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
the fan 20 is arranged corresponding to the air duct structure 10, the fan 20 introduces air flow from the air inlet 12, blows the air flow from the air outlet 13, and forms a negative pressure space at the water diversion structure 14 to suck water into the water diversion structure 14.
Further, the air outlet device 100 further includes a water dispersing structure 30, and the water dispersing structure 30 is disposed on an inner wall surface of the air duct structure 10; the fan 20 blows water out through the air outlet 13 at the water-dispersing end of the water-dispersing structure 30.
Specifically, the air duct structure 10 may be a part of a housing member of the complete machine, for example, when the air outlet device 100 is applied to an air treatment device, it is a structure formed inside a housing of the complete machine and integrally formed with the housing; it may be a cylindrical structure, a ring structure, a semi-annular structure, or the like, which are separately provided. 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 ribs, plate-like structures, protruding structures, or the like. The water dispersing structure 30 can be integrated with the air duct structure 10 or can be arranged separately. The inner wall surface of the air duct structure 10 between the water scattering structure 30 and the air outlet 13 forms a water supply area 11, and the outer edge of the lowest part of the water supply area 11 is formed as the water diversion structure 14. The water directing structure 14 may be a guide plane having a height difference of not more than 6mm from the bottom wall of the water supplying structure (e.g., a water receiving tray 41 hereinafter); or may be a guide slope whose lower end is not more than 6mm in height from the bottom wall of the water supply structure (for example, a water receiving tray 41 hereinafter); it may also be a guide step surface whose lower end is not more than 6mm in height from the bottom wall of the water supply structure (for example, a water receiving tray 41 to be described later), and whose adjacent steps are not more than 6mm in height.
The fan 20 rotates to drive water in the air duct structure 10 to the end part of the water dispersing structure 30, namely the water dispersing end, through the inner wall surface of the air duct, then water drops are separated from the inner wall surface of the air duct structure 10 and are sucked to the middle wind area of the fan 20 under the action of static pressure, and fine microbeads are discretely atomized by the fan blades through the fan blades of the fan 20 rotating at a high speed to be blown out and utilized. At this time, the heat exchanger is placed at the downwind position of the air outlet device 100, and the tiny microbeads which are discretely atomized into by the fan blades and blown out by the air outlet device 100 are sprayed on the surface of the heat exchanger, and then 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 will prevent water from entering the inner wall surface of the air duct structure 10, and avoid the adverse effect of splashing on the motor. The air outlet device 100 of the present invention, by arranging the water diversion structure 14 on the air duct structure 10 and by reasonably matching with the fan 20, can form a negative pressure space at the water diversion structure 14 while realizing air outlet, thereby sucking water into the water diversion structure 14 and further utilizing the water (for example, blowing out from the air outlet 13 to exchange heat of a heat exchanger, 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 specifically describes an example in which the air duct structure 10 is an air duct and the water dispersing structure 30 is a flow blocking ring:
as shown in fig. 1 to 5, in an embodiment of an air outlet device 100 of the present invention, the air outlet device 100 includes:
the air duct 10, the said air duct 10 has air inlet 12 and air outlet 13;
an axial flow wind wheel 20, wherein the axial flow wind wheel 20 is at least partially arranged in the air duct 10;
a flow blocking ring 30, wherein the flow blocking ring 30 is convexly arranged on the inner wall surface of the air duct 10, and is circumferentially arranged along the circumferential direction of the air duct 10, and the inner wall surface of the air duct 10 between the flow blocking ring 30 and the air outlet 13 is provided with a water supply area 11; and
and a water supply structure 40, wherein the water supply structure 40 is arranged adjacent to the air duct 10 and is communicated with the water supply area 11 to supply water to the water supply area 11.
At this time, the fan 20 blows air from the air inlet 12 to the air outlet 13, and forms a negative pressure space on the air inlet side of the air inlet 12 to suck water into the water supply area 11, and the water in the water supply area 11 is blown out through the air outlet 12.
Specifically, the air duct 10 has a cylindrical structure with two open ends, one open end of the air duct is an air inlet 12, the other open end of the air duct is an air outlet 13, the axis of the air duct 10 is horizontally arranged, and the axial flow wind wheel 20 and the air duct 10 are coaxially arranged. The axial flow wind wheel 20 is provided with an air inlet side and an air outlet side which are oppositely arranged, 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 accommodated in the air duct 10, and the air outlet side of the axial flow wind wheel 20 protrudes out of the air outlet 13 of the air duct 10. The flow blocking ring 30 is substantially circular, and may be obtained by hollowing out a circular plate. Further, the flow blocking ring 30 is convexly arranged on the inner wall surface of the air duct 10 and is coaxially arranged with the air duct 10, and the flow blocking ring 30 is provided with an upstream surface and a downstream surface which are oppositely arranged. At this time, an inner wall surface of the air duct 10 between the flow blocking ring 30 and the air outlet 13 is defined as a water supply area 11, the water supply structure 40 is disposed adjacent to the air duct 10 and adjacent to the water supply area 11, and the water supply structure 40 communicates with the water supply area 11 to supply water droplets to the water supply area 11.
