Description

Technical Field

[0001] This application relates to the field of cleaning technology, and particularly 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 devices such as floor washers and mopping and sweeping integrated machines have become more and more popular, reducing the burden of human housework.

[0003] Taking the floor washer as an example, after the floor washer completes the cleaning work and is placed back on the base, it performs a self-cleaning action. The cleaning process of the roller brush generally includes two steps: hot water washing the roller brush and hot air drying the roller brush. In the current floor washer base, the two steps are completed by two different sets of structures respectively. In the hot water washing stage, heating components such as PTC (Positive Temperature Coefficient) heaters are arranged below the roller brush receiving groove base on the base to heat the water for washing the roller brush. In the hot air drying stage, usually, the heated air around the resistance wire is blown to the surface of the roller brush through the air duct in the base by heating the resistance wire and cooperating with the blower. However, the above two sets of structures are complex, which not only increases the assembly difficulty 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 bristles often explode, resulting in poor cleaning effect during the next cleaning and high starting current and other problems. 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 the embodiments of the present disclosure, a self-cleaning method is proposed, which is applied to a cleaning system. 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 distributor are arranged in the floor brush, and a suction device is arranged in the body;

[0006] A cleaning groove for accommodating the roller brush is provided on the base, and an infrared heating device is arranged in the base. The infrared heating device includes an infrared emitter and a transmissive member, and both are located below the roller brush;

[0007] The self-cleaning method includes:

[0008] In response to the drying instruction, control the cleaning device to enter the drying mode;

[0009] 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 spin-dried.

[0010] After the current floor washer finishes cleaning, it often performs self-cleaning. However, the existing self-cleaning usually takes a long time. It usually uses PTC or heating wires to directly heat hot water to achieve hot water cleaning. High-end models will additionally use a set of heating wires to heat air for drying. Therefore, common floor washers use two heat sources to achieve hot water heating and drying.

[0011] Moreover, the drying method mainly uses a separate hot air drying method. During the spin-drying stage, since the roller brush is in a high-speed spinning state, if only dried by hot air at this time, the scattered water will splash everywhere. At the same time, the roller brush bristles will become very messy due to only being blown by hot air. Based on this, the spin-drying effect in the current technology is not good, and it cannot save a lot of drying time for the subsequent drying work. The reason is that when the roller brush becomes very messy, its drying effect becomes uneven, and since some of the roller brush bristles stand up, the interference fit with components such as the roller brush cover becomes larger, so the starting current will also be very large.

[0012] The solution provided by this application can not only make the structure more compact, but also make the self-cleaning efficiency and effect better, as follows.

[0013] First: The heat source used in both the water washing stage and the drying stage in this application is the same, which is the infrared heating device. Specifically, this patent can achieve multi-functional self-cleaning without multiple heaters. The benefit is that whether it is drying or self-cleaning heating, the control logic is simpler, without constantly switching different heating elements. It should be understood that starting each heating element requires a large starting current and more time for preheating, while only using one heat source can completely avoid the above problems, saving the switching time, the preheating time of multiple heat sources, and combining the fast heating characteristics of the infrared device to make the overall efficiency of the entire self-cleaning process higher.

[0014] Second: The present application enables higher cleaning efficiency through multiple structures and logical controls. Specifically, after the water washing is completed, that is, during the spin-drying stage, the infrared heating device is controlled to start. Imagine that during the spin-drying stage, the water on the base is very little (because the sewage will be suctioned away after the water washing is completed). At this time, the roller brush is in contact with the transmissive member, and the transmissive member is in a high-temperature state. Therefore, while spin-drying, the roller brush can also be ironed on the transmissive member. The shapes of the transmissive member and the roller brush are adapted to each other, both in an arc state. At this time, the roller brush can be dried faster through the ironing of the transmissive member, and at the same time, the roller brush can be ensured to be flatter.

[0015] Third: Since the drying process is intervened during the spin-drying stage, the roller brush can be dried while spin-drying. Specifically, in the subsequent drying stage, since the spin-drying stage has already started, the preheating and heating times are saved, and it can directly enter the drying state. Secondly, since heating is carried out during the spin-drying stage, some moisture will also be evaporated due to the temperature during spin-drying. Based on this, the solution of the present application enables a significant improvement in the overall efficiency of self-cleaning by intervening the heating and ironing during the spin-drying stage, and the self-cleaning effect is also better.

[0016] Fourth: In the prior art, the heating method usually adopts the hot air method. Therefore, the power of the blower is often very large. In the present application, the heating method mainly adopts the infrared heating method, which is quieter. There is no need to use a large-power blower to blow for drying separately. Based on this, using the above infrared heating method can make the noise in the overall self-cleaning process smaller, so as to achieve the functions of basically silent washing and silent drying.

[0017] Optionally, the infrared heating device includes a heat dissipation member, and the heat dissipation member is located below the infrared emitter;

[0018] The base further includes a blower. In the spin-drying mode, the blower is controlled to be turned on to blow the heat of the heat dissipation member towards the roller brush.

[0019] It should be understood that the heat dissipation member of the present application is used to absorb the extra-dissipated light or heat of the infrared emitter, so as to prevent other components of the base from being damaged by heat. Specifically, it mainly aims at the heat dissipated below the infrared emitter, and a blower is set on this basis. The power of the blower here can be selected as a blower with a relatively small power, which is used to disperse the heat of the heat dissipation member, and then disperse the concentrated heat on the heat dissipation member.

[0020] In other words, the heat dissipation member is used to centrally absorb the extra-dissipated heat of the infrared emitter, and then the blower is used to blow towards the heat dissipation member, so as to achieve the heat dissipation effect. Correspondingly, the heat dissipation member can also be made into a dark color, such as black, gray, etc.

[0021] Meanwhile, on this basis, a corresponding air duct is provided in the base, and a fan is used to blow away the heat of the heat dissipation component, and the air duct outlet faces the roller brush. In this way, the cooperation of the fan, the heat dissipation component, the infrared emitter, the air duct, etc. can realize both multiple heating of the roller brush and ensure that the base is not damaged by heat. Specifically, in this solution, the roller brush is directly heated by the infrared emitter and also heated by the hot air of the heat dissipation component. That is to say, multiple heating is realized by using a set of devices. Compared with the heating solutions in the prior art, there are more heating methods and better heating effects.

[0022] Optionally, the cleaning device further includes a detection device, and the self-cleaning method includes:

[0023] Before executing the drying mode, controlling the cleaning device to perform a self-cleaning action;

[0024] The self-cleaning action includes:

[0025] In response to a self-cleaning instruction, controlling the cleaning device to enter a first cleaning mode, and the first cleaning mode includes a first cleaning stage and a second cleaning stage;

[0026] In the first cleaning mode, controlling the infrared heating device to be turned on, the water distributor to perform water spraying, and the roller brush to rotate;

[0027] When the cleaning device executes the first cleaning stage, controlling the detection device to perform a dirt detection on the roller brush, judging the state of the roller brush, and continuing to execute the second cleaning stage;

[0028] The state of the roller brush includes a light dirt state, a medium dirt state, and a heavy dirt state.

[0029] In this application, during the self-cleaning process, directly in response to the self-cleaning instruction, and directly enter the self-cleaning state according to this instruction, control to enter the first cleaning mode, and divide the first cleaning mode into two stages. After executing the first cleaning stage, start to execute the dirt detection action. Such a setting can ensure that a cleaning device such as a floor washer can perform the self-cleaning action in the first place. If it is set to make a judgment first after obtaining the self-cleaning instruction, then the floor washer will inevitably need to react for a period of time before it can truly intervene in the self-cleaning mode. The reaction time is too slow, the time from obtaining the instruction to the end of the self-cleaning execution is too long, and the user experience is too poor.

[0030] In other words, for the self-cleaning method provided in this application, regardless of the cleaning mode, the first cleaning mode will be executed immediately. The first cleaning mode is configured such that the infrared heating device is turned on, the water distributor sprays water, and the roller brush rotates. This can ensure that the first cleaning mode can be heated with hot water. Thus, setting it like this at the initial stage of self-cleaning can help dissolve dirt immediately, in preparation for different cleaning modes corresponding to different states of the roller brush later.

[0031] Optionally, in the first cleaning stage, when the water spray volume of the water distributor reaches 45 - 55 mml, stop spraying water;

[0032] In the second cleaning stage, when the water spray volume of the water distributor reaches 45 - 55 ml, stop spraying water;

[0033] After the water distributor stops spraying water during the execution of the first cleaning stage and before the water distributor sprays water during the second cleaning stage, control the suction device to perform a suction action.

[0034] 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. Specifically, for example, the duration of the first cleaning stage is set to 6 s, and spraying water for 2 s can meet the above requirements. Then, after spraying water for 2 s, control the water distributor to stop spraying water. The purpose of controlling the above water volume is as follows.

[0035] First: Since it is the initial stage, the degree of dirt of the current floor washer is not clear. Controlling the above water volume can prevent water waste. At the same time, since the infrared emitter has just started, it takes a certain amount of time to heat up to the target temperature. Controlling the above water volume can ensure that the water temperature can quickly reach a suitable temperature, such as 60 °C, etc.

[0036] Second: Since the first cleaning mode is divided into two stages, allocating a certain amount of water volume for each stage can achieve multiple small - water - volume cleanings, and can also ensure enhanced cleaning effect while not wasting water.

[0037] Optionally, when the dirt state of the roller brush is a light - dirt state, control the cleaning device to enter the drying mode after the first cleaning mode ends;

[0038] When the dirt state of the roller brush is a medium - dirt state, control the cleaning device to enter the soaking - wash mode after the first cleaning mode ends, and enter the drying mode after the soaking - wash mode is completed;

[0039] The soaking - wash mode includes controlling the infrared heating device to turn on, the water distributor to spray water, and the roller brush to rotate, and the water spray volume is between 70 - 90 ml.

