As shown in fig. 1 to 5, in an embodiment of the water distribution device 100 of the present application, the water distribution device 100 includes:
a water storage structure 10;
the water pumping structure 20 is at least partially arranged in the water storage structure 10 and is used for pumping water in the water storage structure 10;

The following description will be made taking the horizontal setting of the water distribution device 100 as an example:
specifically, the water storage structure 10 may be a tray structure, a box structure, or a tank structure, that is, the upper surface of the water storage structure 10 is concavely provided with a water storage space for storing water. Further, the water storage structure 10 may be a chassis of the air treatment apparatus 1000 such as a window air conditioner, an air conditioner outdoor unit, a mobile air conditioner, a humidifier, or may be a structure (for example, a water receiving tank, a water receiving tray, a water receiving box, etc.) which is provided exclusively in the air treatment apparatus 1000 such as a window air conditioner, an air conditioner outdoor unit, a mobile air conditioner, a humidifier, etc. and which can function as a water storage. The water in the water storage structure 10 may be condensed water on the indoor side of the air treatment device 1000 such as a window air conditioner, an air conditioner outdoor unit, a mobile air conditioner, or the like, or may be humidified water of a humidifier, or may be tap water, rainwater, or other water bodies.

Further, the water-beating ring can rotate around its axis so that its bottom lifts up the water in the water storage structure 10. Of course, in order to enable the water-beating ring to rotate about its axis, the water distribution device 100 further comprises a driving assembly for driving the water-beating ring to rotate about its central axis. In this embodiment, the driving component is an axial flow fan 60, the axial flow fan 60 includes a motor 61 and an axial flow wind wheel 63, and the water-beating ring is circumferentially disposed at the outer edge of the axial flow wind wheel 63. When the axial flow fan 60 is operated, the motor 61 drives the axial flow wind wheel 63 to rotate, and the axial flow wind wheel 63 drives the water pumping ring to rotate, so that the bottom of the water pumping ring can pump up water in the water storage structure 10. Of course, in other embodiments, the drive assembly may be the motor 61; at this time, the water-spraying ring can be sleeved on the output shaft of the motor 61, and when the motor 61 operates, the motor 61 drives the water-spraying ring to rotate. Alternatively, the drive assembly may be a combination of motor 61, gears and a ring gear; at the moment, the gear ring can be arranged around the water-beating ring along the circumferential direction of the water-beating ring and is fixedly arranged on the water-beating ring; the gear can be sleeved on the output shaft of the motor 61 and meshed with the gear ring; when the motor 61 is operated, the motor 61 drives the water-beating ring to rotate through the cooperation of the gear and the gear ring. Of course, those skilled in the art may implement other reasonable and effective embodiments according to the concepts of the present application, and will not be further described herein.
In addition, the water-beating structure 20 may be a water-beating plate, a water-beating wheel or other reasonable and effective water-beating structure 20. The corresponding driving assembly can adopt a crank rocker mechanism driven by a motor 61 to enable one end of the strip-shaped water beating plate to swing highly, so as to contact and beat up water in the water storage structure 10; the motor 61 may also be directly used to drive the rotation of the water-filling wheel so that the outer edge of the water-filling wheel contacts and lifts the water in the water storage structure 10 during the rotation process. Of course, other driving components corresponding to the water pumping structure 20 may be reasonably and effectively arranged, and will not be described in detail herein.
A part of the water collecting and distributing structure 30 is arranged above the water beating structure 20 and is used for collecting water in the water storing structure 10 beaten by the water beating structure 20; meanwhile, a part of the water collecting and distributing structure 30 is positioned above the humidifying device 200 and used for guiding the collected water in the water storage structure 10 to the humidifying device 200. The water may be directed to the humidifying device 200 vertically from directly above the humidifying device 200, or may be directed to the humidifying device 200 obliquely from above the humidifying device 200. Specifically, the water collecting and distributing structure 30 may be a plate-like structure, which is disposed obliquely above the water beating structure 20 and the humidified device 200 with its plate surface at an angle to the horizontal plane, and whose plate surface height gradually decreases in the direction from the water beating structure 20 to the humidified device 200. At this time, the lower surface of the plate-shaped structure may collect water in the water storage structure 10 lifted up by the water-beating structure 20, and the water in the portion of the collected water storage structure 10 may flow to the upper side of the humidified device 200 along the lower surface of the plate-shaped structure, and finally drop over the humidified device 200 to contact the humidified device 200, thereby completing the humidifying process of the humidified device 200. Of course, a water baffle may be protruded towards the water storage structure 10 (downward) around the plate structure to obtain a cover structure integrating the water collecting function and the water distributing function, thereby realizing water collection and water distribution with higher efficiency.
In the movement process of the water pumping structure 20 after pumping water, part of water drops can splash and be adhered to the lower surface of the water collecting and distributing structure 30 above the water pumping structure 20, because the water pumping structure 20 pumps water from the water storage structure 10 at a lower temperature generally, particularly when the pumped water is condensed water formed on the surface of the heat exchanger, the temperature of air at the side is lower, and thus, after the air at the side, which is away from the water pumping structure 20 and has higher temperature, of the water collecting and distributing structure 30 is cooled, the water is easily condensed to form secondary condensed water. In this embodiment, the water collecting structure 40 is used for collecting and utilizing the secondary condensation water, so as to effectively prevent water accumulation in the air treatment device 1000 and save water resources.
Specifically, the water collecting structure 40 may also be a plate-like structure to receive the collected water by its upper surface, and then the water flows to the edge along its upper surface to drop to the water collecting and distributing structure 30; the water collecting and distributing structure may be a tray structure, a box structure, a tank structure or a box structure, so as to utilize the inner space to collect water, and then utilize the opening or the hole to distribute water drops to the water collecting and distributing structure 30. The water collecting structure 40 is conducted with the water collecting and distributing structure 30 at one side deviating from the water beating structure 20, or can be conducted by arranging a communicating pipe, a communicating groove and other structures, or can be conducted by arranging a communicating opening, a communicating hole and other structures after being connected with the water collecting and distributing structure 30, so that the condensed water can be gathered in the water collecting structure 40 by the surface of the water collecting and distributing structure 30 facing away from the water beating structure 20, and then is conducted back to the water collecting and distributing structure 30 from the water collecting structure 40 for being used by the humidifying device 200.
Therefore, it can be understood that, in the technical solution of this embodiment, by arranging at least part of the water pumping structure 20 in the water storage structure 10, the water in the water storage structure 10 can be pumped up by using the water pumping structure 20; then, by arranging at least the water collecting and distributing structure 30 above the water taking structure 20, the water taken up by the water collecting and distributing structure 30 can be collected; finally, by disposing at least the water collecting and distributing structure 30 above the humidified device 200 of the air treatment apparatus 1000, the collected water can be guided to the humidified device 200 by using the water collecting and distributing structure 30, and the humidifying process of the humidified device 200 can be completed. At this time, the humidified device 200 obtains an additional humidification process and an additional cooling capacity in the air treatment apparatus 1000, and greatly improves the humidifying and heat exchanging efficiency, so that the energy efficiency of the air treatment apparatus 1000 is improved.
