Description

TECHNICAL AREA

[0001] The present application relates to the field of cleaning technology, in particular a cleaning system. STATE OF THE ART

[0002] With the development of science and technology and the improvement of living standards, floor scrubbers, sweeping and mopping machines and other household cleaning equipment have become more and more popular, reducing the burden of human housework.

[0003] Using floor scrubbers as an example, the scrubber performs a self-cleaning action after completing a cleaning task and returning to its base. The cleaning process for the roller brushes typically involves two steps: hot water washing and hot drying. In the base of modern floor scrubbers, these two steps are each accomplished using two different sets of components. During the hot water washing phase, the water for the roller brush is heated by heating elements such as a PTC (Positive Temperature Coefficient) heating element, located beneath a groove in the base to hold the roller brush. In the hot drying phase, the air around the resistance wire is heated, and a blower is used to force the heated air through an air duct in the base onto the surface of the roller brush for drying.However, both of the above designs are complex, which not only makes assembly more difficult but also increases manufacturing costs. More importantly, the overall time for the self-cleaning process is long, the drying effect is uneven, and the bristles of the roller brush often swell up after the self-cleaning cycle is complete, leading to poor cleaning performance during subsequent cleanings and problems such as high inrush current. CONTENTS OF THE PRESENT USE SAMPLE

[0004] In light of this, embodiments of the present application provide a cleaning system.

[0005] According to a first aspect of the embodiments of the present application, a cleaning system is provided comprising a cleaning device and a base, wherein the cleaning device comprises a main body and a floor brush, wherein the floor brush is provided inside with a roller brush and a water distributor, and wherein the main body is provided with a suction device; wherein the base is provided with a cleaning groove for receiving the roller brush, wherein the base is provided inside with a heating device, wherein the heating device is located below the roller brush, wherein the cleaning system is configured with a drying mode, wherein the water distributor is configured to be in a closed state in the drying mode, wherein the heating device is configured to be in a heating state in the drying mode, and wherein the roller brush is configured to be in a rotating state and in contact with the heating device in the drying mode to iron the roller brush through the heating device. Optionally, the heating device includes an infrared heating device or a PTC heating device.

[0006] Optionally, the heating device is designed as an arc-shaped structure adapted to the shape of the roller brush.

[0007] Optionally, in drying mode, the roller brush is also configured to have a positive rotation in a final movement before stopping the rotation.

[0008] Optionally, the cleaning system can also be configured to control the heating device so that it stops the heating and keeps the roller brush rotating when the drying mode is complete.

[0009] Optionally, the cleaning system is configured to be controlled to enter a spin-drying mode before entering a drying mode, with the cleaning system controlling the heating device in a heating state during the spin-drying mode, and with the roller brush being in contact with the heating device so that the roller brush can be ironed by the heating device while being spun.

[0010] Optionally, the heating device is the infrared heating device, which includes an infrared transmitter and a transmission element located below the roller brush.

[0011] Optionally, the infrared heating device includes a reflective element, with the reflective element and the transmission element being located on opposite sides of the infrared transmitter.

[0012] Optionally, the infrared heating device also includes a heat dissipation element, wherein the heat dissipation element is provided in the base and is located below the reflection element to prevent the heating device from burning the base.

[0013] Optionally, the base is also equipped with a blower, the blower being configured to be activated in drying mode to blow heat away from the heat dissipation element in a direction facing the roller brush.

[0014] Optionally, the heat dissipation element comprises a heat dissipation base and at least one heat dissipation plate, wherein the heat dissipation plate is located on the heat dissipation base and faces an opening; wherein, if there is a plurality of heat dissipation plates, they are uniformly spaced apart along a longitudinal direction of the infrared sensor, the longitudinal direction of the infrared sensor running parallel to an axis of the roller brush.

[0015] Optionally, the infrared heating device also includes a mounting bracket, wherein the mounting bracket is connected to the base, the infrared transmitter and the heat dissipation base in such a way that both the infrared transmitter and the heat dissipation element are connected to the base via the mounting bracket.

[0016] Optionally, a surface of the reflection element on a side facing the infrared transmitter is a downwardly recessed, curved surface, with the curved surface and the transmission element together enclosing a chamber.

[0017] Optionally, the base is also provided with a shock-absorbing cushion, the shock-absorbing cushion being provided at a connection point between the transmission element and the reflection element.

[0018] A self-cleaning method is applied to the cleaning system of the present application, wherein the cleaning system comprises a cleaning device and a base, wherein the cleaning device comprises a main body and a floor brush, wherein the floor brush is provided inside with a roller brush and a water distributor, and wherein the main body is provided with a suction device; wherein the base is provided with a cleaning groove for receiving the roller brush, wherein the base is provided inside with an infrared heating device, wherein the infrared heating device comprises an infrared transmitter and a transmission element located below the roller brush;

[0019] The self-cleaning process includes the following: In response to the spin command, the cleaning device is controlled to enter spin mode;

[0020] During the spin cycle, the water distributor remains closed while the roller brush rotates; in addition, during the spin cycle, the infrared heating device operates in heating mode, with the roller brush in contact with the transmission element to allow simultaneous ironing of the roller brush by the transmission element during the spin cycle.

[0021] Modern floor scrubbers often perform a self-cleaning cycle after completing their cleaning tasks. Existing self-cleaning systems are typically time-consuming and frequently use PTC or heating wires to directly heat water for hot water cleaning. Higher-quality machines will incorporate a separate set of heating wires to generate hot air for drying; therefore, most floor scrubbers will utilize two heat sources for both water heating and drying.

[0022] Furthermore, the drying process relies primarily on a separate hot air drying procedure. During the spin cycle, the roller brush operates at high speeds. At this stage, hot air drying alone would result in indiscriminate water spray. Simultaneously, the hot air would severely fray the roller brush bristles. Consequently, the spin cycle effect is not optimal in the current state of the art and cannot significantly shorten the subsequent drying time. This is due to the uneven drying effect when the roller brush bristles are severely frayed. Additionally, because some bristles stand upright, the contact with components such as the roller brush cover increases, leading to a high inrush current.

[0023] The solution of the present application enables both a more compact structure and improved self-cleaning efficiency and impact, as will be explained in more detail below.

[0024] First, the present application uses a single heat source, namely an infrared heating device, throughout the entire water washing and drying phase. In particular, the present application achieves multifunctional self-cleaning without the need for multiple heating devices. The advantage lies in the simplified control logic for both drying and self-cleaning heating, eliminating the need for constant switching between different heating components. It should be noted that each heating component requires a significant inrush current and a considerable preheating time. By using a single heat source, these problems are completely avoided. This eliminates the switching and preheating time associated with multiple heat sources. Combined with the rapid heating capability of infrared devices, the overall efficiency of the self-cleaning process is significantly improved.

[0025] Secondly, the present application achieves higher cleaning efficiency through several structures and logical control. In particular, the infrared heating device is activated after the water washing process, i.e., during the spin cycle. It should be taken into account that only minimal amounts of water remain on the base during the spin cycle (since the wastewater is extracted after washing) and that the roller brush and the transmission element remain in contact.

[0026] Furthermore, the transmission element operates at a high temperature. Consequently, the roller brush can be ironed on the transmission element simultaneously during the spin cycle. The shapes of the transmission element and the roller brush are matched, as both are curved. This ironing effect of the transmission element allows the roller brush to dry faster while simultaneously ensuring it remains flatter.

[0027] Thirdly: Since the drying process begins during the spin cycle, the roller brush is dried simultaneously with the spin cycle.

[0028] In particular, since the spin cycle has already begun during the subsequent drying process, the following preheating and heating times are eliminated, allowing the drying phase to begin immediately. Furthermore, heating takes place during the spin cycle, resulting in moisture evaporation due to the temperature. Consequently, the solution of the present application significantly improves the overall efficiency of the self-cleaning process and enhances the self-cleaning effect by incorporating heating and ironing during the spin cycle.

[0029] Fourth: Conventional heating methods predominantly use hot air. Consequently, the power consumption of the fan is often considerable. In contrast, the present application primarily utilizes infrared heating, which operates more quietly and does not require special high-powered fans to facilitate drying. Therefore, the use of the aforementioned infrared heating method reduces the overall noise generated during the self-cleaning process, resulting in an essentially noiseless washing and drying function.

[0030] Optionally, the infrared heating device includes a heat dissipation element, the heat dissipation element being located below the infrared transmitter;

[0031] Optionally, the base also includes a blower, the blower being controlled to be activated in spin mode to blow heat away from the heat dissipation element in a direction facing the roller brush.

[0032] It is understood that the heat dissipation element of the present application serves to absorb excess light or heat emitted by the infrared transmitter and thus prevent other components of the base from being damaged by excessive heat. In particular, it deals primarily with the heat emitted below the infrared transmitter, and accordingly, a fan is provided. The fan can be a low-power fan that serves to dissipate the heat accumulated on the heat dissipation element and thus distribute the concentrated heat.

[0033] In other words, the heat dissipation element absorbs and concentrates the heat emitted by the infrared transmitter, which is then conducted by the fan to the heat dissipation element to achieve heat dissipation. Accordingly, the heat dissipation element can be dark in color, for example, black or gray.

[0034] Additionally, an air duct is integrated into the base. Heat from the heat dissipation element is dissipated by the blower, and the air duct outlet faces the roller brush. The coordinated interaction of the blower, the heat dissipation element, the infrared transmitter, and the air duct achieves multi-stage heating of the roller brush while simultaneously preventing the base from burning. Specifically, this design provides the roller brush with both direct heating from the infrared transmitter and hot air heating from the heat dissipation element. This single device thus implements multiple heating modes, offering more heating options and a superior heating effect compared to prior art.

[0035] Optionally, the cleaning device also includes a detection device, the self-cleaning procedure comprising the following: Controlling the cleaning device to perform a self-cleaning action before executing the spin cycle;

[0036] The self-cleaning process includes the following: Controlling the cleaning device in response to a self-cleaning command to enter an initial cleaning mode, wherein the initial cleaning mode includes a first cleaning phase and a second cleaning phase; Control in the first cleaning mode so that the infrared heating device is activated, the water distributor sprays water and the roller brush rotates; Controlling the detection device to assess dirt detection based on the condition of the roller brushes after completion of the first cleaning phase by the cleaning device and to proceed with the execution of the second cleaning phase; wherein the condition of the roller brushes includes a slightly dirty condition, a moderately dirty condition and a heavily dirty condition.

[0037] In the present application, the cleaning device responds directly to the self-cleaning command during the self-cleaning process and switches directly to the self-cleaning state based on this command. It is controlled to enter the first cleaning mode, which is divided into two phases. After the first cleaning phase is completed, a dirt detection action begins. This ensures that a cleaning device, such as a floor scrubber, can execute the self-cleaning action immediately. If the cleaning device were configured to first evaluate a self-cleaning command after it is received, the floor scrubber would inevitably require a response time before actually switching to self-cleaning mode. Excessively long response times increase the time between command reception and execution completion, significantly impacting the user experience.