[0040] In the above solution, cleaning methods in the light pollution state and the medium pollution state are introduced. Specifically, when it is determined to be in the light pollution 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, which can further control the self-cleaning time and prevent resource waste.

[0041] If it is detected to be in the medium pollution state, after performing two-stage hot water cleaning in the first cleaning mode, it enters the soaking washing mode. In the soaking washing mode, the configured water spraying amount is larger, and the above water amount is controlled between 70-90 ml 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 pollution state, the two hot water cleaning stages of the first cleaning mode and the self-cleaning of the soaking washing mode are utilized to further ensure the cleaning effect of the roller brush.

[0042] Optionally, when the state of the roller brush is in the heavy pollution state, the cleaning device is controlled to enter the heavy pollution cleaning mode after the first cleaning mode ends;

[0043] The heavy pollution 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 amount is between 50-70 ml, and controlling the water temperature in the cleaning tank to be between 90-100 °C.

[0044] When it is determined to be in the heavy pollution state, after performing two hot water self-cleaning stages of the first cleaning mode, it enters high-temperature self-cleaning. At this time, the water spraying amount is controlled between 50-70 ml to ensure that the above water amount can be quickly heated to 90-100 °C, and high-temperature cleaning and dissolution are realized by using high temperature and larger water amount, thereby ensuring the cleaning effect of the above roller brush.

[0045] In other words, the present application provides an intelligent cleaning method. By directly entering the first cleaning mode, it is divided into two stages, and the state of the roller brush is judged when the second stage is executed, so as to determine the next cleaning action, which not only ensures the rapid realization 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.

[0046] According to the second aspect of the embodiments of the present disclosure, a self-cleaning method is proposed, which is applied to a cleaning system. 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 distributor are arranged in the floor brush, and a suction device is arranged in the body;

[0047] The base is provided with a cleaning tank for accommodating the roller brush, and an infrared heating device is arranged inside the base. The infrared heating device includes an infrared emitter and a transmissive member, and both are located below the roller brush. The self-cleaning method includes:

[0048] In response to a drying instruction, control 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;

[0049] When the drying mode ends, control the infrared heating device to stop heating;

[0050] Within a preset time after the infrared heating device stops heating, control the roller brush to be in a rotating state.

[0051] This application provides an infrared heating solution, which uses the infrared heating device to penetrate all processes of roller brush cleaning, including the self-cleaning process and the spin-drying and drying stages. That is, a single heating device is used to meet the heating requirements of each stage, while also ensuring maximum efficiency drying and saving energy.

[0052] For example, in the above drying stage, after the infrared heating device executes for a preset time, directly control the infrared heating device to stop heating. However, the temperature on the transmissive member is still very high at this time, so the remaining 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, only need to turn on the infrared heating device for 25 minutes, and then use the remaining heat to complete the heating and drying.

[0053] And in the state of remaining heat heating, the roller brush keeps rotating, and the roller brush bristles are attached to the transmissive member, which can realize ironing with the remaining heat, so as to ensure 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 an angle all the time, thus causing the problem of the roller brush bristles being damaged by heat.

[0054] Optionally, controlling the roller brush to be in a rotating state includes: controlling the roller brush to rotate forward and backward alternately.

[0055] During the reverse rotation of the roller brush, the bristles can be turned up, and the heat can be more easily transferred to the inside of the roller brush, improving the drying efficiency of the roller brush. And the forward rotation of the roller brush can use the contact between the roller brush and the transmissive member to iron the bristles of the roller brush to ensure that the roller brush is flatter. Therefore, the alternating rotation process of forward and backward rotation can improve the drying efficiency and drying effect on the basis of reducing the risk of the roller brush being damaged by heat. At the same time, the last action before the roller brush stops rotating can be configured as forward rotation. At this time, the roller brush bristles are relatively soft, and using the last action of forward rotation can ensure that the roller brush bristles are more flat.

[0056] Optionally, the infrared heating device further includes a heat dissipation member and a reflection member; in the vertical direction, the reflection member and the transmission member are respectively located on opposite sides of the infrared emitter, and the heat dissipation member is located below the reflection member.

[0057] The function of the heat dissipation member is as described above and will not be repeated.

[0058] Optionally, the base further includes a blower, ventilation holes located on the periphery of the roller brush, and an air duct located between the outlet of the blower and the ventilation holes. At least the infrared emitter and the heat dissipation member are located in the air duct;

[0059] In the drying mode, control the blower to turn on. The air flow blown by the blower can flow through the air duct to the ventilation holes, so as to blow the heat of the infrared emitter and the heat dissipation member towards the roller brush.

[0060] The ventilation holes are the outlets of the air duct in the base described above. The ventilation holes face the roller brush. The air blown by the blower flows through the air duct to the ventilation holes and then is blown towards the roller brush by the ventilation holes. In this way, the cooperation of the blower, heat dissipation member, infrared emitter, air duct, etc. is used to realize multiple heating of the roller brush, and it can also ensure that the base is not damaged by heat.

[0061] Optionally, the reflection member and the transmission member jointly enclose a chamber, and the infrared emitter is located in the chamber; the bottom of the reflection member has an opening communicating with the chamber, and the heat dissipation member is opposite to the opening.

[0062] The chamber can better concentrate the heat generated by the infrared emitter at the roller brush. For example, one surface of the reflection member forming the chamber is a downwardly concave curved surface, and the curved surface can make the reflected infrared rays be gathered and concentrated on the roller brush. This reduces the loss of infrared rays outside the chamber and improves the utilization rate of the infrared rays emitted by the infrared emitter.

[0063] The opening can reduce the barrier between the infrared emitter and the heat dissipation member, so that the heat in the chamber can be transferred to the heat dissipation member more quickly, improving the heat dissipation effect.

[0064] Optionally, the heat dissipation member includes a heat dissipation base and at least one heat dissipation fin. The heat dissipation fin is located on the heat dissipation base and faces the opening; when there are multiple heat dissipation fins, the multiple heat dissipation fins are evenly distributed at intervals 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.

[0065] The heat dissipation base can not only increase the heat dissipation area but also serve as an installation carrier for the heat dissipation fins. The more the number of heat dissipation fins, the larger the heat dissipation surface, and the more conducive it is to improving the heat dissipation effect.

[0066] A plurality of heat sinks are evenly distributed at intervals along the length direction of the infrared emitter, so that the heat at each part of the infrared emitter 220 can be dissipated through the heat dissipation component, further improving the heat dissipation effect.

[0067] Optionally, the infrared heating device further includes a fixing bracket, and the fixing bracket is respectively connected to the base, the infrared emitter and the base, so that the infrared emitter and the heat dissipation component are both connected to the base through the fixing bracket.

[0068] The fixing bracket can limit and fix the infrared emitter, effectively improving the reliability and firmness of the connection between the infrared emitter and the base, and can also effectively reduce or avoid the shaking of the infrared emitter, thereby causing damage to the infrared emitter, which helps to improve the protection of the infrared emitter and extend the service life of the infrared emitter.

[0069] Moreover, the fixing bracket is used to install the infrared emitter and the heat dissipation component at the same time, improving the utilization rate of the fixing bracket and being beneficial to saving the internal space of the base.

[0070] Optionally, the surface of the reflecting member facing the infrared emitter is a curved surface that is concave downward, and the curved surface and the transmitting member jointly enclose the chamber.

[0071] Optionally, the infrared heating device further includes a shock pad, and the shock pad is located at the connection between the transmitting member and the reflecting member.

[0072] The shock pad can absorb the vibration generated during the self-cleaning process, reducing or even avoiding the vibration damage to the infrared heating device caused by the rotation of the roller brush, taking the cleaning device on and off the base, etc.

[0073] According to the third aspect of the embodiments of the present disclosure, a self-cleaning method is proposed.

[0074] Applied to a cleaning system, 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 distributor are arranged in the floor brush, and a suction device is arranged in the body;

[0075] A cleaning groove for accommodating the roller brush is provided on the base, a detection device and an infrared heating device are arranged in the base, and the infrared heating device includes an infrared emitter and a transmitting member, and both are located below the roller brush; the self-cleaning method includes:

[0076] In response to a self-cleaning instruction, controlling the cleaning device to enter a first cleaning mode, the first cleaning mode includes a first cleaning stage and a second cleaning stage; in the first cleaning mode, controlling the infrared heating device to be turned on, the water distributor to perform water spraying, and the roller brush to rotate;

[0077] After the cleaning device executes the first cleaning stage, control the detection device to detect the dirt on the roller brush, determine the state of the roller brush, and continue to execute the second cleaning stage;

[0078] The states of the roller brush include a light dirt state, a medium dirt state, and a heavy dirt state.

[0079] In the self-cleaning process of this application, directly in response to the self-cleaning instruction, enter the self-cleaning state according to this instruction, control to enter the first cleaning mode, and divide the first cleaning mode into two stages. After executing the first cleaning stage, start to execute the dirt detection action. Such a setting can ensure that a cleaning device such as a floor washer can perform the self-cleaning action in the first place. If it is set to make a judgment first after obtaining the self-cleaning instruction, then the floor washer will inevitably need to react for a period of time before it can truly intervene in the self-cleaning mode. The reaction time is too slow, the time from obtaining the instruction to the end of the self-cleaning execution is too long, and the user experience is too poor.

