The prevent invention comprises a non-returning pipe, pressure controller and pressure-resisting ring respectively, whose larger ring-shaped side exactly resists the water inlet edge of the non-returning pipe, in which some interlinked vents are designed on the larger ring-shaped side while a leakage-proof pad on the ladder-shaped side for the pressure-resisting ring. In that way, the pressure-resisting ring is pushed towards the pressure control and the leakage-proof pad exactly would be absorbed by the vacuum at the edge of central hole in the case of water's access to the non-returning pipe. And the pressure-resisting ring can eliminate the vacuum absorption with its gravity and air suction to form an unobstructed water flow and block backward the water inlet edge of the non-returning pipe to prevent the water flow's reflux from access to the interior of the non-returning pipe for longer service life of water transport pipeline and balance the returning water operation safety. Thereby, it not only would not easily be involved in denaturation and failure, but also has simple structure and exact operation besides its easy assembly.

The invention relates to a drainage assembly of an indoor unit of an air conditioner. The drainage assembly comprises a drainage assembly and a blowing structure, wherein the drainage chamber comprises a water outlet; the blowing structure can generate an air flow; the air flow can push a liquid and/or a solid in the drainage channel to move to the water outlet and/or to move out of the drainage channel through the water outlet. By arranging the blowing structure to provide auxiliary power to movement of the liquid (for example, condensate water) and/or the solid (for example, foreign matterssuch as dust and impurities) in the drainage channel, the flowing speed of water in the drainage channel can be accelerated, the drainage speed of the drainage channel is accelerated and accumulated water is prevented from being generated in the drainage channel; moreover, solid foreign matters in the drainage channel are promoted to be discharged to solve the problems that the water flow is unsmooth and a lot of condensate water is accumulated in the drainage channel as the foreign matters are prevented from blocking the water outlet of the drainage channel, so that the hidden danger of waterleakage of the indoor unit of the air conditioner is eliminated.
