Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, specifically relating to a method, system, and cleaning station for reminding users to empty their wastewater tanks. Background Technology

[0002] A cleaning robot is an intelligent cleaning device that can automatically clean surfaces. Because cleaning robots can reduce the burden of housework for users, they are increasingly entering people's homes.

[0003] Cleaning robots are typically equipped with a cleaning station. When the cleaning robot needs to clean its cloths, it automatically returns to the cleaning station. The cleaning station is equipped with a cleaning tank, a clean water tank, and a wastewater tank. When the cleaning robot stops at the cleaning station, the station starts the cloth cleaning program. A clean water pump draws clean water from the clean water tank into the cleaning tank or sprays it directly onto the cleaning robot's cloths. After cleaning, a wastewater pump pumps the wastewater in the cleaning tank back into the wastewater tank for temporary storage.

[0004] Due to the fast pace of life, many users often forget to empty their wastewater tanks at home, causing wastewater to remain inside for extended periods, sometimes even fermenting and producing unpleasant odors. Users often only realize they need to clean the tank when they smell it, and the cleaning process inevitably involves contact with dirt, resulting in a poor user experience.

[0005] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Summary of the Invention

[0055] Example 1

[0056] This embodiment provides a method for reminding customers at a cleaning station to empty their wastewater tanks. This method is applied to cleaning stations that provide cleaning services for cleaning equipment (see [link to documentation]). Figure 3 The cleaning station shown is 200.

[0057] In specific implementation scenarios, cleaning equipment can be cleaning robots, such as robotic mopping or robotic vacuum and mopping robots. A cleaning robot is a device that autonomously cleans within a work area using artificial intelligence. It mainly consists of a body, a cleaning component located at the bottom of the body, and a drive motor that rotates during cleaning to wipe away dirt from the surface. Specifically, the cleaning component typically includes a mop and a mop tray for holding the mop. The mop tray is connected to the drive motor and rotates, which in turn rotates the mop to wipe the surface.

[0058] Please see Figure 3 As shown, the cleaning station 200 is typically equipped with a cleaning tank, a clean water tank, a wastewater tank 210, and a suction mechanism. The clean water tank stores clean water for cleaning and has an inlet for replenishing water to it. The suction mechanism includes a water replenishment mechanism and a return pumping mechanism. The water replenishment mechanism is located on the water replenishment path from the clean water tank to the cleaning tank, and is used to pump water from the clean water tank to the cleaning tank. The return pumping mechanism is located on the return path from the cleaning tank to the wastewater tank, and is used to pump wastewater from the cleaning tank back to the wastewater tank for temporary storage. Specifically, the water replenishment mechanism includes a clean water pump and a water replenishment motor that drives the clean water pump; the return pumping mechanism includes a wastewater pump and a return pumping motor that drives the wastewater pump. The cleaning station 200 also includes a controller 220 that controls the operation of the clean water pump and the wastewater pump.

[0059] When the cleaning robot docks at the cleaning station, its cleaning components are located inside or above the cleaning tank, allowing the cleaning station to clean these components. The cleaning process mainly involves adding water to the cleaning tank, cleaning the cleaning components, and then pumping the wastewater from the cleaning tank back to the wastewater tank.

[0060] Existing cleaning stations rely on users to actively identify whether wastewater needs to be dumped. Some stations are equipped with wastewater level detection devices to remind users to dump wastewater based on the water level in the tank. This reminder logic alerts users when the wastewater level in the tank is above a certain threshold, but there are still technical problems that arise when the wastewater level in the tank does not reach the set threshold, leading to prolonged storage and fermentation, resulting in foul odors.

[0061] As can be seen, since the wastewater tank is used to store wastewater generated after cleaning, bacteria will grow and even ferment, emitting an odor, if it is not emptied in time. To remind users to empty the wastewater tank and reduce the risk of fermentation and foul odor, the method for reminding users to empty the wastewater tank provided in this embodiment includes the following:

[0062] S10. Record the assembly time when the sewage tank is lifted and reassembled to the cleaning station;

[0063] S20. Starting from the assembly time, the cleaning operation start timer is activated; wherein, the cleaning operation includes the cleaning station cleaning the cleaning components of the cleaning robot;

[0064] S30. When the accumulated time exceeds a preset threshold, a reminder signal is issued to empty the sewage tank.

