As shown in fig. 2, the cleaning seat 20 includes a clean water tank 26, a dirty water tank 27, a water receiving tank 25, and a cleaning part 23 located above the water receiving tank 25. The shell of wash seat 20 divide into ramp portion and vertical portion, and the bottom surface of ramp portion stands on ground as wash seat 20's footing, and the up end of ramp portion is an inclined plane, and the one end on inclined plane extends to ground, and the other end on inclined plane upwards extends to connect vertical portion to one side, and vertical portion is located the top of ramp portion. A water receiving groove 25 is arranged in the inclined platform part, an opening 22 is arranged above the water receiving groove 25 and corresponds to the inclined surface, a cleaning part 23 is arranged in the opening 22, and when the robot 10 moves upwards from the inclined surface to the position of the opening 22, the mop cloth 11 and the cleaning part are in mutual friction contact. Inside said upright is provided an electronic control module (not shown in the figures), a clean water tank 26 and a dirty water tank 27, the clean water tank 26 being connected to the washing part 23 by a pipe to supply clean water from the clean water tank 26 to the washing part 23, so that the washing part 23 can spray clean water to wash the mop 11 of the robot 10. An electrically controlled valve and a hydraulic pump are also provided in the clean water tank 26, the hydraulic pump increasing the pressure of the water supplied from the clean water tank 26 to the mop 23 to allow the mop 11 to be washed better by the mop 23, and the electrically controlled valve controlling the clean water tank 26 to supply water to the mop 23 or to interrupt the supply of water. When the clean water tank 26 is ready to run out, the wash station 20 alerts the user to fill the clean water tank 26. The sewage tank 27 is also connected to the water receiving tank 25 through a pipe, a water suction pump is arranged in the water receiving tank 25, and when the water receiving tank 25 receives water leaked from the cleaning part 23 and reaches a certain height, the water suction pump is started to pump out the water in the water receiving tank 25 to the sewage tank 27 through the pipe. When the wastewater in the wastewater tank 27 is ready to be stored, the washing base 20 gives an alarm to prompt the user to treat the wastewater tank 27, and the set water level may be set to two-thirds or three-quarters of the depth of the wastewater tank 27. By adopting the structure of the cleaning seat 20, sewage can flow out in time, the mop 11 can not be repeatedly washed by the sewage, the mop 11 can be directly washed by clean water, and the cleaning effect is better.
As another implementation method, the cleaning seat 20 may not be provided with the clean water tank 26 and the dirty water tank 27, the cleaning part 23 may be directly connected to an external water source through a pipe, and the water receiving tank 25 may directly discharge the dirty water to the outside through a pipe. This further simplifies the construction of the wash seat 20 and reduces product costs.
The washing seat 20 is further provided with a guiding signal emitting part 21 for guiding the robot 10 to sit on the seat, and a detecting part 24 for detecting whether the robot 10 sits on the seat in place. The guiding signal emitting part 21 adopts an infrared signal sensor, the structural form of the guiding signal emitting part is the same as the infrared return seat structure of the charging seat of the existing sweeping robot 10, and the control method and principle for guiding the robot 10 to return the seat are also the same, which are not described herein again. The detection unit 24 may be an infrared signal sensor, or may be other components such as a mechanical travel switch. When robot 10 is moved to a position where cleaning of mop 11 is possible, i.e. mop 11 and cleaning part 23 are in contact with each other, detection part 24 is triggered, indicating that robot 10 has been seated in place.
