It will be appreciated by those skilled in the art that the self-cleaning method of the surface cleaning system described herein has at least the following benefits:
1. c, adding a step C in the automatic cleaning process of the floor cleaning machine, namely a stage of cleaning the sewage sucking channel: the soil pick-up motor is opened, the suction power of soil pick-up motor is P1, and the suction power setting of soil pick-up motor is between 0.3P and is less than or equal to P1 < 0.5P for the soil pick-up device is with the washing liquid through the soil pick-up mouth inhale to the soil pick-up passageway in, the washing liquid flows in the soil pick-up passageway, with constantly erode soil pick-up passageway inner wall and soil pick-up mouth, thereby make the cleaning roller realize the back of self-cleaning in the washing tank, also realized the self-cleaning to soil pick-up mouth and soil pick-up passageway, reduced user's cleaning, promoted user experience. Moreover, the self-cleaning of the sewage suction channel and the sewage suction port covers the sewage suction port and most of the area of the sewage suction channel, so that the sewage suction port and the sewage suction channel are well cleaned, the adhesion of dirt, mildew and even generation of peculiar smell caused by long-time uncleaning of the inner wall of the sewage suction channel and the vicinity of the sewage suction port are avoided, and the secondary cleaning work of a user is reduced.
When the power of the sewage suction motor is adjusted, so that the actual suction power is P1P or more and is not less than 0.5P, under the negative pressure action of the sewage suction motor, the cleaning solution directly and quickly fills the pipeline along the sewage suction channel, rises to the highest point in the sewage suction channel or is sucked into the sewage containing barrel, has no flowing space in the sewage suction channel, and only can take away floating dust or sewage on the surface of the inner wall of the sewage suction channel, the impact force of the cleaning solution on the inner wall of the sewage suction channel is insufficient, so that stubborn stains adhered to the sewage suction channel cannot be effectively infiltrated and cannot be taken away by water flow, and the cleaning effect on the sewage suction channel and a sewage suction port is poor. When the power of the sewage suction motor is adjusted to ensure that the actual suction power is P1 less than 0.3P, the suction power of the sewage suction motor is insufficient, the cleaning liquid can only stay near the sewage suction port and cannot enter the sewage suction channel, the sewage suction port can only be washed, and the sewage suction channel cannot be cleaned.
2. The length of the sewage suction channel is set to be equal to or more than 12cm and equal to or less than 24cm, and the length is matched with the power of the sewage suction motor, so that the cleaning liquid can effectively enter the sewage suction channel and flow in the sewage suction channel with the length, and the sewage suction port and the inner wall of the sewage suction channel are continuously cleaned. When the sewage suction motor is used for cleaning the sewage suction channel by adopting suction power of 0.3P, the cleaning liquid can rise into the sewage suction channel, rise from the top to the highest point in the sewage suction channel and flow down to the sewage suction port from the highest point, so that the inner wall of the sewage suction channel is repeatedly washed, resources are saved, and the cleaning effect of the sewage suction channel can be ensured; when the suction power of the sewage suction motor is less than 0.5P, the pressure of the cleaning liquid driven by the sewage suction motor is enough, the cleaning liquid can rise into the sewage suction channel and does not jump out of the sewage suction channel and flow in the sewage suction channel, the cleaning liquid can be concentrated in the sewage suction channel, the flow rate of liquid in the sewage suction channel in unit area per unit time is increased, enough impact force is generated to repeatedly wash the inner wall of the sewage suction channel, the structure of the surface cleaning machine is not required to be changed, the cleaning effect of the sewage suction channel is good, and the resource utilization is maximized; and when the dirty washing liquid or the surface cleaning machine clean ground after wasing the cleaning roller, the cleaning machine can hold dirty bucket with the quick suction of foul solution, accomplish the self-cleaning of cleaning roller or the cleaning work of scrubber, when guaranteeing the self-cleaning efficiency of clean and cleaning roller, again with soil pick-up mouth and soil pick-up passageway rinse thoroughly, make the utilization of resources maximize, and make organism simple structure volume reasonable, the simple easy clearance of installation of both having guaranteed the organism, do not need too powerful soil pick-up motor again.
When L is less than 12cm and the suction power is more than or equal to 0.5P, the cleaning liquid is directly pumped into the sewage suction barrel under the action of the suction motor, cannot stay in the sewage suction channel and repeatedly move up and down, and cannot achieve the effect of flushing the sewage suction channel;
when L is larger than 24cm and the suction power is smaller than 0.3P, the power of the sewage suction motor is not enough to drive the cleaning liquid to reach the upper end of the sewage suction channel, only the lower end and the sewage suction port in the sewage suction channel can be repeatedly washed, the cleaning dead angle at the upper end is still not enough, and the effect of thoroughly cleaning the sewage suction channel cannot be achieved.
3. Through will sewage suction motor drives the high H that the washing liquid rose in the soil pick-up passageway and sets for 0.3L be less than or equal to H < L for the soil pick-up motor is driving washing liquid during operation, can reach the 0.3L department of soil pick-up passageway at minimum, can not gush out the soil pick-up passageway moreover, thereby can make the washing liquid surge from top to bottom in the soil pick-up passageway, constantly assaults the soil pick-up passageway inner wall, has reached the effect of effectively wasing soil pick-up passageway inner wall and soil pick-up mouth. When H is less than 0.3L, the power of the sewage suction motor is insufficient, so that the cleaning liquid cannot continuously impact the inner wall of the sewage suction channel in the sewage suction channel, the upper end of the sewage suction channel is not cleaned in place, and a cleaning dead angle is left.
4. The suction power of the sewage suction motor is changed in a pulse type, sine wave type or step type waveform manner, so that the cleaning liquid forms regular up-and-down flow in the sewage suction channel and continuously washes the sewage suction port and the inner wall of the sewage suction channel; or the suction power of the sewage suction motor is alternatively changed by various waveforms, so that the cleaning liquid forms turbulent flow in the sewage suction channel and continuously washes the sewage suction port and the inner wall of the sewage suction channel. Make the liquid stream in the soil pick-up passageway can not form the turbulent flow, and strike each other between every strand of liquid stream, constantly efflux to soil pick-up passageway inner wall, the liquid stream refraction that intakes earlier comes back and the liquid stream that gets into after strikes once more, forms the torrent, constantly erodees soil pick-up mouth and soil pick-up passageway inner wall to the mesh with soil pick-up mouth and soil pick-up passageway sanitization has been reached.
