As shown in fig. 1, the present embodiment provides a liquid discharge structure, which includes a tee 310 and a drain 340; flanges 200 are arranged at two ends of the three-way pipe 310, and branch pipes of the three-way pipe 310 are arranged downwards and are communicated with accommodating grooves; the drain pipe 340 is communicated with the storage groove and used for discharging liquid in the storage groove, a first valve 341 is arranged at one end, close to the storage groove, of the drain pipe 340, and a second valve 342 is arranged at one end, away from the storage groove, of the drain pipe 340. The three-way pipe 310, the accommodating groove and the drain pipe 340 are arranged, so that the operations of accommodating and discharging the accumulated liquid can be completed quickly; through setting up first valve 341 and second valve 342, not only reduced interior hourglass, still made things convenient for the change of component, reduced the valve and suffered the influence of erodeing, prolonged drainage structures's life, avoided the risk that hydrops blockked clean out pipe 340. The liquid discharge efficiency of the liquid discharge structure is improved, and the liquid discharge effect is guaranteed.

Specifically, when the effusion discharge operation is performed, the first valve 341 is opened first, and then the second valve 342 is opened; when the effusion discharge operation is stopped, the second valve 342 is closed, the first valve 341 is closed, the second valve 342 is opened, and the second valve 342 is closed again after the effusion between the first valve 341 and the second valve 342 is discharged completely. The method ensures the sealing performance of the first valve 341, prolongs the service life of the first valve 341, and greatly reduces the risk of the accumulated liquid blocking the drain pipe 340.

Preferably, the flange 200 is arranged on the branch pipe of the three-way pipe 310, the flange 200 is arranged at the top end of the accommodating groove, and the three-way pipe 310 is detachably connected with the accommodating groove. The arrangement of the flange 200 enlarges the application range of the three-way pipe 310 and the accommodating groove, and provides more connection modes for the three-way pipe 310 and the accommodating groove; the detachable connection of the two facilitates the replacement and cleaning operation of operators.