After the robot 10 automatically mops the floor for a period of time or within a certain area range, when it is determined that the mop 11 needs to be cleaned, a back seat cleaning signal is sent. After receiving the seat returning cleaning signal from the robot 10, the cleaning seat 20 controls the guide signal transmitting unit 21 to transmit a guide signal. Without receiving the guidance signal, the robot 10 will first navigate to the orientation of the wash seat 20 based on the map constructed during the cleaning process. In the navigation process, the robot 10 always detects whether a guiding signal is received, and performs seating according to the detected guiding signal when the guiding signal is received, and the specific seating manner is the same as the manner of the existing floor sweeping robot 10 seating-back charging manner, which is not described herein again. The cleaning seat 20 controls the cleaning part 23 to spray water after receiving the upper seat trigger signal of the detection part 24, wherein the upper seat trigger signal is a signal generated by triggering the detection part 24 when the robot 10 moves from the ground onto the cleaning seat 20, and when receiving the signal, the cleaning seat 20 can know that the robot 10 is in place and can perform the cleaning operation, so the cleaning part 23 is controlled to start spraying water. Robot 10 then reciprocates back and forth in a predetermined motion to rub mop 11 against cleaning portion 23 of cleaning base 20 to remove soil from mop 11. The preset action is designed in advance according to a control program of the robot 10, and in the embodiment, the preset action refers to controlling the robot 10 to walk forwards for a certain distance and then backwards for a certain distance, so that the robot moves back and forth. The mop 11 is always kept in contact with the cleaning part 23 during a certain distance of travel within the length of the cleaning part 23, i.e. during the back and forth reciprocating movement of the robot 10. The robot 10 moves back and forth in a reciprocating manner for a predetermined time or a predetermined number of times and then retreats from the cleaning seat 20, and at this time, the cleaning seat 20 controls the cleaning part 23 to stop spraying water after receiving the off-seat trigger signal of the detecting part 24. The preset time and the preset times can be set correspondingly according to different product requirements, for example, the preset times is set to 30 times or 40 times, and the preset time is set to 50 seconds or 60 seconds. The off-seat trigger signal is a signal generated by the trigger detecting unit 24 when the robot 10 is retreated from the wash seat 20 and is off-seat, and when the wash seat 20 receives the signal, it is known that the robot 10 has left the wash seat 20, and the washing operation does not need to be continued, so that the washing unit 23 is controlled to stop spraying water. After the robot 10 leaves the wash station 20, the mopping task may continue.
In the system of the embodiment, the robot 10 can automatically return to the cleaning seat 20 to automatically clean the dirty mop 11, the intelligent degree is high, the labor burden of a user is effectively reduced, and the convenience and the practicability of product use are improved. Above all, the present embodiment can simplify the self-cleaning structure in the system, and it only needs to control the robot 10 to reciprocate back and forth on the cleaning seat 20 and control the cleaning part 23 to spray water to implement automatic scrubbing of the mop 11 without adding an additional cleaning action mechanism. The operation only needs to improve the control program in the aspect of software, and does not need to increase the hardware cost, so that the cost of the system is greatly reduced, and the cost performance of the system is improved.
As one embodiment, as shown in fig. 3, the cleaning part 23 includes a plate-shaped body, two ends of the plate-shaped body are detachably and fixedly connected to two sides of the opening 22 of the cleaning seat 20, the upper end surface of the plate-shaped body is provided with a plurality of sets of scraping strips, the shapes and the numbers of the scraping strips can be set according to the product design requirements, and the structures indicated by numbers 231 and 232 in fig. 3 are a set of scraping strips. The middle of each group of the scraping strips is provided with a plurality of water spraying ports 235, and each water spraying port 235 is communicated to the water inlet 233 of the plate-shaped main body through a water conveying channel 234 arranged in the plate-shaped main body. The scrubbing effect of the mop on the cleaning part can be improved by the structure of the scraping strip and the water spraying opening.
Specifically, as shown in fig. 3, the cross section of the scraping strip is in a sharp-angled shape, so that the friction stress between the mop and the cleaning part can be improved, and the scrubbing effect is better. Every group of scraping strip includes two scraping strips that use the water jet to set up as axis mirror symmetry, and the closed angle of these two scraping strips extends towards oblique top, like this, no matter the robot is forward motion, still backward motion, and its mop can both carry out powerful frictional contact with washing portion, has further improved the effect of scrubbing.
Particularly, the scraping strip is a hard plastic structure integrally injection-molded with the plate-shaped main body, so that the production and the manufacturing are convenient, the complex assembling procedures are reduced, and the product quality is stable and reliable.
