Description

A cleaning robot and a matching cleaning table Technical Field

[0001] The utility model relates to the technical field of cleaning appliances, in particular to a cleaning robot and a matching cleaning table. Background Art

[0002] Existing sweeping robots and floor scrubbers still generally have some technical defects in mopping and garbage disposal. The following summarizes some of the main technical defects of existing sweeping robots and floor scrubbers:

[0003] 1. Most existing sweeping robots use two disc-shaped rotating mops to mop the floor. This results in a smaller area of ​​the mops in contact with the floor in the middle and on both sides, resulting in uneven mopping effect.

[0004] 2. Existing cleaning appliances such as sweeping robots, household floor scrubbers, and electric mops use roller brushes to clean the floor. When cleaning, water is flushed outside the roller brush, which makes it difficult to clean the dirt at the root of the roller brush, affecting the mopping effect.

[0005] 3. Most of the existing floor cleaning tools such as sweeping robots and household floor scrubbers leave some moisture on the ground after cleaning, which not only affects the cleaning effect but also may cause slips and falls to injure people.

[0006] 4. The existing household floor scrubbers are heavy to use because the suction fan, clean water box, sewage box and battery are all installed in the lower half of the handle. In addition, they cannot be put under furniture under normal circumstances, which seriously affects the scope of use.

[0007] 5. Household floor scrubbers generally only have scrubbing roller brushes but no sweeping components, including side brushes, sweeping roller brushes and trash boxes. They not only cannot suck in larger garbage such as paper balls, but also often cause blockage of the air intake, making them very inconvenient to use.

[0008] 6. Some existing sweeping robots have adopted a method of setting up a temporary trash bin at the charging place, which can suck the garbage in the trash box of the sweeping robot into the temporary trash bin. However, after a period of time, the trash bin is full and manual disposal of the garbage is still required. Summary of the Invention

[0009] In order to solve the above problems and defects of existing cleaning robots and supporting cleaning devices, the purpose of this utility model is to provide a cleaning robot and a supporting cleaning table with high mopping efficiency, wide application range, worry-free and labor-saving cleaning, and good mopping effect.

[0010] The present invention solves the above-mentioned technical problems of existing cleaning robots by adopting a technical solution: the cleaning robot comprises a cleaning robot frame assembly, an intelligent control walking assembly, a sweeping assembly, and a mopping assembly. The components of the cleaning robot are all mounted on the frame and arranged from front to back in the following order: a side brush, a sweeping roller brush, and a trash bin. Behind the trash bin is a water suction head with a mopping roller brush and a matching scraper blade. Behind this is a sewage tank, a clean water tank, a suction fan, a battery, and an onboard intelligent controller, which are centrally mounted on a tray frame. Both ends of the tray frame are mounted on the frame.

[0011] The side brush, sweeping roller brush and mopping roller brush are all equipped with drive motors and powered by batteries;

[0012] A water pump is installed in the clean water tank, and the water pump sprays water onto the mopping roller brush through a clean water hose and a flushing pipe with a row of flushing holes above the mopping roller brush;

[0013] A water scraper is installed above the mopping roller brush near the flush pipe to scrape the water from the mopping roller brush, and both ends of the water scraper are fixed on the inner wall of the squeegee head;

[0014] The mopping roller brush rotates to mop the floor, and the sewage scraped off by the wiper is then sucked into the sewage tank by the suction fan through the air flow;

[0015] A funnel is provided on the top of the sewage tank, and a one-way valve is provided at the mouth of the funnel to prevent sewage from overflowing;

[0016] A water retaining wall is provided inside the funnel to separate the air inlet area from the air outlet area to prevent sewage from entering the air outlet hose and then entering the suction fan along with the air flow;

[0017] An air inlet hose is provided on the top cover of the sewage tank at the air inlet area on one side of the retaining wall, and an air outlet hose is provided on the air outlet area on the other side of the retaining wall;

[0018] The air inlet hose of the sewage tank is connected to the air suction port on the top of the garbage box and the air suction port of the water suction head respectively; the inner side of the air suction port on the top surface of the garbage box is provided with filter material;

[0019] The sewage tank air outlet hose is connected to the suction fan;

[0020] A sewage discharge pipe is provided at the bottom of the sewage tank side, and a sewage discharge solenoid valve is provided on the sewage discharge pipe. The sewage discharge solenoid valve is controlled by an onboard intelligent controller;

[0021] There are running wheels under the frame, the two front ones are universal wheels and the two rear ones are drive wheels;

[0022] The cover is fixed to the frame and covers the entire components of the cleaning robot.

