so that the blades can cut air, the air volume of the air outlet device 100 is effectively increased, the air outlet of the air outlet device 100 is more concentrated, the heat exchanger 200 can exchange heat better, and the heat exchange efficiency of the heat exchanger 200 is improved; on the other hand, the blades of the axial flow wind wheel 20 can more easily bear the water drops moving towards the axial flow wind wheel 20 under the action of static pressure, so that the discrete atomization of the water drops by the blades is better, finer micro beads are obtained, the heat exchange process between the blades and the heat exchanger 200 is further accelerated, the heat exchange efficiency of the heat exchanger 200 is improved, and the energy efficiency of the air treatment device 1000 is improved.
As shown in fig. 1 to 3 and fig. 14, in an embodiment of the air outlet device 100 of the present invention, the air outlet side protrudes from the air outlet 13. That is, the side of the axial flow wind wheel 20 departing from the air inlet side thereof protrudes out of the air outlet 13 of the air duct 10. Therefore, on one hand, the micro-beads obtained after water drops are discretely atomized by the fan blades can be effectively prevented from being intercepted by the inner wall surface of the air guide cylinder 10, more micro-beads can be sprayed to the heat exchanger 200, and the heat exchange efficiency and the energy efficiency of the heat exchanger 200 are improved; on the other hand, the noise of the air outlet device 100 can be effectively reduced.
As shown in fig. 1 to fig. 15, in an embodiment of the air outlet device 100 of the present invention, the flow blocking ribs 30 are disposed adjacent to the air inlet 12, and the axial flow wind wheel 20 is located on a side of the flow blocking ring facing the air outlet 13. That is, the air inlet side of the axial flow wind wheel 20 extends into the air duct 10 from the air outlet 13 of the air duct 10, and is spaced from the flow blocking ribs 30 in the axial direction of the air duct 10. Therefore, the overlapping of the flow blocking ribs 30 and the axial flow wind wheel 20 in the radial direction of the air duct 10 is effectively avoided, the outer edge of the fan blade of the axial flow wind wheel 20 is closer to the inner wall surface of the air duct 10, the air volume of the air outlet device 100 is effectively increased, the heat exchanger 200 can exchange heat better, and the heat exchange efficiency of the heat exchanger 200 is improved.
As shown in fig. 3 to 14, in an embodiment of the air outlet device 100 of the present invention, a distance D between the flow blocking ribs 30 and the axial flow wind wheel 20 is defined, and D is less than or equal to 20 mm. Therefore, the situation that the height of water drops at the elevation point B (located in the air duct 10) is too low and the water drops are too close to the center of the axial flow wind wheel 20 when the water drops are sucked to the axial flow wind wheel 20 under the action of static pressure can be effectively avoided, and the situation that the water drops are too poor in discrete atomization and too small in range of being sprayed to the heat exchanger 200 caused by the over-poor discrete atomization is avoided. That is, if the distance D between the flow blocking ribs 30 and the axial flow wind wheel 20 exceeds 20mm, the height of the water drops at the height point B (located in the air duct 10) is too low when the water drops are sucked to the axial flow wind wheel 20 under the action of static pressure, and the water drops are too close to the center of the axial flow wind wheel 20, so that the water drops are dispersed and atomized too poorly and sprayed to the heat exchanger 200 too small, and the heat exchange efficiency and the energy efficiency of the heat exchanger 200 are not favorably and effectively improved. It is understood that the distance D of the flow blocking ribs 30 from the axial flow wind wheel 20 may be 10mm, 11mm, 12mm, 15mm, 20mm, etc.
As shown in FIG. 3 to FIG. 14, in an embodiment of the air outlet device 100 of the present invention, the distance between the flow blocking ribs 30 and the axial flow wind wheel 20 is defined as D, and D ≧ 6 mm. Therefore, the possibility that the axial flow wind wheel 20 collides or extrudes with the flow blocking ribs 30 due to the axial displacement of the structure-matched gap along the air duct 10 in the operation process can be effectively reduced, and the safety distance between the flow blocking ribs 30 and the axial flow wind wheel 20 is ensured. That is, if the distance D between the flow blocking ribs 30 and the axial flow wind wheel 20 is less than 6mm, the probability that the axial flow wind wheel 20 is displaced along the axial direction of the air duct 10 and collides or extrudes with the flow blocking ribs 30 due to the clearance of structural fit in the operation process is greatly increased, thereby affecting the operation of the axial flow wind wheel 20 and destroying the stability and reliability of the air outlet device 100. It is understood that the distance D of the flow blocking ribs 30 from the axial flow wind wheel 20 may be 6mm, 7mm, 8mm, 9mm, or 10mm, etc.
As shown in fig. 3 to 14, in an embodiment of the air outlet device 100 of the present invention, the water supply structure 40 includes a water pan 41, the air duct 10 is disposed in the water pan 41, and a height of at least a portion of the water supply area 11 is not higher than a height of a sidewall of the water pan 41. Therefore, the water supply structure 40 is effectively simplified, the structure is simple, the production and the manufacture are convenient, the assembly is convenient, other parts are not introduced too much, and the cost is lower. Meanwhile, the method has higher stability and reliability.
Further, the height difference h between the lowest position of the water supply area 11 and the bottom wall of the water tray 41 is not more than 6 mm. In this embodiment, the water pan 41 is horizontally disposed and used for containing condensed water. The air duct 10 is arranged in the water receiving tray 41, and the height of at least part of the water supply area 11 is not higher than the height of the side wall of the water receiving tray 41. Thus, when the axial flow wind wheel 20 rotates at a high speed, the condensed water in the water receiving tray 41 will "climb" the water supply area 11 on the inner surface of the wind guide ring due to the surface tension of the liquid, the centrifugal effect and the siphon effect of the axial flow wind wheel 20. Because the maximum diameter of water drops formed by water under the action of surface tension is 4mm to 5mm, in order to facilitate that less water in the water receiving tray 41 can climb to the water supply area 11 of the air guide ring under the centrifugal action of the axial flow wind wheel 20, the height difference h between the lowest part of the inner wall surface of the air guide cylinder 10 and the bottom wall of the water receiving tray 41 is not more than 6mm, and the height difference can be 1mm, 2mm, 3mm, 4mm, 5mm or 6mm in practical application.
