Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and in particular to a self-cleaning method and a cleaning system. Background Art

[0002] With the development of science and technology and the improvement of living standards, household cleaning equipment such as floor scrubbers and sweepers and mops have become increasingly popular, reducing the burden of human housework.

[0003] Taking a floor scrubber as an example, after the floor scrubber is placed back on the base after the cleaning work is completed, it performs self-cleaning. The cleaning process of the roller brush is generally divided into two steps: washing the roller brush with hot water and drying the roller brush with heat. In the current floor scrubber base, the two steps are completed using two different structures. In the hot water washing stage, the water for cleaning the roller brush is heated by setting a heating component such as a PTC (positive temperature coefficient) heater under the base of the roller brush receiving groove on the base. In the hot drying stage, the heated air around the resistance wire is usually blown to the surface of the roller brush through the air duct in the base by heating with a resistance wire and blowing with a fan. However, the above two sets of structures are complex, which not only increases the difficulty of assembly, but also increases the manufacturing cost. More importantly, the overall time of the above self-cleaning is long, and the drying effect is not uniform. After the self-cleaning is completed, the roller brush hairs often explode, resulting in poor cleaning effect when cleaning again and high starting current. Summary of the invention

[0004] In view of this, embodiments of the present disclosure provide a self-cleaning method and a cleaning system.

[0005] According to a first aspect of an embodiment of the present disclosure, a self-cleaning method is provided, which is applied to a cleaning system, wherein the cleaning system comprises a cleaning device and a base, wherein the cleaning device comprises a body and a floor brush, wherein a roller brush and a water separator are arranged in the floor brush, and wherein a suction device is arranged in the body; The base is provided with a cleaning groove for accommodating the roller brush, and the base is provided with an infrared heating device, which includes an infrared emitter and a transmission member, and both are located below the roller brush; The self-cleaning method comprises: In response to the spin-drying instruction, controlling the cleaning device to enter a spin-drying mode; In the spin-drying mode, the water separator is in a closed state and the roller brush rotates; and in the spin-drying mode, the infrared heating device is in a heating state, and the roller brush contacts the transmissive member, so that the roller brush can be ironed by the transmissive member while being spun dry.

[0006] Current floor scrubbers often perform self-cleaning after cleaning, and the existing self-cleaning often takes a long time. They usually use PTC or heating wires to directly heat hot water to achieve hot water cleaning. High-end machines will also add a set of heating wires to heat the air for drying. For this reason, common floor scrubbers use two heat sources to achieve hot water heating and drying.

[0007] In addition, the drying method mainly adopts a separate hot air drying method. In the spin-drying stage, the roller brush is in a high-speed spinning state. If it is dried only by hot air, it will cause scattered water to splash everywhere. At the same time, the roller brush hair will become very messy due to the hot air blowing. Based on this, the spin-drying effect in the current technology is not good, and it cannot save a lot of drying time for subsequent drying work. The reason is that when the roller brush becomes very messy, its drying effect becomes uneven, and because some roller brush hairs stand up, the interference with the roller brush cover and other parts becomes larger, so the starting current will also be very large.

[0008] The solution provided in this application can not only make the structure more compact, but also improve the self-cleaning efficiency and effect, as follows.

[0009] First: In this application, the heat source used in both the washing stage and the drying stage is only one, which is an infrared heating device. Specifically, this patent does not require multiple heaters to achieve multi-functional self-cleaning. The advantage is that whether it is drying or self-cleaning heating, the control logic is simpler and there is no need to constantly switch different heating elements. It should be understood that the start-up of each heating element requires a large starting current and more time for preheating. The above problems can be completely avoided by using only one heat source. It saves switching time, preheating time of multiple heat sources, and combines the fast heating characteristics of infrared devices to make the overall efficiency of the entire self-cleaning process higher.

[0010] Second: This application makes cleaning more efficient through multiple structures and logical control. Specifically, after the water washing is completed, that is, in the spin-drying stage, the infrared heating device is controlled to start. Imagine that there is very little water on the base during the spin-drying stage (because the sewage will be sucked away after the water washing is completed), and at this time the roller brush is in contact with the transmission part, and the transmission part is in a high temperature state. For this reason, the roller brush can also iron the transmission part while spinning. The shape of the transmission part and the roller brush are adapted, both in an arc state. At this time, the roller brush can not only achieve faster drying through the ironing of the transmission part, but also ensure that the roller brush is flatter.

[0011] Third: Since the drying process is involved in the spin-drying stage, the roller brush can be dried while spinning. Specifically, in the subsequent drying stage, since the spin-drying stage has been started, the preheating and heating time are omitted, and the drying state can be directly entered. Secondly, since the heating is carried out in the spin-drying stage, part of the water will be evaporated due to the temperature during the spin-drying. Based on this, the solution of the present application significantly improves the overall efficiency of self-cleaning by intervening heating and ironing in the spin-drying stage, and the self-cleaning effect is also better.

[0012] Fourth: Since the heating method in the prior art uses hot air, the fan power is often very large. The heating method in this application mainly uses infrared heating, which is quieter and does not require a high-power fan to blow for drying. Based on this, the use of the above-mentioned infrared heating method can make the noise in the overall self-cleaning process smaller, thereby achieving the basic silent washing and silent drying functions.

[0013] Optionally, the infrared heating device includes a heat sink, and the heat sink is located below the infrared emitter; The base also includes a fan. In the spin-drying mode, the fan is controlled to turn on so as to blow the heat of the heat sink toward the roller brush.

[0014] It should be understood that the heat sink of the present application is used to absorb the extra light or heat dissipated by the infrared emitter, so as to prevent other parts of the base from being burned. Specifically, it is mainly used to absorb the heat dissipated under the infrared emitter, and a fan is set on this basis. The fan power here can be selected as a smaller power fan to dissipate the heat of the heat sink, and then dissipate the heat concentrated on the heat sink.

[0015] In other words, the heat dissipation of the infrared emitter is concentratedly absorbed by the heat sink, and then blown to the heat sink by the fan, so as to achieve the heat dissipation effect. The corresponding heat sink can also be made into dark colors, such as black, gray, etc.

[0016] At the same time, on this basis, a corresponding air duct is set in the base, and the fan is used to blow away the heat of the heat sink, and the outlet of the air duct is facing the roller brush. In this way, the fan, heat sink, infrared emitter, air duct, etc. are used together to achieve multiple heating of the roller brush and ensure that the base is not burned. Specifically, under this scheme, the roller brush has both direct heating by the infrared emitter and hot air heating by the heat sink, that is, multiple heating is achieved by using one set of devices. Compared with the heating scheme in the prior art, there are more heating methods and better heating effects.

[0017] Optionally, the cleaning device further comprises a detection device, and the self-cleaning method comprises: Controlling the cleaning device to perform a self-cleaning action before executing the spin-drying mode; The self-cleaning action includes: In response to the self-cleaning instruction, controlling the cleaning device to enter a first cleaning mode, the first cleaning mode comprising a first cleaning stage and a second cleaning stage; In the first cleaning mode, the infrared heating device is controlled to turn on, the water distributor is controlled to spray water, and the roller brush is controlled to rotate; After the cleaning device performs the first cleaning stage, the detection device is controlled to detect dirt on the roller brush, determine the state of the roller brush, and continue to perform the second cleaning stage; The roller brush states include a lightly soiled state, a medium soiled state, and a heavily soiled state.

[0018] In the present application, during the self-cleaning process, the self-cleaning instruction is directly responded to, and the self-cleaning state is directly entered according to the instruction, the control enters the first cleaning mode, and the first cleaning mode is divided into two stages. After the first cleaning stage is executed, the dirt detection action is started. Such a setting can ensure that cleaning equipment such as a floor scrubber can perform self-cleaning actions at the first time. If it is set to make a judgment after obtaining the self-cleaning instruction, then the floor scrubber must react for a period of time before it can really enter the self-cleaning mode. The reaction time is too slow, and the time from obtaining the instruction to the end of the self-cleaning execution is too long, and the user experience is too poor.

[0019] In other words, the self-cleaning method provided by the present application will execute the first cleaning mode as soon as possible regardless of the cleaning mode, and the first cleaning mode is configured as follows: the infrared heating device is turned on, the water divider sprays water, and the roller brush rotates. This ensures that the first cleaning mode can be heated by hot water. Such a setting at the initial stage of self-cleaning can help dissolve dirt as soon as possible, so as to prepare for different cleaning modes corresponding to different roller brush states later.

[0020] Optionally, in the first cleaning stage, the water distributor stops spraying water when the water spray volume reaches 45-55 mml; In the second cleaning stage, the water distributor stops spraying water when the water spray volume reaches 45-55 ml; After the water divider stops spraying water during the first cleaning phase, and before the water divider sprays water during the second cleaning phase, the suction device is controlled to perform a suction action.

[0021] Furthermore, the first cleaning mode is divided into two stages, and the water volume is also divided into two stages, and the water volume in each stage is controlled within 45-55ml. Specifically, for example, the duration of the first cleaning stage is set to 6s, and spraying water for 2s can meet the above requirements. Then, after spraying water for 2s, the water distributor is controlled to stop spraying water. The purpose of controlling the above water volume is as follows.

[0022] First: Since it is the initial stage, the current degree of dirtiness of the floor scrubber is not clear. Controlling the water volume can prevent water waste. At the same time, since the infrared transmitter has just been started, it takes a certain amount of time to heat up to the target temperature. Controlling the water volume can ensure that the water temperature can quickly reach a suitable temperature, such as 60°C.

[0023] Second: Since the first cleaning mode is divided into two stages, a certain amount of water is allocated to each stage to achieve multiple small-volume cleanings, which can also ensure that the cleaning effect is enhanced without wasting water.

[0024] Optionally, when the roller brush is in a lightly dirty state, the cleaning device is controlled to enter a spin-drying mode after the first cleaning mode ends; When the roller brush is in a medium dirty state, the cleaning device is controlled to enter a soaking mode after the first cleaning mode is finished, and then enters a spin-drying mode after the soaking mode is finished; The immersion washing mode includes controlling the infrared heating device to turn on, the water distributor to spray water, the roller brush to rotate, and the water spraying volume is between 70-90ml.