[0080] In other words, the self-cleaning method provided in this application will execute the first cleaning mode immediately regardless of the cleaning mode. And the first cleaning mode is configured such that the infrared heating device is turned on, the water distributor sprays water, and the roller brush rotates. In this way, it can be ensured that the first cleaning mode can be heated with hot water. So, at the initial stage of self-cleaning, such a setting can help dissolve dirt immediately to prepare for different cleaning modes corresponding to different states of the roller brush.

[0081] Optionally, before entering the first cleaning mode, the self-cleaning method further includes:

[0082] Perform a stall test on the roller brush. The stall test includes controlling the roller brush to rotate forward and backward alternately, and the reverse rotation angle of the roller brush is less than 360°.

[0083] The stall test can timely determine whether there is a stall situation of the roller brush, perform overcurrent protection on the roller brush motor, and ensure the safety during use.

[0084] During the reverse rotation process, the reverse rotation angle of the roller brush being less than 360° can reduce the ejection of dirt such as entanglements from the front of the roller brush, and more dirt can be brought to the dirt suction port of the floor brush and then collected under the action of negative pressure. In this way, the cleaning effect of the dirt on the roller brush is further improved.

[0085] The alternating forward and reverse rotations of the roller brush are also beneficial for further improving the cleaning effect on entanglements. For example, when the roller brush motor drives the cleaning member to rotate forward, the scraping strip on the floor brush can pick up and cut the entanglements. By reversing the roller brush, the entanglements tightened on the roller brush can be loosened. After the entanglements are loosened, the roller brush can be rotated forward again so that the scraping strip can pick up and cut the entanglements again. In this way, the forward and reverse reciprocating rotations can better clean the entanglements during the stall test.

[0086] Optionally, the reverse rotation angle of the roller brush is 280° to 340°. The starting point of the reverse rotation angle is the contact position between the roller brush and the transmission member, and the vertical connection line between the contact position and the axis of the roller brush is perpendicular to the horizontal plane.

[0087] The reverse rotation angle of the roller brush from 280° to 340° can better prevent dirt from being spit out from the front of the roller brush, and the dirt can be more brought to the dirt suction port of the floor brush.

[0088] Specifically, most of the dirt in the prior art appears in positions such as the roller brush cover, the water diverter, and the scraping strip. The reverse rotation can better clean the dirt in the above-mentioned parts. Setting the contact position between the roller brush and the base as the starting point, and then controlling the reverse rotation angle of the roller brush to be between 280° and 340°, can ensure that the reverse rotation of the roller brush can definitely clean the above-mentioned positions. That is, controlling the reverse rotation by 280° can ensure that the roller brush can clean at least positions including the roller brush cover, etc., so as to achieve the above-mentioned dirt cleaning. And setting 340° can ensure that the above-mentioned dirt will definitely not be driven 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.

[0089] Optionally, the stall test on the roller brush includes:

[0090] After controlling the roller brush motor to drive the roller brush to rotate forward for a first preset time, then controlling the roller brush motor to drive the roller brush to rotate in reverse for a second preset time;

[0091] In response to the current of the roller brush motor being greater than or equal to a first current value during the forward rotation of the roller brush, and / or in response to the current of the roller brush motor being greater than or equal to a second current value during the reverse rotation of the roller brush, it is determined that the roller brush is stalled; wherein, the second current value is greater than the first current value.

[0092] The stall test can timely determine whether the roller brush is stalled, perform overcurrent protection on the roller brush motor, and ensure the safety during use.

[0093] Optionally, the self-cleaning method further includes:

[0094] If the dirt state of the roller brush is a light dirt state, after the first cleaning mode of the cleaning device ends, control enters the drying mode;

[0095] If the state of the roller brush is medium dirt or heavy dirt, when the second cleaning stage ends, control the cleaning device to enter the second cleaning mode; wherein, when the state of the roller brush is medium dirt, the temperature of the cleaning water used in the second cleaning mode is lower than when the state of the roller brush is heavy dirt, the temperature of the cleaning water used in the second cleaning mode.

[0096] In the above solution, cleaning methods in the light dirt state, medium dirt state and heavy dirt state are introduced. Specifically, when it is judged to be in the light dirt state, the current roller brush can complete cleaning through the two-stage hot water cleaning of the first cleaning mode and enter the drying stage. That is, there is no need to waste resources or time for other cleaning, and the self-cleaning time can be further controlled and resource waste can be prevented.

[0097] If it is detected as the medium dirt state or the heavy dirt state, after performing the two-stage hot water cleaning of the first cleaning mode, start to enter the second cleaning mode. In the second cleaning mode, it 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 dirt state or the heavy dirt state, the two hot water cleaning stages of the first cleaning mode and the self-cleaning of the second cleaning mode are used to further ensure the cleaning effect of the roller brush.

[0098] Optionally, the method further includes:

[0099] In the second cleaning mode, by providing different water volumes, control the temperature of the cleaning water; wherein, the water volume of the cleaning water has a negative correlation with the temperature of the cleaning water.

[0100] Under the condition that other conditions are the same or approximately the same (such as the power of the infrared emitter remains unchanged, the heating time is equal or not much different), the larger the water volume of the cleaning water, the lower the water temperature; conversely, the smaller the water volume of the cleaning water, the higher the water temperature. The water volume and the water temperature have a negative correlation. By controlling the water volume, the control of the water temperature can be realized, which is more simple and convenient.

[0101] Optionally, the second cleaning mode includes an immersion washing mode. If the dirt state of the roller brush is the medium dirt state, after the first cleaning mode ends, control the cleaning device to enter the immersion washing mode, and enter the drying mode after the immersion washing mode is completed;

[0102] The immersion washing mode includes controlling the infrared heating device to turn on, the water distributor to spray water, and the roller brush to rotate, and the water spray volume is between 70-90 ml.

[0103] The beneficial effects of the soaking wash are as described above and will not be repeated here.

[0104] Optionally, the second cleaning mode includes a heavy stain cleaning mode;

[0105] If the state of the roller brush is a heavy stain state, control the cleaning device to enter the heavy stain cleaning mode after the end of the first cleaning mode;

[0106] The heavy stain 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 - 70 ml, and controlling the water temperature in the cleaning tank to be between 90 - 100 °C.

[0107] The beneficial effects of the heavy stain cleaning mode are as described above and will not be repeated here.

[0108] Optionally, in the first cleaning stage, stop spraying water when the water spray volume of the water distributor reaches 45 - 55 mml;

[0109] In the second cleaning stage, stop spraying water when the water spray volume of the water distributor reaches 45 - 55 ml;

[0110] After the water distributor stops spraying water in the first cleaning stage and before the water distributor sprays water in the second cleaning stage, control the suction device to perform a suction action. The beneficial effects here are as described above and will not be repeated. Optionally, the self - cleaning method further includes:

[0111] When the drying mode ends, control the infrared heating device to stop heating;

[0112] Within a preset time after the infrared heating device stops heating, control the roller brush to be in a rotating state. The beneficial effects here are as described above and will not be repeated.

[0113] Optionally, the base further includes a temperature detector. The reflector and the transmissive member jointly enclose a chamber, and both the infrared emitter and the temperature detector are located in the chamber; the temperature detector is used to detect the air temperature adjacent to the infrared emitter.

[0114] The temperature detector detects the air temperature with a lower temperature, rather than directly detecting the temperature of the infrared emitter or the transmissive member with a higher temperature, which is beneficial to reducing damage to the temperature detector.

[0115] Optionally, the self - cleaning method further includes:

[0116] Control the operating parameters of the infrared emitter so that the temperature detected by the temperature detector is 90 °C - 120 °C.

[0117] When the temperature is below 90°C, it is difficult for the temperature of the transmissive member to heat the liquid thereon to a relatively high temperature (such as 100°C). However, if the temperature is too high, such as above 120°C, it will cause the temperature to rise too high, resulting in too much steam and too little water volume. While a temperature range of 90°C - 120°C can ensure an appropriate amount of water remaining on the transmissive member during the cleaning stage and an appropriate amount of steam formed. That is to say, within this temperature range, it can not only dissolve dirt at a high temperature, but also achieve a soaking effect with a certain amount of water, and there is also high-temperature steam for sterilization, which can at least effectively improve the cleaning effect during the cleaning stage.

[0118] According to a fourth aspect of the embodiments of the present disclosure, a cleaning system is provided, characterized in that the cleaning system includes a cleaning device, a base, and a controller;

[0119] The controller is configured to execute the self-cleaning method according to any one of the embodiments of the foregoing first aspect, second aspect, or third aspect.

Among them, the drawings are not necessarily drawn to scale, and local features can 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 and scientific fields to which this application belongs.

Without contradiction, each step in an embodiment can be implemented as an independent embodiment, and the steps can be combined arbitrarily.

In addition, the optional implementation manners in an embodiment can be arbitrarily combined; furthermore, the embodiments can be arbitrarily combined. For example, some or all of the steps of different embodiments can be arbitrarily combined, and an embodiment can be arbitrarily combined with the optional implementation manners of other embodiments.

[0137] In each embodiment of the present disclosure, if there is no special description and logical conflict, the terms and / or descriptions between the embodiments are consistent and can be cited from each other, and the technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationships.

[0138] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not intended as a limitation of the present disclosure. Example 1

[0139] This embodiment provides a cleaning system. Refer to the following Figures 1 to 7 for a detailed introduction to the cleaning system.

[0140] As Figures 1 to 3 shown, the cleaning system 10 includes a cleaning device 100 and a base 200. The cleaning device 100 may include a floor brush. During operation, the cleaning device 100 travels on the surface to be cleaned, and the floor brush contacts and rubs against the surface to be cleaned to clean the surface.