[0023] A further solution of the cleaning robot of the present invention is that a dust suction head is provided at the back of the garbage box, both ends of the dust suction head are fixed on the frame, the suction pipe of the dust suction head is connected to the air inlet hose of the sewage tank, and an auxiliary sweeping roller brush with its own motor is provided in the dust suction head.

[0024] A further solution of the cleaning robot of the utility model is that a small water suction scraper is provided at the back of the tray rack, and the air suction pipe of the small water suction scraper is connected to the air inlet area of ​​the sewage tank;

[0025] A sensor for sensing fluid waste is provided below the front facade of the cleaning robot. The sensor is electrically connected to the intelligent controller. When the sensor senses fluid waste, the intelligent controller turns the cleaning robot around, placing the small shovel head in front to clean the fluid waste. After cleaning, the head is turned back to prevent the sweeping component from being stuck with fluid waste and being unable to continue cleaning the floor.

[0026] A further solution of the cleaning robot of the present invention is that a hot air blower with the same width as the mopping brush is provided at the rear end of the frame. The upper half of the hot air blower is wider and is equipped with a row of small fans. Below the small fans are electric heating elements such as ceramic heating plates. The hot air nozzle in the lower half is narrower, and the hot air is blown out in a direction obliquely to the rear, which can dry the ground on the one hand and disinfect the ground at high temperature on the other.

[0027] A further solution of the cleaning robot of the present invention is that the garbage box has a movable bottom structure, the rear edge of the bottom of the garbage box is hinged to the lower edge of the rear vertical wall, and a vertically installed electric push rod is provided on the outside of one or both end faces of the garbage box, the motor end of the electric push rod is on the top, and the mounting hole of the motor end is hinged to the upper end of the end face of the garbage box through a rotating shaft; the telescopic end of the electric push rod is at the bottom, and its mounting hole is hinged to the rotating shaft on the end face of the bottom plate of the garbage box. When dumping garbage, the electric push rod extends to turn the bottom of the garbage box down, and after dumping the garbage, the electric push rod retracts to turn the bottom of the garbage box up and reset to close; the electric push rod is controlled by an intelligent controller.

[0028] A further solution of the cleaning robot of the utility model is that two parallel mopping roller brushes are provided inside the water suction head. The rotating shafts of the two mopping roller brushes are both tubular, and the rotating shaft covered by the wiping cloth is provided with a flushing mesh.

[0029] One end of the two tubular rotating shafts is closed, and the other end is sealed and connected to the clean water hard pipe through a seal. The clean water hard pipe is connected to the clean water hose, and the clean water hose is connected to the water outlet of the water pump in the clean water tank;

[0030] Clean water enters the water-permeable wiping cloth from the flushing mesh of the tubular shaft. The centrifugal force generated by the rotation of the mopping brush and the pressure generated by the water pump on the water can cause the clean water to be thrown out from the inside to the outside at high speed, forming a bottom-up flushing method for the mopping brush from the inside out.

[0031] A sealed recess for placing the motor is provided in the tubular rotating shaft at the end of the mopping roller brush where the water inlet pipe is not installed. A water-permeable gap is provided between the outer wall of the recess and the inner wall of the tubular rotating shaft. The motor is placed in the recess and fixedly connected to the inner wall of the recess. The motor shaft is fixed to the frame. The rotation of the motor housing drives the mopping roller brush to rotate.

[0032] A V-shaped scraper with a center gap is provided between the two mopping brushes. The two mopping brushes rotate downward on the contact side of the V-shaped scraper. The two long sides of the V-shaped scraper scrape the mopping brushes respectively, so that the dirty water scraped off the mopping brushes can quickly and completely separate from the mopping brushes, and then flow to the center gap. Finally, the dirty water is carried into the sewage tank by the airflow coming up from the center gap.

[0033] A further solution of the cleaning robot of the present invention is that both ends of the water suction scraper head are provided with an air intake control baffle for controlling the air intake, and an air inlet is provided at both ends and the middle of the air intake control baffle. The airflow coming in from the air inlets at both ends respectively takes away the sewage scraped up by the front and rear scraping strips of the corresponding water suction scraper head, and the middle air inlet takes away the sewage in the middle seam of the V-shaped scraper.

[0034] A further solution of the cleaning robot of the present invention is that a water filling pipe is provided at the upper end of the clean water tank, and a one-way valve is provided on the water filling pipe to prevent the clean water from overflowing. The water filling pipe opens on the front facade of the cleaning robot, and the water filling port is in a trumpet shape;

[0035] A water level sensor is provided in the clean water tank, and a water level sensor contact electrically connected to the water level sensor and a battery charging contact are provided on the front facade of the cleaning robot, and the charging contact is electrically connected to the battery.