[0025] The above scheme introduces cleaning methods for lightly contaminated and moderately contaminated states. Specifically, when it is judged to be a lightly contaminated state, the current roller brush can complete cleaning after two stages of hot water cleaning in the first cleaning mode, that is, there is no need to waste resources or time on other cleaning, and the self-cleaning time can be further controlled and resource waste can be prevented.

[0026] If it is detected as a medium-contaminated state, after executing two stages of hot water cleaning in the first cleaning mode, it enters the immersion washing mode. The immersion washing mode is configured to spray a larger amount of water. The above water volume is controlled between 70-90ml to ensure that the bristles of the roller brush in contact with the base can be soaked. At the same time, the infrared heating device remains on, that is, in the medium-contaminated state, the two hot water cleaning stages of the first cleaning mode and the self-cleaning of the immersion washing mode are utilized to further ensure the cleaning effect of the roller brush.

[0027] Optionally, when the roller brush is in a heavy-dirt state, the cleaning device is controlled to enter a heavy-dirt cleaning mode after the first cleaning mode ends; The heavy dirt cleaning mode includes controlling the infrared heating device to turn on, the water distributor to spray water, the roller brush to rotate, and the water spraying volume is between 50-70ml, and the water temperature in the cleaning tank is controlled at 90-100°C.

[0028] When it is judged to be in a heavy dirt state, after executing the two hot water self-cleaning stages of the first cleaning mode, it enters high-temperature self-cleaning. At this time, the water spray volume is controlled at 50-70ml to ensure that the above water volume can be quickly heated to 90-100°C, and high temperature and large water volume are used to achieve high-temperature cleaning and dissolution, thereby ensuring the cleaning effect of the above roller brush.

[0029] In other words, the present application provides an intelligent cleaning method, which directly enters the first cleaning mode and is divided into two stages. When executing the second stage, the roller brush status is judged to determine the next cleaning action. This not only ensures the rapid implementation of self-cleaning, but also uses intelligent judgment to ensure the self-cleaning effect and provide the highest cleaning efficiency. At the same time, the infrared heating device runs through all stages of self-cleaning, further ensuring the cleaning effect.

[0030] According to a second aspect of an embodiment of the present disclosure, a self-cleaning method is provided, which is applied to a cleaning system, wherein the cleaning system comprises a cleaning device and a base, wherein the cleaning device comprises a body and a floor brush, wherein a roller brush and a water separator are arranged in the floor brush, and wherein a suction device is arranged in the body; The base is provided with a cleaning groove for accommodating the roller brush, and the base is provided with an infrared heating device, which includes an infrared emitter and a transmission member, and both are located below the roller brush; the self-cleaning method includes: In response to a drying instruction, the cleaning device is controlled to enter a drying mode; in the drying mode, the water separator is in a closed state, the roller brush rotates, and the infrared heating device is in a heating state; When the drying mode ends, controlling the infrared heating device to stop heating; Within a preset time after the infrared heating device stops heating, the roller brush is controlled to be in a rotating state.

[0031] The present application provides an infrared heating solution, which utilizes an infrared heating device throughout the entire process of roller brush cleaning, including the self-cleaning process as well as the spin-drying and drying stages. That is, a heating device is used to achieve the heating requirements of each stage, while also ensuring maximum drying efficiency and saving energy.

[0032] For example, in the above-mentioned drying stage, after the infrared heating device executes the preset time, the infrared heating device is directly controlled to stop heating, but the temperature on the transparent part is still very high at this time, so the residual heat can be used for further drying. In other words, in the prior art, the heating device often needs to be turned on for 30 minutes to achieve the effect of high-temperature drying. In this solution, the infrared heating device only needs to be turned on for 25 minutes, and then the residual temperature can be used to complete the heating and drying.

[0033] And in the residual heating state, the roller brush keeps rotating, and the roller brush bristles are attached to the transmissive part, so that the residual heat can be used for ironing, thereby ensuring that the roller brush bristles are in a flat attached state after drying. At the same time, the rotation of the roller brush can also prevent the roller brush bristles from being attached at one angle all the time, which will cause the roller brush bristles to be burned.

[0034] Optionally, controlling the roller brush to be in a rotating state includes: controlling the roller brush to rotate forward and reverse alternately.

[0035] The reverse rotation of the roller brush can turn up the bristles, and the heat can be more easily transferred to the inside of the roller brush, thereby improving the drying efficiency of the roller brush. The forward rotation of the roller brush can use the contact between the roller brush and the transmission part to iron the bristles of the roller brush, ensuring that the roller brush is smoother. Therefore, the alternating forward and reverse rotation process can improve the drying efficiency and drying effect on the basis of reducing the risk of the roller brush being burned. At the same time, the last action before the roller brush stops rotating can be controlled to be configured as forward rotation. At this time, the roller brush bristles are relatively soft, and the last action of forward rotation can ensure that the roller brush bristles are smoother.

[0036] Optionally, the infrared heating device further includes a heat sink and a reflective element; along the vertical direction, the reflective element and the transmissive element are respectively located on opposite sides of the infrared emitter, and the heat sink is located below the reflective element.

[0037] The function of the heat sink is as described above and will not be described again.

[0038] Optionally, the base further comprises a fan, ventilation holes located around the roller brush, and an air duct between the fan outlet and the ventilation holes, and at least the infrared emitter and the heat sink are located in the air duct; In the drying mode, the fan is controlled to be turned on, and the airflow blown out by the fan can flow to the ventilation hole through the air duct to blow the heat of the infrared emitter and the heat sink to the roller brush.

[0039] The ventilation hole is the outlet of the air duct in the aforementioned base. The ventilation hole faces the roller brush. The wind blown out by the fan flows to the ventilation hole through the air duct, and then blows to the roller brush from the ventilation hole. In this way, the fan, heat sink, infrared emitter, air duct, etc. are used in combination to achieve multiple heating of the roller brush, and it can also ensure that the base is not burned.

[0040] Optionally, the reflective element and the transmissive element are jointly arranged to form a chamber, and the infrared emitter is located in the chamber; the bottom of the reflective element has an opening communicating with the chamber, and the heat dissipation element is opposite to the opening.

[0041] The chamber can better concentrate the heat generated by the infrared emitter at the roller brush. For example, the surface of one side of the reflector forming the chamber is a downward concave curved surface, which can gather the reflected infrared rays and project them onto the roller brush. This reduces the loss of infrared rays outside the chamber and improves the utilization rate of infrared rays emitted by the infrared emitter.

[0042] The opening can reduce the barrier between the infrared emitter and the heat sink, so that the heat in the chamber is transferred to the heat sink more quickly, thereby improving the heat dissipation effect.

[0043] Optionally, the heat sink includes a heat sink base and at least one heat sink, wherein the heat sink is located on the heat sink base and faces the opening; when there are multiple heat sinks, the multiple heat sinks are evenly spaced along the length direction of the infrared emitter, wherein the length direction of the infrared emitter is parallel to the axis of the roller brush.

[0044] The heat dissipation base can not only increase the heat dissipation area, but also serve as a mounting carrier for the heat sink. The more heat sinks there are, the larger the heat dissipation surface is, and the more conducive to improving the heat dissipation effect.

[0045] The plurality of heat sinks are evenly distributed along the length direction of the infrared emitter, so that the heat at each location of the infrared emitter 220 can be dissipated through the heat sink, further improving the heat dissipation effect.

[0046] Optionally, the infrared heating device further comprises a fixing bracket, which is respectively connected to the base, the infrared emitter and the base, so that the infrared emitter and the heat sink are both connected to the base through the fixing bracket.

[0047] The fixing bracket can limit and fix the infrared emitter, which can effectively improve the reliability and firmness of the connection between the infrared emitter and the base. It can also effectively reduce or avoid shaking of the infrared emitter, thereby causing damage to the infrared emitter, helping to improve the protection of the infrared emitter and extend the service life of the infrared emitter.

[0048] Moreover, the infrared emitter and the heat sink are installed simultaneously by using the fixing bracket, which improves the utilization rate of the fixing bracket and helps to save the internal space of the base.

[0049] Optionally, a surface of the reflective member facing the infrared emitter is a downwardly concave curved surface, and the curved surface and the transmissive member are together arranged to form the cavity.

[0050] Optionally, the infrared heating device further comprises a shock absorbing pad, and the shock absorbing pad is located at the connection between the transmission element and the reflection element.

[0051] The shock-absorbing pad can absorb the vibration generated during the self-cleaning process, reducing or even avoiding damage to the infrared heating device caused by the rotation of the roller brush, the removal and placement of the cleaning equipment from the base, etc.

[0052] According to a third aspect of the embodiments of the present disclosure, a self-cleaning method is proposed. Applicable to a cleaning system, the cleaning system comprising a cleaning device and a base, the cleaning device comprising a body and a floor brush, the floor brush is provided with a roller brush and a water separator, and the body is provided with a suction device; The base is provided with a cleaning groove for accommodating the roller brush, and the base is provided with a detection device and an infrared heating device, and the infrared heating device includes an infrared emitter and a transmission member, and both are located below the roller brush; the self-cleaning method includes: In response to the self-cleaning instruction, the cleaning device is controlled to enter a first cleaning mode, wherein the first cleaning mode includes a first cleaning stage and a second cleaning stage; in the first cleaning mode, the infrared heating device is controlled to be turned on, the water separator is controlled to spray water, and the roller brush is controlled to rotate; After the cleaning device performs the first cleaning stage, the detection device is controlled to detect dirt on the roller brush, determine the state of the roller brush, and continue to perform the second cleaning stage; The roller brush states include a lightly soiled state, a medium soiled state, and a heavily soiled state.

[0053] In the present application, during the self-cleaning process, the self-cleaning instruction is directly responded to, and the self-cleaning state is directly entered according to the instruction, the control enters the first cleaning mode, and the first cleaning mode is divided into two stages. After the first cleaning stage is executed, the dirt detection action is started. Such a setting can ensure that cleaning equipment such as a floor scrubber can perform self-cleaning actions at the first time. If it is set to make a judgment after obtaining the self-cleaning instruction, then the floor scrubber must react for a period of time before it can really enter the self-cleaning mode. The reaction time is too slow, and the time from obtaining the instruction to the end of the self-cleaning execution is too long, and the user experience is too poor.