[0141] Referring to Figure 1 , the floor brush 100 may include a housing, a rotary brush 110, and a traveling wheel 102. The housing is the main support structure of the floor brush 100, and the rotary brush 110 and the traveling wheel 102 may both be installed on the housing 103. For example, the housing 103 may have a receiving cavity, the rotary brush 110 may be located in the receiving cavity of the housing 103, and the rotary brush 110 may rotate about its own axis.

[0142] When the cleaning device performs cleaning work, the rotary brush 110 contacts the surface to be cleaned, and the rotary brush 110 is driven by a rotary brush motor installed inside the rotary brush 110 to rotate at a high speed, so that the rotary brush 110 can make frictional contact with the surface to be cleaned to clean the surface. The traveling wheel 102 contacts the surface to be cleaned and rolls along the surface to be cleaned to assist the cleaning device in walking on the surface to be cleaned, which can improve the stability of the floor brush 100 in walking on the surface to be cleaned.

[0143] As Figure 2 and Figure 3 shown, the base 200 is provided with a cleaning tank 211 for accommodating the rotary brush 110 of the cleaning device 100. When the cleaning device 100 docks on the base 200, the cleaning device 100 can perform self-cleaning. During the self-cleaning process, the rotary brush 110 is cleaned and dried in the cleaning tank 211.

[0144] The cleaning system further includes an infrared heating device, and the infrared heating device is located inside the base 200. As Figures 4 to 6 shown, the infrared heating device includes a transmissive member 230 and an infrared emitter 220. Both the transmissive member 230 and the infrared emitter 220 are located below the rotary brush 110, and the transmissive member 230 can contact the rotary brush 110.

[0145] The transmissive member 230 can transmit infrared rays. The infrared emitter 220 can be used to emit infrared rays, and at least part of the heat of the infrared rays emitted by the infrared emitter 220 can be radiated to the rotary brush 110 through the transmissive member 230.

[0146] After the infrared emitter 220 is turned on, a relatively high temperature can be formed on the transmissive member 230. The transmissive member 230 can iron the roller brush 110 by contacting with the roller brush 110, which not only further improves the drying efficiency but also makes the bristles smoother.

[0147] In one embodiment, the transmissive member 230 can be a glass panel, and the temperature on its back can reach 200 - 280 °C. Thus, the temperature it can achieve is higher than that of hot air or ordinary heating methods in the prior art, and it can use high temperature in cooperation with the roller brush to achieve ironing and drying.

[0148] The infrared rays generated by the infrared emitter 220 can quickly pass through the transmissive member 230 and penetrate the surface of the material of the roller brush 110, directly transferring the energy to the inside and surface of the roller brush 110, which can effectively accelerate the drying speed of the roller brush 110 and improve the drying efficiency of the roller brush 110.

[0149] Moreover, the infrared rays can provide a uniform heat distribution, which can effectively reduce or avoid the situation of local overheating or incomplete drying of the roller brush 110, and can effectively improve the drying quality.

[0150] In addition, compared with traditional hot air drying, the infrared emitter 220 provided in the embodiment of the present application can directly transfer heat to the surface and inside of the roller brush 110, with lower heat conduction loss and better energy-saving effect.

[0151] In some alternative embodiments, the transmissive member 230 can form at least part of the bottom of the cleaning tank 211.

[0152] For example, the transmissive member 230 can be connected to the base 200. In the vertical direction (a direction substantially perpendicular to the horizontal plane), the transmissive member 230 can be located between the infrared heater and the roller brush 110, and the roller brush can maintain contact with the transmissive member 230 during the rolling process.

[0153] In some alternative embodiments, as Figure 5 shown, the base 200 can have a receiving space 213, and at least part of the infrared heating device is located in the receiving space 213. For example, the infrared emitter 220, the blower 250, etc. can all be located in the receiving space 213, so that the base 200 can install and fix the above structural members. The receiving space 213 can be specifically defined and formed by the base shell 210.

[0154] In some alternative embodiments, the infrared emitter 220 can be a carbon fiber heating tube. After the infrared emitter 220 is turned on, current can be supplied 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. This heat energy can be quickly and uniformly radiated to the surroundings of the roller brush 110 in the form of infrared radiation to dry the roller brush 110.

[0155] In some alternative embodiments, the wavelength band of the infrared rays can be between 1.5 μm and 15 μm. The light in this wavelength band can be effectively absorbed by organic substances, the infrared radiation intensity can be increased by more than 30%, and it has a strong infrared radiation effect.

[0156] The transmissive member 230 can isolate the infrared emitter 220 from the roller brush 110, reduce or avoid direct contact between the roller brush 110 and the infrared emitter 220, prevent water stains, dirt, etc. on the roller brush 110 from contaminating the infrared emitter 220, and reduce the risk of damage to the infrared emitter 220 due to water stain or dirt contamination, which is beneficial to improving the protection of the infrared emitter 220.

[0157] Exemplarily, the transmissive member 230 can be a glass plate or a transparent plastic plate.

[0158] Exemplarily, the transmissive member 230 can be in the shape of a convex lens. The transmissive member 230 in the shape of a convex lens can converge the passing light so that the infrared rays passing through the transmissive member 230 can be converged and thus concentrated on the roller brush 110. This can effectively increase the amount of infrared rays projected on the roller brush 110, reduce the waste of infrared rays, thereby effectively improving the utilization rate of infrared rays and enhancing the drying efficiency of the infrared heating device for the roller brush 110.

[0159] In some alternative embodiments, as Figures 4 to 6 shown, the infrared heating device can further include a reflector 240. Along the vertical direction, the reflector 240 and the transmissive member 230 are respectively located on opposite sides of the infrared emitter 220, and the heat dissipation member 290 is located below the reflector 240. At least part of the infrared rays can be reflected by the reflector 240 to the transmissive member 230 and radiated to the roller brush 110 through the transmissive member 230. For example, the surface of the reflector 240 facing the infrared emitter 220 can be a mirror surface so that the infrared rays projected on the mirror surface of the reflector 240 can be reflected.

[0160] For example, the infrared rays generated on the surface of the infrared emitter 220 facing the roller brush 110 can be projected on the transmissive member 230 and then projected on the roller brush 110 through the transmissive member 230. The infrared rays generated on the surface of the infrared emitter 220 facing away from the roller brush 110 can be projected on the reflector 240 and then reflected on the transmissive member 230 by the reflector 240, and thus projected on the roller brush 110 through the transmissive member 230 to dry the roller brush 110.

[0161] Through the reflection of infrared rays by the reflector 240, the infrared rays generated on 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. Thereby effectively improving the utilization rate of infrared rays and enhancing the cleaning and drying efficiency of the base 200 for the roller brush 110.

[0162] In some alternative embodiments, the infrared heating device further includes a heat dissipation member 290, and the heat dissipation member 290 is located below the infrared emitter 220. The heat dissipation member 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 potential risks caused by over-concentration of heat.

[0163] Exemplarily, the length of the heat dissipation member 290 can also be approximately equal to the length of the infrared emitter 220 to improve the heat dissipation effect at different positions of the infrared emitter 220. To further improve the heat dissipation effect, optionally, the heat dissipation member 290 includes a plurality of Figure 7 heat dissipation fins 291 as shown. The plurality of heat dissipation fins 291 are evenly distributed at intervals along the length direction of the infrared emitter 220.

[0164] In some alternative embodiments, the reflector 240 and the transmissive member 230 jointly enclose a chamber 241, and the infrared emitter 220 is located inside the chamber 241; the bottom of the reflector 240 has an opening 242 communicating with the chamber 241, and the heat dissipation member 290 is opposite to the opening 242.

[0165] The chamber can better concentrate the heat generated by the infrared emitter at the roller brush. For example, the surface of the reflector forming one side of the chamber is a downwardly concave curved surface (specifically mentioned below), and the curved surface can make the reflected infrared rays be gathered and concentratedly projected onto the roller brush 110. Reducing the loss of infrared rays outside the chamber and improving the utilization rate of the infrared rays emitted by the infrared emitter.

[0166] Through the opening 242, the barrier between the infrared emitter 220 and the heat dissipation member 290 can be reduced, enabling the heat in the chamber 241 to be transferred to the heat dissipation member 290 more quickly and improving the heat dissipation effect.

[0167] In some alternative embodiments, the heat dissipation member 290 includes a heat dissipation base 292 and a plurality of heat dissipation fins 291. The heat dissipation fins 291 are located on the heat dissipation base 292 and face the opening 242. The heat generated by the infrared emitter 220 can be transferred to the heat dissipation fins 291 through the opening 242, or can also be transferred to the heat dissipation base 292, improving the heat dissipation effect.

[0168] 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.

[0169] 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.

[0170] 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.

[0171] 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.

[0172] 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.

[0173] 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.

[0174] 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 .

[0175] 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 .

[0176] 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.

[0177] For example, the longitudinal cross-sectional shape of the reflector 240 can be roughly designed as an ellipse (as Figure 6 shown). The infrared emitter 220 is located at one focus F1 of the elliptical reflector 240 and can be used to heat the water for cleaning the cleaning roller brush when self-cleaning the cleaning roller brush, so as to achieve high-temperature hot water cleaning of the roller brush; the transmissive member 230 located above the radiation source will also absorb a part of the radiation while transmitting infrared light. This part of the radiation energy can heat the light-transmitting parts. During the drying process of the roller brush 110, the relatively high-temperature light-transmitting parts can heat the roller brush, and the fact of high-temperature ironing of the roller brush can improve the drying efficiency of the roller brush and effectively save waste.