[0038] In other words, this self-cleaning process always immediately performs the first cleaning mode, regardless of the selected cleaning mode. The first cleaning mode is configured to activate the infrared heating device, spray water from the water distributor, and rotate the roller brush. This ensures that heated water is used for heating during the first cleaning mode, allowing dirt to dissolve more quickly and easily in the initial self-cleaning phase. This facilitates preparation for the subsequent cleaning modes, which correspond to the different states of the roller brush.

[0039] Optionally, during the first cleaning phase, the water spraying by the water distributor is stopped as soon as the spray volume reaches 45 ml to 55 ml.

[0040] During the second cleaning phase, the water spraying by the water distributor is stopped as soon as the spray volume reaches 45 ml to 55 ml.

[0041] After the water spraying by the water distributor has ended during the first cleaning phase and before the water spraying begins during the second cleaning phase, the suction device is activated to perform a suction action.

[0042] Furthermore, the first cleaning mode is divided into two phases, with the water volume also divided into two phases to ensure that the water volume in each phase is controlled between 45 ml and 55 ml. For example, if the duration of the first cleaning phase is set to 6 seconds and a spray volume of 2 seconds is sufficient to meet the requirement, the water distributor will be controlled to stop spraying after 2 seconds. The purpose of controlling the water volume is as follows.

[0043] First, since this is the initial phase, the current level of soiling in the floor scrubber is still unknown. Controlling the water flow prevents waste. Because the infrared sensor has just been put into operation, it takes some time to reach the target temperature. Controlling the water flow ensures that the water quickly reaches a suitable temperature, for example, 60°C.

[0044] Secondly, since the first cleaning mode is divided into two phases, allocating a specific amount of water to each phase allows for multiple cleanings with a small amount of water, thus improving the cleaning effect without wasting water.

[0045] Optionally, the cleaning device is controlled so that it enters a spin cycle at the end of a first cleaning mode if the soiling condition of the roller brush is a slightly soiled state;

[0046] If the soiling condition of the roller brush is moderately soiled, the cleaning device is controlled so that after the end of the first cleaning mode it enters an immersion washing mode and after the execution of the immersion washing mode it enters a spin-drying mode;

[0047] The immersion wash mode includes the following: controlling the infrared heating device, the water distributor spraying water, and the roller brush rotating, with a spray volume between 70 ml and 90 ml.

[0048] The above solution introduces a cleaning method for slightly soiled and moderately soiled conditions. If slightly soiled, the roller brush can be cleaned after just two hot water cleaning cycles in the first cleaning mode. This eliminates the need to waste resources or time on further cleaning, thus further controlling the self-cleaning time and preventing resource waste.

[0049] If a moderately soiled condition is detected after the two hot water cleaning phases in the first cleaning mode have been completed, the immersion wash mode is initiated. The immersion wash mode is configured with a larger spray volume, and the water volume is controlled to be between 70 ml and 90 ml to ensure that the brush bristles in contact with the floor are fully immersed, while the infrared heating element remains activated. In other words, the two hot water cleaning phases of the first cleaning mode and the self-cleaning function of the immersion wash mode are used in moderately soiled conditions to further enhance the cleaning effect of the brush.

[0050] Optionally, the cleaning device is controlled so that at the end of a first cleaning mode it enters a cleaning mode for heavy soiling if the soiling condition of the roller brush is heavily soiled;

[0051] The cleaning mode for heavy soiling includes the following: The infrared heating device is activated, the water distributor sprays water, and the roller brush rotates, with a spray volume between 50 ml and 70 ml. The water temperature in the cleaning groove is controlled between 90°C and 100°C. If heavy soiling is detected, after completing the two hot water self-cleaning phases of the first cleaning mode, the system switches to high-temperature self-cleaning. At this point, the spray volume is controlled to be between 50 ml and 70 ml to ensure that the aforementioned water volume can be heated quickly to 90°C to 100°C. This allows for a higher temperature and a larger volume of water to achieve high-temperature cleaning and soil dissolution, thus ensuring the aforementioned cleaning effect of the roller brush.

[0052] In other words, the present application represents an intelligent cleaning method. By directly entering the first cleaning mode, which is divided into two phases, and assessing the condition of the roller brush during the second phase to determine the next cleaning action, both the rapid realization of self-cleaning and the effectiveness of the self-cleaning effect are ensured through intelligent assessment, thus achieving maximum cleaning efficiency. Simultaneously, the infrared heating device undergoes all phases of self-cleaning, further guaranteeing the cleaning effect.

[0053] A self-cleaning method is applied to the cleaning system of the present application, wherein the cleaning system comprises a cleaning device and a base, wherein the cleaning device comprises a main body and a floor brush, wherein the floor brush is provided inside with a roller brush and a water distributor, and wherein the main body is provided with a suction device; wherein the base is provided with a cleaning groove for receiving the roller brush, wherein the base is provided inside with an infrared heating device, the infrared heating device comprising an infrared transmitter and a transmission element located below the roller brush; wherein the self-cleaning method comprises the following: Controlling the cleaning device in response to a drying command to enter a drying mode; wherein the water distributor is in a closed state in the drying mode, the roller brush is rotating, and the infrared heating device is in a heating state; Controlling the infrared heating device to stop the heating when the drying mode is finished; Control the roller brush so that it remains in a rotating state for a predetermined time after the infrared heating device stops heating.

[0054] The present application provides an infrared heating solution in which the infrared heating device goes through the entire process of cleaning the roller brush, including the self-cleaning process as well as the spin-drying and drying phases; i.e., a single heating device is used to meet the heating requirements of the different phases while ensuring maximum drying efficiency and saving energy.

[0055] In the drying phase described above, the infrared heating device is controlled directly so that the heating is stopped after a certain time, but at this point the temperature on the transmission element is still high. This residual temperature can then be used for further drying. In other words, with the prior art, the heating device often needs to be switched on for 30 minutes to achieve the effect of high-temperature drying. With this solution, the infrared heating device only needs to be switched on for 25 minutes, and then the residual temperature can be used to complete the heating and drying process.

[0056] During residual heat heating, the roller brush rotates, and the brush bristles and the transmission element are in contact. This residual heat creates an ironing effect, ensuring that the brush bristles are flattened at the end of the drying process. Simultaneously, the rotation of the roller brush prevents the bristles from being held at an angle, which would otherwise lead to bristle burn.

[0057] Optionally, controlling the roller brush in a rotational state includes the following: controlling the roller brush to rotate alternately forwards and backwards.

[0058] Reversing the rotation of the roller brush allows the bristles to point upwards, facilitating heat transfer into the brush's interior and improving drying efficiency. Forward rotation flattens the bristles by utilizing the contact between the brush and the transmission element, ensuring a flatter brush head. Therefore, alternating forward and reverse rotation improves drying efficiency and effectiveness while reducing the risk of brush burnout. Additionally, the final forward rotation before stopping can be configured to soften the bristles and ensure a flatter brush head.

[0059] Optionally, the infrared heating device further comprises a heat dissipation element and a reflection element, wherein the reflection element and the transmission element are located in a vertical direction on opposite sides of the infrared emitter, with the heat dissipation element being located below the reflection element.

[0060] The function of the heat dissipation element is as described above and is not repeated. Optionally, the base further comprises a blower, a ventilation hole located on the circumferential side of the roller brush, and an air duct located between an outlet of the blower and the ventilation hole, wherein at least the infrared transmitter and the heat dissipation element are located within the air duct;

[0061] In drying mode, the blower is controlled to be switched on, and the airflow blown by the blower can flow through the air duct to the ventilation hole to blow heat from the infrared transmitter and the heat dissipation element in a direction facing the roller brush.

[0062] The ventilation hole is the outlet of the air duct in the base; the ventilation hole faces the roller brush; the wind blown by the blower flows through the air duct to the ventilation hole and is then blown through the ventilation hole to the roller brush, so that the blower, the heat dissipation element, the infrared transmitter, the air duct, etc., work together to achieve multiple heating of the roller brush and to ensure that the base is not burned.

[0063] Optionally, the reflection element and the transmission element together enclose a chamber, wherein the infrared transmitter is located in the chamber, the reflection element having an opening on its underside that is connected to the chamber, and the heat dissipation element being opposite the opening.

[0064] The chamber can better concentrate the heat generated by the infrared emitter onto the roller brush. For example, the surface of one side of the reflective element forming the chamber is a downward-facing curved surface. This curved surface allows the reflected infrared rays to be collected and projected centrally onto the roller brush. In this way, the loss of infrared rays outside the chamber is reduced, and the utilization rate of the infrared rays emitted by the infrared emitter is improved. The opening can reduce the barrier between the infrared emitter and the heat dissipation element, allowing the heat within the chamber to be transferred to the heat dissipation element more quickly and thus improving the heat dissipation effect.

[0065] Optionally, the heat dissipation element comprises a heat dissipation base and at least one heat dissipation plate, wherein the heat dissipation plate is located on the heat dissipation base and faces an opening; wherein there are multiple heat dissipation plates, the multiple heat dissipation plates being evenly spaced apart along a longitudinal direction of the infrared sensor, the longitudinal direction of the infrared sensor running parallel to an axis of the roller brush.

[0066] The heat dissipation base can either increase the heat dissipation area or serve as a mounting platform for the heat dissipation plate. The greater the number of heat dissipation plates, the larger the heat-emitting surface and the more advantageous it is to improve the heat dissipation effect.

[0067] The multiple heat dissipation plates are evenly spaced along the length of the infrared transmitter, so that heat can be dissipated from all points of the infrared transmitter 220 via the heat dissipation plates to further improve the heat dissipation effect.

[0068] Optionally, the infrared heating device also includes a mounting bracket, wherein the mounting bracket is connected to the base, the infrared transmitter and the base in such a way that both the infrared transmitter and the heat dissipation element are connected to the base via the mounting bracket.

[0069] The mounting bracket can confine and secure the infrared transmitter, effectively improving the reliability and strength of the connection between the transmitter and the base. It also effectively reduces or prevents wobbling of the transmitter, which can damage it, thus improving the protection of the transmitter and extending its lifespan.

[0070] Furthermore, using the mounting bracket to simultaneously install the infrared transmitter and the heat dissipation element improves the utilization rate of the mounting bracket, which helps to save space in the base.

[0071] Optionally, a surface of the reflection element on a side facing the infrared transmitter is a downwardly recessed, curved surface, with the curved surface and the transmission element together enclosing a chamber.

[0072] Optionally, the infrared heating device also includes a shock-absorbing pad located at a connection point between the transmission element and the reflection element.

[0073] The shock-absorbing pad can absorb the vibrations generated during the self-cleaning process, thus reducing or even preventing damage to the infrared heating device due to vibrations caused by the rotation of the roller brush, taking the cleaning device off and putting it down from the base, and the like.