[0054] In other words, the self-cleaning method provided by the present application will execute the first cleaning mode as soon as possible regardless of the cleaning mode, and the first cleaning mode is configured as follows: the infrared heating device is turned on, the water divider sprays water, and the roller brush rotates. This ensures that the first cleaning mode can be heated by hot water. Such a setting at the initial stage of self-cleaning can help dissolve dirt as soon as possible, so as to prepare for different cleaning modes corresponding to different roller brush states later.

[0055] Optionally, before entering the first cleaning mode, the self-cleaning method further includes: A stall test is performed on the roller brush, wherein the stall test includes controlling the roller brush to rotate forward or reverse alternately, and the reversal angle of the roller brush is less than 360°.

[0056] The stall test can promptly determine whether the roller brush is stalled, and perform overcurrent protection on the roller brush motor to ensure safety during use.

[0057] During the reversal process, the reversal angle of the roller brush is less than 360°, which can reduce the entanglement and other dirt spitting out from the front of the roller brush, and the dirt can be brought to the dirt suction port of the floor brush, and then collected under the action of negative pressure. This further improves the cleaning effect of the dirt on the roller brush.

[0058] The alternating forward and reverse rotation of the roller brush is also beneficial to further improve the cleaning effect of the entangled objects. For example, when the roller brush motor drives the cleaning element to rotate forward, the scraper on the floor brush can pick up and cut the entangled objects. By rotating the roller brush reversely, the entangled objects tightened on the roller brush can be loosened. When the entangled objects are loosened, the roller brush can be rotated forward again to allow the scraper to pick up and cut the entangled objects again. In this way, the entangled objects can be better cleaned during the stall test by alternating forward and reverse rotation.

[0059] Optionally, the reversal angle of the roller brush is 280° to 340°, the starting point of the reversal angle is the contact point between the roller brush and the transmission member, and a vertical line between the contact point and the axis of the roller brush is perpendicular to a horizontal plane.

[0060] The roller brush reversal angle of 280° to 340° can better prevent dirt from being spit out from the front of the roller brush, and more dirt can be brought to the dirt suction port of the floor brush.

[0061] Specifically, most of the dirt in the prior art will appear on the roller brush cover, water divider, scraper and other positions. Reversal can be used to better clean the dirt in the above-mentioned positions. The contact position between the roller brush and the base is set to the starting point, and then the reversal angle of the roller brush is controlled to be between 280° and 340°. It can be ensured that the roller brush can be reversed to clean the above-mentioned positions. That is, controlling the reversal of 280° can ensure that the roller brush can clean at least the roller brush cover and other positions, thereby achieving the above-mentioned dirt cleaning. Setting 340° can ensure that the above-mentioned dirt will not be spit out by the roller brush, and at the same time the dirt can be moved to the above-mentioned dirt suction position, which not only ensures the cleaning effect, but also prevents the dirt from appearing in other positions.

[0062] Optionally, the performing a stall test on the roller brush comprises: After controlling the roller brush motor to drive the roller brush to rotate forward for a first preset time, controlling the roller brush motor to drive the roller brush to rotate reversely for a second preset time; In response to the roller brush being in forward rotation, the current of the roller brush motor being greater than or equal to a first current value, and / or in response to the roller brush being in reverse rotation, the current of the roller brush motor being greater than or equal to a second current value, it is determined that the roller brush is stalled; wherein the second current value is greater than the first current value.

[0063] The stall test can promptly determine whether the roller brush is stalled, and perform overcurrent protection on the roller brush motor to ensure safety during use.

[0064] Optionally, the self-cleaning method further comprises: If the roller brush is slightly dirty, the cleaning device is controlled to enter a spin-drying mode after the first cleaning mode ends; If the roller brush is in a medium or heavy dirty state, then at the end of the second cleaning stage, the cleaning device is controlled to enter a second cleaning mode; wherein, when the roller brush is in a medium dirty state, the temperature of the cleaning water in the second cleaning mode is lower than the temperature of the cleaning water in the second cleaning mode when the roller brush is in a heavy dirty state.

[0065] The above scheme introduces cleaning methods under light pollution state, medium pollution state and heavy pollution state. Specifically, when it is judged to be a light pollution state, the current roller brush can complete cleaning after two stages of hot water cleaning in the first cleaning mode and enter the spin-drying stage. That is, there is no need to waste resources or time on other cleaning, and the self-cleaning time can be further controlled and resource waste can be prevented.

[0066] If it is detected as a medium or heavy contamination state, after executing two stages of hot water cleaning in the first cleaning mode, the second cleaning mode is entered. The second cleaning mode is configured to have a larger water spray volume or a higher water temperature, or both, and the infrared heating device remains on, that is, in the medium or heavy contamination state, the two hot water cleaning stages of the first cleaning mode and the self-cleaning of the second cleaning mode are utilized, thereby further ensuring the cleaning effect of the roller brush.

[0067] Optionally, the method further comprises: In the second cleaning mode, the temperature of the cleaning water is controlled by providing different water volumes; wherein the water volume of the cleaning water is negatively correlated with the temperature of the cleaning water.

[0068] When other conditions are the same or approximately the same (for example, the infrared transmitter power remains unchanged, the heating time is equal or not much different), the larger the amount of water used for cleaning, the lower the water temperature; conversely, the smaller the amount of water used for cleaning, the higher the water temperature. There is a negative correlation between water volume and water temperature. By controlling the water volume, the water temperature can be controlled, which is simpler and more convenient.

[0069] Optionally, the second cleaning mode includes a soaking and washing mode, and if the roller brush is in a medium-dirty state, the cleaning device is controlled to enter the soaking and washing mode after the first cleaning mode ends, and enters the spin-drying mode after the soaking and washing mode is completed; The immersion washing mode includes controlling the infrared heating device to turn on, the water distributor to spray water, the roller brush to rotate, and the water spraying volume is between 70-90 ml.

[0070] The beneficial effects of soaking washing are described above and will not be repeated here.

[0071] Optionally, the second cleaning mode includes a heavy dirt cleaning mode; If the roller brush is in a heavy-dirt state, controlling the cleaning device to enter the heavy-dirt cleaning mode after the first cleaning mode ends; The heavy dirt cleaning mode includes controlling the infrared heating device to turn on, the water distributor to spray water, the roller brush to rotate, and the water spraying volume is between 50-70ml, and the water temperature in the cleaning tank is controlled at 90-100°.

[0072] The beneficial effects of the heavy dirt cleaning mode are described above and will not be repeated here.

[0073] Optionally, in the first cleaning stage, the water distributor stops spraying water when the water spray volume reaches 45-55 mml; In the second cleaning stage, the water distributor stops spraying water when the water spray volume reaches 45-55 ml; After the water distributor stops spraying water during the first cleaning phase, and before the water distributor sprays water during the second cleaning phase, the suction device is controlled to perform a suction action. The beneficial effects here refer to the above and will not be described again. Optionally, the self-cleaning method also includes: When the drying mode ends, controlling the infrared heating device to stop heating; Within a preset time after the infrared heating device stops heating, the roller brush is controlled to be in a rotating state. The beneficial effects here refer to the above and will not be described again.

[0074] Optionally, the base further includes a temperature detector, the reflective member and the transmissive member are jointly arranged to form a chamber, the infrared emitter and the temperature detector are both located in the chamber; the temperature detector infrared emitter is used to detect the air temperature adjacent to the infrared emitter.

[0075] The temperature detector detects the lower air temperature instead of directly detecting the higher temperature of the infrared emitter or the transmission component temperature, which is beneficial to reduce the damage of the temperature detector.

[0076] Optionally, the self-cleaning method further comprises: The working parameters of the infrared emitter are controlled so that the temperature detected by the temperature detector is 90° C.-120° C.

[0077] When it is lower than 90℃, the temperature of the transmissive component is difficult to heat the liquid on it to a higher temperature (such as 100℃), while too high temperature, such as higher than 120℃, will cause the temperature to rise too high, thereby forming too much steam and too little water. 90℃-120℃ can ensure that the amount of water retained on the transmissive component during the cleaning phase is appropriate, and the amount of steam formed is appropriate. That is to say, within this temperature range, it can not only dissolve dirt at high temperature, but also achieve a certain amount of water to form a soaking effect, and can also use the high temperature of steam for sterilization, which can at least effectively improve the cleaning effect of the cleaning phase.

[0078] According to a fourth aspect of an embodiment of the present disclosure, a cleaning system is provided, characterized in that the cleaning system comprises a cleaning device, a base and a controller; The controller is used to execute the self-cleaning method as described in any embodiment of the first aspect, the second aspect or the third aspect.

[0079] The cleaning system provided in the embodiment of the present application has the same technical effect as the aforementioned self-cleaning method, and will not be described again here. BRIEF DESCRIPTION OF THE DRAWINGS

[0082] In order to make the technical solutions and beneficial effects of the present invention more clearly understandable, the following is a detailed description by listing specific embodiments. The drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application belongs.

[0084] In each embodiment of the present disclosure, unless otherwise specified or there is a logical conflict, the terms and / or descriptions between the embodiments are consistent and can be referenced to each other, and the technical features in different embodiments can be combined to form a new embodiment based on their internal logical relationships.

[0085] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. Example 1

[0086] This embodiment provides a cleaning system. Figures 1 to 7As shown, the cleaning system is introduced in detail.

[0087] like Figures 1 to 3 As shown, the cleaning system 10 includes a cleaning device 100 and a base 200. The cleaning device 100 may include a floor brush. When working, the cleaning device 100 moves on the surface to be cleaned, and the floor brush contacts and rubs with the surface to be cleaned to clean the surface.

[0088] refer to Figure 1 The floor brush 100 may include a housing, a roller brush 110 and a running wheel 102. The housing is the main supporting structure of the floor brush 100, and the roller brush 110 and the running wheel 102 may be both installed in the housing 103. For example, the housing 103 may have a receiving cavity, the roller brush 110 may be located in the receiving cavity of the housing 103, and the roller brush 110 may rotate around the axial direction of the roller brush 110 itself.