[0036] A further solution of the cleaning robot of the present invention is to remove the intelligent control component that controls the walking of the cleaning robot, and to install a floor scrubber handle rod with a control switch on the rear end of the cleaning robot frame in a hinged manner, and to replace all the walking wheels with universal wheels, so that the cleaning robot is converted into a floor scrubber.

[0037] In a further embodiment of the cleaning robot of the present invention, the handle of the floor scrubber is a tubular structure, and the lower end of the handle rod of the floor scrubber is connected to the air outlet of the sewage tank through a suction hose;

[0038] The upper port of the handle rod of the floor scrubber is plugged into a handheld vacuum cleaner for suction, and the control switch of the floor scrubber is installed on the upper end of the handle rod of the floor scrubber.

[0039] The clean water tank and battery can also be relocated and installed at the lower part of the handle bar. Both are in the shape of a flat box, so that the handle bar can be laid flat to clean the low space under the sofa without increasing the height of the floor scrubber.

[0040] The utility model solves the above-mentioned technical problems of the existing cleaning robot equipped with a cleaning device by adopting a technical solution: a cleaning table is used in conjunction with the cleaning robot, and is used for the cleaning robot to dump garbage, discharge sewage, add clean water, charge, and clean the mopping brush. The cleaning table is square, and a funnel-shaped structure is formed inside the cleaning table body corresponding to the bottom of the garbage box. The funnel opening is larger than the bottom of the garbage box, so that all garbage dumped from the garbage box enters the funnel. A flushing pipe with flushing holes is provided on the upper edge of the funnel opening, and the flushing pipe is connected to the tap water pipe.

[0041] At the place corresponding to the sewage discharge port below the cleaning robot, a trumpet-shaped water receiving nozzle is provided in the cleaning table body. The lower end of the water receiving nozzle is connected to the funnel through a sewage pipe, so that the discharged sewage enters the funnel;

[0042] The flushing pipe can flush the garbage and sewage in the funnel downwards. The flushing pipe is equipped with a funnel flushing solenoid valve, which is controlled by the intelligent controller of the cleaning table. A garbage basket is provided at the lower end of the funnel. The garbage stays in the garbage basket, and the sewage enters the sewer through the sewage pipe.

[0043] One side of the cleaning table is provided with a ramp that allows the cleaning robot to climb onto the multifunctional cleaning table; the ramp has an anti-slip function; and side baffles are provided on both sides of the ramp to prevent the cleaning robot from falling.

[0044] A functional wall is located on one side opposite the ramp, and enclosure panels are located on the other two sides. Inside the functional wall are the smart controller for the washing station, a charger, and a water pipe. A door for installation and maintenance is located on the outer facade of the functional wall.

[0045] A soap liquid box is installed on the top surface of the functional wall and the enclosure wall, with a soap liquid filling port on the top surface and a soap liquid discharge pipe at the bottom of the soap liquid box;

[0046] A water filling nozzle is provided on the inner facade of the functional wall, which matches the water filling port on the cleaning robot's clean water tank. The rear end of the water filling nozzle is connected to the tap water pipe and the soap liquid pipe through a three-way pipe fitting inside the functional wall. The tap water pipe and the soap liquid pipe are respectively equipped with a clean water solenoid valve and a soap liquid valve. The clean water solenoid valve and the soap liquid valve are electrically connected to the intelligent controller of the washing table. After the cleaning robot climbs onto the washing table, the water filling nozzle is inserted into the clean water tank's loudspeaker filling port on the front facade of the cleaning robot. After the clean water tank is filled with water, a certain proportion of soap liquid is added.

[0047] The water level sensor contacts on the inner side of the functional wall are electrically connected to the washing station intelligent controller inside the functional wall at the rear, and are electrically connected to the water level sensor contacts on the front facade of the cleaning robot at the front. In this way, when the water in the clean water tank is full, the water level sensor closes the clean water solenoid valve in the functional wall through the washing station intelligent controller, and stops adding water to the clean water tank;

[0048] The charging contacts on the inner facade of the functional wall are electrically connected to the charger inside the functional wall, and then connected to the charging contacts on the front facade of the cleaning robot to charge the battery.

[0049] The cleaning table has a sloped surface that tilts toward the functional wall. The gravity of the cleaning robot as it descends allows the water level sensor and charging contacts to fit more securely.

