Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Along with the diversification of people's demand, current intelligent cleaning equipment can realize multiple functions, consequently can be applicable to a plurality of application scenes. The inventor discovers through long-term research that when the existing intelligent cleaning equipment simultaneously starts the disinfection function of high-temperature steam and the cleaning function of synchronously collecting dust, part of steam and stains can be sucked away at the same time, so that the cleaning efficiency is affected. To improve or solve the above-described problems, the present application proposes at least the following embodiments.

An exemplary structure of the cleaning device is described below for the cleaning device embodiments of the present application.

The cleaning device 1 may be a device having at least one of dust collection, sweeping, mopping, and washing functions. For example, the cleaning device 1 may be a cleaner, a sweeper, a mopping machine, a floor washing machine, or a robot having functions of sweeping, mopping, or the like, or may be a cleaning device 1 such as a robot with a function of sucking, mopping, or the like. As shown in fig. 1, 2 and 3, the cleaning device 1 includes a housing 100, a liquid supply assembly 200, a stain adsorption assembly 300. The liquid supply assembly 200 and the stain adsorption assembly 300 may be disposed in the housing 100 and connected to the outside through a passage provided separately, for example, water may be injected into the liquid supply assembly 200 through a water pipe by a faucet. At least one of the liquid supply assembly 200 and the stain adsorption assembly 300 can also be detachably arranged outside the shell 100, so that liquid can be conveniently added to the liquid supply assembly 200, and stains in the stain adsorption assembly 300 can be conveniently poured and cleaned. Optionally, the cleaning device 1 may also comprise a liquid mixer (not shown).

The housing 100 includes a main body housing 110 and a cleaning housing 120 connected to each other. The stain adsorption assembly 300 in the main housing 110 includes a stain receiving cavity 310 and a suction assembly 320. The cleaning housing 120 encloses a receiving space 121, and a cleaning assembly 130 and a steam generating assembly 140 are disposed in the receiving space 121. The cleaning housing 120 is provided with a suction port 150. Wherein the suction port 150 and the steam generating assembly 140 may be disposed at opposite sides of the cleaning assembly 130. The housing 100 is further provided with a suction passage 160 communicating the suction opening 150 with the stain receiving chamber 310. The suction passage 160 has a connection passage 161 at the junction of the main body housing 110 and the cleaning housing 120.

The main body housing 110 can be held by a user. The cleaning housing 120 is used for contacting with and cleaning the area to be cleaned, for example, by spraying, rubbing, adsorbing, etc. the area to be cleaned. The main body housing 110 and the cleaning housing 120 are rotatably connected, for example, and a user can adjust the use posture by adjusting the connection angle of the main body housing 110 and the cleaning housing 120. The user can push the main machine housing 110 to further drive the cleaning housing 120 to move in the cleaning area, so as to realize the movable cleaning of the cleaning area.

As shown in fig. 4, the main body housing 110 may include a receiving sub-housing 111 and a holding sub-housing 112 connected in sequence in a length direction, and the receiving sub-housing 111 may be connected with the cleaning housing 120. The end of the accommodating sub-housing 111 away from the cleaning housing 120 is connected to the holding sub-housing 112, and the accommodating sub-housing 111 may be used to accommodate the liquid supply assembly 200, the stain absorbent assembly 300, a liquid mixer (not shown), and the like. The area of the cross section of the grip sub-housing 112 perpendicular to the length direction of the main housing 110 may be smaller than the area of the cross section of the receiving sub-housing 111 perpendicular to the length direction of the main housing 110 so as to be gripped by a user. The end of the holding sub-housing 112 away from the accommodating sub-housing 111 may be provided with a first holding portion 113 for holding a hand of a user. The first grip portion 113 may be provided in a bent shape, for example. The end of the accommodating sub-housing 111 near the holding sub-housing 112 may be provided with a second holding portion 114 for holding by the other hand of the user. The second grip 114 may be, for example, provided in a ring shape. When the user uses the cleaning apparatus 1, the user can hold the cleaning apparatus at the second holding portion 114 by the left hand, hold the cleaning apparatus at the first holding portion 113 by the right hand, and push the cleaning housing 120 through the main housing 110 by the left and right hand dislocation. The second holding part 114 may also be used to move the cleaning device 1, for example, the user holds the cleaning device 1 on the second holding part 114, and places the cleaning device 1 originally placed on the ground on the charging stand for charging.