As one of the embodiments, as shown in fig. 2, the cleaning seat 20 further includes a clean water tank 26 and a dirty water tank 27, the clean water tank 26 is connected to the water inlet 233 of the cleaning part 23 through a pipe to supply clean water in the clean water tank 26 to the cleaning part 23, so that the cleaning part 23 can spray clean water to flush the mop 11 of the robot 10. An electromagnetic valve for controlling water outlet is arranged at the water outlet of the clean water tank 26, a main control module of the cleaning seat is electrically connected with the electromagnetic valve, and the cleaning seat 20 can send a control signal to the electromagnetic valve through the main control module to control the water outlet of the clean water tank or stop the water outlet. The sewage tank 27 is also connected to the water receiving tank 25 through a pipe, a water suction pump is arranged in the water receiving tank 25, and when the water receiving tank 25 receives water leaked from the cleaning part 23 and reaches a preset height, the main control module controls the water suction pump to be started, so that the water in the water receiving tank 25 is pumped out to the sewage tank 27 through the pipe. The preset height is set when the product is designed, different values can be set according to different product requirements, for example, the preset height can be set to be two-third of the depth of the water receiving tank, or to be half of the depth of the water receiving tank, and the like. The cleaning seat of the embodiment can improve the independence of the cleaning seat by configuring the clean water tank 26 and the sewage tank 27, and is convenient to move the cleaning seat.
In one embodiment, the cleaning seat is further provided with a charging port, and when the robot needs to be charged, the robot can be guided by the cleaning seat to charge the upper seat.
As shown in fig. 4, a self-cleaning control method of a self-cleaning robot system, which is the self-cleaning robot system described in the above embodiments. The method comprises the following steps 1 to 6. In step 1, after the cleaning robot mops the floor for a period of time or a certain area range, the cleaning robot judges that the mop cloth is dirty and needs to be cleaned, so that the cleaning robot sends a seat returning cleaning signal. In step 2, after the cleaning seat receives the seat returning cleaning signal sent by the cleaning robot, the cleaning seat controls the guide signal sending part to send out a guide signal. The robot can navigate to the position of the cleaning seat according to the map constructed in the cleaning process under the condition that the robot does not receive the guide signal. In the navigation process, the robot always detects whether a guiding signal is received, and when the guiding signal is received, the robot enters step 3. In step 3, the cleaning robot performs seating according to the detected guiding signal, and the specific seating mode is the same as the mode of recharging the existing sweeping robot, which is not described herein again. In step 4, the cleaning seat controls the cleaning unit to spray water after receiving the trigger signal for the upper seat of the cleaning robot. The upper seat trigger signal is a signal generated by the trigger detection part when the robot moves from the ground to the cleaning seat, and when the cleaning seat receives the signal, the cleaning seat can know that the robot is in place and can perform cleaning operation, so that the cleaning part is controlled to start spraying water. In step 5, the cleaning robot performs a back and forth reciprocating motion according to a preset motion to make the mop and the cleaning part perform reciprocating friction to remove the stains in the mop. The preset action is designed in advance according to a control program of the robot, and the preset action refers to controlling the robot to walk forwards for a certain distance and then backwards for a certain distance, so that the robot reciprocates back and forth. The certain distance of walking is in the length scope of cleaning part, namely the robot is in the process of reciprocating back and forth, and the mop keeps contact with cleaning part all the time. According to the control method, the robot can automatically return to the cleaning seat to automatically clean the dirty mop, the intelligent degree is high, the labor burden of a user is effectively relieved, and the convenience and the practicability of product use are improved. In addition, by adopting the control method, the self-cleaning structure in the system can be simplified, an additional cleaning action mechanism is not needed, and the automatic scrubbing of the mop can be realized only by controlling the robot to reciprocate back and forth on the cleaning seat and controlling the cleaning part to spray water. The operation only needs to improve the control program in the aspect of software, and does not need to increase the hardware cost, so that the cost of the system is greatly reduced, and the cost performance of the system is improved.
As one embodiment, after the step 5, the following steps 6 and 7 are also included. In step 6, the robot moves back and forth for a preset number of times or for a preset time, retreats from the cleaning seat and leaves the seat.