[0089] When the cleaning device is cleaning, the roller brush 110 contacts the surface to be cleaned, and the roller brush motor installed in the roller brush 110 drives the roller brush 110 to rotate at a high speed, so that the roller brush 110 can make friction contact with the surface to be cleaned to clean the surface. The walking wheel 102 contacts the surface to be cleaned and rolls along the surface to be cleaned to assist the cleaning device to walk on the surface to be cleaned, which can improve the stability of the floor brush 100 walking on the surface to be cleaned.

[0090] like Figure 2 and Figure 3 As shown, a cleaning tank 211 for accommodating the roller brush 110 of the cleaning device 100 is provided on the base 200 . When the cleaning device 100 is docked on the base 200 , the cleaning device 100 can perform self-cleaning. During the self-cleaning process, the roller brush 110 is cleaned and dried in the cleaning tank 211 .

[0091] The cleaning system further comprises an infrared heating device, which is located in the base 200. Figures 4 to 6 As shown, the infrared heating device includes a transmission member 230 and an infrared emitter 220 . The transmission member 230 and the infrared emitter 220 are both located below the roller brush 110 , and the transmission member 230 can contact the roller brush 110 .

[0092] The transmission member 230 can transmit infrared rays. The infrared emitter 220 can be used to emit infrared rays, and at least part of the infrared heat emitted by the infrared emitter 220 can be radiated to the roller brush 110 through the transmission member 230 .

[0093] After the infrared emitter 220 is turned on, a relatively high temperature can be formed on the transmission member 230. The transmission member 230 can iron the roller brush 110 by contacting the roller brush 110, thereby further improving the drying efficiency and making the bristles smoother.

[0094] In one embodiment, the transmissive member 230 may be a glass panel, the temperature of the back side of which may reach 200-280° C., so that the temperature achievable is higher than that of hot air or ordinary heating methods in the prior art, and ironing can be achieved by using high temperature in combination with a roller brush.

[0095] The infrared rays generated by the infrared emitter 220 can quickly pass through the transmission part 230 and penetrate the material surface of the roller brush 110, and directly transfer the energy to the interior and surface of the roller brush 110, which can effectively speed up the drying speed of the roller brush 110 and improve the drying efficiency of the roller brush 110.

[0096] Moreover, infrared rays can provide uniform heat distribution, which can effectively reduce or avoid the situation where the roller brush 110 is locally overheated or not dried, and can effectively improve the drying quality.

[0097] In addition, compared with traditional hot air drying, the infrared emitter 220 provided in the embodiment of the present application can transfer heat directly to the surface and interior of the roller brush 110, and its heat conduction loss is low, which has a better energy-saving effect.

[0098] In some optional embodiments, the transparent member 230 may constitute at least a portion of the bottom of the cleaning tank 211 .

[0099] For example, the transmissive member 230 may be connected to the base 200 , and in the vertical direction (direction substantially perpendicular to the horizontal plane), the transmissive member 230 may be located between the infrared heater and the roller brush 110 , and the roller brush may maintain contact with the transmissive member 230 during rolling.

[0100] In some optional embodiments, such as Figure 5 As shown, the base 200 may have a receiving space 213, and the infrared heating device is at least partially located in the receiving space 213. For example, the infrared emitter 220 and the fan 250 may all be located in the receiving space 213, so that the base 200 can install and fix the above-mentioned structural components. The receiving space 213 may be specifically defined and formed by the base shell 210.

[0101] In some optional embodiments, the infrared emitter 220 can be a carbon fiber heating tube. When the infrared emitter 220 is turned on, current can be transmitted to the carbon fiber heating tube. The current passes through the carbon fiber heating tube, causing the molecules inside the carbon fiber heating tube to move, thereby converting electrical energy into heat energy. The heat energy can be quickly and evenly radiated to the surrounding of the roller brush 110 in the form of infrared radiation to dry the roller brush 110.

[0102] In some optional embodiments, the wavelength band of infrared rays may be between 1.5 μm and 15 μm. The light in this wavelength band may be effectively absorbed by organic matter, and the infrared radiation intensity may be increased by more than 30%, thereby having a stronger infrared radiation effect.

[0103] The transparent component 230 can isolate the infrared emitter 220 and the roller brush 110 from each other, thereby reducing or avoiding direct contact between the roller brush 110 and the infrared emitter 220, preventing water stains, dirt, etc. on the roller brush 110 from contaminating the infrared emitter 220, reducing the risk of damage to the infrared emitter 220 due to water stains or dirt contamination, and helping to improve the protection of the infrared emitter 220.

[0104] By way of example, the transmissive member 230 may be a glass plate or a light-transmitting plastic plate.

[0105] For example, the transmission member 230 may be in the shape of a convex lens, and the convex lens-shaped transmission member 230 may gather the light passing through, so that the infrared rays passing through the transmission member 230 may be gathered, and thus be projected on the roller brush 110. This may effectively increase the amount of infrared rays projected on the roller brush 110, reduce the waste of infrared rays, and thus effectively improve the utilization rate of infrared rays, and enhance the drying efficiency of the roller brush 110 by the infrared heating device.

[0106] In some optional embodiments, such as Figures 4 to 6 As shown, the infrared heating device may further include a reflector 240. In the vertical direction, the reflector 240 and the transmission member 230 are respectively located on opposite sides of the infrared emitter 220, and the heat sink 290 is located below the reflector 240. At least part of the infrared rays may be reflected to the transmission member 230 by the reflector 240, and radiated to the roller brush 110 by the transmission member 230. For example, the side of the reflector 240 facing the infrared emitter 220 may be a mirror surface, so that the infrared rays projected on the mirror surface of the reflector 240 may be reflected.

[0107] For example, the infrared rays generated by the side of the infrared emitter 220 facing the roller brush 110 can be projected onto the transmission member 230 and onto the roller brush 110 through the transmission member 230. The infrared rays generated by the side of the infrared emitter 220 facing away from the roller brush 110 can be projected onto the reflection member 240 and reflected onto the transmission member 230 through the reflection member 240, and then projected onto the roller brush 110 through the transmission member 230, so as to dry the roller brush 110.

[0108] By reflecting the infrared rays by the reflector 240, the infrared rays generated by the side of the infrared emitter 220 facing away from the roller brush 110 can also be projected onto the roller brush 110 to dry the roller brush 110. This can effectively increase the amount of infrared rays projected onto the roller brush 110, and effectively reduce or avoid the waste of infrared rays. This effectively improves the utilization rate of infrared rays, and improves the cleaning and drying efficiency of the base 200 on the roller brush 110.

[0109] In some optional embodiments, the infrared heating device further includes a heat sink 290, which is located below the infrared emitter 220. The heat sink 290 can absorb part of the energy of the infrared emitter 220, reduce the temperature near the infrared emitter 220, effectively ensure the service life of the base parts, and avoid risks caused by excessive heat concentration.

[0110] Exemplarily, the length of the heat sink 290 may be approximately equal to the length of the infrared emitter 220, so as to improve the heat dissipation effect at different positions of the infrared emitter 220. In order to further improve the heat dissipation effect, the heat sink 290 may optionally include a plurality of Figure 7 As shown in the heat sink 291 , a plurality of heat sinks 291 are evenly spaced apart along the length direction of the infrared emitter 220 .

[0111] In some optional embodiments, the reflective member 240 and the transmissive member 230 are jointly arranged to form a chamber 241 , and the infrared emitter 220 is located in the chamber 241 ; the reflective member 240 has an opening 242 at the bottom communicating with the chamber 241 , and the heat dissipation member 290 is opposite to the opening 242 .

[0112] The chamber can better concentrate the heat generated by the infrared emitter at the roller brush. For example, the surface of one side of the reflector forming the chamber is a downwardly concave curved surface (described in detail below). The curved surface can gather the reflected infrared rays and project them onto the roller brush 110. This reduces the loss of infrared rays outside the chamber and improves the utilization rate of infrared rays emitted by the infrared emitter.

[0113] The opening 242 can reduce the barrier between the infrared emitter 220 and the heat sink 290 , so that the heat in the chamber 241 can be transferred to the heat sink 290 more quickly, thereby improving the heat dissipation effect.

[0114] In some optional embodiments, the heat sink 290 includes a heat sink base 292 and a plurality of heat sinks 291, and the heat sinks 291 are located on the heat sink base 292 and face the opening 242. The heat generated by the infrared emitter 220 can be transferred to the heat sink 291 through the opening 242, and can also be transferred to the heat sink base 292 to improve the heat dissipation effect.

[0115] The heat dissipation base 292 can not only increase the heat dissipation area, but also serve as a mounting carrier for the heat dissipation fins 291. The more the number of heat dissipation fins 291 is, the larger the heat dissipation surface is, and the more conducive to improving the heat dissipation effect is.

[0116] The heat dissipation base 292 can not only increase the heat dissipation area, but also serve as a mounting carrier for the heat dissipation fins 291. The more the number of heat dissipation fins 291 is, the larger the heat dissipation surface is, and the more conducive to improving the heat dissipation effect is.

[0117] The plurality of heat sinks 291 are evenly spaced along the length direction of the infrared emitter 220, wherein the length direction of the infrared emitter 220 is parallel to the axis of the roller brush 110. In this way, the heat of each part of the infrared emitter 220 can be dissipated through the heat sink 290, further improving the heat dissipation effect.

[0118] Without limitation, the number of the heat sink 291 can be one, two, three or more. Generally, the more the number of the heat sink 291 is, the better the heat dissipation effect is.

[0119] In some optional embodiments, the infrared heating device also includes a fixed bracket 280, which is respectively connected to the base 200, the infrared emitter 220 and the heat dissipation base 292, so that the infrared emitter 220 and the heat dissipation element 290 are both connected to the base 200 through the fixed bracket 280.

[0120] The fixing bracket 280 can limit and fix the infrared emitter 220, which can effectively improve the reliability and firmness of the connection between the infrared emitter 220 and the base 200. In addition, it can effectively reduce or avoid the shaking of the infrared emitter 220, thereby damaging the infrared emitter 220, which helps to improve the protection of the infrared emitter 220 and extend the service life of the infrared emitter 220.

[0121] Moreover, the fixing bracket 280 is used to simultaneously install the infrared emitter 220 and the heat sink 290 , thereby improving the utilization rate of the fixing bracket 280 and helping to save the internal space of the base 200 .