As shown in fig. 2, 3 and 4, the cleaning assembly 130 is used to contact the region to be cleaned to clean the region to be cleaned, and the liquid supply assembly 200 is used to spray the liquid to the cleaning assembly 130 through the liquid spray port 141. The cleaning assembly 130 may include a roller brush, broom, mop, rag, or the like. The cleaning assembly 130, such as a roller brush, is rotatably disposed in the accommodating space 121 and is driven to rotate by a motor (not shown) that may be fixed to the cleaning housing 120. Wherein, the bottom of the cleaning housing 120 is provided with a mounting space 122, and the suction port 150 faces and communicates with the mounting space 122 for accommodating the cleaning assembly 130. Alternatively, the installation space 122 may be located in the receiving space 121. The installation space 122 has an opening 123, and the cleaning assembly 130 is rotatably received in the installation space 122 and is at least partially exposed through the opening 123. The cleaning assembly 130, such as a roller brush, may be used to contact the area to be cleaned and thereby wipe the area to be cleaned in a rolling friction manner. Optionally, the number of cleaning assemblies 130 is at least one. The number of cleaning assemblies 130, for example, the number of roller brushes, may be one or more, in which case a plurality of roller brushes may be spaced side by side. The cleaning housing 120 is provided with a liquid spraying port 141 spaced apart from the suction port 150. The liquid spraying port 141 may be disposed toward the cleaning member 130 to spray liquid toward the cleaning member 130 so that the cleaning member 130 is wetted, and thus the cleaning member 130 may wet clean an area to be cleaned. Alternatively, the liquid spraying opening 141 may be disposed directly towards the outside of the opening of the accommodating space 121, so as to directly spray the liquid to the area to be cleaned, thereby performing the functions of wetting, rinsing, etc.

The liquid supply assembly 200 is provided at the main body housing 110 and may be used to supply a corresponding liquid to the cleaning housing 120. The liquid supply assembly 200 includes a liquid container 210, which may be used to contain liquid, and a water pump 220, which may be used to deliver the liquid in the liquid container 210 to the cleaning housing 120. Alternatively, the liquid supply assembly 200 may spray the liquid through the liquid spray port 141 to clean the region to be cleaned by the liquid. The liquid supply assembly 200 may also be used to provide liquid to the vapor generation assembly 140. The steam generating assembly 140 includes a heating device 142 and a steam outlet 143. The steam outlet 143 is formed at the bottom of the cleaning housing 120 and is spaced from the opening 123 for outputting steam of the steam generating assembly 140. The liquid supply assembly 200 inputs the liquid into the heating device 142, and the heating device 142 converts the liquid into steam and outputs the steam to the region to be cleaned through the steam outlet 143, thereby performing the functions of high-temperature sterilization and softening of stains. Optionally, the number of water pumps 220 is at least one. For example, there may be two water pumps 220, one water pump 220 for delivering liquid to the liquid spray port 141 and the other water pump 220 for delivering liquid to the vapor generation assembly 140. In the case of cleaning the same area, the amount of liquid used for converting the liquid into the vapor is smaller than that of the liquid used directly, and therefore, the flow rate of the liquid supplied to the liquid ejecting port 141 is larger than that of the liquid supplied to the vapor generating device 140, that is, two different water pumps 220 are required. The liquid delivered by the liquid supply assembly 200 may include, in addition to fresh water, a cleaning agent, a cleaning liquid, and the like. Wherein the cleaning liquid is obtained by mixing clean water with a cleaning agent. Optionally, the number of liquid containers 210 is at least one. For example, the liquid containers 210 may be two in number and may be used to provide at least two liquids to a liquid mixer (not shown). The liquid mixer (not shown) may mix at least two liquids, mix them uniformly, and the like to obtain a mixed cleaning liquid. The mixed cleaning liquid may be sprayed to the cleaning region through at least one of the liquid spray port 141 and the steam outlet 143 after being outputted to the cleaning housing 120, so that the cleaning housing 120 may conveniently perform a cleaning process on the cleaning region using the cleaning liquid.