[0074] A self-cleaning method is applied to the cleaning system of the present application, wherein the cleaning system comprises a cleaning device and a base, wherein the cleaning device comprises a main body and a floor brush, wherein the floor brush is provided inside with a roller brush and a water distributor, and wherein the main body is provided with a suction device; wherein the base is provided with a cleaning groove for receiving the roller brush, wherein the base is provided internally with a detection device and an infrared heating device, wherein the infrared heating device comprises an infrared transmitter and a transmission element located below the roller brush; wherein the self-cleaning method comprises the following: Controlling the cleaning device in response to a self-cleaning command to switch to an initial cleaning mode, wherein the initial cleaning mode comprises a first cleaning phase and a second cleaning phase; controlling the device in the initial cleaning mode to activate the infrared heating device, spray water from the water distributor, and rotate the roller brush; Controlling the detection device to assess dirt detection based on the condition of the roller brushes after completion of the first cleaning phase by the cleaning device and to proceed with the execution of the second cleaning phase; wherein the condition of the roller brushes includes a slightly dirty condition, a moderately dirty condition and a heavily dirty condition.

[0075] In the present application, the cleaning device responds directly to the self-cleaning command during the self-cleaning process and switches directly to the self-cleaning state based on this command. It is controlled to enter the first cleaning mode, which is divided into two phases. After the first cleaning phase is completed, a dirt detection action begins. This ensures that a cleaning device, such as a floor scrubber, can execute the self-cleaning action immediately. If the cleaning device were configured to first evaluate a self-cleaning command after it is received, the floor scrubber would inevitably require a response time before actually switching to self-cleaning mode. Excessively long response times increase the time between command reception and execution completion, significantly impacting the user experience.

[0076] In other words, this self-cleaning process always immediately performs the first cleaning mode, regardless of the selected cleaning mode. The first cleaning mode is configured to activate the infrared heating device, spray water from the water distributor, and rotate the roller brush. This ensures that heated water is used for heating during the first cleaning mode, allowing dirt to dissolve more quickly and easily in the initial self-cleaning phase. This facilitates preparation for the subsequent cleaning modes, which correspond to the different states of the roller brush.

[0077] Optionally, the self-cleaning procedure before entering the first cleaning mode also includes the following: Performing a blockage test on the roller brush, wherein the blockage test comprises controlling the roller brush to rotate alternately forwards and backwards, wherein the backward rotation angle of the roller brush is less than 360°.

[0078] The blockage test immediately determines whether the roller brush is blocked, protects the roller brush motor from overcurrent, and ensures the safety of the operating process.

[0079] During reverse rotation, a reverse rotation angle of less than 360° for the roller brush reduces tangling and other debris ejected from the front of the brush. This allows the debris to be more effectively directed to a dirt suction opening in the floor brush and then collected under the effect of negative pressure. This further improves the cleaning effect of the dirt on the roller brush.

[0080] The alternating forward and reverse rotation of the roller brush also contributes to further improving the cleaning effect on the tangles. For example, when the roller brush motor drives the cleaning element to a forward rotation, the scraper strip on the bottom brush can be used to collect and cut the tangles, and the reverse rotation of the roller brush can loosen the tangles that have become lodged on the roller brush. Once the tangles are freed, the roller brush can be rotated forward again so that the scraper strip can collect and cut the tangles once more, thus allowing the tangles to be cleaned by the alternating forward and reverse rotation during the blockage test.

[0081] Optionally, the reverse rotation angle of the roller brush is 280° to 340°, wherein a starting point of the reverse rotation angle is a contact point between the roller brush and the transmission element, with a vertical line between the contact point and the axis of the roller brush running perpendicular to the horizontal plane.

[0082] The reverse rotation angle of the roller brush from 280° to 340° can better prevent the dirt from being ejected from the front of the roller brush, and the dirt can be brought to the dirt suction opening of the floor brush more frequently.

[0083] In particular, most of the dirt in conventional machines is located in the roller brush cover, water distributor, scraper strip, etc., and by using reverse rotation, the dirt in these areas can be cleaned more effectively. The contact position between the roller brush and the base is defined as the starting point, and then the reverse rotation angle of the roller brush is set to 280° to 340° to ensure that the roller brush can be cleaned up to the aforementioned position by rotating backward. In other words, controlling the reverse rotation angle of 280° ensures that the roller brush can be cleaned at least up to the positions including the roller brush cover to achieve the aforementioned dirt removal.The 340° setting ensures that the dirt above is definitely not ejected by the roller brush drive, and at the same time it can move the dirt into the dirt suction position above, which not only ensures the cleaning effect but also prevents the dirt from appearing in other positions.

[0084] The roller brush blockage test optionally includes the following: Controlling the motor of the roller brush to rotate the roller brush forward for a first predetermined time, then controlling the motor of the roller brush to rotate the roller brush backward for a second predetermined time;

[0085] Determining a blockage of the roller brush rotation in response to a current in the roller brush motor being greater than or equal to a first current value during the forward rotation of the roller brush, and / or in response to a current in the roller brush motor being greater than or equal to a second current value during the reverse rotation of the roller brush; wherein the second current value is greater than the first current value.

[0086] The blockage test immediately determines whether the roller brush is blocked, protects the roller brush motor from overcurrent, and ensures the safety of the operating process.

[0087] Optionally, the self-cleaning process also includes the following: Controlling the cleaning device so that it enters a spin cycle at the end of a first cleaning mode if the soiling condition of the roller brush is a slightly soiled state; Controlling the cleaning device to enter a second cleaning mode when the roller brush condition is moderately dirty or heavily dirty, in the event that the second cleaning phase is completed; wherein the temperature of the cleaning water in the second cleaning mode, when the roller brush condition is moderately dirty, is lower than the temperature of the cleaning water in the second cleaning mode, when the roller brush condition is heavily dirty.

[0088] The above solution introduces a cleaning method for lightly soiled, moderately soiled, and heavily soiled conditions. If light soiling is detected, the current roller brush can be cleaned and moved to the spin cycle after just two hot water cleaning cycles in the first cleaning mode. This eliminates the need to waste resources or time on further cleaning, thus further controlling the self-cleaning time and preventing resource waste.

[0089] If a moderately or heavily soiled condition is detected after the two hot water cleaning phases of the first cleaning mode have been completed, the second cleaning mode is initiated. The second cleaning mode is configured with a higher spray volume and / or a higher water temperature, while the infrared heating element remains activated. This means that the two hot water cleaning phases of the first cleaning mode and the self-cleaning function of the second cleaning mode are utilized in moderately or heavily soiled conditions to further ensure the cleaning effect of the roller brush.

[0090] Optionally, the procedure also includes the following: In the second cleaning mode, the temperature of the cleaning water is controlled by providing different amounts of water, with the amount of cleaning water being negatively correlated with the temperature of the cleaning water.

[0091] If the other conditions are the same or nearly the same (e.g., the infrared transmitter's power is unchanged, the heating time is the same or not very different), the larger the volume of cleaning water, the lower the water temperature; conversely, the smaller the volume of cleaning water, the higher the water temperature. Water volume and water temperature are negatively correlated. By controlling the water volume, the water temperature can be controlled more easily and conveniently.

[0092] Optionally, the second cleaning mode includes an immersion wash mode. If the roller brush is moderately dirty, the cleaning unit is controlled to enter an immersion wash mode after the first cleaning mode has finished, and then to enter a spin-dry mode after the immersion wash mode has completed.

[0093] The immersion wash mode includes the following: controlling the infrared heating device, the water distributor spraying water, and the roller brush rotating, with a spray volume between 70 ml and 90 ml.

[0094] The beneficial effects of immersion washing are described in the previous description and are not repeated here.

[0095] Optionally, the second cleaning mode includes a cleaning mode for heavy soiling;

[0096] Controlling the cleaning device so that at the end of a first cleaning mode it enters a heavy soiling cleaning mode if the soiling condition of the roller brush is heavily soiled;

[0097] The cleaning mode for heavy soiling includes the following: controlling the infrared heating device, the water distributor spraying water, the roller brush rotating, with the spray quantity between 50 ml and 70 ml, and with the water temperature in the cleaning groove being controlled between 90°C and 100°C.

[0098] The beneficial effects of the cleaning mode for heavy soiling are described in the previous description and are not repeated here.

[0099] Optionally, during the first cleaning phase, the water spraying by the water distributor is stopped as soon as the spray volume reaches 45 ml to 55 ml.

[0100] During the second cleaning phase, the water spraying by the water distributor is stopped as soon as the spray volume reaches 45 ml to 55 ml.

[0101] After the water spraying by the water distributor has finished during the first cleaning phase and before the water spraying begins during the second cleaning phase, the suction device is activated to perform a suction action. The beneficial effects are described in the previous description and are not repeated here. Optionally, the self-cleaning process also includes the following: Controlling the infrared heating device to stop the heating when the drying mode is finished; Controlling the roller brush so that it remains in a rotating state for a predetermined time after the infrared heating device stops heating. The beneficial effects are described in the previous description and are not repeated here.

[0102] Optionally, the base further comprises a temperature detector, wherein the reflection element and the transmission element together enclose a chamber, with both the infrared transmitter and the temperature detector located in the chamber; wherein the infrared transmitter of the temperature detector is used to detect the temperature of the air near the infrared transmitter.

[0103] The temperature detector detects the lower air temperature, rather than directly measuring the higher temperature of the infrared transmitter or transmission element, which helps to reduce damage to the temperature detector.

[0104] Optionally, the self-cleaning process also includes the following: Controlling the operating parameters of the infrared transmitter so that the temperature detector recognizes a temperature from 90°C to 120°C.

[0105] If the temperature is below 90°C, the temperature of the transmission element makes it difficult to heat the liquid on it to a higher temperature (e.g., 100°C). A temperature that is too high, e.g., above 120°C, leads to an excessive temperature rise, resulting in the formation of too much steam and too little water. Conversely, a temperature between 90°C and 120°C ensures that the correct amount of water remains on the transmission element during the washing phase and that the correct amount of steam is generated. In other words, within this temperature range, it is possible to dissolve the dirt at a high temperature, obtain a specific amount of water to achieve an immersion effect, and utilize the high temperature of the steam for sterilization, thus effectively improving the washing effect during the washing phase.

[0106] The cleaning system in the embodiments of the present application further comprises a control unit. The control unit serves to carry out the self-cleaning process described above. The cleaning system in the embodiments of the present application has the same technical effect as the self-cleaning process described above, and the description is not repeated here.

The accompanying drawings are not necessarily to scale; local features may be enlarged or reduced to illustrate details of these features more clearly. Unless otherwise defined, the technical and scientific terms used herein have the same meaning as in the relevant technical field of the present application.

Provided there is no conflict, each step within an embodiment may be implemented as an independent embodiment, and the steps may be combined in any way. For example, a solution in which certain steps from an embodiment are omitted may be implemented as an independent embodiment; the order of the steps within an embodiment may be freely interchanged; and optional implementations within an embodiment may be freely combined. Furthermore, embodiments may be combined in any way.For example, partial or complete steps from different embodiments can be combined as desired, and an embodiment can be combined as desired with optional implementations from other embodiments.