[0178] Exemplarily, as Figure 7 shown, the bottom of the reflector 240 has an opening 242, and the heat dissipation member 290 is located below the opening 242 to absorb the heat generated by the infrared emitter 220 above through the opening 242.

[0179] The reflector 240 and the transmissive member 230 can be directly connected. Alternatively, as Figure 6 shown, the infrared heating device further includes a shock pad 260, and the shock pad 260 is located at the connection between the transmissive member 230 and the reflector 240. The transmissive member 230 is connected to the reflector 240 through the shock pad 260, and the shock pad 260 can absorb vibration energy and effectively avoid damage to the transmissive member 230 and the infrared emitter 220 caused by vibration.

[0180] Referring to Figure 4 and Figure 5 shown, the base 200 can include a blower 250 located in the accommodation space 213. The blower 250 has a blowing port, and the air flow blown out through the blowing port can pass through the infrared emitter 220 and the heat dissipation member 290. If the infrared emitter 220 is in the on state, the blower 250 can transport the infrared heat emitted by the infrared emitter 220 and the heat conducted by the heat dissipation member 290 to the roller brush 110. If the infrared emitter 220 is in the off state, the blower 250 can also transport the remaining heat of the infrared emitter 220 and the heat dissipation member 290 to the roller brush 110.

[0181] As Figure 3 shown, the base 200 further includes ventilation holes 271 located on the periphery of the roller brush 110, and a duct 270 located between the outlet of the blower 250 and the ventilation holes 271 (as Figure 4As shown, 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 airflow of the air blown out from the air outlet of the blower 250 can drive the air flow around the infrared emitter 220 and the heat sink 290. It 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 on the roller brush 110. Moreover, the air blown out from the air outlet can also reduce the temperature near the infrared emitter 220 and the heat sink 290, improving the heat dissipation effect.

[0182] See Figure 6 As shown, in some alternative embodiments, the infrared heating device further includes a temperature detector 202. The temperature detector 202 can detect the air temperature near the infrared emitter 220, and the operating parameters of the infrared emitter 220 can be adjusted in a timely manner according to the temperature detected by the temperature detector 202 to keep the water volume and steam volume in the cleaning tank 211 appropriate, ensuring the cleaning effect on the roller brush 110. The temperature detector 202 detects the air temperature with a lower temperature, rather than directly detecting the temperature of the infrared emitter or the transmissive member 230 with a higher temperature, which is beneficial to reducing the damage of the temperature detector 202.

[0183] Exemplarily, the temperature detector 202 is an NTC (Negative Temperature Coefficient Sensor). However, it is not limited thereto.

[0184] Refer to Figure 6 , at least a part of the temperature detector 202 is located in the chamber 241, and the infrared emitter 220 is also located in the chamber 241. In this way, the temperature detector 202 can measure the space temperature near the infrared emitter 220.

[0185] Exemplarily, the temperature detector 202 can also be fixed on the fixing bracket 280, or the temperature detector is fixed in the base through other brackets.

[0186] The number of infrared emitters 220 can be one, two, three or more.

[0187] Refer to Figure 1 As shown, the cleaning device may further include a clean water tank 101. The clean water tank 101 can supply a cleaning liquid (including but not limited to the 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 can soak the stains on the surface to be cleaned during the cleaning process, reducing the adhesion of the stains, thereby facilitating the cleaning of the stains from the surface to be cleaned.

[0188] Along the traveling direction of the floor brush 100, the rotary brush 110 can be installed at the front end of the housing, and the traveling wheels 102 can be installed at the rear end of the housing. This can facilitate the control of the traveling direction of the floor brush 100 and is conducive to maintaining the balance of the floor brush 100 during traveling. Moreover, the rotary brush 110 preferably contacts the surface to be cleaned first, and there is no obstruction in front of the rotary brush 110, which is conducive to the rotary brush 110 cleaning the surface to be cleaned.

[0189] 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 can hold the body and swing the body to rotate the floor brush 100 relative to the body, enabling the floor brush 100 to travel to different areas (such as under a table, under a cabinet, etc.) so that the floor brush 100 can clean different areas.

[0190] Components such as a clean water tank 101 and a sewage tank can be installed on the body. The clean water tank 101 is used to hold the 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 to cooperate with the floor brush 100 to clean the surface to be cleaned. The sewage (along with foreign matters such as particles and hair) on the surface to be cleaned is sucked into the sewage tank, thus completing the cleaning process.

[0191] After the cleaning device is placed back on the base, auxiliary operations such as self-cleaning and charging of the cleaning device are realized.

[0192] The execution entity of the embodiment of the present application may be a controller provided in the cleaning device, or a controller provided in the base. Alternatively, the execution entity may also be a server corresponding to the cleaning device and the base. The server is located in the cloud and is connected to the cleaning device through a network to issue control instructions to the cleaning device and the base, or forward 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.

[0193] The above-mentioned controller may include a microcontroller unit (MCU). Of course, the above-mentioned controller may also include other devices capable of having a control function.

[0194] Exemplarily, as Figure 5 shown, the base 200 has a signal input / 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 / 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 emitter based on the self-cleaning instruction and controls the corresponding components on the cleaning device and the base to perform the self-cleaning action.

[0195] Next, it will be combined with the attachedFigures 7 to 10 , taking the controller in the cleaning device as the execution subject as an example, the self-cleaning method of the embodiment of the present application will be described. Embodiment 2

[0196] The self-cleaning method provided in this embodiment is applied to the cleaning system in any implementation manner of the foregoing Embodiment 1. The method includes:

[0197] As Figure 8 shown, in step S10, in response to the drying instruction, control the cleaning device to enter the drying mode; in the drying mode, the water separator is in the closed state, and the roller brush rotates; and in the drying mode, the infrared heating device is in the heating state, and the roller brush contacts the transmissive member, so that the roller brush can be ironed by the transmissive member while being dried.

[0198] The self-cleaning process of the embodiment of the present application includes stages such as cleaning, drying, and drying.

[0199] The drying instruction can be an instruction carried in the self-cleaning instruction. At this time, after the water washing is completed, the drying stage can be entered. In addition, the drying instruction can also be a separate instruction independent of the self-cleaning instruction.

[0200] At present, after the floor washer finishes cleaning, it often performs self-cleaning. However, the existing self-cleaning often takes a long time. It usually uses PTC or heating wires, etc. to directly heat hot water to achieve hot water cleaning. High-end machines will additionally use a set of heating wires to heat the air for drying. Therefore, common floor washers will use two heat sources to achieve hot water heating and drying.

[0201] And the drying method mainly uses the hot air drying method. Therefore, after the drying is completed, the roller brush bristles are in a messy state. In such a state, when the roller brush realizes the next cleaning, it will cause uneven moisture of the roller brush, and because some of the roller brush bristles stand up, the interference fit with components such as the roller brush cover becomes larger, so the starting current will also be very large.

[0202] The solution provided in the embodiment of the present application can not only make the structure more compact, but also make the self-cleaning efficiency and effect better, as follows.

[0203] First: In the embodiments of the present application, the heat source used in both the water washing stage and the drying stage is one and the same, namely an infrared heating device. Specifically, this patent can achieve multi-functional self-cleaning without the need for multiple heaters. The advantage is that whether it is drying or self-cleaning heating, the control logic is simpler, without the need to continuously switch different heating elements. It should be understood that starting each heating element requires a large starting current and also takes a relatively long time for preheating. By using only one heat source, the above problems can be completely avoided. It saves the switching time, the preheating time of multiple heat sources, and combined with the fast heating characteristic of the infrared device, the overall efficiency of the entire self-cleaning process is higher.

[0204] Second: In the embodiments of the present application, through multiple structures and logical controls, the cleaning efficiency is higher. Specifically, after the water washing is completed, that is, during the spin-drying stage, the infrared heating device is controlled to start. Imagine that at the spin-drying stage, the amount of water on the base is very small (because the sewage will be suctioned away after the water washing is completed). At this time, the roller brush is in contact with the transmissive member, and the transmissive member is in a high-temperature state. Therefore, during spin-drying, the roller brush can also be ironed on the transmissive member. The shapes of the transmissive member and the roller brush are adapted to each other, both being in an arc state. At this time, the roller brush can not only be dried faster through the ironing of the transmissive member, but also ensure that the roller brush is flatter.

[0205] Third: Since the drying process is intervened during the spin-drying stage, the roller brush can be dried while spin-drying. Specifically, in the subsequent drying stage, since it has already been started during the spin-drying stage, the preheating and heating times are saved, and it can directly enter the drying state. Secondly, since heating is carried out during the spin-drying stage, part of the water will also be evaporated due to the temperature during spin-drying. Based on this, the solution of the present application by intervening the heating and ironing during the spin-drying stage has significantly improved the overall efficiency of self-cleaning, and the self-cleaning effect is also better.

[0206] Fourth: In the prior art, the heating method mainly uses hot air, so the power of the fan is often very large. In the present application, the heating method mainly uses infrared heating, which is quieter. There is no need to use a large-power fan alone to blow for drying. Based on this, using the above infrared heating method can make the noise during the overall self-cleaning process smaller, thus realizing the functions of basically silent washing and silent drying.

[0207] In some alternative embodiments, the infrared heating device includes the aforementioned heat dissipation member, and the heat dissipation member is located below the infrared emitter; the base further includes the aforementioned fan; the self-cleaning method includes: in the spin-drying mode, controlling the fan to turn on to blow the heat of the heat dissipation member towards the roller brush.