[0050] After the cleaning robot climbs onto the cleaning table, it starts charging its battery;

[0051] At the same time, the cleaning brush is cleaned while adding water to the clean water tank. The cleaning station intelligent controller controls the cleaning process. After cleaning, the clean water tank pump and the mopping brush will automatically stop rotating. Add water to the clean water tank and continue cleaning. The process will stop automatically when the tank is full.

[0052] At the same time, the onboard intelligent controller on the cleaning robot activates the electric push rod on the trash box, causing the bottom plate of the trash box to flip down to dump the garbage; at the same time, the onboard intelligent controller also opens the sewage discharge solenoid valve of the sewage tank to discharge the sewage; the garbage and sewage all fall into the funnel of the cleaning table, the garbage remains in the net basket and is dumped, and the sewage is discharged into the sewer;

[0053] After the garbage and sewage are discharged, the intelligent controller of the washing table opens the solenoid valve of the flush pipe, and water starts to flush along the flush pipe at the upper edge of the funnel mouth, and finally the inside of the washing table is rinsed clean.

[0054] A further solution of the cleaning robot cleaning device of the present invention is to provide a faucet heater on the water pipe between the back of the water adding nozzle and the clean water solenoid valve and the soap valve, so that the clean water and soap coming out of the water adding nozzle are both hot water or hot soap with stronger cleaning ability.

[0055] According to a further solution of the cleaning device of the cleaning robot of the present invention, a disinfection lamp is provided on the cleaning table to disinfect the sweeping component and the mopping component below the cleaning robot.

[0056] A further solution of the cleaning robot cleaning device of the utility model is to install a grinder under the funnel of the cleaning table. The garbage and sewage coming down from the lower port of the funnel are directly fed into the inlet of the grinder. After the garbage is ground into pulp by the grinder, it is flushed into the sewer together with the sewage.

[0057] The grinder is controlled by an intelligent controller on the cleaning table. When the cleaning robot reaches the cleaning table, the grinder starts and stops automatically after the garbage is processed.

[0058] A further solution of the cleaning device of the cleaning robot of the present invention is that a synchronous pulley is provided at the lower end of the grinder shaft, and a grinder driving motor with a matching synchronous pulley is provided, so that its synchronous pulley is fixedly installed side by side with the grinder below, and then the two synchronous pulleys are connected with a synchronous belt for transmission. The motor is controlled by an intelligent controller of the cleaning table, which can minimize the height of the grinder, thereby reducing the height of the cleaning table.

[0059] A further solution of the cleaning device of the cleaning robot of the present invention is that a rotating shaft is provided at the upper end of the ramp plate, which is hinged to the edge of the washing table. After the cleaning robot climbs onto the washing table, the ramp plate is immediately flipped upwards, and the ramp plate is then used as an upper panel of the fence door to close the fence door. The ramp plate is both a path for the cleaning robot to crawl onto the washing table and a door panel of the fence door.

[0060] In a further solution of the cleaning device of the cleaning robot of the utility model, a torsion spring for assisting the turning up of the ramp plate is installed on the rotating shaft of the ramp plate;

[0061] A synchronous pulley is installed at one end of the ramp plate shaft, and a motor is installed under the cleaning table. The motor is equipped with a synchronous pulley that matches the shaft synchronous pulley. The synchronous belt is driven by the motor, and the up and down flipping of the ramp plate is achieved by the forward and reverse rotation of the motor.

[0062] A limit switch handle is provided on the rotating shaft of the ramp plate. At the corresponding position of the handle, there is an upward limit switch and a downward limit switch. When the ramp plate is flipped into place, the limit switch stops the motor from rotating.

[0063] A push button switch is installed on the wall, and the push button switch is electrically connected to the shaft drive motor. After the sweeping robot climbs onto the multi-functional cleaning table and reaches its position, the front facade of the sweeping robot presses the push button switch, and the motor starts to rotate, flipping the ramp upward to close the wall door.

[0064] The fence door is equipped with a smart door lock, which can prevent theft when the cleaning robot is used in public places;

[0065] When the robot vacuum leaves the cleaning table and returns to the ground, the robot vacuum moves backward, the button switch pops up, and the motor starts to rotate to flip the ramp down and place it on the ground, allowing the robot vacuum to get off the cleaning table;

[0066] The button switch is electrically connected to the intelligent controller of the washing station. When the button switch is pressed, the intelligent controller of the washing station is also started at the same time. The intelligent controller of the washing station then starts the electric push rod under the garbage box to dump the garbage; opens the sewage discharge solenoid valve to discharge sewage, opens the clean water solenoid valve to add water to the clean water tank; opens the soap liquid solenoid valve to add soap liquid; starts the grinder to start grinding the garbage; finally, opens the funnel flushing solenoid valve to flush the funnel inside the washing station.