[0065] In a specific embodiment, the cleaning station includes a main body, to which a wastewater tank is detachably mounted. The cleaning station also includes an identification unit for identifying the separation and assembly of the wastewater tank from the main body. The identification unit may include identification electrodes; when the wastewater tank is assembled onto the main body, the identification electrodes are activated, thus the electrical signal from the activated electrodes can distinguish whether the wastewater tank is assembled onto the main body. The identification unit may also be a microswitch; when the wastewater tank is assembled onto the main body, the microswitch is triggered, and the trigger signal from the microswitch can identify whether the wastewater tank is assembled or lifted. The identification unit may also use other identification methods, such as Hall effect recognition, which will not be detailed here.

[0066] When the wastewater tank is detected to have been lifted and then reassembled into the cleaning station, it is considered that the wastewater tank has completed one emptying cycle. At this point, the wastewater tank reassembled into the cleaning station is considered to have been cleaned, and the reassembly time is recorded. From this reassembly time, each cleaning operation will generate a certain amount of wastewater, which will eventually be pumped into the wastewater tank. Therefore, a timer is started whenever a cleaning operation is running. When the accumulated time exceeds a preset threshold, a reminder signal is issued to empty the wastewater tank.

[0067] Each cleaning operation involves a complete set of procedures, including the cleaning station replenishing water to the cleaning tank, performing the cleaning, and pumping the wastewater back into the wastewater tank. Completing this entire process constitutes one cleaning operation. It's understandable that there may be multiple cleaning operations after the timer starts but before the reminder signal is issued, or there may be only one cleaning operation.

[0068] The aforementioned reminder signal can be sent to the user's mobile terminal; that is, the receiving end of the reminder signal is the user's mobile terminal. Specifically, the mobile terminal can be a mobile phone, laptop, tablet, smartwatch, or other similar device. The mobile terminal is typically carried by the user, allowing them to receive the reminder signal promptly and check and clean the wastewater tank in a timely manner. Specifically, the reminder signal can be delivered via voice, text message, or other methods. It can also be a pop-up notification or a broadcast reminder.

[0069] The method for reminding users to empty the sewage tank provided in this embodiment starts from the moment the sewage tank is assembled and responds to the start time of the cleaning operation. When the accumulated time exceeds a preset threshold, a reminder signal to empty the sewage tank is issued. Thus, the cleaning station can proactively remind users to empty the sewage tank, reducing the risk of the sewage tank fermenting and becoming smelly.

[0070] In a specific embodiment, the above step "the response cleaning operation start timing" includes:

[0071] Obtain the start time of starting the cleaning operation or the end time of completing the cleaning operation;

[0072] The timing is started from the start time or the end time.

[0073] The aforementioned "end time for completing the cleaning work" includes the following steps:

[0074] Record the moment when the sewage pump finishes pumping sewage; use the moment when the sewage pump finishes pumping sewage as the starting point for starting the timer.

[0075] The above-mentioned "obtaining the start time of initiating the cleaning operation" includes the following steps:

[0076] Record the moment when the water pump starts drawing clean water; the moment when the water pump starts drawing clean water is taken as the starting timer.

[0077] Specifically, the sewage pump is driven by a return pump motor, and the control board is electrically connected to the return pump motor to control its start and stop. The control board can send control signals to connect and disconnect the return pump motor from the power supply, with the moment the signal to disconnect the return pump motor from the power supply being sent as the moment the sewage pump finishes pumping sewage. Correspondingly, the moment the control board sends a control signal to start the water supply motor is the moment the clean water pump starts pumping clean water.

[0078] Of course, in another embodiment, the start time of the cleaning work and the end time of the cleaning work can be obtained at the same time. The timing can be started from either the start time or the end time, or a time between the two times can be selected to start timing.

[0079] In a specific embodiment, the above step "recording the assembly time of the sewage tank being lifted and reassembled into the cleaning station" further includes the following:

[0080] Acquire a first identification signal indicating that the sewage tank has been lifted, and record the moment when the first identification signal is acquired;

[0081] Starting from the moment the first identification signal is acquired, a second identification signal indicating that the sewage tank is assembled into the cleaning station is acquired, and the moment when the second identification signal is acquired is recorded as the assembly moment.

[0082] As described above, the main body is equipped with an identification unit that can identify the separation and assembly of the sewage tank from the main body. When the identification unit detects that the sewage tank is lifted, it sends out a first identification signal; when the sewage tank is assembled into the main body, it sends out a second identification signal. The moment when the second identification signal is received is the assembly moment of the sewage tank.

[0083] In an implementation scenario where the identification unit includes an identification electrode, when the identification electrode is detected to change from a conducting to a de-conducting state, it is considered that the sewage tank has been lifted, and at this time, the signal of the identification electrode is recorded as the first identification signal; when the identification electrode is detected to change from a de-conducting to a conducting state, it is considered that the sewage tank has been assembled, and at this time, the signal of the identification electrode is recorded as the second identification signal.