The stain adsorption assembly 300 can adsorb stains such as garbage of an area to be cleaned, waste water generated during cleaning, and the like during cleaning of the area to be cleaned. The suction assembly 320 serves to suck the soil of the region to be cleaned into the soil receiving cavity 310 through the suction port 150 and the suction channel 160. The suction assembly 320, the stain receiving chamber 310 and the suction port 150 may be directly connected such that stains, such as water and debris, enter from the suction port 150 and are directly introduced into the stain receiving chamber 310 under the suction of the suction assembly 320. Optionally, a pipeline may be disposed between the soil accommodating chamber 310 and the suction port 150, and soil such as water and garbage may enter the soil accommodating chamber 310 through the pipeline from the suction port 150 under the suction action of the suction assembly 320. Alternatively, the suction assembly 320, the soil accommodating chamber 310, and the cleaning assembly 130 may be connected to absorb waste water generated during the cleaning process of the cleaning assembly 130 to the region to be cleaned and soil such as trash on the region to be cleaned. For example, the roller brush 131 may remain with part of the dirt such as the sewage adsorbed to the roller brush 131 or the hair adhered to the roller brush 131 while cleaning, and the dirt may not pass directly through the suction port 150. The soil on the roller brush 131 enters the soil accommodating chamber 310 through the communication channel 161 between the soil accommodating chamber 310 and the roller brush 131 by the suction of the suction assembly 320. Alternatively, the stain receiving chamber 310 may filter the air flow, and the filtered air flow is discharged to the outside of the receiving sub-housing 111.

Further, a detection sensor 170 is disposed in the housing 100, and the detection sensor 170 may be, for example, an infrared pair tube sensor. Alternatively, the infrared pair tube sensor may be stationary or mobile. In the infrared pair-pipe sensor, there is at least one emitter and at least one receiver, wherein the emitter can emit infrared signals, the receiver can receive the infrared signals, when the condition of passing or remaining stains increases, the infrared rays are shielded by the stains, and the signal intensity received by the receiver is weakened or even disappears. The change in signal strength received by the receiver can be used to determine whether or not there is a blockage situation and the degree of blockage, i.e., to detect the presence of dirt passing through or remaining in the suction channel 160.