Thus, when the fan 20 (axial flow wind wheel 20) rotates at a high speed, the air flow will flow at a high speed through the air inlet 12 of the air duct 10 to the air outlet 13, and can be blown to the heat exchanger 200 of the air treatment device 1000. Because the air on 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 20 (the axial flow wind wheel 20), a negative pressure space is formed on the air inlet side of the air inlet 12 opposite to the air outlet 13 side, at the moment, a pressure difference is formed on two sides of water drops in the water supply area 11, and the water drops move from the air outlet 13 side to the air inlet 12 side to form backflow. Further, the water drops in the water supply area 11 are accelerated by the fan blades of the fan 20 (the axial flow wind wheel 20) rotating at high speed, then quickly climb upwards along the inner wall surface of the air duct 10 and along the upstream surface of the flow blocking rib 30, and then separate from the inner wall surface of the air duct 10 and the upstream surface of the flow blocking rib 30 under the action of inertia to fly to the high point B (located in the air duct 10). Further, the water drop at the high point B (located in the air duct 10) is sucked to the fan 20 (the axial flow wind wheel 20) under the action of static pressure, and is discretely atomized into fine micro beads by the fan blades of the fan 20 (the axial flow wind wheel 20) rotating at high speed to be blown to the high-temperature heat exchanger 200 for gasification and evaporation, so that the heat exchanger 200 is assisted in heat dissipation and cooling, and the air cooling and cooling of the heat exchanger 200 are performed, meanwhile, the water cooling function is increased, 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 is improved.
In this embodiment, the water supply structure 40 includes a water receiving tray, which is horizontally disposed for receiving condensed water. The air duct 10 is arranged in the water receiving disc, and at least part of the water supply area 11 is not higher than the side wall of the water receiving disc. Thus, when the axial flow wind wheel 20 rotates at a high speed, the condensed water in the water receiving disc can "climb" the water supply area 11 on the inner surface of the wind guiding ring due to the action of the surface tension of the liquid, the centrifugal action and the siphon effect of the axial flow wind wheel 20. In this way, the air treatment device 1000 can be reused for condensed water (for example, condensed water generated in the cooling state of the indoor heat exchanger 200). And, the temperature of comdenstion water is lower, the cold volume is more sufficient for carrying out "water cooling" to heat exchanger 200 can make the heat exchange efficiency of heat exchanger 200 higher, thereby further promote the heat exchange efficiency of heat exchanger 200, promote the energy efficiency of air treatment device 1000.
Of course, in other embodiments, the water supply structure 40 may be a pipe structure, which directly directs water droplets to the water supply area 11.
In an embodiment of the air outlet device of the present invention, as shown in fig. 1 to 5, the height of the baffle ring 30 protruding from the inner wall surface of the air duct 10 is defined as H, and H is 5mm or less and 15mm or less. In this way, on the one hand, the height H of the baffle ring 30 protruding from the inner wall surface of the air duct 10 can be effectively controlled within a range of not less than 5mm, so that the height H of the baffle ring 30 protruding from the inner wall surface of the air duct 10 is not less than the maximum diameter (4 mm to 5 mm) of water drops which can be formed under the action of surface tension, and further, the water drops are prevented from "crossing over" the baffle ring 30 to be lost, and the heat exchange efficiency of the heat exchanger 200 is prevented from being reduced; on the other hand, the height H of the baffle ring 30 protruding from the inner wall surface of the air duct 10 can be further controlled within a range not exceeding 15mm, so as to avoid the decrease of the air volume of the air outlet device 100 caused by the too high height H of the baffle ring 30 protruding from the inner wall surface of the air duct 10, and avoid the decrease of the heat exchange efficiency of the heat exchanger 200 caused by the too high height H. It will be appreciated that in practical applications, the height H of the baffle ring 30 protruding from the inner wall surface of the air duct 10 may be 5mm, 6mm, 7mm, 8mm, 10mm or 15mm.