[0110] In the embodiments of the present application, unless otherwise specified or logically contradictory, the terminology and / or descriptions are consistent across all embodiments and may be cross-referenced. Technical features from different embodiments may be combined to form new embodiments based on their inherent logical relationships.

[0111] The terminology used in the embodiments of the present application serves solely to describe specific embodiments and is not to be understood as limiting the scope of the present application. Example 1

[0112] The exemplary embodiment provides a cleaning system. Referring to the following... Fig. The cleaning system is described in detail in sections 1 to 7.

[0113] As in Fig. As shown in Figures 1 to 3, the cleaning system 10 comprises a cleaning device 100 and a base 200. The cleaning device 100 may include a floor brush. During operation, the cleaning device 100 moves over the surface to be cleaned and cleans this surface by frictional contact between the floor brush and the surface. With reference to Fig. 1. The floor brush 100 can comprise a housing, a roller brush 110, an impeller 102, and a water distributor. The housing serves as a support structure for the main body of the floor brush 100, and both the roller brush 110 and the impeller 102 can be mounted in the housing 103. For example, the housing 103 can have a receiving cavity, wherein the roller brush 110 can be located in the receiving cavity of the housing 103, and the roller brush 110 can rotate about its own axis.

[0114] During the cleaning process, the roller brush 110 is in contact with the surface to be cleaned. Driven by its integrated motor, the roller brush 110 rotates at high speed, creating frictional contact between the brush and the surface. The wheel 102 is also in contact with the surface and rolls along it, assisting the cleaning device as it moves across the surface and improving the stability of the floor brush 100 as it moves.

[0115] As in the Fig. 2 and Fig. As shown in Figure 3, the base 200 is provided with a cleaning groove 211, which serves to receive the roller brush 110 of the cleaning device 100. When the cleaning device 100 is placed on the base 200, it performs a self-cleaning process. During this process, the roller brush 110 is washed and dried in the cleaning groove 211.

[0116] The cleaning system further includes a heating device located within the base 200. The heating device can be designed as an arc-shaped structure adapted to the shape of the roller brush. The heating device can be an infrared heater or a PTC heater. As shown in the Fig. As shown in Figures 4 to 6, the infrared heating device comprises a transmission element 230 and an infrared transmitter 220, wherein both the transmission element 230 and the infrared transmitter 220 are located below the roller brush 110, and wherein the transmission element 230 can be in contact with the roller brush 110.

[0117] The transmission element 230 can allow infrared rays to pass through. The infrared transmitter 220 can emit infrared rays, and at least some of the infrared heat emitted by the infrared transmitter 220 can be radiated to the roller brush 110 via the transmission element 230.

[0118] When the infrared transmitter 220 is switched on, a higher temperature can build up on the transmission element 230 and the transmission element 230 can iron the roller brush 110 by contact with the roller brush 110, thereby further improving the drying efficiency and making the bristles smoother.

[0119] In one embodiment, the transmission element 230 can be a glass plate whose back side has a temperature of 200 °C to 280 °C, so that the temperature it can reach is higher than the temperature of the hot air or the ordinary heating method according to the prior art, and it can use the high temperature to interact with the roller brush and achieve ironing and drying.

[0120] The infrared rays generated by the infrared transmitter 220 can quickly penetrate the transmission element 230 and the surface of the material of the roller brush 110, transferring the energy directly to the interior and surface of the roller brush 110, thereby effectively accelerating the drying speed of the roller brush 110 and improving the drying efficiency of the roller brush 110.

[0121] Furthermore, the infrared rays can ensure a uniform heat distribution, thereby effectively reducing or preventing local overheating or failure of the roller brush 110 to dry, and thus significantly improving drying quality. Moreover, in the embodiments of the present application, the infrared transmitter 220 can transfer heat directly to the surface and interior of the roller brush 110 compared to conventional hot air drying, and the heat conduction loss is lower, resulting in better energy savings.

[0122] In some optional embodiments, the transmission element 230 can form at least part of the underside of the cleaning groove 211.

[0123] For example, the transmission element 230 can be connected to the base 200, and in the vertical direction (a direction that is essentially perpendicular to the horizontal plane) the transmission element 230 can be located between the infrared transmitter and the roller brush 110, and the roller brush can be kept in contact with the transmission element 230 during rolling.

[0124] In some optional embodiments, such as in Fig. As shown in Figure 5, the base 200 can have a receiving space 213 in which the infrared heating device is at least partially located. For example, both the infrared transmitter 220 and the blower 250, etc., can be located in the receiving space 213 so that the base 200 can mount and secure the above components. The receiving space 213 can be specifically formed by defining a base shell 210.

[0125] In some optional embodiments, the infrared transmitter 220 can be a carbon fiber heating tube. When the infrared transmitter 220 is switched on, an electric current can be supplied to the carbon fiber heating tube. The current flows through the carbon fiber heating tube and sets the molecules within the carbon fiber heating tube in motion, thereby converting the electrical energy into heat energy. The heat energy can be emitted quickly and uniformly around the roller brush 110 in the form of infrared radiation to dry the roller brush 110.

[0126] In some optional embodiments, the wavelength band of the infrared rays can be between 1.5 µm and 15 µm, the light in this wavelength band can be effectively absorbed by the organic matter and the intensity of the infrared radiation can be increased by more than 30%, resulting in a strong infrared radiation effect.

[0127] The transmission element 230 can isolate the infrared transmitter 220 and the roller brush 110 from each other and reduce or avoid direct contact between the roller brush 110 and the infrared transmitter 220, and also prevent water stains, dirt, etc. on the roller brush 110 from contaminating the infrared transmitter 220, and reduce the risk of damage to the infrared transmitter 220 due to contamination by water stains or dirt, and improve the protection of the infrared transmitter 220.

[0128] For example, the transmission element 230 can be a glass plate or a translucent plastic plate.

[0129] The transmission element 230 can, for example, have the shape of a convex lens, and this convex, lens-shaped transmission element 230 can collect the transmitted light so that the infrared rays passing through the transmission element 230 are concentrated in such a way that they are projected centrally onto the roller brush 110. In this way, the amount of infrared rays projected onto the roller brush 110 can be effectively increased and the waste of infrared rays reduced, thereby effectively improving the utilization rate of the infrared rays and increasing the drying efficiency of the infrared heating device on the roller brush 110.

[0130] In some optional embodiments, such as in Fig. As shown in Figures 4 to 6, the infrared heating device can further comprise a reflective element 240, wherein the reflective element 240 and the transmission element 230 are located on opposite sides of the infrared emitter 220 in the vertical direction. Optionally, the heat dissipation element 290 is located in the base and below the reflective element 240 to prevent the heating device from burning the base. At least a portion of the infrared rays can be reflected by the reflective element 240 onto the transmission element 230 and emitted by the transmission element 230 onto the roller brush 110. For example, the surface of the reflective element 240 facing the infrared emitter 220 can have a mirror surface, so that the infrared rays projected onto the mirror surface of the reflective element 240 can be reflected.

[0131] For example, the infrared rays generated by the surface of the infrared transmitter 220 facing the roller brush 110 can be projected onto the transmission element 230 and through the transmission element onto the roller brush 110. Conversely, the infrared rays generated by the surface of the infrared transmitter 220 facing the roller brush 110 can be projected onto the reflection element 240 and reflected by the reflection element 240 onto the transmission element 230, and thus projected through the transmission element 230 onto the roller brush 110 to dry the roller brush 110.

[0132] By reflecting the infrared rays through the reflective element 240, the infrared rays generated by the infrared transmitter 220 on the surface facing the roller brush 110 can also be projected onto the roller brush 110 to dry it. This effectively increases the amount of infrared rays projected onto the roller brush 110, thereby reducing or eliminating wasted infrared radiation. As a result, the utilization rate of the infrared rays is effectively improved, and the cleaning and drying efficiency of the roller brush 110 is enhanced by the base 200.

[0133] In some optional embodiments, the infrared heating device further comprises a heat dissipation element 290, wherein the heat dissipation element 290 is located below the infrared transmitter 220. The heat dissipation element 290 can absorb some of the energy from the infrared transmitter 220, reducing the temperature in the vicinity of the infrared transmitter 220, thereby effectively ensuring the service life of the base components and avoiding the potential risks caused by excessive heat concentration.

[0134] For example, the length of the heat dissipation element 290 and the length of the infrared transmitter 220 can also be approximately the same in order to improve the heat dissipation effect at different points on the infrared transmitter 220. To further improve the heat dissipation effect, the heat dissipation element 290 optionally includes several heat dissipation plates 291, as shown in Fig. Figure 7 shows the multiple heat dissipation plates 291 being evenly spaced apart from each other along the longitudinal direction of the infrared transmitter 220.

[0135] In some optional embodiments, the reflection element 240 and the transmission element 230 together enclose a chamber 241, wherein the infrared transmitter 220 is located in the chamber 241; wherein the reflection element 240 has an opening 242 on its underside, which is connected to the chamber 241, and wherein the heat dissipation element 290 is located opposite the opening 242.

[0136] The chamber can better concentrate the heat generated by the infrared transmitter onto the roller brush. For example, the surface of one side of the reflective element forming the chamber is a downward-facing curved surface (see especially below), and this curved surface allows the reflected infrared rays to be collected and projected centrally onto the roller brush 110. In this way, the loss of infrared rays outside the chamber is reduced, and the utilization rate of the infrared rays emitted by the infrared transmitter is improved.

[0137] The opening 242 can reduce the barrier between the infrared transmitter 220 and the heat dissipation element 290, allowing heat in chamber 241 to be transferred more quickly to the heat dissipation element 290 and thus improving the heat dissipation effect. In some optional embodiments, the heat dissipation element 290 comprises a heat dissipation base 292 and at least one heat dissipation plate 291, the heat dissipation plate 291 being located on the heat dissipation base 292 and opposite the opening 242. The heat generated by the infrared transmitter 220 can be transferred through the opening 242 to the heat dissipation plate 291 and also to the heat dissipation base 292 to improve the heat dissipation effect.

[0138] The heat dissipation base 292 can either increase the heat dissipation area or serve as a mounting bracket for the heat dissipation plate 291. The greater the number of heat dissipation plates 291, the larger the heat dissipation area and the more advantageous it is to improve the heat dissipation effect.

[0139] The heat dissipation base 292 can either increase the heat dissipation area or serve as a mounting bracket for the heat dissipation plate 291. The greater the number of heat dissipation plates 291, the larger the heat dissipation area and the more advantageous it is to improve the heat dissipation effect.

[0140] Several heat dissipation plates 291 are evenly spaced along the length of the infrared transmitter 220, the length of which is parallel to the axis of the roller brush 110. In this way, heat can be dissipated from all points of the infrared transmitter 220 via the heat dissipation plates 290 to further improve the heat dissipation effect.