Alternatively, the position detected by the detection sensor 170 may be the suction port 150, the entire suction passage 160, or a part of the suction passage 160 such as the communication passage 161. For example, the detection sensor 170 may be used to detect the condition of the stain passing through or remaining in the communication channel 161 and transmit the signal to the controller 180, so that the controller 180 determines whether the condition of the stain reaches a preset condition. The detection sensor 170 is disposed at the outer side of the preset position, which is beneficial to preventing dirt from being blocked in the process of being sucked into the dirt accommodating cavity 310 under the action of the suction assembly 320, and also avoiding the dirt from polluting or damaging the detection sensor 170. Alternatively, the detection sensor 170 may be provided inside the specified position. For example, the detection sensor 170 may be disposed outside the communication channel 161 and corresponds to a preset position in the communication channel 161 corresponding to a preset condition, and configured to detect whether the stain reaches the preset position in the communication channel 161, and transmit the signal to the controller 180, so that the controller 180 correspondingly determines whether the stain condition reaches the preset condition. The preset position corresponding to the preset condition is a position where the detection sensor 170 detects the stain condition, for example, a position where the infrared pair tube sensor uses infrared rays. The predetermined position may be a position where the soil is left in the process of being sucked into the soil receiving cavity 310 by the suction assembly 320, and the left position is a position where the soil is accumulated to a predetermined condition. For example, the preset position may be set as a throat of the communication channel 161 between the main body housing 110 and the cleaning housing 120, and the detection sensor 170 is disposed outside the throat and corresponds to the inside of the throat of the communication channel 161 for detecting whether the retention position of the stain in the communication channel 161 has reached the throat position. When the dirt remains in the communication channel 161, the dirt is accumulated, the occupied space position is extended downward until reaching the throat position, and the signal of the detection sensor 170 is weakened or vanished when the dirt accumulated reaches the throat. Therefore, whether the stain reaches the preset position can be judged by detecting the change of the signal intensity of the detection sensor 170, so as to judge whether the condition of the remained stain reaches the preset condition. The preset position may also be a position through which the stain passes during the suction into the stain receiving cavity 310. For example, when the preset position is a throat, the detection sensor 170 is disposed outside the throat and corresponds to the inside of the throat of the communication channel 161, for detecting stains passing through the throat. The signal from the detection sensor 170 is reduced when a small amount of dirt passes through the throat, but the amplitude of the signal reduction is smaller. When a large amount of dirt passes through the throat, the signal of the detection sensor 170 is reduced by a larger extent, and the intensity of the signal received by the receiver in the detection sensor 170 is smaller. Therefore, the stain condition of the preset position at this time can be judged by detecting the intensity of the signal detected by the detection sensor 170, so as to judge whether the passing stain condition reaches the preset condition.

Further, a controller 180 is provided in the housing 100. Optionally, the controller 180 may be provided to the main body housing 110 and/or the cleaning housing 120. For example, at least one controller 180 may be provided in the main body housing 110, at least one controller 180 may be provided in the cleaning housing 120, and at least one controller 180 may be provided in each of the main body housing 110 and the cleaning housing 120. As shown in fig. 5, the controller 180 is electrically connected to the detection sensor 170, the steam generating assembly 140, and the pumping assembly 320. The controller 180 may select to turn on different functions according to a plurality of modes provided for different application scenarios. For example, the user may select a corresponding mode according to whether the steam is required to be used for the region to be cleaned, and the controller 180 may control the steam generating assembly 140 to be in an on state or an off state according to whether the steam is required in the mode selected by the user, thereby controlling the on or off of the steam function. When the cleaning apparatus 1 sucks the soil, the detection sensor 170 detects the soil condition and transmits a related signal related to the soil condition to the controller 180, and the controller 180 may be configured to receive the related signal related to the soil condition transmitted from the detection sensor 170, so as to determine whether the soil condition detected by the detection sensor 170 reaches a preset condition. After the determination, the controller 180 may control the power of the pumping assembly 320 so that the pumping assembly 320 may use different powers in different application scenarios. For example, when the user wants to perform steam sterilization while cleaning an area to be cleaned using the cleaning apparatus 1, the steam mode of the cleaning apparatus 1 may be selected, and the controller 180 determines that steam needs to be turned on in the mode, and then controls the steam generating assembly 140 to be turned on to control the steam function to be turned on. When the steam function is turned on, the suction unit 320 sucks the soil in the area to be cleaned, and when the soil is sucked to the preset position, the detection sensor 170 starts to detect the soil condition at the preset position, and transmits a detected signal related to the soil condition to the controller 180, and the controller 180 determines the soil condition at the preset position and controls the operation power of the suction unit 320 according to the determination result.