[0208] It should be understood that the heat dissipation component in the embodiments of the present application is used to absorb the light or heat that is additionally dissipated by the infrared emitter, thereby preventing other components of the base from being damaged by heat. Specifically, it mainly targets the heat dissipated below the infrared emitter, and a fan is provided on this basis. The power of the fan here can be selected as a fan with a relatively low power, which is used to blow away the heat of the heat dissipation component, and then blow away the concentrated heat on the heat dissipation component.

[0209] In other words, the heat dissipation component is used to centrally absorb the dissipated heat of the infrared emitter, and then the fan blows towards the heat dissipation component, so as to achieve the heat dissipation effect. Correspondingly, the heat dissipation component can also be made into a dark color, such as black, gray, etc.

[0210] At the same time, on this basis, a corresponding air duct is provided in the base, and the fan is used to blow away the heat of the heat dissipation component, and the outlet of the air duct faces the roller brush. In this way, the cooperation of the fan, the heat dissipation component, the infrared emitter, the air duct, etc. can realize both multiple heating of the roller brush and ensure that the base is not damaged by heat. Specifically, in this solution, the roller brush has both direct heating by the infrared emitter and hot air heating using the heat dissipation component, that is, a set of devices realizes multiple heating. Compared with the heating solutions in the prior art, there are more heating methods and better heating effects.

[0211] In some alternative embodiments, the cleaning device further includes a detection device, and the self-cleaning method includes: controlling the cleaning device to perform a self-cleaning action before executing the drying mode;

[0212] The self-cleaning action includes:

[0213] In response to the self-cleaning instruction, controlling the cleaning device to enter the first cleaning mode, and the first cleaning mode includes a first cleaning stage and a second cleaning stage;

[0214] In the first cleaning mode, controlling the infrared heating device to turn on, the water diverter to spray water, and the roller brush to rotate;

[0215] When the cleaning device executes the first cleaning stage, controlling the detection device to perform a dirt detection on the roller brush, judging the state of the roller brush, and continuing to execute the second cleaning stage; wherein, the state of the roller brush includes a light dirt state, a medium dirt state, and a heavy dirt state.

[0216] In the embodiment of the present application during the self-cleaning process, directly in response to the self-cleaning instruction, and enter the self-cleaning state directly according to this instruction, control to enter the first cleaning mode, and divide the first cleaning mode into two stages. After executing the first cleaning stage, start to execute the dirt detection action. Such a setting can ensure that a cleaning device such as a floor washer can perform the self-cleaning action immediately. If it is set to make a judgment first after obtaining the self-cleaning instruction, then the floor washer will inevitably need to react for a period of time before it can truly intervene in the self-cleaning mode. The reaction time is too slow, the time from obtaining the instruction to the end of the self-cleaning execution is too long, and the user experience is too poor.

[0217] In other words, for the self-cleaning method provided by the present application, no matter what cleaning mode it is, the first cleaning mode will be executed immediately, and the first cleaning mode is configured such that the infrared heating device is turned on, the water distributor sprays water, and the roller brush rotates. In this way, it can be ensured that the first cleaning mode can use hot water for heating. So, at the initial stage of self-cleaning, such a setting can help dissolve dirt immediately to prepare for different cleaning modes corresponding to different roller brush states later.

[0218] The detection device includes but is not limited to a color sensor, such as: an RGB dirt detector.

[0219] An RGB dirt detector refers to a device with the detection function of the color system (Red Green Blue, RGB).

[0220] The RGB dirt detector can accurately capture color information, brightness information, etc., making it easier to distinguish stains from other environmental information and improving the accuracy of stain recognition. It can also distinguish different degrees of dirt according to color information, brightness information, etc., improving the recognition accuracy of different degrees of dirt.

[0221] In some alternative embodiments, in the first cleaning stage, when the water spray volume of the water distributor reaches 45 - 55 mml, stop spraying water;

[0222] In the second cleaning stage, when the water spray volume of the water distributor reaches 45 - 55 ml, stop spraying water;

[0223] After the water distributor stops spraying water in the first cleaning stage and before the water distributor sprays water in the second cleaning stage, control the suction device to perform the suction action.

[0224] 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.

[0225] The water volume can be controlled by controlling the water spraying time of the water separator. 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, if the duration of the first cleaning stage is set to 6s and the above requirements can be met by spraying water for 2s, then the water separator is controlled to stop spraying water after 2s of spraying water, and the purpose of controlling the above water volume is as follows.

[0226] First: Since it is the initial stage, the degree of dirt of the current floor washer is not clear. Controlling the above water volume can prevent water waste. At the same time, since the infrared emitter has just been started, it takes a certain amount of time to heat up to the target temperature. Controlling the above water volume can ensure that the water temperature can quickly reach a suitable temperature, such as 60°C, etc.

[0227] Second: Since the first cleaning mode is divided into two stages, therefore, allocating a certain amount of water to each stage can achieve multiple small-water-volume cleanings, and can also ensure that the cleaning effect is enhanced while not wasting water.

[0228] The water volumes in the first cleaning stage and the second cleaning stage can be equal or approximately equal.

[0229] 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.

[0230] In some alternative embodiments, when the dirty state of the roller brush is a light dirt state, the cleaning device is controlled to enter the drying mode after the first cleaning mode ends;

[0231] When the dirty state of the roller brush is a medium dirt state, the cleaning device is controlled to enter the soaking wash mode after the first cleaning mode ends, and enter the drying mode after the soaking wash mode is executed;

[0232] The soaking wash mode includes controlling the infrared heating device to turn on, the water separator to spray water, and the roller brush to rotate, and the water spraying volume is between 70-90ml.

[0233] In the above solution, the cleaning methods in the light dirt state and the medium dirt state are introduced. Specifically, when it is judged to be in the light dirt state, the current roller brush can complete the cleaning after two stages of hot water cleaning in the first cleaning mode, that is, there is no need to waste resources or time for other cleanings, and the self-cleaning time can be further controlled and resource waste can be prevented.

[0234] If it is detected as a medium pollution state, after performing hot water cleaning in two stages of the first cleaning mode, it starts to enter the soaking and washing mode. In the soaking and washing mode, it is configured to have a larger water spraying volume. The above water volume is controlled between 70-90 ml (specifically, the water volume can be 70 ml, 80 ml, or 90 ml), ensuring 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 pollution state, the two hot water cleaning stages of the first cleaning mode and the self-cleaning of the soaking and washing mode are utilized to further ensure the cleaning effect of the roller brush.

[0235] In some alternative embodiments, when the state of the roller brush is a heavy pollution state, the cleaning device is controlled to enter the heavy pollution cleaning mode after the end of the first cleaning mode; the heavy pollution cleaning mode includes controlling the infrared heating device to turn on, the water distributor to perform water spraying, and the roller brush to rotate, and the water spraying volume is between 50-70 ml, and controlling the water temperature in the cleaning tank to be between 90-100 °C.

[0236] When it is determined to be in a heavy pollution state, after performing the two hot water self-cleaning stages of the first cleaning mode, it enters the high-temperature self-cleaning (i.e., the heavy pollution cleaning mode). At this time, the water spraying volume is controlled between 50-70 ml to ensure that the above water volume can be quickly heated to 90-100 °C, and high-temperature cleaning and dissolution are achieved by using high temperature and a larger water volume, thereby ensuring the cleaning effect of the above roller brush.

[0237] In other words, the present application provides an intelligent cleaning method. By directly entering the first cleaning mode and dividing it into two stages, and judging the state of the roller brush when performing the second stage, the next cleaning action is determined, which not only ensures the rapid realization 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.

[0238] The water spraying volume in the heavy pollution cleaning mode can be 50 ml, 60 ml, or 70 ml, and the water temperature can be 90 °C or 100 °C, but is not limited thereto.

[0239] In some embodiments, the water temperature in the soaking and washing mode is lower than the water temperature in the heavy pollution cleaning mode. The water volume (i.e., the water spraying volume) in the soaking and washing mode is greater than the water volume in the heavy pollution cleaning mode. Embodiment 3

[0240] The self-cleaning method provided in this embodiment is applied to the cleaning system in any implementation manner of the foregoing 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 distributor are arranged in the floor brush, and a suction device is arranged in the body; a cleaning tank for accommodating the roller brush is provided on the base, and an infrared heating device is arranged in the base for heating the roller brush. The infrared heating device includes an infrared emitter and a transmissive member, and both are located below the roller brush.

[0241] As Figure 9 shown, the self-cleaning method includes:

[0242] S110. In response to a drying instruction, control the cleaning device to enter the 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;

[0243] S120. When the drying mode ends, control the infrared heating device to stop heating;

[0244] S130. Within a preset time after the infrared heating device stops heating, control the roller brush to be in a rotating state.

[0245] The embodiment of the present application provides an infrared heating solution, which uses the infrared heating device to penetrate the entire process of roller brush cleaning, including the self-cleaning process and the centrifugal drying and drying stages. That is, a heating device is used to meet the heating requirements of each stage, and at the same time, it can ensure the maximum efficiency of drying and save energy.

[0246] For example, in the above drying stage, after the infrared heating device executes for a preset time, directly control the infrared heating device to stop heating, but the temperature on the transmissive member is still very high at this time. Thus, 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, only need to turn on the infrared heating device for 25 minutes, and then use the residual heat to complete the heating and drying.

[0247] And in the state of residual heat heating, the roller brush keeps rotating, and the roller brush hairs are attached to the transmissive member, which can realize ironing with the residual heat, so as to ensure that the roller brush hairs are in a flat attached state after drying. At the same time, the rotation of the roller brush can also prevent the roller brush hairs from being attached at an angle all the time, thus avoiding the problem of the roller brush hairs being damaged by heat.