[0141] Without restriction, the number of heat dissipation plates 291 can be one, two, three, or more. As a general rule, the greater the number of heat dissipation plates 291, the better the heat dissipation effect.

[0142] In some optional embodiments, the infrared heating device further comprises a mounting bracket 280, wherein the mounting bracket 280 is connected to the base 200, the infrared transmitter 220 and the heat dissipation base 292 such that both the infrared transmitter 220 and the heat dissipation element 290 are connected to the base 200 via the mounting bracket 280.

[0143] The mounting bracket 280 can confine and secure the infrared transmitter 220, effectively improving the reliability and strength of the connection between the infrared transmitter 220 and the base 200. It also effectively reduces or prevents wobbling of the infrared transmitter 220, which could damage it, thus improving the protection of the infrared transmitter 220 and extending its lifespan.

[0144] Furthermore, using the mounting bracket 280 for the simultaneous installation of the infrared transmitter 220 and the heat dissipation element 290 improves the utilization rate of the mounting bracket 280, which helps to save interior space in the base 200. For example, as shown in Fig. As shown in Figure 5, a surface of the reflection element 240 on a side facing the infrared transmitter 220 is a downwardly recessed, curved surface, wherein the curved surface and the transmission element together enclose a chamber 241.

[0145] The curved surface can collect the reflected infrared rays when reflecting the infrared rays, so that the reflected infrared rays can be collected and projected centrally onto the roller brush 110, which can effectively reduce or prevent the propagation of the infrared rays outwards, improve the utilization rate of the infrared rays and thereby effectively increase the heating and drying efficiency of the infrared transmitter.

[0146] For example, the shape of the longitudinal section of the reflection element 240 can be roughly designed as an ellipse (as in Fig. (Figure 6), and the infrared transmitter 220 is located at a focal point F1 of the elliptical reflecting element 240, which can be used to heat the water used for cleaning the roller brush during self-cleaning, in order to achieve high-temperature hot water cleaning of the roller brush. This portion of the radiant energy can heat the permeable parts, and during the drying process of the roller brush 110, a relatively high temperature of the permeable parts can be applied to the roller brush. This results in the roller brush being dry-ironed at a high temperature, which improves the drying efficiency of the roller brush and effectively reduces waste.

[0147] As in Fig. As shown in Figure 7, the reflection element 240 has an opening 242 on its underside, with the heat dissipation element 290 being located below the opening 242 in order to absorb the heat generated by the infrared transmitter 220 above it through the opening 242.

[0148] The reflection element 240 and the transmission element 230 can be directly connected to each other, or, as in Fig. As shown in Figure 6, the infrared heating device also includes a shock-absorbing pad 260, which is located at the connection point between the transmission element 230 and the reflection element 240. The transmission element 230 is connected to the reflection element 240 via the shock-absorbing pad 260, and the shock-absorbing pad 260 is able to absorb vibrational energy, thereby preventing damage to the transmission element 230 and the infrared transmitter 220 from vibrations.

[0149] As in the Fig. 4 and Fig. As shown in Figure 5, the base 200 can include a blower 250 located in the receiving chamber 213, the blower 250 having a blowing opening, and the airflow blown through the blowing opening can pass through the infrared transmitter 220 and the heat dissipation element 290. When the infrared transmitter 220 is switched on, the blower 250 can transfer the infrared heat emitted by the infrared transmitter 220 and the heat dissipated by the heat dissipation element 290 to the roller brush 110. When the infrared transmitter 220 is switched off, the blower 250 can also transfer the residual heat from the infrared transmitter 220 and the heat dissipation element 290 to the roller brush 110. As shown in Figure 5, the base 200 can include a blower 250 located in the receiving chamber 213, the blower 250 having a blowing opening, and the airflow blown through the blowing opening can pass through the infrared transmitter 220 and the heat dissipation element 290. Fig. As shown in Figure 3, the base 200 also includes a ventilation opening 271 located on a circumferential side of the roller brush 110, and an air duct 270 situated between the outlet of the blower 250 and the ventilation opening 271 (as shown in Figure 3). Fig. (as shown in Figure 4), wherein at least the infrared transmitter 220 and the heat dissipation element 290 are located in the air duct 270. The air duct assembly of the base 200 defines the air duct, and the airflow from the blowing opening of the blower 250 can drive the airflow around the infrared transmitter 220 and the heat dissipation element 290, thereby not only transferring the heat generated by the infrared transmitter 220 to the roller brush 110, but also dissipating the heat absorbed by the heat dissipation element 290 and transporting it to the roller brush 110 to further improve the drying effect on the roller brush 110. Furthermore, the air blown from the blowing opening can also lower the temperature near the infrared transmitter 220 and the heat dissipation element 290, thus improving the heat dissipation effect.

[0150] As in Fig. As shown in Figure 6, in some optional embodiments the infrared heating device further comprises a temperature detector 202. The temperature detector 202 can detect the air temperature near the infrared transmitter 220, and according to the temperature of the temperature detector 202, the operating parameters of the infrared transmitter 220 can be adjusted in a timely manner to maintain the appropriate amount of water and steam in the cleaning groove 211 and to ensure the cleaning effect on the roller brush 110.

[0151] The temperature detector 202 detects the lower air temperature instead of directly measuring the higher temperature of the infrared transmitter or the transmission element 230, which helps to reduce damage to the temperature detector 202.

[0152] For example, the temperature detector 202 is an NTC sensor (negative temperature coefficient sensor). However, it is not limited to that.

[0153] With reference to Fig. 6 at least part of the temperature detector 202 is located in chamber 241, and the infrared transmitter 220 is also located in chamber 241, so that the temperature detector 202 can measure the room temperature near the infrared transmitter 220.

[0154] For example, the temperature detector 202 can also be attached to a mounting bracket 280, or the temperature detector can also be attached to the base using other brackets.

[0155] The number of infrared transmitters 220 can be one, two, three or more.

[0156] Referring to Fig. 1. The cleaning device may further comprise a fresh water tank 101, wherein the fresh water tank 101 can supply the roller brush 110 with a cleaning fluid (including, but not limited to, cleaning water for cleaning the roller brush in the cleaning groove during the self-cleaning process) in order to moisten the roller brush 110, so that the roller brush 110 may be able to moisten the stains on the surface to be cleaned and reduce the adhesion of the stains during the cleaning process, thereby facilitating the cleaning of the stains from the surface to be cleaned.

[0157] Along the direction of travel of the floor brush 100, the roller brush 110 can be mounted at the front end of the housing and the wheel 102 at the rear end of the housing. This makes it easier to control the direction of travel of the floor brush 100, which is beneficial for maintaining the balance of the floor brush 100 during operation. Furthermore, the roller brush 110 comes into preferential contact with the surface to be cleaned, and its front is unobstructed, which facilitates the cleaning of the surface by the roller brush 110.

[0158] The cleaning device can also include a main body, and the floor brush 100 can be rotatably attached to the underside of the main body. During the cleaning process, a user can hold the main body and rotate the floor brush 100 relative to it by swiveling the main body. This allows the floor brush 100 to reach different areas (e.g., under a table, under a cabinet, etc.), enabling it to clean various surfaces. The main body is equipped with an internal suction device.

[0159] The main unit can be equipped with components such as a fresh water tank 101 and a wastewater tank. The fresh water tank 101 holds cleaning fluid, and when the cleaning device is in operation, the cleaning fluid in the water tank 101 is sprayed onto the floor brush 100 or the surface to be cleaned in front of the floor brush 100 to clean the surface in conjunction with the floor brush 100. The wastewater (along with particles, hair, and other foreign matter) on the surface to be cleaned is sucked into the wastewater tank to complete the cleaning process.

[0160] After the cleaning device has been returned to its base, self-cleaning, charging and other auxiliary functions of the cleaning device are performed.

[0161] The implementing entity of the embodiments of the present application can be a control unit in the cleaning device or a control unit in the base, or alternatively, the implementing entity can also be a server corresponding to the cleaning device and the base. The server is located in the cloud and is connected to the cleaning device via a network in order to issue control commands to the cleaning device and the base, or alternatively, to forward control commands sent by a user to the cleaning device and the base via an end device (e.g., a mobile phone, a portable device, or a computer, etc.), etc.

[0162] The control unit described above can contain a microcontroller unit (MCU). Of course, the control unit described above can also contain other devices that can perform control functions.

[0163] As in Fig. As shown in Figure 5, the base 200, for example, has an input / output interface 201 for signals. When the cleaning device 100 is placed on the base 200, the signal interface of the cleaning device 100 is electrically connected to the input / output interface 201 for signals of the base 200, and a user can press a self-cleaning button on the cleaning device 100 to send a self-cleaning command to the control unit. The control unit activates the infrared transmitter based on the self-cleaning command and controls the corresponding components of the cleaning device and the base to perform a self-cleaning action.

[0164] The cleaning system is configured with a drying mode, wherein the water distributor is configured to be in a closed state in the drying mode, wherein the heating device is configured to be in a heating state in the drying mode, and wherein the roller brush is configured to be in a rotating state and in contact with the heating device in the drying mode in order to iron the roller brush through the heating device.

[0165] Furthermore, in drying mode, the roller brush is configured to have a positive rotation in a final movement before stopping the rotation.

[0166] The cleaning system is further configured to control the heating device so that it stops the heating and keeps the roller brush rotating when the drying mode is complete.

[0167] The cleaning system is configured to control the cleaning system to enter a spin-drying mode before the cleaning system is controlled to enter a drying mode, wherein in the spin-drying mode the cleaning system controls the heating device to be in a heating state, and wherein the roller brush is in contact with the heating device so that the roller brush can be ironed by the heating device while it is being spun.

[0168] The blower is configured to be activated in drying mode to blow heat away from the heat dissipation element in a direction facing the roller brush.

[0169] The self-cleaning process is described below in conjunction with the Fig. Figures 7 to 10 of the attached drawings describe an example in which the execution subject is a control unit in a cleaning device. Example 2

[0170] As in Fig. Figure 8 shows step S10: Controlling the cleaning device in response to a spin command to enter a spin mode; during spin mode, the water distributor remains closed while the roller brush rotates; in addition, during spin mode, the infrared heating device operates in heating mode, with the roller brush in contact with the transmission element to allow simultaneous ironing of the roller brush by the transmission element during the spin process.

[0171] The self-cleaning process in the embodiment of the present application comprises the following: washing, spinning and drying.

[0172] The spin-dry command can be included within the self-cleaning commands. In this case, the spin-drying phase can be initiated after the water wash cycle is complete. Alternatively, the spin-dry command can be a separate command, independent of the self-cleaning command.

[0173] Modern floor scrubbers often perform a self-cleaning cycle after completing their cleaning tasks. Existing self-cleaning systems are typically time-consuming and frequently use PTC or heating wires to directly heat water for hot water cleaning. Higher-quality machines will incorporate a separate set of heating wires to generate hot air for drying; therefore, most floor scrubbers will utilize two heat sources for both water heating and drying.