Further, the controller 180 needs to receive the detection result signal of the detection sensor 170 to respond accordingly, so as to control the pumping assembly 320. When the steam function is turned on, that is, during the steam output of the steam generating assembly 140, when it is determined that the soil condition detected by the detection sensor 170 does not reach the preset condition, the controller 180 controls the pumping assembly 320 to operate at a first power lower than the preset power. The suction assembly 320 is controlled to operate at a first power lower than a preset power, at which time the steam generated by the steam generating assembly 140 is not sucked into the soil accommodating chamber 310, and protection of the steam output is achieved while effectively recovering the soil. Before the soil condition does not reach the preset condition, the controller 180 may detect a level corresponding to the soil condition according to the soil condition detected by the detection sensor 170, and control the pumping assembly 320 to operate at a first power value matched with the level corresponding to the soil condition according to the detected level. By setting a plurality of levels and a plurality of first power values, the suction force of the suction assembly 320 can be adjusted according to the actual stain condition while the suction assembly 320 is kept to operate at a low power, i.e. the steam output is protected to the greatest extent, so that the effective recovery of the stains can be realized. The controller 180 controls the pumping assembly 320 to operate at a second power higher than or equal to the preset power when it is determined that the soil condition detected by the detection sensor 170 reaches the preset condition. When the condition of the passing or remaining dirt reaches the preset condition, it indicates that the dirt condition of the area to be cleaned is more at this time, and although the steam may be partially affected at this time, the power of the suction assembly 320 should be increased in a short time so as to increase the suction force, thereby realizing effective recovery of the dirt. And when the steam function is turned off, i.e., when the steam generating assembly 140 is in the off state, the controller 180 is used to control the pumping assembly 320 to operate at a third power higher than or equal to the preset power. The suction assembly 320 should be controlled to be turned on as high power as possible when no steam is generated so that the soil can be rapidly sucked into the soil receiving cavity 310, thereby effectively improving cleaning efficiency. The controller 180 controls the operation power of the suction assembly 320 according to the actual stain condition, so that the influence of the suction process on the output steam can be effectively reduced when the suction function and the steam function are simultaneously started, the output steam is protected while effective cleaning is ensured, the cleaning efficiency is improved, and meanwhile, the cleaning area can be effectively cleaned when only the suction function is started, and the cleaning efficiency is improved.

Optionally, a controller 180 may be provided in the cleaning housing 120, and an inertial measurement unit (Inertial Measurement Unit, IMU) may be provided in the controller 180, which may be configured to sense the status of the cleaning device 1, such as forward, backward, raised. Through the IMU's perception of the status of the cleaning device 1, the controller 180 can predict the user's actions or needs, thereby improving the user's satisfaction.

The controller 180 may be used to perform a control method of the cleaning device 1, for example the controller 180 may store a corresponding computer program to perform the control method of the cleaning device 1 when the computer program is executed. As shown in fig. 6, a detailed exemplary description of a control method embodiment of the cleaning apparatus of the present application will be given below, mainly with the controller 180.

S100: during the process of outputting steam by the steam generating component, the detection sensor detects the condition of the dirt passing through or remaining in the suction channel.

The detection sensor 170 may detect a soil condition within the suction channel 160, i.e., the location at which the soil condition is detected may be the suction channel 160. For example, when the detection sensor 170 is disposed outside the suction channel 160, it can detect the condition of dirt passing through or remaining in the suction channel 160. Optionally, the detection sensor 170 may also detect the stain condition through the suction port 150, the stain condition through the suction channel 160, and the stain condition through both the suction port 150 and the suction channel 160, depending on the operational power of the suction assembly 320 and the stain condition corresponding to the scene. Likewise, the detection sensor 170 may also detect the presence of dirt that is left alone in the suction channel 160. Thus, the locations at which the stain condition is detected may include the suction channel 160, the suction port 150, and the suction channel 160 and the suction port 150. For example, when the detection sensor 170 is disposed outside the suction port 150, the detection sensor 170 can detect and determine the contamination passing through the suction port 150. Alternatively, the number of the detection sensors 170 may be more than one, for example, may be two, one disposed outside the suction port 150 and one disposed outside the suction passage 160. The detection sensor 170 disposed outside the suction port 150 may be used to detect and determine the condition of the dirt passing through the suction port 150; the detection sensor 170 provided outside the suction passage 160 detects and determines the condition of dirt passing through the suction passage 160. The two detection sensors 170 can make the position selection of detection and judgment more flexible, and can further judge the stain condition, thereby obtaining a more accurate and reliable judgment result.