As shown in fig. 1 to 5, in an embodiment of the air outlet device of the present invention, the flow blocking ring 30 is disposed adjacent to the air inlet 12, and the axial flow wind wheel 20 is located on a side of the flow blocking ring 30 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 arranged at intervals with the flow blocking ring 30 in the axial direction of the air duct 10. Therefore, the radial overlapping of the flow blocking ring 30 and the axial flow wind wheel 20 on the air duct 10 is effectively avoided, even if the flow blocking ring 30 and the axial flow wind wheel 20 are arranged at intervals in the axial direction of the air duct 10, the outer edges of the blades of the axial flow wind wheel 20 are closer to the inner wall surface of the air duct 10, the air quantity of the air outlet device 100 is effectively increased, the heat exchanger 200 can perform heat exchange better, and the heat exchange efficiency and the energy efficiency of the heat exchanger 200 are improved.
In an embodiment of the air outlet device of the present invention, as shown in fig. 1 to 5, the distance between the flow blocking ring 30 and the axial flow wind wheel 20 is defined as D, and D is 6mm < 20mm. In this way, on the one hand, by controlling the distance D between the flow blocking ring 30 and the axial flow wind wheel 20 to be not more than 20mm, the situation that the height of the contact point between the water drop at the high point B (located in the air duct 10) and the fan blade is too low and too close to the center of the axial flow wind wheel 20 when the water drop is sucked to the axial flow wind wheel 20 under the action of static pressure can be effectively avoided, so that the situations of too bad discrete atomization and too small range sprayed to the heat exchanger 200 caused by the too bad discrete atomization are avoided. That is, if the distance D between the flow blocking ring 30 and the axial flow wind wheel 20 exceeds 20mm, the height of the contact point between the water droplet at the high point B (located in the air duct 10) and the fan blade is too low and too close to the center of the axial flow wind wheel 20 when the water droplet is sucked to the axial flow wind wheel 20 under the action of static pressure, and at this time, the water droplet is scattered and atomized too poorly and the range sprayed to the heat exchanger 200 is too small, which is not beneficial to effectively improving the heat exchange efficiency and energy efficiency of the heat exchanger 200.
On the other hand, by controlling the distance D between the flow blocking ring 30 and the axial flow wind wheel 20 to be not less than 6mm, the possibility that the axial flow wind wheel 20 collides or extrudes with the flow blocking ring 30 due to the clearance of structural fit along the axial displacement of the air duct 10 in the running process can be effectively reduced, and the safety distance between the flow blocking ring 30 and the axial flow wind wheel 20 is ensured. That is, if the distance D between the flow blocking ring 30 and the axial flow wind wheel 20 is less than 6mm, the probability that the axial flow wind wheel 20 moves along the axial direction of the air duct 10 and collides or extrudes with the flow blocking ring 30 during operation due to the clearance of structural fit will greatly rise, thereby affecting the operation of the axial flow wind wheel 20 and damaging the stability and reliability of the air outlet device 100. It will be appreciated that in practical applications, the distance D of the baffle ring 30 from the axial flow wind rotor 20 may be 6mm, 7mm, 8mm, 10mm, 15mm, 20mm, etc.
As shown in fig. 1 to 5, in an embodiment of the air outlet device of the present invention, the water supply structure 40 includes a water receiving tray, the air duct 10 is disposed in the water receiving tray, and at least a portion of the water supply area 11 is not higher than a side wall of the water receiving tray. Thus, the water supply structure 40 is effectively simplified, so that the structure is simple, the production and the manufacture are convenient, the assembly is convenient, excessive other parts are not introduced, and the cost is lower. And meanwhile, the method has higher stability and reliability.
Further, the height difference h between the lowest part of the water supply area 11 and the bottom wall of the water receiving tray is not more than 6mm. In this embodiment, the water collector is horizontally disposed and is used for containing condensed water. The air duct 10 is arranged in the water receiving disc, and at least part of the water supply area 11 is not higher than the side wall of the water receiving disc. Thus, when the axial flow wind wheel 20 rotates at a high speed, the condensed water in the water receiving disc can "climb" the water supply area 11 on the inner surface of the wind guiding ring due to the action of the surface tension of the liquid, the centrifugal action and the siphon effect of the axial flow wind wheel 20. Because the maximum diameter of water drops which can be formed by the water under the action of surface tension is 4mm to 5mm, in order to facilitate less water in the water receiving disc to 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 disc is not more than 6mm, and in practical application, the height difference can be 1mm, 2mm, 3mm, 4mm, 5mm or 6mm.
