By the mode, the problem of low heating efficiency of the electric heater can be effectively solved. The spray portion 113 sprays mist liquid, and the area of spraying is bigger than the area of the columnar liquid of water, and this kind of mode can effectual saving flow that the washing liquid used on the one hand, and on the other hand promotes abluent efficiency, and on the third hand, mist liquid water flow is less, and the waste liquid recovery box 1213 can be very abundant collect the waste liquid that produces among the cleaning process to with the waste liquid through recovery pipeline 1214 get into in second stock solution portion 1211. The situation that the waste liquid flees everywhere due to the fact that the waste liquid cannot be recovered in time is prevented.
This application is through carrying out purification treatment to the waste liquid of retrieving to with waste liquid input after the purification treatment to first stock solution portion in, form the abluent route of inner loop, carry out self-loopa repeated utilization to the waste liquid after the purification, practice thrift the washing water, and then realize zero liquid and discharge to the environment in, avoided the waste liquid that does not handle directly to arrange to the environment in and then the polluted environment. Be equipped with first sterilization module in waste water recovery purifies the subassembly, can kill the microorganism in the waste liquid. The cleaning liquid in the first liquid storage part is heated by the electric heater, so that the safety performance is high, the pollution is low, and the energy conservation and the environmental protection are realized. Set up the second module of disinfecting on waste water recovery box, because the injection part is installed on waste water recovery box, when treating the washing target and wash, can kill the microorganism on the washing target. Utilize the stoving subassembly to dry to the surrounding environment, prevent the sharp increase of ambient humidity, avoided providing the condition of breeding for the microorganism in the environment.