Alternatively, detection of the condition of the stain passing through the suction port 150, the suction passage 160, and both the suction port 150 and the suction passage 160 may be, for example, detection of the amount of the stain passing through the above-mentioned positions. For example, may include calculating the time required for the stain to pass through the location, such as the suction channel 160, for a certain length, and may also include calculating the length of the stain passing through the location, such as the suction channel 160, for a certain time. Alternatively, the presence of dirt in the suction channel 160 may also be detected, for example the amount of dirt remaining in the suction channel 160 may be detected. For example, it may include calculating the time required for the stain to fill a certain volume of the above-described position, for example, the suction passage 160, i.e., the retained stain, to reach a preset position, for example, the time required for the stain to accumulate to the throat position of the communication passage 161 when the stain is retained in the communication passage 161, and if the accumulated time to occupy the throat position is 0.001 cubic meter, the required time is 1 minute, the amount of the stain is 1 cubic meter/minute. It may also include calculating the volume of the aspiration channel 160 that the stain occupies over time. Alternatively, the detection of the condition of the passing or remaining soil may not be an exact value, for example, it may also be detected whether the soil has reached a preset position when the soil condition has accumulated to some extent. For example, when the stain detected by the detection sensor 170 reaches the preset position, a corresponding signal may be sent to the controller 180, and the controller 180 determines the received signal.

S200: judging whether the stain condition detected by the detection sensor reaches a preset condition.

After detecting the soil condition, the controller 180 determines whether the soil condition detected by the detection sensor 170 reaches a preset condition. The soil condition may include a soil amount, which may be, for example, a volume of the soil, a quality of the soil, and the like. The preset condition is a threshold value of the stain condition passing through or remaining, for example, the threshold value of the stain amount can be used. And if the condition of the passing or remaining stains exceeds the threshold value of the condition of the stains, judging that the preset condition is reached. And if the condition of the passing or remaining stains does not exceed the threshold value of the condition of the stains, judging that the preset condition is not reached. For example, the threshold value of the amount of the stain passing through or remaining is 2 cubic decimeters per minute, and if the detected amount of the stain is 1 cubic decimeter per minute, the preset condition is judged not to be met; if the detected stain amount is 2.1 cubic decimeter/min, it is determined that the preset condition is reached. Alternatively, the threshold soil condition may not be an exact value, but may be a predetermined location. For example, when the detection sensor 170 is disposed outside the throat of the communication channel 161 and when the stain remains in the communication channel 161, if the throat is set to a preset position, that is, the throat is a stain condition threshold, the controller 180 determines that the remaining stain condition exceeds the stain condition threshold once the stain has accumulated to the throat position of the communication channel 161, that is, the signal detected by the detection sensor 170 is in a stable weakened state. Because the passing dirt can cause the infrared signal of the detection sensor 170 to be blocked, but only the infrared signal is blocked briefly, when the dirt is accumulated to the position, the signal can be regarded as being in a stable weakening state, and the dirt condition can be judged to exceed the dirt condition threshold value at the moment, namely, the preset condition is reached.

S300: the pumping assembly is controlled to operate at a first power that is lower than a preset power.

During the steam output of the steam generating assembly 140, the controller 180 determines that the soil condition detected by the detection sensor 170 does not reach a preset condition, i.e., when the soil condition passing through or remaining in the detected suction channel 160 does not reach a soil condition threshold, the controller 180 may control the suction assembly 400 to operate at a first power lower than the preset power. Since the preset power is a high power, at which the soil cannot remain in the suction channel 160 but is sucked into the soil accommodating chamber 310, part of the steam generated by the steam generating assembly 140 is sucked into the soil accommodating chamber 310, thereby reducing the cleaning efficiency. The first power is lower than the preset power, and has little or no effect on the steam generated by the steam generating assembly 140, and at this time, protection of the steam output can be achieved while effectively recovering stains. Alternatively, at the first power, the stain is not sucked into the stain receiving cavity 310, but remains in the suction channel 160. Alternatively, the stain may be partially or entirely drawn into the stain receiving chamber 310, but the power is now less and the steam generated by the steam generating assembly 140 is less or not drawn in. For example, the preset power may be 75% p, 80% p, 85% p, and the first power may be 10% p, 15% p, 20% power.