[0122] For example, see Figure 5 As shown, the surface of the reflective member 240 facing the infrared emitter 220 is a downwardly concave curved surface, and the curved surface and the transmissive member together enclose a chamber 241 .

[0123] The curved surface can gather the reflected infrared rays during the process of reflecting the infrared rays, so that the reflected infrared rays can be gathered and concentrated on the roller brush 110, which can effectively reduce or avoid the outward heat dissipation of the infrared rays and improve the utilization rate of the infrared rays, thereby effectively improving the heating and drying efficiency of the infrared heater.

[0124] For example, the longitudinal cross-section of the reflector 240 may be roughly designed to be an ellipse (eg Figure 6As shown in the figure, the infrared emitter 220 is located at a focus F1 of the elliptical reflector 240, and can be used to heat the water for cleaning the roller brush during self-cleaning, thereby achieving high-temperature hot water cleaning of the roller brush; the transmission member 230 located above the radiation source absorbs a portion of the radiation while transmitting the infrared light, and this portion of the radiation energy can heat the light-transmitting parts. During the drying process of the roller brush 110, the light-transmitting parts with a relatively high temperature can heat the roller brush. The fact that the roller brush is ironed at a high temperature can improve the drying efficiency of the roller brush while effectively saving waste.

[0125] For example, Figure 7 As shown, the reflective member 240 has an opening 242 at the bottom, and the heat dissipation member 290 is located below the opening 242 to absorb the heat generated by the infrared emitter 220 thereon through the opening 242 .

[0126] The reflective element 240 and the transmissive element 230 may be directly connected, or, as Figure 6 As shown, the infrared heating device further includes a shock absorbing pad 260, which is located at the connection between the transmission member 230 and the reflection member 240. The transmission member 230 is connected to the reflection member 240 through the shock absorbing pad 260, and the shock absorbing pad 260 can absorb vibration energy, effectively preventing the vibration from damaging the transmission member 230 and the infrared emitter 220.

[0127] See also Figure 4 and Figure 5 As shown, the base 200 may include a fan 250 located in the accommodating space 213, and the fan 250 has a blowing port, and the wind flow blown out through the blowing port can pass through the infrared emitter 220 and the heat sink 290. If the infrared emitter 220 is in the on state, the fan 250 can transfer the infrared heat emitted by the infrared emitter 220 and the heat conducted by the heat sink 290 to the roller brush 110. If the infrared emitter 220 is in the off state, the fan 250 can also transfer the residual heat of the infrared emitter 220 and the heat sink 290 to the roller brush 110.

[0128] like Figure 3 As shown, the base 200 further includes a ventilation hole 271 located on the periphery of the roller brush 110, and an air duct 270 (such as Figure 4As shown in the figure, at least the infrared emitter 220 and the heat sink 290 are located in the air duct 270. The air duct assembly of the base 200 defines the air duct, and the air flow blown out of the air outlet of the fan 250 can drive the air flow around the infrared emitter 220 and the heat sink 290, which can not only transport the heat generated by the infrared emitter 220 to the roller brush 110, but also take away the heat absorbed by the heat sink 290 and transport it to the roller brush 110, further improving the drying effect of the roller brush 110. In addition, the air blown out of the air outlet can also reduce the temperature near the infrared emitter 220 and the heat sink 290, thereby improving the heat dissipation effect.

[0129] See also Figure 6 As shown, in some optional embodiments, the infrared heating device further includes a temperature detector 202, which can detect the air temperature near the infrared emitter 220. The working parameters of the infrared emitter 220 can be adjusted in time according to the temperature of the temperature detector 202 to keep the water and steam in the cleaning tank 211 appropriate and ensure the cleaning effect of the roller brush 110. The temperature detector 202 detects the lower air temperature instead of directly detecting the higher temperature infrared emitter or the temperature of the transmission member 230, which is conducive to reducing the damage of the temperature detector 202.

[0130] Exemplarily, the temperature detector 202 is a NTC (Negative Temperature Coefficient Sensor), but is not limited thereto.

[0131] refer to Figure 6 The temperature detector 202 is at least partially located in the chamber 241 , and the infrared emitter 220 is also located in the chamber 241 , so that the temperature detector 202 can measure the temperature of the space near the infrared emitter 220 .

[0132] Exemplarily, the temperature detector 202 may also be fixed on the fixing bracket 280, or the temperature detector may be fixed in the base through other brackets.

[0133] The number of infrared emitters 220 may be one, two, three or more.

[0134] refer to Figure 1 As shown, the cleaning equipment may further include a clean water tank 101, which may provide cleaning liquid (including but not limited to cleaning water for cleaning the roller brush in the cleaning tank during the self-cleaning process) to the roller brush 110 to soak the roller brush 110, so that the roller brush 110 may soak the stains on the surface to be cleaned during the cleaning process, thereby reducing the adhesion of the stains and making it easier to clean the stains from the surface to be cleaned.

[0135] Along the moving direction of the floor brush 100, the roller brush 110 can be installed at the front end of the housing, and the running wheel 102 can be installed at the rear end of the housing. This makes it easy to control the moving direction of the floor brush 100, which is conducive to maintaining the balance of the floor brush 100 during the moving process. In addition, the roller brush 110 preferentially contacts the surface to be cleaned, and there is no obstruction in front of the roller brush 110, which is conducive to the roller brush 110 cleaning the surface to be cleaned.

[0136] The cleaning device may further include a body, and the floor brush 100 may be rotatably connected to the bottom of the body. During the cleaning process, the user may hold the body in hand and swing the body to rotate the floor brush 100 relative to the body, so that the floor brush 100 can move to different areas (for example, under a table, under a cabinet, etc.), so that the floor brush 100 can clean different areas.

[0137] The machine body may be equipped with components such as a clean water tank 101 and a dirty water tank. The clean water tank 101 is used to hold cleaning liquid. When the cleaning device is working, the cleaning liquid in the clean water tank 101 is sprayed on the floor brush 100 or the surface to be cleaned in front of the floor brush 100, so as to cooperate with the floor brush 100 to clean the surface to be cleaned. The dirty water on the surface to be cleaned (together with foreign matter such as particles and hair) is sucked into the dirty water tank, thereby completing the cleaning process.

[0138] After the cleaning device is put back into the base, auxiliary operations such as self-cleaning and charging of the cleaning device are realized.

[0139] The execution subject of the embodiment of the present application may be a controller set in the cleaning device, or a controller set in the base, or the execution subject may also be a server corresponding to the cleaning device and the base. The server is located in the cloud, connected to the cleaning device through the network, and sends control instructions to the cleaning device and the base, or forwards the control instructions sent by the user through a terminal device (such as a mobile phone, a wearable device or a computer, etc.) to the cleaning device and the base, etc.

[0140] The controller may include a microcontroller unit (MCU). Of course, the controller may also include other devices that can have control functions.

[0141] For example, Figure 5 As shown, the base 200 has a signal input and output interface 201. When the cleaning device 100 is placed on the base 200, the signal interface of the cleaning device 100 is electrically connected to the signal input and output interface 201 of the base 200. The user can operate the self-cleaning button on the cleaning device 100 to send a self-cleaning instruction to the controller. The controller turns on the infrared transmitter based on the self-cleaning instruction, and controls the corresponding components on the cleaning device and the base to perform a self-cleaning action.

[0142] The following will be combined with the attached Figures 7 to 10 , taking the execution subject as a controller in a cleaning device as an example, the self-cleaning method of an embodiment of the present application is explained. Example 2

[0143] The self-cleaning method provided in this embodiment is applied to the cleaning system in any implementation of the aforementioned embodiment 1, and the method includes: like Figure 8 As shown, step S10, in response to the spin-drying instruction, controls the cleaning device to enter the spin-drying mode; in the spin-drying mode, the water separator is in a closed state, and the roller brush rotates; and in the spin-drying mode, the infrared heating device is in a heating state, and the roller brush contacts the transmissive member, so that the roller brush can be ironed by the transmissive member while being spun dry.

[0144] The self-cleaning process of the embodiment of the present application includes: washing, spinning and drying stages.

[0145] The spin-drying instruction can be an instruction carried in the self-cleaning instruction. At this time, the spin-drying stage can be entered after the water washing is completed. In addition, the spin-drying instruction can also be a separate instruction independent of the self-cleaning instruction.

[0146] Current floor scrubbers often perform self-cleaning after cleaning, and the existing self-cleaning often takes a long time. They usually use PTC or heating wires to directly heat hot water to achieve hot water cleaning. High-end machines will also add a set of heating wires to heat the air for drying. For this reason, common floor scrubbers use two heat sources to achieve hot water heating and drying.

[0147] And the drying method mainly adopts hot air drying method. Therefore, the roller brush hairs are in a messy state after drying. The roller brush in such a state will cause uneven moisture in the next cleaning. In addition, since some roller brush hairs stand up, the interference with parts such as the roller brush cover becomes larger, so the starting current will also be very large.

[0148] The solution provided in the embodiment of the present application can not only make the structure more compact, but also improve the self-cleaning efficiency and effect, as follows.

[0149] First: In the embodiments of the present application, the heat source used in both the washing stage and the drying stage is only one, which is an infrared heating device. Specifically, the present patent does not require multiple heaters to achieve multi-functional self-cleaning. The advantage is that whether it is drying or self-cleaning heating, the control logic is simpler and there is no need to constantly switch different heating elements. It should be understood that the start-up of each heating element requires a large starting current and more time for preheating. The above problems can be completely avoided by using only one heat source. It saves switching time, preheating time of multiple heat sources, and combines the fast heating characteristics of infrared devices to make the overall efficiency of the entire self-cleaning process higher.

[0150] Second: The embodiment of the present application makes the cleaning efficiency higher through multiple structures and logical control. Specifically, after the water washing is completed, that is, in the spin-drying stage, the infrared heating device is controlled to start. Imagine that there is very little water on the base during the spin-drying stage (because the sewage will be sucked away after the water washing is completed), and at this time the roller brush is in contact with the transmission part, and the transmission part is in a high temperature state. Therefore, the roller brush can also iron the transmission part while spinning. The shape of the transmission part and the roller brush are adapted, both in an arc state. At this time, the roller brush can achieve faster drying through the ironing of the transmission part, and at the same time ensure that the roller brush is flatter.