[0174] Furthermore, the brush is primarily dried with hot air, leaving the roller brush bristles in a disordered state after drying. When the roller brush is cleaned in this condition, the moisture content is uneven, and because some of the bristles are standing upright, the contact with components such as the roller brush cover increases, resulting in a very high inrush current.

[0175] The solution of the embodiments of the present application enables both a more compact structure and improved self-cleaning efficiency and effect, as will be explained in more detail below.

[0176] First, in the embodiments of the present application, a single heat source, i.e., an infrared heating device, is used throughout the entire water washing and drying phase. In particular, the present application achieves multifunctional self-cleaning without the need for multiple heating devices. The advantage lies in the simplified control logic for both drying and self-cleaning heating, eliminating the need for constant switching between different heating components. It should be noted that each heating component requires a significant inrush current and a considerable preheating time. By using a single heat source, these problems are completely avoided. This eliminates the switching time and preheating time associated with multiple heat sources. Combined with the rapid heating characteristic of infrared devices, the overall efficiency of the self-cleaning process is significantly improved.

[0177] Secondly, the embodiments of the present application achieve higher cleaning efficiency through multiple structures and logical control. In particular, the infrared heating device is activated after the water washing process, i.e., during the spin cycle. It should be taken into account that only minimal amounts of water remain on the base during the spin cycle (since the wastewater is extracted after washing) and that the roller brush and the transmission element remain in contact.

[0178] Furthermore, the transmission element operates at a high temperature. Consequently, the roller brush can be ironed on the transmission element simultaneously during the spin cycle. The shapes of the transmission element and the roller brush are matched, as both are curved. This ironing effect of the transmission element allows the roller brush to dry faster while simultaneously ensuring it remains flatter.

[0179] Thirdly: Since the drying process begins during the spin cycle, the roller brush is dried simultaneously with the spin cycle.

[0180] In particular, since the spin cycle has already begun during the subsequent drying process, the following preheating and heating times are eliminated, allowing the drying phase to begin immediately. Furthermore, heating takes place during the spin cycle, resulting in moisture evaporation due to the temperature. Consequently, the solution of the present application significantly improves the overall efficiency of the self-cleaning process and enhances the self-cleaning effect by incorporating heating and ironing during the spin cycle.

[0181] Fourth: Conventional heating methods predominantly use hot air. Consequently, the power consumption of the fan is often considerable. In contrast, the present application primarily utilizes infrared heating, which operates more quietly and does not require special high-powered fans to facilitate drying. Therefore, the use of the aforementioned infrared heating method reduces the overall noise generated during the self-cleaning process, resulting in an essentially noiseless washing and drying function.

[0182] In some optional embodiments, the infrared heating device comprises the above heat dissipation element, wherein the heat dissipation element is located below the infrared transmitter; wherein the base further comprises the above blower; wherein the self-cleaning method comprises controlling the blower in spin mode so that it is switched on to blow the heat away from the heat dissipation element in the direction facing the roller brush.

[0183] It is understood that the heat dissipation element of the embodiments of the present application serves to absorb excess light or heat emitted by the infrared transmitter and thus prevent other components of the base from being damaged by excessive heat. In particular, it mainly concerns the heat emitted below the infrared transmitter, for which a fan is provided. The fan can be selected as a low-power fan, which serves to dissipate the heat accumulated on the heat dissipation element and thus distribute the concentrated heat.

[0184] In other words, the heat dissipation element absorbs and concentrates the heat emitted by the infrared transmitter, which is then conducted by the fan to the heat dissipation element to achieve heat dissipation. Accordingly, the heat dissipation element can be dark in color, for example, black or gray.

[0185] Additionally, an air duct is integrated into the base. Heat from the heat dissipation element is dissipated by the blower, and the air duct outlet faces the roller brush. The coordinated interaction of the blower, the heat dissipation element, the infrared transmitter, and the air duct achieves multi-stage heating of the roller brush while simultaneously preventing the base from burning. Specifically, this design provides the roller brush with both direct heating from the infrared transmitter and hot air heating from the heat dissipation element. This single device thus implements multiple heating modes, offering more heating options and a superior heating effect compared to prior art.

[0186] In some optional embodiments, the cleaning device further includes a detection device, and the self-cleaning procedure includes the following: controlling the cleaning device to perform a self-cleaning action prior to executing the spin cycle;

[0187] The self-cleaning process includes the following: Controlling the cleaning device in response to a self-cleaning command to enter an initial cleaning mode, wherein the initial cleaning mode includes a first cleaning phase and a second cleaning phase; Control in the first cleaning mode so that the infrared heating device is activated, the water distributor sprays water and the roller brush rotates; Controlling the detection device to assess dirt detection based on the condition of the roller brushes after completion of the first cleaning phase by the cleaning device and to proceed with the execution of the second cleaning phase; wherein the condition of the roller brushes includes a slightly dirty condition, a moderately dirty condition and a heavily dirty condition.

[0188] In the embodiments of the present application, the cleaning device responds directly to the self-cleaning command during the self-cleaning process and switches directly to the self-cleaning state based on this command. It is controlled to enter the first cleaning mode, which is divided into two phases. After the first cleaning phase has been completed, a dirt detection action begins. This ensures that a cleaning device, such as a floor scrubber, can execute the self-cleaning action immediately. If the cleaning device were configured to first evaluate a self-cleaning command after its detection, the floor scrubber would inevitably require a reaction time before actually switching to self-cleaning mode.Excessively long response times lead to an increase in the time between command capture and execution completion, which significantly impairs the user experience.

[0189] In other words, this self-cleaning process always immediately performs the first cleaning mode, regardless of the selected cleaning mode. The first cleaning mode is configured to activate the infrared heating device, spray water from the water distributor, and rotate the roller brush. This ensures that heated water is used for heating during the first cleaning mode, allowing dirt to dissolve more quickly and easily in the initial self-cleaning phase. This facilitates preparation for the subsequent cleaning modes, which correspond to the different states of the roller brush.

[0190] The detection devices include, among other things, color sensors, e.g., RGB dirt detectors.

[0191] RGB dirt detector refers to a device with a color system detection function (Red Green Blue, RGB).

[0192] The RGB dirt detector can accurately capture color, brightness, and other environmental information, facilitating the differentiation between stains and other environmental data, thus improving the accuracy of stain identification. It can also distinguish between different levels of contamination based on color, brightness, and other factors, further enhancing the accuracy of identifying these varying degrees.

[0193] In some optional embodiments, the water spraying by the water distributor is stopped during the first cleaning phase as soon as the spray volume reaches 45 ml to 55 ml;

[0194] During the second cleaning phase, the water spraying by the water distributor is stopped as soon as the spray volume reaches 45 ml to 55 ml;

[0195] After the water spraying by the water distributor has ended during the first cleaning phase and before the water spraying begins during the second cleaning phase, the suction device is activated to perform a suction action.

[0196] Furthermore, the first cleaning mode is divided into two phases, with the amount of water also being divided into two phases to ensure that the amount of water in each phase is controlled within 45 ml to 55 ml.

[0197] For example, if the duration of the first cleaning phase is set to 6 seconds and a spray volume of 2 seconds is sufficient to meet the requirement, the water distributor will be controlled to stop spraying after 2 seconds. The purpose of controlling the above water volume is as follows.

[0198] First, since this is the initial phase, the current level of soiling in the floor scrubber is still unknown. Controlling the water volume prevents waste. Because the infrared transmitter has just been put into operation, it takes some time to reach the target temperature. Controlling the water volume ensures that the water quickly reaches a suitable temperature, for example, 60°C.

[0199] Secondly, since the first cleaning mode is divided into two phases, allocating a specific amount of water to each phase allows for multiple cleanings with a small amount of water, thus improving the cleaning effect without wasting water.

[0200] The amount of water used in the first cleaning phase and in the second cleaning phase can be the same or approximately the same.

[0201] For example, the amount of water in the first cleaning phase is 45 ml, 50 ml or 55 ml, and the amount of water in the second cleaning phase is 45 ml, 50 ml or 55 ml.

[0202] In some optional embodiments, the cleaning device is controlled so that it enters a spin-drying mode at the end of a first cleaning mode if the soiling condition of the roller brush is a slightly soiled condition;

[0203] If the soiling condition of the roller brush is moderately soiled, the cleaning device is controlled so that after the end of the first cleaning mode it enters an immersion washing mode and after the execution of the immersion washing mode it enters a spin-drying mode;

[0204] The immersion wash mode includes the following: controlling the infrared heating device, the water distributor spraying water, and the roller brush rotating, with a spray volume between 70 ml and 90 ml.

[0205] The above solution introduces a cleaning method for slightly soiled and moderately soiled conditions. If slightly soiled, the roller brush can be cleaned after just two hot water cleaning cycles in the first cleaning mode. This eliminates the need to waste resources or time on further cleaning, thus further controlling the self-cleaning time and preventing resource waste.

[0206] If a moderately soiled condition is detected after the two hot water cleaning phases in the first cleaning mode have been completed, the immersion wash mode is initiated. The immersion wash mode is configured with a larger spray volume, and the water volume is controlled to be between 70 ml and 90 ml (the specific volume can be 70 ml, 80 ml, or 90 ml) to ensure that the bristles of the roller brush in contact with the floor are fully immersed, while the infrared heating element remains activated. In other words, the two hot water cleaning phases of the first cleaning mode and the self-cleaning function of the immersion wash mode are used in moderately soiled conditions to further enhance the cleaning effect of the roller brush.

[0207] In some optional embodiments, the cleaning device is controlled to enter a heavy soiling cleaning mode at the end of a first cleaning cycle if the roller brush is heavily soiled. The heavy soiling cleaning mode includes the following: activating the infrared heating device, spraying water from the water distributor, rotating the roller brush with a spray volume between 50 ml and 70 ml, and controlling the water temperature in the cleaning groove between 90°C and 100°C. If a heavy soiling condition is detected, the device switches to high-temperature self-cleaning (i.e., the heavy soiling cleaning mode) after completing the two hot water self-cleaning phases of the first cleaning cycle.At this point, the spray volume is controlled to be between 50 ml and 70 ml to ensure that the above amount of water can be heated quickly to 90°C to 100°C and that a high temperature and a larger amount of water can be used to achieve high-temperature cleaning and dissolution, thus ensuring the above cleaning effect of the roller brush.

[0208] In other words, the present application represents an intelligent cleaning method. By directly entering the first cleaning mode, which is divided into two phases, and assessing the condition of the roller brush during the second phase to determine the next cleaning action, both the rapid realization of self-cleaning and the effectiveness of the self-cleaning effect are ensured through intelligent assessment, thus achieving maximum cleaning efficiency. Simultaneously, the infrared heating device undergoes all phases of self-cleaning, further guaranteeing the cleaning effect.

[0209] The spray volume in cleaning mode for heavy soiling can be 50 ml, 60 ml or 70 ml, and the water temperature can be 90°C or 100°C, but is not limited to these.