[0084] In some cases, the sewage tank may be accidentally lifted and then put down again. During this process, no sewage is dumped, but the identification unit detects the lifting and assembly of the sewage tank. If the assembly time of the sewage tank is recorded at this time and the timing of the ongoing reminder signal is stopped, it may lead to inaccurate reminder signals, which in turn may result in the risk of untimely sewage dumping reminders.

[0085] To address the above problems, in one embodiment, the method further includes:

[0086] Calculate the time interval between the acquisition of the first identification signal and the second identification signal;

[0087] When the time interval is greater than a preset interval, the moment when the second identification signal is obtained is recorded as the assembly moment.

[0088] The first identification signal indicates that the sewage tank has been lifted, and the second identification signal indicates that the sewage tank has been reassembled into the main body. Thus, if the time interval between lifting and reassembling the sewage tank is less than a preset interval, it is assumed that the sewage tank has not been emptied, and the previous timing continues. For example, if the time interval is less than 10 seconds, it can be considered insufficient for the sewage tank to be emptied, and the current timing continues. If the time interval is greater than the preset interval, it is assumed that the sewage tank has completed one emptying operation, and if cleaning work is required, the timing restarts.

[0089] Sometimes, even after a reminder signal is issued, users still fail to empty the wastewater tank in time. For example, the user may be away on a business trip, and no one may be home to empty it, or the user may have received a reminder signal but still failed to empty it promptly.

[0090] To reduce the risk of unpleasant odors from sewage fermentation in this situation, in one embodiment, the sewage tank is equipped with an ultraviolet sterilization device. When the time exceeds a preset threshold, the ultraviolet sterilization device is activated to inhibit sewage fermentation and prolong its fermentation time.

[0091] The method for reminding users to empty wastewater tanks at cleaning stations provided by this invention can automatically send reminder signals to clean the wastewater tanks, eliminating the need for users to actively identify the wastewater and solving the technical problem of wastewater tanks fermenting and becoming smelly due to users forgetting to empty them in time.

[0092] Example 2

[0093] Please see Figure 2 As shown, a system 100 for reminding users to empty wastewater tanks at cleaning stations includes:

[0094] Recording module 110 records the assembly time when the sewage tank is lifted and reassembled to the cleaning station;

[0095] The timing module 130 starts timing in response to the cleaning operation, starting from the assembly time; the cleaning operation includes the cleaning station cleaning the cleaning components of the cleaning robot.

[0096] The reminder module 150 sends a reminder signal to empty the sewage tank when the accumulated time exceeds a preset threshold.

[0097] In one embodiment, the recording module 110 can record the assembly time of the sewage tank being lifted and reassembled to the cleaning station in the following manner: acquiring a first identification signal of the sewage tank being lifted and recording the time when the first identification signal is acquired; starting from the time when the first identification signal is acquired, acquiring a second identification signal of the sewage tank being assembled to the main body and recording the time when the second identification signal is acquired as the assembly time.

[0098] Furthermore, the method also includes: calculating the time interval between acquiring the first identification signal and the second identification signal; and when the time interval is greater than a preset interval, recording the moment when the second identification signal is acquired as the assembly moment.

[0099] In one embodiment, the timing module 130 can respond to the start timing of the cleaning operation in the following manner: obtain the start time of starting the cleaning operation and / or the end time of completing the cleaning operation; and start the timing with the start time or the end time.

[0100] In one specific embodiment, obtaining the end time of completing the cleaning work includes: recording the time when the sewage pump finishes pumping sewage; and starting the timing from the time when the sewage pump finishes pumping sewage.

[0101] In one specific embodiment, obtaining the start time of starting the cleaning operation includes: recording the moment when the clean water pump starts to draw clean water; and using the moment when the clean water pump starts to draw clean water as the starting timer.

[0102] The system for reminding the cleaning station to empty the wastewater tank in this embodiment corresponds to the method for reminding the cleaning station to empty the wastewater tank described above. The functions of each module in the system for reminding the cleaning station to empty the wastewater tank in this embodiment are described in detail in the corresponding method embodiments, and will not be repeated here.

[0112] The identification unit can be an identification electrode. The identification electrode can also connect the wastewater tank to the main body's power supply. In a specific embodiment, the wastewater tank 210 is also equipped with an ultraviolet sterilization device. When the wastewater tank 210 is assembled onto the main body 230, the ultraviolet sterilization device is connected to the power supply of the cleaning station 200 via the identification electrode. When the accumulated time exceeds a preset threshold, the controller 220 activates the ultraviolet sterilization device to disinfect the wastewater, reducing the risk of fermentation and foul odor due to the user's failure to dispose of the wastewater in a timely manner.