[0067] According to a further solution of the cleaning device of the cleaning robot of the present invention, after the cleaning robot is converted into a floor scrubber, a slot for the handle rod of the floor scrubber is provided on the soap liquid tank, and the handle rod can be inserted into the slot after being erected.

[0068] Compared with the prior art, the above technical solution has the following beneficial effects:

[0069] 1. The mopping assembly utilizes two large, high-speed, counter-rotating mopping brushes. This significantly increases the mopping surface area and ensures even mopping compared to the two disc mops used by typical cleaning robots. The high-speed rotation of the two mopping brushes further enhances the mopping effect, allowing the average household to thoroughly clean their entire home in one go.

[0070] 2. Because the mopping brush utilizes a mesh-shaped tubular shaft, flushing is done from the center outward, providing a thorough and clean rinse while conserving water. This innovative structural design elevates core floor cleaning technology to a new level.

[0071] 3. The vacuum cleaner head is installed behind the trash can, which not only makes the sweeping unit clean the dust more thoroughly, but also enables the cleaning robot to clean carpeted floors. In this way, the cleaning robot can clean all types of floors, including carpets, tiles, and wooden floors.

[0072] 4. Due to the structure of setting a water suction squeegee head behind the mopping component, all the residual water on the ground is sucked into the sewage tank by the water suction squeegee head. The ground mopped by the cleaning robot is basically dry and no longer slippery, which completely avoids falls and injuries due to slippery ground.

[0073] 5. Because the mopping component is equipped with a floor-washing mopping roller brush and a water-absorbing scraper head, it can wash the floors of kitchens and bathrooms, which completely changes the problem that ordinary sweeping robots cannot clean kitchens and bathrooms. The cleaning robot has a full range of complete floor cleaning functions for the whole house, which will greatly accelerate the popularization and application of cleaning robots.

[0074] 6. Thanks to a fluid sensor located on the front of the robot and a squeegee and mopping brush installed in the mopping assembly, the robot can pivot when encountering liquid waste, with the squeegee in front, first sucking the waste into the wastewater tank with the squeegee, and then using the mopping brush to clean the floor. This unique and innovative design completely resolves the long-standing issue of robotic sweepers' inability to handle liquid waste, and represents a significant advancement in robotic sweeper technology.

[0075] 7. Due to the structure of setting a hot air drying device at the rear of the cleaning robot, the floor or carpet cleaned by the cleaning robot can be dried and can also disinfect and sterilize the floor.

[0076] 8. Due to the hinged structure between the bottom of the trash box and the back wall of the trash box, and the electric push rod installed at the end of the trash box, which is controlled by the intelligent controller, the bottom of the trash box can be automatically flipped downward, thereby achieving the ideal effect of the cleaning robot automatically dumping garbage.

[0077] 9. Due to the adoption of a sewage discharge solenoid valve set at the bottom of the sewage tank, the solenoid valve is controlled by an intelligent controller, so that the cleaning robot can automatically discharge sewage.

[0078] 10. Due to the adoption of a one-way valve on the water supply pipe of the clean water tank and a one-way valve at the water inlet of the sewage tank, the ideal effect is that the clean water and sewage inside will not overflow no matter how the cleaning robot moves and changes its posture.

[0079] 11. Due to the adoption of a structure in which a garbage grinder is installed at the sewage outlet of the cleaning table and the ground garbage and sewage are discharged directly into the sewer, it has been completely realized that the cleaning robot no longer needs to rely on manual labor to dump garbage and sewage and add clean water. All the tasks are completed by the cleaning robot alone, which has achieved significant beneficial effects and realized the beautiful ideal that people have always expected that ground hygiene no longer needs to be managed by humans.

[0080] 12. A flushing pipe with flushing holes is set around the upper edge of the funnel of the washing table. The solenoid valve on the flushing pipe is controlled by the intelligent controller of the washing table. The garbage and sewage in the funnel can be flushed down at any time, achieving the ideal effect of keeping the inside of the washing table clean and preventing mold.

[0081] 13. When the cleaning robot is transformed into a floor scrubber, the clean water tank, sewage tank, suction fan and battery are all installed on the head of the floor scrubber, and there is no component attached to the handle of the floor scrubber. This not only makes the handle of the floor scrubber lighter and more flexible, making it easier to clean the floor, but also because the size of the handle of the floor scrubber is reduced, it can reach into the small places under the furniture for cleaning.
