Background

At present, before dish washing machines on the market perform dish washing work, in order to avoid blockage caused by discharging solid kitchen waste, the large solid kitchen waste in the tableware needs to be manually pretreated in advance and then can be put into the dish washing machines for washing. The cleaning mode of the dishwasher is time-consuming and labor-consuming, and brings inconvenience to users, so that the user experience is reduced.

In contrast, chinese patent CN108185955A discloses a solid-liquid separator for a dish washer, which comprises a box, a high-pressure cleaning pipe, a rotary barrel, a spiral propulsion device, a feeding pipe, a transmission mechanism, a slag discharge pipe, a water tank, a water outlet, a nozzle and an ultrasonic vibrator. The rotary barrel and the spiral propelling device are simultaneously driven by the transmission mechanism to do centrifugal motion so as to separate solid kitchen waste from liquid. However, if the slag discharging pipeline is directly connected with the rotary barrel, when the transmission mechanism drives the rotary barrel and the spiral recommending device to do centrifugal motion, the slag discharging pipeline cannot be kept fixed, and can move circularly along with the rotary barrel, so that solid-liquid separation is difficult to realize. And if it slag tap pipeline and rotatory bucket are not directly continuous, the rubbish from cooking in the rotatory bucket has the problem of spilling hourglass from the clearance with in the slag tap pipeline, and difficult separation is thorough, and can only arrange rubbish again after having arranged water earlier, and the realization effect is relatively poor. Meanwhile, water and solid kitchen waste in the rotary barrel can be discharged from the slag discharge pipeline together, the solid kitchen waste and liquid are difficult to be thoroughly separated, and inconvenience is brought to subsequent treatment of the solid kitchen waste.