[0151] Third: Since the drying process is involved in the spin-drying stage, the roller brush can be dried while spinning. Specifically, in the subsequent drying stage, since the spin-drying stage has been started, the preheating and heating time are omitted, and the drying state can be directly entered. Secondly, since the heating is carried out in the spin-drying stage, part of the water will be evaporated due to the temperature during the spin-drying. Based on this, the solution of the present application significantly improves the overall efficiency of self-cleaning by intervening heating and ironing in the spin-drying stage, and the self-cleaning effect is also better.

[0152] Fourth: Since the heating method in the prior art uses hot air, the fan power is often very large. The heating method in this application mainly uses infrared heating, which is quieter and does not require a high-power fan to blow for drying. Based on this, the use of the above-mentioned infrared heating method can make the noise in the overall self-cleaning process smaller, thereby achieving the basic silent washing and silent drying functions.

[0153] In some optional embodiments, the infrared heating device includes the aforementioned heat sink, which is located below the infrared emitter; the base also includes the aforementioned fan; the self-cleaning method includes: in the spin-drying mode, controlling the fan to turn on to blow the heat from the heat sink toward the roller brush.

[0154] It should be understood that the heat sink of the embodiment of the present application is used to absorb the extra light or heat dissipated by the infrared emitter, so as to prevent other parts of the base from being damaged by burns. Specifically, it is mainly used to absorb the heat dissipated under the infrared emitter, and a fan is set on this basis. The fan power here can be selected as a smaller power fan to dissipate the heat of the heat sink, and then dissipate the heat concentrated on the heat sink.

[0155] In other words, the heat dissipation of the infrared emitter is concentratedly absorbed by the heat sink, and then blown to the heat sink by the fan, so as to achieve the heat dissipation effect. The corresponding heat sink can also be made into dark colors, such as black, gray, etc.

[0156] At the same time, on this basis, a corresponding air duct is set in the base, and the fan is used to blow away the heat of the heat sink, and the outlet of the air duct is facing the roller brush. In this way, the fan, heat sink, infrared emitter, air duct, etc. are used together to achieve multiple heating of the roller brush and ensure that the base is not burned. Specifically, under this scheme, the roller brush has both direct heating by the infrared emitter and hot air heating by the heat sink, that is, multiple heating is achieved by using one set of devices. Compared with the heating scheme in the prior art, there are more heating methods and better heating effects.

[0157] In some optional embodiments, the cleaning device further comprises a detection device, and the self-cleaning method comprises: controlling the cleaning device to perform a self-cleaning action before executing the spin-drying mode; Self-cleaning actions include: In response to the self-cleaning instruction, controlling the cleaning device to enter a first cleaning mode, the first cleaning mode comprising a first cleaning stage and a second cleaning stage; In the first cleaning mode, the infrared heating device is controlled to turn on, the water distributor performs water spraying, and the roller brush rotates; After the cleaning device executes the first cleaning stage, the control detection device detects dirt on the roller brush, determines the state of the roller brush, and continues to execute the second cleaning stage; wherein the roller brush state includes a lightly dirty state, a medium dirty state, and a heavily dirty state.

[0158] In the embodiment of the present application, during the self-cleaning process, the self-cleaning instruction is directly responded to, and the self-cleaning state is directly entered according to the instruction, the control enters the first cleaning mode, and the first cleaning mode is divided into two stages. After the first cleaning stage is executed, the dirt detection action is started. Such a setting can ensure that the cleaning equipment, such as a floor scrubber, can perform the self-cleaning action at the first time. If it is set to make a judgment after obtaining the self-cleaning instruction, then the floor scrubber must react for a period of time before it can really enter the self-cleaning mode. The reaction time is too slow, and the time from obtaining the instruction to the end of the self-cleaning execution is too long, and the user experience is too poor.

[0159] In other words, the self-cleaning method provided by the present application will execute the first cleaning mode as soon as possible regardless of the cleaning mode, and the first cleaning mode is configured as follows: the infrared heating device is turned on, the water divider sprays water, and the roller brush rotates. This ensures that the first cleaning mode can be heated by hot water. Such a setting at the initial stage of self-cleaning can help dissolve dirt as soon as possible, so as to prepare for different cleaning modes corresponding to different roller brush states later.

[0160] The detection device includes but is not limited to a color sensor, such as an RGB dirt detector.

[0161] RGB dirt detector refers to a device with color system (Red Green Blue, RGB) detection function.

[0162] The RGB dirt detector can accurately capture color information, brightness information, etc., making it easier to distinguish stains from other environmental information, thereby improving the accuracy of stain recognition. It can also distinguish different degrees of dirt based on color information, brightness information, etc., thereby improving the accuracy of identifying different degrees of dirt.

[0163] In some optional embodiments, in the first cleaning stage, the water distributor stops spraying water when the water spray volume reaches 45-55 mml; In the second cleaning stage, stop spraying water when the water dispenser sprays 45-55ml of water; After the water distributor stops spraying water during the first cleaning phase, and before the water distributor sprays water during the second cleaning phase, the suction device is controlled to perform a suction action.

[0164] Furthermore, the first cleaning mode is divided into two stages, and the water volume is also divided into two stages, and it is ensured that the water volume in each stage is controlled within 45-55 ml.

[0165] The water volume can be controlled by controlling the water distributor spraying time. Generally, the water spraying time is positively correlated with the water volume, that is, the longer the water spraying time, the greater the water volume. For example, the duration of the first cleaning stage is set to 6s, and the water spraying for 2s can meet the above requirements. Then, the water distributor is controlled to stop spraying after 2s of water spraying. The purpose of controlling the above water volume is as follows.

[0166] First: Since it is the initial stage, the current degree of dirtiness of the floor scrubber is not clear. Controlling the water volume can prevent water waste. At the same time, since the infrared transmitter has just been started, it takes a certain amount of time to heat up to the target temperature. Controlling the water volume can ensure that the water temperature can quickly reach a suitable temperature, such as 60°C.

[0167] Second: Since the first cleaning mode is divided into two stages, a certain amount of water is allocated to each stage to achieve multiple small-volume cleanings, which can also ensure that the cleaning effect is enhanced without wasting water.

[0168] The amount of water in the first cleaning phase and the second cleaning phase may be equal or approximately equal.

[0169] For example: the water volume in the first cleaning stage is 45ml, 50ml or 55ml, and the water volume in the second cleaning stage is 45ml, 50ml or 55ml.

[0170] In some optional embodiments, when the roller brush is in a lightly dirty state, the cleaning device is controlled to enter a spin-drying mode after the first cleaning mode ends; When the roller brush is in a medium dirty state, the cleaning device is controlled to enter a soaking mode after the first cleaning mode is completed, and then enters a spin-drying mode after the soaking mode is completed; The immersion washing mode includes controlling the infrared heating device to turn on, the water distributor to spray water, the roller brush to rotate, and the water spray volume is between 70-90ml.

[0171] The above scheme introduces cleaning methods for lightly contaminated and moderately contaminated states. Specifically, when it is judged to be a lightly contaminated state, the current roller brush can complete cleaning after two stages of hot water cleaning in the first cleaning mode, that is, there is no need to waste resources or time on other cleaning, and the self-cleaning time can be further controlled and resource waste can be prevented.

[0172] If it is detected as a medium-contaminated state, after executing two stages of hot water cleaning in the first cleaning mode, it enters the immersion washing mode. The immersion washing mode is configured to spray a larger amount of water, and the above-mentioned water volume is controlled to be between 70-90ml (specifically, the water volume can be 70ml, 80ml or 90ml), to ensure that the bristles of the roller brush in contact with the base can be soaked, and the infrared heating device remains on, that is, in the medium-contaminated state, the two hot water cleaning stages of the first cleaning mode and the self-cleaning of the immersion washing mode are utilized, which further ensures the cleaning effect of the roller brush.

[0173] In some optional embodiments, when the roller brush is in a heavy dirt state, the cleaning device is controlled to enter a heavy dirt cleaning mode after the first cleaning mode ends; the heavy dirt cleaning mode includes controlling the infrared heating device to turn on, the water divider to spray water, the roller brush to rotate, and the water spraying volume is between 50-70ml, and the water temperature in the cleaning tank is controlled at 90-100°.

[0174] When it is judged to be in a heavy dirt state, after executing the two hot water self-cleaning stages of the first cleaning mode, it enters high-temperature self-cleaning (ie heavy dirt cleaning mode). At this time, the water spray volume is controlled at 50-70ml to ensure that the above water volume can be quickly heated to 90-100°, and high temperature and large water volume are used to achieve high-temperature cleaning and dissolution, thereby ensuring the cleaning effect of the above roller brush.

[0175] In other words, the present application provides an intelligent cleaning method, which directly enters the first cleaning mode and is divided into two stages. When executing the second stage, the roller brush status is judged to determine the next cleaning action. This not only ensures the rapid implementation of self-cleaning, but also uses intelligent judgment to ensure the self-cleaning effect and provide the highest cleaning efficiency. At the same time, the infrared heating device runs through all stages of self-cleaning, further ensuring the cleaning effect.

[0176] The water spray volume of the heavy dirt cleaning mode can be 50ml, 60ml or 70ml, and the water temperature can be 90°C or 100°C, but is not limited thereto.

[0177] In some embodiments, the water temperature of the soaking mode is lower than that of the heavy-stain cleaning mode. The water volume (ie, the water spraying volume) of the soaking mode is higher than that of the heavy-stain cleaning mode. Example 3

[0178] The self-cleaning method provided in this embodiment is applied to the cleaning system in any implementation of the aforementioned embodiment 1, for example: the cleaning system includes a cleaning device and a base, the cleaning device includes a body and a floor brush, a roller brush and a water divider are provided in the floor brush, and a suction device is provided in the body; a cleaning tank for accommodating the roller brush is provided on the base, and an infrared heating device is provided in the base for heating the roller brush, and the infrared heating device includes an infrared emitter and a transmission part, and both are located below the roller brush.

[0179] like Fig. 9 As shown, the self-cleaning method includes: S110, in response to the drying instruction, controlling the cleaning device to enter a drying mode; in the drying mode, the water separator is in a closed state, the roller brush rotates, and the infrared heating device is in a heating state; S120, when the drying mode ends, controlling the infrared heating device to stop heating; S130, controlling the roller brush to be in a rotating state within a preset time after the infrared heating device stops heating.