As shown in fig. 1 to 5, 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 disposed opposite to each other, 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 into the air duct 10 from the air outlet 13 of the air duct 10 and is accommodated in the air duct 10. In this way, on one hand, a matching structure between the inner wall surface of the air duct 10 and the fan blades of the axial flow wind wheel 20 is formed, which is favorable for the fan blades to cut air, effectively increases the air quantity of the air outlet device 100, and makes the air outlet of the air outlet device 100 more concentrated, so that the heat exchanger 200 can perform heat exchange better, and the heat exchange efficiency of the heat exchanger 200 is improved; on the other hand, the fan blades of the axial flow wind wheel 20 can be more easy to receive 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 fan blades is better, and finer microbeads are obtained, so that the heat exchange process with 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 5, 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 facing away from the air inlet side thereof protrudes from the air outlet 13 of the air duct 10. Therefore, on one hand, the microbeads obtained after the water drops are discretely atomized by the fan blades can be effectively prevented from being intercepted by the inner wall surface of the air duct 10, so that more microbeads can be sprayed to the heat exchanger 200, and the heat exchange efficiency and 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 5, in an embodiment of the air outlet device of the present invention, a water ring 60 is disposed around the outer edge of the air outlet side, and the bottom of the water ring 60 extends into the water receiving tray.
Specifically, the water ring 60 is generally in a ring structure, the air outlet side of the axial flow wind wheel 20 is located at a hollowed position in the middle of the water ring 60, and the inner edge of the water ring 60 is disposed around the air outlet side of the axial flow wind wheel 20 and fixedly connected with each fan blade of the axial flow wind wheel 20, so that the water ring 60 and the axial flow wind wheel 20 are coaxially disposed. At this time, the water ring 60 is vertically disposed, and the lowest position of the inner edge of the bottom thereof is not higher than the sidewall of the water pan.
In this way, 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 will take up the water in the water receiving tray, and this water will be blown to the heat exchanger 200 by the axial flow wind wheel 20, and further "water cooling" is performed to the heat exchanger 200, so as to improve the heat exchange efficiency and energy efficiency of the heat exchanger 200.
As shown in FIGS. 1 to 5, in an embodiment of the air outlet device of the present invention, the distance E between the water ring 60 and the air outlet 13 is defined as E, and E is 10mm or less and 20mm or less. Thus, on one hand, by controlling the distance E between the water-beating ring 60 and the air outlet 13 to be not less than 10mm, the safety distance between the water-beating ring 60 and the air duct 10 can be ensured, so that the possibility that the water-beating ring 60 collides or extrudes with the air duct 10 due to the axial displacement of the air duct 10 along the clearance matched with the structure when the water-beating ring 60 runs together with the axial flow wind wheel 20 is reduced. That is, if the distance E between the water ring 60 and the air outlet 13 is less than 10mm, the probability of collision or extrusion between the water ring 60 and 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 60 and the axial flow wind wheel 20 are operated together will greatly increase, thereby affecting the operation of the axial flow wind wheel 20 and the water ring 60 and damaging the stability and reliability of the air outlet device 100. On the other hand, by controlling the distance E between the water ring 60 and the air outlet 13 to be not more than 20mm, the water carried by the water ring 60 can be ensured to obtain larger wind power and blow to the heat exchanger 200, so that the water can cover a wider range on the heat exchanger 200, and the heat exchange efficiency and energy efficiency of the heat exchanger 200 are improved. It will be appreciated that in practice, the spacing E of the water ring 60 from the air outlet 13 may be 10mm, 11mm, 12mm, 13mm, 15mm, 18mm, 19mm, 20mm, etc.
The invention also provides an air treatment device 1000, and the air treatment device 1000 comprises a heat exchanger 200 and the air outlet device 100, and the specific structure of the air outlet device 100 is detailed in the previous embodiment. Because the air treatment device 1000 adopts all the technical solutions of all the foregoing embodiments, at least all the beneficial effects brought by all the technical solutions of all the foregoing embodiments are not described in detail herein.

Referring to fig. 1 to 5, in an embodiment of the present invention, a water supply structure 40 of an air outlet device 100 is a chassis, and the chassis is horizontally disposed for containing water (such as condensed water). The air treatment device 1000 further comprises a bracket 300 fixed on the chassis, a mounting hole is further formed on the bracket 300, a motor 400 is further arranged in the mounting hole, and an output shaft of the motor 400 is connected with the axial flow wind wheel 20, so that the axial flow wind wheel 20 is driven to rotate. The air treatment device 1000 further includes a housing covering the chassis, so as to facilitate protection of the air outlet device 100, the heat exchanger 200, and the like. The air outlet of the air treatment device 1000 may be provided in the front panel, the back panel, or the side panel of the housing, so long as the air outlet is facilitated, and the heat exchanger 200 is provided before the air outlet in the air flow direction.