[0248] Exemplarily, the drying instruction can also be an instruction carried in the self-cleaning instruction. After the controller responds to the self-cleaning instruction, it can automatically enter the drying stage after cleaning and centrifugal drying the roller brush.

[0249] In some alternative embodiments, the above step S130 includes: controlling the roller brush to rotate forward and reverse alternately.

[0250] During the reverse rotation of the roller brush, the bristles can be turned up, allowing heat to be more easily transferred to the inside of the roller brush, thereby improving the drying efficiency of the roller brush. During the forward rotation of the roller brush, the contact between the roller brush and the transmissive member can be used to iron the bristles of the roller brush, ensuring that the roller brush is flatter. Therefore, the alternating rotation process of forward and reverse rotations can improve the drying efficiency and drying effect on the basis of reducing the risk of the roller brush being damaged by heat. At the same time, the last action before the roller brush stops rotating can be configured to be a forward rotation. At this time, the roller brush bristles are relatively soft, and using the last action of forward rotation can ensure that the roller brush bristles are even flatter.

[0251] Other steps of self-cleaning in the embodiments of the present application can be referred to those described in Embodiment 2. For example, the aforementioned dehydration stage can be executed before the drying stage, the aforementioned first cleaning mode can be executed during the dehydration stage, and the soaking wash mode or the heavy stain cleaning mode can be executed according to the state of the roller brush, etc., which will not be repeated here.

[0252] Other structures of the cleaning system in the embodiments of the present application can be referred to those described in Embodiment 1. For example, the infrared heating device includes at least one of a heat dissipation member, a reflection member, a blower, and a fixing bracket, etc., which will not be repeated.

[0253] In the embodiments of the present application, the embodiments or implementation manners are described in a progressive manner. On the premise of not being contradictory to each other, various embodiments can be combined to form new embodiments. Embodiment 4

[0254] 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. A roller brush and a water distributor are provided inside the floor brush, and a suction device is provided inside the body; a cleaning tank for accommodating the roller brush is provided on the base, and a detection device and an infrared heating device are provided inside the base. The infrared heating device is used to heat the roller brush. The infrared heating device includes an infrared emitter and a transmissive member, and both are located below the roller brush.

[0255] As Figure 10 shown, the self-cleaning method includes:

[0256] Step S210: In response to a self-cleaning instruction, control the cleaning device to enter the first cleaning mode. The first cleaning mode includes a first cleaning stage and a second cleaning stage; in the first cleaning mode, control the infrared heating device to turn on, the water distributor to spray water, and the roller brush to rotate;

[0257] Step S220: After the cleaning device executes the first cleaning stage, control the detection device to detect the dirt of the roller brush, judge the state of the roller brush, and continue to execute the second cleaning stage.

[0258] During the self-cleaning process of the embodiments of the present application, in direct response to the self-cleaning instruction, the cleaning device directly enters the self-cleaning state according to this instruction, controls to enter the first cleaning mode, and divides the first cleaning mode into two stages. After executing the first cleaning stage, the dirt detection action is started. Such a setting can ensure that a cleaning device, such as a floor washer, can perform the self-cleaning action immediately. If it is set to make a judgment first after obtaining the self-cleaning instruction, then the floor washer will inevitably need to react for a period of time before it can truly intervene in the self-cleaning mode. The reaction time is too slow, the time from obtaining the instruction to the end of the self-cleaning execution is too long, and the user experience is too poor.

[0259] In other words, for the self-cleaning method provided by the present application, regardless of the cleaning mode, the first cleaning mode will be executed immediately, and the first cleaning mode is configured such that the infrared heating device is turned on, the water distributor sprays water, and the roller brush rotates. In this way, it can be ensured that the first cleaning mode can use hot water for heating. So, in the initial stage of self-cleaning, such a setting can help dissolve dirt immediately to prepare for different cleaning modes corresponding to different roller brush states later.

[0260] The dirt detector can be used to detect the degree of dirt.

[0261] For example, in the case of a floor washer, the roller brush states include but are not limited to light dirt, medium dirt, and heavy dirt, and the degree of dirt increases in turn.

[0262] Heating the cleaning water with an infrared emitter can improve the dissolution of dirt and enhance the cleaning effect.

[0263] The self-cleaning process of the embodiments of the present application includes the following stages in sequence: cleaning, drying, and drying, etc. It can be understood that both step S210 and step S220 are steps in the cleaning (also known as water washing) stage of self-cleaning.

[0264] In some alternative embodiments, determining the degree of dirt on the roller brush includes: step S211, determining the roller brush state according to the RGB information detected by the RGB dirt detector.

[0265] The RGB dirt detector refers to a device with the detection function of the color system (Red Green Blue, RGB). It can be understood that the dirt detector can also be other forms of detectors, not limited to this.

[0266] The RGB dirt detector can accurately capture color information, brightness information, etc., and is easier to distinguish stains from other environmental information, improving the accuracy of stain recognition. It can also distinguish different degrees of dirt according to color information, brightness information, etc., improving the recognition accuracy of different degrees of dirt.

[0267] In some alternative embodiments, before step S210, the self-cleaning method further includes:

[0268] Perform a stall test on the rotating brush. The stall test includes controlling the rotating brush to rotate forward or backward alternately, and the reverse rotation angle of the rotating brush is less than 360°.

[0269] The stall test can promptly determine whether there is a stall situation in the rotating brush, perform overcurrent protection on the rotating brush motor, and ensure the safety during use.

[0270] During the reverse rotation process, the reverse rotation angle of the rotating brush being less than 360° can reduce the ejection of dirt such as entanglements from the front of the rotating brush. The dirt can be more 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 rotating brush.

[0271] The forward and reverse rotations of the rotating brush alternately also contribute to further improving the cleaning effect of entanglements. For example: when the rotating brush motor drives the cleaning member to rotate forward, the scraping strip on the floor brush can pick up and cut the entanglements. By reversing the rotating brush, the entanglements tightened on the rotating brush can be loosened. After the entanglements are loosened, the rotating brush can be rotated forward again so that the scraping strip can pick up and cut the entanglements again. In this way, by rotating forward and backward alternately, the entanglements can be better cleaned during the stall test.

[0272] In some alternative embodiments, the reverse rotation angle of the rotating brush is 280° to 340°, and the starting point of the reverse rotation angle is the contact point O between the rotating brush and the transmissive member ( Figure 4 as shown), and the connection line ( Figure 4 the vertical dotted line in the figure) between the contact point and the axis of the rotating brush is perpendicular to the horizontal plane (the horizontal dotted line in the figure).

[0273] The "contact point O" here is referred to Figure 4 as shown, and it is also approximately the tangent point between the horizontal plane and the bottom of the rotating brush 110.

[0274] Exemplarily, the reverse rotation angle of the rotating brush can be 280°, 290°, 300°, 310°, 320°, 330° or 340°.

[0275] A reverse rotation angle of 280° to 340° for the rotating brush can better prevent dirt from being ejected from the front of the rotating brush, and the dirt can be more brought to the dirt suction port of the floor brush.

[0276] Specifically, most of the dirt in the prior art appears in positions such as the roller brush cover, the water distributor, and the squeegee. By using reverse rotation, the dirt in the above-mentioned parts can be better cleaned. The contact position between the roller brush and the base is set as the starting point, and then the reverse rotation angle of the roller brush is controlled between 280° and 340°. This can ensure that the reverse rotation of the roller brush can definitely clean the above-mentioned positions. That is, controlling the reverse rotation by 280° can ensure that the roller brush can clean at least positions including the roller brush cover, etc., so as to achieve the above-mentioned dirt cleaning. And setting 340° can ensure that the above-mentioned dirt will not be driven out by the roller brush, and at the same time, the dirt can be transferred to the above-mentioned dirt suction position, which not only ensures the cleaning effect but also prevents the dirt from appearing in other positions.

[0277] In some alternative embodiments, the stall test for the roller brush includes:

[0278] After controlling the roller brush motor to drive the roller brush to rotate forward for a first preset time, then control the roller brush motor to drive the roller brush to rotate backward for a second preset time;

[0279] In response to the current of the roller brush motor being greater than or equal to a first current value during the forward rotation of the roller brush, and / or in response to the current of the roller brush motor being greater than or equal to a second current value during the reverse rotation of the roller brush, it is determined that the roller brush is stalled; wherein, the second current value is greater than the first current value.

[0280] The stall test can promptly determine whether the roller brush is stalled, provide overcurrent protection for the roller brush motor, and ensure the safety during use.

[0281] In some embodiments, the forward and reverse rotations of the roller brush are repeated alternately at least N times. In response to the current of the roller brush motor during each forward rotation being less than the first current value and the current of the roller brush motor during each reverse rotation being less than the second current value, the stall test passes and the self-cleaning action is executed. 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.

[0282] 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.

[0283] 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.

[0284] Exemplarily, when it is determined that the motor is blocked, the controller can issue a warning to remind the user to manually clean the blocked dirt. In this case, the controller can control the cleaning device and related components of the base station to stop working. After the user clears the blockage and issues a continue self-cleaning instruction again, the controller continues to perform the blocked rotation detection and subsequent self-cleaning actions.

[0285] In some alternative embodiments, the self-cleaning method further includes:

[0286] If the dirt state of the roller brush is a light dirt state, after the first cleaning mode of the cleaning device ends, enter the drying mode;

[0287] If the state of the roller brush is medium dirt or heavy dirt, when the second cleaning stage ends, control the cleaning device to enter the second cleaning mode; wherein, when the roller brush state is medium dirt, the temperature of the cleaning water in the second cleaning mode is lower than when the roller brush state is heavy dirt, and the temperature of the cleaning water in the second cleaning mode.

