Description

Drainage assembly and heat pump equipment Technical Field The utility model relates to the technical field of heat pump equipment, in particular to a drainage assembly and heat pump equipment. Background In the operation process of the heat pump equipment, the fan operates to enable the chassis of the heat pump equipment to generate negative pressure, and under the action of the negative pressure, water in a drain pipe connected to the chassis can flow back, namely a suck-back phenomenon is generated, so that the heat pump equipment is difficult to drain. Meanwhile, after the water in the drain pipe is sucked to a certain height, the water can flow downwards again under the action of gravity, so that the water can oscillate back and forth in the drain pipe to generate noise, and the user is puzzled. Disclosure of utility model The present utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, the utility model provides the drainage assembly, which can prevent reverse suction, effectively reduce drainage noise and improve user experience. The utility model also provides heat pump equipment with the drainage assembly. The water draining assembly comprises a water draining pipe, a fixing seat and a water draining pipe, wherein the water draining pipe comprises a water inlet section, a bent pipe section and a water outlet section which are sequentially connected, an opening of a bent part of the bent pipe section is upwards arranged, the water inlet section and the water outlet section are positioned on the upper side of the bent pipe section, the fixing seat comprises a first fixing piece and a second fixing piece which are mutually connected, a first through groove and a second through groove are defined between the first fixing piece and the second fixing piece, the water inlet section penetrates through the first through groove, and the water outlet section penetrates through the second through groove. The drainage assembly has the advantages that the drainage pipe comprises the bent pipe section, the opening of the bent part of the bent pipe section is upwards, a certain amount of water can be stored in the bent pipe section, a liquid seal is formed, the integrity of the liquid seal can be maintained even if negative pressure exists in the chassis, external air is effectively prevented from being sucked into the drainage pipe, the water backflow prevention function is achieved, the water is prevented from oscillating back and forth in the drainage pipe, drainage noise is effectively reduced, and the user experience is improved.