S400: the pumping assembly is controlled to operate at a second power that is greater than or equal to the preset power.

When it is determined that the stain condition detected by the detection sensor 170 reaches the preset condition, the controller 180 controls the pumping assembly 320 to operate at a second power higher than or equal to the preset power during the steam output of the steam generating assembly 140. The second power is higher than or equal to the preset power, for example, the second power may be 85% p, 90% p, 100% p. At the second power, the suction assembly 320 increases the suction force on the stain so that the stain can be sucked from the suction channel 160 into the stain receiving cavity 310. When the condition of the passing or remaining dirt exceeds the threshold value, i.e. the preset condition is reached, it may be alternatively considered that the suction channel 160 is already filled with dirt, i.e. the dirt cannot be continuously loaded, and it may be considered that the dirt condition of the area to be cleaned is more, so that the power of the suction assembly 320 should be increased at this time to increase the suction force, so as to realize effective dirt recovery. The time that the suction assembly 320 is operated at the second power is limited, and after the suction assembly 320 is operated at the second power for a while, i.e., the soil in the suction channel 160 has been entirely sucked into the soil receiving cavity 310, the soil condition can be again judged.

The actual situation at the time of cleaning may change, for example, the area to be cleaned may change, and the area to be cleaned may change from a place where the situation of stains is less to a place where the situation of stains is more, for example, the situation of stains in the area to be cleaned may change from less to more. The method of changing the operation power of the pumping unit 320 by determining whether the stain condition detected by the detection sensor 170 reaches the preset condition is a continuous determination process, and may be continuously changed according to the actual situation. By constantly varying the power of the suction assembly 320, the impact of the suction process on the output steam can be effectively reduced while effectively recovering the soil.

Since the various functions of the cleaning device are separately and independently implemented, a user can select different modes of the cleaning device 1 according to actual application scenarios. The controller 180 may control the steam generating assembly 140 to be in an off state when, for example, the cleaning apparatus 1 is turned on for an intelligent mode of the scene when the steam function is not required but only cleaning of only some of the easily cleaned stains present in the area to be cleaned is required and the use of the steam function is not required. When the cleaning area needs to be sterilized by high temperature steam or there is a stain difficult to clean at this time, the cleaning apparatus 1 turns on the steam mode for the scene, and the controller 180 may control the steam generating assembly 140 to be in an on state. The control method shown in fig. 6 is applied to the process of outputting steam by the steam generating assembly 140, so that it should be determined whether the steam generating assembly 140 is in the on state before the method, as shown in fig. 7, specifically, reference may be made to the following steps included before S100:

s110: it is determined whether the steam generating assembly is in an on state.

S120: if not, the pumping assembly is controlled to operate at a third power higher than or equal to the preset power.

When it is determined that the steam generating assembly 140 is in the off state, the controller 180 controls the pumping assembly 320 to operate at a third power higher than or equal to the preset power. Because the steam generating assembly 140 does not generate steam at this time, the power of the pumping assembly 320 at this time does not affect the steam. Therefore, the power should be turned on as high as possible at this time so that the soil can be rapidly sucked into the soil accommodating chamber 310, thereby effectively improving cleaning efficiency. The third power should be higher than or equal to the preset power, for example 85% of the preset power, and the third power may be 90% p, 100% p.