[0180] The embodiment of the present application provides an infrared heating solution, which utilizes an infrared heating device throughout the entire process of roller brush cleaning, including the self-cleaning process and the spin-drying and drying stages. That is, a heating device is used to achieve the heating requirements of each stage, while also ensuring maximum drying efficiency and saving energy.

[0181] For example, in the above-mentioned drying stage, after the infrared heating device executes the preset time, the infrared heating device is directly controlled to stop heating, but the temperature on the transparent part is still very high at this time, so the residual heat can be used for further drying. In other words, in the prior art, the heating device often needs to be turned on for 30 minutes to achieve the effect of high-temperature drying. In this solution, the infrared heating device only needs to be turned on for 25 minutes, and then the residual temperature can be used to complete the heating and drying.

[0182] And in the residual heating state, the roller brush keeps rotating, and the roller brush bristles are attached to the transmissive part, so that the residual heat can be used for ironing, thereby ensuring that the roller brush bristles are in a flat attached state after drying. At the same time, the rotation of the roller brush can also prevent the roller brush bristles from being attached at one angle all the time, which will cause the roller brush bristles to be burned.

[0183] Exemplarily, the drying instruction may also be an instruction carried in the self-cleaning instruction. After the controller responds to the self-cleaning instruction, it may automatically enter the drying stage after cleaning and drying the roller brush.

[0184] In some optional embodiments, the above step S130 includes: controlling the roller brush to rotate forward and reverse alternately.

[0185] The reverse rotation of the roller brush can turn up the bristles, and the heat can be more easily transferred to the inside of the roller brush, thereby improving the drying efficiency of the roller brush. The forward rotation of the roller brush can use the contact between the roller brush and the transmission part to iron the bristles of the roller brush, ensuring that the roller brush is smoother. Therefore, the alternating forward and reverse rotation process can improve the drying efficiency and drying effect on the basis of reducing the risk of the roller brush being burned. At the same time, the last action before the roller brush stops rotating can be controlled to be configured as forward rotation. At this time, the roller brush bristles are relatively soft, and the last action of forward rotation can ensure that the roller brush bristles are smoother.

[0186] The other steps of self-cleaning in the embodiment of the present application can be referred to as described in Example 2, for example: the aforementioned spin-drying stage can be performed before the drying stage, the aforementioned first cleaning mode can be performed in the spin-drying stage, and the soaking washing mode or the heavy dirt cleaning mode can be performed according to the state of the roller brush, etc., which will not be repeated here.

[0187] For other structures of the cleaning system of the embodiment of the present application, refer to those described in Example 1. For example, the infrared heating device includes at least one of a heat sink, a reflector, a fan and a fixed bracket, and the description will not be repeated.

[0188] In the embodiments of the present application, each embodiment or implementation method is described in a progressive manner. Under the premise of not contradicting each other, each embodiment can be combined to form a new embodiment. Example 4

[0189] The self-cleaning method provided in this embodiment is applied to the cleaning system of any of the aforementioned embodiments, for example: the cleaning system includes a cleaning device and a base, the cleaning device includes a body and a floor brush, the floor brush is provided with a roller brush and a water divider, and the body is provided with a suction device; a cleaning tank for accommodating the roller brush is provided on the base, a detection device and an infrared heating device are provided in the base, the infrared heating device is used to heat the roller brush, and the infrared heating device includes an infrared emitter and a transmission part, and both are located below the roller brush.

[0190] like Fig.10 As shown, the self-cleaning method includes: Step S210, in response to the self-cleaning instruction, controlling the cleaning device to enter the first cleaning mode, the first cleaning mode including the first cleaning stage and the second cleaning stage; in the first cleaning mode, controlling the infrared heating device to turn on, the water distributor to spray water, and the roller brush to rotate; Step S220: After the cleaning device executes the first cleaning stage, the detection device is controlled to detect dirt on the roller brush, determine the state of the roller brush, and continue to execute the second cleaning stage.

[0191] During the self-cleaning process of the embodiment of the present application, the self-cleaning instruction is directly responded to, and the self-cleaning state is directly entered according to the instruction, the control enters the first cleaning mode, and the first cleaning mode is divided into two stages. After the first cleaning stage is executed, the dirt detection action is started. Such a setting can ensure that cleaning equipment such as a floor scrubber can perform the self-cleaning action at the first time. If it is set to make a judgment after obtaining the self-cleaning instruction, then the floor scrubber must react for a period of time before it can really enter the self-cleaning mode. The reaction time is too slow, and the time from obtaining the instruction to the end of the self-cleaning execution is too long, and the user experience is too poor.

[0192] In other words, the self-cleaning method provided by the present application will execute the first cleaning mode as soon as possible regardless of the cleaning mode, and the first cleaning mode is configured as follows: the infrared heating device is turned on, the water divider sprays water, and the roller brush rotates. This ensures that the first cleaning mode can be heated by hot water. Such a setting at the initial stage of self-cleaning can help dissolve dirt as soon as possible, so as to prepare for different cleaning modes corresponding to different roller brush states later.

[0193] The degree of soiling can be detected using a soiling sensor.

[0194] For example, in floor washing, the roller brush states include but are not limited to light dirt, medium dirt and heavy dirt, and the dirtiness increases in sequence.

[0195] Infrared emitters heat the cleaning water to improve the dissolution of dirt and enhance the cleaning effect.

[0196] The self-cleaning process of the embodiment of the present application includes the following steps: washing, drying and drying, etc. It can be understood that step S210 and step S220 are both steps of the washing (also known as water washing) stage of self-cleaning.

[0197] In some optional embodiments, determining the degree of dirtiness of the roller brush includes: step S211, determining the state of the roller brush according to RGB information detected by the RGB dirtiness detector.

[0198] The RGB dirt detector refers to a device with a color system (Red Green Blue, RGB) detection function. It is understandable that the dirt detector can also be other forms of detectors, and is not limited thereto.

[0199] The RGB dirt detector can accurately capture color information, brightness information, etc., making it easier to distinguish stains from other environmental information, thereby improving the accuracy of stain recognition. It can also distinguish different degrees of dirt based on color information, brightness information, etc., thereby improving the accuracy of identifying different degrees of dirt.

[0200] In some optional embodiments, before step S210, the self-cleaning method further includes: The roller brush is subjected to a stall test, which includes controlling the roller brush to rotate forward or reverse alternately, and the reversal angle of the roller brush is less than 360°.

[0201] The stall test can promptly determine whether the roller brush is stalled, and perform overcurrent protection on the roller brush motor to ensure safety during use.

[0202] During the reversal process, the reversal angle of the roller brush is less than 360°, which can reduce the entanglement and other dirt spitting out from the front of the roller brush, and the dirt can be brought to the dirt suction port of the floor brush, and then collected under the action of negative pressure. This further improves the cleaning effect of the dirt on the roller brush.

[0203] The alternating forward and reverse rotation of the roller brush is also beneficial to further improve the cleaning effect of the entangled objects. For example, when the roller brush motor drives the cleaning element to rotate forward, the scraper on the floor brush can pick up and cut the entangled objects. By rotating the roller brush reversely, the entangled objects tightened on the roller brush can be loosened. When the entangled objects are loosened, the roller brush can be rotated forward again to allow the scraper to pick up and cut the entangled objects again. In this way, the entangled objects can be better cleaned during the stall test by alternating forward and reverse rotation.

[0204] In some optional embodiments, the reversal angle of the roller brush is 280° to 340°, and the starting point of the reversal angle is the contact point O between the roller brush and the transmission member. Figure 4 As shown), and the line connecting the contact point and the roller brush axis ( Figure 4 The vertical dotted line in the figure) is perpendicular to the horizontal plane (the horizontal dotted line in the figure).

[0205] Here, the "contact point O" refers to Figure 4 As shown, it is also roughly the tangent point between the horizontal plane and the bottom of the roller brush 110.

[0206] Exemplarily, the reversal angle of the roller brush may be 280°, 290°, 300°, 310°, 320°, 330° or 340°.

[0207] The roller brush reversal angle of 280° to 340° can better prevent dirt from being spit out from the front of the roller brush, and more dirt can be brought to the dirt suction port of the floor brush.

[0208] Specifically, most of the dirt in the prior art will appear on the roller brush cover, water divider, scraper and other positions. Reversal can be used to better clean the dirt in the above-mentioned positions. The contact position between the roller brush and the base is set to the starting point, and then the reversal angle of the roller brush is controlled to be between 280° and 340°. It can be ensured that the roller brush can be reversed to clean the above-mentioned positions. That is, controlling the reversal of 280° can ensure that the roller brush can clean at least the roller brush cover and other positions, thereby achieving the above-mentioned dirt cleaning. Setting 340° can ensure that the above-mentioned dirt will not be spit out by the roller brush, and at the same time the dirt can be moved to the above-mentioned dirt suction position, which not only ensures the cleaning effect, but also prevents the dirt from appearing in other positions.

[0209] In some optional embodiments, performing a stall test on the roller brush includes: After controlling the roller brush motor to drive the roller brush to rotate forward for a first preset time, the roller brush motor is then controlled to drive the roller brush to rotate reversely for a second preset time; In response to the roller brush being in forward rotation, the current of the roller brush motor being greater than or equal to a first current value, and / or in response to the roller brush being in reverse rotation, the current of the roller brush motor being greater than or equal to a second current value, it is determined that the roller brush is stalled; wherein the second current value is greater than the first current value.

[0210] The stall test can promptly determine whether the roller brush is stalled, and perform overcurrent protection on the roller brush motor to ensure safety during use.

[0211] In some embodiments, the forward and reverse rotations of the roller brush are repeated at least N times, and in response to the current of the roller brush motor in each forward rotation being less than the first current value and the current of the roller brush motor in each reverse rotation being less than the second current value, the stall test passes and the self-cleaning action is performed. 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.

[0212] Exemplarily, the first preset time is 0.8s-2.0s, and the second preset time is 0.6s-2.0s. For example, the first preset time is 1.0s, and the second preset time is 0.8s.

[0213] Exemplarily, the first current value is 2.0-3.0A, and the second current value is 3.0-5.0A. For example, the first current value is 2.0A, and the second current value is 4.0A. Or, the first current value is 2.5A, and the second current value is 4.5A.