[0210] In some embodiments, the water temperature in immersion wash mode is lower than the water temperature in heavy soil cleaning mode. The water volume (i.e., the spray volume) in immersion wash mode is greater than the water volume in heavy soil cleaning mode. Example 3

[0211] A self-cleaning method is applied to the cleaning system of one of the embodiments of the above embodiment 1, wherein the cleaning system comprises a cleaning device and a base, wherein the cleaning device comprises a main body and a floor brush, wherein the floor brush is provided internally with a roller brush and a water distributor, wherein the main body is provided with a suction device; wherein the base is provided with a cleaning groove for receiving the roller brush, wherein the base is provided internally with an infrared heating device to heat the roller brush, wherein the infrared heating device comprises an infrared transmitter and a transmission element located below the roller brush.

[0212] As in Fig. As shown in 9, the self-cleaning process includes the following: S110: Controlling the cleaning device in response to a drying command to enter a drying mode; wherein the water distributor is in a closed state in the drying mode, the roller brush is rotating, and the infrared heating device is in a heating state; S120: Controls the infrared heating device to stop heating when the drying mode is finished; S130: Control the roller brush so that it remains in a rotating state for a predetermined time after the infrared heating device stops heating.

[0213] The embodiments of the present application provide an infrared heating solution for the embodiment in which the infrared heating device goes through the entire process of cleaning the roller brush, including the self-cleaning process as well as the spin-drying and drying phase, i.e. a single heating device is used to meet the heating requirements of the different phases while ensuring maximum drying efficiency and saving energy.

[0214] In the drying phase described above, the infrared heating device is controlled directly so that the heating is stopped after a certain time, but at this point the temperature on the transmission element is still high. This residual temperature can then be used for further drying. In other words, with the prior art, the heating device often needs to be switched on for 30 minutes to achieve the effect of high-temperature drying. With this solution, the infrared heating device only needs to be switched on for 25 minutes, and then the residual temperature can be used to complete the heating and drying process.

[0215] During residual heat heating, the roller brush rotates, and the brush bristles and the transmission element are in contact. This residual heat creates an ironing effect, ensuring that the brush bristles are flattened at the end of the drying process. Simultaneously, the rotation of the roller brush prevents the bristles from being held at an angle, which would otherwise lead to bristle burn.

[0216] The drying command can, for example, also be a command included in the self-cleaning commands. In response to the self-cleaning command, the control unit can automatically enter a drying phase after cleaning and spinning the roller brush.

[0217] In some optional embodiments, step S130 includes the following: controlling the roller brush to rotate alternately forwards and backwards.

[0218] Reversing the rotation of the roller brush allows the bristles to point upwards, facilitating heat transfer into the brush's interior and improving drying efficiency. Forward rotation flattens the bristles by utilizing the contact between the brush and the transmission element, ensuring a flatter brush head. Therefore, alternating forward and reverse rotation improves drying efficiency and effectiveness while reducing the risk of brush burnout. Additionally, the final forward rotation before stopping can be configured to soften the bristles and ensure a flatter brush head.

[0219] Other steps of the self-cleaning process of the embodiments of the present application can be described in embodiment 2, e.g. the above spin-drying phase can be carried out before the drying phase, the above first cleaning mode can be carried out during the spin-drying phase, and the immersion washing mode or the heavy soiling cleaning mode can be carried out depending on the condition of the roller brushes, etc., which will not be repeated and described here.

[0220] Other structures of the cleaning system of the embodiments of the present application are described in embodiment 1, e.g. the infrared heating device comprises at least one of a heat dissipation element, a reflection element, a blower and a mounting bracket, etc., and is not described again here.

[0221] Each embodiment or embodiment of the present application is described step by step, and, provided that they do not contradict each other, each embodiment can be combined with any other to form a new embodiment. Example 4

[0222] A self-cleaning method is applied to the cleaning system of one of the embodiments, wherein the cleaning system comprises a cleaning device and a base, wherein the cleaning device comprises a main body and a floor brush, wherein the floor brush is provided internally with a roller brush and a water distributor, wherein the main body is provided with a suction device; wherein the base is provided with a cleaning groove for receiving the roller brush, wherein the base is provided internally with a detection device and an infrared heating device, wherein the infrared heating device serves to heat the roller brush, and wherein the infrared heating device comprises an infrared transmitter and a transmission element located below the roller brush.

[0223] As in Fig. As shown in Figure 10, the self-cleaning procedure comprises the following: Step S210: Controlling the cleaning device in response to a self-cleaning command to enter an initial cleaning mode, the initial cleaning mode comprising a first cleaning phase and a second cleaning phase; controlling the device in the initial cleaning mode to activate the infrared heating device, spray water from the water distributor, and rotate the roller brush;

[0224] Step S220: Control the detection device to assess dirt detection based on the condition of the roller brushes after completion of the first cleaning phase by the cleaning device and to proceed with the execution of the second cleaning phase;

[0225] In the embodiments of the present application, the cleaning device responds directly to the self-cleaning command during the self-cleaning process and switches directly to the self-cleaning state based on this command. It is controlled to enter the first cleaning mode, which is divided into two phases. After the first cleaning phase has been completed, a dirt detection action begins. This ensures that a cleaning device, such as a floor scrubber, can execute the self-cleaning action immediately. If the cleaning device were configured to first evaluate a self-cleaning command after its detection, the floor scrubber would inevitably require a reaction time before actually switching to self-cleaning mode.Excessively long response times lead to an increase in the time between command capture and execution completion, which significantly impairs the user experience.

[0226] In other words, this self-cleaning process always immediately performs the first cleaning mode, regardless of the selected cleaning mode. The first cleaning mode is configured to activate the infrared heating device, spray water from the water distributor, and rotate the roller brush. This ensures that heated water is used for heating during the first cleaning mode, allowing dirt to dissolve more quickly and easily in the initial self-cleaning phase. This facilitates preparation for the subsequent cleaning modes, which correspond to the different states of the roller brush.

[0227] The degree of soiling can be detected with a dirt detector. For example, the condition of the roller brushes includes, among others, a slightly soiled state, a moderately soiled state, and a heavily soiled state, with the degree of soiling increasing in this order.

[0228] Heating the cleaning water with the infrared transmitter can improve the dissolution of the dirt and increase the cleaning effect.

[0229] The self-cleaning process in the embodiment of the present application comprises the following steps in succession: washing, spinning, and drying. It is understood that steps S210 and S220 are both steps of the washing phase (also known as water washing) of the self-cleaning process.

[0230] In some optional embodiments, determining the degree of contamination of the roller brush includes the following: Step S211: Determining the roller brush condition based on RGB information detected by the RGB dirt detector.

[0231] RGB dirt detector refers to a device with a color system detection function (Red, Green, Blue, RGB). It should be understood that the term "dirt detector" can also refer to other types of detectors and is not limited to this.

[0232] The RGB dirt detector can accurately capture color, brightness, and other environmental information, facilitating the differentiation between stains and other environmental data, thus improving the accuracy of stain identification. It can also distinguish between different levels of contamination based on color, brightness, and other factors, further enhancing the accuracy of identifying these varying degrees.

[0233] In some optional embodiments, the self-cleaning procedure prior to step S210 may further include the following: Performing a blockage test on the roller brush, wherein the blockage test comprises controlling the roller brush to rotate alternately forwards and backwards, wherein the backward rotation angle of the roller brush is less than 360°. The blockage test immediately determines whether the roller brush is blocked, protects the roller brush motor from overcurrent, and ensures the safety of the operating process.

[0234] During reverse rotation, a reverse rotation angle of less than 360° for the roller brush reduces tangling and other debris ejected from the front of the brush. This allows the debris to be more effectively directed to a dirt suction opening in the floor brush and then collected under the effect of negative pressure. This further improves the cleaning effect of the dirt on the roller brush.

[0235] The alternating forward and reverse rotation of the roller brush also contributes to further improving the cleaning effect on the tangles. For example, when the roller brush motor drives the cleaning element to a forward rotation, the scraper strip on the bottom brush can be used to collect and cut the tangles, and the reverse rotation of the roller brush can loosen the tangles that have become lodged on the roller brush. Once the tangles are freed, the roller brush can be rotated forward again so that the scraper strip can collect and cut the tangles once more, thus allowing the tangles to be cleaned by the alternating forward and reverse rotation during the blockage test.

[0236] In some optional embodiments, the reverse rotation angle of the roller brush is 280° to 340°, wherein the starting point of the reverse rotation angle is a contact point O between the roller brush and the transmission element (as in Fig. 4 shown) and the line between the contact point and the axis of the roller brush (the vertical dashed line in Fig. 4) runs perpendicular to a horizontal plane (horizontal dashed line in Fig. 4) The “Contact Point O” is located in Fig. 4 is shown and is also approximately the point where the horizontal plane touches the underside of the roller brush 110.

[0237] For example, the reverse rotation angle of the roller brush can be 280°, 290°, 300°, 310°, 320°, 330° or 340°.

[0238] The reverse rotation angle of the roller brush from 280° to 340° can better prevent the dirt from being ejected from the front of the roller brush, and the dirt can be brought to the dirt suction opening of the floor brush more frequently.

[0239] In particular, most of the dirt in conventional machines is located in the roller brush cover, water distributor, scraper strip, etc., and by using reverse rotation, the dirt in these areas can be cleaned more effectively. The contact position between the roller brush and the base is defined as the starting point, and then the reverse rotation angle of the roller brush is set to 280° to 340° to ensure that the roller brush can be cleaned up to the aforementioned position by rotating backward. In other words, controlling the reverse rotation angle of 280° ensures that the roller brush can be cleaned at least up to the positions including the roller brush cover to achieve the aforementioned dirt removal.The 340° setting ensures that the dirt above is definitely not ejected by the roller brush drive, and at the same time it can move the dirt into the dirt suction position above, which not only ensures the cleaning effect but also prevents the dirt from appearing in other positions.

[0240] In some optional embodiments, performing a roller brush blockage test includes the following: Controlling the motor of the roller brush to rotate the roller brush forward for a first predetermined time, then controlling the motor of the roller brush to rotate the roller brush backward for a second predetermined time;

[0241] Determining a blockage of the roller brush rotation in response to a current in the roller brush motor being greater than or equal to a first current value during the forward rotation of the roller brush, and / or in response to a current in the roller brush motor being greater than or equal to a second current value during the reverse rotation of the roller brush; wherein the second current value is greater than the first current value.

[0242] The blockage test immediately determines whether the roller brush is blocked, protects the roller brush motor from overcurrent, and ensures the safety of the operating process.

[0243] In some embodiments, the alternating forward and reverse rotation of the roller brush is repeated at least N times. As a result, the blockage test is passed and the self-cleaning action is performed, provided that the current of the roller brush motor is less than the first current value during each forward rotation and less than the second current value during each reverse rotation. Here, N is a positive integer greater than or equal to 1. For example, N can be 1, 2, 3, 4, 5, 6, or more times.