When it is determined that the steam generating assembly 140 is in the on state, the detection sensor 170 has not yet started detecting the stain condition. The controller 180 is configured to determine that the stain condition detected by the detection sensor 170 does not reach the preset condition during the steam output of the steam generating assembly 140 and to control the pumping assembly 320 to operate at the first power lower than the preset power. Since the suction of the dirt is not started or just started when the cleaning device 1 is just turned on, the dirt situation is very small and the output of steam should be protected as much as possible, so the first power at this time should take a low value, for example 15% p. After a certain period of operation of the cleaning device 1, dirt has been sucked into the cleaning device 1, the detection of the dirt condition by the detection sensor 170 is only started.

Optionally, before the stain condition reaches the preset condition, the power of the suction assembly 320 may be changed according to the stain condition, specifically, reference may be made to the following steps included before S200:

s130: judging the grade corresponding to the stain condition.

Before the soil condition reaches the preset condition, the controller 180 may be configured to detect a corresponding level according to the soil condition detected by the detection sensor 170, and set different levels, such as a first level and a second level, according to different soil conditions, such as different amounts of soil, which are all less than the threshold of the soil condition passing or remaining. For example, when the soil is a soil amount, the first level may correspond to a soil amount of 1 cubic meter/minute and the second level may correspond to a soil amount of 1.5 cubic meters/minute when the threshold amount of soil that passes or remains is 2 cubic meters/minute. The first grade may be judged when the detected amount of soil passing through or remaining is greater than 1 cubic decimeter/minute and less than 1.5 cubic decimeter/minute. The second grade may be judged when the detected amount of soil passing or remaining is greater than 1.5 cubic decimeters per minute. Based on the determination of the level of the soil condition by the controller 180, the controller 180 is configured to control the pumping assembly 320 to operate at a first power level that matches the level corresponding to the soil condition.

S140: the suction assembly is controlled to operate at a first power level that matches a level corresponding to a soil condition.

Alternatively, the first power may include a plurality of first power values at which the suction assembly 320 draws different amounts of soil. The first power value matches a class corresponding to the soil condition. For example, when the first power is 15% p, when the first level is determined, the pumping component 320 is controlled to adjust the power to 20% p of the first power value corresponding to the first level; when the second level is determined, pumping element 320 is controlled to adjust the power to 30% p of the first power level corresponding to the second level. By setting a plurality of first power values, the suction force of the suction assembly 320 can be adjusted according to the actual stain condition while the suction assembly 320 is kept in low-power operation, namely, the steam output is protected, so that the effective recovery of the stains can be realized.

Alternatively, different levels may be set according to the soil conditions treated in different modes. For example, the cleaning apparatus 1 may have a conventional mode and a steam mode in both of which the controller 180 controls the steam generating assembly 140 to output steam. However, the two modes are different in application, in which the steam mode is mainly to sterilize the cleaning area with high temperature steam, and there is not much dirt, so the suction assembly 320 is not required to operate at a higher power. If the steam pattern is associated with the first level, the stain condition is lower, i.e. the first power value associated with the first level should be lower. While in the conventional mode steam sterilization is only an adjunct, where cleaning is primarily performed on the area to be cleaned, the amount of soil is greater and the suction assembly 320 is required to operate at a slightly higher power. If the normal mode is associated with the second level, the stain condition will be higher, i.e. the first power value associated with the second level should be higher.

In summary, by detecting the condition of the dirt passing through or remaining in the suction port 150/the suction passage 160 of the cleaning apparatus using the detection sensor 170, it is detected and judged whether the condition of the dirt currently sucked satisfies the preset condition. When the stain condition does not satisfy the preset condition, the controller 180 controls the suction assembly 320 to operate at a first power lower than the preset power, i.e., to operate at a lower power, so that the influence of the suction process of the suction assembly 320 on the steam is reduced while the stain can be sucked, and the amount of the steam sucked by the suction assembly 320 is reduced, thereby realizing the protection of the output steam, so that more steam remains in the area to be cleaned as much as possible, and the area to be cleaned is cleaned more effectively, and the cleaning efficiency is improved.