[0214] For example, if a stall is detected, the controller can issue an alarm to remind the user to manually clean the blocked dirt. In this case, the controller can control the cleaning device and related parts of the base station to stop working, and continue to perform stall detection and subsequent self-cleaning actions after the user has cleaned the blockage and re-issued the self-cleaning instruction.

[0215] In some optional embodiments, the self-cleaning method further comprises: If the roller brush is slightly dirty, the cleaning device is controlled to enter a spin-drying mode after the first cleaning mode is completed; If the roller brush is in a medium or heavy dirty state, then at the end of the second cleaning stage, the cleaning device is controlled to enter a second cleaning mode; wherein, when the roller brush is in a medium dirty state, the temperature of the cleaning water in the second cleaning mode is lower than the temperature of the cleaning water in the second cleaning mode when the roller brush is in a heavy dirty state.

[0216] The above scheme introduces cleaning methods under light pollution state, medium pollution state and heavy pollution state. Specifically, when it is judged to be a light pollution state, the current roller brush can complete cleaning after two stages of hot water cleaning in the first cleaning mode and enter the spin-drying stage. That is, there is no need to waste resources or time on other cleaning, and the self-cleaning time can be further controlled and resource waste can be prevented.

[0217] If it is detected as a medium or heavy contamination state, after executing two stages of hot water cleaning in the first cleaning mode, the second cleaning mode is entered. The second cleaning mode is configured to have a larger water spray volume or a higher water temperature, or both, and the infrared heating device remains on, that is, in the medium or heavy contamination state, the two hot water cleaning stages of the first cleaning mode and the self-cleaning of the second cleaning mode are utilized, thereby further ensuring the cleaning effect of the roller brush.

[0218] In some optional embodiments, the self-cleaning method further comprises: In the second cleaning mode, the temperature of the cleaning water is controlled by providing different water volumes; wherein the water volume of the cleaning water is negatively correlated with the temperature of the cleaning water.

[0219] When other conditions are the same or approximately the same (for example, the infrared transmitter power remains unchanged, the heating time is equal or not much different), the larger the amount of water used for cleaning, the lower the water temperature; conversely, the smaller the amount of water used for cleaning, the higher the water temperature. There is a negative correlation between water volume and water temperature. By controlling the water volume, the water temperature can be controlled, which is simpler and more convenient.

[0220] In some optional embodiments, the second cleaning mode includes a soaking and washing mode, and if the roller brush is in a medium-dirty state, the cleaning device is controlled to enter the soaking and washing mode after the first cleaning mode is completed, and enters the spin-drying mode after the soaking and washing mode is completed; The immersion washing mode includes controlling the infrared heating device to turn on, the water distributor to spray water, the roller brush to rotate, and the water spray volume is between 70-90ml.

[0221] The beneficial effects of soaking washing are described above and will not be repeated here.

[0222] In some optional embodiments, the second cleaning mode includes a heavy dirt cleaning mode; If the roller brush is in a heavy-dirt state, the cleaning device is controlled to enter a heavy-dirt cleaning mode after the first cleaning mode ends; The heavy dirt cleaning mode includes controlling the infrared heating device to turn on, the water distributor to spray water, the roller brush to rotate, and the water spray volume to be between 50-70ml, and controlling the water temperature in the cleaning tank to be 90-100°.

[0223] The beneficial effects of the heavy dirt cleaning mode are described above and will not be repeated here.

[0224] In some optional embodiments, in the first cleaning stage, the water distributor stops spraying water when the water spray volume reaches 45-55 mml; In the second cleaning stage, stop spraying water when the water dispenser sprays 45-55ml of water; After the water distributor stops spraying water in the first cleaning stage, and before the water distributor sprays water in the second cleaning stage, the suction device is controlled to perform the suction action. The beneficial effects here refer to the above, and will not be described again.

[0225] Optionally, after the spin drying mode ends, the drying mode is entered. The self-cleaning method also includes: When the drying mode ends, the infrared heating device is controlled to stop heating; Within a preset time after the infrared heating device stops heating, the roller brush is controlled to be in a rotating state. The beneficial effects here refer to the above and will not be described again.

[0226] In some optional embodiments, the base further includes a temperature detector, and both the temperature detector and the infrared emitter are located in a chamber formed by the aforementioned reflective component and the transmissive component, and the temperature detector infrared emitter is used to detect the air temperature adjacent to the infrared emitter.

[0227] The temperature detector detects the lower air temperature instead of directly detecting the higher temperature of the infrared emitter or the transmission component temperature, which is beneficial to reduce the damage of the temperature detector.

[0228] In some optional embodiments, the self-cleaning method further comprises: controlling the working parameters of the infrared emitter so that the temperature detected by the temperature detector is 90°C-120°C, on this basis, the temperature of the transmission element can reach 220-260°C.

[0229] When it is lower than 90℃, the temperature of the transmissive component is difficult to heat the liquid on it to a higher temperature (such as 100℃), while too high temperature, such as higher than 120℃, will cause the temperature to rise too high, thereby forming too much steam and too little water. 90℃-120℃ can ensure that the amount of water retained on the transmissive component during the cleaning phase is appropriate, and the amount of steam formed is appropriate. That is to say, within this temperature range, it can not only dissolve dirt at high temperature, but also achieve a certain amount of water to form a soaking effect, and can also use the high temperature of steam for sterilization, which can at least effectively improve the cleaning effect of the cleaning phase.

[0230] Working parameters include but are not limited to: power, heating time, etc.

[0231] In some embodiments, the temperature detected by the temperature detector is controlled to be between 90° C. and 115° C. For example, the temperature detected by the temperature detector is controlled to be 90° C., 100° C., 110° C. or 115° C. by controlling the working parameters of the infrared emitter.

[0232] In some embodiments, the temperature of the spin drying stage is set at 90°C-115°C, preferably 110°C.

[0233] Other contents not mentioned in this embodiment are the same as those in Embodiment 2 and will not be described again.

[0234] For example, the cleaning equipment takes a floor scrubber as an example, and the self-cleaning process of the floor scrubber generally includes: S310, the floor scrubber is connected to the signal input interface of the base through the signal output interface and transmits a signal; S311, starting the carbon fiber heating tube (i.e., infrared emitter), passing the electric current through the carbon fiber, causing the molecules inside the carbon fiber to move, converting the electrical energy into thermal energy, and transmitting it to the external environment quickly and evenly in the form of far-infrared radiation, thereby achieving a heating effect; Its light radiation is concentrated in the infrared band between 1.5-15μm, which increases the absorption wavelength of organic matter and the infrared radiation intensity by more than 30%, so it has a strong infrared radiation effect.

[0235] S312, the user releases a self-cleaning and drying signal (i.e., sends a self-cleaning instruction) to the main control panel (i.e., the controller) by pressing a handle button on the floor scrubber; S313, after the base control board receives the signal, it obtains the self-cleaning instruction, turns on the infrared device, performs the stall test, controls the rear-end fan to start, and then the carbon fiber heating tube starts to work, generates infrared radiation of a specific wavelength, focuses the infrared radiation through the reflector and evenly irradiates it on the roller brush through the perspective film, and the roller brush rotates at a uniform speed during the drying process (there will be forward and reverse rotation during the rolling process); During the cleaning, spinning and drying process after the stall test, the temperature and humidity control system monitors the humidity of the roller brush, drying environment temperature and other parameters in real time, and automatically adjusts the radiation intensity of the carbon fiber heating tube to achieve more precise drying control.

[0236] S314, the stall test process includes forward rotation for 1s, and after stopping, reverse rotation for 0.8s, the reversal angle is 300-340°, the purpose of not reversing a full circle is to prevent garbage from being spit out, and to just turn the garbage to a position close to the suction port. Forward rotation and reverse rotation are performed alternately 5 times (that is, forward and reverse rotation are performed alternately five times). The reversal angle of the roller brush is 330°. If the current of the roller brush motor is found to be less than 2A during forward rotation, it indicates that it is not stalled. If the current of the roller brush motor is found to be greater than or equal to 2A during forward rotation, it indicates stalled; if the current of the roller brush motor is found to be less than 4A during reverse rotation, it indicates that it is not stalled. If the current of the roller brush motor is found to be greater than or equal to 4A during reverse rotation, it indicates stalled.

[0237] S315. After the stall test, the hot water washing stage is entered. The hot water washing is divided into two stages, namely the first cleaning stage and the second cleaning stage. After the first cleaning stage, the RGB dirt detector is used to detect dirt, and different self-cleaning modes are selected according to the degree of dirt. Specifically, if the detection is a light dirt stage, the spin-drying stage is directly entered after the second cleaning stage. The medium dirt stage is the soaking washing stage after the second cleaning stage. The heavy dirt stage is the high-temperature washing stage (100°C) after the second cleaning stage. The water volume of the hot water washing stage is 100ml, the water volume of the high-temperature washing stage is 60ml, and the water volume of the soaking washing stage is 80ml.

[0238] The temperature in the spin drying stage is set at 90°C-120°C, preferably 110°C.

[0239] S316, started during the stall test, the infrared transmitter remains on until the self-cleaning is completed.

[0240] An NTC thermometer is set inside the base, which detects the air temperature. The detection temperature range is controlled at 90℃ to 115℃. When it is lower than 90℃, the temperature of the transmission part is difficult to heat the liquid on it to 100℃, and higher than 115℃ will cause the temperature to rise too high, resulting in too much steam and too little water. The temperature range of 90℃ to 115℃ and the three self-cleaning modes mentioned above can ensure the appropriate temperature, water volume and steam volume, which can not only dissolve dirt at high temperature, but also achieve a certain immersion of water, and sterilize with the high temperature of steam.

[0241] S317. At the same time, after the spin drying is completed, the drying stage begins. The infrared transmitter continues to heat during the drying stage. The roller brush can be ironed during both the spin drying and drying stages. After the drying is completed, the infrared transmitter stops heating, but the roller brush does not stop rotating immediately. It continues to rotate alternately forward and reverse to utilize the residual heat for heating and avoid the risk of burning the roller brush. Therefore, after the spin drying is completed, the roller brush continues to rotate for a certain period of time. The fan can be turned on throughout the process.
