[0002] As we all know, air-conditioning units generate a large amount of condensed water during operation. This condensed water is mostly collected in a water collection tray and then discharged. In cold weather such as winter, this condensed water is prone to freeze in the water collection tray and block the drain outlet, affecting the smooth discharge of the condensed water. The problem of freezing in the water collection tray needs to be solved urgently.

[0026] See also Figure 1-6 The utility model is a drainage device for an air-conditioning unit, comprising a frame 1, a water collecting bucket 2, a water guide groove 3, a water collecting tank 4, a pressure pump 5, a pressure-stabilizing tank 6, a spraying and flushing assembly and a vibrating ice-breaking mechanism installed on the water collecting bucket 2. A water inlet is provided on the top of the water collecting tank 4. Condensed water flowing out of the water collecting bucket 2 is introduced into the water collecting tank 4 from the water inlet through the water guide groove 3.

[0027] Specifically, the vibration ice-breaking mechanism includes a mounting seat 11, a swing arm 12 hingedly mounted on the mounting seat 11, a percussion hammer 13 mounted on the swing arm 12, an elastic support member 14, and a driving assembly for driving the swing arm 12 to reciprocate, one end of the elastic support member 14 is hinged to the mounting seat 11, and the other end of the elastic support member 14 is hinged to the swing arm 12, the driving assembly includes an eccentric driving member 15 and a rotary driver 16 for providing power for the rotation of the eccentric driving member 15, and a protrusion 17 in contact with the eccentric driving member 15 is provided on the driving swing arm 12; further, the rotary driver 16 can be a motor alone; or a motor and a transmission belt, etc., and the output end of the motor is connected to the eccentric driving member 15 through the transmission belt, etc. Transmission connection; the elastic support member 14 is preferably a telescopic rod and a spring sleeved on the extended end of the telescopic rod; the elastic support member 14 can also be a spring or other equivalent member with elastic recovery effect alone; when an ice layer appears in the water collecting bucket 2, the eccentric driving member 15 can be driven to rotate by the rotating driver 16, so that the eccentric driving member 15 and the protrusion 17 are in reciprocating contact, and the driving swing arm 12 drives the percussion hammer 13 to perform a reciprocating percussion action, and the ice layer is broken under the vibration and percussion action of the percussion hammer 13; as a preference, the vibrating ice-breaking mechanism is installed at the bottom of the water collecting bucket 2; in another embodiment, the vibrating ice-breaking mechanism can also be installed in the water collecting bucket 2, and directly contact the ice layer through the percussion hammer 13 to improve the ice-breaking efficiency and effect.

[0032] Specifically, a filter plate 24 is installed at the water inlet of the water collecting tank 4; the filter plate 24 can filter the crushed ice or other debris in the flowing condensed water to reduce the entry of the crushed ice and other debris into the water collecting tank 4.

The pressure pump 5 draws the clean water after static sedimentation in the water collecting box 4 into the pressure-stabilizing tank 6. With the injection of clean water, the pressure in the pressure-stabilizing tank 6 increases. When the temperature drops or the water collecting bucket 2 needs to be cleaned, the electric valve 10 opens, and the clean water in the pressure-stabilizing tank 6 is sprayed into the water collecting bucket 2 through the connecting pipe 7 and the circular pipe 8, producing an impact effect on the water collecting bucket 2. When ice crushing is required, the water collecting bucket 2 can be knocked by the vibrating ice-breaking mechanism to break the ice layer. The broken ice cubes can be intercepted by the filter plate 24 and then processed uniformly.