[0288] In the above solution, the cleaning methods in the light dirt state, medium dirt state and heavy dirt state are introduced. Specifically, when it is judged to be in the light dirt state, the current roller brush can be cleaned after two stages of hot water cleaning in the first cleaning mode, and enter the drying stage, that is, there is no need to waste resources or time for other cleaning, which can further control the self-cleaning time and prevent waste of resources.

[0289] If it is detected as the medium dirt state or the heavy dirt state, after performing two stages of hot water cleaning in the first cleaning mode, start to enter the second cleaning mode. In the second cleaning mode, it is configured to have a larger water spray amount or a higher water temperature, or both, and the infrared heating device remains on. That is, in the medium dirt state or the heavy dirt state, the two hot water cleaning stages of the first cleaning mode and the self-cleaning of the second cleaning mode are used to further ensure the cleaning effect of the roller brush.

[0290] In some alternative embodiments, the self-cleaning method further includes:

[0291] In the second cleaning mode, by providing different water amounts, control the temperature of the cleaning water; wherein, the water amount of the cleaning water is negatively correlated with the temperature of the cleaning water.

[0292] Under the condition that other conditions are the same or approximately the same (such as the infrared emitter power remains unchanged, the heating time is equal or not much different), the larger the water amount of the cleaning water, the lower the water temperature; on the contrary, the smaller the water amount of the cleaning water, the higher the water temperature. The water amount and the water temperature are negatively correlated. By controlling the water amount, the control of the water temperature can be achieved, which is more simple and convenient.

[0293] In some alternative embodiments, the second cleaning mode includes a soaking wash mode. If the dirt state of the roller brush is medium dirty, the cleaning device is controlled to enter the soaking wash mode after the first cleaning mode ends, and enters the spin-drying mode after the soaking wash mode is executed;

[0294] The soaking wash mode includes controlling the infrared heating device to turn on, the water distributor to spray water, and the roller brush to rotate, and the water spray volume is between 70-90 ml.

[0295] For the beneficial effects of soaking wash, refer to the foregoing description and will not be repeated here.

[0296] In some alternative embodiments, the second cleaning mode includes a heavy dirt cleaning mode;

[0297] If the state of the roller brush is heavy dirt, the cleaning device is controlled to enter the heavy dirt cleaning mode after the first cleaning mode ends;

[0298] The heavy dirt cleaning mode includes controlling the infrared heating device to turn on, the water distributor to spray water, and the roller brush to rotate, and the water spray volume is between 50-70 ml, and controlling the water temperature in the cleaning tank to be between 90-100°.

[0299] For the beneficial effects of the heavy dirt cleaning mode, refer to the foregoing description and will not be repeated here.

[0300] In some alternative embodiments, in the first cleaning stage, when the water spray volume of the water distributor reaches 45-55 mml, the water spraying stops;

[0301] In the second cleaning stage, when the water spray volume of the water distributor reaches 45-55 ml, the water spraying stops;

[0302] 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 a suction action. For the beneficial effects here, refer to the foregoing and will not be repeated.

[0303] Optionally, after the foregoing spin-drying mode ends, the drying mode is entered. The self-cleaning method further includes:

[0304] When the drying mode ends, the infrared heating device is controlled to stop heating;

[0305] Within a preset time after the infrared heating device stops heating, the roller brush is controlled to be in a rotating state. For the beneficial effects here, refer to the foregoing and will not be repeated.

[0306] In some alternative embodiments, the base further includes a temperature detector. Both the temperature detector and the infrared emitter are located in the chamber formed by the foregoing reflector and transmissive member together, and the temperature detector infrared emitter is used to detect the air temperature adjacent to the infrared emitter.

[0307] The temperature detector detects the temperature of the cooler air instead of directly detecting the temperature of the hotter infrared emitter or the transmissive member, which helps reduce damage to the temperature detector.

[0308] In some alternative embodiments, the self-cleaning method further includes: controlling the operating parameters of the infrared emitter so that the temperature detected by the temperature detector is 90°C - 120°C, based on which the temperature of the transmissive member can reach 220 - 260°C.

[0309] When the temperature is lower than 90°C, it is difficult for the temperature of the transmissive member to heat the liquid thereon to a relatively high temperature (such as 100°C), while if the temperature is too high, such as higher than 120°C, it will cause the temperature to rise too high, resulting in too much steam and too little water volume. However, 90°C - 120°C can ensure an appropriate amount of water remaining on the transmissive member during the cleaning stage and an appropriate amount of steam formed. That is to say, within this temperature range, it can not only dissolve dirt at high temperature, but also achieve an immersion effect with a certain amount of water, and there is also high-temperature steam for sterilization, which can at least effectively improve the cleaning effect during the cleaning stage.

[0310] The operating parameters include but are not limited to: power, heating duration, etc.

[0311] In some embodiments, the temperature detected by the temperature detector is controlled within 90°C - 115°C. For example: by controlling the operating parameters of the infrared emitter, the temperature detected by the temperature detector is 90°C, 100°C, 110°C, or 115°C.

[0312] In some embodiments, the temperature in the drying stage is set within 90°C - 115°C, preferably 110°C.

[0313] Other content not mentioned in this embodiment is the same as that in Embodiment 2 and will not be repeated.

[0314] Exemplarily, taking a floor washer as an example of the cleaning device, the general process of the self-cleaning process of the floor washer includes:

[0315] S310. The floor washer is connected to the signal input interface of the base through the signal output interface and transmits signals;

[0316] S311. Start the carbon fiber heating tube (i.e., the infrared emitter). When current passes through the carbon fiber, the molecules inside the carbon fiber move, converting electrical energy into heat energy and quickly and evenly transferring it to the external environment in the form of far-infrared radiation to achieve the heating effect;

[0317] Its light radiation is concentrated in the infrared band between 1.5 - 15 μm, and the absorption wavelength of organic substances and the infrared radiation intensity are increased by more than 30% respectively. Therefore, it has a strong infrared radiation effect.

[0318] S312. The user releases a self - cleaning and drying signal (i.e., sends a self - cleaning instruction) to the main control board (i.e., the controller) by pressing the handle button on the floor washer.

[0319] After the base control board receives the signal, it obtains the self - cleaning instruction, turns on the infrared device, performs a stall test, controls the rear - end fan to start, and then the carbon fiber heating tube starts to work, generating infrared radiation with a specific wavelength. The infrared radiation is focused by the reflector and evenly irradiated on the roller brush through the transparent sheet. The roller brush rotates at a uniform speed during the drying process (the roller brush will rotate forward and backward during the process).

[0320] During the cleaning, centrifugal drying, and drying processes after the stall test, the temperature and humidity control system real - time monitors parameters such as the humidity of the roller brush and the drying environment temperature, and automatically adjusts the radiation intensity of the carbon fiber heating tube to achieve more precise drying control.

[0321] The stall test process includes rotating forward for 1 s, and after stopping, rotating backward for 0.8 s, with the reverse rotation angle being 300 - 340°. The purpose of not rotating a full circle during reverse rotation can prevent garbage from being spit out and can also just transfer the garbage to a position close to the sewage suction port. The forward and reverse rotations alternate 5 times (that is, the forward and reverse rotations are alternately executed five times). The reverse rotation angle of the roller brush is 330°. If the current of the roller brush motor is found to be below 2 A during forward rotation, it indicates no stall. If the current of the roller brush motor is greater than or equal to 2 A during forward rotation, it indicates a stall. If the current of the roller brush motor is found to be below 4 A during reverse rotation, it indicates no stall. If the current of the roller brush motor is greater than or equal to 4 A during reverse rotation, it indicates a stall.

[0322] After the stall test, it enters the hot - water washing stage. The hot - water washing is divided into two sections, namely the first cleaning stage and the second cleaning stage. After the first cleaning stage is completed, the RGB dirt detector is used to detect dirt, and different self - cleaning modes are selected according to the dirt degree. Specifically, if it is detected as a light - dirt stage, it directly enters the centrifugal drying stage after the second cleaning stage. For the medium - dirt stage, it enters the soaking - washing stage after the second cleaning stage. For the heavy - dirt stage, it enters the high - temperature washing stage (100 °C) after the second cleaning stage. The water volume in the hot - water washing stage is 100 ml, the water volume in the high - temperature washing stage is 60 ml, and the water volume in the soaking - washing stage is 80 ml.

[0323] The temperature in the centrifugal drying stage is set at 90 °C - 120 °C, preferably 110 °C.

[0324] The infrared emitter is started during the stall test and remains on until the self - cleaning is completed.

[0325] Inside the base, there is an NTC temperature sensor which detects the air temperature. The detected temperature range is controlled between 90°C and 115°C. When the temperature is lower than 90°C, it is difficult for the temperature of the transmissive part to heat the liquid on it to 100°C. When the temperature is higher than 115°C, the temperature will rise too high, resulting in too much steam and too little water. The temperature range of 90°C to 115°C, combined with the above three self-cleaning modes, can ensure appropriate temperature, appropriate water volume, and appropriate steam volume, which can not only dissolve dirt at high temperature, but also achieve a certain degree of water immersion and sterilize with high-temperature steam.

[0326] S317. At the same time, after the spin-drying is completed, the drying stage is entered. During the drying stage, the infrared emitter continues to heat, and both the spin-drying stage and the drying stage can iron the roller brush. After the drying is completed, the infrared emitter stops heating, but the roller brush does not stop rotating immediately. Instead, it continues to rotate forward and backward alternately to utilize the residual heat for heating and avoid the risk of the roller brush being burned out. For this reason, after the spin-drying is completed, the roller brush continues to rotate for a certain period of time. The blower can be turned on throughout the process.