[0244] For example, the first predetermined time is 0.8s to 2.0s and the second predetermined time is 0.6s to 2.0s. For example, the first predetermined time is 1.0s and the second predetermined time is 0.8s.

[0245] For example, the first current value is 2.0 A to 3.0 A and the second current value is 3.0 A to 5.0 A. For example, the first current value is 2.0 A and the second current value is 4.0 A. Or the first current value is 2.5 A and the second current value is 4.5 A.

[0246] For example, if a rotation blockage is detected, the control unit can issue a warning to remind the user to manually clear the obstruction. In this case, the control unit can control the cleaning unit and its associated base station components to stop operation and resume blockage detection and subsequent self-cleaning after the user has cleared the blockage and issued the self-cleaning command again. In some optional embodiments, the self-cleaning procedure further includes the following: Controlling the cleaning device so that it enters a spin cycle at the end of an initial cleaning mode if the soiling condition of the roller brush is a slightly soiled state; Controlling the cleaning device to enter a second cleaning mode when the roller brush condition is moderately dirty or heavily dirty, in the event that the second cleaning phase is completed; wherein the temperature of the cleaning water in the second cleaning mode, when the roller brush condition is moderately dirty, is lower than the temperature of the cleaning water in the second cleaning mode, when the roller brush condition is heavily dirty.

[0247] The above solution introduces a cleaning method for lightly soiled, moderately soiled, and heavily soiled conditions. If light soiling is detected, the current roller brush can be cleaned and moved to the spin cycle after just two hot water cleaning cycles in the first cleaning mode. This eliminates the need to waste resources or time on further cleaning, thus further controlling the self-cleaning time and preventing resource waste.

[0248] If a moderately or heavily soiled condition is detected after the two hot water cleaning phases of the first cleaning mode have been completed, the second cleaning mode is initiated. The second cleaning mode is configured with a higher spray volume and / or a higher water temperature, while the infrared heating element remains activated. This means that the two hot water cleaning phases of the first cleaning mode and the self-cleaning function of the second cleaning mode are utilized in moderately or heavily soiled conditions to further ensure the cleaning effect of the roller brush.

[0249] In some optional embodiments, the self-cleaning process further includes the following: In the second cleaning mode, the temperature of the cleaning water is controlled by providing different amounts of water, with the amount of cleaning water being negatively correlated with the temperature of the cleaning water.

[0250] If the other conditions are the same or nearly the same (e.g., the infrared transmitter's power is unchanged, the heating time is the same or not very different), the larger the volume of cleaning water, the lower the water temperature; conversely, the smaller the volume of cleaning water, the higher the water temperature. Water volume and water temperature are negatively correlated. By controlling the water volume, the water temperature can be controlled more easily and conveniently.

[0251] In some optional embodiments, the second cleaning mode includes an immersion wash mode. If the roller brush is moderately dirty, the cleaning device is controlled to enter an immersion wash mode after the first cleaning mode has finished, and then to enter a spin-dry mode after the immersion wash mode has been completed.

[0252] The immersion wash mode includes the following: controlling the infrared heating device, the water distributor spraying water, and the roller brush rotating, with a spray volume between 70 ml and 90 ml.

[0253] The beneficial effects of immersion washing are described in the previous description and are not repeated here.

[0254] In some optional embodiments, the second cleaning mode includes a cleaning mode for heavy soiling;

[0255] Controlling the cleaning device so that at the end of a first cleaning mode it enters a heavy soiling cleaning mode if the soiling condition of the roller brush is heavily soiled;

[0256] The heavy soiling cleaning mode comprises the following: Controlling the system so that the infrared heating device is activated, the water distributor sprays water, the roller brush rotates, with the spray volume between 50 ml and 70 ml, and the water temperature in the cleaning groove is controlled between 90°C and 100°C. The beneficial effects of the heavy soiling cleaning mode are described in the previous section and are not repeated here.

[0257] In some optional embodiments, the water spraying by the water distributor is stopped during the first cleaning phase as soon as the spray volume reaches 45 ml to 55 ml;

[0258] During the second cleaning phase, the water spraying by the water distributor is stopped as soon as the spray volume reaches 45 ml to 55 ml;

[0259] After the water spraying by the water distributor has finished during the first cleaning phase and before the water spraying begins during the second cleaning phase, the suction device is activated to perform a suction action. The beneficial effects are described in the previous description and are not repeated here.

[0260] Optionally, the drying mode can be selected after the spin cycle described above has finished. The self-cleaning process also includes the following: Controlling the infrared heating device to stop the heating when the drying mode is finished; Controlling the roller brush so that it remains in a rotating state for a predetermined time after the infrared heating device stops heating. The beneficial effects are described in the previous description and are not repeated here.

[0261] In some optional embodiments, the base further comprises a temperature detector, wherein both the temperature detector and the infrared transmitter are located in the chamber formed by the common enclosure of the above reflective element and the transmitting element, wherein the infrared transmitter of the temperature detector is used to detect the air temperature near the infrared transmitter.

[0262] The temperature detector detects the lower air temperature, rather than directly measuring the higher temperature of the infrared transmitter or transmission element, which helps to reduce damage to the temperature detector.

[0263] In some optional embodiments, the self-cleaning method further includes: controlling operating parameters of the infrared transmitter so that the temperature detected by the temperature detector is between 90°C and 120°C, with the temperature of the transmission element being able to reach between 220°C and 260°C.

[0264] If the temperature is below 90°C, the temperature of the transmission element makes it difficult to heat the liquid on it to a higher temperature (e.g., 100°C). A temperature that is too high, e.g., above 120°C, leads to an excessive temperature rise, resulting in the formation of too much steam and too little water. Conversely, a temperature between 90°C and 120°C ensures that the correct amount of water remains on the transmission element during the washing phase and that the correct amount of steam is generated. In other words, within this temperature range, it is possible to dissolve the dirt at a high temperature, obtain a specific amount of water to achieve an immersion effect, and utilize the high temperature of the steam for sterilization, thus effectively improving the washing effect during the washing phase.

[0265] Operating parameters include, among other things: power, heat generation time, and the like.

[0266] In some embodiments, the temperature detected by the temperature detector is controlled to range from 90°C to 115°C. For example, by controlling the operating parameters of the infrared transmitter, the temperature detected by the temperature detector is set to 90°C, 100°C, 110°C, or 115°C.

[0267] In some embodiments, the temperature during the spin-drying phase is set to 90° to 115°C, preferably 110°C.

[0268] Other elements not mentioned in this embodiment are the same as in embodiment 2, and the description is not repeated.

[0269] As an example, the cleaning device is presented as a floor scrubber, and the general sequence of the self-cleaning process for the floor scrubber includes: S310: Connecting the floor scrubber via the signal output interface to the signal input interface of the base and transmitting the signal; S311: Activating the carbon fiber heating tube (i.e., the infrared transmitter), the current flows through the carbon fiber, causing the molecules in the carbon fiber to move, converting electrical energy into heat energy and releasing it quickly and evenly into the external environment in the form of far-infrared radiation to achieve the heating effect; For the infrared band with concentrated light radiation between 1.5 µm and 15 µm, the absorption wavelength for organic substances and the intensity of the infrared radiation were increased by more than 30%, resulting in a strong infrared radiation effect. S312: The user sends a self-cleaning and drying signal (i.e., a self-cleaning command) to the main control board (i.e., the control unit) by pressing the handle button on the floor scrubber; S313: After the base control board receives the signal, it receives the self-cleaning command, switches on the infrared device, performs the blockage test, controls the activation of the blower at the rear end, and then the carbon fiber heating tube starts working, generating infrared radiation with a specific wavelength, focusing the infrared radiation through the reflective element and radiating it evenly through the translucent part on the roller brush, which rotates at a constant speed during the drying process (there is a forward and reverse rotation in the roller brush);

[0270] During the cleaning, spinning and drying process after the blockage test, the temperature and humidity control system monitors the moisture of the roller brush, the temperature of the drying environment and other parameters in real time and automatically adjusts the radiation intensity of the carbon fiber heating tube to achieve more accurate drying control.

[0271] S314: The blockage test consists of a 1-second forward rotation followed by a 0.8-second reverse rotation with a reverse angle of 300° to 340°. The purpose of the reverse rotation, without completing a full circle, is to prevent debris from being ejected. It is also possible to rotate the debris only near the dirt suction opening. The forward and reverse rotations are performed alternately five times. If the reverse angle of the roller brush is 330° and the current of the roller brush motor during the forward rotation is 2A or less, this indicates that it is not blocked.If the current of the roller brush motor during forward rotation is 2A or more, it means that it is blocked; if the current of the roller brush motor during reverse rotation is 4A or less, it means that it is not blocked, and if the current of the roller brush motor during reverse rotation is more than or equal to 4A, it means that it is blocked.

[0272] S315: After the blockage test, the hot water wash phase is initiated and is divided into two phases: the first cleaning phase and the second cleaning phase. After the first cleaning phase, the RGB dirt detector is used to detect dirt, and different self-cleaning modes are selected depending on the degree of soiling. Specifically: if a lightly soiled phase is detected, it proceeds directly to the spin cycle after the second cleaning phase; if a moderately soiled phase is detected, it proceeds to the immersion wash phase after the second cleaning phase; if a heavily soiled phase is detected, it proceeds to the high-temperature wash phase (100°C) after the second cleaning phase. The water volume in the hot water wash phase is 100 ml, the water volume in the high-temperature wash phase is 60 ml, and the water volume in the immersion wash phase is 80 ml.

[0273] The temperature during the spin cycle is set to 90° to 120°C, preferably 110°C. S316: The infrared transmitter is activated during the blockage test and remains activated until the end of the self-cleaning cycle.

[0274] The base is equipped with an NTC thermostat that detects the ambient temperature. The detection temperature range is from 90°C to 115°C. Below 90°C, the temperature of the transmission element is insufficient to heat the liquid on it to 100°C. Conversely, above 115°C, the temperature rises too high, resulting in excessive steam production and insufficient water flow. The 90°C to 115°C temperature range, combined with the three self-cleaning modes mentioned above, ensures the correct temperature, water volume, and steam output. This allows the high temperature to not only dissolve dirt but also achieve a certain degree of immersion in the water, while the high steam temperature is also available for sterilization.

[0275] S317: Simultaneously, after the spin cycle ends, the drying phase begins. During the drying phase, the infrared emitters continue to heat up. The roller brush can be ironed during both the spin and drying phases. After the drying cycle is complete, the infrared emitters stop heating, but the roller brush does not stop rotating immediately. Instead, it rotates alternately forwards and backwards to utilize the residual heat for heating and to prevent the roller brush from burning. For this reason, the roller brush continues to rotate for a certain period even after the spin cycle has ended. The blower can be switched on during this time.

[0276] Furthermore, the present application comprises a computer-readable storage medium wherein computer-executable instructions are stored on the computer-readable storage medium, wherein, when a processor executes the computer-executable instructions, the above self-cleaning procedure is implemented.
